Description

Technical Field

[0001] The utility model relates to the technical field of motor processing, in particular to a motor shell spraying device. Background Art

[0002] An electric motor, commonly known as a motor, is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. Its main function is to generate driving torque as a power source for electrical appliances or various machines. The motor casing needs to be sprayed with paint after processing. Spraying paint can prevent the metal casing from direct contact with harmful gases such as oxygen and moisture and being oxidized and corroded, thereby extending the service life of the motor.

[0003] After searching, the utility model with announcement number CN213494469U discloses an environmentally friendly motor casing spraying device, including a base plate, a vertical plate is vertically arranged on the rear end of the upper surface of the base plate, and a rotating shaft is rotatably arranged on the front side of the vertical plate. The environmentally friendly motor casing spraying device is achieved by arranging the motor casing on the outside of the threaded rod, the rear end of the casing contacts the positioning plate, and the second baffle is rotated to drive the outer cylinder and the threaded sleeve to move along the threaded rod. The threaded sleeve squeezes the support rod until the support block is in close contact with the inner wall of the motor casing to fix the casing. The motor drives the rotating shaft to rotate when it works, thereby driving the motor casing to rotate. The spray head moves along the electric guide rail to spray paint on the surface of the casing. There is no obstruction on the surface of the motor casing, so that the casing can be covered with paint more comprehensively and evenly, and the spraying effect is better.

[0004] The device also has the following disadvantages during use: when in use, the threaded sleeve is pressed against the support rod to fix it to the inner wall of the housing, but the threaded sleeve needs to be unscrewed each time it is clamped, which wastes a lot of time and reduces the efficiency of housing clamping. In addition, positioning is inconvenient during the clamping process. Therefore, it is very necessary to propose a motor housing spraying device. Utility Model Content

[0029] A clamping mechanism is arranged on the workbench 1, and is used to clamp and fix the shell, and drive the shell away from the conveyor 2. A motor 4 is provided on one side of the spray hood 3. The motor 4 is used in conjunction with the clamping mechanism to drive the shell to rotate. The shell can be driven to move into the spray hood 3 through the conveyor 2, and can be clamped by the clamping mechanism and driven away from the conveyor 2. At the same time, after clamping, the shell can be driven to rotate by the motor 4, so that it rotates while spraying, thereby improving the spraying effect.

[0030] In the utility model, the clamping mechanism includes two movable plates 9 that are slidably arranged on the top of the workbench 1, and the two movable plates 9 are respectively located on both sides of the conveyor 2. An electric push rod 5 is arranged on one side of the spray hood 3. The output end of the electric push rod 5 is transmission-connected with the two movable plates 9 to drive the two movable plates 9 to approach each other to clamp the outer shell. By starting the electric push rod 5, the two movable plates 9 can be driven to move relative to each other, so that the outer shell can be clamped, which is convenient to use.

[0031] In the utility model, conical blocks 10 are rotatably provided on the sides of the two movable plates 9 that are close to each other, and an extension shaft 24 is fixedly provided at one end of one of the conical blocks 10. The output end of the motor 4 is connected to the extension shaft 24 to drive the outer shell to rotate after clamping. By starting the motor 4, the extension shaft 24 can be driven to rotate, and the rotation of the extension shaft 24 can drive the conical block 10 to rotate, so that it can drive the outer shell to rotate after clamping, and in the process of clamping, the outer shell can be driven to move upward through the inclined surface of the conical block 10, so that the bottom of the outer shell is away from the conveyor 2, which can effectively prevent the outer shell from colliding with the conveyor 2 during rotation.

[0032] In the utility model, the output end of the electric push rod 5 is fixedly connected to the corresponding moving plate 9, a gear 14 is rotatably provided at the bottom of the workbench 1, and a rack 13 meshing with the gear 14 is fixedly provided at the bottom of the moving plate 9. The moving plate 9 can be driven to move by starting the electric push rod 5. During the movement of the moving plate 9, another moving plate 9 can be driven to move through the rack 13 and the gear 14, so that they are close to each other, which is convenient for clamping the outer shell.

When the movable plate 9 drives the extension shaft 24 to move, it can drive the third clamping ring 21 to move in the extension tube 23, so that the third clamping ring 21 is engaged with the fourth clamping ring 22. At this time, the rotation of the motor 4 can drive the extension shaft 24 to rotate through the fourth clamping ring 22 and the third clamping ring 21, thereby driving the outer shell to rotate, which is convenient to use.

[0034] In particular, a positioning belt 8 located in the shell base is fixedly provided on the outer side of the conveyor belt of the conveyor 2. The shell can be positioned by setting the positioning belt 8 so that it will not shift during the placement process, so that the clamping effect will not be affected.

[0035] In particular, a second connecting plate 15 is fixedly provided on the top of the workbench 1, and the second connecting plate 15 is rotatably sleeved on the extension tube 23. A rotating shaft 18 is rotatably provided on one side of the second connecting plate 15, and the rotating shaft 18 is clamped with the rotating roller of the conveyor 2. The outer walls of the rotating shaft 18 and the extension tube 23 are fixedly sleeved with synchronous wheels 16.

[0037] Working principle: When in use, the device is powered on, and a proper amount of paint is added to the paint box 6, and then the shell is placed on the conveyor 2, and the positioning belt 8 is stuck in the base, and then the electric push rod 5 is started to drive the moving plate 9 to move, and the movement of the moving plate 9 can drive the first connecting plate 12 to move, and the movement of the first connecting plate 12 can drive the second clamping ring 20 to move, so that the second clamping ring 20 approaches the first clamping ring 19 and engages with the first clamping ring 19, and at the same time, the motor 4 is started to drive the extension cylinder 23 to rotate, and the rotation of the extension cylinder 23 can drive the rotating shaft 18 to rotate through the synchronous wheel 16 and the synchronous belt 17, and the rotation of the rotating shaft 18 can drive the conveyor 2 to transport the shell through the first clamping ring 19 and the second clamping ring 20 until the shell is transported between the two moving plates 9, and the electric push rod 5 is started. The movable plate 9 is driven to move in the opposite direction. During the movement of the movable plate 9, the rack 13 and the gear 14 can be used to drive another movable plate 9 to move. At the same time, the second clamping ring 20 can be driven away from the first clamping ring 19, and the third clamping ring 21 can be moved in the extension tube 23, so that the third clamping ring 21 and the fourth clamping ring 22 are engaged, and the two conical blocks 10 are driven to approach each other to clamp the outer shell. The clamping can also drive the outer shell to move upward, so that the outer shell is separated from the positioning belt 8. At this time, the motor 4 is started again to drive the extension tube 23 to rotate, and the extension shaft 24 can be driven to rotate through the third clamping ring 21 and the fourth clamping ring 22, so that the outer shell can be driven to rotate through the conical block 10, and the spray pump 7 is started to extract the paint in the paint box 6, and spray it to the outer shell through the nozzle 11, while rotating and spraying.
