Description

Technical Field

[0001] This utility model relates to the field of gear hobbing machine gear setting technology, and more specifically, to a gear hobbing machine gear setting mechanism. Background Technology

[0002] CNC gear hobbing machines are suitable for batch, small batch, and single-piece production of cylindrical gears and worm gears, as well as drum gears with certain parameters. In practical applications, CNC gear hobbing machines require a gear setting device for secondary processing of the workpiece. For example, the gear setting device for a CNC gear hobbing machine disclosed in patent CN217529500U has a mounting plate fixed to the column of the CNC gear hobbing machine by bolts. The cylinder mounting table can slide on the surface of the slide block and is fixed in position by locking screws. The telescopic rod at the output end of the dual-axis cylinder drives the slide plate to move back and forth inside the slide sleeve. The induction probe installed on the end face of the slide plate moves quickly to the detection position. The worktable rotates the workpiece, and the induction probe detects the tooth surface, completing the gear setting. The induction probe can move back and forth through the dual-axis cylinder, enabling the CNC gear hobbing machine in this case to perform secondary processing on a wider variety of workpieces, avoiding the need to repeatedly move the gear setting device for some workpieces, thereby saving time and effort and improving processing efficiency.

[0003] When the above-mentioned device is working, the sensing probe moves quickly into position through the cylinder, the probe detects the tooth surface of the workpiece, and the workpiece is rotated to the correct position in combination with the rotation of the workpiece table, so as to realize automatic tooth setting operation quickly and accurately. However, the cylinder mounting table is prone to offset on the outer end face of the slide, which affects the efficiency and stability of tooth setting of the gear hobbing machine.
