Description

Technical Field

[0001] The present invention belongs to the technical field of welding positioning, and specifically refers to a slag-removing type welding positioning device. Background Art

[0002] When performing circumferential welding on pipe fittings, the circumferential seams of the two pipe fittings to be welded need to be butted and then clamped in a clamping device, and then a welding device is used to weld the spliced circumferential seam.

[0003] Currently, the existing welding positioning devices have the following problems:

[0004] When the existing welding positioning device positions the pipe fittings by means of magnetism, the heat generated at the welding part is easily conducted along the pipe fitting and contacts the magnetic adsorption part, reducing the adsorption force of the magnetic adsorption component, affecting the stable positioning of the magnetic positioning structure for the pipe fitting, resulting in deviation in the welding of the circumferential seam of the pipe fitting, and the traditional welding positioning device does not have the ability to detect the splicing welding quality of the pipe fittings after welding. Therefore, it cannot meet the current usage requirements for welding positioning devices. Summary of the Invention

[0005] In view of the above situation, to overcome the defects of the prior art, this solution provides a slag-removing type welding positioning device that can block the heat conduction generated in the welding area from entering the magnetic adsorption positioning area with low energy consumption, ensure the positioning accuracy of the magnetic adsorption structure for the workpiece, and can test the welding quality after welding.

[0006] The technical solution adopted in this solution is as follows: A slag-removing type welding positioning device proposed in this solution includes a positioning table, a guiding frame, a butt-type magnetic adsorption mechanism, and a slag-collecting heat insulation mechanism. The guiding frame is arranged on the upper wall of the positioning table, the butt-type magnetic adsorption mechanism is arranged on the guiding frame, the slag-collecting heat insulation mechanism is arranged on the butt-type magnetic adsorption mechanism. The butt-type magnetic adsorption mechanism includes a driving mechanism, a fixing and adsorption mechanism, and a welding mechanism. The driving mechanism is arranged on the inner wall of the guiding frame, the fixing and adsorption mechanism is arranged at both ends of the driving mechanism, and the welding mechanism is arranged in the middle part of the driving mechanism. The slag-collecting heat insulation mechanism includes a butting mechanism, a slag discharging mechanism, a temperature difference mechanism, and an isolation mechanism. The butting mechanism is arranged on the side of the driving mechanism away from the fixing and adsorption mechanism, the slag discharging mechanism is arranged on the bottom wall of the butting mechanism, the temperature difference mechanism is arranged on the side wall of the slag discharging mechanism, and the isolation mechanism is arranged on the side wall of the slag discharging mechanism above the temperature difference mechanism.

[0007] As a further optimization of the solution of this case, the driving mechanism includes a guide rod, a guide spring, a driving electromagnet and a driving frame. The guide rods are symmetrically arranged on the inner walls at both ends of the guide frame. The driving frames are symmetrically arranged at both ends of the guide rod, and the driving frames are slidably arranged outside the guide rod. The guide spring is arranged between the guide frame and the driving frame outside the guide rod. The driving electromagnet is arranged on the side wall of the guide frame outside the guide spring; the fixing and sucking mechanism includes a sucking electromagnet, a groove, an auxiliary sucking soft iron plate and a sliding magnetic ring. The groove is arranged on the inner wall of the driving frame, and the groove is provided with an opening at one end. The sucking electromagnet is rotatably arranged on the inner wall of the groove. A plurality of groups of the auxiliary sucking soft iron plates are arranged on the side of the sucking electromagnet away from the driving frame. The sliding magnetic ring is arranged on the side wall of the driving frame outside the guide spring, and the sliding magnetic ring is arranged opposite to the sucking electromagnet; the welding mechanism includes a welding frame and an annular platform. The welding frame is arranged at the middle part of the guide rod, and the annular platform is arranged between the welding frames.

