SU1219349A1 - Appliance for turning internal hollow in wooden articles on lathe - Google Patents

Description

The invention relates to the woodworking industry, in particular, to equipment for turning internal heels in wood products of considerable size.

The purpose of the invention is the expansion of technological capabilities.

FIG. 1 shows a diagram of the device, top view; figure 2 - section aa in figure 1; on fig.Z - section bb in figure 1.

The device works as follows.

A workpiece is placed in the headstock 1, fixed with a clamping chuck, and the outside of the workpiece is machined to a predetermined profile in the usual way. In the preform, until the end of the intended cavity, a hole is drilled to install the boring device 4 with one end into it. A quill is removed from the body of the tailstock and, in its place, the device contains a set-up locator installed on the machine and fixes the front headstock 1 with the clamping chuck and the tailstock 2 with the quill. In the tailstock quill 2, a handpiece 3 is installed, consisting of a guide 4 on which movable platform 5 is mounted with the cutter 6 installed and platform 7 with a probe holder 8, a chart recorder 9 and a pen 10.

On the bed lathe secured

4 borers, and the other end places it in the prepared hole of the workpiece. The platform 5 and the control and copying unit 11 are installed as close as possible to the workpiece being processed. Then the cutter 6 and the holder-probe 8 of the recorder 9 are adjusted to the synchronous operation of the template 12. The template 12 is moved to the area of work with the control copying unit 11, consisting of 20 bodies, probe 8. In this position, the moving template 12 and tape tape The platform 13 and the platform 13 and the control copier with a ribbing tape 14. The node 11 is fixed on the guide, choose a convenient position for the handle 23 of the subPlatform 5 has a base 15 and a new cutter and secure it with a lock 24. when installed the turning gear drive and the manual cutter 6. The platform 7 has a base of 25 and 23 that influence rotation 17 and the rotary part 18, on which the mouth part 16 of the mobile platform 5 s

cutter.m 6, with the holder-probe 8 of the recorder copies onto the tape 14 the stroke of the cutter 6 inside the cavity of the workpiece, thus controlling the entire developed surface of the cavity of the workpiece.

When a certain work experience is achieved, the mobile platform 7 can be released from the lock in the direction of j. 4 and

A recorder holder 8 is mounted 9. The bases 15 and 17 of platforms 5 and 7 are interconnected by a thrust rod 19 with a handle 20 and a clamp 21, and the rotary parts 16 and 18 of the platforms are connected by a locking rod 22 with a handle 23 and a clamp 24. Basis 15 and 17 of platforms 5 and 7 are installed on guideline 4 with the possibility of reciprocating.

control the movement of the cutter 6 by joint movements of the handles 23 and 20.

The device works as follows.

A workpiece is placed in the headstock 1, fixed with a clamping chuck, and the outside of the workpiece is machined to a predetermined profile in the usual way. In the preform, until the end of the intended cavity, a hole is drilled to install the boring device 4 with one end into it. A quill is extracted from the body of the tailstock and, in its place, with one contour by the movement of the cutter 6, the combined movements of the handles 23 and 20.
