Description

Technical Field

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

[0002] Aluminum profiles are metal materials with various cross-sectional shapes obtained by processing aluminum and aluminum alloys through processes such as extrusion, stretching, and molding. They are widely used in modern manufacturing due to their advantages such as light weight, high strength, corrosion resistance, ease of processing, and aesthetics. Aluminum profiles also have good plasticity and can be formed into different cross-sectional shapes through processes such as extrusion, molding, and stamping to meet various engineering needs. In specific applications, they are often used to meet specific dimensional requirements in various fields such as construction, manufacturing, and engineering.

[0003] When cutting or welding aluminum alloy formwork, due to its sharpness and heavy weight, manual operation is difficult. Therefore, a positioning device is required to secure it so that it can be processed more easily. However, existing positioning devices for aluminum alloy formwork processing and positioning for construction projects have certain drawbacks. First, the deflection angle of existing positioning devices for aluminum alloy formwork processing and positioning for construction projects is limited. In actual use, the interface between aluminum profiles or between an aluminum profile and another structure needs to be in a vertical or horizontal inclined state. In other words, the cross-sectional styles of aluminum profiles are diverse, and existing positioning devices have difficulty deflecting and combining the corresponding aluminum alloy formwork to form different shapes after splicing. Furthermore, existing positioning devices for aluminum alloy formwork processing and positioning for construction projects often clamp both sides of the part to be processed, which cannot fully secure aluminum alloy formwork with irregular surfaces or protrusions or grooves. As a result, the scope of application of common fixing equipment is very limited, resulting in the lack of guaranteed splicing accuracy of the aluminum alloy formwork. Summary of the Invention

DETAILED DESCRIPTION

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0039] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0040] Example

[0041] The present invention provides a welding positioning device for aluminum alloy templates used in construction, such as Figure 1 、 Figure 2 As shown, the structure comprises a base 1, which is a cement-hardened platform or a steel frame structure. The base 1 has a large operating surface, providing more space for assembling large-sized aluminum alloy formwork. Mounted on the base 1 are several support frames 4, each of which is a rectangular metal frame structure. There are at least two support frames 4. The support frames 4 can be translated along the X-axis or Y-axis on the base 1. During use, the relative position of one support frame 4 remains unchanged, while the other support frame 4 can be adjusted relative to the unchanged support frame 4 along the X-axis or Y-axis on the base 1 to adjust the splicing position or angle of the two joined aluminum alloy formworks. Each support frame 4 is fitted with a positioning platform 3, a rectangular frame structure made of spliced ​​steel. Two rotating shafts 14 are mounted on either side of the positioning platform 3; the rotating shafts 14 are integrally welded to the positioning platform 3.

[0042] Mounted on the side walls of the support frame 4 are two support bases 16, each corresponding one-to-one with the rotating shaft 14. The support bases 16 and the support frame 4 are integrally formed by welding. Each support base 16 has a rotation groove at its top that mates with the rotating shaft 14. The bottom of the rotation groove is semi-arc-shaped, and notches are provided on the opposing side walls of each support base 16, connecting to the rotation groove. This prevents the vertical ends of the rotation groove from obstructing the circular motion of the rotating shaft 14 within the rotation groove. A drive mechanism is mounted on each side of the support frame 4 to drive one of the two rotating shafts 14 into circular motion.

[0043] Both sides of the support frame 4 are equipped with limiting mechanisms, which are used to limit the rotating shaft 14 within the rotating groove. The limiting mechanisms are both transmission-connected to the driving mechanism. When one limiting mechanism limits its corresponding rotating shaft 14 within the rotating groove, the other limiting mechanism releases the limiting effect on its corresponding rotating shaft 14. This prevents the rotating shaft 14 on one end of the positioning platform 3 from falling out of the rotating groove when rotating on the support seat 16. Both limiting mechanisms are transmission-connected to the driving mechanism. When the driving mechanism drives the rotating shaft 14 on one end of the positioning platform 3 to rotate on the support seat 16, the rotating shaft 14 on the other end of the positioning platform 3 moves out of the rotating groove, and the limiting mechanism at that location releases the limiting effect on the rotating shaft 14, ensuring the normal operation of the structure. Through the linkage between the driving mechanism and the limiting mechanism, the splicing angle of the aluminum alloy templates on the two positioning platforms 3 is changed, facilitating the splicing of aluminum alloy templates with complex, multi-curved or irregular surfaces, and improving processing efficiency.

