Description

Technical Field

[0001] The present invention relates to the technical field of positioning devices, and more specifically, to a welding positioning device and method for aluminum alloy formwork used in building construction. Background Art

[0002] Aluminum profiles refer to various cross-sectional-shaped metal materials obtained by processing aluminum and aluminum alloy materials through extrusion, stretching, die pressing and other processing techniques. They have the advantages of light weight, high strength, corrosion resistance, easy processing, beauty, etc., so they are widely used in modern manufacturing. Aluminum profiles also have good plasticity and can be shaped into different cross-sections through extrusion, die pressing, stamping and other processing techniques to meet various engineering requirements. Specifically in use, in order to adapt to specific size requirements for use in various fields such as construction, manufacturing, and engineering.

[0003] When cutting or welding aluminum alloy formwork, due to its sharpness and relatively large mass, it is not convenient for manual operation. At this time, a positioning device is needed to fix it so that it can be processed more easily. However, the existing positioning devices for processing aluminum alloy formwork in building engineering have certain drawbacks. First of all, the deflection angle of the existing positioning devices for processing aluminum alloy formwork in building engineering is limited. In actual use, the butt joint surfaces between aluminum profiles or between aluminum profiles and other structures need to be in an inclined plane state under the vertical direction or in an inclined plane state under the horizontal direction, that is, the cross-sectional styles of aluminum profiles are diverse. It is difficult for the existing positioning devices to deflect, combine and splice the corresponding aluminum alloy formwork to form different shapes. And the existing positioning devices for processing aluminum alloy formwork in building engineering often clamp both sides of the part to be processed, and cannot fully fix the aluminum alloy formwork with irregular surfaces or convex or concave structures. In this way, the applicable range of common fixing devices is very small, resulting in the splicing accuracy of aluminum alloy formwork not being guaranteed. Summary of the Invention

Detailed Description of the Invention

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Components of the embodiments of the present invention described and illustrated in the drawings here can be arranged and designed in various different configurations.

[0028] Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed present invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0029] Embodiment The present invention provides a welding positioning device for an aluminum alloy formwork used in building construction, as Figure 1 、 Figure 2 shown, which includes a base 1. The provided base 1 is a basic cement hardened platform or a steel frame structure. The base 1 has a relatively large operating plane, which can provide more operating space for the splicing operation of large-sized aluminum alloy formworks. A number of support frames 4 are installed on the base 1. The support frames 4 are rectangular metal frame structures, and the number of support frames 4 is at least 2. The support frames 4 can be translated along the X-axis or Y-axis on the base 1. When in use, ensuring that the relative position of one of the support frames 4 does not change, the other support frame 4 can be adjusted to move along the X-axis or Y-axis on the base 1 relative to the support frame 4 with an unchanged position, so as to adjust the splicing position or splicing angle of two spliced aluminum alloy formworks. Positioning platforms 3 are assembled on the surfaces of the support frames 4. The positioning platforms 3 are rectangular frame structures, and their materials are spliced by steel. Two rotating shafts 14 are installed on both sides of the positioning platform 3; the rotating shafts 14 and the positioning platform 3 are integrally formed by welding.

[0030] Two support seats 16 corresponding to the rotating shafts 14 one by one are installed on the side walls of the support frames 4. The support seats 16 and the support frames 4 are integrally formed by welding. Rotating grooves adapted to the rotating shafts 14 are opened at the tops of the two support seats 16. The bottom of the rotating groove is in a semi-circular arc shape, and notches communicating with the rotating groove are opened on the opposite side walls of the two support seats 16. In this way, it is possible to avoid the vertical end of the rotating groove from hindering the circular motion of the rotating shaft 14 in the rotating groove. Driving mechanisms for driving one of the two rotating shafts 14 to perform circular motion are installed on both sides of the support frames 4.

[0031] Both sides of the support frame 4 are equipped with limiting mechanisms, which are used to limit the rotating shaft 14 in the rotating groove; the limiting mechanisms are all connected to the driving mechanism in a transmission manner; when one of the limiting mechanisms limits the corresponding rotating shaft 14 in the rotating groove, the other limiting mechanism releases the limiting effect of the corresponding rotating shaft 14; in this way, the rotating shaft 14 located at one end of the positioning platform 3 can be prevented from falling off from the rotating groove when the rotating shaft 14 is rotating on the support seat 16. And the two limiting mechanisms are connected to the driving mechanism in a transmission manner. When the driving mechanism drives the rotating shaft 14 located at one end of the positioning platform 3 to rotate on the support seat 16, the rotating shaft 14 located at the other end of the positioning platform 3 moves out of the rotating groove, and the limiting mechanism located there releases the limit on the rotating shaft 14, ensuring the normal operation of the structure. Through the linkage of the driving mechanism and the limiting mechanism, the splicing angle of the aluminum alloy templates on the two positioning platforms 3 is changed, which is convenient for splicing aluminum alloy templates with complex multi-curved surfaces or special-shaped surfaces, and improves the processing efficiency.

