Description

Technical Field

[0001] The invention relates to the technical field of bearing inner ring processing, in particular to a bearing inner ring processing device. Background Art

[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy.

[0003] During the processing of bearings, burrs and other protrusions are easily generated on the processed surface, which are generally generated on the inner ring of the bearing. This is because the range of processing equipment is limited during the processing of the inner ring, which leads to a decrease in processing accuracy. Therefore, in order to facilitate the later installation, the burrs on the inner ring need to be removed, mainly by scraping. Scraping refers to the use of a scraper or a scraper to scrape off trace metal on the surface of the processed workpiece to improve the surface shape accuracy and improve the contact condition between the mating surfaces. Scraping is an important method for the final finishing of various surfaces in mechanical manufacturing and repair.

[0004] In the traditional scraping process, a scraper or a scraper disc is used to make uniform contact along the inner ring of the bearing, and the burrs on the inner ring are scraped off by friction. The scraped chips will splash outward along the direction of the cutter's movement trajectory. Due to the limited range of the bearing inner ring, the splashed chips will splash and adhere to the inner wall of the inner ring and the support table that supports the bearing. There are many gaps on the support table surface, which affects the subsequent cleaning work. Therefore, in order to avoid the above problems, protective equipment is generally used to protect the outside of the scraper or scraper disc to block the splashing chips. However, the splashing chips will still adhere to the inner wall of the protective equipment, and after a long period of accumulation, they will still adhere to the inner ring of the bearing for a second time, not only requiring secondary cleaning later, but also blocking the inner ring area after scraping, affecting the operator's judgment.

[0005] In order to deal with the above problems, a bearing inner ring processing equipment is urgently needed. Summary of the invention

The screw rod is driven to rotate by the clamping motor, and the rotating screw rod drives the clamping plate to move horizontally along the top end of the turntable and fit with the outer side of the bearing.

[0010] As a further improvement of the technical solution, the inner ring of the bearing is sleeved on the outside of the inner ring, with its bottom end affixed to the top of the outer ring, and its inner ring inner wall is aligned with the inner wall of the outer ring along the vertical direction.

[0011] As a further improvement of the present technical solution, the limit frame includes an outer frame, which is arranged on the side of the scraper, and the end of the outer frame protrudes outward from the side of the top cover, and during the downward movement of the scraper disc, the protruding area contacts the inner ring in advance, and the reaction force provided by the inner ring is used to synchronously drive the scraper to move up.

[0022] See also Figure 1-Figure 2 As shown, a bearing inner ring processing device is provided, comprising a base 10 and an adjusting arm 30 installed on one side of the top of the base 10, the base 10 comprises a turntable 120 for placing the bearing to be processed and a driving assembly for driving the turntable 120 to rotate evenly, a clamping assembly for fixing the bearing to be processed is arranged at the top of the turntable 120, the adjusting arm 30 comprises a positioning motor 310 and a hydraulic rod 320 arranged at the top of the positioning motor 310, a scraping disc 311 is arranged at the bottom of the positioning motor 310, an outer ring 140 is arranged at the middle position of the top of the turntable 120, an inner ring 141 is arranged inside the outer ring 140, and a gap is reserved between the inner side of the outer ring 140 and the outer side of the inner ring 141 for collecting debris generated after scraping; A protective assembly 20 is disposed outside the scraper disc 311. The protective assembly 20 includes a top cover 210 and a protective frame 220 disposed at the bottom end of the top cover 210. The protective frame 220 is sleeved outside the scraper disc 311, and its side opening is in contact with the outer wall of the inner ring 141, forming a closed protective chamber outside the scraper disc 311 to block flying scraps. A scraper 231 is set on the inner side of the top of the protective frame 220, and a reset component is connected between the scraper 231 and the protective frame 220. A limit frame 230 is set on the side of the scraper 231. When it moves downward following the scraping disk 311, the limit frame 230 cooperates with the reset component to drive the scraper 231 to move upward to the top position on the inner side of the protective frame 220. After the scraping work is completed, the entire protective component 20 is detached, and the reset component is used to drive the scraper 231 to move downward to scrape the area where the inner wall of the protective frame 220 passes.

