Description

Technical Field

[0001] This invention relates to the field of water pump testing, and more particularly to an EOL testing device for automotive electronic water pumps. Background Technology

[0002] Inside the engine block of a car, there are multiple water channels for cooling water circulation, connected to the radiator located at the front of the car via water pipes, forming a large water circulation system. A water pump is installed at the upper outlet of the engine, driven by a fan belt, pumping hot water out of the engine block's water channels and pumping in cold water. Next to the water pump is a thermostat. When the car is first started, it does not open, allowing coolant to circulate only within the engine and not through the radiator. Once the engine temperature reaches a certain level, it opens, pumping the hot water into the radiator. The cool air from the moving car blows across the radiator, carrying away heat. Therefore, the performance of the water pump is crucial to the stability of the car's operation. After production, the water pump needs to be tested to ensure its safe and stable performance. Existing testing equipment generally relies on manual sampling, which cannot accurately determine the key parameters and overall performance of the water pump, affecting its later use.

[0033] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0034] Example 1: Please refer to Figure 1 - Figure 6 ,

[0035] The EOL testing equipment for automotive electronic water pumps includes an operating frame 01, which is divided into upper and lower chambers. A control component for controlling the actions of various components is located in the lower chamber of the operating frame 01. An execution component 02 for moving the testing mechanism is located in the upper chamber of the operating frame 01. A clamping mechanism 07 is located on one side of the execution component 02 within the upper chamber of the operating frame 01. The operating frame 01 is an adaptable frame for mounting various internal devices. Multiple threaded holes are provided on its side walls for mounting different devices when necessary. The control component is for human operation; by inputting corresponding commands, the corresponding actions are executed. The clamping mechanism 07 is used to clamp the water pump to be tested. The execution component 02 can move the testing device, connecting it to the water pump for subsequent online testing.

[0036] The clamping mechanism 07 includes a clamping component disposed within the operation frame 01. One side of the clamping component is connected to a second power head 34 and a first power head 33. The actuating end of the clamping component clamps the pump under test 24 located within the operation frame 01, and the pump under test 24 is electrically connected to the first power head 33 and the second power head 34. The bottom of the clamping component is also connected to a replacement component located within the operation frame 01. The clamping component is used to clamp the pump under test 24, placing it in an initially adjustable position to ensure that the pump under test 24 can be connected to the actuating component 02 later. At the same time, the first power head 33 and the second power head 34 can be connected to the pump under test 24 for power supply and internal electrical signal transmission.

[0037] The control components include a PLC controller 03 located in the bottom chamber of the operation frame 01. A memory 15, which is fixedly connected to the operation frame 01, is electrically connected to one side of the PLC controller 03. A safety device 22 is also connected to the bottom of the operation frame 01. A control panel 05 is located in the middle of the operation frame 01, and a display frame 09 is connected to the top of the operation frame 01. Both the control panel 05 and the display frame 09 are electrically connected to the PLC controller 03 via wires. The PLC controller 03 is a programmable PLC that can input and output instructions to drive the corresponding execution component 02 and other electronic devices to work. The memory 15 stores information and instructions, and the display frame 09 displays data to achieve visual output.

[0038] The implementation principle of this application embodiment is as follows: When working, the pump to be tested 24 is placed on the clamping mechanism 07, and then the corresponding plug is connected through the interface to provide power and signal. Then, through the instruction output of the PLC controller 03, the execution component 02 is activated to contact the pump to be tested 24, and then the test is performed. The data is displayed on the display box 09 and stored in the memory 15 for subsequent use.

[0039] Example 2: Combination Figure 1 - Figure 6 This embodiment is an improvement on embodiment 1, further described in the following aspects:

[0040] The execution component 02 includes a translation stage 3 21 fixedly connected to the operation frame 01. The moving end of the translation stage 3 21 is connected to a translation stage 1 13. The moving end of the translation stage 1 13 is connected to a symmetrically arranged connector 1 12. The connector 1 12 is connected to a sensor group 1. The connector 1 12 is connected to one end of the pump under test 24. The translation stage 3 21 can drive the corresponding translation stage 1 13 to move. The translation stage 1 13 drives the connector 1 12 to move. After the connector 1 12 moves, it can also be connected to the output end of the pump under test 24. During the fluid flow process, the sensor group 1 senses and obtains the required data.

