Description
Technical field
The invention belongs to fuse and tighten automatic assembly technique field, be specifically related to a kind of body fuze and screw clamping device.
Background technology
Tighten in assembling at body fuze, existing tightening way is that the surperficial axial compression of the friction sleeve of rotation and fuse is produced moment of friction and realizes tightening of fuse by hold-down mechanism after the body clamping and positioning of will twist good fuse in advance.Thrust in this mode between friction sleeve and the fuse conical surface is produced by hold-down mechanism and the acting in conjunction of body clamp system, while friction sleeve and the fuse conical surface produce thrust, produce onesize thrust between fuse screw thread and body screw thread, the screw-down torque of fuse depends on moment of friction between friction sleeve and the fuse conical surface and the difference of moment of friction between fuse screw thread and body screw thread.Vital part in existing device for screwing up is friction sleeve, and in order to obtain larger frictional force and avoid friction sleeve that larger deformation occurs, friction sleeve have employed the silicon rubber that hardness is 60 degree.During actual production, owing to can produce skidding between friction sleeve and fuse, friction sleeve produces comparatively galling, tightens torsion and declines.
Summary of the invention
Can skidding be produced between the friction sleeve existed for prior art and fuse, produce comparatively galling, tighten torsion decline problem, the invention provides a kind of body fuze and screw clamping device.
Body fuze of the present invention screws clamping device, is characterized in: the sliding sleeve in described device is fixedly connected with clamping cone sleeve, and sliding sleeve is connected by slide key with main shaft, and can slide axially on main shaft; The piston of cylinder is fixedly connected with sliding sleeve, and the cylinder body of cylinder is fixedly connected with main shaft; Installation sleeve is fixedly connected with main shaft; Clamp is arranged in installation sleeve, and can radially slide; The outer cone of clamp is identical with the interior coning angle of clamping cone sleeve; Friction sleeve is arranged in clamp, and clamp radial direction is closed up and friction sleeve can be clamped; Locating cone A is contained in the hole of main shaft, and can slide axially; Stage clip is arranged between main shaft and locating cone A; Locating cone B is fixedly connected with installation sleeve.
Described friction sleeve adopt hardness be 35-40 silastic material make.
Body fuze of the present invention screw in clamping device slide over the promotion of described cylinder under slide on described main shaft, described clamp can radially slide in described installation sleeve, described locating cone A can axially be free to slide in described spindle hole, and described friction sleeve material have employed the silicon rubber that hardness is 35-40.Because cylinder promotes sliding sleeve, clamp radial direction is closed up by the clamping cone sleeve be fixed on sliding sleeve, the radial direction of clamp is closed up makes friction sleeve deform, thus make friction sleeve inner conical surface and fuse close contact, achieve the clamping of fuse, simultaneously because the positioning action of locating cone A and locating cone B makes the center of fuse and the alignment of shafts be consistent.
Device of the present invention can clamp reliably to taper fuse, realizes tightening of fuse by clamping torque, reduces the wearing and tearing of friction sleeve.
