Different pump bodies are matched according to different tolerances to ensure the sealing effect of the assembled oil pump and extend its mechanical life. Since all impellers produced need to be fully inspected, the inspection volume is large. Existing impeller thickness inspection generally relies on specialized tooling and manual operation to inspect each impeller individually, resulting in low inspection efficiency, high inspection costs, and frequent large inspection deviations. Therefore, there is an urgent need for an oil pump impeller inspection device that can automatically measure and sort impeller dimensions and thickness in batches to improve inspection efficiency and accuracy, and effectively reduce inspection costs. Summary of the Invention

[0024] See Figures 1-10The present invention relates to an oil pump impeller testing device, comprising a workbench 1, a turntable turret 2, a feeding and transferring mechanism 3, a testing mechanism 4, a discharging and transferring mechanism 5, and a discharging fixture 6, which are sequentially installed on the workbench 1. The turntable hopper 2 includes a turntable 21 and several groups of hoppers 22 arranged on the circumference of the turntable 21. Each group of hoppers 22 has multiple oil pump impellers 7 stacked vertically. The hopper 22 is formed by several vertical tower rods. A turntable drive mechanism is arranged on the outside of the turntable 21, several indexing rods 23 are evenly arranged around the bottom, and an impeller lifting mechanism is arranged below. The turntable drive mechanism pushes the indexing rods 23 to move and realize the rotation of the turntable 21. The impeller lifting mechanism lifts the oil pump impellers 7 one by one out of the hopper 22. The turntable drive mechanism includes an indexing drive cylinder 24, a slide rail 25, a slider 26 slidably mounted on the slide rail 25 and driven by the indexing drive cylinder 24 to reciprocate, an indexing positioning cylinder 27 fixed on the slider 26, and a locking block 28 located at the movable end of the indexing positioning cylinder 27; the locking block 28 and the indexing rod 23 are nested together; when all the oil pump impellers 7 in a set of material towers 22 have been tested, the indexing positioning cylinder 27 pushes the locking block 28 to lock the indexing rod 23, and then the indexing drive cylinder 24 pushes the slider 26, the indexing positioning cylinder 27 and the locking block 28 to move as a whole, thereby causing the indexing rod 23 to deflect, thereby causing the turntable 21 to deflect one indexing position, so that the next set of material towers 22 is in the position to be discharged. Since the locking block 28 performs a translational movement and the indexing rod 23 performs an arc-shaped circumferential deflection movement, the two movements are coordinated by the indexing rod 23 moving within the long empty slot of the locking block 28. In addition, an indexing limit cylinder 20 is provided below the turntable 21. A sleeve is provided at the top movable end of the cylinder. The sleeve is used to lock the position of the turntable 21 by sliding it onto the indexing rod 23, ensuring the accuracy of the rotation position of the material tower 22. When the turntable 21 needs to rotate, the indexing limit cylinder 20 drives the sleeve to descend and disengage from the indexing rod 23. The impeller lifting mechanism includes an impeller cylinder 72 driven by an electric cylinder 71 to perform lifting and lowering actions, and an impeller lifting block 73 located at the movable end of the impeller cylinder 72. The electric cylinder 71 lifts the impeller lifting block 73 to the top of the oil pump impeller 7, the impeller cylinder 72 pushes out the impeller lifting block 73 so that it is inserted below the oil pump impeller 7, and then the electric cylinder 71 lifts the impeller lifting block 73 and the oil pump impeller 7 to the discharge tower 22 until the material grabbing position of the feeding and transferring mechanism 3, so that the feeding and transferring mechanism 3 can grab and feed the material. After the feeding and transferring mechanism 3 takes the material, the electric cylinder 71 drives the impeller lifting block 73 to descend to the next oil pump impeller 7, and repeats the above actions to achieve continuous feeding of each impeller. The feeding and transferring mechanism 3 transfers the oil pump impellers 7 in the material tower 22 one by one to the detection mechanism 4. It includes a feeding slide cylinder 31, a feeding rotary cylinder 32, a feeding arm 33, and feeding pneumatic grippers 34 installed at both ends of the feeding arm 33. The feeding slide cylinder 31 drives the feeding rotary cylinder 32 to perform lifting and lowering actions. The feeding rotary cylinder 32 drives the feeding arm 33 to perform a 180° rotation action. The feeding pneumatic grippers 34 grab the oil pump impellers 7 and achieve repeated feeding function by relying on the lifting and rotation actions of the feeding slide cylinder 31 and the feeding rotary cylinder 32. The detection mechanism 4 includes a rotating seat 41, a test seat 42 disposed on