[0002] A grinding device is a specialized piece of equipment used for grinding and polishing in the manufacturing process of miniature bearings. Its main function is to ensure the precision, smoothness, and performance of the bearings by grinding, polishing, or removing minute surface defects.

[0003] When using a grinder to process miniature bearings, the miniature bearing is placed on two limit rods for positioning. Then, the motor on the grinder is started to drive the grinding roller to rotate. At the same time, the miniature bearing is manually pushed on the limit rods towards the grinding roller, so that the grinding roller can grind its surface. During the grinding process of the miniature bearing, debris is generated. If the debris is not cleaned in time, it may enter the inside of the grinder, affecting the stability of the equipment. At the same time, if it is scattered everywhere, it is inconvenient for later cleaning and maintenance, which can easily affect the use of the grinder and reduce processing efficiency. Utility Model Content

The output end of the motors 6 is fixedly installed on one end of the grinding rollers 5 via a coupling. A cleaning device 2 is provided on one side of the grinding machine 1. The cleaning device 2 can install a dust suction hood 22 directly below the grinding rollers 5, and then use a fan 24 as a drive to suck the debris generated during the grinding process into the conveying pipe 23 and the collection mechanism 25 for collection, thereby achieving the effect of cleaning. When using the grinder 1 to process the miniature bearing, the miniature bearing is placed on two limit rods 4 for positioning. Then, the motor 6 on the grinder 1 is started to drive the grinding roller 5 to rotate. At the same time, the miniature bearing is manually pushed on the limit rods 4 to move towards the grinding roller 5, so that the grinding roller 5 can grind its surface. During the grinding process, the cleaning device 2 is activated to clean up the debris generated during grinding in a timely manner, so that it does not easily enter the interior of the grinder 1, improving the operational stability of the equipment. It also avoids the situation of debris splashing everywhere, making it easier to clean and maintain the grinder 1, facilitating its later use and improving processing efficiency.

[0032] Figure 2 and Figure 3The cleaning device 2 shown includes a bracket 21, wherein a detachable mechanism 26 is provided between the two sides of the bracket 21 and one side of the grinder 1; a dust hood 22, wherein both sides of the dust hood 22 are fixedly installed on one side of the bracket 21 and located directly below the two grinding rollers 5; a fan 24, wherein the outer surface of the fan 24 is fixedly installed on one side of the bracket 21; a conveying pipe 23, wherein both ends of the conveying pipe 23 are respectively installed through the bottom of the dust hood 22 and the inlet of the fan 24; and a collection mechanism 25, wherein the collection mechanism 25 is located between the outlet of the fan 24 and one side of the bracket 21 for collecting and processing the debris conveyed by the conveying pipe 23. First, the bracket 21 is fixedly installed on the grinder 1 using the detachable mechanism 26. Then, when the grinding roller 5 is grinding the surface of the miniature bearing, the fan 24 can be started to suck the debris into the inner wall of the conveying pipe 23 through the dust suction hood 22. The debris is then transported to the collection mechanism 25 for collection, which cleans up the debris generated during grinding in a timely manner, making it less likely to enter the grinder 1 and improving the operational stability of the equipment. At the same time, it avoids the situation of debris splashing everywhere, making it easier to clean and maintain the grinder 1, facilitating the later use of the grinder 1 and improving processing efficiency.

[0033] Figure 2 and Figure 3 The collection mechanism 25 shown includes a collection box 251, with the outlet of the fan 24 installed through the top of the collection box 251, and the bottom of the inner wall of the collection box 251 being hollow; a hollow drawer 253, which is inserted into the inner wall of the collection box 251; and a limiting block 252, one end of which is rotatably installed on one side of the collection box 251, and the other side abuts against one side of the hollow drawer 253. When using the cleaning device 2, the hollow drawer 253 can be inserted into the collection box 251 first, and then the limiting block 252 can be rotated to a certain angle until one side abuts against one side of the hollow drawer 253, thus fixing it inside the collection box 251. When the conveying pipe 23 conveys the debris into the collection box 251, air will be discharged from the bottom hollow of the collection box 251 and the hollow drawer 253, while the debris will be filtered down and collected for later unified treatment. The collecting mechanism 25 also includes a handle block 254, with both ends of the handle block 254 fixedly installed on one side of the openwork drawer 253. By setting the handle block 254, the contact area on one side of the openwork drawer 253 can be increased, making it easier to manually grasp and pick up one side.

