Description

Technical Field

[0001] This utility model relates to the technical field of sub-assembly racks for wire harness production, and in particular to a sub-assembly rack used in wire harness production. Background Technology

[0002] During the wire harness production process, various wire harnesses need to be placed on the assembly rack and fixed on the worktable to facilitate the connection of the wire harnesses and connectors for assembly.

[0003] Existing wire harness production assembly racks, such as the utility model patent disclosed in CN215221227U, disclose an integrated assembly rack for wire harness production, including a workbench. Bidirectional connecting cylinders are fixedly connected to the four corners of the upper surface of the workbench. One connecting cylinder of each bidirectional connecting cylinder is fixedly connected to a horizontal assembly rack support rod, and the other connecting cylinder of each bidirectional connecting cylinder is fixedly connected to a vertical assembly rack support rod. Each vertical assembly rack support rod has a bidirectional connecting cylinder fixedly connected to its upper end. A lower base plate is fixedly connected to the upper surface of the workbench. A mating shaft is movably connected to the upper surface of the lower base plate. The mating shaft is located on one side of the upper surface of the lower base plate, and an auxiliary wire feeding plate is fixedly connected to the upper end of the mating shaft. By using different wire harness lengths, one-way connecting cylinders fixedly connected to different transverse assembly rack support rods can be connected, thereby controlling the tilt angle of the wire harness. This solves the problem of operational difficulties caused by the production of wire harnesses of different specifications. After the wire harness is fixed, the sliding telescopic support rod is moved on the auxiliary slide groove to control the tilt angle of the auxiliary wire feeding plate and fix it in place, thereby improving the production efficiency of the wire harness and the quality of the production support.

[0004] The integrated assembly rack used in wire harness production in the above-mentioned patented technology still has the following drawbacks when in use: When adjusting the angle of the auxiliary wire feeding plate, it is necessary to adjust it by the cooperation of the connecting pin and the connecting pin mating hole. However, the connecting pin mating hole is arranged at a certain interval, which makes the adjustment of the auxiliary wire feeding plate angle discontinuous and easily leads to the situation that the angle of the auxiliary wire feeding plate is not properly placed, resulting in insufficient practicality. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a sub-assembly rack for wire harness production that enables continuous adjustment of the angle of the auxiliary wire feeding plate, avoids the situation of improper placement of the auxiliary wire feeding plate angle, and improves practicality.

[0006] Technical solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a sub-assembly rack for wire harness production, comprising a workbench, auxiliary components, and an adjustment mechanism. A lower base plate is fixedly connected to the top of the workbench. The auxiliary components include an auxiliary wire feeding plate, with rotating shafts fixedly mounted on both sides of the bottom of the auxiliary wire feeding plate. Two sets of bearing seats are symmetrically fixedly connected to the rear side of the top of the lower base plate. The auxiliary wire feeding plate is rotatably mounted on the lower base plate through the cooperation of the rotating shafts and bearing seats. The adjustment mechanism includes a bracket, which is fixedly mounted on the top of the lower base plate and centered horizontally. Two sets of supports are symmetrically fixedly connected to the front end of the bracket. A transmission worm gear is rotatably mounted on the two sets of supports. A handwheel is fixedly sleeved on the right end of the transmission worm gear. A transmission screw is rotatably mounted on the bracket. A worm wheel is fixedly sleeved on the front end of the transmission screw, meshing with the transmission worm gear. A movable seat is screwed onto the transmission screw, slidingly mounted on the bracket. A support rod is rotatably connected to the movable seat. A hinged seat is fixedly mounted on the back of the auxiliary wire feeding plate, and the top of the support rod is hinged to the hinged seat.

[0008] Preferably, a guiding mechanism is provided between the auxiliary wire-laying plate and the top of the lower base plate. The guiding mechanism includes two sets of arc-shaped stop bars, which are symmetrically fixedly connected to the top of the lower base plate. The inner sides of the two sets of arc-shaped stop bars are in contact with the left and right ends of the auxiliary wire-laying plate, respectively. Each set of arc-shaped stop bars is provided with an arc-shaped guide groove centered on the pivot. Two sets of ear plates are symmetrically fixedly connected to the back of the auxiliary wire-laying plate. The outer sides of the two sets of ear plates are aligned with the left and right ends of the auxiliary wire-laying plate, respectively. Guide posts are fixedly connected to the outer sides of the two sets of ear plates, and the two sets of guide posts are slidably installed in the two sets of arc-shaped guide grooves.

