る。 The present invention will be described in detail below with reference to drawings showing an embodiment of a positioning screw of a square chisel attachment angle setting device in a square chisel machine.
The square chisel installation angle setting device 1 includes a spindle case 2
A square chisel 3 is rotatably held on the lower end 2a of the cylindrical shape by a locking bolt 5 through a sleeve 4, and is opposed to a circular cutout 4a formed on one side of the sleeve 4. A screwed member 6 as a set holder is arranged in the spindle case 2 so as to be rotatable and perpendicular to the axial direction of the sleeve 4, and the outer periphery of the screwed member 6 is cut out to form cutout surfaces 7 and 8, respectively. At the same time, set screws 9, 9, 10, 10 are screwed in so as to protrude from the respective notch surfaces 7, 8. It is configured to be screwed into screw holes 11, 11, 12, 12 retractably provided through the screwed member.

る。 In the above configuration, the elastic body 14 is attached to each threaded portion 16 of each set screw 9, 9, 10, 10...
As shown in FIG. 3, the two are engaged by biting, and the two are frictionally engaged by the elastic force of the elastic body 14.
Each set screw 9, 9, 10, 10 is prevented from rotating.

る。 As explained above, according to the set screw rotation prevention mechanism according to the present invention, the threaded portion 1 of the set screw 9...
Since the resilient body 14 is brought into pressure contact with the set screw 6 for frictional engagement, the resilient body 14 bites into the screw thread and rotates in the perpendicular direction and the axial direction with respect to the axial direction of the set screw 9. By the restoring force of the elastic body 14, that is, by the elastic body acting in two directions, it is possible to effectively prevent the setscrews 9 from turning, and the forced screwing of the setscrews 9. On the other hand, since the elastic body 14 is compressible and deformable, it is possible to adjust the screw movement for positioning the set screw while still preventing rotation. Since we use a material with high hardness such as rubber, threaded part 1
There is little wear due to pressure contact with 6, and it has excellent durability.Furthermore, multiple setscrews 9 can be prevented from rotating with a single elastic body 14, and the structure is simple, so it can be implemented at an extremely low cost. It has practical effects such as:
