Description

[Technical field]

[0001] The invention relates to the technical field of bearings, in particular to the technical field of a bearing processing lathe with a cooling function. [Background technology]

[0002] Bearings, which usually include an outer ring, an inner ring, rolling elements and a cage, are an important component in contemporary mechanical equipment. They are mainly used to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. The bearing manufacturing process includes processes such as cutting bearing rings and pressing balls. After the raw materials are cut into bearing ring blanks, a certain amount of burrs will be left on the cut of the bearing ring blank, which needs to be removed. The existing bearing burr removal process usually uses a file to manually check and remove them one by one, which is inefficient and has high labor costs. The inner and outer rings of the bearing will be in constant contact with the rolling balls during the working process. If the roughness is too large, it will cause a large friction force during the rotation process, which will affect the smoothness of the bearing rotation on the one hand and shorten the service life of the bearing on the other hand. Therefore, grinding is required to ensure a certain smoothness. However, the existing grinding device has a relatively cumbersome process for fixing the bearing ring, and can only grind a single bearing ring at a time. Therefore, the bearing ring needs to be manually removed and installed several times in the multi-pass grinding process, which is inefficient. [Summary of the invention]

[0017] Working process of the present invention:

[0018] There are two sets of positioning fixtures 4 and they are arranged front and back on the top surface of the turntable 2. Each set of positioning fixtures 4 has three sets of clamps and the angle between them is 120°. The discharge end of the vibration feeder is above the center of the positioning fixture 4 located at the front side.

[0019] During the operation of the burr removal unit, when the vibration feeder delivers the bearing ring to be processed and makes it fall between the arc plates 42 of the three sets of clamps, the first cylinder 41 pushes the arc plates 42 to move toward the center of the bearing ring clamping area, thereby clamping the bearing ring to be processed. Subsequently, the first motor 21 controls the disc 22 to rotate 180° counterclockwise, so that the bearing ring to be processed moves under the file 3. Then, the second cylinder 33 controls the knife body 36 to descend through the telescopic rod, and the second motor 34 drives the knife body 36 to rotate around its output shaft, thereby scraping off the burrs along the inner wall circumference of the bearing ring to be processed. Next, the first motor 21 controls the disc body 22 to rotate 180° counterclockwise, wherein the first cylinders 41 of the two groups of clamps pull the arc plate 42 to move away from the center of the bearing ring clamping area to loosen the deburred bearing ring, and the first cylinder 41 of the remaining group of clamps pushes the arc plate 42 to push the deburred bearing ring from the top surface of the disc body 22 into the feed channel 9, and then the three groups of clamps return to their original positions to clamp the next bearing ring to be processed conveyed by the vibrating feeder, and so on.

[0020] During the operation of the grinding unit, first, the fourth cylinder 73 pushes the rubber pressing plate 75 downward through the telescopic rod, and presses down the top of several bearing rings to be processed arranged in the material transfer channel. Then, the fifth cylinder 81 pushes the grinding wheel 85 upward, and the third motor 84 drives the grinding wheel 85 to rotate, so that several grinding wheels 85 with different roughness pass through the through hole 612 respectively and grind the inner wall of the bearing ring. After the grinding is completed, the presser 7 and the grinding wheel 8 return to their original positions. After a new bearing ring to be processed enters the material transfer channel from one side of the guide plate 6 along the feed channel 9, the original bearing ring to be processed moves to the other side by the distance of one bearing ring, and the bearing ring at the end of the other side is pushed away from the guide plate 6. This reciprocating process causes the bearing ring to gradually move along the material transfer channel, and finally leave the guide plate 6 after being polished by the grinding wheels 85 with different roughnesses in turn.

[0021] During this period, the water pump inputs water into the curved plate 42 and the side plate 62 respectively through the water outlet 111 of the water tank 11 along the rubber hose from the first water receiving pipe 421 and the second water receiving pipe 623 at one end of the water flow channel, and then flows out from the first water receiving pipe 421 and the second water receiving pipe 623 at the other end of the water flow channel and flows back into the water tank 11 through the return port 113, so as to achieve cooling during the deburring and grinding process. The cooling water can be replaced through the water injection port 114 and the drain port 112 before and after the work is completed.

[0022] The present invention arranges a plurality of groups of positioning tools on a turntable to fix the bearing ring, and utilizes the mutual cooperation between a plurality of groups of clampers in the positioning tools to achieve the work of clamping, loosening and pushing the bearing ring; arranges a file on one of the groups of positioning tools, and utilizes a rotating blade to scrape off burrs on the inner wall of the bearing ring along the circumference, which is fast and efficient; forms a material transfer channel for the movement of the bearing ring to be processed through two side plates, and utilizes a new bearing ring entering the material transfer channel to push the original bearing ring to move along the material transfer channel, so that it is polished in sequence by grinding wheels with different roughness; utilizes a fourth cylinder to push a rubber pressure plate to complete the downward pressing action, squeezes and restricts the movement of the bearing ring from the upper side, so as to ensure the progress of the polishing process; utilizes circulating cooling water to absorb the heat generated during the working process, so as to cool the arc plate and the side plate.

[0023] The above embodiments are intended to illustrate the present invention, not to limit the present invention. Any solution that is a simple transformation of the present invention belongs to the protection scope of the present invention.
