For realizing above-mentioned technical purpose, the scheme that the utility model provides is: a kind of scratch diskette comprises disk body and tries to get to the heart of a matter; Wherein, Disk body and try to get to the heart of a matter between vacuum-sealed cavity is set, disk body is provided with gastight joint by stretching into vacuum-sealed cavity outward, disc surfaces evenly is covered with the suction hole that is communicated with vacuum-sealed cavity; Disk body is provided with the magnetic force piece; Disc surfaces is provided with geometrical clamp.

And gastight joint is to be threaded with disk body.

And, inhale the upper end, hole vacuum cup is set, and seal by the sucker sealing ring.

And vacuum-sealed cavity is divided into I vacuum chamber and II vacuum chamber by the torus partitioning sealing strip, and gastight joint is divided into first gastight joint and second gastight joint, respectively by stretching into I, II vacuum chamber outward.

And the subregion sealing strip is an annular setting, and making I vacuum chamber and II vacuum chamber is external and internal compositions, and perhaps the subregion sealing strip is the bar shaped setting, and making I vacuum chamber and II vacuum chamber is parallel construction.

And the magnetic force piece is a magnet steel, and embeds in the disk body.

And disk body is provided with the auxiliary briquetting of movable magnetic force.

And geometrical clamp is the spiral press plate mechanism.

And disk body is circle or quadrangle, and the shape of trying to get to the heart of a matter and card adapt.

The utility model has the advantages that, method of clamping such as magnetic, vacuum suction or spiral pressing plate can be provided, and can make up use, can compatible various sheet type workpieces, and also simple in structure, low cost of manufacture, easy to use.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

Embodiment one provides a kind of tetragonal scratch diskette, shown in Fig. 1 ~ 2, comprises disk body 1 and tries to get to the heart of a matter 2; Wherein, Disk body 1 and try to get to the heart of a matter vacuum-sealed cavity 3 is set between 2, disk body 1 is provided with gastight joint 4 by stretching into vacuum-sealed cavity 3 outward, and disk body 1 surface evenly is covered with the suction hole 5 that is communicated with vacuum-sealed cavity 3; Disk body 1 is provided with magnetic force piece 6; As shown in Figure 4, disk body 1 surface is provided with geometrical clamp 7.

Gastight joint 4 is to be threaded with disk body 1.

As shown in Figure 3, inhale 5 upper ends, hole vacuum cup 51 is set, and by 52 sealings of sucker sealing ring.

Vacuum-sealed cavity 3 is divided into I vacuum chamber 31 and II vacuum chamber 32 by subregion sealing strip 8, and gastight joint 4 is divided into first gastight joint 41 and second gastight joint 42, respectively by stretching into I vacuum chamber 31, II vacuum chamber 32 outward.

Subregion sealing strip 8 is annular settings, and making I vacuum chamber 31 and II vacuum chamber 32 is external and internal compositionses, and perhaps subregion sealing strip 8 is bar shaped settings, and making I vacuum chamber 31 and II vacuum chamber 32 is parallel constructions.

Magnetic force piece 6 is magnet steel, and embeds in the disk body 1.

Disk body 1 is provided with the auxiliary briquetting 9 of movable magnetic force.

Geometrical clamp 7 is the pressing plates with threaded rod, and the screwed hole that is provided with disk body 1 constitutes the spiral press plate mechanism.

Embodiment two be disk body 1 for circular scratch diskette, as shown in Figure 5, try to get to the heart of a matter 2 shape and disk body 1 adapt, other structures are identical with embodiment one.

Vacuum suction: through at gastight joint 4 external vavuum pumps, can make vacuum-sealed cavity 3 produce negative pressure, disk body 1 equally distributed suction hole 5 reaches the purpose of vacuum suction workpiece 10 to the bottom surface of negative pressure stepless action in workpiece 10.And, if workpiece 10 is less, then only need first gastight joint 41 is connected with vavuum pump, under the isolation of subregion sealing strip 8, have only generation negative pressure in the I vacuum chamber 31, assurance negative pressure intensity also reduces the power consumption of vavuum pump; If workpiece 10 is bigger, then first gastight joint 41 is connected with vavuum pump with second gastight joint 42 simultaneously, make I vacuum chamber 31 and II vacuum chamber 32 produce negative pressure simultaneously, absorption workpiece 10.Further, inhaling the vacuum cup 51 of 5 upper ends, hole setting, strengthen adsorption effect by 52 sealings of sucker sealing ring.

Magnetic force absorption: if workpiece 10 is magnetic materials, it is positioned over 1 surface last time of disk body, and the magneticaction that can receive powerful magnet steel is adsorbed in disk body 1, reaches the purpose of absorption.On workpiece, place simultaneously the auxiliary briquetting 9 of magnetic force, the magnetic force of the auxiliary briquetting 9 of magnetic force and powerful magnet steel and disk body 1 also adds that the gravity of self exerts pressure to workpiece 10, has further strengthened the stability of workpiece 10 on scratch diskette.

The spiral pressing plate is fixed: workpiece 10 is positioned on disk body 1 surface, the spiral press plate mechanism is pushed down the edge of workpiece 10 and stepped up, can reach fixing purpose.

Above-mentioned three kinds of suction types can be used according to conditions such as the actual material of workpiece 10, sizes, make the very big compatible scope that the utlity model has.
