Abstract
The invention discloses a chuck, which comprises a base; the upper end of the base is connected with a sliding seat; the sliding seat is respectively connected with a left sliding plate and a right sliding plate in a sliding way; and ends at two sides of the sliding seat are connected with sliding seat end plates; through holes are formed in the middle of the sliding seat end plates and are internally provided with lead screws in a rotating way; left threads and right threads are respectively arranged at two sides of the lead screws; a left nut and a right nut are correspondingly arranged, and the left nut is fixedly connected with the left sliding plate; the right nut is fixedly connected with the right sliding plate; jack catches are arranged on the left sliding plate and the right sliding plate and are of V-shaped structure; jack catch inner base plates are installed at two inner sides of each jack catch; and jack catch outer base plates are installed at two outer sides of each jack catch. According to the invention, the jack catches arranged on the chuck are of the V-shaped structure; when clamping, the two jack catches can lead four points to contact a work piece and realize good fastening effect; the jack catch inner base plates and the jack catch outer plates arranged on the jack catches are all made of copper; and in the way, and the chuck can effectively avoid damage to the work piece when clamping, and is simple in structure and easy to implement.
Description
Technical field
The present invention relates to a kind of chuck.
Background technology
Need to select some chucks to come holding workpiece at some welding benches, commonly used have two pawls and a three-jaw self-centering chuck.At present, existing two-jaw(ed)chuck is when the larger workpiece of clamping, because only by two some clamping work pieces, its fastening effect is relatively poor, can not effectively clamp; And can clamping the scroll chuck of larger workpiece often cost is higher, and easily damage the surface of workpiece.
Summary of the invention
The object of the invention is to for the problems referred to above, a kind of chuck be provided, its have simple in structure, be easy to realize, can effectively clamp large-size workpiece and the characteristics of easy damaged surface of the work not.
The objective of the invention is to be achieved through the following technical solutions:
A kind of chuck, comprise base, described base upper end is connected with sliding seat, slidely connect respectively left skateboard on the described sliding seat, right slide plate, and the end, both sides of sliding seat all is connected with the sliding seat end plate, the place has through hole in the middle of the described sliding seat end plate, the rotating screw mandrel that is provided with in it, the both sides of described screw mandrel are respectively arranged with left hand thread, right-handed thread, and correspondence is provided with left screw, right screw, described left screw is fixedly connected with left skateboard, described right screw is fixedly connected with right slide plate, is provided with claw on described left skateboard and the right slide plate, and described claw is v-shaped structure, its inboard both sides all are equipped with backing plate in the claw, and the both sides in its outside all are equipped with the outer backing plate of claw.
Further, have installing hole on the described base, can conveniently be fixed on the workbench that needs.
Further, the end, both sides of described screw mandrel is square structure, and is connected with crank.
Further, backing plate is made by copper product in the outer backing plate of described claw and the claw, avoids crushing workpiece.
Further, described left skateboard and right slide plate all are connected with slide block, have the chute that matches with slide block on the described sliding seat.
Beneficial effect of the present invention is, the claw that arranges on the described chuck is v-shaped structure, during clamping, workpiece all is close on the both sides of claw, and two claws can reach four some contact workpiece, and are fastening effective, and backing plate is made by copper product in the outer backing plate of the claw that arranges on the claw and the claw, thereby effectively avoid crushing workpiece, simple in structure, be easy to realize.
