Description

Technical Field

[0001] This utility model relates to the field of door and window manufacturing technology, specifically to a welding device for door and window processing. Background Technology

[0002] Aluminum alloy windows are windows with frames and sashes made of aluminum alloy building profiles. They are divided into ordinary aluminum alloy doors and windows and thermally broken aluminum alloy doors and windows. Aluminum alloy windows are beautiful, airtight, and have high strength. They are widely used in the field of construction engineering. In home decoration, aluminum alloy doors and windows are commonly used to enclose balconies.

[0003] In the actual production process of small and micro manufacturers, considering cost control, semi-automatic welding or manual welding methods are usually used to manufacture aluminum alloy doors and windows. In specific operations, the aluminum alloy profiles are first aligned, the welding position is carefully adjusted, and then the finishing welding is carried out to finally process the aluminum alloy profiles into aluminum alloy doors and windows.

[0004] However, the welding process is easily affected by many external factors, such as changes in temperature and humidity in the workshop environment, fluctuations in the stability of welding equipment, and fatigue caused by long hours of work by operators. These factors may make it difficult to accurately align aluminum alloy profiles during welding. Once an alignment deviation occurs, it is very likely to produce defective products, which not only increases production costs but also has a negative impact on subsequent product sales. Utility Model Content

[0005] In view of this, the present invention provides a welding device for door and window processing. The device can quickly position the aluminum alloy profiles for manufacturing door and window frames by using a workbench with fixed columns and positioning plates. It can also quickly align the joints of two aluminum alloy profiles. Therefore, it can avoid alignment deviations caused by external factors or operator fatigue, thereby avoiding the production of defective products, further reducing production costs and increasing production speed.

[0006] To solve the above technical problems, this utility model provides a welding device for door and window processing, including a workbench with symmetrically arranged mounting grooves on the upper part of the workbench. The mounting grooves can be integrally formed with the workbench by casting a mold during manufacturing. Each mounting groove is provided with a fixing column, which is fixedly connected to the inner side wall of the mounting groove. Each fixing column is provided with a positioning plate above it, which is positioned above the fixing column by a lifting column. Both positioning plates are designed with an L-shaped structure.

[0007] The angle between the facing surfaces of the two fixed columns is set to 90°;

[0008] A positioning mechanism is provided on the upper part of the workbench and on one side of the axis of the two fixed columns. The positioning mechanism is used to perform secondary positioning of the corners of the door and window frame.

[0009] Support columns are provided on the opposing surfaces of the two fixed columns and on the upper part of the workbench. The support columns are bolted to the vertical surface of one side of the fixed columns.

[0010] Cylinders are symmetrically arranged on the upper part of the worktable. The cylinders are bolted to the upper part of the worktable, and the cylinder push rods pass through the worktable. Support plates are connected to the ends of the push rods of the two cylinders. The support plates are fixedly connected to the ends of the cylinder push rods. Lifting plates are provided at one end of the two support plates and are fixedly connected to one end of the support plates. The two lifting plates are connected to the facing surfaces of the two support plates. Multiple lifting columns are provided on the upper part of the two lifting plates and are fixedly connected to the upper part of the lifting plates. Multiple sliding grooves are opened on the two fixed columns corresponding to the positions of the multiple lifting columns. The multiple sliding grooves can be integrally formed with the fixed columns by casting through a mold during manufacturing. Each lifting column is slidably connected in the corresponding sliding groove. Each positioning plate is fixedly connected to the upper part of the corresponding multiple lifting columns.

[0011] The positioning mechanism includes an adjusting column set on one side of the upper part of the worktable. A slot is opened on one side of the adjusting column. The slot can be integrally formed with the adjusting column by casting a mold during manufacturing. The cross-section of the slot is a V-shaped structure and the included angle of the slot is set to 90°. An installation plate is set inside the slot. The installation plate is set on the inner side wall of the slot and is connected to the upper part of the adjusting column by bolts.

[0012] The adjusting column is installed on the upper part of the worktable via a limit bracket, which is bolted to the upper part of the worktable.

[0013] The limit bracket is connected to a tightening bolt via a threaded connection.

[0014] Each positioning plate has a rubber pad attached to the side of the worktable. The rubber pad is fixed to the side of the positioning plate by means of a solvent bonding method.

