Two-way insertion and withdrawal force detection device for precision pipe fittings

Abstract

Provided is a bidirectional insertion and extraction force detecting device for accurate pipe fittings. A left cam and a right cam on a rotating shaft are tightly attached to a left bearing and a right bearing, the left bearing and the right bearing are respectively arranged on a left slide rest and a right slide rest, a locating mould and two guide rails are fixed on a bottom plate, the two guide rails are matched with two slide grooves formed in the left slide rest and the right slide rest respectively, a connecting rod and a measuring rod are integrally connected through a force cell, the connecting rod and the measuring rod are arranged on the left side rest and the right slide rest respectively, and a measuring head matched with a work piece on the locating mould is fixed to one end of the connecting rod. Due to the fact that the left cam and the right cam are matched with the left bearing and the right bearing which are arranged on the left slide rest and the right slide rest respectively to achieve synchronous linkage, the accuracy and the measurement stability for an insertion core of the measuring head to be directly inserted into and pulled out of the work piece are guaranteed. The force cell is connected with a linear bearing through the connecting rod to enable measurement to be more accurate. The left cam and the right cam are face cams, so that the processing accuracy is high. All mechanical actions of the device can be achieved through the mechanical linkage between a motor and the accurate face cams. The bidirectional insertion and extraction force detecting device is simple in structure, greatly reduces useless idle stroke and supply delay time, can detect 60 work pieces in one minute, is high and stable in detecting speed and is high in work efficiency.

Description

technical field [0001] The invention relates to an important part of an automatic detection machine for precision pipe fittings, in particular to a precision pipe fitting bidirectional insertion and withdrawal force detection device for internal butt joint of optical fiber connectors. Background technique [0002] Optical fiber connector is a device for detachable connection between optical fiber and optical fiber. It precisely butts the two end faces of the optical fiber so that the optical energy output by the transmitting optical fiber can be coupled to the receiving optical fiber to the maximum extent. The impact on the system caused by its intervention in the optical link is minimized, and its core part: the ceramic sleeve is the most important part to ensure the seamless connection of two ultra-precision optical fiber connectors. The allowable tolerance of the inner hole of the ceramic sleeve is only About 2 microns, if the processing is slightly out of tolerance, the ...

Problems solved by technology

However, at present, most of the existing ceramic sleeve manufacturers use manual inspection, not only the production efficiency is not high, but also the detection accuracy and consistency are not ideal, and the conventional inner hole size detection method cannot achieve such high-precision and large-scale detection. It is also an important factor that greatly restricts the quality and stability of optical fiber connectors

[0003] Patent Application No. CN201120414778.9 "Ceramic Casing Bidirectional Pulling Force Automatic Detection Device" Although it also provides a machine detection instead of manual detection, which improves the efficiency of production inspection, but its detection speed is not fast enough, detection stability, detection Accuracy is not high enough
