Description

Technical Field

[0001] The present invention relates to the technical field of bearing detection, and particularly to a bearing load testing machine and a testing method. Background Art

[0002] Bearing load detection includes axial load detection and longitudinal load detection of the bearing. During the bearing load detection process, the bearing needs to be placed in the bearing load detection equipment, and while ensuring the center of the bearing is in a determined state, radial load detection is carried out along the determined center of the bearing, and at the same time, radial load detection is carried out on the bearing, so as to ensure the output quality of the bearing products.

[0003] Chinese Patent CN109822376A discloses a flange-type bearing housing automatic centering and clamping mechanism, including a bracket, a pressing device and a bearing housing. A track plate is assembled in the middle of the top surface of the bracket. The pressing device includes a cylinder, a first lever and a frame. A U-shaped block is installed on the piston rod of the cylinder. U-shaped seats are installed on both sides of the top surface of the bracket. An active block is hinged between the U-shaped block and the U-shaped seat. The inner end of the first lever is assembled and connected to the active block. A positioning taper pin is provided on the bottom surface of the outer end of the first lever. Through grooves are provided on both the track plate and the middle of the top surface of the bracket. A fixing ring is assembled at the bottom slot opening of the through groove. A resilient ring is assembled on the bottom surface of the fixing ring. Springs are distributed between the resilient ring and the fixing ring. A centering ring is provided in the inner cavity of the resilient ring.

[0004] However, in this technical solution, although axial locking can be achieved by using the positioning taper pin to cooperate with the mounting hole, and radial locking can be achieved by using the centering ring to cooperate with the stop groove, the centering process is relatively complex, and due to the low accuracy of the mechanical locking axis core, the bearing is likely to be worn due to mechanical errors during centering. Summary of the Invention

[0005] The purpose of the present invention is to address the deficiencies of the prior art and provide a bearing load testing machine and a testing method. Through the feeding component, each group of bearings to be tested on one side of the baffle are loaded and passed over the baffle to reach the side of the detection component. The axial detection component continuously guides the bearings to be tested through the feeding channel formed between the machine base and the radial detection component onto the positioning shaft and locks them. The axial detection component continues to apply force to conduct axial load detection on the bearing. The radial detection component conducts detection on the bearing to be tested. At the same time, the material moving component discharges the bearings that have been tested before. The blanking component pushes out the bearings that have completed the detection to the corresponding loading space for discharging the bearings. Then, the blanking component returns to the side of the baffle again to load the bearings to be tested. This process is repeated, thus solving the technical problems described in the background art.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A bearing load testing machine includes a machine base. It is characterized in that it further includes: a detection component for positioning the bearing load performance, which is installed on the machine base; and a feeding component for centering and transferring the bearing to the detection component, which is arranged on one side of the detection component. The feeding component includes: a material transfer component; and a self-centering component for adaptively adjusting the bearing and continuously centering and guiding, which is distributed between the material transfer component and the detection component. The detection component pushes the bearing that has completed the detection to the material transfer component. The material transfer component reciprocates to transport the bearing to be tested to one side of the detection component and push out the bearing that has completed the detection. The bearing to be tested makes adaptive adjustments on the self-centering component, and after the axis of the bearing is adaptively adjusted by the self-centering component, it is continuously centered to the detection component for installation and detection.

[0008] Further, the self-centering component includes: a feeding channel arranged along the moving path of the bearing to be tested; and a centering component, and several groups of the centering components are continuously arranged on the feeding channel.

[0009] Further, the centering component is arranged in the lower half of the feeding channel.

[0010] Further, the centering component includes: a guiding seat symmetrically arranged on both sides of the feeding channel; and guiding members, and the guiding members evenly distributed along the length direction of the guiding seat are rollingly installed on the guiding seat; the tops of the guiding members protrude from the guiding seat.

[0011] Further, the material transfer component includes: a feeding channel arranged on the machine base; a baffle member for blocking the bearings to be tested arranged in sequence, which is installed at one end of the feeding channel; and a material transfer body component, and the material transfer body component with several loading spaces opened at the top slides in the feeding channel; the centering component is installed in the loading space; the material transfer body component reciprocally lifts the bearing to be tested over the baffle member and pushes it to one side of the detection component, and discharges the bearing that has completed the detection to the feeding channel.

[0012] Further, the centering component is also sequentially distributed on the machine base and the detection component on both sides of the feeding channel.

