Description

Technical Field

[0001] The present disclosure relates to the technical field of wire harness tooling plates, and particularly to an automotive wire harness tooling plate. Background Art

[0002] With the rapid development of society, people have great demands for vehicle production. In automotive products, there are a large number of requirements for the production of wire harnesses. A wire harness is a wiring component that connects various electrical devices in a circuit and is composed of insulating sheaths, terminal blocks, wires, and insulating wrapping materials, etc.

[0003] During the installation process of the wire harness, the wire harness needs to be placed on the tooling plate. There are multiple points and die bases on the tooling plate. Each point corresponds to a node of the wire harness, and the die base corresponds to the plug of the wire harness. U-shaped insertion rods are correspondingly arranged at the points. The staff places the wire harness on the tooling plate according to the correspondence between the points on the tooling plate and the nodes of the wire harness, fixes it with the U-shaped insertion rods, and judges whether the wire harness meets the standards. After meeting the standards, the staff winds insulating tape around the outer periphery of the wire harness to complete the assembly of the wire harness.

[0004] Chinese Patent CN212587838U disclosed a wire harness tooling plate with strong stability on February 23, 2021, which includes a tooling plate body, U-shaped insertion rods, and a wire harness component. The U-shaped insertion rods are uniformly fixed on the tooling plate body, and the wire harness component is fixed on the U-shaped insertion rods. A clamping component is also fixed on the tooling plate body. The clamping component includes a connecting rod, a universal adjusting ball head, a U-shaped clamping rod, and a wire harness fixing component. One end of the universal adjusting head is connected to the connecting rod. Multiple limiting grooves are formed on the U-shaped clamping rod, and the wire harness fixing component is detachably fixed in the limiting grooves. The wire harness fixing component includes a clamping ring, a clamping seat, an elastic limiting member, and a clamping seat. The clamping seat is fixed at the lower end of the clamping seat. The clamping ring and the clamping seat are hinged to each other through a rotating shaft, and the elastic limiting member is fixed inside the clamping ring. This wire harness tooling plate with strong stability can make the wire harness more convenient during the processing process, and at the same time can avoid the wire harnesses from winding around each other, having the advantages of time-saving, labor-saving, and high processing efficiency.

[0005] Although the above patent makes the wire harness more convenient during the processing process, there are still the following defects:

[0006] Since the U-shaped insertion rods of the above patent are fixed on the tooling plate body, that is, the height of the U-shaped insertion rods cannot be adjusted, and because the distances between some wire harness nodes are relatively close, the distances between the points on the tooling plate and the corresponding U-shaped insertion rods are also relatively close. When the staff winds insulating tape around the outer periphery of the wire harness, it is easily affected by the U-shaped insertion rods and cannot wind the insulating tape tightly along the outer periphery of the wire harness, resulting in poor insulation performance of the wire harness, affecting the subsequent vehicle assembly steps and vehicle safety performance. Utility Model Content

[0007] To solve the problems existing in the above-mentioned prior art, the purpose of the present disclosure is to provide an automotive wiring harness tooling board to avoid the influence of U-shaped insertion rods on workers when winding insulating tapes.

[0008] An automotive wiring harness tooling board described in the present disclosure includes a tooling board body, a plurality of U-shaped insertion rods, and a die base;

[0009] The U-shaped insertion rod includes a U-shaped clamp and an insertion rod.

The insertion rod moves along the thickness direction of the tooling board body;

[0010] The die base is detachably connected to the tooling board body;

[0011] The telescopic locking mechanism includes a locking member, a sleeve, an elastic member, and a guide rod;

The locking member and the insertion rod are rotationally engaged. The sleeve is sleeved outside the locking member and connected to the tooling board body. The inner circumference of the sleeve is provided with a guide rail structure in an array. The guide rail structure includes a first locking groove and a second locking groove. The first locking groove is adapted to the first round teeth, and the second locking groove is adapted to the first round teeth. The length of the first locking groove is less than the length of the second locking groove; The elastic member includes a first connecting portion and a second connecting portion. The first connecting portion is connected to the tooling board body, and the second connecting portion abuts against the guide rod. The elastic member is configured to: make the guide rod always have a tendency to move in the direction of the U-shaped insertion rod; One end of the guide rod away from the second connecting portion abuts against the locking member.

