[0002] Automotive wiring harness foaming process is a manufacturing process that uses polymer materials to react and form a polyurethane foam layer on the surface of the wiring harness. It is mainly used to improve the insulation, mechanical cushioning and environmental adaptability of the wiring harness.

[0003] Existing patent application number: 202022747743.9 A foamed wire harness structure includes a foam body, a chamfered square tube segment, a chamfered rhomboid tube segment, a torsion transition surface, a foamed inner cavity, and bundled corrugated tubes. The foam body is composed of an integrally formed and coaxially connected chamfered square tube segment and a chamfered rhomboid tube segment. A torsion transition surface is provided between the chamfered square tube segment and the chamfered rhomboid tube segment. The foam body has a foamed inner cavity in its core. The cross-sectional shape of the foamed inner cavity is shaped like a quincunx pattern. Four bundled corrugated tubes are inserted into the foamed inner cavity in a quincunx arrangement to fit the foamed inner cavity.

[0004] The aforementioned patent describes a foamed wire harness structure. After the automotive wire harness undergoes foaming treatment, a trimming machine is needed to polish the outer foam layer of the wire harness to smooth out burrs and unevenness on the surface, making it smoother. In practical applications, when performing the trimming operation, workers need to hold the wire harness close to the polishing wheel. If the force is not applied properly, it is easy to hit the rotating polishing wheel and cause a safety accident, resulting in low safety. Therefore, we propose a trimming device for the foaming process of automotive wire harnesses to solve the above problems. Utility Model Content

[0011] Preferably, a cover plate is hinged to the left side of the machine base, and two grooves are symmetrically arranged on the left side of the top surface of the machine base. The grooves are symmetrically arranged on the front and rear sides of the mounting cavity. The cover plate is fitted into the inner side of the groove through the bottom two sides, so that the cover plate flips over and covers the top of the mounting cavity.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention incorporates a safe trimming device. When polishing the foam layer of a wire harness, the motor is first started to drive the polishing wheel. Then, the wire harness is inserted and placed inside the sleeve. Subsequently, one hand operates the handwheel to turn the No. 1 screw, which controls the movement and adjustment of the guide frame to adjust the contact distance between the wire harness and the polishing wheel. The other hand holds the wire harness and pushes and rotates it to adjust the polishing position, thus achieving the polishing and trimming of the wire harness. During the operation, the worker does not need to hold the wire harness and make close contact with the polishing wheel for trimming, greatly reducing the risk of accidents and effectively improving operational safety.

[0014] This invention features a wire harness clamping device on the surface of the guide frame. By inserting the wire harness through the inside of the clamp and then turning the second screw with a knob, the clamp is moved by the second screw to tighten the wire harness inside.

[0022] Please see Figure 1-4 This utility model provides a trimming device for automotive wiring harness foaming process, including a safety trimming device 1. The safety trimming device 1 includes a machine base 11, a mounting cavity 12, a motor 13, a grinding wheel 14, a guide frame 15, a threaded sleeve 16, a No. 1 screw 17, a handwheel 18, and a wiring harness clamping device 19. The mounting cavity 12 is provided on the left side of the top surface of the machine base 11. The motor 13 is embedded in the bottom surface of the mounting cavity 12. The top output shaft of the motor 13 is connected to the grinding wheel 14. The grinding surface of the grinding wheel 14 has an arc-shaped groove 141. The grinding wheel 14 can be more effectively trimmed through the arc-shaped groove 141. The machine base 11 is equipped with a sliding rail on the right side of the top surface to improve the efficiency of the trimming work. The sliding adjustment distance of the guide frame 15 is 5-8cm, which has sufficient adjustable margin to better control the contact distance between the wire harness and the grinding wheel 14. A threaded sleeve 16 is installed on the right edge of the top surface of the machine base 11. A screw 17 is screwed into the inner thread of the threaded sleeve 16. The first end of the screw 17 is rotatably connected to the guide frame 15 by a bearing. A handwheel 18 is installed at the end of the screw 17. A wire harness clamping device 19 is provided on the surface of the guide frame 15.

[0023] Specifically, when polishing the foam layer of the wire harness, first start the motor 13 to drive the polishing wheel 14 to rotate, then insert the wire harness into the inner side of the sleeve 191. Then, operate the handwheel 18 with one hand to turn the first screw 17, and control the guide frame 15 to move and adjust through the first screw 17 to adjust the contact distance between the wire harness and the polishing wheel 14. Hold the wire harness with the other hand to push and rotate it to adjust the polishing position of the wire harness, thereby achieving the polishing and trimming of the wire harness. During the operation, the worker does not need to hold the wire harness and make close contact with the polishing wheel 14 for trimming and polishing, which greatly reduces the risk of accidents and effectively improves the safety of operation.

[0024] Please see Figure 5 This utility model provides a trimming device for automotive wiring harness foaming process.

A foam pad 194 is pasted and laid on the surface of the guide frame 15. The foam pad 194 is located inside the clamp 191 and plays an elastic buffering role to prevent the clamp 191 from completely clamping the wiring harness, which would prevent the wiring harness from rotating and adjusting the grinding position.

[0025] Specifically, when installing the wire harness, first insert the wire harness through the inside of the clamp 191, and then turn the second screw 192 with the help of the knob 193. The second screw 192 drives the clamp 191 to move and tighten the wire harness inside. This can properly clamp the wire harness and prevent the wire harness from loosening and moving on its own, which would affect the trimming accuracy of the grinding wheel 14.

[0026] To further explain, a cover plate 110 is hinged to the left side of the machine base 11. Two grooves 111 are symmetrically arranged on the left side of the top surface of the machine base 11. The grooves 111 are symmetrically arranged on the front and rear sides of the mounting cavity 12. The cover plate 110 fits into the inner side of the grooves 111 through the bottom two sides, so that the cover plate 110 flips and covers the mounting cavity 12.

[0027] Specifically, the grinding wheel 14 inside the mounting cavity 12 is shielded and protected by the cover plate 110 to prevent the grinding wheel 14 from accidentally coming into contact with foreign objects, thus effectively improving safety. Moreover, the grinding wheel 14 can be disassembled and replaced simply by opening the cover plate 110, without affecting the normal replacement operation of the grinding wheel 14.
