Description

Technical Field

[0001] The present invention relates to the field of bearing processing technology, and specifically to an automotive bearing processing system based on the Industrial Internet. Background Art

[0002] A bearing is a mechanical part that is designed to reduce the friction generated during rotation, effectively ensuring the smoothness and stability of rotation and the service life of related components. Usually, bearings include ball bearings, which include an inner ring, an outer ring and balls. The outer ring is fixed, the inner ring is used for rotation, and the balls are used to reduce friction.

[0003] During bearing processing, the outer ring needs to be fixed, and then the inner ring is sleeved inside the outer ring, and then the balls are filled in and the bearing end cover is gravity pressed to achieve the relative position limitation of the inner and outer rings, and ensure that the balls and the inner ring will not fall off the outer ring. The bearings formed in the above gravity pressing process are prone to defective products due to the effect of heavy pressure or due to irregularities in the processing process, which affects the overall production efficiency of the bearings.

[0035] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0036] See also Figure 1-10As shown, an automotive bearing processing system based on the industrial Internet includes a fixed cylinder 5 and a rotating cylinder 3, wherein the fixed cylinder 5 is fixed at a fixed position, the fixed cylinder 5 and the rotating cylinder 3 are rotatably connected through a rotating seat 4, and the fixed cylinder 5 and the rotating cylinder 3 are connected, and the fixed cylinder 5 and the rotating cylinder 3 are hollow structures. By utilizing the rotatable connection between the fixed cylinder 5 and the rotating cylinder 3, the rotating cylinder 3 can be rotated when the fixed cylinder 5 is fixed, so as to respectively realize the fixation of the outer ring of the bearing and the rotation detection of the inner ring of the bearing, so an ejection rod 6 is slidably provided on the fixed cylinder 5, and the ejection rod 6 A fixed outer ring 1 is fixed to the end of the cylinder 3. The ejection rod 6 can push the fixed outer ring 1 to move under the action of power, clamping the fixed outer ring 1 to the outside of the outer ring of the bearing to fix the outer ring of the bearing. A clamping sleeve 14 is slidingly provided on the rotating cylinder 3. A fixed inner ring 2 is provided at the end of the clamping sleeve 14. The clamping sleeve 14 can move the fixed inner ring 2 outward through the power component inside the rotating cylinder 3 to fix the inner ring of the bearing. A power mechanism is provided inside the fixed cylinder 5 and the rotating cylinder 3, wherein the power mechanism drives the ejection rod 6 and the clamping sleeve 14 to move to achieve the clamping effect. In this application, in order to detect the quality of the bearing, a relevant sensor is provided inside the fixed inner ring 2, and the output end of the sensor is connected to the industrial Internet for real-time display and to determine whether it is a standard bearing.

[0037] The end of the clamping sleeve 14 is fixed with an articulated seat 15, wherein the articulated seat 15 is "U"-shaped, and a connecting rod 13 is hingedly and rotatably arranged on the articulated seat 15, wherein the end of the connecting rod 13 is rotatably arranged on an articulated shaft 17, and the articulated shaft 17 is fixedly mounted on a rotating disk 16. When the articulated shaft 17 is arranged on the rotating disk 16, there are multiple groups, so the clamping sleeve 14 is also provided with multiple groups, which can clamp the inner ring of the bearing and relatively fix it. The rotating disk 16 is driven by a clamping motor 9, wherein the power mechanism includes the clamping motor 9.

[0038] The clamping motor 9 drives the clamping shaft 8, and since a rotating disk 16 is fixed to the end of the clamping shaft 8, it can also drive the rotating disk 16 to rotate. Since the hinge shaft 17 is not on the straight extension line of the clamping sleeve 14 at this time, the connecting rod 13 rotates around the hinge shaft 17 at this time. At this time, the connecting rod 13 is skewed, so under the action of the connecting rod 13, the clamping sleeve 14 will be pulled to move, thereby realizing the adjustment of the position of the clamping sleeve 14, and can clamp and detect the inner rings of bearings of various sizes.

[0039] The clamping motor 9 is fixed at the output end of the test mechanism, the test mechanism is fixed inside the fixed cylinder 5, and the clamping motor 9 is connected to the power end of the ejection rod 6 through a transmission component. The test mechanism includes a test power box 12 and a motor mounting platform 10, and the motor mounting platform 10 is installed at the end of the test shaft 11, wherein the test shaft 11 is connected to the output end of the test power box 12, and the test power box 12 is used to provide power to the test shaft 11, wherein the test power box 12 includes various transmission components and corresponding drive motors, etc., and the test power box 12 is installed inside the fixed cylinder 5, which can ensure that the test power box 12 is fixed, and the upper fixed inner ring 2 and the rotating cylinder 3 can both rotate.

