Technical Field

The utility model relates to a machine tooling field, in particular to lever cylinder is used to work piece is fixed.

Background

When the lever cylinder is used for fixing a workpiece, because the compression bar of the lever cylinder is made of steel, an indentation is easily left on the surface of the workpiece, the workpiece is scrapped due to the indentation, in addition, a large amount of time is needed for adjusting the height of the compression bar every time, and a large amount of workpieces are needed for testing.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a fixed lever cylinder that uses of work piece has the advantage of protection workpiece surface, reduction work piece disability rate, convenient change.

The above technical purpose of the present invention can be achieved by the following technical solutions:

the utility model provides a lever cylinder is used to work piece is fixed, based on square work piece, its characterized in that: the square workpiece positioning device comprises a placing plate, two lever cylinders and a cushion block, wherein placing grooves are formed in the front side and the rear side of the top of the placing plate, the lever cylinders are arranged in the two placing grooves respectively, and the square workpiece is positioned between the two lever cylinders;

every the lever cylinder all includes the depression bar, and every depression bar keeps away from one side bottom of lever cylinder and all is equipped with the cushion, every the standing groove that the vertical cross-section is the T type is all seted up to the bottom of depression bar, every the cushion is inlayed respectively in the standing groove of the bottom of lever cylinder, every the vertical cross-section of cushion all is the T type, every all leave the cavity between the top of cushion and the bottom of standing groove, every all be equipped with the spring of a plurality of vertical forms in the cavity.

The preferred scheme is as follows:

preferably: the cushion block is a transparent plastic block. The transparent plastic block can play a role in protecting the workpiece.

Preferably: the bottom of the cushion block is provided with a plurality of semicircular grooves. The semicircular groove can play a role in increasing friction force.

Preferably: the height of the cushion block extending out of the pressure rod is half of the height of the cavity. When being extruded, can have sufficient space to contract, but because the high reason of cushion, the cushion can not be totally contracted, and is equipped with the spring, can make things convenient for the cushion to reset, and the spring after being extruded still possesses a silk elasticity, can prevent that the work piece from having the indentation because too hard extrusion.

Preferably: every the top left and right sides of standing groove all is equipped with the briquetting, the briquetting passes through the bolt and is connected with standing plate top rotation. Utilize the briquetting to compress tightly the lever cylinder, when the lever cylinder needs to be changed, rotate the briquetting, can take out the lever cylinder, the convenient change.

To sum up, the utility model discloses following beneficial effect has:

1. the cushion block is arranged, so that the effect of protecting the workpiece can be achieved;

2. through the setting of briquetting, can play the effect of conveniently changing the lever cylinder.

The utility model has the advantages of protect the workpiece surface, reduce the scrap rate of the workpiece, and facilitate the replacement.

In the figure, 1, a square workpiece; 2. placing the plate; 3. a lever cylinder; 4. cushion blocks; 5. a pressure lever; 6. a spring; 7. briquetting; 8. and (4) bolts.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

In which like parts are designated by like reference numerals. It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "bottom" and "top," "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.

As shown in fig. 1-2, a lever cylinder for fixing a workpiece is based on a square workpiece 1, and comprises a placing plate 2, two lever cylinders 3 and a cushion block 4, wherein placing grooves are respectively arranged on the front side and the rear side of the top of the placing plate 2, the two lever cylinders 3 are respectively arranged in the two placing grooves, and the square workpiece 1 is positioned between the two lever cylinders 3;

every lever cylinder 3 all includes depression bar 5, and every depression bar 5 keeps away from one side bottom of lever cylinder 3 and all is equipped with cushion 4, every the standing groove that the vertical cross-section is the T type is all seted up to depression bar 5's bottom, every cushion 4 inlays respectively in the standing groove of lever cylinder 3's bottom, every cushion 4's vertical cross-section all is the T type, every all leave the cavity, every between the top of cushion 4 and the bottom of standing groove all be equipped with the spring 6 of a plurality of vertical forms in the cavity.

The cushion block 4 is a transparent plastic block. The transparent plastic block can play a role in protecting the workpiece.

And a plurality of semicircular grooves are formed in the bottom of the cushion block 4. The semicircular groove can play a role in increasing friction force.

The height of the cushion block 4 extending out of the compression bar 5 is half of the height of the cavity. When being extruded, can have sufficient space to contract, but because the high reason of cushion 4, cushion 4 can not be totally contracted, and is equipped with spring 6, can make things convenient for cushion 4 to reset, and spring 6 after the extrusion still possesses a silk elasticity, can prevent that the work piece from having the indentation because too hard extrusion.

Every the top left and right sides of standing groove all is equipped with briquetting 7, briquetting 7 passes through bolt 8 and is connected with standing plate 2 top rotation. Utilize briquetting 7 to compress tightly lever cylinder 3, when the lever cylinder 3 that needs to be changed, rotate briquetting 7, can take out lever cylinder 3, the convenient change.

The specific implementation process comprises the following steps:

put into two standing grooves of placing board 2 with two lever cylinders 3 respectively, rotate briquetting 7, tightly push down the cylinder, rotatory bolt 8 simultaneously, and then it is fixed with briquetting 7, place the work piece on placing board 2, after adjusting the position, the telescopic link extension of cylinder, tightly push down the work piece, when cushion 4 is by the extrusion, can have sufficient space to contract, but because the reason of cushion 4 height, cushion 4 can not be totally by the shrink, and be equipped with spring 6, can make things convenient for cushion 4 to reset, and spring 6 after being extruded still possesses a silk elasticity, can prevent that the work piece from having the indentation owing to too hard extrusion.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
