JPH06226700A - Trowel pressure regulating device for mark cutter - Google Patents

Abstract

PURPOSE:To make possible the adjustment of a balancer fitting position according to the cut material in use so as to obtain desired contact pressure by providing a balance lever disposed on the rotational center opposite side to a trowel lever and mounted with a movable and adjustable balancer. CONSTITUTION:In a mark cutter, a movable Y-shaft base 27 is mounted on a Y-shaft 11 orthogonal to an X-shaft, and cut material is fused by a trowel tip 31 at the tip of a trowel lever 28 mounted on the Y-shaft base 27, thus cutting out a mark of desired shape. The trowel tip 31 is driven into a pressure position below the surface position S of a baseplate by rotating the Z-shaft bush 26 of an eccentric cam by the driving of a Z-shaft motor and rotating the trowel lever 28 downward around a shaft 32. In this case, a balance lever 33 is mounted on a trowel fitting base 29, on the opposite side to the trowel body fitting position, and a balancer 34 is slidably fitted to the lever 33. The decrease quantity of the pressure applied to the trowel tip 31 can be adjusted by adjusting the distance of the balancer 34 from the shaft 32.

SUMMARY OF THE INVENTION In these conventional devices, in order to cut out, it is necessary that the contact pressure when the tip of the iron portion comes into contact with the molten metal surface is high to some extent so that a desired character or pattern can be easily formed. It is preferable because it can be cut out. However, when using a material with a mount as the material to be cut,
If the contact pressure is too high, cut marks will be extremely left on the mount. This cut mark has a raised shape, and there is a problem that the material to be cut is attached here and is unsightly when transferred. Due to the drop in pressure to solve this,
Although it has been attempted to finely adjust the maximum lower position of the tip to the upper side, a small change in the length causes a remarkable change in the pressing force due to the replacement of the tip, and stable cutting can be performed. Can not.

Therefore, as a result of various investigations by the inventor, an X-axis portion provided in one direction on the side of a molten cross section having a flat surface composed of a main body cover and a base plate, and the X-axis portion A Y-axis which is movably mounted on the X-axis in the Y-direction orthogonal to the section and which moves in parallel with the X-axis by a driving device, and a Y-axis which is movably mounted on the Y-axis and moves parallel to the Y-axis by the driving device A Y-axis base and a first position in which a tip is formed and a tip is attached rotatably with respect to a rotation center attached to the Y-axis base, and the tip of the tip is grounded at least in the melting section. And a balance lever that is controlled to a second position that is elevated from the melting surface, and a balance lever that is provided on the opposite side of the rotation center from the iron lever and that is equipped with a balancer that is adjustable in movement. The problem was solved by using a trowel pressure adjusting device for the cutter.

[0005]

The desired contact pressure is set by adjusting and setting the mounting position of the balancer according to the cut material used.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is an external view of a mark cutter. For details, refer to Japanese Patent Application No. 02-2661 filed by the applicant of the present application.
8 and the Japanese Patent Application No. Hei 2-8982, etc. Reference numeral 1 denotes a main body cover which covers the main body base. A base plate mounting recess is formed in the center of the main body cover, and the base plate 5 is mounted in the recess. Reference numeral 4 denotes an operation panel on which a cutting condition can be set.

An X is formed on the lower portion of the side surface in the longitudinal direction of the body cover 1.
The X axis is fixed on the main body base via the shaft support fixing plate and the X support. An X-axis bearing fixing plate is slidably fitted on the X-axis via an X-axis bearing portion. It can be driven by a dedicated motor.

In FIG. 2, a Y-axis side plate A9 is screwed to the X-axis bearing portion fixing plate, and the Y-axis side plate B10 faces the Y-axis side plate A9 to connect the Y-axis A11, the Y-axis B12 and the Z-axis 13. A guide roller A21 and a guide roller B22 are screwed to the Y-axis side plate B10 by sandwiching them so that the Y-axis portion can move on the base plate 5 along the X-axis so as to be slidable at right angles to the X-axis. Has become.

A Y-axis base 27 is slidably attached to the Y-axis A11 and the Y-axis B12, and is movable by the motor 14 via the belt 16 along the Y-axis. As shown in FIGS. 3 and 4, an iron lever shaft 32 is fixed to the Y-axis base 27, and an iron lever 28 is rotatably fitted on the iron lever shaft. A trowel mount 29 is fixed to the lever, and a trowel body 30 is attached to the trowel mount.

A Z-axis motor 24 (not shown) is fixed on the Y-axis base 27, and the Z-axis 13 whose rotation is transmitted to the Z-axis motor is made up of a Y-axis side plate A and a Y-axis side plate B. It is supported. A Z-axis bush 26 of an eccentric cam is fixed to the Z-axis 13, and one end of the iron lever 28 is in contact with the outer circumference of the Z-axis bush.

Therefore, the Z-axis motor 24 is driven to drive the Z-axis 1
When the minimum eccentric portion of the Z-axis bush 26 fixed to 3 contacts the iron lever 28, the iron lever 28 rotates downward about the iron lever shaft 32 as shown in FIG. The tip 31 of the iron is at a pressing position below the surface position S of the base plate 5, and the pressure of the iron load is applied.
The headstock 27 is driven in the X direction and the Y direction to perform the cutting work.

When the Z-axis motor 24 is driven so that the maximum eccentric part of the Z-axis bush 26 comes into contact with the iron lever 28, as shown in FIG.
As described above, the iron lever 28 rotates upward about the iron lever shaft 32, and the tip 31 of the tip of the iron main body 30 is in the open position above the surface position S of the base plate 5 to the next position. It is possible to move or shift to the initial state.

A balance lever 33 is attached and extends on the side of the iron holder 29 opposite to the iron body mounting position.
A balancer 34 is mounted on the balance lever so that the distance from the iron lever shaft can be adjusted.

Therefore, when the balancer 34 is not mounted, the pressure applied to the tip 31 is almost the weight of the lever main body 30, but the force applied to the tip 31 is adjusted by adjusting the amount and the mounting position of the balancer. The amount of pressure reduction can be adjusted and set.

FIG. 5 shows a second embodiment of pressure adjustment, in which the iron body mounting position side of the iron holder 129 is further extended, and the balance lever 133 is provided on the side opposite to the iron body 130.
And the balancer 134 is fitted on the balance lever so as to be movable and adjustable. Therefore, as in the first embodiment, by adjusting the amount and mounting position of the balancer 134, the amount by which the pressing force applied to the tip 131 is reduced can be adjusted and set.
