Double-groove bearing super precise grinding machine

Abstract

The invention disclose a double-channel 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 three rollers which are arranged in parallel, every two adjacent rollers form a grinding service position; the grinding device includes two channel grinding devices respectively corresponding to the two grinding service positions, so as to process channels on the workpieces in the grinding service positions; the material loading device includes a portal frame arranged 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 one workpiece to one of the channel grinding service positions, and the second manipulator is used for sending the workpiece from one of the channel grinding service positions to the other channel grinding service position. The double-channel 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 double channel 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 double channel bearing used for water pumps, in which steel balls are used to cooperate between the channel and the shaft, so the roughness of the channel surface, the roundness of the channel, etc. are the key points of 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 the worker holds the workpiece on the station for grinding. But this kind of manual equipment has some ob...

AI Technical Summary

Problems solved by technology

But this kind of manual equipment has some obvious shortcomings. First, it is a 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 have slow beats and low efficiency; moreover, the grooves of workpieces manually ultra-finishing are relatively rough (higher roughness), the roundness of the grooves is not high, and the groove diameter difference of the grooves is unstable. Resulting in low quality; finally, the manually controlled ultra-fine grinding machine has no external protection and is not safe enough
