Description
Technical field
The utility model relates to lever automatic compacting device, this device install with lathe with the use of, belong to frock clamp field.
Background technology
Bent axle usually first carries out turnery processing to bent axle major axis outer surface in process, again to its fine grinding, no matter turning or refine and all will be fixed on machine chuck, the clamping of common chuck clamps adopts two two taper surfaces, and oppositely movement is to clamp workpiece, and such structure manufacture is simple, but is static friction between face and face, lubrication not wearing and tearing is very fast, therefore it is impermanent to use, and uses later stage gap comparatively large, affects machining accuracy.
Utility model content
The purpose of this utility model is to overcome above shortcomings in prior art, and provides a kind of reasonable in design, reliable and stable, the lever automatic compacting device that adopts rolling friction and leverage principle design.
The technical scheme in the invention for solving the above technical problem is: this lever automatic compacting device, comprise installing plate, housing, lever, bearing, tension block, pressing plate, V-block, be hollow cavity in housing, hollow cavity is provided with gathering sill, lever, bearing, tension block, pressing plate, V-block is all located in this hollow cavity, tension block and hollow cavity are closely slidably installed, installing plate fixedly mounts near tension block and housing, tension block is integrated mechanism, tension block is provided with sliver and tension inclined-plane, sliver coordinates with gathering sill to be installed, sliver with tension inclined-plane be positioned at strain block diagonal on, inclined-plane is structure low inside the height of outside, lever and housing into rotation are installed, lever two ends respectively with bearing, press plate rotary connects, bearing is located in tension block, bearing outer ring is conflicted and is strained inclined-plane, corresponding V-block below pressing plate, V-block is fixedly connected with housing.
Furtherly, described tension block also comprises gag lever post, and gag lever post is located at the both sides of sliver, leaves space between two gag lever posts.
Furtherly, pressing plate is provided with V-type groove.
The utility model compared with prior art, has the following advantages and effect:
1, hold-down mechanism of the present utility model adopts lever principle, apply less power, larger power can be produced, the power applied due to the external world limits by lathe usually, with the maximum output that can only realize 1:1 of normal compression mode, and the utility model can amplify according to lever principle, therefore compress effective.
2, bearing described in the utility model and tension block are rolling friction, and frictional resistance is little, and under frictional dissipation, it is more permanent to use.
3, tension block described in the utility model is provided with gag lever post, and axle bed is located in the gap between two gag lever posts, and gag lever post can Limit Bearing, runs more stable smooth.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is for straining the structural representation of block described in the utility model embodiment.
Fig. 3 is the structural representation of pressing plate described in the utility model embodiment.
Detailed description of the invention
Below in conjunction with accompanying drawing, also by embodiment, the utility model is described in further detail, and following examples are that the utility model is not limited to following examples to explanation of the present utility model.
See Fig. 1 to Fig. 3, lever automatic compacting device described in the utility model, comprise installing plate 1, housing 2, lever 3, bearing 4, tension block 5, pressing plate 6 and V-block 7, installing plate 1 and pressing plate 6 are positioned at the two ends of housing 2, be hollow cavity in housing 2, hollow cavity is provided with gathering sill 21, lever 3, bearing 4, tension block 5, pressing plate 6, V-block 7 is all located in this hollow cavity, tension block 5 is closely slidably installed with hollow cavity, tension block 5 is integrated mechanism, tension block 5 is provided with sliver 51 and tension inclined-plane 52, sliver 51 coordinates with gathering sill 21 to be installed, installing plate 1 fixedly mounts with housing 2 near tension block 5, it is spacing in middle control cavity that installing plate 1 will strain block 5, the opposite of sliver 51 is tension inclined-plane 52, sliver 51 and tension inclined-plane 52 be positioned at strain block 5 diagonal on, inclined-plane is structure low inside the height of outside, described tension block 5 also comprises gag lever post 53, gag lever post 53 is located at the both sides of sliver 51, space is left between two gag lever posts 53, bearing 4 is located in tension block 5, conflict and strain inclined-plane 52 in bearing 4 outer ring, described lever 3 adopts lever pin 8 to rotate with housing 2 and installs, lever 3 two ends respectively with bearing 4, pressing plate 6 is rotationally connected, corresponding V-block 7 below pressing plate 6, V-block 7 is fixedly connected with housing 2.Furtherly, furtherly, pressing plate 6 is provided with V-type groove 61.
The course of work, installing plate 1 is fixedly connected with lathe, cylinder on lathe connects tension block 5, when hold down gag described in the utility model is in relaxed state, bearing 4 is positioned at the low ebb on stretching inclined-plane 52, open configuration is in because lever principle pressing plate 6 moves, cylinder action pulls tension block 5 that bearing 4 is moved towards the eminence on stretching inclined-plane 52, and affect pressing plate 6 by this and move down, hold down gag described in the utility model becomes clamped condition.
