Description
Technical field
The utility model relates to a kind of dismantling device, is specifically related to a kind of diesel engine of diesel locomotive valve-spring tool.
Background technology
Diesel locomotive used after a period of time, and diesel engine power declines to some extent, burns insufficient, and fuel oil expends greatly, and with the compression pressure of Pressure gauge test diesel engine, lower than compression pressure 4MPa manufacturing etc., these phenomenons show that diesel engine work cylinder must overhaul.In maintenance process, need to dismantle valve spring, will first compression valve spring, could take out locker, because the elastic force of valve spring is very large, so be difficult to dismounting valve spring with general instrument.At present, common method for dismounting is that it is placed under forcing press, will after valve spring compression, dismantle, but diesel engine is large and heavy, is unfavorable for carrying with forcing press again.
Now, also have some simple dismantling devices can directly take field operation to, but these dismantling devices all need operating personnel dismantling device to be exerted pressure on one side in operating process, with hand reach locker on one side, have certain danger, and operating personnel relatively require great effort.
Utility model content
For above-mentioned deficiency, it is a kind of simple in structure that the utility model provides, labour-saving easy to use diesel engine valve spring dismantling device.
To achieve these goals, the technical solution adopted in the utility model is:
A diesel engine valve spring dismantling device, comprises bearing, and the two ends of this bearing are provided with the fixture fixing with cylinder head fixing stud, on described bearing, is connected with connector, and this connector coordinates with screw flight, and the bottom of this screw rod is connected with pressure head; Described fixture comprises fixing hole, and this fixing hole internal clearance is combined with sleeve, and this sleeve is provided with internal thread, and the top of described sleeve is provided with fixing hole is fixed on to the snap ring on cylinder head fixing stud; The top of described screw rod is connected with dwang.
The beneficial effects of the utility model are:
The utility model is simple in structure, easy to use, laborsaving, safety, and with low cost, easily safeguard.
Described fixture is provided with sleeve, and this sleeve is provided with the internal thread matching with cylinder head fixing stud, has facilitated the dismounting of bearing and cylinder head fixing stud.
The top of described screw rod is connected with dwang, can facilitate, labour-saving rotating screw bolt.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A-A face cutaway view of Fig. 1.
The specific embodiment
As shown in the figure, a kind of diesel engine valve spring dismantling device, comprise bearing 1, the two ends of this bearing 1 are provided with the fixture fixing with cylinder head fixing stud 2, this fixture 2 includes fixing hole, and fixing hole internal clearance is combined with sleeve 7, and described sleeve 7 is provided with internal thread, the external screw thread of this internal thread and cylinder head fixing stud is suitable, and the top of described sleeve 7 is provided with fixing hole is fixed on to the snap ring 8 on cylinder head fixing stud; On described bearing 1, be connected with connector 4, at the middle part of bearing 1, be provided with through hole, one end of described connector 4 is connected with screw rod, and this screw rod links together connector 4 and bearing 1 through through hole and by nut, and connector 4 can rotate on bearing 1; The other end of described connector 4 is provided with internal thread, on this internal thread, be combined with screw rod 5, the bottom of this screw rod 5 is connected with pressure head 3, this pressure head 3 coordinates the bottom that is arranged on screw rod 5 with packing ring by nut, described pressure head 3 can rotate in screw rod 5 bottoms, the bottom of described pressure head 3 is provided with the circular hole for the turnover of spring locker, and the middle part of pressure head 3 is provided with the spatial accommodation of getting dress locker for staff; The top of described screw rod 5 is provided with through hole, and dwang 6 is connected with screw rod 5 through through hole, for rotary screw 5.
The utility model use procedure is as follows:
When needs are dismantled valve spring, first according to the position of valve spring, on cylinder cap, select suitable cylinder head fixing stud, then bearing 1 is fixed on cylinder head fixing stud by sleeve 7, then rotating connector 4 makes pressure head 3 over against valve spring upper seat top, then by dwang 6 rotary screws 5, pressure head 3 is pressed down valve spring, in the time of until spring locker arrives pressure head 3 through pressure head 3 in the middle of, staff takes off its locker, then opposite spin screw rod 5, and spring and the spring seat of honour can be deviate from; When needs are installed valve spring, spring and the spring seat of honour are put well successively, utilize the utility model that valve spring is compressed, then locker is installed, finally by sleeve 7, the utility model is unloaded and can complete dismounting from cylinder head fixing stud.
The utility model is simple in structure, easy to use, laborsaving, safety, and with low cost, easily safeguard.
