A blade clamping and centering adjustment device for an indexable blade peripheral grinder

Abstract

A blade clamping centering adjusting device of an indexable insert periphery grinding machine is characterized by comprising a V-shaped locating block, a vertical moving block, a horizontal moving block, a guide fixed block, a flange base, a horizontal differential screw, a vertical differential screw, a wedge block A, a wedge block B, a guide post and a compression spring. The V-shaped locating block is installed on the vertical moving block, the horizontal moving block is connected with the flange base through a dovetail groove in the horizontal moving block and the wedge block B, the guide fixed block is connected with the flange base through a dovetail groove in the guide fixed block and the wedge block A, the vertical differential screw is connected with the vertical moving block and the horizontal moving block, and the horizontal differential screw is connected with the guide fixed block and the horizontal moving block. The blade clamping centering adjusting device is simple in structure, small in size and low in manufacturing cost, does not rely on operation workers' experience level in use, does not need to be by means of other auxiliary tools, is high in efficiency and centering precision, greatly shortens processing auxiliary time and improves processing efficiency and precision of an indexable insert.

Description

technical field [0001] The invention relates to a blade clamping and centering adjustment device of an indexable blade peripheral grinding machine. Background technique [0002] The centering adjustment of the indexable insert clamping is an essential process before the peripheral grinding of the indexable insert. The less the centering adjustment time, the less the total auxiliary man-hours, which can effectively improve the processing efficiency of the peripheral grinding machine; The higher the accuracy of center adjustment, the smaller the probability of interference during processing, and the higher the processing accuracy of the blade. [0003] In existing processing equipment, when centering and adjusting the clamping of indexable inserts, methods such as centering mandrel, auxiliary tooling and direct adjustment are usually used. The main disadvantages are: [0004] First, when using the centering mandrel to adjust the centering of the clamping of the indexable blad...

AI Technical Summary

Problems solved by technology

When using an external prism, first calibrate the centering externally, and then exchange it to the machine tool. Although this method is convenient for adjustment, the centering accuracy will decrease after conversion, and the external prism needs to be purchased additionally. , the cost is high; adjustment by means of the gauge block and the positioning surface of the box itself requires frequent measurement, disassembly, and adjustment of the horizontal and vertical directions by the prism, which takes a lot of auxiliary time

[0006] Third, direct adjustment refers to the centering adjustment of the indexable insert clamping by the processing workers with bare hands based on experience. This method is dominated by subjective factors and mainly depends on the chirality of the workers. The randomness is very large, and the centering adjustment time cannot be adjusted control
