3 test macro of engine is aided in illustrating.
Embodiment 2
Please refer to Fig. 1-Figure 14.The present invention provides a kind of 3 test macros of engine.This 3 test macro packet of engine
Include Engine Block Test support frame 1 and moment transmitting device 2.
When carrying out the test of engine 3, Engine Block Test support frame 1 provided by the invention is used to support engine 3.Torque
Transfer device 2 is used to the output torque of loading device passing to engine 3, so that engine 3 can be in certain resistance
It works under the action of torque.
Specifically, Engine Block Test support frame 1 includes bottom plate 11, resilient cushion 12, support rod 13, vertical loading board 14 and exhaust pipe
16.The quantity of support rod 13 is four.The quantity of vertical loading board 14 is two.
Resilient cushion 12 is set on bottom plate 11, is connected between 13 one end of support rod and bottom plate 11 by resilient cushion 12.Support rod
13 other ends are equipped with sliding slot 132.
Vertical loading board 14 is equipped with the first tight lock part 142 being adapted to sliding slot 132.First tight lock part 142 is set on annular groove
Structure.The setting of first tight lock part 142, so that size of the vertical loading board 14 at the first tight lock part 142 is less than the ruler of sliding slot 132
It is very little, and size of the vertical loading board 14 in 142 two sides of the first tight lock part is greater than the size of sliding slot 132.14 one end of vertical loading board is equipped with first
Tight lock part 142,14 other end of vertical loading board are equipped with the first tight lock part 142.When in use, vertical loading board 14 is connected with for engine 3,
Specifically, please referring to Figure 14, engine 3 is equipped with the hole cooperated with vertical loading board 14, and vertical loading board 14 passes through the hole.On vertical loading board 14
The first tight lock part 142 cooperate with sliding slot 132, and the size due to vertical loading board 14 in 142 two sides of the first tight lock part is greater than sliding slot
132 size, therefore, vertical loading board 14 can not generate displacement on the length direction of vertical loading board 14, so that engine 3 is being hung
It fills and is fixed on the length direction of bar 14.
It further include the second tight lock part 15 on support rod 13.Second tight lock part 15 is fast clip, model DE-STA-CO company
3051 serial fast clips.Specifically, the second locking includes that folder hooks 151, lever and fixed part.Wherein, fixed part is fixedly connected
In on support rod 13.Folder hooks 151 to be slidably connected with fixed part, and 151 other ends of folder hook can be with the lifting that is placed in sliding slot 132
Bar 14 connects.Operation portion 152 and fixed part are hinged, and folder hooks 151 one end far from vertical loading board 14 and is connected with operation portion 152.It is fixed
Portion is equipped with the clamping portion being clamped with operation portion 152, when operation portion 152 is in angle with support rod 13, operation portion 152 and clamping
Part is from folder hooks 151 and can be detached from from vertical loading board 14.When operation portion 152 is bonded with support rod 13, operation portion 152 and card
Socket part clamping, folder hook 151 clamping vertical loading boards 14, so that the position of vertical loading board 14 is fixed in the short transverse of support rod 13.
The depth direction of sliding slot 132 is used to be consistent with the exhaust outlet direction of engine 3.The height of exhaust pipe 16 is in this way
Be arranged: when vertical loading board 14 along the chute 132 slide into the bottom of sliding slot 132 when, one end of exhaust outlet and the exhaust outlet phase of engine 3
Even.Specifically, setting first is in charge of 162 and second and is in charge of 164 on exhaust pipe 16, first, which is in charge of 162, second, is in charge of 164 and sets
It sets, so that exhaust pipe 16 is at y-type structure.First, which is in charge of 162 one end, is in charge of 164 one end with second and is connected.First to be in charge of 162 another
The end at end is equipped with spherical surface tube head 166, and the second end for being in charge of 164 other ends is equipped with spherical surface tube head 166.
Spherical surface tube head 166 is the spherical shell structure of both ends perforation, and one end that spherical surface tube head 166 is relatively large in diameter is used for and first point
Pipe 162 or the second is in charge of 164 and is connected.
Since the direction of sliding slot 132 and the direction of 3 exhaust outlet of engine are consistent, when vertical loading board 14 132 is slided along the chute
When moving to the bottom of sliding slot 132, spherical surface tube head 166 can cooperate with the exhaust outlet of engine 3 and be connected.Spherical surface tube head 166 with
During the exhaust outlet of engine 3 is connected, exhaust outlet of the lesser one end of the diameter of spherical surface tube head 166 first with engine 3
It is in contact, is easy to that spherical surface tube head 166 is made to enter 3 exhaust outlet of engine.Then as stepping into for spherical surface tube head 166, spherical surface
Gap between tube head 166 and the exhaust outlet of engine 3 gradually becomes smaller, until the outer wall and engine 3 of spherical surface tube head 166 are vented
Mouthful inner wall between generate abutting, realize spherical surface tube head 166 with started being connected between exhaust outlet.During the test, it sends out
Motivation 3 may generate a series of vibration, since spherical surface tube head 166 is partly or entirely placed in exhaust outlet, this
Kind structure can resist a degree of vibration, and making will not be since test be shaken between spherical surface tube head 166 and the exhaust outlet of engine 3
It moves and separates.
In conclusion making vertical loading board 14 and engine first when using Engine Block Test support frame 1 provided by the invention
3 are connected, specifically, the hole for being adapted to vertical loading board 14 can be arranged on engine 3.Then by engine 3 and vertical loading board
14 are lifted into the top of the Engine Block Test support frame 1, enter the first tight lock part 142 on vertical loading board 14 in sliding slot 132, so
Engine 3 132 will slide along the chute together with vertical loading board 14 afterwards, when sliding into 132 bottom of sliding slot, the exhaust outlet of engine 3 with
The cooperation of spherical surface tube head 166 on exhaust pipe 16 is connected, and locks the second tight lock part 15.At this point, engine 3 is high in support rod 13
Displacement on degree direction is limited by the second tight lock part 15, and displacement of the engine 3 on the length direction of vertical loading board 14 is by the first lock
Tight portion 142 and the cooperation of sliding slot 132 limit, so that the position of engine 3 is fixed.After engine 3 is fixed, sending out
Loading moment is tested in motivation 3.
