[0004] During the use of the positioning tooling in this publication number, it is necessary to initially position the sensor by matching the installation bottom plate at the bottom of the sensor with the convex block and the limiting hole at the top of the chassis, and then limit and fix the sensor through the positioning blocks on both sides. However, the shapes of different sensors are diverse, including sensors with circular or square structures. Therefore, the positioning by the cylindrical positioning blocks on both sides in this publication number is not applicable to positioning sensors with different shapes. Thus, a sensor assembly positioning tooling is proposed to solve the above problems. Summary of the Utility Model

[0006] To achieve the above object, the utility model provides the following technical solution: A sensor assembly positioning tooling, including an installation bottom plate, a rotating table is rotatably connected to the top of the installation bottom plate, and a positioning mechanism is arranged on the top of the rotating table.

[0007] The positioning mechanism includes a positioning table, the interior of which is a cavity structure. A fixed block is fixed at the center of the interior of the positioning table. Four side walls of the fixed block are rotatably connected with threaded rods. One end of each threaded rod away from the fixed block penetrates through the positioning table and extends to the outside and is fixedly connected with a gear. A moving block is threadedly connected to the outside of each threaded rod. A connecting slider is fixedly connected to the top of the moving block, and a locking block is fixedly connected to the top of the connecting slider.

A plurality of slots are opened on the top of the mounting base plate and are distributed equidistantly in a surrounding manner. The limit insertion rod is adapted to the slots.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] For this sensor assembly positioning tooling, by setting the positioning mechanism, when it is necessary to position a sensor with a square structure, the sensor is placed in the grooves on the four locking blocks. When it is necessary to position a sensor with a circular structure, the sensor is placed between the four locking blocks. Then, by rotating the rotating table, the four gears can be rotated synchronously, which can drive each threaded rod to rotate, making the four locking blocks move relatively towards the sensor to clamp and position the sensor at the central position on the positioning table, and it is applicable to positioning sensors of different shapes.

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

[0020] Please refer to Figures 1 to 3 , a sensor assembly positioning tooling in this embodiment includes an installation base plate 1. A plurality of installation holes are opened inside the installation base plate 1. The top of the installation base plate 1 is rotatably connected with a rotary table 2, and a positioning mechanism is arranged on the top of the rotary table 2.

[0021] The positioning mechanism includes a positioning table 3. The inside of the positioning table 3 is a cavity structure. A fixed block 6 is fixed at the center of the inside of the positioning table 3. Threaded rods 7 are rotatably connected to the four side walls of the fixed block 6. The end of the threaded rod 7 away from the fixed block 6 penetrates through the positioning table 3 and extends to the outside and is fixedly connected with a gear 8. A moving block 9 is threadedly connected to the outside of the threaded rod 7. The moving block 9 is slidably connected inside the positioning table 3. A connecting slider 10 is fixedly connected to the top of the moving block 9. A locking block 12 is fixedly connected to the top of the connecting slider 10. An annular rack 5 is fixed on the top of the rotary table 2, and the gear 8 meshes with the annular rack 5.

[0022] Among them, four chutes 11 are opened on the top of the positioning table 3, and the connecting slider 10 is slidably connected inside the chutes 11.

[0023] The connecting slider 10 being slidably connected inside the chute 11 has an effect of restricting the moving block 9, so that the moving block 9 can be translated when the threaded rod 7 rotates.

[0024] Please refer to Figure 3 , grooves are opened at the top of the opposite sides of the four locking blocks 12, and the opposite sides of the four locking blocks 12 are arc-shaped structures.

[0025] It should be noted that through the setting of the grooves, it is used to clamp the sensor with a square structure, and the arc surface is used to abut and fit the sensor with a circular structure. Thus, by rotating the rotary table 2 clockwise or counterclockwise, the four locking blocks 12 can move relative to each other or in the opposite direction, so as to be applicable to positioning sensors of different shapes and position the sensor at the central position for convenient assembly.

[0026] In this embodiment, a fixing column 4 is fixedly connected to the bottom of the positioning table 3, and the bottom of the fixing column 4 penetrates through the rotating table 2 and is fixedly connected to the mounting base plate 1.

[0027] It is worth mentioning that the four locking blocks 12 are attached to the top of the positioning table 3, and both the rotating table 2 and the positioning table 3 are circular structures.

[0028] In this embodiment, the rotating table 2 is rotatably connected to the bottom of the positioning table 3. Side plates 13 are fixedly connected to both the left and right sides of the rotating table 2. A limiting insertion rod 14 is inserted into the inside of the right side plate 13. The limiting insertion rod 14 is in an "L" shape. A plurality of slots 15 that are circumferentially and equidistantly distributed are formed in the top of the mounting base plate 1, and the limiting insertion rod 14 is adapted to the slots 15.

[0029] It should be noted that by moving the limiting insertion rod 14 upward and pulling it out of the slot 15, the rotating table 2 can be rotated. After rotation, inserting the limiting insertion rod 14 into the corresponding slot 15 can achieve the limiting effect.

[0030] The working principle of the above embodiment is as follows: When in use, first select the placement method according to the shape of the sensor housing. If a sensor with a square structure needs to be positioned, place the sensor at the groove on the four locking blocks 12. If a sensor with a circular structure needs to be positioned, place the sensor between the four locking blocks 12 and on the top of the positioning table 3. Then hold the side plate 13 and rotate it, and the rotating table 2 can be rotated to drive the annular rack 5 to rotate, so that the four gears 8 meshing with the annular rack 5 rotate synchronously, which can drive each threaded rod 7 to rotate. Under the limiting effect that the connecting slider 10 is slidably connected to the sliding groove 11, the four moving blocks 9 can move toward one side of the fixed block 6, so that the four locking blocks 12 can move relatively closer to the sensor, and the sensor can be clamped and positioned at the central position on the positioning table 3, which is applicable to positioning sensors of different shapes.
