Description

Technical Field

[0001] The utility model relates to the technical field of superfinishing machine feeding, and specifically to a superfinishing machine transmission mechanism for bearing preparation. Background Art

[0002] Superfinishing is the finishing process of the finished surface using a fine-grained oilstone installed on a vibrating head. Superfinishing is generally arranged to be carried out after the fine grinding process. Its machining allowance is only a few microns. It is suitable for machining the outer circle, inner circle, plane, groove surface and spherical surface of crankshafts, rollers, bearing rings and various precision parts. Superfinishing machine is a kind of precision equipment for this kind of processing. With a low pressure, the oilstone is pressed against the rotating workpiece to form a surface contact state. At the same time, the oilstone makes a high-frequency axial vibration to finely grind the surface of the workpiece. Superfinishing machine can greatly improve the roughness in a short time. Since it is processed under low pressure, the surface structure of the workpiece does not change abnormally, and the surface metamorphic layer generated during the grinding or cutting process can be removed or mostly removed. And because the oilstone and the workpiece are in surface contact and automatically imitate, it can remove the surface ripples that are easy to appear in the grinding process, thereby improving the roundness.

[0003] A Chinese patent discloses a transmission mechanism for a superfinishing machine, with the publication number CN 205325467 U. The article proposes "a driving device, a transmission seat, a motion mechanism and a fixed seat for fixing the swing mechanism of the superfinishing machine, wherein the driving device is mounted on the transmission seat, the motion mechanism is movably mounted in the transmission seat, the input end of the motion mechanism is connected to the driving device, and the output end of the motion mechanism is connected to the fixed seat. The cylinder is mounted on the fixing device, the fixing device is fixedly mounted on the transmission seat, the output shaft end of the piston rod of the cylinder is connected to the rod end bearing, and the rod end bearing is connected to the motion mechanism through a connecting piece. The guide shaft passes through the transmission seat and is parallel to the motion shaft, and the guide shaft arranged in the guide shaft and the transmission seat A linear bearing is installed between the holes, and one end of the guide shaft is connected to the fixed seat. After adopting this technology, the transmission mechanism of the superfinishing machine according to the embodiment of the utility model can accurately drive the swing mechanism of the superfinishing machine and the oil stone installed thereon, so that the oil stone can accurately superfinish the inner ring or outer ring of the bearing, thereby improving the performance of the superfinishing machine. ", but in the prior art, the loading and unloading of the superfinishing machine can be completed either manually or by two sets of mechanisms, which will increase the production cost and reduce the work efficiency. Therefore, it is necessary to design a transmission mechanism of a superfinishing machine for bearing preparation. Utility Model Content

When the first group of bearings 7 touches the sensor on the back of the baffle at the top of the left conveyor belt body 6, the left conveyor belt body 6 will stop. The center of the bearing 7 blocked by the baffle at the top of the left conveyor belt body 6 is located on the same straight line as the rotating shaft 9, and a groove matching the bearing 7 is provided on the top of the rotating shaft 9. Because the center of the bearing 7 blocked by the baffle at the top of the left conveyor belt body 6 is located on the same straight line as the rotating shaft 9, and a groove matching the bearing 7 is provided on the top of the rotating shaft 9, the bearing 7 can be transported to the top of the two groups of rotating shafts 9 through the clamping mechanism 5 and embedded in the top of the rotating shaft 9.
