Description

Technical Field

[0001] The present invention relates to the technical field of cage processing, and more specifically, it relates to a disassembly tool for a bearing cage. Background Art

[0002] As a key component of various mechanical equipment, the performance and quality of bearings play a crucial role in the overall operation of the equipment. And the bearing cage, as an important part of the bearing, can not only evenly separate the rolling elements in the bearing, reduce the friction and wear between the rolling elements, but also guide the rolling elements to roll on the correct track to ensure the stable operation of the bearing. During the production and manufacturing process of bearings, it is often necessary to disassemble the bearing cage for subsequent processing, inspection, repair or replacement, etc.

[0003] During the disassembly process of the bearing cage, due to factors such as the characteristics of the processing technology and the working environment, debris will inevitably remain on the upper surface of the outer clamping tire cover and the upper surface of the cage. Some of these debris comes from the metal chips generated during the previous processing operations such as cutting and grinding of the bearing or cage, and adheres to the surface due to untimely and incomplete cleaning.

[0004] In the subsequent processing, inspection and assembly operations of the cage, the debris may be displaced due to external micro-interference. When the outer clamping tire cover comes into contact with the cage again or relative movement occurs, the debris is extremely likely to be embedded in the surface of the cage, resulting in damage such as scratches and pits. Specifically, the surface damage of the cage will change the microscopic morphology and stress distribution of the cage surface, increasing the friction force and uneven distribution when the rolling elements roll in the cage. And the stable rolling of the rolling elements is the key to ensuring the rotation accuracy of the bearing, and abnormal friction will directly affect the rotation accuracy of the bearing. In this state for a long time, the wear of each component inside the bearing is aggravated, the fitting accuracy is reduced, and ultimately the service life of the bearing is greatly shortened. Summary of the Invention

Detailed implementation manners

[0019] Now, the subject matter described herein will be discussed with reference to exemplary embodiments. It should be understood that discussing these embodiments is only to enable those skilled in the art to better understand and thus implement the subject matter described herein. Without departing from the scope of protection of the content of this specification, changes can be made to the functions and arrangements of the elements discussed. Each example can omit, substitute, or add various processes or components as needed. Additionally, the features described relative to some examples can also be combined in other examples.

[0020] According to the attached Figure 1 and the attached Figure 2 As shown, a disassembly tooling for a bearing cage includes a tooling body 100. The tooling body 100 includes a base 110, and a centering component 120 and a support base 130 are provided on the base 110. The centering component 120 is located inside the support base 130, and the bearing cage is placed on the support base 130.

[0021] Specifically, as shown according to the attached Figure 2 The centering component 120 includes a dust cover installed on the base 110, and a centering seat is provided inside the dust cover. The centering seat is fixedly connected to the base 110, and a plurality of centering claws are provided on the centering seat.

[0022] In this embodiment, the centering range of the centering component 120 is wide. The same centering claw can cover a diameter difference of 10 mm - 20 mm, and more diameter ranges can be covered by replacing the centering claws. In addition, the centering claws are designed as arc surfaces to ensure that the positioning surface forms an arc contact with the cage, reducing the contact surface and reducing bruising while ensuring centering accuracy. At the same time, the dust cover can prevent machining chips and debris from entering the centering component 120 and affecting the centering accuracy.

[0023] Among them, as shown according to the attached Figure 2As shown, the support seat 130 includes a pad installed on the base 110, and a plurality of support points are evenly distributed in a ring shape on the pad. The support points are designed to be rectangular blocks of equal size, which reduces the contact area between the positioning seat and the retaining frame and prevents the bottom contact surface from being too large, effectively solving the risk of the bottom contact being too large and damaging the retaining frame surface when the bottom surface is cut.

[0024] According to the attached Figure 1 and attached Figure 2 As shown, the tooling body 100 also includes an outer card tire cover 140, and a grabbing platform 150 is symmetrically installed on the outer card tire cover 140, two groups of positioning columns 160 are symmetrically installed on the base 110, and two groups of positioning holes that are compatible with the positioning columns 160 are opened on the outer card tire cover 140, and the positioning columns 160 and the positioning holes are snap-fitted. Multiple groups of cylinders 170 are installed on the base 110, and a flip assembly 200 is provided at the telescopic end of the cylinder 170.

