Abstract
A belt processing device moves a processing belt relative to a workpiece to process the workpiece. The belt processing device comprises a first roller that is a processing roller, a second roller that is a driven roller, a processing belt that is supported by the first roller and the second roller, a pneumatic motor that rotates the first roller or the second roller, an elastic ring that is installed on the outer circumference of the first roller, and an expansion prevention member that is installed on the elastic ring and has a greater modulus of elasticity than the elastic ring.
Claims6
A rotary table which rotates a workpiece mounted on a table or pallet by rotating the table or pallet, the rotary table comprising:
- a housing including a cylindrical holding part extending along a first axis direction,
- a rotary member comprising a flange part, which is formed along an outer periphery thereof, and which rotates about the first axis with respect to the holding part together with the table or the pallet arranged on the front side in the first axis direction,
- a roller bearing which is arranged in the housing and which rotatably supports the rotary member,
- a motor which drives the rotation of the rotary member, and
- a support member which is arranged in the housing on the rear side of the flange part in the first axis direction, which has a sliding surface at a front end thereof in the first axis direction, and which is configured to be movable forward and rearward along the first axis direction, wherein the sliding surface contacts the flange part when the support member is advanced and separates from the flange part when it is retracted.
