Abstract
The invention discloses a chuck. The chuck comprises a chuck body and clamping claws. The clamping claws comprise a positioning clamping claw and a movable clamping claw. The positioning clamping claw and the movable clamping claw are respectively composed of a clamping claw connecting base and a clamping claw grasping part, wherein the clamping claw grasping part is provided with a swallow-tailed groove, a clamping-mark-preventing cushion block is arranged in the swallow-tailed groove, one end face of the clamping-mark-preventing cushion block is matched with the clamping claw grasping part, and the other end face of the clamping-mark-preventing cushion block is matched with a grasped face of a machined part. The positioning clamping claw and an adjusting bolt are fixed through a compression bolt, the bottom of the movable clamping claw is provided a positioning key, the chuck body is provided with a movable groove matched with the movable clamping claw, and the chuck body is provided with two ejector rods which can eject the machined part. The chuck is simple in structure, convenient to use, capable of effectively preventing the machined part from loosening and wide in application range, and the clamping marks are prevented form being formed on the machined part.
Description
Technical field
The present invention relates to the accessory field that machining is used, relate in particular to a kind of chuck.
Background technology
Chuck is on lathe, to be used for the mechanical device of clamping work pieces, utilizes and is distributed in the claw on chuck body, by Workpiece clamping and location.But there are a lot of problems in current chuck, such as can not clamp well very soon workpiece in operating process, workpiece clamp is not firm, there is the sliding phenomenon of pine in workpiece, in addition, and for axial workpiece or exist the part of curved surface to add man-hour, because the clamping part of the claw of existing chuck is planar structure, make so above-mentioned part after machining, clamping part is prone to catcher mark, thereby affects the precision of part.
Summary of the invention
The object of this invention is to provide a kind of chuck that can clamp well very soon part, effectively prevent part pine cunning, meanwhile, solved for axial workpiece or existed curved surface part to add man-hour, be prone to catcher mark, thereby affect the problem of element precision.
The technical solution used in the present invention is as follows:
A kind of chuck, comprise chuck body and claw, described claw comprises location claw and movable jaw, described location claw and movable jaw are all comprised of claw Connection Block and claw clamping part, described claw clamping part is provided with swallow-tailed groove, swallow-tailed groove is provided with clamp mark-proof cushion block, clamp mark-proof cushion block one end face and claw clamping part are suitable, other end and part to be processed to be held face suitable, described location claw interfixes by hold-down bolt and adjustment bolt, described movable jaw bottom is provided with positioning key, described chuck body is provided with the loose slot suitable with movable jaw, described chuck body is provided with two push rods that can hold out against part to be processed.
The suitable end face of described clamp mark-proof cushion block and the face that is held of part to be processed is circular-arc structure.
Described clamp mark-proof cushion block and claw clamping part are threaded connection, and are convenient to dismounting.
The angle that described swallow-tailed groove forms is 150 degree.
Described positioning key comprises longitudinal register key and located lateral key.
The central authorities of described chuck body are provided with manhole.
Described push rod is threaded connection and is arranged on chuck body, and push rod adopts the mode being threaded to be arranged on chuck body, is convenient to installation and the dismounting of push rod.
Compared with the prior art, beneficial effect of the present invention is as follows:
The present invention is by Design Orientation claw and movable jaw, location claw interfixes by hold-down bolt and adjustment bolt, movable jaw bottom is provided with positioning key, chuck body is provided with the loose slot suitable with movable jaw, during use, can conveniently clamp part, at claw clamping part, be provided with swallow-tailed groove, swallow-tailed groove is provided with clamp mark-proof cushion block, processing for all kinds of axial workpieces, can not produce catcher mark, guaranteed the precision of part to be processed, simultaneously, on chuck body, be provided with the push rod that can hold out against part to be processed, can effectively prevent that processing parts from occurring loosening, the sliding phenomenon of pine, increase the stability of part to be processed, improve the qualification rate of processing.The present invention is simple in structure, easy to use, applied widely.