[0025] In the specific implementation, the base 110 is placed on the workbench of the five-axis machine, and then the centering assembly 120 is installed on the base 110, the support seat 130 is fixed, and the positioning column 160 is installed on the base 110. Subsequently, the retaining frame is placed on the support seat 130, the outer card tire cover 140 is placed on the retaining frame, and the direction and position of the positioning column 160 are noted. The grabbing table 150 of the automated claw is installed, and the cylinder 170 is turned on to control the flip assembly 200 to press the outer card tire cover 140, and the processing begins.

[0026] After the processing is completed, the pressure point of the cylinder 170 leaves the outer card tire cover 140, and the automatic robot clamps the gripping table 150 to take down the outer card tire cover 140 and remove the cage, and a processing cycle is completed, which effectively solves the technical problems of the original centering cage designing a positioning plate for each model, resulting in cost waste, and the positioning plate's entire surface is in contact with the cage's inner diameter, often causing the inner diameter surface to be scratched due to the residual cutting of the positioning surface. When continuous processing is required, repeat the above steps to process another piece.

[0027] According to the attached Figure 3 To Attachment Figure 5 , and attached Figure 7 and attached Figure 8As shown, the flipping assembly 200 includes a base 201 mounted on the telescopic end of the cylinder 170. A clamping plate 202 is provided on the base 201. A connecting shaft 203 is mounted on the clamping plate 202, and the connecting shaft 203 is rotatably connected to the base 201 through a bearing. Swing arms 204 are symmetrically mounted on the connecting shaft 203, and a sliding groove 205 is formed in the swing arm 204. A sliding rod 206 is slidably connected in the sliding groove 205. A connecting frame 207 is provided at the telescopic end of the cylinder 170, and the connecting frame 207 is fixedly connected to the sliding rod 206. A connecting plate 208 is mounted at one end of the connecting frame 207 away from the clamping plate 202. This design enables the clamping plate 202 to achieve flexible flipping actions, meeting the requirements of multi-angle fixation and flipping of the cage in different processing technologies, and improving the adaptability of the tooling during the processing process.

[0028] It should be understood that when driving the connecting frame 207 to move, the connecting frame 207 drives the sliding rod 206 to move synchronously, causing the sliding rod 206 to move in the sliding groove 205, driving the swing arm 204 to rotate, so that the clamping plate 202 rotates while the connecting shaft 203 rotates, driving the clamping plate 202 to perform a flipping motion.

[0029] Specifically, a first rack plate 209 is provided in the base 110, and one end of the first rack plate 209 passes through the base 110 and is fixedly connected to the connecting plate 208. A gear 210 is meshed with the first rack plate 209, and a first rotating shaft 211 is installed in the gear 210. The first rotating shaft 211 is rotatably connected to the inner wall of the base 110 through a bearing. A second spring 227 is provided on the first rack plate 209, and one end of the second spring 227 is fixedly connected to the connecting plate 208, and the other end of the second spring 227 is fixedly connected to the base 110. The second spring 227 provided on the first rack plate 209 plays a key buffering role. When the cylinder 170 drives the connecting frame 207 and related components to act, the spring can absorb the instantaneous impact force, avoiding damage to the entire flipping assembly 200 due to too fast movement or external impact, effectively extending the service life of the tooling, and ensuring its stability and reliability during long-term use.

[0030] The elastic force of the second spring 227 enables the first rack plate 209 and the connecting plate 208 to automatically reset after the action is completed without manual intervention. This automatic reset function prepares for the next action, greatly simplifies the operation process, improves the processing efficiency, and ensures the coherence of the processing process, especially suitable for processing tasks that require frequent flipping operations.

[0031] According to the appendix Figure 7 and the appendix Figure 8As shown, a driving ring 212 is also rotatably connected inside the base 110 through a bearing. A plurality of arc-shaped internal racks 213 are installed on the inner wall of the driving ring 212. The internal racks 213 are meshed and connected with the gear 210. An arc-shaped external rack 214 is installed on the outer wall of the driving ring 212. A second rack plate 215 is meshed and connected with the external rack 214. An electric push rod 216 is installed inside the base 110, and the telescopic end of the electric push rod 216 is fixedly connected with the second rack plate 215.