[0044] The positioning platform 3 is provided with a clamping mechanism for clamping the aluminum alloy template. The clamping mechanism is used to clamp both sides of the aluminum alloy template. When the special-shaped aluminum alloy template has a groove, the clamping end of the clamping mechanism can be inserted into 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.

[0045] Preferably, there are two driving mechanisms, 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 base 16.

[0046] 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 with a rectangular cross-section. Racks 7 are fixedly mounted on both ends of the sliding seat 6 by bolts. Gear structures 701 meshing with the racks 7 are mounted on both 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 guide groove has a wedge-shaped cross-section. 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 mounted. The wedge-shaped strip is adapted to fit the guide groove. This prevents the sliding seat 6 from derailing when reciprocating on the support frame 4, thereby ensuring the stability of the structure during operation.

[0047] The bottom of the support frame 4 is provided with a connecting groove connected to the guide groove, and the connecting groove is a rectangular groove. A connecting block 23 connected to the sliding seat 6 is slidably provided in the connecting groove, and the connecting block 23 is fixedly connected to the sliding seat 6 by bolts or welding. The bottom of the support seat 16 is installed with a push rod structure 13 connected to the connecting block 23. 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. This prevents the operator from having to adjust the inclination angle of the aluminum alloy template back and forth after the deflection is excessive. The above structure enables the operator to more accurately judge the inclination angle of the aluminum alloy template during operation, thereby improving the adjustment efficiency and accuracy.

[0048] 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.

[0049] The support base 16 has two retaining slots defined on its sidewalls. A retaining plate 9 slides within each slot. After penetrating the retaining slots, the retaining plate 9 partially rests on the rotation slot. This allows the retaining plate 9 to partially seal the upper portion of the rotation slot, preventing the rotating shaft 14 from moving out of the slot. The retaining plate 9 and the retaining frame 8 are integrally welded. Two sliding shafts 12 are mounted on the sidewall of the retaining frame 8 facing away from the support base 16. These sliding shafts 12 are optical axes and are integrally welded to the retaining frame 8. Connecting plates 10 slide on the outer sidewalls of the sliding shafts 12. The connecting plates 10 have through-holes adapted for the sliding shafts 12 defined in their sidewalls. The connecting plates 10 are connected to the sliding base 6 on the same side via a rod. An adjustment spring 11 is sleeved on the sliding shaft 12, located between the connecting plates 10 and the retaining frame 8. A blocking ring 20 is provided on the free end of the sliding shaft 12.

[0050] Preferably, the sliding shaft 12 is provided to pass through the limiting frame 8 and then fixedly connected to the side wall of the support seat 16 .

[0051] The working process of synchronous movement of the driving mechanism and the limiting mechanism is:

[0052] 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.

[0053] Secondly, one of the two limiting structures will limit the corresponding rotating shaft 14 within the rotation groove, and the other limiting mechanism will release the limiting effect of the corresponding rotating shaft 14. When the telescopic end of the telescopic structure gradually moves out of its main body, the telescopic end of the telescopic structure pushes the sliding seat 6 to move horizontally to the right. The limiting plate 9 located on the right side of the support frame 4, under the push of the sliding seat 6 and the adjustment spring 11, releases the limiting effect on the rotating shaft 14 located there. The limiting plate 9 located on the left side of the support frame 4, under the action of the sliding seat 6 and the adjustment spring 11, limits the rotating shaft located in this area, so that the rotating shaft is placed in the rotation groove. At this time, the positioning platform 3 rotates counterclockwise around the support seat 16 on the left side of the support frame 4, thereby adjusting the horizontal angle of the positioning platform 3 relative to the base 1, that is, adjusting the deflection angle of the aluminum alloy template fixed on the positioning platform 3, thereby adapting to the different angles adapted when the aluminum alloy template is spliced. Finally, when the above-mentioned splicing work is completed, the positioning platform 3 and the support frame 4 need to be kept parallel to each other; the telescopic end of the telescopic structure needs to be gradually retracted into its body. At this time, the telescopic end of the telescopic structure pushes the sliding seat 6 to move left in the horizontal direction, and the positioning platform 3 relies on the rotating shaft 14 to rotate clockwise around the support seat 16 on the left side of the support frame 4 until the positioning platform 3 and the support frame 4 remain parallel to each other, and the telescopic end of the telescopic structure returns to its initial position.

