Abstract

The utility model relates to the technical field of a processing tool, in particular to a special fixture for processing a die-forged chain sliding rack. The fixture is provided with a hollow rotating disc for depositing the sliding rack; a clamp arm and a clamping block are axially arranged at the rotating disc; the clamp arm is provided with an opening, a clamping end of the sliding rack is fixed on the rotating disc by the clamping block, and a processing end of the sliding rack is penetrated in the clamp arm by the opening; the clamping block is flexibly connected with a clamp nail and the rotating disc; a rotating nail is arranged at the middle part of the clamping block; the contact surface between the rotating disc and the sliding rack is arranged to incline 1 to 3 DEG downwards, and a positioning pole is arranged on the contact surface between the rotating disc and the sliding rack; fixing nails are arranged at the side arms of the clamp arm, namely the fixing nails are symmetrically arranged at the two sides of the clamp arm; an axial clamping nail is arranged on the cross section of the clamp arm far away from the rotating disc; at least two balancing blocks are fixedly connected on the rotating disc; an included angle between each balancing block and the clamping block is completely the same, the clamping force is strong and the utilization is convenient.

Description

Dropforged chain balladeur train Special Fixture for Machining

Technical field

The utility model relates to the machining tool technical field, especially a kind of dropforged chain balladeur train processing specific purpose tool.

Background technology

At present, many will hanging sent weight in large-scale workshop, so use carrier chain, carrier chain will be installed on the balladeur train, thereby the design of balladeur train is particularly important, on the processing of balladeur train, require also very high, add at balladeur train and need use anchor clamps man-hour, mostly existing anchor clamps are general, to the processing inconvenience of balladeur train, it is insecure to step up power, processing difficulties.

Summary of the invention

The technical problems to be solved in the utility model is: a kind of dropforged chain balladeur train Special Fixture for Machining is provided.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of dropforged chain balladeur train Special Fixture for Machining, the rotating disc that the hollow of placing balladeur train is arranged, rotating disc axially is provided with card arm and clamp, the card arm has opening, on the rotating disc by the fixing pinching end of balladeur train of clamp, be installed with the processing end of balladeur train in the card arm by opening, clamp is by bail and rotating disc active link, the middle part of clamp is provided with and screws nail, and the contact-making surface of rotating disc and balladeur train is set to downward-sloping 1 °～3 °.

Further the contact-making surface of rotating disc and balladeur train is provided with reference column, the side arm of card arm is provided with staple, the both sides that are arranged on the card arm of staple symmetry, the card arm is provided with axial chucking nail away from the cross section of rotating disc, at least be fixedly connected with two balance weights on the rotating disc, balance weight is all identical with angle between the clamp.

The beneficial effects of the utility model are, dropforged chain balladeur train Special Fixture for Machining of the present utility model, and that steps up is effective, processes easily.