the circumference of the rotating seat 41, and a thickness detection device 43 disposed on the side of the rotating seat 41; the feeding pneumatic gripper 34 places the oil pump impeller 7 on the test seat 42, and the rotating seat 41 rotates to rotate the test seat 42 containing the oil pump impeller 7 to the detection device 43 for thickness detection. The thickness detection device 43 includes a C-shaped support base 431, thickness sensors 432 mounted symmetrically on the upper and lower parts of the C-shape of the support base 431, and a fixed cylinder 433 mounted on the upper part of the C-shape of the support base 431. In this embodiment, the thickness sensors 432 are cylinder-type high-precision sensors, model GT2-PA12K, totaling six, with three on each side arranged opposite each other. When testing the impeller thickness, the movable end of the fixed cylinder 433 first extends downward to press the oil pump impeller 7 against the test base 42 to fix the impeller position. Then, the upper and lower sensors simultaneously extend towards the impeller and press against the upper and lower surfaces of the impeller to obtain three sets of thickness data. The average value is taken as the final measured thickness. To further ensure the accuracy of impeller thickness detection, a dust collection device and an air blowing pipe 44 are installed on the outside of the rotating seat 41. The dust collection device includes a dust collection pipe 45, a dust collection bag 46, and an air intake 47. The air intake 47 is connected to the side of the dust collection pipe 45, and the dust collection bag 46 is installed at the tail of the dust collection pipe 45. The air blowing pipe 44 is a flexible hose, which is aimed at the test seat 42 and blows air to blow away the dust on the test seat 42 to prevent it from affecting the thickness measurement accuracy. Similarly, using the negative pressure of the air intake 47, the dust collection pipe 45 sucks the dust near the test seat 42 into the dust collection bag 46 to prevent dust from accumulating on the test seat 42 and affecting the thickness measurement accuracy. The structure and working principle of the unloading and transferring mechanism 5 are similar to those of the loading and transferring mechanism 3. It includes an unloading slide cylinder 51, an unloading rotary cylinder 52, an unloading arm 53, and unloading pneumatic grippers 54 installed at both ends of the unloading arm 53. The unloading slide cylinder 51 drives the unloading rotary cylinder 52 to perform lifting and lowering actions. The unloading rotary cylinder 52 drives the unloading arm 53 to rotate 180°. The unloading pneumatic grippers 54 clamp the oil pump impeller 7 that has completed the test on the test seat 42, rotate it, and transfer it to the unloading fixture 6. The unloading fixture 6 includes an X-axis slide rail 61 mounted on the worktable 1, an unloading base 62 slidably mounted on the X-axis slide rail 61, a Y-axis slide rail 63 mounted on the unloading base 62, an unloading fixture table 64 slidably mounted on the Y-axis slide rail 63, and multiple unloading stations 65 mounted on the unloading fixture table 64. The unloading base 62 is driven to slide by an X-axis electric cylinder 66, and the unloading fixture table 64 is driven to slide by a Y-axis electric cylinder 67. According to the thickness test data, the oil pump impeller 7 with a thickness tolerance within 10 micrometers is placed in the same unloading station 65. By using the unloading base 62 to move in two dimensions in the X and Y directions, the corresponding unloading station 65 is controlled to move to below the unloading pneumatic gripper 54. The unloading pneumatic gripper 54 releases the oil pump impeller 7 to complete the unloading of the impeller. The working process of the oil pump impeller detection device of the present invention is as follows: First, the oil pump impellers 7 are stacked manually in each group of material towers 22 of the turntable 21; the impellers in the material towers 22 are lifted one by one to the gripping position of the feeding and transferring mechanism 3 by the rotation of the material towers 22 and the impeller lifting mechanism; the feeding and transferring mechanism 3 transfers the impellers to the test seat 42; the rotating seat 41 rotates one station, the thickness detection device 43 detects the thickness of the impeller, the rotating seat 41 continues to rotate one station, and the unloading and transferring mechanism 5 grabs and transfers it to the unloading fixture 6; according to the thickness data, the unloading base 62 moves the corresponding unloading station 65 to the underside of the unloading pneumatic gripper 54, the unloading pneumatic gripper 54 releases the impeller, and the oil pump impellers 7 are sorted and stored according to thickness, thus realizing the sorting of impellers.

[0025] Additionally, it should be noted that the above-described specific implementation is merely an optimized solution of this patent, and any modifications or improvements made by those skilled in the art based on the above concept are within the scope of protection of this patent.