[0034] Figure 2 and Figure 3The detachable mechanism 26 shown includes two screw-hole blocks 262, one side of which is fixedly installed on one side of the grinder 1. The bracket 21 has threaded holes 261 on both sides, and is inserted between the two screw-hole blocks 262. Two bolts 263 are also included, one end of which is screwed into the threaded hole 261 and the inner wall of the screw-hole block 262. When the replaced bracket 21 needs to be installed on the grinder 1 for cleaning, the bracket 21 can be inserted between the two screw-hole blocks 262, and the dust cover 22 can be positioned directly below the two grinding rollers 5, so that one side of the bracket 21 abuts against one side of the grinder 1. Then, the bolts 263 are screwed into the inner wall of the screw-hole block 262 and the threaded hole 261 and tightened.

A connecting rope 264 is fixedly installed on one side of the bolt 263, and one end of the connecting rope 264 is fixedly installed on one side of the threaded hole block 262. By setting the connecting rope 264, the bolt 263 can be limited to one side of the threaded hole block 262, so that it is not easy to lose it after being pulled out of the threaded hole block 262 and the threaded hole 261.

[0035] Figure 4 The pushing device 3 shown includes an electric telescopic rod 31, one side of which is fixedly mounted on one side of the grinder 1. A push plate 32 is fixedly mounted on one end of the output rod of the electric telescopic rod 31, and a rubber block 34 is fixedly mounted on one side of the push plate 32. When the miniature bearing is placed on the limiting rod 4 for limiting grinding, the electric telescopic rod 31 can be activated to drive the push plate 32 to one end until the rubber block 34 on one side abuts against one side of the miniature bearing, pushing it towards the grinding roller 5, facilitating its transport to the grinding roller 5 for grinding. This operation avoids accidental injury caused by manual pushing, reduces safety hazards during grinding, and facilitates grinding processing. Several reinforcing rods 33 are fixedly mounted on the outer surface of the output rod of the electric telescopic rod 31, one side of which is fixedly mounted on one side of the push plate 32. By setting the reinforcing rods 33, the connection area between the output rod of the electric telescopic rod 31 and the push plate 32 can be increased, making the connection more secure and stable.

[0036] Working principle: When processing the miniature bearing using the grinder 1, first insert the bracket 21 between the two screw hole blocks 262, and place the dust collection cover 22 directly below the two grinding rollers 5, so that one side of the bracket 21 abuts against one side of the grinder 1. Then, screw the bolt 263 into the inner wall of the screw hole block 262 and the threaded hole 261 and tighten it. This will fix the bracket 21 on one side of the grinder 1. Insert the hollow drawer 253 into the inside of the collection box 251, and then rotate the limiting block 252 to a certain angle until one side abuts against one side of the hollow drawer 253, fixing it inside the collection box 251. Then, place the miniature bearing on the two limiting rods 4 for limiting. Then, start the motor 6 on the grinder 1 to drive the grinding rollers 5 to rotate, and simultaneously manually... The miniature bearing is moved along the limit rod 4 towards the grinding roller 5, facilitating the grinding roller 5 to grind its surface. While the grinding roller 5 is grinding the surface of the miniature bearing, the fan 24 can be started to suck the debris into the inner wall of the conveying pipe 23 through the dust suction hood 22. After the conveying pipe 23 conveys the debris into the collection box 251, the air will be discharged from the bottom of the collection box 251 and the hollow drawer 253, while the debris will be filtered down and collected for later unified processing. Timely cleaning of the debris generated during grinding prevents it from entering the grinding machine 1, improving the operational stability of the equipment. It also avoids the situation of debris splashing everywhere, making it easier to clean and maintain the grinding machine 1, facilitating its later use and improving processing efficiency.

[0037] When placing the miniature bearing on the limiting rod 4 for limiting grinding, the electric telescopic rod 31 can be activated to drive the push plate 32 to one end until the rubber block 34 on one side abuts against one side of the miniature bearing, pushing it towards the grinding roller 5, so as to facilitate its transport to the grinding roller 5 for grinding. This operation can avoid accidental injury caused by manual pushing, reduce safety hazards during grinding, and facilitate grinding processing.

[0038] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model.
