Description

MILLING WOODWORKING MACHINE WITH UPPER SPINDLE LOCATION

The utility model relates to the woodworking industry, in particular, to equipment for the manufacture of relief products and can be used in the manufacture of furniture, building elements and consumer goods.

A device for the manufacture of relief products (AS USSR No. 1486343 MKI 4 V27C% o, dated 06.15.89), including a bed with a movable table, a support with spindles and power cylinders, horizontal guides for the support located on the bed, a vertical displacement unit spindles made in the form of a vertically movable rod arranged along a horizontal guide with adjustable stops mounted on it under the power cylinders, while the spindles have restrictive fixed in front of the adjustable stops ystupy.

The device has a rather complex kinematic scheme with a large number of transmission links, which reduces the reliability of the device and increases its metal consumption.

In addition, the movement of the table, which is a massive part, does not allow to achieve the specified processing accuracy due to the inertia of this movement, which reduces the quality of processing.

The closest to the claimed technical essence and the achieved result is a milling and copying machine with an upper spindle arrangement (AS USSR No. 1468752, MKI 4V27S% 2 from 03.30.89).

The machine includes a bed with a rotating table with a copier installed on it, a milling head mounted on the portal with the possibility of vertical and horizontal movement along

MKI 6V 27S / 02

corresponding guides relative to the portal on which they are made, drives of vertical and horizontal movement of the milling head, copy rollers mounted symmetrically relative to the axis of the milling cutter on the bracket, having a movement and fixing mechanism, and means for controlling the movement of the milling head in the vertical direction in the form of a pneumatic cylinder and in the horizontal direction (in the form of a spring).

The disadvantage of this machine is the need to make a copier in each case of manufacturing a particular product, which requires additional costs and reduces productivity.

Motion control with a pneumatic cylinder requires compressed air. Moving the part during its milling is done manually, which leads to inaccuracies in processing and degrades the quality of processing. In addition, the movement of the milling head along the vertical and horizontal guides relative to the rotating table leads to inaccuracies in the processing of the part and limits the functionality of the machine.

The utility model is based on the task of creating a milling woodworking machine with greater productivity and versatility while improving the quality of processed products and expanding the functionality of the machine.

The problem is solved in that a milling woodworking machine with an upper spindle arrangement, including a bed with a table mounted on it, a milling head located above it, mounted on a beam with the possibility of longitudinal and vertical movement along the respective guides, vertical and longitudinal movement drives and movement controls the milling head is additionally equipped with a lateral movement drive and a corresponding guide.

on which the milling head is mounted with the possibility of moving along it, and the table is fixedly mounted on the bed.

The controls for moving the milling head are made in the form of a numerical control system.

The system of numerical profammnoy control is an electronic control unit for the automatic movement of the milling head on the workpiece.

The supply of the machine with a drive and a guide for lateral movement, and the installation of the milling head with the ability to move along the latter, made it possible to ensure the movement of the milling head in all directions relative to the workpiece mounted on a table fixedly mounted on the bed.

All this allowed to increase the accuracy and versatility of machining parts on this machine.

The implementation of the control system in the form of an electronic unit that controls the automatic movement of the milling head along the workpiece in accordance with a given program, has improved the productivity and quality of processing due to the accurate and smooth movement of the milling head at a given speed, which ensures uniform processing, ensuring the quality of the latter.

The drawing shows the proposed milling woodworking machine.

The machine includes a bed 7 with a table 2 fixed on it with clamping devices 5, a milling head 4 located above it, mounted on a supporting beam 5, with the possibility of vertical longitudinal and transverse movement along the respective guides 6, 7 and §. The machine also contains a vertical drive 9, a longitudinal drive 10 and a lateral movement drive 11 of the milling head 4. The numerical control system is made in the form of a CNC device 12 into which the program for processing the part is entered, and

cabinets 13 electroautomatics. The machine is equipped with an air duct 14 for removing dust. The machine operates as follows.

The workpiece (not shown in the drawing) is placed on the desktop 2 and secured by clamping devices 3 in a stationary position.

A program for processing a workpiece is entered into the device 12 of numerical program control.

After giving a command to start processing from the device 12, through the cabinets 13 of the electric automation, commands are sent to the drives 9, 10 VL 11, which move along the guides 6,7 and 8 the beam 5 with the milling head 4 fixed on it, processing the workpiece according to a given profile. During operation, dust is removed through a special duct 14. After processing, the finished part is removed from the table 2.
