Mounting structure of long shaft of assembling machine clamping device

Abstract

The invention relates to a mounting structure of a long shaft of an assembling machine clamping device. A mounting box is arranged in a rack, vertically concentric mounting holes allowing the long shaft to be mounted are formed in the top and the bottom of the mounting box, the long shaft penetrates into the mounting holes in the top and the bottom of the mounting box from top to bottom, a supporting step is arranged on the long shaft, the long shaft is sleeved with an upper supporting bearing, the supporting step on the long shaft is supported by the upper end face of the upper supporting bearing, the upper supporting bearing is arranged in an upper bearing pedestal and is sealed by an upper shaft cover, and the upper bearing pedestal is fixedly arranged at the top of the mounting box through a screw; the long shaft is sleeved with a lower supporting bearing, the lower supporting bearing is arranged on a lower bearing pedestal and is sealed by a lower shaft cover, and the lower bearing pedestal is fixedly arranged at the bottom of the mounting box through a screw. The mounting structure is reasonable, can guarantee that the long shaft rotates flexibly, and is safe and reliable, then, the clamping device can precisely control the relative positions of a web plate and a wing plate, and the assembling precision, machining efficiency and automation degree of H-shaped steel are improved.

Description

technical field [0001] The invention relates to an installation structure for a long axis of a clamping device of an assembly machine, and belongs to the technical field of steel structure processing and manufacturing. Background technique [0002] With the rapid development of my country's steel structure industry, the H-beams used in steel structure workshops are increasingly becoming more refined and efficient. How to improve the assembly accuracy, processing efficiency and automation of H-beams has become a must for the steel structure industry. problem. [0003] H-shaped steel is assembled from two flanges and one web, and the relative positional relationship between the web and the flange directly affects the pass rate of the finished H-shaped steel. Existing general assembly machines all carry out artificial position setting to the assembly welding of required H-shaped steel in advance, and then carry out H-shaped steel assembly welding. And adopt this method, not on...

Problems solved by technology

However, with this method, not only the position of each plate cannot be accurately located, but more importantly, it is often limited to the welding of one type of H-shaped steel, the scope of application is narrow, and the production efficiency is not high.
