[0001] This invention relates to the field of vortex disk detection technology, and in particular to a high-precision and rapid detection device for the outer diameter of the vortex disk support lug. Background Technology

[0002] The scroll compressor has lugs on its scroll drive plate. After the scroll drive plate is machined, the distance between the middle areas of the lugs needs to be checked to ensure that it is within the acceptable range. However, since the end face of the lug is inclined, it is not convenient to align the middle area by measuring with rulers and gauges. Using a coordinate measuring machine for inspection would lead to a complicated inspection process and low inspection efficiency. Therefore, it is necessary to make it easier to perform rapid inspection. Summary of the Invention

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0025] Reference Figures 1-6 A high-precision and rapid detection device for the outer diameter of a vortex moving disk support lug includes a moving disk body 1, a support lug 2 fixedly connected to the outer surface of the moving disk body 1, the support lug 2 being integrally formed with the moving disk body 1, a detection mechanism installed on the surface of the moving disk body 1, the detection mechanism detecting the support lug 2 on the outer side of the moving disk body 1; a drive mechanism is installed at the lower end of the detection mechanism, the drive mechanism driving the moving disk body 1 to rotate.

[0026] To detect the outer diameter of the lug 2, a detection mechanism is set up, including a displacement sensor 3. A screw 31 is slidably inserted into the shaft of the moving plate body 1. A pressure plate 32 is threaded onto the upper surface of the screw 31. The pressure plate 32 is located above the moving plate body 1. The moving plate body 1 is movably installed using the pressure plate 32 in conjunction with the screw 31, so that the moving plate body 1 can rotate together with the screw 31. The lower end of the screw 31 is rotatably connected to a detection platform 33 via a bearing. The detection platform 33 is located below the moving plate body 1. A mounting plate 34 is fixedly connected to the upper edge of the detection platform 33. One end of the displacement sensor 3 is fixedly connected to the surface of the mounting plate 34. The displacement sensor 3 is used to detect the displacement of the detection plate 36. The outer diameter of the lug 2 is calculated by performing a test, and the displacement sensor 3 is connected to external calculation software to directly calculate the outer diameter of the lug 2. A telescopic rod 35 is fixedly connected to the surface of the mounting plate 34, and a detection plate 36 is fixedly connected to the movable end of the telescopic rod 35. The two detection plates 36 are located on both sides of the moving plate body 1. The telescopic rod 35 is filled with a spring 37. When the detection plate 36 is close to the moving plate body 1, the lug 2 on the surface of the moving plate body 1 presses the detection plate 36 when the moving plate body 1 rotates. The outer diameter of the lug 2 is the distance between the center of the detection plate 36 and the screw 31 after the telescopic rod 35 is extended, plus the displacement of the detection plate 36 after the lug 2 presses the detection plate 36.

[0027] To improve detection accuracy, a groove is provided on the upper surface of the detection stage 33. An air box 38 is fixedly connected to the inner wall of the groove. Air holes are provided on the upper surface of the air box 38. Multiple air holes are distributed in a grid pattern on the upper surface of the air box 38. The detection plate 36 is located above the air box 38. Air is blown downwards from the air box 38 through the air holes, thereby reducing the friction when the detection plate 36 slides.

[0028] By installing a detection mechanism on the surface of the moving plate body 1, the detection plate 36 in the detection mechanism is brought close to the moving plate body 1. The moving plate body 1 is rotated, and the support lug 2 on the surface of the moving plate body 1 is pressed against the detection plate 36. The displacement sensor 3 measures the displacement of the detection plate 36, and then calculates the outer diameter of the support lug 2. The measurement is automated, with no human error. Only the moving plate body 1 needs to be replaced manually. The operation is simple and the detection efficiency is high.

