Exclusion refers to woodworking machines, in particular, universal machines for drilling holes in mjiTOBbix for details of furniture and other wood products in small-medium and medium-sized production.

The purpose of the invention is to provide the technological flexibility of the machine without complicating the design with a simultaneous reduction in set-up time.

FIG. 1 shows the proposed machine, rear view; in fig. 2 shows section A-A in FIG. one; in fig. 3 - schemes of refueling the drive belt; in fig. 4 is a diagram of the base on the table of the machine; in fig. 5 - placement of spindles in the crossheads; Fig. 6 illustrates an example of complete machining of a part from three sides into four installations.

The universal horizontal multi-spindle drilling and filler machine (Fig. 1) consists of a bed 1, a holder of 2 spindles and a table 3 (Fig. 2). The bed is made in the form of a box-like frame with guides 4 (behind) and 5 (above). On the rear guide 4, the holder of 2 spindles is hung, with the possibility of moving it up and down with the help of the bolt 6. The holder 2 (Fig. 1) is a yoke with a number of sockets 7 for interchangeable spindles 8, fitted with

depending on the location of the holes being drilled, the corresponding spindles 8 are inserted and fastened with screws 16. The belts 10 are threaded in one of the diagrams between both the pulleys 12, 20 and the rollers 21 and are tightened with a movable plate. By the side stops and the scales on them on the table 3, the workpiece 32 is set and processed. It is possible to reduce the setup time of the machine during the transition from one pattern of location of the drills 13 to another. 6 Il.

normalized in furniture industry in increments of t and with two drives 9 spindle rotations 10 flat belts 10. Replaceable spindles 8 (fig. 2) are made in the form of pins 11 with pulleys 12 and drills 13. For fixing the spindles each pins 11 have a key 14 the protrusion 15, and in the holder 2 opposite each of the sockets 7, the bolt 16 is screwed in. The tensioning mechanism of each actuator 9 consists of the plate 18 being moved along the guide 17 (Fig. 1) and the tension screw 19. On the plate 18, the actuator is mounted. motor with a pulley 20 and bending roller 21, Each belt 10 (Fig. 3) can be Drive from two to four spindles.

On the upper rail 5 (Fig. 2) of the bed 1, a table 3 is installed with a feed mechanism in the form of a pneumatic cylinder 22 and a depth control mechanism 23. The pneumatic cylinder stem 24 has a threaded end on which a nut with a steering wheel 25 is screwed. The nut allows the position of the piston 26 to be changed, i.e. stroke, and thus the depth of drilling.

The device for clamping parts is mounted above the table 3 on two L-shaped brackets 27. On the brackets, through the holders 28, the rod 29 is fixed, on which pneumatic cylinders 30 are hung with clamping points 31,

Pt 31 presses the workpiece 32 to the surface of the table 3.

The device for positioning the part contains a longitudinal 33 (Fig. 4) and lateral 34 (left) and 35 Right) stops. A longitudinal stop 33 is attached to the edge of the table 3, and the lateral stops 34 and 35 are fixedly movable along the grooves 36 of the table 3. Table 3 is provided marks 37 with step t, located opposite the axis of the sockets 7 (Fig. 1). The side abutments 34 and 35 are provided with scales 38 (FIG. 4), the reference points of which are offset from the base edge 39 of the abutment by a distance which is a multiple of the position of the nests on the traverse. For machining parts with intercenter spacing of the holes smaller than the diameter of the pulley 12 (Fig. 5), the machine is additionally equipped with a duplex nozzle 40 with gear transmission 41.

The machine is also equipped with a set of interchangeable spindles 8, and the drills 13 are previously pre-sized to the size H (Fig. 5) outside the machine.

The machine works as follows.

Before starting, the machine adjusts the depth of drilling.

live. The required set of interchangeable spindles 8 (Fig. 2) are inserted into the holder 2 of the spindles (Fig. 1) and fastened with bolts 16. Fill the belts according to one of the diagrams (Fig. 3) and tighten them with screws 19 (Fig. 1 ). The side stops 34 and 35 are placed, and the distance from the base edge of the workpiece 32 to the first hole to be drilled is 1 (provided that 1 is not more than 2xt in this particular case). The readout is carried out directly on a scale of 38. The rotation of the handwheel 25 (Fig. 2) sets the depth of drilling. The clamps 30 are positioned and include a pneumatic system and drive motors (not shown). On the table 3 set the item to be processed 32

on the stops 33, 34 and 35 (Fig. 4), include clamps 30 and the course of the table 3. The part is moved onto rotating

 drill bit 13 and drill holes. After returning the table 3, the clamp 30 releases the part 32, which is removed from the machine. Then the cycle repeats.

10 As can be seen from the foregoing, a multi-spindle machine with a set of interchangeable spindles and stops makes it possible to combine multi-tool and element-by-element processing (Fig. 6),

15 At the same time, due to the location of the beater rollers on the movable plates of the tension mechanisms, the setup time of the proposed machine is significantly reduced compared to the known one.
