Description

Technical Field

[0001] The invention relates to the technical field of door and window aluminum frame welding auxiliary technology, in particular to an auxiliary device for door and window aluminum frame welding. Background Art

[0002] Aluminum frames for doors and windows are a common frame structure used in modern building doors and windows. The material characteristics are light: the density of aluminum is relatively low, which makes the aluminum frames for doors and windows light, easy to install and carry, and also reduces the overall weight of the building. High strength: through reasonable design and processing technology, such as using aluminum alloy materials and performing heat treatment, cold processing, etc., the aluminum frames for doors and windows can have higher strength, can withstand certain external forces and self-weight, and ensure the stability and safety of doors and windows. Corrosion resistance: Aluminum easily reacts with oxygen in the air to form a dense aluminum oxide film. This oxide film can prevent further oxidation of the internal aluminum, making it have good corrosion resistance, suitable for various environments, and prolonging the service life of doors and windows. Good machinability: Aluminum has good plasticity and machinability, and is easy to be processed into aluminum frames for doors and windows of various shapes and sizes through extrusion, cutting, drilling, welding and other processes to meet different architectural styles and design requirements. Good thermal conductivity and electrical conductivity: Aluminum has good thermal and electrical conductivity. Aluminum frames for doors and windows have been widely used and developed in the field of building doors and windows with its excellent material properties, diverse structural forms, advanced manufacturing processes and wide application advantages.

[0003] The welding of aluminum frames for doors and windows is a process of welding aluminum alloy profiles into aluminum frames for doors and windows. In this process, due to the light weight and thinness of aluminum alloy profiles, the shape of the aluminum frame may change due to various reasons during operation, and deformations such as bending and twisting may occur, as well as slag or other impurities may splash, which will affect the welding yield. Therefore, the welding operators are required to have rich welding experience and professional knowledge. The existing welding operations for aluminum frames for doors and windows are usually carried out on concrete floors or stainless steel supports. Although the welding slag generated by welding is relatively easy to clean, as the operation proceeds, welding slag will accumulate at the operation position and require regular cleaning, which will affect the operation. In the corresponding small aluminum frame welding operations, fixed splicing is inconvenient and cannot meet various fixing requirements. In addition, the smoke generated by welding will affect the observation of operators, thereby affecting the welding process. Therefore, there is a lack of welding auxiliary devices. Based on this, an auxiliary device for welding aluminum frames for doors and windows is proposed. Summary of the invention

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: the device is provided with a threaded mounting frame and a hollow rod. After the door and window aluminum frame is placed, the middle-shaped arc slider is arranged inside the middle-shaped arc slide groove and the position of the threaded mounting frame is rotated to surround the outer side of the door and window aluminum frame. The threaded pushing action of the hollow rod and the threaded strip and the inner wall of the threaded mounting frame causes the spring telescopic column and the rubber clamping head to clamp the outer side of the door and window aluminum frame. The elastic deformation of the spring telescopic column stabilizes the clamping of the outer side of the door and window aluminum frame, thereby facilitating the welding clamping operation requirements of most door and window aluminum frame workpieces, facilitating rotation adjustment, and after the rotation adjustment, the relative position of the middle-shaped arc slider is fixed by clamping the mounting bolts and the clamping plate, thereby facilitating adjustment, realizing both clamping operation and supporting the inner wall, thereby increasing the stable clamping of the door and window aluminum frame, so as to adapt to the clamping and positioning operations of various small door and window aluminum frames;

The power socket is externally connected to a power plug. When the suction fan is started, an airflow is generated downward. The aluminum frame of doors and windows is welded on the top of the middle mounting plate. The generated welding slag falls on the top of the top support net. A part of the fine welding slag falls on the top of the filter paper disc through the top support net. With the downward flow of air, the smoke generated during welding is guided to the inside of the bottom mounting frame through the airflow, and part of the smoke particles are adsorbed by the filter paper disc, thereby reducing the impact on the sight of the operator and increasing the safety of welding.

