Description

Technical Field

[0001] This invention relates to the field of slewing bearing processing equipment, and in particular to an integrated equipment and processing method for slewing bearing oil injection and sealing strip installation. Background Technology

[0002] Slewing bearings are widely used in construction machinery such as excavators, cranes, hoists, and forestry machinery.

[0003] like Figure 1 As shown, a slewing bearing typically includes an outer support ring 100 and an inner support ring 200 mounted within the outer support ring 100. A ball bearing channel is provided between the outer support ring 100 and the inner support ring 200, and balls are installed within the ball bearing channel. To reduce the frictional force on the balls during operation, a suitable amount of lubricating oil is usually injected into the slewing bearing. The outer support ring 100 of the slewing bearing has an oil injection hole 101. During oil injection, the oil injection pipe is inserted into the oil injection hole 101 of the slewing bearing, and then the inner support ring 200 is rotated. The ball bearing channel and the balls within the slewing bearing will then be fully covered by lubricating oil. Figure 1 As shown, a sealing strip 400 and an annular sealing strip mounting groove 300 are respectively provided on both sides of the slewing bearing. The annular sealing strip mounting groove 300 is located on both sides of the connection between the outer ring 100 and the inner ring 200 of the bearing. The sealing strip 400 is installed inside the annular sealing strip mounting groove 300. The sealing strip 400 can prevent the lubricating oil inside the slewing bearing from leaking out.

[0004] In existing technologies, the lubrication process for slewing bearings typically requires the use of lubrication equipment. This equipment includes a slewing bearing support device and a bearing inner ring rotation device. When using the equipment, the slewing bearing is placed on the support device, and the lubrication pipe is inserted into the lubrication hole 101. The bearing inner ring 200 is then rotated by the inner ring rotation device to complete the lubrication. However, current lubrication equipment lacks the function of installing the sealing strip 400 on the slewing bearing. Before lubrication, workers must manually apply adhesive to the sealing strip and press it into the annular sealing strip mounting groove 300 of the slewing bearing. This manual sealing strip installation method is inefficient, lacks quality assurance, and has high labor costs. Furthermore, the sealing strip installation and lubrication processes cannot be completed simultaneously, further reducing processing efficiency. Summary of the Invention

This device, in conjunction with a turntable system, a support and centering system, and a sealing strip installation system, can install sealing strips into the annular sealing strip mounting groove of the slewing bearing. This method offers high efficiency, guaranteed quality, and low labor costs. Furthermore, the device can inject lubricating oil into the slewing bearing in conjunction with the support and centering system and the oil injection system, allowing the oil injection and sealing strip installation processes to be completed on the same machine.

