Description

Technical Field

[0001] This invention relates to the field of wire harness processing technology, and in particular to a wire harness abrasion device for preventing the accumulation of abrasive debris. Background Technology

[0002] Automotive wiring harnesses are the main network of automotive circuits. Without wiring harnesses, there would be no automotive circuits. A wiring harness is an assembly that connects circuits by crimping copper contact terminals (connectors) with wires and cables, and then molding an insulator or adding a metal shell on the outside.

[0003] Among them, grinding is an important step in the wire harness production process. The grinding process is a key step to ensure the surface quality of the outer sheath (insulation layer), which directly affects the wear resistance, adhesion and electrical performance of the wire harness.

[0004] A search revealed a Chinese patent document titled "A Polishing Machine for Wire Harness Production" with authorization announcement number CN220481130U. The document describes a wire harness being passed through a polishing hole in a ring-shaped mold (with an internal ring-shaped fine polishing section and a coarse polishing section) for rotary polishing. However, during actual polishing, the polishing hole is a relatively closed and narrow space. The long wire harness passing through it occupies most of the space within the hole, preventing sufficient space for the abrasive particles to diffuse and dissipate freely. The accumulated abrasive particles fill the spaces between the diamond abrasive particles, hindering sufficient contact between the particles and the outer surface of the long wire harness. This prevents the abrasive particles from effectively polishing the wire harness surface, resulting in uneven polishing and poor polishing in some areas. Therefore, this application provides a wire harness polishing device to prevent abrasive particle accumulation and meet this requirement. Summary of the Invention

[0005] The purpose of this application is to provide a wire harness polishing device for preventing wear debris accumulation, which solves the technical problem that existing polishing molds easily cause wear debris to accumulate in the polishing holes when polishing wire harnesses.

[0006] To achieve the above objectives, this application provides the following technical solution: a wire harness abrasion device for preventing wear debris accumulation, comprising a first coarse grinding mechanism, a second coarse grinding mechanism, a first fine grinding mechanism, and a second fine grinding mechanism arranged sequentially with identical structures;

[0007] The first coarse grinding mechanism includes mounting plates that are symmetrically arranged on the left and right. A large drive wheel and a small rotating wheel are rotatably arranged on both sets of mounting plates. The large drive wheel and the small rotating wheel are connected by a grinding belt with abrasive particles on its surface. The large drive wheel is driven by a rotary motor mounted on the mounting plate.

[0008] The small rotating wheel is mounted on the slider, the slider is slidably connected to the slide block on the mounting plate, and the side end of the slider is connected to the mounting plate through a connecting spring;

[0009] The two sets of large drive wheels on the first coarse grinding mechanism and the first fine grinding mechanism are arranged opposite each other from left to right;

[0010] The two sets of large drive wheels on the second coarse grinding mechanism and the second fine grinding mechanism are arranged vertically opposite each other.

[0011] Coarse grinding particles are provided on the grinding surfaces of the two sets of grinding belts on the first coarse grinding mechanism and the second coarse grinding mechanism;

[0012] Fine abrasive particles are provided on the grinding surfaces of the two sets of grinding belts on the first fine grinding mechanism and the second fine grinding mechanism;

[0013] The wire harness passes sequentially through the grinding gap formed between the two corresponding sets of grinding belts. One end of the wire harness is mounted on the pay-off machine, and the other end is mounted on the take-up machine.

[0014] A cleaning unit is also provided for cleaning the abrasive shavings adhering to the abrasive belt;

[0015] During operation, the two sets of grinding belts positioned opposite each other move in the same direction.

[0016] In a preferred embodiment of this invention, each set of sliders is provided with two sets of small rotating wheels, which are assembled with the large drive wheel through the grinding belt, and a gap is provided between the two small rotating wheels.

[0017] As a preferred embodiment of this invention, the cleaning unit includes an air outlet pipe disposed on the corresponding mounting plate and a hollow pipe installed at the center of one of the large drive wheel shafts.

[0018] A centrifugal spring is fixed inside the hollow tube, and a movable column is installed at the upper end of the centrifugal spring. Multiple sets of second movable rods are circumferentially arranged on the outer wall of the movable column, and the ends of the multiple sets of second movable rods away from the movable column are movably connected to the corresponding first movable rods. The ends of the multiple sets of first movable rods close to the hollow tube are movably connected to the outer wall of the hollow tube.

