Embodiment Construction
[0006] An eight-tooth groove processing technology, which can be processed with a single tooth or with a four-tooth integrally formed tool. Single-tooth processing is adopted, and the forming tool is processed by a 35°diamond-shaped single-tooth blade. Firstly, the tooth groove is roughly shaped, and then each tooth groove is finely machined on both sides of the groove. The four-tooth integral forming tool is used for processing, and the two sides are processed separately. After processing, the consistency of the inter-rod spacing of the tooth groove obtained after processing is not greater than 0.03mm, the profile is not greater than 0.4mm, and the coaxiality is not greater than 0.05mm relative to the inner hole reference.

The invention discloses a machining technology for eight-tooth grooves. According to the technology, single-tooth machining can be adopted, and four-tooth integrally forming tool machining can also be adopted. When single-tooth machining is adopted, a 35-degree diamond single-tooth blade is adopted as a forming tool for machining, the tooth grooves are inserted roughly, and then the two sides of each tooth groove are precisely machined. When four-tooth integrally forming tool machining is adopted, the two sides are machined respectively, the cross-rod distance consistency of the machined tooth grooves is not larger than 0.03 mm, the profile tolerance is not larger than 0.4 mm, and coaxiality is not larger than 0.05 mm relative to the inner hole benchmark. By the adoption of the above technology, machined parts are good in size stability, the machining time is short, size stability and consistency are high, and the machining efficiency is greatly improved.
Description
technical field [0001] The invention relates to a processing technique for eight tooth grooves. Background technique [0002] In industrial production, mechanical equipment is widely used, and the accuracy of the tooth groove of the gear is required to be high. There are many ways to process the tooth groove of the gear on the market, but it is mainly limited to the direct processing method of the forming tool. For the processing method of eight tooth grooves, single-tooth processing is generally used. The consistency of the tooth grooves processed by this processing method across the bar is difficult to ensure. At the same time, each tooth groove must be processed separately. , High defective rate. Herein, the processing technology of the eight tooth slots uses the forming tool to process the four tooth slots at the same time, and the two sides are processed separately, without rough insertion, and the forming tool is directly used for one-time processing and forming. The ...
