Description

Technical Field

[0001] The utility model belongs to the field of end cap processing devices, in particular to a thin-wall end cap end face turning tool. Background Art

[0002] Thin-walled stainless steel equipment is often used in refining and chemical plants. In thin-walled stainless steel equipment, a head is used as the end of a sealed container for isolation. The interface of the thin-walled head is usually processed by turning the end face of the head. Currently, the turning process of the thin-walled head is mostly performed by fixing the thin-walled head with a lathe chuck. During the turning process, the spindle speed is relatively high. To ensure safe production, the head needs to be firmly fixed. The lathe chuck usually clamps the thin-walled head from the inside, which causes the lathe chuck to have a large supporting force on the thin-walled head, causing the thin-walled head to deform, affecting the subsequent turning process and the quality of the finished product, making the processing accuracy of the thin-walled head poor, and making it difficult to weld, install and use it later. During the processing, the chuck will affect the tool's cutting work on the end face of the head and it is difficult to correctly position the head. The operation is cumbersome and inconvenient, affecting work efficiency. Utility Model Content

[0018] In order to better understand the purpose, structure and function of the utility model, the thin-walled head end face turning tool of the utility model is further described in detail below in conjunction with the accompanying drawings.

[0019] like Figure 1-7 As shown, the utility model thin-walled head end face turning tool comprises a main body 1; a main body 1 is provided with a spindle box 2 on one side; a main body 1 is provided with a track 3 on one side of the spindle box 2; a tool holder 4 is slidably provided on the track 3; a cutting tool 5 is provided on the tool holder 4; a spindle 6 is provided extending outward from the spindle box 2; a support device 7 is fixedly provided at one end of the spindle box 2; the support device 7 comprises a main bracket 8; a rotating shaft 9 is rotatably provided in the middle of the main bracket 8; a rotating disk 10 is fixedly provided at one end of the rotating shaft 9 away from the spindle 6; a side of the main bracket 8 away from the spindle 6 is circumferentially provided, etc. Three slide rails 11 are provided; a slider 12 is slidably provided on the slide rail 11; a push rod 13 is rotatably provided at one end of the slider 12 close to the rotating shaft 9 and is rotatably connected to the turntable 10; an arc-shaped support plate 14 is fixedly provided on the slider 12, and a plurality of arc-shaped support plates 14 are combined into a circle; a connecting rod 15 is fixedly provided at one end of the rotating shaft 9 close to the main shaft 6; a cylinder 16 is provided on one side of the rotating shaft 9 of the main bracket 8; a cylinder head of the cylinder 16 and an end of the connecting rod 15 away from the rotating shaft 9 are rotatably connected; a positioning device 17 is fixedly provided at one end of the turntable 10 away from the rotating shaft 9.

[0020] Combination Figure 1-7As shown, during use, the thin-walled end cap is sleeved on the outside of the supporting device 7, so that the positioning end head 19 of the positioning device 17 fits the inner wall of the head of the thin-walled end cap, and the cylinder 16 is started. The cylinder head of the cylinder 16 pushes the connecting rod 15 to drive the rotating shaft 9 to rotate, and the rotating shaft 9 pushes the push rod 13, so that the push rod 13 pushes the slider 12 to slide on the slide rail 11, driving the multiple arc-shaped support plates 14 to expand outward, and the thin-walled end cap is tensioned and supported from the inside, and then the tool holder 4 is slid on the track 3, and the spindle 6 of the spindle box 2 is started to drive the thin-walled end cap to move. The wall head rotates at high speed, and then the cutting tool 5 is used to cut the end of the thin-walled head. The outwardly expanded arc support plate 14 is supported on the inner wall of the thin-walled head, which will not affect the cutting work on the end of the head. Multiple arc support plates 14 form a circular support from the inside of the thin-walled head. The arc support plate 14 has a large contact area with the inner wall of the thin-walled head, so that the overall force on the head is more uniform, which can effectively prevent the thin-walled head from being deformed due to excessive force at a single position, affecting the subsequent turning and welding.

[0021] The positioning device 17 includes a support column 18 fixedly connected to the turntable 10; a positioning end 19 is fixedly provided at one end of the support column 18 away from the turntable 10. In the process of installing the thin-walled head to the outside of the support device 7, the head is sleeved on the outside of the support device 7 so that the inner wall of the head of the head fits with the positioning end 19 of the positioning device 17, and then the cylinder 16 is started to open the multiple arc-shaped support plates 14 to fix the head. The installation positioning of the head is accurate, which prevents the fixed head from being skewed, making it difficult to perform normal turning work later, and the installation operation process is relatively convenient, thereby increasing work efficiency.

[0022] Combination Figure 6-7 As shown, the positioning end 19 can be set to different shapes such as arc surface, hemispherical, cone-top, concave, etc. according to the use requirements. When assembling the positioning device 17 of the present device, the positioning end 19 that fits the shape of the thin-walled head to be turned is set according to the shape of the thin-walled head to be turned, so that the positioning device 17 can be suitable for the positioning work of turning thin-walled heads of various shapes, and has a wide range of applications.
