Abstract
The utility model belongs to the improvement of guide pin bushing frock of locomotive diesel engine piston group installation structure, especially a guide pin bushing frock of locomotive diesel engine piston group installation, organize including the cylinder jacket with cylinder jacket matched with piston, piston group comprises piston and piston ring, and the piston ring is installed in the annular of piston, and annular its hole of guide pin bushing frock of circle is the bell mouth, and the tip diameter and the cylinder jacket internal diameter of bell mouth lower extreme equal that the main aspects diameter on bell mouth upper portion is greater than the external diameter of piston ring, set up the ring concave station that sets up on ring boss and the cylinder jacket up end and match on the lower terminal surface of guide pin bushing frock. The utility model discloses rational in infrastructure, simple, during the maintenance operation swift, convenient, can prevent piston ring breakage, pull the cylinder jacket, labour saving and time saving can improve the maintenance progress of locomotive.
Description
Technical field
The utility model belongs to the improvement of the guide pin bushing tool structure that locomotive diesel engine piston group is installed, the guide pin bushing frock of particularly a kind of locomotive diesel engine piston group installation.
Background technology
Locomotive is when overhauling diesel engine, need the piston on diesel engine and piston ring all to pull down to carry out examine and replace, due to piston work in cylinder jacket be by piston ring portion oil and sealing just can normally work, so how piston, piston ring are installed in cylinder jacket particularly important, there is no special tooling in the past, during assembling with bottle opener by piston ring top in piston ring annular groove, depress piston again, fill and badly piston ring breakage may be caused not have sealing be used as, also may pull cylinder jacket generation equipment breakdown.A diesel engine has 16 piston groups, requires great effort, time-consumingly affects repair schedule during maintenance.
Utility model content
The purpose of this utility model is the guide pin bushing frock providing a kind of locomotive diesel engine piston group to install, it is rational in infrastructure, simple, swift to operate during maintenance, convenient, can prevent piston ring breakage, pull cylinder jacket, time saving and energy saving, the repair schedule of locomotive can be improved.
The purpose of this utility model is achieved in that the guide pin bushing frock that a kind of locomotive diesel engine piston group is installed, the piston group comprising cylinder jacket and match with cylinder jacket, piston group is made up of piston and piston ring, piston ring is arranged in the annular groove of piston, its endoporus of guide pin bushing frock of annular is bellmouth, the end diameter of bellmouth lower end is equal with inner diameter of cylinder sleeve, the outside diameter on bellmouth top is greater than the external diameter of piston ring, the lower surface of guide pin bushing frock arranges annulus boss and matches with the annulus concave station that cylinder jacket upper surface is arranged.
The utility model be one high 100 millimeters, in bottom, warp is the same with warp in cylinder jacket is all 240 millimeters, conical surface cover through being greater than 240 millimeters in top, be used for piston ring progressively to clamp-on in the annular groove on piston, a bottom processing boss, can be set on the concave station in cylinder jacket and play positioning action.Such piston is squeezed into piston ring by downward gravity in the annular groove on piston, and piston group is installed in cylinder jacket stably, quick and easy when reaching maintenance, prevents equipment breakdown object.
The utility model is rational in infrastructure, simple, swift to operate when achieving maintenance, convenient, prevents piston ring breakage, pulls cylinder jacket, time saving and energy saving, improves the repair schedule of locomotive.
Accompanying drawing explanation
Be further described the utility model below in conjunction with accompanying drawing, Fig. 1 is using state structural representation of the present utility model.
Detailed description of the invention
The guide pin bushing frock that a kind of locomotive diesel engine piston group is installed, as shown in Figure 1, the piston group comprising cylinder jacket 1 and match with cylinder jacket 1, piston group is made up of piston 2 and piston ring 3, piston ring 3 is arranged in the annular groove of piston 2, its endoporus of guide pin bushing frock 5 of annular is bellmouth, the end diameter of bellmouth lower end is equal with inner diameter of cylinder sleeve, the outside diameter on bellmouth top is greater than the external diameter of piston ring 3, the lower surface of guide pin bushing frock 5 arranges annulus boss 4 and matches with the annulus concave station that cylinder jacket 1 upper surface is arranged.The end diameter of described guide pin bushing frock 5 bellmouth is 240 millimeters.Described guide pin bushing frock 5 height is 100 millimeters.