[0013] Preferably, the end surface of the locking member near the insertion rod protrudes in the axial direction of the locking member towards the insertion rod to form the first round teeth.

[0014] Preferably, the outer peripheral surface of the locking member is provided with a plurality of locking ridges arranged at intervals in the circumferential direction of the locking member. The end surface of the locking ridge near the insertion rod protrudes in the axial direction of the locking member towards the insertion rod to form the first round teeth.

[0017] Preferably, scales are provided on the surface of the tooling plate body between two adjacent U-shaped insertion rods.

[0018] The advantages of the automotive wire harness tooling plate described in the present disclosure are as follows:

[0019] Through the setting of the telescopic locking mechanism, the U-shaped insertion rod can be telescoped as needed, that is, the height of the U-shaped insertion rod can be adjusted. When the staff winds the insulating tape around the wire harness, the height of the U-shaped insertion rod can be lowered, so that the staff can wind the insulating tape tightly along the outer circumference of the wire harness, thereby ensuring the insulation performance of the wire harness, not affecting the subsequent vehicle assembly steps, and ensuring the vehicle safety performance.

Detailed Description of the Embodiments

[0025] As Figures 1 to 4 shown, an automotive wire harness tooling plate of the present disclosure includes a tooling plate body 1, a plurality of U-shaped insertion rods 2, and a mold base 3;

[0026] The U-shaped insertion rod 2 includes a U-shaped clip and an insertion rod. One end of the insertion rod is connected to the bottom of the U-shaped clip, and the other end is movably connected to the tooling plate body 1 through a telescopic locking mechanism 4. The insertion rod moves along the thickness direction of the tooling plate body 1;

[0027] The mold base 3 is detachably connected to the tooling plate body 1;

[0028] Specifically, points are correspondingly set on the fixture plate body 1 according to the nodes of the wire harness, and a die base 3 is set according to the plugs of the wire harness. The U-shaped plug rod 2 is arranged at the points, and the die base 3 is detachably connected to the fixture plate body 1. Preferably, the module and the fixture plate body 1 are detachably connected by screws and bolts;

[0029] The U-shaped plug rod 2 is movably connected to the fixture body through a telescopic locking mechanism 4. The U-shaped plug rod 2 moves along the thickness direction of the fixture plate body 1 through the telescopic locking mechanism 4. In an embodiment of the present disclosure, the telescopic locking mechanism 4 includes a locking member 41, a sleeve 42, an elastic member 43, and a guide rod 44;

[0030] One end of the locking member 41 has a number of first round teeth 411, and the cross-section of the first round teeth 411 is a right triangle. The end of the plug rod away from the U-shaped clip has second round teeth adapted to the first round teeth 411. The locking member 41 and the plug rod are rotationally engaged. The sleeve 42 is sleeved outside the locking member 41 and is connected to the fixture plate body 1. A guide rail structure is arranged in a circumferential array on the inner side of the sleeve 42. The guide rail structure includes a first locking groove and a second locking groove. The first locking groove is adapted to the first round teeth 411, and the second locking groove is adapted to the first round teeth 411. The length of the first locking groove is less than the length of the second locking groove; the elastic member 43 includes a first connecting portion and a second connecting portion. The first connecting portion is connected to the fixture plate body 1, and the second connecting portion abuts against the guide rod 44. The elastic member 43 is configured to: make the guide rod 44 always have a tendency to move in the direction of the U-shaped plug rod 2; the end of the guide rod 44 away from the second connecting portion abuts against the locking member 41.

[0031] More specifically, the guide rail structure is formed in the following manner:

[0032] As Figure 2 shown, a first ridge 421 and a second ridge 422 are arranged on the inner side of the sleeve 42. The bottom surfaces of the first ridge 421 and the second ridge 422 are both inclined surfaces, and the angle of the inclined surface is adapted to the first round teeth 411. The first ridge 421 is arranged in a circumferential array, and a second ridge 422 is abutted on one side of each first ridge 421. A first locking groove is formed on the abutting side of the first ridge 421 and the second ridge 422, and a second locking groove is formed on the other side of each first ridge 421.

