Description
Technical field
The utility model relates to gear shaping automatic processing device, in particular to the dual spring collet fixture of one.
Background technology
Spring pinchcock hair style automatic fixture is widely used in tooth processed equipment lathe, for the processing of special elongate stepped shaft gear, utilizes traditional single spring pinchcock hair style automatic fixture to compare and is difficult to realize high precision, stable cutting, so this problem must solve.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of dual spring collet fixture, can meet the processing of elongate stepped shaft gear by this fixture, improves working (machining) efficiency while ensureing well processed precision and stability.
In order to solve the problem, the technical solution of the utility model is: a kind of dual spring collet fixture, comprises clamp body, locating sleeve it is provided with in clamp body, in locating sleeve, it is provided with spring chuck, one piece of dowel disc linked with spring pinchcock cover, in spring chuck, it is mounted with spring collet
Outside clamp body, it is provided with base, rotatably compresses oil cylinder, rotate clamping cylinder, pull bar and adapter sleeve, the two ends of pull bar are fixedly connected with one end of adapter sleeve with the pressure output end rotating clamping cylinder respectively, other one end of adapter sleeve is fixedly connected with dowel disc, rotatably compressing oil cylinder is installed on base, and the pressure output end rotatably compressing oil cylinder is positioned at the top of spring chuck.
Also comprise oil distribution mechanism, oil-releasing mechanism comprises joins oil block and sealing-ring, described in join oil block and be fixedly connected in the outside wall surface of clamp body, be mounted with sealing-ring between oil block and clamp body joining, being provided with oil supply hole on oil block joining, this oil supply hole is communicated in spring chuck through clamp body and locating sleeve.
Technique effect after employing the utility model is: utilize spring collet mechanism to realize the clamping of workpiece, ensure that clamping position, radial location is near cutting teeth portion, it is possible to effectively ensure cutting precision and stability.
Wherein, spring collet acts on spring chuck, it is achieved spring chuck and workpiece overall radial clamping and positioning; Rotate clamping cylinder and act on spring collet, realize the tension of spring collet by pull bar and adapter sleeve and unclamp; Rotatably compress oil cylinder mechanism and mainly realize elongate stepped shaft gear axial location; Oil distribution mechanism mainly utilizes that big oil amount is rushed to summit, turn up Integrated Chip, avoids iron filings residual spring collet inner and affects clamping stability.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described further:
Fig. 1 is diagrammatic cross-section of the present utility model,
Fig. 2 is the partial enlargement schematic diagram at A place in Fig. 1,
