Dual-cylinder carriage and combined oilstone clamp mechanism of bearing roller super-precision grinding machine

Abstract

The invention relates to the technical field of grinding machines, in particular to a dual-cylinder carriage and a combined oilstone mechanism of a bearing roller super-precision grinding machine, which are characterized in that: the dual-cylinder carriage and the combined oilstone clamp mechanism are arranged on the super-precision grinding machine; an oscillation carriage pair (4) is arranged on a beam of the super-precision grinding machine; the back of an upper-lower carriage pair (2) is provided with a pair of linear guides connected with the oscillation carriage pair (4); the oscillation carriage pair (4) is provided with a fast feeding cylinder pair (1) which is provided with a piston rod; the piston rod is provided and connected with the upper-lower carriage pair (2); the upper-lower carriage pair (2) is provided with a plurality of working feeding cylinder pairs (3); and a combined oilstone clamp is arranged below the working feeding cylinder pairs (3). Compared with the prior art, the dual-cylinder carriage and the combined oilstone clamp mechanism substantially avoid the breakage and crack of oilstones causing frequent shutdown, exchange the oilstones fast and conveniently and prolong the service life of the oilstones so as to make persistent and smooth an automatic flow line production process, remarkably improve the production efficiency and reduce the production cost.

Description

technical field [0001] The invention relates to the technical field of grinding machines, in particular to a double-cylinder drag plate and a combined oilstone clamping mechanism of a bearing roller superfine grinding machine. Background technique [0002] Superfine grinding machine (hereinafter referred to as machine tool) is a special production equipment widely used in the bearing industry, mainly used to improve the roughness level of the surface of bearing rolling element parts. Its working principle is that the workpiece performs rotary motion and axial linear motion under the action of a pair of guide rollers on the machine tool, and a group of oil stone sheets (generally 4-8 pieces) are pressed on the circular surface of the workpiece to perform axial high-frequency oscillation motion. Thus, the micro-edge cutting of the surface of the workpiece is formed, and the precision level of the workpiece is improved. [0003] Each piece of oil stone in the existing machine ...

AI Technical Summary

Problems solved by technology

[0005] The whetstone clamp of the existing machine tool generally clamps 1 / 4 of the length of the whetstone sheet, and its 3 / 4 protruding part has no protection, and the workpiece will have a certain deflection on the whetstone during work, and the whetstone is often broken

In addition, when the cylinder goes down, the oil stone directly hits the workpiece, which is very easy to cause fragmentation

[0006] B clamping oil stone is time-consuming and labor-intensive

[0007] The existing machine tool oil stone clamp is clamped by two steel plates with bolts. If the clamp is too tight during installation, the oil stone will be crushed; if it is too loose, the grinding function will fail.

And it is quite time-consuming and laborious to install

[0008] The utilization rate of C oilstone is not high

[0009] In addition to the above factors, even if a piece of oilstone works normally, its utilization rate is only about 60%.

[0010] The above-mentioned shortcomings have caused the entire machine tool to be shut down frequently to replace the oil stone, thus affecting the production efficiency