[0017] The present invention facilitates stabilizing the position of the top support net by supporting the top support net through the magnet head and the installation notch, so that during the welding process of the aluminum frame of the door and window, the welding slag generated falls on the top of the top support net, and after accumulating for a certain period of time, the top support net is removed to remove and clean the welding slag, which is convenient for cleaning, reduces the influence of welding slag accumulation on the operation, and increases the convenience of the overall operation;

It is convenient to sleeve the outer side of the threaded mounting frame through the mounting concave frame, and invert the threaded mounting frame so that the bolts are inserted into the connecting seat and the connecting hole to fix the position of the threaded mounting frame, thereby facilitating the rotation and adjustment of the threaded mounting frame. After rotating the clamping and pushing direction of the threaded mounting frame, the positioning bolts are tightened into the docking hole, which is convenient for rotation adjustment at a required angle, and convenient for increasing the rotation clamping direction of the threaded mounting frame, thereby further facilitating the clamping operation of the special-shaped parts of the door and window aluminum frame and ensuring the stability of the structure.

[0032] The working principle of the above technical solution is as follows: when in use, the operator places the aluminum frame of the door and window to be welded on the top of the middle mounting plate 6, and rotates the hollow rod 503, thereby pushing the hollow rod 503 and the clamping block mounting frame 508 to move under the threaded connection between the threaded strip 501 and the inner wall of the threaded mounting frame 5, thereby prompting the rubber clamping head 507 to contact the outer side of the door and window aluminum frame, and then slide a set of threaded mounting frames 5 and the middle arc slider 4 to the opening position of the door and window aluminum frame, rotate the hollow rod 503 to prompt the clamping block mounting frame 508 and the inner support clamping plate 509 to extend into the inner wall of the door and window aluminum frame, and then rotate the bolt head 504 and the support rod 511 and rotate them under the rotation support of the rotating plate 525 and the rotating ring 524, so that the limit clamping column 522 is in contact with the two The opening positions of the half ring blocks 521 are flush, and then the bolt head 504 and the support rod 511 are pushed. The support rod 511 pushes the rotating ring 524 and the push rod 523 to move, and the push rod 523 pushes the installation tube 514 to move, and then pushes the hinged hinge slot plate 1 515, the hinge mounting seat 1 516 and the hinge mounting seat 2 517, and the bottom limit support plate 512 is limited by the inner wall of the clamping block mounting frame 508, so that the hinge slot plate 1 515 is changed from inclined to upright, and then pushes the bottom limit support plate 512 and the inner support splint 509 to move outward, and then makes the inner support splint 509 contact with the inner wall of the door and window aluminum frame, forming an inner wall support frame state for the door and window aluminum frame, avoiding soft collapse during welding, and increasing the support of the inner wall.

[0033] In another embodiment, Figure 1-Figure 6 As shown, the arc-shaped mounting frame 8 is arc-shaped and is evenly distributed on the bottom of the support platform 1 and the middle mounting plate 6 in a circumferential manner. The middle arc slider 4 is evenly distributed on the inner side of the middle arc slide groove 3 in a circumferential manner. A clamping plate 403 is movably installed on the bottom of the middle arc slider 4. A mounting bolt 402 is movably inserted on the inner side of the clamping plate 403. The mounting bolt 402 movably penetrates the clamping plate 403 and extends to the inside of the bottom end of the middle arc slider 4 through a thread.

[0034] The arc-shaped mounting frame 8 provides stable support for the connection between the support platform 1 and the middle mounting plate 6, and increases the stability of the structure. The middle arc slider 4 and the middle arc slide groove 3 slide stably, which is convenient for stable movement and adjustment of the position on the inside.

Through the threaded pushing action of the hollow rod 503 and the threaded strip 501 and the inner wall of the threaded mounting frame 5, the spring telescopic column 506 and the rubber clamping head 507 are clamped on the outer side of the door and window aluminum frame.

[0042] Through the setting of the bottom mounting frame 7, during the process of welding the aluminum frame of doors and windows, the filter paper disc 10 and the magnet ring 11 are inserted into the inner side of the bottom mounting frame 7 through the semi-ring insertion groove 706, and are placed on the top of the hollow support net 702, and the power socket 704 is connected to an external power plug. When the suction fan 703 is started, a downward airflow is generated, and the aluminum frame of doors and windows is welded on the top of the middle mounting disc 6. The welding slag that appears falls on the top of the top support net 601, and a part of the fine welding slag falls on the top of the filter paper disc 10 through the top support net 601. As the airflow goes downward, the smoke generated during welding is guided to the inside of the bottom mounting frame 7 through the airflow, and some smoke particles are adsorbed by the filter paper disc 10, thereby reducing the impact on the operator's line of sight and increasing the safety of welding.

