Description

The proposed utility model relates to the woodworking industry and can be used for drilling holes with a given drilling angle for screw loops on parts of a door block with surfacing using paired drilling groups.

Known drilling and additive machines that carry out drilling in the vertical and horizontal planes, the machines are similar in performing technological operations and have almost the same disadvantages, in particular:

1. Machine boring and additive ALFA 21T, 27T, 35T (VITAP) - Italy. Drilling holes in the sheets and edges of panel parts of cabinet furniture, table size, mm: for model 21T - 864 * 500; for model 27T - 1056 * 500; for model 35T - 1454 * 590 (Machine tools and tools for furniture production, catalog 2007, MDM-Techno, p. 69).

2. Drilling and additive machine MVM 21 P (OMKOTECH) Belgorod. Designed for high-precision drilling of through and blind holes in the ends and planes of furniture panels. The inclination of the drilling unit is pneumatic, 0-90 degrees, the distance between the spindles - 32 mm (Electronic resource. Access mode: http://www.equipnet.ru/equip/equip_5857.html);

For wood processing there are boring-grooving machines.

1. LBM-200 boring and grooving machine - Austria-Bulgaria, used for drilling holes / grooves in solid parts, wood particle boards and fiber boards. Table rotation angle, degrees ± 45; wide spindle stroke range (transverse - 200; longitudinal - 240 mm). Number of spindles, pcs - 1 (Woodworking equipment of domestic and imported production, “Kami-Stankoagregat”, p. 75).

2. Drilling and grooving machine SVPG - 2A. Designed for sampling grooves and drilling holes simultaneously in two wood products in serial production. It has a table rotation angle of ± 25 ° (Woodworking equipment of domestic and foreign production, “Kami-Stankoagregat”, p. 75).

3. Drilling and grooving machine MDK 4120. Simultaneous drilling of holes, milling and selection of grooves for hinges, larvae and lock case in the door leaf and box. Doors can be made of both solid wood and MDF. The maximum length of the machined parts is 2200 mm; the width of the workpieces 600 - 1000 mm. Number of spindles - 7 pcs. (Woodworking equipment, issue No. 5, “Kami-Stankoagregat”, p. 53).

The following machines can serve as analogues for the development of a boring-additive machine:

1) SVPG-2A drilling and grooving machine with a bed and the possibility of tilting the table for drilling holes with horizontal and vertical movement of the spindle with a drill diameter of 1 to 30 mm. Despite the possibility of turning the table, drilling one pair of holes is carried out in at least two passes with the rearrangement of the position of the spindle or part with limited dimensions of the machine table 500 * 400 mm;

2) MDK 4120 slot-grooving machine with a bed with optimal working table dimensions and a set of spindles that allow drilling holes with the ability to adjust the distance between them, but only for one pair, while there is no possibility of turning the table by a given angle while drilling several pairs holes.

The disadvantages of almost all machines are:

1) the center-to-center distance between the spindles is 32 mm, while under the screw loops the center-to-center distance is 25 mm.

2) machines are not intended for drilling parts of door blocks with surfacing;

3) there is no possibility of turning the drilling groups at an angle of 11 °;

4) the small size of the surface of the desktop, not providing the ability to drill parts up to 2.5 m

5) the absence of paired drilled on the spindle heads.

EFFECT: reduced labor intensity and accelerated drilling process due to simultaneous automatic operation of several (from two to four) paired spindle heads.

The technical result is achieved in that the drilling machine for drilling holes for screw loops in the details of the door block with a weld, including a frame, characterized in that the frame has rails mounted on which from two to four paired spindle heads are movable on rails for drilling workpieces in the horizontal plane for box parts and at an angle of 11 ° for blade parts, while on the bed there are vertical clamps for securing the workpiece a.

The heads on rails mounted on the bed move in a horizontal plane, providing drilling at a length of up to 2.5 m and in vertical, with the positioning of the spindles at an angle of 11 °. A diagram of the device is shown in FIG. one.

The diagram shows: a tubular frame bed (1) with rails (2), on which two to four spindle heads (3) are mounted with paired drills (4). The pneumatic drive of the machine (5) provides the simultaneous supply of all pairs of spindle heads. On the bed for mounting parts (6) there are clamps (7). Turning the machine on and off is carried out by the start button.

The work of the machine is as follows:

- when drilling the details of the door block box with surfacing:

1. The part is laid on the table and fixed with clamps;

2. set the drilling angle to 0 degrees (horizontal plane);

3. move the spindle heads on the rails for installation at the desired distance (according to the assembly drawings, determining the location for drilling);

4. choose the optimal cutting parameters: drill type and feed rate depending on the type of material (wood or plate materials);

5. Start up with simultaneous supply of all spindle heads with paired drills to the part with a travel distance of up to 50 mm.

6. - if it is necessary to change parts from the bars of the box to the bars of the door leaf, a lining bar is installed for drilling in a horizontal plane (angle 11 °). Further actions are repeated in the same sequence, with the exception of paragraph 2 on setting the angle.

Technical result:

- it is possible to drill holes with a pitch between spindle axes of 25 mm (instead of traditional ones - 32 mm) with an accuracy of 11-12 degrees;

- it is possible to process parts with a length of up to 2.5 m with a quick change of angle depending on the set technological tasks from 0 to 11 °;

- a quick readjustment of the machine is possible and verified, which contributes to the addition of holes, both on the bars of the door leaf and on the box.
