Description

Technical Field

[0001] This application relates to the field of coaxiality calibration technology, specifically to a coaxiality calibration device for detecting the roundness of shafts. Background Technology

[0002] Shaft roundness inspection measures the deviation of the cross-sectional profile of a shaft part from an ideal circle to assess its roundness. The inspection results directly affect the assembly accuracy and operational performance of the part, and are commonly used in the quality control of rotating components such as bearings and gears. Coaxiality calibration devices are specialized measuring instruments used to detect and calibrate the coaxiality of two axes of mechanical parts or equipment. They employ sensors (such as laser displacement sensors or CCD cameras) to collect position data at multiple points along the axial direction, typically requiring rotation of the measuring device to obtain full-circumference data.

[0003] In existing coaxiality calibration devices, the gear is placed on the support cylinder of the device, and the drive device at the bottom of the device drives the gear to rotate through the support cylinder. This allows the laser displacement sensor of the device to accurately detect the coaxiality of the gear. However, the support cylinder of the device is not easy to adjust in height, making it inconvenient for the device to detect different positions of the gear.

[0004] Therefore, there is an urgent need for a coaxiality calibration device for shaft roundness testing to solve the problem that coaxiality calibration devices are inconvenient for testing different positions of gears. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a coaxiality calibration device for shaft roundness detection, which has the advantage of comprehensively detecting gears and solves the problem that coaxiality calibration devices are inconvenient for detecting different positions of gears.

[0006] To achieve the above objectives, this application provides the following technical solution: a coaxiality calibration device for shaft roundness detection, comprising a testing platform, a support box, a guide rod, and a coaxiality calibration device body. The support box is fixedly connected to the top of the testing platform by bolts, and both ends of the guide rod are fixedly connected to the inner side of the support box by bolts. A slider at the bottom of the coaxiality calibration device body is slidably connected to the outer surface of the guide rod. An adjustment mechanism is provided at the bottom of the testing platform, and a clamping mechanism is provided at the top of the testing platform. The adjustment mechanism includes a fixed frame, a drive motor, a threaded rod, a threaded sleeve, a first support frame, a support base, a drive device, and a support cylinder. The fixed frame is fixedly connected to the bottom of the testing platform at both ends by bolts. The drive motor is installed at the middle position of the bottom of the fixed frame. One end of the threaded rod is fixedly connected to the output end of the drive motor, and the other end of the threaded rod is threadedly connected to one end of the threaded sleeve. The threaded sleeve is fixedly connected to the bottom of the first support frame by bolts. The two ends of the first support frame are welded to the outside of the support base. The support base is slidably connected to the slot on the inside of the testing platform. The drive device is installed at the bottom of the support base. The bottom of the support cylinder is fixedly connected to the output end of the drive device, and the support cylinder is rotatably connected to the inside of the support base.

[0007] By adjusting the position of the threaded sleeve, the threaded sleeve drives the support base to move up and down through the support frame. When the support base moves, it drives the gear to move up and down through the support cylinder, so that the coaxiality calibration device can detect different positions of the gear in the vertical direction, thereby comprehensively inspecting the gear.

[0008] Preferably, the support cylinder is connected to the support base via a bearing, and a circular slot is provided at the top of the support cylinder.

[0009] Preferably, the fixing frame and the support frame are U-shaped frames.

[0010] Preferably, the clamping mechanism includes a second support frame, a first cylinder, a support rod, a first connecting rod, and an insert rod. The second support frame is fixedly connected to the top of the testing table by bolts. The first cylinder is installed on the top of the second support frame. One end of the support rod is fixedly connected to the output end of the first cylinder. The other end of the support rod is rotatably connected to the first connecting rod. The insert rod is located at the bottom of the first connecting rod.

[0011] Preferably, the support rod is connected to the connecting rod 1 via a bearing, and the connecting rod 1 is integrally formed with the insertion rod.

[0012] Preferably, a fixed base is fixedly connected to the top of the testing platform by bolts, a cylinder two is installed on the top of the fixed base, a connecting rod two is fixedly connected to the output end of the cylinder two, and the other end of the connecting rod two is fixedly connected to one side of the coaxiality calibration device body by bolts.

[0013] In summary, this application includes at least one of the following beneficial effects: 1. This coaxiality calibration device for shaft roundness testing allows the gear to be placed on a support cylinder. By adjusting the position of the threaded sleeve, the threaded sleeve drives the support base to move up and down via the support frame one. When the support base moves, it drives the gear to move up and down via the support cylinder, allowing the coaxiality calibration device to detect different positions of the gear in the vertical direction, thus comprehensively testing the gear. At the same time, cylinder two drives the coaxiality calibration device to move via connecting rod two, allowing the coaxiality calibration device to detect gears of different sizes, making the coaxiality calibration device more convenient to use.

