Pressure head special for spoke noise reduction plate and calibration method of contact acting force

Abstract

The invention relates to the technical field of machine tool accessory devices, in particular to a pressure head special for a spoke noise reduction plate and a calibration method of contact acting force. The pressure head special for the spoke noise reduction plate comprises a ram, a core body, an installation base, a floating seat, a rolling wheel support and a measuring element, wherein the ramis connected with a machine tool body; the core body is provided with a piston part, a shaft shoulder part and a first guide part which are sequentially and coaxially arranged from top to bottom; a containing cavity is formed in the installation base, the opening port of the containing cavity is provided with a flexible sealing gasket which is in sealing connection with the containing cavity, a pressure transmission medium is arranged in the containing cavity, the upper top face of the piston part is in contact connection with the sealing gasket; the floating seat is connected with the firstguide part in an up-and-down sliding manner, a disc spring sleeves the first guide part, and the upper end of the disc spring abuts against the shaft shoulder part, and the lower end of the disc spring abuts against the floating seat; one end of the rolling wheel support is connected with the floating seat, and the other end of the roller support is provided with rolling and pressing wheels; and the measuring element communicates with the containing cavity. According to the device, a disc spring tight pressing the floating structure is adopted, so that the contact force value is accurately measured, and the compression joint quality of the spoke noise reduction plate is guaranteed.

Description

technical field [0001] The invention relates to the technical field of machine tool attachments, in particular to a special indenter for a spoke noise reduction plate and a method for calibrating contact force. Background technique [0002] With the continuous development of society, bullet trains and high-speed rails have become very important means of transportation in our lives due to their fast and convenient features. While bullet trains and high-speed rails bring convenience to people, the noise caused by their high-speed movement also has a certain impact on people's lives. The main noise source of bullet trains and high-speed rail is the high-speed moving wheels, so controlling wheel noise is the key to reducing the noise of bullet trains and high-speed rail. [0003] The spoke noise reduction board is made of composite materials through special processing, which has good functions of absorbing vibration and reducing noise. The installation quality of the spoke noi...
