Press fitting device for crankshaft gears

Abstract

The invention discloses a press fitting device for crankshaft gears. The press fitting device comprises a lathe bed, a plurality of clamps, gear press-fitting mechanisms and crankshaft transferring mechanisms, wherein the clamps are arranged on the lathe bed and are used for installing workpieces on press fitting stations, the gear press-fitting mechanisms are arranged on the lathe bed and are used for carrying out press fitting on the corresponding gears on the workpieces on the corresponding press-fitting stations, and the crankshaft transferring mechanisms are arranged on the lathe bed andare used for sequentially installing the workpieces on the clamps according to a preset process sequence. The press fitting device for the crankshaft gears has the advantages that all the workpieces can be arranged on the different press fitting stations through the multiple clamps, the circulation of all the workpieces among the different press-fitting stations can be realized through the crankshaft transferring mechanisms, meanwhile, press fitting of the corresponding gears of the workpieces on all the press fitting stations can be realized through the gear press-fitting mechanisms, and therefore press fitting of all the gears on the workpieces (crankshafts) can be rapidly and efficiently realized, the manual labor can be greatly reduced, and the process flow can be shortened.

Description

technical field [0001] The invention relates to the technical field of mechanical design, in particular to a crank gear pressing device. Background technique [0002] The crankshaft of a motorcycle engine needs to be pressed with various gears in order to transmit power. Each gear is divided into main drive gear, balance shaft drive gear, and valve drive gear according to their different functions. Accurate angles are required during operation to meet power transmission, stable crankshaft operation, and accurate valve opening and closing. The angle is accurate and the deviation is small. [0003] In the prior art, the conventional crankshaft gear press-fitting method is to press-fit each gear onto a pressure sleeve first, and then separately press-fit through the pressure sleeve using a single-axis vertical hydraulic press. However, when installing in this way, the clamping process of each gear needs to be replaced. The labor intensity is high, the process is cumbersome, a...

Problems solved by technology

However, when installing in this way, the clamping process of each gear needs to be replaced. The labor intensity is high, the process is cumbersome, and the efficiency is low. In addition, in the prior art, it is generally divided into three equipments for press-fitting respectively, and each device press-fits a gear , so it takes up a lot of manual labor, which is easy to cause waste of manpower and material resources. At the same time, due to the heavy weight of the crankshaft, it is more laborious to carry
