Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention is a multi-axis punching device in which a plurality of lifting mechanisms are installed side by side on a support table installed on a machine base, and a punch is connected to each lifting mechanism. Regarding

(Prior Art) Conventionally, as this type of multi-axis punching device, those shown in FIGS. 4 and 5 are known.

This punching device has a structure in which a plurality of mounting holes 2 are opened in a support 1, a lifting mechanism 3 is inserted into each mounting hole 2, and a punch 5 is connected to a lifting rod 31 of the lifting mechanism 3. Has been done.

In the apparatus, the lower end portion 33 of the lifting mechanism 3 is formed in a small diameter and is inserted into the mounting hole 2, and the support base 1 of the lower end portion 33 is formed.
A nut member 10 is screwed into a portion projecting to the lower surface side, and the nut member 10 is rotated by a spanner or the like to move the lifting mechanism 3 up and down, whereby the lower end of each punch 5 can be punched. And the upper limit position that cannot be drilled.

(Problems to be Solved by the Invention) According to the above-described conventional punching device, a relatively large work space S is provided between the elevating mechanisms 3 for rotating the nut member 10.
Therefore, the punching pitch P by each punch 3 is required.
Could not be made smaller than a certain size.

The present invention has been made in view of the conventional circumstances as described above, and an object of the present invention is to make the above-mentioned working space as small as possible and bring the respective lifting mechanisms into close contact with each other.

(Means for Solving the Problems) In order to achieve the above object, the multi-axis punching device of the present invention has a plurality of lifting mechanisms arranged side by side on a support table installed on a machine stand and punches for each lifting mechanism. In the multi-axis punching device, the lower end of each elevating mechanism is inserted into the support and the flange is provided at the portion protruding toward the lower surface of the support,
A lower piece of a U-shaped positioning tool that engages the upper surface of the support base with the upper surface of the support base is brought into contact with the flange portion, and the lower side is flanged by an adjusting bolt screwed into the support base. It is characterized in that the lower end of each punch is individually adjusted to a lower limit position where punching is possible and an upper limit position where punching is impossible.

(Operation) According to the above configuration, by moving the adjusting bolt up and down with a tool such as a screwdriver, the lower piece of the positioning piece presses the collar portion to move the elevating mechanism up and down, and the lower end of each punch is punched. Adjust individually to the lowest possible position and the highest non-piercing position.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

In FIGS. 1 and 2, reference numeral 1 denotes a support base, and the support base 1 is installed on a machine base (not shown) having a plurality of receiving holes at appropriate intervals. A plurality of mounting holes 2 are opened in the support base 1 at a desired pitch P (for example, about 6 mm) so as to face the receiving holes, and an elevating mechanism 3 is arranged in each mounting hole 2. It

The elevating mechanism 3 is composed of a cylinder 30 inserted into the mounting hole 2 and fixed to the mounting hole 2 via a positioning tool 4. The punch 5 is connected to the lifting rod 31 of the cylinder 30.

The cylinder 30 is provided with a locking flange 32 on the outer periphery of the middle part thereof and has a lower end 33 formed in a small diameter, and the lower end 3d is inserted into the mounting hole 2 and locked on the support 1. A portion of the lower end portion 33 projecting to the lower surface side of the support base 1 is formed in a small diameter shape, and a flange portion 33b is provided at a lower end of the small diameter portion 33a.

The positioning tool 4 is formed in a U-shape so that the support base 1 is sandwiched, and the tip of the upper side 41 thereof is engaged with the upper surface of the support base 1 to support the support base 1.
The lower side 42 is hooked on the side end and extends to the position just below the mounting hole 2 so that the lower surface of the tip 42a abuts on the flange 33b. The lower edge 42
Is urged downward by the adjusting bolt 6.

The adjusting bolt 6 is provided with a screw hole 7 formed by penetrating the support base 1.
Further, the lower end of the positioning tool is screwed so as to come into contact with the lower side 42 of the positioning tool.

According to the above configuration, the lower end of each punch 5 is individually adjusted to the lower limit position where punching is possible and the upper limit position where punching is not possible by moving the adjusting bolt 6 up and down using a tool such as a screwdriver.

When the punch 5 is at the lower limit position, when the cylinder 30 operates from that state, the punch 5 moves to the work W.
If the punch 5 is at the upper limit position by inserting the punch 5 into the receiving hole of the machine base and the punch 5 is at the upper limit position, the lower end of the punch 5 does not reach the work W even if the cylinder 30 operates. I can't. Thereby, a plurality of (for example, 30) punches 5 are prepared, and only any one of the punches 5 can be punched, so that the punching of the work W can be performed without a troublesome work such as moving the punches 5. You can change the pattern.

(Effects of the Invention) Since the present invention is configured as described above, it is possible to adjust the lower end of each punch to the lower limit position where punching is possible and the upper limit position where punching is not possible using a tool such as a screwdriver. This makes it possible to reduce the working space as compared with the case of adjusting work using a spanner or the like as in the conventional device.

Therefore, the respective elevating mechanisms can be closely arranged side by side, and the punching pitch between the punches can be further reduced.
