Detailed Implementation

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification. Example 1

[0023] like Figures 1-5 As shown, this utility model provides a technical solution: a positioning device for processing an automotive air conditioning expansion valve body, including a base 1 and an adjusting seat 2. The adjusting seat 2 is movably installed inside the base 1. A groove 201 is provided on the top of the adjusting seat 2. A first clamp 3 and a second clamp 4 are movably installed inside the groove 201. The first clamp 3 and the second clamp 4 have the same structure but opposite directions. A fixing plate 5 is fixedly connected to the top of the adjusting seat 2. A first motor 51 is fixedly installed on one side of the fixing plate 5. A second motor 6 is fixedly installed inside the adjusting seat 2. A movable rod 31 is movably installed at the bottom of the first clamp 3. A movable rod 41 is movably installed at the bottom of the second clamp 4. A disc 61 is fixedly connected to the output end of the second motor 6. One end of the movable rod 31 and one end of the movable rod 41 are both movably installed on the top of the disc 61.

[0024] In this embodiment, the expansion valve is placed inside the clamping plate 32 and the clamping plate 42. Then, the second motor 6 is started to drive the disc 61 to rotate. When the disc 61 rotates to the right, it will simultaneously drive the movable rod 31 and the movable rod 41 to move, and together pull the first clamp 3 and the second clamp 4 closer to each other. The clamping plate 32 and the clamping plate 42 clamp and limit the expansion valve on both sides. When the second motor 6 drives the disc 61 to reverse, the first clamp 3 and the second clamp 4 will move away from each other, thereby releasing the limitation on the expansion valve and facilitating quick clamping and positioning of the expansion valve. Example 2

[0025] like Figures 1-5 As shown, a connecting rod 21 is fixedly connected to the bottom of the adjusting seat 2. The bottom of the connecting rod 21 is movably connected to the bottom of the inner wall of the base 1. A worm gear 22 is fixedly installed on the bottom of the outer wall of the adjusting seat 2. A throttle 11 is movably installed on the surface of the base 1. A worm 12 is fixedly connected to one end of the throttle 11. The other end of the worm 12 is movably connected to the inner wall of the base 1. The surface of the worm 12 meshes with the side of the worm gear 22. A clamping plate 32 is movably installed inside the first clamp 3. A clamping plate 42 is movably installed inside the second clamp 4. A limit ring 33 is fixedly installed on the outer wall of the clamping plate 32. The limit ring 33 is movably installed inside the first clamp 3. A ball bearing 34 is provided inside the first clamp 3. The side of the ball bearing 34 is in contact with the outer wall of the clamping plate 32. A transmission rod 52 is fixedly connected to the output end of the first motor 51. A slide rod 53 is slidably installed inside the transmission rod 52. One end of the slide rod 53 is fixedly connected to one side of the outer wall of the clamping plate 32.

[0026] In this embodiment, rotating the throttle 11 drives the worm 12 to rotate. The worm 12 meshes with the worm wheel 22, causing the adjusting seat 2 to rotate as well. At this time, the expansion valve on the top of the adjusting seat 2 rotates, adjusting its processing position. Due to the self-locking property between the worm 12 and the worm wheel 22, the rotation of the adjusting seat 2 can be prevented from affecting the positioning accuracy. When the first clamp 3 moves towards the expansion valve, it drives the slide rod 53 to slide out inside the transmission rod 52. When the first motor 51 drives the transmission rod 52 to rotate, it engages with the slide rod 53, thereby driving the clamping plate 32 to rotate as well, flipping the fixed expansion valve. This facilitates multi-angle processing of the expansion valve without the need for disassembly and secondary fixing, thus improving the processing effect.

[0027] The working principle of this embodiment is as follows: The expansion valve is placed inside the clamping plate 32 and the clamping plate 42. Then, the second motor 6 is started to drive the disc 61 to rotate. The disc 61 rotates to the right and pulls the first clamp 3 and the second clamp 4 closer to each other. When the first clamp 3 moves towards one end of the expansion valve, it will drive the slide rod 53 to slide out inside the transmission rod 52, which facilitates quick clamping and positioning of the expansion valve. By turning the handle 11, the worm and worm wheel 22 are driven to rotate. At this time, the expansion valve on the top of the adjusting seat 2 rotates to adjust its processing position. The first motor 51 drives the transmission rod 52 and the slide rod 53 to rotate, flipping the fixed expansion valve to facilitate multi-angle processing of the expansion valve.

[0028] The above merely describes preferred embodiments of the present application, and is not intended to limit the present application in other forms, and any skilled person in the art can modify or change the above disclosed technical content to equivalent embodiments applied to other fields with equivalent changes, but any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present application without departing from the technical scheme of the present application still falls within the protection scope of the present application.
