RU197079U1 - DEVICE FOR EDITING THE END OF THE GRINDING CIRCLE AT THE THREAD-GRINDING MACHINE - Google Patents

Abstract

The utility model relates to mechanical engineering and can be used to dress the grinding wheel on thread grinding machines of all types, having a table with guides and a handle for moving the rotating grinding wheel. The device comprises a L-shaped case with a groove in the upper part, made with the possibility of installation on the guides of the machine table, and a holder located in the groove with an opening at the end, in which the bracket with a diamond roller is mounted with the possibility of rotation by 360 ° and fixing in any position. A groove is made in the lower part of the said casing with a cam installed in it that rotates freely on the axis to fix the casing on the table guides using the clamping screw, and the grinding wheel has the possibility of reciprocating movement with the handle relative to the diamond roller. As a result, dressing of the end face of the grinding wheel is ensured, which allows for high-precision work on the miter and grinding of particularly precise parts in one installation. 3 ill.

Description

The utility model relates to the processing of metals by cutting, in particular to dressing the grinding wheel on thread-grinding machines of all types, and can be used in various branches of engineering for the final operations of the technological process of manufacturing parts.

An analogue of the claimed utility model is a 5822M thread grinding machine with a built-in standard device for dressing a grinding wheel (see Tulpa S. M. Thread-grinding work, M., Higher School, 1973, pp. 168-172, Fig. 100 b)), which dressing the profile or periphery of the grinding wheel. A significant drawback of such a design scheme is that the installed diamond rods in the dressing device allow dressing to be performed only on the profile and periphery of the grinding wheel, and it is impossible to edit the end face of the wheel. Editing the end face is necessary to perform high-precision work on the cutting of critical parts to ensure accurate (up to 0.01 mm) mutually perpendicular position of the end face of the part and the axis of the surface to be ground.

The objective of the proposed utility model is to provide the possibility of dressing the end face of the grinding wheel on a thread grinding machine to ensure that milling and grinding work is performed in one installation.

The technical result is achieved due to the fact that the device for dressing the end face of the grinding wheel on a thread grinding machine contains a L-shaped body with a groove in the upper part, made with the possibility of installation on the guides of the machine table, and a holder located in the groove with an opening at the end in which it is installed with the possibility of rotation through 360 ° and fixing in any position, an arm with a diamond roller, while in the lower part of the said housing there is a groove with a cam mounted freely rotating on the axis for fixing the case on the table guides with the help of a clamping screw, and the grinding wheel has the ability to reciprocate with the help of the handle relative to the diamond roller with the provision of editing its end.

 Figure 1 and figure 2 shows a device for dressing the end face of a grinding wheel on a thread grinding machine (side view and top view, respectively), figure 3 shows a bracket with a diamond roller, where:

1 - L-shaped housing,

2 - holder

3 - pressure plate

4 - bracket

5 - diamond roller,

6 - cam

7 - axis of rotation of the cam,

8 - clamping screw,

9 - guides of the table of a grinding machine,

10 - grinding wheel

11 - handle to move the grinding wheel.

In the static position, the device consists of the following components: in the upper part of the L-shaped housing 1, a groove is made in which the holder 2 is mounted and secured by the pressure plates 3. A bracket 4 is installed in the hole at the end of the holder 2, in which the diamond roller 5 is installed. B the lower part of the housing 1 has a groove for installing the cam 6, which rotates freely on its axis 7. The position of the cam 6 is regulated by the clamping screw 8.

The device operates as follows. On the guides 9 of the table of the grinding machine, a L-shaped housing 1 is installed and fixed with the cam 6 and the clamping screw 8 near the grinding wheel 10. Moving the table of the grinding machine, the device moves to the grinding wheel 10 so that the diamond roller 5 touches the end surface of the grinding wheel 10 Next, by alternately rotating the handle 11, the grinding wheel 10 is reciprocatingly moved, which ensures that its end surface is straightened. To edit the opposite end, the grinding wheel 10 is taken to the maximum “back” position, then the device moves on the other side of the grinding wheel 10, the bracket 4, with the diamond roller installed, rotates 180 °. Next, the dressing of the end face of the grinding wheel 10 is performed in the same manner as described above.

Claims (1)

A device for dressing the end face of the grinding wheel on a thread grinding machine having a table with guides and a handle for moving the rotating grinding wheel, characterized in that it contains a L-shaped body with a groove in the upper part, configured to be mounted on the guides of the machine table, and located in a groove holder with a hole at the end, in which a bracket with a diamond roller is mounted with the possibility of rotation by 360 ° and fixing in any position, while a groove is made in the lower part of the housing copulating therein freely rotatable on the cam axis for fixing the housing on the guide section via the pressing screw, and the grinding wheel has the possibility of reciprocating movement by means of the handle relative to the diamond roll dressing ensuring its end.