[0013] Further, the material transfer body component includes: a material transfer body; a pushing component with its power end connected to the material transfer body, which is installed on the machine base; and a lifting component for lifting the material transfer body, which is arranged at the bottom of the machine base.

[0014] Further, the detection assembly includes: a driving assembly on which a positioning shaft is mounted; a radial detection assembly disposed below the positioning shaft with its top flush with the surface of the self-centering assembly; an axial detection assembly disposed at the end side of the positioning shaft for pushing the bearing under test on the material transfer assembly towards the positioning shaft and performing axial bearing force detection; and a blanking assembly mounted on both sides of the radial detection assembly for pushing the bearing that has completed the detection out of the positioning shaft.

[0015] Further, the positioning shaft includes: a main shaft with a conical structure at its end; a supporting member slidably disposed at the end of the main shaft with a circumferentially uniform arrangement; and a pulling assembly passing through the main shaft and connected to the supporting member.

[0016] The present invention also provides a bearing force test method for a bearing force testing machine, including the following steps:

[0017] Step 1: Bearing loading. The material transfer body assembly reaches one side of the material blocking member to load the bearing under test, and crosses the material blocking member to convey the bearing under test to one side of the detection assembly, so as to form a feeding channel among the machine base, the material transfer body, and the detection assembly.

[0018] Step 2: Bearing centering and installation. The bearing under test adaptively cooperating with the corresponding centering assembly is pushed by the axial detection assembly along the feeding channel to be continuously centered and sent to the positioning shaft to complete locking.

[0019] Step 3: Bearing detection. After Step 2, the axial detection assembly continues to apply axial force for axial bearing force detection, and at the same time, the radial detection assembly applies radial force to complete radial bearing force detection.

[0020] Among them, during Step 3, the material transfer body assembly continues to move to discharge the bearing that has completed the detection in the previous group to the material conveying channel and return to one side of the material blocking member to complete material taking.

[0021] Step 4: Unloading. The blanking assembly pushes the bearing that has completed the detection to the corresponding position where the bearing on the material transfer body assembly is discharged, and the material transfer body assembly loads the bearing under test again and reaches one side of the detection assembly.

[0022] Steps 1 to 4 are cycled to sequentially detect the bearings under test arranged on one side of the material blocking member.

[0023] The beneficial effects of the present invention are as follows:

[0024] (1) Through the joint cooperation between the material conveying assembly and the detection assembly, the present invention loads the bearings under test one by one to one side of the detection assembly by the material conveying assembly, and the detection assembly quickly installs the bearings under test that have been continuously centered by the material conveying assembly, and performs radial and axial bearing force detection after installation.

[0025] (2) Through the coordinated cooperation between the material transfer component and the self-centering component, the detection component pushes the bearings after detection to the material transfer component. The material transfer component discharges the bearings and loads the bearings to be tested onto the self-shaping component. Through the feeding channel formed by the machine base, the material transfer component, and the centering components on the detection component, the bearings to be tested are continuously centered and guided to the detection component, ensuring the high efficiency of the positioning shaft penetrating the bearings to be tested.

[0026] (3) Through the structural cooperation between the guide seat and the guide member, the bearings to be tested falling into the centering component will, under the rolling action of the guide member, enable the bearings to be tested to quickly adapt to the feeding channel, thus ensuring the accuracy during the continuous centering of the bearings to be tested.

[0027] (4) Through the mutual cooperation between the material blocking member, the material conveying channel, and the material transfer body component, the material transfer body component on one side of the material blocking member lifts the groups of bearings to be tested arranged in sequence. When it reaches one side of the detection component, it automatically drops to the corresponding height of the feeding channel to complete the guiding of the bearings to be tested. Before returning, it continues to lift the bearings that have been tested to one side of the material conveying channel and then drops to discharge the materials, realizing the synchronous processing of discharging the bearings that have been tested and introducing the bearings to be tested.

[0028] (5) Through the mutual cooperation between the positioning shaft and the radial detection component, while the radial detection of the bearings to be tested can be completed by applying force from the bottom of the bearings, further guiding can be realized when the bearings to be tested transferred by the centering component are sleeved on the positioning shaft through the top surface of the radial detection component.

[0029] (6) Through the mutual cooperation between the axial detection component and the positioning shaft, not only can the axial force detection of the bearings installed on the positioning shaft be realized through the axial detection component, but also the bearings to be tested can be pushed along the transfer channel onto the positioning shaft from the material transfer component.

