Description

Technical Field

[0001] The utility model relates to the technical field of band saw blade grinding, in particular to a hob grinder for band saw blade processing. Background Art

[0002] A hob grinder is a specialized machine tool used to sharpen hobs. Using a grinding wheel or other abrasive material, the hob is precisely ground to the desired geometric shape and dimensional accuracy. In band saw blade manufacturing, a hob grinder is used to regrind the hob to restore its sharpness and cutting performance, thereby ensuring cutting quality and efficiency. A hob grinder typically consists of a machine bed, a worktable, a grinding wheel head, a drive system, and a control system. The hob to be ground is mounted on the worktable, and the drive system drives the grinding wheel to rotate, precisely grinding the hob.

[0003] Existing grinder fixtures commonly include an thimble clamp and a tailstock that clamp the band saw blade by approaching each other, and then the angle of the band saw blade is adjusted by the tailstock. Then the worker pushes the grinding table back and forth to grind the band saw blade. Although this clamping method has a simple structure, in order to support band saw blades of different diameters, the contact area between the thimble and the band saw blade is generally very small, which causes the band saw blade to easily deviate during the grinding process, affecting the grinding effect. In addition, the worker's behavior of pushing the grinding table back and forth is also very physically demanding. Utility Model Content
