Description

Technical Field

[0001] This invention relates to the field of bearing testing technology, and specifically discloses a batch testing device for bearing transmission performance. Background Technology

[0002] As a core component in modern machinery, the quality of bearings determines the overall performance of the equipment. The final step in bearing manufacturing is to test the bearing's transmission performance to ensure the quality of the final product delivered to the customer.

[0003] Currently, due to limitations in testing equipment, existing bearing transmission performance testing methods cannot efficiently test batches of bearings. Instead, only random sampling can be used to test the transmission performance of bearings, resulting in inconsistent quality of bearings delivered to customers.

[0004] For example, invention patent application number 2012101082071 discloses a rolling bearing friction torque test bench, including a test bench body, a dual-output shaft motor mounted on the test bench body, and a left detection device and a right detection device respectively connected to the two output shafts of the dual-output shaft motor. The left output shaft of the dual-output shaft motor drives the left transmission shaft to rotate. The left bearing under test is provided with a left bearing under test mounting and fixing device, which includes a left bearing under test outer sleeve. The left bearing under test is axially fixedly fitted on the left transmission shaft and interference-fitted inside the left bearing under test outer sleeve. A left shaft shoulder acting on the outer ring of the left bearing under test is installed on the left bearing under test outer sleeve, and the left shaft shoulder is installed on the left bearing under test outer sleeve through a threaded connection structure. An annular pressure sensor is provided between the left shaft shoulder and the left bearing under test, and a torque sensor is also provided on the left bearing under test outer sleeve. While the rolling bearing friction torque test bench disclosed in the patent achieves the effect of testing bearing transmission performance by detecting the bearing's friction torque, it can only test one or two bearings at a time, resulting in low testing efficiency and making it unsuitable for rapid testing of batches of bearings. Therefore, this application proposes a batch testing device for bearing transmission performance that effectively solves the above-mentioned technical problems, thereby enabling comprehensive testing of bearings and ensuring the quality of the final products sold. Summary of the Invention

[0005] The purpose of this invention is to provide a batch testing device for bearing transmission performance, so as to achieve efficient testing of the transmission performance of batch bearings and realize comprehensive quality inspection of bearing products leaving the factory.

[0006] This invention is achieved through the following technical solution: A batch testing device for bearing transmission performance includes a base and a control box. A feeding mechanism is provided on the upper left side of the base. A receiving seat is provided on the upper surface of the base below the feeding mechanism and moves left and right. A first vertical side plate is provided on the right side plate. A rotating frame that rotates at a fixed angle is provided on the first vertical side plate. At least four key shafts are evenly arranged on the rotating frame in the circumferential direction. The key shafts at the lower end are aligned with the receiving seat. A rubber roller that moves up and down is provided above the key shafts at the top. One end of the rubber roller is connected to a second motor. The upper surface of the base is provided with a second upright side plate, and the second upright side plate is provided with a color marking unit for color marking the bearing to be tested on the rear key bar shaft. The top of the second upright side plate is provided with an industrial camera facing the top key bar shaft, and the industrial camera is electrically connected to the control box.

[0007] The bearing transmission performance batch testing device disclosed in this invention uses a feeding mechanism to place multiple bearings to be tested into a receiving seat, which then transfers them to a keyway shaft at the lower end, where the keyway shaft tightens and fixes them. It is then rotated to align with a color marking unit, which marks the outer ring of the bearing. After marking, it is rotated to the top, positioned below a rubber roller. The rubber roller is then lowered to press against a row of bearings. A second motor is started, causing the row of bearings to rotate synchronously at the same speed under the action of the rubber roller. The rubber roller is then separated from the bearing, allowing the outer ring of the bearing to rotate freely. During this rotation, an industrial camera captures the marked points on the surface. When the marked points stop rotating, it indicates that the outer ring of the bearing has stopped rotating. The duration of the stoppage of the bearing's outer ring rotation indicates the quality of the bearing's transmission performance. After differentiation, the bearings are manually unloaded and, according to their rating, placed into different collection boxes or on a conveyor line.

