Description

Technical Field

[0001] The invention relates to the field of welding facilities, and in particular to a welding tool for an assembled building mould. Background Art

[0002] Prefabricated buildings are a representative of modern industrialized production methods. They achieve the goal of efficient, environmentally friendly and energy-saving construction by transferring a large number of on-site operations in traditional construction methods to factories. During the manufacturing process of prefabricated building molds, the bottom mold and the side mold are usually connected together using a door-axis connection method, so that when demolding, the side mold can be turned down for easy demolding.

[0003] When the bottom mold and the side mold are connected, multiple ears are evenly arranged on the bottom mold and the side mold, and fixed by welding, and then the pin is passed through the ears of the two to connect the two together. When welding the ears, workers usually position each ear by manual measurement, and then weld. This operation method has a large manual positioning error, resulting in that after the ears on the bottom mold and the ears on the side mold are welded, when they are assembled together, the ears of the two cannot be accurately docked, which seriously affects the welding accuracy.

Then, the extension frame can be directly pulled to slide in the frame seat, so that the positioning column can be separated from the two sides of the No. 2 ear. Then, the stud can be loosened to move the pressure frame upward and away from the ground seat. Then, the frame seat can be moved to drive the positioning column to move sideways, so that the positioning column can be moved to the next No. 2 ear to position and weld the No. 1 ear at that location. This can be done by analogy to complete the welding operations of all No. 1 ears to meet the welding requirements. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0025] like Figure 1-Figure 7 The welding tool of an assembled building mold shown in the figure includes a base 1, a moving part is installed inside the base 1, a concave frame 7 is installed at the end of the moving part, rod rings 25 are fixedly installed at both ends of the concave frame 7, and the concave frame 7 plays a role in bearing the rod ring 25. Push rods 6 are slidably installed inside the two rod rings 25, and the rod rings 25 play a role in guiding the push rods 6. Positioning columns 23 are fixedly installed at the opposite ends of the two push rods 6, and the push rods 6 play a role in driving the positioning columns 23 to move. The positioning columns 23 can position the No. 1 ear 38 so that the No. 1 ear can be positioned. The axial hole on the ear 38 can be aligned with the axial hole on the No. 2 ear 39. The outer surface of the positioning column 23 is symmetrically extended with two limiting ears 24. The limiting ears 24 can limit the No. 1 ear 38 so that the No. 1 ear 38 remains upright. A connecting cap 19 is elastically installed in the middle of the upper end of the concave frame 7. Push frames 15 are rotatably installed on both sides of the connecting cap 19. The connecting cap 19 can drive the pushing frame 15 to move so as to drive the two push rods 6 to move toward each other synchronously. The ends of the two pushing frames 15 are rotatably connected to the two push rods 6 respectively, and welding parts are installed on the concave frame 7.

[0026] The opposite ends of the two push rods 6 are coaxially inlaid with limit caps 26, which prevent the push rods 6 and the rod ring 25 from separating. A pull rod 11 is coaxially extended from the rear end of the connecting cap 19, and a rod sleeve 13 is fitted on the outer surface of the pull rod 11. The pull rod 11 and the rod sleeve 13 guide the connecting cap 19. The lower end of the rod sleeve 13 is fixed to the concave frame 7. The end of the pull rod 11 is inlaid with a holding frame 12, which facilitates the holding and pushing of the pull rod 11.

[0027] A tensioning spring 20 is wound around the outside of the pulling rod 11, and one end of the tensioning spring 20 is fixed to the rod sleeve 13. The tensioning spring 20 can push the connecting cap 19, so that the moving connecting cap 19 drives the pushing frame 15 to move, and then drives the two push rods 6 to move synchronously toward each other. The other end of the tensioning spring 20 is fixed to the holding frame 12. Both ends of the base 1 are vertically fixed with fixing frames 2, and the fixing frames 2 serve to carry the supporting ears 3 and the positioning ears 4. The opposite ends of the two fixing frames 2 are symmetrically fixed with two supporting ears 3, and the supporting ears 3 serve to support and limit the side mold 37. The front ends of the two fixing frames 2 are fixedly installed with positioning ears 4, and the two positioning ears 4 are symmetrically arranged, and the positioning ears 4 serve to limit the bottom mold 36.

[0028] The welding part includes two guide sleeves 17 symmetrically and slidably mounted on the concave frame 7, the guide sleeves 17 play a role in guiding the welding gun 22, a connecting frame 18 is fixedly mounted between the upper ends of the two guide sleeves 17, and two gun racks 21 are symmetrically extended from the front end of the connecting frame 18, the gun rack 21 plays a role in supporting the welding gun 22, and welding guns 22 are fixedly mounted at the ends of the two gun racks 21. The two welding guns 22 are symmetrically arranged and can weld the joints of the two No. 1 ears 38 and the side mold 37 at the same time. The welding gun 22 is connected to an external welding machine for use. Since welding by means of the welding gun 22 is a prior art and has been widely used, it is not elaborated in detail here.

