Description

Technical Field

[0001] This utility model relates to the field of self-lubricating lathe shaft machining technology, specifically a cutting blade replacement device for self-lubricating lathe shaft machining. Background Technology

[0002] In the field of self-lubricating lathe shaft machining, trimming excess metal from both ends of shaft workpieces is a crucial process to ensure product accuracy and quality. However, the trimming equipment currently used in the industry is gradually revealing several problems in practical applications, making it difficult to meet the demands for efficient and stable machining. These problems are specifically manifested in the following aspects: Regarding the ease of replacing cutting blades, traditional equipment often uses multiple sets of bolts to directly fix the cutting blades to the rotating shaft. Disassembly and installation require the use of special tools to tighten each bolt individually, which is cumbersome and time-consuming. When the cutting blade needs to be replaced due to wear, dulling, or breakage after long-term use, it not only occupies a lot of production time and reduces processing efficiency, but may also cause the threads to strip due to repeated bolt disassembly, affecting the connection stability between the rotating shaft and the cutting blade, and creating a safety hazard for subsequent cutting operations. In addition, existing devices cannot fix lathe shafts of different sizes.

[0003] According to the description of a pipe cutting device published on the patent website (authorization announcement number: CN222874682U), the pipe cutting device includes "legs, base" etc., to achieve the cutting work.

[0004] Regarding the above description, the applicant believes the following issues exist: This pipe cutting device uses a stand and base to perform the cutting work. The device uses a cutting blade to perform the cutting work. However, the cutting blade and the mounting bracket are designed as an integrated unit, which cannot be easily disassembled. When the cutting blade needs to be replaced due to wear, dulling or breakage after long-term use, it cannot be replaced. Therefore, this device needs to be improved. Utility Model Content

[0013] Compared with the prior art, this utility model provides a cutting tool replacement device for self-lubricating lathe shaft machining, which has the following beneficial effects: 1. This cutting blade replacement device for self-lubricating lathe shaft machining, through a set cutting mechanism, when excess metal needs to be cut off at both ends during the machining of the self-lubricating lathe shaft, and after the fixing mechanism is completed, the first hydraulic cylinder drives the moving seat and the support frame to move rearward. As the moving seat moves, it slides around the guide rod, thus driving the cutting blade to move rearward. During this movement, the servo motor drives the rotating rod, positioning plate, cutting blade, and fixing plate to rotate. When the cutting blade contacts the right end of the shaft body, the cutting work can begin. The support frame then moves... When in operation, the protective frame drives the support roller to rotate on top of the fixed base. Under the action of the support roller, the moving base and the load-bearing frame are supported, ensuring the stability of the cutting blade. The cutting blade slides on the outer periphery of the rotating rod, and its right side is in contact with the left side of the positioning plate. After installation, the limit frame can be inserted into the cutting blade and the positioning plate. Finally, the fixed plate is threaded to the outer periphery of the left end of the rotating rod, so that the right side of the fixed plate is in contact with the left side of the limit frame, thus fixing the cutting blade. This makes installation and disassembly convenient. When the cutting blade wears out and breaks, it can be easily replaced. The operation is convenient.

[0014] 2. This self-lubricating lathe shaft machining cutting blade replacement device, through a fixed mechanism, when the self-lubricating lathe shaft needs to be cut at both ends during machining, firstly, the shaft body is placed inside the top of the first placement frame located on the left and right sides of the top of the moving table to ensure the initial stability of the shaft body. If the shaft body is too long, the second placement frame can further support the bottom left side of the shaft body to ensure balance and stability during placement. At this time, the third hydraulic cylinder can drive the clamping plate to move. When the clamping plate moves, it will drive the guide shaft to slide inside the support frame, so that the inner side of the clamping plate and the outer side of the shaft body come into contact with each other, forming a two-way fixation from top to bottom. This ensures the stability of the shaft body during the cutting work and avoids damage such as burrs and cracks at the cutting part due to the displacement of the shaft body. Then, the second hydraulic cylinder can drive the moving table to slide left and right inside the machining table, so that the right end of the shaft body to be cut is located behind the cutting blade, waiting for the cutting work to be carried out. This can achieve the fixation of shaft bodies of different sizes and lengths. Attached Figure Description

[0022] The right side of the fixing plate 396 is in contact with the left side of the limiting frame 395, which facilitates the fixing of the cutting blade 394 through the fixing plate 396.

