Novel overturning structure

Abstract

The invention relates to a novel overturning structure which comprises a bottom frame and a left overturning mechanism. The left overturning mechanism is equipped with a large suspension, a large suspension drive cylinder, a small suspension and a small suspension drive cylinder, wherein one end of the large suspension drive cylinder is fixed on the bottom frame by a lower hinge ear of a large drive cylinder, the other end of the large suspension drive cylinder is fixed on one end of the large suspension by an upper hinge ear of the large drive cylinder, and the other end of the large suspension is connected to a rotation shaft; and one end of the small suspension drive cylinder is fixed at the middle part of the large suspension drive cylinder by a lower hinge ear of a small drive cylinder, the other end of the small suspension drive cylinder is fixed at the middle part of the small suspension by an upper hinge ear of the small drive cylinder, and one end of the small suspension is connected to the rotation shaft. According to the invention, a shifting function, a welding function and an overturning function are integrated; and the structure is concise, efficient and practical.

Description

technical field [0001] The invention relates to the technical field of lifting and turning equipment manufacturing, in particular to a turning device. Background technique [0002] In the production process of special vehicles and other industries, displacement welding and process reversal of workpieces are necessary. A new type of reversal structure is often used to realize the displacement requirements of workpiece welding. In addition, due to the characteristics of welding parts production technology, displacement welding is required. Then turn the workpiece over a certain angle. For example, in the production of the semi-trailer frame, after the reverse assembly and welding, the entire semi-trailer frame should be turned 180 degrees to facilitate the subsequent process. There is a single-sided rollover device with single function and low efficiency in the existing new type of turning structure. It can meet the technical requirements of one side of the welding, and it sh...

Problems solved by technology

There is a single-sided rollover device with single function and low efficiency in the existing new type of turning structure. It can meet the technical requirements of one side of the welding, and it should be used correspondingly with another symmetrical displacement welding device. The overall (180 degree) flip after welding is relatively low in efficiency, and it is impossible to realize the overall flip after welding; the second is: a new type of flipping structure of the squirrel cage, which needs to be matched with the front and rear support rollers In addition, the range of workpieces to be adapted is small. Although the requirements for double-sided displacement welding can be completed at one station, it cannot meet the requirements of automatic unloading after the overall 180-degree flip of the workpiece after welding. In addition, the second The biggest disadvantage of the method is that the workload of the civil engineering is relatively large, because it has a problem of the radius of gyration. This kind of device generally needs to be matched with the pit on the civil engineering. To use this displacement welding device, a front and rear auxiliary transitional rolling table is required. The efficiency is low. In addition, this device cannot meet the turnover of products with irregular double sides of the workpiece, because this new type of turnover structure enters and exits the workpiece by relying on the front and rear roller tables and the rollers on itself. If the workpiece is irregular, even if it can be realized The 180-degree flip will also encounter problems when sending out the workpiece. Another disadvantage is that the manufacturing cost is high and the relative efficiency is low, which is not conducive to the flexible change of the production process.
