Abstract

The utility model discloses a safety check device preventing a workpiece from being flied out. The safety check device is installed on a three-jaw chuck of a machine tool and comprises a body which is a circular check block. Three grooves are machined in the circumferential direction of the body to correspond to three clamping jaws on the three-jaw chuck of the machine tool, wherein the angle between every two grooves is 120 degrees. A circular boss is arranged in the center of the inner side face of the circular check block, and a threaded hole and a fixing bolt are arranged in the center of the circular check block. When the safety check device preventing the workpiece from being flied out, the circular check body is placed to the three-jaw chuck to be connected with an inner hole of the three-jaw chuck, the clamping claws are inserted into the three grooves at the same time, the fixing bolt is adjusted, the distance for the clamping jaws for clamping the workpice can be ensured, therefore, axial displacement of the workpiece in the machining process is avoided, potential safety hazards are avoided, and machining efficiency is greatly improved.

Description

A kind of safe stopping device that prevents that workpiece from flying out

Technical field

The utility model relates to safety device, particularly a kind of for the safe stopping device that workpiece flies out that prevents on machine tool.

Background technology

In field of machining, engine lathe is indispensable equipment at present, just current each mechanic factory workers, and small size lathe C6250 or L-5 are used general.In operating process, we find; usually can encounter such problem during the working shaft-like part: axial workpiece is when roughing; general adopt folder one top processing method; when the excircle of workpiece size is less than the situation of scroll chuck endoporus; larger due to smear metal consumption, feed during roughing; workpiece often can produce displacement to the chuck direction in process, therefore can cause workpiece fly out and safety, quality accident occur.This problem has directly had influence on safety in production, product quality and the production cycle of enterprise, if therefore do not solve the problem of existence, will be difficult to meet current safety requirements and processing tasks requirement per month.

Tradition clamping method existing problems:

1,, when occurring that the excircle of workpiece size is less than the situation of scroll chuck endoporus, folder one apical axis can't solve to displacement;

2, because the lathe spindle endoporus is greater than the scroll chuck endoporus, can't be in main shaft the Fast Installation stopping device.

Summary of the invention

The purpose of this utility model is to design a kind of safe stopping device that prevents that workpiece from flying out, be arranged on scroll chuck, avoid the workpiece axial displacement occurred in conventional processes, stopped potential safety hazard, guarantee normally carrying out of production, thereby improved working (machining) efficiency.

For achieving the above object, the technical solution of the utility model is:

A kind of safe stopping device that prevents that workpiece from flying out, be arranged on machine tool three-jaw chuck, it is characterized in that, comprises, body, be a rounded stops, along minute three grooves of processing such as circumferential every 120 degree angles, three claws on corresponding machine tool three-jaw chuck respectively; Rounded stops medial surface central authorities establish round boss; Screw and a set bolt are established in the rounded stops center.

The beneficial effects of the utility model:

1, solve workpiece and added the axial displacement problem in man-hour

2, stopped the safety problem that workpiece flies out adding axial displacement in man-hour

The accompanying drawing explanation

The structural representation that Fig. 1 is rounded stops in the utility model embodiment.

The A-A cutaway view that Fig. 2 is Fig. 2.

The structure cutaway view that Fig. 3 is the utility model embodiment.

The specific embodiment

Referring to Fig. 1～Fig. 3, a kind of safe stopping device that prevents that workpiece from flying out of the present utility model, be arranged on machine tool three-jaw chuck, comprise, body 1, it is a rounded stops, along minute three

grooves

11,12,13 of processing such as circumferential every 120 degree angles, three claws on corresponding machine tool three-jaw chuck respectively; Rounded stops medial surface central authorities establish round boss 14; Screw 15 and a set bolt 2 are established in the rounded stops center.

During use, body 1 rounded stops is positioned on scroll chuck, with the scroll chuck endoporus, be connected, three

grooves

11,12,13 insert in claw simultaneously, regulate set bolt 2, can guarantee the distance of claw holding workpiece, so just solved the axial displacement of workpiece in process, stop potential safety hazard, greatly improved working (machining) efficiency.

Claims

1. a safe stopping device that prevents that workpiece from flying out, be arranged on machine tool three-jaw chuck, it is characterized in that, comprises, body, be a rounded stops, along minute three grooves of processing such as circumferential every 120 degree angles, three claws on corresponding machine tool three-jaw chuck respectively; Rounded stops medial surface central authorities establish round boss; Screw and a set bolt are established in the rounded stops center.
