Problems solved by technology

Due to the installation of the alloy probe, there may be scratches on the high-precision surface, which is not allowed in many application fields. If a softer alloy is used, it is easy to cause wear. At the same time, due to the principle of the transformer, electromagnetic interference will Its influence is greater

Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0015] Such as figure 1 as shown, figure 1 It is a structure diagram of the present invention, and one end of the shell 2 is provided with a sensing head 1, the sensing head 1 is a reflective optical fiber displacement sensor, the installation of the sensor adopts two sensing heads installed on opposite diameters, and the optical fiber bundle structure is selected with the same axis alignment. The shell 2 can be made of aluminum alloy, which is light in weight and easy to carry. The surface of the casing 2 is designed as a convex structure along the axial direction, which is convenient for better grasping, and the measurement accuracy is affected by the slight sliding on the surface.

[0016] A signal processor 3 and a display 4 are arranged in the housing 2, and the output signal of the sensor is sent to the signal processor 3 for processin...

Abstract

The invention discloses an optical fiber type electronic plug gauge, and relates to a measuring instrument. One end of a shell is connected with a sensing measuring head; a signal processor is arranged in the shell; and a display screen is arranged on the shell. Output signals of the sensing measuring head are sent to the signal processor to be processed and displayed through the display after being output. According to the invention, an optical fiber displacement sensor is adopted; non-contact detection is achieved; the surface of a measured workpiece is not scratched, and the measurement precision is not affected; and meanwhile electromagnetic interference can be avoided.

Description

technical field [0001] The invention relates to an inner diameter measuring instrument, in particular to an optical fiber electronic plug gauge. Background technique [0002] The electronic plug gauge is an instrument used for high-precision inner diameter measurement. It has the advantages of high measurement efficiency, convenient use, and digital display of the results. At present, the sensor in the electronic plug gauge generally adopts the principle of an open differential transformer, and two carbide probes mounted on opposite diameters are used to measure the diameter. Due to the installation of the alloy probe, there may be scratches on the high-precision surface, which is not allowed in many application fields. If a softer alloy is used, it is easy to cause wear. At the same time, due to the principle of the transformer, electromagnetic interference will Its influence is greater. Contents of the invention [0003] In order to solve the above-mentioned technical ...
