Description

Technical Field

[0001] The utility model belongs to the technical field of diameter detection, and in particular relates to an EPS guide sleeve diameter detection device. Background Art

[0002] EPS is the abbreviation of Electric Power Steering, which refers to an electric power steering system that relies on an electric motor to provide auxiliary torque. The guide sleeve is an important mechanical component of the EPS system.

[0003] The detection of the inner hole diameter of the EPS guide sleeve is very important for controlling the processing quality of the EPS guide sleeve. There are many kinds of precision testing instruments on the market, such as the electronic column pneumatic micrometer, which has been very maturely applied in the size detection of structural parts. The measurement principle of the pneumatic measuring instrument is the comparative measurement method. The measurement method is to convert the length signal into an airflow signal, and indicate the value through the float in the scaled glass tube, which is called a float-type pneumatic measuring instrument; or the gas signal is converted into an electrical signal through a gas-to-electric converter, and the light column composed of the light-emitting tube is indicated, which is an electronic column-type pneumatic measuring instrument.

[0004] The measuring head of the electronic column pneumatic measuring instrument has a slot and an air nozzle, and is often used to measure the inner diameter of pipe components.

[0005] It was retrieved that in the prior art, a Chinese utility model patent with authorization announcement number CN217083690U discloses "a diameter detection device for EPS guide sleeve", which includes an electronic column pneumatic micrometer, a pneumatic plug gauge, a pneumatic inner diameter measuring nozzle, a three-way connecting pipe and an air pipe. The electronic column pneumatic micrometer, the pneumatic plug gauge and the pneumatic inner diameter measuring nozzle are connected by the three-way connecting pipe and the air pipe. The diameter detection device for EPS guide sleeve also includes: a base, the electronic column pneumatic micrometer is installed on the top surface of the base; a support plate; a positioning sleeve; and a straightening mechanism to avoid accidents in which the EPS guide sleeve is skewed. The operator does not need to hold the pneumatic inner diameter measuring nozzle and the EPS guide sleeve for detection, which is more convenient.

[0006] Although the diameter detection devices in the prior art, including those mentioned above, have the characteristic of stable detection, because the sizes and shapes of EPS guide sleeves of different specifications are different, that is, different measuring heads need to be replaced for EPS guide sleeves of different specifications. In addition, because the electronic column pneumatic micrometer needs to use an air pipe to connect the measuring head, direct replacement of the measuring head requires disassembly and assembly of the air pipe. Frequent disassembly and assembly of the air pipe can easily cause unstable connection and leakage, thereby reducing the accuracy of measurement.