[0015] To solve the second technical problem mentioned above, the technical solution of the present invention is: a processing method for the integrated equipment for oil injection and sealing strip installation of the slewing bearing, comprising the following steps: S1. Loosen the centering clamping unit, place the slewing bearing to be processed on the support unit, and support the outer ring of the slewing bearing through the support unit; then tighten the centering clamping unit so that the centering clamping unit clamps the outer ring of the slewing bearing and keeps the center of the slewing bearing and the rotation axis of the turntable in the same position. S2. Install the sealing strip in the annular sealing strip mounting groove on one side of the slewing bearing: (1) The robotic arm moves the sealing strip guide device, the sealing strip glue applicator and the sealing strip pressing device to the set position; (2) After the sealing strip passes through the sealing strip guide device, it reaches the position of the annular sealing strip mounting groove on one side of the slewing bearing. The sealing strip glue applicator applies glue to the sealing strip that has passed through the sealing strip guide device; (3) The sealing strip pressing device presses the sealing strip after applying glue into the annular sealing strip mounting groove on one side of the slewing bearing; At the same time as steps (2) and (3), the turntable drive device drives the turntable to rotate, and the turntable drives the slewing bearing to rotate. After the slewing bearing rotates once, the sealing strip is pressed into the annular sealing strip mounting groove on the entire side of the slewing bearing. At this time, the turntable drive device stops working, and the worker cuts off the tail end of the sealing strip and glues the head and tail ends of the sealing strip together in the annular sealing strip mounting groove on one side of the slewing bearing. S3. The robotic arm drives the sealing strip guide device, sealing strip glue applicator and sealing strip pressing device to reset, so that the sealing strip installation system is separated from the slewing bearing. Then, the centering clamping unit is released, and the slewing bearing is flipped so that the other side of the slewing bearing faces upward. Then, the centering clamping unit is tightened so that the centering clamping unit clamps the outer ring of the slewing bearing and keeps the center of the slewing bearing and the rotation axis of the turntable in the same position. S4. Install the sealing strip in the annular sealing strip mounting groove on the other side of the slewing bearing: (1) The robotic arm moves the sealing strip guide device, the sealing strip glue applicator and the sealing strip pressing device to the set position; (2) After the sealing strip passes through the sealing strip guide device, it reaches the position of the annular sealing strip mounting groove on the other side of the slewing bearing. The sealing strip glue applicator applies glue to the sealing strip that has passed through the sealing strip guide device; (3) The sealing strip pressing device presses the sealing strip after applying glue into the annular sealing strip mounting groove on the other side of the slewing bearing; At the same time as steps (2) and (3), the turntable drive device drives the turntable to rotate, and the turntable drives the slewing bearing to rotate. After the slewing bearing rotates one revolution, the sealing strip is pressed into the annular sealing strip mounting groove on the other side of the slewing bearing. At this time, the turntable drive device stops working, and the worker cuts off the tail end of the sealing strip and glues the head and tail ends of the sealing strip together in the annular sealing strip mounting groove on the other side of the slewing bearing. S5. The robotic arm drives the sealing strip guide device, sealing strip glue applicator and sealing strip pressing device to reset, so that the sealing strip installation system is separated from the slewing bearing. Then, the oil injection pipe of the oil injection system is inserted into the oil injection hole of the outer ring of the slewing bearing and lubricating oil is injected into the slewing bearing through the oil injection pipe. At the same time, the first inner ring drive device of the oil injection system drives the inner ring of the slewing bearing to rotate until the oil injection is completed. S6. After the oil injection is completed, pull the oil injection pipe of the oil injection system out of the oil injection hole of the outer ring of the slewing bearing, plug the oil injection hole of the outer ring of the slewing bearing with the plug, then control the first inner ring drive device to stop working and separate from the inner ring of the slewing bearing, and finally release the centering clamping unit and take out the slewing bearing.

[0016] The beneficial effects of the present invention are: (1) The support and centering system of the present invention is installed on the turntable. The support unit can support the outer ring of the slewing bearing, and the centering clamping unit clamps the outer ring of the slewing bearing and keeps the center of the slewing bearing and the rotation axis of the turntable in the same position. This structure can not only position the slewing bearing, but also ensure that the slewing bearing and the turntable can rotate concentrically when the turntable rotates. This provides the prerequisite for the sealing strip installation system to install the sealing strip on the annular sealing strip mounting groove of the slewing bearing; the robotic arm of the present invention can transmit the sealing strip guiding device, the sealing strip gluing device and the sealing strip pressing device to the working position. While the turntable drives the slewing bearing to rotate, the sealing strip guiding device can guide the sealing strip to the annular sealing strip mounting groove of the slewing bearing, the sealing strip gluing device can apply glue to the sealing strip, and the sealing strip pressing device can press the sealing strip after applying glue into the slewing bearing. Within the annular sealing strip mounting groove, after the turntable drives the slewing bearing to rotate one revolution (360 degrees), the sealing strip can be pressed into the annular sealing strip mounting groove on the entire side of the slewing bearing; it can be seen that the present invention can install the sealing strip into the annular sealing strip mounting groove of the slewing bearing with the cooperation of the turntable system, the support and centering system and the sealing strip mounting system. The sealing strip installation efficiency is high, the quality can be guaranteed, and the labor cost is low; (2) After the support and centering system of the present invention supports and positions the outer ring of the slewing bearing, it can drive the inner ring of the slewing bearing through the first inner ring drive device of the oil injection system. At the same time, the oil injection pipe is inserted into the oil injection hole of the outer ring of the slewing bearing and lubricating oil is injected into the slewing bearing. It can be seen that the present invention can inject lubricating oil into the slewing bearing with the cooperation of the support and centering system and the oil injection system. The oil injection process and the sealing strip mounting process can be completed on the same machine, further improving the processing efficiency. Attached Figure Description

[0026] The structural and working principles of the present invention will be further described in detail below with reference to the accompanying drawings.

