Embodiment Construction
[0015] Such as figure 1 Among them, a two-way automatic tool conversion mechanism for a gear shaping machine includes a machine base 16, the tool holder body 4 is hinged to the machine base 16 through a pin shaft 12, and the tool holder rod 14 is installed in the tool holder body 4 so as to be slidable in the axial direction , the slide of the knife holder rod 14 is guided by the guide part 13 .
[0016] The slider crank mechanism 3 is hinged with the slider bar 14, that is, the rotation of the crank drives the linear motion of the slider bar 14, and the transmission shaft 17 driven by the driving device is connected with the slider slider mechanism 3, specifically, the motor 15 passes through The first synchronous belt 1 drives the transmission shaft 17 to rotate. One side of the knife rest body 4 is provided with a knife letting roller 5, and the other side of the knife rest body 4 is provided with a spring damper 6;
[0017] The transmission shaft 17 is connected with the...

A two-way automatic tool transfer mechanism for a gear shaping machine, including a machine base, the tool holder body is hinged to the machine base through a pin shaft, the tool holder rod is installed in the tool holder body in an axially slidable manner, and the crank slider mechanism and the tool holder rod Hinged, the transmission shaft driven by the driving device is connected with the crank slider mechanism, the knife rest roller is provided on one side of the tool holder body, and the spring damping is provided on the other side of the tool holder body; the transmission shaft is connected with the transfer mechanism through the transmission mechanism The cutter shaft is connected, and the first cutter cam and the second cutter cam that are used to cooperate with the cutter roller can be slidably installed on the cutter shaft in the axial direction, and the first cutter cam and the second cutter cam follow the Let the rotation of the knife shaft rotate, and the first knife letting cam and the second knife letting cam are connected with the switching cylinder that drives their slides. The present invention realizes the automatic conversion of the inner and outer teeth during gear shaping by adopting the switching cylinder to switch the first knife-releasing cam and the second knife-releasing cam matched with the knife-releasing roller. Very easy to realize automatic control.
Description
technical field [0001] The invention relates to a part of a gear shaping machine, in particular to a bidirectional automatic conversion mechanism for a gear shaping machine which utilizes double cams to automatically realize the inner and outer gears on the gear shaping machine. Background technique [0002] According to the requirements of the gear shaping machine for processing gears, the gear shaping cutter needs to move away from the workpiece during the return stroke, so as to avoid blunting the gear shaping blade and scratching the processed workpiece surface during the return stroke. Due to the opposite direction of tool clearance required when machining internal and external gears, the conversion of tool clearance when machining internal and external gears by gear shaping machines has become a technical problem. The existing knife clearance mechanism is complex and costly, and manual work is required for the conversion Adjustment is very inconvenient. [0003] Chine...
