Description
Technical field
The invention belongs to machine tool fixture fields, and in particular to a kind of symmetrical clamping device.
Background technique
In the positioning of machining, when involving the need for symmetrically clamping part, the machine that can be moved synchronously in opposite directions is provided
Structure, and can be self-locking.It is high to the required precision of screw thread using the vice type clamping device of double threaded screw transmission, cause manufacture at
This height.
Summary of the invention
The technical problems to be solved by the present invention are: symmetrical clamping device provided by the invention, structure is complicated with lower
Degree solves the problems, such as that prior art manufacturing cost is high.
The symmetrical clamping device of the present invention, the device are equipped with the left sliding panel and right sliding panel to horizontally slip on pedestal,
Left position housing piece and right position housing piece, the left sliding are separately installed in the left sliding panel and right sliding panel upper surface
Plate has right oblique angle in right part, and right sliding panel has left oblique angle in left part；It is sliding that the device is also equipped with front and back on pedestal
Dynamic jacking block, the front end of the jacking block are matched with the right oblique angle and left oblique angle type face, are clamped part by controlling the jacking block.
The pedestal has cavity in rear end face, is fixed with block in cavity outer end, jacking block has in the end face towards cavity
There is counterbore, there is thread segment in open area；After the end of housing screw rotates through the threaded hole of block, continues rotation and wear
The thread segment of jacking block is crossed, and is finally pressed against counterbore base.
The pedestal has longitudinal chute in upper surface, and jacking block is slidably mounted in the longitudinal chute.
The pedestal has horizontal concrete chute in upper surface, wherein being placed with the left sliding panel and right sliding panel, the two exist
Be staggered mutual insertion above and below interference region.
There is spring eye in the opposite end face of the left sliding panel and right sliding panel, wherein being placed with one or more bullets
Spring.
The jacking block has oblique angle in the part contacted with the right oblique angle and left oblique angle.
Housing screw has nut in the bar portion for passing through block, for locking housing screw.
By screwing housing screw, move forward and backward jacking block.
When jacking block travels forward, left sliding panel can be oppressed and right sliding panel moves toward one another, so that left positioning be driven to press
Tight block and right position housing piece Clamp blocks.
When jacking block moves backward, the left sliding panel and right sliding panel separate automatically under the action of the spring.
The utility model has the advantages that mechanism manufacture difficulty is lower, escapable cost realizes symmetrical clamping function.

Specific embodiment
Referring to Fig. 1, pedestal 9 has cavity in rear end face, block 12 is fixed with outside cavity.The pedestal 9 is in upper end mask
There is longitudinal chute, jacking block 2 is slidably mounted in the longitudinal chute.The jacking block 2 has counterbore in the end face towards cavity, is opening
Mouth region domain has thread segment.After the end of housing screw 1 rotates through block 12, continue the thread segment for rotating through jacking block 2, and
Finally it is pressed against counterbore base.Jacking block 2 can be made to move forward and backward by screwing housing screw 1.
Jacking block 2 has symmetrical oblique angle in the other end.Also there is horizontal concrete chute in the upper surface of pedestal 9, wherein sliding peace
Equipped with left sliding panel 3 and right sliding panel 4, the two is staggered mutual insertion in left-right direction, above and below interference region, and opposite
It is placed with spring 8 in the spring eye of end face, the left sliding panel 3 has a right oblique angle 10 in right part, and right sliding panel 4 is in left part
With left oblique angle 11.Right oblique angle 10 and left oblique angle 11 chamfered fit with the jacking block 2 respectively, are fixed in left 3 upper end of sliding panel
There is left position housing piece 6, is fixed with right position housing piece 5 in right 4 upper end of sliding panel.When jacking block 2 travels forward, can oppress
Left sliding panel 3 and right sliding panel 4 move toward one another, to drive 5 Clamp blocks of left position housing piece 6 and right position housing piece.When
When jacking block 2 moves backward, the left sliding panel 3 and right sliding panel 4 separate automatically under the action of spring 8.
Housing screw 1 has nut 7 in the bar portion for passing through block 12, can lock housing screw 1.
When operation, part is placed between right position housing piece 5 and left position housing piece 6, is pushed away by turn housing screw 1
Dynamic jacking block 2 travels forward, and right oblique angle 10 and left oblique angle 11 of the oblique angle of 2 front end of jacking block with left sliding panel 3 and on right sliding panel 4 are oblique
Degree matching, pushes left sliding panel 3 and right sliding panel 4 to move toward one another, so that left position housing piece 6 and right position housing piece 5
Part is clamped, tightening nut 7 come prevent housing screw 1 loosen.
Loosening nut 7, turn compressing pull rod 1 move backward, and jacking block 2 is driven to move backward, and spring 8 is by left 3 He of sliding panel
Right sliding panel 4 separates, and left position housing piece 6 and right position housing piece 5 is driven to unclamp part.
