Description

(5) DEVICE FOR DETERMINATION OF CUTTING LENGTHS

one

The invention relates primarily to the woodworking industry and can be used in machine tools for transverse sawing of wood, as well as in cross cutting of rolled sections from metal, plastic and other materials.

A device for measuring the lengths of the blanks is known, comprising a base guiding a ruler for the blanks, a Q rotary shaft with stops fixed to it and a shaft turning mechanism Cl3. The disadvantage of this device is the limited number of measured lengths. 5

It is also known a device for measuring the length of workpieces, comprising a base, a guide ruler for workpieces, a guide with a slide, having a stop and a screw shaft with a mechanism for its rotation, and a nut for moving the stop C 2 3 The disadvantage of this device is its low productivity due to increased time-consuming adjustment to size.

The purpose of the invention is to increase productivity by reducing the adjustment time to size.

This is achieved by the fact that the device is equipped with additional sliders with stops and nuts located respectively on the guide and screw shaft, the stops being rotatable relative to the guide, and the nuts have clamps for interacting with the stops.

Clamps are made in the form of grooves on the outer surface of the nuts.

FIG. 1 shows the proposed device a general view; in fig. 2, section A-A in FIG. one; in fig. 3 section bb in fig. 2

The device contains a guide line 1 for blanks, on which a guide 2 with sliders and stops 3 and C are mounted on them, as well as a screw shaft consisting

of two interconnected screws 5 and 6 with nuts 7. On screw 6 a screw shaft rotation mechanism is fixed, made in the form of a flywheel 8, with which screws are rotated. The stop C on the screw 5 (see Fig. 1} is shown in the folded down position. The stop 3 differs from the stop in that its working plane is displaced towards the cutting plane to allow its installation against the intermediate support.

The distance from the working plane of the stops to the plane P of the cut determines the size of the cut workpiece. The nuts have locking pins for interacting with the stops, made in the form of rectangular grooves on their surfaces, into which the stop is placed in the working position. Each of the nuts 7 has the ability to rotate freely on the screw, moving along the guide line 1 from one working position to another and fixed from rotation when the emphasis is placed in the groove on its outer surface. The accuracy of installation is determined by the ratio of the pitch of the screw to the number of grooves on the outer surface of the nut. Screws 5 and 6 are fixed against longitudinal displacements in the supports on guide rail 1, but can be rotated using the handwheel 8, making an accurate adjustment of the y-nut 7 with the support 3 or k fixed on it to the required size. The operation of the device is as follows. When the support is folded down by rotating the nut 7 with a hand, it produces-40 with its installation at the required size, one of the stops moves along the guide line 1 along the guide 2 and is installed in the grooves on the nut 7. parts of the guide bar 1. If necessary, adjustments are made by turning the nut 7 with the support folded down to 1/2 or 1 / turn or more.

Claims (2)

During operation, any stop can quickly fold back or move from one nut to another, pre-installed to the desired size. The rotation of the nuts 7 can be made only when the emphasis is folded. The working bed {eiii can simultaneously have several lugs having different outreach from the guide ruler 1, which makes it possible to sequentially cut a piece of workpieces of several predetermined sizes. Claim 1. A device for measuring the lengths of the blanks, comprising a base, a guide ruler for the blanks, a guide with a slide, having a stop and a screw shaft with its mechanism of rotation, and a nut for moving the stop, characterized in that, in order to increase productivity by reducing the setting time for size, the device is equipped with additional sliders with stops and nuts located respectively on the guide and screw shaft, the stops being made rotatable relative to the guide, and the nuts have clamps for taking and actions with stops., 2. The device according to claim 1, about tons of l and c is that the latches are made in the form of grooves on the outer surface of the nuts, Sources of information taken into account during the examination 1.
