Technical Field
[0001] This utility model relates to the field of automotive wheel speed sensor manufacturing technology, specifically a wire twisting mechanism after core wire stripping. Background Technology
[0002] The vehicle wheel speed sensor accurately and quickly transmits the wheel speed signal detected by the wheel speed sensor to the vehicle's electronic control unit, enabling the various control systems of the vehicle to obtain wheel speed data in real time and realize the coordinated work between different systems.
[0003] In the production process of automotive wheel speed sensor wiring harnesses, problems often arise such as the copper wires becoming detached after the wire core is stripped, leading to short circuits during subsequent welding processes. Furthermore, it is difficult to calibrate and position the wiring harness according to the different sizes of the harnesses when they are moved, which affects the accuracy of the wiring harness processing and twisting, and reduces the production quality.

[0010] Preferably, the guide rod and the guide sleeve are respectively a cross-shaped rod body and a cross-shaped sleeve structure. The guide sleeves of the two cross-shaped sleeve structures are slidably engaged with the guide rods of the cross-shaped rod body structure. Through the guiding engagement of the cross-shaped structure, it is easy to maintain the rotation of the guide rod and adjust the distance between the two sets of limiting discs as needed.
[0011] Preferably, the top of the guide groove is provided with a notch, and the notch is opposite to the horizontal plane of the clamping mechanism, so that the core wire that needs to be twisted can pass through the notch and be guided into the clamping mechanism for clamping and fixing.

At this point, the lifting cylinder drives the lifting seat to rise and fall, causing the upper and lower tracing plates below the lifting seat to contact and be positioned. Then, the upper and lower tracing plates move horizontally towards each other, using the displacement of the tracing plate structure to twist the core wire once, completing the twisting action after stripping the core wire. By utilizing the structure of this automated equipment, problems such as the copper wires spreading after stripping the wire harness core wire and short circuits occurring in the next welding process are solved.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1-5 The present invention provides an embodiment of a wire stripping and twisting mechanism, comprising a base 1 and a mounting base 4. A bracket 2 is mounted on the top of the base 1. A lifting cylinder 3 is provided at one end of the bracket 2. A lifting seat 5 is provided at the output end of the lifting cylinder 3. An upper twisting plate transverse movement cylinder 6 is provided at the bottom of the lifting seat 5, and an upper twisting plate 7 is provided at the output end of the upper twisting plate transverse movement cylinder 6. A lower twisting plate transverse movement cylinder 9 is provided at the bottom of one end of the bracket 2, and a lower twisting plate 8 adapted to the upper twisting plate 7 is provided at the output end of the lower twisting plate transverse movement cylinder 9.
[0023] The top of the mounting base 4 is provided with a clamping mechanism 41 and a guiding mechanism 42;
[0024] The clamping mechanism 41 includes a clamping cylinder and a clamping plate, and the clamping plate and the lower rubbing plate 8 are on the same horizontal plane. The upper rubbing plate lateral movement cylinder 6 and the lower rubbing plate 8 are in close contact. The upper rubbing plate 7 and the lower rubbing plate 8 move horizontally towards each other. By utilizing the structure of opposite rubbing motion, the wire twisting action of the wire harness is completed.
[0025] The guiding mechanism 42 includes a guide groove 421, which is installed on the top of one end of the mounting base 4. Guide rods 422 are sleeved on the top of both sides inside the guide groove 421, and guide sleeves 423 are sleeved on the outside of the guide rods 422. Limiting discs 424 are installed on the outside of the two guide sleeves 423.
[0026] A servo motor 425 is provided at the bottom of the guide groove 421. A bidirectional lead screw 427 is sleeved at the middle position of both sides inside the guide groove 421. A matching moving block 428 is provided on the outside of the bidirectional lead screw 427. A bearing seat 429 is provided on the top of the moving block 428. Two guide sleeves 423 are connected to the bearing seat 429. A bevel gear set 426 that meshes with each other is provided at the output end of the servo motor 425 and the outside of the bidirectional lead screw 427.
[0027] The top of the guide groove 421 is provided with a notch, and the notch is opposite to the horizontal plane of the clamping mechanism 41, so that the core wire that needs to be twisted can pass through the notch and be guided into the clamping mechanism 41 for clamping and fixing.
[0028] Example 1, as Figure 1-3 As shown, the clamping mechanism 41 includes a clamping cylinder and a clamping plate, and the clamping plate and the lower rolling plate 8 are on the same horizontal plane. By activating the clamping cylinder of the clamping mechanism 41, the clamping plate can be opened, closed or clamped, thereby positioning the wire harness, keeping the sensor communication line in a stable state for rolling, and improving the accuracy and quality of rolling.
[0029] Example 2, as Figure 1-5 As shown, the guide rod 422 and the guide sleeve 423 are composed of a cross-shaped rod body and a cross-shaped sleeve structure, respectively. The guide sleeve 423 of the two cross-shaped sleeve structures slides in cooperation with the guide rod 422 of the cross-shaped rod body structure. Through the structural cooperation between the guide rod 422 and the guide sleeve 423 of the cross-shaped structure, when the twisted pair is introduced into the twisting structure for twisting work, the start of the servo motor 425 drives the bevel gear set 426 to mesh and cause the bidirectional lead screw 427 to rotate synchronously. Then, the bidirectional lead screw 427 drives the moving block 428 to move towards each other, causing the moving block 428 to drive the bearing seat 429 and the guide sleeve 423 to move outside the guide rod 422 for spacing adjustment. This allows the width of the limiting plate 424 to be adjusted according to the size of the twisted pair, so that the twisted pair to be twisted is centered and stably introduced into the clamping mechanism 41 for positioning. Thus, by utilizing the guiding and adjustment functions of the structure, the twisting efficiency of the twisted pair bundle is improved.
[0030] Working principle: This is the wire twisting mechanism after the core wire is stripped;
[0031] First, the wire harness is automatically transported from the previous process to the clamping mechanism 41 on the top surface of the mounting base 4. The clamping mechanism 41 clamps the wire harness, causing the core wire to be exposed outside the clamping claws. At this time, the lifting cylinder 3 can be activated to drive the lifting base 5 and the upper scouring plate horizontal movement cylinder 6 to descend, causing the upper scouring plate 7 connected to the upper scouring plate horizontal movement cylinder 6 to descend to the designated position. At this time, the upper scouring plate horizontal movement cylinder 6 and the lower scouring plate horizontal movement cylinder 9 can be activated to drive the upper scouring plate 7 and the lower scouring plate 8 to move towards each other, pressing and twisting the wire harness, causing the exposed core wire to twist towards each other, thus twisting the core wire once, completing the twisting action.