[0027] like Figure 1 The diagram shows the structure of the slewing bearing and sealing strip to be processed according to the present invention. The slewing bearing includes an outer support ring 100 and an inner support ring 200 installed inside the outer support ring 100. A ball bearing channel is provided between the outer support ring 100 and the inner support ring 200, and balls are installed inside the ball bearing channel. The outer support ring 100 of the slewing bearing is provided with an oil injection hole 101. A sealing strip 400 and an annular sealing strip mounting groove 300 are respectively provided on both sides of the slewing bearing. The annular sealing strip mounting groove 300 is located on both sides of the connection between the outer support ring 100 and the inner support ring 200. The sealing strip 400 is installed inside the annular sealing strip mounting groove 300. The sealing strip 400 can prevent the lubricating oil inside the slewing bearing from leaking out.

[0028] like Figures 2-9As shown, the present invention provides an integrated device for slewing bearing oil injection and sealing strip installation, including a turntable system 1, a support and centering system 2, an oil injection system 3, and a sealing strip installation system 4; the turntable system 1 includes a turntable 11 and a turntable drive device 12, the turntable drive device 12 being used to drive the turntable 11 to rotate; the support and centering system 2 is mounted on the turntable 11, the support and centering system 2 including a support unit 21 and a centering clamping unit 22, the support unit 21 being used to support the outer ring 100 of the slewing bearing, the centering clamping unit 22 being used to clamp the outer ring 100 of the slewing bearing and keep the center of the slewing bearing and the rotation axis of the turntable 11 in the same position; the oil injection system 3 includes an oil injection pipe 31 and a first inner ring drive Device 32, the oil injection pipe 31 is used to connect to the oil injection hole of the outer ring 100 of the slewing bearing, the first inner ring drive device 32 is installed on the turntable 11, and the first inner ring drive device 32 is used to drive the inner ring 200 of the slewing bearing to rotate; the sealing strip installation system 4 includes a robotic arm 41 and a sealing strip guide device 42, a sealing strip glue application device 43 and a sealing strip pressing device 44 installed on the robotic arm 41, the sealing strip guide device 42 is used to guide the sealing strip to the annular sealing strip mounting groove 400 of the slewing bearing, the sealing strip glue application device 43 is used to apply glue to the sealing strip, and the sealing strip pressing device 44 is used to press the sealed strip after applying glue into the annular sealing strip mounting groove 400 of the slewing bearing.

