Description

Technical Field

[0001] This utility model relates to the field of cutting processing equipment technology, specifically a cutting processing equipment for the inner and outer walls of a sliding bearing. Background Technology

[0002] Sliding bearings, also known as bushings, sleeves, or sleeve bearings, are typically cylindrical and do not contain moving parts. During the manufacturing process, sliding bearings require the use of cutting equipment to cut the inner and outer walls of the bearing so that the cut bearing meets dimensional requirements.

[0003] According to the patent application CN221389195U, "This utility model discloses a sliding bearing inner and outer wall cutting processing device, which relates to the field of sliding bearing cutting technology. It includes a worktable, a first groove on the side of the worktable, a movable frame slidably connected to the surface of the first groove, a first movable block slidably connected to the surface of the second groove, a fixed block fixedly connected to the upper surface of the first movable block, a third groove on the upper surface of the fixed block, a second movable block slidably connected to the surface of the third groove, a tool holder fixedly connected to the upper surface of the second movable block, a cutting tool mounted on the surface of the tool holder, and a driving device mounted on the upper surface of the worktable. This utility model, through the arrangement of the fixed block, the second movable block, the tool holder, and the cutting tool, can simultaneously cut the inner and outer walls of the bearing, improve the cutting speed, and achieve the purpose of improving work efficiency. The arrangement of the groove, scraper, and spring facilitates the cleaning and collection of iron filings generated during the processing."

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] During use, this utility model uses a chuck to fix the bearing and a lead screw to adjust the position of the cutting tool, enabling simultaneous cutting of the inner and outer walls of the bearing. The moving frame can scrape iron scraping from the worktable surface to both sides. However, in actual use, because the tool holder and the cutting tool are set at a perpendicular angle, this cutting device can only perform grooving cutting on the bearing. When chamfering the edge of the bearing is required, other machines must be used, resulting in low applicability. Therefore, an improved cutting device for the inner and outer walls of sliding bearings is needed to solve these problems. Utility Model Content

[0031] Furthermore, the bottom of the sliding limit bar 217 is fixedly installed with the top of the movable frame plate 213, and the top of the limit rod 214 is fixedly installed with the bottom of the top plate 1, so as to facilitate normal adjustment of the position of the cutting tool body 218.

[0032] Furthermore, the outer wall adjusting cutting assembly 22 includes a second cylinder 221, which is fixedly installed on the top of the movable frame plate 213. A movable tool holder 222 is fixedly installed on the front of the second cylinder 221, and a third cylinder 223 is fixedly installed on the right side of the movable tool holder 222.

[0033] Furthermore, gear 227 meshes with rack 2210, and movable tool holder 222 is slidably mounted on the outside of sliding limit bar 217, facilitating normal adjustment of cutting tool body 226.

[0034] Example 2:

[0035] Please see Figure 5Furthermore, in conjunction with Embodiment 1, the auxiliary rotation mechanism 3 includes a rotation limit block 31, which is fixedly installed on the top of the top plate 1. A rotating shaft 32 is rotatably installed inside the rotation limit block 31. A chuck body 33 is fixedly installed on the left side of the rotating shaft 32. A second motor 34 is fixedly installed at the bottom of the top plate 1. A transmission roller 35 is fixedly installed on the right side of the transmission shaft of the second motor 34 and the right side of the rotating shaft 32. A transmission belt 36 is installed on the outside of the transmission roller 35 to facilitate the rotation of the sliding bearing through the auxiliary rotation mechanism 3.

[0037] In actual operation, when this device is used, the sliding bearing is first fixed by the chuck body 33. Then, the drive motor 211 causes the threaded rod 212 to move the movable frame plate 213 under the restriction of the limit rod 214, sending the cutting tool body 226 and the cutting tool body 218 to the back and inside of the sliding bearing. At this time, the drive cylinder 215 causes the movable tool holder 216 to move the cutting tool body 218 to press against the inner wall of the sliding bearing. The drive cylinder 221 causes the movable tool holder 222 to move the cutting tool body 226 to press against the outer wall of the sliding bearing. At this time, the drive motor 34, along with the transmission roller... Driven by the transmission belt 36, the chuck body 33 drives the sliding bearing to rotate. At this time, the first cylinder 215 and the second cylinder 221 are driven to move closer to the inside of the sliding bearing, so that the inner and outer walls of the sliding bearing can be processed simultaneously. When the outer wall of the sliding bearing needs to be chamfered, the second threaded rod 228 is rotated to move the moving slotted plate 229. The moving slotted plate 229 drives the rack 2210 to move, so that the gear 227 drives the second cutting tool body 226 to rotate. At this time, the third cylinder 223 is driven to make the second cutting tool body 226 stick to the edge of the outer wall of the sliding bearing, so that the chamfering cutting process can be performed.