[0032] A clamping mechanism for clamping the aluminum alloy template is provided on the positioning platform 3. The clamping mechanism is used to clamp both sides of the aluminum alloy template, or when the special-shaped aluminum alloy template has a groove, the clamping end of the clamping mechanism can be embedded in the groove to fix the special-shaped aluminum alloy template, thereby improving the clamping effect and range of the structure on the aluminum alloy template.

[0033] Preferably, the number of the driving mechanisms is 2, which can drive both sides of the rotating shaft and limit the position, thereby ensuring the stability of the positioning platform 3 when it is turned over on the support seat 16.

[0034] In some technical solutions of the present invention, the driving mechanism includes a sliding seat 6, which is in the shape of an elongated strip and has a rectangular cross section. Racks 7 are fixedly installed at both ends of the sliding seat 6 by bolts, and gear structures 701 meshing with the racks 7 are installed on the two rotating shafts. The gear structures 701 are half-toothed or whole gears. A guide groove is provided on the side wall of the support frame 4 along the extension direction of the positioning platform 3. The cross section of the guide groove is wedge-shaped. The sliding seat 6 is slidably arranged in the guide groove. A wedge-shaped strip welded to the bottom of the sliding seat 6 is installed. The wedge-shaped strip is adapted to the guide groove, so that the sliding seat 6 can avoid derailment when reciprocating on the support frame 4, thereby ensuring the stability of the structure during operation.

[0035] The bottom of the support frame 4 is provided with a connecting groove connected with the guide groove, and the connecting groove is a rectangular groove. A connecting block 23 connected with the sliding seat 6 is slidably provided in the connecting groove, and the connecting block 23 is fixedly connected with the sliding seat 6 by bolts or welding. A push rod structure 13 connected with the connecting block 23 is installed at the bottom of the support seat 16. The push rod structure 13 is a hydraulic push rod or an electric push rod. The push rod structure 13 can quickly adjust the deflection angle of the positioning platform 3 through the gear structure 701 and the rack 7, and in the process of adjusting the deflection angle of the positioning platform 3 through the gear structure 701 and the rack 7, the deflection angle of the positioning platform 3 is controllable. It prevents the operator from having to reciprocate and adjust the inclination angle of the aluminum alloy template after the transition deflection. The above structure enables the operator to more accurately judge the inclination angle of the aluminum alloy template during the operation, thereby improving the adjustment efficiency and accuracy.

[0036] In some technical solutions of the present invention, the limiting mechanism includes a limiting frame 8, and the limiting frame 8 is U-shaped as a whole.

[0037] The side wall of the support seat 16 is provided with two limit grooves, and the limit plates 9 are slidably arranged in the limit grooves. After the limit plates 9 pass through the limit grooves, their parts are placed in the rotating grooves, so that the limit plates 9 can partially seal the upper area of ​​the rotating grooves to prevent the problem of the rotating shaft 14 moving out of the rotating grooves. The limit plates 9 and the limit frame 8 are integrally formed by welding. Two sliding shafts 12 are installed on the side wall of the limit frame 8 away from the support seat 16. The sliding shafts 12 are optical axes, and the sliding shafts 12 and the limit frame 8 are integrally formed by welding. The outer side wall of the sliding shaft 12 is slidably provided with a connecting plate 10, and the side wall of the connecting plate 10 is provided with a through hole adapted to the sliding shaft 12. The connecting plate 10 is connected to the sliding seat 6 on the same side thereof through a rod body. The sliding shaft 12 is sleeved with a position adjustment spring 11, and the position adjustment spring 11 is located between the connecting plate 10 and the limit frame 8. The free end of the sliding shaft 12 is provided with a blocking ring 20.

[0038] Preferably, the sliding shaft 12 is provided to penetrate the limiting frame 8 and then be fixedly connected to the side wall of the supporting seat 16 .

[0039] The working process of synchronous movement of the driving mechanism and the limiting mechanism is; First, in the initial state, the telescopic end of the telescopic structure is placed in the body of the telescopic structure, the two racks 7 are respectively located on both sides of the two gear structures 701, and the racks 7 and their corresponding gear structures 701 are in a meshing state.