[0029] The processing method of the integrated equipment for oil injection and sealing strip installation of slewing bearings according to the present invention includes the following steps: S1. Loosen the centering clamping unit 22, place the slewing bearing to be processed on the support unit 21, and support the outer ring 100 of the slewing bearing through the support unit 21; then tighten the centering clamping unit 22 so that the centering clamping unit 22 clamps the outer ring 100 of the slewing bearing and keeps the center of the slewing bearing in the same position as the rotation axis of the turntable 11. S2. Install the sealing strip in the annular sealing strip mounting groove 400 on one side of the slewing bearing: (1) The robotic arm 41 moves the sealing strip guide device 42, the sealing strip glue applicator 43, and the sealing strip pressing device 44 to the set position; (2) After passing through the sealing strip guide device 42, the sealing strip reaches the position of the annular sealing strip mounting groove 400 on one side of the slewing bearing. Note: The sealing strip is a long strip structure when it is introduced. The sealing strip glue applicator 43 applies glue to the sealing strip that has passed through the sealing strip guide device 42; (3) The sealing strip pressing device 44 applies glue. The sealing strip is then pressed into the annular sealing strip mounting groove 400 on one side of the slewing bearing; at the same time as steps (2) and (3), the turntable drive device 12 drives the turntable 11 to rotate, and the turntable 11 then drives the slewing bearing to rotate. After the slewing bearing rotates once, the sealing strip is pressed into the annular sealing strip mounting groove 400 on the entire side of the slewing bearing. At this time, the turntable drive device 12 stops working, and the workers cut off the tail end of the sealing strip and bond the head and tail ends of the sealing strip together and fix them in the annular sealing strip mounting groove 400 on one side of the slewing bearing. S3. The robotic arm 41 drives the sealing strip guide device 42, the sealing strip glue applicator 43, and the sealing strip pressing device 44 to reset, so that the sealing strip installation system 4 is separated from the slewing bearing. Then, the centering clamping unit 22 is released, and the slewing bearing is flipped so that the other side of the slewing bearing faces upward. Then, the centering clamping unit 22 is tightened so that the centering clamping unit 22 clamps the outer ring 100 of the slewing bearing and keeps the center of the slewing bearing in the same position as the rotation axis of the turntable 11. S4. Install the sealing strip in the annular sealing strip mounting groove 400 on the other side of the slewing bearing: (1) The robotic arm 41 moves the sealing strip guide device 42, the sealing strip glue applicator 43, and the sealing strip pressing device 44 to the set position; (2) After the sealing strip passes through the sealing strip guide device 42, it reaches the position of the annular sealing strip mounting groove 400 on the other side of the slewing bearing, and the sealing strip glue applicator 43 applies glue to the sealing strip that has passed through the sealing strip guide device 42; (3) The sealing strip pressing device 44 presses the sealing strip after applying glue into the annular sealing strip mounting groove 400 on the other side of the slewing bearing. Inside the annular sealing strip mounting groove 400 on the other side of the slewing bearing; while in steps (2) and (3), the turntable drive device 12 drives the turntable 11 to rotate, and the turntable 11 then drives the slewing bearing to rotate. After the slewing bearing rotates once, the sealing strip is pressed into the annular sealing strip mounting groove 400 on the other side of the slewing bearing. At this time, the turntable drive device 12 stops working, and the workers cut off the tail end of the sealing strip and bond the head and tail ends of the sealing strip together and fix them in the annular sealing strip mounting groove 400 on the other side of the slewing bearing. S5. The robotic arm 41 drives the sealing strip guide device 42, the sealing strip glue applicator 43, and the sealing strip pressing device 44 to reset, so that the sealing strip installation system 4 is separated from the slewing bearing. Then, the oil injection pipe 31 of the oil injection system 3 is inserted into the oil injection hole of the outer ring 100 of the slewing bearing and lubricating oil is introduced into the slewing bearing through the oil injection pipe 31. At the same time, the first inner ring drive device 32 of the oil injection system 3 drives the inner ring 200 of the slewing bearing to rotate until the oil injection is completed. S6. After the oil injection is completed, pull the oil injection pipe 31 of the oil injection system 3 out of the oil injection hole of the outer ring 100 of the slewing bearing, plug the oil injection hole of the outer ring 100 of the slewing bearing with a plug, then control the first inner ring drive device 32 to stop working and separate it from the inner ring 200 of the slewing bearing, and finally release the centering clamping unit 22 and take out the slewing bearing.

[0030] The support and centering system 2 of the present invention is mounted on the turntable 11. The support unit 21 supports the outer ring 100 of the slewing bearing, and the centering clamping unit 22 clamps the outer ring 100 of the slewing bearing, keeping the center of the slewing bearing and the rotation axis of the turntable 11 in the same position. This structure not only positions the slewing bearing but also ensures that the slewing bearing and the turntable 11 rotate concentrically when the turntable 11 rotates. This facilitates the installation of the sealing strip system 4 on the annular sealing strip of the slewing bearing. The installation of the sealing strip on the groove 400 provides the prerequisite; the robotic arm 41 of the present invention can convey the sealing strip guiding device 42, the sealing strip glue applicator 43, and the sealing strip pressing device 44 to the working position. While the turntable 11 drives the slewing bearing to rotate, the sealing strip guiding device 42 can guide the sealing strip to the annular sealing strip mounting groove 400 of the slewing bearing, the sealing strip glue applicator 43 can apply glue to the sealing strip, and the sealing strip pressing device 44 can press the glued sealing strip into the slewing bearing. Within the annular sealing strip mounting groove 400, after the turntable 11 drives the slewing bearing to rotate one revolution (360 degrees), the sealing strip can be pressed into the annular sealing strip mounting groove 400 on the entire side of the slewing bearing. Therefore, this invention can install the sealing strip into the annular sealing strip mounting groove 400 of the slewing bearing with the cooperation of the turntable 11 system 1, the support and centering system 2, and the sealing strip mounting system 4. This results in high sealing strip installation efficiency, guaranteed quality, and low labor costs. After supporting and positioning the outer ring 100 of the slewing bearing, the support and centering system 2 of this invention can drive the inner ring 200 of the slewing bearing through the first inner ring drive device 32 of the oil injection system 3. Simultaneously, lubricating oil is injected into the slewing bearing through the oil injection pipe 31 connected to the oil injection hole of the outer ring 100 of the slewing bearing. Therefore, this invention can inject lubricating oil into the slewing bearing with the cooperation of the support and centering system 2 and the oil injection system 3. The oil injection process and the sealing strip mounting process can be completed on the same machine, further improving processing efficiency.

