Abstract
The invention relates to a swing rod axial buckling chuck. The chuck comprises a power chuck body, wherein three chutes are uniformly distributed on the upper end face of the power chuck body along the radial direction; and bottom claws in sliding fit with the chutes are embedded into the chutes. The chuck is characterized in that a clamping chuck body is arranged on the upper end face of the power chuck body; rectangular grooves corresponding to the chutes are uniformly distributed on the lower end face of the clamping chuck body along the radial direction; a push claw is arranged in each rectangular groove; the lower end face of each push claw is attached to the upper end face of each bottom claw of the power chuck body; each push claw is fixed with each bottom claw through a connecting piece; a rotating groove is formed on the upper end face of each push claw, which is close to the inner end; swing rod component installation cavities are formed on the chuck body positioned above the rotating grooves; each swing rod component comprises a swing rod and a pair of swing rod seats; a clamping end is arranged on the head of the swing rod; a rotating shaft is arranged in the middle of the swing rod; and a rotating circular shaft is arranged at the bottom of the swing rod. By the new swing rod axial buckling chuck, the problem that the traditional power chuck difficultly clamps a workpiece with a complicated structure is solved; and the workpiece is axially clamped, and the application range of the traditional power chuck is expanded.
Description
Technical field
The present invention relates to a kind of fixture, particularly a kind of chuck of the workpiece of fastening vertically.
Background technology
Chuck is on lathe, to be used for the mechanical device of clamping work pieces, is fixture important in machining, and common chuck adopts radial clamping mode clamping work pieces, but for complex structure or the special part of profile, as conical bevel gear, can not adopt radial clamping.
Summary of the invention
The present invention, for fear of the weak point of prior art existence, provides a kind of chuck of the workpiece of fastening vertically.
The technical problem that the present invention solves adopts following scheme:
The axial fastening chuck of a kind of oscillating rod type, comprises power chuck body, and described power chuck body upper surface is radially evenly equipped with 3 chutes, and described chute is embedded with the end pawl being slidably matched; Its design feature is,
An expansion chuck body that is arranged on power chuck upper surface is set, the lower surface of described expansion chuck body is radially evenly equipped with the rectangular channel corresponding with power chuck body upper hopper chute, corresponding to each rectangular channel, in it, being provided with one pawls, at the bottom of described lower surface of pawling and power chuck, pawl upper surface is pasted merga pass connector and is fixed, described in pawl and be provided with rotation slot near inner upper surface; On the chuck body being positioned at above rotation slot, be provided with oscillating bar assembly installation cavity, described oscillating bar assembly has three groups, every group of a pair of swing rod that comprises a fork, is installed in fork both sides, the head of described fork has the bare terminal end of holding workpiece, middle part is provided with the rotating shaft being rotatably assorted with swing rod, and bottom is provided with the rotation circular shaft being rotatably assorted with the rotation slot of pawling.
Design feature of the present invention is also:
Described pawling is provided with the helical tooth field of conjugate action with end pawl, and will be pawled and be fixed with end pawl by sunk screw.
Described swing rod is fixed in the T-shaped groove of chuck body.
Described fork bare terminal end has a round and smooth arc clamping face.
Compared with the prior art, beneficial effect of the present invention is embodied in:
The present invention has overcome the difficult problem that when Workpiece structure is complicated, traditional power chuck is difficult to clamping, provides a kind of new oscillating rod type axial fastening chuck, by axial grip mode holding workpiece, has expanded the range of application of traditional power chuck; The part of for example some tapers, because of its special structure, make traditional power chuck be difficult to it to realize radial clamping, and the present invention can realize the clamping to these parts by the axial fastening conical part of the arc clamping face of bare terminal end.
