The disclosure is related to a clamp-type measuring device includes a clamp and an interval measuring module. The clamp includes a guiding rail and two holding arm. Each of holding arms includes a guide part, a connecting part, and a clamping part. The guide part is movably furnished on the guiding rail. Both ends of the connecting part are respectively connected to the guide part and the clamping part. The interval measuring module includes a first measuring element and a second measuring element. The first measuring element and the second measuring element are furnished on the two connecting parts respectively. The first measuring element and the second measuring element are slidable through the two guide parts respectively in order to measure an interval between the two clamping parts. In addition, the disclosure is also related to a measuring method of the clamp-type measuring device.

Clamp-type measuring device and measuring method

A hydrostatic bearing assembly for a shaft is disclosed, which consists of a base ring, two side rings enclosed up the base ring at both sides, and a plurality of hydrostatic blocks fixed respectively on surfaces of the base ring and of the side rings corresponded to the shaft, as result to hold the shaft to resist against loadings from the axial direction and/or the radial direction and provide lubrication through oil passages inside. These hydrostatic blocks are locked with screws or bolts on the base ring and on the side rings in order to be replaced individually on site.

Hydrostatic bearing assembly

A hydraulic hydrostatic pressure rotation module has a table piece with a mount face; an oil cavity piece installed on the mount face, having at least one first oil cavity, at least one second oil cavity, at least one third oil cavity, at least one first oil way communicated with the first oil cavity, at least one second oil way communicated with the second oil cavity and the first oil way, at least one third oil way communicated with the third oil cavity and the second oil way, and at least one fourth oil way communicated with the second oil way; a supporting oil seat installed on a face of the oil cavity piece away from the mount face, having at least one oil entry way communicated with the fourth oil way; a spindle through the supporting oil seat and the oil cavity piece and coupled to the table piece.

A device of the axial-directional oil chamber of hydrostatic spindle comprises integrated oil seal structures at both the axial direction and the radial direction. The oil seal structures increase the work area of the oil chamber by extending and thus connecting an axial-directional oil seal edge to a radial-directional oil seal edge. Then, the rigidity of the axial hydrostatic bearing can be increased, and thus the application capability of the hydrostatic spindle can be upgraded to perform the multi-task machining from the mono-task machining.

Device of the axial-directional oil chamber of hydrostatic spindle

A telescopic shaft assembly includes a seat, a shaft body disposed movably in the seat, and a plurality of slide blocks located between the shaft body and the seat. The shaft body has a convex portion and a recessed portion opposite to each other. One end of the convex portion far away from the recessed portion has a top surface. One of the plurality of slide block is disposed on the top surface. The recessed portion has two inner side wall surfaces opposite to each other and a bottom surface located between the two inner side wall surfaces. Each of the two inner side wall surfaces forms an obtuse angle with the bottom surface. Two of the rest of the plurality of slide blocks are disposed on the two inner side wall surfaces respectively.

Telescopic shaft assembly

A braking device includes a base, a braking component, and a driving component including a reset member. The braking component has a clamping block. The driving component includes a movable member, a chamber therein and a first butting portion. The movable member passes through the driving member. One end of the movable member has a piston accommodated in the chamber, and the other end of the movable member has a second butting portion. The reset member is disposed in the chamber. The piston butts the reset member under an external force, and the first butting portion and the second butting portion are kept away from each other, and when the external force vanishes, the reset member butts the piston, and the first butting portion and the second butting portion are kept close to each other so as to achieve a braking effect.

Braking device

The present disclosure relates to a hydrostatic plate bearing, which comprises: a body, and a plurality of restrictors. Wherein, the body is formed with a mounting surface and an oil chamber that are disposed opposite to each other; the plural restrictors includes an orifice restrictor and a membrane restrictor while allowing the orifice restrictor and the membrane restrictor to be serially connected to each other. Operationally, a working fluid that is flowing into the body via the mounting surface is split to flow through the orifice restrictor and the membrane restrictor, in that the split flow of the working fluid that is flowing through the orifice restrictor is guided to flow into the oil chamber.

Hydrostatic plate bearing

Disclosed is a supporting bearing for providing a large rotary module with an axial supporting force. The supporting bearing includes a body, a sliding track and a plurality of rolling members, wherein the sliding track is embedded in the body, and the rolling members are disposed so as to roll in the sliding track and to protrude from the top of the body, thereby providing higher precision and better rigidity to the large rotary module.