[0029] The moving part includes a frame seat 8 that is slidably installed inside the base 1, and an extended frame 5 is slidably installed inside the frame seat 8. The frame seat 8 plays a role in supporting the extended frame 5. The end of the extended frame 5 is fixed to the concave frame 7, and the extended frame 5 plays a role in supporting the concave frame 7. Guide ears 9 are extended from the upper and lower ends of the frame seat 8. The guide ears 9 pass through the upper and lower ends of the base 1, and the guide ears 9 prevent the frame seat 8 from separating from the base 1. A special-shaped frame 30 is fixedly installed on the upper end of the frame seat 8. The special-shaped frame 30 is located behind the guide ears 9. A stud 32 is screwed through the end of the special-shaped frame 30, and the special-shaped frame 30 plays a role in supporting the stud 32. A pressing frame 35 is rotatably installed at the lower end of the stud 32. The stud 32 can drive the pressing frame 35 to move up and down to loosen and tighten the frame seat 8, and the pressing frame 35 is pressed tightly on the base 1.

[0030] The upper and lower end surfaces of the base 1 are both provided with a slide groove 14, and the guide ear 9 is fitted inside the slide groove 14. The slide groove 14 cooperates with the guide ear 9. The upper end of the stud 32 is coaxially fixed with a handwheel 16, and the handwheel 16 facilitates the rotation of the stud 32. The front end of the special-shaped frame 30 is fixedly installed with a groove seat 33, and the interior of the groove seat 33 is fitted with a limiting block 34. The end of the limiting block 34 is fixed to the upper end of the pressing frame 35, and the cooperation between the groove seat 33 and the limiting block 34 prevents the pressing frame 35 from rotating.

[0031] A bearing sleeve 10 is fixedly installed at the rear end of the special-shaped frame 30, and a locking pin 27 is coaxially arranged inside the bearing sleeve 10. The bearing sleeve 10 serves to support the locking pin 27. The two ends of the locking pin 27 respectively pass through the upper and lower ends of the bearing sleeve 10, and the locking pin 27 slides with the bearing sleeve 10. The lower end of the locking pin 27 passes through the upper end of the frame seat 8 and the upper end of the extension frame 5 in turn, and the locking pin 27 slides with the frame seat 8 and the extension frame 5. The locking pin 27 fixes the frame seat 8 and the extension frame 5 together.

[0032] A pin cap 29 is coaxially inlaid on the outer surface of the locking pin 27, and the pin cap 29 is fitted to the inner surface of the bearing sleeve 10. The pin cap 29 is pushed by the pin fixing spring 28. The outer side of the locking pin 27 is wrapped with a pin fixing spring 28. The upper end of the pin fixing spring 28 is fixed to the inner top surface of the bearing sleeve 10, and the pin fixing spring 28 plays the role of pushing the locking pin 27 out. The lower end of the pin fixing spring 28 is fixed to the upper end of the pin cap 29. A pull ring 31 is fixedly installed on the upper end of the locking pin 27, and the pull ring 31 plays the role of facilitating the pulling of the locking pin 27.

[0033] During welding, the bottom mold 36 with the second ear 39 welded thereto is placed between the two positioning ears 4. At this time, the notches on the two positioning ears 4 fit the corners of the bottom mold 36 to limit the bottom mold 36 so that the two positioning columns 23 can be located on both sides of the second ear 39 and aligned with the axial hole of the second ear 39. Then, the side mold 37 is placed on the supporting ear 3. At this time, the supporting ear 3 is pressed against the inner corner of the side mold 37 to support and limit the side mold 37 so that the side mold 37 can be aligned with the bottom mold 36. Then, the pull rod 11 is pulled. The two positioning posts 23 are pushed to move in opposite directions. At this time, the tensioning spring 20 contracts and deforms. Then, the two No. 1 connecting ears 38 are respectively inserted on the two positioning posts 23 to position the No. 1 connecting ear 38 through the positioning posts 23 so that the shaft hole on the No. 1 connecting ear 38 can be aligned with the shaft hole on the No. 2 connecting ear 39. Then, the pulling rod 11 is released to allow the tensioning spring 20 to recover its deformation to push the connecting cap 19. At this time, the pulling rod 11 slides in the rod sleeve 13 to guide the connecting cap 19, so that the moving connecting cap 19 drives the pushing frame 15 to move, thereby bringing The two push rods 6 are moved toward each other synchronously to press the two No. 1 ears 38 against the two sides of the No. 2 ears 39 respectively, and then the connecting frame 18 is pushed to drive the two welding guns 22 to move. At this time, the guide sleeve 17 slides on the concave frame 7 to guide the welding gun 22, so that the moving welding gun 22 is used to weld the joint of the No. 1 ear 38 and the side mold 37, so as to weld the two No. 1 ears 38 and the side mold 37 together at the same time. After the welding is completed, the pulling rod 11 can be pushed first to make the two positioning columns 23 move oppositely to disengage from the No. 1 ear 38. Then, the pull ring 31 is pulled to disengage the locking pin 27 pushed out by the fixing pin spring 28 from between the extending frame 5 and the frame seat 8, and then the extending frame 5 is directly pulled to slide in the frame seat 8, so that the positioning column 23 is disengaged from both sides of the No. 2 ear 39, and then the stud 32 is loosened to allow the pressing frame 35 to move up and disengage from the base 1, and then the frame seat 8 is moved to drive the positioning column 23 to move sideways, so that the positioning column 23 moves to the next No. 2 ear 39, so as to position and weld the No. 1 ear 38 there, and so on to complete the welding operation of all the No. 1 ears 38.
