Description

A kind of fast-clamping clamp
Technical field
The invention belongs to frock clamp field, specifically, particularly relate to a kind of fast-clamping clamp for clamping gear, sleeve workpiece etc.
Background technology
At present, for the clamping of the workpiece such as gear, sleeve workpiece, general employing mandrel and Internal hole positioning, then the mode of increased pressure board and nut compression, and between mandrel and endoporus, there is gap.
The existing defect for fixtures such as clamping gear, sleeve workpieces is as follows:
1, owing to there is gap between the endoporus of workpiece and mandrel, work pieces process axiality out so just must be caused to be difficult to be guaranteed, thus to affect machining accuracy and the quality of product;
2, owing to adopting pressing plate and nut to compress, so quick-clamping poor-performing of fixture, is badly in need of solving above-mentioned technical barrier for this reason.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of fast-clamping clamp, for eliminating the gap between inner hole of workpiece and mandrel.
Technical scheme of the present invention is as follows: a kind of fast-clamping clamp, comprise mandrel (1), pressing plate (2) and nut (3), it is characterized in that: described mandrel (1) is five-part form multidiameter structure, be followed successively by first, second, third and fourth and five shaft parts from left to right, wherein the diameter of the first shaft part is less than the diameter of the second shaft part, second and third, the diameter of four and five shaft parts reduces successively, and the 3rd shaft part of mandrel (1) is set with a copper base ball retainer (4); Described pressing plate (2) is sleeved on the 4th shaft part of mandrel (1), the right part of this pressing plate periphery is provided with projection (2a), and be set with a cover plate (5) at the left part of pressing plate (2) periphery, the hole wall of cover central hole has groove (5a), and the number of this groove, position and size and described projection (2a) adapt;
The centre bore of described cover plate (5) is built with a stage clip (6), this stage clip is simultaneously on the 4th shaft part of described mandrel (1), and stage clip (6) left end abuts with the step surface of mandrel (1), and fit in the left plate face of stage clip (6) right-hand member and described pressing plate (2); Described nut (3) is sleeved on the 5th shaft part of mandrel (1), is threaded connection between both.
When adopting this fixture to come clamping workpiece (G), first load onto spring (6), pressing plate (2) and nut (3) and load onto axle, again workpiece (G) is sleeved on described copper base ball retainer (4) outside, and the steel ball close contact of the hole wall of workpiece (G) centre bore and copper base ball retainer (4), and the steel ball of copper base ball retainer (4) simultaneously with the axle body close contact of described mandrel (1).Finally load onto groove (5a) on cover plate (5) cover plate (5) to stagger with the projection (2a) on pressing plate (2), fastening nut (3), so just by workpiece (G) location, clamping; After completing processing, first nut (3) is twisted and send, again described cover plate (5) is turned an angle, groove (5a) on cover plate (5) is overlapped with projection (2a) position on pressing plate (2), so just cover plate (5) can be taken off, thus taken off by workpiece (G) quickly and easily, and then realize quick change.
Adopt above technical scheme, the present invention can realize the gap between the hole wall of workpiece (G) centre bore and mandrel (1) effectively by copper base ball retainer (4), so just can ensure the axiality requirement of workpiece (G) well, and then ensure machining accuracy and the quality of product, and this fixture just can realize quick change by tightening nut (3) and dismounting cover plate (5), thus overcome the defect of traditional structure well, and the structure of this fixture is simple, easy to implement, there is good practicality.
As preferably, the number of described projection (2a) is three, and these three projections (2a) are evenly arranged along the circumference of described pressing plate (2).
Certainly, in concrete manufacture process, the concrete number of projection (2a) can be selected according to actual needs, and the concrete number of protruding (2a) is not limited to the number described in the present embodiment.
As optimal design, the right panel face of described cover plate (5) is installed with an alignment pin (7), the axis parallel of the axial line of this alignment pin and cover plate (5).
Adopt above structure, described alignment pin (7) contacts with the projection (2a) of pressing plate (2), thus carries out circumference location to cover plate (5).
As preferably, the first shaft part and the 4th shaft part of described mandrel (1) are flat part, and the centre bore of described pressing plate (2) is flat hole.
Adopt above structure, first shaft part of described mandrel (1) adopts flat part, and object is for the ease of clamping, and the 4th shaft part of mandrel (1) adopts flat part, and the centre bore of described pressing plate (2) correspondence adopts flat hole, is to prevent pressing plate (2) from rotating like this.
Beneficial effect: the present invention can realize the gap between the hole wall of workpiece (G) centre bore and mandrel (1) effectively by copper base ball retainer (4), so just can ensure the axiality requirement of workpiece (G) well, and then ensure machining accuracy and the quality of product, and this fixture just can realize quick change by tightening nut (3) and dismounting cover plate (5), thus overcome the defect of traditional structure well, and the structure of this fixture is simple, easy to implement, there is good practicality.
