Abstract

Provided is a mechanical floating support used for a combination fixture in the mechanical industry. The floating support comprises a floating support body, a floating support shaft, a locking oblique block, a locking screw, a bolt, a reset spring A and a reset spring B. When a workpiece is fixed by the combination fixture, in order to reduce the workpiece shock and prevent the workpiece deformation in a mechanical machining, the floating support can be placed below the workpiece before being machined. In addition, by means of the compression deformation of the reset spring B, the floating support shaft can automatically contact with the workpiece closely. The locking screw is tuned and the locking oblique block is pushed, so that a protruded edge of the locking oblique block can slide into a groove of the floating support main shaft. By means of the compression deformation of the reset spring A, an oblique surface of the locking oblique block can be attached to an oblique surface of the floating support main shaft tightly all the time. Therefore, a supporting force in the vertical direction can be provided for the bottom surface of the machined workpiece, and machining precision and quality of the machined workpiece are also improved.

Description

Float support

Technical field:

The mechanical floating that the invention belongs to built-up jig in a kind of machinery industry supports, and belongs to the technical field of the built-up jig apparatus structure of Aided Machine processing.

Background technology:

In machining, float support provides a vertical supplemental support of self-adjusting for workpiece, and it can reduce Workpiece vibration and prevent workpiece deformation in machined.At present, the Pneumatic floating on the market supports and hydraulic floating supports convergence maturation, but needs the equipment such as pneumatic means and hydraulic means to cooperate, and cost is high, and it is large to take up room, and to the workpiece of some mounting condition harshness, accommodative facility is inadequate.

The present invention just provides a kind of self-adjusting vertical float and supports, owing to be mechanical float support, cost is low, and it is little to take up room, and uses independently, and is convenient, flexible adjustment.

Summary of the invention:

The purpose of this utility model provides a kind of float support and is used for solving the problem that background technology is mentioned, and it provides a vertical supplemental support of self-adjusting for workpiece.

A kind of float support of built-up jig comprises: float support main body (1), float support axle (2), locking skewback (3), back-moving spring A (4), thin nut (5), lock-screw (6), back-moving spring B (7), bolt (8) is characterized in that

Described float support main body (1) is special-shaped slush casting body, and 2 microscler locating slots (1-101) are arranged at its bottom, make being rigidly connected and linear regulation of bolt and built-up jig by microscler locating slot (1-101);

Described float support axle (2) is cylinder, straddle on the back-moving spring B (7), because can making float support axle (2), the elastic force of back-moving spring B (7) floats in vertical direction, by rotation lock screw (6), promote locking skewback (3), the fin of locking skewback (3) is slided in the groove (2-101) of float support main shaft, compression by back-moving spring A (4) can allow the inclined-plane of locking skewback and the inclined-plane (2-102) of float support main shaft be adjacent to, like this, can lock float support axle (2) in vertical direction, play the vertical support effect to workpiece bottom;

Described thin nut (5) plays the effect of locking tight lock screw (6), prevents from coming off.

The utility model can lack Workpiece vibration and prevent workpiece deformation by alkali in machined.Owing to be mechanical float support, cost is low, and it is little to take up room, and uses independently, and is convenient, flexible adjustment.

The specific embodiment:

[0012] when the two ends of workpiece be combined anchor clamps fixing after, before processing, be placed on float support below the workpiece and utilize the compression of back-moving spring B (7), make automatically close contact workpiece of float support axle (2), float support axle (2) is the distance of automatic floating 40mm in vertical direction, automatically after adjusting, rotation lock screw (6), promote locking skewback (3), the fin of locking skewback (3) is slided in the groove (2-101) of float support main shaft, compression by back-moving spring A (4) can allow the inclined-plane of locking skewback and the inclined-plane (2-102) of float support main shaft be adjacent to, make its locking, fixing float support main shaft (2), at last, float support main body (1), 2 microscler locating slots (1-101) are arranged at its bottom, can make on its any position that is fixed on the built-up jig soleplate with bolt by locating slot (1-101).