[0043] In another embodiment, Figure 1-Figure 7 As shown, the material of the inner support plate 509 is one of pure copper, graphite and ceramic, and the material of the hollow support net 702 and the top support net 601 are both stainless steel.

[0044] The inner support plate 509 provides internal support for the inner wall of the aluminum frame of the door and window during the welding process to prevent the aluminum frame of the door and window from collapsing, and the molten aluminum frame of the door and window will contact the inner support plate 509. Pure copper has good thermal conductivity and can quickly conduct the heat generated during the welding process, reducing the accumulation of heat in the supporting parts, thereby reducing the possibility of adhesion. At the same time, the surface of copper is relatively smooth and is not easy to react excessively with aluminum at high temperature during welding and cause adhesion. Graphite has the characteristics of high temperature resistance, good thermal conductivity, and high chemical stability. During the welding process, graphite can withstand high temperatures without melting or deformation, and its surface is not easy to adhere to aluminum. Even in a long-term high-temperature welding environment, it can maintain good separation. Ceramic material has an extremely high melting point and good chemical stability. It will not react chemically with aluminum and adhere to it under high welding temperatures, ensuring welding safety. In order to avoid the possibility of adhesion between the inner support splint 509 and the inner wall of the door and window aluminum frame, it is convenient for auxiliary operations. The stainless steel material of the hollow support net 702 and the top support net 601 also reduces the possibility of adhesion and provides good thermal conductivity for the welding slag. It is also convenient for subsequent cleaning after the welding slag falls, and indirectly increases the service life.

[0045] In another embodiment, Figure 1 , Figure 3 , Figure 4 , Figure 5 and Fig. 9 As shown, a bearing support 902 is fixedly installed on the top of the auxiliary mounting seat 9, and a plurality of docking holes 901 are opened inside the auxiliary mounting seat 9. A connecting column 903 is movably sleeved on the inner side of the bearing support 902. A mounting recessed frame 904 is fixedly installed on the top of the connecting column 903. A plurality of connecting holes 905 are opened inside the top ends of both sides of the mounting recessed frame 904. The interiors of both ends of the mounting recessed frame 904 are threadedly connected with positioning bolts 906. The docking holes 901 are evenly distributed in a circular shape inside the auxiliary mounting seat 9, and the connecting holes 905 are evenly distributed in a linear shape inside the top ends of the mounting recessed frame 904. The specifications and dimensions of the docking holes 901 are compatible with the specifications and dimensions of the mounting holes 401, the specifications and dimensions of the connecting holes 905 are compatible with the specifications and dimensions of the connecting seat 505, and the specifications and dimensions of the positioning bolts 906 are compatible with the specifications and dimensions of the docking holes 901.

[0046] The auxiliary mounting seat 9 is installed on the top of the middle arc slider 4, and the bolts are passed through the docking hole 901 and the mounting hole 401, so that the auxiliary mounting seat 9 is stabilized in position and the bottom is in sliding contact with the support platform 1 and the top of the middle mounting plate 6 to facilitate stable position. It is convenient to install the concave frame 904 to be sleeved on the outside of the threaded mounting frame 5, and the threaded mounting frame 5 is inverted so that the bolts are inserted into the connecting seat 505 and the connecting hole 905, so that the position of the threaded mounting frame 5 is fixed, and then it is convenient to provide rotation and adjustment for the threaded mounting frame 5, and after rotating the clamping and pushing direction of the threaded mounting frame 5, tighten the positioning bolt 906 into the docking hole 901, so as to facilitate rotation and adjustment at the required angle, and to increase the rotation clamping direction of the threaded mounting frame 5, thereby further facilitating the clamping operation of the special-shaped parts of the door and window aluminum frame and ensuring the stability of the structure.
