Description
Technical field
The invention belongs to field of mechanical technique, relate to a kind of device, particularly a kind of locking device of water meter clamp ring for the water meter assembling.
Background technology
Water meter is the instrument of measuring discharge.Its adopt the direct mechanical motion process of removable wall volumetric measurement chamber or flow rate of water flow to the work of wing wheel in order to the flowmeter of Flow through the current volume of water supply pipe.Such as the disclosed a kind of water meter [application number: 200420028186.3 of Chinese patent literature; Granted publication number: CN2711700Y].In addition, overwhelming majority of countries has also been formulated the relevant standard of water meter, such as IS04064-1:1993, the State Standard of the People's Republic of China GB/T778-2007 etc. of ISO (International Standards Organization).
At present, counter all is threaded on the housing; The disclosed a kind of water meter [application number: 200420028186.3 of above-mentioned Chinese patent literature; Granted publication number: CN2711700Y] be to adopt to be threaded.This water meter Counter and housing connecting portion place diameter also need counter is processed internal thread greater than diameter of the housing simultaneously, and housing is processed external thread.Obviously the volume that exists water meter is larger, and it is also more to produce required starting material, and production process is complicated, and then causes this water meter to have that producing cost is higher, good looking appearance is poor and the problem such as the market competitiveness is weak.
In order to solve the technical matters of above-mentioned existence, so once the someone had proposed a kind of syndeton that is different from above-mentioned water meter counter and housing, it comprises the annular convex ring that is positioned on the counter outer wall and annular groove and a snap ring that circumferentially seals of being positioned on the housing outer wall, the both sides of snap ring all have flange, the flange of one side is resisted against on the end face of annular convex ring, and the flange of opposite side makes its moulding and embedded rings connected in star by extruding and leans with the end face of annular groove.Although this structure has effectively reduced the volume of water meter and improved profile ground aesthetic property, still exist production cost height, problem that production efficiency is low.Its main cause is: the instrument of extruding snap ring opposite side flange is two compressing tablets, and compressing tablet lays respectively at the both sides of snap ring, and compressing tablet is connected with depression bar by lever principle or is separately fixed on the drift and worktable of punch press.Adopt manual extruding to exist the large and inefficient problem of labour intensity, also exist simultaneously extruding problem not in place.It is excessive to adopt punch ram to exist acting force, the problem of very easily suitable bad water meter.This shows that also not having at present can be fast and effectively finish the equipment of extruding snap ring opposite side flange.
Summary of the invention
The objective of the invention is to have the problems referred to above for existing technology, proposed a kind of locking device of water meter clamp ring, utilize this snap ring locking device can be fast and push equably snap ring opposite side flange.
Purpose of the present invention can realize by following technical proposal: a kind of locking device of water meter clamp ring, it is characterized in that, it comprises frame, described frame is provided with the locating slot for the location water meter, the outside of locating slot is provided with three compressing tablets at least, the end face of adjacent compressing tablet can lean and all compressing tablets can around rounded, be equipped with between each described compressing tablet and the frame and can make the compressing tablet driving mechanism that moves and the guiding mechanism that compressing tablet is moved along the locating slot radial line.
The counter of water meter or housing are positioned in the locating slot on the frame, and snap ring is also by Primary Location; Annular groove on the hull outside face is relative with compressing tablet, and the opposite side of snap ring is relative with compressing tablet and annular groove.Handle the driving mechanism in this snap ring locking device, driving mechanism promotes accordingly that compressing tablet moves along the locating slot radial line, and then snap ring opposite side flange in the water meter is squeezed in the annular groove on the hull outside face; Obviously, in the inner edge of the compressing tablet energy embedded rings connected in star.After the flange extrusion modling, driving mechanism drives the compressing tablet counter motion, and then finishes extruding snap ring opposite side overturning process.When utilizing the other side of this snap ring locking device extruding snap ring, all compressing tablets are synchronized with the movement, and can circumferentially push equably snap ring, so the flange that moulding obtains has shape evenly and cooperates with housing closely and advantage firmly.
