Description

I

The invention relates to mechanical engineering and can be used in multi-domain processing.

Known machines for two-sided grinding of the ends of ll.

The disadvantage of these devices is their complexity.

Also known is a machine containing D1 grinding headstock mounted on a bed, grinding wheels fixed in the grinding heads spindles, tools for grinding wheels grinding and a device for determining the position of the ends of grinding wheels containing a measuring ruler fixed on grinding heads, moving indicators moving ruler, indicator and stops, mounted on grinding heads With the disadvantage of the known machine is the length of the changeover time for multi-nozzle abotke. .

The purpose of the invention is to reduce the changeover time during multiprocessing.

The goal is achieved by the fact that the machine is equipped with carriages mounted for movement relative to the grinding headstocks, four wear indicators, one pair of which is fixedly mounted on the grinding headstock and the other on the frame,

10 with two indicators Editing fixedly mounted on the frame and indexes Product height, and Zero fixed on the frame with the possibility of adjustment movement along the measuring line, while the tools for straightening grinding wheels accommodate. on the frame, the Pointers Circles are not fixed on the carriages, the stops are mounted on the frame with the possibility

Claims (2)

20 interaction with the carriages, the measuring ruler is fixed on the frame and provided with a zero mark, corresponding to the position of the plane, the grinding of new grinding wheels, the distance between the indicators, and the height between the indicators and Wear is equal to the maximum allowable wear of the circle, and the distance between two indicators Editing is equal to the distance between cutting 1 µm by the edges of the tools for dressing grinding wheels. The drawing shows the proposed machine. The machine contains grinding headstocks with carriages 2 mounted on frame 4. Pointers 3 are fixedly placed on carriages 3 Circle, Grinding wheels 5 are fixed on spindle and grinding heads, Tools for straightening grinding wheels (not shown) and a device for determining the position of the ends of the wheels, including. measuring it with a 1 line ruler 6 with a zero mark, pointers 7 Editing and 8 Wear, fixedly on the frame, pointers 9 Product height, 10 Zero and IIK 1.2 stops are fixed on the frame with the measurement tool the main line, with the stop 11 placed under the isasazatel. Height of the articles, 12 above the pointer Zero Pointers 13 Wear and tear are fixed on the grinding heads, and the y1-sazatel1 9 Height of the product and 8 Wear and asazateli 10 Zero and 8 Wear and a distance equal to the maximum allowable wear of the wheel, and indicators 7 Editing - at a distance equal to the distance between the cutting edges of the tools for dressing grinding wheels. The device works as follows. When new grinding wheels 5 are installed in the VIX position, the zero mark is put on the neck 6. Layout 2 with indicators 3 The circle is aligned with indicators 13 Wear, fixes on the grinding heads 1. Indicator 9 The height of the product is set on the ruler 6 at a mark equal to the height of the workpiece and fixed. The indicators Circle and Height of the product are combined by moving the upper grinding head, while the stop 1 1 interacts with the carriage 2. As the grinding wheel vi3Hoca, the grinding head 1 moves with the pointer 8 Wear, and the pointer 3 The wheel remains stationary, since the carriage 2, on which it is fixed, keeps the support 11 against the pointer 9 of the height of the article from moving. The distance between indicators 3 and 13 determines the actual wear of the grinding wheel. A steep change is carried out when combining pointers 13 and 8 Wear. To edit the grinding wheels, the grinding heads 1 are moved to the combination of the 3 Circle and 7 Editing indicators. During the dressing, the grinding headstocks are fed to the correct tools for the amount of dressing, which is marked on the ruler 6. After the dressing, the grinding headstock is fed to the coincidence position of the pointer 3 The circle with the ruler's line below the pointer 9 The height of the item by the dressing value .. When changing the machine to the product to another height, the pointer 9 is moved by the height of the product to a new mark on line 6, corresponding to the height of the new product, and the upper grinding wheel is moved to Falling of the 3 Circle and 9 Product Height Pointers circles with enclosures closed and without appropriate measurements. Formula of the invention Bilateral face grinder containing grinding headstock installed on the bed, grinding wheels mounted on the spindle of grinding heads, tools for dressing grinding wheels and a device for determining the position of the ends of the circles, including the measuring line, moving indicators Circle moving along the line, and stops, characterized in that, in order to reduce the setup time of the machine and readjust it during multi-nomenclature processing, it is equipped with carriages, installed with The ability to move relative to the helium 53 grinding heads, four indicators Wear, one pair of which is fixed on the grinding heads and the other on the frame, two Heads Edit, fixedly mounted on the frame, and the Height and Zero indicators mounted on frame with the possibility of adjustment movement along the measuring ruler, with the tools for dressing grinding wheels mounted on the frame, the circle indicators are fixed on the carriages, the stops are mounted on the frame 5 "with Interaction with carriages, measuring line attached to the frame and equipped with a zero mark.
