Description

Technical Field

[0001] This invention relates to the field of welding and processing of high-strength steel formwork for buildings, and in particular to a welding fixture for processing high-strength steel formwork for buildings. Background Technology

[0002] Construction steel formwork is a formwork system made of steel plates and shaped steel, used to cast concrete components to shape them and achieve the required design dimensions.

[0003] High-strength steel formwork has rapidly replaced aluminum alloy formwork due to its lower cost and superior quality. However, the production process of high-strength steel formwork requires numerous welding points, and manual welding is slow, severely hindering capacity expansion and product adoption. Therefore, most manufacturers have begun researching the use of robotic welding to increase production capacity.

[0004] Because construction formwork requires a high degree of flatness, more than a dozen components need to be precisely fixed in their welding positions before welding, with an error margin not exceeding 0.2 millimeters. This places significant demands on the fixing fixtures. Traditional pneumatic and mechanical pressure fixing requires numerous pressure devices to be placed on the workpiece surface. Furthermore, mechanical components are prone to collisions during welding, causing equipment damage and hindering mass production. Therefore, it is necessary to provide a new welding workbench for processing high-strength steel formwork for buildings to solve the above-mentioned technical problems. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the present invention provides a welding fixture for processing high-strength steel formwork for buildings.

[0006] The welding workbench for processing high-strength steel formwork for buildings provided by this invention includes: The machine platform is a cuboid shape adapted to the main body of the template frame, and its upper surface is the placement area; A mechanical positioning mechanism is installed on the upper part of the machine platform, and the mechanical positioning mechanism contacts and presses the template frame body in the horizontal direction to position the template frame body. A magnetic locking mechanism is installed at the lower end of the machine table surface and provides a main fixing force to the template frame body through a controllable magnetic attraction. The mechanical positioning mechanism locks the welding template assembly. The mechanical positioning mechanism locks the welding template assembly in two symmetrical sets, which are rotatably mounted on the machine base and can be precisely engaged with the template frame body.

[0007] Preferably, the upper part of the machine platform and near one side has an integrally connected protrusion, the protrusion being of the same length as the machine platform along its length. The upper part of the machine platform is also bolted with a stop corresponding to the protrusion, so that a groove is formed between the stop and the protrusion, and the groove is a placement area.

[0008] Preferably, a mechanical positioning mechanism is installed inside the groove and on the side of the protrusion facing the groove; Two sets of mechanical positioning mechanisms are provided inside the groove, and the two sets of mechanical positioning mechanisms are symmetrically arranged and far from the center of the groove, while multiple sets are linearly distributed on the side of the protrusion.

[0009] Preferably, the mechanical positioning mechanism includes a cylinder, the cylinder is bolted to the machine base protrusion, and a pressure plate is welded and fixed to the output end of the cylinder; In the two sets of mechanical positioning mechanisms located inside the groove, the pressure plates in both exert symmetrical pressure on the template frame body, while in the mechanical positioning mechanism located on the protrusion, the pressure plate cooperates with the stop to exert pressure on the template frame body.

[0010] Preferably, the top of the mechanical positioning mechanism does not exceed the protrusion and the stop in the vertical direction.

[0011] Preferably, the magnetic locking mechanism is an electromagnet, and the machine base is provided with a power supply to power the electromagnet and a switch to control the opening and closing of the electromagnet.

[0012] Preferably, the mechanical positioning mechanism for locking the welding template assembly includes a bracket, the bracket having an L-shaped cross-section, and two sets of brackets being mounted on the protrusion and the stop respectively via hinges, and the brackets being able to engage or disengage with the template frame body by rotation; Multiple openings corresponding to the welding points of the template frame body are provided on the long end plate of the card holder, while multiple locking slots for fastening with the template frame body are provided on the short end end face.

[0013] Preferably, the template frame body includes a U-shaped outer frame, the outer frame having two support rods welded and fixed along its length, and multiple horizontal bars along the width of the outer frame mounted on the support rods, the two ends of the horizontal bars being welded and fixed to the outer frame.