[0009] Preferably, a reinforcing rod is fixedly connected between the inner top of the two sets of arc-shaped stop bars and the top of the lower base plate.

[0010] Preferably, the outer wall of the handwheel has multiple sets of anti-slip ridges fixed at equal intervals in a ring.

[0011] Preferably, a limiting groove is provided on the bottom inner side of the bracket, and the movable seat is slidably installed on the bracket by cooperating with the limiting groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, when it is necessary to adjust the angle of the auxiliary pay-off plate, the transmission worm is rotated by turning the handwheel, causing the transmission worm to drive the transmission screw to rotate clockwise through meshing with the worm wheel. The transmission screw then drives the movable seat to slide backward, causing the movable seat to push the auxiliary pay-off plate to rotate clockwise through the hinge between the support rod and the hinge seat. Conversely, when the transmission worm is rotated by turning the handwheel, causing the transmission worm to drive the transmission screw to rotate counterclockwise through meshing with the worm wheel, the transmission screw then drives the movable seat to slide forward, causing the movable seat to pull the auxiliary pay-off plate to rotate counterclockwise through the hinge between the support rod and the hinge seat. This achieves continuous adjustment of the angle of the auxiliary pay-off plate, thus preventing the auxiliary pay-off plate from being improperly positioned and improving its practicality.

[0018] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope. Example

[0019] Please see Figures 1-4This utility model discloses a sub-assembly rack for wire harness production, comprising a workbench 1, an auxiliary wire feeding plate 3, and a support 6. A lower base plate 2 is fixedly connected to the top of the workbench 1. Rotating shafts 4 are fixedly mounted on both sides of the bottom of the auxiliary wire feeding plate 3. Two sets of bearing seats 5 are symmetrically fixedly connected to the rear top of the lower base plate 2. The auxiliary wire feeding plate 3 is rotatably mounted on the lower base plate 2 through the cooperation of the rotating shafts 4 and bearing seats 5. The support 6 is fixedly mounted on the top of the lower base plate 2, and is centered horizontally. Two sets of supports 7 are symmetrically fixedly connected to the front end of the support 6. A transmission worm gear 8 is rotatably mounted on the two sets of supports 7. A handwheel 9 is fixedly sleeved on the right end of the transmission worm gear 8. A transmission screw 10 is rotatably mounted on the support 6. A worm wheel 11 is fixedly sleeved on the front end of the transmission screw 10, meshing with the transmission worm gear 8. A movable seat 12 is screwed onto the transmission screw 10, and the movable seat 12 is slidably mounted on the support 6. A support rod 13 is rotatably connected to the movable seat 12. A support rod 13 is fixedly mounted on the back of the auxiliary wire feeding plate 3. The device includes a hinged seat 14, with the top of the support rod 13 hinged to the hinged seat 14. In use, when the angle of the auxiliary wire-laying plate 3 needs adjustment, the handwheel 9 rotates the transmission worm 8, causing the transmission worm 8 to mesh with the worm wheel 11, driving the transmission screw 10 to rotate clockwise. The transmission screw 10 then drives the movable seat 12 to slide backward, causing the movable seat 12 to push the auxiliary wire-laying plate 3 to rotate clockwise through the hinge between the support rod 13 and the hinged seat 14. Conversely, rotating the handwheel 9 rotates the transmission worm 8, causing the transmission worm 8 to mesh with the worm wheel 11, driving the transmission screw 10 to rotate counterclockwise. The transmission screw 10 then drives the movable seat 12 to slide forward, causing the movable seat 12 to pull the auxiliary wire-laying plate 3 to rotate counterclockwise through the hinge between the support rod 13 and the hinged seat 14. This allows for continuous adjustment of the angle of the auxiliary wire-laying plate 3, preventing improper placement of the auxiliary wire-laying plate 3 and improving its practicality.

