The core purpose is to provide a high-quality interface for pipe welding, ensuring sufficient weld fusion, adequate strength, and avoiding welding defects such as porosity. When using a beveling machine to machine pipe end faces, if the pipe is not perpendicular or aligned with the beveling machine cutter head, quality problems such as cutter bar vibration, ripples on the bevel surface, and tilted bevels may occur during the machining process. These issues increase the difficulty of subsequent welding and lead to substandard weld quality.

The four corners of the fixed seat 1 are also provided with countersunk through holes, and the countersunk bolts are installed in the countersunk through holes and connected with the bolt holes on the cutter disc plane, so as to realize the detachable connection of the fixed seat on the cutter disc plane. After the installation of the countersunk bolts, the flatness of the plane around the T-shaped groove can be ensured, and interference caused by the disassembly and assembly of the positioning block can be avoided. The T-shaped groove 4 is provided with a jack hole 3 on one side or opposite sides of the solid structure, and the jack hole 3 is in communication with the lower part of the T-shaped groove 4. After the jack is installed in the jack hole 3, it can be jacked on the positioning block 2 in the T-shaped groove 4, so as to realize the detachable fixed connection of the positioning block 2 and the fixed seat 1.

[0021] Further, at least one end of the T-shaped groove 4 in the length direction is opened, so that the positioning block 2 can be slidably inserted into the T-shaped groove 4 from the opening.

[0022] The structure of the positioning block 2 is shown in Figure 5 , 6 As shown, the positioning block 2 is a T-shaped block as a whole, including a bottom plate 6 and a positioning plate 7 perpendicular to each other, and the bottom plate 6 and the positioning plate 7 are an integral structure or are fixed together by welding or other means. The positioning plate 7 is a rectangular plate, and one end of the positioning plate 7 away from the bottom plate 6 is a positioning end, and the end face of the positioning end is parallel to the bottom surface of the bottom plate 6.

[0027] Preferably, the bolt holes on the cutter disc plane 10 are arranged in groups, and one group of bolt holes is used to connect one fixing seat 1. For a pipe with a certain diameter, the corresponding tool setting assembly 100 is distributed on the same circumference of the cutter disc plane 10, and therefore a plurality of groups of bolt holes are distributed on the circumference. For pipes with different diameters, a plurality of groups of bolt holes are distributed at different positions along the radial direction of the cutter disc plane 10, so as to flexibly adjust the installation position of the tool setting assembly 100 on the cutter disc plane 10 according to the diameter of the pipe end face, and meet the positioning requirements of pipes with different diameters.

[0028] In this embodiment, three tool setting assemblies 100 are installed on the cutter disc plane 10 to form a tool setting device, and then the principle of three-point determination of a plane is used for positioning the pipe end face.

[0029] The use process of the pipe tool setting device will be described below with reference to FIGS. 1 to 4. Figure 7 、 8 The structure of the pipe tool setting device will be further described through the use process.

[0030] (1) The bolt hole position for installing the tool setting device on the cutter disc plane 10 is determined according to the diameter of the pipe end face 12 of the pipe 11, and three fixing seats 1 are installed on the cutter disc plane 10 in the circumferential direction through countersunk head bolts; (2) The bottom plate 6 of the positioning block 2 is inserted into the T-shaped slot 4 of the fixing seat 1, the position of the positioning block 2 is slightly adjusted, and then the jackscrew in the top screw hole 3 is tightened to press the end of the jackscrew against the side surface of the bottom plate 6 of the positioning block 2; (3) After the installation of the tool setting device on the cutter disc plane 10 is completed, the pipe end face beveling machine 9 is operated to move the cutter disc plane 10 towards the pipe 11 to be machined, or the pipe 11 to be machined is operated to move the pipe end face 12 towards the cutter disc plane 10, until the pipe end face 12 is in close contact with the end faces of the three positioning blocks 2, which indicates that the pipe is perpendicular to the cutter disc plane, and the pipe end positioning before beveling is completed; (4) After the pipe end positioning of the pipe 11 is completed, the position of the pipe 11 is fixed, then the cutter disc plane 10 is moved away from the pipe end face 12 by operating the pipe end face beveling machine 9, and the jackscrew of the fixing seat 1 is loosened to take out the positioning block 2.

[0031] In the subsequent processing, if the diameter of the pipe end face 12 is the same as that of the pipe end face 12 in the previous groove processing, only the positioning block 2 needs to be re-installed for the pipe end positioning operation of the pipe 11; if the diameter of the pipe end face 12 is not the same as that of the pipe end face 12 in the previous groove processing, the installation position of the fixing seat 1 on the cutter disc plane 10 is re-determined according to the size of the new pipe end face 12, and after the fixing seat 1 and the positioning block 2 are installed and fixed, the pipe end positioning operation of the pipe 11 can be performed according to the above steps.

[0032] In the above tool setting process, if the pipe end face 12 cannot be in contact with the end faces of the three positioning blocks 2, the direction of the pipe 11 needs to be adjusted until the pipe end face 12 is in contact with the end faces of the three positioning blocks 2.

[0033] The above examples are only used to illustrate the technical solutions of the present application and not to limit it, and those skilled in the art should understand that the specific embodiments of the present application can be modified or replaced by equivalents according to the above examples, and any modification or equivalent replacement that does not deviate from the spirit and scope of the present application is within the protection scope of the claims.