[0031] like Figures 2-7 As shown, the integrated equipment for slewing bearing oil injection and sealing strip installation also includes a machine base 5. The turntable drive device 12 includes a machine base support 121 and a second inner ring drive device 122. The machine base support 121 includes a machine base support outer ring 1211 and a machine base support inner ring 1212 installed inside the machine base support outer ring 1211. The machine base support outer ring 1211 is installed on the machine base 5, and the turntable 11 is installed on the machine base support inner ring 1212. The second inner ring drive device 122 includes a second motor 1221 and a second gear 1222. The second motor 1221 is installed on the machine base 5, and the second gear 1222 is installed on the power output shaft of the second motor 1221. The inner side of the machine base support inner ring 1212 is provided with machine base support internal teeth. The second gear 1222 meshes with the machine base support internal teeth to drive the machine base support inner ring 1212 to rotate. The present invention drives the inner ring 1212 of the machine support 121 through the second inner ring drive device 122, and then drives the turntable 11 to rotate through the inner ring 1212 of the machine support 121. This makes the rotational stability of the turntable 11 very good, and it can rotate at a relatively slow speed, making start-up and stop control easy.

[0032] like Figures 2-7As shown, the support and centering system 2 has 3 to 5 support units 21, which are arranged circumferentially along the slewing bearing. Each support unit 21 includes a support roller 211 and a support roller positioning frame 212. The support roller positioning frame 212 is mounted on the turntable 11, and the support roller 211 is rotatably mounted on the support roller positioning frame 212. The rotation axis of the support roller 211 is aligned with the radial direction of the slewing bearing. The centering and clamping unit 22 includes a claw bar tensioning device 221 and a claw bar 222. The claw bar tensioning device 221 is mounted on the center of the turntable 11, and the length direction of the claw bar 222 is aligned with the radial direction of the slewing bearing. The inner end of the claw bar 222 is connected to the claw bar tensioning device 221. Next, a clamping block 2221 is installed on the outer end of the claw bar 222. The clamping block 2221 is used to clamp the outer side of the outer ring 100 of the slewing bearing. There are 3 claw bars 222, and the included angle between adjacent claw bars 222 is 120 degrees. The claw bar tensioning device 221 can drive the 3 claw bars 222 to move inward or outward along the radial direction of the slewing bearing. When the claw bar tensioning device 221 drives the 3 claw bars 222 to move inward, the clamping block 2221 of the 3 claw bars 222 can clamp the outer ring 100 of the slewing bearing together and keep the center of the slewing bearing in the same position as the rotation axis of the turntable 11. When the claw bar tensioning device 221 drives the 3 claw bars 222 to move outward, the 3 claw bars 222 can release the clamping of the slewing bearing. The present invention employs 3 to 5 support units 21 arranged along the circumference of the slewing bearing, which can support the slewing bearing from 3 to 5 positions to prevent the slewing bearing from deviating to the side. Due to the structure of the support rollers 211 of the support unit 21, the position of the slewing bearing can be adjusted by rotation on each support roller 211, and the position of the slewing bearing can also be adjusted along the length of the support rollers 211. This invention uses three claw bars 222 to clamp the slewing bearing. Since the included angle between adjacent claw bars 222 is 120 degrees, the line connecting the clamping blocks 2221 of the three claw bars 222 can form an equilateral triangle. One end of each of the three claw bars 222 is connected to the claw bar tensioning device 221. Therefore, under the action of the claw bar tensioning device 221, the clamping blocks 2221 of the three claw bars 222 can jointly clamp the outer ring 100 of the slewing bearing and keep the center of the slewing bearing and the rotation axis of the turntable 11 in the same position. In this way, when the turntable 11 rotates, the slewing bearing and the turntable 11 will always remain concentric, and finally the sealing strip installation system 4 can smoothly install the sealing strip into the annular sealing strip installation groove 400.