[0008] During use, in the initial state, the guide spring is in an extended state. The guide spring pushes the driving frames to move relative to each other along the guide rod. The driving frames drive the distance between the sucking electromagnets to shorten, so as to splice and position the pipe fittings to be welded. The driving electromagnet is energized to generate magnetism. The driving electromagnet and the sliding magnetic ring are arranged with opposite polarities. The driving electromagnet adsorbs the sliding magnetic ring by magnetic force. The sliding magnetic ring drives the driving frame to slide along the guide rod by using the deformation of the guide spring. The driving frames move away from each other, and the distance between the sucking electromagnets increases. Insert the pipe fittings to be welded between the auxiliary sucking soft iron plate and the sucking electromagnet. One end of the pipe fitting away from the auxiliary sucking soft iron plate protrudes from the inside of the sucking electromagnet. The sucking electromagnet is energized to generate magnetism. The sucking electromagnet adsorbs the pipe fitting by magnetic force. The outer diameter of the pipe fitting is the same as the inner diameters of the sucking electromagnet and the auxiliary sucking soft iron plate. The sucking electromagnet magnetizes the auxiliary sucking soft iron plate by magnetic force. After being magnetized, the auxiliary sucking soft iron plate adsorbs the pipe fitting. Then, the magnetism of the driving electromagnet weakens. The sliding magnetic ring drives the driving frame to slide along the guide rod by using the deformation of the guide spring. The magnetic pole of the driving electromagnet changes. The driving electromagnet and the sliding magnetic ring are arranged with the same polarity. The driving electromagnet is fixed on the side wall of the guide frame and pushes the sliding magnetic ring by repulsive force. The sliding magnetic ring drives the pipe fitting through the driving frame, and the welding surfaces are closely attached. The magnetic field intensity between the sucking electromagnet and the pipe fitting is greater than the magnetic field intensity between the driving electromagnet and the sliding magnetic ring. Therefore, the stability after the positioning of the pipe fitting can be ensured. Install the welding equipment on the upper wall of the annular platform. The welding part of the welding equipment passes through the opening of the annular platform and is located above the weld after the splicing of the pipe fittings. The power end of the welding equipment is attached to the splicing seam of the pipe fittings. The welding equipment welds the pipe fittings.

[0009] Preferably, the involution mechanism includes a collection rack, a half semi-cylindrical barrel, and a load-bearing ring. The collection rack is arranged on the side of the driving rack away from the auxiliary suction soft iron plate. The half semi-cylindrical barrel is arranged on the side of the collection rack away from the driving rack. The load-bearing ring is arranged on the upper wall of the half semi-cylindrical barrel. The slag discharging mechanism includes a half slag discharging port and a half slag storage barrel. The half slag discharging port is arranged on the bottom wall of the half semi-cylindrical barrel. The half slag storage barrel is arranged on the inner wall of the half slag discharging port, and the half slag storage barrels are arranged oppositely. The temperature difference mechanism includes a thermoelectric power generation sheet group, a rectifier, and a storage battery. The thermoelectric power generation sheet group is arranged through the inner wall of one end of the half slag storage barrel away from the half slag discharging port. The rectifier and the storage battery are respectively arranged on the side wall of the guiding rack. The thermoelectric power generation sheet group is electrically connected to the rectifier, and the rectifier is electrically connected to the storage battery. The isolation mechanism includes a thermoelectric refrigeration sheet group, an isolation copper ring, a temperature conducting copper column, and a heat insulation coating. The thermoelectric refrigeration sheet group is arranged through the inner wall of the half slag storage barrel above the thermoelectric power generation sheet group. The isolation copper ring is arranged on the side of the driving rack close to the half semi-cylindrical barrel. The temperature conducting copper column is arranged between the isolation copper ring and the refrigeration end of the thermoelectric refrigeration sheet group. The heat insulation coating is respectively arranged on the outer sides of the non-connected parts of the isolation copper ring and the temperature conducting copper column and on the side of the isolation copper ring away from the driving rack.

[0010] During use, the part of the pipe fitting protruding from the adsorption electromagnet penetrates through the load-bearing ring and is vertically arranged on the side of the half semi-cylindrical barrel away from the collection rack. After the pipe fitting moves and fits with the driving rack, the driving rack synchronously drives the half semi-cylindrical barrel, the half slag discharging port, and the half slag storage barrel to fit respectively. The half semi-cylindrical barrel, the half slag discharging port, and the half slag storage barrel form a slag storage cavity. The welding slag generated during the welding of the pipe fitting falls into the interior of the half semi-cylindrical barrel. The welding slag inside the half semi-cylindrical barrel falls into the interior of the half slag storage barrel through the half slag discharging port. Since the welding slag has a certain temperature, the temperature inside the slag storage cavity formed by the half semi-cylindrical barrel, the half slag discharging port, and the half slag storage barrel rises. The two ends of the induction surface of the thermoelectric power generation sheet group have different temperatures to generate current. The current generated by the thermoelectric power generation sheet group is processed by the rectifier and then stored in the storage battery.

[0011] Specifically, a controller is arranged on the side of the positioning table close to the rectifier and the storage battery.

[0012] Among them, the controller is electrically connected to the driving electromagnet, the adsorption electromagnet, the thermoelectric power generation sheet group, the rectifier, the storage battery, and the thermoelectric refrigeration sheet group respectively.

