It is mainly used to eliminate deformation after heat treatment and improve gear accuracy, and to grind the tooth edge of the saw blade so that the performance of the saw blade can be repaired to a certain extent. The emergence of gear grinding machines has improved the performance of saw blades to a certain extent.

The annular placement opening 2 is designed to facilitate the placement of the annular band saw blade. The two ends of the annular band saw blade are fixed through the sliding opening 7 by the fixing plates 6 arranged at both ends of the driving mechanism and the sliding support mechanism. The gear grinder 11 arranged at one end of the support plate 10 is retracted by the second electric push rod 8 to grind the teeth corresponding to the position of one end of the annular band saw blade. After one tooth is ground, the second electric push rod 8 is raised and then rotated by the first motor 9 to grind the next tooth.

It is convenient to manually remove the annular band saw blade when it is separated from the annular placement opening 2, thereby solving the problem that the annular band saw blade may be tilted or offset when moving after grinding, resulting in the gear grinder and the tooth angle not corresponding to each other, which will cause unnecessary damage to the annular band saw blade.

[0025] In order to drive the fixing plates 6 at both ends to fix the annular band saw blade, Figure 2 and 3 As shown, the driving mechanism includes a bidirectional screw 12, a second motor 13, a driving gear 14, a driven gear 15 and a threaded sleeve 16. The bidirectional screw 12 is rotatably connected to one end of the top cavity of the grinding table 1, and the second motor 13 is fixedly connected to the other end of the top cavity of the grinding table 1. The spindle of the second motor 13 is fixedly connected to the driving gear 14, and the rod wall of the bidirectional screw 12 is fixedly connected to the driven gear 15.

[0030] Working principle:

[0031] During use, the annular band saw blade is placed in the annular placement opening 2 opened on the top of the grinding table 1, and the two ends of the annular band saw blade are fixed through the sliding opening 7 by the fixing plates 6 arranged at both ends of the driving mechanism and the sliding support mechanism, and the gear grinder 11 arranged at one end of the support plate 10 is retracted by the second electric push rod 8 to grind the teeth with one end of the annular band saw blade. After one tooth is ground, the second electric push rod 8 rises and is rotated by the first motor 9 to grind the next tooth. After grinding, the unloading ring 5 arranged on the top of the connecting plate 4 is used, and the annular band saw blade is pushed upward by the extension and contraction of the first electric push rod 3 to disengage from the annular placement opening 2 for manual removal of the annular band saw blade. The annular band saw blade is fixed and the gear grinder 11 is moved, thereby solving the problem that the annular band saw blade may be tilted or offset when moving after grinding, resulting in the gear grinder and the tooth angle not corresponding to each other, which will cause unnecessary damage to the annular band saw blade.
