Abstract

PURPOSE:To improve positioning accuracies at mounting and demounting times by providing a cross groove at plural places on the back face of a mounting board for setting a work, and fastening this cross groove to a pallet by a special nut. CONSTITUTION:A cross shaped projection 8 is provided on the back face four places of a mounting board 7, and engaged with the cross groove 5 of the pallet 4 for electrode installed on a machine. A screw 6 provided at the cross groove 5 center of the pallet 4 is then inserted and threaded into the center of a cross shaped projection 8, and fastened with a special stepped nut 9 having a female screw being inserted into the mounting hole of the mounting board 7. Therefore, the mounting board 7 is positioned correctly with the fitting of the cross groove 5 and cross projection 8 into the pallet 4. Also the special nut 9 eliminates its heading onto the mounting board 7 surface and the danger due to the interference by a cutter, etc., can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] This invention relates to a mounting board that is used when relatively machining pressure is applied during machining such as a milling machine, and requires repeatable accuracy by being mounted and removed.

[Summary of the idea]

This idea is applied to the mounting board where the workpiece is mounted during machining, etc., and the pressure is 1.
This prevents scratches.

[Conventional technology]

Conventionally, as shown in FIG. 1, a method has been known in which a mounting plate 1 is mounted using two positioning pins 2 and a presser claw 3 from above.

[Problem to be invented or solved]

When machining, it is not completed in one go, but requires several removals or rinsing operations, which has the disadvantage of poor repeat positioning accuracy.

Another drawback was that the mounting plate could move due to the cutting force applied during machining.

Therefore, in order to solve the drawbacks of the conventional method, this invention aims to easily obtain parallel and perpendicular accuracy without requiring any number of installations and removals.

[Means to solve the problem]

In order to solve the above problem, the second idea is to
Positioning is done by providing a cross/Pi5 to regulate parallelism and perpendicularity, and a special stepped nut 9 is tightened from above so that it also comes to the mounting board, to prevent slipping due to pressure during processing.

[Effect]

This structure allows for easy positioning, and is sufficiently rigid to withstand pressure during processing.

〔Example〕

Examples of this invention will be described below with reference to the drawings.

Figure 2 shows the electrode processing pallet already installed in the machine. In this invention, as shown in Fig. 3, the pallet is used to tighten the mounting board from above, thereby ensuring compatibility.

FIG. 3 shows the mounting board 7 of the second invention, and the upper left side is a view seen from the back side. Reference numeral 8 denotes a cross-shaped convex portion, which fits into the cross groove 5 of the electrode processing pallet 4 and can be used for positioning in the X and Y directions. Numeral 9 is a special stepped nut having a female thread in the center that is threadedly connected to thread 6, and is fitted into a nut mounting hole 10, with its upper surface lower than the top surface of mounting board 7.

1] is a hole for Neshi 6. Reference numeral 12 denotes a mounting hole (not shown) for mounting a jig board on which a workpiece is placed. Reference numeral 13 denotes positioning pins of the jig board, and usually a pair are provided on both sides of the mounting hole 12. With this structure, the four XY cross protrusions can be fitted and fixed into the cross grooves, which not only provides repeatable positional accuracy but also high rigidity, eliminating the worry of displacement due to pressure generated during processing. Additionally, since it is tightened with a nut, there is no protrusion on the mounting board, eliminating the risk of interference with cutting tools, etc.
