[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0022] First embodiment:

[0023] like Figure 1-5As shown, the clamping device for inverter manufacturing provided by this utility model includes: a base 1, a bearing plate 11 on the top of the base 1, a pair of sliding grooves 12 on the top of the bearing plate 11, the sliding grooves 12 being symmetrically arranged on both sides of the bearing plate 11 and having the same structure, a clamping plate 13 being slidably connected to the side wall of the sliding groove 12, a plurality of grooves 14 being provided on the side wall of the clamping plate 13, the grooves 14 being evenly distributed on the side wall of the clamping plate 13 and having the same structure, and a telescopic rod 15 being fixedly connected to the side wall of the groove 14. A first spring 16 is sleeved on the outer side of the telescopic rod 15. The ends of the telescopic rod 15 and the first spring 16 are fixed to the same pad 17. A servo motor 18 is fixed to the side wall of the bearing plate 11. A bidirectional screw 19 is fixed to the output end of the servo motor 18. A pair of connecting blocks 110 are symmetrically threaded to the side wall of the bidirectional screw 19. The connecting blocks 110 are fixed to the clamping plate 13. In use, the frequency converter is placed on the bearing plate 11, which supports the frequency converter. Then, the servo motor 17 is started. 8. The servo motor 18 drives the bidirectional screw 19 to rotate. As the bidirectional screw 19 rotates, the connecting blocks 110 on both sides move in opposite directions, causing the clamping plates 13 on both sides to move closer or further apart. At the same time, the clamping plates 13 slide within the slide groove 12. Then, under the action of the clamping plates 13 moving closer together, the pad 17 first contacts the surface of the frequency converter. By squeezing the pad 17, the telescopic rod 15 and the first spring 16 can extend and retract. At this time, the elasticity of the first spring 16 can apply pressure to the pad 17. A certain reaction force allows multiple pads 17 to be inserted into the uneven surface of the inverter, making it compatible with the inverter's surface. Then, the clamping plate 13 can be used to clamp and fix the inverter. During this process, the clamping plates 13 on both sides move closer to each other to clamp and fix the inverter during production, improving the stability of the inverter during production. At the same time, the movement of the clamping plate 13 can clamp and fix inverters of different sizes, and the pads 17 can increase the full contact with the inverter surface.

[0024] Second embodiment:

[0025] like Figures 1-4As shown, a slide cylinder 2 is fixedly connected to the top of the base 1. A slide plate 21 is slidably connected to the inner wall of the slide cylinder 2. The slide plate 21 is fixedly connected to the support plate 11. A bracket 22 is fixedly connected to the side wall of the slide plate 21. A second spring 23 is fixedly connected to the side wall of the bracket 22. An insert block 24 is fixedly connected to the end of the second spring 23. A pull plate 25 is fixedly connected to the side wall of the insert block 24. The pull plate 25 penetrates the wall of the bracket 22 and is slidably connected to it. Multiple slots 26 are opened on the side wall of the slide cylinder 2. The slots 26 are evenly distributed on the side wall of the slide cylinder 2 and have the same structure. In use, first hold the pull plate 25 and pull it. The insert 24 is pulled out of the side wall of the slot 26, and then the support plate 11 is raised so that the slide plate 21 slides in the slide cylinder 2. When it slides to a suitable height, the insert 24 can be aligned with one of the slots 26. Then the pull plate 25 can be released, and the second spring 23 can apply a certain reaction force to the insert 24, pushing the insert 24 into the side wall of the slot 26, thus fixing the slide plate 21. During this process, the sliding of the slide plate 21 can adjust the height of the support plate 11 during use, increasing the adaptability to people of different heights and improving the practicality of the support plate 11.

[0026] Third embodiment:

[0027] like Figure 4 As shown, the sidewall of the insert 24 is evenly provided with multiple slots 3, and the sidewall of the slot 26 is fixedly connected with multiple elastic pieces 31. The elastic pieces 31 are evenly distributed on the sidewall of the slot 26 and have the same structure. The sidewall of the elastic piece 31 is fixedly connected with a rubber strip 32. During use, when the insert 24 is inserted into the sidewall of the slot 26, the insert 24 will squeeze the rubber strips 32 on both sides, causing the elastic pieces 31 to deform to a certain extent. When the slot 3 moves to the position corresponding to the rubber strip 32, the elasticity of the elastic piece 31 can push the rubber strip 32 into the sidewall of the slot 3. At this time, a certain friction force will be generated through the contact between the two. During this process, the rubber strip 32 can be inserted into the sidewall of the slot 3 to prevent the insert 24 from shaking after being inserted into the sidewall of the slot 26, improve the firmness of the insert 24 on the sidewall of the slot 26, and increase the fixing effect of the insert 24.

[0028] Fourth embodiment:

[0029] like Figure 3 As shown, an elastic plate 7 is fixed to the side wall of the pull plate 25. In use, by placing the hand between the elastic plate 7 and the pull plate 25, the elastic plate 7 is opened. At the same time, the elasticity of the elastic plate 7 will apply a certain reaction force to the hand and press the hand. In this process, it can play a role in fixing the hand and the pull plate 25, improving the anti-drop effect when holding and pulling the pull plate 25, and increasing the firmness between the two.

[0030] Working principle: The clamping plates move closer to each other, causing the pad 17 to first contact the surface of the inverter. When it moves further, it squeezes the pad 17, causing the telescopic rod 15 and the first spring 16 to extend and retract. At the same time, the first spring 16 applies a certain reaction force to the pad 17, so that multiple pads 17 are stuck on the irregular surface of the inverter, thereby adapting to the surface of the inverter, increasing the clamping area of ​​the inverter, and improving stability.

[0031] The above embodiments are merely one of the preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any modifications or refinements made to the main design concept and spirit of this utility model that are not of substantial significance, but solve the same technical problem as this utility model, should be included within the scope of protection of this utility model.
