By setting the negative pressure pretreatment process of the tooth blank, accurate visual inspection of the tooth blank before processing is facilitated and the influence of dirt on the surface of the tooth blank on the visual inspection result is reduced;

[0052] At the same time, by setting the visual acquisition probe 6, the end face of the tooth blank can be visually imaged and inspected before the tooth blank is processed, and then the quality of the tooth blank can be judged by visual inspection;

[0053] A back frame 7 is connected to the frame 1. A linear drive module 8 is installed on the back frame 7. A tool holder 9 is connected to the linear drive module 8.

A fixed-point transmission module adapted to the hobbing cutter 30 is installed on the tool holder 9.

[0054] By setting the linear drive module 8, the relative distance between the hob 30 and the gear blank is changed, thereby changing the feed speed of the hob 30 and the hobbing strength and hobbing efficiency of the gear blank;

[0055] The hob 30 includes a cutter shaft rotatably connected to the hob frame 11, the axis of the cutter shaft is parallel to the rotation axis of the hob frame 11, the axis of the cutter shaft is perpendicular to the axis of the support shaft 13, a cutter head is mounted on the cutter shaft, and a driven gear 31 is mounted on the cutter shaft;

[0056] An oil box 12, on which a support shaft 13 linked to a fixed-point transmission module is rotatably connected, and a support platform 14 is mounted on the support shaft 13;

[0057] The fixed-point transmission module includes a sliding shaft 32 rotatably connected to the back frame 7 and driven by a third motor, a differential shaft 33 rotatably connected to the hobbing frame 11, a fixed transmission shaft 34 and a shaft sleeve 35. The differential shaft 33 is connected to the fixed transmission shaft 34 through a chain belt, and a driving gear 36 adapted to be connected to the driven gear 31 is installed on the fixed transmission shaft 34.

[0058] When a certain hob cutter 30 moves to a position facing the support shaft 13, the driven gear 31 in the hob cutter 30 is connected to the driving gear 36 and drives the cutter shaft in the hob cutter 30 to rotate;

[0059] When the hob 30 is not facing the support shaft 13, the driving gear 36 is not connected to the driven gear 31, and the cutter shaft loses the transmission function.

[0060] The shaft sleeve 35 and the differential shaft 33 are both equipped with first bevel gears, and the two first bevel gears mesh with each other. The sliding shaft 32 and the supporting shaft 13 are both equipped with second bevel gears, and the two second bevel gears mesh with each other. The shaft sleeve 35 is internally provided with a coupling groove with both ends opened and slidably connected to the sliding shaft 32. The cross sections of the coupling groove and the sliding shaft 32 are both regular polygons.

[0061] Three-dimensional detection mechanism, used for three-dimensional imaging detection of formed workpieces;

[0062] The three-dimensional detection mechanism includes a first depth camera 37 installed on the material transfer platform 2 and used for three-dimensional scanning of the gear blank, and a second depth camera 38 installed on the oil box 12 and arranged opposite the support shaft 13.

[0064] During gear hobbing operation, the pump oil nozzle 41 discharges liquid at a set flow rate, thereby achieving cooling of the gear blank and carrying out of waste materials;

[0065] The working principle of the present invention is as follows: during operation, the positioning protrusion 17 is set so that the gear blank and the formed workpiece are effectively positioned and conveyed during the feeding and conveying of the gear blank and the unloading and conveying of the formed workpiece. When the gear blank is conveyed, the negative pressure vacuum cleaner 23 continuously generates negative pressure and performs vacuuming on the gear blank. By setting the negative pressure pretreatment process of the gear blank, accurate visual inspection of the gear blank before processing is facilitated and the influence of dirt on the surface of the gear blank on the visual inspection result is reduced. When the gear blank needs to be loaded, the visual acquisition probe 6 is set so that the pressing shaft 4 is coaxially arranged with the gear blank to be loaded. After the pressing shaft 4 is coaxially arranged with the gear blank to be loaded, the visual acquisition probe 6 performs visual imaging of the end face of the gear blank to be processed, and judges the quality of the gear blank to be processed by visual inspection. Subsequently, the pressing shaft 4 penetrates into the axial hole on the gear blank, and the pneumatic clamp clamps the gear blank. After the pneumatic clamp clamps the gear blank, the pressing shaft 4 drives the gear blank to generate a set speed. The first depth camera 37 performs three-dimensional scanning and modeling on the surface of the gear blank to be processed, and then determines the quality of the gear blank to be processed by a three-dimensional imaging detection method. When the gear blank to be processed is not a good product, the detection host 39 automatically alarms. After the pre-detection is completed, the pressing shaft 4 drives the gear blank to move to the support table 14. Then, the pressing shaft 4 rotates at the same speed as the gear blank, and the hob 30 of the specified specification processes the gear blank. When the gear blank is processed, the pump oil nozzle 41 discharges liquid at a set flow rate, thereby achieving cooling of the gear blank and removing of waste materials. After the gear blank is processed, the second depth camera 38 performs a second three-dimensional scanning and modeling on the formed workpiece, and determines the quality of the formed workpiece by a three-dimensional imaging detection method. After the quality detection is completed, the visual acquisition probe 6 performs a second imaging detection on the end face of the formed workpiece, and determines the specification parameters of the gear rolling. After the quality detection is completed, the formed workpiece is transferred to the conveyor belt 15 for unloading.