[0014] 2. The coaxiality calibration device used for the roundness detection of this shaft is activated when the gear is placed on top of the support cylinder for detection. The cylinder drives the connecting rod and the insert rod to move up and down through the support rod. When the insert rod moves down, it is inserted into the circular groove of the gear. The connecting rod presses the gear together, making it less likely for the gear to deviate or move during detection, thus making the gear detection more accurate. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

The two ends of the guide rod 3 are fixedly connected to the inner side of the support box 2 by bolts. The slider at the bottom of the coaxiality calibration device body 4 is slidably connected to the outer surface of the guide rod 3. The support block at the bottom of the coaxiality calibration device body 4 can slide on the outer surface of the guide rod 3, so that the position of the coaxiality calibration device body 4 can be easily adjusted. An adjustment mechanism is provided at the bottom of the testing platform 1, and a clamping mechanism is provided at the top of the testing platform 1.

[0019] Specifically, the adjustment mechanism includes a fixed frame 111, a drive motor 112, a threaded rod 113, a threaded sleeve 114, a support frame 115, a support base 116, a drive device 117, and a support cylinder 118. The fixed frame 111 is bolted to the bottom of the testing platform 1 at both ends. The drive motor 112 is installed at the middle of the bottom of the fixed frame 111. One end of the threaded rod 113 is fixedly connected to the output end of the drive motor 112, and the other end of the threaded rod 113 is threadedly connected to one end of the threaded sleeve 114. The threaded sleeve 114 is bolted to the fixed frame 111. At the bottom of support frame 115, both ends of support frame 115 are welded to the outside of support base 116. Fixing frame 111 and support frame 115 are U-shaped frames. Support base 116 is slidably connected to the slot inside the test table 1. Drive device 117 is installed at the bottom of support base 116. The bottom of support cylinder 118 is fixedly connected to the output end of drive device 117. Support cylinder 118 is rotatably connected to the inside of support base 116. Support cylinder 118 is connected to support base 116 through bearing. A circular slot is opened at the top of support cylinder 118.

[0020] Through the above technical solution, the gear can be placed on the support cylinder 118. The locking block inside the support cylinder 118 can lock the gear in the slot inside. Start the drive motor 112, which drives the threaded rod 113 to rotate. The threaded rod 113 drives the threaded sleeve 114 to move up and down. By adjusting the position of the threaded sleeve 114, the threaded sleeve 114 drives the support seat 116 to move up and down through the support frame 115. When the support seat 116 moves, it drives the gear to move up and down through the support cylinder 118. Thus, the coaxiality calibration device body 4 can detect different positions of the gear in the vertical direction, thereby comprehensively detecting the gear.

[0021] Specifically, the clamping mechanism includes a second support frame 211, a first cylinder 212, a support rod 213, a first connecting rod 214, and an insertion rod 215. The second support frame 211 is fixedly connected to the top of the testing table 1 by bolts. The first cylinder 212 is installed on the top of the second support frame 211. One end of the support rod 213 is fixedly connected to the output end of the first cylinder 212, and the other end of the support rod 213 is rotatably connected to the first connecting rod 214. The support rod 213 is connected to the first connecting rod 214 through a bearing. The first connecting rod 214 and the insertion rod 215 are integrally formed, and the insertion rod 215 is located at the bottom of the first connecting rod 214.

[0022] With the above technical solution, when the gear is placed on top of the support cylinder 118 for testing, cylinder 212 is activated. Cylinder 212 drives connecting rod 214 and insert rod 215 to move up and down through support rod 213. When insert rod 215 moves down, it is inserted into the circular groove of the gear. Connecting rod 214 presses the gear tightly, making it less likely for the gear to deviate or move during testing, thus making the gear testing more accurate.

[0023] Specifically, a fixed base 311 is fixedly connected to the top of the testing table 1 by bolts. A cylinder 312 is installed on the top of the fixed base 311. A connecting rod 313 is fixedly connected to the output end of the cylinder 312. The other end of the connecting rod 313 is fixedly connected to one side of the coaxiality calibration device body 4 by bolts.

[0024] With the above technical solution, cylinder 312 is activated, and cylinder 312 drives the coaxiality calibration device body 4 to move through connecting rod 313. The slider at the bottom of the coaxiality calibration device body 4 slides on the outer surface of the guide rod 3. By adjusting the position of the coaxiality calibration device body 4, the coaxiality calibration device body 4 can detect gears of different sizes, making the coaxiality calibration device more convenient to use.

[0025] In use, by adjusting the position of the threaded sleeve 114, the threaded sleeve 114 drives the support base 116 to move up and down through the support frame 115. When the support base 116 moves, it drives the gear to move up and down through the support cylinder 118, so that the coaxiality calibration device body 4 can detect different positions of the gear in the vertical direction, thereby comprehensively detecting the gear.
