Description

Technical Field

[0001] This utility model relates to the field of gear processing technology, and in particular to an auxiliary positioning device for a milling machine used in gear production. Background Technology

[0002] In the gear manufacturing process, the gear milling machine is the core equipment for machining gear teeth, and the positioning accuracy of the gear blank directly determines key indicators such as the pitch error and tooth profile accuracy of the final gear product. Currently, the commonly used positioning methods for gear milling machines mostly adopt a single center positioning or chuck clamping structure, which have problems such as poor positioning stability, difficulty in adjustment, and low adaptability.

[0003] The prior art can be referenced in Chinese Patent No. CN218168951U, which discloses an auxiliary positioning device for a milling machine used in gear production. The device includes a base, a U-shaped frame fixedly mounted on the top of the base, a hydraulic cylinder on one side of the U-shaped frame, and a driven rod fixedly mounted on the output shaft of the hydraulic cylinder. The driven rod is slidably mounted on the U-shaped frame. However, when machining and fixing gears with shafts, the clamping force cannot be kept stable. Excessive clamping can easily cause deformation of the blank, while insufficient clamping force can cause the blank to shift during the machining process. Therefore, an auxiliary positioning device for a milling machine used in gear production is now provided. Utility Model Content

The controller adjusts the first hydraulic push rod according to a preset value to ensure a constant clamping force, avoid over-clamping that could deform the workpiece or insufficient clamping force that could cause offset, improve positioning accuracy, and overcome the shortcomings of existing technologies.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An auxiliary positioning device for a gear milling machine in gear production includes a base plate.
