Utility model content
The purpose of this utility model is to solve need to repeatedly unscrew at present with tighten the screws and could realizes the problem of boring discharge pine and locking and could realize brill and arrange rotation, and a kind of box Pneumatic locking device that can automatic rotation is provided.
For achieving the above object, the technical scheme that the utility model provides is as follows:
The box Pneumatic locking device that the utility model provides comprises successively by brill row, gas lock clutch and the motor arranged from top to bottom, on motor, be provided with transposition axle, described gas lock clutch comprises successively by gas lock box seat, gas lock gland, the gentle lock of gas lock piston arranged from top to bottom;
Described gas lock gland center is provided with the cavity that runs through gas lock gland, is provided with locating hole in the edge of gas lock gland, is also provided with inlet channel in the side of gas lock gland; From the edge of described gas lock piston to its central authorities, set gradually groove, boss and run through the circular hole of gas lock piston; Described gas lock seat center is provided with the spacing hole suitable with the base of gas lock piston;
The boss of gas lock piston and base are positioned over respectively in cavity and spacing hole, and the transposition axle on motor inserts in the circular hole of gas lock piston; In the locating hole of gas lock gland, be inserted with a locating dowel; Between gas lock gland and gas lock piston, cover has the first sealing ring and the second sealing ring, has formed an annular seal space between gas lock gland and gas lock piston.
Especially, the longitudinal section of the cavity on described gas lock gland is convex shape.
Especially, described groove is stepped.
Especially, the spacing hole of described gas lock seat is with tapering.
The beneficial effects of the utility model: the formation of gas lock clutch is simple, main member only includes these four of gas lock box seats, gas lock gland, the gentle lock of gas lock piston, and these four members is simple in structure, less demanding to processing and forming technology; Only each member need be superimposed together in order, be loaded on the securing members such as screw, this box Pneumatic locking device can be fitted together, installation and removal are all easy to; By adjusting the air pressure in annular seal space, can lock gas lock piston, also can make the release of gas lock piston, thereby can rotate the row of boring.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further, the present embodiment only represents a kind of preferred forms, should not form restriction of the present utility model.
As shown in Figure 1 to Figure 3, the box Pneumatic locking device that the utility model provides comprises the row of boring 1, gas lock clutch and motor 2, is provided with transposition axle 21 on motor 2, and gas lock clutch comprises gas lock box seat 3, gas lock gland 4, the gentle lock 6 of gas lock piston 5; On gas lock gland 4, be provided with a cavity 41 that runs through gas lock gland 4, the longitudinal section of this cavity 41 is convex shape, is also provided with a locating hole 42 in the edge of gas lock gland 4, is also provided with inlet channel 43 in the side of gas lock gland 4; From the edge of gas lock piston 5 to its central authorities, set gradually groove 53, boss 51 and run through the circular hole 52 of gas lock piston 5; Gas lock seat 6 centers are provided with the spacing hole 61 suitable with the base of gas lock piston 5, and the spacing hole 61 of gas lock seat 6 is with tapering.
The installation process of the box Pneumatic locking device that the utility model provides is as follows: the row of boring 1, gas lock box seat 3, gas lock gland 4, gas lock seat 6 and motor 2 are arranged according to order from top to bottom, the base of gas lock piston 5 and boss 51 are placed on respectively in cavity 41 and spacing hole 61, transposition axle 21 on motor 2 inserts in the circular hole 52 of gas lock piston 5, gas lock box seat 3 is fixed together with the row of boring 1 and gas lock piston 5 respectively, gas lock seat 6 is fixed together with gas lock gland 4 and motor 2 respectively, is inserted with a locating dowel 7 in the locating hole 42 of gas lock gland 4; Between gas lock gland 4 and gas lock piston 5, cover has the first sealing ring 8 and the second sealing ring 9, has formed an annular seal space 10 between gas lock gland 4 and gas lock piston 5.
The course of work of the box Pneumatic locking device that the utility model provides is as follows: control the air pressure in annular seal space 10 by inlet channel 43, after the interior air inlet of annular seal space 10, the first sealing ring 8 and the second sealing ring 9 stop air to leak outside, gas lock gland 4 can be subject to a power upwards, gas lock piston 5 can be subject to a downward power, due to gas lock piston 5 and spacing hole 61 and between form taper fit, gas lock piston 5 pushes mutually with gas lock seat 6, utilize the principle of frictional force, can transmit certain moment of torsion, in the time that air pressure is enough high, can stop gas lock piston 5 to rotate with motor 2, in the time that needs rotate, by inlet channel 43 releases, the frictional force between gas lock piston 5 and gas lock seat 6 reduces, and gas lock piston 5 can rotate, and drives gas lock box seat 3 and the row of boring 1 to rotate.
