Automatic bolt tightening machine for wheel brake disc

Abstract

The invention discloses a tightening machine and particularly relates to an automatic bolt tightening machine for a wheel brake disc. The automatic bolt tightening machine comprises a main body and an electric control cabinet, wherein the main body is connected with the electric control cabinet and comprises a column steel frame and a horizontal steel frame; a vertical guide rail and a lifting cylinder are arranged on the column steel frame; a tightening device is movably mounted on the vertical guide rail in a clamped manner and fixedly connected with the piston rod of the lifting cylinder; the horizontal steel frame is arranged right below the tightening device and connected with the column steel frame; a horizontal moving cylinder and a horizontal guide rail are arranged on the horizontal steel frame; an automatic rotary workbench is mounted on the horizontal guide rail in a clamped manner and fixedly connected with the piston rod of the horizontal moving cylinder. The automatic bolt tightening machine for the wheel brake disc is convenient to operate, can effectively reduce the labor intensity of operators and ensure the precision and quality of tightening and assembly of bolts for the wheel brake disc.

Description

technical field [0001] The invention relates to a tightening device, in particular to an automatic tightening machine for wheel brake disc bolts. Background technique [0002] As the speed of railway vehicles increases and the load increases, the requirements for braking are also getting higher and higher. The traditional simple brake shoe braking method can no longer meet the requirements, and in the disc brake, as the brake disc structure of the friction pair, a variety of options can be selected according to the braking requirements to meet the relatively large braking force requirements. Therefore, disc brakes have been developed rapidly on railway vehicles. [0003] As one of the forms of brake disc installation, the wheel-disc structure has been widely used, represented by high-speed trains such as high-power locomotives and EMUs. The wheel disc type is an installation method in which the brake disc is installed on the wheel for friction braking. This structure is to...

[0004] The patent with the application number 201120074235.7 discloses a bolt tightening machine for wheel-mounted brake discs of EMUs. The brake disc has twelve groups of bolts, which can be tightened evenly in two times to meet the bolt tightening torque accuracy requirements, but each time the tightening needs to manually rotate the wheel disc and operate the tightening machine box down to align, so that the tightening machine pull The sleeve is inserted into the bolt to be tightened to tighten, and then the box and the reaction mechanism are manually withdrawn from the bolt after completion, which is labor-intensive
