[0022] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0024] In some embodiments, see Figure 1 The present invention provides a pipe measuring welding machine, including a fixing member 1, on which a pair of mutually meshing gears 2 are rotatably connected, and the two gears 2 are fixedly connected to connecting rods 3, and one end of the connecting rod 3 away from the gears 2 is provided with a mounting member 4 for mounting the pipe, and the two connecting rods 3 are symmetrically arranged with each other, and the fixing member 1 is provided with a dial 5 for measuring the angle between the two connecting rods 3, and the fixing member 1 is also provided with a marking portion, and the marking portion is located at the angle bisector of the angle.

[0025] During use, first adjust the angle between the connecting rods 3 according to the welding angle of the pipe, and then adjust the angle between the connecting rods 3 according to the dial 5. Since the connecting rods 3 are meshed with each other through the gear 2 and the two are symmetrical to each other, the angle bisector between the two is always consistent and will not change, so that the marked part can always be located on the angle bisector of the angle.

[0026] After adjusting the angle, the operator can first fix a pipe through one of the mounting parts 4, and then use the marking part to mark the pipe. After marking, remove the first pipe, connect the second pipe to another mounting part 4, and then use the marking part to mark the pipe. After marking, remove the second pipe. At this time, the first pipe and the second pipe have been marked, and the operator can cut according to the marking. After cutting is completed, the first pipe and the second pipe can be fixed on the mounting part 4 respectively. At this time, the incisions of the first pipe and the second pipe are in a matching state, and the operator can perform welding.

[0027] In this embodiment, by setting a connecting rod 3 meshing with the gear 2, the bisector of the angle of the connecting rod 3 can be effectively determined, thereby facilitating the marking of the pipe through the marking portion. Combined with the fixing effect of the mounting member 4, rapid marking, cutting and welding of the pipe can be achieved, greatly improving work efficiency.

[0028] In some embodiments, see Figure 2 The marking part includes a marking rod 6, the bisector of the angle and the plane where the marking rod 6 is located are perpendicular to the plane where the two connecting rods 3 are located, and a plurality of through holes are provided on the marking rod 6, and a marking pen 7 is movably inserted in each of the through holes.

[0029] In the above embodiment, the marking part is further disclosed. In the specific implementation process, the pipe also has an irregular structure. The traditional marking equipment is generally complex in structure or cannot complete the marking operation. In view of the above problem, a plurality of through holes are set on the connecting rod 3, and the marking pen 7 can move relative to the through holes. When the marking pen 7 is located in front of the irregular pipe, the marking pen 7 can be pressed in turn, and the head of the marking pen 7 will contact the surface of the pipe accordingly. The pressing force is based on the standard that each marking pen 7 cannot move forward, thereby leaving a dotted line on the surface of the pipe. According to the dotted line, the operator can complete the cutting of the pipe.

[0030] In some embodiments, see Figure 1 The marking rod 6 and the fixing member 1 are connected via a retractable supporting rod 8 .

[0031] In the above embodiment, the structure of the marking part is further disclosed. By providing a retractable support rod 8, when facing pipes of different sizes, the distance between the marking pen 7 and the surface of the pipe can be adjusted accordingly through the support rod 8, thereby ensuring that the marking pen 7 can work normally.

[0032] In some embodiments, see Figure 1 , the marking rod 6 has a telescopic function.

[0033] In the above embodiment, due to the different welding angles between the pipes, the position of the marking pen 7 at the connection of the pipes will also change to a certain extent. Therefore, the position of the connection between the marking pen 7 and the pipe can be adjusted by extending and retracting the marking rod 6, thereby ensuring that the marking pen 7 can perform normal marking work.

[0034] In some embodiments, see Figure 3 The marking pen 7 comprises a hollow sleeve 9, which is movably clamped in the through hole, and a sponge core 10 is provided in the middle of the sleeve 9.

[0035] In the above embodiment, the structure of the marking pen 7 is further disclosed. The sleeve 9 and the through hole can be connected in a conventional manner. For example, a limit block can be provided on the outer wall of the sleeve 9 to ensure that the sleeve 9 does not fall off when sliding in the through hole. The sponge core 10 can be filled with colored pigments such as ink, and the end of the sponge core 10 can also slightly extend out of the sleeve 9, so as to facilitate leaving a marking mark on the pipe.

[0036] In some embodiments, see Figure 3 A filling rod 11 is provided at one end of the sleeve 9 close to the connecting rod 3. The filling rod 11 is parallel to the marking rod 6 and forms an inverted T-shaped structure with the sleeve 9. An open groove 12 connected to the inside of the sleeve 9 is opened at one end of the filling rod 11 close to the connecting rod 3.

[0037] In the above embodiment, the structure of the marking pen 7 is further optimized. By providing the filling rod 11, the dot-shaped ink originally flowing out of the sleeve 9 can be changed into a line-shaped one, so that the marking line is thinner and clearer, and the continuity of the marking line is also better.

[0038] In some embodiments, see Figure 1 The scale plate 5 includes a first scale 13 and a second scale 14. The starting points of the first scale 13 and the second scale 14 are both located on the angular bisector of the included angle and extend to both sides with the starting point as the center. The value of the second scale 14 is twice the value of the first scale 13.

[0039] In the above embodiment, the structure of the dial 5 is further optimized. In the present disclosure, under the meshing action of the gear 2, the rotation between the connecting rods 3 is symmetrical. Therefore, the starting point of the dial 5 can be set in the middle, that is, on the bisector of the angle, and the remaining scales can extend to both sides with the starting point as the center, and are divided into a first scale 13 and a second scale 14. The angle between the connecting rod 3 and the bisector of the angle can be measured through the first scale 13, which is convenient for calculating the marking angle of a single pipe during the marking process. Doubling the value of the second scale 14 facilitates the calculation of the angle between the two pipes.

[0040] In some embodiments, see Figure 1 The mounting member 4 includes a plurality of connectors of different types, and the plurality of connectors are detachably connected to the connecting rod 3 .

[0041] In the above embodiment, the structure of the mounting member 4 is further disclosed. Since the pipes have different sizes and structures, various types of connectors can be provided, and the connection with the connecting rod 3 can be detachable, thereby improving the scope of application of the structure, thereby facilitating operation by the staff and improving work efficiency.

[0042] In some embodiments, the connector is a U-shaped plate and bolts disposed on the U-shaped plate and used to fasten the pipe.

[0043] In the above embodiments, the structure of the connector is specifically disclosed. When the pipe is non-metallic, the pipe can be clamped by a U-shaped plate and then fastened by bolts.

[0044] In some embodiments, the connector is an L-shaped electromagnetic adsorption probe, and an electromagnetic adsorption device matching the electromagnetic adsorption probe is disposed in the connecting rod 3 .

[0045] In the above embodiment, another specific disclosure is made on the structure of the connector. When the pipe is made of metal, the electromagnetic adsorption device can be turned on so that the electromagnetic adsorption probe can adsorb the pipe, which can reduce the extrusion damage to the metal pipe caused by fixation and improve work efficiency.

[0046] It should be noted that, in this article, relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0047] The above description is only a specific embodiment of the present disclosure, so that those skilled in the art can understand or implement the present disclosure. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present disclosure.
