Description
Technical field
The present invention relates to a kind of clamping device.
Background technology
Clamping device is applicable to generally in various types of machineds that general left and right sides chuck is arranged on the base by leading screw respectively.When changing material, need the hand rotation leading screw that left and right sides chuck is outwards separated; After having changed, the hand rotation leading screw inwardly clamps left and right sides chuck again, during owing to operating cost, has reduced production efficiency.
Summary of the invention
Technical problem to be solved by this invention is: a kind of clamping device of being convenient to reload fast is provided.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of clamping device, comprise base, be movably arranged on left fixture block and right fixture block on the base, described base is provided with projection, rotate in the projection and be equipped with installation shaft, on the installation shaft in the both sides of projection respectively movable sleeve be provided with mounting blocks, described left fixture block is connected with the mounting blocks of respective side respectively with right fixture block, on the installation shaft both sides respectively movable sleeve be provided with the Connection Block of the hollow that links to each other with mounting blocks, be arranged with the end cap that links to each other with Connection Block on the installation shaft, be provided with the driving oil cylinder in the end cap outside on the installation shaft, end cap is connected with the force-output shaft that drives oil cylinder, both sides are connected with drive block respectively by the opposite screw thread of rotation direction on the installation shaft, drive block is arranged in the cavity of Connection Block and end cap formation, and Connection Block and end cap can axially produce the displacement of certain distance along installation shaft with respect to drive block.
Described drive block comprises the tubular external part that body and body both sides axially arrange along installation shaft, and two external parts of drive block are embedded respectively in Connection Block and end cap.
Described installation shaft one end is provided with the rotation handwheel.
The invention has the beneficial effects as follows: this clamping device can thoroughly separate left and right fixture block by rotating installation shaft as required, can unclamp the operation of reloading fast by the left and right fixture block of hydraulic oil cylinder driving again, the operation rapid and convenient.
Description of drawings
Fig. 1 is structural representation of the present invention.
Among Fig. 1: 1. base, 11. projections, 2. left fixture block, 3. right fixture block, 4. installation shaft is 5. rotated handwheel, 6. mounting blocks, 7. Connection Block, 8. end cap 9. drives oil cylinder, 10. drive block.
The specific embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the present invention in detail.
As shown in Figure 1, a kind of clamping device comprises base 1, is movably arranged on left fixture block 2 and right fixture block 3 on the base 1, and described base 1 is provided with projection 11, rotates in the projection 11 and is equipped with installation shaft 4, and installation shaft 4 one side ends are provided with and rotate handwheel 5.On the installation shaft 4 in the both sides of projection 11 respectively movable sleeve be provided with mounting blocks 6, described left fixture block 2 is connected with the mounting blocks 6 of respective side respectively with right fixture block 3, on the installation shaft 4 both sides respectively movable sleeve be provided with the Connection Block 7 of the hollow that links to each other with mounting blocks 6, be arranged with the end cap 8 that links to each other with Connection Block 7 on the installation shaft 4, be provided with in end cap 8 outsides on the installation shaft 4 and drive oil cylinder 9, end cap 8 is connected with the force-output shaft that drives oil cylinder 9, both sides are connected with drive block 10 respectively by the opposite screw thread of rotation direction on the installation shaft 4, drive block 10 is arranged in the cavity of Connection Block 7 and end cap 8 formation, described drive block 10 comprises the tubular external part that body and body both sides axially arrange along installation shaft 4, and two external parts of drive block 10 are embedded respectively in Connection Block 7 and end cap 8.Connection Block 7 and end cap 8 can be along the installation shaft 4 axial displacements that produce certain distances with respect to drive block 10.
Owing to be provided with in end cap 8 outsides on the installation shaft 4 and drive oil cylinder 9, end cap 8 is connected with the force-output shaft that drives oil cylinder 9, both sides are connected with drive block 10 respectively by the opposite screw thread of rotation direction on the installation shaft 4, drive block 10 is arranged in the cavity of Connection Block 7 and end cap 8 formation, Connection Block 7 and end cap 8 can be along the installation shaft 4 axial displacements that produce certain distances with respect to drive block 10, when machining gap need reload, can Connection Block 7 outwards be drawn back a segment distance by driving oil cylinder 9, make left fixture block 2 and right fixture block 3 unclamp, the operation of can reloading; If desired left fixture block 2 and right fixture block 3 are separated fully, then turn installation shaft 4, both sides drive block 10 moves round about, promotes end cap 8 and Connection Block 7 and outwards moves, thereby left fixture block 2 and right fixture block 3 are separated fully.
The above embodiments are principle and the effect thereof of illustrative the invention only, and the embodiment of part utilization, but not is used for restriction the present invention; Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the invention design, can also make some distortion and improvement, these all belong to protection scope of the present invention.
