Abstract
The utility model belongs to a clamp for drilling of root valve body lower inclined holes. The clamp comprises a clamp body (1), and is characterized in that an included angle alpha is formed between a clamp body top board (1-2) and a clamp body bottom board (1-1), a front baffle (2) is fixed to the right end of the clamp body top board (1-2) through an M8*20 screw (3), a rear side baffle (4) and a front side baffle (8) are fixed to the front baffle (2) through M8*20 screws (3), a lead screw (7) is in threaded connection with the front side baffle (8), a hand wheel (9) is fixed to the right end of the lead screw (7) through an M8 nut (11) and a gasket (10) with the diameter of 8 mm, and a clamping block (5) is installed at the left end of the lead screw (7) through a pin (6). The included angle alpha formed between the clamp body top board (1-2) and the clamp body bottom board (1-1) ranges from 30 degrees to 40 degrees. The clamp ensures the machining quality of the root valve body lower inclined holes, no waste product exists, material cost and machining cost are saved, installation is convenient and rapid, and production efficiency is improved.
Description
Technical field
The utility model belongs to machining facility, particularly inclined hole fixture under a kind of brill root valve valve body.
Background technology
Bore inclined hole under root valve valve body, on drilling machine, process, requirement is ensured the quality of products, how fixing very difficult on workbench, there is no suitable special fixture, in process, percent defective will increase, waste material and man-hour, particularly this valve body has passed through multiple processing handling procedure, scraps waste greatly at boring procedure.
Summary of the invention
The object of the invention is to overcome above-mentioned technical deficiency, a kind of special fixture is provided, improve yield rate, inclined hole fixture under the brill root valve valve body of assurance crudy.
The technical scheme that the utility model technical solution problem adopts is: inclined hole fixture under a kind of brill root valve valve body, comprise clamp body, and the angle that it is characterized in that clamp body top board and clamp bottom board is α; M8 × 20 screw for right-hand member at fixture top board is fixed with front apron, on front apron, is fixed with rear side shield and front side shield with M8 × 20 screw; The leading screw that is threaded on front side shield, the right-hand member of leading screw is fixed a handwheel with M8 nut and φ 8 packing rings, and the left end of leading screw fills the fixture block of a copper with pin.Angle α=30～40 between clamp body top board and clamp body base plate
0.
The beneficial effects of the utility model are: this utility model has been guaranteed the crudy of inclined hole under root valve valve body, does not go out waste product, has saved material and processing charges; Quick and easy for installation, enhance productivity.
Accompanying drawing explanation
below in conjunction with accompanying drawing, illustrate with embodiment.
Fig. 1 is the front view that bores inclined hole fixture under root valve valve body;
Fig. 2 is that the K of Fig. 1 is to diagram;
Fig. 3 is the C-C profile of Fig. 1.
In figure: 1-clamp body; 1-1-clamp body base plate; 1-2-clamp body top board; 2-front apron; 3-M8 × 20 screw; 4-rear side shield; 5-fixture block; 6-pin; 7-leading screw; 8-front side plate washer; 9-handwheel; 10-φ, 8 packing rings; 11-M8 nut; 12-root valve valve body; Inclined hole under 13-root valve; 14-hole; The angle of α-clamp body top board and clamp body base plate.
The specific embodiment
Embodiment, with reference to accompanying drawing, a kind of bores inclined hole fixture under root valve valve body, comprises clamp body 1, it is characterized in that the angle between body plate 1-1 is α at the bottom of clamp body top board 1-2 and fixture; M8 × 20 screw 3 for right-hand member at fixture top board 1-2 is fixed with front apron 2, on front apron 2, is fixed with rear side shield 4 and front side shield 8 with M8 × 20 screw 3; The leading screw 7 that is threaded on front side shield 8, the right-hand member of leading screw 7 is fixed a handwheel 9 with M8 nut 11 and φ 8 packing rings 10, and the left end of leading screw 7 fills the fixture block 5 of a copper with pin 6.Angle α=30～40 between clamp body top board 1-2 and clamp body base plate 1-1
0.Clamp body 1 is to adopt Q235-A material to be welded; Fixture top board 1-2 is provided with hole 14, valve body convenient for assembly.
Operating process is: root valve body 12 is placed on after clamp body top board 1-2 between side shield 4 and fixture block 5, puts and rotate just afterwards handwheel 10 and drive leading screw 7 and fixture block 5 that root valve body 12 is clamped, available drilling machine bores root valve body declivity hole 13.Easy to assembly quick, be very beneficial for the processing of inclined hole.
