Description

The utility model relates to the field of machine tools, in particular to turning woodworking machines, and can be used for turning parts from wood.

Known and selected as a prototype is a woodworking lathe containing a bed, an electric motor with a kinematically connected front (spindle) headstock with step-by-step adjustment of the spindle speed, as well as a tailstock and tool holder [A.S. USSR No. 1787768, IPC В 27 С 7/00, 1993].

The disadvantages of the known woodworking lathe are limited functionality (you cannot change the axis of rotation of the workpiece relative to the bed), as well as the complexity of the step-by-step regulation of the number of revolutions of rotation of the spindle (it is necessary to turn off the motor and reinstall the belt on the step pulleys).

The objective of the claimed utility model is to remedy these disadvantages.

The problem is achieved in that in a turning woodworking machine containing a bed, a headstock with a spindle for fastening the center of the headstock with teeth or faceplates kinematically connected to the electric motor via a belt drive, as well as a tailstock and a tool holder installed in the groove of the bed, according to the utility model , the headstock with an electric motor is pivotally mounted on the bed with the possibility of rotation in a horizontal plane up to 180 ° and fixing in predetermined intermediate and extreme positions, etc. This tool holder is mounted on a removable rotating bracket, and the headstock is provided with a smooth lockable adjusting spindle speed.

To install the tool holder in front of the headstock deployed 180 ° (when machining the end surface of the workpiece fixed to the faceplate), the machine is equipped with a bed extension.

To facilitate the design of a woodworking lathe, its bed is mounted on a structural support assembled from thin-walled profiles.

The utility model is illustrated in the drawing, which schematically shows a General view of the inventive turning woodworking machine.

The list of items in the drawing

1 - bed;

2 - front headstock;

3 - spindle of the front headstock;

4 - the center of the front headstock with teeth;

5 - electric motor;

6 - handle fixing the position of the headstock;

7 - support tool holder;

8 - tool holder;

9 - tailstock;

10 - the tailstock tailstock;

11 - rotating bracket of the tool holder;

12 - the center of the tailstock;

13 - flywheel axial movement of the pin;

14 - handle for fixing the support of the tool holder;

15 - handle for fixing the tool holder bracket;

16 - handle for fixing the tool holder;

17 - handle fixing the position of the tailstock;

18 - handle fixing pintles of the tailstock;

19 - bed support;

20 - knob for controlling the spindle speed of the headstock;

21 - bed extension.

The woodworking lathe includes a bed 1 with a headstock 2 mounted on it, equipped with a spindle 3, in which a faceplate or center 4 of the front headstock with teeth can be attached. The spindle 3 is kinematically connected via a variator to the shaft of the electric motor 5. The electric motor with the headstock 2 are mounted on the bed 1 with the possibility of an adjustable fixed turn in the horizontal plane through 180 °. The headstock 2 has five main positions: position 0 ° - for all operations using

spindle and tailstock, position 60 ° / 90 ° / 120 ° - when working using the faceplate, position 180 ° - when working using the faceplate and using a bed extension. To ensure a controlled position of the headstock 2, it is equipped with a handle 6 fixation. In the frame 1, a groove is made in which the support 7 of the tool holder 8 and the tailstock 9 are mounted with the possibility of longitudinal movement. The tool holder 8 is mounted on the rotating bracket 10. The bracket 10 is removable and the tool holder 8 can be reinstalled in the support 7. The tailstock 9 has a pin 11, in which the center of the tailstock 12 is installed, provided with a shank in the form of a cone, as well as a flywheel 13 of axial movement of the quill. The position of the tool holder support is fixed by the handle 14, the bracket 10 - by the handle 15, the tool holder - by the handle 16, the tailstock - by the handle 17, the pins - by the handle 18.

Preparation of a woodworking lathe for work is as follows.

The preassembled machine is mounted on a supporting support 19 made of thin-walled profiles. The center of the headstock 2 and the center of the tailstock 8 have a cone. To install them, insert the cone into the mating conical openings of the front and rear headstock with a solid strong movement. They will be further fixed when the workpiece is inserted between the centers.

To change the spindle speed of the headstock, turn the knob 20 to control the spindle speed of the headstock to the desired setting on the speed scale (the machine has ten fixed speeds). In this case, the spindle speed should be changed only when the motor is running.

Before turning off the machine, turn knob 20 to minimum speed. The bed 1 of the machine is equipped with a removable extension 21, on which the support 7 of the tool holder 8 with the bracket 10 can be reinstalled, when the headstock 2 is rotated 180 ° and the part mounted on the faceplate is processed. If this is not required, then the extension 21 of the frame 1 is not installed.

Turning of the workpiece in the centers is carried out in the traditional way using well-known manual wood turning tools.

When processing a workpiece mounted on the faceplate, the claimed design of the lathe allows you to expand its functionality by adjustable changes in the angle of rotation of the workpiece relative to the bed. So, when installing the headstock 2 at an angle of 90 °, you can process large diameter workpieces (the workpiece is located on the side of the bed 1 and does not touch it). When installed at an angle of 180 °, the bed 1 does not interfere with the free access of the turner to the workpiece, which increases the convenience and safety of work. The installation of the headstock 2 in intermediate positions 60 ° and 120 ° also allows you to process large diameter workpieces (for example, to make internal sampling in details such as a bowl, egg cup, etc.).

The use of the claimed utility model significantly expands the functionality of a turning woodworking machine, and also increases its safety and convenience in its operation.