[0008] As a first specific design of the above scheme, the coloring and marking unit includes a second plate connected to the second upright side plate. A second cylinder is mounted on the second plate, and a connecting rod parallel to the keybar shaft is connected to the end of the second cylinder. A row of coloring pens facing the keybar shaft is mounted on the connecting rod. This design of the coloring and marking unit utilizes the pushing action of the second cylinder to make a row of coloring pens contact a row of bearings on the keybar shaft, thereby achieving the function of point marking.

[0009] As a second specific design of the above scheme, the coloring and marking unit includes an arc-shaped strip plate rotatably connected to the second upright side plate. One end of the arc-shaped strip plate is connected to a third motor, and the arc-shaped strip plate is rotated around the central axis of the rear key shaft under the action of the third motor. A row of guide sleeves is provided on the arc-shaped strip plate, and coloring pens are inserted in the guide sleeves. The ends of the row of coloring pens away from the key shaft are connected to a connecting rod. A spring is connected between the connecting rod and the arc-shaped strip plate, and a guide wheel is provided at the end of the connecting rod. An annular guide groove is formed on the second upright side plate, which interacts with the guide wheel. At least three inwardly recessed portions are evenly formed on the annular guide groove. The above design of the coloring and marking unit allows the arc-shaped strip plate to be driven to rotate by the third motor. During the rotation, the guide wheel interacts with the annular guide groove, and when rotating to each recessed portion, a row of coloring pens approaches the key shaft and marks on its surface. The entire marking unit can make multiple marking points on the outer ring of the bearing by rotating one revolution.

[0010] As a specific design of the above scheme, the feeding mechanism includes a feeding cylinder, the lower surface of which is provided with a row of feeding channels at equal intervals, and the upper surface of the receiving seat is provided with positioning grooves that are aligned with each of the row of feeding channels.

[0011] As a specific design of the above scheme, the upper surface of the machine base is provided with a slide rail, the receiving seat is movably arranged along the slide rail, and a telescopic push rod for pushing the receiving seat to move left and right is provided on the machine base.

[0012] As a specific design of the above scheme, the rotating frame includes a rotating shaft connected to the upper bearing of the first upright side plate. The left end of the rotating shaft is provided with a cross for installing the key bar shaft, and the right end of the rotating shaft is connected to a transmission mechanism consisting of a transmission wheel, a transmission belt and a first motor.

[0013] As a specific design of the above scheme, the top of the second upright side plate is connected to a first plate, the first plate is provided with a first cylinder, the lower end of the first cylinder is connected to a roller seat, the rubber roller is rotatably installed in the roller seat, and the second motor is provided at the side end of the roller seat.

[0014] As a specific design of the above scheme, the control box is equipped with a control module, a timing module and a video processing module inside, and a display screen and control buttons are installed on the outside of the control box.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: The bearing transmission performance batch testing device disclosed in this invention utilizes a rotating frame to achieve rotational switching of multiple keybar shafts. Multiple bearings arranged side-by-side can be simultaneously installed in each keybar shaft. A rubber roller is then used to allow the outer rings of a row of bearings on the keybar shaft to rotate freely. During this free rotation, an industrial camera captures the state in real time until the outer rings of the bearings stop rotating. The duration of free rotation until the bearing outer rings stop is used to determine the quality of the bearing transmission performance. This entire testing device not only uses visual methods to detect bearing transmission performance but also allows for batch testing of bearings each time, greatly improving the testing efficiency.

[0016] The bearing transmission performance batch testing device disclosed in this invention utilizes visual inspection of bearing transmission performance, and also uses a color marking unit to mark the bearing surface with corresponding signals before rotation. These marking signals can then be used to improve the real-time capture and judgment of the bearing status by the industrial camera, thereby improving the accuracy of bearing transmission performance testing. The entire technical solution has a novel design concept and excellent actual testing results. Attached Figure Description

Detailed Implementation

[0019] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0020] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The following will refer to the appendix... Figures 1-7 This application will be described in detail with reference to the embodiments. Example 1

[0021] Example 1 discloses a batch testing device for bearing transmission performance, see attached document. Figure 1 and attached Figure 2 The main body of the detection device includes a base 1 and a control box 2. The control box 2 is equipped with a corresponding control module, timing module and video processing module, while the control box 2 is equipped with a corresponding display screen and control buttons on the outside.

