Abstract

The invention relates to woodworking machines and is intended to process the bent-glued sides of furniture for a seat. The purpose of the invention is to simplify the design of the machine. The machine includes a bed 1, tables 2, installed in at least two rows of two-end horizontal drilling units 3 with a drive of spindle rotation and oscillation. All units have the possibility of horizontal movement along the guides 11, vertical movement along the guides 12, and turning in a vertical plane. The base device is made in the form of vertically movable slats with stops, which are mounted on the tables by means of brackets 14 that are adjustable along the length of the tables. The slats are equipped with nozzles 19 for chip removal. The clamping device is a pneumatic clamp 17 movably mounted on the rods 18. The H-shaped blank is laid on the clamping strips and stops of one of the tables 2 and clamped by pneumatic clamps 17. When the table is pushed onto the tool, a hole is drilled or a slot is drilled. In the meantime, the workpiece is similarly laid and clamped on another table, which slides onto the tool when the first table moves to its original position. The machine is simple in design and has wide technological capabilities. 3 il.

moving along the guides 11, vertical moving along the guides 12 and turning in the vertical plane. The base device is made in the form of vertically movable slats with stops, which are mounted on the table by means of brackets 14 that are adjustable along the length of the tables 14. The slats are provided with nozzles 19 for chip removal. The clamping device is a pneumatic clamp 17, which is mounted on the rods 18 under the slide.

The invention relates to woodworking machines, namely, machines for processing bent-glued sidewalls of furniture for a seat.

The purpose of the invention is to simplify the design of the machine.

Figure 1 is a machine, side view; in fig. 2 shows a section A-A in FIG. figure 3 - view B in figure 2.

The machine includes a bed 1, tables 2, installed in at least two rows of two-end three-spindle horizontal drilling and grooving units 3 with a drive of 4 spindle rotations and a drive of 5 spindle oscillations. The rotation of the spindle and each unit is transmitted by means of a belt drive, the drive belt 6 of which is made poly V-ribbed and mounted on the drive 7 and bypass 8 gakivas. The belt by means of the spring loaded rollers 9 rolls up to the pulleys of 10 spindles and interacts with them along a path parallel to the movement of the oscillator 5 drive carriage. The oscillation of the carriages is performed using the crank from the engine through a gearbox (not shown). All units 3 have the possibility of horizontal movement along the guides 11, vertical movement along the guides 12 and rotation relative to the vertical plane of the bed guides 11 by 25 in both directions, which ensures 77538

The H-shaped billet is placed on the base strips and stops of one of the tables 2 and clamped by pneumatic clamp 17. When the table is pushed onto the tool, a hole is drilled or a slot is drilled. In the meantime, the workpiece is similarly laid and clamped on another table, which slides onto the tool when the first table moves to its original position. The machine is simple in design and has broad technological capabilities, 3 Il.

The possibility of processing a wide range of blanks for chairs and armchairs. For drilling the holes, the oscillation drive is turned off and the carriages of the aggregates 3 are fixed in the zero position by latches (not shown).

Drive tables 2 made in the form

pneumatic cylinders 12, the management of which provides a consistent supply of tables to the drilling units.

On each table 2 are installed

5 based and clamping devices. The basing device consists of brackets 14 (Fig. 3), having the ability to move along the table. On the brackets mounted brackets based

Q strips 15 with stops 15, which are installed in accordance with the configuration of the workpiece. The clamping device consists of pneumatic clamps 17 (FIG. 2) mounted on rods 18. Pneumatic clamps have the possibility of adjusting vertical movement of rods 18. All the clamping rods 15 are equipped with nozzles 19 for chip removal and

dust.

The operation of the machine is carried out as follows.

The brackets 14, the clamping strips 15 and the stops 16 of the clamping device are aligned with the product pattern, in particular the sidewalls of the chair. The rods 18 with pneumatic grips 17 of the clamping device are also aligned with the clamping elements.

The blank 20 (in FIG. 3 is shown by a dash-dotted line) is laid on the base strips 15 and the stops I6 of one of the tables. As soon as the workpiece is laid, it is automatically pressed by the pneumatic clamps 17 and the table begins to move onto the tool. Drilling or sampling of the required number of holes or grooves (by the number of tools installed) occurs. In the meantime, the other billet is laid on another table and clamped. As soon as the first table reaches its extreme position, it automatically returns to its original position, and the second table starts moving to the tool. When the first table reaches its initial position, the workpiece is released and the operator removes the machined part and places a new workpiece. When the second table reaches the extreme position, it returns to its original position, and the first table starts moving in the direction of the tool. The cycle is repeated.
