In addition, the existing roller detection equipment has a limited scope of application and cannot be applied to rollers of different sizes, widths and diameters. Summary of the invention

[0015] Working principle: First, when testing the first measured roller, the first drive motor starts and drives the screw rod to rotate, so that the two sliders slide on the moving bar to move closer to the center, and the gap between them is adjusted to the size of the first measured roller. Then, the top fixing covers of the two roller fixing mechanisms are opened, and the two ends of the first measured roller are placed on the roller fixing mechanisms respectively, and then the first measured roller is limited by the fixing covers. Then the second drive motor in the clamping mechanism is also started, so that the roller noise and vibration detection mechanism moves downward until the two driving wheels contact the first measured roller, so that the first measured roller is also stuck between the two roller fixing mechanisms for radial load detection and radial circular runout detection. When the second measured roller needs to be tested, the same first drive motor is started and drives the screw rod to rotate, so that the two sliders slide on the moving bar and move to both sides, and the second measured roller is moved closer to the center. The roller is placed between the two roller support mechanisms, and as the second drive motor in the clamping mechanism is started, the roller noise and vibration detection mechanism is moved downward until the two driving wheels contact the second measured roller, and finally the servo motor is started to drive the two driving wheels to rotate and start to drive the second measured roller to rotate, thereby performing roller noise and vibration detection work. When the third measured roller is detected, the first drive motor is started to drive the lead screw to rotate, so that the two sliders slide on the moving bar toward the center, so that the two ends of the third measured roller can be placed on the corresponding third pressurizing device, and the right end of the third measured roller is inserted into the displacement sensor, and the left end of the third measured roller is inserted into the clamping structure of the corresponding motor output end. As the motor is started, the third measured roller is driven to rotate, so that the third measured roller is subjected to a rotational resistance test and an axial displacement test.

[0018] 2. The present invention starts the first driving motor to drive the lead screw to rotate, so that the two sliders can slide on the moving bar to move toward the center and to both sides, and the roller noise and vibration detection mechanism moves downward until the two driving wheels contact the roller to be tested, so that the roller detection equipment has a wider range of application and can be applied to rollers of different sizes and widths and diameters.

[0028] The radial runout detection mechanism 3 comprises a laser sensor 301 , and roller fixing mechanisms 303 are fixedly connected to adjacent sides of the top of the slider, and a first detected roller 302 is arranged between the two roller fixing mechanisms 303 .

[0029] The moving bar is located at the top center of the frame main body platform 2, and the moving bar is arranged horizontally. An empty slot is opened at the top of the frame main body platform 2 in the space between the moving bars, and the tested roller can be placed in the empty slot space.

[0031] The sliding guide rails 901 are two T-shaped rails arranged in parallel, and the roller support mechanism 505 includes a support frame and two rollers, which are connected to the slider through the support frame, and the rollers are rotatably connected to the support frame.

[0032] The front side of the sliding guide rail 901 is slidingly connected with a roller noise and vibration detection mechanism 8, and a roller clamping rotation drive mechanism 4 is arranged inside the roller noise and vibration detection mechanism 8. The front bottom of the roller clamping rotation drive mechanism 4 is fixedly connected with a second pressurizing device 506, and the bottom of the second pressurizing device 506 is rotatably connected with a driving wheel 401.

[0033] The second pressurizing device 506 is a bracket with an opening downward, and two driving wheels 401 are rotated at the bottom of the bracket. When working, the tested roller is located between the two driving wheels 401, and a threaded rod is threadedly connected to the rear side of the roller noise and vibration detection mechanism 8.

When the servo motor 504 is started, the output end rotates, thereby driving the transmission belt of the first pressurizing device 304. The transmission belt of the first pressurizing device 304 transmits power to the two driving wheels 401. Because the two driving wheels 401 are driven by one first pressurizing device 304, the rotation directions and rotation speeds of the two driving wheels 401 are consistent.

[0037] As the two sliders move toward the center, the space between the two sliders is adjusted to the width of the roller to be tested, so that both sides of the roller to be tested can be placed on the top of the third pressure device 604, and a motor is also set on the left support seat 603. After the roller is placed, the left end of the roller is inserted into the clamping part of the motor. As the motor is started, the roller can be rotated for detection.

[0039] The first drive motor 605 is composed of two parts, including a motor and a reducer. The motor is started to provide power for the reducer. A transmission belt is set between the output end of the reducer and the left end of the screw rod 606, so that the reducer can drive the screw rod 606 to rotate after it works. The screw rod 606 and the slider are threadedly connected. As the screw rod 606 rotates, the two sliders move toward the center on the moving bar.

[0040] A second driving motor 701 is fixedly connected to the top of the clamping mechanism 9 .

[0041] The second drive motor 701 is also composed of two parts, including a motor and a reducer. The motor is started to provide power to the reducer, so that the reducer drives the corresponding structure to work. The output end of the reducer in the second drive motor 701 is fixedly connected to a threaded rod on the rear side of the roller noise and vibration detection mechanism 8. As the reducer is driven by the motor, the output end of the reducer also drives the threaded rod to rotate and drives the roller noise and vibration detection mechanism 8 to move horizontally up and down.

[0042] A third measured roller 602 is arranged between the two third pressure devices 604 , and a displacement sensor 607 is fixedly connected to the top of the right support seat 603 .

[0043] The third detected roller 602 is detected by the displacement sensor 607 when rotating.

[0044] A rotation speed torque sensor 503 is fixedly connected to adjacent sides of the tops of the two roller support mechanisms 505 , and a second measured roller 502 is arranged between the tops of the two roller support mechanisms 505 .

[0045] The speed torque sensor 503 is a sensor used to measure the speed and torque of rotating mechanical equipment. It can monitor the operating status of the mechanical equipment in real time and provide key operating parameter information to help monitor and control the performance and safety of the equipment.

[0046] The rotation resistance detection mechanism 5 includes: a second measured roller 502, a speed torque sensor 503, a servo motor 504, a roller support mechanism 505, and a second pressurizing device 506. The second measured roller 502 is placed on the detection platform, and the servo motor 504 drives the driving wheel 401 to rotate, and the friction wheel is lowered to make the roller bear a pressure of 250N. The motor is started, and after the outer circle linear speed of the roller is stabilized and the test time is reached, the rotation resistance reading can be read by the computer.

[0047] The axial displacement detection mechanism 6 includes: a third measured support 602, a support seat 603, a third pressurizing device, a first drive motor 605, a screw 606, and a displacement sensor 607. The third measured support 602 is placed on the detection platform, and the screw 606 is driven by the first drive motor 605 to perform linear motion. By applying axial pressure, one end of the roller is pressed against the fixed plate, and the displacement sensor 607 captures the displacement signal, and the detection value is read by a computer.

[0048] The radial runout detection mechanism 3 includes: a laser sensor 301, a first measured roller 302, a roller fixing mechanism 303, and a first pressurizing device 304. The principle is to rotate the tube body one circle, and measure the radial runout at three axial positions of the roller by the laser sensor 301, and take the maximum value as the basis for evaluation.

[0049] The radial load test mechanism 7 mainly includes: a first tested roller 302, a second drive motor 701, a sliding guide rail 901, a clamping mechanism 9, and a driving wheel 401. The principle is that the servo motor drives the screw rod to slowly apply a radial load to the roller through the driving wheel, and the deformation of the roller is observed when the standard value is reached.

[0050] The noise and vibration detection mechanism 8 of the roller mainly drives the roller to rotate through the driving wheel 401, and the corresponding sensor captures the signal in real time, and its value is displayed on the computer.
