Abstract
The invention discloses a fixture for grinding eccentric inner bores, which comprises a round fixture body clamped on a chuck, screws, fixing blocks, pressure blocks, nuts and compression screws. The center of the top surface of the fixture body is provided with a positioning hole, the periphery of the top end of the round fixture body extends upward to form a retainer ring, the retainer ring and the top surface of the fixture body form a containing groove for holding work pieces, the retainer ring is provided with a plurality of screws axially perpendicular to the retainer ring, and the screws are axially uniformly distributed around the fixture body. The fixing blocks perpendicular to the screws are arranged at the top ends of the screws respectively and provided with the pressure blocks which are capable of sliding vertically, the pressure blocks are perpendicular to the fixing blocks, the compression screws are fixed onto the pressure blocks respectively, the bottom of the containing groove is provided with a plurality of slides, the fixing blocks can slide in the slides, and the other end of each screw is fixed to the outer side of the retainer ring through the nuts. Using the fixture for grinding eccentric inner bores enables grinding to be more convenient and precise and improves machining precision of work pieces.
Description
Technical field
The present invention relates to a kind of anchor clamps, especially a kind of anchor clamps of processing eccentric inner hole belong to machining and use the grip device technical field.
Background technology
During some machine components, have the workpiece that some need process endoporus in processing often, and for some requirement on machining accuracy than higher workpiece, after general roughing is accomplished, all need finish grind processing to this endoporus.But under the situation for some endoporus and workpiece decentraction, processing has just not too made things convenient for, and can only on vertical grinder, process, and it is also pretty troublesome to the heart, and machining accuracy also has certain deviation.
Summary of the invention
Technical problem to above-mentioned existence the objective of the invention is: proposed a kind of convenient correct grinding eccentric inner hole, the anchor clamps that machining accuracy is high.
Technical solution of the present invention is achieved in that a kind of mill eccentric inner hole anchor clamps, comprises clamp body, screw rod, fixed block, briquetting, nut and the housing screw of clamping on chuck; Have locating hole in the end face of said clamp body in the heart; Said clamp body is circular, and has extended upward back-up ring on the top circumference of clamp body; The end face of said back-up ring and clamp body forms the storage tank of a place work piece; Said back-up ring is provided with a plurality of and the screw rod back-up ring axis normal, and screw rod is uniformly distributed with arrangement around the axis of clamp body; The top of said screw rod is equipped with the fixed block perpendicular to screw rod; Be equipped with the briquetting that can slide up and down on the said fixed block; Said briquetting is perpendicular to fixed block, and all is fixed with housing screw on the briquetting; On the bottom surface of said storage tank, have a plurality of chutes; Said fixed block can slide in chute; The other end of said screw rod is fixed on the back-up ring outside through nut.
Preferably, said screw rod is eight.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
Mill eccentric inner hole anchor clamps of the present invention, it is through screw rod and fixed block on the screw rod and briquetting on the back-up ring, and the workpiece clamp that will be positioned at storage tank fastens; And with locating hole location, it is concentric with clamp body to make treating on the workpiece grind endoporus, be placed on clamp body on the chuck after; Workpiece carries out grinding with main axis rotation; Endoporus to be ground like this is concentric with main shaft, and grinding is more accurate, has improved the workpiece machining accuracy.
