Detailed Description

The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form a part hereof, and which together with the embodiments of the invention serve to explain the principles of the invention.

Example one

The embodiment provides a detection device for motor intake, refer to fig. 1 to 6, including surge tank 1, roof 2, push pipe 3 and motor assembly pipe 4, the one end of push pipe 3 passes through roof 2 and surge tank 1 fixed connection, the other end cover of push pipe 3 locates the outside of motor assembly pipe 4 and can dismantle, sealed tight fit with motor assembly pipe 4, surge tank 1 places on laboratory bench or subaerial through support 6.

When the air intake of the motor is detected, the motor 7 can be placed in the motor assembly pipe 4 for component detection; when the intake of the motors 7 of different models is detected, the original motor assembling pipe 4 is firstly detached from the top pipe 3, and then a new motor assembling pipe 4 is inserted into the top pipe 3, so that the replacement of the motor assembling pipe 4 is completed.

Compared with the prior art, in the detection device of the motor intake that this embodiment provided, the volume of motor assembly pipe 4 is less than the total volume of roof 2 and push pipe 3 far away, when detecting the intake of different model motors, only need with wait to detect the motor assembly pipe 4 body that the motor is the same of motor assembly pipe 4 assembly on push pipe 3 can, need not change roof 2 and push pipe 3 to change time has been reduced by a wide margin, has reduced the motor intake effectively and has detected the degree of difficulty.

As for the structure of the motor assembling pipe 4, specifically, it may include an internal pipe body 41 and an external pipe body 42 connected to the internal pipe body 41, the internal pipe body 41 is inserted into the top pipe 3 and is hermetically connected to the top pipe 3, the external pipe body is located outside the top pipe 3, and the motor 7 is erected in the external pipe body 42. The motor assembling pipe 4 adopts the structure, the internal pipe body 41 is used for being connected with the top pipe 3 in a sealing mode, and the external pipe body 42 can be used as a handheld part when the motor assembling pipe 4 is replaced, so that the motor assembling pipe 4 can be conveniently detached from the top pipe 3.

In order to prevent the external pipe 42 from being inserted into the top pipe 3, a stopper ring (not shown) for axially stopping the external pipe 42 may be provided at a joint between the external pipe 42 and the internal pipe 41. After the internal pipe body 41 is inserted into the top pipe 3, if the external pipe body 42 is continuously pressed, the limiting ring can abut against the top pipe 3 of the top pipe 3 to axially limit the external pipe body 42, so that the external pipe body 42 can be prevented from being further downwards inserted into the top pipe 3.

For the axial limitation of the external pipe 42, the diameter of the external pipe 42 may be larger than that of the internal pipe 41. Therefore, the connection part of the external pipe body 42 and the internal pipe body 41 can also form a limiting bulge similar to a limiting ring, and the external pipe body 42 is axially limited by the limiting bulge.

In order to realize the sealing connection between the inner pipe body 41 and the top pipe 3, a plurality of sealing rings 43 may be arranged between the inner pipe body 41 and the top pipe 3, the sealing rings 43 are sleeved outside the inner pipe body 41, the number of the sealing rings 43 is plural, the plurality of sealing rings 43 are arranged along the axial direction of the inner pipe body 41, and the plurality of sealing rings 43 act together, so that the sealing connection between the inner pipe body 41 and the top pipe 3 can be realized.

it can be understood that, in the process of mounting and dismounting the built-in pipe body 41, in order to reduce the axial displacement of the built-in pipe body 41, a clamping groove is formed in the outer side of the built-in pipe body 41 along the circumferential direction, the sealing ring 43 is located in the clamping groove, and the sealing ring 43 corresponds to the clamping groove one to one. The sealing ring 43 is arranged in the clamping groove, the side wall of the clamping groove can axially limit the sealing ring 43, and axial displacement in the installation and disassembly processes of the built-in pipe body 41 is reduced, so that the stability of sealing connection between the built-in pipe body 41 and the top pipe 3 is further improved.

In order to prevent the sealing ring 43 from being separated from the clamping groove under the action of force in the process of connecting the built-in pipe body 41 and the top pipe 3, an elastic retainer ring 45 can be arranged in the clamping groove. Illustratively, the number of the elastic check rings 45 in one card slot is 1 to 2. When the number of the elastic check rings 45 is 1, the elastic check rings 45 are positioned on one side of the clamping groove close to the pressure stabilizing box 1; when the number of the elastic check rings 45 is 2, the elastic check rings 45 are positioned on two sides of the mounting groove, and the sealing ring 43 is positioned between the two elastic check rings 45.

Likewise, in order to ensure the installation stability of the motor 7, an elastic support ring 44 may be provided on the inner wall of the outer tube 42, and it should be noted that the elastic support ring 44 has substantially the same structure as the sealing ring 43. The motor 7 is erected in the external pipe body 42 through the elastic support ring 44, and the elastic support ring 44 can radially limit the motor 7, so that the installation stability of the motor 7 can be improved.

In order to further improve the installation stability of the motor 7 during detection, the detection device for the motor intake air amount can further comprise a limiting flange 5 for limiting the axis of the motor 7, and the limiting flange 5 is sleeved at the top end of the motor assembly pipe 4. Like this, the elastic support ring 44 can carry out radial spacing to the motor 7, and the limiting flange 5 can carry out axial spacing to the motor 7, and both mutually support for the inside of external body 42 is arranged in steadily at the testing process to the motor 7, has improved the detection precision of the detection device of motor intake.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the present invention.