[0019] A column is fixed at the upper axis of the movable column, and a ball bearing is installed at the upper end of the column. The upper end of the ball bearing contacts the lower end of the gear. The upper end of the gear penetrates the plate body installed on the mounting plate. A current regulator electrically connected to the vortex blower is provided on the plate body, and a toothed ring that meshes with the gear is installed on the outer wall of the adjustment knob of the current regulator. The air outlet of the vortex blower is connected to multiple sets of air outlet pipes through pipes.

[0020] The air outlet direction of the multiple sets of air outlet pipes is opposite to the rotation direction of the corresponding large drive wheel;

[0021] Initially, the working power of the vortex blower is at its maximum. As the speed of the large drive wheel 108 decreases, the working power of the vortex blower gradually decreases, and the intensity of the airflow ejected from the outlet pipe 5 decreases.

[0022] In a preferred embodiment of this invention, the wire harness is arranged in a stepped distribution and passes through the grinding gap. This part of the wire harness includes multiple horizontal sections and connecting sections for connecting adjacent horizontal sections. Limiting wheels are provided at the corners where the horizontal sections and the connecting sections are connected. The first coarse grinding mechanism, the second coarse grinding mechanism, the first fine grinding mechanism and the second fine grinding mechanism are sequentially arranged at positions 17 relative to the horizontal section 17 of the wire harness.

[0023] In a preferred embodiment of this invention, the connecting portion of the wire harness is inclined to the horizontal plane.

[0024] In a preferred embodiment of this invention, the angle θ between the receiving part and the horizontal line is set to 10° to 30°.

[0025] In summary, the technical effects and advantages of this invention are as follows:

[0026] 1. The present invention has a reasonable structure. By sequentially setting a first coarse grinding mechanism, a second coarse grinding mechanism, a first fine grinding mechanism, and a second fine grinding mechanism, the grinding belts set on the left and right and up and down can be used to polish the wire harness in an all-round way. During the polishing process, the grinding debris generated on the polishing surface can be thrown out by the centrifugal force of the rotating grinding belt. The grinding debris cannot be accumulated at the polishing point, thus achieving good polishing of the wire harness.

[0027] 2. In this invention, two sets of small rotating wheels are provided, so that the grinding belt portion corresponding to the two sets of small rotating wheels can perform surface contact grinding on the same part of the wire harness. Compared with line contact grinding, the contact area between the grinding belt and the wire harness is significantly increased in the surface contact mode, and the pressure distribution is more uniform. It can achieve full coverage grinding of the wire harness surface and avoid the problem of local insufficient or excessive grinding.

[0028] Surface contact distributes pressure over a larger area, reducing localized pressure on the wire harness surface, lowering the risk of scratches and deformation, and improving the wear resistance and overall quality of the wire harness.

[0029] At the same time, it can also perform high-quality polishing of the wire harness even when the wire harness is running at a high speed;

[0030] 3. In this invention, a cleaning unit is provided, which can control the high-pressure gas generated by the vortex blower to blow off the stubborn abrasives attached to the grinding belt through the combination of centrifugal force and strong airflow. As the speed of the large drive wheel increases, its centrifugal force increases continuously, and correspondingly the airflow intensity ejected from its outlet pipe decreases, maintaining a balance between the combined ability of centrifugal force and airflow intensity to handle abrasives. This ensures the removal of stubborn deposits on the grinding belt while saving energy. Attached Figure Description

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Example: Reference Figure 1-2 The wire harness abrasion device for preventing wear debris accumulation is shown, comprising a first coarse grinding mechanism 1, a second coarse grinding mechanism 2, a first fine grinding mechanism 3, and a second fine grinding mechanism 4 arranged sequentially with identical structures.

[0041] The first coarse grinding mechanism 1 includes mounting plates 101 that are symmetrical about left and right. A large drive wheel 103 and a small rotating wheel 104 are rotatably mounted on both sets of mounting plates 101. The large drive wheel 103 and the small rotating wheel 104 are connected by a grinding belt 108 with abrasive particles on its surface. The large drive wheel 103 is driven by a rotary motor 102 mounted on the mounting plate 101.

[0042] The small rotating wheel 104 is mounted on the slider 106. The slider 106 is slidably connected to the slide block 105 on the mounting plate 101. The side end of the slider 106 is connected to the mounting plate 101 through the connecting spring 107.

[0043] The two sets of large drive wheels 103 on the first coarse grinding mechanism 1 and the first fine grinding mechanism 3 are arranged in a left-right opposite manner;

[0044] The two sets of large drive wheels 103 on the second coarse grinding mechanism 2 and the second fine grinding mechanism 4 are arranged in a vertically opposite manner.

[0045] Coarse grinding particles are provided on the grinding surfaces of the two sets of grinding belts 108 on the first coarse grinding mechanism 1 and the second coarse grinding mechanism 2.