[0033] like Figures 4-7As shown, the claw lever tensioning device 221 includes a disc-shaped housing 2211, a disc-shaped drive disk 2212, a slider 2213, and a drive rod 2214. The disc-shaped housing 2211 is fixedly installed on the center of the turntable 11. The disc-shaped drive disk 2212 is rotatably installed inside the disc-shaped housing 2211. The rotation axis of the disc-shaped drive disk 2212 is kept at the same position as the rotation axis of the turntable 11. A spiral groove 2215 is provided on the upper side of the disc-shaped drive disk 2212. A toothed ring 2216 is provided at the lower edge of 212; there are 3 sliders 2213, which are respectively connected to the lower inner end of 3 claw rods 222. The lower side of the slider 2213 is provided with a number of sliding teeth 2217, which are slidably installed in the spiral groove 2215 of the disc-shaped drive disk 2212; the inner end of the drive rod 2214 is provided with a drive gear 2218, which meshes with the toothed ring 2216, and the outer end of the drive rod 2214 extends out of the turntable 11. When the drive rod 2214 is rotated, the drive rod 2214 drives the drive gear 2218 to rotate. The drive gear 2218 drives the disc-shaped drive disk 2212 to rotate through the engagement of the gear ring 2216. The disc-shaped drive disk 2212 drives the slider 2213 to move inward or outward through the engagement of the spiral groove 2215 and the sliding tooth 2217. The slider 2213 ultimately drives the claw bar 222 to move inward or outward. This structure enables the three claw bars 222 to move synchronously. When the drive gear 2218 is stopped rotating, the disc-shaped drive disk 2212 will stop rotating, and the spiral groove 2215 of the disc-shaped drive disk 2212 will lock the sliding tooth 2217 to prevent the slider 2213 from moving.

[0034] like Figures 4-7 As shown, the turntable 11 is also provided with a support roller 23 and a drive rod support block 24. The support roller 23 is used to support the middle part of the claw rod 222. The drive rod support block 24 is provided with a support block through hole.

The bearing can move inward or outward in the radial direction. The screw drive mechanism 324 is preferably a manual screw drive mechanism. The first motor 325 and the reducer 326 are respectively mounted on the first slide 323. The power output shaft of the first motor 325 is connected to the reducer 326, and the power output shaft of the reducer 326 is connected to the first gear 327. When the first slide 323 moves outward along the radial direction of the slewing bearing to a set position, the first gear 327 can mesh with the internal teeth of the inner ring 200 of the slewing bearing to drive the inner ring 200 of the slewing bearing to rotate. Thus, during the oil filling operation, the first gear 327 of the first inner ring drive device 32 is brought closer to the inner ring 200 of the support, the first motor 325 drives the reducer 326 to work, the reducer 326 drives the first gear 327 to rotate, and the first gear 327 drives the inner ring 200 of the support to rotate; while when the oil filling and sealing ring installation operations are stopped, the first gear 327 of the first inner ring drive device 32 is moved away from the inner ring 200 of the slewing bearing.

The sealing strip passing through the sealing strip channel 4211 of the guide wheel pair 421 can pass through the guide groove 4221 and reach the position of the annular sealing strip mounting groove 400 of the slewing bearing. The sealing strip glue applicator 43 includes two syringe positioners 431 and two glue applicator syringes 432. The syringe positioners 431 are installed on one side of the guide rod 422, and the glue applicator syringes 432 are installed on the corresponding syringe positioners 431. The glue applicator syringes 432 can apply glue to the sealing strip that has passed through the guide rod 422. With the cooperation of guide wheel 421 and guide rod 422, the sealing strip can be accurately guided into the annular sealing strip mounting groove 400 of the slewing bearing. By applying glue with glue syringe 432, glue can be applied to both sides of the sealing strip.
