The clamping plate effectively secures the laser displacement sensor, preventing it from loosening due to vibration or movement during testing and thus ensuring more accurate measurement results.

Description

Technical Field

[0001] This utility model belongs to the field of flatness detection technology, and in particular relates to a shaft flatness detection device. Background Technology

[0002] A shaft straightness testing device is an instrument used to detect whether a rotating shaft remains straight. It is mainly used to check whether the shaft is bent, deviated, or irregular in shape during rotation or use. This type of testing is crucial for ensuring the normal operation of mechanical equipment and extending its service life.

[0003] During the shaft straightness detection process, external vibrations in the environment may be transmitted to the detection equipment, causing the equipment to shake. This shaking can loosen the sensor, making it impossible to accurately acquire data and resulting in deviations in the measurement results. Therefore, we propose a shaft straightness detection device. Utility Model Content

[0004] The purpose of this invention is to provide a shaft straightness detection device. By turning a knob, a threaded rod is rotated, which in turn moves a threaded cylinder. The threaded cylinder then uses a transmission mechanism to clamp a laser displacement sensor with a clamping plate, thus solving the problem of clamping and fixing the laser displacement sensor.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a shaft straightness testing device, including a support platform, a fixing mechanism on the top of the support platform, and an adjustment mechanism on the bottom of the support platform;

[0007] The fixing mechanism includes a slide table, a fixing body fixedly connected to the top of the slide table, a connecting circular frame fixedly connected to the outer surface of the fixing body, a placement plate fixedly connected to the inner wall of the connecting circular frame, a clamping plate slidably connected to the inner wall of the placement plate, a moving rod rotatably connected to the inner wall of the clamping plate, a connecting block rotatably connected to the end of the moving rod away from the clamping plate, a threaded cylinder fixedly connected to the side of the connecting blocks that are close to each other, a threaded rod threadedly connected to the inner wall of the threaded cylinder, a knob fixedly connected to the end of the threaded rod that is away from the placement plate, a limiting rod fixedly connected to the outer surface of the placement plate, a fixing frame fixedly connected to the end of the limiting rod that is close to the connecting block, and a laser displacement sensor slidably connected to the side of the clamping plates that are close to each other. By clamping the laser displacement sensor with clamping plates, the laser displacement sensor can be clamped and fixed, avoiding errors caused by the laser displacement sensor loosening due to vibration or movement during the detection process, thus making the measurement results more accurate.

[0008] Furthermore, the outer surface of the slide table is slidably connected to the inner wall of the support platform, four clamping plates are provided in total, the outer surface of the threaded rod is rotatably connected to the inner wall of the placement plate, and the outer surface of the threaded rod is rotatably connected to the inner wall of the connecting circular frame.

[0009] Furthermore, the outer surface of the knob is rotatably connected to the outer surface of the connecting circular frame, and four limiting rods are provided in total. The outer surface of the limiting rods is slidably connected to the inner wall of the clamping plate, and the outer surface of the fixing frame is fixedly connected to the outer surface of the placement tray.

[0010] Furthermore, the adjustment mechanism includes a bolt threaded to the inner wall of the slide table, the outer surface of the bolt being threaded to the inner wall of the support table, and a sliding rod fixedly connected to the bottom of the support table, with a total of four sliding rods provided.

[0011] Furthermore, a connecting frame is slidably connected to the outer surface of the sliding rod, a base is fixedly connected to the bottom of the connecting frame, and a limit block is fixedly connected to the top of the base. There are two limit blocks in total.

[0012] Furthermore, a threaded rod is rotatably connected to the inner wall of the limiting block, and a knob is fixedly connected to the outer surface of the threaded rod, with the outer surface of the knob rotatably connected to the outer surface of the limiting block.

[0013] Furthermore, a limiting groove is fixedly connected to the outer surface of the connecting frame. There are two limiting grooves in total. A slider is slidably connected to the inner wall of the limiting groove. A threaded cylinder is fixedly connected to the side of the slider that is close to each other.

[0014] Furthermore, the inner wall of the threaded cylinder two is threadedly connected to the outer surface of the threaded rod two, and a moving rod two is rotatably connected to the inner wall of the threaded cylinder two. A connecting block two is rotatably connected to the end of the moving rod two away from the threaded cylinder two. The top of the connecting block two is fixedly connected to the bottom of the support platform. Through the support platform with adjustable height and the slide table with adjustable horizontal position, the laser displacement sensor can be kept in the optimal measurement position, which helps to maintain stable measurement conditions, ensures more accurate measurement results, and avoids errors caused by position deviation.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model incorporates a clamping plate. The laser displacement sensor is placed on the bottom clamping plate, ensuring it is firmly attached to the placement tray. Rotating the knob causes the threaded rod to rotate, which in turn moves the threaded cylinder towards the knob. The threaded cylinder then pulls the moving rod via the connecting block pair. This movement causes the clamping plate to slide within the placement tray. The clamping plate effectively secures the laser displacement sensor, preventing it from becoming loose due to vibration or movement during testing and thus ensuring more accurate measurement results.

[0017] 2. This utility model incorporates a threaded rod II. Rotating the knob II causes the threaded rod II to rotate, which in turn causes the threaded cylinder II to move to the left along the threaded rod II. The threaded cylinder II then pushes the moving rod II, which in turn pushes the support platform via the connecting block II, causing the support platform to move upward. Simultaneously, the support platform also causes the sliding rod to slide within the connecting frame. By using a height-adjustable support platform and a horizontally adjustable sliding platform, the laser displacement sensor can be positioned at the optimal measurement location, helping to maintain stable measurement conditions and ensuring more accurate measurement results, thus avoiding errors caused by positional deviations.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0033] One specific application of this embodiment is:

[0034] When the operator needs to use the equipment, the laser displacement sensor 211 can be placed on the bottom clamping plate 205, ensuring it is firmly against the placement plate 204. Then, the knob 210 is rotated, causing the threaded rod 209 to rotate. The threaded rod 209 then moves the threaded cylinder 208 towards the knob 210. The threaded cylinder 208 pulls the moving rod 206 via the connecting block 207. The movement of the moving rod 206 causes the clamping plate 205 to slide within the placement plate 204, and simultaneously slides on the limiting rod 212, thus clamping the laser displacement sensor 211. This secure clamping prevents the laser displacement sensor 211 from loosening due to vibration or movement during the testing process, leading to more accurate measurement results. Then, the knob 307 is rotated. 307 drives the threaded rod 306 to rotate, and then the threaded rod 306 causes the threaded cylinder 310 to move to the left along the threaded rod 306. At this time, the threaded cylinder 310 pushes the moving rod 311, and then the moving rod 311 pushes the support platform 101 through the connecting block 312, causing the support platform 101 to move upward. At the same time, the support platform 101 also drives the sliding rod 302 to slide within the connecting frame 303, causing the support platform 101 to move the laser displacement sensor 211, so that the laser displacement sensor 211 is kept horizontal with the rotating shaft to be detected. Then, the bolt 301 is loosened, and the slide 201 is slid within the support platform 101 to adjust the laser displacement sensor 211 to a suitable position. Then, the bolt 301 is tightened to fix the position of the laser displacement sensor 211, so that the laser displacement sensor 211 can stay in the optimal measurement position, which helps to maintain stable measurement conditions, ensures more accurate measurement results, and avoids errors caused by position deviation.
