Abstract

The invention discloses a kind of precise cross-shaped slot clamp for machining, the key of angular positioning key upper end and the straight trough of workpiece to be machined match, and the wide T-slot notch with base plate of the seat of lower end matches, and the long diameter with workpiece to be machined matches；Mesoporous positioning plate centre bit is equipped with the through-hole that the diameter of diameter always and workpiece to be machined matches, and there are also the upper surface of matching with T-slot notch, symmetrical there are two the strip slots of mounting hole on mesoporous positioning plate；There are elongate holes on pressing plate；Angular positioning key is placed in the T-slot of base plate, mesoporous positioning sleeve-board outside angular positioning key and is fixed on base plate, workpiece to be machined is placed in the through-hole of mesoporous positioning plate, and straight trough is connected on the key of angular positioning key upper end, and pressing plate is crimped on the both ends of workpiece to be machined.Using present clip by workpiece it is fixed after, the positioned center of milling cutter can very simple one-pass molding crescent, accurate positioning, machining accuracy is high, is nearly free from waste product.

Description

Precise cross-shaped slot clamp for machining
Technical field
The present invention relates to a kind of precise cross-shaped slot clamp for machining.
Background technique
There is a kind of of large quantities, dedicated " aircraft oil cylinder of the demanding aviation of technical conditions small in size in aeronautical product manufacture Upper fastening bolt " processes mutually perpendicular one directly in two end faces for wanting workpieces processing 4 as depicted in figs. 1 and 2 Slot 14 and a crescent 13 are in cross state, and have stringent position degree and size requirement.Existing processing method is in work Straight trough is processed on part first, then blocks workpiece with scroll chuck, the processed crescent line of rabbet joint is drawn on its other end, Crescent is processed according to the line of rabbet joint drawn with cutter, cutter is not easy to position, it is easy to waste product occurs, general 2/3 workpiece is given up Fall, processing efficiency and its low, processing cost height.
Summary of the invention
The object of the invention is to solve the above-mentioned problems in the prior art, a kind of precise cross-shaped slot processed clip is provided Tool, using the fixture by workpiece it is fixed after, the positioned center of milling cutter can very simple one-pass molding crescent, positioning is quasi- Really, machining accuracy is high, is nearly free from waste product.
To achieve the above object, the technical solution of the invention is as follows: a kind of precise cross-shaped slot clamp for machining comprising base Plinth plate, angular positioning key, mesoporous positioning plate and two pressure plates；The center of base plate is provided with that notch is narrow, lower wide T-slot；Angle The straight trough of key and workpiece to be machined to positioning key upper end matches, the wide T-slot notch phase with base plate of the seat of lower end Match, the long diameter with workpiece to be machined matches；Mesoporous positioning plate centre bit is equipped with the diameter phase of diameter and workpiece to be machined always Matched through-hole, there are also the upper surface of matching with T-slot notch, symmetrical there are two the strips of mounting hole on mesoporous positioning plate Shape slot；There are elongate holes on pressing plate；In use, angular positioning key is placed in the T-slot of base plate, mesoporous positions sleeve-board angular Positioning key is outer and is fixed on base plate, and the center line of through-hole thereon is overlapped with the vertical centerline of angular positioning key, is added Work workpiece is placed in the through-hole of mesoporous positioning plate, and straight trough is connected on the key of angular positioning key upper end, and pressing plate, which is crimped on, to be added The both ends of work workpiece, and be fixed on base plate；There is the limit to match with the height of workpiece to be machined between pressing plate and base plate Position bar.
After being fixed workpiece using present clip, the positioned center of milling cutter can very simple one-pass molding crescent moon Slot, accurate positioning, machining accuracy is high, is nearly free from waste product.

Specific embodiment
The present invention will be further described in the following with reference to the drawings and specific embodiments.
As shown in Fig. 3, Fig. 4 and Fig. 5, the present embodiment includes that it includes base plate 9, angular positioning key 10, mesoporous positioning plate 5 With two pressure plates 3,7.The center of base plate 9 is provided with that notch is narrow, lower wide T-slot 11.The key 12 of angular 10 upper end of positioning key Match with the straight trough 14 of workpiece to be machined 4, wide 11 notch of T-slot with base plate 9 of the seat of lower end matches, and grows and is added The diameter of work workpiece 4 matches.The diameter that 5 centre bit of mesoporous positioning plate is equipped with diameter and workpiece to be machined 4 always matches logical Hole 15, there are also the upper surface of matching with 11 notch of T-slot, symmetrical there are two the strips of mounting hole on mesoporous positioning plate 5 Slot.There are elongate holes on pressing plate 3 or 7.In use, angular positioning key 10 is placed in the T-slot 11 of base plate 9, mesoporous positioning plate 5 It covers outer in angular positioning key 10 and is fixed on base plate 9, the center line of through-hole 15 thereon is vertical with angular positioning key 10 Center line is overlapped, and workpiece to be machined 4 is placed in the through-hole 15 of mesoporous positioning plate, and straight trough 14 is connected to angular 10 upper end of positioning key Key 12 on, pressing plate 3,7 is crimped on the both ends of workpiece to be machined 4, and is fixed on base plate 9 by bolt 2,6.Pressing plate 3,7 with There is the gag lever post 1,8 to match with the height of workpiece to be machined 4 between base plate 9.
Above-described embodiment be only it is preferred and illustrative, those skilled in the art can do according to the spirit of this patent Same technological improvement, these are all covered by the protection scope of this patent.