[0054] When the positioning platform 3 needs to rotate around the support seat 16 located on the right side of the support frame 4, the limit plate 9 located on the left side of the support frame 4 will limit the rotation axis located in this area to the rotation groove, and the limit plate 9 located on the right side of the support frame 4 will contact the limit of the rotation axis 14 located in this area, and the telescopic structure will pull the sliding seat 6 to move to the left in the horizontal direction. In this way, the positioning platform 3 will rotate clockwise around the support seat 16 on the right side of the support frame 4. After the positioning platform 3 rotates to a certain angle, the positioning platform 3 needs to be rotated in the opposite direction. The reverse operation of the positioning platform 3 can be completed by gradually retracting the telescopic end of the telescopic structure into its body. In this way, the above operation provides angle adjustment in different directions for the splicing operation of the aluminum alloy formwork, thereby improving the flexibility of this structure in splicing the aluminum alloy formwork.

[0055] 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 support the aluminum alloy formwork, which protects the overall structure and extends the service life of the structure. The positioning platform 3 is provided with an adjustment mechanism for adjusting the horizontal height of the positioning platform 3. The adjustment mechanism can fine-tune the horizontal height of the operating platform 2, so that the structure can finely control the change in splicing angle when splicing the aluminum alloy formwork. The splicing accuracy and splicing efficiency of the aluminum alloy formwork are guaranteed by this structure. The clamping mechanism is installed in the operating platform 2. It can better clamp the aluminum alloy formwork with complex curves, improve the clamping effect of the present structure on the aluminum alloy formwork, and increase the scope of application of the present structure.

[0056] In some technical solutions of the present invention, the clamping mechanism includes two V-shaped chutes 201 provided on the side walls of the operating platform 2, with the inner corners of the two chutes 201 arranged opposite to each other. Two clamping parts 5 are slidably provided in the chutes 201, and grooves are provided on the inner walls of the chutes 201. A limit ring is rotatably provided on the outer wall of the clamping part 5, and a part of the limit ring is embedded in the groove. Two connecting frames 18 are installed in pairs on the opposite side walls of the operating platform 2 and the positioning platform 3. Adjustment arms 17 are rotatably provided at both ends of the connecting frames 18. The adjustment arms 17 are rotatably connected to the clamping parts 5 on the same side as the two connecting frames 18. A bidirectional electric push rod 19 is installed on the operating platform 2, and the two connecting frames 18 are respectively connected to the two telescopic ends of the bidirectional electric push rod 19. The telescopic end of the bidirectional electric push rod 19 gradually moves out of the body of the bidirectional electric push rod 19, and the rear connecting frame 18 pushes the clamping part 5 to move in the two vertical sections of the slide groove through the adjusting arm 17, so that parts of different widths can be clamped, 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 template, thereby improving the fixing effect of this structure on the aluminum alloy template.

[0057] Preferably, the adjusting arm 17 is rotationally connected to the clamping portion 5 on the same side thereof via a ratchet structure.

[0058] The specific structure of the clamping portion 5 includes a first slot 501 and a second slot 502 formed on the main body of the clamping portion 5. The first slot 501 and the second slot 502 are perpendicular to each other. The clamping portion 5 is generally prismatic, preferably a pentagonal prism. Four mounting slots are formed around the outer wall of the clamping portion 5. Each mounting slot contains an inflatable airbag 503. A top plate 504 is mounted on the telescopic end of the inflatable airbag 503. Thus, when the above structure is required for an aluminum alloy formwork component having a recessed space or a special-shaped space, the clamping portion 5 can be entirely inserted into the recess on the back of the aluminum alloy. The inflatable airbag 503 is then inflated to expand, and the top plate 504 is then pushed toward the inner wall of the aluminum alloy formwork, placing the clamping portion 5 in the recess. A tension force is then applied to the clamping portion 5 by a bidirectional electric push rod 19, thereby securing the corresponding aluminum alloy formwork in place, increasing the contact surface between the aluminum alloy formwork and the clamping portion 5, and improving the clamping effect of the above structure on the aluminum alloy formwork.