[0023] Example 2 Please see Figure 1-6Furthermore, based on Embodiment 1, the fixing mechanism 4 further includes a second hydraulic cylinder 41, which is fixedly connected to the left side of the processing table 2. A movable table 42 is fixedly connected to the right side of the second hydraulic cylinder 41. The movable table 42 is slidably connected inside the processing table 2. A first placement frame 44 is fixedly connected to the top left and right sides of the movable table 42. The first placement frame 44 is located at the bottom of the shaft body 5. A support frame 43 is fixedly connected to the top of the movable table 42. A third hydraulic cylinder 45 is fixedly connected to the top of the support frame 43.

A second placement frame 49 is fixedly connected to the top of the connecting seat 48. The second placement frame 49 is located at the bottom of the shaft body 5.

[0024] The clamping plate 46, the top of the first placement frame 44, and the top of the second placement frame 49 are all V-shaped. The guide shaft 47 is slidably connected inside the support frame 43, which facilitates the fixing of shaft bodies 5 of different sizes through the V-shape.

[0025] The inner top of the first placement bracket 44, the inner top of the second placement bracket 49, and the inner side of the clamping plate 46 are all in contact with the outer periphery of the shaft body 5, which facilitates the fixing of the shaft body 5 by the first placement bracket 44 and the clamping plate 46. The second placement bracket 49 has an extension function to meet the support of shaft bodies of different lengths.

[0026] In actual operation, when this device is used, when the self-lubricating lathe shaft needs to be processed and the excess metal at both ends needs to be cut off, the shaft body 5 is first placed inside the top of the first placement frame 44 located on the left and right sides of the top of the moving table 42 to ensure the initial stability of the shaft body 5. If the shaft body 5 is too long, the second placement frame 49 can further support the bottom left side of the shaft body 5 to ensure balance and stability during placement. At this point, the clamping plate 46 can be moved by the third hydraulic cylinder 45. When the clamping plate 46 moves, it will drive the guide shaft 47 to slide inside the support frame 43, so that the inner side of the clamping plate 46 and the outer side of the shaft body 5 come into contact with each other, forming a two-way fixation, which can ensure the stability of the shaft body 5 during the cutting work and avoid damage such as burrs and cracks at the cutting part due to the displacement of the shaft body 5. After the fixation is completed, the right end of the shaft body 5 that needs to be cut is located behind the cutting blade 394, waiting for the cutting work to be carried out. The first hydraulic cylinder 33 drives the movable seat 35 and the load-bearing frame 36 to move to the rear. When the movable seat 35 moves, it will slide around the guide rod 34, which will drive the cutting blade 394 to move to the rear. During the movement, the servo motor 391 drives the rotating rod 393, the positioning plate 392, the cutting blade 394 and the fixed plate 396 to rotate. When the cutting blade 394 contacts the right end of the shaft body 5, the cutting work can be performed. The protective cover 32 covers the first hydraulic cylinder 33 to prevent metal falling during the cutting process from affecting the first hydraulic cylinder 33. When the load-bearing frame 36 moves, it will drive the support roller 38 to rotate on the top of the fixed seat 31 through the protective frame 37. Under the action of the support roller 38, the movable seat 35 and the load-bearing frame 36 can be supported to ensure the stability of the cutting blade 394. The cutting blade 394 slides around the rotating rod 393, and its right side is in contact with the left side of the positioning plate 392. After installation, the limiting bracket 395 can be inserted into the cutting blade 394 and the positioning plate 392. Finally, the fixing plate 396 is threaded to the outer side of the left end of the rotating rod 393, so that the right side of the fixing plate 396 is in contact with the left side of the limiting bracket 395, which can fix the cutting blade 394. Conversely, disassembly can be performed, which improves the efficiency of installation and disassembly. When the cutting blade 394 is worn and breaks, it can be easily replaced. The operation is convenient. When it is necessary to cut the other end of the shaft body 5, the two ends can be swapped by the staff. When using this device, the diameter of both ends of the shaft body 5 being cut cannot exceed the radius of the cutting blade 394. At the same time, all the first hydraulic cylinders 33, the second hydraulic cylinders 41, the third hydraulic cylinders 45, and the servo motor 391 need to be connected to the same PLC controller near the device to ensure coordinated and automated operation of the equipment. The PLC controller is existing technology, and those skilled in the art are well aware of its operation method, so it will not be described in detail here.
