Abstract
The utility model discloses a chuck, which comprises a base. The upper end of the base is connected with a sliding seat; the sliding seat is respectively and glidingly connected with a left sliding plate and a right sliding plate; end parts of both sides of the sliding seat are respectively connected with a sliding seat end plate; the middle of each sliding seat end plate is provided with a through hole; a screw rod is rotatablely arranged in the through holes; both sides of the screw rod are respectively provided with a left-hand thread and a right-hand thread, and a left nut and a right nut are correspondingly arranged; the left nut is fixedly connected with the left sliding plate; the right nut is fixedly connected with the right sliding plate; the left sliding plate and the right sliding plate are respectively provided with a jaw; each jaw is of a V-shaped structure; both sides of the inner side of the corresponding jaw are respectively provided with a jaw inner base plate; and both sides of the outer side of the corresponding jaw are respectively provided with a jaw outer base plate. As the jaws arranged on chuck are respectively of the V-shaped structure, when clamping is performed, the two jaws can be in four-point contact with a workpiece, and a fastening effect is good. Moreover, the jaw outer base plate and the jaw inner base plate arranged on the corresponding jaw are respectively made of a copper material, and therefore, the workpiece is effectively prevented from being crushed. The chuck is simple in structure and can be easily realized.
Description
Technical field
The utility model relates to a kind of chuck.
Background technology
Need to select some chucks to come holding workpiece on 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, and by two some clamping work pieces, its fastening effect is relatively poor, can not effectively clamp due to only; And can clamping the scroll chuck of larger workpiece often cost is higher, and easily damage the surface of workpiece.
The utility model content
The purpose of this utility model is for the problems referred to above, and a kind of chuck is 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 purpose of this utility model is to be achieved through the following technical solutions:
a kind of chuck, comprise base, described base upper end is connected with sliding seat, slidably connect respectively left skateboard on described sliding seat, right slide plate, and the end, both sides of sliding seat all is connected with the sliding seat end plate, in the middle of described sliding seat end plate, the place has through hole, 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, be provided with claw on described left skateboard and right slide plate, described claw is v-shaped structure, its inboard both sides all are equipped with backing plate in claw, and the both sides in its outside all are equipped with the outer backing plate of claw.
Further, have installing hole on 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, in the outer backing plate of described claw and claw, backing plate is made by copper product, 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 described sliding seat.
The beneficial effects of the utility model are, the claw that arranges on 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 in the outer backing plate of the claw that arranges on claw and claw, backing plate is made by copper product, thereby effectively avoid crushing workpiece, simple in structure, be easy to realize.
