Problems solved by technology

When installing the traditional crankshaft structure, due to the structure of the crankshaft, the crankshaft cannot be directly inserted into the installation. The bearing bush and the part where the bearing bush is installed must be split. In the case of heavy load and long-term impact load, it is easy to cause split connection. The part is loose, resulting in a larger gap between the crankshaft and the bearing bush, which affects the punching accuracy of the press
At the same time, the installation of the split connection is also relatively cumbersome, and the assembly requirements are high, which brings difficulties to the production work.

Abstract

The invention provides a crankshaft mounting structure, comprising a crankshaft (1) and an upper cross beam (2), wherein the crankshaft (1) is provided with three coaxial connection rod necks (1.1), each connection rod neck (1.1) is provided with three synchronously moving connection rods (7), two sides of each connection rod neck (1.1) are provided with main shaft necks (1.2) arranged on the crankshaft (1), and the main shaft necks (1.2) is in sliding matching with a main shaft radial support (2.1) arranged on the upper cross beam (2). The crankshaft mounting structure disclosed by the invention has the advantages of simple structure and convenience for mounting.

Description

Technical field [0001] The invention involves the field of mechanical technology, especially a pressure machine, specifically a crankshaft installation structure for pressure machines. Background technique [0002] Because the crankshaft of a high -speed pressure machine is a key part of the pressure machine, it plays a role in supporting and passing the tailoring.When the traditional crankshaft structure is installed, due to the crankshaft structure, the crankshaft cannot directly penetrate the installation. The part of the shaft and the installation bearing must be divided.Loose parts, resulting in a large gap between crankshaft and bearing, affecting the accuracy of the pressure machine.At the same time, the connection installation of the division is also cumbersome, the assembly requirements are high, which brings difficulty to the production work. Invention content [0003] The primary technical problem to solve the present invention is to provide a simple and easy -to -ins...
