Description

Technical Field

[0001] This application relates to the technical field of motor housing airtightness detection, and particularly to a quick-clamping auxiliary tooling for motor airtightness detection. Background Art

[0002] Figure 1 For a half shell 1 of a motor housing, a plurality of water holes, wire holes and controller holes are provided on its side wall. These holes have irregular shapes and relatively thin wall thicknesses, and it is difficult to fix the existing plugs for inflation detection.

[0003] A Chinese utility model patent with the name of an auxiliary tooling for motor airtightness detection was previously applied. It includes an inflation fixture and a plugging fixture. Both the inflation fixture and the plugging fixture include a cylinder barrel, a locking rod, a tail plug and an adjusting screw. The tail plug is fixed at the end of the cylinder barrel, and the adjusting screw is rotatably connected to the tail plug. It is blocked on the motor housing by pulling with a locking tongue and the cylinder barrel, and has a good plugging effect, is not easily affected by the hole shape and thickness, and greatly improves the efficiency of motor airtightness detection.

[0004] However, in the actual use process, by turning the adjusting screw to pull the locking rod to lock on the housing, due to the large number of holes, it takes a long time, the labor intensity of the staff is high, and the production efficiency is low. Therefore, our company has made improvements on this basis. Summary of the Utility Model

[0018] The following is combined with the attachedFigures 2-4 A further detailed description of the present application will be given.

[0019] The embodiment of the present application discloses a quick-clamping auxiliary tooling for motor airtightness detection. Referring to Figures 2-4 , it includes an inflation clamp 2 and a plugging clamp 3. Both the inflation clamp 2 and the plugging clamp 3 include a cylinder 21, a locking rod 22 and a quick-clamping mechanism 23. The locking rod 22 is movably arranged in the cylinder 21. The outer diameter of the locking rod 22 is smaller than the inner diameter of the cylinder 21. A plurality of sealing rings 221 are fixedly sleeved on the surface of the locking rod 22. The sealing rings 221 can abut against the inner wall of the cylinder 21. The quick-clamping mechanism 23 can provide the function of quickly positioning the locking rod 22. One end of the locking rod 22 away from the quick-clamping mechanism 23 has a lock head. The lock head includes a connecting rod 222 and a lock tongue 223. The outer diameter of the connecting rod 222 is smaller than the outer diameter of the locking rod 22. The lock tongue 223 is fixed at the end of the connecting rod 222. An air inlet hole is opened on the surface of the cylinder 21 in the inflation clamp 2. The air inlet hole is arranged at one end away from the quick-clamping mechanism 23. An air inlet quick connector 24 is installed at the air inlet hole. A sealing gasket 25 is fixed at the end of the cylinder 21 close to the lock head.

[0020] Referring to Figure 2 and Figure 3 , the quick-clamping mechanism 23 includes a tail plug 231, a push rod 232, a transmission member 233 and a driving member 234. The tail plug 231 is fixed on the cylinder 21. The push rod 232 is movably connected in the tail plug 231 and is fixed to the locking rod 22. The transmission member 233 is hinged to the tail plug 231 through a first hinge point 4. The driving member 234 is hinged to the transmission member 233 through a second hinge point 5. The driving member 234 has a driving part 2341 perpendicular to the driving member 234. The driving part 2341 is arranged inside the transmission member 233. The driving part 2341 is hinged to the push rod 232 through a third hinge point 6. The transmission member 233 has a limit link 2331. The limit link 2331 is arranged at the bottom ends of the push rod 232 and the driving part 2341.

[0022] The implementation principle of the quick-clamping auxiliary tooling for motor airtightness detection in the embodiment of the present application is as follows:

[0023] The staff uses an inflation clamp 2 and multiple blocking clamps 3 to seal all the holes on the motor housing. When blocking, the staff passes the locking tongue 223 in the inflation clamp 2 and the blocking clamp 3 into the hole, holds the cylinder 21 with one hand, and uses the other hand to pry the driving member 234 outward. The driving member 234 pulls the push rod 232, and the push rod 232 drives the locking rod 22 to move, so that the locking tongue 223 and the cylinder 21 are clamped on the wall of the motor housing. After that, high-pressure air is filled into the motor housing through the air inlet quick connector 24 in the inflation clamp 2 and the pressure is maintained, which makes detection more convenient.

[0024] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
