On-line type turnover mechanism for hub

Abstract

An on-line type turnover mechanism for a hub comprises a supporting frame, a clamping turnover structure and a stroke compensation mechanism; the clamping turnover structure comprises a pair of manipulators, a pair of extensible cylinders which control movement of the manipulators and a pair of rotary cylinders which control rotation of the manipulators; the stroke compensation mechanism comprises a platform, a control cylinder which adjusts the height of the platform, buffer blocks and adjusting blocks which are convenient to replace; stroke differences compensated through the stroke compensation mechanism are gaps between the adjusting blocks and the buffer blocks; the gaps between the adjusting blocks and the buffer blocks are equal to height differences from two end surfaces of the hub to be performed turnover to respective tire installation surfaces. The on-line type turnover mechanism for the hub and an assembly line conveying belt are in no connection and accordingly a modular design of an assembly line is not damaged. The on-line type turnover mechanism for the hub is suitable for hubs in different sizes due to the fact that strokes of the on-line type turnover mechanism for the hub can be compensated and no damage is generated if the hub is dissymmetrical.

Description

technical field [0001] The invention relates to an automatic distribution system for parts in a workshop, in particular to an online wheel hub turning mechanism. Background technique [0002] In the automatic hub production line, it is often necessary to turn over the hub to meet the requirements of different processing positions and surfaces. Existing fully automatic turning mechanisms can be divided into two categories, namely off-line and on-line. [0003] The off-line type uses other devices to place the workpiece to be flipped on the flip surface, then locks the workpiece, flips it, finally unlocks it, and then puts the workpiece back on the conveyor belt. There are many procedures and low production efficiency, which is rarely used in automated production lines. Use this mechanism. [0004] In the online type, the turning mechanism is on the assembly line, and the workpiece is turned over on the conveyor belt. Compared with the off-line type, the intermediate transmi...

AI Technical Summary

Problems solved by technology

Although the existing online turning mechanism can solve the problem of low off-line production efficiency to a certain extent, there are generally the following three problems or deficiencies:

These make the assembly line conveyor belt with modular design destroyed, thereby increasing the design and manufacturing cost; the flexibility of combination and split between equipment and production line becomes poor, which brings troubles to equipment maintenance and production line upgrade

[0006] Second: The asymmetry of the workpiece being turned is basically not considered. For a special workpiece such as the wheel hub, its posture before and after turning is different. damage workpiece

[0007] Third: Generally, it cannot adapt to the large size change of the flipped workpiece in the flip direction, which leads to a flip mechanism that can only flip workpieces with fixed or small changes in size (size in the flip direction)