[0029] To drive the moving disk body 1, a drive mechanism is provided, including a dual-axis drive motor 4. A base 41 is fixed on the lower surface of the detection table 33. The dual-axis drive motor 4 is located inside the base 41. The output shaft of the dual-axis drive motor 4 is connected to the lower end of the screw 31. The dual-axis drive motor 4 provides power for the rotation of the moving disk body 1, thereby facilitating the control of the rotation of the moving disk body 1. The output shaft of the dual-axis drive motor 4 is transmitted between the screw 31 and the screw through a reduction gearbox, thereby preventing the screw 31 from driving the moving disk body 1 to rotate too fast.

[0030] A fixing plate 42 is fixedly connected to the inner wall of the base 41. The two fixing plates 42 are vertically distributed. The lower surface of the upper fixing plate 42 is rotatably connected to a turntable 43 via a rotating shaft. The surface of the turntable 43 is connected to the output shaft of the dual-axis drive motor 4 via a rotating shaft. The dual-axis drive motor 4 is used as a power source, which facilitates the dual-axis drive motor 4 to simultaneously drive the turntable 43 and the screw 31. Guide posts 44 are fixedly connected to the opposite surfaces of the two fixing plates 42. An extrusion seat 45 is slidably sleeved on the surface of the guide posts 44. An adjustment groove is opened on the upper surface of the extrusion seat 45. An adjustment block 46 is slidably connected to the inner wall of the adjustment groove. The upper surface of the adjustment block 46 is fixedly connected to the lower surface of the turntable 43. A ball head seat 47 has a ball head rod 48 slidably connected to its inner wall. The ball head seat 47 is eccentrically mounted on the lower surface of the turntable 43, which facilitates the sliding of the ball head rod 48 when the turntable 43 rotates. A lead screw 49 is rotatably connected to the inner wall of the extrusion seat 45 via a bearing. The surface of the lead screw 49 is threadedly engaged with the inner wall of the adjusting block 46. The lead screw 49 and the adjusting block 46 drive the lower end of the ball head rod 48 to offset, thereby facilitating the adjustment of the range of motion of the ball head rod 48. A rubber air cylinder 5 is fixedly connected to the lower surface of the extrusion seat 45. The air outlet of the rubber air cylinder 5 is connected to the inside of the air box 38 via an air pipe. The rubber air cylinder 5 provides an air source for the air jet of the air box 38, thereby facilitating the long-term use of the air box 38.

[0031] By setting up a drive mechanism to provide power to the detection mechanism, the dual-axis drive motor 4 in the drive mechanism simultaneously drives the turntable 43 and the screw 31, so that the extrusion seat 45 repeatedly extrudes the rubber airbag. By generating an air cushion under the detection plate 36, the friction of the detection plate 36 during its movement is reduced, thereby improving the accuracy of the detection mechanism.

[0032] Working principle:

[0033] In use, the moving disc body 1 is fitted onto the surface of the screw 31, and then the pressure plate 32 is screwed into the surface of the moving disc body 1. The pressure plate 32 fixes the moving disc body 1 to the surface of the screw 31. The dual-axis drive motor 4 is started, and the dual-axis drive motor 4 drives the moving disc body 1 to rotate through the screw 31. When the moving disc body 1 rotates, the lug 2 presses against the surface of the detection plate 36, and the detection plate 36 comes into contact with the surface of the mounting plate 34. The telescopic rod 35 is compressed, the spring 37 is compressed, and the displacement sensor 3 measures the displacement of the detection plate 36.

[0034] At the same time, the dual-axis drive motor 4 drives the turntable 43 to rotate. The turntable 43 drives the adjusting block 46 through the ball head seat 47 and the ball head rod 48. The adjusting block 46 drives the extrusion seat 45 to reciprocate and rise and fall through the lead screw 49. The extrusion seat 45 repeatedly extrudes the rubber airbag. The rubber airbag sprays air into the air box 38 through the air pipe. The gas in the air box 38 is sprayed upward through the air hole and forms an air cushion below the detection plate 36.

[0035] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