[0030] (7) Through the mutual cooperation between the main shaft and the supporting member, after the bearings to be tested are inserted onto the positioning shaft, the reciprocating traction component makes the supporting member slide along the conical surface of the main shaft, thereby tightly supporting and fitting the inner surface of the inserted bearings to be tested, realizing the rapid and stable installation of the bearings to be tested.

[0031] In summary, the present invention is applicable to the continuous centering and installation of bearings during bearing force detection, the continuous guiding of bearings, and the accurate centering position of bearings. BRIEF DESCRIPTION OF THE DRAWINGS

Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "a plurality" means two or more unless otherwise specifically defined.

[0045] Embodiment 1

[0046] As Figure 1 shown, a bearing load-bearing testing machine includes a machine base 1, and further includes:

[0047] A detection component 2 for positioning the bearing load-bearing performance, and the detection component 2 is installed on the machine base 1; and

[0048] A feeding component 3 for centering and transferring the bearing to the detection component 2, and the feeding component 3 is arranged on one side of the detection component 2;

[0049] The feeding component 3 includes:

[0050] A material transfer component 31; and

[0051] A self-centering component 32 for adaptively adjusting the bearing and continuously centering and guiding, and the self-centering component 32 is distributed between the material transfer component 31 and the detection component 2;

[0052] The detection component 2 pushes the bearing that has completed the detection to the material transfer component 31. The material transfer component 31 reciprocates to transport the bearing to be tested to one side of the detection component 2 and push out the bearing that has completed the detection. The bearing to be tested makes an adaptive adjustment on the self-centering component 32, and after the axis of the bearing is adaptively adjusted by the self-centering component 32, it is continuously centered to the detection component 2 for installation and detection.

[0053] It is not difficult to find from the above that during the compressive capacity detection of the bearing, the detection component 2 will first push out the bearings that have been detected by it onto the material conveying component 3. The material conveying component 3 carries the bearings that have completed the detection and moves towards the side of the bearings to be detected arranged in sequence for loading the bearings to be detected. After the loading is completed, it is transferred to the side of the detection component 2. The detection component 2 guides and installs the loaded bearings to be detected along the centering direction of the material conveying component 3. After the installation is completed, the material conveying component 3 pushes out the bearings that have completed the detection on the material conveying component 3. Subsequently, the empty material conveying component 3 continues to reach the bearing loading area for loading the bearings to be detected. At the same time, the detection component 2 pushes out the bearings that have completed the bearing force detection onto the material conveying component 3 again, and so on. Specifically, during the process of conveying the bearings by the material conveying component 3, the transfer component 31 carries the bearings to be detected onto the self-centering component 32 on the side of the detection component 2. And the bearings to be detected will complete the self-adaptive centering adjustment on the self-centering component 32. And through the pushing action of the detection component 2, they are continuously self-adaptively centered and guided along the centering and guiding direction of the self-centering component 32, and after completing the centering installation on the detection component 2, the bearing force detection is carried out.

[0054] As Figure 3 shown, the self-centering component 32 includes:

[0055] The feeding channel 321 arranged along the moving path of the bearings to be detected; and

[0056] The centering component 322, and several groups of the centering components 322 are continuously arranged on the feeding channel 321.

[0057] In this embodiment, when the bearings to be detected are centered and guided and installed on the detection component 2 through the self-centering component 32, the detection component 2 will center and guide the bearings to be detected sent through the centering component 322, so that the bearings are continuously guided and positioned along the arrangement direction of the feeding channel 321 and then installed.

[0058] As Figure 3 shown, the centering component 322 is arranged in the lower half of the feeding channel 321.

[0059] In this embodiment, by installing the centering component 322 in the lower half of the feeding channel 321, when the bearings move on the centering component 322 under the action of gravity, they can fully contact the centering component 322, so as to accurately complete the centering installation during the bearing detection.

[0060] As Figure 3 shown, the centering component 322 includes:

[0061] The guiding seats 3221, and the guiding seats 3221 are symmetrically arranged on both sides of the feeding channel 321; and

[0062] The guiding members 3222 are evenly distributed along the length direction of the guiding seat 3221 and are rotatably installed on the guiding seat 3221.

[0063] The top of the guiding member 3222 protrudes from the guiding seat 3221.

