SU73581A1 - Sharpening machine for circular, chain and transverse saw teeth - Google Patents

Description

Machines for automatic sharpening of teeth of circular, chain and transverse saws, comprising: a swivel head with a grinding wheel, a device that is suitable for periodically raising and lowering the grinding wheel with a limiter, a clamping device for circular, chain and transverse saws are known.

A distinctive feature of the proposed machine is that it is made on one hollow metal rack with a rocker on which an electric motor is placed on one side, and on the other a rotatable head with a grinding wheel, and the rocker arm can rotate in a horizontal and vertical plane. To fix the depth of sharpening of the saw teeth and their fuzzing, a movable stop was used.

FIG. 1 and 2 shows the proposed machine.

A cylindrical column 3 and a cylindrical column 17 are mounted on the base / machine, in the upper part of which a stop screw is screwed in, fixed by a lock nut. On the post 3 there is mounted a swivel head 2 with a rocker arm 5 on which are placed on one side

an electric motor, and on the other a rotatable head 9 with a grinding wheel 12 A rotatable head 9 is attached to the yoke 5 by means of a boring bar 7 and nuts with a handle b. Their faces of the tool to be sharpened.

The rotary head 9 has a vertical hole through which the axis of the 8 frame of the grinding wheel passes, secured with a bolt 14. On the horizontal axis of the frame of the grinding cam, the grinding wheel 12 is attached on one side and the wheel 22 on the other to transmit the movement to the grinding wheel. Movement from the electric motor to the grinding wheel is transmitted by a belt drive 23 through pulleys 15, 10, and 22. A safety casing 13 is installed to enclose the grinding wheel 13. Boring 21 is attached to the base / machine by means of a yoke, bolt and nut 19.

Sharpened tool-disco, wa saw is mounted on the mandrel 20 and fastened with a nut. At the top of the bushing bar 21 installs 58S

with support-support 18 for the blade of the sharpened saw. The movement of the saw blade and the grinding wheel when manually cutting the cutting edges of the teeth of the saw blade.

To sharpen the chainsaws, it is necessary to replace the boring bar 21 with an emphasis 18 on the boring bar with an asterisk, on which the chain links are located. The chain is manually moved.

For sharpening cross-section and cross-cutting saws, a movable metal table is attached to the grinding wheel frame plate. Sharpening the edges of the cutting teeth at a certain angle is accomplished by raising and lowering the table relative to the center of the spindle axis of the grinding wheel.

For fixing the depth of sharpening of the sinuses of the saw teeth and their fugovki

applied movable B riat-ynop 16 in the upper part of column 17, which serves as a limiter of the movement of the rocker arm 5 in the vertical plane.
