Description

The invention relates to the woodworking industry.

Shpalopravochnye machines are known, having a frame with mounted lia her with a possibility of movement by means of a guide carriage, a cutting mechanism with a working body in the form of a milling cutter, a clamping device and a feeder.

In known machines, the working body has the ability to move relative to the processed sleepers rotationally and reciprocally in a vertical plane. Schnal, mounted on a trolley, makes movement only in a horizontal plane. Due to the fact that the dimple radius of the curvature of the sides is not constant, and the cutter has a certain profile, a poor-quality sleeper mandrel is obtained, i.e., the bark, bast, wormhole, etc. remains, and these defects are removed manually.

In order to improve the quality of processing the sleeper blanks and ensure the rotation of the sleeper blanks when it is oriented relative to the working body, the milling cutter of the proposed machine is mounted on a carriage made with the possibility of reciprocating motion using a stepless speed controller and connected by means of a rack and pinion with a running roller, and turning clamping device with clamping centers mounted on a common rigid frame with the possibility of movement in a horizontal plane, Rich the pushing drive, the workpiece rotation and infeed shnalnoy cutter adapted booster. FIG. 1 shows the finishing scheme of the described machine; in fig. 2 - machine carriage. The stack consists of a feeder /, carriage 2,

moving along the guides 3 by means of a troso-block system 4 from the hydraulic drive 5, a cutting mechanism 6 with a working member in the form of a milling cutter 7 and a rotating clamping device 8.

The milling cutter 7, driven by an electric motor 9, is mounted on the rod 10, a rail 11 is mounted on the cohort and meshes with the wheel 12 fixed in turn on the frame of the carriage 2. Through the wheel 12 passes the running roller 13 of square or hexagonal section, along which the wheel 12 can move freely. The running roller / 3 is connected by means of a pinion gear 14 to a hydraulic booster 15, the stem of which

not installed relative to the machine frame.

As a hydraulic actuator I, a speedless speed regulator-system is used, consisting of a variable-producer pump, a reciprocating motion of carriage 2, and the possibility of reversing it when passing in any place.

The rotary clamping device 8 is a rigid frame 1b mounted in guides 17 for movement in a horizontal plane and having centers mounted along the ends of clamping 18 and turning 19. The frame 16 is connected to the mainboard amplifier 20, the brush of which is fixed fixed relative to the frame of the flock.

The rotary center 19 through a rack and pinion 21 is connected to the hydraulic booster 22, the brush of which is fixed relative to the frame of the device 8.

The hydraulic boosters 20 and 22 are hydraulic follow-on drives of manual control and have control levers 23, to which are attached the control wires 24, which are led out to the control panel 25.

The machine works as follows. The operator from the control panel acts on the control of the hydraulic booster 20 and brings the rotary clamping device 8 to the feeder /. The sleeper located on the feeder / is clamped at the centers 18 and 19. Then the device 8 with a sialo is fed back to the mill 7. After evaluating the unoorned side of the shnaly relative to the milling cutter 7, the operator through the steering control 24 of the hydraulic booster 22 through a rack and pinion 21 and the pivot center 19 rotates the tie in the centers 18 VI 19 and the desired position. After that, the rotary-clamping device 8 can be additionally fed to the cutter 7 from it. Through the hydraulic booster, by means of the rail 8 and the wheel 12, the milling cutter is lowered and the piercing of the required depth into the sleeper.

At the same time, the carriage 2 is driven along the sleeper.

In this way, the sleeper mandrel is produced. In the case of a poor-quality mandrel sleepers with a single pass (for example, not the entire surface is processed, left) traces of bast, bark) using hydraulic boosters 20, 22 and a rotary center 19, the rotational movement of the sleeper and its orientation to the required position are reported, and the methods described above are selected remaining vices.

At the end of the debarking, center 18 frees the sleeper and it is moved to the side, for example, by a conveyor. Then the cycle is repeated.

Subject invention