[0041] It also includes a support frame 08 connected to the operation frame 01. A second translation stage 20 is connected to the support frame 08, and a second connector 19 is connected to the moving end of the second translation stage 20. A second sensor group is connected to the second connector 19, and a hose is connected to one side of the connector 19. A pressure tank 11 fixedly connected to the operation frame 01 is connected to the other side of the hose. The support frame 08 supports the corresponding second translation stage 20. The moving end of the second translation stage 20 can drive the second connector 19 to descend, thereby connecting it to the input end of the pump under test 24. The high-pressure gas generated by the pressure tank 11 is input into the hose and then further input into the second connector 19 to realize the flow of fluid and test the performance of the water pump under actual conditions.

[0042] The output end of the pressurization tank 11 is connected to a control pipe, which is connected to a hose. A solenoid valve and a flow control valve are connected to the control pipe. The gas in the pressurization tank 11 can be directed to the output through the control pipe, and the flow rate can be controlled by the corresponding solenoid valve and flow control valve to control some fluid variables and ensure the accuracy of the test data.

[0043] The implementation principle of this application embodiment is as follows: through the output of instructions, the translation stage 13 and the translation stage 3 21 are made to work, thereby driving the two connectors 12 to move and contact the output end of the pump under test 24, waiting for the output of the pump under test 24. At the same time, the connector 2 19 moves under the drive of the translation stage 20 and contacts the input end of the pump under test 24. Under the control of the PLC controller 03, the pump under test 24 works by itself or passively forced to work through the output of the pressurization tank 11, and the pump performance is obtained by detecting data through multiple sensors.

[0044] Example 3: Combination Figure 1 - Figure 12 This embodiment is an improvement on embodiment 1, further described in the following aspects:

[0045] The clamping mechanism 07 also includes a sliding groove on the operation frame 01, on which a movable horizontal plate 31 is slidably disposed. The horizontal plate 31 is fixedly connected to the clamping component. A protective box 18 fixedly connected to the operation frame 01 is also provided at the bottom of the horizontal plate 31. The replacement component is located inside the protective box 18. The sliding groove is used as a guide for the movement of the horizontal plate 31. The protective box 18 is used to protect and fix the replacement component to adjust the position of the clamping component.

[0046] The clamping assembly includes a base box 30 fixedly connected to the middle of a horizontal plate 31. A motor 27 is fixedly connected to one side of the horizontal plate 31, and the output end of the motor 27 is driven by a gearbox 29 fixedly connected to the base box 30. The output end of the gearbox 29 is driven by a transversely arranged transmission rod 47. The base box 30 is used to fix the gearbox 29. The motor 27 can output torque, which is then transmitted through the gearbox 29 to drive the corresponding transmission rod 47 to rotate, thereby realizing the transmission of torque and driving the base 43 to rotate. One side of the transmission rod 47 is engaged with a rotatably connected to the horizontal plate 31. The base 43 has a threaded sleeve 46 fitted in the middle, and a moving rod 39 is threadedly connected to the middle of the threaded sleeve 46. During the rotation of the base 43, the moving rod 39 is restrained and cannot rotate, allowing it to move up or down along the threaded sleeve 46. When the moving rod 39 reaches its limit position, it cannot move further. At this point, the threaded sleeve 46 overcomes friction and rotates relative to the base 43, i.e., the threaded sleeve 46 is restricted relative to the horizontal plate 31, thus preventing excessive movement of the moving rod 39. Symmetrically arranged pull rods 44 are rotatably connected to both sides of the moving rod 39. The other end of the pull rod 44 is rotatably connected to a limiting block 40. A fine-tuning ring 45 is rotatably connected to the top of the base box 30, and a lower cover 36 is fixedly connected to the top of the fine-tuning ring 45. An upper cover 32 is snapped onto the lower cover 36. Both the upper cover 32 and the lower cover 36 are provided with a passage groove 41 for the pull rod 44 to pass through. The groove wall of the passage groove 41 on the upper cover 32 slides in contact with the outer wall of the limiting block 40. During the movement of the moving rod 39, due to the limitation between the limiting block 40 and the upper cover 32, and the transmission of force of the pull rod 44, the pull rod 44 moves laterally along the groove wall of the passage groove 41. The upper cover 32 and the tooling 25 move together, thereby achieving the clamping action. The top of the limiting block 40 is threadedly connected to the threaded cover 42, and the two threaded covers 42 are rotatably connected to the tooling 25. The two tooling 25 can approach each other to form a whole. The pump to be tested 24 and the power head 33 are located in the space enclosed by the tooling 25. The base box 30 is connected to a power supply head 35 on one side. During the movement of the upper cover 32, the two tooling 25 are moved closer or further apart, thereby achieving clamping or releasing. The power supply head 35 is used to connect to an external power source to ensure the operation of the clamping mechanism 07.

