Abstract

The invention relates to milling machines for processing open profile sockets in wood parts and can be used in the woodworking industry. The purpose of the invention is to increase productivity and simplify the design. The device comprises a frame 1, bases 4.5 for an eccentric mechanism 6 and its drive 7. The eccentric mechanism is made with a horizontal axis of rotation of the eccentric and contains horizontal plates 8 and a vertical plate 9, which is mounted on horizontal plates by means of vertical guides 12. On a vertical plate set table 18 with the top 19 and side 20 clamps. The cutting units are support platforms 21 with studs 23, electric motors 22 and spindle heads 24. There is a magazine 25 and a mechanism for issuing blanks from it to the table 18. The blank given from the magazine is oriented oriented on the table 18 and clamped. The rotating slider of the eccentric mechanism 6, connected to the vertical plate 9, causes the movement of the latter vertically and horizontal plates 8 horizontally. As a result, table 18 with a fixed workpiece receives a complex movement along a circular path, sufficient to mill the open profile slot. 2 Il.

the workpiece is oriented on the table 18 and clamped. Rotating slider eccentric mechanism 6,

 connected to a vertical plate 9, causes the movement of the latter vertically and horizontal plates 8 horizontally. As a result, table 18 with a fixed workpiece gets

10 complex movement along a circular path, sufficient for milling a nest of an open profile, 2 sludge.

The invention relates to milling machines for processing open profile sockets in wood parts, for example in tare inserts, and can be used in woodworking industry.

The purpose of the invention is to simplify the design and increase the productivity of labor.

FIG. 1 shows the device, a general view; fig 2 is an eccentric mechanism.

The device comprises a frame 1, which is a frame of a welded structure, on which guides 2, supports for spindle screws 3 and bases 4 and 5 for eccentric MexaifflSM 6 and its drive 7 are installed. The eccentric mechanism contains horizontal 8 and vertical 9 plates and support column. 10 beds on which horizontal guides 11 are made for horizontal plates 8; Vertical plate 9 is mounted on horizontal plates 8 by means of vertical guides 12,

The eccentric; new mechanism is made up of a composite and consists of a housing 13 rigidly connected with a horizontal drive shaft 14 and a slide 15 connected at one end to a vertical plate 9 and the other to a housing by means of a radial groove 16 and a driving screw 17,

A table 18 is mounted on a vertical plate, on which are placed the top 19 and side 20 clamps. The cutting unit consists of state-support calipers 21, on which electric motors 22 and racks 23 with spindle heads 24, driven in rotation from electric motors through a V-belt transmission, are installed. The mechanism for issuing blanks from the magazine 25 to the table is a chain device 26 with tilting stop 27, which is located under the store,.

The device works as follows.

The blanks are manually laid on a narrow edge in the shop 25, which is adjusted to the dimensions of the processed blanks. By the chain device 26, the workpiece is fed to table 18, where it stops oriented at the rear end in the machining zone. After fixing by the upper clamps 19, the drive of the eccentric mechanism 6 which is preset to the processing parameters is automatically activated,

Rotating slider 15 causes horizontal movement in guides 1 G of support column 10 horizontal 8 and vertical 9 associated with them, and the last, except for

In addition, it receives a vertical movement in the guides 12 on the horizontal

As a result, the workpiece, fixed on the table 18, gets a complex movement along a circular path (bottom to top). It fits. To the rotating cutters (according to the number of sockets) and undergoes processing. At the same time, all machinators are milled with a step determined by the drawing on this product according to the presetting of the milling supports. At the end of one circle, the eccentric mechanism, and with it the table, stops in the initial (lower) position, the upper clamp releases the workpiece and

most of all gives the command to turn on the drive of the chain device, which stops 27 from the store and seizes the next billet and delivers the table to the treatment area. The processed part is pushed out of the subsequent processing zone and enters the receiving part of the autonomous sorting device. The process then repeats.

The use of the proposed device makes it possible to increase labor productivity in milling operations of curved surfaces of an open profile (nests) due to simultaneous processing of all nests on the workpiece for one revolution of the table by two or more times as compared with the prototype. In addition, the design of the proposed device is simple.