[0059] Preferably, an inflation device connected to the inflatable airbag 503 is installed on the support frame.

[0060] Preferably, the first clamping groove 501 and the second clamping groove 502 can be adapted to the edges of the aluminum alloy template, and when the aluminum alloy template is clamped by the clamping structure, the clamping effect of the above structure on the aluminum alloy template can be improved.

[0061] 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.

[0062] In some technical solutions of the present invention, the adjustment mechanism includes a telescopic rod installed on the positioning platform 3, the telescopic rod being an electric telescopic rod or a hydraulic telescopic rod, the telescopic end of the telescopic rod being fixedly connected to the operating platform 2 by bolts, and a plurality of guide cylinders 301 being installed on the positioning platform 3, each of which is slidably provided with a guide rod 302, which is connected to the operating platform 2. In this way, the adjustment mechanism can fine-tune the horizontal height of the operating platform 2, thereby controlling the splicing angle of the structure when splicing the aluminum alloy templates. This ensures the precision and splicing efficiency of the structure when splicing the aluminum alloy templates. The cooperation between the provided guide cylinder and the guide rod 302 can provide support for the operating platform 2, preventing the operating platform 2 from being subjected to excessive force at a certain point and affecting the bearing effect of the structure. Furthermore, after the operating platform 2 tilts relative to the positioning platform 3, the aluminum alloy template fixed to the operating platform 2 deflects and tilts, causing the docking precision of two aluminum alloy templates that need to be docked to be not guaranteed.

[0063] 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 extending direction, and a second adjustment groove 102 communicating with the first adjustment groove 101 is provided on the side wall of the base 1 along its width direction. Any one of the first adjustment grooves 101 and any one of the second adjustment grooves 102 are perpendicular to each other. The cross-sections of the provided first adjustment grooves 101 and second adjustment grooves 102 are both rectangular, and the provided first adjustment grooves 101 and second adjustment grooves 102 can be replaced by channel steels in a "C" shape. A traveling mechanism adapted to the first adjustment groove 101 or the second adjustment groove 102 is installed on the support frame 4. The provided traveling mechanism can ensure that the above structure can be adjusted in position on the base 1, ensure that the adjustment accuracy during the splicing of the aluminum alloy template can be finely adjusted, and ensure the efficiency during the splicing of the aluminum alloy template.

[0064] In some technical solutions of the present invention, the traveling mechanism includes a plurality of support legs 22 installed at the bottom of the support frame 4. Traveling seats are installed at the ends of the support legs 22. Spherical traveling wheels 21 are rotatably installed at the bottoms of the traveling seats. A part of the traveling seats is embedded in the first adjustment groove 101 or the second adjustment groove 102, and the bottoms of the traveling wheels 21 are in contact with the bottoms 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 traveling seat is adapted to the groove width of the first adjustment groove 101 or the second adjustment groove 102, avoiding the problem of deflection when the traveling seat moves in the first adjustment groove 101 or the second adjustment groove 102, and improving the stability of the operation of this structure. The spherical traveling wheels 21 can avoid an increase in the frictional force when the traveling wheels 21 contact the first adjustment groove 101 or the second adjustment groove 102, and improve its service life.

[0065] A construction method of a welding positioning device for an aluminum alloy template used in building construction is as follows.

[0066] The support frame 4 moves in the first adjustment groove 101 and the second adjustment groove 102 of the base 1 through the traveling mechanism.

[0067] The support frame 4 controls the angular deflection of the positioning platform 3 through the cooperation of the driving mechanism and the limiting mechanism.

[0068] When the push rod structure 13 in the driving mechanism pushes the sliding seat 6 to move on the support frame 4, it drives the gear rack 7 to drive the rotating shaft 14 to rotate; at the same time, the limiting mechanism on one side of the support frame 4 restricts the rotating shaft on its same side, and the limiting mechanism on the other side of the support frame 4 releases the restriction on the rotating shaft on its same side, ensuring the stability during the single-sided rotation of the platform.

[0069] The driving mechanism and the limiting mechanism are linked to make the positioning platform 3 rotate clockwise or counterclockwise around the left or right side of the support frame 4.

[0070] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
