[0002] Bearings are an important component of modern mechanical equipment. They can be divided into two categories according to their friction properties: sliding bearings and rolling bearings. Rolling bearings are generally composed of an inner ring, an outer ring, balls and a cage. In order to have good rotation performance and a long service life, rolling bearings generally have grease injected between the inner and outer rings to achieve good lubrication and then install the sealing end cover.

[0003] At present, the method of injecting lubricating oil into bearings is usually to fix the bearings by hand or machine, and then inject oil into the bearings. However, since the bearing grooves on the production line cannot be accurately aligned with the oil injection structure, the grease cannot be accurately injected into the bearing grooves, increasing the risk of grease leakage. In addition, the grease injection of each ball of the bearing is uneven, which can easily cause eccentric wear of the bearing and reduce the service life of the bearing. For this reason, we provide an automated injection line for bearing grease injection. Summary of the invention

[0004] The purpose of the present invention is to make up for the deficiencies of the prior art and to provide an automated injection line for bearing grease filling. This solution can realize the automated grease filling operation of the bearing, reduce the workload of the operator and make the bearing grease filling operation more precise, thereby making the bearing production process more efficient. The two-sided step-by-step grease filling method is adopted and detection is performed before and after the grease filling, thereby making the bearing grease filling more precise. At the same time, the bearing is turned over after the grease filling, so that the grease is more evenly distributed in the bearing, thereby avoiding eccentric wear of the bearing and thereby increasing the service life of the bearing. The bearing after the grease filling is then subjected to double-sided flexibility detection to ensure that the produced bearings meet the required quality requirements.

DETAILED DESCRIPTION

[0032] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0033] It should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrally formed structure. For ordinary technicians in this field, the specific meanings of such terms in this patent can be understood according to specific circumstances.

[0034] As described in the background technology, since the bearing grooves on the production line cannot ensure precise alignment with the oil injection structure, the grease cannot be accurately injected into the bearing grooves, increasing the risk of grease leakage. In addition, the grease injection of the bearing balls is uneven, which can easily cause eccentric wear of the bearings and reduce the service life of the bearings. For this reason, the present embodiment provides an automated injection line for bearing grease injection. The device can realize automated grease injection operations on bearings, reduce the workload of operators, and make the bearing oil injection operations more precise, thereby making the bearing production process more efficient. The two-sided step-by-step oil injection method is adopted, and detection is performed before and after the oil injection, thereby making the bearing oil injection more precise. At the same time, the bearing is rotated after oil injection, so that the grease is more evenly distributed in the bearing, thereby avoiding eccentric wear of the bearing and thus increasing the service life of the bearing. Thereafter, the bearing after oil injection is tested for flexibility to ensure that the produced bearings meet the required quality requirements.

[0035] See also Figure 1 - Figure 6The present embodiment proposes an automated injection line for bearing grease injection, including a bearing grease injection production line 1. The outside of the bearing grease injection production line 1 is provided with a conveying component for driving the bearing to move horizontally along the upper surface of the bearing grease injection production line 1, a conveying detection component for controlling the start and stop of the bearing conveying component, a weighing component for weighing the bearing weight, a rejection component for removing unqualified bearings, an oiling component for grease injection for bearings to achieve good lubrication, a flipping component for turning over the bearing, and a flexibility detection component for bearing flexibility detection.

[0036] The conveying assembly includes a first cylinder 201 installed on the upper surface of the bearing oiling production line 1, the telescopic end of the first cylinder 201 is fixedly connected to a slider 202 which is slidably connected to the bearing oiling production line 1, a second cylinder 203 is installed on the upper surface of the slider 202, and the telescopic end of the second cylinder 203 is fixedly connected to a conveying plate 204 which is slidably connected to the bearing oiling production line 1.

[0037] The first cylinder 201 is powered on and started, and its output end is extended and retracted, which can drive the slider 202 to move left and right in the horizontal direction along the bearing oiling production line 1. Then, the second cylinder 203 is powered on and started, and its output end is extended and retracted, which can drive the conveying plate 204 to move back and forth in the horizontal direction along the bearing oiling production line 1. The reserved groove on the conveying plate 204 can be used to drive the bearing to be horizontally conveyed along the upper surface of the bearing oiling production line 1.

[0038] The reserved grooves are evenly distributed along the conveying direction of the bearing, and the distances between adjacent reserved grooves are equal and are set equal to the distances between adjacent workstations of each component. The conveying component is used to convey the bearing to the corresponding workstation for corresponding operation.

[0039] The conveying detection component includes a first support plate 301 fixedly connected to the bearing oiling production line 1, and a distance sensor 302 is installed on the inner wall of the first support plate 301. The weighing component includes a weighing cylinder 401 installed on the inner wall of the bearing oiling production line 1, and the telescopic end of the weighing cylinder 401 is fixedly connected to a weighing plate 402 that is slidably connected to the bearing oiling production line 1.

