Description

Technical Field

[0001] The utility model relates to the technical field of deburring machines, and particularly relates to a sand belt roller brush deburring machine. Background Art

[0002] A deburring machine is a machining device for grinding and chamfering sheet metal parts. By using grinding parts such as sand belts or roller brushes to grind and chamfer the sheet metal parts, the burrs after processing of the sheet metal parts can be removed and the sheet metal parts can be chamfered, making the edges and corners of the sheet metal parts smoother.

[0003] The existing sand belt roller brush deburring machines mainly include a sand belt mechanism and a roller brush mechanism. Among them, the roller brush mechanism drives the mounting frame to rotate through a revolution motor, and then the motor in the mounting frame drives the roller brush to rotate. For example, a sand belt roller brush deburring machine disclosed in Chinese Patent CN219901606U. For this sand belt roller brush deburring machine, the structural design of the sand belt mechanism and the roller brush mechanism and the positional relationship between the sand belt mechanism and the roller brush mechanism can grind the surface of the product through the sand belt mechanism. However, due to the elastic adjustment of the elastic adjustment component, it can ensure that the oxide skin of the product will not be damaged. Through the roller brush mechanism, the chamfering range of the product can be increased, and the product can be embossed. However, while solving problems, this sand belt roller brush deburring machine has the following defects:

[0004] 1. There are two motors arranged in the mounting frame to drive the four roller brushes below to rotate. Since the first motor and the second motor need to be powered by wires, and both motors need to rotate with the mounting frame, the power supply lines for the first motor and the second motor need to be set with a more precise power supply structure, so it is not convenient for production;

[0005] 2. The self-rotation driving member includes two motors. Since the motors are heavy, the self-rotation driving member is heavy. Therefore, the third motor requires a large power, and the entire roller brush mechanism requires three motors to operate, so it is more power-consuming and has poor energy-saving performance;

[0006] 3. The entire roller brush mechanism includes three motors. Since the cost of the motors is high, the overall cost is high and it is not convenient to promote. Summary of the Utility Model

[0007] The purpose of the utility model aims to solve at least one of the technical defects described in the background art.

[0008] For this reason, an object of the utility model is to provide a sand belt roller brush deburring machine, aiming to solve the problems of inconvenient production, poor energy-saving performance and high cost of the existing sand belt roller brush deburring machines.

[0009] To achieve the above object, an embodiment of one aspect of the present utility model provides a sand belt roller brush deburring machine, which includes a conveyor belt, and a sand belt mechanism and a roller brush mechanism arranged in sequence along the conveying direction of the conveyor belt. The roller brush mechanism includes a lifting frame. A positioning shaft is fixedly connected to the bottom of the lifting frame. A rotating box is rotatably connected to the outer surface of the positioning shaft. Two sleeves are fixedly connected to the outer surface of the rotating box. A driving box is fixedly connected to one end of the sleeve away from the rotating box.

[0010] A first gear disk is fixedly connected to the bottom end of the positioning shaft. A transmission shaft is rotatably connected to the inside of the sleeve. A first gear and a second gear are respectively fixedly connected to both ends of the transmission shaft. A roller shaft is rotatably connected to the inside of the driving box. A second gear disk is fixedly connected to the outer surface of the roller shaft. The first gear meshes with the first gear disk. The second gear meshes with the second gear disk. A roller brush is fixedly installed on the outer surface of the roller shaft.

[0011] Compared with the prior art, the advantages and beneficial effects of the present utility model are as follows:

[0012] 1. By setting a fixed positioning shaft and a first gear disk at the bottom of the positioning shaft, and rotatably connecting the rotating box to the outer surface of the positioning shaft, the rotating box is driven to rotate. The first gear rolls on the surface of the first gear disk, causing the transmission shaft and the second gear to rotate. The rotating second gear then drives the second gear disk to rotate, thereby achieving the purpose of driving the roller brush to rotate. Therefore, there is no need to set a rotatable power supply mechanism, which is convenient for production.

[0013] 2. The rotation of the roller brush depends on the transmission between the first gear disk at the bottom of the positioning shaft, the rotating box, the gears at both ends of the transmission shaft, and the second gear disk on the roller shaft. The overall structure is relatively light in weight, and there is only one driving motor for electrical equipment. Therefore, it is more power-saving and achieves the purpose of energy conservation.

[0014] 3. Two motors are cancelled in the entire roller brush mechanism, and the costs of other structures are relatively low. Therefore, the overall cost is relatively low and it is convenient for popularization.

[0015] The additional aspects and advantages of the present utility model will be partially given in the following description, partially will become obvious from the following description, or will be understood through the practice of the present utility model. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] As Figure 4As shown, a driving cylinder 331 is fixedly connected at the center of the top of the rotating box 33. The driving cylinder 331 is hollow and does not contact the positioning shaft 32. A driven sprocket 332 is fixedly connected to the outer surface of the driving cylinder 331. A driving motor 36 is fixedly installed on one side of the lifting frame 31. A driving sprocket 361 is fixedly connected to the output end of the driving motor 36. The driving sprocket 361 and the driven sprocket 332 are connected by a chain 37. The driving motor 36 can drive the driving cylinder 331 to rotate through the chain 37, thereby achieving the purpose of rotating the rotating box 33.

The structure of the first lifting assembly 7 is exactly the same as that of the second lifting assembly 8, and the liftable screw in the first lifting assembly 7 is connected to the sand belt mechanism 2, which is used to drive the sand belt mechanism 2 to move up and down.

[0031] The working principle of the utility model is as follows: when in use, start the sanding belt mechanism 2 and the roller brush mechanism 3, put the parts to be deburred on the conveyor belt 1, the conveyor belt 1 first conveys the parts to the bottom of the sanding belt mechanism 2, the sanding belt of the sanding belt mechanism 2 rotates the parts for preliminary grinding and deburring, and then conveys the parts to the bottom of the roller brush mechanism 3, the driving motor 36 drives the driving cylinder 331 to rotate through the chain 37, thereby driving the rotating box 33 to rotate, and the rotating box 33 drives the transmission shaft 341 in the sleeve 34 to rotate around the positioning shaft 32, so that the first gear 342 rolls on the surface of the first toothed disc 321, so that the transmission shaft 341 and the second gear 343 rotate, and the rotating second gear 343 drives the second toothed disc 352 to rotate, thereby achieving the purpose of driving the roller brush 353 to rotate, and the rotating roller brush 353 deburrs the parts passing below.
