Description

Technical Field

[0001] The utility model belongs to the field of motor rotor processing, and particularly relates to a glue application device for a motor rotor. Background Technique

[0002] A motor refers to an electromagnetic device that realizes the conversion or transmission of electrical energy based on the law of electromagnetic induction. It is divided into a DC motor and an AC motor according to the type of working power supply.

[0003] For the inner groove type rotor of a motor, multiple iron sheets are stacked and installed outside the motor shaft. After the iron sheets are pressed tightly, dot gluing is carried out. Usually, a dispensing head is used to apply glue to each slot on the circumference of the rotor. However, during the glue application process, the glue will spread outwards due to gravity, resulting in bulges at the glue application parts. When the rotor rotates, the bulging parts will rub against the inner wall of the motor stator, affecting the use. Content of the Utility Model

Specific implementation mode

[0020] As Figures 1 to 5 shown, the present utility model discloses a glue application device for a motor rotor. The adopted technical solution is that it includes a bottom plate 1. A lifting device 5 is slidably installed at the rear end of the top surface of the bottom plate 1. The movable end of the lifting device 5 is fixedly installed with a fixed plate 15. A spray pipe 18 is fixedly installed at the bottom of the outer end of the fixed plate 15. A fixed column 8 is fixedly installed at one end of the front part of the bottom plate 1. A scraper 10 is installed inside the fixed column 8 through a hydraulic rod 1. A lower ejector pin 12 is rotatably installed in the middle of the bottom plate 1. An upper ejector pin 19 is rotatably installed above the lower ejector pin 12. The present utility model is provided with a hydraulic rod 1 at one end of the front part of the bottom plate 1. Through the telescoping of the hydraulic rod 1, the scraper 10 is moved. After the glue is applied to the rotor, the circumference of the rotor is scraped to prevent the glue from spreading outwards and causing the glued part to bulge, ensuring that when the rotor rotates, the rotor will not rub against the inner wall, and ensuring the normal use of the motor.

[0021] The lifting device 5 includes a slideway 501. A motor 1 502 is fixedly installed above the slideway 501. The rotating shaft of the motor 1 502 is fixedly installed with a lead screw 503. A slider 504 is installed on the outer circumference of the lead screw 503. The slider 504 is slidably installed in the slideway 501. The outer side of the slider 504 is fixedly installed with a fixed plate 15. By rotating the motor 1 502, the lead screw 503 rotates. The lead screw 503 meshes with the slider 504 to realize the up and down sliding of the slider 504 in the slideway 501, driving the fixed plate 15 to lift and lower.

[0022] The upper part of the lead screw 503 is rotatably installed inside the support seat 507. The support seat 507 is fixedly installed on the upper part of the inner side of the slideway 501. The lower part of the lead screw 503 is fixedly installed with a rotating column 505. The rotating column 505 is rotatably installed in the rotating seat 506. The rotating seat 506 is fixedly installed at the lower end of the inner side of the slideway 501. The upper part of the lead screw 503 rotates inside the support seat 507 to keep the upper part of the lead screw 503 rotating stably. The rotating column 505 rotates inside the rotating seat 506 to keep the lower part of the lead screw 503 rotating stably.

[0023] A support column 2 is fixedly installed on the bottom surface of the bottom plate 1, and a moving wheel 3 is fixedly installed at the bottom of the support column 2. Multiple moving wheels 3 are used for the moving work of the gluing device through rotational adjustment and rotation.

[0024] At the top of the outer end of the fixed plate 15, a liquid tank 16 and a high-pressure pump 17 are fixedly installed. The high-pressure pump 17 is connected to the spray pipe 18. The inside of the liquid tank 16 is used to hold glue liquid. The high-pressure pump 17 is used to transport the glue to the spray pipe 18, and the spray pipe 18 is used for the glue to flow into the inner groove of the rotor.

[0025] At the rear end of the top surface of the bottom plate 1, a moving track 4 is fixedly installed. Inside the moving track 4, a second hydraulic rod 13 is fixedly installed. Outside the second hydraulic rod 13, a moving block 14 is fixedly installed. The moving block 14 is slidably installed inside the moving track 4. At the top of the moving track 4, a lifting device 5 is fixedly installed. The second hydraulic rod 13 expands and contracts to enable the moving block 14 to slide inside the moving track 4, realizing the forward and backward movement of the lifting device 5, which is used to adjust the forward and backward position of the spray pipe 18.

[0026] In the middle of the bottom plate 1, a second motor 11 is fixedly installed. A lower thimble 12 is fixedly installed on the rotating shaft of the second motor 11. The second motor 11 rotates to drive the lower thimble 12 to rotate. The maximum rotational speed of the second motor 11 is not sufficient to cause the glue to generate centrifugal motion.

[0027] At the other end of the front part of the bottom plate 1, a bracket 6 is fixedly installed. At the top inside the bracket 6, a third hydraulic rod 7 is fixedly installed. At the bottom of the third hydraulic rod 7, an upper thimble 19 is rotatably installed. The third hydraulic rod 7 expands and contracts to fix the rotor with the upper thimble 19, and the upper thimble 19 rotates to cooperate with the synchronous rotation of the rotor.

[0028] The working principle of this motor rotor gluing device: When a motor rotor gluing device is in use, first place the semi-finished rotor vertically on the lower thimble 12. Control the third hydraulic rod 7 to extend, and the upper thimble 19 presses the motor shaft of the rotor. Control the first motor 502 to rotate, driving the lead screw 503 to rotate. The rotating column 505 at the lower part of the lead screw 503 rotates inside the rotating seat 506. The threaded part of the lead screw 503 meshes with the slider 504 and rotates. The slider 504 slides inside the slideway 501, and the fixed plate 15 moves, making the spray pipe 18 close to the gluing position. The second hydraulic rod 13 expands and contracts, the moving block 14 slides inside the moving track 4, and the lifting device 5 moves forward and backward to adjust the forward and backward position of the spray pipe 18. The first hydraulic rod 9 extends, the scraper 10 moves, and the scraper 10 presses against the outer circumference of the rotor. The second motor 11 rotates, the lower thimble 12 rotates, and the rotor rotates synchronously to apply glue to multiple inner sides of the rotor circumference. The scraper 10 scrapes the outer side of the inner groove to prevent the gluing part from bulging. As the glue solidifies, then the scraper 10 moves away from the rotor to complete the gluing.

[0029] Although the specific embodiments of the present utility model have been described in detail above, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the gist of the present utility model, and modifications or variations that do not involve creative labor are still within the protection scope of the present utility model.
