[0028] Embodiment:

[0029] Referring to Figures 1 - 6 , an embodiment of the present utility model provides a coating tooling for a motor rotor, which includes an electric slide 1 and a fixture 3 rotatably installed on the top of the electric slide 1. The fixture 3 can be a three-jaw chuck, and further includes: a support plate 2 fixedly connected to the electric slide 1. Among them, a glue applicator 4 is installed on the support plate 2, and a driving part is provided on the support plate 2. The driving part is used to drive the glue applicator 4 to move up and down; a cross plate 5 fixedly connected to the support plate 2. Among them, a clamping plate 6 is installed on the cross plate 5, and a cleaning cotton plate 7 is installed on the clamping plate 6. A pulling part is provided on the support plate 2. When the glue applicator 4 moves upward, the pulling part will drive the cleaning cotton plate 7 to move towards the gun head of the glue applicator 4.

[0030] Specifically, during use, through the setting of the driving part, the connecting plate 42 can drive the glue applicator 4 to move downward or upward, and cooperate with the use of the second motor 33, the glue applicator 4 and the electric slide 1, so that the glue can be evenly coated on the surface of the motor rotor, making the subsequent magnetic steel adhere more firmly. And through the setting of the pulling part, it can drive the cleaning cotton plate 7 to wipe and clean the gun head of the glue applicator 4 during the rising and resetting process of the glue applicator 4, preventing filamentous residual glue from accumulating at the gun head of the glue applicator 4 when the glue is cut off, ensuring the uniformity of the glue discharge in the glue applicator 4, thereby helping to improve the processing quality of the motor rotor and being beneficial to improving the bonding effect of the subsequent magnetic steel.

[0031] The driving part includes: a screw rod 41 rotatably connected to the support plate 2. Among them, a connecting plate 42 is slidably installed on the support plate 2, and the connecting plate 42 is threadedly connected to the screw rod 41. The glue applicator 4 is fixedly connected to the connecting plate 42; a first motor 43 fixedly installed on the top of the support plate 2. Among them, meshing gears 44 are fixedly connected to the output end of the first motor 43 and the surface of the screw rod 41 respectively.

[0032] Specifically, during use, by starting the first motor 43 and driving the gears 44 and the screw rod 41 to rotate, under the action of the thread, the connecting plate 42 can drive the glue applicator 4 to move downward or upward, so as to apply glue to the motor rotor.

[0033] The pulling part includes a moving rod 51 that is horizontally slidably connected to the cross plate 5. A clamping plate 6 is fixedly connected to one end of the moving rod 51.

[0034] Specifically, during use, when the connecting plate 42 drives the glue applicator 4 to move upward, it pulls the pulling rope 53 to slide along the positioning wheel 54. At the same time, the pulling rope 53 will drive the moving rod 51, the clamping plate 6, and the cleaning cotton plate 7 to move towards the glue applicator 4. At the same time, the spring 52 is stretched, which can drive the cleaning cotton plate 7 to wipe the gun head of the glue applicator 4 during the ascending and resetting process of the glue applicator 4, preventing filamentous residual glue from accumulating at the gun head of the glue applicator 4 when the glue is cut off, ensuring the uniformity of the glue discharge in the glue applicator 4, and thus helping to improve the processing quality of the motor rotor. When the connecting plate 42 drives the glue applicator 4 to move downward, it drives one end of the pulling rope 53 to move downward together, making the pulling rope 53 loose, and under the elastic force of the spring 52, the cleaning cotton plate 7 can be quickly reset and move away from the glue applicator 4.

[0038] Specifically, through the setting of the bolt 61 and the fixed disk 62, the disassembly and assembly of the cleaning cotton plate 7 can be facilitated, thus facilitating the subsequent maintenance and replacement of the cleaning cotton plate 7.

[0039] A vertical plate 31 is fixedly connected to the top of the electric slide 1. A turntable 32 is rotatably installed on the vertical plate 31.

[0041] Specifically, during use, by starting the second motor 33 and driving the turntable 32 and the fixture 3 to rotate, the motor rotor fixed on the fixture 3 can be driven to rotate, and by horizontally moving the rotating electronic rotor through the electric slide 1, the glue can be evenly coated on the surface of the motor rotor.

[0042] A circular groove 11 is formed on the surface of the vertical plate 31, and a cylinder 12 is rotatably connected to the turntable 32. The cylinder 12 is rotatably arranged in the circular groove 11.

[0043] Specifically, through the settings of the circular groove 11 and the cylinder 12, the stability of the turntable 32 during rotation can be improved.

[0044] A support plate 9 is fixedly connected to the top of the electric sliding seat 1. A plurality of rotating shafts 10 are rotatably connected in the groove on the top of the support plate 9. The number of the rotating shafts 10 is preferably 7, and they are arranged at equal intervals in the groove on the top of the support plate 9.

[0045] Specifically, through the settings of the support plate 9 and the rotating shafts 10, the motor rotor can be supported assistingly, thereby improving the stability during the coating process of the motor rotor.

[0046] Working principle: During the use of this motor rotor coating tooling, first, the motor rotor is fixed by the fixture 3, then the first motor 43 is started, and the gear 44 and the screw 41 are driven to rotate. Under the action of the thread, the connecting plate 42 drives the glue applicator 4 to move downward, so that the gun head of the glue applicator 4 approaches the surface of the motor rotor. Then, the second motor 33, the glue applicator 4, and the electric sliding seat 1 are started. By the second motor 33, the turntable 32 and the fixture 3 are driven to rotate, the motor rotor fixed on the fixture 3 can be driven to rotate slowly, and the glue liquid is applied to the surface of the motor rotor by the glue applicator 4. At the same time, the rotating motor rotor is driven to move horizontally by the electric sliding seat 1. With the coordinated use of the second motor 33, the glue applicator 4, and the electric sliding seat 1, the glue liquid can be evenly coated on the surface of the motor rotor, so that the subsequent magnetic steel can be bonded more firmly;

[0047] Moreover, when the glue applicator 4 evenly coats the glue liquid on the surface of the motor rotor and shuts off the glue supply, by starting the first motor 43, the connecting plate 42 and the glue applicator 4 are driven to move upward and reset. At the same time, the connecting plate 42 will pull the pull rope 53 to slide along the surface of the positioning wheel 54, so that the pull rope 53 drives the moving rod 51, the clamping plate 6, and the cleaning cotton plate 7 to move towards the glue applicator 4. At the same time, the spring 52 is stretched, and the cleaning cotton plate 7 can be driven to wipe and clean the gun head of the glue applicator 4 during the upward reset process of the glue applicator 4, preventing filamentous residual glue from accumulating at the gun head of the glue applicator 4 when the glue is cut off, ensuring the uniformity of the discharge of the glue liquid in the glue applicator 4, thereby contributing to improving the processing quality of the motor rotor, being beneficial to enhancing the bonding effect of the subsequent magnetic steel, and being more time-saving and labor-saving by adopting the mechanical cleaning method;

[0048] When coating the next motor rotor, the connecting plate 42 and the sealant applicator 4 can be driven to move downward again by the first motor 43. During the downward movement of the connecting plate 42, one end of the pulling rope 53 is driven to move downward together, loosening the pulling rope 53. Under the elastic force of the spring 52, the cleaning cotton plate 7 quickly resets and moves away from the sealant applicator 4. Then, through the coordinated use of the sealant applicator 4, the turntable 32, and the electric slide 1, the motor rotor fixed on the fixture 3 can be coated.

[0049] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
