Description

Technical Field

[0001] This utility model relates to the field of motor production equipment technology, and in particular to motor wire harness clamp crimping tooling. Background Technology

[0002] During the assembly process of motor manufacturing, it is necessary to bind multiple wire bundles leading from the stator winding together; such as Figure 1 As shown, during the constraint process, a flexible sleeve 11 is typically first fitted onto the outside of multiple wire harnesses 10. Then, a U-shaped metal wire harness clamp 12 is snapped onto the outside of the sleeve 10. Finally, the vertical edges on both sides of the wire harness clamp 12 are bent inwards to securely bind the multiple wire harnesses 10 together. In existing technology, this bending process is usually done manually. The operator needs to stabilize the multiple wire harnesses and the wire harness clamp (which are already fitted with the sleeve) with one hand, while using needle-nose pliers or other tools with the other hand to bend the vertical edges of the wire harness clamp until it fits snugly against the sleeve. This manual bending method has disadvantages such as high labor intensity, low efficiency, and poor quality consistency.

[0003] Based on this, the applicant is considering designing a motor wire harness clamp crimping tool that can reduce labor intensity, improve efficiency, and enhance quality consistency. Utility Model Content

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is: how to provide a motor wire harness clamp crimping tool that can reduce labor intensity, improve efficiency, and enhance quality consistency.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The motor wiring harness clamp crimping fixture includes a crimping head and a placement block; One end of the pressure head is a connecting end that is fixedly connected to the lifting part of the stamping device, and the other end is a free end. The placement block is fixedly installed directly below the free end of the pressure head; a clamping groove is provided on the free end.

[0006] The working principle and advantages of this motor wire harness clamp crimping fixture are as follows: In use, multiple wire harnesses, each fitted with a flexible sleeve and equipped with a U-shaped wire harness clamp, are placed on the placement block with the vertical edges of the clamps facing the pressure head. The lifting part of the stamping device is then lowered, causing the pressure head to move downwards. The clamping groove aligns with the vertical edges of the wire harness clamps and applies pressure downwards simultaneously, bending the vertical edges inwards until they are flush against the outer wall of the sleeve, thus completing the crimping and reliably binding the multiple wire harnesses together. Afterwards, the lifting part of the stamping device is raised, causing the pressure head to move upwards, allowing the clamped wire harnesses to be removed. This solution achieves simultaneous bending of both vertical edges with a single press, eliminating the need for repeated manual operations, effectively reducing labor intensity and improving processing efficiency. When processing the same batch of motors, the clamping groove size is fixed, the bending angle and clamping force are consistent, resulting in a neat crimped appearance and maintaining consistent processing quality. This also minimizes damage and inconsistent quality caused by manual operation.

[0007] Furthermore, the clamping groove is a radially penetrating arc-shaped groove.

[0008] Furthermore, the junction between the arc-shaped groove and the free end face is rounded.

[0009] Furthermore, the pressure head connection end is detachably connected to the lifting part, and the pressure head connection end is provided with a first screw hole.

[0010] Furthermore, the top sidewall of the placement block is provided with a placement groove that penetrates the left and right sidewalls of the placement block, and the placement groove is a U-shaped groove.

[0011] Furthermore, an avoidance groove is provided on the right side wall of the placement block.

[0012] Furthermore, the left side wall of the placement block has a through hole that communicates with the clearance groove.

[0013] Furthermore, it also includes an adjustment seat and a fixed mounting seat; the adjustment seat is detachably connected to the fixed mounting seat, and the placement block is detachably connected to the adjustment seat.

[0014] Furthermore, a second screw hole is provided on the bottom side of the placement block, and a third screw hole corresponding to the second screw hole is provided on the adjustment seat, with at least two of both the second screw hole and the third screw hole.

