Description

Technical Field

[0001] This utility model relates to the field of automotive technology, and in particular to a split-type HDE front-end module opening inspection tool. Background Technology

[0002] The modular design means that it is not a single module, but rather composed of multiple relatively independent parts, including radiator brackets, condenser brackets, and anti-collision beams. These parts are combined together by means of bolts, clips, etc., and each part has its specific function.

[0003] An opening gauge is a tool used to inspect the opening-related parameters and performance of a split-type HDE front-end module. The opening gauge can accurately measure and evaluate the opening size, shape, and positional accuracy of the split-type HDE front-end module to determine whether it meets the design requirements and relevant standards.

[0004] Traditional measurement opening fixtures are designed based on the design requirements of the parts, without fully considering the positioning methods of each point on the parts. Existing technology adopts a front-end module structure, which integrates the front bumper mounting point, headlight mounting point, front cover mounting point, and buffer pad mounting. The structure of the front-end module opening fixture needs to be improved to adapt to the accuracy measurement requirements of each mounting point. However, for different models or series of split HDE front-end modules, due to the significant differences in the size, shape, and position of their openings, one type of opening fixture cannot be fully applicable to the inspection of all models of modules. Fixtures need to be designed and manufactured separately for different models, which increases costs and management difficulty. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a split-type HDE front-end module opening fixture, which aims to improve the problem that the design and manufacture of fixtures for different models in the prior art increases costs and management difficulties.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a split-type HDE front-end module opening inspection fixture, comprising a base, a worktable on the top of the base, a rotating shaft I fixedly connected to the middle of the top wall of the worktable, a connecting plate rotatably connected to the outer wall of the rotating shaft I, rotating shaft II fixedly connected to the front and rear sides of the top wall of the connecting plate, connecting blocks rotatably connected to the outer walls of the two rotating shaft II, rotating shaft III rotatably connected to the outer walls of the two connecting blocks, slide rails fixedly connected to the front and rear sides of the top wall of the worktable, sliders slidably connected to the outer walls of the two slide rails, rotating shaft III fixedly connected to the middle of the bottom wall of the slider, centering frames fixedly connected to the top walls of the two sliders, a hydraulic rod fixedly connected to the right side of the left slider, the hydraulic rod fixedly connected to the rear side of the top wall of the worktable, and a lifting mechanism installed at the bottom of the worktable for lifting the worktable.

[0007] As a further description of the above technical solution:

[0008] The lifting mechanism includes a motor, which is fixedly connected to the front side of the middle of the top wall of the base. The output end of the motor is fixedly connected to a connecting shaft. A support cylinder is fixedly connected to the front side of the middle of the top wall of the base. The connecting shaft is rotatably connected to the lower middle part of the rear side of the outer wall of the support cylinder. A bevel gear one is fixedly connected to the front side of the outer wall of the connecting shaft. A bevel gear two is meshed with the front side of the outer wall of the bevel gear one. A rotating shaft four is fixedly connected to the bottom wall of the bevel gear two. The rotating shaft four is rotatably connected to the middle of the inner bottom wall of the support cylinder. A threaded rod is fixedly connected to the top wall of the bevel gear two. A threaded cylinder is threadedly connected to the outer wall of the threaded rod. Guide blocks are fixedly connected to the front and rear sides of the outer wall of the threaded cylinder. Guide grooves are opened on the front and rear sides of the inner wall of the support cylinder. The guide grooves are slidably connected to the guide blocks.

[0009] As a further description of the above technical solution:

[0010] The centering frame has detection references installed on the left and right sides of its top wall and the front side of its top wall.

[0011] As a further description of the above technical solution:

[0012] Positioning blocks are installed on both the left and right sides of the outer wall of the centering frame.

[0013] As a further description of the above technical solution:

[0014] Both of the centering frames are equipped with position determining blocks on the front side of their outer walls, and position determining seats are installed in the middle of the front side of the outer walls of the position determining blocks.

[0015] As a further description of the above technical solution:

[0016] A positioning frame is fixedly connected to the front side of the top wall of the base.

[0017] As a further description of the above technical solution:

[0018] The base has multiple positioning holes equidistantly spaced on its top wall, and positioning pins are installed inside the positioning holes, which engage with the positioning holes.

[0019] As a further description of the above technical solution:

[0020] The base is equipped with casters at all four corners of its bottom wall.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the left centering frame is pushed by a hydraulic rod, causing the slider under the left centering frame to move outward on the slide rail. The rotating shaft three under the slider stretches the connecting block, and the connecting block rotates on the rotating shaft two of the connecting plate, causing the connecting plate to rotate on the rotating shaft one. The rotation of the connecting plate drives the connecting block on the right side to stretch at the same time, causing the centering frame to move outward simultaneously. By moving the centering frame simultaneously, it can adapt to the detection of different models of front-end modules, reducing costs and management difficulties.

[0023] 2. In this utility model, the first bevel gear on the front side of the motor drive shaft rotates, the first bevel gear drives the second bevel gear on the front side to rotate, the second bevel gear drives the threaded rod to rotate, and the threaded rod should drive the threaded cylinder to rotate. Since there are guide blocks on the front and rear sides of the threaded cylinder, and the guide blocks slide in the guide groove, the threaded cylinder rises and falls under the action of the guide blocks. The height of the worktable can be precisely adjusted according to actual needs by raising and lowering the threaded cylinder. Attached Figure Description

The rotating shaft 3 8 under the slider 9 stretches the connecting block 7. The connecting block 7 rotates on the rotating shaft 2 6 of the connecting plate 5, so that the connecting plate 5 rotates on the rotating shaft 1 4. The rotation of the connecting plate 5 drives the right connecting block 7 to stretch at the same time, so that the centering frame 11 moves outward at the same time. The simultaneous movement of the centering frame 11 can adapt to the detection of different types of front-end modules.

[0039] The motor 201 drives the bevel gear 204 on the front side of the connecting shaft 202 to rotate. The bevel gear 204 drives the bevel gear 205 on the front side to rotate. The bevel gear 205 drives the threaded rod 207 to rotate. The threaded rod 207 drives the threaded cylinder 208 to rotate. Since there are guide blocks 209 on the front and rear sides of the threaded cylinder 208, and the guide blocks 209 slide in the guide groove 210, the threaded cylinder 208 rises and falls under the action of the guide blocks 209.
