Abstract

The invention relates to the woodworking industry. The purpose of the invention is to extend technologic possibilities and simplify the construction of woodworking machines. This is achieved by:1) the lifting device for the woodworking machine, which comprises a sleeve mounted on the working desk and moving upright on the cylindrical surface of a milling column, and fastening screw, moving along the deflecting gauge, which is positioned in parallel with a spindle in the milling column housing. The fastening screw is leaned to the regulating ring of the sleeve and the ring moves along the milling column outer surface screw;2) the deflection mechanism for supports, which comprises deflecting gauges, positioned on the working desk surface, perpendicular to the direction of the development movement and screwed sleeve, which moves along the screwed rod of the deflection gauge, mounted on the lower part of the desk plane;3) a thickening machine, which comprises a mobile support, screwed and sleeved to the front of the blade shaft (the screwed sleeve moves along the deflection gauge perpendicularly to the direction of the development movement by means of a screwed rod) and stiff pushing plate, screwed to the sleeve in front of the blade shaft (the sleeve moves along deflecting gauges perpendicularly to the direction of the development movement be means of a screwed rod).

Description

The invention relates to the woodworking industry and can be applied to the processing of wood raw materials.

There is a well-known universal woodworking machine consisting of a rack mounted on a cutting table and a planing unit consisting of a casing with front and rear movable tables, a working shaft with planing knives and a blade tip (USSR Certificate No. 1087331). .

The main disadvantage of these machines is their limited technological capabilities.

there are also known combination woodworking machines consisting of rack, milling, planing, drilling and grinding units with tables, guides and stops and actuators (USSR Auth. No. 952585).

The disadvantage of these machines is the complex design.

The object of the invention is to expand the technological possibilities and simplify the construction of the machine tool.

The machine construction consists of two main assemblies: an electric drive I with stepped pulleys 2 mounted on a metal plate 3 and a milling column 4 with stepped pulleys mounted perpendicular to the other metal plate 5. Both plates have two holes guiding notches 6, cut parallel to the smaller plate. a side for tensioning and balancing the V-belt 28 by screwing them to two Γ-shaped square cross-section tubes 7. A milling table is provided with a work table 8 consisting of a plate with a hole for the milling column and a bushing 9 with a locking screw 10. Parallel to the smaller half there are holes for guiding 27 for mounting and adjusting the supports. Attached to the lower part of the table are two screw arms 16,25, which move the bushes for adjusting the front and thigh supports. On the outside of the milling column there is a thread for moving the support ring II, which rests on the bushing, to adjust the distance from the base of the workbench to the upper point of the spindle 21. Also in the outer part of the milling column, a guide notch is cut parallel to the spindle and moves the screw 10, which secures the table in the required position.

The desk 13 is provided with screw-mounted front 13 and rear 14 removable supports adjustable by narrow guiding notches 27 cut in the work table perpendicular to the direction of movement and the front support is movable. The table is also fitted with a rheumatic device consisting of a rigid plate 15 and a movable support, bolted to a threaded bushing moving in a narrow guide cut at the work desk by means of a screw pull, which allows the size of the workpiece to be adjusted. The workbench also includes removable guides 17 with a trolley 18 on which is mounted an eccentric clamp 19 with pre-adjustable locking angle adjustment, as well as a detachable device

Workflow of Universal Woodworking Machines.

For milling, the spindle 21 is fitted with a circular milling cutter and the adjusting ring II adjusts the distance from the base of the workbench 8 to the cutting edge of the milling cutter (height adjustment), followed by the front 13 and rear 14 supports and adjustable workpiece depth. The trapezoidal belt 28 and the stepped pulleys 2 select the required spindle speed for actuation of gear I and process the workpiece.

Instead of the milling cutter, a circular saw is mounted on the spindle, and if necessary, a comb attachment (not shown) is attached to the table without the front and rear supports, the required spindle speed, the gear is engaged and the workpiece is cut.

Template copying milling is performed by using a press-fastening machine on the workbench, attaching a circular cutter to the spindle, nailing the workpiece to the template and trimming.

For planing work, the spindle head 23 with blades 24 is mounted on the spindle, the back supports 14 (non-sliding) and the front 13 (movable) are attached to the work table, the required spindle speed is selected, the gear is engaged and the workpiece is processed. When the front support is moving, the depth of the planing is adjusted by means of a guide screw.

A rigid press plate 15 is fastened to the table in place of the front support, and the front movable support 13 is mounted in front of the planing head parallel to the rear support for travel operations. As the front support moves, the workpiece guide adjusts by means of a guide screw 16.

To perform the ditching work, a table-mounted guide 17 is provided with a trolley 18 on which an eccentric clamp 19 attaches the workpiece, a cutting tool is mounted on the spindle, the actuator is actuated and the workpiece is processed.

For planer-blade sharpening, a carriage 18 is provided with a device for pressing the blades 20, and a circular sharpening stone is attached to the spindle. The height of the stone in relation to the blades is regulated by the adjusting ring II on the milling column. The knife sharpening angle is adjusted by a screw 26 located on the carriage.
