Integrated overturning roller bed

Abstract

The present invention is applicable to the field of engine assembly lines, and provides an integrated overturning roller table. The integrated overturning roller table includes: a bracket, a rotating mechanism, a roller table mechanism, a jacking mechanism and an integrated positioning fixture. The rotating mechanism is arranged on the On the bracket, the roller mechanism is arranged on the rotating mechanism, the jacking mechanism is arranged between the roller mechanism and fixed on the rotating mechanism, and the integrated positioning fixture is arranged on the roller Above the road mechanism and connected to the rotating mechanism, the invention reduces the equipment cost through structural improvement; integrates the rotating mechanism, the roller table mechanism and the integrated positioning fixture, and integrates the jacking mechanism on the roller table mechanism , which greatly shortens the jacking distance and improves the production efficiency of the workshop; in addition, the turning angle can be less than 90 degrees, which meets the demand for large-angle turning and expands the scope of application. Low, press fit rate increased to over 95%.

Description

technical field [0001] The invention belongs to the field of engine assembly lines, in particular to an integrated overturning roller table. Background technique [0002] The assembly of the three-slot valve lock clamp on the engine cylinder head requires lifting and turning the engine cylinder head. Due to the precise cooperation between the lock clamp and the valve, the equipment requires high press-fitting accuracy. The existing equipment realizes the function by designing a jacking and turning mechanism under the roller table. The jacking mechanism first lifts the tray together with the cylinder head and leaves the roller table, and the turning mechanism drives it to turn over to the rated angle. In actual operation, the lifting distance of the jacking mechanism is long, and the overall cycle time of the equipment is long. Since the jacking and flipping structure is designed separately from the main body of the press-fitting equipment, and has no specific mechanical con...

Problems solved by technology

[0003] The purpose of the present invention is to provide an integrated overturning roller table, which aims to solve the problem in the prior art that only a jacking and overturning mechanism is designed under the roller table to realize the overturning function. The turning structure is designed separately from the main body of the press-fitting equipment. The jacking and turning mechanism needs a long lifting distance, which leads to a longer overall cycle time of the equipment and reduces the efficiency of the field. The assembly accuracy is greatly affected by the technical level of the assembler, and the pass rate is low. , difficult to debug
