Description

Technical Field

[0001] This invention relates to the field of polishing technology, and in particular to an internal and external polishing device based on bearing processing. Background Technology

[0002] Existing polishing equipment often faces the following problems in bearing processing.

[0003] First, most equipment can only polish a single outer or inner surface, and cannot complete the polishing of both the inner and outer surfaces at the same time, resulting in low processing efficiency and requiring multiple clamping and adjustment, which increases the complexity of operation.

[0004] Secondly, the polishing belt support structure is unstable and is prone to vibration or displacement during high-speed polishing, affecting polishing accuracy and surface smoothness. Especially for high-precision bearing processing, existing equipment is difficult to achieve stable support.

[0005] In addition, material clamping mechanisms often lack adaptive adjustment functions. For bearing workpieces of different specifications, unstable clamping can easily lead to uneven polishing or workpiece displacement, affecting processing consistency and quality.

[0018] Compared with the prior art, the beneficial effects of the present invention are: 1. This equipment integrates components such as a base plate, mounting plate, mounting frame, cross-groove rod, nested rod, arc-shaped auxiliary rod, polishing belt, secondary polishing belt, rectangular rod, inner polishing plate, and materials. It enables simultaneous polishing of the inner and outer surfaces of bearings, allowing the polishing belt and secondary polishing belt to work together for both coarse and fine grinding of the material's outer surface. This eliminates the need for multiple clamping and adjustments, significantly improving processing efficiency. This design solves the problem of existing equipment being unable to simultaneously handle inner and outer polishing. It boasts a high degree of automation, adapts to different working conditions, and ensures a continuous and efficient polishing process, thereby improving the overall quality and output speed of bearing processing.

[0019] 2. This equipment utilizes a sliding design with cross-shaped sliding rods and nested rods to achieve real-time adjustment of the polishing belt support radius. The circumferential structure of the nested rods and arc-shaped auxiliary rods, combined with the telescopic rod's extension and retraction, allows the polishing belt to closely conform to workpieces of different specifications, improving polishing accuracy and surface smoothness. This not only solves the problem of low efficiency but also reduces vibration through stable support, ensuring a smooth polishing process. It further optimizes the workflow, enhances the equipment's versatility, and is suitable for processing various bearing sizes.

[0020] 3. This equipment adjusts the height of the secondary polishing belt through a dual-axis motor, a second threaded rod, and a side plate. Combined with the auxiliary and main rotating shafts, it drives the polishing belt to circulate, solving the problem of unstable polishing belt support. Through the structural design of the secondary polishing belt, it ensures that the polishing belt maintains uniform tension during high-speed movement, reducing offset and vibration. At the same time, the reset mechanism of the first connecting rod and spring provides dynamic adjustment, allowing the polishing process to adapt to changes in the workpiece surface, improving polishing accuracy and surface quality, and effectively addressing the shortcomings of insufficient support in existing equipment.

[0021] 4. This equipment uses a first servo motor, a third threaded rod, and a second slide to drive the inner polishing plate to expand or contract, achieving stable clamping of materials. The circumferential design of the polishing plate and materials, combined with the rotational installation of the drive rod, ensures that bearing workpieces of different specifications are fixed in position during polishing, avoiding displacement or uneven grinding. This solves the problem of unstable material clamping, improves processing consistency and quality, and, in conjunction with the drive structure of the tension belt and arc plate, achieves automated material rotation, further ensuring the continuity and reliability of polishing operations.

Detailed Implementation

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figures 1 to 11 The present invention provides a technical solution: An internal and external polishing device based on bearing processing includes a base plate 1. A mounting plate 2 is fixedly mounted on the upper surface of the base plate 1. A mounting bracket 202 is fixedly mounted from the middle to the left rear of the upper surface of the mounting plate 2. A first connecting rod 203 is rotatably mounted on the upper middle part of the mounting bracket 202. A first spring 204 is fixedly mounted between the lower end of the first connecting rod 203 and the mounting bracket 202. Figure 3 As shown.

[0027] A second connecting rod 205 is rotatably mounted on the inner front end of the first connecting rod 203. A first mounting head 206 is rotatably mounted on the upper end of the second connecting rod 205. A third connecting rod 207 is fixedly mounted on the right side of the first mounting head 206. The right rear end of the third connecting rod 207 is rotatably mounted on the upper left side of the mounting bracket 202. Figure 3 As shown.

[0028] Therefore, a first threaded rod 208 is rotatably mounted on the upper end face of the first mounting head 206 to its internal thread. Then, a first pin 209 is slidably mounted from the inside to the outside of the first mounting head 206. The left end of the first pin 209 is rotatably connected to the first threaded rod 208 by a thread, and the right end of the first pin 209 passes through the third connecting rod 207. Figure 5 As shown, the right end of the first pin 209 is rotatably mounted with the first rotating shaft 210.

