Assembly system and assembly method for press-mounted bushing

Abstract

The invention discloses an assembly system and an assembly method for a press-mounted bushing. The assembly system comprises a mounting machine board and an assembly device, wherein an engine body is fixed on the mounting machine board; the assembly device is fixed on the mounting machine board and comprises an automatic press-mounted device; the automatic press-mounted device comprises a first servo press-mounted device provided with a first pressing head guiding device and a second servo press-mounted device provided with a second pressing head guiding device; the first pressing head guiding device and the second pressing head guiding device are oppositely arranged on two sides of the engine body. The assembly method comprises the steps of firstly, mounting bushings on the second pressing head guiding device and the first pressing head guiding device; secondly, transferring the bushing on the second pressing head guiding device and the bushing on the first pressing head guiding device to the inside of the engine body by press mounting. According to the assembly system and the assembly method which are disclosed by the invention, automatic guide press mounting is realized; high assembly efficiency and high assembly precision are obtained; besides, accurate and effective control over the mounting phase and depth is realized.

Description

technical field [0001] The invention relates to an assembly system, in particular to an assembly system for press-fitting a bush, and an assembly method thereof. Background technique [0002] In the field of engine manufacturing, especially in the manufacture of medium and heavy-duty engines, due to the particularity of the structure of the engine body and the camshaft, there is no widely applicable camshaft bushing assembly device and method. Usually, the operator uses some auxiliary devices to cooperate with each other to complete the assembly. , resulting in obvious shortcomings in the installation of camshaft bushings: 1. The installation efficiency of camshaft bushings is low, and the installation process lacks automatic guiding and pressing devices; 2. The installation accuracy of camshaft bushings is poor, and the installation phase and depth lack limit devices ; 3. The production cost of the camshaft bushing is high, and there are many reworks caused by unqualified b...