[0013] Preferably, the model of the controller is SYC89C52RC-401.

[0014] The beneficial effects achieved by this solution with the above structure are as follows:

[0015] Compared with the prior art, this solution adopts a combination of a blocking structure and a slag storage structure. Through the set opposed magnetic adsorption mechanism and slag collection heat insulation mechanism, under the combined use of a driving mechanism, a fixed adsorption mechanism, a welding mechanism, an alignment mechanism, a slag discharging mechanism, a temperature difference mechanism and an isolation mechanism, the heat generated by the welding slag is collected, and the temperature difference effect of the thermoelectric power generation sheet group is used to convert the heat into electric energy to supply energy for the thermoelectric refrigeration sheet group to block the conduction heat generated by welding. This can not only reduce the cooling energy consumption of the thermoelectric refrigeration sheet group, but also ensure the stability of the adsorption electromagnet for positioning the pipe fittings. Moreover, through the relative movement of the driving frame, one end of the welded pipe fitting is suspended, enabling the welding quality of the circumferential weld between the pipe fittings to be tested, thereby improving the operation efficiency of the pipe fitting welding positioning device to a certain extent.

[0033] The involution mechanism 16 includes a collection rack 17, a half semi-cylindrical barrel 18 and a load-bearing ring 19. The collection rack 17 is arranged on the side of the driving rack 33 away from the auxiliary suction soft iron plate 11.

The heat insulation coating 31 is respectively arranged on the outer sides of the non-connected parts of the isolation copper ring 29 and the heat conduction copper column 30 and on the side of the isolation copper ring 29 away from the driving rack 33.

[0034] A controller 32 is arranged on one side of the positioning table 1 close to the rectifier 25 and the storage battery 26.

[0035] The controller 32 is respectively electrically connected to the driving electromagnet 7, the adsorption electromagnet 9, the thermoelectric power generation sheet group 24, the rectifier 25, the storage battery 26 and the thermoelectric refrigeration sheet group 28.

[0036] The model of the controller 32 is SYC89C52RC-401.

[0037] During specific use, in the initial state, the guiding spring 6 is set to be elongated. The guiding spring 6 pushes the driving frame 33 to move relative to the guiding rod 5. The driving frame 33 drives the distance between the adsorption electromagnets 9 to shorten, so as to splice and position the pipe fittings to be welded. The controller 32 controls the driving electromagnet 7 to start. The driving electromagnet 7 is energized to generate magnetism. The driving electromagnet 7 and the sliding magnetic ring 34 are arranged with opposite polarities. The controller 32 controls the current flowing into the driving electromagnet 7 to increase. The driving electromagnet 7 adsorbs the sliding magnetic ring 34 by magnetic force. The sliding magnetic ring 34 drives the driving frame 33 to slide along the guiding rod 5 by using the deformation of the guiding spring 6. The driving frame 33 moves away from each other, and the distance between the adsorption electromagnets 9 increases. The pipe fittings to be welded are inserted between the auxiliary adsorption soft iron plate 11 and the adsorption electromagnets 9. One end of the pipe fitting far from the auxiliary adsorption soft iron plate 11 protrudes from the inside of the adsorption electromagnet 9. The part of the pipe fitting protruding from the adsorption electromagnet 9 penetrates through the load-bearing ring 19 and is vertically arranged on the side of the half semi-cylindrical barrel 18 far from the collection rack 17. The controller 32 controls the adsorption electromagnet 9 to start. The adsorption electromagnet 9 is energized to generate magnetism. The controller 32 controls the current flowing into the adsorption electromagnet 9 to increase. The adsorption electromagnet 9 adsorbs the pipe fitting by magnetic force. The outer diameter of the pipe fitting is the same as the inner diameters of the adsorption electromagnet 9 and the auxiliary adsorption soft iron plate 11. The adsorption electromagnet 9 magnetizes the auxiliary adsorption soft iron plate 11 by magnetic force, and the auxiliary adsorption soft iron plate 11 adsorbs the pipe fitting after magnetization;

[0038] Subsequently, the controller 32 controls the current flowing into the driving electromagnet 7 to decrease. The magnetism of the driving electromagnet 7 weakens. The sliding magnetic ring 34 drives the driving frame 33 to slide along the guiding rod 5 by using the deformation of the guiding spring 6. The magnetic pole of the driving electromagnet 7 changes. The driving electromagnet 7 and the sliding magnetic ring 34 are arranged with the same polarities. The driving electromagnet 7 is fixed on the side wall of the guiding frame 2 and pushes the sliding magnetic ring 34 by repulsion. The sliding magnetic ring 34 drives the pipe fitting through the driving frame 33, and the welding surfaces are closely attached. The magnetic field strength between the adsorption electromagnet 9 and the pipe fitting is greater than the magnetic field strength between the driving electromagnet 7 and the sliding magnetic ring 34, so as to ensure the stability of the pipe fitting after positioning;