[0040] Secondly, one of the two limiting structures limits its corresponding rotating shaft 14 in the rotating groove, and the other limiting mechanism releases the limiting effect on its corresponding rotating shaft 14. When the telescopic end of the telescopic structure gradually moves out of its body, when the telescopic end of the telescopic structure pushes the sliding seat 6 to move horizontally to the right, the limiting plate 9 on the right side of the support frame 4 releases the limiting effect on the rotating shaft 14 located thereunder under the push of the sliding seat 6 and the positioning spring 11. The limiting plate 9 on the left side of the support frame 4 restricts the rotating shaft in this area under the action of the sliding seat 6 and the positioning spring 11, so that the rotating shaft is placed in the rotating groove. At this time, the positioning platform 3 rotates counterclockwise around the support seat 16 on the left side of the support frame 4, and the horizontal angle of the positioning platform 3 relative to the base 1 can be adjusted, that is, the deflection angle of the aluminum alloy template fixed on the positioning platform 3 is adjusted, so as to adapt to different angles required for the splicing of the aluminum alloy template. Finally, when the above splicing work is completed and the positioning platform 3 needs to be parallel to the support frame 4; it is necessary to gradually retract the telescopic end of the telescopic structure into its body. At this time, the telescopic end of the telescopic structure pushes the sliding seat 6 to move horizontally to the left, and the positioning platform 3 rotates clockwise around the support seat 16 on the left side of the support frame 4 relying on the rotating shaft 14 until the positioning platform 3 is parallel to the support frame 4, and then the telescopic end of the telescopic structure returns to its initial position.

[0041] When the positioning platform 3 needs to rotate around the support seat 16 on the right side of the support frame 4, the limiting plate 9 on the left side of the support frame 4 restricts the rotating shaft in this area in the rotating groove, and the limiting plate 9 on the right side of the support frame 4 releases the restriction on the rotating shaft 14 in this area. The telescopic structure pulls the sliding seat 6 to move horizontally to the left. In this way, the positioning platform 3 rotates clockwise around the support seat 16 on the right side of the support frame 4. When the positioning platform 3 rotates to a certain angle, if it is necessary to rotate the positioning platform 3 in the reverse direction, just gradually retract the telescopic end of the telescopic structure into its body, and the reverse operation of the positioning platform 3 can be completed. In this way, the above operations provide angle adjustment in different directions for the splicing operation of the aluminum alloy template, improving the flexibility of this structure during the splicing of the aluminum alloy template.

[0042] In some technical solutions of the present invention, an operating platform 2 is installed on the positioning platform 3. The operating platform 2 is used to place and carry the aluminum alloy formwork, playing a role in protecting the overall structure and extending the service life of this structure. The positioning platform 3 is provided with an adjusting mechanism for adjusting the horizontal height of the positioning platform 3. The adjusting mechanism can finely adjust the horizontal height of the operating platform 2, so as to finely control the change in the splicing angle during the splicing of the aluminum alloy formwork. Ensure the splicing accuracy and splicing efficiency of this structure for the aluminum alloy formwork. The clamping mechanism is installed in the operating platform 2. It can better clamp the aluminum alloy formwork with complex curved surfaces, improve the clamping effect of this structure on the aluminum alloy formwork, and increase the applicable range of this structure.

[0043] In some technical solutions of the present invention, the clamping mechanism includes two V-shaped chutes 201 opened on the side walls of the operating platform 2, and the inner angles of the two chutes 201 are arranged oppositely. Two clamping parts 5 are slidably arranged in each of the chutes 201. Grooves are opened on the inner walls of the chutes 201. A limiting ring is rotatably arranged on the outer side wall of the clamping part 5, and a part of the limiting ring is embedded in the groove. On the opposite side walls of the operating platform 2 and the positioning platform 3, two paired connecting frames 18 are installed. Adjusting arms 17 are rotatably arranged at both ends of the connecting frame 18. The adjusting arm 17 is rotatably connected to the clamping part 5 on the same side as it. A two-way electric push rod 19 is installed on the operating platform 2. The two connecting frames 18 are respectively connected to the two telescopic ends of the two-way electric push rod 19. After the telescopic end of the two-way electric push rod 19 gradually moves out of the body of the two-way electric push rod 19, the connecting frame 18 pushes the clamping part 5 to move in the two vertical sections of the chute through the adjusting arm 17, so as to clamp parts with different width dimensions. And the parts can be placed on the operating platform 2 along the X-axis or Y-axis, providing a multi-angle fixing solution for the fixation of the aluminum alloy formwork and improving the fixing effect of this structure on the aluminum alloy formwork.

[0044] Preferably, the adjusting arm 17 is rotatably connected to the clamping part 5 on the same side as it through a ratchet structure.

