Description

(54) DEVICE FOR TREATMENT OF FIXED FURNITURE

one

The invention relates to the field of construction H can be used to process parabolic and radius cylindrical elements with large curvature radii, for example, for preparatory diamond turning in v-shaped metal optical mirrors ..

Devices for machining shaped surfaces are known, comprising a spindle mounted in the housing for rotation and swing, carrying a tool mixed with respect to the axis of rotation, a mechanism for interconnecting the rotation between and a swing of the spindle, and an installation table having a feed mechanism i

The disadvantage of such devices is the limited length of the chain that can be processed at a given value of 70 tool overhang.

I send the invention to the possibility of processing products of unlimited length.

This target is achieved due to the fact that the device is equipped with piezoelements, on which a table (or instrument) is installed, and with a sensor for the exit of the instrument from the product, connected via a control system to the piezoelectric elements.

The present invention is illustrated in the drawings, which show a general view of the device with a different arrangement of piezoelements: FIG. 1 - a table is installed on the piezo elements, a radius of 1 {cylinder} is processed; in fig. 2 - a tool is installed on the piezo element, the parabolic board is machined.

Claims (1)

The device consists of spindle 1 ,. The tool 3 is non-drift relative to the axis of rotation 2. The spindle 1 is mounted in the cortus 4 with the possibility of cutting movement around its axis 2 and swinging along with the housing 4 on axis 5. Axis 5 is located perpendicular to axis 2 of rotation. On the cutter path, product 6 is installed. At the upper end, the spindle is made, with an eccentricity about the axis of rotation of the spindle, the support 7, hinged forwards in a slider 8, which is mounted in the guides 9 with the possibility of movement along and around the axis of these guides . The axis of the guides 9 is parallel to the axis of swing 5. At the upper end of the spindle, a flag 10 is also set, which acts upon the rotation of the spindle on the sensor 11 of the tool exit from the product. Table 12 with the product 6 is mixed by the feed mechanism (in the figures it is not shown in the horizontal plane along the guides 13 mounted on the piezo elements 14, which are fixed on the base 15. In the embodiment of the device shown in Fig. 2, the guides 13 are fixed directly but on the base 15, a piezoelectric element 17 is mounted between the tool 3 and the tool holder 16. The device works as follows: Spindle 1 is rotated. In this case, the support 7 rotates with the pin and moves the slider 8. The upper end of the tip is swung on the axis 5 into the pl In this case, tool 3 describes the trajectory in space, the projection of which onto the drawing plane of this parabola, and onto the plane perpendicular to the drawing plane - part of a circle. and it moves progressively with the feeder. When the tool 3 rotates, it encounters a product 6, crashes into it, removes the specified allowance, and leaves the product. When the tool leaves the product, the 1O flag acts on the sensor 11 (for example, Rokhod between the source of light and photocell). The signal from the sensor transmits to the control system, where the electrical signal applied to the piezo elements is discharged. The piezoelectric elements are compressed, while the guides 13 and the table 12 with the product 6 are lowered. Tool 3 with further movement passes over the previously treated surface, without touching it. After the tool passes over the product, the control removes the signal on the piezoelectric elements and they return to their original position. In the second variant of the device, the piezoelectric element, squeezing, lifts the tool when it passes over the previously treated surface of the product. The use of the present invention will allow the treatment of a product with a length of 2OO mm without increasing the dimensions of the device. Claims An apparatus for machining shaped surfaces, comprising a spindle mounted and rotatably rocking, carrying a tool displaced relative to an axis of rotation, a mechanism interconnecting the rotation and rocking of the spindle, and a table for setting the product having a feed mechanism, TL .and that, in order to be able to process products of unlimited length, the device is equipped with piezoelectric elements on which a table is mounted. or a tool, and a sensor for the exit of a tool from an article and, associated with 5pravleni through the system. piezo elements.
