Description

Technical Field

[0001] The utility model relates to the technical field of welding tooling, and more specifically to a tubular metal welding tooling. Background Art

[0002] Tubular metal welding usually refers to the connection of round or square pipes through welding technology to form a pipeline or frame structure. This welding can be manual welding, automatic or semi-automatic welding. Welding methods include but are not limited to arc welding, gas shielded welding, laser welding, electron beam welding, etc. The welding environment may be indoors at a welding workstation or outdoors on site. Factors that need to be considered in the welding process include the nature of the welding material, the shape and size of the pipe, the type of joint, the welding position, the welding parameters (such as current, voltage, welding speed, etc.) and the subsequent heat treatment and inspection process.

[0003] China Patent Authorization Announcement No.: CN220029207U provides a welding tool for metal parts processing. The solution is provided with a first fixing mechanism and a second fixing mechanism. The metal workpiece to be welded is adsorbed and fixed by an electromagnet, and a fastening bolt is moved along the arc groove to adjust the angle of the mounting plate and the electromagnet. Then, the fastening bolt is rotated to fix the mounting plate and the electromagnet, and then the angle of the two metal workpieces is adjusted. The fixing seat is placed on the electromagnet, and then two screws are rotated at the same time. The screw drives the extrusion seat to descend, and then the tubular workpiece is fixed. The two tubular workpieces are aligned, and the electromagnet is started so that the electric The magnet adsorbs and fixes the fixing seat, which can adjust the welding angle of the two metal workpieces and fix the tubular workpiece, thereby improving practicality. However, the above scheme does not take into account the particularity of the shape of the tubular metal when picking up and fixing the tubular metal. If the tubular metal is not picked up in the middle, the force arm caused by non-central picking up increases, thereby increasing the load on the picking device. The increase in the force arm means an increase in torque, which will cause additional stress on the mechanical parts of the picking device (such as rotating bearings, clamping mechanisms, etc.), accelerate wear, and the energy consumption of the fixing device during use is also large.

[0004] Therefore, a tubular metal welding tool is proposed to address the above problems. Utility Model Content

At the same time, the design of the support ring and the adjustment ring with an electromagnet, in conjunction with the adaptive clamping mechanism composed of a tension spring and a slide cylinder, can adapt to tubular workpieces of different sizes, simplify the operation process, and save energy consumption.

[0028] Example:

[0029] See also Figure 1 A tubular metal welding tool includes a welding table 1, a welding machine 11 and a welding seat 12 are fixedly connected to the top of the welding table 1, the welding seat 12 and the welding machine 11 are arranged on the same horizontal line, a pair of symmetrical support rods are fixedly connected to the top of the welding table 1, a moving component 2 is installed at one end of the pair of support rods close to each other, and a fixed component 3 is installed on the moving component 2.

[0030] This solution uses a servo motor 22 to control the moving assembly 2 that combines a reciprocating screw 23 and a screw sleeve 24, so that the fixing assembly 3 can be accurately moved to the center position of the tubular workpiece, thereby avoiding the extra force arm and torque generated when the non-center fixation occurs, reducing the stress and wear on the mechanical parts of the picking device, and extending the service life of the equipment. At the same time, the design of the support ring 31 and the adjustment ring 32 with an electromagnet, in conjunction with the adaptive clamping mechanism composed of a tension spring 36 and a slide cylinder 33, can adapt to tubular workpieces of different sizes, simplify the operation process, and save energy consumption. In the welding process, a method for positioning and fixing tubular workpieces that is both efficient and energy-saving is provided.

[0031] See also Figure 2The moving component 2 includes a moving column 21, both ends of the moving column 21 are fixedly connected to a pair of support rods, one end of the moving column 21 is fixedly connected to a servo motor 22, the output end of the servo motor 22 is fixedly connected to a reciprocating screw rod 23, one end of the reciprocating screw rod 23 is rotatably connected to the inner wall of the moving column 21, a screw sleeve 24 is installed on the outer periphery of the reciprocating screw rod 23, a connecting rod 25 is fixedly connected to the bottom end of the screw sleeve 24, a limiting block is fixedly connected to the top end of the screw sleeve 24, and a limiting groove slidably connected to the limiting block is opened on the inner wall of the moving column 21.

