Problems solved by technology

The measured value of this manual spring tester is inaccurate, and the repeatability is poor; it can only measure reeds below about 14KHz, and the measurement of flat springs is even more inaccurate; the measurement efficiency is low, and only about 3000-4000 pieces can be completed per day.

Embodiment Construction

[0024] Such as figure 1 , 2 As shown, the present invention includes an electromagnetic weight applying mechanism 1, a CCD displacement measuring unit 2, a drive and control system 3, a leaf spring measuring platform 4, a leaf spring feeding mechanism 5 and a leaf spring unloading mechanism 6, and a leaf spring feeding mechanism 5 The spring piece 41 is sent to the spring piece measuring platform 4, and the electromagnetic weight applying mechanism 1 sends the load force to the top of the spring piece 41 on the spring piece measuring platform 4, so as to add a suitable measuring force, and the CCD displacement measuring unit passes through The CCD camera system and the optical amplification system measure the displacement and deformation of the spring sheet 41 after loading, and send it to the drive and control system 3 to automatically control the output signal of the CCD displacement measurement unit 2, and display the measurement results, and then the spring sheet is lowere...

Abstract

An automatic monitor of spring blade at least comprises spring blade testing work table for placing the spring blade; electromagnetic weight reinforcing mechanism for loading the load moment onto thespring blade; CCD displacement measurement unit for forward and outward the spring blade; drive and control system for driving and controlling the reinforcing of electromagnetic weight, feeding and blanking structure of spring blade, in addition controlling automatically the signals ejected from CCD displacement measurement unit and displaying the measuring results.

Description

technical field [0001] The invention relates to a detection instrument, in particular to an automatic detection instrument for a spring used in a geophone. technical background [0002] At present, various literatures or materials openly introduce spring detection equipment used in geophones of geophysical instruments. In the mid-1980s, a manual spring detection device was developed in China. The piece is placed on the measuring seat, and then the measuring head is placed on the spring piece, the elastic force can be displayed digitally and classified according to the number. The measured value of this manual spring tester is inaccurate and has poor repeatability; it can only measure reeds below about 14KHz, and the measurement of flat springs is even more inaccurate; the measurement efficiency is low, and only about 3000-4000 pieces can be completed per day. It is understood that the spring tester used by Sercel abroad is to add a fixed measuring force, and then measure th...
