Abstract

The utility model discloses an auxiliary centering device which includes at least one L-type centering plate. The vertical part and the horizontal part of the centering plate are perpendicular each other. At least one end plane of the centering plate is perpendicular to the adjacent internal side wall. The groove holes are opened in the centering plate and equipped with the magnetic block used for adsorbing workpieces waiting for measurement. By setting the magnetic block in the L-type centering plate, the workpieces measured are well contacted with the centering plate and will not loose during the measuring process, which improves the measuring precision; a round hole with a gap is set at the right-angle of the L-type centering plate, which makes both side walls at the right-angle of the square or rectangle workpieces completely joints with two internal walls of L-type centering plate and improves the measuring precision. The work efficiency can be improved by setting two centering plates.

As illustrated in fig. 1 and 2: device in the auxiliary branch of the utility model magnetic, comprise plate 1 in two L types branches, the plate vertical portion is vertical mutually with horizontal part in the branch, plate 1 has at least an end face vertical with adjacent madial wall in the branch, have slotted eye in the branch on the plate, be provided with the magnetic patch 2 that is used to adsorb workpiece to be measured 4 in the slotted eye.Preferably, have slotted eye on the upper surface of plate vertical portion in the branch, be provided with magnetic patch 21 in the slotted eye, also have slotted eye on the plate 1 horizontal part upper surface in the described branch, be provided with magnetic patch 22 in the slotted eye, magnetic patch 2 is preferably magnet, and magnet is embedded in slotted eye inside, certainly, described slotted eye can be made as through hole, also can be blind hole, considers the absorption affinity of practical operation convenience and magnet, be preferably logical slotted eye, above-mentioned magnet also can be arranged on plate 1 in the branch in, on the lateral wall, grooved bore on sidewall is located at magnet in the slotted eye, when slotted eye was opened at madial wall, the outer surface that is positioned at the magnet of slotted eye was positioned at same plane with the surface of this madial wall at least or is lower than the surface of this madial wall.

Further, described divide near the L type in magnetic patch 2 two sides and the corresponding L type branch of plate two madial walls the distance between plate two madial walls be respectively 0.5～1.5 millimeter, be preferably 1.0 millimeters.

The length of described magnetic patch 21 be in the whole branch plate vertical portion length 1/2 to 2/3, preferred, be 2/3, the length of described magnetic patch 22 be in the whole branch plate level minister degree 1/2 to 2/3, be preferably 2/3.

Plate fully contacts in measured workpiece and the branch in order to improve, and improves certainty of measurement, and place, plate right angle was provided with circular hole 3 during described L type divided, and plate two madial wall junctions have breach in this circular hole 3 and the branch.

The work engineering:

As shown in Figure 1, workpiece 4 clampings are after line cuts on the backing plate 3, further work is the operation of looking for workpiece centre, size according to workpiece 4, select the long limit or the minor face of plate 1 in the magnetic branch are placed on the side surface of workpiece that needs measurement, plate 1 relied on magnetic force to be fitted in a jiao of workpiece during magnetic divided, keep each face all to put in place, the corner, right angle of workpiece 4 is not (as being the corner, right angle, the extension intersection that guarantees the both sides outer wall of workpiece will meet at right angles) follow the corner, right angle of plate in the magnetic branch to overlap, at first to be provided with line when the wire cutting machine device cut silk 5 contacts divide in during plate, machine just halts, reduce the error of manual operation like this, can improve certainty of measurement, then can cut the position that 5 end face that bump plate in the magnetic branch of the left side is determined device end face in the branch with line, described end face is vertical with adjacent madial wall, same operation, cut the position that 5 end face that bump plate in the magnetic branch that another is the right determines to install in the branch end face with line again, described end face is vertical with adjacent madial wall, utilize on the electronic ruler on the online again cutting mill during the electronic tool chi asks, can draw the mid point on the width of the workpiece direction, plate 1 is positioned over the another side of workpiece X or Y direction in then a magnetic being divided, long limit or minor face are placed on the identical side of workpiece equally, utilize line cutting silk to bump in the branch plate again and determine two positions, mid point on the Workpiece length direction can be measured like this, at this moment, we have measured two positions, the mid point of these two positions promptly is the center of workpiece, plate also can be selected one for use in the above-mentioned branch, by moving 3 positions, can measure the center.

The right-angle structure (shown in Figure 2) that this magnetic divides middle auxiliary device that the L shaped shape of similar letter is arranged, material is the mould steel high-abrasive material, hardness is more than the HRC50 degree, and be to be embedded in the slotted eye, madial wall will have certain fineness, guarantees the precision of measurement, and the two side is vertical mutually, short face is vertical with medial surface, and tolerance is within 0.002 millimeter.
