A clamping and aligning device for processing transmission shaft grooves

Abstract

The invention discloses a clamping alignment device for transmission shaft groove processing and a using method. The clamping alignment device comprises a cover plate (2), an inner adjusting screw (4), a square box (5), a pressing plate (6), a pressing plate screw (7), pressing plate supporting rods (8), an outer adjusting screw (10) and a fastening pin (11), the cover plate (2) is mounted on thesquare box (5), a V-shaped through hole (21) is formed in the middle of the cover plate (2), the end of the inner adjusting screw (4) after penetrating in from one side of the cover plate (2) penetrates out from the side wall of the V-shaped through hole (21), and the outer adjusting screw (10) is mounted at the edge of the upper surface of the cover plate (2) and positioned on the opposite side of the inner adjusting screw (4); the pressing plate supporting rods (8) are symmetrically mounted on two sides of the V-shaped through hole (21), the pressing plate (6) is mounted on the pressing plate supporting rods (8), and the pressing plate screw (7) after penetrating the pressing plate (6) is mounted on the cover plate (2). The clamping alignment device enables a common milling machine to process a transmission shaft groove, so that an expensive multiaxis processing center is not needed.

Description

technical field [0001] The invention relates to a clamping and aligning device. Background technique [0002] The transmission shaft part is the key part in the transmission assembly of the missile weapon, and its machining accuracy is directly related to the flight control accuracy of the missile weapon. Therefore, there are very strict requirements for shape, position and dimensional accuracy, which are mainly reflected in the drive shaft groove. The figure below shows the shape and size requirements of a transmission shaft groove. like figure 1 shown. [0003] In the original milling method of the transmission shaft groove, such as figure 2 As shown, during processing, the pressing part is the pressing surface A, the positioning part is the positioning surface B, and the milling cutter C is vertically processed. The original processing method has the following problems: the transmission shaft is only clamped by a simple pressure plate pressing method, and the shaft ...

AI Technical Summary

Problems solved by technology

The original processing method has the following problems: the transmission shaft is only clamped by a simple pressure plate pressing method, and the shaft part of the transmission shaft is embedded in the tooling, so it is impossible to use the shaft part for tool alignment, and problems such as torsion and movement of the groove end of the transmission shaft are prone to occur during processing , at this time, if the ordinary milling machine is used for processing, the dimensional accuracy cannot be guaranteed, so the multi-axis machining center can only be used to fix the transmission shaft parts, and the clamping error can be corrected by adjusting the work table and the spindle angle; although the processing accuracy can be guaranteed, The equipment cost is high, the occupation of the multi-axis machining center is serious, and the production efficiency is low
