Description

Technical Field

[0001] The invention belongs to the technical field of bearing detection, and in particular relates to a digital full-automatic vibration analyzer. Background Art

[0002] Bearings, as a device used to reduce friction during rotation and support rotational motion, are widely used in various industries and products such as automobiles, machine tools, processing machinery, and engineering machinery. However, during the production process of bearings, various processing defects may cause bearing defects, which will cause unnecessary vibrations during the rotation process. The use of defective bearings will affect the reliability and service life of the equipment. Therefore, bearing manufacturers need to avoid bearing defects as much as possible to improve the yield rate, thereby reducing production costs and improving product quality.

[0003] There are many adverse factors that cause bearing vibration, such as damage to the inner ring, outer ring, and steel ball of the bearing. These factors refer to microscopic bumps and concave spots on the inner groove surface of the outer ring or the outer groove surface of the inner ring, or the surface of the steel ball caused by corrosion, bumps, scratches, and poor surface finish. The vibration generated by this is difficult to detect and judge accurately by humans alone. It requires the use of professional testing equipment to convert the vibration of the bearing into electrical signals and use the system to compare the test data to obtain accurate test results, so as to effectively feedback the production process of the bearing.

[0004] However, most of the devices currently available on the market for detecting and analyzing bearing vibration require manual operation, and can only detect a single bearing at a time. The detection results are still easily affected by human factors, which affects the accuracy of the detection. In addition, manual detection will cause fatigue to personnel when detecting large quantities of bearings, affecting the detection efficiency. At the same time, it is impossible to guarantee the standardization of each detection. Therefore, a device that can automatically detect batches of bearings is needed.

[0005] A Chinese patent with authorization announcement number CN207600743U discloses a fully automatic wheel hub bearing vibration detector, including an instrument platform, a spindle box, a drive device, an axial force device, a measuring device, a pulling device, a material channel and a turning device, a dividing channel device and an operating system and an intelligent analysis system. The spindle box is installed in the middle front part of the platform, the drive device is connected to the spindle through a pulley and a belt, the pulling device sends the bearing from the feed port to the next station in sequence until the measurement is completed to the last dividing channel, the material channel and the turning device are located in the middle of the platform, the turning device turns the bearing 180°, the dividing channel device is used to distinguish qualified bearings from unqualified bearings that have been measured, the operating system and the intelligent analysis system are above the measuring instrument, the operating system controls the action of each component of the measuring instrument, and the intelligent analysis system receives and analyzes the vibration data signal and outputs the bearing determination result.

[0006] However, the above patent still has the following disadvantages:

[0007] 1. According to the description of the above patent, the bearings in the above patent are tested in a horizontal state, which makes the action and structure of clamping and driving the bearing movement more complicated during the feeding and flipping process. The bearings are easy to fall off during the feeding and flipping process, resulting in unstable and continuous testing process, affecting the testing effect and efficiency.

[0008] 2. The above patent only uses a dividing channel device to simply distinguish qualified bearings from unqualified bearings after measurement, and cannot classify and stack the tested bearings, making it difficult to match the tested data with the corresponding bearings. When the bearing manufacturer needs to compare the test data with the corresponding bearing, it is difficult to find the corresponding bearing, which is not convenient for optimizing the production process. Summary of the invention

By setting the stacking components, the bearings after detection can be classified and stacked according to whether they are qualified or not, and the qualified rate of the bearings can be displayed intuitively. The order of the bearings stacked on each stacking slot is consistent with the detection order, which is convenient for users to retrieve the detection data and match it with the corresponding bearing, and then facilitate the comparison and analysis of the bearing and the detection data, and reversely infer the defects and problems in the processing process.

DETAILED DESCRIPTION

[0038] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0039] Embodiment 1:

[0040] like Figure 1-8As shown, a digital fully automatic vibration analyzer includes a body 1, a material pulling component 4 is arranged on the working table of the body 1, two groups of vibration measuring components 2 are arranged at the corresponding positions of the material pulling component 4 on the body 1, the vibration measuring component 2 includes a spindle box 21, a spindle core rod 23 is rotatably connected in the spindle box 21, an axial loading component 24 is arranged at a position opposite to the spindle core rod 23, a servo motor 22 is arranged at one end of the spindle box 21 away from the axial loading component 24, the power of the servo motor 22 is the output end connected to the spindle core rod 23, the axial loading component 24 includes a load applicator 243, the load A pressure plate 244 is fixedly connected to the end of the applicator 243, and a bracket 241 is arranged at a corresponding position of the pressure plate 244. A group of side plates 242 are fixedly connected to both sides of the bracket 241. A plurality of pressure claws 245 are evenly distributed and fixedly connected on the end surface of the pressure plate 244 close to the spindle core rod 23. A sensor assembly 25 is arranged at the upper end of the spindle box 21. The sensor assembly 25 includes a lifting mechanism 251 fixed to the upper end of the spindle box 21. A position adjustment mechanism 252 is symmetrically distributed and fixedly connected to the extended end of the lifting mechanism 251. A sliding and adjustable vibration sensor 253 is arranged on the position adjustment mechanism 252.