[0032] When welding a tubular workpiece, the present solution first transports the tubular workpiece to the upper side of the welding table 1 by means of a transport device, which may be a forklift or a suspension transport system. This technology belongs to the prior art and will not be described in detail herein. After the tubular workpiece corresponds to the fixed component 3, the electromagnet installed on the inner wall of the support ring 31 is first started, and the attraction of the magnetic block embedded in the outer end of the electromagnet adjustment ring 32 causes the adjustment ring 32 to rotate, so that the slide 33 is in the maximum clamping position, and then is supported and entered into the fixed component 3, and the servo motor 22 in the moving component 2 is started, so that the start of the servo motor 22 drives the reciprocating screw 23 to rotate, so that the reciprocating screw 23 drives the screw sleeve 24 to move to the middle of the tubular workpiece, and simultaneously drives the connecting rod 25 and the fixed component 3 to move to the middle of the tubular workpiece, and then the switch of the electromagnet is disconnected.

[0033] See also Figure 3-5 The fixing assembly 3 includes a supporting ring 31, an adjusting ring 32 and a fixing ring 34. The supporting ring 31 is fixedly connected to the connecting rod 25 and the fixing ring 34. The supporting ring 31 and the adjusting ring 32 are slidably connected. An electromagnet is installed on the inner wall of the supporting ring 31. A magnetic block matching the electromagnet is inlaid on the outer end of the adjusting ring 32. A pair of mutually symmetrical slide cylinders 33 are installed on the inner wall of the adjusting ring 32. The fixing ring 34 is composed of a pair of fixed semi-rings 35. A pair of mutually symmetrical arc grooves 37 are opened on the inner wall of the fixed semi-rings 35. A tension spring 36 is fixedly connected to the outer end of the slide cylinder 33. One end of the tension spring 36 is fixedly connected to the fixing semi-ring 35. A fixed block is slidably connected in the slide cylinder 33, and the fixed block is slidably connected to the arc groove 37.

[0034] In this scheme, when the switch of the electromagnet is turned off, the pull of the stretch spring 36 on the slide 33 synchronously pulls the slide 33 and the adjusting ring 32 to rotate, so that the fixed block in the slide 33 slides in the arc groove 37. Because the two ends of the shape of the arc groove 37 are at different distances from the center of the fixed semi-ring 35, that is, when the fixed block rotates counterclockwise under the pull of the stretch spring 36, the distance between the fixed block and the center of the fixed semi-ring 35 becomes closer and closer, thereby being able to adapt to tubular workpieces of different sizes. At the same time, when fixing the tubular workpiece, only the pull of the stretch spring 36 on the slide 33 is required, which saves resources. After the fixing is completed, the moving component 2 is started to drive the tubular workpiece to the welding seat 12, and the welding work is completed by the welding machine 11.

[0035] Working principle:

[0036] The tubular workpiece is first transported to the upper side of the welding table 1 by the transport device. After the tubular workpiece corresponds to the fixed component 3, the electromagnet installed on the inner wall of the support ring 31 is first started. The attraction of the magnetic block embedded in the outer end of the electromagnet adjustment ring 32 causes the adjustment ring 32 to rotate, so that the slide 33 is in the maximum clamping position, and then it is supported and entered into the fixed component 3. By starting the servo motor 22 in the moving component 2, the start of the servo motor 22 drives the reciprocating screw 23 to rotate, so that the reciprocating screw 23 drives the screw sleeve 24 to move to the middle of the tubular workpiece, and synchronously drives the connecting rod 25 and the fixing assembly 3 move to the middle of the tubular workpiece, then the switch of the electromagnet is disconnected. After the switch of the electromagnet is disconnected, under the action of the pulling force of the stretch spring 36 on the slide 33, the slide 33 and the adjusting ring 32 are synchronously pulled to rotate, so that the fixing block in the slide 33 slides in the arc groove 37, thereby adapting to tubular workpieces of different sizes. At the same time, when fixing the tubular workpiece, only the pulling force of the stretch spring 36 on the slide 33 is required, which saves resources. After the fixing is completed, the moving assembly 2 is started to drive the tubular workpiece to the welding seat 12, and the welding work is completed by the welding machine 11.

[0037] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
