Preferably, the chip escaping groove is arranged on the clamping tool positioning plate. The structure of the special clamping tool can be used for avoiding producing vacuum effect between the machining positioning surface and the clamping tool positioning plate; therefore, the working efficiency is improved. The special clamping tool is mainly used for machining parts of electric tools made of magnesium alloy and ensuring the stable machining process of products.
Description
Technical field
The utility model relates to a kind of instrument that is used for machining, specifically, relates to a kind of machining special fixture.
Background technology
Under the method for clamping of existing anchor clamps, cutter and pressure head can interfere, can not be disposable when processing ф 83.00 external diameters walk full circle processing, finish processing and must walk 4 sections circular arcs, the very unstable circularity of the diameter of the product ф 83.00 that this kind processing mode processes is also very bad.Also owing to will divide four sections processing herein, write so the machining program also will be divided four sections simultaneously, so also inconvenient field technician writes formula and debugging operation.And the structure of existing anchor clamps, because of the mechanical processing and positioning datum level of product be whole as the mechanical processing and positioning face, the F datum level can be after station two machines after machining, and mechanical processing and positioning face and jig plate face produce vacuum effect and cause the operator to be difficult to pick and place the problem of product in process of production.
The machining accuracy aspect, existing clamp for machining can only be controlled at ± 0.04mm the external diameter machining accuracy of product, and circularity also can only be controlled in the 0.04mm, does not more and more satisfy the demand of the processing operation that required precision increases day by day.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of machining special fixture, can solve the destabilizing factor in the production, to shorten cycle time for working, increases work efficiency.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of machining special fixture, comprise anchor clamps location-plate, the first location datum mark, the second location datum mark, the 3rd location datum mark, first fixed locating stud, first elastic positioning pin, second fixed locating stud, second elastic positioning pin, mechanical processing and positioning face, first pressure head, second pressure head and scrap removing groove, wherein, the described first location datum mark, the described second location datum mark, described the 3rd location datum mark, described first fixed locating stud and described first elastic positioning pin are on station one; Described second fixed locating stud, described second elastic positioning pin, described mechanical processing and positioning face, described first pressure head, described second pressure head and described scrap removing groove are on station two, it is characterized in that: the described first location datum mark, described second location datum mark and described the 3rd location datum mark are isosceles triangle and arrange at grade; Described scrap removing groove is arranged on the described anchor clamps location-plate.
Further, described first pressure head is arranged on the described second fixed locating stud upper right side, and described second pressure head is arranged on and described first pressure head position diagonally.
Further, described scrap removing groove is arranged on the part of station two of described anchor clamps location-plate.
Further, described scrap removing groove is a hollow out at described anchor clamps location-plate, and four symmetrical horizontal distribution of a row are on the part of the station two of described anchor clamps location-plate.
Be compared with the prior art, adopt the advantage of the technical solution of the utility model to be:
1. change the pressure holding position of anchor clamps pressure head, avoid the action route of process tool, improve the stability of processing.In structure of the present utility model, the pressure holding position of first pressure head and second pressure head, avoid the action route of process tool, make cutter can once finish processing, divide four sections cooked modes that machine thereby replace existing anchor clamps to this four boss outside diameter ф 83.00.Like this, in each fabrication cycles, can save the process time of 6S, and whole processing is all very stable.
2. scrap removing groove is set, avoids mechanical processing and positioning face and jig plate face to produce vacuum effect, increase work efficiency.In the novel structure of this use, be provided with scrap removing groove at the second station place of anchor clamps location-plate, can avoid mechanical processing and positioning face and jig plate face to produce vacuum effect, thereby convenient working person's production operation is increased work efficiency.