[0041] By setting the main shaft core rod 23, the inner ring of the bearing can be driven to rotate, and the vibration sensor 253 abutting against the outer ring of the bearing can be used to convert the vibration of the bearing into detection data and record, store and analyze the data, so that the user can statistically control the production process and production quality of the bearing according to the detection results, trace and adjust the problems and errors in the bearing production process, optimize production, and can be used to sort bearings.

[0042] like Figure 1-8 As shown, an oil dripping assembly 72 for spraying oil and lubricating the inner ring of the bearing is provided at the corresponding position of each group of vibration measuring components 2 on the working table of the body 1, and a grease distribution assembly 71 is fixedly connected to the first conveying rail 41 near the loading component 3, and the power output end of the grease distribution assembly 71 can be connected to the bearing transmission.

[0043] By providing the grease uniforming component 71, the bearing to be tested can be driven to rotate in advance before testing, so that the grease pre-filled in the bearing during production can be more evenly distributed in the bearing. By providing the oil dripping component 72, lubricating oil can be applied to the bearing during the bearing testing process to simulate the lubrication conditions of the bearing in actual use, thereby obtaining more accurate test data when the bearing is tested, thereby improving the accuracy of the test and the authenticity of the data.

[0044] like Figure 1-8As shown, the material pulling component 4 includes a second conveying rail 42, and two symmetrical second conveying rails 42 are fixedly connected on the working table of the body 1 between the two groups of vibration measuring components 2, and a face changing component 43 is arranged between the two second conveying rails 42. Two first conveying rails 41 are respectively arranged on the two sides away from each other of the two groups of vibration measuring components 2. The first conveying rail 41, the second conveying rail 42 and the face changing component 43 and the detection positions of the two vibration measuring components 2 are in the same track, and tooth plates 44 with uniform tooth grooves are movably arranged in the first conveying rail 41 and the second conveying rail 42. Two groups of vertical moving components 45 are fixedly connected on the working table of the body 1. The telescopic end of the vertical moving component 45 is fixedly connected to the transverse moving component 46, and the movable end of the transverse moving component 46 is fixedly connected to the tooth plate 44. A loading component 3 is arranged on the working table of the body 1 at one end of the pulling component 4, and the loading component 3 includes a conveyor belt assembly 31, and a string rod 32 is fixedly connected to the side of the conveyor belt assembly 31 away from the pulling component 4. A first push plate assembly 33 is arranged on the conveyor belt assembly 31 at a position corresponding to the string rod 32, a flipping assembly 35 is arranged at the docking position between the conveyor belt assembly 31 and the pulling component 4, and a second push plate assembly 34 is arranged on the conveyor belt assembly 31 at a position corresponding to the flipping assembly 35.

[0045] The pulling component 4 can be raised and lowered and moved laterally in the first conveying rail 41 and the second conveying rail 42 through the vertical moving component 45 and the horizontal moving component 46, so as to move the bearings in the first conveying rail 41 and the second conveying rail 42 one by one, and automatically transport the bearings to the vibration measuring component 2 for automatic detection. The pulling action of the tooth plate 44 is simple and the feeding effect is stable, which greatly improves the degree of automation of bearing detection, frees up manpower and improves detection efficiency.

[0046] By providing the feeding component 3, the bearings stored on the string rod 32 can be fed into the flip assembly 35 one by one, and the flip assembly 35 can be used to stand up the horizontal bearings, and the pulling action of the tooth plate 44 can be coordinated to realize automatic feeding, further improve the automation of detection, and improve detection efficiency.