[0029] Therefore, during use, pressing the first threaded rod 208 will cause the third connecting rod 207 to rotate. The rotation of the third connecting rod 207 drives the second connecting rod 205 to rotate. After the second connecting rod 205 moves, it squeezes the first connecting rod 203, causing the first connecting rod 203 to rotate. After being released, the first spring 204 squeezed by the first connecting rod 203 will perform a reset operation, that is, move outward, thereby driving the first connecting rod 203 and thus resetting the overall structure.

[0030] Secondly, the first threaded rod 208 enables quick disassembly and installation of the first pin rod 209 and the first mounting head 206, facilitating subsequent structural maintenance and replacement.

[0031] A second mounting head 211 is fixedly mounted on the left side of the middle part of the mounting bracket 202. A second threaded head 212 is rotatably mounted on the upper end face of the second mounting head 211 to its internal thread. A second pin 213 is slidably mounted inside the second mounting head 211. The left end of the second pin 213 is rotatably connected to the second threaded head 212. The right end of the second pin 213 passes through the mounting bracket 202, and a cross-groove rod 214 is rotatably mounted on the right end of the second pin 213. Four first slides 218 are slidably mounted inside the cross-groove rod 214. An arc-shaped auxiliary rod 217 is fixedly mounted on the bottom end of each of the first slides 218. A first adjusting rod 216 is rotatably mounted on both ends of the inner side of the arc-shaped auxiliary rod 217. The end of the first adjusting rod 216 away from the arc-shaped auxiliary rod 217 is rotatably mounted on the outer circumferential surface of the nested rod 215. The nested rod 215 is slidably mounted on the outside of the cross-groove rod 214. Figure 6 As shown, it should be noted that a telescopic rod is fixedly installed at the front end of the cross-shaped sliding rod 214. The telescopic rod and the inner front end of the nested rod 215 are fixedly connected. The movement of the telescopic rod causes the nested rod 215 to slide.

[0032] Therefore, during the operation, the telescopic rod is extended and adjusted, causing the nested rod 215 to slide along the outside of the cross-shaped slide bar 214. When the nested rod 215 slides, the first slide table 218 of the arc-shaped auxiliary rod 217 is pushed by the first adjusting rod 216 to slide synchronously in the slide groove of the cross-shaped slide bar 214, so that the outer side of the arc-shaped auxiliary rod 217 expands outward.

[0033] At this point, the arc-shaped auxiliary rod 217 can closely fit the polishing belt 219 on the outer circumferential surface, providing a stable support base for subsequent polishing tool operations. This ensures that the work process and degree can be adjusted in real time according to the situation during polishing, thereby effectively improving polishing accuracy and surface smoothness. When it is necessary to change to polishing belts 219 of different specifications, the support radius of the arc-shaped auxiliary rod 217 can be quickly adjusted by controlling the extension length of the telescopic rod, achieving adaptation to polishing belts 219 of various sizes, significantly improving the versatility and work efficiency of the equipment. In addition, the structural design of the cross-groove rod 214 makes the sliding trajectory of the first slide table 218 more precise, further ensuring the fit between the arc-shaped auxiliary rod 217 and the surface of the polishing belt, providing double protection for the stability of the polishing operation.

[0034] It should be noted that the polishing belt 219 rotates along with the rotation of the first rotating shaft 210, the inside of the first rotating shaft 210 is the stator and the outside is the rotor.

[0035] Furthermore, adjustments can be made during the operation based on the actual situation, such as whether polishing belt 219 should be applied first, later, or simultaneously.

[0036] The upper right side of the mounting plate 2 is provided with a symmetrical first slide groove 201. A symmetrical dual-axis motor 3 is fixedly installed inside the two first slide grooves 201. A second threaded rod 301 is fixedly installed on the output shafts at both ends of the dual-axis motor 3. A second adjusting rod 302 is rotatably installed on the circumferential surface of two adjacent second threaded rods 301. A side plate 303 is rotatably installed on the upper inner side of the two second adjusting rods 302 located on the same side. A mounting connecting rod 304 is slidably installed on the outer rear end of the left and right side plates 303. It should be noted that the front half of the mounting connecting rod 304 is rotatably connected to the side plate 303 by a thread. During operation, the tension of the subsequent secondary polishing belt 306 can be adjusted according to the situation. Then, an auxiliary shaft 305 is rotatably mounted between the two mounting connecting rods 304 and inside the two side plates 303. A secondary polishing belt 306 is rotatably mounted on the outer circumferential surface of the auxiliary shaft 305. A main shaft 307 is rotatably mounted at the other end of the secondary polishing belt 306 and between the two side plates 303. A grooved wheel 308 is fixedly mounted at the left end of the main shaft 307 and outside the side plate 303. A track 309 is rotatably mounted on the circumferential surface of the grooved wheel 308. The output shaft of a stepper motor 310 is rotatably mounted at the other end of the track 309. The stepper motor 310 is fixedly mounted on the upper surface of the mounting plate 2 and the base plate 1. Figure 1 As shown.