[0014] Preferably, the window corresponds to the welding area between the outer frame and the crossbar, and the crossbar can be embedded inside the locking slot.

[0015] Compared with related technologies, the welding workbench for processing high-strength steel formwork for buildings provided by the present invention has the following beneficial effects: By utilizing the adsorption principle of strong electromagnets, strong electromagnets are arranged under the workbench according to the pressure requirements. The high-strength steel template is placed on the workbench. Before welding, the magnets are turned on to attract and fix the welding parts. After successful welding, the power is turned off and the welded product is removed, thus realizing safe welding operation on the template frame. The cylinder drives the pressure plate to move, thereby pushing the entire template frame body to move. This allows for the movement of the template frame body's position, enabling automated adjustment of its position and further improving processing efficiency. The mechanical positioning mechanism locks the welding template assembly, which can clamp the template frame body. After the clamping is completed, it can achieve high-precision positioning of the template frame body, and at the same time, it can position the outer frame and crossbar in the template frame body, which is more conducive to the subsequent welding processing between the outer frame and crossbar. The clamp also has openings for corresponding welding points, so it will not affect the welding processing between the outer frame and crossbar of the welding device. Attached Figure Description

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0019] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0020] Please see Figures 1 to 6 The present invention provides a welding fixture for processing high-strength steel formwork for buildings. The welding workbench for processing high-strength steel formwork for buildings includes a machine base 1, a mechanical positioning mechanism 2, a magnetic locking mechanism 3, a mechanical positioning mechanism for locking welding formwork components 4, and a formwork frame body 5.

[0021] For machine 1; Please see Figure 4 and Figure 6 The machine base 1 is a cuboid shape that adapts to the template frame body 5, and its upper surface is the placement area; The upper end of the machine base 1 and near one side has an integrally connected protrusion 11, which is the same length as the machine base 1 along the length direction of the machine base 1. The upper end of the machine base 1 is also bolted with a stop 12 corresponding to the protrusion 11, so that a groove is formed between the stop 12 and the protrusion 11, and the groove is the placement area; The template frame body 5 is placed inside the groove of the machine base 1. The template frame body 5 includes a U-shaped outer frame 51. The outer frame 51 is welded and fixed with two support rods 52 along the length direction. Multiple crossbars 53 along the width direction of the outer frame 51 are mounted on the support rods 52. The two ends of the crossbars 53 are welded and fixed to the outer frame 51.

[0022] It should be noted that: the machine base 1 is the basic structure of the entire device. It is rectangular in shape and has enough space inside to install the drive source required for the entire device (including the starting device and the power supply device, which are not shown in the figure). The upper end of the machine base 1 is provided with a protrusion 11 and a baffle 12. The two are symmetrically arranged and form a groove structure between them. This groove structure is used to place the template frame body 5. If the template frame body 5 is initially placed in the groove structure, it can limit the main range and facilitate the precise adjustment of the position of the template frame body 5 in the future. The main body 5 of the template frame is a traditional template frame, and the welding point targeted in this case is the welding between the outer frame 51 and the crossbar 53.

[0023] For mechanical positioning mechanism 2; Please see Figure 4 Mechanical positioning mechanisms 2 are installed inside the groove and on the side of the protrusion 11 facing the groove. Among them, two sets are set inside the groove, and the two sets of mechanical positioning mechanisms 2 are symmetrically arranged and far away from the center of the groove, while multiple sets are linearly distributed on the side of the protrusion 11. That is, the mechanical positioning mechanism 2 includes a cylinder 21, which is bolted to the machine base 1\protrusion 11, and a pressure plate 22 is welded and fixed to the output end of the cylinder 21. In the two sets of mechanical positioning mechanisms 2 located inside the groove, the pressure plate 22 in both exerts symmetrical pressure on the template frame body 5, while in the mechanical positioning mechanism 2 located on the protrusion 11, the pressure plate 22 cooperates with the baffle 12 to exert pressure on the template frame body 5. Among them, the top of the mechanical positioning mechanism 2 does not exceed the protrusion 11 and the stop 12 in the vertical direction.

