The piston pin remover of a diesel locomotive comprises a tray (1), an air cylinder (2), a reset spring (3) and a push rod (4), wherein the tray (1) is a trough-type structure formed by two vertical plates and a transverse plate; the lower ends of two vertical plates of the tray (1) are connected as a whole through the transverse plate; a vertical plate I in the tray is connected to the lower part at one end of the air cylinder (2); the air cylinder (2) is in a cylindrical structure; round holes through which the push rod (4) extends are formed at one end of the air cylinder (2) connected with the tray (1); the other end of the air cylinder (2) is communicated with an air pipe; and the push rod (4) is positioned in the air cylinder (2). By the remover, the piston pin in a piston linkage of the diesel locomotive can be removed conveniently and rapidly, the equipment investment and manual labor are reduced, and the working efficiency for repairing a diesel engine is improved.
Description
Technical field
The utility model belongs to pincers worker flight-line maintenance technical field, relates generally to a kind of diesel engine of diesel locomotive piston pin remover.
Background technology
The piston rod group is one of moving component important in the diesel engine of diesel locomotive, by piston pin connecting rod and piston is coupled together, and connecting rod changes the straight reciprocating motion of piston the gyration of bent axle into, and between piston and bent axle transfer function power; Being matched in clearance between the lining of piston pin and wrist-pin hole, is interference fits between the pin-and-hole of piston pin and piston.During the piston rod assembling, with baking oven piston is heated to 100 ~ 120 ℃, small end of connecting rod is placed in the piston, then piston pin is assembled in the piston boss hole.
In the diesel engine overhaul, piston pin must be removed from piston and renewed.Because piston rod group physical dimension is very large, adopt heating to remove so can not adopt freezing dismounting method; Adopt heating to remove the increase that can bring again equipment and the amount of labour; Owing to be interference fits between the pin-and-hole of piston pin and piston, have certain frictional force in addition, it is very large to remove labour intensity with the common machinery method of knocking.
The utility model content
For solving the problems of the technologies described above, the purpose of this utility model is to propose a kind of diesel engine of diesel locomotive piston pin remover, can remove quickly and easily the piston pin in the diesel engine of diesel locomotive piston rod group, reduce equipment investment and hand labor amount, improve the operating efficiency of repairing diesel engine.
The utility model is to finish the technical scheme that the foregoing invention task takes to be: a kind of diesel engine of diesel locomotive piston pin remover, and described piston pin remover includes pallet, reservoir, back-moving spring and push rod; Described pallet is by two risers and the trench structure that transverse slat consists of; Two riser lower ends of described pallet are connected as a single entity by transverse slat; Riser I in the described pallet is connected to the bottom of reservoir one end; Consist of the space in order to the piston of placing required dismounting between the end face that described reservoir is connected with pallet and the riser II in the pallet; Described reservoir is cylinder-like structure, and the end that described reservoir is connected with pallet has the circular hole that stretches out in order to push rod, and the other end of described reservoir is connected with airduct; Described push rod is positioned at described reservoir, and described push rod is under Action of Wind pressure, to stretch out the structure that reservoir is removed the piston pin of required dismounting; Described back-moving spring is nested with on push rod.
Has the through hole that passes in order to piston pin on the riser II in the described pallet.
The end that described reservoir is communicated with airduct has the circular hole that is communicated with airduct.
Described push rod is the rod shaped structure that an end has disk; And the diameter of disk is less than the internal diameter of reservoir on the push rod.
A kind of diesel engine of diesel locomotive piston pin remover that the utility model proposes, adopt technique scheme, can remove quickly and easily the piston pin in the diesel engine of diesel locomotive piston rod group, reduce equipment investment and hand labor amount, improve the operating efficiency of repairing diesel engine.