[0037] Therefore, during use, the dual-axis motor 3 is started first, and its two output shafts drive the second threaded rod 301 to rotate, so that the adjacent second adjusting rod 302 moves synchronously along the direction of the first slide groove 201, thereby driving the adjustment of the height of the side plates 303 on the front and rear sides to adapt to bearing workpieces of different specifications and polishing operations.

[0038] Subsequently, by installing the rear half of the connecting rod 304 (the part that is threaded to the side plate 303), the tension of the secondary polishing belt 306 is adjusted to ensure that the polishing belt is in optimal working condition.

[0039] Next, the stepper motor 310 is started, and its output shaft drives the grooved wheel 308 to rotate through the track 309, which in turn drives the main shaft 307 to rotate, thereby making the secondary polishing belt 306 form a stable cyclic motion around the auxiliary shaft 305 and the main shaft 307.

[0040] At this point, the material 6 to be polished is placed on the subsequent structure for bonding and polishing with the secondary polishing belt 306 and polishing belt 219. The high-speed cyclic motion of the secondary polishing belt 306 and polishing belt 219 is used to perform coarse and fine polishing on the outer surface of the material 6.

[0041] During the polishing process, the speed of the dual-axis motor 3 or the tension of the mounting connecting rod 304 can be adjusted in real time according to the polishing effect of the workpiece to achieve the ideal polishing precision. The whole process is highly automated, which can effectively improve the efficiency and quality of bearing processing and meet the polishing requirements under different working conditions.

[0042] Finally, a rectangular rod 4 is fixedly mounted on the spindle of the stepper motor 310, located on the right side of the mounting bracket 202. Each of the four sides of the rectangular rod 4 has a second sliding groove 401. A first servo motor 402 is fixedly mounted at one end of each second sliding groove 401. A third threaded rod 403 is fixedly mounted on the output shaft of the first servo motor 402. A second slide 404 is rotatably mounted on the circumferential surface of the third threaded rod 403. A first drive rod 405 is rotatably mounted inside the second slide 404. An inner polishing plate 406 is rotatably mounted at one end of the outer side of the first drive rod 405. A second drive rod is rotatably mounted on the inner circumferential surface of the other end of the inner polishing plate 406. The other end of the second drive rod is rotatably mounted on the outer side of the rectangular rod 4. Figure 11 As shown, material 6 is slidably mounted on the outer side of the inner polishing plate 406.

[0043] Therefore, during use, the first servo motor 402 can be started according to the size of the material 6, and its output shaft drives the third threaded rod 403 to rotate, causing the second slide table 404 to move linearly along the second slide groove 401.

[0044] When the second slide 404 moves toward the first servo motor 402, the first drive rod 405 and the second drive rod push the inner polishing plate 406 to expand inward until it fits tightly against the inner surface of the material 6, thus achieving a stable clamping of the material 6. Conversely, when the second slide 404 moves away from the first servo motor 402, the first drive rod 405 and the second drive rod pull the inner polishing plate 406 to retract, thereby releasing the material 6 and facilitating the replacement or placement of the material 6.

[0045] During polishing, the clamping structure ensures that the material 6 always maintains a stable posture. Combined with the high-speed cyclic motion of the secondary polishing belt 306 and the polishing belt 219, it achieves all-round and uniform polishing of the outer surface of the material 6.

[0046] Meanwhile, by controlling the speed and direction of the first servo motor 402, the axial position of the material 6 can also be adjusted so that the polishing area covers the entire outer surface of the material 6, further improving the comprehensiveness and accuracy of polishing. The entire clamping and adjustment process does not require manual intervention and forms an efficient linkage with the polishing process, effectively ensuring the continuity and consistency of bearing processing.

[0047] Protective shells 5 are fixedly installed on both the front and rear sides of the base plate 1. A second servo motor 501 is fixedly installed on the outer side of each protective shell 5. A tensioning belt 502 is rotatably installed on the circumferential surface of the output shaft of the second servo motor 501 and inside the protective shell 5. A drive shaft 503 is rotatably installed on the other end of the inner side of the tensioning belt 502. An arc-shaped plate 505 is rotatably installed on the outer side of the drive shaft 503. The telescopic rod of a telescopic pump 504 is fixedly installed on the outer side of the arc-shaped plate 505. The telescopic pump 504 is fixedly installed on the outer side of the protective shell 5. Figure 10 As shown.

[0048] Therefore, during use, when the telescopic pump 504 is started, its telescopic rod will move the arc plate 505, and during the movement, it will move the drive shaft 503. This allows the tension belt 502 to move and tighten along with the drive shaft 503. Then, the second servo motor 501 is started, and the output shaft of the second servo motor 501 drives the tension belt 502 to rotate. The rotation of the tension belt 502 drives the drive shaft 503 to rotate, thereby allowing the material 6 to rotate through the drive shaft 503, thus completing the subsequent polishing operation.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
