Single groove single race bearing super precise grinding machine

Abstract

The invention disclose a single-channel single-race bearing superfine grinding machine including a machine frame with an operating desk, as well as a workpiece seat, a grinding device and a material loading device which are arranged on the operating desk, wherein the workpiece seat includes four rollers which are arranged by groups of two, so as to form a race grinding service position and a channel grinding service position; the grinding device includes a race grinding device which is used for race processing and arranged corresponding to the race grinding service position, and a channel grinding device which is used for channel processing and arranged corresponding to the channel grinding service position; the material loading device includes a portal frame arranged athwart above the workpiece seat, first and second traverse motion mechanisms arranged on the portal frame, as well as first and second manipulators which are respectively connected with the first and the second traverse motion mechanisms, wherein the first manipulator is used for sending a workpiece to the race grinding service position, and the second manipulator is used for sending the workpiece from the race grinding service position to the channel grinding service position. The single-channel single-race bearing superfine grinding machine has the advantages of fully automatic running, precise processing and so on.

Description

technical field [0001] The invention relates to a bearing grinding machine, in particular to an ultra-fine grinding machine for single channel and single raceway bearings. Background technique [0002] Bearings are widely used in the field of machinery, and with the advancement of mechanical technology, the precision requirements for bearings are increasing day by day. The precision of bearings and shafts is directly related to the performance and life of mechanical systems. For example, a single-channel single-roller bearing for water pumps, in which steel balls are used to cooperate between the channel and the shaft, and needle rollers are used to cooperate between the raceway and the shaft, so the surface roughness of the channel and the roundness of the channel Degree, etc. is the key to processing. [0003] At present, a kind of manual superfinishing machine is used to process this type of bearing, which is generally provided with at least one manual station, and then...

AI Technical Summary

Problems solved by technology

This kind of manual equipment has some obvious disadvantages. The first is the problem of efficiency. Manual equipment needs manual loading and unloading, which takes a lot of time, and one person can only operate one piece of equipment; The two steps of ultra-finishing and ultra-finishing are slow in pace and low in efficiency, and the two processes of super-finishing the groove and raceway of the workpiece need to be processed separately by two devices, which is very inconvenient; moreover, the groove of the workpiece for manual super-finishing It is relatively rough (higher roughness), the roundness of the channel is not high, and the channel diameter difference is unstable, resulting in low quality; finally, the manually controlled ultra-fine grinding machine has no external protection and is not safe enough
