Embodiment 1

[0014] like figure 1 As shown, the technical solution provides a detection device for satellite-specific round nuts, including a platform for placing the round nuts to be tested 1, a frame, a detection mechanism and a transport mechanism. The transport mechanism includes a rotating arm 2 and a reciprocating transmission device. , a limit sleeve 5 and a horizontally telescopic pick-up device 6, and the rotating arm 2 can swing back and forth horizontally by 90°. The reciprocating transmission device is installed vertically and fixedly under the rotating arm 2. The reciprocating transmission device can be driven by the oil pressure cylinder, the cylinder 3 or the cam mechanism. In this scheme, because the round nut 1 to be tested is light in weight, the output load is used Smaller cylinder 3 to drive. The output shaft 4 of the cylinder 3 is equipped with a horizontally expandable pick-up device 6 , the limit sleeve 5 is fixedly connected to the cylinder 3 , and the output shaft...

Embodiment 2

[0017] like figure 2 As shown, this embodiment is the same as Embodiment 1, and the difference is that in this embodiment, the pick-up device 6 includes two pick-up rods 7 hinged at the bottom of the output shaft 4 and a pressing rod connected between the two pick-up rods 7 . Spring 8, when cylinder 3 output shaft 4 is in retracted state, two pick-up rods 7 are drawn in by limit sleeve 5, when cylinder 3 output shaft 4 is in extended state, two pick-up rods 7 break away from the shackles of limit cylinder 3 and Under the action of the compression spring 8, it expands to the left and right respectively along its hinge point. The end of the pick-up rod away from the output shaft 4 is made of rubber. Because the rubber is soft and has a large friction coefficient, when the pick-up rod contacts the inner wall of the round nut 1, the friction between the two is increased to avoid the friction of the round nut 1. Shedding problem.

Abstract

The invention relates to a detection device for special round nuts for satellites, which includes a frame, a detection mechanism and a horizontally rotatable transport mechanism. It is vertically arranged under the frame, and the pick-up device is set on the output shaft of the reciprocating transmission device. The limit sleeve used to control the expansion and contraction of the pick-up device is sleeved on the output shaft. The detection mechanism is set under the transport mechanism. The detection mechanism It includes a circular chassis and several detection shafts connected to the edge of the chassis. The diameter of the chassis is smaller than the outer diameter of the round nut. Elastic parts are connected between the detection shafts to form a horn shape between the detection shafts. Angle measuring device for shaft deflection angle. Through the implementation of the technical solution, the problems of the inconvenience caused by the constant replacement of detection tools and the uncertainty of the detection accuracy caused by humans in the existing detection technology for round nuts are solved.

Description

technical field [0001] The invention is applied in the detection field, and in particular relates to a detection device for a special round nut for satellites. Background technique [0002] The manufacturing and processing of satellites is a very precise process, and the specifications, parameters, and quality of each component must be strictly determined, otherwise it will lead to unstable performance of the satellite during launch, resulting in accidents such as deviation from the trajectory or explosion. The round nut is used in conjunction with the stop washer to axially fix the rolling bearing on the satellite. When assembling, insert the inner tongue of the stop washer into the groove on the shaft, and insert the outer tongue of the washer into the groove of the round nut, and the nut is locked. Since the round nut is surrounded by various parts, if the outer diameter of the round nut is too large, it will interfere with the normal operation of other parts. If the out...
