[0002] Diamond rollers are dressing tools for mass grinding and forming, and are generally used to dress grinding wheels. Diamond roller dressing devices consist of diamond rollers and fixtures. Traditional diamond roller dressing fixtures consist of clamping rods and rotating shafts. The diamond roller is fixed to the outer wall of the rotating shaft, and two clamping rods are used to clamp the two ends of the rotating shaft, and the two clamping rods are driven to rotate by a driving device. In order to adapt to diamond rollers of different sizes, the ends of the clamping rods are conical in shape. However, the conical shape of the clamping rod ends leads to low clamping force and insufficient clamping stability, which affects the processing accuracy to a certain extent and brings inconvenience to users. In order to solve the shortcomings of the existing technology, we propose a diamond roller dressing fixture. Utility Model Content

[0023] The circular table frame 53 is pushed by the electric push rod 52, and the square through hole 56 limits the moving direction of the clamping block 55. At this time, the clamping block 55 will move along the direction of the slide groove 54 relative to the circular table frame 53. Since the circular table frame 53 is in the shape of a truncated cone, it will push the clamping block 55 along the square through hole 56 away from the central axis of the clamping tube 51.

At the same time, the top protrusions of the multiple clamping blocks 55 can further accurately limit the rotating shaft 3. Start the motor 65 to drive the bidirectional screw 66 to rotate. At this time, the two brackets 64 will move toward the middle or disperse to the left and right sides along the direction of the multiple cylindrical rods 63, and drive the two clamping tubes 51 and the two driving devices 2 to move synchronously to achieve the centering clamping of the rotating shaft 3.
