Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Reference Figure 1 The utility model provides an embodiment of a high-precision detection device for the radial runout of a long cylinder, comprising a support base 1, the bottom end of the support base 1 is fixedly connected to a foot 11, and the bottom end of the foot 11 is threadedly connected to an embedded bolt 12, and the embedded bolt 12 is pre-buried in the concrete foundation of the detection site in advance. The support base 1 can be fixed by threading the foot 11 and the embedded bolt 12 to prevent vibration during the operation of the device, which affects the detection accuracy. The upper surface of the support base 1 is fixedly connected to a guide rail platform 2 by welding. The support base 1 is used to support the guide rail platform 2 to ensure the stability of the device structure. Two parallel guide rails are installed on the guide rail platform 2 to ensure the positioning accuracy and adjustability of the support device and the measuring device. The left side of the upper surface of the guide rail platform 2 is fixedly connected to a lateral limit frame 4 to ensure lateral protection of the workpiece during the entire measurement process to prevent the workpiece from falling.

[0028] The top of the guide rail platform 2 is slidably connected to a drivable bearing support device 5, a measuring table support frame 6 and a limit bearing support device 8 through a slider connecting assembly 7. The slider connecting assembly 7 is used to realize the left and right sliding of the bearing support device and the measuring device, and includes a connecting plate and two sliders. The bottom surface of the connecting plate is fixedly connected to the two sliders. The slider is connected to the two slide rails on the guide rail platform 2, so that the device can adapt to workpieces of different lengths.

[0029] The drivable bearing support device 5 is used in conjunction with the servo motor 3. The power provided by the servo motor 3 causes the fixture supporting the workpiece to rotate, thereby driving the workpiece to rotate, thereby realizing the measurement of the outer surface of the workpiece; the limit bearing support device 8 is used to cooperate with the drivable bearing support device 5 to support the workpiece to realize the rotation movement; the measuring table support frame 6 is used to install the measuring table, which is connected to the slider connection assembly 7 through a magnetic base and can slide left and right along the guide rail platform 2. There are five measuring table support frames 6, which can slide freely within the workpiece measurement range to complete the measurement of the outer surface of the workpiece.

[0030] There are two limit bearing support devices 8. The two limit bearing support devices 8 are slidably connected to the right side of the guide rail platform 2 in a linear array through a slider connecting assembly 7. The limit bearing support device 8 on the right side and the outer side of the drivable bearing support device 5 are both fixedly connected with an axial limit frame 9 by bolts, which is used to realize axial positioning during the workpiece detection process and prevent axial movement of the device. The axial limit frame 9 on the outer side of the drivable bearing support device 5 can ensure the axial positioning of the workpiece from the left side, and the axial limit frame 9 on the outer side of the limit bearing support device 8 on the right side can ensure the axial positioning of the workpiece from the right side.

[0031] The outer sides of the limiting bearing support device 8 and the drivable bearing support device 5 are fixedly connected with a guide rail locking device 10 by bolts. The guide rail locking device 10 is used to realize the positioning function of the limiting bearing support device 8 and the drivable bearing support device 5, fix the support device to the guide rail platform 2, and ensure the axial positioning of the workpiece.

[0032] Reference Figure 2 The drivable bearing support device 5 includes a moving frame, a driving gear 501, a driven gear 502 and a friction wheel 503. The moving frame is slidably connected to the guide rail platform 2 through a slider connecting component 7. The driven gear 502 is rotatably connected to the right surface of the moving frame through a rotating shaft. The friction wheel 503 is fixedly connected to the right surface of the driven gear 502. When the driven gear 502 rotates, the friction wheel 503 can be driven to move synchronously. The driving gear 501 and the driven gear 502 are meshed with each other, and the driven gear 502 and the friction wheel 503 are meshed with each other. The bearing support device 5 can be driven A servo motor 3 is provided on the left side, and the servo motor 3 is fixedly connected to the left side of the mobile frame. The right output end of the servo motor 3 runs through the mobile frame. The right output end of the servo motor 3 is fixedly connected to the driving gear 501. When the servo motor 3 is started, it can drive the driving gear 501 to rotate, and then drive the driven gear 502 to rotate. Since the driven gear 502 is fixedly connected to the friction wheel 503, it can drive the friction wheel 503 to rotate. The friction wheel 503 drives the workpiece to rotate through friction. The servo motor 3 is used to provide power to the drivable bearing support device 5, so that it drives the workpiece to rotate.

[0033] Working principle: Slidingly adjust the spacing between the drivable bearing support device 5 and the limit bearing support device 8 to match the length of the workpiece, place the workpiece on the measuring device through auxiliary mechanical equipment, manually push the drivable bearing support device 5 and the limit bearing support device 8 on both sides of the device, so that the axial limit frame 9 installed on the outside of the two clamps the workpiece to ensure that the workpiece has no axial movement, use the guide rail locking device 10 to fix the drivable bearing support device 5 and the limit bearing support device 8 on the guide rail platform 2, so that the device can detect workpieces of different lengths, which improves the adaptability of the device. It also has the advantages of simple and beautiful appearance, compact structure, small footprint, and no pollution. Slide the measuring table support frame 6 to the measuring position, use the measuring table to measure the outer surface of the workpiece, and after completing the current surface measurement, use the servo motor 3 to drive the workpiece to rotate and measure other surfaces.

[0034] The servo motor 3 starts to drive the driving gear 501 to rotate, and then drives the driven gear 502 and the friction wheel 503 to rotate. The friction wheel 503 drives the workpiece to rotate through friction to achieve the purpose of measuring the workpiece surface change. Then the measuring table support frame 6 is repeatedly moved to adjust the measuring table to complete the workpiece measurement.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