[0064] In this embodiment, the guiding member 3222 is preferably a spherical structure. By using the guiding member 3222 on the guiding seat 322 to contact the bearing, and when the detection component 2 pushes and installs the bearing on the material transfer component 31, the bearing to be measured will be pushed along the guiding direction of the guiding seat 322. At the same time, the bearing will also rollingly contact the guiding member 3222, so as to realize the centering of the bearing to be measured during the movement on the guiding seat 3221.

[0065] It should be added that the guiding seat 3221 is transversely provided with an installation space 32221 for installing the guiding member 3222. A spacer 32222 is arranged in the installation space 32221 between adjacent guiding members 3222, and the radial dimension of the spacer 32222 is smaller than the radial dimension of the guiding member 3222.

[0066] As Figure 7 and 10 shown, the material transfer component 31 includes:

[0067] A material conveying channel 311, and the material conveying channel 311 is arranged on the machine base 1.

[0068] A material blocking member 312 for blocking the bearings to be measured arranged in sequence. The material blocking member 312 is installed at one end of the material conveying channel 311; and

[0069] A material transfer body component 313, and the material transfer body component 313 with a plurality of assembly loading spaces 3131 opened at the top is slidably arranged in the material conveying channel 311.

[0070] The centering component 322 is installed in the loading space 3131.

[0071] The material transfer body component 313 reciprocally lifts the bearing to be measured over the material blocking member 312 and pushes it towards the detection component 2 side, and discharges the bearings that have completed the detection to the material conveying channel 311.

[0072] In this embodiment, during the process of transferring the bearings by the material transfer assembly 31, the detection assembly 2 will push the bearings that have completed the detection into the loading space 3131 on one side of the material transfer body assembly 313. Subsequently, the material transfer body assembly 313 carries the bearings that have completed the detection to the bearing loading area, and picks up materials through the loading space 3131 on one side of another set of arrival stop members 312. The material transfer body assembly 313 then pushes the bearings to be tested picked up along the continuous centering and guiding direction of the centering assembly 322 and installs them on the detection assembly 2. And during the guiding process, the bearings to be tested will be lifted over the stop member 312 and sent to the corresponding side of the detection assembly 2. At the same time, after the guiding is completed, the material transfer body assembly 313 continues to move to one side of the material conveying channel 311 to unload the bearings that have completed the detection from the loading space 3131. Subsequently, the empty material transfer body assembly 313 in the loading space 3131 continues to return to one side of the stop member 312 to reload the bearings to be tested for detection.

[0073] It should also be added that the material transfer assembly 31 further includes separation seats 314 arranged on both sides of the material transfer body assembly 313.

[0074] In this embodiment, after the detection assembly 2 pushes and installs the bearings to be tested transferred by the material transfer body assembly 313 on one side thereof, the moving body assembly 313 will continue to lift the bearings that have completed the detection in another set of loaded spaces 3131 that have completed centering above the separation seat 314 and then move them downward, so that the separation seat 314 supports the falling bearings that have completed the detection, thereby realizing the separation of the bearings from the moving body assembly 313. Thus, after the bearings that have completed the detection are separated, the moving material assembly 313 continues to move to the loading area on one side of the stop member 312 to reload the bearings to be tested through the loading space 3131. At the same time, the detection assembly 2 pushes another set of bearings that have completed the detection onto the material transfer body assembly 313 and then pushes them out to the separation seat 314, and so on, to realize the rapid guiding of the bearings.

[0075] It should also be added that a recessed space 3141 adapted to the falling bearings is provided on one side of the separation seat 314.

[0076] In this embodiment, when the bearings to be tested are pushed and installed by the detection assembly 2, the bearings that have completed the detection will temporarily enter the recessed space 3141 on one side of the separation seat 314 for storage.

[0077] As Figure 3 shown, the centering assemblies 322 are also sequentially distributed on the machine base 1 and the detection assembly 2 on both sides of the material conveying channel 311.

[0078] In this embodiment, the centering component 322 within the loading space 3131 for the bearing to be measured is pushed to one side of the detection component 2 after one-time centering, and the centers of the centering component 322 on the loading space 3131 are made to coincide with the centers of the centering component 322 on the frame 1 and the detection component 2 respectively. Thus, the bearing is centered simultaneously by the centering component 322 on the loading space 3131, the centering component 322 on the frame 1, and the centering component 322 on the detection component 2. Subsequently, the detection component 2 pushes the bearing to be measured out from the centering component 322 within the loading space 3131, and the bearing to be measured is pushed and installed onto the detection component 2 along the guiding wire of the centering component 322 between the frame 1 and the detection component 2.

