SU1371918A1 - Device for measuring off lengths of wood to be sawn off - Google Patents

Abstract

This invention relates to the woodworking industry. The purpose of the invention is to simplify the design. The device has a spring-loaded clamp fixed on axis 4 and 6- / 4 keys with adjustable stops 7. The stops are controlled by cams 13 mounted on axis 12. Cams 13 interact with keys 6. Keys 6 are made with sequential mutual engagement by means of keyboards. During work, through the cam 13, the machine tool operator presses the required pad with the corresponding stop. In this case, all previous stops are raised, occupying the position Open. The strap being machined is advanced as far as it is in the down position. When the keypad is released, the plank is locked. It is pressed down by the action of springs and clamps, which are raised. The bar is fed to the saw. 3 pcs. i cl

The invention relates to the woodworking industry, in particular, to devices for frozen lengths.

The purpose of the invention is to simplify the design of the device.

 Fig. 1 shows the device; the view in Fig. 2 is the same, top view; on fig.Z - section aa in figure 2.

The device is mounted on the guide bar 1, moving g to the groove of a circular machine with the ability to adjust perpendicular to the PIPA plane, and includes a supporting table 2 with a milled quarter to base the processed strap, support 3, axis 4, fixed on the axis with the possibility of limited rotation. spring-loaded clamp 5 and keys 6 with adjustable stops 7, demarcation sleeves 8, clamping washer 9, nut with locknut 10 key pads 1G, cam axis 13 of rotation 13, intermediate sleeves 14 and support block about 15.

The device works as follows.

The clamp 5 and all keys 6 of the stops 7 are made with successive mutual engagement, for example, by means of keyboards 1 1 and are controlled with one hand of the machine tool located on the support bar 15. The machine operator presses the required keypad 11 and the corresponding stop, all previous stops and the clamp 5 are raised, occupying the Open position (Fig. 3).

With the other hand, the machine tool operator pushes the workable bar at a quarter, selected in the support table 2 of the device, advancing it to the stop 7, which is in the lower working position.

Then, the release of the keyboard pad, the strap being machined is fixed, the presser 5 and the stops that have been lifted are lowered onto it under the action of springs, and the strap is fed to the saw. In the Open position, the stops are not fixed, they are held by the cam.

When setting up the machine, the stops 7 are set exactly to the required dimensions of the length of the segments, multiple to the width of the bar.

The device allows you to quickly select the required dimensions and cut the laths with increased accuracy. It can successfully be applied on the machine CO-70 and similar to it for processing rejected strips of the front surface in the production of modern parquet products.

Recycling rejected slats allows you to increase the use of wood, reduce the cost of parquet products and improve the appearance of parquet flooring.
