Description

Technical Field

[0001] This utility model relates to the field of hard shaft machining technology, specifically a straightening machine for hard shaft machining. Background Technology

[0002] In numerous fields such as machinery manufacturing, automotive industry, and aerospace, rigid shafts are widely used as crucial components for transmitting power and motion. In automotive engines, the crankshaft, as a core rigid shaft component, directly affects the engine's power output and stability in terms of its precision and straightness.

[0003] The prior art discloses an automatic straightening machine for processing shaft parts, with publication number CN118989050B. The machine includes a support platform with vertical support plates fixed to the upper ends of both sides. An electric slide table is fixed to the middle of the upper end of each of the two sets of vertical support plates, and a lifting module is slidably connected to the front end of the electric slide table. A pressing block is fixedly connected to the lower end of the lifting module. Lifting support modules are symmetrically installed on both sides of the upper end of the support platform. This automatic straightening machine for processing shaft parts, by incorporating a loading and unloading mechanism, can actively load and unload shaft parts after inspection, improving operational convenience and minimizing external damage to the shaft parts during the loading and unloading process.

[0004] The aforementioned straightening machine for machining hard shafts has a linkage between its loading / unloading mechanism and transmission mechanism. This linkage allows for synchronous adjustment of the positions of the transmission rod and transmission rollers during loading / unloading to prevent obstruction of the shaft parts and improve operational convenience. However, the aforementioned straightening machine for machining hard shafts cannot adjust the straightening position during straightening and requires pushing the hard shaft. The accuracy of manually pushing the hard shaft is not as good as that of the lever adjustment mechanism, resulting in poor performance during use. This needs to be improved. Utility Model Content
