Background technology
Current heat is around the spring of thicker wire diameter (steel wire diameter 40 ~ 100mm), due to steel wire slightly around time moment of torsion very big, so conduct is in steel wire process, the connection of the spring plug and lathe that are in center generally all adopts ring flange to be connected, and the manual operation amount of getting up to work that changes the outfit of ring flange is very large, bring very large trouble to the operation of changing plug.If adopt three-jaw clamping can not solve again the problem of high pulling torque.
Therefore, how the spring plug of quick-replaceable heat when thicker wire (high pulling torque) concerning operator being very stubborn problem.
Summary of the invention
The utility model for solve in known technology the how quick-replaceable heat that exists around thicker wire time spring plug and the technical problem of high pulling torque can be solved and a kind of spring plug self centering clamping device is provided.
The technical scheme that the utility model is taked for the technical problem existed in solution known technology is:
A kind of spring plug self centering clamping device, comprise fixed body, clamp and skewback, described clamp is positioned at fixed body and removable, the medial surface of described clamp is provided with " V " shape face, a lateral surface of described clamp and the medial surface wedge-like engagement of skewback, the end face of described skewback is provided with roll adjustment screw.
Described clamp comprises left clamp and right clamp, and described left clamp is connected by little spring with right clamp.
" V " shape face of described left clamp/right clamp is upper and lower is respectively provided with a vertical guide, and the vertical guide that described left clamp is relative with on right clamp is respectively provided with an installing hole, and described two installing hole bottom surfaces connect the two ends of little spring respectively.
The keyway with plug detent fit is provided with bottom " V " shape face of described clamp.
Described skewback is " U " shape block, and the medial surface of described skewback is the inclined-plane forming wedge-like engagement with clamp lateral surface, and the angle between this inclined-plane and bottom surface is obtuse angle.
Described fixed body is made up of discoid gripper shoe and tubular limited block.
Described roll adjustment screw is connected with the discoid gripper shoe of fixed body by gripper shoe.
Skewback lateral surface below described roll adjustment screw is connected with a compact heap, described roll adjustment screw is connected with skewback by compact heap.
The advantage that the utility model has and good effect are:
1. the utility model structure is simple, skewback roll adjustment screw effect under move up and down, the skewback with wedge-like engagement face is made to contact with clamp or depart from, thus make the clamp with " V " shape medial surface under the effect of spring external force, clamp plug or unclamp plug, reach the object of fast changeable plug, substantially increase operating efficiency, reduce the manipulation strength of workman.
2. keyway and plug detent fit, can play the effect increasing moment of torsion.
Accompanying drawing explanation
Fig. 1 is that the utility model master looks sectional structure schematic diagram;
Fig. 2 is the utility model diagrammatic side-view cross-sectional structural representation.
In Fig. 1 and Fig. 2: 1. skewback, 2. clamp, 201. left clamps, 202. right clamps, 3. adjust screw, 4. fixed body, 401. gripper shoes, 402. limited blocks, 5. plug, 6. keyway, 7. alignment pin, 8. little spring, 9. gripper shoe, 10. pressing plate.
Detailed description of the invention
For summary of the invention of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1 and Fig. 2, a kind of spring plug self centering clamping device, comprise the fixed body 4 connected with lathe rotary body, skewback 1 and can the clamp 2 of movement in fixed body 4, fixed body 4 is made up of discoid gripper shoe 401 and tubular limited block 402, clamp 2 is positioned at the limited block 402 of fixed body 4, clamp 2 medial surface is provided with " V " shape face with spring core rod touch, a lateral surface of clamp 2 and the medial surface wedge-like engagement of skewback 1, skewback 1 is " U " shape block, the medial surface of skewback 1 is the inclined-plane forming wedge-like engagement with clamp lateral surface, angle between this inclined-plane and bottom surface is obtuse angle, the end face of skewback 1 is provided with roll adjustment screw 3.
As a kind of preferred version, clamp comprises left clamp 201 and right clamp 202, left clamp 201 is connected by little spring 8 with right clamp 202, more preferred scheme is, on " V " shape face of left clamp/right clamp, under be respectively provided with a vertical guide, the vertical guide that left clamp is relative with on right clamp is respectively provided with an installing hole, two installing hole bottom surfaces connect the two ends of little spring respectively, left like this clamp 201 and right clamp 202 are by going up respectively, lower two horizontally disposed little springs 8 link together, can ensure that the spring plug being positioned at clamp is clamped under external force or unclamps, in turn simplify processing technology, make structure simpler, reduce cost.
Be provided with the keyway 6 coordinated with plug alignment pin 7 bottom " V " shape face of clamp 2, keyway 6 coordinates with alignment pin 7, can play the effect increasing moment of torsion.
Adjustment screw 3 is connected with fixed body by gripper shoe 9, can make more compact structure.
Skewback 1 lateral surface below roll adjustment screw 3 is connected with a compact heap 10, and roll adjustment screw 3 is connected with skewback 1 by compact heap 10.
The utility model in use, fixed body 4 is connected with lathe rotary body, when roll adjustment screw 3 is rotated down, skewback 1 roll adjustment screw 3 spinning force under skewback 1 is moved down, due to a lateral surface of clamp 2 and the medial surface wedge-like engagement of skewback 1, make skewback 1 drive left clamp 201 and right clamp 202 to move in opposite directions in fixed body 4, clamp 2 clamps plug 5 and locks; When roll adjustment screw 3 rotates up, skewback 1 moves up and unclamps clamp 2, and the relative movement under the effect of little spring 8 of left clamp 201 and right clamp 202, unclamps to both sides, loosen the clamping force to plug, and playing can the effect of quick change plug 5 soon.
