Abstract
Abstract A dressing device for dressing the peripheral surface of a grinding wheel mounted within a grinding machine comprising a compensating ram and profile ram coaxially aligned with each other within a main body which is fixedly mounted upon a traverse table. The compensating ram is adjustably movable by means of a compensating device mounted upon the profile ram and the profile ram is slidably movable toward the grinding wheel by an actuator mounted within the main body. Therefore, the rigidity of the dressing device is increased so as to thereby obtain better dressing performance and accuracy.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
219 words
A device for dressing a peripheral surface of a grinding wheel mounted upon a grinding machine, comprising: a supporting base; a feeding table slidably mounted upon said supporting base so as to be movable toward and away from said grinding wheel by means of a table feeding device; a template member fixedly mounted on said feeding table and having a profile face thereon; a traverse table slidably movable upon said feeding table by suitable drive means in a direction parallel to the axis of said grinding wheel; a main body fixedly mounted upon said traverse table; a compensating ram means slidably mounted within said main body and provided with a dressing tool for dressing the outer periphery of said grinding wheel; a profile ram means slidably disposed in tandem relationship to said compensating ram means within said main body; a stylus fixedly attached to one end of said profile ram for engageable co-operation with said template member; actuating means provided within said main body and integrally associated with said profile ram means for moving said profile ram means together with said compensating ram means toward said grinding wheel to thereby urge said stylus to contact said template member; and feeding means operatively connected with said compensating ram for compensating the position of the same relative to said profile ram.
Claim 2
Independent Claim
219 words
A device for dressing a peripheral surface of a grinding wheel mounted upon a grinding machine, comprising: a supporting base; a feeding table slidably mounted upon said supporting base so as to be movable toward and away from said grinding wheel by means of a table feeding device; a template member fixedly mounted on said feeding table and having a profile face thereon; a traverse table slidably movable upon said feeding table by suitable drive means in a direction parallel to the axis of said grinding wheel; a main body fixedly mounted upon said traverse table; a compensating ram means slidably mounted within said main body and provided with a dressing tool for dressing the outer periphery of said grinding wheel; a profile ram means slidably disposed in tandem relationship to said compensating ram means within said main body; a stylus fixedly attached to one end of said profile ram for engageable co-operation with said template member; actuating means provided within said main body and integrally associated with said profile ram means for moving said profile ram means together with said compensating ram means toward said grinding wheel to thereby urge said stylus to contact said template member; and feeding means operatively connected with said compensating ram for compensating the position of the same relative to said profile ram.
Claim 3
Dependent Claim
77 words
A device as set forth in claim 1, wherein said feeding means comprises: a rotating shaft member rotatably mounted within said profile ram means and having a threaded portion which is threadably connected with said compensating ram means for moving said dressing tool by a desired distance toward said grinding wheel; a compEnsating device fixedly mounted upon said profile ram means and operably connected with said rotating shaft member for compensating the position of said dressing tool.
Claim 4
Dependent Claim
79 words
A device as set forth in claim 2, wherein said compensating device comprises: a main body; connecting means provided within said last-mentioned main body of said compensating device operably connected with said rotating shaft member; a worm wheel member integrally secured to said connecting means; and drive shaft means rotatably journaled within said last-mentioned main body of said compensating device and provided with a worm member which is engaged with said worm wheel for rotating said rotating shaft member.
Claim 5
Dependent Claim
67 words
A device as set forth in claim 2, wherein said actuating means comprises: a hydraulic cylinder provided within said main body; a piston member slidably mounted within said hydraulic cylinder; and connecting rod means extending from said piston member and fixedly secured to said profile ram means at one end thereof so as to thereby move said profile ram means toward and away from said grinding wheel.
