Abstract
The invention discloses a clamp for five-star pulling plate milling. The clamp comprises a base plate arranged on a workbench and not less than three chucks arranged on the base plate; a guide rail where the chucks slide is arranged on the base plate, a cavity for containing a five-star pulling plate is defined by the chucks, and not less than two grooves for containing corner angles of the five-star pulling plate are formed between the chucks, and a locking device is arranged on each chuck. End face milling and hole boring can be completed on a vertical milling machine through only one clamp for five-star pulling plate milling, original repeated clamping and positioning of a machined content can be completed through one-time clamping and positioning, the clamp cost is reduced, and the production efficiency and the product quality are improved.
Description
Technical field
The invention belongs to work support, such as the technical field of adjustable centre frame, be specifically related to a kind of five-pointed star plate milling fixture.
Background technology
Five-pointed star plate is a vitals on selector gear, such as Fig. 1, shown in Fig. 2, this five-pointed star plate is mainly connected with gear changing arm component, its processing process is: boring → Che Kongyi deburring → heat treatment → car hole → sew with long stitches hole → end face milling → pincers → product inspection, it is in machining process, need to use drilling machine, numerically controlled lathe, honing machine and milling machine, at drilling machine, numerically controlled lathe, honing machine and milling machine need 3 secondary special fixtures altogether, owing to product needed repeatedly removes and installs, cause that the position error of product is bigger, make the qualification rate of product 70～75%, additionally in clamping milling process, we have found that existing milling fixture has following defects that
1, clamping times many, circulation time length, easily cause resetting error and knock damage；
2, ensureing that 3 kinds of (similar) product average productivities are at 390,000, always need equipment 9, always need number 11 people, workman's year total wages need 600,000 yuan.
Summary of the invention
In view of this, it is an object of the invention to provide a kind of five-pointed star plate milling fixture, this five-pointed star plate milling fixture is only with a set of, just can complete end face milling and bore hole on vertical knee-type milling machine, clamped one time location just can complete original Set and Positioning processing content repeatedly, reduce fixture cost, improve the quality of production efficiency and product.
In order to achieve the above object, one five-pointed star plate milling fixture of the present invention, including be arranged on workbench upper plate and be arranged on base plate no less than 3 pieces of chucks, described base plate are provided with for chuck slide guide rail, described card armor is set as the cavity holding five-pointed star plate, it is provided with the groove of the corner angle holding five-pointed star plate no less than 2 between described chuck, described chuck is provided with locking device.
Further, described guide rail is set to dovetail groove, and described chuck is provided with the slide block slided along dovetail groove.
Further, described chuck edge is set to hierarchic structure, and described five-pointed star is dialled and is supported on chuck edge.
Further, the angle between described adjacent trenches is set to 60o or 120o.
Further, described locking device includes the fastening bolt that is symmetricly set on chuck.
The beneficial effects of the present invention is:
1, after process modification, always needing equipment 1, always need number 3 people, workman's year total wages need 10.8 ten thousand yuan；
2, wage for workmen can save 160,000 yuan every year, within 3 years, saves 480,000 yuan and just can be reclaimed by equipment funds, and workman can remain 5 people.Can reducing product waste loss 50,000 yuan every year to be processed at one time by original Set and Positioning repeatedly due to disposable Set and Positioning, product quality can increase substantially..

Fig. 2 is the side view of five-pointed star plate；
Fig. 3 is the structural representation of five-pointed star plate milling fixture of the present invention.
Accompanying drawing labelling: 1-five-pointed star plate;2-corner angle;3-cavity;4-base plate；5-edge；6-guide rail；7-chuck；8-locking device；9-groove.
Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail.
It is illustrated in figure 3 the structural representation of five-pointed star plate milling fixture of the present invention；The present invention a kind of five-pointed star plate milling fixture include being arranged on workbench upper plate 4 and be arranged on base plate 4 no less than 3 pieces of chucks 7, described base plate 4 are provided with the guide rail 6 slided for chuck 7, described chuck 7 encloses and is set as the cavity 3 holding five-pointed star plate 1, it is provided with the groove 9 of the corner angle 2 holding five-pointed star plate 1 no less than 2 between described chuck 7, described chuck 7 is provided with locking device.
Five-pointed star plate 1 is fixed in cavity 3 by mobile chuck 7 by this enforcement, gap between chuck 7 is for fixing the corner angle 2 of five-pointed star plate 1, can quickly position, clamp workpiece, solid and reliable, only with a set of, it is possible to complete end face milling and bore hole on vertical knee-type milling machine, clamped one time location just can complete original Set and Positioning processing content repeatedly, reduce fixture cost, improve the quality of production efficiency and product.
Further, it is preferred that described guide rail 6 is set to dovetail groove, described chuck 7 being provided with the slide block slided along dovetail groove, this structure is easy to chuck 7 and is slided on guide rail 6.
Further, it is preferred that described chuck 7 edge is set to hierarchic structure, described five-pointed star plate 1 is supported on chuck 7 edge 5, and this structure is conducive to chuck 7 clamping five-pointed star plate 1, it is to avoid five-pointed star plate 1 loosens in the course of processing or slides.
Further, it is preferred that the angle between described adjacent trenches 9 is set to 60o or 120o, it is preferred that groove 9 is provided with rounding, it is simple to clamping workpiece.
Further, it is preferred that described locking device includes the fastening bolt 8 being symmetricly set on chuck, this structure is easy to fixing chuck 7.
What finally illustrate is, preferred embodiment above is only in order to illustrate technical scheme and unrestricted, although the present invention being described in detail by above preferred embodiment, but skilled artisan would appreciate that, in the form and details it can be made various change, without departing from claims of the present invention limited range.
