Abstract

The utility model relates to a pair of quick action flat pliers, which is formed by the way that a quick-action device is additionally arranged on the upper cover part of the Q12160 machine flat pliers which is the country approved product. The utility model comprises a pliers frame, an upper cover arranged on the pliers frame, a nut embedded in an upper cover body, a leading screw penetrating through the upper cover and the nut, a baffle ring fixed on one end of the pliers frame and a positioning pin skewered on one end of the leading screw, and the flat pliers is provided with a quick-action device. The half-round nut can be caused to enhance and fall by turning a raising and falling screw rod which is perpendicularly arranged on the surface of the upper cover, realizing quick action and slow action of the flat pliers. The work efficiency can be increased by 10-20 times. The utility model has the advantages of convenient operation and low cost, and is the ideal flat pliers of the present accessory factory for machine tools.

Description

Quick dynamic flat plicers
But the present invention relates to a kind of machine vise of snap-action.
According to the prior art data, known machine vise, because simple use screw mandrel and nut engagement are rotated and are produced the loam cake displacement, the platen restriction makes crank can only rotate half cycle at every turn in addition, thereby making the adjustment of length between vices size can only be the unit frequent variations according to screw mandrel and nut screw thread, roll adjustment speed is slow, work efficiency is low, can not adapt to the lathe development need.
But the objective of the invention is to design a kind of can slow motion and the flat-nose pliers of snap-action, overcoming with the screw thread is all shortcomings of flat-nose pliers of unit roll adjustment; The present invention from theory structure make flat-nose pliers formed that roll adjustment speed is fast, work efficiency is high (improving 10-20 doubly) easy to operate, use characteristics such as flexible.
Flat-nose pliers of the present invention is to set up the snap-action device at national approved product Q12160 machine vise upper cover part to form.Its snap-action device is made up of as Fig. 1 pressing plate (4), panel nut (5), handle (6), stop nut (7), brute spring (13), lifting screw (8). Fig. 2. and Fig. 3.
Pressing plate (4) is a figure metallic plate, its central part has a circular hole, respectively there is a hole in circular hole both sides metal-sheet edges portion, the organizine hole is fixed in pressing plate (4) on the top, nut (3) two side with plate screw (12), be used for realizing the ascending, descending campaign that nut (3) is whole, as Fig. 1. Fig. 2. Fig. 3.
Lifting screw (8) is the round metal screw mandrel that an end has major part.One end penetrates by loam cake (2) silk hole through pressing plate (4) medium pore and protrudes loam cake (2) upper surface installation stop nut (7), handle (6), the other end is fixing with panel nut (5) and pressing plate (4), be used for transmitting the rotating torque of handle (6), as Fig. 1. Fig. 2.
Stop nut (7) according to lifting screw (8) rotation, accurately limits nut (3) ascending, descending distance between handle (6) and loam cake upper surface, realize snap-action, and the minimum of handle during slow motion (6) is changeed distance.
Handle (6) bolt or slightly, skewer is fixed in lifting screw (8) one terminations, can make turning moment pass to the operation of elevating lever (8) when being used for realizing snap-action, as Fig. 1, Fig. 2.
During work, rotary handle (6) makes nut (3) decline separate with screw mandrel (9), and horizontal slip loam cake (2) is realized snap-action.Reverse rotation handle (6) rises and the identical slow motion of realizing of screw mandrel (9) nut (3).
The scheme that realizes snap-action also can be in handle (6) below according to lifting screw (8) device brute spring (13), and processing loam cake (2) silk hole is that through hole, pressing plate (4) medium pore are for the silk hole, as Fig. 3.
Accompanying drawing is represented:
