Description

The invention relates to the equipment of the woodworking industry and can be used in tongue-and-groove planing machines for fixing the stumps of the baths.

A device for a tongue-treading machine is known for fixing vanches, consisting of hollow slabs with suction cups embedded in them, made in the form of cylindrical sleeves for supplying compressed air and creating a vacuum 1.

The drawbacks of the device consist in the unreliable fixing of the vandes ostrus, which are experiencing enormous loads when cutting the spike layer (sheet) from them, as well as their unreliable holding due to the absence of an ideal surface for the suction cup.

It is also known to have a device for a tonging machine for fixing vanches, including a frame, a support with guides, tire clamps, sliders, and a drive 2.

A disadvantage of the known device is the design complexity, i.e. the presence of a drive for moving the clamps in the vertical direction, as well as a compressor unit, increasing power consumption, increasing the bulkiness of the device, complicating machine control and servicing the pressure vessel of the compressor unit that does not improve the quality of the veneer, since air escapes at a place of lower resistance, i.e. . side openings of hollow tires. In this case, during the operation of the machine, friction is increased over the vanishing flap, which causes an increase in the caliper drive power and power consumption.

In addition, the device is characterized by a lack of reliability of the clamps due to the presence of a gear during the creation of a suitable force on the vanches, because the toothed slide of the slide rotates the gear in which the corresponding shoulder is formed, which is the radius of this gear.

. The purpose of the invention is to simplify the design, reduce power consumption and increase the reliability of the device.

This goal is achieved by the fact that in a device for a tongue-treading machine for fixing vanches, including a bed, a support with guides, clamps with tires, sliders and a drive, the sliders are made with oval grooves, and the guide supports are with side holes, which are offset , yen axis with eccentrics fixed on it, placed in

oval grooves of the sliders, with the tire of each clamp made of a U-shaped cross section with a number of lateral holes along its length, in which axles with rollers are installed.

FIG. 1 shows the proposed device, side view; in fig. 2 is a view A of FIG. one; in fig. 3 is a section BB in FIG. one; in fig. 4 — node I in FIG. 1 (with eccentric).

The device contains guides of 1 L-shaped section, fixed on the support 2 of the clamping ruler. In the guides 1 there are placed T-shaped slides 3, made with oval recesses 4, in which eccentrics 5 are placed, fixed on a common axis 6, mounted in the openings 7 of the guides 1 and equipped with an ejector 8, with which the vertical clamps 9 are moved .In tires 10 of each clamp 9 are placed

rollers 11, axles 12 of which are mounted in holes 13 located along the entire length of the side walls 14 of each tire 11.

When shaking off the scraps of vanches 15, the rollers And hold the latter from a vertical shift upwards.

The device works as follows.

At the beginning of the work of the planer machine, the device is above the vanches 15 (10-20 mm), i.e. shtruvalom 8 turned

axis 12 so that the eccentrics 5 are raised to the upper position of the slide blocks 3. After the vanches 15 become ots, i.e. compacted to a thickness of 50-70 mm, the planer planing is stopped and the steering wheel 8 rotates the axis 12, and

together with it, the eccentrics 5, which translate and fix in the lower position the sliders 3, after which they turn on the tongue-and-groove machine to continue working. At this position of the device during

the caliper 2 moves in one direction or another, the rollers 11, rolling over the vaned vanes 15, keep the latter from vertical shear (jumping upwards), which ensures that the vanches 15 are pulled to the minimum (5-8 mm if possible)

thickness. After finishing planing the ovules with a 15 by the steering wheel 8, the sliders 3 are moved to the upper position, the remaining oysters of the vanches 15 are removed, new baths are installed and the cycle is repeated.

The advantages of the proposed device are in simplifying its design, in the absence of a drive for moving the clamps, as well as a compressor unit, in excluding the maintenance of vessels under

pressure, in reducing the bulkiness, in the reliability of the clamps and in simplifying the control of the machine.