[0079] As Figure 9 shown, the material transfer body assembly 313 includes:

[0080] A material transfer body 3132;

[0081] A pushing component 3133, with its power end connected to the material transfer body 3132, and the pushing component 3133 is installed on the machine base 1; and

[0082] A jacking component 3134 for lifting the material transfer body 3132, and the jacking component 3134 is arranged at the bottom of the machine base 1.

[0083] In this embodiment, when the material transfer body assembly 313 performs the actions of lifting and reciprocating pushing of the bearing, the pushing component 3134 pushes the material transfer body 3132 to the loading area on one side of the baffle 312 for loading. Subsequently, the jacking component 3134 pushes the material transfer body 3132 upwards, causing the material transfer body 3132 to rise above the baffle 312. Then, the pushing component 3134 continues to push the material transfer body 3132 to one side of the detection component 2. After that, the jacking component 3134 moves the material transfer body 3132 downwards to the corresponding installation height of the detection component 2. And after the bearing to be measured is pushed to the detection component 2, the jacking component 3134 continues to lift the material transfer body 3132 to rise above the separation seat 314. Subsequently, the material transfer body 3132 is moved downwards, enabling the bearing that has completed the detection to be separated from the material transfer body 3132 on the separation seat 314.

[0084] It should be added that the pushing component 3134 includes a pushing motor installed on the machine base 1 with its power end connected to the bottom of the material transfer body 3134, and the pushing motor is preferably a push rod motor.

[0085] It also should be added that the jacking component 3134 includes a jacking motor 3134 and a guide wheel 31341 installed on the power end of the jacking motor 3134 and in contact with the bottom of the material transfer body 3132.

[0086] In this embodiment, when the lifting motor 3134 pushes the material moving body 3132 upward, by using the guide wheel 31341 to contact and lift the bottom of the material moving body 3132, the movement interference during the pushing of the material moving body 3132 by the pushing component 3134 is solved.

[0087] Embodiment 2

[0088] As Figure 1 shown, the same or corresponding components as those in Embodiment 1 are labeled with the corresponding reference numerals in Embodiment 1. For simplicity, only the differences from Embodiment 1 will be described below. The differences between this Embodiment 2 and Embodiment 1 are as follows:

[0089] The detection component 2 includes:

[0090] A driving component 21, on which a positioning shaft 211 is installed;

[0091] A radial detection component 22, the radial detection component 22 with its top surface flush with the surface of the self-centering component 32 is arranged below the positioning shaft 211;

[0092] An axial detection component 23, the axial detection component 23 for pushing the bearing to be tested on the material moving component 31 towards the positioning shaft 211 and performing axial bearing force detection is arranged at the end side of the positioning shaft 211; and

[0093] A blanking component 24 installed on both sides of the radial detection component 22 and used to push the completed tested bearing out of the positioning shaft 211.

[0094] In this embodiment, when the detection component 2 pushes, installs and detects the bearing to be tested through the material conveying channel 311, it will first use the axial detection component 23 to continuously center and send the bearing to be tested on one side of the positioning shaft 211 through the feeding channel 321 to the positioning shaft 211, and after positioning and installing through the positioning shaft 211, the radial detection component 22 arranged below the positioning shaft 211 will move upward to apply a force in the radial direction along the bottom of the bearing to be tested for bearing force detection. And after the radial bearing force detection is completed, the blanking component 24 will push the bearing on the positioning shaft 211 along the feeding channel 321 to the material moving component 31, and then discharge the material moving component 31.

[0095] It should be noted that when the bearing to be tested enters the positioning shaft 211 along the feeding channel 321 through the axial detection component 23, the radial detection component 22 with the same surface height as the surface of the self-centering component 32 will position and guide the bearing to be tested.

[0096] It should be added that the radial detection assembly 22 includes a radial push seat 221 connected to the self-centering assembly 32 and a radial push motor 222 arranged below the radial push seat 221; wherein, the radial push motor 222 is preferably a cylinder.

[0097] It also needs to be added that, as Figure 1 shown, the axial detection assembly 23 includes a guide seat 231 installed on the machine base 1 and a push member 232 slidably arranged on the guide seat 231.

[0098] In this embodiment, by means of the push member 232 reciprocatingly moving along the guiding direction of the guide seat 231 to process the bearing, not only can the bearing to be measured be pushed onto the positioning shaft 211, but also after the bearing to be measured is positioned on the positioning shaft 211, the axial bearing force of the bearing to be measured can be detected.