[0015] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0016] 1. By using a workbench with fixed columns and positioning plates, the aluminum alloy profiles for manufacturing door and window frames can be quickly positioned and the joints of two aluminum alloy profiles can be quickly aligned.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the appendices of the embodiments of this utility model. Figure 1-4 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0030] like Figure 1 , 2The image shows a welding device for door and window processing, including a workbench 101. The workbench 101 provides stable support for all components on it. During use, the workbench 101 and its components are vertically connected to a support platform containing a welding machine via bolts to the side near the adjusting column 301. The upper part of the workbench 101 has symmetrically arranged mounting grooves, which provide stable support for the fixing columns 102 and facilitate the creation of multiple sliding grooves. The mounting grooves can be integrally formed with the workbench 101 using a mold during manufacturing, resulting in a more stable connection structure and easier manufacturing. Fixing columns 102 are installed in both mounting grooves to ensure stable support for the components on them. The support enhances the stability of the components. The fixing column 102 is fixedly connected to the inner wall of the mounting groove, making the connection structure more stable. Each fixing column 102 is equipped with a positioning plate 103. The positioning plate 103 allows two symmetrical positioning plates 103 to align and position the two aluminum alloy profiles during the processing of the door and window frame. The positioning plate 103 is set above the fixing column 102 by the lifting column 204, so that it can be adjusted according to the specifications of the door and window frame, making it suitable for door and window frames of different sizes. Both positioning plates 103 are set with an L-shaped structure, which can further improve the positioning effect and ensure that each pair of aluminum alloy profiles to be welded can be stably positioned under them.

[0031] like Figure 1 , 2 As shown: The included angle between the facing surfaces of the two fixed posts 102 is set to 90°, allowing the two fixed posts 102 to position each pair of aluminum alloy profiles to be welded. This enables each pair of aluminum alloy profiles to be quickly aligned with the facing surfaces of the two fixed posts 102 without much operation, avoiding alignment deviations caused by external factors or operator fatigue, thus preventing the production of defective products. A positioning mechanism is provided on the upper part of the workbench 101 and on one side of the axis of the two fixed posts 102. The positioning mechanism is used for secondary positioning of the corners of the door and window frame, which can further improve the positioning effect and allow the operator to quickly align the profiles. Precise positioning of the door and window frames can improve welding speed and reduce operation difficulty. Support columns 104 are provided on the facing surfaces of the two fixed columns 102 and on the upper part of the workbench 101. The support columns 104 can be used to place door and window frames with grooves on the edges, thereby further improving the applicability of the overall structure and preventing deformation of door and window frames with grooves on the edges due to the squeezing force generated by the downward movement of the positioning plate 103. The support columns 104 are bolted to the vertical surface of one side of the fixed column 102, which not only facilitates quick assembly and disassembly according to the processing requirements of different door and window frames, but also facilitates position adjustment.

[0032] like Figure 2 , 3 As shown: Symmetrically arranged cylinders 201 are mounted on the upper part of the workbench 101. The cylinders 201, when their push rods move up and down, drive the movement of their components, allowing for rapid adjustment of the position of the positioning plate 103. This enables the positioning plate 103 to clamp and position door and window frames of various sizes. The cylinders 201 are bolted to the upper part of the workbench 101, facilitating easy disassembly and replacement for maintenance or replacement. The push rods of the cylinders 201 pass through the workbench 101, allowing the positioning plate 103 to be raised and lowered from below the workbench 101 in conjunction with the components. The ends of the push rods of the two cylinders 201... Each support plate 202 is connected to a support plate 202, which provides stable support for the lifting plate 203 and its components, allowing them to rise and fall accordingly. The support plate 202 is fixedly connected to the end of the push rod of the cylinder 201, making the connection structure more stable and improving the stability during lifting. A lifting plate 203 is provided at one end of each support plate 202, which supports multiple lifting columns 204, allowing the multiple lifting columns 204 to steadily drive the positioning plate 103 connected to them to rise and fall quickly and stably. The lifting plate 203 is fixedly connected to one end of the support plate 202, making the connection structure more stable.

