Description

Clamping device for grinding metal sheet

The technical field is as follows:

the utility model relates to a grinding tool, specifically speaking are exactly a clamping device who grinds foil.

Background art:

At present, clamping devices for grinding metal sheets are rare, and the metal sheets are difficult to hold in the grinding process, the ground surfaces are difficult to ensure on the same plane, and the grinding process of holding the metal sheets can cause damage to fingers and the like. The Dun family love et al's Utility model ' a clamping device for polishing a surface of a metal sheet ' (patent publication No. 202649018U) solves the problems of difficulty in holding and finger damage during polishing. However, when the device is used for grinding a thin sample, the sample is difficult to clamp, the surface of the sample after clamping is not flat, and the corresponding clamping device is worn due to the sample being too thin in the grinding process. The utility model 'metallographic specimen clamping device' (patent publication No. 108857892A) of Xuhong et al at Jilin university is only suitable for polishing block specimens with regular shapes, and can not clamp extremely thin sheet specimens.

On the basis of the technical scheme, the following further technical scheme can be provided:

The top end of the upright post is provided with a cantilever which is vertically distributed with the upright post, and the cantilever and the upright post are integrated into a whole to form a structure.

The bottom plate is provided with grooves distributed corresponding to the cutting edges of the guillotine.

the hand-held cutting knife is also provided with a hand-held part, and the hand-held part and the hand-held cutting knife are of an integrated structure.

Utility model advantage:

The utility model discloses simple structure, foil centre gripping convenience, easy operation, be applicable to polishing of extremely thin foil sample.

Description of the drawings:

Fig. 1 is a structural diagram of the present invention.

the specific implementation mode is as follows:

As shown in fig. 1, a holding device for grinding a metal sheet includes a base plate 1, and a post 1a welded to an upper surface of the base plate 1. The upright column 1a is a hexagonal prism, the central axis of the hexagonal prism is perpendicular to the upper surface of the base plate 1, and the central axis is close to one end of the base plate 1. The midline of the hexagonal prism is positioned at one side of the center point of the upper surface of the bottom plate 1.

The top end of the upright post 1a is provided with a cantilever 1c which horizontally extends along the width direction of the bottom plate, and the cantilever 1c and the upright post 1a are vertically distributed. A projection 1d extending downward is provided at the end of the projecting end of the cantilever 1 c.

the cantilever 1c, the bulge 1d and the upright post 1a are of an integrated structure. The upper surfaces of the cantilever, the upright post and the bottom plate just form a groove-shaped structure, and the convex part plays a role in limiting. So that the operator can grip the upright more easily and is not easy to get out of hand.

The end part of the bottom plate 1 at the other side of the center point of the upper surface of the bottom plate 1 is provided with a group of first threaded holes 1b, the first threaded holes 1b are countersunk holes, and the group of first threaded holes 1b are three and distributed along the width direction of the bottom plate 1.

Set up a splint 2 below bottom plate 1, splint 2 length is the same with bottom plate 1's width, is equipped with a set of second screw hole 2b corresponding with first screw hole 1b along its length direction on splint 2 every first, two screw holes in wear to be equipped with corresponding complex first screw 3, through first screw 3 with splint 2 fixed connection on the lower surface of bottom plate 1 other end tip.

One end of the thickness end surface at one side of the length direction of the clamping plate 2 is provided with a third threaded hole 2a which is horizontally distributed. A guillotine 4 is arranged along the length of the clamping plate 2 and has the same length as the clamping plate 2. The end part of one end of the guillotine 4 is an arc end, the end part of the end is provided with a unthreaded hole 4b distributed corresponding to the third threaded hole 2a, a second screw 5 is inserted into the unthreaded hole 4b and the third threaded hole 2a, and the guillotine 4 is connected with the clamping plate 2 through the second screw 5. And a handheld part 4a extends from the end part of the other end of the hand hay cutter 4 along the length direction of the hand hay cutter, and the handheld part 4a and the hand hay cutter 4 are of an integrated structure.

On the 1 lower surface of bottom plate between stand 1a and first screw hole 1b, be equipped with the recess 1d that open notch is decurrent along the width direction of bottom plate 1, recess 1d for leading to the groove structure to correspond the distribution with hand hay cutter 4, make the hand hay cutter cutting edge can imbed in the recess 1d when rotating hand hay cutter 4.

The working process is as follows:

First insert second screw 5 in unthreaded hole 4b and third screw hole 2a, rotate the hand hay cutter and make its cutting edge downward, then screw second screw 5 for hand hay cutter 4 is in the same place with splint 2 fixed connection, and the nut of second screw 5 compresses tightly the hand hay cutter, makes the hand hay cutter can not rotate.

Then lay the foil 6 of treating polishing on bottom plate 1 lower surface, then place splint 2 at foil 6 one end tip, splint 2 fixed connection is on bottom plate 1 lower surface to the rethread first screw 3 to clip foil 6.

At this moment, the staff can drive the metal sheet 6 clamped on the lower surface of the bottom plate 1 to be tightly attached to the edge of the abrasive paper grinding table by holding the upright post 1a by hands, and the bottom plate is moved back and forth along the width direction of the bottom plate, so that the metal sheet is ground.

the convex part 1d can effectively limit the hand of a worker, and the hand-off condition when the worker moves the bottom plate back and forth is avoided

after polishing, the second screw 5 is loosened to enable the guillotine 4 to rotate, then a worker holds the holding part 4a of the guillotine 4 by hand, the guillotine 4 is rotated to enable the cutting edge of the guillotine to be inserted into the groove 1d, the metal sheet 6 is cut, and the polished metal sheet is separated from the unpolished metal sheet (clamped between the bottom plate 1 and the clamping plate 2).
