Description

The invention relates to a coning machine but a tree and can be used in woodworking industry.

Known copy milling machine for wood with a carousel table, including the mechanisms of the clamp, made in the form of double-arm, milling head, a copier and drive.

The purpose of the invention is to increase labor productivity.

This is achieved by the fact that spring-loaded ejectors are fixed on the machine table, each pressing mechanism is made with a sleeve inside which a rod is installed. The upper end of the rod is connected by a lever arm, and at the lower end of the rod a roller is attached, which interacts with the copier while working.

FIG. 1 shows the proposed machine, plan; in fig. 2 and 3 - sections along A-A and BB on the fng. one; in fig. 4 - machine, side view.

Copy milling stack includes carousel table 1 with copiers 2, conventional mechanisms 3, ejectors 4, drive and milling head 5.

The carousel table is mounted on the shaft 6, which is mounted on the frame 8 by means of two arms 7. A cylindrical pin 9 is attached to the lower end of the shaft 6, which is located in the catch with the link 10 attached to the gearbox shaft //. The gearbox // means of the V-belt transmission 12 is driven by the electric motor 13.

There are eight copiers 2 and eight mechanisms 3 on the non-rotation of the carousel table, pressing the next workpiece 14 to the table / during its processing. On copier

there are stops 15 against which the workpiece rests to take a fixed position on the carousel table. The clamping mechanism 3 consists of a two-armed lever 16 pivotally connected to a stand 17 rigidly fastened on the carousel table.

To the moral nlechu lever 16 attached nlanka with lining 18, and to the left shoulder-end of the spring 19, the other end of which is connected to the eyelet 20.

Next to the rolled 20, a sleeve 21 is attached to the carousel table, inside which rod 22 is mounted. Through the slot of the upper end of the rod 22 passes the left arm of the lever 16, and in the slot of the lower end of the rod a roller 23 is harnessed to the frame 5. Under the carousel table, a guide 5 is attached to the frame 5 copier 24.

passing through the sleeve 26, pressed into the through-hole of the carousel table. An ejector 27 is mounted on the upper end of the axis 25, and a lever 28 is seated on the lower end. The ejector 27 and the lever 28 are mounted on the shaft at a certain angle.

Spring 29 tends to turn axis 25 with levers 27 and 28 counterclockwise.

A frame 30 is attached to the frame 8, on which a ball bearing is mounted with a pin, and a shelf 31. On a shelf 31 there are four supports 32. In the holes of the supports there are bolts with nuts attached to the figure plate 33. Under the action of springs 34 the plate is pressed to carousel table.

The milling head 5 contains an electric motor 34. A milling cutter 35 is rigidly mounted on the electric motor shaft and a support ring 36 is loosely mounted. The electric motor 34 with a milling cutter 35 and the support ring 36 is enclosed in a casing 37, the side plate 38 of which is connected to the axis 39, in turn attached to frame 8.

A roller 40 is pivotally attached to the bottom of the plate 38, resting on the shelves 41 to prevent the milling head from tilting.

A bolt is attached to the top of the plate 38. The eye of the bolt is threaded through the end of the spring 42, and the other end is threaded into the eyelet 43 attached to the frame 8. Therefore, by means of the spring 42, the milling head is constantly attracted to the carousel and the support ring 36 always contacts the copier 2.

Copy milling machine works as follows.

The motor 13 through a V-belt transmission 12, the gear 11 of the gears 9 and 10 causes the rotation of the shaft 6 and the carousel mounted on it /.

The milling cutter 35 is driven by the electric motor 34.

The blank 14 is placed on the copier 2 so that it rests against the stops 15 and is pressed against the table with the help of springs 34 by the figured plate 33 in order to avoid falling out during the movement of the table.

When the carousel table, turning counterclockwise, approaches the workpiece with the milling head, the roller 23 finds on

the guide copier 24 rises, and at the same time the rod 22 rises along with the left arm of the lever 16. At the same time, the right arm of the lever is lowered and presses the workpiece to the table.

Under the action of the spring 42, the milling head is attracted to the table, and the support ring, rolling over the copier, brings the milling head closer or away from the table. In this way, depending on the shape of the copier, the milling cutter 35 cuts the wood layer from the workpiece, giving it the desired configuration.

After processing the workpiece, the carousel table is rotated at a certain angle,

the roller 23 is released from the guide cam 24, and under the action of the spring 19 the rod 22 with the roller 23 and the left shoulder of the lever 16 are lowered, and the right shoulder of the lever 16 rises and releases the finished part from the clamp.

Upon further rotation of the carousel table, the lever 28 of the device for ejection of finished parts, protruding beyond the frame attached to the frame into the ball bearing, rests against the free end and, turning,

slides on it until it passes. As the carousel table moves counterclockwise, the lever 28 rotates about a certain angle clockwise relative to it, causing the axis 25 to turn

spring 29 and ejector 27 are also clockwise. At the same time, the ejector 27 rests against the finished part with a free end and automatically pushes it out of the socket into the prepared container.

Spring 29 returns the levers 27 and 25 to their original position.

Subject invention

Copy milling machine for wood with a carousel table, including clamping mechanisms made in the form of double-arm levers, a milling head, a copier and a drive, characterized in that, in order to increase production, spring-loaded ejector pins are fixed on the machine table, each pressing mechanism is made with a sleeve in which the rod is installed, the upper end of the rod is connected with one lever arm, and at its lower end a roller is pivotally fixed, which interacts with the copier in the process.