[0033] like Figure 2 , 3As shown: Two lifting plates 203 are connected to the facing surfaces of two support plates 202, allowing each lifting plate 203 to be positioned below a fixed column 102, thus facilitating the stable driving of the positioning plate 103. Multiple lifting columns 204 are provided on the upper part of each of the two lifting plates 203. These multiple lifting columns 204 support the positioning plate 103 and allow for position adjustment as the lifting columns 204 move. The multiple lifting columns 204 are fixedly connected to the upper part of the lifting plates 203, making the connection structure more stable. Multiple sliding grooves are provided on the two fixed columns 102 corresponding to the positions of the multiple lifting columns 204. These grooves allow for the adjustment of the position of the lifting columns 204. 04. Limiting is performed to prevent the lifting column 204 from jamming during lifting. Multiple sliding grooves can be integrally formed with the fixed column 102 by casting through molds during manufacturing, making the connection structure more stable and facilitating production. Each lifting column 204 is slidably connected in its corresponding sliding groove, so that the sliding column will not jam when moving. Each positioning plate 103 is fixedly connected to the upper part of the corresponding multiple lifting columns 204, so that the positioning plate 103 can be raised and lowered with the movement of the lifting column 204. Furthermore, the positioning plate 103 can be stably supported to prevent tilting when positioning the door and window frame.

[0034] like Figure 3 , 4 As shown: The positioning mechanism includes an adjusting column 301 set on one side of the upper part of the workbench 101. The adjusting column 301 is set to be applicable to various specifications of door and window frames. That is, if the thickness of the door and window frame is different, the length of the distance between the two fixed columns 102 will also be different. Therefore, the adjusting column 301 can position the ends of each pair of aluminum alloy profiles to be welded, which can further improve the stability of the overall structure. A slot is opened on one side of the adjusting column 301. The slot can further improve the positioning effect of the aluminum alloy profile. The slot and the adjusting column 301 can be integrally formed by casting with a mold during the manufacturing process, so that the connection structure is more stable and easier to manufacture. The cross-section of the slot is a V-shaped structure and the included angle of the slot is set to 90°, which can further improve the positioning effect of the slot on each pair of aluminum alloy profiles and further improve the positioning stability.

[0035] like Figure 3 , 4As shown: A mounting plate 302 is installed inside the groove. The mounting plate 302 prevents friction between the aluminum alloy profile to be welded and the groove, thus avoiding a decrease in precision. This allows for quick replacement of the mounting plate 302 after wear, further preventing precision degradation. The mounting plate 302 is located on the inner wall of the groove, ensuring a closer fit and improving accuracy. It is bolted to the upper part of the adjusting column 301, facilitating easy disassembly and assembly for replacement or maintenance. The adjusting column 301 is mounted on the upper part of the worktable 101 via a limiting bracket 401, allowing for easy position adjustment according to the dimensions of the door and window frame, thus adapting to various door and window frame specifications. The limiting bracket 401 is bolted to the upper part of the worktable 101, thus... To facilitate position adjustment and fixation, the adjusting column 301 is easily adjustable. The limiting frame 401 is connected to a tightening bolt 402 via a threaded connection. The tightening bolt 402 facilitates adjustment of its position, thereby further fixing the position of the adjusting column 301 and improving its stability. Each positioning plate 103 has a rubber pad 501 connected to the side facing the workbench 101. The rubber pad 501 further prevents damage to the aluminum alloy profile during positioning, and also prevents damage to the door and window frame during processing and welding. The rubber pad 501 is fixed to the side of the positioning plate 103 by a sol-gel connection, making the connection structure more stable.

[0036] In use, the workbench 101 is vertically mounted on the support platform on which the welding machine is placed by bolts on the side closest to the adjusting column 301. Then, the position of the adjusting column 301 is adjusted according to the specifications of the aluminum alloy profiles to be welded. Then, the two sides of each pair of aluminum alloy profiles to be welded are pushed close to the side of the corresponding fixed column 102 facing the adjusting column 301, so that the ends of each pair of aluminum alloy profiles can be connected. Then, the welding machine can be turned on to weld the connection. By continuously flipping and changing the ends of the aluminum alloy profiles, the connection of the four aluminum alloy profiles can be welded.

[0037] Once the ends of the aluminum alloy profile are aligned, the cylinder 201 can drive the positioning plate 103 to move up and down via the lifting column 204. This allows one end of the positioning plate 103 to automatically clamp the aluminum alloy profile, thereby further improving the stability during welding. This avoids alignment deviations caused by external factors or operator fatigue, thus preventing the production of defective products, further reducing production costs, and increasing production speed.

[0038] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0039] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
