The support assembly of the special universal grinding machine for nuclear power bearing ring processing

Abstract

A support assembly of a universal grinder special for machining nuclear power bearing rings comprises a support head, a casing, a coupler, an adjustable screw propeller, a properller fixing plate and a base. The base is fixed on a workpiece shifting mechanism, the support head is connected with the adjustable screw propeller through the coupler, the connection portion is arranged in the casing, and the propeller fixing plate is installed at one end of the casing to limit the adjustable screw propeller. The adjustable screw propeller is rotated, and the support head is adjusted to abut against a workpiece to be machined. Required eccentric quantity can be adjusted accurately by rotating the adjustable screw propeller (micrometer rotating head) on the support, time required by support adjustment of each time is greatly shortened, and working efficiency can be improved.

Description

technical field [0001] The invention relates to a grinding machine, in particular to a support assembly of a special grinding machine for bearing processing. Background technique [0002] When the CNC grinding machine is processing the ferrule, it is necessary to use the magnetic pole to hold the ferrule. When the magnetic pole (workpiece axis) rotates, it will drive the workpiece to rotate. In addition, at least two points are needed to support the ferrule to ensure that the ferrule can be stable every time. Precisely stay at the processing position. [0003] The important quality indicators in the processing of ferrules include roundness, shape, surface roughness, etc., which are related to the quality of support adjustment. The most critical technical point here is: the axis center of the ferrule and the axis of the magnetic pole (workpiece axis) must have a certain amount of eccentricity to ensure the normal processing of the ferrule. Such as Figure 13 Schematic diagr...

Problems solved by technology

[0005] The quality of the support adjustment will directly affect the key quality of the workpiece. At this stage, it is very unreliable to rely on the operating experience and personal feeling of the operator. This key point of quality cannot be accurately controlled.

Moreover, after the support has been working for a long time, the vibration of the machine tool or other reasons will cause it to loosen, shift, etc. At this time, when the workpiece cannot stay in the expected position, it will cause waste products.

At this time, it is necessary to adjust the support again, which is time-consuming and laborious and uncontrollable

[0006] Disadvantages of the prior art: It is very difficult to adjust: due to the different techniques and experience of the processing personnel, it is difficult to adjust to the correct position

High error rate: Due to the different experiences and abilities of the processing personnel, in the test process of judging whether the adjustment is good, the amount of scrapped workpieces will increase.