[0046] Fine abrasive particles are provided on the grinding surfaces of the two sets of grinding belts 108 on the first fine grinding mechanism 3 and the second fine grinding mechanism 4.

[0047] The wire harness passes sequentially through the grinding gap formed between the two corresponding sets of grinding belts 108. One end of the wire harness is installed on the pay-off machine, and the other end is installed on the take-up machine.

[0048] It is also equipped with a cleaning unit for cleaning the abrasive shavings adhering to the abrasive belt 108;

[0049] During operation, the two sets of grinding belts 108, which are set opposite to each other, move in the same direction.

[0050] During operation, the wire harness is sequentially passed through the grinding gaps of the first coarse grinding mechanism 1, the second coarse grinding mechanism 2, the first fine grinding mechanism 3, and the second fine grinding mechanism 4. The outer walls of the two sets of grinding belts 108 arranged opposite each other come into contact with the two side walls of the wire harness. The two sets of grinding belts 108, which are arranged left and right and up and down and contain coarse grinding particles, grind the left and right sides and the top and bottom sides of the wire harness (the large drive wheel 103 drives the grinding belts 108 to run through the friction between the large drive wheel and the grinding belts 108). This can achieve comprehensive coarse grinding of the wire harness. The two sets of grinding belts 108, which are arranged left and right and up and down and contain fine grinding particles, grind the left and right sides and the top and bottom sides of the wire harness. This can achieve comprehensive fine grinding of the wire harness. During the grinding process, the grinding debris generated on the grinding surface can be thrown out under the action of the centrifugal force of the rotating grinding belts 108. The grinding debris cannot accumulate at the grinding point, which can achieve good grinding of the wire harness.

[0051] A cleaning unit is provided to remove stubborn abrasive particles adhering to the abrasive belt 108 to improve the polishing quality of subsequent wire harnesses.

[0052] It should be noted that: First, each mounting plate 101 is fixed to the base by mounting feet, and the rotary motors 102 mounted on the mounting plates 101 are electrically connected to the controller; Second, during operation, the two sets of grinding belts 108 arranged opposite each other move in the same direction (the direction of movement of the large drive wheel 103 and the direction of grinding debris ejection are as follows). Figure 5 and Figure 6 As shown), the purpose is to make the two sets of grinding belts 108 set opposite to each other grind the wire harness in opposite directions, so that the friction generated on both sides can cancel each other out, which is conducive to the stable grinding of the wire harness; third, the movable setting of the connecting spring 107 and the small rotating wheel 104 makes it convenient to replace the grinding belt 108.

[0053] As a preferred embodiment of this example, Figure 2 As shown, each set of sliders 106 is equipped with two sets of small rotating wheels 104, which are assembled with the large drive wheel 103 through the grinding belt 108, and a gap is provided between the two small rotating wheels 104.

[0054] When the small rotating wheel 104 is set as a group, its grinding belt 108 forms a line contact with the wire harness for grinding. The contact between the grinding belt and the wire harness is a straight line, and the contact area is small, which can easily lead to uneven distribution of grinding force on the surface of the wire harness, resulting in local under-grinding or over-grinding.

[0055] Due to the limited contact area, the amount of grinding on the wire harness by the grinding belt per unit time is small, resulting in low overall grinding efficiency and requiring a longer processing time. In other words, when the wire harness is in contact, high-quality grinding of the wire harness can only be achieved when the winding speed of the wire harness is low.

[0056] Two sets of small rotating wheels 104 are set up so that the grinding belt 108 corresponding to the two sets of small rotating wheels 104 can perform surface contact grinding on the same part of the wire harness. Compared with line contact grinding, the surface contact method significantly increases the contact area between the grinding belt and the wire harness, and the pressure distribution is more uniform. It can achieve full coverage grinding of the wire harness surface and avoid the problem of local insufficient or excessive grinding.

[0057] Surface contact distributes pressure over a larger area, reducing localized pressure on the wire harness surface, lowering the risk of scratches and deformation, and improving the wear resistance and overall quality of the wire harness.

[0058] At the same time, it can also perform high-quality polishing of the wire harness when the wire harness is running at a high speed.

