Abstract
The utility model belongs to the technical field of design of a machine tool fixture, and relates to a quick pressing device. The quick pressing device comprises a screw [1] and a pressing plate [2], wherein the screw [1] is fixed to a tool base [4]; a distance from the lower surface of the end of the screw to the upper surface of a work piece is required to be 1-2 mm higher than the height of the pressing plate [2]; a U-shaped groove is required to be formed on the pressing plate [2]; a centre at a circular-arc end of the groove passes through a centre of the pressing plate [2]; the width of the groove is 0-1 mm greater than the diameter of the screw [1]; a contact portion of the screw [1] and the pressing plate [2] is square; the height of the square portion is 2-5 mm greater than the height of the pressing plate [2]; the square portion of the screw [1] is placed in the U-shaped groove of the pressing plate [2]. The quick pressing device disclosed by the utility model can realize quick pressing and loosening of parts simply by using the screw and a washer.
Description
Technical field
The utility model belongs to Machine Tool Fixture Design technical field, relates to a kind of fast compressing device.
Background technology
Along with the continuous complexity of Machine Tool design structure, the operation of each required processing of clamping is also more and more, add the time in process in order to reduce parts fixation at whole machine, need to pursue Fast Installation and the dismounting of part, design different fast compressing devices according to workpiece multi-form.
Summary of the invention
The object of the invention is: propose a kind of fast simple hold down gag.
Technical scheme of the present invention is: a kind of fast compressing device, this device comprises screw 1 and pressing plate 2, screw 1 is fixed on tooling base 4, screw termination lower surface need to be than the high 1mm-2mm of the height of pressing plate 2 to the distance of workpiece surface, on pressing plate 2, need to offer a U-shaped groove, the center of pressing plate 2 is crossed at the arc end center of groove, the width of groove is than the large 0-1mm of screw 1 diameter, the position that described screw 1 contacts with pressing plate 2 is square, the large 2mm-5mm of height of projected square part aspect ratio pressing plate 2, the U-shaped groove of pressing plate 2 is put at the square position of screw 1.
Advantage of the present invention is: the utility model only adopts screw and packing ring, can realize the fast-holding of part and unclamp.

Detailed description of the invention
Below the utility model is described in further details.
A kind of fast compressing device, this device comprises screw 1 and pressing plate 2, screw 1 is fixed on tooling base 4, screw termination lower surface need to be than the high 1mm-2mm of the height of pressing plate 2 to the distance of workpiece surface, on pressing plate 2, need to offer a U-shaped groove, the center of pressing plate 2 is crossed at the arc end center of groove, the width of groove is than the large 0-1mm of screw 1 diameter, the position that described screw 1 contacts with pressing plate 2 is square, the large 2mm-5mm of height of projected square part aspect ratio pressing plate 2, the U-shaped groove of pressing plate 2 is put at the square position of screw 1.
The course of work of the present utility model is as follows:
Screw 1 is fixed in frock in advance, then pressing plate 2 is overlapped as in screw 1 by U-shaped groove, by turning handle 3, pressing plate 2 is rotated, U-shaped groove in pressing plate 2 can drive screw 1 square position rotation, screw 1 is because the effect of screw thread moves down, screw 2 is pressed on pressing plate 2, and pressing plate 2 is pressed against on workpiece, reaches the fast-holding of workpiece.Otherwise rotation can reach quick-release object.Because screw 1 head lower surface is 1mm-2mm to pressing plate 2 upper level, only need rotation 1/2nd circles to realize so general and compress and dismounting.
