Abstract

The invention relates to the timber and woodworking industry and can be used as a cutting mechanism for machine tools for transverse sawing of timber. The purpose of the invention is to simplify the design. The mechanism contains a circular saw 1, an electric motor 11, pulleys 12, 13, 14 of a V-belt drive, a worm gear reducer 9. On the hollow shaft 8 in the supports 3 there are coaxially mounted pulleys 12, 13, 14 of a V-belt gear, kinematically connected by a transmission roller 15. In addition The saw 1 with the saw shaft 2 is kinematically connected with the hydraulic motor 19 of the feed mechanism with the possibility of their portable rotational movement on the bracket 6 fixed to the shaft 8. The hydraulic station 17 of the main motor 11 is switched on in series. The movement from the electric motor 11 through the pulleys 12, 13, wedge gears 23, 24, the transmission roller 15 communicates with the saw shaft 2 to the saw shaft 1. Then, the workpiece is placed in the machining position and the electromagnetic valve 18 is turned on. The oil from the hydraulic station 17 enters the hydraulic engine 19, moving from through the coupling 22, shaft 20, the worm gear of the gearbox 9 is transmitted to the hollow shaft 8 and the bracket 6 mounted on it with the saw shaft 2 and the saw 1, which perform a portable rotary motion. 1 il.

The invention relates to the timber and woodworking industry and can be used as a cutting mechanism for machine tools for transverse sawing of timber.

The purpose of the invention is to simplify the design.

The drawing shows the structure of the cutting mechanism.

The cutting machine of the circular saw contains a saw 1, a saw shaft 2, made in the form of a wedge pulley with a 3-roll bearing and an axis 4, eccentrically fixed in a buckle 5 mounted on a bracket 6 with a counterweight 7, a hollow shaft 8, a worm gear 9, clamping flange 10 and drives for main movement and feed movement.

The main drive includes an electric motor 11, pulleys 12-14, mounted coaxially in the bearings of the shaft 8 of the gearbox 9. The pulleys 12 and 13 are kinematically connected by a transmission roller 15. The mechanism includes a sensor 16 for setting the saw shaft 2 to a saw 1.

The feed motion drive includes a hydraulic station 17, an electromagnetic hydraulic distributor 18, a hydraulic motor 19 is kinematically connected with the shaft 20 of the worm gear 21 of the gearbox 9, the coupling 22, and the sensor 16 of the position of the saw shaft 2 with the saw 1. The pulleys are interconnected by kinematic gears 23 and 24.

The mechanism works as follows. The hydrostation 17 of the electric motor 11 of the main movement mechanism is switched on in series, the movement from which through the pulleys 14, 12

and 13, wedge gears 23 and 24, the transmission roller 15 communicates with the saw shaft 2 to the saw shaft 2. The workpiece is then placed in the machining position and the solenoid valve 18 is turned on. The oil from the hydraulic station 17 enters the hydraulic motor 19, the movement of which is through the clutch 22 The shaft 20, the worm gear of the gearbox 9, is transmitted to the shaft 8 and the bracket 6 mounted thereon with the saw shaft 2 and the saw 1, which perform a portable rotary motion. For this case, it is the feed movement, during which the length of the workpiece is cut. The initial position of the saw 1 - lower, when moving to the upper position, cutting occurs. When the lower position is reached again, the movement by the bracket 6 from the position sensor 16 is automatically switched off, which can be used as

Zov limit switch. To perform the next cut, it is again necessary to turn on the electromagnetic, from the hydraulic distributor 18. The lower position of the saw 1 is fixed by the self-braking effect of the worm gear 21. The wedge transmission belts of the saw shaft 2 are not pressed, by turning the swivel shaft 5 with the eccentric axis of the pulley eccentrically fixed in it wedge transmission motor 11.
