Description

[Detailed description of the invention] TECHNICAL FIELD The present invention relates to an improvement in a grating machine.

When joining two canals, at the ice phase end of one of them,
A groove is cut and a mortise is provided at the other end of the sluice, but the structure of a chiseling machine generally consists of a vertical chisel blade and a horizontal saw blade for adjusting the workpiece. and a lifting member that moves up and down via a column erected on the base;
The machine is equipped with a vice in which a slider moves in the cutting direction while clamping the workpiece I.

In the above configuration, when performing mortise and tenon processing on the workpiece, after clamping the workpiece with a part of the slider of the vise (specifically, 5, a pair of left and right clampers installed on the slider), The slider is moved to the position where the desired tenon length is obtained, but the movement of the slider has traditionally been done manually, and the movement of the elevating member is still difficult. Generally, this is done manually using a member operator. In addition, although automatic movement of the elevating member has recently been proposed, in any case, no one has yet been proposed that automates the movement of the slider and the elevating member.

The present invention has been made in consideration of the above points, and includes:

After that, the elevating part 4 descends to perform the predetermined cutting, and the elevating part 4 moves to the specified position.
When the lower limit position detection lever B of 44 comes into contact with the lower limit position detection switch of the pace 1, the elevating member 4 starts returning, and the upper limit position detection lever ■ of the elevating part phase 4 detects the upper limit position of the bridge 3. It contacts the switch 10 and returns to the initial state. 1. Even in the case of so-called long mortise machining, in which the length of the tenon required for the workpiece is long, in the illustrated embodiment, the calculation circuit counts the length that can be cut with one saw blade. 34 and a calculation circuit 35 that determines the number of reciprocations of the lifting part phase 4 based on the count value of the calculation circuit function, and the lifting member 4 automatically reciprocates according to the determined number of times, which improves work efficiency. Excellent continuous work is possible. For example, as shown in FIG. keyboard 30
Value entered from (required tenon length for workpiece material)
120g, one pulse from the detector 24 and the part, and the length of tenon that can be cut with one saw blade is 50. He cut the length of 50-2 times twice, 3. It is sufficient to cut the remaining 20 spots in the first cut.

When the chiseling process is completed, operate the clear switch shown between the symbols in Figure 2 to erase the keyboard addition values that have been stored in the memory, and then turn on the reversible motor 21 for moving the slider. If you reverse it, you will see that the center position detection member 4 attached to the slider 17 is attached to the base member holder! - The slider 17 comes into contact with the position detection switch 27 and stops at the initial cent position.

The present invention is as described above, and according to the present invention, the entire process from clamping the workpiece to a part of the slider of the vise to completing the chiseling process is automated.
It is possible to obtain an improved mortise machine that is excellent in terms of both work efficiency and labor saving.
