The fixture is characterized in that the bottom surface of a fixture chassis (1) is provided with a connecting positioning rabbet (1-6); a technological central hole (1-4), machine tool connecting holes (1-3), press-plate connecting holes (1-2), a front cover boss connecting trough (1-5), a positioning boss (1-1) and a gap positioning pin (2) are sequentially arranged on the fixture chassis (1), the gap positioning pin (2) is provided with a gap (2-1), the three machine connecting holes (1-3) are uniformly distributed along a 120-degree circumference, the four press-plate connecting holes (1-2) are symmetrically arranged in an up-and-down mode on the right side of the technological central hole (1-4), the positioning boss (1-1) and the former-cover boss connecting trough (1-5) are arranged concentrically, and the positioning boss (1-1) is arranged in the center of the former-cover boss connecting trough (1-5). The bearing hole machining fixture for the auxiliary shafts of the front covers is simple in structure and convenient to clamp, and can be used for reducing the labor intensity of workers.
Description
Technical field
The utility model belongs to the mechanical processing technique equipment, and particularly a kind of protecgulum is from the axle bearing hole processing clamp.
Background technology
From axle bearing hole turning process, because gear pump protecgulum profile more complicated, the positioning difficulty that is installed is big at the gear pump protecgulum; Need many sleeve clamps to be installed; Increase working strength of workers, wasted in a large number and be installed man-hour, also be difficult to guarantee the quality and the production efficiency of processing simultaneously.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned technical deficiency, provides a kind of time saving and energy saving, can enhance productivity, and the protecgulum that guarantees crudy is from the axle bearing hole processing clamp.
The technical scheme that the utility model technical solution problem adopts is: protecgulum comprises anchor clamps chassis, gap alignment pin from the axle bearing hole processing clamp; Be characterized in that the anchor clamps undersurface of bottom disc is provided with one and connects positioning spigot; Be respectively equipped with technology centre bore, lathe connecting hole, pressing plate connecting hole, protecgulum boss link slot, positioning boss, gap alignment pin above the jig chassis; The gap alignment pin is provided with gap, and three lathe connecting holes are 120 degree circumference uniform distributions, and four pressing plate connecting holes are positioned at upper and lower being symmetrical set in technology centre bore right side; Positioning boss and protecgulum boss link slot are provided with one heart, and positioning boss places protecgulum boss link slot center.
The beneficial effect of the utility model is: protecgulum is simple in structure from the axle bearing hole processing clamp; Convenient mounting and clamping can alleviate labor strength, improves the quality and the production efficiency of protecgulum turning processing from the axle bearing hole; Not only save time but also laborsaving, be suitable for the batch process of enterprise.