[0040] The test power box 12 is used to provide rotational power to drive the test shaft 11 to rotate. At this time, the motor mounting platform 10, the clamping motor 9, the clamping shaft 8 and the fixed inner ring 2 are integrated, which can drive the above-mentioned integrated body to rotate. At this time, the fixed inner ring 2 clamps the inner ring of the bearing, thereby driving the fixed inner ring 2 to rotate, realizing the bearing inner ring rotation test.

[0041] The ejection rod 6 is slidably connected to the fixed cylinder 5, so there are multiple groups of ejection rods 6. In this embodiment, the ejection rods 6 are symmetrically arranged to realize the clamping of the fixed outer ring 1 to the bearing outer ring, wherein the corresponding ejection rods 6 are arranged at the output end of the power component, wherein the output end of the power component includes a bidirectional screw assembly 30, wherein the ejection rod 6 is arranged on a fixed fixing seat 29, and the fixing seat 29 is arranged on the bidirectional screw assembly 30, and the bidirectional screw assembly 30 is used to drive the fixing seat 29 to move toward or away from each other, so as to realize the use of the ejection rod 6 to drive the fixed outer ring 1 to move toward or away from each other, and realize the clamping of the bearing outer ring, so in this application, the bidirectional screw assembly 30 includes a bidirectional screw and a limit rod, and the bidirectional screw assembly 30 is the prior art, and the rotation of the bidirectional screw in the bidirectional screw assembly 30 is used to realize the movement of the fixed seat 29 symmetrically arranged on the bidirectional screw toward or away from each other, wherein the fixed seat 29 and the limit rod are slidably connected to ensure that the fixed seat 29 moves horizontally instead of rotating.

[0042] By utilizing the action of the bidirectional screw assembly 30, the fixed seat 29 is driven to move laterally toward each other, so that the ejection rod 6 can move toward or away from each other under the action of the bidirectional screw assembly 30, thereby driving the fixed outer ring 1 to move toward or away from each other. When moving toward each other, the outer ring of the bearing can be clamped and fixed, and when moving away from each other, the outer ring of the bearing can be loosened to achieve blanking.

[0043] The power end of the bidirectional screw assembly 30 is fixed with an end gear 2 32, wherein the end of the end gear 2 32 away from the bidirectional screw assembly 30 is rotatably mounted inside the fixed cylinder 5, wherein the side of the end gear 2 32 is meshed with the end gear 1 33, and the end gear 1 33 is fixed on the driving shaft 31, and the driving shaft 31 is rotatably mounted inside the fixed cylinder 5, and a bevel gear 2 28 is fixed on the driving shaft 31, and the bevel gear 2 28 and the bevel gear 1 27 are meshed and connected, wherein the bevel gear 1 27 is fixed on the transmission shaft 26, and the transmission shaft 26 is fixed to the bottom of the test power box 12, wherein the transmission shaft 26 is connected to the clamping motor 9 through the transmission assembly, and the transmission assembly can control whether the clamping motor 9 drives the transmission shaft 26, that is, it can drive the transmission shaft 26, and can also disconnect the power end from the transmission shaft 26.

[0044] When the fixed inner ring 2 clamps the inner ring of the bearing, the clamping motor 9 is in action, and the transmission assembly is used to transmit the power end of the clamping motor 9 to the transmission shaft 26, and the transmission shaft 26 drives the bevel gear 1 27, so that the bevel gear 2 28 meshing with the bevel gear 1 27 rotates, driving the driving shaft 31, thereby providing power to the bidirectional screw assembly 30 under the action of the end gear 1 33 and the end gear 2 32. If the fixed outer ring 1 directly clamps the outer ring of the bearing, the power end is disconnected by the action of the transmission assembly, that is, the clamping motor 9 continues to act, and it is only clamping the fixed inner ring 2. In this process, pressure sensors are provided on the fixed outer ring 1 and the fixed inner ring 2 to detect the degree of clamping of the bearing. The above structure can ensure that the inner and outer rings of the bearing are clamped at the same time, avoiding delays during clamping and fixing, and ensuring work efficiency.

[0045] The transmission assembly includes a transmission wheel 20, wherein the transmission wheel 20 is fixed on the clamping shaft 8, and a connecting shaft 18 is rotatably provided on the top cover of the rotating cylinder 3, wherein a transmission wheel 22 is fixed on the connecting shaft 18, and the transmission wheel 20 and the transmission wheel 22 are rotated by a transmission belt 19, wherein the end of the connecting shaft 18 is connected to the transmission wheel 3 24 through an extended clamping component, wherein the extended clamping component includes a connecting telescopic rod 23, and a placement groove for placing the connecting telescopic rod 23 is opened at the end of the connecting shaft 18, which can be When the telescopic rod 23 is extended, the positions of the telescopic rod 23 and the connecting shaft 18 are relatively fixed. Therefore, in order to enable the extension of the telescopic rod 23 to enter the connecting shaft 18, a connecting through-hole 21 is provided on the test power box 12 and the motor mounting platform 10. The telescopic rod 23 is fixed on the transmission wheel three 24, and the transmission wheel four 25 is fixed on the transmission shaft 26, wherein the transmission wheel four 25 and the transmission wheel three 24 are driven and connected by the transmission belt two 34, and the transmission wheel three 24 is rotatably connected to the bottom of the fixed cylinder 5.

