Abstract

The invention discloses a precise processing clamp of cross recesses. A key at the upper end of an angle positioning key is matched with a straight recess of a processed workpiece, the width of a base at the lower end of the angle positioning key is matched with the notch of a T-shaped recess of a basis plate, and the length of the base is matched with the diameter of the processed workpiece; a through hole of which the diameter is matched with that of the processed workpiece, and a strip-shaped recess which is matched with the notch of the T-shaped recess are formed in the center of a center-hole positioning plate, and two mounting holes are symmetrically distributed in the strip-shaped recess; a strip-shaped hole is formed in either of press plates; the angle positioning key is placed in the T-shaped recess of the basis plate, the center-hole positioning plate sleeves the angle positioning key and is fixed on the basis plate, the processed workpiece is placed in the through hole of the center-hole positioning plate, the straight recess is connected to the key at the upper end of the angle positioning key in a clamping manner, and the press plates are connected to both ends of the processed workpiece in a pressing manner. After the workpiece is fixed by adopting the precise processing clamp disclosed by the invention, a milling cutter can simply form a crescent recess in one step along the positioning center, the positioning is correct, the processing precision is high, and almost no waste products are generated.

Description

Precise cross-shaped slot machining fixture
Technical field
The present invention relates to a kind of precise cross-shaped slot machining fixture.
Background technology
In aeronautical product manufacture, there is a kind of batch large, the little technical conditions of volume require high aviation special " fastening bolt on aircraft oil cylinder ", as depicted in figs. 1 and 2, a mutually perpendicular straight trough 14 and a crescent 13 is processed wanting two of processing work 1 end faces, in cross state, and there are strict position degree and dimensional requirement.Existing processing method first processes straight trough on workpiece, workpiece is blocked again with scroll chuck, its other end draws the processed crescent line of rabbet joint, with cutter according to the line of rabbet joint processing crescent drawn, cutter is not easily located, and is easy to occur waste product, and the workpiece of general 2/3 is destroyed, its working (machining) efficiency and low, processing cost is high.
Summary of the invention
Object of the present invention solves the above-mentioned problems in the prior art exactly, provides a kind of precise cross-shaped slot machining fixture, after adopting this fixture that workpiece is fixing, milling cutter just can very simple one-shot forming crescent along its centre of location, its accurate positioning, machining accuracy is high, produces waste product hardly.
For achieving the above object, technical solution of the present invention is: a kind of precise cross-shaped slot machining fixture, and it comprises soleplate, angle positioning key, mesopore location-plate and two block pressur plates; The center of soleplate has narrow, the lower wide T-slot of notch; The key of angle positioning key upper end and the straight trough of workpiece to be machined match, and the seat of its lower end is wide to match with the T-slot notch of soleplate, and diameter that is long and workpiece to be machined matches; The through hole that the diameter that mesopore location-plate centre bit is equipped with footpath and workpiece to be machined always matches and the strip groove being symmetrically distributed with two installing holes above matched with T-slot notch; Pressing plate there is elongate holes; During use, angle positioning key is placed in the T-slot of soleplate, it is outer and be fixed on soleplate that mesopore location-plate is enclosed within angle positioning key, the center line of the through hole on it overlaps with the vertical center line of angle positioning key, workpiece to be machined is placed in the through hole of mesopore location-plate, its straight trough is connected on the key of angle positioning key upper end, and pressing plate is crimped on the two ends of workpiece to be machined, and is fixed on soleplate; The gag lever post matched with the height of workpiece to be machined is had between pressing plate and soleplate.
After adopting fixture of the present invention that workpiece is fixing, milling cutter just can very simple one-shot forming crescent along its centre of location, and its accurate positioning, machining accuracy is high, produces waste product hardly.
