Description
Technical field
The present invention relates to a kind of piston ring clamping device, relate in particular to a kind of clamp for composite lining ring of piston ring.
Background technology
In reciprocating gasoline engine, along with the continuous lightweight of engine, the working environment of piston ring is brought up to a more and more higher degree to its performance requirement.Because continually strengthening of engine, especially in the continuous pursuit high-performance of each side such as oil consumption, discharging, the piston ring technology has also obtained corresponding development and has obtained significant progress.Secondly send out in the sale of automobile market of looking flourishing day by day,, have higher requirement for the control functional oil of piston ring owing to improving constantly of energy-saving and cost-reducing and environmental protection consciousness.In order to comply with this historical development trend, the oil ring technology of internal combustion engine is also developed greatly and is improved.Formed development spiral grommet compound oil ring technology in diesel engine gradually; The general layout of development steel band compound oil ring (steel band ring) technology in gasoline engine.Look back steel band loop technique development course, can reduce several stages simply, the steel band grommet of the first generation is lined (a cast iron oil ring body inner lining steel band); The steel band ring of the second generation is split type (polynary combined type); The steel band ring of the third generation is combined type (forming S type, H type, U type three macrostructure forms gradually); The steel band ring in the 4th generation has been strengthened the crossette technology; The steel band grommet in the 5th generation has been strengthened the convex technology.
So-called crossette technology is the steel band grommet has increased a α angle to crossette and the axially mounting face of scraping after crossette portion that the loop inner headed face plays the radial support effect strengthens, and causes and scrapes the wall pressure of loop to piston ring groove, helps improving the oil-control ability of oil ring.
So-called boss technology is the steel band grommet to the scraping blade annulate shaft to supporting by face to the evolution of putting.Because " boss technology " strengthened the steel band grommet to scraping the axial fixed point supporting of loop, complements each other, brings out the best in each other with " crossette technology ", formed and reliably, effectively scraped the wall pressure of loop to annular groove, stably improved the oil-control ability of steel band ring.
H type complex loop grommet mainly uses mould manufacturing, but grommet tends to take place uncertain distortion in process, indefinite variation also can take place in the size at projection angle, the quality of grommet just is difficult to be guaranteed so, and then have influence on the steel band compound oil ring and get quality, therefore grommet projection angle is detected with regard to necessary.Because the lining ring of piston ring structure is special, does not have the suitable stationary anchor clamps, measurement can't be carried out smoothly.
Summary of the invention
It is wide and improve the clamp for composite lining ring of piston ring of clamping reliability and measuring accuracy to the invention provides a kind of applicability.
The present invention adopts following technical scheme:
A kind of clamp for composite lining ring of piston ring, comprise support and test desk, test desk is located on the support, test desk is made up of measuring table and clamping plate, one end of measuring table and clamping plate is rotationally connected, be provided with resilient supporting unit at measuring table, this resilient supporting unit is by spring, guide pillar and arc support block are formed, and arc support block is located at an end of guide pillar, and the other end of guide pillar is connected with measuring table, spring housing is located on the guide pillar and acts on arc support block, be provided with cylinder at measuring table and clamping plate, the cylinder body of this cylinder is fixedlyed connected with measuring table, and the piston rod of this cylinder is connected with clamping plate.
Compared with prior art, the present invention has following advantage:
The present invention can adapt to the variation of different rings specification, utilizes spring force to make the arc supporting surface be close to ring, and clamping plate are from the top clamping ring then, and when H type grommet was subjected to downward ergometry, grommet can not be out of shape downwards like this.This clamp structure is simple, adopts air pressure as power source, has avoided using the shortcoming of calutron magnetization grommet, be easy to adopt automation mechanized operation, sanitation and hygiene, arc support block and clamping plate collaborative work firm grip grommet are suitable for measuring the stationary installation at composite lining ring of piston ring projection angle.

Embodiment:
A kind of clamp for composite lining ring of piston ring, referring to Fig. 1,2, comprise support 10 and test desk, test desk is located on the support, test desk is made up of measuring table 9 and clamping plate 2, measuring table 9 is rotationally connected with an end of clamping plate 2, be provided with resilient supporting unit at measuring table 9, this resilient supporting unit is by spring 5, and guide pillar 6 and arc support block 8 are formed, arc support block 8 is located at an end of guide pillar 6, the other end of guide pillar 6 is connected with measuring table 9, and spring 5 is set on the guide pillar 6 and acts on arc support block 8, is provided with cylinder 1 at measuring table 9 and clamping plate 2, the cylinder body of this cylinder 1 is fixedlyed connected with measuring table 9, and the piston rod of this cylinder 1 is connected with clamping plate 2.Referring to Fig. 2,5, be provided with limited block 7 in the both sides of arc support block 8.Referring to Fig. 3,4, on measuring table 9, be provided with two holes, in these two holes, be respectively equipped with pillar 4, on two pillars 4, be connected with crossbeam 3, the other end of above-mentioned guide pillar 6 is connected with this crossbeam 3.