[0033] Since the length of the first locking groove is less than the length of the second locking groove, when the locking member 41 enters the first locking groove, the telescopic locking mechanism 4 is in a contracted state, and the height of the U-shaped plug rod 2 decreases; when the locking member 41 enters the second locking groove, the telescopic locking mechanism 4 is in an extended state, and the U-shaped plug rod 2 returns to its initial height.

[0034] When the U-shaped insertion rod 2 is pressed down once, the telescopic locking mechanism 4 can be contracted or extended, and then the U-shaped insertion rod 2 can be in a state with a lower height or the original height.

[0035] Through the setting of the telescopic locking mechanism 4, the U-shaped insertion rod 2 can be telescoped as needed, that is, the height of the U-shaped insertion rod 2 can be adjusted. When the staff winds the insulating tape around the outer periphery of the wire harness, the height of the U-shaped insertion rod 2 can be lowered, so that the staff can wind the insulating tape tightly along the outer periphery of the wire harness, thereby ensuring the insulation performance of the wire harness, not affecting the subsequent vehicle assembly steps and ensuring the vehicle safety performance.

[0036] Furthermore, there are the following two embodiments for the first round of teeth 411:

[0037] Embodiment 1

[0038] On the end surface of the locking member 41 close to the insertion rod, a first round of teeth 411 are formed by protruding in the direction close to the insertion rod along the axial direction of the locking member 41.

[0039] Specifically, the locking member 41 is a hollow cylinder, that is, the end surface of the locking member 41 is annular. On the end surface of the locking member 41 close to the insertion rod, a first round of teeth 411 are formed by protruding in the direction close to the insertion rod along the axial direction of the locking member 41, and several first round of teeth 411 are arranged in a circumferential array along the circumference of the locking member 41.

[0040] On one end of the insertion rod close to the locking member 41, a second round of teeth adapted to the first round of teeth 411 are formed, and the locking member 41 and the insertion rod are rotationally engaged. Specifically, the locking member 41 and the insertion rod are rotationally engaged through the first round of teeth 411 and the second round of teeth; when the U-shaped insertion rod 2 is in the state of the original height, the staff presses down the U-shaped insertion rod 2, the insertion rod presses down the locking member 41, and under the reaction force of the elastic member 43, the locking member 41 rotates into the first locking groove in the sleeve 42, and at this time the telescopic locking mechanism 4 is in a contracted state, and the height of the U-shaped insertion rod 2 is reduced. When the U-shaped insertion rod 2 is pressed again in the above situation, the U-shaped insertion rod 2 rotates into the second locking groove under the reaction force of the elastic member 43, and at this time the telescopic locking mechanism 4 is in an extended state, and the U-shaped insertion rod 2 returns to the original height.

[0041] Embodiment 2

[0042] On the outer peripheral surface of the locking member 41, a number of locking ridges are arranged at intervals along the circumferential direction of the locking member 41, and on the end surface of the locking ridge close to the insertion rod, a first round of teeth 411 are formed by protruding in the direction close to the insertion rod along the axial direction of the locking member 41.

[0043] Specifically, the locking member 41 is a hollow cylinder, that is, the end face of the locking member 41 is annular. A plurality of locking ridges are arranged at intervals along the circumferential direction of the locking member 41 on the outer peripheral surface of the locking member 41. The surface of the end of the locking ridge close to the insertion rod bulges towards the insertion rod along the axial direction of the locking member 41 to form a first set of teeth 411.

[0044] One end of the insertion rod close to the locking member 41 is formed with a second set of teeth adapted to the first set of teeth 411. The locking member 41 and the insertion rod are rotationally engaged. Specifically, the locking member 41 and the insertion rod are rotationally engaged through the first set of teeth 411 and the second set of teeth. When the U-shaped insertion rod 2 is at the original height, the staff presses down the U-shaped insertion rod 2, and the insertion rod presses down the locking member 41. Under the reaction force of the elastic member 43, the locking member 41 rotates into the first locking groove in the sleeve 42. At this time, the telescopic locking mechanism 4 is in a contracted state, and the height of the U-shaped insertion rod 2 decreases. When the U-shaped insertion rod 2 is pressed again in the above situation, the U-shaped insertion rod 2 rotates into the second locking groove under the reaction force of the elastic member 43. At this time, the telescopic locking mechanism 4 is in an extended state, and the U-shaped insertion rod 2 returns to the original height.

