Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a milling vise clamping device,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a milling vise for tightening a workpiece, and more particularly to a milling vise clamping apparatus for clamping a workpiece in accordance with rotation of a rotating screw, will be.

Generally, in order to machine a workpiece, the state of the workpiece is fixed by using a vice or the like, and the workpiece is processed by a cutting tool or a milling cutter. The vise is a tool for clamping a workpiece, such as a box vise, a legged vise, a milling vise, and the like, and is usually fixed on a work table for machining a workpiece.

The structure of such a vise is, for example, a workpiece milling vise of Laid-Open Publication No. 1999-009871.

1 and 2, a conventional work milling vise is composed of a main body 1 which is detachably fixed to a work table and constitutes a lower portion thereof, and two vise jaws A fixed jaw 2 and a moving jaw 3. The fixed jaw 2 and the moving jaw 3 are in contact with or spaced from each other to fix the workpiece.

A hollow screw 6 and a rotating screw 7 for moving the moving jaw 3 back and forth are provided on opposite sides of the moving jaw 3 that are not in surface contact with the fixed jaw 2. The hollow screw 6 and the rotary screw 7 are connected to each other by screwing and the other end of the rotary screw 7 extends outward and is rotatably supported by the support bracket 10.

A guide rail 9 is formed on the upper side of the main body 1 so as to move the moving jaw 3. A stationary ring 8 is provided on the outer periphery of the rear end of the rotating screw 7 passing through the supporting bracket 10, The fixing ring 8 and the rotary screw 7 are fixed by the fixing pin 11. [

However, in the conventional cooperating milling vise, the fixing ring 8 is fitted and fixed to the outer periphery of the rear end of the rotating screw 7 so that the rotating screw 7 supported by the supporting bracket 10 is rotated back and forth without being moved in the axial direction Since the outer peripheral surface of the stationary ring 8 having such a structure is not provided with a function of displaying the amount of rotation, the rotating screw 7 is rotated according to the skill of the operator Since the clamping pressure of the massive workpiece clamped between the fixed jaw (2) and the moving jaw (3) can not be maintained constantly each time, the machining dimensions of each large workpiece are slightly distorted, There was a problem.

That is, when the tightening pressure of the fixed jaw 2 and the moving jaw 3 is strong, the work can not be overcome, and the workpiece is finely pushed to the upper portion, If the tightening pressure is low, the workpiece clamped between the stationary jaw (2) and the moving jaw (3) may not be able to maintain the accuracy. there was.

It is an object of the present invention to solve the problems in the prior art, and it is an object of the present invention to eliminate the error caused by a change in the tightening pressure when rotating a rotary screw so that a large number of workpieces are clamped between a fixed jaw and a moving jaw Which is capable of maintaining uniform machining accuracy of a large number of workpieces while preventing a safety accident caused by deviation of the workpiece.

According to another aspect of the present invention, there is provided an apparatus for confirming the tightening amount of a milling vise, comprising: a fixing jaw fixed to an upper side of a guide rail; A fixed ring coupled to the outer periphery of the rear end of the rotary screw so as to be rotated back and forth without rotating the rotary screw from the support bracket in the axial direction; The present invention relates to a milling vise having a tightening amount confirming means for confirming and adjusting the tightening amount of a fixed jaw and a moving jaw,
The fastening amount confirming means,
A tightening amount display unit formed of a combination of six equal numbers and a graduation at a predetermined interval on the outer circumferential surface of the stationary ring and capable of confirming the tightening amount of the fixed jaw and the moving jaw by the rotation of the rotating screw,
And a reference point display unit formed at the center of the upper surface of the support bracket to provide a reference point for checking whether the rotation screw is rotated or not rotated through the tightening amount display unit,
Wherein the fixing ring and the rotating screw are coupled by an adjusting bolt which is passed through one side circumferential screw hole of the stationary ring and is pressed to one side of the outer circumferential surface of the rear end of the rotating screw,
The adjusting bolt is formed with a groove around which a worker can loosen or tighten by a hand and a groove into which a tool is inserted at the center of the upper surface of the head.
In another embodiment, the retaining ring and the rotary screw of the present invention are characterized in that the retaining ring and the rotary screw are coupled by an inner circumferential surface of the stationary ring and a pair of male and female threads formed corresponding to the outer circumferential surface of the rear end of the rotary screw.
