Abstract

A UNIVERSAL WOODWORKING MACHINE, including a frame with a saw table mounted on it and a jointing unit consisting of a housing with front and rear movable tables, a working shaft with jointing knives and a nozzle with a saw disk, a locking device to eliminate the possibility of simultaneous working with two tools. and an actuator, characterized in that, in order to improve operational safety, a locking device. made in the form of spring-loaded with respect to the fugowaning unit of the pushers, bearing on one end the stops adjacent to the nozzle of the saw disk, I, and the other end in contact with the cams mounted on the sliding (/) tables of the jointing unit.

Description

The invention relates to the woodworking industry, in particular to universal machines for treating drainesines, used in households and workshops,. A known machine for treating wood materials, including a saw, a sawing and fugging unit, a working shaft with fugging knives and a saw blade, a guard and a drive ij Nedrstatkom this fold is the lack of a device to prevent the simultaneous operation of two tools. A universal woodworking machinej is also known, which includes a frame with a saw table and a jointing unit consisting of a body with front and rear movable tables, a working shaft with jointing blades and a nozzle with a saw disk, a locking device to prevent simultaneous operation of two tools. , fence and drive 21, A disadvantage of the known machine is the low safety of operation. The purpose of the invention is to improve the safety of work. This is achieved by the fact that the device for blocking made in the form of spring-loaded with respect to the fugowaning unit of the pushers 5 carriers at one end of the clamp-yushpe to the saw blade attachment stops, and the arms and the J contact the end of the contact with the cams mounted on the movable tables of the fugie node ani, Hg. 1 shows a diagram of a universal woodworking mill square; front view; in fig. 2 is a view A of FIG. G vig 3 - machine top view; FIG. 4 is a section along the line BB in FIG. 25, FIG. 5 shows a section B-B in FIG. 45 in FIG. 6 — section G-D in FIG. 4; The machine includes a frame 1 on which the saw table 2 and a fugowing unit 3 are installed, consisting of a body 4 with directions 5 and movable front b and rear 7 tables B The fugovogo unit 3 in bearings 8 is fitted with a working wa.p 9 with knives 10 for jointing and a nozzle P with a saw blade 12. To move the movable tables 6 and 7 along the guides 5, screws 13 are used. In the housing 4 parallel to the axis of the working shaft 9 are mounted pushers 14 locking devices 15. Each of the pushers 14 is at one end in contact with a cam 16 mounted respectively on the front 6 and rear 7 movable tables, and on the other ends of the pushers 14 are fixed. Curved stops 17 adjacent to the nozzle 11 of the saw disk 12. On the base 1 there is a spring-loaded fan the guard 18 of the fugowing unit 3, and on the saw table 2 a folding guard 19 of the saw blade 12. The rotation of the working shaft 9 is carried out from the drive 20. The machine works as follows. In the initial position of the fugowing unit 3, the front 6 and rear 7 movable tables are reduced to the center by completely closing the knives 10. For preparing the jointing machine, the movable tables 6 and 7 are moved along the guides 5 with screws 13 so that their height difference corresponds to the required thickness of the removed lay At the same time, the cams 16 connected to the tables 6 and 7 also move and act on the pushers 14. The latter are pivoted and respectively pivot the stops 17, which abut against the nozzle 11. Until the nozzle 11 is removed, the tables cannot be moved apart by the required amount, and therefore, it is not possible to gouge parts. With the removal of the nozzle 11, the tables 6 and 7 are moved apart, fixed, and the jointing unit 3 is ready for gouging the blanks. , To carry out the sawing of the blanks, it is necessary to replace the nozzle 11 with the saw blade 12, and the fugging unit 3 must be returned to its original position. In this case, the stops 17, when converting the tables 6 and 7 together with the pushers 14, following the cams 16, are drawn into the inside of the housing A and onto the shaft 9 install the nozzle T1 with a saw in order to cut the part.

Thus, the machine eliminates the possibility of simultaneous access to two rotating cutting

tools, which ensures safe operation.