[0040] The distance sensor 302 installed on the inner wall of the first support plate 301 can detect whether there are bearings that need to be transported on the production line. The distance sensor 302 detects whether the distance between the upper surfaces of the bearing oiling production line 1 changes, thereby determining whether there are bearings to be transported, and transmits it to the controller in the form of an electrical signal, thereby controlling the conveying component to perform corresponding actions.

[0041] The weighing cylinder 401 is provided with a weighing sensor, which can weigh the bearing delivered to the upper weighing plate 402, so as to obtain the weight value of the bearing at this station and calculate the weight change of subsequent weighing, so as to improve the accuracy of bearing oiling.

[0042] The rejection assembly includes a third cylinder 501 installed on the inner wall of the bearing oiling production line 1, the telescopic end of the third cylinder 501 is fixedly connected to a first slide plate 502 which is slidably connected to the bearing oiling production line 1, and a discharge chute for removing unqualified bearings is arranged below the first slide plate 502.

[0043] The third cylinder 501 is connected to a power source and started, and its telescopic end is extended and retracted, which can drive the first slide plate 502 to slide back and forth in the inner wall of the bearing oiling production line 1, so as to remove the unqualified bearings on the first slide plate 502, so that the unqualified bearings can fall into the collection frame placed under the bearing oiling production line 1 through the discharge chute for centralized processing. After the unqualified bearings are removed, the first slide plate 502 can be driven by the third cylinder 501 to move to the initial position.

[0044] The oiling assembly includes a second support plate 601 fixedly connected to the bearing oiling production line 1, a fourth cylinder 602 is installed on the inner wall of the second support plate 601, the telescopic end of the fourth cylinder 602 is fixedly connected to the second slide plate 603 which is slidably connected to the second support plate 601, an oiler 604 is inlaid on the inner wall of the second slide plate 603, the bottom end of the oiler 604 is connected to an oiling head 605, and the bottom surface of the oiling head 605 is provided with a plurality of oiling nozzles 606 arranged in a circle.

[0045] The fourth cylinder 602 is connected to a power source and started, and its telescopic end is extended and retracted, which can drive the second slide plate 603 to slide up and down along the inner wall of the second support plate 601, and then drive the oiling head 605 to move up and down through the oiler 604, and the oiling head 605 drives the oiling nozzle 606 to move up and down, so as to perform oiling operation on the bearing. The oiling nozzle 606 adopts a design of gradually reducing the aperture from top to bottom, which can make it easier for the oiling nozzle 606 to align with the gap between the inner ring and the outer ring of the bearing, and the circumferentially arranged oiling nozzles 606 can make the oiling operation more uniform. At the same time, the number and position of the oiling nozzles 606 are set corresponding to the balls on the bearing.

[0046] The oiling assembly also includes a monitoring sensor 607 and a telescopic rod 608 fixed to the oiling head 605, and a first servo motor 6011 installed on the inner wall of the bearing oiling production line 1, the bottom end of the telescopic rod 608 is fixedly connected to a limiting ring 609, a buffer spring 6010 is arranged inside the telescopic rod 608, the output shaft end of the first servo motor 6011 is fixedly connected to a fifth cylinder 6012, the telescopic end of the fifth cylinder 6012 is fixedly connected to a fixed frame 6013, the inner wall of the fixed frame 6013 is installed with a sixth cylinder 6014, and the telescopic end of the sixth cylinder 6014 is fixedly connected to a limiting block 6015.

[0047] After the bearing is transported to the bottom of the oiling head 605, the fifth cylinder 6012 can be connected to the power supply and started, and its telescopic end can be extended and retracted to drive the limit block 6015 to move up to the inner ring of the bearing. Then the sixth cylinder 6014 is connected to the power supply and started, and its telescopic end can be extended and retracted to drive the limit block 6015 to fit with the inner ring of the bearing, thereby fixing the bearing. Then the oiling head 605 is controlled to move downward, so that the limit ring 609 first fits with the outer ring of the bearing, and when the oiling head 605 continues to move downward, the buffer spring 6010 is compressed to produce elastic deformation, and the reset effect of the buffer spring 6010 can make the limit ring 609 tend to move downward, thereby fixing the outer ring of the bearing.

[0048] At the same time, the bearing groove is detected by monitoring sensor 607. When it is detected that it is not aligned with the oiling nozzle 606, the first servo motor 6011 can be controlled to connect the power supply and start, and the inner ring of the bearing can be driven to rotate through the limit block 6015, so that the bearing groove and the oiling nozzle 606 are accurately aligned, thereby achieving accurate oiling of the bearing and reducing the risk of grease leakage. Then, after the oiling, the oiling nozzle 606 is moved up, and the inner ring of the bearing is driven to rotate through the limit block 6015 to mix the grease evenly. After the oiling is completed, the limit on the bearing can be released for subsequent transportation.

