Guide sleeves 6 are provided on the left and right sides of the cylinder 3. The bottoms of the two guide sleeves 6 are fixedly connected to the top of the support frame 2. A slidable sliding rod 7 is provided through the inner cavity of the guide sleeve 6. The sliding rod 7 penetrates the bottom of the support frame 2 and is fixedly connected to the mobile frame 5. A pressure block 8 is fixedly connected to the central axis of the bottom of the mobile frame 5. A motor housing 10 is provided at the bottom of the pressure block 8. Two rails 11 are fixedly connected to the top of the workbench 1. The tops of the rails 11 are slidably connected with guide grooves 12. The two guide grooves 12 are close to the concave side of the motor housing 10. A plurality of latching teeth are fixedly connected in the grooves, and a ball bearing is fixedly installed on the surface of one side of the motor housing 10 near the plurality of latching teeth, and the ball bearing is rollingly connected to the motor housing 10. A moving rod 13 is fixedly connected on the left and right sides of the two guide grooves 12, and a spring 17 is sleeved on the surface of the moving rod 13. The left and right ends of the spring 17 are welded to the support frame 2 and the fixing cap 15 respectively. The setting of the spring 17 avoids the moving rod 13 from playing an error role in the process of movement, and improves the stability of the moving rod 13 during use. The two moving rods 13 are slidably connected to the two sides of the support frame 2, and the two moving rods 13 are opposite to each other. The sides are fixedly connected with fixing caps 15, and the central axis of the top of the workbench 1 is fixedly connected with a placing table 16, and the stator core 14 is placed in the groove on the top of the placing table 16, and the stator core 14 is locked with the motor housing 10.

[0024] Working principle: When the utility model is used, the user passes through the cylinder 3, and the output end of the cylinder 3 drives the fixed block 4 to move downward, and the movement of the fixed block 4 causes the moving frame 5 to move downward, and then the sliding rod 7 moves downward in the inner cavity of the guide sleeve 6. At this time, when the moving frame 5 slides downward, the moving frame 5 pushes the guide groove 12 to clamp and move at the top of the track 11. Since a ball is installed in the groove of the guide groove 12, the motor housing 10 will not be stuck with the guide groove 12 during the descent process, and then the motor housing 10 is pressed. There will be no deviation during the tightening process, so that the slider 18 will slide downward on the inner wall of the vertical track 9, and then the descent of the movable frame 5 will drive the iron block 8 to press tightly against the top of the motor housing 10, so that the inner cavity of the motor housing 10 will tightly press the placement table 16, and then the motor housing 10 and the placement table 16 will be in a tight fit. At this time, the motor tightening work has been completed, and the cylinder 3 will drive the iron block 8 to rise, and the guide groove 12 will move away from the two sides of the motor housing 10. Finally, the user will take the tightened motor out of the inner cavity of the placement table 16.

[0025] In summary: the clamping device for the three-phase motor housing, through the cylinder 3, the output end of the cylinder 3 will make the movable frame 5 slide downward, through the coordinated use of the movable frame 5, the pressure block 8 and the vertical track 9, the inner cavity of the motor housing 10 will be tightly fitted with the stator core 14, and through the coordinated use of the track 11, the guide groove 12 and the moving rod 13, the stator core 14 and the motor housing 10 play a clamping role in the clamping process to avoid tilting, so that the downward stamping structure and the linked clamping stable housing structure can be adopted, the motor housing and components can be separately clamped, and the housing will not be tilted during the clamping process, which saves labor and improves work efficiency, thereby improving the quality of the product.