[0047] A snap-fit ​​groove is provided on one side of the tooling 25. The power head 33 is located in the snap-fit ​​groove on both tooling 25. The tooling 25 is also provided with an adjustment groove for adjusting the threaded cover 42. An adjustment column 37 is threaded onto the moving rod 39. A limiting bolt is connected to the outside of the adjustment column 37, and a flexible column 38 is fixedly connected to the top of the adjustment column 37. When the two tooling 25 approach each other, the power head 33 enters the snap-fit ​​groove, which limits a certain degree of freedom of the corresponding tooling 25 to ensure the stability of the position of the tooling 25. At the same time, by adjusting the length of the adjustment column 37 in the moving rod 39, the initial position of the flexible column 38 is adjusted. When the moving rod 39 moves, it can drive the flexible column 38 to push against the pump under test 24, thereby pushing out the pump under test 24 for easy unloading.

[0048] Multiple expansion sleeves 48 are fixedly connected to the lower cover 36. The upper cover 32 is provided with snap-fit ​​holes for accommodating the expansion sleeves 48. An expansion post 26 is provided in the snap-fit ​​hole and threadedly connected to the expansion sleeve 48. The expansion sleeve 48 is snapped into the snap-fit ​​hole in the lower cover 36 to limit the upper cover 32. When the expansion post 26 enters and reaches the expansion sleeve 48, it forces the expansion sleeve 48 to expand, thereby making the expansion sleeve 48 press more against the lower cover 36, thus achieving the fixation between the lower cover 36 and the upper cover 32.

[0049] The replacement component includes a movable box housed inside the protective box 18. A driver is fixedly connected inside the movable box, and a drive shaft is driven to the output end of the driver. An eccentric wheel 16 is connected to one end of the drive shaft that passes through a sliding groove. The eccentric wheel 16 cooperates with the horizontal plate 31. A perforated plate 17 is connected to the bottom of the protective box 18. The perforated plate 17 has multiple limiting holes, and a locking pin that passes through the protective box 18 and connects to the movable box is connected to the limiting holes. The movable box can drive the corresponding driver to move, thereby driving the drive shaft and the eccentric wheel 16 to move to the predetermined position. The movable box is then fixed by the locking pin, completing the initial fixation. At this time, by controlling the operation of the driver, the drive shaft and the eccentric wheel 16 are driven to rotate. Due to the shape of the eccentric wheel 16, the horizontal plate 31 is clamped to stabilize its position and facilitate subsequent testing.

[0050] Multiple positioners 06 are connected inside the operation frame 01. An antenna is connected to the top of the operation frame 01. The positioners 06 monitor the final position of each device. When the position of the positioner 06 is exceeded, an electrical signal is triggered to issue a warning. The antenna can be remotely connected to the back-end equipment. An operation panel that is electrically connected to the PLC controller 03 is also connected to one side of the operation frame 01. A protective cover 04 that is rotatably connected to the operation frame 01 is set on the outside of the PLC controller 03. The operation panel facilitates the input of command signals, and the protective cover 04 provides a certain degree of protection for the PLC controller 03.

[0051] The implementation principle of this application embodiment is as follows: Before testing, according to the model of a batch of water pumps, adjust the position of the horizontal plate 31 and the moving box so that they are below the second connector 19. Then, by rotating the eccentric wheel 16, the horizontal plate 31 is engaged, and the two eccentric wheels 16 rotate at different angles, thereby fine-tuning the position of the horizontal plate 31 so that the input end of the pump under test 24 is directly below the second connector 19. This ensures that when the second connector 19 moves downward, its connection with the input end of the pump under test 24 remains stable. After debugging, the horizontal plate 31 is in a stable position, and the testing process can begin. During testing, the pump 24 to be tested is placed between two fixtures 25. At this time, the motor 27 is working, and with the transmission of the gearbox 29 and the transmission rod 47, the base 43 is rotated. Under the limitation of the pull rod 44, the moving rod 39 descends, and at the same time, it drives the two pull rods 44 to move closer to each other, thereby driving the two fixtures 25 to move closer to each other, thus clamping the pump 24 to be tested. After the test is completed, the motor 27 reverses, the moving rod 39 rises, and through the pull rod 44, it drives the two limiting blocks 40 to move away from each other. The fixtures 25 release their clamping, and the flexible column 38 pushes the pump 24 to be tested out, completing one working cycle.

[0052] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