[0023] In the process of scraping the inner ring of the bearing, the bearing to be processed is first placed at the top position of the turntable 120, and fixed to the top position of the outer ring 140 by the clamping assembly. At this time, the positioning motor 310 is adjusted to the position of the inner ring of the bearing in cooperation with the hydraulic rod 320, so that the outer wall of the scraping disc 311 is attached to the inner ring of the bearing, and the positioning motor 310 is started to drive the scraping disc 311 to rotate, and the friction force is used to remove the burrs remaining in the inner ring area of ​​the bearing in contact with it; In the process of moving the position of the positioning motor 310, the limit frame 230 on the outside of the scraper disk 311 contacts the top of the outer ring 140 in advance, and cooperates with the reset component to drive the scraper 231 to move to the top position of the inner side of the guard frame 220. At this time, the entire guard frame 220 cooperates with the inner ring of the bearing to form a protective chamber on the outside of the scraper disk 311 to block the chips generated during the scraping process. The top of the protective chamber is blocked by the top cover 210, and the bottom is connected to the gap reserved between the inner side of the outer ring 140 and the outer side of the inner ring 141. The chips that have lost some kinetic energy will flow along the The protective chamber falls to the inner end of the gap, and this part of the chips is collected and processed. The remaining chips will adhere to the inner wall of the protective frame 220 and the inner ring area of ​​the bearing. After the chip cutting work is completed, the hydraulic rod 320 drives the adjustment motor 310 away from the scraping position. At this time, under the action of the reset component, the scraper 231 at the top is driven from top to bottom to scrape off the chips adhered to the passing area. Since the bottom end of the entire protective frame 220 is still aligned with the gap during this process, the scraped chips will fall along the bottom end of the protective frame 220 to the inner end of the gap.

[0024] In addition, the driving assembly includes a fixed platform 110 and a toothed disc 111 arranged on one side of the top of the fixed platform 110. The fixed platform 110 is arranged at the bottom of the rotating disc 120, and the bottom of the rotating disc 120 is rotatably connected to the top of the fixed platform 110. A gear shaft 121 is coaxially connected to the bottom of the rotating disc 120, and the gear shaft 121 is meshed with the toothed disc 111. A servo motor is arranged at the bottom of the toothed disc 111. Since the scraping work of the inner ring of the bearing requires uniform treatment of each area so that the connecting area of ​​the inner ring remains smooth for later installation work, during the specific scraping work, it is necessary to cooperate with the servo motor to drive the toothed disc 111 to rotate, and the toothed disc 111 drives the turntable 120 to rotate evenly along the top of the fixed table 110, so as to cooperate with the clamping assembly to drive the bearing to rotate synchronously, so that different areas of the inner ring of the bearing are contacted with the scraping disc 311 in turn, and the inner ring is evenly scraped by the scraping disc 311.

[0025] Furthermore, the clamping assembly includes a plurality of clamping motors 130 and a clamping plate 131 arranged at the end position of the clamping motor 130. Each clamping motor 130 array is arranged on the top side of the turntable 120. A screw rod is coaxially connected to the side of the clamping motor 130. The clamping plate 131 is threadedly connected to the screw rod. The screw rod is driven to rotate by the clamping motor 130, and the rotating screw rod drives the clamping plate 131 to move horizontally along the top of the turntable 120 and fit with the outer side of the bearing.

[0026] When used specifically, Figure 2As shown, in the process of fixing the bearing, since the processing position is the inner ring of the bearing, the fixing position needs to be set on the outside of the bearing. First, the bearing is placed at the top position of the turntable 120, and each clamping motor 130 is started synchronously. The screw connected to it is driven to rotate by the clamping motor 130, and the clamping plate 131 is driven to slide horizontally along the top of the turntable 120, and gradually approach the outside of the bearing until it fits therewith. The bearing is fixed at the top position of the turntable 120 so that it can rotate synchronously with the turntable 120, and the different positions of the inner ring are adjusted to contact with the clamping plate 131.

[0027] Furthermore, the inner ring of the bearing is sleeved on the outside of the inner ring 141, with its bottom end attached to the top of the outer ring 140, and the inner wall of the inner ring is aligned with the inner wall of the outer ring 140 along the vertical direction.

[0028] During specific use, in order to improve the collection effect of the gap, the inner ring wall of the bearing is aligned with the inner wall of the outer ring 140 in the vertical direction to reduce the obstruction of the chips falling. If the inner walls of the two are not aligned, there will be a protruding area at the top of the outer ring 140, causing some chips to fall into the protruding area, affecting the collection effect of the gap.

[0029] Since the scraper 231 is located at the inner end of the guard frame 220, during the scraping process, if the initial position of the scraper 231 is at the bottom wall of the inner end of the guard frame 220, its top end will form a protrusion on the inner wall of the guard frame 220 to prevent the chips from falling. Specifically, the limit frame 230 includes an outer frame 234, which is arranged on the side of the scraper 231, and the end of the outer frame 234 protrudes outward from the side of the top cover 210, and during the downward movement of the scraper disc 311, the protruding area contacts the inner ring 141 in advance, and the reaction force provided by the inner ring 141 is used to synchronously drive the scraper 231 to move upward; In order to circumvent the above problems, Figure 6 As shown, a protrusion is formed on one side of the bottom end of the top cover 210 by setting an outer frame 234. When the protective frame 220 moves downward synchronously with the scraper disk 311, the protruding area contacts the top of the inner ring 141 in advance. During the contact, the top of the inner ring 141 will exert a reaction force on the outer frame 234, causing the outer frame 234 to move upward in the opposite direction of the movement direction of the protective frame 220 until it moves to the top inner side of the protective frame 220, and cooperates with the top cover 210 to form a shield at the top of the protective chamber formed to prevent chips from flying upward.

