[0032] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0033] like Figure 2 As shown, at least one embodiment provides a PIR pipe notch processing equipment, including: an equipment frame 5, on which two limit plates 51 are spaced apart, the two limit plates 51 are vertically arranged with the equipment frame 5, and the two limit plates 51 are parallel to each other. A central axis 2 is rotatably arranged between the two limit plates 51, and the central axis is suitable for mounting a pipe body 1. Either end of the central axis 2 is suitable for connecting an electric actuator, such as a motor, and the central axis 2 can be driven by the electric actuator to drive the pipe body 1 to rotate. Figure 1 As shown, the pipe body 1 is preferably a semi-cylindrical pipe fitting, specifically, a PIR pipe, which is commonly used for cold-keeping pipes. Two PIR pipes are placed on the central axis 2 and spliced ​​to form a complete cylinder. The ends of the pipe body 1 have annular grooves, and the inner side of the annular grooves has matching protrusions 11, which are used to assist in matching and positioning when multiple pipe bodies 1 are connected. On the other hand, in order to process the outer contour of the end of the pipe body 1 so that the end of the pipe body 1 forms a notch for matching, in some embodiments, a support frame 52 is further provided on the limit plate 51, and a driving motor 53 is provided on the support frame 52. A processing knife 54 is installed at the movable end of the driving motor 53. After the pipe body 1 is installed, the processing knife 54 can be driven to rotate by the driving motor 53, so that the processing knife 54 processes the pipe body 1.

[0034] It should be noted that if the parallelism error between the tube body 1 and the shaft center hole is large, when the tube body 1 is installed on the center shaft 2, the heights of both ends may be uneven, and during the tool processing process, the notches at both ends of the PIR tube cannot be symmetrical. In order to solve the above problem, Figure 2As shown, in some embodiments, two positioning components 3 are also installed on the central axis 2, and the two positioning components 3 are both sleeved on the central axis 2, and the two positioning components 3 are respectively located on both sides of the pipe body 1. The positioning component 3 is slidably provided with a plurality of positioning blocks 4 toward one side of the pipe body 1, and each of the positioning blocks 4 is arranged around the central axis 2. Through the above arrangement, when the pipe body 1 is installed, the two positioning components 3 are respectively moved close to the pipe body 1 from both sides until each of the positioning blocks 4 on the two positioning components 3 is engaged with the pipe body 1. At this time, the pipe body 1 is positioned by the positioning blocks 4, and the positions of the positioning blocks 4 on both sides are aligned, which can ensure that the two ends of the pipe body 1 remain aligned. Then, when the processing knife 54 is used for processing, symmetrical notches can be processed at both ends of the pipe body 1 to meet the assembly requirements in the subsequent actual use process.

[0035] In order to achieve the effect of keeping the two ends of the tube body 1 aligned after the positioning blocks 4 are clamped with the tube body 1, in some embodiments, the distances between the positioning blocks 4 and the central axis 2 are equal. Through the above arrangement, it can be ensured that after the positioning blocks 4 clamp and position the tube body 1, the distances between the outer walls of the tube bodies 1 and the central axis 2 are equal, that is, the two ends of the tube body 1 are aligned.

[0036] like Figure 3 As shown, in some embodiments, the positioning assembly 3 includes a positioning disk 31 and an adjusting member 32 which are separately arranged, and the positioning disk 31 is located on the side of the adjusting member 32 facing the pipe body 1. Each of the positioning blocks 4 is slidably arranged on the positioning disk 31. The adjusting member 32 is detachably fixed to the central axis 2, and the adjusting member 32 abuts against each of the positioning blocks 4. Through the above arrangement, after the pipe body 1 is installed, the adjusting member 32 can be brought close to the positioning disk 31, and the adjusting member 32 pushes each of the positioning blocks 4 to open radially outward along the positioning disk 31, so that the positioning blocks 4 are opened to the opening and closing degree of the size of the matching protrusion 11 on the adapter pipe body 1, thereby making the positioning blocks 4 clamp the pipe body 1. In order to ensure that the positioning blocks 4 can reliably clamp the surrounding of the pipe body 1, each of the positioning blocks 4 is evenly distributed along the circumference of the positioning disk 31.

[0037] In order to achieve the effect that the positioning block 4 can slide open or close along the radial direction of the positioning plate 31, in some embodiments, such as Figure 4 As shown, the positioning plate 31 is provided with a plurality of slide grooves 311 along the circumferential direction, and the slide grooves 311 extend along the radial direction of the positioning plate 31, and one slider corresponds to one positioning block 4. Specifically, the positioning block 4 has a slider on one side facing the slide groove 311, and the slider cooperates with the slide groove 311 so that the positioning block 4 can slide in the slide groove 311.

[0038] In order to achieve the effect of driving each positioning block 4 to open outward when the adjusting member 32 is close to the positioning plate 31, in some embodiments, as Figure 3 As shown, the end of the positioning block 4 facing the adjusting member 32 is provided with a seesaw 41, and the side of the adjusting member 32 facing the positioning block 4 is provided with a guide slope 321. The seesaw 41 corresponds to the guide slope 321. Through the above arrangement, when the adjusting member 32 approaches the positioning plate 31, the adjusting member 32 pushes the seesaw 41 through the guide slope 321 to generate a radial outward force on the positioning block 4 along the positioning plate 31, so that the positioning block 4 slides outward along the slide groove 311.

[0039] In order to enable the positioning block 4 to be reset after opening, an adjustment spring 33 is provided in the slide slot 311, and the two ends of the adjustment spring 33 are respectively connected to the bottom wall of the slide slot 311 and the positioning block 4. Through the above arrangement, after the adjustment member 32 drives the positioning block 4 to open, the adjustment spring 33 is stretched, and when the adjustment member 32 is separated from the positioning block 4, the adjustment spring 33 can pull the positioning block 4 to reset.

[0040] In order to achieve the effect of the detachable fixing arrangement of the adjusting member 32 and the central shaft 2, in some embodiments, the adjusting member 32 is threadedly connected to the central shaft 2. Through the above arrangement, after the adjusting member 32 pushes each positioning block 4 open, the position relative to the central shaft 2 can be kept fixed by the thread, thereby ensuring that the positioning block 4 is continuously pushed, so that the positioning block 4 maintains an unchanged opening and closing degree, so as to continuously clamp the positioning tube body 1.

The specific structure, working principle and possible control method and spatial layout method of these technical features can be selected by conventional methods in the field and should not be regarded as the invention point of this utility model patent.