[0059] As a preferred embodiment of this example, Figure 3 and Figure 4 As shown, the cleaning unit includes an air outlet pipe 6 disposed on the corresponding mounting plate 101 and a hollow pipe 5 installed at the shaft center of one of the large drive wheels 103;

[0060] A centrifugal spring 11 is fixed inside the hollow tube 5, and a movable column 10 is installed at the upper end of the centrifugal spring 11. Multiple sets of second movable rods 13 are circumferentially arranged on the outer wall of the movable column 10, and the ends of the multiple sets of second movable rods 13 away from the movable column 10 are movably connected to the corresponding first movable rods 12. The ends of the multiple sets of first movable rods 12 close to the hollow tube 5 are movably connected to the outer wall of the hollow tube 5.

[0061] A column 14 is fixed at the upper axis of the movable column 10, and a ball bearing 15 is installed at the upper end of the column 14. The upper end of the ball bearing 15 contacts the lower end of the rack 9. The upper end of the rack 9 passes through the plate body installed on the mounting plate 101. A current regulator 7 electrically connected to the vortex blower is provided on the plate body, and a toothed ring 8 that meshes with the rack 9 is installed on the outer wall of the adjustment knob of the current regulator 7. The air outlet of the vortex blower is connected to multiple sets of air outlet pipes 6 through pipes.

[0062] The air outlet direction of the multiple sets of air outlet pipes 6 is opposite to the rotation direction of the corresponding large drive wheel 103;

[0063] Initially, the working power of the vortex blower is at its maximum. As the speed of the large drive wheel 108 decreases, the working power of the vortex blower gradually decreases, and the intensity of the airflow ejected from the outlet pipe 5 decreases.

[0064] The high-pressure gas generated by the controllable vortex blower blows off the stubborn abrasives attached to the grinding belt 108 through the combination of centrifugal force and strong airflow.

[0065] When the large drive wheel 103 accelerates to the set speed, the centrifugal force on the first movable rod 12 increases, and its outer end moves upward continuously. Through the second movable rod 13, the movable column 10 overcomes the gravity of the centrifugal spring 11 and the gear 9 and moves upward. The upward movement of the movable column 10 will drive the gear 9 to move upward. The gear 9 will drive the adjustment knob to rotate through the gear ring 8, thereby reducing the current entering the vortex blower, thus reducing the intensity of the airflow ejected from the exhaust pipe 6.

[0066] As the speed of the large drive wheel 103 increases, its centrifugal force increases continuously, and correspondingly the intensity of the airflow ejected from its exhaust pipe 6 decreases (conversely, as the speed of the large drive wheel 103 decreases, the intensity of its ejected airflow increases), maintaining a balance between the combined ability of centrifugal force and airflow intensity to handle grinding debris, thus ensuring the removal of stubborn deposits on the grinding belt 108 while saving electrical energy.

[0067] As a preferred embodiment of this example, Figure 5 As shown, the wire harness is arranged in a stepped distribution and passes through the grinding gap. This part of the wire harness includes multiple horizontal sections 17 and connecting sections 18 for connecting adjacent horizontal sections 17. Limiting wheels 16 are provided at the corners where the horizontal sections 17 and the connecting sections 18 are connected. The first coarse grinding mechanism 1, the second coarse grinding mechanism 2, the first fine grinding mechanism 3 and the second fine grinding mechanism 4 are sequentially arranged at the positions of the horizontal sections 17 relative to the wire harness.

[0068] The wire harness is arranged in a stepped distribution and passed through the grinding gap, in accordance with the rotation direction of the major drive wheels 108, as follows: Figure 5 and Figure 6 As shown, the ejected grinding debris is thrown out along the tangential direction of the wire bundle, avoiding the debris from splashing into the area of ​​adjacent grinding mechanisms, reducing the accumulation of grinding debris across mechanisms, and ensuring the continuous operation capability of the equipment.

[0069] It should be noted that the stepped structure of the horizontal part 17 and the connecting part 18, together with the limiting wheel 16, forms a natural channel for the discharge of wear debris and also reduces the adhesion of wear debris to the surface of the wire harness.

[0070] As a preferred embodiment of this example, Figure 5 As shown, the connection part 18 of the wire harness is inclined to the horizontal plane.

[0071] The design of the inclined connection part 18 can balance the tension difference between the horizontal transmission section (horizontal part 17) and the inclined section (connection part 18) of the wire harness, preventing wire harness breakage or loosening of the grinding belt due to sudden tension changes. It is especially suitable for high-speed, high-tension wire harness processing scenarios.

[0072] In a preferred embodiment of this invention, the angle θ between the connecting part 18 and the horizontal plane is set to 10° to 30°.

[0073] Within the range of 10°-30°, the bending stress of the wire harness is small, which can effectively suppress high-frequency vibration. Within this range, the vibration amplitude of the wire harness is reduced by about 40%, ensuring grinding accuracy.

[0074] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