[0045] The specific structure of the clamping part 5 includes a first clamping groove 501 and a second clamping groove 502 opened on the body of the clamping part 5. The first clamping groove 501 and the second clamping groove 502 are perpendicular to each other. The set clamping part 5 is prism-shaped as a whole, preferably a pentagonal prism. And 4 mounting grooves are circumferentially opened on the outer side wall of the clamping part 5, and an inflatable airbag 503 is installed in each mounting groove. A top plate 504 is installed on the telescopic end of the inflatable airbag 503. Thus, when the above structure needs to clamp an aluminum alloy template part with a groove space or a special-shaped space, the whole clamping part 5 can be embedded into the groove on the back of the aluminum alloy, and then the inflatable airbag 503 is inflated to make it expand. Subsequently, the top plate 504 is pushed to approach the inner wall of the aluminum alloy template, the clamping part 5 is placed in the groove, and a pulling force is applied to the clamping part 5 through the bidirectional electric push rod 19, so as to limit and fix the corresponding aluminum alloy template, increase the contact surface between the aluminum alloy template and the clamping part 5, and improve the clamping effect of the above structure on the aluminum alloy template.

[0046] Preferably, an inflation device communicated with the inflatable airbag 503 is installed on the support frame.

[0047] Preferably, the set first clamping groove 501 and the second clamping groove 502 can be adapted to the edges of the aluminum alloy template. When clamping the aluminum alloy template through the clamping structure, the clamping effect of the above structure on the aluminum alloy template can be improved.

[0048] In some technical solutions of the present invention, the two vertical sections of the chute are arc-shaped, and the outer circumferences of the circles where the two vertical sections are located intersect.

[0049] In some technical solutions of the present invention, the adjusting mechanism includes a telescopic rod installed on the positioning platform 3. The telescopic rod is an electric telescopic rod or a hydraulic telescopic rod. The telescopic end of the telescopic rod is fixedly connected to the operating platform 2 through bolts. A plurality of guide cylinders 301 are installed on the positioning platform 3, and guide rods 302 are slidably arranged in the guide cylinders 301. The guide rods 302 are connected to the operating platform 2. Thus, the adjusting mechanism can finely adjust the horizontal height of the operating platform 2, so as to control the splicing angle when splicing the aluminum alloy template by this structure. Ensure the splicing accuracy and splicing efficiency of this structure when splicing the aluminum alloy template. The cooperation of the set guide cylinder and the guide rod 302 can provide support for the operating platform 2, avoid the problem that a certain part of the operating platform 2 is stressed too much and affects the bearing effect of this structure, and prevent the aluminum alloy template fixed on the operating platform 2 from deflecting and tilting after the operating platform 2 tilts relative to the positioning platform 3, resulting in the docking accuracy of two aluminum alloy templates that need to be docked with each other not being guaranteed.

[0050] In some technical solutions of the present invention, a plurality of first adjustment grooves 101 are provided on the side wall of the base 1 along its extension direction, and a second adjustment groove 102 connected to the first adjustment groove 101 is provided on the side wall of the base 1 along its width direction, any first adjustment groove 101 and any second adjustment groove 102 are perpendicular to each other, the cross-sections of the first adjustment groove 101 and the second adjustment groove 102 are both rectangular, and the first adjustment groove 101 and the second adjustment groove 102 can be replaced by a "匚"-shaped channel steel. A walking mechanism adapted to the first adjustment groove 101 or the second adjustment groove 102 is installed on the support frame 4. The walking mechanism can ensure that the above structure can be adjusted in position on the base 1, ensure that the adjustment accuracy of the structure during the splicing of the aluminum alloy formwork can be fine-tuned, and ensure the efficiency of the splicing of the aluminum alloy formwork.

[0051] In some technical solutions of the present invention, the walking mechanism includes a plurality of supporting legs 22 installed at the bottom of the support frame 4, and the ends of the supporting legs 22 are all installed with walking seats, and the bottom of the walking seats are all rotating spherical walking wheels 21. The walking seats are partially embedded in the first adjustment groove 101 or the second adjustment groove 102, and the bottom of the walking wheel 21 is in contact with the bottom of the first adjustment groove 101 or the second adjustment groove 102. The groove widths of the first adjustment groove 101 and the second adjustment groove 102 are equal. The cross section of the walking seat is adapted to the groove width of the first adjustment groove 101 or the second adjustment groove 102, which avoids the problem of deflection of the walking seat when it moves in the first adjustment groove 101 or the second adjustment groove 102, and improves the stability of the present structure during operation. The spherical walking wheel 21 can avoid the increase of friction when the walking wheel 21 contacts the first adjustment groove 101 or the second adjustment groove 102, thereby improving its service life.
