Problems solved by technology

However, with the development of the product series, in the process of processing high-precision large-diameter products, the coaxiality of the product does not meet the requirements, the service life of the chuck is reduced, and the clamping is not tight or loose. By analyzing the original structure, The reasons for the above phenomenon of the parts: (1) The size of the parts is enlarged; (2) The wear of the transmission part; (3) The problem of the structure itself

Embodiment Construction

[0013] With reference to the accompanying drawings: the power chuck is mainly composed of a chuck body 1, a slide seat 2, a T-shaped key 3, a claw 4, a dust cover 5, a sliding shaft 6, a positioning key 7, an adjustment pad 8, and a pull rod 9. The separated chuck body manufactures the chuck packing and the guide block separately, and then assembles them into one body, changing the guide groove from an overall semi-closed structure to an open surface, improving the groove width accuracy and the smoothness of the guide surface, and improving the quality of the chuck. The movement accuracy and service life of the disc are improved; the inverted cone chuck is also interchangeable; the rounded corner transition is used to increase the diameter range of the clamped workpiece.

[0014] Chuck body 1 is connected together with cylinder or oil cylinder piston by connecting screw and pull rod 9. When the cylinder is ventilated and the piston is moved, the connecting screw also moves wit...

Abstract

The invention discloses a split type inverted wedge type power chuck for a machine, which mainly comprises a chuck body, a sliding seat, a T-shaped key, a clamping jaw, a dustproof cover, a sliding shaft, a location key, a regulating pad and a pull rod, wherein an integral semi-closed structure of a guide groove is changed into an open surface, thus groove width precision and smooth finish of a guide surface are improved, and movement precision and service life of the chuck are improved; and by adopting an inverted cone chuck, the split type inverted wedge type power chuck has replaceability. By adopting round corner transition, the diameter range of clamping a workpiece is increased. A packing and a guide block of the chuck are separately manufactured, and then assembled into a whole, thus the split type inverted wedge type power chuck has the advantages of compact structure, convenience for maintenance, large clamping range, convenience for regulation, adjustable clamping force, higher automatic centering precision and the like.

Description

technical field [0001] The invention relates to a mechanical processing equipment, in particular to a machine-used split flip-chip wedge power chuck. Background technique [0002] The three-jaw self-centering chuck is a general-purpose fixture widely used in the mechanical manufacturing process to clamp workpieces. The traditional three-jaw automatic centering chuck uses a bevel gear pair and a plane thread pair to realize the cutting process of the force-clamping machine tool. Generally, the workpiece is clamped by three-jaw and four-jaw chucks, and its actions are also semi-manual. To achieve, it is not only time-consuming, but also very laborious. Especially when the production scale is large and the maneuvering time of the process is short, the contradiction is more prominent and becomes one of the main problems hindering the development of production. With the application and promotion of technologies using compressed gas and hydraulic oil as energy sources. Pneumati...