[0020] A guiding mechanism is provided between the auxiliary wire-laying plate 3 and the top of the lower base plate 2. The guiding mechanism includes two sets of arc-shaped stop bars 15, which are symmetrically fixedly connected to the top of the lower base plate 2. The inner sides of the two sets of arc-shaped stop bars 15 contact the left and right ends of the auxiliary wire-laying plate 3, respectively. Each set of arc-shaped stop bars 15 is provided with an arc-shaped guide groove 16 centered on the rotating shaft 4. Two sets of ear plates 17 are symmetrically fixedly connected to the back of the auxiliary wire-laying plate 3. The outer sides of the two sets of ear plates 17 contact the left and right ends of the auxiliary wire-laying plate 3, respectively. Alignment is achieved by fixing guide posts 18 to the outer sides of both sets of ear plates 17, with the two sets of guide posts 18 slidably installed in the two sets of arc-shaped guide grooves 16 respectively. When adjusting the angle of the auxiliary wire feeding plate 3, the auxiliary wire feeding plate 3 rotates by driving the guide posts 18 to slide along the arc-shaped guide grooves 16 through the ear plates 17. Through the cooperation of the arc-shaped stop bar 15, the arc-shaped guide grooves 16 and the ear plates 17, the auxiliary wire feeding plate 3 can be effectively prevented from swaying left and right during rotation, making the adjustment of the auxiliary wire feeding plate 3 more stable.

[0021] A reinforcing rod 19 is fixedly connected between the inner top of the two sets of arc-shaped stop bars 15 and the top of the lower base plate 2. By setting the reinforcing rod 19, the arc-shaped stop bars 15 can be effectively supported, the connection between the arc-shaped stop bars 15 and the lower base plate 2 can be strengthened, and the arc-shaped stop bars 15 can be prevented from shaking.

[0022] Multiple sets of anti-slip ridges 20 are fixed in an annular pattern on the outer wall of the handwheel 9; by setting the anti-slip ridges 20, the hand can be prevented from slipping when the hand holds the handwheel 9 to rotate the transmission worm gear 8.

[0023] The bracket 6 has a limiting groove 21 at its inner bottom, and the movable seat 12 is slidably mounted on the bracket 6 by cooperating with the limiting groove 21. By setting the limiting groove 21, the transmission screw 10 can drive the movable seat 12 to move more smoothly and reliably.

[0024] This utility model discloses a sub-assembly rack for wire harness production. Its working principle is as follows: When the angle of the auxiliary wire feeding plate 3 needs to be adjusted, the handwheel 9 rotates the transmission worm 8, causing the transmission worm 8 to drive the transmission screw 10 to rotate clockwise through its engagement with the worm wheel 11. The transmission screw 10 then drives the movable seat 12 to slide backward, causing the movable seat 12 to push the auxiliary wire feeding plate 3 to rotate clockwise through the hinge between the support rod 13 and the hinge seat 14. Conversely, when the handwheel 9 rotates the transmission worm 8, causing the transmission worm 8 to drive the transmission screw 10 to rotate counterclockwise through its engagement with the worm wheel 11, the transmission screw 10 drives the movable seat 12 to slide forward, causing the movable seat 12 to pull the auxiliary wire feeding plate 3 to rotate counterclockwise through the hinge between the support rod 13 and the hinge seat 14. This achieves continuous adjustment of the angle of the auxiliary wire feeding plate 3. Furthermore, the self-locking action of the engagement between the transmission worm 8 and the worm wheel 11 enables... After the angle of the auxiliary wire feeding plate 3 is adjusted, it remains stable and will not move on its own. During the rotation, the auxiliary wire feeding plate 3 drives the guide post 18 to slide along the arc-shaped guide groove 16 through the ear plate 17. The cooperation of the arc-shaped stop bar 15, the arc-shaped guide groove 16 and the ear plate 17 prevents the auxiliary wire feeding plate 3 from swaying left and right during the rotation, thus improving the stability of the auxiliary wire feeding plate 3 during rotation. The workbench 1 and the lower base plate 2 in this utility model are both referenced from an integrated sub-assembly rack for wire harness production with patent publication number CN215221227U, which belongs to the published prior art. The other specific structures and working principles of the workbench 1 and the lower base plate 2 have been described in detail in the published patent. This application only improves the adjustment method of the auxiliary wire feeding plate 3. The other parts have not been changed, so the other parts are not shown in the figure and will not be described in detail here.

[0025] The present invention relates to a sub-packing rack for wire harness production. Its installation method, connection method, or setting method are all common mechanical methods, and any method that can achieve its beneficial effect can be implemented.

[0026] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