[0022] A feeding mechanism 3 is provided on the upper left of the base 1. Specifically, the feeding mechanism 3 includes a feeding cylinder 301 arranged along the length of the base 1. A row of feeding channels 302 is arranged at equal intervals on the lower right end surface of the feeding cylinder 301, so that a group of bearings to be tested can be sent to the top of the feeding channel 302 under the action of the external pushing mechanism, and then a row of bearings to be tested can be discharged from the corresponding feeding channel 302.

[0023] Reference Appendix Figure 5 A slide rail 4 is provided on the upper surface of the machine base 1 along its length. A receiving seat 5 is slidably mounted on the slide rail 4, located directly below a row of feeding channels 302. The upper surface of the receiving seat 5 has positioning grooves 501 that are aligned with each of the feeding channels 302. A telescopic push rod 6 is also provided at the left end of the upper surface of the machine base 1, and the end of the telescopic push rod 6 is connected to the receiving seat 5, so that the receiving seat 5 can be pushed left and right along the slide rail 4 under the action of the telescopic push rod 6.

[0024] Reference Appendix Figure 3 and attached Figure 4A first vertical side plate 7 is fixedly installed on the upper right surface of the base 1. A bearing is installed at the upper end of the first vertical side plate 7. A rotating frame 8 is rotatably connected to the bearing. The rotating frame 8 includes a rotating shaft 801 connected to the bearing. A cross 802 is connected to the left end of the rotating shaft 801. A key bar shaft 9 with one end suspended is fixedly connected to each of the four ends of the cross 802. The four key bar shafts 9 are evenly arranged in a circular array with the rotating shaft 801 as the center. At the same time, the axial key bar on the outer circular surface of the key bar shaft 9 can actively expand outward or contract inward, thereby tightening and fixing the bearing to be tested that is fitted onto the key bar shaft 9. In addition, a transmission mechanism is connected to the right end of the rotating shaft 801. The transmission mechanism includes a first motor 10. Both the first motor 10 and the right end of the rotating shaft 801 are provided with transmission wheels 11. Then, a transmission belt 12 is provided between the two transmission wheels 11, so that the cross 802 can rotate 90° each time under the action of the first motor 10 and the transmission belt 12, thereby realizing the precise switching of the key bar shaft 9 station.

[0025] A first strip 13 parallel to the key bar shaft 9 is provided at the top of the first upright side plate 7. A first cylinder 14 is provided at the upper end of the first strip 13. Of course, the first cylinder 14 can also be replaced by other telescopic drive components. A roller seat 15 is connected to the lower end of the first cylinder 14. A rubber roller 16 aligned with the key bar shaft 9 at the top is rotatably connected in the roller seat 15. A second motor 17 mounted on the roller seat 15 is connected to one side end of the rubber roller 16.

[0026] Reference Appendix Figure 2 A second side plate 18, fixed to the upper surface of the base 1, is provided at the left end behind the first side plate 7. A coloring and marking unit 19 for coloring and marking the bearings to be tested on the rear key shaft 9 is provided on the second side plate 18. The coloring and marking unit 19 in this embodiment 1 includes a second strip plate 20 fixed to the rear side of the second side plate. A second cylinder 21 is installed on the second strip plate 20. A connecting rod 22 parallel to the key shaft 9 is connected to the end of the second cylinder 21. A row of coloring pens 23 aligned with the bearings to be tested on the key shaft 9 is provided on the connecting rod 22. Under the action of the second cylinder 21, the connecting rod 22 and the coloring pens 23 are pushed towards the rear key shaft 9. Then, a coloring dot is drawn on the outer surface of the row of bearings to be tested as a mark by the coloring pen 23.

[0027] Finally, a third plate 30 is provided at the upper end of the second side plate, which is aligned with the top key axis 9. An industrial camera 31 is mounted on the third plate 30 and faces the top key axis 9. The industrial camera 31 is electrically connected to the video processing module inside the control box 2.

