Abstract

FIELD: woodworking industry. The purpose of the invention is the expansion of the technological capabilities of the machine. The machine includes a frame 1, a table 2 with a stop ring (CC) 3 having a tooth 9. UK 3 is installed on the bed and the table using an annular bearing 21, bearing 22, located in the profile groove 23 of the UK 3. UK 3 is mounted on a drive floor a shaft consisting of two parts - the upper 14 and the lower J5, having a J7 connector. The workpiece 25 on the conductor 7, by pressing the teeth 9 of the CC and the roller-roller chain of the conductor together and transmitting the rotation of the CC 3 from the shaft parts 14 and 15, is automatically rotated and machined by the milling tool 5. with the linear edges not required by the conductor 7 and the mechanism for moving it, the table 2 with the nodes installed therein is removed and the machine is converted into a simple milling machine with a lower spindle arrangement. 5 il. x- / i (L

The invention relates to milling machines for processing parts with curved contours and can be used in woodworking.

The purpose of the invention is the expansion of the technological capabilities of the machine.

Fig, 1 shows a diagram of the machine view in plan; FIG. 2 is a section A-A in FIG. 1; in fig. 3 - node I in FIG. 2; in fig. 4 - view B in FIG. 3; Fig, 5 - machine in converted form.

The machine for processing parts with curvilinear contours includes a frame 1 on which table 2 is installed with stop collet 3, spindle 4. with cutter 5, caliper 6, jig 7 with stub-roller chain 8 that engages teeth 9 ring 3, the jig 7 is pressed against the teeth of the m 9 using the slider 10, the finger P, the pressure roller 2 and the spring 13 o The stop ring 3 is mounted on top of the drive shaft (not shown) that spans 4 and is made of the upper 14 and the lower 15 parts connected by U-shaped protrusions 16, in complements connector 17 at the ends of bottom part 15 of the hollow shaft is mounted inside the frame 18 by Stars bearings 19 and sliding the housing 20o inner diameter of the hollow shaft over the cutter diameter. The upper part 14 is mounted on the frame by means of an annular bearing 215 bearings 22 mounted on its end surface and the profile groove 23, made in the stop ring 3,

Position 24 marked the groove in the table 2, and the position 25 - the workpiece.

The machine works as follows. The workpiece 25 is laid on the jig 7 and clamped with clamps (not shown). Include three-drive. The lower part 15 of the drive hollow shaft transmits movement through the protrusions 16 of the upper part 14 and the stop ring 3 with the teeth. The pedal pulls down the pressure roller 12 "After the in-roller chain 8 engages with the teeth of 9 retaining ring 3, the pedal is released and the spring 13 pressure roller 12 moves through the finger 11 s.

a slider 10 presses the jig 7 to the stop ring. The jig 7 with the workpiece 25 is automatically rotated during the whole process. At the end of processing, roller 12 is retracted, the conductor is returned to its original position and the part is removed. Next, the processing cycle is repeated.

To use the machine for other technological purposes, for example, for milling the straight edges, it is converted (Fig. 5). The finger 11 with the pressure roller 12 is unscrewed from the slide 10 and the table 2 is removed with the annular bearing support 21, the stop ring 3 and the upper part 14 of the hollow shaft. The lower part of the 15-hollow shaft does not interfere with the operation of the machine, as it is below the table surface.

As the incisors are developed in this area of the cutter 5, the spindle 6 is lowered somewhat.

The use of the invention allows to expand the technological capabilities of the machine, make rational use of cutters with carbide inserts, increase tool life.