[0049] The flip assembly includes a second servo motor 701 installed on the inner wall of the bearing oiling production line 1 , the output shaft end of the second servo motor 701 is fixedly connected with a flip block 702 , and the flip block 702 is rotatably connected to the bearing oiling production line 1 .

[0050] The groove surface on the flip block 702 is flush with the upper surface of the bearing oiling production line 1. When the second servo motor 701 is powered on and started, it can drive the flip block 702 to rotate 180 degrees along the inner wall of the bearing oiling production line 1, thereby flipping the bearing so that the bearing can be double-sidedly oiled and flexibility tested, thereby ensuring that the produced bearings meet the required quality requirements.

[0051] The flexibility detection component includes a third support plate 801 fixedly connected to the bearing oiling production line 1 and a bearing seat 807 fixed to the inner wall of the bearing oiling production line 1 by bolts, the inner wall of the third support plate 801 is installed with a seventh cylinder 802, the telescopic end of the seventh cylinder 802 is fixedly connected to a third slide plate 803 slidably connected to the third support plate 801, the upper surface of the third slide plate 803 is installed with a third servo motor 804, the output shaft end of the third servo motor 804 is fixedly connected to a rotating sleeve 805, and the bottom of the rotating sleeve 805 is connected to a gear plate 806.

[0052] The specific setting method of the flexibility detection component can refer to the existing patent CN210802900U6, which will not be repeated here. The upper surface of the bearing seat 807 is provided with a countersunk hole, which allows the inner ring of the bearing to be tested to rotate freely.

[0053] After the bearing is transported to the bearing seat 807, the seventh cylinder 802 can be connected to the power supply and started, and its telescopic end can be extended and retracted, which can drive the third slide plate 803 to slide up and down along the inner wall of the third support plate 801, and then drive the gear plate 806 to move up and down. When the gear plate 806 moves down and contacts the inner hole of the bearing, the third servo motor 804 can be connected to the power supply and started, so as to drive the gear plate 806 to rotate through the rotating sleeve 805, and then drive the inner ring of the bearing to rotate. Then the third servo motor 804 is stopped, and affected by the friction torque of the bearing, the gear plate 806 maintains the rotation inertia for a certain period of time, and then the rotation speed slows down and finally stops rotating, thereby realizing the detection of the flexibility of the bearing, that is, the flexibility of the bearing is detected by the number of circles that the gear plate 806 rotates in the inner hole of the bearing by inertia.

[0054] The automated bearing oiling production line 1 achieves precise oiling, flipping and flexibility testing of bearings through a series of components working together. The specific process is as follows:

[0055] Conveying and Detection Conveying components, conveying detection components:

[0056] The bearing is placed on the conveying plate 204 , and the conveying assembly driven by the first cylinder 201 and the second cylinder 203 moves the bearing horizontally along the bearing oiling production line 1 .

[0057] The distance sensor 302 detects whether the bearing reaches the specified position to ensure the accuracy of subsequent operations.

[0058] Weighing and Rejection Weighing components, rejecting components:

[0059] The weighing assembly composed of the weighing cylinder 401 and the weighing plate 402 weighs the weight of the bearing.

[0060] If the weight of the bearing does not meet the standard, the first slide plate 502 driven by the third cylinder 501 removes the unqualified bearing to the discharge chute.

[0061] Oiling and aligning oiling kit:

[0062] After the bearing reaches the oiling position, the oiling head 605 and the oiling nozzle 606 driven by the fourth cylinder 602 descend to prepare for oiling.

[0063] The monitoring sensor 607 detects the alignment of the bearing channel and the grease nozzle 606.

[0064] If adjustment is required, the first servo motor 6011 drives the inner ring of the bearing to rotate through the limit block 6015 to achieve precise alignment.

[0065] After the oiling is completed, the oiling head 605 rises, and the inner ring of the bearing continues to rotate to make the grease evenly distributed.

[0066] Flip and double-sided oiling flip assembly:

[0067] The flip block 702 driven by the second servo motor 701 flips the bearing 180 degrees to allow for second-side oiling.

[0068] Flexibility TestFlexibility Test Components:

[0069] The bearing is transported to the bearing seat 807, and the gear plate 806 driven by the seventh cylinder 802 contacts the inner hole of the bearing.

[0070] The third servo motor 804 is started, and drives the gear plate 806 to rotate through the rotating sleeve 805, thereby driving the inner ring of the bearing to rotate.

[0071] After the third servo motor 804 is stopped, the flexibility of the bearing is detected according to the number of revolutions of the gear plate 806 in the inner hole of the bearing due to inertia.