[0015] Furthermore, the fixed seat has a T-shaped groove, in which a T-shaped nut is disposed, and the adjusting seat has an adjusting groove, in which a locking bolt is threadedly connected to the T-shaped nut is disposed. Attached Figure Description

[0018] Refer to together Figure 2 and Figure 3This embodiment provides a motor wiring harness clamp crimping fixture, which includes a crimping head 200 and a placement block 300; One end of the pressure head 200 is a connecting end that is fixedly connected to the lifting part 110 of the stamping device 100, and the other end is a free end. The placement block 300 is fixedly installed directly below the free end of the pressure head 200; a clamping groove 210 is provided on the free end.

[0019] In this embodiment, during use, multiple wire harnesses 10, each fitted with a flexible sleeve 11 and equipped with a U-shaped wire harness clamp 12, are placed on the placement block 300, with the vertical edges of the wire harness clamp 12 facing the pressure head 200. Then, the lifting part 110 of the stamping device 100 is lowered, and the pressure head 200 moves downwards with the lowering part 110. The clamping groove 210 applies pressure synchronously downwards to the vertical edges of the wire harness clamp 12, causing the vertical edges of the wire harness clamp 12 to bend inwards until they are tightly against the outer wall of the sleeve 11, completing the crimping and reliably binding the multiple wire harnesses 10 together. Then, the stamping device 100 is controlled to... The lifting part 110 of the 0 rises, and the pressing head 200 moves upward with the lifting part 110, so that the crimped wire harness 10 can be taken out. This solution can complete the synchronous bending of both vertical sides with one pressing, without the need for repeated manual operation, which can effectively reduce labor intensity and improve processing efficiency. When processing the same batch of motors, the size of the clamping groove 210 is fixed, the bending angle and the clamping force are consistent, the crimped appearance is neat, and the consistency of processing quality can be maintained. At the same time, it can avoid damage and inconsistent quality caused by manual operation as much as possible.

[0020] Preferably, such as Figure 3 As shown, the clamping groove 210 is a radially penetrating arc-shaped groove; the arc-shaped groove radially penetrates the free end of the pressure head 200, and the inner arc radius of the arc-shaped groove matches the distance between the outer edge of the vertical side of the U-shaped wire harness clamp 12, so as to ensure that the vertical side is subjected to uniform force and no local deformation during the crimping process, so that the two vertical sides of the wire harness clamp 12 can be bent synchronously and uniformly to fit the sleeve 11 and the multiple wire harnesses 10 inside.

[0021] Preferably, such as Figure 3 As shown, the connection between the arc groove and the free end face is rounded at 220 to avoid stress concentration at the root of the vertical edge of the U-shaped wire harness clamp 12 during crimping, and to ensure a smooth bending transition and that the sleeve 11 and the wire harness 10 inside are not damaged; specifically, the radius of the arc groove is 6.8 mm and the radius of the rounded corner 220 is 2 mm.

[0022] Preferably, such as Figure 3As shown, the connecting end of the press head 200 is detachably connected to the lifting part 110, and the connecting end of the press head 200 is provided with a first screw hole 230; the connecting end of the press head 200 and the lifting part 110 of the stamping device 100 adopt a detachable connection structure, which facilitates quick replacement of press heads 200 of different specifications or maintenance of the press head 200; the first screw hole 230 is provided axially at the connecting end, and the detachable connection between the press head 200 and the lifting part 110 can be realized by fixing a stud that is threaded to the first screw hole 230 on the lifting part 110 of the stamping device 100.

[0023] Preferably, such as Figure 4 and Figure 5 As shown, the top side wall of the placement block 300 is provided with a placement groove 310 that runs through the left and right side walls of the placement block 300. The placement groove 310 is a U-shaped groove. The placement groove 310 is a U-shaped groove that matches the outer contour of the U-shaped wire harness clamp 12. It is used to position and support the wire harness clamp 12 and the sleeve and wire harness 10 inside it, so that the staff can center the wire harness clamp 12 and the sleeve and wire harness 10 inside it, while avoiding movement.

