A cylinder body includes a first guide surface made up from first guide grooves and a first bulging portion, wherein a slide table is displaceably supported on the first guide surface via a guide mechanism. Additionally, guide members of a guide block that constitutes the guide mechanism are inserted into and fixed within the first guide grooves. Further, the cylinder body is equipped with a second guide surface, which is formed with substantially the same shape as the first guide surface. In the event that the first guide surface is oriented upwardly and the slide table is installed thereon, the second guide surface acts as a mounting surface, whereas, in the event that the second guide surface is oriented upwardly and the slide table is installed thereon, the first guide surface acts as the mounting surface.

Linear actuator

An inner member having a supply port is installed at the inside of a housing, wherein the housing and the inner member are connected together by connecting bolts. Air is supplied to the supply port of the inner member and is directed and introduced through communication passages into an annular passage. Thereafter, the air is directed outwardly from a plurality of lead-out holes, which communicate with the annular passage, in a swirling direction with respect to an annular recess facing the workpiece. In addition, by having the air flow along the annular recess, which is formed with a substantially trapezoidal shape in cross section, the workpiece is maintained in a non-contact state with respect to a holding surface of the inner member.

Disclosed is a pressure-adjusting mechanism comprising a pressure-adjusting handle, a pressure-adjusting screw for adjusting resilient force of a spring member by making rotation integrally with the pressure-adjusting handle, and a pressure-setting scale for indicating a preset pressure value by rotating the pressure-adjusting handle in a predetermined direction. As a result, it is possible to obtain the pressure-adjusting mechanism which is constructed integrally with a pressure control valve owing to a simple structure and which makes it possible to easily adjust the pressure by an operator.

Disclosed is a pressure/flow rate control valve comprising a pressure-adjusting section having a valve plug for reducing the pressure of a pressure fluid flowing through a clearance between a hole and itself, a stem which is displaceable integrally with the valve plug and which is installed with a packing, and a spring member which is fastened to one end of the stem, for pressing the valve plug toward an annular projection formed on an inner wall surface of a first valve body.

Pinching of the fingers of an air chuck is prevented during opening or closing in order to allow them to open or close smoothly and to miniaturize the air chuck. In a linear guide air chuck having a rod that is operated by an air cylinder mechanism; a pair of fingers is provided that can be opened and closed to grip a workpiece; a guide mechanism moves the fingers linearly to open or close them; and a pair of levers convert operation of the rod into the opening and closing operation of both fingers the lever and finger being coupled together by fitting a spherical engagement element formed on the lever so, in a circular engagement hole cut in the top surface of the finger, at a position at which the acting force of the lever can be transmitted to the finger at nearly the same height as that of the guide mechanism.

Linear guide air chuck

A chuck device has a pair of grippers pivotally supported in a recess defined in an end of a body for angular movement about a predetermined angle, a joint member connected to a piston reciprocally movably disposed in a cylinder chamber defined in the body, and a pair of rollers engaging respectively in grooves in the grippers and angularly movably mounted on the joint member. Linear movement of the piston can be transmitted as angular movement to the grippers through the rollers while the rollers are angularly moving with respect to the joint member. A cover is mounted on the end of the body in closing relation to the recess.

Chuck device

A linear actuator comprising a guide section formed along a longitudinal direction to protrude on a bottom surface of a slide table, a pair of guide blocks formed mutually opposingly and seperated from each other by a predetermined spacing distance on an upper surface of the main cylinder body, attachment holes for attaching the main cylinder body to another member in any direction of attachment from a side of the slide table or from a side of the main cylinder body, and an adjuster bolt for adjusting an amount of displacement of the slide table.

Piston rods are coupled to respective pistons movably disposed respective cylinder chambers defined in a cylinder body. The piston rods have distal ends connected to an end plate mounted on a slide table which is mounted for movement along a guide rail. When the piston rods are displaced by the pistons, the slide table is also displaced axially of the cylinder body. When the slide table is positioned at either end of its stroke, a load is applied by the weight of a workpiece supported on the slide table and the weight of the slide table itself to the cylinder body through the guide rail. The slide table is thus prevented from being unduly flexed under the load. The length of the slide table can be set to a desired length irrespective of an increase in the displacement of the slide table. Even if the displacement of the slide table is increased, the slide table is not flexed and hence remains highly rigid against flexure.

Actuator with slide table

A linear actuator has an actuator body having a through hole defined axially therein and an opening defined in an upper surface thereof, a pair of end blocks, a slide table reciprocally movable in the directions indicated by the arrows X, Y, a pair of cylindrical members coupled to the end blocks, respectively, and having respective passages communicating with fluid outlet/inlet ports, respectively, defined in the actuator body, a joint member movable in unison with the slide table, a pair of cover members held in surface-to-surface contact with the joint member in confronting relation to each other and hermetically surrounding outer circumferential surfaces of the cylindrical members, for sliding displacement in unison with the slide table, and a pair of pressure chambers defined by the cylindrical members and the cover members and closed by the cover members, the pressure chambers communicating with passages in the cylindrical members.

A linear actuator has a cylinder body having a slot defined therein, a slide table, a joint connected substantially perpendicularly to a lower surface of the slide table, a pair of pistons slidably disposed in a through hole defined in the cylinder body and defining respective cylinder chambers in the through hole, for displacing the joint in response to a fluid under pressure supplied to one of the cylinder chambers, a guide projecting from a lower surface of the slide table, a pair of spaced guide blocks projecting from an upper surface of the cylinder body, and a plurality of balls rollingly interposed between the guide and the guide blocks.

In a slide actuator, a central guide rail having V-shaped grooves defined therein and opened at 90 degree angles, is mounted on a cylinder body. A slide table is brought into engagement with the guide rail. Guide members having V-shaped grooves defined therein are provided inside the slide table so that they are opposed to the grooves defined in the guide rail. Cylindrical roller bearings are alternately fitted at inclinations of 90.degree. in their corresponding channels defined by the opposed grooves. Thus, when the roller bearings are rolled, the slide table is displaced with higher accuracy and a load supported by the slide table is transmitted to the guide rail from the roller bearings.

Slide actuator

A tool fastening apparatus for industrial robots comprises a coupling unit attached to the arm of a robot and a coupling unit attached to a tool to be used with the robot. When the two coupling units are joined together, their relative position can be easily and accurately fixed by means of positioning couplings comprising ball rings carrying a set of annularly arranged balls slightly sticking out from the plane of contact between the two coupling units. Accurate positioning is achieved by bringing the balls on the two ball rings into engagement, which, in turn, is achieved by fitting each ball on one ball ring into between two adjoining balls on the other ball ring.
