Description

Technical Field

[0001] The utility model relates to the technical field of automobile part processing, and particularly relates to a positioning device for processing an automobile side cover. Background Technique

[0002] The automobile side cover is an important part of the automobile body or cab, covering the irregular surfaces and interiors of the engine and chassis. It is both an appearance decorative part and a closed shell-shaped stress-bearing part. The position of the side cover can include the engine hood, which is a component covering the engine compartment of the automobile and is usually also called the bonnet or engine cover. During the processing of the automobile side cover, a positioning device is needed to position and fix it.

[0003] As disclosed in a Chinese patent: A processing platform for aluminum alloy automobile parts, application number: CN202321962427.0, includes a workbench. A driving component and an adjusting component are arranged under the workbench. The driving component is connected to the adjusting component. Four movable components are arranged on the adjusting component, and all four movable components are arranged inside the workbench. In this utility model, the driving component of the workbench drives the four movable components to approach each other through the adjusting component and then contact the automobile parts to be processed. The four movable components approaching each other can deform according to the shape of the automobile parts to be processed. The four deformed movable components can position and fix the automobile parts to be processed with different shapes. This platform can position and firmly fix the automobile parts to be processed with different shapes on the support frame without replacing the internal positioning structure, and the operation is simple.

[0004] However, in the above technical solution, when fixing an object, the spring inside the movable component is used to squeeze and fix the object. Since the sizes and shapes of the objects are different, the spring forces in different parts will also be different. When processing the object, the processing equipment will inevitably exert a certain force on the object. Under the condition of the spring force difference and the external force exerted by the processing equipment, the object is likely to move to the side with smaller spring force, resulting in accidental movement of the object during the processing and causing quality problems in the processing. Content of the Utility Model

[0005] The main purpose of the utility model is to provide a positioning device for processing an automobile side cover, which can effectively solve the problem in the background technique that when fixing an object, the spring inside the movable component is used to squeeze and fix the object. Since the sizes and shapes of the objects are different, the spring forces in different parts will also be different. When processing the object, the processing equipment will inevitably exert a certain force on the object. Under the condition of the spring force difference and the external force exerted by the processing equipment, the object is likely to move to the side with smaller spring force, resulting in accidental movement of the object during the processing and causing quality problems in the processing.

Specific embodiments

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] As Figure 1 and Figure 2 shown, a positioning device for machining the side cover of an automobile includes a device main body 1. A plurality of movable plates 2 are arranged on the device main body 1. A slide bar 3 is slidably arranged on the movable plate 2. One end of the slide bar 3 is fixedly provided with a protective pad 4. The end of the slide bar 3 far from the protective pad 4 is fixedly provided with a stop block 5. A first spring 6 is fixedly arranged on the side of the stop block 5 close to the movable plate 2. A tooth groove 7 is arranged on one side of the slide bar 3. A plurality of locking mechanisms 8 are arranged on one side above the movable plate 2. A first gear 9 is arranged on the locking mechanism 8. A rack 10 is slidably arranged on one side of the movable plate 2. One end of the rack 10 is fixedly provided with a push-pull plate 11.

[0021] As Figure 3 shown, in another embodiment of the present utility model, the locking mechanism 8 includes a mechanism base 801. A rotation groove 802 is arranged on the mechanism base 801. A second gear 803 is rotatably arranged in the rotation groove 802. A first chute 804 is arranged on one side above the rotation groove 802. A gear claw 805 is slidably arranged in the first chute 804;

[0022] A second chute 806 is provided on the gear claw 805. A pressure post 807 is slidably arranged in the second chute 806. A second spring 808 is fixedly arranged on one inner wall of the second chute 806. A threaded hole 809 is provided on one side above the first chute 804. A threaded post 8010 is arranged in the threaded hole 809. When the slide bar 3 moves, the slide bar 3 drives the second gear 803 to rotate through the tooth groove 7. The second gear 803 presses the gear claw 805, causing the gear claw 805 to move towards the threaded post 8010, and the second spring 808 deforms. When the second gear 803 no longer presses the gear claw 805, the second spring 808 rebounds, causing the gear claw 805 to be repositioned between the two teeth of the second gear 803, facilitating locking. When it is necessary to lock the position of the slide bar 3, first, the first gear 9 is rotated through the rack 10. The first gear 9 drives the threaded post 8010 to rotate. Then, the threaded post 8010 is moved towards the second gear 803 through the threaded hole 809. The threaded post 8010 drives the pressure post 807 to move, causing the pressure post 807 to completely enter the second chute 806, thereby fixing the position of the gear claw 805. At this time, the gear claw 805 can no longer move, so the second gear 803 is fixed by the gear claw 805, and then the position of the slide bar 3 is fixed through the second gear 803 and the tooth groove 7, thereby locking the position of the slide bar 3 and preventing the slide bar 3 from accidentally moving.

[0023] The working principle of the positioning device for automobile side cover processing:

[0024] During use, first place the object on the device main body 1, and then move the movable plate 2 closer to the object.

[0025] When the protective pad 4 contacts the object, the protective pad 4 drives the slide bar 3 to slide different distances in the movable plate 2 according to the shape of the object. The first spring 6 elongates. The elongated first spring 6 fixes the object through the slide bar 3 and the protective pad 4. Then, press the push-pull plate 11. The push-pull plate 11 drives the rack 10 to move. The rack 10 drives the first gear 9 to rotate. The first gear 9 drives the threaded post 8010 to rotate. Then, the threaded post 8010 is moved towards the second gear 803 through the threaded hole 809. The threaded post 8010 drives the pressure post 807 to move, causing the pressure post 807 to completely enter the second chute 806, fixing the position of the gear claw 805. At this time, the gear claw 805 can no longer move. The second gear 803 is fixed by the gear claw 805, and then the position of the slide bar 3 is fixed through the second gear 803 and the tooth groove 7, locking the position of the slide bar 3 and preventing the slide bar 3 from accidentally moving, thereby locking the position of the object and preventing the object from accidentally moving during the processing.

[0026] Obviously, the above embodiments of the present utility are merely examples for clearly illustrating the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or alterations can be made based on the above description. It is impossible to list all the implementation manners here. Any obvious changes or alterations derived from the technical solutions of the present invention still fall within the protection scope of the present invention.
