Abstract
The utility model provides a disc type exhaust pipe joint for a test bed of a small engine. The disc type exhaust pipe joint comprises a disc, a sealing plate and an exhaust pipe movable joint, wherein the exhaust pipe movable joint is provided with a lug boss corresponding to a lug boss of the disc; the disc, the sealing plate and the exhaust pipe movable joint are connected and assembled together through screw threads on the corresponding lug bosses; a plurality of circular holes of different sizes are formed on the disc and the sealing plate; arrangement of the circular holes can guarantee that, when the disc is pressed against an end face of an exhaust passage opening of a cylinder cover of the engine and is communicated with the exhaust passage opening of the cylinder cover of the engine, only one hole in the disc is communicated with the holes in the sealing plate, and the rest holes in the disc are sealed by the sealing plate; two lug bosses are arranged at the rear end of an exhaust chamber of the exhaust pipe movable joint, counter bores are formed on the lug bosses; a bolt that is screwed to the lug boss on an exhaust pipe base of the corresponding test bed can enable the exhaust pipe movable joint to push the end face of the disc to be pressed against the end face of the exhaust passage opening of the cylinder cover of the engine, thereby realizing sealing. The disc type exhaust pipe joint for the test bed of the small engine disclosed by the utility model is applicable for tests of the test beds of a plurality of engines in different models, and is simple and convenient to operate.
Description
Technical field
The utility model relates to a kind of mini engine test-bed disc type exhaust fitting, can be used for the performance test of multiple different model motor.
Background technique
In engine bench test, often need to adopt exhaust fitting that engine exhaust pipe and power measurer are coupled together, but the exhaust fitting using at present, in the time carrying out different model engine rig test, all will change the exhaust fitting corresponding with this engine model, dismounting is more loaded down with trivial details.
Model utility content
The utility model is a kind of mini engine test-bed disc type exhaust fitting, its technological scheme adopting of dealing with problems is: comprise that disk 2, envelope dish 1, outlet pipe movable joint 3 form, on outlet pipe movable joint 3, be provided with four boss corresponding with disk 2, disk 2, envelope dish 1, outlet pipe movable joint 3 are assembled together by being threaded on corresponding boss.On disk 2, envelope dish 1, have multiple and hole different model engine cylinder cap exhaust road junction corresponding size, and the setting of these circular holes should ensure in the time that disk 2 is pressed against engine cylinder cap exhaust road junction end face and communicate with engine cylinder cap exhaust road junction, on disk 2, only have a hole to communicate with the hole on envelope dish 1, remaining Kong Jun is sealed dish 1 sealing.There are two boss outlet pipe movable joint 3 rear ends, which is provided with counterbore, be screwed into bolt 4 on air vent seat 6 boss of corresponding test-bed and make outlet pipe movable joint 3 promote disk end face to press against engine cylinder cap exhaust road junction end face to realize sealing, the bolt 5 being simultaneously screwed on air vent seat 6 makes it to compress into the groove of outlet pipe movable joint 3 tops, rear ends.
The beneficial effects of the utility model are: only the through hole of disk and corresponding engine cylinder cap exhaust road junction need be connected, by other hole sealings of disk, just can be applicable to the stand test of different model motor with envelope dish.Easy to operation, increase work efficiency.

In figure, 1. envelope dish, 2. disk, 3. outlet pipe movable joint, 4. bolt, 5. bolt, 6. air vent seat.
Embodiment
Disk 2, envelope dish 1, outlet pipe movable joint 3 are assembled together by being threaded on corresponding boss.On disk 2, envelope dish 1, have multiple and circular hole different model engine cylinder cap exhaust road junction corresponding size, when disk 2 is compressed against engine cylinder cap exhaust road junction end face and communicates with engine cylinder cap exhaust road junction, on disk 2, only have a hole to communicate with a hole on envelope dish 1, remaining Kong Jun is sealed dish 1 sealing.
There are two boss outlet pipe movable joint 3 rear ends, which is provided with counterbore, being screwed into bolt 4 on air vent seat 6 boss of corresponding test-bed makes outlet pipe movable joint 3 promote disk 2 end faces to press against engine cylinder cap exhaust road junction end face to realize sealing, the bolt 5 being simultaneously screwed on air vent seat 6 makes it to compress into the groove of outlet pipe movable joint 3 tops, rear end, to fix outlet pipe movable joint 3.
