Automatic hot-pressing assembly device of balancing shaft and helical gear

Abstract

The invention discloses an automatic hot-pressing assembly device of a balancing shaft and a helical gear, comprising a dynamic balancing machine (2), a gear hot-pressing machine (3), a manipulator (4) and a feeding and blanking station (5), wherein the manipulator (4) clamps a balancing shaft to be assembled and a helical gear to be assembled on the feeding and blanking station (5) and respectively sends the balancing shaft to be assembled and the helical gear to be assembled to the dynamic balancing machine (2) and the gear hot-pressing machine (3), the dynamic balancing machine (2) measures the dynamic unbalance quantity of the balancing shaft and carries out direction alignment on the balancing shaft, the helical gear is heated in the gear hot-pressing machine (3), and the balancing shaft subjected to dynamic unbalance measurement and direction alignment is sent into the gear hot-pressing machine (3) through the manipulator (4) and is in hot-pressing assembly with the heated helical gear. The device has sufficient static, dynamic and heat stable rigidity and accuracy; the whole system has good dynamic performance; and an execution element which is selected for a detection measurement and display system has the advantages of high accuracy, good reliability, strong anti-interference ability, high response speed and stable continuous processing performance.

Description

technical field [0001] The invention relates to the center of gravity alignment of a gearbox balance shaft and the field of hot pressing assembly of the balance shaft and the helical gear, in particular to an assembly device of the balance shaft and the helical gear of an automobile gearbox. Background technique [0002] The balance shaft of the automobile gearbox plays the role of balancing and reducing noise. The balance shaft is designed into an unbalanced crankshaft structure according to the overall unbalance of the moving parts of the gearbox, so as to balance the overall unbalance of the moving parts of the gearbox. The assembly accuracy of the balance shaft and the helical gear directly affects the balance effect of the balance shaft. The position of the unbalanced center of gravity of the balance shaft and the starting position of the helical angle of the helical gear are required to meet the required accuracy of engineering design. The center of gravity of the ba...

AI Technical Summary

Problems solved by technology

At present, the assembly of domestic balance shafts and helical gears is first carried out on the dynamic balancing machine to align and mark the center of gravity, and then use simple tooling to assemble by manual hot pressing, which has low efficiency, low assembly accuracy, and high scrap rate.

The prior art does not relate to the automatic heat-pressing device of the balance shaft helical gear
