[0002] At present, vertical milling, plasma cutting, wire cutting or flame cutting are used to process the intersecting curved surface of pipe heads. Among these processing methods, milling, plasma cutting and wire cutting have low efficiency and high cost, while flame cutting has poor precision and cannot meet the requirements of batch processing of the intersecting curved surface of pipe heads.

[0003] After retrieval, the Chinese patent publication number: CN205673922U discloses a processing tool for intersecting curved surfaces. By setting a number of positioning grooves, workpieces can be clamped individually. Therefore, the processing of intersecting curved surfaces of workpieces with different diameters and different lengths can be realized, and one-time clamping and multi-piece processing are achieved, changing the problems of low efficiency and high cost of traditional milling and poor precision of flame cutting.

[0004] However, the above-mentioned processing tool has certain defects in the use process. For example, when processing multiple round tubes with different diameters in one-time clamping, the diameters of adjacent round tubes are different, resulting in that the pressing block cannot fit the surface of the round tube with a smaller diameter during clamping, and displacement or vibration occurs during processing, affecting the precision of the intersecting curved surface. Therefore, a processing device for the intersecting curved surface of round tubes is proposed to solve the above problems. Summary of the Utility Model

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] Refer to Figure 1 - Figure 2 As shown in the figure, an embodiment provided by the present utility model: A processing device for a circular tube intersecting curved surface includes a mounting plate 1. Processing holes 2 are provided on the surface of the mounting plate 1. The processing holes 2 are located at the center of the surface of the mounting plate 1. Multiple groups of positioning grooves 3 are provided on the surface of the mounting plate 1. The multiple groups of positioning grooves 3 are arranged in an array with the center of the circle of the processing hole 2 as the rotation center. The cross-sectional shape of the positioning groove 3 is set as a T shape. The inner walls of both sides of the positioning groove 3 close to the surface of the mounting plate 1 are set to be inclined. Multiple groups of positioning grooves 3 can realize the processing of multiple workpieces by installing multiple moving seats 31. The T-shaped positioning groove 3 provides vertical direction limitation for the moving seat 31 to ensure the stability of the movement of the moving seat 31. The inclined inner wall of the positioning groove 3 is used to provide a positioning function for the circular tube placed on the surface of the mounting plate 1. A moving seat 31 is slidably connected inside the positioning groove 3. A through hole is provided on the surface of the moving seat 31, and a positioning bolt 32 is threadedly connected in the through hole. By adjusting the tightness of the positioning bolt 32, the position of the moving seat 31 can be controlled. A baffle 33 is fixedly connected to the surface of the moving seat 31. The baffle 33 is used to position the end of the circular tube.

[0029] Refer to Figure 1 、 Figure 3, a plurality of groups of thread posts 4 distributed in an array are fixedly connected to the surface of the mounting disk 1. An adjusting nut 5 is threadedly connected to the outer wall of the thread post 4, and a positioning assembly 6 is arranged on the outer wall of the thread post 4. The adjusting nut 5 and the thread post 4 are used to press the positioning assembly 6 against the surface of the circular tube. The positioning assembly 6 includes an arc-shaped plate 61. A notch 62 is formed on the side wall of the arc-shaped plate 61. The thread post 4 is inserted into the notch 62. The arc-shaped plate 61 serves as a support platform in the positioning assembly 6. The height of the arc-shaped plate 61 is limited by the adjusting nut 5. Two groups of symmetrically arranged through holes are formed on the surface of the arc-shaped plate 61, and a lead screw 63 is threadedly connected in the through holes. One end of the lead screw 63 is fixedly connected with a brake wheel 64, and the other end of the lead screw 63 is rotatably connected with a pressing block 65. A rubber pad 66 is fixedly connected to the inclined surface of the pressing block 65. The brake wheel 64 is used to drive the lead screw 63 to rotate. By rotating the lead screw 63, the pressing block 65 moves downward, so that the inclined surface of the pressing block 65 fits against the surface of the circular tube. The rubber pad 66 protects the surface of the circular tube to prevent wear caused by hard contact. Moreover, the two lead screws 63 can be adjusted to different heights simultaneously, so as to ensure the stability of circular tubes with different diameters during processing. A groove 67 is formed at the end of the arc-shaped plate 61. A guide rod 68 is slidably connected in the groove 67. The guide rod 68 is fixedly connected to the surface of the pressing block 65. The groove 67 and the guide rod 68 are used to guide the pressing block 65, so that the pressing block 65 will not rotate with the rotation of the lead screw 63 during the movement process.

[0030] Working principle: First, place the circular tube to be processed on the surface of the mounting disk 1. Due to the inclined inner wall of the positioning groove 3, the circular tube can be quickly and accurately positioned at a predetermined position. Subsequently, by adjusting the positioning bolt 32 installed on the moving seat 31 in the positioning groove 3, ensure that the end of the circular tube is in close contact with the baffle 33, so as to achieve precise positioning of the end of the circular tube.

[0031] Then, by adjusting the adjusting nut 5 installed on the thread post 4, press the positioning assembly 6 against the surface of the circular tube. The arc-shaped plate 61 serves as a support platform, and its height is limited by the adjusting nut 5 to ensure that the positioning assembly 6 is in close contact with the surface of the circular tube. At this time, by rotating the brake wheel 64, drive the lead screw 63 to rotate, so that the pressing block 65 moves downward. The inclined surface of the pressing block 65 fits against the surface of the circular tube, and the rubber pad 66 plays a buffering and protecting role to prevent wear caused by hard contact.

[0032] Since the two lead screws 63 can be adjusted to different heights, it is possible to adapt to circular tubes with different diameters for processing. The cooperation between the groove 67 and the guide rod 68 ensures that the pressing block 65 will not rotate with the rotation of the lead screw 63 during the movement process, thus ensuring the stability during the processing.

[0033] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
