Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0025] Example 1

[0026] Please see Figure 1-4As shown, a pump manufacturing housing welding device includes a testing platform 1. A base 2 is rotatably connected to the center of the upper surface of the testing platform 1 via a shaft. An electric slide body 3 is fixedly connected to the upper surface of the base 2. The electric slide body 3 is a bidirectional screw-driven electric slide. Limiting components 4 are respectively installed on the two sliders of the electric slide body 3. The limiting components 4 include a U-shaped support frame 41. The lower surface of the support frame 41 is fixedly connected to the upper surface of the slider of the electric slide body 3. The inner wall of the support frame 41 is rotatably connected to a V-shaped upper... The lower side wall pipe of the pressure plate 42 and support frame 41 is provided with a connecting rod 43. One end of the connecting rod 43 is fixedly connected to an arc-shaped claw 44. A spring 45 is sleeved on the surface of the connecting rod 43. The spring 45 is located between the claw 44 and the support frame 41. An adjusting rod 46 is fixedly connected to the upper surface of the connecting rod 43. The top end of the adjusting rod 46 is rotatably connected to a sliding seat 47 through a shaft. The upper surface of the sliding seat 47 is slidably connected to the lower surface of the upper pressure plate 42. The electric slide body 3 is electrically connected to a controller, which is used to control the operation of the electric slide body 3.

[0027] Specifically, the base 2 is used to rotate and support the electric slide body 3. The electric slide body 3 is used to drive the two sets of limiting components 4 to move synchronously in opposite directions or in the opposite direction. In use, the water pump housing 8 is placed on the electric slide body 3. The electric slide body 3 is operated so that the two support frames 41 move towards the water pump housing 8 until the pawl 44 tightly abuts against the water pump housing 8 and limits it from both sides. When the pawl 44 abuts against the water pump housing 8, it drives the connecting rod 43 to move outward. When the connecting rod 43 moves, it drives the adjusting rod 46 to move. The adjusting rod 46 drives the sliding seat 47 to slide on the lower surface of the upper pressure plate 42, so that the upper end of the upper pressure plate 42 rotates downward and abuts against the upper surface of the water pump housing 8 for limiting. This provides multi-directional limiting of the water pump housing 8 and improves its stability during welding. This device uses the electric slide body 3 to drive the limiting components 4 to quickly and synchronously limit the side walls and top walls of the water pump housing 8, reducing manual operation and lowering costs.

[0028] The upper pressure plate 42 includes a plate body 421. The surface of the plate body 421 is provided with a plurality of threaded grooves 422. The threaded grooves 422 are threadedly connected to threaded posts 423. The bottom end of the threaded posts 423 is fixedly connected to a spherical pressure block 424.

[0029] Specifically, the threaded groove 422 is used to connect the threaded post 423, and the pressure block 424 is used to hold the water pump housing 8. Depending on the thickness of the water pump housing 8, the initial height and position of the pressure block 424 can be adjusted by rotating the threaded post 423, so as to meet the clamping and fixing requirements of water pump housings 8 of various sizes.

[0030] Example 2

[0031] For comparison with Example 1, please refer to Figure 5As shown, this utility model provides another embodiment. A cleaning component 5 is installed on the testing table 1. The cleaning component 5 includes two supporting scrapers 51. The electric slide body 3 and the two supporting scrapers 51 are arranged in a cross shape. One end of the supporting scraper 51 is fixedly connected to the outer side wall of the electric slide body 3. The upper surface of the supporting scraper 51 is at the same level as the upper surface of the electric slide body 3, and the lower surface of the supporting scraper 51 is at the same level as the upper surface of the testing table 1.

[0032] Specifically, the support scraper 51 is used to cooperate with the electric slide body 3 to support the water pump housing 8 and prevent the water pump housing 8 from tilting when placed.

[0033] The cleaning component 5 also includes two collection ports 52. The electric slide body 3 and the two collection ports 52 are arranged in a cross shape. The collection ports 52 are opened on the surface of the detection table 1. The lower surface of the detection table 1 is fixedly connected to a support base 6.

[0034] Specifically, by rotating the support scraper 51, the welding debris falling on the test table 1 can be pushed into the collection port 52, thereby cleaning the surface of the test table 1 and keeping the surface of the test table 1 clean.

[0035] A driver 7 is fixedly connected to the center of the upper surface of the support base 6. The driving end of the driver 7 is fixedly connected to the shaft of the base 2. The controller is electrically connected to the driver 7 and is used to control the operation of the driver 7.

[0036] Specifically, the driver 7 is used to drive the base 2 to rotate. The rotation of the base 2 drives the electric slide body 3 and the support scraper 51 to rotate. The rotation of the electric slide body 3 can drive the water pump housing 8 to rotate and adjust the welding position, while the rotation of the support scraper 51 can automatically clean the surface of the test table 1.

[0037] A collection box 53 is provided below the collection port 52. A U-shaped guide rail 54 is provided on the outer wall of the collection box 53. The lower surface of the guide rail 54 is fixedly connected to the upper surface of the support base 6.

[0038] Specifically, by inserting the collection box 53 along the guide rail 54, the collection box 53 is kept below the collection port 52, thereby collecting and storing the debris falling from the collection port 52.

[0039] Working principle: During use, the water pump housing 8 is placed on the electric slide body 3 and the support scraper 51. The electric slide body 3 is operated, causing the two support frames 41 to move towards the water pump housing 8 until the pawl 44 tightly abuts against the water pump housing 8, limiting it from both sides. When the pawl 44 abuts against the water pump housing 8, it drives the connecting rod 43 to move outward. When the connecting rod 43 moves, it drives the adjusting rod 46 to move. The adjusting rod 46 drives the sliding seat 47 to slide on the lower surface of the upper pressure plate 42, causing the upper end of the upper pressure plate 42 to rotate downward and abut against the upper surface of the water pump housing 8 for limiting. This provides multi-directional limiting of the water pump housing 8, improving its stability during welding. This device uses the electric slide body 3 to drive the limiting component 4 to achieve rapid and synchronous limiting of the side walls and top walls of the water pump housing 8, reducing manual operation and lowering costs.

[0040] The drive 7 drives the base 2 to rotate, which in turn drives the electric slide body 3 and the support scraper 51 to rotate. The rotation of the electric slide body 3 can drive the water pump housing 8 to rotate and adjust the welding position, while the rotation of the support scraper 51 can push the welding debris that falls on the test table 1 into the collection port 52, thereby cleaning the surface of the test table 1 and keeping the surface of the test table 1 clean.
