A movable linear module 202 is slidably mounted on the fixed linear module 201. A sliding mounting seat 203 is slidably mounted on the top side of the movable linear module 202. A mounting bracket 204 is fixedly mounted on the lower section of the sliding mounting seat 203. 4. Two U-shaped movable frames 300 are slidably installed on the side. Positioning sleeves 301 are fixedly installed on each of the two U-shaped movable frames 300. A round tube 104 is placed between the two positioning sleeves 301. The two positioning sleeves 301 that are adapted to the specifications of the round tube 104 are used to clamp and position it in a covering manner, thereby ensuring the stable processing of the round tube 104. At the same time, the fixed linear module 201, the movable linear module 202, and the sliding mounting seat 203 work together to control the movement of the round tube 104, thereby facilitating the device to cut out a suitable shape inside the round tube 104 and facilitating the processing and production of the round tube 104.
[0022] In an optional embodiment: the mounting bracket 204 has a limiting groove 302 on its side, and two limiting sliders 303 are slidably installed in the limiting groove 302. The two limiting sliders 303 are respectively fixedly installed on the U-shaped movable frame 300.
[0023] It should be noted that the movement of the U-shaped movable frame 300 is restricted by the limiting slide groove 302 and the limiting slider 303, and can only move within a fixed range.
[0024] In an optional embodiment: a hydraulic telescopic rod 205 is fixedly installed on the sliding mounting base 203, an L-shaped drive plate 206 is fixedly installed at the output end of the hydraulic telescopic rod 205, and a drive rod 207 is rotatably installed between the L-shaped drive plate 206 and the U-shaped movable frame 300.
[0025] It should be noted that the output end of the hydraulic telescopic rod 205 drives the L-shaped drive plate 206 to descend. The movable L-shaped drive plate 206 drives one end of the drive rod 207 to rotate through the transmission shaft 208, while the other end of the drive rod 207 also drives the U-shaped movable frame 300 to slide on the mounting frame 204 through the transmission shaft 208.
[0026] In an optional embodiment: both ends of the drive rod 207 are rotatably mounted with drive shafts 208, and the two drive shafts 208 are respectively fixedly mounted on the L-shaped drive plate 206 and the U-shaped movable frame 300.
[0027] In an optional embodiment, a filter screen 400 is fixedly installed inside the processing chamber 200.
[0028] In an optional embodiment: a cutting fluid pump 401 is fixedly installed inside the filter screen 400, and a cutting fluid delivery pipe 402 is fixedly installed at the output end of the cutting fluid pump 401. The cutting fluid delivery pipe 402 is adapted to the round pipe fitting 104.
[0029] It should be noted that during the cutting process, the cutting fluid pump 401 is started, and the clean cutting fluid filtered out of the filter screen 400 is sprayed onto the round pipe 104 through the cutting fluid delivery pipe 402, which plays a role in protecting the workpiece and the molybdenum wire, and the cutting fluid is recycled.
[0030] In an optional embodiment: the positioning sleeve 301 has a U-shaped structure, and two positioning sleeves 301 are sleeved on the round tube 104. It should be noted that the round tube 104 is fixed between the movable molybdenum wire mounting bracket 102 and the fixed molybdenum wire mounting bracket 103, and the positioning sleeves 301 are used to clamp and fix the round tube 104 on both sides.
[0031] Working principle:
[0032] When using this device, firstly, the round tube 104 needs to be fixed between the movable molybdenum wire mounting bracket 102 and the fixed molybdenum wire mounting bracket 103. Positioning sleeves 301 are used to clamp and fix the round tube 104 on both sides. Then, the hydraulic telescopic rod 205 is activated. The output end of the hydraulic telescopic rod 205 drives the L-shaped drive plate 206 to descend. The movable L-shaped drive plate 206 drives one end of the drive rod 207 to rotate via the transmission shaft 208. The other end of the drive rod 207 also drives the U-shaped movable frame 300 to slide on the mounting bracket 204 via the transmission shaft 208. The sliding U-shaped movable frame 300 drives the positioning sleeves 301 to move closer together, causing the positioning sleeves 301 to clamp the round tube 104. The movement of the U-shaped movable frame 300 is restricted by the limiting groove 302 and the limiting slider 303, and can only move within a fixed range. Then... The molybdenum wire on the device is arranged by passing through the molybdenum wire roller 101, the movable molybdenum wire mounting bracket 102, the fixed molybdenum wire mounting bracket 103, and the round tube 104 for easy equipment layout. The sliding mounting seat 203 can move on the movable linear module 202, which can move on the fixed linear module 201. The fixed linear module 201, the movable linear module 202, and the sliding mounting seat 203 work together to control the movement of the round tube 104, thereby facilitating the device to cut a suitable shape inside the round tube 104 and facilitating the processing and production of the round tube 104. During the cutting process, the cutting fluid pump 401 is started, and the clean cutting fluid filtered in the filter screen 400 is sprayed onto the round tube 104 through the cutting fluid delivery pipe 402 to protect the workpiece and the molybdenum wire, and the cutting fluid is recycled.
[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