[0047] like Figure 1-8As shown, the stacking component 5 includes a stacking plate 51, on which a stacking guide rail 53 is fixedly connected. The stacking guide rail 53 and the first conveying rail 41 are in the same track. A plurality of stacking grooves 52 are evenly distributed on the surface of the stacking plate 51. The semi-digital stacking grooves 52 close to the vibration measuring component 2 are used for carrying unqualified bearings, while the semi-digital stacking grooves 52 away from the vibration measuring component 2 are used for carrying qualified bearings. A detection sensor 57 is fixedly connected at one end of the stacking plate 51 away from the stacking guide rail 53, located below each stacking groove 52. A through blanking groove 54 is provided at the bottom of the stacking guide rail 53 at a corresponding position of each stacking groove 52. A push block 55 is slidably connected in each blanking groove 54. A groove 58 for carrying a bearing is provided on the upper surface of each push block 55. A push cylinder 56 is fixedly connected at a corresponding position of each push block 55 on the stacking groove 52, and the telescopic end of each push cylinder 56 is fixedly connected to the corresponding push block 55.

[0048] By setting up the stacking board 51 and the stacking slot 52, and coordinating the push-pull action of the control push block 55, the bearings after inspection can be classified and stacked to distinguish qualified products from unqualified products. The proportion of unqualified products to the total number of products can be intuitively displayed, which is convenient for calculating the product qualification rate. In addition, the stacking order of the bearings on the stacking slot 52 corresponds to the inspection order one by one, which is convenient for users to retrieve the inspection data and match it with the actual corresponding bearing, and then facilitate reverse inference of the cause of the bearing defect, thereby optimizing the bearing production process.

[0049] In addition, the tested bearings can be neatly arranged and stacked in the stacking slot 52. When the detection sensor 57 detects that the stacking slot 52 is full of bearings, it can notify the user to use a stick-like object to insert the entire row of tested bearings, so as to quickly and conveniently unload the bearings. The order of the removed bearings remains unchanged and they are neatly stacked, which is convenient for subsequent data retrieval, comparison and sample storage.

[0050] like Figure 1-8 As shown, by providing an oil-gas component 6, lubricating oil can be injected into the spindle box 21, so that the spindle core rod 23 can be lubricated during rotation, and the spindle core rod 23 can rotate smoothly to avoid vibration when the spindle core rod 23 rotates, which affects the detection accuracy. Lubricating oil is supplied to the oil drip assembly 72 through the oil-gas component 6 to realize the function of lubricating the bearings of the oil drip assembly 72. The movement of each pneumatic component can be controlled by the oil-gas component 6, so that the device can realize automated detection actions.

[0051] In this embodiment, initially, the user places the device at a designated working position and connects the device to an automatic control system, installs the string rod 32 full of bearings at a designated position, starts the device, and performs an automatic bearing detection process.

[0052] During automatic detection, the first push plate assembly 33 first reciprocates to push the bearing at the lower end of the string rod 32 onto the conveyor belt assembly 31, and the conveyor belt assembly 31 is used to transport the bearing to the second push plate assembly 34. At the same time, the second push plate assembly 34 reciprocates to push the bearings one by one into the flip assembly 35, and the flip assembly 35 continuously flips to erect the bearings one by one, which is convenient for subsequent feeding.

[0053] At the same time, the tooth plate 44 is driven by the vertical moving component 45 and the horizontal moving component 46 to first rise and be lifted, and then move laterally toward the flip assembly 35, and then the tooth plate 44 descends so that the bearing erected by the flip assembly 35 enters the tooth groove of the tooth plate 44, and finally the tooth plate 44 moves laterally away from the flip assembly 35, so that the bearing is separated from the flip assembly 35 and enters the first conveying rail 41, and as the tooth plate 44 repeats the lifting and lateral movement, the bearing slides in the first conveying rail 41 and the second conveying rail 42 and is conveyed in the direction of the two vibration measuring components 2, thereby realizing automatic loading.

[0054] When the bearing is moved by the tooth plate 44 to the corresponding position of the grease equalizing component 71, the power output end of the grease equalizing component 71 is controlled to push into the inner ring of the bearing. At this time, since the outer ring of the bearing is clamped by the tooth plate 44 and the first conveying rail 41, the grease equalizing component 71 can only drive the inner ring of the bearing to rotate, so that the grease pre-applied in the bearing is quickly and evenly distributed in the bearing, avoiding uneven grease from causing unnecessary vibration of the bearing during bearing detection, thereby avoiding affecting the accuracy of bearing detection.

[0055] When the bearing moves to the first group of vibration measuring components 2 under the conveyance of the tooth plate 44, the bearing moves accurately into the groove on the bracket 241, so that the bearing is temporarily restricted on the bracket 241. At this time, the tooth plate 44 is controlled to lift and disengage from the bearing, and the bracket 241 moves toward the direction of the spindle core rod 23, so that the end of the spindle core rod 23 passes through the side plate 242 and finally combines with the inner ring of the bearing. Then the control system controls the lifting mechanism 251 to drive the vibration sensor 253 to move downward until the detection end of the vibration sensor 253 abuts against the outer ring of the bearing, and by controlling the load applicator 243, the multiple pressure claws 245 on the pressure plate 244 are pressed against the outer ring of the bearing, and an axial load is applied to the outer ring of the bearing according to the detection requirements.

