Description

Technical Field

[0001] The utility model relates to the technical field of welding tools, in particular to a pipe welding device with an automatic rotating function. Background Art

[0002] Welding, also known as fusion, is a manufacturing process and technology that joins metals or other thermoplastic materials by heating, high temperature or high pressure. There are many sources of energy for modern welding, including gas flame, arc, laser, electron beam, friction and ultrasonic.

[0003] When welding different workpieces, in addition to different welding forms, different devices are often used to fix workpieces of different shapes in order to facilitate rapid welding and improve welding quality. For example, when welding some round pipes, it is often necessary to weld some end plugs at the key ends, so that the pipes can be connected to other parts in the finished product through the end plugs. When welding the end plugs, the edge of the end plug needs to be aligned with the edge of the pipe to ensure the quality after welding.

[0004] In the prior art, when welding pipe fittings and end plugs or key parts with other key parts, conventional clamps are mostly used for clamping and fixing, and then welding tools, manual welding or automatic welding by robotic arms are used. After one side is welded, it is flipped by the clamp. When flipping, one clamp needs to be loosened and flipped with another clamp. This flipping method is more troublesome to operate, and because the weld has not completely cooled down and the strength has not reached the full use strength when flipping, the weight of the pipe fitting or end plug itself will cause a certain deformation of the weld, which has a certain impact on the quality of the final product. Utility Model Content

[0005] The utility model aims to provide a pipe welding device with an automatic rotation function, so as to solve the problem in the prior art that conventional clamping tools may affect the weld when performing flip welding on round pipes.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A pipe welding device with automatic rotation function comprises a processing table, on which a fixed seat, an end support seat, a pipe support seat and a vertical plate are sequentially arranged at intervals, the fixed seat is provided with a rotating hole aligned with the end support seat, a rotating rod is rotatably arranged in the rotating hole, the end of the rotating rod away from the end support seat is connected to a driving member for driving the rotating rod to rotate, and a clamping rod facing the pipe support seat is rotatably arranged on the vertical plate; a welding module is arranged on the side of the processing table.

[0008] A further technical solution is that the upper side of the end support seat is recessed with a first arc-shaped groove, and the upper side of the pipe support seat is recessed with a second arc-shaped groove.

[0009] A further technical solution is that a plurality of long strip-shaped rotating grooves are arranged around the groove wall of the first groove, a rotating roller is rotatably arranged in the rotating groove, and the upper part of the rotating roller protrudes from the rotating groove; the axial direction of the rotating roller is the same as the axial direction of the rotating rod.

[0010] A further technical solution is that a threaded hole facing the pipe support seat is provided on the vertical plate, and a threaded rod is connected to the threaded hole in a matching manner. One end of the threaded rod facing the pipe support seat is coaxially connected to the clamping rod, and the other end is connected to a knob plate on the side of the vertical plate away from the pipe support seat.

[0011] A further technical solution is that a first top plate is provided at one end of the clamping rod facing the pipe support seat, and a second top plate is provided at one end of the rotating rod facing the end support seat.

[0012] A further technical solution is that the welding module is installed on the side of the processing table through a robot arm.

[0013] A further technical solution is that the welding module is installed on the side of the processing table through a movable frame, a lifting plate is vertically arranged on the movable frame, a lifting rod is vertically installed on the upper end of the lifting plate, the lifting end of the lifting rod is arranged downward and connected to the welding module.

[0014] A further technical solution is that the driving member is a servo motor, and the output shaft of the servo motor is coaxially connected to the rotating rod.

[0015] Compared with the prior art, the utility model has at least one of the following beneficial effects: 1. Before welding, the pipe fittings and end plugs are spliced ​​on the end support seat and the pipe fitting support seat, so that the weld is in an aligned state before splicing; 2. With the help of the rotating rod to support the end plug, the clamping rod pushes the pipe fitting toward the end plug, so that the weld can be in a clamped state. In this way, during welding, even if a slight collision occurs, the weld will not be offset, thereby improving the welding quality; 3. By setting a driving member to drive the rotating rod to rotate, different positions of the weld can be brought into contact with the welding module during the welding process. In this way, during the welding process, the welding module will not move, and the weld can be completely welded by rotating, thereby improving the welding efficiency. At the same time, with the help of the end support seat and the pipe fitting support seat, the force is evenly distributed when the pipe fitting and the end plug rotate, and no deformation will occur.

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0022] Figures 1 to 4 Shown is an embodiment of the utility model.

