Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below by referring to the drawings are exemplary only for explaining the present invention, and should not be construed as limiting the present invention.

The following disclosure provides many different embodiments or examples for implementing different aspects of the invention.

Example 1

Referring to fig. 1 to 4, in an embodiment of the present invention, a tool for edging a planar target includes an electromagnetic chuck 1, two fixtures 2 and two stoppers 5, both the fixtures 2 and the stoppers 5 can be magnetically adsorbed on the electromagnetic chuck 1, the electromagnetic chuck 1 is provided with a recessed portion 11 for placing a planar target, two guide grooves 12 communicated with the recessed portion 11, and the two guide grooves 12 are symmetrically arranged on both sides of the recessed portion 11 in the length direction and extend in a direction perpendicular to the length direction of the recessed portion 11;

the clamp 2 comprises a bottom plate 21 and a vertical plate 22, wherein the bottom plate 21 is connected with the guide groove 12 in a sliding mode, and the vertical plate 22 is fixed at one end, close to the concave part 11, of the bottom plate 21 and forms an L shape with the bottom plate 21;

during the use, remove two anchor clamps 2 in opposite directions, make two riser 22 centre gripping the plane target in the depressed part 11, it makes it support tight plane target to remove dog 5, at this moment restart electromagnetic chuck 1 adsorbs anchor clamps 2 and dog 5, the plane target just can be fixed, the length direction of the side of at this moment plane target is exactly the length direction of depressed part 11, and electromagnetic chuck 1 generally is fixed state, only need set up the walking orbit of the grinding piece of grinding machine, just can repeatedly carry out the edging to a plurality of plane targets, the time of counterpointing at every turn has been saved, the efficiency of edging has been improved.

Besides the function of positioning the planar target, the concave part 11 can also provide good support for the planar target, and the planar target can be leveled better only by finely machining the bottom surface of the concave part 11 to ensure that the bottom surface has good flatness.

Generally, the width of the concave portion 11 is larger than the thickness of the planar target, so as to facilitate the placement of the planar target; the thickness of the flat target is generally not greater than 15mm, the width of the recess 11 is not too large, which is about 30mm, and the width of the grinding part of the grinding machine can cover the width of the recess 11, so that the grinding machine can grind the edge as long as the flat target is fixed in the recess 11.

As a concrete embodiment of the present embodiment, the bottom plate 21, the vertical plate 22, and the stopper 5 are all made of S45 steel, but other materials that can be attracted by the electromagnetic chuck 1 are also applicable.
