Description

Technical Field

[0001] The utility model relates to the technical field of pipe cutting, in particular to a round pipe aligning positioning device. Background Art

[0002] At construction sites, round tubes of various materials play a key role, covering infrastructure construction, industrial facilities, building construction, environmental protection and new energy, etc. In these fields, round tubes must be processed, and cutting, welding and other operations are required during the processing.

[0003] The direction of the pipeline is complex, so there will be pipelines of various shapes. When aligning and connecting two round tubes, the shapes of the cuts of the two round tubes are usually very different, which requires cutting another round tube to match the other round tube. These operations put forward high requirements on the positioning accuracy of the round tubes, and also directly affect the quality and efficiency of processing. In the past, in the assembly production process, skilled workers first roughly marked the round tubes to be cut according to the measured round tube cuts, and then cut the round tubes along the marked lines. However, this method is inefficient and not very accurate. For projects with small engineering volume and the need for efficient operation and precision control, there is a lack of efficient, simple and easy-to-operate positioning devices to assist workers in marking. Utility Model Content

[0004] In order to solve the above problems of the prior art, the utility model provides a round pipe alignment positioning device, which can mark another pipe according to the shape of the pipe cutout, thereby improving the accuracy of the round pipe fit after cutting.

Then the track frame is rotated to move the guide rod along the round tube cut, and the marking head marks the outer wall of the other round tube. This method improves the work efficiency of workers by using the rod linkage principle. At the same time, while ensuring the construction period, it can also ensure the one-time pass rate of the round tube after cutting, saving material waste caused by cutting errors and ensuring construction quality.

[0009] Preferably, the guide rod is fixedly connected to the head end of the spring, and the tail end of the spring is fixedly connected to the support plate.

[0010] With the above structural design, when in use, the spring is in a stretched state, so that the guide rod is closely attached to the cutout of the round tube to avoid dislocation.

[0011] Preferably, the marking rod is slidably connected to the linkage rod, a positioning bolt is passed through the marking rod, and a plurality of positioning holes matching the positioning bolts are provided on the linkage rod.

[0012] The above structural design makes it easy to adjust the guide rod and the marking rod according to the relative distance between the round tubes to adapt to the relative distance between the round tubes.

[0014] The above structural design enables the marking rod to contact the outer wall of the circular tube.

[0015] Preferably, the buckle assembly includes an arc-shaped rod fixedly connected to the lower end of the interference rod.

[0016] The above structural design ensures that the central axes of the two round tubes are aligned, thereby ensuring the accuracy of the marking.

[0017] Preferably, the buckle assembly includes relatively arranged arc-shaped clamping rods, a fixing plate fixedly connected to the end of the arc-shaped clamping rods, a fastening bolt passed through the fixing plate, and a roller rotatably connected to the inner side wall of the arc-shaped clamping rods, and the arc-shaped clamping rods are fixedly connected to the lower end of the resistance rods.

[0018] The above structural design can prevent the device from being separated from the round tube and causing misalignment of the mark.

[0019] Preferably, a threaded cylinder is fixedly connected to the supporting crossbeam, and the upper end of the abutment rod is connected to the threaded cylinder via threads.

[0020] With the above structural design, the buckle assembly is replaced to adapt to more round tubes.

[0028] Embodiment 1:

[0029] See also Figure 1 , Figure 2 , Figure 3 The utility model provides a technical solution: a circular tube alignment positioning device, comprising a track frame 1, a guide rod 2 slidably connected to the track frame 1, a linkage rod 3 fixedly connected to the guide rod 2, a marking rod 4 fixedly connected to the linkage rod 3, and a marking head 41 fixedly connected to the lower end of the marking rod 4, wherein the axial direction of the linkage rod 3 is perpendicular to the axial direction of the guide rod 2, and the lower end of the guide rod 2 is cut to form an inwardly concave arc structure; a resistance rod 5 is fixedly connected to the track frame 1, a pair of resistance rods 5 are fixedly connected to the track frame 1, the resistance rods 5 are respectively arranged at both ends of the track frame 1, and a buckle assembly for connecting the circular tube is arranged on the resistance rod 5.

[0030] The track frame 1 includes relatively arranged supporting beams 11, supporting plates 12 fixedly connected to the ends of the supporting beams 11, and slide grooves 13 provided on the supporting beams 11, wherein the slide grooves 13 match the guide rods 2, and the supporting beams 11 are fixedly connected to the resistance rods 5, which are respectively arranged at both ends of the supporting beams 11.

