Description

[Detailed Description of the Invention] The present invention relates to a product protection device during product movement.

A conventional example will be explained with reference to FIG. A vise 4 that supports the material to be cut is fixed to the base 1, and the base 1
The rotary table 2 is fitted into the rotary table 2.
In a table-top cutting machine, a hinge 5 is fixed to the hinge 5, a motor part 8 having a saw blade 11 is swingably attached to the hinge 5, and the cutting handle 9 is lowered to process the material. The cutting edge plate 3 is installed so that the cutting position and the cutting position with the saw blade 11 can be easily set. The cutting edge plate 3 is fixed to the center of the rotary table 2 (the lowered position of the saw blade). As mentioned above, the cutting edge plate 3 clearly indicates the cutting position of the material to be cut. Lower the saw handle 9 and make a cut to the lowest position of the saw blade 1 to make a groove in the cutting edge plate 3 equal to the width of the cutting edge. Further, in order to facilitate movement during movement, the saw blade 11 is structured so that the motor part 8 and the base 1 can be hooked together by a chain 21 or the like near the lowest position.

When the motor part 8 and the base 1 are hooked and moved by the chain 21, the swinging of the motor part 8 is not completely prevented, so it moves slightly, and the cutting edge of the saw blade 11 and the cutting edge plate 3 touch each other. It may come into contact with the cutting edge plate 3.
It had the disadvantage of damaging the

The purpose of the present invention is to eliminate the above-mentioned drawbacks of the prior art and to prevent damage to the cutting edge plate during product movement.

In the present invention, the positional relationship between the locking piece, the hinge, and the motor part is devised in order to install the locking piece so that the motor part can be reliably fixed at the lower limit position.

An embodiment of the present invention will be explained with reference to FIGS. 1 to 5.

A vice 4 that supports a material to be cut 22 is fixed to a base 1, a rotary table 2 is rotatably fitted to the base 1, and a hinge 5 is attached to the lower part of the rotary table 2.
is fixed. A handle 6 is provided protruding from the front end of the hinge 5. The motor portion 8 is swingably supported by the hinge shaft 7 on the hinge 5. A cutting handle 9 is installed on an extension of the motor portion 8. A saw blade shaft 10 is installed at one end of the motor portion 8, and the saw blade shaft 1
A saw blade 11 is fixed to 0. A stopper 15 for setting the lowest limit position protrudes from the lower part of the motor portion 8, and a set bolt 16 is attached to the hinge 5.
are screwed together. A spring 14, which is a compression coil spring, and a set pin 12 are movably fitted into the hinge 5, and a pin 13 is crimped onto the set pin 12. The motor portion 8 is provided with a set hole 22 into which the set pin 12 is pressed and fitted by the spring 14. The set hole 22 is provided at a fixed position slightly above the lowest position of the motor section 8.

In the above configuration, the cutting handle 9 is lowered to the position where the stopper 15 at the bottom of the motor part 8 and the set bolt 16 screwed into the hinge 5 come into contact (lowest limit position), and the saw blade 11 is used to cut the cutting edge plate. Delete 3. When moving, as shown in Figures 4 and 5,
By fitting the set pin 12 into the set hole 22 of the motor section 8 above the lowest position of the saw blade 11, the swing of the motor section 8 is suppressed;
Since the saw blade 11 and the cutting edge plate 3 can be prevented from coming into contact with each other, damage to the cutting edge plate 3 can be prevented. The spring 14 is a restraining member that prevents the set pin 12 from easily coming off during movement.

As shown in FIGS. 5 and 7, the rubber ring 19 is fitted into the groove of the sliding portion of the set pin 17, and the grip 18 connected to the set pin 17 is manually fitted into the set hole of the motor section 8. A similar effect can be obtained. The rubber ring 19 is attached to the set pin 1.
This is a restraining member for preventing 7 from easily detaching.

Further, by making the set hole 22 a screw hole, a tapered hole, etc., it is possible to suppress backlash of the motor part, and furthermore, the suppression of the motor part can be made more reliable.

According to the present invention, the swinging of the motor part above the lowest position of the saw blade can be suppressed by the locking device, so that contact between the saw blade and the saw blade when transporting the table cutter is prevented. Since this can be prevented, damage to the cutting edge plate can be prevented.