[0045] For the above implementation manner of the first set of teeth 411, the staff can select according to the actual situation.

[0046] Further, there are the following two embodiments of the elastic member 43:

[0047] Embodiment 1

[0048] As Figure 3 shown, the elastic member 43 is a spring. One end of the spring is a first connection portion, and the other end is a second connection portion. The tooling plate body 1 is a hollow cuboid structure. The telescopic locking mechanism 4 is arranged inside the tooling plate body 1. The first connection portion is connected to the inner side of the bottom surface of the tooling plate body 1, and the second connection portion abuts against the guide rod 44.

[0049] Specifically, the tooling plate body 1 is a hollow cuboid structure, that is, the internal space of the tooling plate body 1 is relatively large. The telescopic locking mechanism 4 is arranged inside the tooling plate body 1. The elastic member 43 is selected as a spring. The spring is selected according to the diameter of the guide rod 44 in the telescopic locking mechanism 4. In this embodiment, one end of the spring is a first connection portion, and the other end is a second connection portion. The first connection portion is connected to the inner side of the bottom surface of the tooling plate body 1, preferably fixedly connected, and can be bonded with an adhesive. The second connection portion abuts against the guide rod 44. When the U-shaped insertion rod 2 is compressed downward, the locking member 41 moves downward, and the first set of teeth 411 moves along the axial direction of the sleeve 42. When moving downward to the end of the first set of teeth 411 and the end of the first locking groove or the end of the second locking groove, under the reaction force of the elastic member 43, it enters the first locking groove or the second locking groove, so that the telescopic locking mechanism 4 is in a contracted or extended state, thereby realizing the adjustment of the height of the U-shaped insertion rod 2.

[0050] Example 2

[0051] As Figure 4 shown, the elastic member 43 is an elastic band. Both ends of the elastic band are the first connecting portions, and the middle portion of the elastic band is the second connecting portion. A through hole adapted to the guide rod 44 is formed at the bottom of the tooling plate body 1 corresponding to the telescopic locking mechanism 4. The first connecting portion is connected to the outer side of the bottom surface of the tooling plate body 1, and the second connecting portion abuts against the guide rod 44.

[0052] Specifically, in this embodiment, the elastic member 43 is selected as an elastic band. The width of the elastic band is selected according to the diameter of the guide rod 44. Both end portions of the elastic band are the first connecting portions, and the middle portion of the elastic band is the second connecting portion. A through hole adapted to the guide rod 44 is formed at the bottom of the tooling plate body 1 corresponding to the telescopic locking mechanism 4. The first connecting portion is connected to the outer side of the bottom surface of the tooling plate body 1, preferably fixedly connected. It can be bonded with an adhesive or the end portion of the elastic band can be connected to the bottom surface of the tooling plate body 1 by nails such as iron nails. The second connecting portion abuts against the guide rod 44. When the U-shaped plug 2 is compressed downward, the locking member 41 moves downward, and the first gear teeth 411 move axially along the sleeve 42, so that the guide rod 44 passes through the through hole and compresses the elastic member 43 downward. When moving downward to the end portion of the first gear teeth 411 and the end portion of the first locking groove or the end portion of the second locking groove, under the reaction force of the elastic member 43, it enters the first locking groove or the second locking groove, so that the telescopic locking mechanism 4 is in a contracted or extended state, thereby realizing the adjustment of the height of the U-shaped plug 2.

[0053] For the above implementation manner of the elastic member 43, the staff can select according to the actual situation.

[0054] Further, in order to enable the staff to more intuitively judge whether the wire harness meets the specifications and standards, scales are provided on the surface of the tooling plate body 1 between two adjacent U-shaped plugs 2.

[0055] For a wire harness tooling plate described in the present disclosure, through the setting of the telescopic locking mechanism 4, the U-shaped plug 2 can be telescoped as needed, that is, the height of the U-shaped plug 2 can be adjusted, so that when the staff winds the insulating tape around the outer periphery of the wire harness, the height of the U-shaped plug 2 can be lowered, so that the staff can wind the insulating tape tightly along the outer periphery of the wire harness, that is, the present disclosure can, thereby ensuring the insulation performance of the wire harness, not affecting the subsequent vehicle assembly steps and ensuring the vehicle safety performance.
