Description

Technical Field

[0001] The utility model relates to the technical field of processing fixtures for rear brackets of cameras, and particularly relates to a processing fixture for a rear bracket of a camera. Background Art

[0002] At present, in-vehicle cameras, as the core perception devices of automobiles, have been widely used in the automotive industry due to their deep historical accumulation and low-cost advantages. In autonomous driving vehicles, in-vehicle cameras mainly serve as the main means of collecting information and analyzing images, and can realize a series of functions such as vehicle recognition, pedestrian recognition, and lane line recognition. The rear camera plays a quite important role during driving, reversing, and autonomous driving. The rear camera bracket is one of the main components of the rear camera.

[0003] Since the rear bracket of the rear camera is manufactured by die-casting process, it is impossible to form process holes in the same direction as the support surface during the manufacturing process. There will also be some changes in the rear brackets of rear cameras of different vehicles, and the sizes of the process holes will change. This results in the situation that when using a unified processing fixture to process and position the rear bracket of the rear camera, some rear camera brackets will shake and cannot be effectively positioned. Therefore, it is necessary to design a processing fixture for the rear bracket of the camera that can effectively fix most rear camera brackets. Content of the Utility Model

[0004] To solve the technical problem that some rear camera brackets with different models cannot be effectively fixed when using a processing fixture, the utility model provides a processing fixture for a rear bracket of a camera.

[0005] The utility model is realized by adopting the following technical solutions: A processing fixture for a rear bracket of a camera, including a bottom plate. One side of the bottom plate is provided with a part. A plurality of positioning components for positioning the part are fixedly installed on one side of the bottom plate. A plurality of first fixing components for cooperating with the positioning components to fix the part are arranged on the top of the bottom plate. A second fixing component for assisting in fixing the part is arranged at the bottom of the part. A plurality of first bases are fixedly installed on one side of the bottom plate. The positioning component includes a first support seat fixedly installed on the first base and a special-shaped pin fixedly installed on the first support seat. The special-shaped pin is adapted to the positioning hole of the part itself.

[0006] Through the above technical solutions, when processing the rear bracket of the camera, the part is placed on the positioning component, and the part can be completely fixed by using a plurality of first fixing components in cooperation with the second fixing component.

[0007] As a further improvement of the above solution, the first fixing component includes a first oil cylinder fixedly installed on the first base and a fixing plate rotatably installed on the pushing end of the first oil cylinder. Connecting plates are rotatably installed on both sides of the fixing plate. A connecting block is fixedly installed on one side of the first oil cylinder, and one ends of the two connecting plates are rotatably matched with the connecting block.

[0008] Through the above technical solution, when the first oil cylinder starts, one end of the fixing plate will be lifted, so that the other end presses the part.

[0009] As a further improvement of the above solution, a second support seat fixedly installed with the adjacent first base is provided on one side of each first oil cylinder. A limiting block is fixedly installed at one end of each second support seat, and each limiting block is adapted to the adjacent fixing plate.

[0010] Through the above technical solution, the limiting block will limit the height of the part, and cooperate with the downward pressure of the fixing plate to clamp and fix one side of the part.

[0011] As a further improvement of the above solution, the second fixing component includes a second base fixedly installed on one side of the bottom plate, a third support seat fixedly installed on the second base, a second oil cylinder fixedly installed on the second base, and an auxiliary fixing plate arranged on one side of the pushing end of the second oil cylinder.

[0012] Through the above technical solution, when the second oil cylinder starts, it will push the auxiliary fixing plate to clamp the part, so that the front and back movement of the part will be fixed, preventing the part from sliding back and forth during the processing.

[0013] As a further improvement of the above solution, a rotating plate is fixedly installed on one side of the second base. A rotating groove is opened on one side of the rotating plate, and a rotating shaft is rotatably arranged inside the rotating groove. The auxiliary fixing plate is rotatably matched with the rotating plate through the rotating shaft.

[0014] Through the above technical solution, when the second oil cylinder starts, it will push the auxiliary fixing plate. The auxiliary fixing plate cooperates with the rotating plate to squeeze and fix the side of the part.

[0015] As a further improvement of the above solution, a blow nozzle is provided on one side of one of the first bases.

[0016] Through the above technical solution, the blow nozzle will blow away the debris during processing, avoiding the influence of debris on processing.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0018] By providing a positioning assembly, a first fixing assembly, and a second fixing assembly, when fixing and processing parts of different models, the positioning holes of the parts are placed into the positioning assembly. The first fixing assembly is activated to fix the parts by clamping them from above and below, and when the second fixing assembly is activated, it will fix the parts by clamping them from front and back, avoiding gaps between the positioning holes and the special-shaped pins of the positioning assembly that may cause the parts to shake during processing. This setup can be used to process and fix most rear brackets of cameras, preventing a unified processing fixture from being unable to meet the processing requirements of most automotive rear brackets of different models.

A second support seat 403 fixedly installed with the adjacent first base 6 is provided on one side of each first oil cylinder 401. A limiting block 9 is fixedly installed at one end of each second support seat 403. Each limiting block 9 is adapted to the adjacent fixing plate 402. When the first oil cylinder 401 is started, one end of the fixing plate 402 will be pushed up, so that the other end will press the part 2. The limiting block 9 will limit the height of the part, and the part 2 can be clamped and fixed on one side in cooperation with the downward pressure of the fixing plate 402.

[0028] Combined with Figure 1 And Figure 3 , The second fixing component includes a second base 501 fixedly installed on one side of the bottom plate 1, a third support seat 502 fixedly installed on the second base 501, a second oil cylinder 503 fixedly installed on the second base 501, and an auxiliary fixing plate 504 arranged on one side of the pushing end of the second oil cylinder 503.

[0030] The implementation principle of a processing fixture for the rear bracket of a camera in an embodiment of this application is as follows: When processing the rear bracket of a camera, insert the positioning holes of part 2 into the special-shaped pins 302 of two first support seats 301, and the edges of part 2 will also be supported by the limit blocks 9 of multiple second support seats 403. Then start multiple first oil cylinders 401, and the output ends of multiple first oil cylinders 401 will be jacked up, thereby jacking up one end of the fixed plate 402. In this way, with the rotational cooperation of two connecting plates 7, the other end of the fixed plate 402 will descend. Cooperating with the limit blocks 9 on adjacent second support seats 403 can clamp and fix the edges of part 2, so that the up-and-down movement of part 2 will be fixed and locked. Then start the second oil cylinder 503, and the pushing end of the second oil cylinder 503 will push one end of the auxiliary fixed plate 504. In this way, the auxiliary fixed plate 504 will rotate along the rotation axis of the rotating plate 10, thereby cooperating with the third support seat (502) to clamp part 2, so that the front-and-back movement of part 2 will also be fixed, preventing gaps between the positioning holes and the special-shaped pins 302 from causing part 2 to shake during processing. Such a setting can process and fix most rear brackets of cameras, avoiding that a unified processing fixture cannot meet the processing of most automotive rear brackets of different models.

[0031] The above-mentioned implementation manners are only the preferred implementation manners of the present utility model, and cannot be used to limit the protection scope of the present utility model. Any non-substantial changes and substitutions made by those skilled in the art based on the present utility model belong to the protection scope required by the present utility model.
