Turning machine for assembly and construction machinery base assembly device

Abstract

The invention discloses a turnover machine for assembling. The turnover machine comprises a machine seat and a pair of turnover manipulators arranged on the machine seat, wherein the turnover manipulators comprise turnover arms, turnover elbows, first insertion pin cylinders, second insertion pin cylinders and turnover hydraulic cylinders. The invention also discloses a base assembling device for engineering machinery. The base assembling device for the engineering machinery comprises vehicle rails and a transporting vehicle which is arranged on the vehicle rails and is used for transporting a base of the engineering machinery. According to the turnover machine for assembling and the base assembling device for the engineering machinery, taking and arrangement of a workpiece to be turned over are realized by controlling insertion pins to be inserted into and released out of the workpiece by the insertion pin cylinders; the turnover elbows and the turnover arms are controlled to integrally rotate around a hinge center, and the turnover arms are controlled to be fixed and the turnover elbows are controlled to rotate independently, so that the turnover machine can catch up and put down the workpiece and enable the workpiece to randomly rotate between 0-90 degrees; a large-size workpiece can be turned over conveniently through the turnover machine; the working efficiency for assembling parts on the upper surface and the lower surface of the large-size workpiece is improved; the assembling work is high in safety; the turnover machine is applicable to large-batch production.

Description

technical field [0001] The invention relates to a mechanical device, in particular to a turning machine. Background technique [0002] The base of construction machinery is usually a basic part, and many parts and components need to be installed on the upper and lower sides of the base. Therefore, the base must be able to turn and stop arbitrarily within the range of 0°~90° during installation to facilitate assembly. However, since the weight of the construction machinery base is generally between 0.5 and several tons, the weight and size of the base are relatively large, making it difficult to turn over and assemble. [0003] In the prior art, when assembling parts on the base of construction machinery, the base is covered and turned over by using a workshop crane and a lasso, or a cantilever crane or a half door crane, or a KBK crane is used to turn the base over. The flipping operation is difficult, it is easy to damage the workpiece and the staff, the assembly efficienc...