[0039] Install the welding equipment on the upper wall of the annular platform 14. The welding part of the welding equipment penetrates through the opening of the annular platform 14 and is located above the weld seam after the pipe fittings are spliced. The power end of the welding equipment is attached to the splicing seam of the pipe fittings. The welding equipment welds the pipe fittings. When the pipe fittings are welded together, rotate the pipe fittings, and the spliced pipe fittings rotate synchronously, so as to weld the circumferential seam of the pipe fittings;

[0040] After the pipe fittings are fitted with the driving frame 33, the driving frame 33 synchronously drives the half-semi-cylinder 18, the half-slag opening 21 and the half-slag storage cylinder 22 to fit together, and the half-semi-cylinder 18, the half-slag opening 21 and the half-slag storage cylinder 22 form a slag storage cavity. The welding slag generated during the welding process of the pipe fittings falls into the half-semi-cylinder 18, and the welding slag inside the half-semi-cylinder 18 falls into the half-slag storage cylinder 22 through the half-slag opening 21. Since the welding slag has a certain temperature, the half-semi-cylinder 18, the half-slag opening 21 and the half-slag storage cylinder 22 are The temperature inside the slag storage cavity formed by the side slag storage barrel 22 rises, and the temperature difference at both ends of the induction surface of the thermoelectric power generation sheet group 24 is different to generate current. The current generated by the thermoelectric power generation sheet group 24 is processed by the rectifier 25 and stored in the battery 26. The microscopic particles (such as electrons, atoms, etc.) inside the adsorption electromagnet 9 will form an orderly arrangement in the magnetic field, thereby generating magnetism. However, as the temperature rises, the thermal motion of these microscopic particles will intensify, causing their orderly arrangement to be disrupted, thereby weakening the magnetism of the adsorption electromagnet 9;

[0041] In order to prevent the heat conducted during pipe welding from affecting the adsorption magnetic force of the adsorption electromagnet 9, the controller 32 controls the thermoelectric cooling sheet group 28 to start, and the thermoelectric cooling sheet group 28 cools the temperature-conducting copper column 30 through the cooling end. The inner diameter of the insulating copper ring 29 is consistent with the outer diameter of the pipe. The temperature-conducting copper column 30 cools the pipe at the contact part through the insulating copper ring 29, thereby blocking the heat conduction inside the pipe, ensuring the stability of the magnetic attraction positioning of the pipe by the adsorption electromagnet 9. The heat generated by the thermoelectric cooling sheet group 28 enters the slag storage cavity formed by the half-semi-cylinder 18, the half-slag lower port 21 and the half-slag storage cylinder 22, increasing the temperature difference between the sensing surfaces at both ends of the temperature difference power generation sheet group 24, and increasing the storage capacity of the current inside the battery 26, thereby reducing the energy consumption of the thermoelectric cooling sheet group 28 for cooling the pipe;

[0042] Subsequently, the controller 32 controls the adsorption electromagnet 9 at one end of the guide frame 2 to be powered off and demagnetized, and the controller 32 controls the driving electromagnet 7 to start, and the driving electromagnet 7 is energized to generate magnetism. The driving electromagnet 7 is fixed on the side wall of the guide frame 2 and adsorbs the sliding magnetic ring 34 by magnetic force. The sliding magnetic ring 34 uses the deformation of the guide spring 6 to drive the driving frame 33 to slide along the guide rod 5, and the driving frame 33 moves in opposite directions. The driving frame 33 drives the spliced pipe fittings to be pulled out from the adsorption electromagnet 9 at the other end of the guide frame 2, and the pipe fittings are completely separated from the support of the load-bearing ring 19. The pipe fittings use their own weight to perform a suspended test on the welding quality. When there are no cracks in the welding part between the pipe fittings, the adsorption electromagnet 9 at the other end of the guide frame 2 is powered off and demagnetized, and the welded pipe fittings are pulled out from the adsorption electromagnet 9 to complete the welding process after the pipe fittings are spliced; the above operation can be repeated the next time it is used.

[0044] The above describes the present solution and its implementation manner. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present solution, and the actual structure is not limited thereto.
