[0037] Example 1

[0038] like Figures 1-4 As shown, this utility model provides a technical solution: a pipe processing positioning mechanism, including a clamping platform 1, with clamping cylinders 2 corresponding to each other on both sides of the top of the clamping platform 1, and clamping parts 3 corresponding to the output ends of the two clamping cylinders 2 and slidably connected to the clamping platform 1. One clamping part 3 is higher than the other clamping part 3. The clamping part 3 is used to clamp the pipe on both sides. Rubber pads are bonded according to the pipe material. A positioning plate 4 is installed on the side clamping part 3 facing the lower clamping part 3. The positioning plate 4 overlaps and slides on the top of the lower clamping part 3. At the same time, a pressing cylinder 5 is installed on the top of the positioning plate 4 away from the overlapping end of the positioning plate 4. A pressure plate 6 is installed on the output end of the pressing cylinder 5. The pressure plate 6 presses down to cooperate with the clamping platform to position the pipe up and down.

[0039] The clamping component 3 is provided with arc support blocks 7 on the corresponding side of the clamping platform 1, and the positions of the arc support blocks 7 on both sides are staggered.

[0040] It should be noted that the clamping platform 1 is installed on the pipe processing equipment.

[0041] Example 2

[0042] like Figures 1-4 As shown, the clamping platform 1 has several guide grooves 11 extending through the bottom along its length. The clamping member 3 is divided into upper and lower ends and connected by guide blocks 8 passing through the guide grooves 11. The upper and lower ends of the clamping member 3 are connected by guide blocks 8. When the clamping cylinder 2 pushes the clamping member 3 to move, the guide blocks 8 at the upper and lower ends of the clamping member 3 slide along the guide grooves 11 at the bottom of the clamping platform 1, ensuring that the movement path of the clamping member 3 is accurate and stable.

[0043] The bottom of the clamping platform 1 is provided with connecting frames 12 at both ends, and a guide rod 13 is provided between the two connecting frames 12. The clamping member 3 is provided with a guide hole 31. The clamping member 3 is sleeved on the guide rod 13 through the guide hole 31, which enhances the stability of the clamping member 3 during movement and reduces shaking and error.

[0044] The positioning plate 4 is slidably connected to the sliding groove 32 opened at the top of the lower side clamping member 3.

[0045] To ensure that the pressing plate 6 is pressed stably, the bottom of the pressing plate 6 is in a circular arc structure, and an arc groove 61 is formed in the bottom, and a positioning pad 62 is bonded in the arc groove 61,

[0046] The two side arc supporting blocks 7 correspond to the arc structure of the surface.

[0047] The output end of the clamping cylinder 2 penetrates the guide seat 14 at the top end of the clamping platform 1, and the guide seat 14 provides telescopic guidance for the output end of the clamping cylinder 2.

[0048] The working process of the utility model is as follows: when the pipe machining positioning mechanism is used, first, the pipe to be machined is placed on the clamping platform 1, and the two clamping cylinders 2 are started, and the output ends of the two clamping cylinders 2 will push the clamping pieces 3 to move along the guide grooves 11 and the guide rods 13 towards the pipe, and since one clamping piece 3 is higher than the other clamping piece 3, the positioning plate 4 on the high clamping piece 3 will first contact the low clamping piece 3 and slide along the sliding groove 32, and with the movement of the clamping piece 3, the arc supporting blocks 7 will contact the side surface of the pipe, and since the two arc supporting blocks 7 are staggered and adapt to the length and shape of the pipe, the pipe is preliminarily supported, and when the clamping piece 3 preliminarily clamps the pipe, the down-pressing cylinder 5 is started, and the output end of the down-pressing cylinder 5 will push the pressing plate 6 to move downwards until the circular arc structure at the bottom of the pressing plate 6 and the positioning pad 62 in the arc groove 61 tightly fit the surface of the pipe, so that the pipe is stably clamped on the clamping platform 1, and after the pipe is stably clamped, the pipe machining equipment (such as a cutting machine, a punching machine, etc.) can start machining operation. Since the pipe is stably clamped and fixed, the machining process will be more accurate and safe, and the whole use is completed.

[0049] Through the above working process, the pipe machining positioning mechanism provided by the utility model can realize quick and stable clamping and positioning of pipes of different sizes, and provides a strong guarantee for accurate machining of the pipes.

[0050] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
