A pipe enlarging device includes a base, an operation unit and a clamping unit. The clamping unit is received in the base, and includes movable front and rear clamps and a front threaded rod. The front and rear clamps are resiliently movable when the front threaded rod is rotated so as to form an adjustable clamping area between the front and rear clamps. The clamping area is used to clamp pipes of different sizes. The operation unit includes a top threaded rod with a cone-shaped member which is used to enlarge the inner diameter of the pipes.

Pipe enlarging device

A pipe enlarging device includes a base, an operation unit and a clamping unit. The clamping unit is received in the base and includes movable front, rear, left and right clamps, multiple resilient members and a front threaded rod. The front, rear, left and right clamps are resiliently movable when the front threaded rod is rotated so as to form an adjustable clamping area between the front, rear, left and right clamps. The clamping area is used to clamp pipes of different sizes. The operation unit includes a top threaded rod with a cone-shaped member which is used to enlarge the inner diameter of the pipes.

A power and signal transmission device for a spindle of a machine tool is provided. The power and signal transmission device includes a spindle fixing portion, a shaft rotating portion, a power transmission component and a signal transmission component. The spindle fixing portion is provided with a power input end, a primary side power induction coil, a secondary side signal induction coil and at least one signal output end. The shaft rotating portion is provided with a joining end surface for bonding to a holder, a secondary side power induction coil and a primary side signal induction coil, and is rotatable with respect to the spindle fixing portion. The power transmission component transmits an electrical energy from the power input end. The signal transmission component transmits a holder signal to the signal output end. Each of the power and signal transmission components includes at least one elastic pogo pin.

A machining thermostatic control system and method of using the same are disclosed. The system comprises a detecting unit, a processing unit and at least a cooling unit. The detecting unit is used for detecting the temperature distribution of a workpiece. The processing unit is coupled to the detecting unit and is used for processing the temperature distribution for obtaining a position of maximum hot spot of the workpiece. The cooling unit comprises a head which is provided for discharging cooling fluid and a plurality of blades which are angle-adjustably mounted to the head. The blades are coupled to the processing unit and the angle of blades are controlled by the processing unit for enabling the cooling fluid to flow toward to the position of maximum hot spot position.

A jaw wrench includes two first bodies, a second body a function end unit and a control unit. The first bodies each have a first toothed hole. The second body has a second toothed hole. The function unit includes a third body and a fourth body pivotably connected to the third body. The third body has a first toothed portion and is connected to the second body. The fourth body has a second toothed portion. An object is clamped between the first and second toothed portions. The control unit has two control members, two second resilient members and two covers. The two control members extend into the two first and second bodies and each have a third toothed hole which is engaged with the first/second toothed hole. When the control members are pushed, the third toothed holes are disengaged from the first toothed hole.

Jaw wrench

A clamping and positioning device includes a base, a rotary member, a moving assembly and an elastic member. The rotary member is rotatably disposed on the base and includes a stopping surface facing the base. The moving assembly includes a moving member movably disposed on the base to have a first and a second position. When being at the first position, the moving member is pressed against the rotary member to allow the stopping surface to apply a normal force to the base; when being at the second position, a gap is formed between the moving member and the rotary member so the normal force applied by the stopping surface of the rotary member is released from the base. The elastic member has two ends connected to the base and the moving member, respectively. The elastic member normally causes the moving member to be at the first position.

Clamping and positioning device and operation method thereof

A wrench includes a first part, a second part and a third part. The first part has a first toothed portion and a first pivotal portion. The second part has a third pivotal portion which is connected to the first pivotal portion so that the second part is pivoted an angle relative to the first part about the first pivotal portion. The third part is movably connected to the second part and has a second toothed portion which faces the first toothed portion so that objects of different sizes are clamped between the first and second toothed portions.

Wrench for operating objects of different sizes

A monkey wrench includes a body, a first jaw, a second jaw and a press member. The second jaw is linearly movable relative to the body. The first and second jaws each have an operation member which has second teeth defied in on side thereof. The second jaw has first teeth on the top thereof and the press member has third teeth. When pivoting the press member to engage the third teeth with the first teeth, the second jaw is secured. A resilient member is connected to the second jaw which is movable when the press member is pivoted in the opposite direction to disengage the third teeth from the first teeth.

Monkey wrench

A pipe wrench includes a body and a first jaw has one end fixed to the body, and a second jaw is slidably located in a first recess defined in the top of the body and is located beneath the first jaw. A resilient member is connected between the body and the second jaw. A first link has one end pivotably connected to an end of the second jaw. A second link has the first end thereof pivotably connected to the mediate portion of the first link. An adjustment member threadedly extends through a closed end of the body and contacts against the second end of the second link. The second jaw is quickly slid by the resilient member and controlled by the adjustment member, so that the object can be released and clamped quickly.

Pipe wrench

A rotation mechanism includes a mandrel, a rotation axle, a needle roller bearing and an angular bearing. The mandrel includes a shaft portion, a first annular contact portion and a second annular contact portion. The shaft portion has an outer surface, and the first annular contact portion and the second annular contact portion are located on the outer surface and respectively surround the axis of the mandrel. The rotation axle includes an annular portion, a third annular contact portion and a fourth annular contact portion. The annular portion has a shaft hole and an inner surface forming the shaft hole. The third annular contact portion and the fourth annular contact portion are located on the inner surface, and the mandrel passes through the shaft hole. The needle roller bearing is in contact with the first annular contact portion and the third annular contact portion, and is located between them.
