Description

Technical field:

[0001] The utility model relates to the technical field of door and window corner assembly, in particular to a processing surface outer corner positioning structure for corner assembly and a corner assembly machine. Background technology:

[0002] Corner assembly is an essential process in the production and processing of doors and windows. Its purpose is to connect profiles, maintain the overall stability of the door and window, and ensure that the door and window can withstand the impact of strong winds and heavy rain. Existing technologies have developed corner assembly machines (also known as punch riveting corner assembly machines) and pin corner assembly machines, depending on the different corner assembly processes. Some of these corner assembly machines integrate glue injection functions, achieving a unified design for corner assembly and glue injection. The promotion and application of existing corner assembly machines have significantly improved the quality and efficiency of door and window corner assembly, driving the development of the entire door and window industry.

[0003] Profile positioning is an essential part of a corner assembly machine. Currently, a combination of inner and outer corner positioning mechanisms is commonly used to achieve this. The outer corner positioning mechanism is directly fixed to the workbench and acts directly on the bottom of the profile for positioning. The inner corner positioning mechanism uses active feeding to push the profile against the outer corner positioning mechanism for corner positioning. For its specific structure, please refer to a Chinese patent disclosure regarding a corner assembly machine for assembling aluminum alloy window frames (authorization announcement number: CN221538816U). While existing profile positioning structures effectively fulfill the requirements for profile positioning, they present a further technical problem in practical applications. The existing external corner positioning mechanism acts on the bottom side of the profile, but the location where the corner is actually to be bumped, punched, or injected is not located at the bottom side of the profile (the external corner positioning surface), but rather on an inner concave surface in the middle area of ​​the profile (the inner concave surface is defined as the processing surface, which is also the processing reference surface). Therefore, the external corner positioning surface is inconsistent with the processing surface (processing reference surface), and the position of the processing surface and the external corner positioning surface varies for profiles of different specifications. This results in a change in the processing reference surface when processing different profiles. Therefore, the operating parameters of the angle assembly machine need to be manually adjusted based on the profile design dimensions or by measuring the distance the processing reference surface has changed. Such adjustments not only affect the operating efficiency of the angle assembly machine, but also result in adjustment errors, which in turn affect the quality of the angle assembly.

[0004] It should be noted that the above content falls within the technical knowledge of the inventor and does not necessarily constitute prior art. Utility model content:

[0005] The purpose of the utility model is to solve the problems existing in the prior art and provide a processing surface external corner positioning structure for corner combination and a corner combination machine, which has the advantages of reasonable structural design, using the processing surface as the external corner positioning surface, unchanged processing reference surface position for different profiles, accurate external corner positioning, and helps to improve the processing efficiency and quality of the corner combination machine.

[0006] The utility model achieves the above-mentioned purpose by adopting the following technical solutions:

[0008] The thickness of the outer corner positioning plate and the side positioning plate is less than the height of the profile processing surface.

[0009] The end of the outer corner positioning plate is provided with a V-shaped opening for outer corner positioning, and the angle of the V-shaped opening is equal to the angle of the profile.

[0010] Anti-collision grooves are provided at the corners of the V-shaped opening.

[0011] The upper end of the front support is provided with a plurality of threaded holes A, the outer corner positioning plate is provided with a waist-shaped hole A, and bolts A are connected between the waist-shaped hole A and the threaded hole A.

Specific implementation method:

[0029] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in combination with the accompanying drawings by way of examples.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0031] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on the differences from other embodiments.

[0032] In addition, the terms "horizontal", "longitudinal", "vertical", etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the position of the indicated technical features.

[0033] In this utility model, unless otherwise specified or limited, the terms "provided with," "arranged," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integrated connections; mechanical connections; direct connections, or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of these terms in this utility model based on specific circumstances.

[0034] like Figure 1-8 As shown, the outer corner positioning structure of the processing surface for corner assembly includes a workbench 1, a front support 2 is provided at the front end of the workbench 1, an outer corner positioning plate 3 is provided on the front support 2, side supports 4 are provided on both sides of the workbench 1, side positioning plates 5 are provided on the side supports 4, and a vertical spacing is left between the outer corner positioning plate 3 and the side positioning plate 5 and the workbench 1, and the outer corner positioning plate 3 and the side positioning plate 5 act on the processing surface 7 of the profile 6 respectively, and the profile 6 is placed on the workbench 1 for positioning. The technical solution of this application overturns the design concept of the existing corner assembly machine that uses the side bottom of the profile 6 as the outer corner positioning surface, and is the first to use the processing surface 7 of the profile 6 as the outer corner positioning surface. This design ensures that the processing surface 7 is always positioned on the outer corner positioning plate 3 regardless of the profile, thereby ensuring that the position of the processing reference surface does not change, and then there is no need to adjust the operating parameters when the profile is replaced, which is not only accurate in positioning but also highly efficient.

