Description
Technical field
The utility model relates to a kind of jig making tool, especially relates to a kind of engine crankshaft front oil seal press-loading device.
Background technology
Oil sealing refers to the mechanical organ of Seal Oil, and is multiplex in the sealing of lubricating oil, and it avoids the seepage of lubricating oil with lubricating component in the drive disk assembly and miscellaneous part isolation.The engine crankshaft front oil seal press-fit approach is generally manual operations at present, automaticity is not high, such as notification number be: a kind of frock that oil seal for crankshaft of engine is installed that the Chinese utility model of CN201325029Y provides, by targeting part and with it adaptive press-fit portion be grouped into.Described targeting part has spigot surface.Described targeting part front end is provided with crankshaft rear end and cooperates the projection that frock is positioned, described targeting part rear end to be provided with the short handle that insertion press-fits part.Described press-fit portion is divided into the step hollow cylinder, and the press-fit portion sub-headend is the press-assembling surface of oil sealing, and there is the conduit that is slidingly matched with targeting part rear end short handle the rear end.Described targeting part spigot surface is arc-shaped transitional surface.Described targeting part front end is provided with cannelure.This patent exists and press-fits height and can not disposablely reach technological requirement, and it is larger affected by personnel's technical merit, and it is bad to press-fit uniformity, and operation is the problem such as inconvenient also.
The utility model content
The utility model mainly is low for the existing operation inconvenience of manual operations, automaticity for available engine crankshaft front oil seal-mounting press-fit approach, press-fit the poor problem of uniformity, provide a kind of easy to operate, to press-fit efficient height, automaticity high, press-fits preferably engine crankshaft front oil seal press-loading device of uniformity.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of engine crankshaft front oil seal press-loading device, it comprises cylinder, be fixed with movable pressure head on the piston rod of cylinder, be fixed with the magnetic patch for the absorption Front oil seal on the movable pressure head, be connected with upper press cover and lower cover in the movable pressure head activity, be provided with Compress Spring between upper press cover and the lower cover.Press-fiting of engine crankshaft front oil seal generally is that Front oil seal is fitted on the seal of timing cover chain, because the sheet metal that generally all can be provided for gaining in strength in the Front oil seal, so can adsorb Front oil seal by magnetic patch, movable pressure head moves with piston rod, under the drive of cylinder Front oil seal is being fitted on the timing cover chain, Compress Spring is used for movable pressure head is resetted, in order to press-fit next time, upper press cover and lower cover are used for carrying out spacing to Compress Spring.This press-loading device automaticity is high, only needs operator's console switch to get final product, and a plurality of Front oil seals can be adsorbed on the magnetic patch of movable pressure head successively, press-fit the efficient height, and it is better to press-fit uniformity, is particularly useful for factory's streamline production operation.
As preferably, offer limited ring groove on the outer wall of described movable pressure head, lower cover is connected in the limited ring groove, and the outer rim of movable pressure head extends to form downwards places restrictions on the limit, the distance of limited ring groove lower end to movable pressure head lower end is less than the length of placing restrictions on the limit, and lower cover and movable pressure head are slidingly connected.Place restrictions on the limit and can be resisted against on the timing cover chain, then movable pressure head presses down Front oil seal is press-fited, thereby the distance of limited ring groove lower end to movable pressure head lower end should be less than the length of placing restrictions on the limit.Limited ring groove defines the sliding distance of lower cover on movable pressure head, avoids damaging by pressure Front oil seal and timing chain cover.
As preferably, described upper press cover is nested with on movable pressure head, is fixed with shaft block ring on the movable pressure head, and shaft block ring and upper press cover are conflicted.Upper press cover is connected with movable pressure head, and by the shaft block ring location, it is firm to connect.
As preferably, the outer rim of described upper press cover extends to form the coated side that coats Compress Spring downwards.Coated side plays position-limiting action, can prevent that Compress Spring from skidding off upper press cover.
As preferably, be provided with screw thread on the inwall of described movable pressure head, movable pressure head is connected with piston rod thread.Movable pressure head is connected with piston rod thread, and movable pressure head can move with piston rod, and can adjustment activity pressure head and timing cover chain between distance, guarantee that the height that Front oil seal press-fits meets the demands.
As preferably, described magnetic patch is magnet steel, and magnetic patch has four, and four magnetic patch evenly are embedded the lower surface at movable pressure head.Magnet steel is the superhard permanent magnet that is supported by alnico alloy, can be used for adsorbing Front oil seal; Four magnetic patch adsorption capacities are stronger, and Front oil seal is stressed evenly.
As preferably, be connected with clamp nut on the described piston rod, clamp nut and movable pressure head are conflicted.Because piston rod is threaded with movable pressure head, connects clamp nut on the piston rod, be used for preventing that movable pressure head is loosening.
Therefore, the beneficial effects of the utility model are: by cylinder drive activity ram movement, Front oil seal is fitted on the timing cover chain, automaticity is high, press-fits high conformity, and it is low to avoid press-fiting the efficient of bringing by hand, press-fits the poor problem of uniformity.
