Device for improving quality of gear-by-gear heating ends through guide blocks

The invention discloses a device for improving the quality of gear-by-gear heating ends through guide blocks. The device comprises a retainer, an upper pressing mechanism, the upper guide block, an upper clamping mechanism, an upper fixing frame, an upper adjusting mechanism, a lower pressing mechanism, the lower guide block, a lower clamping mechanism, a lower fixing frame and a lower adjusting mechanism. Structures partially stretching out are arranged at the upper end and the lower end of the retainer, and the structures are connected with the upper fixing frame and the lower fixing frame.The fixed ends of the upper clamping mechanism and the lower pressing mechanism are connected with the upper fixing frame and the lower fixing frame, the telescopic ends of the upper clamping mechanism and the lower pressing mechanism are connected with the upper guide block and the lower guide block, and same tooth profile contours are arranged on the surfaces of the upper guide block, the lowerguide block and heated gea
