Description

Technical Field

[0001] This utility model relates to the field of tailgate hinge processing technology, and in particular to a tailgate hinge processing tooling. Background Technology

[0002] Tailgate hinge machining fixtures are specialized tools or equipment used in the production, manufacturing, and processing of automotive tailgate hinges. These fixtures ensure the precision, efficiency, and consistency of hinge parts during the machining process.

[0003] In the existing technology, some tailgate hinge processing fixtures first require precise positioning of the blank part. By designing specific positioning pins, positioning grooves, or V-blocks, the hinge parts are fixed in the correct position. However, some tailgate hinge processing fixtures use fixing methods such as bolt fixing after positioning, which require a long time for installation and disassembly, resulting in the time required for tailgate hinge processing and affecting the overall work efficiency.

[0010] As a further description of the above technical solution:

[0011] The C-shaped sliding plate has a first drilling groove on its exterior, and the fixing mechanism base plate has a second drilling groove on its interior, for positioning the drilling position.

[0012] As a further description of the above technical solution:

[0013] The fixed mechanism base plate has two side plates fixedly connected to its exterior. The inner side of the two side plates is fixedly connected to a placement plate. The bottom of the placement plate is fixedly connected to the exterior of the fixed mechanism base plate. The top of the side plate has a slotted hole. The inner wall of the slotted hole is provided with a locking block. The top of the placement plate is used to place the tail hinge body.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, starting the motor drives the rotating shaft to rotate, causing the bidirectional threaded rod to rotate as well, thereby causing the moving plates to move towards each other, driving the C-shaped sliding plate to slide in the slide rail, so that the inner side of the C-shaped sliding plate locks the tail hinge body, achieving the effect of fixing the tail hinge body, making it convenient to remove the tail hinge body later. At the same time, the drilling slot two is used to locate the position to be drilled, thereby improving work efficiency.

[0022] 2. In this utility model, when the bidirectional threaded rod rotates, it drives the gear to rotate, which in turn drives the sliding plate to slide along the sliding groove, thereby driving the connecting slider to slide and moving the receiving plate. This causes the pressure plate to press against one side of the tail hinge body and continue to press down, causing the damper to deform, thus achieving the effect of fixing and preventing the tail hinge body from moving and causing drilling errors.

[0033] Reference Figures 3 to 5 The outer sides of the slide plate 4 and the fixing mechanism base plate 2 are provided with slide groove 14. The inner wall of slide groove 14 is slidably connected with slide tooth plate 15. The inner side of slide plate 4 is provided with slide groove 26. One end of slide tooth plate 15 is fixedly connected with connecting slider 17, and the outer side of connecting slider 17 is slidably connected to the inner wall of slide groove 26 to drive connecting slider 17 to slide. One side of connecting slider 17 is fixedly connected with receiving plate 18. The bottom of receiving plate 18 is fixedly connected with damper 19. One end of damper 19 is fixedly connected with pressure plate 20 to fix tail hinge body 1. The outer side of C-shaped slide plate 12 is provided with drilling groove 21. The outer surface of fixing mechanism base plate 2 is provided with drilling groove 22 to locate the drilling position.

[0034] Reference Figure 1 , Figure 2 and Figure 6 The fixed mechanism base plate 2 has two side plates 23 fixedly connected to its exterior. The inner side of the two side plates 23 is fixedly connected to a placement plate 24. The bottom of the placement plate 24 is fixedly connected to the exterior of the fixed mechanism base plate 2. The top of the side plate 23 has a slotted hole 25. The inner wall of the slotted hole 25 is provided with a locking block 29 for placing the tail hinge body 1. The side plate 23 is fixedly connected to its exterior with a fixed plate 26. The fixed plate 26 is rotatably connected to a rotating shaft 27. The rotating shaft 27 is fixedly connected to its exterior with a locking rod 28 for restricting the tail hinge body 1. The tail hinge body 1 is placed on the top of the placement plate 24.

[0035] Working principle: When the produced tail hinge body 1 needs to be drilled, place the tail hinge body 1 on the top of the placement plate 24 to make it fit, and rotate the rotating shaft 27 on the fixed plate 26. Hold the locking rod 28 and rotate it through the rotating shaft 27 so that the locking rod 28 is in the slotted hole 25 above the tail hinge body 1. Insert the locking block 29 into the slotted hole 25 to lock it in place, fix the locking rod 28, limit the tail hinge body 1, and perform initial fixation.

[0036] The starter motor 5 drives the rotating shaft 6 to rotate, causing the bidirectional threaded rod 7 to rotate. This causes the two moving plates 8 to move along the bidirectional threaded rod 7. When the moving plates 8 move, they cause the limiting plate 13 to move, which in turn causes the C-shaped sliding plate 12 connected to the limiting plate 13 to slide inside the slide rail 11. The C-shaped sliding plate 12 then locks onto both ends of the hinge base plate 102 and contacts one side of the tail hinge body 1, aligning the second drilling slot 22 with the first drilling slot 21. At the same time, when the bidirectional threaded rod 7 rotates, it drives the gear 9 to rotate, causing the sliding tooth plate 15 to slide within the first sliding groove 14. When the first sliding groove 14 moves, it causes the connecting slider 17 to slide within the second sliding groove 16, which in turn causes the receiving plate 18 to move, allowing the pressure plate 20 to contact the tail hinge body 1 and simultaneously press the damper 19 until the C-shaped sliding plate 12 locks onto the tail hinge body 1 and the pressure plate 20 presses against the tail hinge body 1. Then, the plate 20 is aligned with the second drilling slot 22 for drilling.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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.