[0056] At this time, since the pressure claw 245 limits the rotation of the outer ring of the bearing, the servo motor 22 drives the spindle core rod 23 to drive the inner ring of the bearing to rotate at a speed of 1800rpm. At the same time, the oil drip assembly 72 moves to the vicinity of the bearing to be tested and sprays oil to lubricate the bearing. At the same time, the vibration sensor 253 is used to detect the vibration of the bearing and convert it into an electrical signal. The signal is transmitted to the control system for storage and analysis, and it is determined whether the bearing is qualified.

[0057] During the detection process, according to the detection requirements, the pressure claw 245 and the vibration sensor 253 can be separated from the bearing to release the restriction on the bearing, and then the main shaft core rod 23 is used to drive the entire inner ring to rotate at a low speed, and then the pressure claw 245 and the vibration sensor 253 are controlled to abut against the bearing again, thereby achieving the effect of replacing the outer ring detection point, realizing comprehensive detection data for multiple points, and improving the accuracy and authenticity of the bearing detection data.

[0058] After the bearing is inspected at the first group of vibration measuring components 2, the pressure claw 245 and the vibration sensor 253 are controlled to disengage from the bearing, and the bracket 241 is controlled to reset so that the bearing returns to the tracks of the first conveying rail 41 and the second conveying rail 42. Then the tooth plate 44 conveys the bearing again until the bearing moves to the face changing component 43. The tooth plate 44 rises and disengages from the bearing. At the same time, the face changing component 43 rotates to flip the bearing. Then the tooth plate 44 conveys the bearing to the second group of vibration measuring components 2 again for inspection again, thereby performing a comprehensive inspection of the bearing.

[0059] After the bearing inspection work at the second group of vibration measuring components 2 is completed, the control system records the inspection results and qualified information of the bearings one by one, and the toothed plate 44 transports the inspected bearings to the stacking guide rail 53. At this time, each push block 55 is located in the blanking groove 54. When the bearing marked as qualified by the control system passes through the stacking groove 52 used to carry unqualified bearings, the push block 55 does not move, and the toothed plate 44 continues to transport the bearing until the qualified bearing moves to the designated stacking groove 52. The push cylinder 56 is controlled to pull the push block 55 back so that the qualified bearing falls into the blanking groove 54, and then the push block 55 is controlled to extend outward to push the bearing into the designated stacking groove 52. When the bearing marked as unqualified moves to the stacking groove 52 used to carry unqualified bearings, similarly, the push block 55 is controlled to make the unqualified bearing enter the corresponding stacking groove 52 for stacking.

[0060] As the inspection process proceeds, the bearings on the stacking slots 52 are classified and stacked according to whether they are qualified or not. The user can intuitively understand the proportion of qualified products and unqualified products in the total number of products, thereby deriving the product qualification rate. In addition, the order of the bearings stacked on each stacking slot 52 corresponds to the inspection order one by one, so the user can easily retrieve the inspection data and match it with the corresponding bearing, which is convenient for subsequent analysis of the specified bearing, thereby reversely deducing the problems in the processing and production process, and then optimizing the processing, which has the effect of improving the manufacturer's production efficiency and production quality.

[0061] As the number of bearings stacked on the stacking slot 52 gradually increases, until the bearings are stacked to the end of the stacking slot 52, the detection sensor 57 detects that the number of bearings on the stacking slot 52 has reached the upper limit, and notifies the user to remove the stacked bearings through the control system. The user then uses a stick-like object to penetrate the inner ring of the stacked bearings and string together the entire row of bearings and remove them. The removed bearings are still arranged in the order of their detection, which is convenient for subsequent retrieval and comparison at any time.

[0062] Embodiment 2:

[0063] like Fig. 9 As shown, in this embodiment, the feeding component 3 is replaced with a turntable feeding mechanism, so as to achieve the effect of changing the feeding method according to customer needs and flexibly responding to various detection needs.

[0064] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect.

[0065] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such product or system. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the product or system including the elements.

[0066] The above description shows and describes several preferred embodiments of the present application, but as mentioned above, it should be understood that the present application is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the application concept described herein through the above teachings or the technology or knowledge of the relevant field. The changes and modifications made by those skilled in the art do not deviate from the spirit and scope of the present application, and should be within the scope of protection of the claims attached to the present application.
