Definitions
- ABSTRACT A device for dressing abrasive wheels, whose essence resides in making the working zone free with a view to utilizing large diameter abrasive wheels and working large-sized articles, characterized by the provision of vertical guide members in a member that carries an abrasive wheel, whereby the holder of a dressing tool, which travels along a guide member inclined at an angle of 45 to the horizon, moves the abrasive wheel towards the article being worked.
- the present invention relates to cutter-grinding machines, and more particularly to devices for dressing abrasive wheels, which are mounted on such machines.
- devices adapted for dressing abrasive wheels and mounted on cutter-grinding machines which comprise a member carrying an abrasive wheel, said member being mounted on the supporting member of the machine with a possibility of moving towards an article being worked, and a holder on which a dressing tool is fixed.
- the holder is mounted so as to be movable along a guide of the supporting member inclined at 45 to the horizon, in such a manner, that the dressing tool, as the grinding wheel becomes worn out, performs a followup motion in a direction perpendicular to the travel of the abrasive wheel towards the article being worked (cf., e.g., German Pat. No. 885,666).
- the holder of the dressing tool is connected with the carrying member by means of a lever with a roller accommodated in a groove made in a projection of the carrying member.
- Such an embodiment of the device does not allow the use of large diameter grinding wheels, or work large-sized articles.
- the object of the present invention is to provide a device for dressing grinding wheels, wherein the connection between the holder of the dressing tool and the carrying member would be effected in such a manner, that the guide inclined at 45 to the horizon should not restrict the working zone of the device, so that it would be possible to use large diameter grinding wheels and work large-sized articles.
- a device for dressing the grinding wheel in the course of its rotation comprising a member carrying said wheel and a holder with a dressing tool performing a followup motion, as the grinding wheel becomes worn out, along a guide of the supporting member, inclined at 45 to the horizon, in a direction perpendicular to the direction of travel of the abrasion wheel towards the article being worked,
- the member carrying the grinding wheel is provided with vertical guides arranged at 45 to the inclined guide of the supporting member, said vertical guides serving for travel of the holder carrying the dressing tool, said holder moving the member carrying the abrasive wheel towards the article being worked, during interaction with the inclined guide of the supporting member.
- this last-mentioned guide being disposed at 45 to the horizon and to the corresponding guide in the holder, the latter proves to be associated with the carrying member with a possibility of a vertical movement.
- the holder of the dressing tool will descend, moving along the inclined guide, and urge the member carrying the abrasive wheel towards the article being worked.
- the working zone of the device lying in front of the abrasive wheel and extending in the direction of travel of the carrying member is thus not restricted in any way.
- FIG. 1 shows the device for dressing abrasive wheels, as
- FIG. 2 shows the same in section taken along the line ll-ll in FIG. I.
- the device shown in the drawings comprises a supporting member 1 (FIGS. 1 and 2) with a flat guideway 2 inclined at an angle 45 to the horizon, a member 4 carrying an abrasive wheel 3, said member being slidable along the supporting member I, and a holder 5 on which a dressing tool 6 is fixed.
- the holder Sis mounted on the supporting member I with a possibility of travelling along its inclined flat guideway 2 on rollers 7, and is associated with the carrying member 4 by means of a guiding projection 8 of a dovetail shape received in a congruent recess 9 in the body of the holder 5.
- the guiding projection 8 is disposed at an angle B: 45 to the flat guideway 2, that is, perpendicular to the horizon.
- a disk saw 10 (FIGS. 1 and 2) is positioned into a clamping means lll, the abrasive wheel 3 is brought to the teeth 12 of the saw, and their grinding is effected.
- the abrasive wheel 3 gradually wears out.
- the dressing tool 6 with the holder 5 is fed to the abrasive wheel 3.
- the holder 5 slides down the inclined flat guideway 2 on the rollers 7. While thus descending, the holder 5 through the intermediary of the vertical guiding projection 8 and recess 9 interacts with the member 4 carrying the abrasive wheel 3, causing said member 4 to move towards the disk saw 10 being worked.
- the value a of feeding the abrasive wheel is equal to the thickness b of the layer of abrasive material removed by the dressing tool 6.
- the working zone of the present device is not restricted in any way, so that large-sized articles of any shape can be disposed within it for working.
- a device for dressing an abrasive wheel in the course of its rotation when working an article within a predetermined working zone comprising: a supporting member; inclined guides provided on said supporting member at an angle of 45to the horizontal; a member carrying said abrasive wheel and mounted on said supporting member between said inclined guides and said article being worked and adapted for movement towards the latter; vertical guides provided on said abrasive wheel-carrying member on the side opposite to said article being worked; a holder provided on said supporting member adapted to be slid along said inclined and vertical guides; a dressing tool secured on said holder, and adapted to effect a follow-up motion in a direction perpendicular to that of said abrasive wheel; said supporting member and holder being arranged so as to encompass said abrasive wheel-carrying member on the side opposite to the location of said article being worked thereby leaving the working zone unrestricted.
