Description
Technical field
The present invention relates to a kind of piston ring automatic detection device.Three station piston ring light leak degree and end-gaps automatic tester and the calibrating block thereof that particularly relate to a kind of middle-size and small-size piston ring finished product detection for automobile (or motorcycle) engine.
Background technology
The light leak degree of piston ring refers to tested piston ring is pressed into the ring standard gauge of cylinder base diameter, observe both in conjunction with situation, to the statistical information that may exist along its contact circumference, allow the slit that the certain strength light beam passes through.The light leak degree is actually the bubble-tight presentation that piston ring was combined with piston, cylinder wall in when work, because being easy to detection, usually with light leak degree information as one of index of measurement piston ring quality.After the end-gaps of piston ring namely is pressed into the ring standard gauge of cylinder base diameter, the size in slit, piston ring in sealed place.As shown in Figure 1, piston ring 54 is placed in the ring standard gauge 22, check the size of piston ring 54 end-gaps 51 and light leak light slit 90.
Piston ring is as one of key components and parts of engine, and its light leak degree and end-gaps directly affect work efficiency and the exhaust emissions quality of engine integral body.National standard has strict regulation to these two parameters, requires before dispatching from the factory piston ring to be carried out checking piece by piece, rejects unacceptable product.And piston ring is typical products in mass production, and the market demand is very big, and this has proposed very high requirement for the efficient that detects.But limited by technical conditions, the at present domestic still manual methods that adopt detect more.As shown in Figure 2, piston 54 rings are placed in the ring standard gauge 22 of cylinder base diameter, with light source 91 shine from bottom to top piston ring 54 outer walls and ring gauge 22 in conjunction with circumference, manual rotation ring gauge 22 with the naked eye 92 is observed the light leak of piston ring end gap clearance and whole circumference and is estimated total light leak arc length and distribution situation.Manual detection must be introduced tester's subjective factor, causes the inaccurate of testing result, and detection efficiency is low, and the long-term work meeting causes damage to workman's eyesight.
" light-leakage testing apparatus for piston ring of internal-combustion engine " (application number: CN88219395), alleviated to a certain extent the working strength of manual detection piston ring light leak degree of the full design of Mechanical Research and Design Inst., Jiangsu Prov Chen Ting in 1988.Along piston ring and ring gauge in conjunction with 72 luminescent devices of even circumferential array as static contact, survey the light leak degree with photoelectric sensor as moving contact, its resolving power only is 5 °, can't differentiate for trickle light slit and point-like light leak.Need manually piston ring to be pressed into ring gauge in this invention in addition, still can not break away from the dependence to the people, job costs height and efficient are restricted.
" piston ring quality of internal combustion engine detects and automatic sorting device automatically " of the extra large mound internal combustion engine part head factory motorcycle Zhang Tongyu of the subsidiary factory design of Sichuan Province's Fuling City (existing Chongqing City Fuling District) in 1994 (application number: CN93238721.7), be that a cover can be with the device of machine testing piston ring light leak degree and two indexs of end-gaps.Mentioning in this invention with optical CCD and detect the light leak degree, is a kind of bold conception at that time.The layout of its conception is by the turning to of catoptron, allow CCD camera distance ring gauge certain once take at a distance piston ring and ring gauge in conjunction with situation.But the existence of the position of catoptron and center pole all shows in its structural drawing, and this structure can't disposablely be obtained piston ring circle complete information.In addition, because piston ring light leak slit is very faint, if CCD is not in directly over the local light slit, light leak information defies capture.Existing manual detection has also proved this point.
" piston ring automatic tester " (appearance patent application number: CN200830206848) by the common development of University Of Tianjin and CSR Qishuyan Locomotive ﹠ Rolling Stock Technology Research Institute in 2008, be an automatic detection system that is applied to diesel locomotive engine large scale piston ring, can detect simultaneously two indexs of light leak degree and end-gaps.Because the Diesel Locomotive Piston ring size is larger, the light leak slit is also large, and circumferential resolution is less demanding, and its light leak information is gathered by the high sensitivity photodiode, as shown in Figure 3, wherein 93 is sensors, the 54th, and piston ring, the 22nd, ring gauge, the 94th, extender lens, the 91st, light source.For the middle-size and small-size piston ring of micro gap, then not competent.
The piston ring detecting instrument that also has in addition some institutes's designs, perhaps principle exists defective can not satisfy accuracy, the repeatability of detection, can't realize that perhaps robotization detects, and perhaps is not suitable for the high middle-size and small-size piston ring of accuracy requirement.In addition, in the past design single station, the ring gauges of adopting rotate and the fixing method of sensor more, and detection efficiency has been subject to significantly restriction.
