[0027] The utility model will be described in detail below in combination with the drawings and examples.

[0028] As Figure 1 and Figure 3 As shown, the all-round camera lower cover positioning tool includes a placement platform 1, and a plurality of processing intervals are arranged on the placement platform 1. A lifting drive mechanism 2 is fixedly connected below the placement platform 1 and located between adjacent processing intervals. The output end of the lifting drive mechanism 2 is horizontally rotatably connected with a positioning rod 3 located between adjacent processing intervals. Adjacent positioning rods 3 are in synchronous contact or separation with workpieces in the plurality of processing intervals in response to the lifting drive mechanism 2. In this embodiment, a vertically placed air cylinder 21 is selected as the power source of the lifting drive mechanism 2. The horizontal height of the positioning rod 3 is adjusted by the extension and contraction of the air cylinder 21. When the output end of the air cylinder 21 is extended, the horizontal height of the positioning rod 3 is increased, and the positioning rod 3 is away from the processing interval, so that the operator can take the all-round camera lower cover from the processing interval and place the all-round camera to be processed. Then, the positioning rod 3 is transversely arranged between two processing intervals by horizontal rotation. When the air cylinder 21 is contracted, the positioning rod 3 is displaced with the movement of the output end of the air cylinder 21, and the end edge of the all-round camera lower cover is fixed, thereby ensuring the stability of the all-round camera lower cover during processing. During the installation and disassembly operation, the plurality of air cylinders 21 realize synchronous movement through the control of the air valve. During use, the plurality of air cylinders 21 can replace the traditional single installation and disassembly one by one, which affects the processing efficiency. In addition, the synchronous operation of the plurality of air cylinders 21 can realize the rapid disassembly and assembly of the all-round camera lower cover.

[0029] As Figure 2 and Figure 4As shown, a plurality of positioning edge groups 4 are arranged at the processing interval, and the positioning edge groups 4 are formed with embedding parts matched with the workpiece for limiting the horizontal displacement of the workpiece. The positioning edge group 4 includes a plurality of positioning edge points 41 surrounding the workpiece, and the number of the positioning edge points 41 on one side of the workpiece is at least two. The positioning edge group 4 also includes a plurality of positioning edge strips 42 located in the workpiece, and the positioning edge strips 42 are symmetrically arranged and have a gap matched with the wall thickness of the workpiece between the positioning edge points 41. Specifically, the positioning edge strips 42 include a left edge strip 43 and a right edge strip 44, and the left edge strip 43 and the right edge strip 44 have a height difference. In this embodiment, the top part of the surround camera near one side is recessed downward to form a recess cavity for accommodating the camera element. Therefore, the left edge strip 43 and the right edge strip 44 arranged in this application have a height difference, and the height difference is the depth of the recess cavity. By means of the height difference between the left edge strip 43 and the right edge strip 44, better foolproof effect can be achieved during installation, and the installation direction of the operator is limited to make the processing more standardized. Furthermore, the positions of the recess cavities are arranged at equal intervals along the longitudinal and latitudinal directions, which is beneficial to processing.

[0030] In this embodiment, in order to improve the applicability of the placement platform 1, the output end of the air cylinder 21 is threadedly connected with a transition column 22 penetrating through the placement platform 1, and the positioning rod 3 is horizontally rotationally connected to the top end of the transition column 22 through a shaft. The positioning rod 3 and the top end of the transition column 22 are rotationally connected by the shaft, so that the positioning rod 3 can be arbitrarily rotated in the horizontal direction. Furthermore, the transition column 22 is connected with the output shaft of the air cylinder 21 in a threaded manner, so that the operator can select a positioning rod 3 with a suitable length according to the specifications of the workpiece to be processed. In this embodiment, the two ends of the positioning rod 3 are located above the adjacent positioning edge points 41 between adjacent processing regions, so that when the surround camera lower cover is installed into the positioning edge points 41, the end of the positioning rod 3 can abut against the edge of the surround camera, thereby minimally abutting against the workpiece to achieve fixation.

[0031] Working process: when the operator operates the machine, firstly, the operator starts the machine and makes the output end of the cylinder 21 extend by controlling the cylinder 21, so as to drive the horizontal height of the positioning rod 3 to be raised, then the operator installs the ring-vision camera in sequence in the array distributed processing interval, the ring-vision camera lower cover is clamped in the gap between the positioning edge point 41 and the positioning edge strip 42 through the positioning edge point 41 and the positioning edge strip 42 arranged in the processing interval, so as to realize the limiting of the ring-vision camera in the horizontal direction, and the positioning edge strip 42 is composed of the left edge strip 43 and the right edge strip 44 with height difference, when the ring-vision camera lower cover is installed, the concave cavity formed by the downward recess on the ring-vision camera lower cover can cooperate with the operation of the operator to place the ring-vision camera lower cover, and the asymmetric ring-vision camera lower cover array is arranged on the placement platform 1, then the cylinder 21 drives the positioning rod 3 to move downward, after the positioning rod 3 rotates, the two ends of the positioning rod 3 are directed to the positioning edge point 41 of the two adjacent processing intervals, and after moving downward, the two ends of the positioning rod 3 just touch the edges of the two ring-vision camera lower covers at the same time, so as to fix the ring-vision camera lower cover in the vertical direction, and the positioning edge group 4 is arranged, so that the displacement of the ring-vision camera in multiple directions is limited during the processing, so as to improve the stability during the processing, and the accuracy is guaranteed. After the processing is completed, the cylinder 21 is synchronously actuated, so as to simultaneously release the limiting of the ring-vision camera lower cover, and the operator can process the ring-vision camera lower cover in batches.

[0032] The preferred embodiments of the utility model are described above, the protection scope of the utility model is not limited to the above-mentioned embodiments only, any technical scheme belonging to the utility model idea is also within the protection scope of the utility model. It should be noted that, for the ordinary skilled in the art, some improvements and decorations are also considered as the protection scope of the utility model without departing from the principle of the utility model.
