Abstract
Description
Technical Field
[0001] This utility model relates to the field of assembly inspection tools, and in particular to an inspection tool for an automobile engine compartment cover assembly. Background Technology
[0002] With the continuous development of society and the continuous progress of technology, the technology related to assembly inspection tools is also constantly improving. In the mechanical equipment manufacturing process, the processing of automobile engine compartment cover assemblies is very difficult and requires extremely high precision. Otherwise, they cannot be installed on the equipment. Therefore, it is necessary to use inspection tools to inspect the processed products.
[0003] Patent document with announcement number "CN218864935U" discloses an inspection tool for an automobile engine compartment cover assembly, including a workbench. The upper front part of the workbench is provided with a second bracket and a cross plate from left to right, and the upper left part of the workbench is provided with a first bracket.
[0004] Although the aforementioned patent documents have solved the problems of cumbersome operation process and inconvenience for operators in installation, disassembly and debugging, the following drawbacks still exist: before using the crane to hook the ring to move the assembly fixture, it is necessary to manually screw multiple screws into the workbench for installation, which is cumbersome and inconvenient, and it is not convenient to quickly move the assembly fixture using the crane. Utility Model Content
[0005] The purpose of this utility model is to solve the following shortcomings in the prior art: before using a crane to hook the ring and move the assembly fixture, it is necessary to manually screw multiple screws into the workbench for installation, which is cumbersome and inconvenient, and it is not convenient to quickly move the assembly fixture using a crane. Therefore, this utility model proposes an automotive engine compartment cover assembly fixture.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A vehicle engine compartment cover assembly inspection fixture includes a workbench with two slots, each slot having a rotating shaft rotatably connected thereto, and each rotating shaft having two lifting rings fixedly connected thereto. A groove is provided on one side of the workbench, and a circular plate is fixedly connected to one end of each rotating shaft.
[0008] Two rectangular plates are fixedly connected within the groove, and a bidirectional lead screw is rotatably connected to the two rectangular plates. Two sliders are slidably connected within the groove, and each slider is threadedly connected to the bidirectional lead screw. Each slider is provided with a moving component, which includes a hinge rod hinged to the slider. A round rod is fixedly connected to each round plate, and each hinge rod is rotatably connected to the corresponding round rod. A sliding component is provided on the worktable.
[0009] Preferably, the sliding assembly includes a movable block slidably mounted on the worktable, and a baffle is fixedly connected to the movable block.
[0010] Preferably, the workbench is provided with a T-shaped groove for the moving block to move up and down, and the cross-section of the moving block is I-shaped.
[0011] Preferably, a spring is fixedly connected to the lower inner wall of the T-shaped groove, and the spring and the moving block are fixedly connected.
[0012] Preferably, a limiting rod is fixedly connected to the movable block, and the T-slot and the groove are in communication.
[0013] Preferably, a rotating wheel is fixedly connected to the bidirectional lead screw, and the rotating wheel has multiple slots for connecting the limiting rod.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] Initially, all lifting rings are fully retracted into their corresponding slots. When the worktable needs to be lifted using a crane, first push the baffle downwards. After the limit rod moves, it will disengage from the slot. Then, manually rotate the rotating wheel. The double-acting screw and the rectangular plate will rotate relative to each other. The two sliders will move along the double-acting screw, increasing the distance between them. The tilt angles of each hinge rod will change simultaneously, causing each round rod and the round plate to rotate. The two rotating shafts will rotate relative to the worktable. After rotating, each lifting ring will move to the outside of the slot, allowing for quick installation of multiple lifting rings. The operation is convenient and fast, facilitating the rapid movement of the assembly fixture using a crane. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.
[0023] Reference Figures 1-4 A vehicle engine hood assembly inspection fixture includes a workbench 1. Two slots 6 are formed in the workbench 1, and a rotating shaft 7 is rotatably connected to each slot 6. Two lifting rings 2 are fixedly connected to each rotating shaft 7. A groove 9 is formed on one side of the workbench 1. A circular plate 10 is fixedly connected to one end of each rotating shaft 7. Two rectangular plates 14 are fixedly connected to the groove 9, and a bidirectional lead screw 13 is rotatably connected to the two rectangular plates 14. Two sliders 12 are slidably connected to the groove 9, and each slider 12 is threadedly connected to the bidirectional lead screw 13. Each slider 12 is provided with a moving assembly, which includes a hinge rod 11 hinged to the slider 12. A round rod 17 is fixedly connected to each circular plate 10, and each hinge rod 11 is rotatably connected to the corresponding round rod 17. The workbench 1 is provided with a sliding assembly.
[0024] The sliding assembly includes a movable block 4 slidably mounted on the worktable 1. A baffle 5 is fixedly connected to the movable block 4. A T-shaped groove 8 for the movable block 4 to move up and down is provided on the worktable 1. The movable block 4 has an I-shaped cross-section. A spring 3 is fixedly connected to the lower inner wall of the T-shaped groove 8. The spring 3 and the movable block 4 are fixedly connected. A limit rod 16 is fixedly connected to the movable block 4. The T-shaped groove 8 and the groove 9 are connected. A rotating wheel 15 is fixedly connected to the bidirectional lead screw 13. The rotating wheel 15 has multiple slots for connecting the limit rod 16. In the initial state, the movable block 4 is located in the upper middle part of the T-shaped groove 8 under the elastic force of the spring 3. At this time, the baffle 5 is in close contact with the surface of the worktable 1 and completely covers the groove 9 to prevent the rotating wheel 15 from being touched at will. The upper end of the limit rod 16 is inserted into the corresponding slot, which can effectively prevent the rotating wheel 15 from rotating. This can prevent the bidirectional lead screw 13 from rotating relative to the rectangular plate 14 at will.
[0025] In this invention, in the initial state, all the lifting rings 2 are completely housed inside the corresponding slots 6. When the workbench 1 needs to be lifted by a crane, the baffle 5 is pushed down first. After the baffle 5 moves, it will be misaligned with the groove 9. After the limit rod 16 moves, it will disengage from the slot. Then, the rotating wheel 15 is manually rotated. The double-acting screw 13 rotates relative to the rectangular plate 14. The two sliders 12 move along the double-acting screw 13 and slide relative to the groove 9. The distance between the two sliders 12 increases. The tilt angle of each hinge rod 11 changes simultaneously. Each round rod 17 and the round plate 10 rotate simultaneously. The two rotating shafts 7 rotate relative to the workbench 1. After each lifting ring 2 rotates, it will move to the outside of the slot 6. Multiple lifting rings 2 can be quickly installed. The operation is convenient and quick, and it is convenient to move the assembly fixture quickly using a crane.