[0023] Embodiment 1:

[0024] like Figure 1As shown, a pipe welding device with automatic rotation function includes a processing table 1, on which a fixed seat 2, an end support seat 3, a pipe support seat 4 and a vertical plate 5 are arranged in sequence, and a rotating hole 6 aligned with the end support seat 3 is arranged on the fixed seat 2, and a rotating rod 7 is rotatably arranged in the rotating hole 6, and a driving member 8 for driving the rotating rod 7 to rotate is connected to the end of the rotating rod 7 away from the end support seat 3, and a clamping rod 9 facing the pipe support seat 4 is rotatably arranged on the vertical plate 5; a welding module 10 is arranged on the side of the processing table 1. Before welding, the pipe and the end plug are spliced ​​on the end support seat 3 and the pipe support seat 4, so that the weld is in an aligned state before splicing. With the help of the rotating rod 7 to support the end plug, the clamping rod 9 pushes the pipe toward the end plug, so that the weld can be in a compressed state, so that during welding, even if a slight collision occurs, the weld will not be offset, thereby improving the welding quality. By setting a driving member 8 to drive the rotating rod 7 to rotate, different positions of the weld can be brought into contact with the welding module 10 during the welding process. In this way, the welding module 10 can be kept stationary during the welding process, and the weld can be completely welded by rotating the weld. While improving the welding efficiency, the end support seat 3 and the pipe support seat 4 can be used to ensure that the force is evenly distributed when the pipe and the end plug rotate, and no deformation will occur. The welding module 10 can use any welding gun in the prior art, and its welding form, such as arc welding and argon arc welding, can be adjusted according to needs, and this embodiment does not limit it. In addition to the above-mentioned method according to the fixed seat 2, the end support seat 3, the pipe support seat 4 and the vertical plate 5, as Figure 2 As shown, welding can be performed at one end of the pipe fitting, and it can also be arranged in the form of a fixed seat 2, an end support seat 3, a pipe fitting support seat 4, a pipe fitting support seat 4, an end support seat 3 and a vertical plate 5, so that the end plugs at both ends of the pipe fitting can be fixed and then welded.

[0025] The upper side of the end support seat 3 is recessed with a first circular arc groove 11, and the upper side of the pipe support seat 4 is recessed with a second circular arc groove 12. By providing the first groove 11 and the second groove 12, the side wall of the end plug and the pipe can be fitted and fixed, so that the pipe and the end plug will not be offset during the assembly and welding process, and the side wall of the pipe and the end plug can also be limited during the rotation process to avoid offset and uneven welds.

[0026] Embodiment 2:

[0027] Based on the above embodiments, Figure 4As shown, a plurality of long strip-shaped rotating grooves 13 are arranged around the groove wall of the first groove 11, and a rotating roller 14 is rotatably arranged in the rotating groove 13, and the upper part of the rotating roller 14 protrudes out of the rotating groove 13; the axial direction of the rotating roller 14 is the same as the axial direction of the rotating rod 7. By arranging the rotating roller 14 and the rotating groove 13, when welding, a plurality of rotating rollers 14 are attached to the outer wall of the pipe fitting, and when the pipe fitting is rotated, the rotating roller 14 rotates in the rotating groove 13 to make the pipe fitting rotate more smoothly in the first groove 11, and at the same time, the long strip-shaped rotating tube can play a good supporting role for the pipe fitting.

[0028] Embodiment 3:

[0029] Based on the above embodiments, Figure 3 As shown, the vertical plate 5 is provided with a threaded hole 15 facing the pipe support seat 4, and the threaded hole 15 is matched with a threaded rod 16 connected to the inner thread. One end of the threaded rod 16 facing the pipe support seat 4 is coaxially connected to the clamping rod 9, and the other end is connected to a knob plate 17 on the side of the vertical plate 5 away from the pipe support seat 4. When clamping the pipe and the end plug, the clamping rod 9 is moved toward the pipe by rotating the knob plate 17, so that the pipe and the end plug can be gradually compressed with the clamping rod 9 cooperating with the rotating rod 7, so that the welding seam is tightly fitted together, which is convenient for welding. After welding is completed, the welded pipe can be easily taken out by rotating the knob plate 17 in the opposite direction.

[0030] The first top plate 18 is provided at one end of the clamping rod 9 facing the pipe support seat 4, and the second top plate 19 is provided at one end of the rotating rod 7 facing the end support seat 3. By providing the first top plate 18 and the second top plate 19, the contact area with the pipe end and the end plug end can be increased, thereby improving the stability of clamping.

[0031] Embodiment 4:

[0032] Based on the above embodiment, the welding module 10 is installed on the side of the processing table 1 through a robot arm. By setting the robot arm, the robot arm can drive the welding module 10 to approach the welding seam for welding and move away from the welding seam after welding is completed.

[0033] Embodiment 5:

[0034] Based on the above embodiments, Figure 2As shown, the welding module 10 is installed on the side of the processing table 1 through a mobile frame 20, and a lifting plate 21 is vertically arranged on the mobile frame 20. A lifting rod is vertically installed on the upper end of the lifting plate 21, and the lifting end of the lifting rod is arranged downward and connected to the welding module 10. By setting the mobile frame 20 and cooperating with the lifting rod, the welding module 10 can be driven to move up and down. When welding is required, the welding module 10 is driven to move downward to the welding position, and after welding is completed, it moves upward. The lifting rod can also use a screw motor or the like to drive the welding module 10 to move up and down.

[0035] The driving member 8 is a servo motor, and the output shaft of the servo motor is coaxially connected to the rotating rod 7. By setting the servo motor, the rotation speed and the rotation angle can be controlled, so that the weld can be more uniform during welding, thereby improving the welding quality.
