US 5,117,588 A · Semi-automatic dressing accessory

Abstract

A dresser apparatus for dressing a grinding wheel to a desired cross sectional shape, the apparatus including a dresser frame connected to a stationary dresser base, and a slider block slidably connected to the dresser frame. A follower frame is mounted to the slider block for sliding movement with respect to the slider block in a second, substantially vertical direction. Linear actuator means are disclosed for causing the slider block to slide in the first direction with respect to the dresser frame. A cam is provided, corresponding to the desired shape of the grinding wheel, and a cam follower is attached to the follower frame and postioned thereon so as to bear on the cam surface. In one embodiment the cam follower causes the follower frame to move in the second direction according to the shape of the cam surface while the linear actuator means moves the slider block in the first direction. In another embodiment, directed to dressing wheels with a flat or reverse angled surface, a second linear actuator provides the vertical movement. A grinding wheel dressing tool is affixed to the dresser arm and positioned so as to bear on and dress the grinding wheel in conformity with the shape of the cam surface. The dressing tool is attached to the dresser arm, and the cam follower to the follower frame, at an oblique angle with respect to the grinding wheel axis.

Dependent claims

A dresser apparatus for dressing a grinding wheel to a desired cross sectional shape, which grinding wheel is caused to continuously rotate about an axis with respect to a drill pointer base by prime mover means, said dresser comprising:

a dresser base affixed substantially immovable with respect to said drill pointer base;
a dresser frame connected to said dresser base;
a follower carriage slidably connected to said dresser frame so as to permit movement of said follower carriage with respect to said dresser frame substantially linearly along a first path substantially radial to said axis and also substantially linearly along a second path substantially parallel to said axis;
first linear actuator means for causing said follower carriage to slide along said first path;
a cam attached to said dresser frame, having a cam surface corresponding to the desired shape of the grinding wheel;
a cam follower attached to said follower carriage and positioned thereon so as to bear on said cam surface of said cam;
second linear actuator means for causing said follower carriage to slide along said second path, thereby causing said follower carriage to move along said first and second paths according to the shape of said cam surface;
and
a grinding wheel dressing tool carried by said follower carriage and positioned so as to bear on and dress said grinding wheel in conformity with the shape of said cam surface.
