Description

Technical Field

[0001] The utility model relates to the field of motor production, and particularly to a tin dipping test mechanism for a motor stator. Background Technique

[0002] The basic definition of a motor includes converting energy in forms such as electrical energy or chemical energy into mechanical energy. It usually includes components such as an electric motor and an engine. An electric machine is a device that converts electrical energy into mechanical energy, usually composed of components such as a rotor, a stator, and a shaft. According to different working principles and structures, it can be divided into DC motors, AC motors, stepper motors, etc.

[0003] The existing technology has the following problems: After the tin dipping treatment of the motor stator, the impurities on the surface layer of the tin liquid are usually scraped off. During the scraping process, part of the tin liquid leaves the equipment along with the scraping treatment. Since there is no recycling treatment, this part of the tin liquid is wasted, resulting in an increase in production costs. Moreover, since the tin liquid contains harmful substances, if not properly treated, it may cause long-term adverse effects on the environment. Content of the Utility Model

[0004] To solve the above technical problems, a tin dipping test mechanism for a motor stator is provided, which solves the problem of the current increase in production costs.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

The return pipe 12 is communicated with the liquid storage tank.

[0023] As Figure 2 shown in the figure, a top plate 13 corresponding to the workbench 1 is fixedly installed on the upper surface of the side plate 4. A hydraulic rod 14 corresponding to the moving plate 3 is fixedly installed on one side of the side plate 4 close to the moving plate 3. A detector 15 is fixedly installed at the front end of the hydraulic rod 14. The hydraulic rod 14 pushes the detector 15 to test the motor stator after tin dipping. A moving groove 16 is formed at the bottom surface of the top plate 13. Two first lead screws 17 are rotatably installed on the inner wall of the moving groove 16. The two first lead screws 17 are symmetrically distributed about the center line of the moving groove 16. The first lead screws 17 are externally connected to a power source. A slider 18 is arranged inside the moving groove 16. The slider 18 is threadedly connected to both of the first lead screws 17. A telescopic drive rod 19 is fixedly installed at the bottom surface of the slider 18. A clamping assembly 20 is fixedly installed at the lower end of the telescopic drive rod 19. The first lead screws 17 rotate to move the telescopic drive rod 19 on the slider 18 above the stator that has not been dipped in tin. The telescopic drive rod 19 expands to fix the stator that has not been dipped in tin by the clamping assembly 20. The telescopic drive rod 19 contracts. The first lead screws 17 drive the stator that has not been dipped in tin to move above the liquid storage tank 9 through rotation. The telescopic drive rod 19 expands to dip the stator in tin. The telescopic drive rod 19 contracts. The first lead screws 17 drive the stator after tin dipping to continue moving and move the stator after tin dipping above the moving plate 3. The hydraulic rod 14 drives the detector 15 to detect the stator after tin dipping.

[0024] As Figure 3As shown, the clamping assembly 20 includes a main board 21. A fixing groove 22 is formed at the center of the bottom surface of the main board 21. A chamber 23 is formed inside the main board 21 corresponding to the fixing groove 22. A sliding groove 24 is formed on the side surface of the main board 21. The sliding groove 24 communicates the chamber 23 with the fixing groove 22. A sliding plate 25 is arranged inside the sliding groove 24. A driving gear 26 is rotatably installed inside the chamber 23. A rack 27 is fixedly installed on one side of the sliding plate 25 close to the driving gear 26. The driving gear 26 is meshed with the rack 27. A clamping plate 28 is fixedly installed at one end of the sliding plate 25 corresponding to the fixing groove 22. The stator enters between the two clamping plates 28. The driving gear 26 rotates to move the sliding plate 25 on the rack 27, so as to make the two clamping plates 28 approach each other, thereby fixing the stator.

[0025] As Figure 4 shown, a sliding groove 29 is formed on the side surface of the side plate 4 corresponding to the liquid storage tank 9. A second lead screw 30 is rotatably installed on the inner wall of the sliding groove 29. A sliding plate 31 corresponding to the sliding groove 29 is sleeved on the outer surface of the second lead screw 30. An electric push rod 32 is fixedly installed on one side of the sliding plate 31 close to the liquid storage tank 9. A scraping plate 33 corresponding to the liquid storage tank 9 is fixedly installed at one end of the electric push rod 32 away from the side plate 4. Whenever a stator is dipped in tin, after the second lead screw 30 rotates to move the sliding plate 31 to a proper position, the electric push rod 32 contracts to make the scraping plate 33 clean the tin liquid. The scraped tin liquid enters the groove 8 and returns to the liquid storage tank 9 through the discharge pipe 10, the filter box 11 and the return pipe 12 in sequence through the groove 8.

[0026] As Figure 5 shown, a plurality of filter plates 34 are fixedly installed inside the filter box 11. The plurality of filter plates 34 are linearly distributed along the length direction of the filter box 11. The filter plates 34 perform multiple filtrations on the tin liquid passing through the filter box 11, so that the tin liquid can be reused.

[0027] As Figure 5 shown, a feed pipe 35 is fixedly installed on the outer surface of the return pipe 12. The feed pipe 35 is communicated with the return pipe 12. External tin liquid enters the equipment through the feed pipe 35, so as to supplement the lost tin liquid and make the material in the liquid storage tank 9 fill the liquid storage tank 9 in real time.

[0028] As Figure 6 shown, a rotating groove 36 is formed inside the moving plate 3 corresponding to the slide rail 2. A plurality of rollers 37 are rotatably installed on the inner wall of the rotating groove 36. The plurality of rollers 37 are linearly distributed along the length direction of the rotating groove 36. The rollers 37 drive the moving plate 3 to move along the guide rail.

[0029] Working principle: The staff places the stator without tin dipping on the moving plate 3 on the left. The roller 37 rotates to make the moving plate 3 move along the slide rail 2. After the moving plate 3 hits the buffer plate 7, it stops slowly. The first lead screw 17 rotates to make the telescopic drive rod 19 on the slider 18 move above the stator without tin dipping. The telescopic drive rod 19 expands to make the stator enter between the two clamping plates 28. The driving gear 26 rotates to make the slide plate 25 on the rack 27 move, so that the two clamping plates 28 approach each other, and then the stator is fixed. The telescopic drive rod 19 contracts, and the first lead screw 17 drives the stator without tin dipping to move above the liquid storage tank 9. The telescopic drive rod 19 expands to dip the stator in tin. The telescopic drive rod 19 contracts, and the first lead screw 17 drives the stator dipped in tin to continue to move and move the stator dipped in tin above the moving plate 3 on the right. The hydraulic rod 14 drives the detector 15 to detect the stator dipped in tin. After the detection is completed, the moving plate 3 drives the stator to leave.
