Abstract

Invention applies to the wood processing industry. The invention aims to increase the carpentry lathes reliability. Lathe consists of a base (1), product (3), template (2) with a controller (4), also a drive (7) and cutter (5) with a holder (6). The cutter (5) holder (6) has an option of turning and lengthwise motion. It is attached to an axis (8) and has a control lever (9) with a regulator (12) and controller (4). The cutter blade (18) is bent in a letter V shape. After the positioning by the regulator (12) cutter(5) level and timber cutting depth, the cutter holder (6) by taking the control lever (9)is being pulled lengthwise the axis (8) and the cutter is being pulled in the direction of the length of the rotating product (3) blank. For the next pulling the cutter (5) is being lowered by a regulator (12).

Description

The present invention relates to a wood lathe.

Known machines for forming wood shapes with a base, mounting and feeding devices, cutting tools and gear. Between the anchors, the devices are fitted with movable supports · having a disc shape. The discs will make cuts and have studs attached to their side surfaces. A support gutter is made on the support for the workpieces, and the feeder 10 is made in the form of a slider {former USSR 'aut.

witness No. 431991, 1974).

The disadvantage of such looms is their complexity.

Technically closer woodworking machine with base, template, tracker, actuator, and knife holder. The knife holder is mounted on a ·· worm gear allowing movement of the wheel. Earthworm and caliper drive are connected to the same axle (Former USSR Certificate No. 489634, 1975).

The disadvantage of such a device is its lack of reliability because, with an uneven workpiece surface, a knife will not be able to remove it reliably if it has an uneven removable layer.

The object of the present invention is to improve the reliability of the device.

The stated purpose is achieved by making the following changes to a known base workpiece processing machine consisting of a base, a product template with its follower, a drive and a knife with its holder: ·

The knife holder with rotation and longitudinal movement is mounted on the axle, has a control lever connected to the tracker adjuster, and the knife holder

BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a general view of the machine; 3 - Top view.

The machine consists of a base 1, a template 2 mounted thereon, corresponding to the shape of the product, and a knife holder 5 for contacting the knife 5 via the follower 4 via the follower 4. The holder 6 has a control lever 9, connected by a latch ΊΟ and an axial shaft 11 to the regulator 12 of the follower 4. The follower 4 is connected via a backing plate 13 to the regulator 12 and the holder 6 of the blade 5, the length of the portion of the follower 4 in the holder 6. The regulator 12 has a latch 10 with an upper level 14, a center support 15 and an end point 16. On the opposite side from the bracket 6 axis 8 a counterweight is fixedly connected to the bracket 6

17. Blade 5 of knife 5 is V-shaped and directed in the direction of tangent 3 of article.

Machine works like this: Product-3 workpiece attachment *

at the actuator 7 / The regulator 12 'is secured at the upper level 14. The actuator 7 is rotated, rotating the workpiece in the opposite direction of the blade 5. The control lever 9 pulls the holder 6 along axis 8, the follower 4 extends along the template, copying its surface, and the knife 5, lowered onto the workpiece 3, slides in a rotating ratchet, carving on its surface the indentations corresponding to the template 2 '. As the blade '5 passes through the entire length of the workpiece 3', the regulator 12 is fixed at the center support 15 of the latch 10, thus lowering the knife 5 and pressing against the workpiece 3. In this position of the knife, it is again interrupted along the workpiece 3 by copying the template 4 with the tracker 4. The recesses in the surface of the workpiece 3 are deepened, the knife 5 reaches a larger and still intact part of its surface. re-perfecting, now for. at the end point 16 and the knife 5 with the holder 6 is interrupted a third time by the surface of the workpiece of the rotating article '3, reaching its entire surface and deepening the recesses to the depth required by the article 3. The product '3 is then disconnected from the actuator 7 and another workpiece is inserted.

Compared to the prototype, the machine tools offered are more reliable. They provide better product quality because several times, sometimes by adjusting the chip thickness on the surface of the product being cut * - easier to prevent tearing. More reliable work and clogging - the knife does not rest on the thick layer that makes it possible

- Fractures of the knife. The non-stick adjustable layer provides more reliable working conditions for the rotary motor and the workpiece because of a more even load. The V-shaped blade blades uniformly on all sides, providing reliable protection against wood tearing and surface defects. By allowing recesses in the product, one side of the arc removes the main chip and the other compares the surface. It reliably ensures surface quality and reduces. grinding labor costs and expenses. A single knife can be used to turn the entire shape of the product.