[0035] The thickness of the outer corner positioning plates 3 and side positioning plates 5 is less than the height of the working surface 7 of the profile 6. This ensures that the outer corner positioning plates 3 and side positioning plates 5 can act on the working surface 7. Even if the working surfaces 7 of different profiles have different heights (usually these height differences are very small), the outer corner positioning plates 3 and side positioning plates 5 can still act on the working surface 7 without having to adjust their height. Of course, if the distance between the working surface 7 and the bottom of the profile 6 changes significantly, the vertical height adjustment of the outer corner positioning plates 3 and side positioning plates 5 is usually necessary.

[0036] The end of the outer corner positioning plate 3 is provided with a V-shaped opening 8 for outer corner positioning. The angle of the V-shaped opening 8 is equal to the angle of the profile. The V-shaped opening 8 is mainly used to match the two profiles after the angle is formed, and can locate the outer corner of the two profiles 6. The angle of the profile is usually 90°, so the angle of the V-shaped opening 8 is usually designed to be 90°. However, a few customized doors and windows require an angle other than 90°. In this case, the angle of the V-shaped opening 8 can be adjusted accordingly.

[0037] The corners of the V-shaped opening 8 are provided with anti-collision grooves 9. After the two profiles 6 are assembled, their outer corners are sharp corners. When positioning, they are likely to collide with the corners of the V-shaped opening 8, which may cause the sharp corners of the profile 6 to deform due to the collision, thereby affecting the appearance of the door and window and the subsequent assembly accuracy. By designing the anti-collision grooves 9, the sharp corners can be prevented from colliding with the V-shaped opening 8, thereby protecting the sharp corners of the profile 6.

[0038] The front support 2 has multiple threaded holes A10 at its upper end, and the outer corner positioning plate 3 has waist-shaped holes A11. Bolts A12 connect these waist-shaped holes A11 and threaded holes A12. The outer corner positioning plate 3 is installed using a threaded connection. Using waist-shaped holes A11 for threaded connection facilitates commissioning of new equipment and achieves optimal cornering results. Once adjusted, no further adjustments are typically required.

[0039] The workbench 1 is equipped with a mounting base 13 at the front end. This base 13 is provided with a threaded hole B14. A corresponding waist-shaped hole B15 is provided on the front support 2. Bolts B16 connect the waist-shaped hole B15 to the threaded hole B14. This connection using waist-shaped holes B15 allows for vertical adjustment of the outer corner positioning plate 3. For most profiles, adjustment is unnecessary because the thickness of the outer corner positioning plate 3 and the side positioning plate 5 is less than the height of the work surface 7. The height of the work surface 7 relative to the workbench 1 for most profiles 6 varies only slightly. Vertical adjustment may only be necessary for special or custom-made profiles 6 with unusual shapes.

[0040] The mounting seat 13 is fixedly arranged on the workbench 1 (such as Figure 7 As shown) or by sliding avoidance mechanism 17 arranged on the workbench (as Figure 4As shown). The mounting base 13 is fixedly arranged on the workbench 1 and can basically meet most usage situations. The reason why another installation situation is provided here is mainly to take into account the situation of some customized doors and windows. The injection hole on such special doors and windows may be very close to the outer corner positioning plate 3. In addition, the injection head is usually larger than the injection hole, so there is a possibility that the injection component will interfere with the outer corner positioning plate 3. In order to completely solve the above potential situation and improve the versatility and reliability of the technical solution of this application, a sliding avoidance mechanism 17 is designed. The sliding avoidance mechanism 17 can make the outer corner positioning plate 3 withdraw first during injection, so that no interference will occur.

[0041] The sliding avoidance mechanism 17 includes a slide rail 1701 disposed on the workbench 1, a slider 1702 disposed on the slide rail 1701, the mounting base 13 disposed on the slider 1702, a cylinder mounting base 1703 disposed on the workbench 1, an avoidance drive cylinder 1704 disposed on the cylinder mounting base 1703, and the avoidance drive cylinder 1704 connected to the mounting base 13. The specific structure of the sliding avoidance mechanism 17 is given, and a pneumatic sliding design is used to achieve the avoidance action.

[0042] The side support 4 is provided with a vertical slot 18, and the corresponding side positioning plate 5 is provided with a sliding protrusion 19, which is disposed within the slot 18. The side positioning plate 5 has a threaded hole C20 at the rear end, and a corresponding waist-shaped hole C21 is provided vertically on the side support 4. A bolt C22 is provided between the waist-shaped hole C21 and the threaded hole C20. A structure for adjusting the height of the side positioning plate 5 is provided herein to meet various height adjustment requirements.

[0043] like Figure 9 The figure shows a corner machine that includes the above-mentioned external corner positioning structure for the processing surface. The figure shows the specific structure of the processing surface external corner positioning structure of the present application applied to the pin corner machine 23, which cooperates with the internal corner positioning mechanism 24 in the pin corner machine 23 to complete the corner positioning of the profile.

[0044] The above specific implementation methods cannot be used as a limitation on the protection scope of the present utility model. For those skilled in the art, any replacement, improvement or transformation made to the implementation methods of the present utility model falls within the protection scope of the present utility model.

[0045] Anything not described in detail in the present invention is well known to those skilled in the art.
