Abstract

The utility model provides a pipe work piece fixture device, belong to the anchor clamps field, the problem of current pipe anchor clamps exist is solved, it contains the base, set up a square fretwork at the base intermediate position, it is trapezoidal clamping piece to set up a plurality of cross sections in the fretwork, set up splint respectively in the both sides of a plurality of clamping pieces, be used for a plurality of clamping pieces of centre gripping, the lead screw of perpendicular to splint is set up on the outside surface of every splint, the one end and the circumferential direction of splint along the lead screw of lead screw are connected, in the screw that lead screw setting corresponds with the lead screw on the base, through rotary screw control splint advance and retreat, still be provided with two locating levers parallel with the lead screw on the outside surface of every splint, the one end and the splint fixed connection of locating lever, in the locating hole that locating lever setting corresponds with the locating lever on the base, it is rotatory that the locating lever can prevent that splint from following the lead screw, the utility model is used for the centre gripping pipe.

Description

Circular pipe workpiece grip device

Technical field

The utility model belongs to field of fixtures, is specifically related to a kind of circular pipe workpiece grip device.

Background technology

Existing pipe fixture is in order to clamp the circular pipe workpiece of different-diameter, the clamping face of fixture is plane or differential of the arc face, a linear contact lay is only had between fixture and pipe, lifting surface area is minimum, corresponding friction is also minimum, causes being pressed from both sides pipe instability, even if it is also undesirable to increase chucking power effect, chucking power is excessive also can make thinner pipe produce plastic deformation, has a strong impact on crudy.

Summary of the invention

The purpose of this utility model is the problems referred to above existed to solve existing pipe fixture, and provide a kind of circular pipe workpiece grip device, its technical scheme is as follows:

A kind of circular pipe workpiece grip device, it comprises pedestal, a square hollow out is set in pedestal centre position, in hollow out, arrange multiple cross section is trapezoidal intermediate plate, clamping plate are set respectively in the both sides of multiple intermediate plate, be used for clamping multiple intermediate plate, at the outer surface of each clamping plate, a leading screw perpendicular to clamping plate is set, one end of leading screw and clamping plate are rotationally connected along the circumference of leading screw, leading screw is arranged in screw corresponding with leading screw on pedestal, control clamping plate by rotating threaded shaft to retreat, two backstays parallel with leading screw are also provided with at the outer surface of each clamping plate, one end of backstay is connected with Boards wall, backstay is arranged in locating hole corresponding with backstay on pedestal, backstay can prevent clamping plate from rotating with leading screw.

The beneficial effects of the utility model are: the position of multiple intermediate plate can adjust according to the external diameter of pipe, each intermediate plate and pipe are with linear contact lay, friction is made to increase several times, the friction that each intermediate plate can double, be easy to make to be pressed from both sides pipe and keep stable, be particularly suitable for clamping thin-wall circular tube.