[0024] It should be noted that the mechanical positioning mechanism 2 is the main positioning structure of the template frame body 5. By adjusting the position of the template frame body 5, the correspondence between the template frame body 5 and the mechanical positioning mechanism locking welding template assembly 4 is more accurate, which is beneficial for subsequent high-precision welding operations on the template frame body 5. Regarding the quantity and distribution of the mechanical positioning mechanism 2, there are two sets symmetrically arranged inside the groove, and multiple sets linearly distributed on the side of the protrusion 11. Its structure includes a cylinder 21 and a pressure plate 22 installed at the output end of the cylinder 21. When positioning the template frame body 5, the cylinder 21 on the side of the protrusion 11 is first activated, causing the pressure plate 22 at its output end to contact the outer frame 51. The pressure generated on the outer frame 51 causes the entire template frame body 5 to move towards the position of the stop frame 12 until one side of the template frame body 5 contacts the stop frame 12. Then, the pressure of the pressure plate 22 on the cylinder 21 is removed, and the cylinder 21 located inside the groove is activated. The two symmetrically arranged pressure plates 22 achieve the squeezing adjustment of the template frame body 5, realizing the precise adjustment of the position of the template frame body 5. After the adjustment is completed, the cylinder 21 on the side of the protrusion 11 is activated again, causing the pressure plate 22 on it to squeeze the template frame body 5 again, which can play a preliminary fixing role for the template frame body 5. Each set of mechanical positioning mechanisms 2 is located inside the groove, and its height does not exceed the depth of the groove. Therefore, after the initial positioning of the template frame body 5 is completed, there is basically no structure above it for positioning and fixing. Therefore, when the outer frame 51 and crossbar 53 in the template frame body 5 are welded and fixed in the subsequent process, the welding equipment will not be hindered by other structures, thus achieving efficient and safe welding processing of the template frame body 5.

[0025] For magnetic locking mechanism 3; Please see Figure 4 The magnetic locking mechanism 3 is an electromagnet. The machine base 1 is equipped with a power supply to power the electromagnet and a switch to control the opening and closing of the electromagnet.

[0026] It should be noted that the magnetic locking mechanism 3 is the main fixing structure. It is an electromagnet. The area where the template frame body 5 is placed is within the range of the electromagnet's action. That is, after the template frame body 5 is positioned, it can be magnetically fixed by the electromagnet. The positioning structure is located on the upper part of the machine base 1 and below the template frame body 5. Therefore, when fixing the template frame body 5, it does not have a structure above the template frame body 5, which makes the fixing of the template frame body 5 more flexible and will not have any impact on the subsequent welding process.

[0027] For the mechanical positioning mechanism to lock the welding template assembly 4; Please see Figure 5 The mechanical positioning mechanism locks the welding template assembly 4, which includes a card holder 41. The card holder 41 has an L-shaped cross section. Two sets of card holders 41 are respectively installed on the protrusion 11 and the stop 12 via hinges. The card holder 41 can be engaged or disengaged from the template frame body 5 by rotation. Multiple openings 42 corresponding to the welding points of the template frame body 5 are provided on the long end plate of the card holder 41, while multiple locking slots 43 are provided on the short end end face to achieve engagement with the crossbar 53 in the template frame body 5.

