Description

Technical Field

[0001] The present application relates to the technical field of clamping tools, and in particular to a rotor and head cover clamping tool. Background Art

[0002] The production of subway traction motors usually includes multiple processes, one of which requires fixing a copper head cover on the end of a copper wire. The wire end includes two wire ends, which are formed by consolidating multiple copper wires and are distributed in rectangular blocks. The head cover is in the shape of a rectangular frame and is mounted on the joint of the two wire ends. Fixing the head cover on the wire end can ensure the stability and firmness of the wire, so that it can better withstand various environmental conditions and vibrations during subway operation.

[0003] In the prior art, a vise is usually used to press the parallel head cover onto the end of the wire to fix the parallel head cover to the end of the wire; the vise includes a jaw, a jaw arm, a hinge and a handle, the jaw is U-shaped, and both sides are fixed to the jaw arm in the form of concentric circles, and the inner side of the jaw is serrated, the jaw arm is usually arc-shaped, and the jaw and the hinge are respectively connected on both sides of the jaw arm, the hinge is a joint connecting the jaw arm and the handle, usually U-shaped, used to support the bending of the jaw arm and adjust the clamping strength of the jaw part, the handle is a straight rod and has a certain length; the parallel head cover and the end wire are pressed against each other by a vise; the vise includes a jaw, a jaw arm, a hinge and a handle, the jaw is U-shaped, and both sides are fixed to the jaw arm in the form of concentric circles, and the inner side of the jaw is serrated, the jaw arm is usually arc-shaped, and the jaw and the hinge are respectively connected on both sides of the jaw arm, the hinge is a joint connecting the jaw arm and the handle, and is usually U-shaped, used to support the bending of the jaw arm and adjust the clamping strength of the jaw part, and the handle is a straight rod and has a certain length; When fixing, the staff must first select the appropriate jaw size according to the size specifications of the parallel head cover, and then clamp the parallel head cover with the jaws and ensure that the inner wall of the jaws is completely in contact with the outer wall of the parallel head cover. After adjusting the jaw position, apply force to the handles to make the handles close to each other, and the handles drive the clamp arms to rotate along the hinge axis to adjust the clamping force of the jaws until the required force is reached, and then press the parallel head cover against the end of the wire to fix the parallel head cover and the end of the wire. Finally, stop applying force to the handles and move the handles away from each other to take out the fixed parallel head cover and the end of the wire.

[0004] Regarding the above-mentioned related technologies, since the contact area between the jaws of the pliers and the parallel head cover is large, the force-bearing area of ​​the parallel head cover increases, and the connection performance between the parallel head cover and the wire end cannot be guaranteed, affecting the fixing effect of the parallel head cover and the wire end.

At the same time, the first hand-held portion 22 and the second hand-held portion 32 drive the first clamping portion 2 and the second clamping portion 3 to move away from each other through the hinge shaft 1 during the process of moving away from each other, thereby driving the first clamping section 2 12 and the second clamping section 312 are away from each other and form a clamping cavity for fastening the parallel head cover and the wire end, and then the parallel head cover and the wire end are placed in the clamping cavity so that the ends of the first clamping section 212 and the second clamping section 312 that are close to each other abut against the two opposite side walls of the parallel head cover, and then force is applied to the first hand-held part 22 and the second hand-held part 32 so that the first hand-held part 22 and the second hand-held part 32 are close to each other, and the first hand-held part 22 and the second hand-held part 32 drive the ends of the first clamping section 212 and the second clamping section 312 that are close to each other through the hinge shaft 1 to gradually approach each other, and squeeze against the two opposite side walls of the parallel head cover, firmly fasten the parallel head cover head to the joint of the two guide wire ends, and realize the fixed connection between the guide wire end and the parallel head cover, finally, adjust the first clamping part 2 and the second clamping part 3 to separate, and remove the fixed parallel head cover and the wire end.