[0046] The connecting telescopic rod 23 is extended and enters the placement groove of the connecting shaft 18 to achieve relative fixation of the positions of the connecting shaft 18 and the connecting telescopic rod 23. The clamping motor 9 drives the clamping shaft 8, drives the transmission wheel 1 20, and drives the transmission wheel 2 22 under the action of the transmission belt 19, so that the connecting shaft 18 rotates, drives the transmission wheel 3 24 to rotate, and drives the transmission shaft 26 to rotate under the action of the transmission belt 2 34, thereby driving the bidirectional screw assembly 30. After the clamping of the bearing outer ring is completed, the connecting telescopic rod 23 is shortened, and the end of the connecting telescopic rod 23 is moved out of the placement groove to achieve separation of the bearing outer ring and the bearing inner ring.

[0047] Among them, the size of transmission wheel 1 20 is larger than that of transmission wheel 2 22, the size of transmission wheel 3 24 is larger than that of transmission wheel 4 25, the number of teeth of bevel gear 1 27 is larger than that of bevel gear 2 28, and the number of teeth of end gear 1 33 is larger than that of end gear 2 32. Under the above circumstances, the rotation angle of the clamping motor 9 can be converted into a drive with a larger rotation range, so that the outer ring of the bearing can be clamped and fixed first, and it can adapt to bearing outer rings and bearing inner rings of different thicknesses.

[0048] An outer ring limiting plate 7 is fixed on the fixed outer ring 1 to limit the position of the bearing outer ring to prevent the bearing from falling directly.

[0049] In the above process, since relevant sensors are arranged inside the fixed inner ring 2, and the output end of the sensor is connected to the industrial Internet for real-time display and judgment of whether it is a standard bearing, the sensors include an electronic stethoscope, a bearing vibration meter and a temperature sensor. The sound frequency detected by the electrical stethoscope is transmitted to the industrial Internet, and the sound emitted by the bearing is detected by the industrial Internet. If the sound frequency is stable and the operation is smooth and light, it is a normal bearing. If the bearing makes heavy or irregular noise when rotating, there is a problem with the bearing. After capturing the problem bearing, the industrial Internet transmits the information to the robot in the next step, and the defective products are directly removed and reworked. The bearing vibration meter detects the quality of the bearing by the size of the vibration and sends it to the robot in the next step for processing, while the temperature sensor detects whether a large amount of temperature is generated due to friction when the inner ring of the bearing rotates to judge the quality of the bearing.

[0050] When the present invention is in use, the bearing is first placed on the fixed outer ring 1 and the fixed inner ring 2, and then the clamping motor 9 is used to drive the clamping shaft 8 first. Since the end of the clamping shaft 8 is fixed with a rotating disk 16, the rotating disk 16 can also be driven to rotate. Since the hinge shaft 17 is not on the straight extension line of the clamping sleeve 14 at this time, the connecting rod 13 rotates around the hinge shaft 17. At this time, the connecting rod 13 is deflected, so the clamping sleeve 14 is pulled to move under the action of the connecting rod 13, so the position of the clamping sleeve 14 can be adjusted, and various sizes of bearings can be adjusted. The inner ring of the bearing is clamped and tested; at the same time, when the connecting telescopic rod 23 is extended to enter the placement groove of the connecting shaft 18, the clamping motor 9 is used to drive the clamping shaft 8, drive the transmission wheel 1 20, and drive the transmission wheel 2 22 under the action of the transmission belt 19, so that the connecting shaft 18 rotates, drives the transmission wheel 3 24 to rotate, and drives the transmission shaft 26 to rotate under the action of the transmission belt 2 34, thereby driving the bidirectional screw assembly 30. After the outer ring of the bearing is clamped, the connecting telescopic rod 23 is shortened, and the end of the connecting telescopic rod 23 is moved out of the placement groove;

[0051] During this process, the test power box 12 is used to provide rotational power to drive the test shaft 11 to rotate. At this time, the fixed inner ring 2 clamps the inner ring of the bearing, thereby driving the fixed inner ring 2 to rotate, realizing the bearing inner ring rotation test, that is, a relevant sensor is arranged inside the fixed inner ring 2, and the output end of the sensor is connected to the industrial Internet for real-time display and judgment whether it is a standard bearing. The sensors include an electronic stethoscope, a bearing vibration meter and a temperature sensor to detect whether there is any abnormality in the bearing during rotation.

[0052] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments using the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