[0028] It should be noted that the positioning of the template frame body 5 requires the use of a mechanical positioning mechanism to lock the welded template assembly 4. That is, because the mechanical positioning mechanism locks the welded template assembly 4 and the template frame body 5 together, the positioning of the template frame body 5 must ensure that the template frame body 5 and the mechanical positioning mechanism lock the welded template assembly 4 can be locked together with high precision, i.e., the optimal position of the template frame body 5. Only then can the template frame body 5 be fixed by an electromagnet. For the mechanical positioning mechanism locking welding template assembly 4, its card holder 41 is the main structure. The cross-section of the card holder 41 is L-shaped. Its long end plate is installed on the protrusion 11 or the stop 12 by a hinge, so that it can rotate in the vertical direction. The card holder 41 is engaged or disengaged from the template frame body 5 by its own rotation adjustment. The card holder 41 has a window 42 and a locking slot 43. When the card holder 41 and the template frame body 5 are engaged, the window 42 precisely corresponds to the welding point of the outer frame 51 and the crossbar 53. Therefore, the welding equipment can pass through the window 42 to perform welding processing on the outer frame 51 and the crossbar 53. At the same time, the crossbar 53 is embedded in the locking slot 43. At this time, the crossbar 53 can be restricted so that it can be precisely positioned on the outer frame 51, ensuring the accuracy of the welding position.

[0029] The specific operating procedure for this device is as follows: First, the template frame body 5 is hoisted or placed in the groove formed by the protrusion 11 and the stop 12 at the upper end of the machine base 1. The groove structure provides initial lateral limitation for the template frame body 5, ensuring that it is within a roughly correct working range.

[0030] Multiple sets of mechanical positioning mechanisms 2 installed on the side of the protrusion 11 are activated. These cylinders 21 operate synchronously, driving the pressure plates 22 at their output ends to apply pressure to the outer frame 51, pushing the entire template frame body 5 to move laterally until one side of it is tightly against the opposite side of the retaining frame 12. This step, using the retaining frame 12 as a reference, completes the coarse positioning of the template frame body 5 in the width direction.

[0031] After coarse positioning, the cylinder 21 on the side of the protrusion 11 retracts, and the pressure plate 22 separates from the template frame body 5. Then, two sets of mechanical positioning mechanisms 2 symmetrically positioned at the bottom of the groove are activated. Their cylinders 21 drive the pressure plate 22 to symmetrically press the outer frame 51 of the template frame body 5 from both sides, fine-tuning it until it is precisely centered within the groove. This position ensures that the template frame body 5 is accurately aligned with the subsequent mechanical positioning mechanism locking and welding template assembly 4. After precise positioning, the mechanical positioning mechanism 2 on the side of the protrusion 11 is activated again, causing the pressure plate 22 to press against the template frame body 5, initially clamping and fixing it.

[0032] Then, the mechanical positioning mechanisms on both sides lock the welding template assembly 4 and rotate it to the closed position. The L-shaped bracket 41 rotates downward through the hinge, so that the locking slot 43 on its short end is precisely engaged with the crossbar 53 of the template frame body 5. At the same time, downward pressure is applied to the crossbar 53 to ensure that it is stably mounted on the support rod 52. Thus, the positioning of the template frame body 5 is completed. (If the bracket 41 cannot be precisely engaged with the template frame body 5, then the position of the template frame body 5 needs to be adjusted to ensure that the two are precisely engaged.)

[0033] Next, the magnetic locking mechanism 3 (i.e., electromagnet) is activated. Under the action of magnetic force, the entire template frame body 5 is firmly attracted and fixed on the placement surface of the machine base 1, so that the template frame body 5 is in a stable state.

[0034] After all locking steps are completed, the welding equipment can precisely weld the exposed welding points of the outer frame 51 and the crossbar 53 through the opening 42 precisely cut into the long end plate of the clamp 41. Throughout the process, all positioning and locking mechanisms are located below or to the side of the workpiece, and the welding path is unobstructed, thus achieving safe, efficient, and high-quality automated welding.

[0035] After welding is completed, first close the magnetic locking mechanism 3 to release the magnetic force, then open and rotate the mechanical positioning mechanism to lock the welding template assembly 4 to separate it from the workpiece, and finally remove the pressure plates 22 of all mechanical positioning mechanisms 2. The welded integrated template frame body 5 can then be lifted off the machine base 1, and the equipment is ready to start the next work cycle.

[0036] The above are merely embodiments of the present invention and do not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
