SU8634A1 - Safety device for milling machines - Google Patents

Description

The proposed safety device is intended for a woodworking milling machine.

In FIG. 1 shows a side view of the machine with the proposed device; FIG. 2 is a top view; FIG. 3 is a front view and FIG. 4-part slider.

The proposed device (Figs. 1, 2, and 3) consists of a milling machine located on the table 1, on either side of the router 2, on one side of it, rollers 3 mounted on axles 4 having sliders 5. Machine table 1 (fig 4) is provided with longitudinal guide grooves 7, in which sliders 5 carrying lugs 7 are connected, connected with cables 8-8. In the right part of the machine (Fig. 1 and 2) there are cables 8-8, coming from rollers 3 in grooves b, skirting blocks 9-9 and 10-10, and fitted with end weights 11-11; In the left part of the machine there are cables 8-8, coming from the rollers 3, also in the grooves 6, which bend around blocks 12-12 and 13-13 and are fixed on the crossbar 14 (Fig. 3), which is connected in turn by a cable, bending around, blocks 15, 16, with a pedal lever 17. On the table 1 machine

guide bar 18 is installed.

In the interval between the guide ruler 18 and the rollers 3 retracted using the pedals of the lever 17, the workpiece is turned on and clamped by the rollers 3 under the influence of weights 11-11 with the pedal lever released 17. As the object passes, the first roller 3 moves to the ruler 18 and removes the arm a worker delivering an item; another video finishes processing the item.

When machining curved surfaces, the ruler 18 is removed and the product is brought to the router 2 on one roller-3; In order to fix the roller 3 fixedly, stoppers are installed in the transverse sockets 19 of the groove 6. The product is pressed by the worker's hand to the router 2 and the roller 3, intended to prevent the product from rotating with the router 2. Another roller is removed from the table 1 of the machine during similar work.

The subject of the patent.

1. Safety device for milling machines, characterized by the use of two located on the one and the other side

router 2, on the side et him, rollers 3, the axes of which are provided with sliders 5, which can mix along the guide grooves 6 selected in the machine table J and bearing lugs 7 for connecting them, with the help of cables 8 thrown through appropriately arranged blocks - with a pull-over load 11,: and on the other - a G cross-member 14, in {turn, connected with the cable with the pedal lever 17, intended,

valuable for retracting the rollers 3 from the router for the purpose of inserting the part being machined between them and the guide bar 18.

2. In the application described in paragraph 1 of the fixture, in the case of working on a milling cutter without a ruler 18 transverse slots 19 at the groove O for placing a stopper in one or another of them, in order to fix the deviation of the corresponding roller 3.
