Drawing force detector and test method thereof

Abstract

The invention discloses a bidirectional drawing force detector for a precise bushing and a test method of the detector. The drawing force detector includes a pedestal, a slide rail arranged on the pedestal, a double-end leading screw, left and right sliding tables mounted on the leading screw, a stepping motor arranged at one end part of the leading screw, a clamp supporting seat arranged in a middle part of the pedestal, and a clamp arranged on the clamp supporting seat and used for fixing a ceramic bushing sample, the left and right sliding tables are fixedly equipped with two oppositely arranged detection heads, each detection head comprises a detection insertion core, a connecting part and a force sensor, the stepping motor can drive the double-end leading screw and drive the detection heads on the left and right sliding tables to perform centering insertion and pulling drawing force detection movement on the ceramic bushing workpiece on the clamp. The equipment is high in precision and small in vibration, a return reset limit switch of the stepping motor is arranged, deviation of the detection heads on the sliding tables in reciprocating motion is reduced, test precision of the drawing force detector is improved, and the drawing force detector can serve as an instrument for calibration of an automatic detection machine.

Description

technical field [0001] The invention relates to the technical field of precision parts detection, and specifically discloses a precision casing bidirectional pullout force detector and a testing method thereof. Background technique [0002] The precision sleeve involved in the present invention belongs to the optical fiber connector. The optical fiber connector is a device for detachable (movable) connection between the optical fiber and the optical fiber. The energy can be coupled into the receiving optical fiber to the greatest extent, and the impact on the system caused by its intervention in the optical link is minimized. There are many types of fiber optic connectors, which can be divided into FC, SC, ST, MU, LC, etc. according to the connection method; according to the casing material, they can be divided into zirconia ceramic materials, SUS materials, glass materials, plastic materials, metal materials, etc. [0003] With the breakthrough and maturity of the most cut...

Problems solved by technology

[0005] However, in the process of applying the above-mentioned patented automatic testing machine products, the company found the following problems: (1) The automatic testing machine lacks equipment for its calibration, whether the measurement data of the automatic testing machine is accurate or not, and it is difficult for users to calibrate the testing equipment, and there is a lack of basis; (2) The automatic testing machine only measures the maximum pulling force, and automatically sorts the products according to this parameter, and only caches the maximum pulling force of 10 latest tested products in the PLC memory, and displays them on the LCD screen. Provide the force change data of the whole drawing process; (3) Based on the reason of (2), it is difficult to obtain the data of the drawing force of a batch of samples, and the data analysis of the drawing force cannot be realized, so it cannot be used for the equipment in the production-related process section. Appropriate adjustments to increase the rate of excellent products and reduce the rate of rework and scrap are to provide a reference for improving the production process
