Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an angle setting mechanism for a rotary table in a cutting machine that performs angle cutting using a rotary table.

Conventionally, in cutting machines that use a rotary table to cut angles, the rotary table can be rotated to cut any angle (0
45°, 30°, 45°, etc.), rotate the handle shaft 11 as shown in Figure 4.
Release the fixation of the rotary table 1, raise the lever 5, rotate the rotary table 1 by holding the handle shaft 11, lower the lever 5 near an arbitrary angle, and insert the lever 5 into the pin hole 3. When pin 9 is fitted, handle shaft 1
The handle shaft 1 is rotated and pressed against the base 2 to fix the rotary table 1.
There is a drawback that the grip position must be changed when rotating the lever 1, raising and lowering the lever 5, and rotating the handle shaft 11.

The purpose of the present invention is to eliminate the above-mentioned drawbacks of the prior art and to improve the operability when rotating the rotary table and setting the angle in order to perform angle cutting.

In order to improve the operability when setting the angle of the rotary table, the present invention improves the relationship between the handle shaft, grip, lever, and stopper pin so that the angle setting pin can be attached and removed using the rotary table rotation grip without changing the gripping hand position. It was devised.

Embodiments of the present invention will be described below with reference to the drawings.
The rotary table 1 is rotatably fitted to the base 2. The holder 4 is fixed to the rotary table 1. A lever 5 is swingably held in the holder 4 by a fulcrum pin 7. Spring 8 is held by fulcrum pin 7. The pin 10 passes through the pin hole of the holder 4 and is held on the lever 5 by the pin 9 so as to fit into the angle setting pin hole 3 of the base 2. The handle shaft 11 is screwed into the holder 4. The grip 6 is slidably held by a pin 12 corresponding to an elongated hole 13 of a handle shaft 11. The spring 14 is inscribed in the grip 6.

Next, the operation will be explained. When setting the angle of the rotary table 1, rotate the grip 6 to release the fixation between the rotary table 1 and the base 2, move the grip 6 forward to lower the lever 5, lower the stopper pin 10, and release the angle stopper. let Next, rotate the rotary table 1 by horizontally moving the grip 6, move the grip 6 backward around an arbitrary angle, and insert the pin 9 provided in the lever 5 into the pin hole 3.
Once they are fitted, the grip 6 is rotated and pressed against the base 2 to fix the rotary table.

According to the present invention, since the angle stopper pin can be raised and lowered by reciprocating the grip, the rotation angle can be set without changing the grip position, improving operability.

Claims (1)

[Scope of utility model registration request] a holder provided at the bottom of the rotary table fitted to the base; a lever having a stopper pin that is swingably supported by the holder via a support member; and a lever provided on the base corresponding to the tip of the stopper pin. A cutting machine having a rotary table angle setting mechanism consisting of a concave portion into which a stopper pin fits, and a handle shaft which is screwed into the tip of the holder and fixes the rotary table via a base. An elongated hole is provided in the direction, and a grip that is movable along the elongated hole via a pin and has a protrusion on the front end is attached to the outer diameter portion of the handle shaft. and an elastic body inscribed in the grip surface, and by pressing the grip in the axial direction of the handle shaft, the protrusion of the grip pushes down the lever and releases the stopper pin from fitting into the base recess. Rotary table angle setting mechanism.
