Description

The invention relates to the woodworking industry and can be used for the manufacture of wooden wagon racks.

The aim of the invention is to increase productivity by reducing the time for fixing the blanks.

FIG. 1 shows a machine for processing the ends of wooden wagon racks, side view; in fig. 2 is the same, top view in FIG. 3 is a view A of FIG. one; in fig. 4 - view B on fig.Z; in fig. five -. u.zey; I in FIG. 3, enlarged; FIG. 6, section BB, FIG. one; in fig. 7 shows a lever with a cutting tool and rollers, side view, in FIG. 8 - the same, top view.

The machine for treating the ends of the carriage racks contains a frame 1, a centering mechanism with clamping jaws 2, a workpiece fixing unit 3, a cutting mechanism with cutting tools 4, a copier 5 and an actuator 6. The workpiece fixing unit 3 consists of a pedal 7, a vertical bar 8 , pivotally connected with one end to the pedal 7, and the other to the lower shoulders of 9 clamping jaws 2. Upper shoulders. 10 clamping jaws 2 have a serrated notch on their inner sides 11.

The frame is fixed on the frame to the guide 12, inside of which the movable carriage 13 of the cutting mechanism is assembled, consisting of two shoulders 14, on one shoulder of which cutting tools 4 are fixed, and on the other rollers 15, kinematically associated with copiers 5.

The support plate 16 is fixed for the workpiece 17. The drive includes an electric motor 18, a screw 19, a nut 20, a brake 21 and limit switches 22 and 23.

The machine works as follows.

The blank 17 is placed between the clamping jaws 2 of the centering mechanism, pushed inside the box-shaped guide 12 to the support bar 16, and the pedal 7 is depressed. The pedal 7 moves the vertical pull 8 down, which simultaneously rotates the jaws 2 in the vertical plane. In this case, the upper shoulders 10 sponges center and clamp the workpiece 17.

The drive 6 is turned on. The motor 18, turning the screw 19, moves the carriage 13 in the guide 12. The rollers 15 roll over the copiers 5 and turn the levers 14. The cutting tools 4 cut on four sides into the workpiece 17 and cut off part of the wood.

At the end of the working stroke, the carriage 13 interacts with the limit switch 22, which gives a signal for reversing the electric motor 18. After this, the carriage 13 moves in the opposite direction, reaches and interacts with the limit switch 23, which terminates the signal for stopping the electric motor. 18 and brake actuation 21.

During the movement of the carriage, in the direction of the limit switch 23, the pedal 7 is released, which, being spring-loaded, moves up the rod 8 and extends the upper shoulders 10 of the jaws 2, freeing the workpiece 17.

The preform is removed from the machine and the cycle is repeated.