[0099] More specifically, as Figure 4 shown, the blanking assembly 23 includes blanking push members 241 arranged on both sides of the positioning shaft 211, a blanking motor 242 with its power end connected to the blanking push member 241 and installed on the machine base 1, and a guiding member 243 slidably passing through the blanking push member 241.

[0100] In this embodiment, driven by the blanking motor 242, which is preferably a cylinder, the blanking push member 241 can be driven along the guiding direction of the guiding member 243 to push out from one side of the bearing that has completed the detection on the positioning shaft 211.

[0101] Next, as Figure 2 and 4 shown, the driving assembly 21 includes a driving seat 212 arranged on the machine base 1 for installing the positioning shaft 211, a driving motor 213 arranged on one side of the driving seat 212, a driving disc 215 installed on the positioning shaft 211, and a transmission belt 214 for drivingly connecting the driving disc 215 and the driving motor 213.

[0102] In this embodiment, the driving motor 213, which is preferably a servo motor, drives the driving disc 215 through the transmission belt 214, thereby driving the positioning shaft 211 to rotate for radial bearing force detection in the circumferential direction.

[0103] As Figure 6 shown, the positioning shaft 211 includes:

[0104] a main shaft 2111 with a conical structure at the end;

[0105] a supporting member 2112, and the circumferentially uniformly arranged supporting members 2112 are slidably arranged at the end of the main shaft 2111;

[0106] The pulling assembly 2113 passes through the main shaft 2111 and is connected to the top supporting member 2112 .

[0107] In this embodiment, when the positioning shaft 211 is installing the bearing to be tested with the centering sleeve, the power of the pulling component 2113 is used to pull the support member 2112 back and forth along the conical end surface of the main shaft 2111, so that the support member 2112 is stretched and pressed tightly against the inner ring wall of the bearing, thereby realizing the installation of the bearing to be tested.

[0108] It should be supplemented that the pulling member 2113 includes a pulling seat 21131 installed on the supporting member 2112, a pulling rod 21132 sliding through the main shaft 2111 and connected to the pulling seat 21131, and a pulling motor 21133 installed on the end of the main shaft 2111.

[0109] In this embodiment, the pulling rod 21132 is driven to move back and forth on the main shaft 2111 by the pulling motor 21133, which is preferably a cylinder, so that the pulling seat 21131 pulls the support member 2112 toward the inner ring wall of the bearing to be tested to support or loosen it, thereby realizing the installation and disassembly of the bearing to be tested.

[0110] Embodiment 3

[0111] like Figure 11 As shown, the present invention also provides a bearing load test method, comprising the following steps:

[0112] Step 1: Loading the bearing: the material moving body assembly 313 arrives at the side of the material stopper 312 to load the bearing to be tested, and passes over the material stopper 312 to transport the bearing to be tested to the side of the detection assembly 2, so that a feeding channel 321 is formed between the machine base 1, the material moving body 3132 and the detection assembly 2;

[0113] Step 2: Bearing centering installation: the bearing to be tested that is adaptively matched with the corresponding centering component 322 is pushed by the axial detection component 23 and continuously centered along the feeding channel 321 to the positioning shaft 211 to complete locking;

[0114] Step 3: Bearing detection: After step 2, the axial detection component 23 continues to apply axial force to perform axial load-bearing detection, while the radial detection component 22 applies radial force to complete radial load-bearing detection;

[0115] In the process of step 3, the material moving body assembly 313 continues to move to discharge the bearings of the previous group that have completed the inspection to the material delivery channel 311 and returns to the side of the material blocking member 312 to complete the material removal;

[0116] Step 4: Unloading. The blanking component 24 pushes the bearings that have completed the inspection to the corresponding position where the bearings on the material transfer body component 313 are discharged. The material transfer body component 313 loads the bearings to be inspected again and reaches the side of the inspection component 2.

[0117] Steps 1 to 4 are cycled to sequentially inspect the bearings to be inspected arranged on one side of the baffle 312.

[0118] It should be noted that during the process of the material transfer body component 313 discharging the bearings that have completed the inspection to the material conveying channel 311, it also includes:

[0119] After the material transfer body component 313 loads the bearings that have completed the inspection of the previous group and lifts them above the separation seat 314 and then vertically moves downwards so that the bearings reach the separation seat 314, the material transfer body component 313 continues to return to one side of the baffle 312 to load the bearings to be inspected.

[0120] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
