Milling cutting installing and clamping tooling for end surface of circular arc-shaped clamp hoop

Abstract

The invention discloses a milling cutting installing and clamping tooling for the end surface of a circular arc-shaped clamp hoop. The problem of installing clamping fixation during the milling and cutting on the end surface of the circular arc-shaped clamp hoop is solved. The tooling comprises an installing and clamping base (1) and an arc-shaped workpiece (9) with concave grooves, wherein a door-shaped frame (12) is arranged at the left end of the installing and clamping base (1); an L-shaped workpiece top end pressing block (16) is arranged on the top beam of the door-shaped beam (12); a right lower end stop block (21) is arranged at the right end of the installing and clamping base (1); a right lower end baffle plate (20) is arranged at the side surface of the right lower end of the installing and clamping base (1); a workpiece upper end positioning pin (11) is inserted and connected between the workpiece positioning through hole (10) and the positioning long strip groove (8); thearc-shaped surface (2) arranged on the installing and clamping base (1) and the arc-shaped workpiece (9) with concave grooves have the completely identical radian, so that the arc-shaped bottom surface of the arc-shaped workpiece (9) with concave grooves and the arc-shaped surface (2) are completely attached. The universality of the tooling is high; the tooling is particularly suitable for mass processing.

Description

technical field [0001] The invention relates to a milling and clamping tool, in particular to a clamping tool for fixing workpieces used when milling the end face of a circular-arc clamp section. Background technique [0002] The clamp is a circular arc part, which is polished by the fitter to the size required by the process when processing the end faces of the two ends. Alignment, the sharp corners of the end face are often worn during operation, so that the scrap rate of this kind of parts remains high. When processing circular arc parts, the entire circle is cut by electric spark, and then the fitter manually grinds the cut surface to the required size. When grinding, the part surface is easy to be damaged by the clamping of the part, and the processing dimensional accuracy is not easy to guarantee. If the end face processing process of arc parts is changed from fitter polishing to milling milling, it can meet higher technological requirements, but because the clamp is ...

Problems solved by technology

When processing arc parts, the whole circle is cut by electric spark, and then the fitter manually grinds the cutting surface to the required size. When grinding, the part surface is easy to be damaged by the clamping of the part, and the processing dimensional accuracy is not easy to guarantee

If the end face processing process of arc parts is changed from fitter polishing to milling milling, it can meet higher technological requirements, but because the clamp is in the shape of an arc, it is easy to appear up and down, left and right, and back and forth when clamping. How to overcome milling These problems in processing are difficult problems that need to be solved in on-site processing
