Abstract
Description
Technical Field
[0001] This invention relates to the field of bearing technology, specifically to a multifunctional operating platform for bearing fault diagnosis. Background Technology
[0002] Bearings are essential basic components of various mechanical equipment. Their precision, performance, lifespan, and reliability play a decisive role in the precision, performance, lifespan, and reliability of the main machine. Among mechanical products, bearings are high-precision products, requiring comprehensive support from theories of many disciplines such as mathematics and physics.
[0003] In response, Chinese patent application number CN222232055U discloses a multifunctional operating platform for bearing fault diagnosis, relating to the field of bearing testing. The platform includes a diagnostic operating platform with through holes on its upper surface, a positioning component on its surface, and an electronic stethoscope on its upper surface. The positioning component includes a first electric push rod fixedly installed on the lower surface of the platform. By using the positioning component, the bearing is placed on the upper surface of a rotating plate. Then, the electric push rod is activated, causing the peripheral positioning plates to slide outwards and press against the inside of the bearing, thus fixing it in place. Simultaneously, the pressure plate above moves downwards, causing the pressure plate to slide downwards and fix the upper part of the bearing, thereby limiting and fixing the bearing in multiple directions. This allows the device to fix and limit bearings of different sizes, expanding the applicability of the operating platform, improving its inventiveness, and enhancing the positioning effect on the bearing.
[0004] However, existing multi-functional operating platforms for bearing fault diagnosis cannot directly determine whether the bearing has cracks because bearings need to be diagnosed during the production process. This results in poor diagnostic results.
[0005] Therefore, in order to solve the above problems, a multi-functional operating platform for bearing fault diagnosis is proposed. Summary of the Invention
[0006] The purpose of this invention is to provide a multi-functional operating platform for bearing fault diagnosis, in order to solve the problem mentioned in the background art of the prior art for bearing fault diagnosis. Since bearings need to be diagnosed during the production process, the existing devices use ultrasound to diagnose positive faults in bearings. This method cannot directly determine whether there are cracks in the bearing, thus leading to poor diagnostic results.
[0007] To achieve the above objectives, the present invention provides the following technical solution: a multi-functional operating platform for bearing fault diagnosis, comprising: a support leg and a worktable; the worktable is provided at the upper end of the support leg; a positioning mechanism is provided on the worktable; a fixing block is provided inside the positioning mechanism; a support rod is provided on the fixing block; a support ring is provided on the support rod; a bearing body is provided on the support ring; side plates are provided on both sides of the fixing block; a rotating block is provided on one side of the side plate; a threaded rod is provided on the rotating block; a clamping ring is provided at one end of the threaded rod; and a processing mechanism is provided on the worktable; a servo motor is provided inside the processing mechanism; a transmission rod is fixedly installed at the output end of the servo motor via a coupling; a diagnostic component is provided at one end of the transmission rod; the bearing body can be positioned using the positioning mechanism; and the bearing body is positioned by the support rod and support ring within the mechanism. The bearing is supported by a rotating block that drives a threaded rod to rotate, which in turn drives a clamping ring to hold and position the bearing body. A processing mechanism then diagnoses the bearing body. A servo motor drives a transmission rod to rotate, which in turn drives the diagnostic components, causing the pulley to move against the inner ring wall of the bearing. If a crack is found, the spring rod will vibrate, and the vibration force will be transmitted through a transmission rod and a connecting rod to a vibration sensor for reception and recording. The core principle of this vibration sensor is to convert mechanical vibration into a measurable electrical signal. It mainly consists of two parts: mechanical reception and electromechanical conversion. This case uses a relative mechanical reception method: a spring connects the contact rod to the object being measured, and a recording pen plots a vibration curve on a paper tape, reflecting the relative vibration between the object being measured and a reference body, thereby improving the working quality of the device.
[0008] Preferably, the diagnostic component includes a vibration sensor, which is fixedly mounted on the transmission rod. The vibration sensor can detect and record cracks in the bearing body.
[0009] Preferably, connecting rods are fixedly installed on both sides of the vibration sensor, and a transmission rod is fixedly installed at one end of the connecting rod to transmit force to the connecting rod.
[0010] Preferably, a spring rod is fixedly installed at one end of the transmission rod, and a stop plate is fixedly installed at the other end of the spring rod. The spring rod touches the object, thereby causing vibration.
[0011] Preferably, a bracket is fixedly installed on the abutment plate, and a pulley is fixedly installed inside the bracket via a rotating rod. One side of the pulley is in contact with the inner ring of the bearing body, so that the pulley directly contacts the bearing body, thereby transmitting vibration through the pulley and the spring rod.
[0012] Preferably, the fixing block is fixedly installed on the workbench, one end of the support rod is fixedly installed on the fixing block, the support ring is fixedly installed on the support rod by bolts, and the bearing body is placed on the support ring. The fixing block can support the support rod, and the support rod can support the support ring.
[0013] Preferably, the bottom end of the side plate is fixedly mounted on the workbench by bolts, the rotating block is fixedly mounted on the threaded rod, one end of the threaded rod passes through the side plate, and the clamping ring is fixedly connected to the threaded rod through a rotating shaft. One side of the clamping ring is in contact with the outer ring of the bearing body. The rotating block can drive the threaded rod to rotate, and the threaded rod drives the clamping ring to work.
[0014] Preferably, the servo motor is fixedly mounted on the fixed block by bolts, and one end of the transmission rod passes through the support ring and is rotatably mounted on the inner ring of the bearing body. The servo motor can drive the transmission rod to rotate, thereby driving the diagnostic component to rotate.
[0015] Compared with the prior art, the beneficial effects of the present invention are:
[0016] 1. By setting up a positioning mechanism to position the bearing body according to the bearing size, compared with the existing structure, the present invention adopts a structure of fixing block, support rod, support ring, rotating block, threaded rod, clamping ring, etc. The bearing body can be supported by the support ring and clamped and positioned by the clamping ring. This structure is simple and effective, thereby improving the inventiveness of the device.
[0017] 2. By incorporating a processing mechanism, the bearing body can be diagnosed as needed. Compared to existing structures, this invention employs a servo motor, transmission rod, and diagnostic components. The diagnostic components include a vibration sensor, whose core principle is to convert mechanical vibration into a measurable electrical signal. This signal is then connected to the object being tested via a spring-loaded contact rod. A recording pen plots a vibration curve on a paper tape, reflecting the relative vibration between the object being tested and a reference body. This allows for the recording of cracks on the bearing body, thereby identifying whether the bearing body is damaged and improving the device's operational quality. Attached Figure Description

[0037] Working principle: When the multi-functional operating platform for bearing fault diagnosis is needed, the device is supported by the support leg 1 and powered on by the existing power supply. The bearing body 34 can be placed on the support ring 33 as needed. The rotating block 36 drives the threaded rod 37 to rotate. The threaded rod 37 drives the clamping ring 38 to clamp and position the bearing body 34 through the rotating shaft. The servo motor 41 is then started to drive the transmission rod 42 to rotate, thereby driving the diagnostic component 43 to work.
