Embodiment 1

[0037] Such as Figure 1-5 As shown, in an embodiment of the present invention, a rear cover airtightness detection device for automotive electronic water pump production includes a rotating frame 1, a rectangular airtight detection casing 2 is fixed on the rotary frame 1, and a rectangular airtight detection casing 2 is fixed on the rotary frame 1. 2 There are two long rods 3 symmetrically fixed at the bottom, and the long rod 3 is slidably connected with the automotive electronic water pump rear cover detection component 4, and the bottom end of the automotive electronic water pump rear cover detection component 4 is connected with the inflation mechanism 5, and the automotive electronic water pump rear cover detection component 4 The left end is connected with a pneumatic telescopic mechanism 6, and the pneumatic telescopic mechanism 6 is connected with a casing upper cover sealing structure 7, and a pull ring pretensioning mechanism 8 is arranged on both sides of the casing...

Embodiment 2

[0041] Such as Figure 1-5 As shown, in the embodiment of the present invention, the rotating frame 1 includes a supporting frame 11, and a rotating column 12 is rotatably connected to the supporting frame 11. The rotating column 12 is symmetrically provided with a threaded section 13, and the threaded sections 13 on both sides are respectively covered with left threads. Cover 15 and right threaded cover 16, left threaded cover 15 and right threaded cover 16 are hinged with first articulated frame 17 and second articulated frame 18 respectively, and first articulated frame 17 and second articulated frame 18 are hinged on fixed plate 19, A rotating handle 14 is connected to the right end of the rotating column 12 .

[0042] In the embodiment of the present invention, the rotation effect of the rotating frame 1 is that the handle 14 is manually turned, and then the rotating column 12 rotates, and then the left threaded sleeve 15 and the right threaded sleeve 16 move on the threa...

Embodiment 3

[0044] Such as Figure 1-5 As shown, in the embodiment of the present invention, the hinged positions of the first hinged frame 17 and the second hinged frame 18 on the fixed plate 19 are relative to the edge of the plate, and the threaded sections 13 on both sides of the rotating column 12 are screwed in opposite directions.

[0045] In an embodiment of the present invention, the threaded sections 13 on both sides of the rotating column 12 are screwed in opposite directions so that the left threaded sleeve 15 and the right threaded sleeve 16 keep moving relative to each other when moving, and the first hinged frame 17 and the second hinged frame 18 The hinged position on the fixed plate 19 is the relative position of the edge of the plate, so that the left threaded sleeve 15 and the right threaded sleeve 16 pull the first hinged frame 17 and the second hinged frame 18 when moving, and then the first hinged frame 17 and the second hinged frame It is easier to turn over when th...

Abstract

The invention discloses a rear cover airtightness detection device for automobile electronic water pump production, and belongs to the technical field of automobile electronic water pump rear cover airtightness detection. The rear cover airtightness detection device for automobile electronic water pump production comprises a rotating frame, a rectangular airtightness detection shell is fixed to the rotating frame, an automobile electronic water pump rear cover detection assembly is connected with a long rod in a sliding mode, an inflation mechanism is connected with the bottom end of the automobile electronic water pump rear cover detection assembly, the left end of the automobile electronic water pump rear cover detection assembly is connected with a pneumatic telescopic mechanism, the pneumatic telescopic mechanism is connected with a shell upper cover sealing structure, and pull ring pre-tightening mechanisms are arranged on the two sides of the shell upper cover sealing structure. According to the invention, the airtightness under each pressure effect can be conveniently detected, the detection effect is good, the function of adjusting parameters is realized, the airtightness or water tightness detection can be carried out on two surfaces of a test piece at the same time through positive and negative pressure testing, and the capability of exploring the hidden injury defect is strong.

Description

technical field [0001] The invention relates to the technical field of air tightness detection of the rear cover of an automobile electronic water pump, in particular to an air tightness detection device for the rear cover of an automobile electronic water pump. Background technique [0002] Automotive electronic water pumps, many new energy vehicles, RVs and other special vehicles are often used in miniature water pumps as water circulation, cooling or on-board water supply systems. Such miniature self-priming water pumps are collectively referred to as automotive water pumps. The circular motion of the motor makes the diaphragm inside the pump reciprocate through the mechanical device, thereby compressing and stretching the air in the pump cavity (fixed volume), and under the action of the one-way valve, a positive pressure is formed at the drain (actual output The pressure is related to the power boost received by the pump outlet and the characteristics of the pump); a va...
