Metal bushing full-automatic measurement instrument

Abstract

The invention relates to the field of production detection, and particularly, relates to a metal bushing full-automatic measurement instrument. The metal bushing full-automatic measurement instrumentcomprises a cabinet, a vibration disk automatic loading machine and a detection table assembly; a horizontal separator is arranged at the middle part of the cabinet; the detection table assembly comprises a working table, a material passage, an upper limit detection mechanism and a lower limit detection mechanism; a first material pushing cylinder and a second material pushing cylinder which are used for pushing a metal bushing out of the material passage are respectively arranged right below the upper limit detection mechanism and the lower limit detection mechanism; a feeding cylinder for pushing the metal bushing in the material passage to move forwards is arranged outside the initial end of the material passage; and a first material box, a second material box and a third material box are arranged right below the working table. According to the metal bushing full-automatic measurement instrument disclosed by the invention, plus and minus tolerances of a product are detected in a comparing mode and according to different detection results, classified collection is implemented, so that recycling of a material is implemented; and meanwhile, the detection process is full automatic and efficiency is very high.

Description

technical field [0001] The invention relates to the field of product detection, in particular to a metal bush automatic measuring instrument. Background technique [0002] The bushing is an accessory used outside the mechanical parts to achieve sealing, wear protection, etc., and refers to the ring sleeve that acts as a gasket. In the field of valve application, the bushing is inside the valve cover, and corrosion-resistant materials such as polytetrafluoroethylene or graphite are generally used for sealing. In the moving parts, the wear of the parts is caused by long-term friction. When the gap between the shaft and the hole is worn to a certain extent, the parts must be replaced. Therefore, the designer chooses the one with lower hardness and better wear resistance when designing. The material is a shaft sleeve or a bush, which can reduce the wear of the shaft and seat. When the shaft sleeve or bush is worn to a certain extent, it can be replaced, which can save the cost ...

Problems solved by technology

[0003] In the current quality inspection process of bushing production, the axial dimension tolerance of the produced metal bushings is measured manually, and bushes exceeding the upper tolerance value (that is, positive tolerance) can be returned to the production line for processing, while low Bushings that are lower than the lower limit of the tolerance (that is, negative tolerance) cannot be used. The traditional inspection process is time-consuming and laborious, and the manual inspection method is often accompanied by inaccurate situations, which affects efficiency.
