High-speed rail brake test tool clamp

Abstract

The invention discloses a high-speed rail brake test tool clamp, and belongs to the technical field of disc brakes. The high-speed rail brake test tool clamp comprises a base, wherein an upper supportframe is fixedly connected to the base, a plurality of guide columns are fixedly connected to a main plate of the upper support frame, and the guide columns are perpendicular to the main plate of theupper support frame, extend towards two sides, and are respectively connected with two clamp arms in a sliding and guiding manner; the two clamp arms are symmetrically arranged, and the relative positions of the two clamp arms are locked through cooperation of a plurality of fastening lead screws and nuts; the front end of each clamp arm is provided with a hydraulic cylinder, the working end of the hydraulic cylinder is detachably connected with a brake block shoe seat, and a brake block is installed on the brake block shoe seat. The high-speed rail brake test tool clamp is convenient to be installed on a test bench, convenient to adjust, capable of installing brake blocks of different specifications, and flexibly suitable for various test working conditions.

Description

technical field [0001] The invention relates to the technical field of disc brakes, in particular to a high-speed rail brake test tool pliers. Background technique [0002] At present, with the rapid development of my country's railway high-speed train industry, it has driven the rapid follow-up of accessories in the braking field of related equipment. Powder metallurgy brake pads are mainly used in disc brake devices in the high-speed rail field. The main material is metal powder and non-metal powder materials. Its high temperature resistance can reach 1000°C and it has excellent braking performance. When improving or testing the performance of friction materials, it is often necessary to conduct multiple bench tests. The brake calipers of each type of brake pads are often different. When different brake pads are used, the brake calipers often need to be replaced. However, for research institutes, brake manufacturers or brake pad manufacturers, it is often more expensive t...

AI Technical Summary

Problems solved by technology

The brake calipers of each type of brake pads are often different. When different brake pads are used, the brake calipers often need to be replaced. However, for research institutes, brake manufacturers or brake pad manufacturers, it is often more expensive to invest A lot of money, and the installation methods are different, and it needs to be equipped with a variety of installation tools to install on the brake stand

Moreover, under different braking test conditions, the specification, size and thickness of the brake disc often change, and the installation position may also change, which puts forward various requirements for the auxiliary installation tooling of the brake caliper.