[0032] It should be noted that when the electric push rod 216 is driven to move, the electric push rod 216 controls the second rack plate 215 to move, so that the second rack plate 215 is meshed and connected with the external rack 214, causing the driving ring 212 to rotate. Through the meshing connection between the gear 210 and the internal rack 213, the gear 210 is controlled to rotate, and the first rack plate 209 is controlled to move, so that the plurality of connecting frames 207 move synchronously closer or farther away, thereby facilitating the flipping movement of the driving clamping plate 202.

[0033] According to the attached Figure 6 As shown, a ventilation pipe 217 is slidably connected inside the clamping plate 202. A suction cup 218 is installed on the ventilation pipe 217. A first spring 219 is provided on the ventilation pipe 217. One end of the first spring 219 is fixedly connected with the ventilation pipe 217, and the other end of the first spring 219 is fixedly connected with the clamping plate 202. A second rotating shaft 220 is connected by a bearing inside the clamping plate 202, and a cam 221 is installed on the second rotating shaft 220. A backing plate 222 is installed on the ventilation pipe 217, and the backing plate 222 is in contact with the outer surface of the cam 221.

[0034] During operation, the cam 221 rotates to squeeze the backing plate 222. When the cam 221 rotates one week, the backing plate 222 drives the ventilation pipe 217 to move up and down as the cam 221 rotates. When the cam 221 rotates continuously, the ventilation pipe 217 moves up and down in a jittering manner to shake off the debris on the outer tire cover 140.

[0035] Furthermore, according to the attached Figure 6 As shown, a ventilation chamber 223 is also installed on the clamping plate 202. An impeller 224 is provided inside the ventilation chamber 223. One end of the second rotating shaft 220 passes through the ventilation chamber 223 and is fixedly connected with the impeller 224. An air inlet 225 is opened at one end of the ventilation chamber 223, and an air outlet 226 is opened at the other end of the ventilation chamber 223. Through the settings of the air inlet 225 and the air outlet 226, air flows in through the air inlet 225, drives the impeller 224 to rotate, and then is discharged through the air outlet 226, thereby facilitating the continuous rotation of the impeller 224.

[0036] Among them, in other embodiments, an air pump is provided between the vent pipe 217 and the air inlet 225. Connecting air pipes are installed at both the input end and the output end of the air pump. The ends of the connecting air pipes away from the air pump are respectively connected to the vent pipe 217 and the air inlet 225. Additionally, a shunt joint can be provided at the input end and the output end of the air pump. The shunt joint is connected to the connecting air pipe, and the connecting air pipes on each shunt joint are respectively connected to the vent pipe 217 and the air inlet 225, so that one air pump can be used to control the suction cups 218 and the impellers 224 on all the clamping plates 202 to work. Moreover, a branch pipe can be provided on the connecting air pipe connected to the vent pipe 217, and a one-way valve is provided in the branch pipe, so that when the air pump supplies air continuously to the inside of the ventilation chamber 223, the outside air flow can be inhaled through the branch pipe.

[0037] In other embodiments, the clamping plate 202 is used to drive the suction cup 218 to adjust the angle, and the air pump is controlled to supply air in the reverse direction, so that air is blown into the suction cup 218, thereby facilitating the cleaning of the debris on the tooling body 100 and removing the debris to avoid damage to the cage. This design endows the tooling with an additional cleaning function, can clean various parts of the tooling body 100, avoid damage to the cage caused by debris residue, and further improves the applicability and reliability of the tooling. Additionally, this air circuit system integrates multiple functions such as the adsorption of the suction cup 218, the drive of the impeller 224, the air flow cleaning, and the air blowing and cleaning. Without adding too many complex structures, it realizes the diversification of the tooling functions and improves the overall performance and use value of the tooling.

[0038] The above describes the embodiments of the specific implementation manner, but this embodiment is not limited to the above specific implementation manner. The above specific implementation manner is merely illustrative and not restrictive. Under the inspiration of this embodiment, those of ordinary skill in the art can also make many forms, all of which fall within the protection scope of this embodiment.