[0031] The guide rod 2 is fixedly connected to the head end of the spring 6, and the tail end of the spring 6 is fixedly connected to the support plate 12. The upper and lower ends of the guide rod 2 are fixedly connected to the card plate, and a support beam 11 is sandwiched between the card plates to prevent the guide rod from deviating from the track frame.

[0032] The marking rod 4 is slidably connected to the linkage rod 3 , a positioning bolt 31 is passed through the marking rod 4 , and a plurality of positioning holes matching the positioning bolts are provided on the linkage rod 3 .

[0033] The marking head 41 is fixedly connected to the lower end of the sleeve 42, and the sleeve 42 is inserted into the marking rod 4. A second spring 43 is arranged inside the sleeve 42, and the upper end of the second spring 43 is fixedly connected to the lower surface of the marking rod 4, and the lower end of the second spring 43 is fixedly connected to the marking head 41.

[0034] The buckle assembly includes an arc rod 71 fixedly connected to the lower end of the abutment rod 5. The arc rod 71 has low rigidity and certain elasticity, and can rotate and move along the round tube. During the rotation process, it can drive the guide rod 2 to move along the round tube mouth.

[0035] The support beam 11 is fixedly connected to a threaded barrel 51 , and the upper end of the abutment rod 51 is connected to the threaded barrel 51 via threads.

[0036] When the device is used, the first step is to determine the positions of the two round tubes to be cut, and then adjust the relative positions of the guide rod 2 and the marking rod 4 according to the cutting positions of the two round tubes to ensure that the guide rod 2 can align with the cut of the round tube.

[0037] The second step is to clamp the left end arc rod 71 on the round tube to be measured, and the right end arc rod 71 on the round tube to be cut. At the same time, align the guide rod 2 with the edge cut of the round tube to be measured, and ensure that the marking head 41 is placed on the round tube to be cut. It should be noted that the position of the left end arc rod 71 should be a little further to the left, so that the spring 6 is in a stretched state, and the guide rod 2 is close to the round tube cut to avoid misalignment.

[0038] The third step is to push and rotate the track frame 1, and keep the spring 7 in a stretched state during the rotation. By pushing the track frame 1 to rotate, the guide rod 2 moves along the cut of the round tube to be measured, and the marking rod 4 is driven to move by the linkage rod 3, so that the marking head 41 marks the cutting line on the round tube to be cut. After rotating the track frame 1 for one circle, the round tube to be cut is cut along the marked cutting line, and a cut that accurately matches the cut of the round tube to be measured can be obtained.

[0039] Embodiment 2:

[0040] like Figure 3As shown, the second embodiment is modified relative to the first embodiment, the buckle assembly includes an arc-shaped clamping rod 81 arranged oppositely, a fixing plate 82 fixedly connected to the end of the arc-shaped clamping rod 81, a fastening bolt 83 passing through the fixing plate 82, and a roller 85 rotatably connected to the inner wall of the arc-shaped clamping rod 81, a plurality of rollers 85 are provided, arranged along the circumference of the arc-shaped clamping rod 81, and the arc-shaped clamping rod 81 is fixedly connected to the lower end of the abutting rod 5. Other parts are in accordance with the first embodiment.

[0041] When the device is used, the first step is to determine the positions of the two round tubes to be cut, and then adjust the relative positions of the guide rod 2 and the marking rod 4 according to the cutting positions of the two round tubes to ensure that the guide rod 2 can align with the cut of the round tube.

[0042] The second step is to clamp the left end arc clamping rod 81 on the round tube to be measured, and use the fastening bolt 83 to connect the arc clamping rod 81, so that the arc clamping rod 81 holds the round tube tightly, and the right end arc clamping rod 81 is clamped on the round tube to be cut. At the same time, align the guide rod 2 with the edge cut of the round tube to be measured, and ensure that the marking head 41 is placed on the round tube to be cut. It should be noted that the position of the left end arc rod 71 should be a little further to the left, so that the spring 6 is in a stretched state, and the guide rod 2 is close to the round tube cut to avoid misalignment.

[0043] The third step is to push and rotate the track frame 1. Due to the existence of the roller 85, the arc-shaped clamping rod 81 can rotate, and the spring 7 is always kept in a stretched state during the rotation. By pushing the track frame 1 to rotate, the guide rod 2 moves along the cut of the round tube to be measured, and the marking rod 4 is driven to move by the linkage rod 3, so that the marking head 41 marks the line to be cut on the round tube to be cut. After rotating the track frame 1 for one circle, the round tube to be cut is cut along the marked cutting line, and a cut that accurately matches the cut of the round tube to be measured can be obtained.
