Description

Technical Field

[0001] This utility model relates to the field of water-cooled motor housing technology, and in particular to a water-cooled motor housing sealing testing device. Background Technology

[0002] The housing of a water-cooled motor is the component that encloses the motor and carries coolant inside to dissipate heat. Poor sealing and leakage can lead to heat dissipation failure and may also cause short circuits or damage to the motor. To ensure the normal operation of the motor, a sealing test is required.

[0003] The prior art, such as the motor housing sealing performance testing device disclosed in announcement number CN222166444U, includes a support frame and a water tank disposed inside the support frame; a hydraulic cylinder fixedly installed on the top wall of the support frame, a moving rod fixedly installed on the output end of the hydraulic cylinder, a pressure plate fixedly installed on the bottom wall of the moving rod, an exhaust hole opened on the bottom wall of the pressure plate, and an air pump fixedly installed on the inner top wall of the support frame, with an air pipe fixedly installed on the output end of the air pump.

[0004] However, this technical solution has the following problems in practical use: A sleeve with an open slot (bottom of the side wall) passes through the support plate, and an air pipe with an air outlet (side wall) passes through the sleeve with the hole aligned with the slot. After water comes out of the motor housing, the air pump sends air from the open slot into the outer slot to dry the water droplets on its outer wall. However, because the air pipe is located inside the sleeve, and due to the characteristics of its corrugated hose, there is a lack of a structure to ensure that the air outlet and the open slot are aligned. The hose is easily squeezed inside the sleeve, and the two cannot be completely aligned, which will directly affect the subsequent drying efficiency. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art where the air pipe is set inside the sleeve, and due to the characteristics of its corrugated hose, there is a lack of structure to ensure that the air outlet and the opening groove are aligned, and the hose is easily squeezed inside the sleeve, making it impossible for the two to be completely aligned. Therefore, this invention proposes a water-cooled motor housing sealing test device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A water-cooled motor housing sealing testing device includes a mounting base, a water immersion part disposed on the mounting base, a cylinder fixedly disposed on the mounting base, a pressure seat fixedly disposed at the bottom output end of the cylinder, and an air pump for supplying air to the pressure seat. The pressure seat has a fixedly disposed air chamber, and four air blocking plates are horizontally slidably disposed on the top of the air chamber. The inner cavity of the pressure seat is divided into a temporary storage chamber one and a temporary storage chamber two by the four air blocking plates connected end to end. The device also includes: A drive assembly is disposed within the pressure base and is used to drive the four air baffles to slide horizontally synchronously.

[0007] Preferably, the driving component includes: Rotary rod, which is rotatably connected to the top surface of the gas chamber; The motor is fixedly connected inside the pressure base and is used to drive the rotating rod to rotate. The rotating seat is fixedly sleeved on the rotating rod.

[0008] Preferably, the driving component further includes: Connecting ears, a pair of connecting ears are fixedly connected to the opposite side walls of the rotating base and the air baffle plate; A connecting shaft is fixedly connected to the opposite sidewalls of the two connecting ears; The traction rod is rotatably sleeved on the connecting shaft.

[0009] Preferably, the top of the gas chamber is provided with a groove corresponding to the gas barrier plate, and a connecting plate is horizontally slidably connected in the groove, and the connecting plate and the gas barrier plate are fixedly connected.

[0010] Preferably, the air chamber is provided with a plurality of air vents, and the air vents are located on opposite sides of the four air baffles.

[0011] Preferably, four connecting plates are fixedly connected to the opposite side walls of the gas chamber and the pressure base.

[0012] Compared with the prior art, the advantages of this utility model are as follows: This invention, through the setting of components such as the drive assembly and the air baffle, allows the pressure seat to be reset after the housing is reset. The starting motor drives the rotating rod to rotate, and the rotating seat rotates synchronously. The air baffle is pulled through the connecting lug, connecting shaft and traction rod, connecting the first temporary storage chamber and the second temporary storage chamber. When the air pump supplies air, the gas enters the housing through the vent and is blown to the outside of the housing through the second temporary storage chamber to dry. At the same time, it prevents the gas from leaking from other gaps, forming an effective airflow, which effectively ensures the efficiency of drying the housing and testing.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figures 1-3 A water-cooled motor housing sealing testing device includes a mounting base 1, a water-immersing part 2 disposed on the mounting base 1, a cylinder 3 fixedly disposed on the mounting base 1, a pressure seat 4 fixedly disposed at the bottom output end of the cylinder 3, and an air pump 5 for supplying air to the pressure seat 4. The water-immersing part 2 includes components such as a spring and a water tank, and it, along with the cylinder 3 and the air pump 5, are all existing mature technologies, so they will not be described in detail here. It should be added that the hose connected to the air pump 5 is connected to a temporary storage chamber 10, and the gas pumped by the air pump 5 enters the temporary storage chamber 10. A gas chamber 6 is fixedly installed inside the pressure base 4. Four gas baffles 8 are horizontally slidably installed on the top of the gas chamber 6. The inner cavity of the pressure base 4 is divided into a first storage chamber 10 and a second storage chamber 11 by the four gas baffles 8 connected end to end. The four gas baffles 8 can separate the first storage chamber 10 and the second storage chamber 11 through synchronous operation. Its advantage is that it can flexibly adjust the gas isolation state of the first storage chamber 10 and the second storage chamber 11, realizing the switching and control of the gas passage. The coordinated operation of the four gas baffles 8 can ensure the uniformity of the separation boundary and avoid gas crossflow caused by local poor sealing. It provides an effective switching guarantee for the gas pressure control in the detection stage and the airflow control in the drying stage. It also includes; The drive assembly is located inside the pressure base 4 and is used to drive the four air baffles 8 to slide horizontally synchronously.

