Description

Multiple vertical machine tools are known with spindles located on a turntable and cutting tools fixedly mounted on tool holders on a machine table.

However, such machines are not sufficiently productive as they do not provide for continuous turning of rotating workpieces with simultaneous removal of waste and automatic removal of finished products.

The described machine does not have these disadvantages.

This is achieved by the fact that the machine is equipped with onboard suction pumps of pneumatic waste transport, and at the last position is the mohm of automatic removal of finished products.

FIG. 1 shows a kinematic diagram of a machine drive: iia of FIG. 2 is a diagram of a carousel; in fig. 3 - removal mechanism, top view; in fig. 4 shows a section along A-A in FIG. 3

The electric motor / V-belt 2 transmits rotation to the main drive shaft 3, and the latter transmits rotation with a greater number of revolutions to spindle heads 6 through the driving gear 4 and the driven gears 5, the number of which is equal to the number of PTDheads.

On the carousel table 7 (Fig. 2) of the machine are installed fifteen spindle heads, and on a fixed frame there are sixteen tool holders 8 with cutters 9 fixed in them.

Wood workpiece 10, fixed between the spindle // of the head and clamping center 12, rotates the machine at a low speed with a successive turning of the cutting tool, each of which is given a profile corresponding to a certain chip removal operation.

Since fifteen incisors fixed to the tool holders are in operation, the sixteenth free tool holder adapts No. 146022-2lnna for fastening the mechanism for removal of finished products using a cylindrical rack 13 (Fig. 3).

The removal mechanism is a roller 15 loosely seated on the sleeve 14, covered by a two-part segment 16, the second part 17 of which is connected by means of a spring-loaded joint 18 with the first part. The segment is secured by means of a spring-loaded hinge connection 19 to two cheeks 20 rigidly connected to the sleeve 14.

When the table is rotated, the product released from the spindle head after processing by all the cutters, in this case a chess piece, is pushed by a carved recess into the gap between the roller and the segment, rejecting it by a small amount. The finished product, moving between the segment and the roller, rotates the latter, after which the product, having reached the notch 21 in the segment, falls into the capacity of the finished products.

The adjustment of the height of installation of the roller with a segment is carried out with the help of a finger 22, freely movable in the sleeve 14.

The machine is turned on and stopped by a mechanism in the form of a shaft 23 (FIG. 1), driven by a V-belt 24 from shaft 3, and gears 25 and 26.

Chip removal is carried out by means of flanges mounted around the machine's circumference in the form of sockets connected to a common pneumatic conveying network.

A prototype of the proposed machine was tested at the Khaitura factory of food products. Tests have shown that worker productivity has increased sevenfold, working conditions have improved, and product quality has improved.

Subject invention

A multi-spindle vertical machine with spindles located on a rotary carousel table and cutters mounted stationary on the tool holders on the machine table, characterized in that to ensure the continuous processing of rotating wooden workpieces while removing waste and automatic removal of finished parts on the machine side suction pneumatic transport of waste, and in the last position - the mechanism of automatic removal of finished products.
