Description

Technical Field

[0001] This utility model relates to the technical field of quality inspection devices for automotive parts, and in particular to a comprehensive positioning and inspection device for automotive electronic water pumps. Background Technology

[0002] As a key component of automotive thermal management systems, electric water pumps are widely used in areas such as power battery cooling, turbocharger cooling circuits, and heat pump systems. The installation accuracy of their inlet, outlet, and motor housing directly affects the assembly effect and heat dissipation efficiency of the engine or battery.

[0003] Before the electric water pump is produced, the assembly position needs to be checked to ensure the quality of subsequent assembly and avoid the interface position from affecting the normal assembly of the engine. Since the water inlet and water outlet of the electric water pump are usually located on different planes, traditional measuring tools are difficult to accurately determine the position deviation.

[0004] Currently, the industry generally uses coordinate measuring machines for inspection. Although they are highly accurate, they are time-consuming and costly, which cannot meet the needs of mass production. Therefore, there is an urgent need for a dedicated device that is efficient, low-cost, and suitable for batch inspection. Summary of the Invention

[0005] This utility model addresses the problems mentioned in the background art by providing a comprehensive positioning and testing device for automotive electronic water pumps, which improves the efficiency of assembly position detection in the mass production of electronic water pumps, and has low testing cost and high efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An integrated positioning and testing device for an electronic water pump, characterized by comprising a base plate, a housing positioning platform, an outlet testing platform, and an inlet testing platform;

[0008] The shell positioning platform is set on the upper surface of one side of the base plate, and the outlet detection platform is set on the upper surface of the other side of the base plate opposite to the shell positioning platform. The inlet detection platform is set on the upper surface of the base plate on one side between the shell positioning platform and the outlet detection platform.

[0009] The upper surface of each end of the housing positioning platform is provided with a boss. Each boss is provided with 1-2 fixing bolt holes according to the fixing point on the housing of the electronic water pump. The bottom plate of the housing positioning platform between the two bosses is provided with several bolt through holes for fixing to the bottom plate by bolts.

[0010] The outlet detection platform includes a base A, a detection rod A, and a limiting ring A. The base A has a protruding plate perpendicular to the base A. The upper side of the protruding plate has a through hole aligned with the outlet of the electronic water pump. The detection rod A is a cylinder with two sections of different diameters. The larger end of the detection rod A passes through the through hole of the base A and can extend and retract axially and is aligned with the outlet of the electronic water pump. The limiting ring A is provided at the transition between the larger and smaller ends of the detection rod A to limit the radial position of the detection rod A.

[0011] The inlet testing platform includes a base B, a testing rod mounting base, a testing rod B, and a limiting ring B. The base B has a protruding post perpendicular to the base B. The top of the protruding post has an inclined surface with an angle set according to the position of the inlet of the electronic water pump, and the inclined surface faces the testing rod A. The testing rod mounting base is detachably fixed to the inclined surface of the protruding post. The longitudinal section of the testing rod mounting base is an L-shaped right-angled metal block. The upper side of the testing rod mounting base has a through hole aligned with the inlet of the electronic water pump. The testing rod B has the same structure as the testing rod A. The large end of the testing rod B passes through the through hole of the testing rod mounting base and can extend and retract axially. The limiting ring B is provided at the transition between the large end and the small end of the testing rod B to limit the radial position and axial extension and retraction distance of the testing rod B43.

[0012] To adjust the lateral position of base A and base B, the connection holes between base A and base B and the base plate are oblong holes. A limiting platform and a limiting bolt are provided on one side of the length direction of base A and base B. The limiting platform is rectangular, with a through screw hole on one side of the long side. Corresponding threaded holes are provided on the wide side walls of base A and base B. The limiting bolt passes through the through screw hole on the limiting platform and cooperates with the threaded holes on base A and base B to adjust the lateral position of base A and base B.

[0013] A further aspect of this invention is that, since the inlet positions of different models are at different heights, a gasket of a certain thickness is provided between the inclined surface of the top of the protruding column and the bottom surface of the detection rod mounting base in order to adapt to different models of electronic water pumps.

[0014] A further aspect of this utility model is that, in order to facilitate lifting the bottom plate which has a flat bottom surface, each of the four corners of the bottom surface of the bottom plate is provided with a protruding foot of a certain height.

[0015] A further aspect of this invention is that, for ease of gripping, a U-shaped handle is provided on each of the two upper surfaces of the base plate at a relatively opposite position.

[0016] The working principle of this utility model is as follows: The corresponding fixed legs of the water pump housing of the electronic water pump to be tested are fixed to the fixed bolt holes of the boss on the housing positioning platform by bolts. At this time, the outlet and inlet of the electronic water pump are aligned with the large end of the detection rod of the outlet detection platform and the inlet detection platform, respectively. Then, the aligned detection rod is inserted into the corresponding inlet and outlet. The assembly position of the inlet and outlet of the electronic water pump can be judged according to the smoothness of the insertion of the detection rod.

[0017] The beneficial effects of this utility model are: this device can simultaneously detect the assembly position of the inlet and outlet of the electronic water pump, improve the efficiency of assembly position detection in the mass production of electronic water pumps, and has low detection cost and high efficiency, making it valuable for widespread application.
