The grinding type needs to use high-speed rotating grinding discs, etc. to grind the shell surface, and the operation is cumbersome. The ball grinding type has no filtering structure, and the powdered materials ground off will affect the friction between the abrasive and the shell. Therefore, a shell polishing device for electric vehicle drum brake production is proposed. A filter screen is equidistantly arranged in the laminate. The abrasive drum brake and the abrasive rotate and rub on the filter screen, and the powdered materials ground off can flow through the filter screen to the bottom of the barrel body, and will not affect the friction between the abrasive and the shell.

The fixing assembly includes a cylinder body connected to one side of the plate sleeve through a threaded groove. A plug rod is sleeved inside the cylinder body. A compression spring is sleeved on the outer side of the plug rod located inside the cylinder body.

[0007] By adopting the above technical solution, the driving motor drives the vertical rod and the stirring rod outside it to stir the abrasive and the housing, causing the abrasive to rub against the housing to polish the housing. The powder generated during polishing falls to the bottom of the barrel through the filter screen. The side plate can be moved up and down to adjust the height of the transparent barrel cover, and the fixing component is used to fix the side plate.

[0008] Specifically, a guide plate is fixed to the bottom of the barrel by bolts, and a discharge slot is formed on one side of the barrel away from the plate sleeve.

Specific embodiments

[0022] In order to make the technical means, creative features, achieved purposes and functions realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Filter screens are equidistantly arranged in the laminate. The abrasive drum brake rotates and rubs against the abrasive on the filter screen, and the powdered materials polished off can flow through the filter screen to the bottom of the barrel body, without affecting the friction between the abrasive and the shell. As Figures 1-4 shown, a shell polishing device for the production of electric vehicle drum brakes according to the present utility model includes a barrel body 1. A laminate 7 is fixedly installed inside the barrel body 1 through bolts. Filter screens 8 are welded equidistantly inside the laminate 7. A stirring component 2 is arranged at the bottom of the laminate 7. The stirring component 2 includes a protective box 201 fixedly installed at the bottom of the laminate 7 through bolts. A driving motor 202 is installed inside the protective box 201 through a mounting bracket. The output shaft of the driving motor 202 located at the top of the laminate 7 is connected to a vertical rod 203 through a connecting sleeve. Stirring rods 204 are welded equidistantly on the outside of the vertical rod 203;

[0024] A plate sleeve 3 is fixedly installed on one side of the barrel body 1 through bolts. A side plate 4 is sleeved at the top of the plate sleeve 3. A transparent barrel cover 5 is fixedly installed at the top of one side of the side plate 4 through bolts. A fixing component 6 is arranged on one side of the plate sleeve 3. The fixing component 6 includes a cylinder body 601 connected to one side of the plate sleeve 3 through a threaded groove. A pin rod 602 is sleeved inside the cylinder body 601. A compression spring 603 is sleeved on the outside of the pin rod 602 located inside the cylinder body 601.

[0025] During use, the driving motor 202 drives the vertical rod 203 and the stirring rods 204 on its outside to stir the abrasive and the shell, so that the abrasive and the shell generate friction to polish the shell. The powdered materials generated during polishing fall to the bottom of the barrel body 1 through the filter screen 8. Moving the side plate 4 up and down can adjust the height of the transparent barrel cover 5. The fixing component 6 is used to fix the side plate 4.

[0026] Exemplarily, as Figure 2 shown, the present utility model further includes that a guide plate 9 is fixedly installed at the inner bottom of the barrel body 1 through bolts, and a discharge chute 10 is formed on one side of the barrel body 1 away from the plate sleeve 3.

[0027] During use, the powder material falling to the inner bottom of the barrel body 1 is guided by the guide plate 9 and flows out from the discharge chute 10.

[0028] Exemplarily, as Figure 4 shown, the present utility model further includes that a limiting ring 604 is fixedly sleeved outside one end of the compression spring 603 on the pin rod 602, and a limiting block 605 is connected to one end of the pin rod 602 through a threaded groove.

[0029] During use, the compression spring 603 pushes the pin rod 602 to move through the limiting ring 604, and the limiting block 605 can prevent the pin rod 602 from falling off from the cylinder body 601.

[0030] Exemplarily, as Figure 3 shown, the present utility model further includes that a plurality of card holes 11 corresponding to the pin rods 602 are formed at equal intervals on one side of the side plate 4, and a handle 12 is connected to one side of the side plate 4 at the top of the card hole 11 through a threaded groove.

[0031] During use, the formation of the card holes 11 facilitates the insertion of one end of the pin rod 602, and the arrangement of the handle 12 facilitates the personnel to hold and move the side plate 4 up and down.

[0032] Exemplarily, as Figure 1 shown, the present utility model further includes that a timing switch 13 is arranged on one side of the barrel body 1, and the current output end of the timing switch 13 is electrically connected to the current input end of the driving motor 202 through a power cord.

[0033] During use, the driving motor 202 can be controlled to work and its working duration through the timing switch 13.

[0034] Exemplarily, as Figure 1 shown, the present utility model further includes that the transparent barrel cover 5 is made of polycarbonate material.

[0035] During use, the transparent barrel cover 5 made of polycarbonate material has high strength, is not easy to wear, and is convenient for personnel to observe the situation inside the barrel body 1.

[0036] When the present utility model is in use, the user connects the device to an external power source, pours abrasive materials such as steel balls, diamond grains or sand grains into the barrel body 1, and places the electric vehicle drum brake housing to be polished into the barrel body 1;

[0037] The abrasive material poured into the barrel body 1 and the drum brake housing both fall on the laminar plate 7 and the filter screen 8 inside it. The driving motor 202 is turned on to drive the vertical rod 203 and the stirring rod 204 outside it to rotate, stirring the abrasive material and the drum brake housing. Friction occurs between the abrasive material and the surface of the drum brake housing to polish and buff it. The powder generated during polishing passes through the filter screen 8 and falls into the barrel body 1, without affecting the polishing of the housing.

[0038] The operator pulls the latch rod 602 to move one end out of the locking hole 11, and then can hold the handle 12 to lift the side plate 4 and the transparent barrel cover 5. After the transparent barrel cover 5 is lifted, it is convenient for the operator to pour the abrasive material and the housing into the barrel body 1. When polishing the drum brake housing in the barrel body 1, the side plate 4 is lowered to cover the transparent barrel cover 5 on the barrel body 1, which can prevent the abrasive material from splashing out during the polishing of the housing and prevent dust from flying.

[0039] The compression spring 603 pushes the latch rod 602 to move through the limit ring 604, so that one end of it is inserted into the corresponding locking hole 11, which can fix the side plate 4 and the transparent barrel cover 5 that move up and down. The limit block 605 can prevent the latch rod 602 from falling out of the cylinder body 601.

[0040] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of protection required by the present invention.