[0030] In addition, the reset assembly includes a pair of plug rods 224 and a reset spring 225 sleeved on the outside of each plug rod 224. Side grooves 222 are provided on both sides of the guard frame 220. The two plug rods 224 are respectively located at the inner end positions of the two side grooves 222. The two sides of the outer frame 234 slide along the outside of the two plug rods 224, and the bottom end of the outer frame 234 is connected to the top end of the reset spring 225 at the corresponding position. Depend on Figure 5As shown, when the bottom end of the outer frame 234 contacts the top end of the inner ring 141, the outer frame 234 will synchronously drive the scraper 231 to move upward under the action of the reaction force, so that the outer frame 234 slides upward along the two insertion rods 224, and drives each reset spring 225 to stretch upward synchronously. After the scraping work is completed, the adjustment motor 310 and the protective component 20 are driven to move upward away from the scraping position under the action of the hydraulic rod 320. During this process, the outer frame 234 loses the action of external force, and the reset spring 225 drives the outer frame 234 and the scraper 231 to slide along the inner wall of the guard frame 220, and scrapes off the chips adhered to the inner wall area of ​​the guard frame 220, so that the inner wall of the guard frame 220 is in a clean state, reducing the subsequent cleaning work.

[0031] Furthermore, a pair of baffles 232 are disposed on both sides of the outer frame 234 . The two baffles 232 on the same side slide along the two sides of the side groove 222 at corresponding positions, and the cross-sectional dimensions of the baffles 232 are consistent with the cross-sectional dimensions of the side surfaces of the side groove 222 .

[0032] During specific use, in order to ensure that the outer frame 234 can slide up and down freely, it is necessary to set gaps on both sides of the side groove 222, and the formed gaps will be connected to the protective chamber, and the flying chips can easily escape from the gaps. At this time, the gaps on both sides are sealed by the baffle 232. When the outer frame 234 moves to the highest point of the protective frame 220, the baffle 232 is just aligned with the gap, and the gap is sealed to improve the shielding effect of the protective chamber. In the process of the protective frame 220 leaving the scraping area, the scraper 231 and the baffle 232 are synchronously driven downward by the outer frame 234, so that the scraper 231 is reset to the bottom end position inside the protective frame 220, and the chips are scraped off the passing area. At this time, the bottom end of the baffle 232 protrudes to the bottom end position of the protective frame 220.

[0033] Since in the process of forming protection for the scraper disk 311 by the protective frame 220, the two ends of the protective frame 220 are respectively fitted with the inner ring of the bearing, and the inner ring of the bearing is an arc-shaped structure, during the fitting process, a gap is easily formed in the connection area between the two, resulting in leakage of some chips, affecting the protection effect of the protective frame 220. Furthermore, the protective frame 220 is provided with side openings at both ends of the side surface close to the inner ring of the bearing, and the side openings are connected with the inner ends of the side grooves 222, and a wiping plate 221 is provided at the inner end of the side opening, and a wedge plate 223 is provided on the side of the wiping plate 221 close to the side groove 222, and an air bag is connected between the wiping plate 221 and the wedge plate 223, and a push plate 233 is connected between the top ends of the two baffles 232 on the same side, and the inclined surface of the push plate 233 is kept in contact with the inclined surface of the wedge plate 223 to slide; Depend on Figure 5As shown, during the upward movement of the scraper 231, the baffle plate 232 will be synchronously driven to move upward, and the push plate 233 will be driven to move vertically upward along the inclined surface of the wedge plate 223. Since both are wedge-shaped structures, during the upward and downward movement of the push plate 233, the wedge plate 223 will be gradually pushed to move horizontally toward the side opening, and the air bag will be squeezed so that the gas discharged from it will flow into the inner end of the wiper plate 221, so that the wiper plate 221 is in an expanded state, so as to be tightly attached to the inner ring of the bearing, fill the gap between the end of the protective frame 220 and the inner ring of the bearing, and improve the sealing effect of the protection chamber. At the same time, since the expanded wiper plate 221 is tightly attached to the inner ring of the bearing, the friction resistance formed between the wiper plate 221 and the inner ring of the bearing during the rotation of the inner ring of the bearing will drive the side of the wiper plate 221 to scrape off the chips adhered to the area where the inner ring of the bearing passes, so that the area after the scraping of the inner ring of the bearing is unobstructed, which is convenient for the operator to observe.
