Description

Technical Field

[0001] The utility model relates to the technical field of diamond rollers, in particular to a diamond inlay positioning fixture for a diamond roller. Background Art

[0002] The diamond roller is a high-efficiency, high-life, low-cost grinding wheel dressing tool used for special machine tools and gear grinders for large-scale shaping grinding. Diamond particles are evenly arranged on its surface. During the production and processing of the diamond roller, a clamp is used to clamp the diamond to the embedding position and position it at the same time, and then the diamond is squeezed onto the diamond roller body for embedding. There are existing diamond embedding positioning clamps. The existing clamps generally clamp the diamond with pneumatic fingers. The structure is simple and the cost is low. However, the pneumatic fingers lack a locking structure when clamping. When the force of the clamp is large, it is not conducive to the ejection and embedding of the diamond. When the clamping force is small, during the ejection of the diamond, the diamond is prone to flipping when the force is unbalanced, which will stretch the clamp open and cause the dislocation of the diamond, affecting the production quality of the diamond roller.