[0017] Reference Figures 2-3 The drive components include: a rotating rod 82, a motor 81, and a rotating base 83.

[0018] The rotating rod 82 is rotatably connected to the top surface of the air chamber 6; the motor 81 is fixedly connected inside the pressure seat 4, and the motor 81 is used to drive the rotating rod 82 to rotate; the rotating seat 83 is fixedly sleeved on the rotating rod 82. The motor 81 provides stable power output, and the rotating rod 82 and the rotating seat 83 convert the rotational motion into linear traction power. With the linkage structure formed by the connecting ear 84, the connecting shaft 85 and the traction rod 86, it can drive the four air baffles 8 to slide horizontally synchronously, so as to realize the switching between drying and detection states and ensure the synchronicity of the adjustment of the air baffles 8.

[0019] The drive assembly also includes: a connecting ear 84, a connecting shaft 85, and a traction rod 86.

[0020] A pair of connecting ears 84 are fixedly connected to the opposite side walls of the rotating seat 83 and the air baffle 8; the connecting shaft 85 is fixedly connected to the opposite side walls of the two connecting ears 84; the traction rod 86 is rotatably sleeved on the connecting shaft 85.

[0021] The top of the gas chamber 6 has a groove 87 corresponding to the air baffle plate 8. A connecting plate 88 is horizontally slidably connected within the groove 87, and the connecting plate 88 and the air baffle plate 8 are fixedly connected. The groove 87 and the connecting plate 88 ensure that the air baffle plate 8 slides stably and horizontally.

[0022] The gas chamber 6 has several vent holes 9, which are located on opposite sides of the four air baffles 8. The distribution of the vent holes 9 allows the gas in the gas chamber to enter the motor housing under test evenly and stably through the vent holes 9, avoiding the problem of uneven air pressure caused by local gas accumulation.

[0023] Four connecting plates 7 are fixedly connected to the opposite side walls of the gas chamber 6 and the pressure base 4.

[0024] The functional principle of this utility model can be explained through the following operation methods: Preparation stage: Place the water-cooled motor housing to be tested stably in the immersion part 2 of the mounting base 1, ensuring that the opening of the housing faces upward and that there are no foreign objects on the contact surface with the subsequent pressure base 4. Fixed sealing: Start the cylinder 3 fixed on the mounting base 1. The bottom output end of the cylinder 3 drives the pressure base 4 to descend vertically until the pressure base 4 is completely in contact with the top opening of the motor housing (the air chamber 6 is fixed to the pressure base 4 through the connecting plate 7 to ensure structural stability when in contact), thus achieving housing sealing. Gas supply initialization: Turn on the air pump 5. The air pump 5 delivers gas into the pressure base 4. The gas first enters the temporary storage chamber 10 and the fixed gas container 6 in the pressure base 4 in sequence. At this time, the temporary storage chamber 10 and the temporary storage chamber 2 11 in the gas container 6 are separated by four air baffles 8 and are in the initial volume state. Sealing test: Gas in the gas chamber 6 is continuously blown into the motor housing through the vent holes 9 located on opposite sides of the four air baffles 8; observe the liquid in the immersion section 2. If no bubbles are generated, the housing is sealed successfully; if bubbles are generated, it indicates that there is a leak in the housing and the seal is unsuccessful. After the test, the cylinder 3 is reverse-started to reset the pressure seat 4. Air drying housing: After the pressure seat 4 and the housing are reset, the motor 81 of the drive assembly is started. The motor 81 drives the rotating rod 82 to rotate on the top surface of the gas chamber 6. The rotating seat 83 fixedly sleeved on the rotating rod 82 rotates synchronously. The rotating seat 83 is connected to the traction rod 86 through a pair of connecting ears 84 and connecting shaft 85. When the rotating seat 83 rotates, the traction rod 86 pulls the air blocking plate 8. The air blocking plate 8 drives the connecting plate 88 to slide horizontally in the sliding groove 87 at the top of the gas chamber 6. The four air blocking plates 8 move away from each other synchronously, so that the first temporary storage chamber 10 and the second temporary storage chamber 11 are connected. After the first temporary storage chamber 10 and the second temporary storage chamber 11 are connected, the air pump 5 delivers gas to the pressure seat 4. The gas is not only continuously blown into the housing through the vent hole 9 on the container 6, but also blown to the outside of the housing through the second temporary storage chamber 11 for air drying, ensuring the efficiency of air drying.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