[0024] Preferably, such as Figure 4 , Figure 5 and Figure 8 As shown, a clearance groove 320 is provided on the right side wall of the placement block 300. The clearance groove 320 allows a portion of the stator 20 connected to multiple wire harnesses 10 to be inserted. The wire harness clamp 12 generally constrains the multiple wire harnesses 10 led out from the winding of the stator 20, and the part of the wire harness clamp 12 that constrains the wire harnesses 10 is close to the connection point between the stator 20 and the wire harnesses 10. When crimping with the wire harness clamp 12, the operator holds the stator 20 connected to the wire harnesses 10 with one hand and the free end of the wire harnesses 10 with the other hand, and inserts a portion of the stator 20 into the clearance groove 320 to avoid interference between the stator 20 and the placement block 300. At the same time, the bottom side of the stator 20 can contact the bottom side of the clearance groove 320 to provide support for the operator. This support can prevent the operator's hand from being suspended in the air and subjected to force. The operation is intuitive and labor-saving.

[0025] Preferably, such as Figure 4 and Figure 5 As shown, the left side wall of the placement block 300 is provided with a through hole 330 that communicates with the clearance groove 320; the through hole 330 can reduce the weight of the placement block 300 and reduce the material used in the placement block 300; the through hole 330 also makes it convenient for the operator to insert their fingers to hold the wire harness 10 or the stator 20, forming clearance space and facilitating operation.

[0026] Preferably, such as Figure 2 , Figure 6 and Figure 7As shown, the motor wiring harness clamp crimping fixture also includes an adjusting seat 400 and a fixed seat 500; the adjusting seat 400 is detachably connected to the fixed seat 500, and the placement block 300 is detachably connected to the adjusting seat 400; the adjusting seat 400 can adjust the position of the placement block 300 on the fixed seat 500, thereby adjusting the position of the placement block 300; and the adjusting seat 400 and the fixed seat 500 are detachably connected, and the placement block 300 and the adjusting seat 400 are detachably connected, which facilitates the replacement and maintenance of the motor wiring harness clamp crimping fixture; specifically, the fixed seat 500 is fixedly connected to the bottom of the stamping device 100.

[0027] Preferably, such as Figure 2 , Figure 5 and Figure 6 As shown, the placement block 300 has a second screw hole 340 on its bottom side, and the adjusting seat 400 has a third screw hole 420 corresponding to the second screw hole 340. There are at least two second screw holes 340 and at least two third screw holes 420 on the top side of the placement block 300. The second screw holes 340 and the third screw holes 420 are fastened with bolts to realize the detachable fixation of the placement block 300 on the adjusting seat 400 and to ensure positioning accuracy and connection strength.

[0028] Preferably, such as Figure 2 , Figure 6 and Figure 7 As shown, the fixed base 500 has a T-shaped groove 510, in which a T-shaped nut 520 is disposed. The adjusting base 400 has an adjusting groove 410, in which a locking bolt 530 is threadedly connected to the T-shaped nut 520. The upper surface of the fixed base 500 has a T-shaped groove extending transversely (in the direction of the placement block 300), in which a T-shaped nut is slidably disposed. The adjusting base 400 has a rectangular adjusting groove 410 extending longitudinally (in the direction of the placement block 300), and the locking bolt 530 passes through the adjusting groove 410 and is threadedly connected to the T-shaped nut 520. The nut is threaded and connected; loosening the locking bolt 530 allows the adjusting seat 400 and the placement block 300 to move longitudinally or laterally, enabling bidirectional position adjustment of the placement block 300 in the horizontal plane. After adjustment, tightening the locking bolt 530 locks the adjusting seat 400 and the placement block 300 to the fixed seat 500. This facilitates adjustment of the position of the placement block 300 according to actual conditions, improving the applicability and flexibility of the motor wiring harness clamp crimping tool.