[0028] In this embodiment 1, the batch testing device for bearing transmission performance is used to test the transmission performance of a large number of bearings. Each time, a group of bearings to be tested is dropped and transported from the unloading mechanism 3 to the positioning groove 501 of the receiving seat 5. Then, the telescopic push rod 6 is activated to push the receiving seat 5 toward the key bar shaft 9 at the bottom until a group of bearings to be tested is fitted into the key bar shaft 9. Then, the key bar shaft 9 is used to tighten and fix the group of bearings to be tested. After fixing, the key bar shaft 9 and the bearings to be tested are rotated 90° under the action of the transmission mechanism so that they are aligned with the front and back of the color marking unit 19.

[0029] Next, the coloring and marking unit 19 is activated, and the second cylinder 21 pushes a row of coloring pens 23 toward the key shaft 9, marking each bearing's outer surface with a colored dot. After marking, the transmission mechanism is activated to rotate the key shaft 9, along with the bearings to be tested, by 90°, until it reaches the top and aligns with the rubber roller 16. Then, the first cylinder 14 is activated to push the rubber roller 16 downwards, pressing it onto a group of bearings to be tested. The second motor 17 is then activated to drive the rubber roller 16 to rotate, causing all the bearings to be tested to rotate synchronously at the same speed. Finally, the first cylinder 14 is retracted, separating the rubber roller 16 from the bearings. At the instant of separation, the industrial camera 31 is activated to capture an image of the rotating bearing's outer surface.

[0030] When the lens of industrial camera 31 detects that one or more bearing outer rings have not been marked with colored markers for a certain time interval, or that the colored markers remain stationary, it can be determined that the bearing outer rings are nearing a stop. The duration of this stop can then be used to assess the bearing's transmission performance. Finally, after the inspection is complete, the entire keyway shaft 9 is rotated 90° to the unloading hole position. At this point, the operator can view the quality of a row of bearings on the display screen on control box 2. During the unloading process, the bearings are then placed into different collection boxes or onto the conveyor line according to their respective ratings. Example 2

[0031] Example 2 discloses a batch testing device for bearing transmission performance that is further improved based on Example 1. It mainly addresses the issue that the color marking unit in Example 1 can only mark one color dot on the outer ring of the bearing each time, which makes it impossible to more accurately judge the static state during the bearing testing process.

[0032] The similarities between Example 2 and Example 1 will not be repeated here; please refer to the appendix. Figure 6 and attached Figure 7In this embodiment 2, the color marking unit 19 includes an arc-shaped strip 24 rotatably connected to the left side of the second side plate 18, and the central axis of rotation of the arc-shaped strip 24 coincides with the key bar shaft 9 on the rear side. Then, a third motor 25 for driving the arc-shaped strip 24 is provided on the left side of the second side plate 18.

[0033] A set of guide sleeves 26 are provided on the arc-shaped strip 24, aligned with the bearing to be tested on the key bar shaft 9. A coloring pen 23 is inserted into each guide sleeve 26. A connecting rod 22 is connected to the end of the set of coloring pens 23 away from the key bar shaft 9. A spring 27 is connected between the connecting rod 22 and the arc-shaped strip 24. In addition, a guide wheel 28 is connected to the end of the connecting rod 22 near the second upright side plate 18. An annular guide groove 29 with the rear key bar shaft 9 as the center is opened on the right side of the arc-shaped strip 24. The annular guide groove 29 has at least three inwardly recessed portions 291 evenly opened in the circumferential direction. The guide wheel 28 is then extended into the annular guide groove 29 and guided there.

[0034] In the operation of the color marking unit 19 disclosed in Embodiment 2, the key bar shaft 9, which is fixed with a set of bearings, is first rotated to the color marking station on the rear side. Then, the third motor 25 is started to make the arc-shaped bar 24 rotate one revolution. During the rotation of the arc-shaped bar 24, the coloring pen 23 and the connecting rod 22 will rotate synchronously. At this time, due to the action of the annular guide groove 29 on the guide wheel 28, whenever the guide wheel 28 rotates and moves to the concave part 291, the set of coloring pens 23 will move towards the key bar shaft 9 under the action of the spring 27, and the coloring pen 23 will draw a mark on the outer ring of the bearing to be tested. In this way, one revolution can evenly draw multiple color marking points on the outer ring of the bearing to be tested. The presence of multiple color marking points can enable the subsequent industrial camera 31 to have higher judgment accuracy in the detection and judgment process.

[0035] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
