Description

Technical fields:

[0001] This utility model relates to the field of corner assembly machine technology, specifically to a split corner assembly workbench and a mobile corner assembly machine head. Background technology:

[0002] Corner assembly machines are key equipment for completing the corner assembly process of doors and windows. They are classified into three types based on the number of corners assembled: single-head, double-head, and four-head. Single-head and four-head corner assembly machines are widely used. Currently, the working principle and structural layout of corner assembly machines are relatively mature. They include a worktable; the front area of ​​the worktable is used for positioning the profiles and is equipped with an outer corner positioning mechanism, an inner corner positioning mechanism, and side plates. The rear half of the worktable is used to install the riveting mechanism. To meet the positioning requirements of different profiles, the positions of the outer corner positioning mechanism and the side plates are usually adjustable. For a specific structural example, refer to a corner assembly machine disclosed in Chinese Patent Publication No.: CN211191721U.

[0003] In four-head corner assembly machines, the size of the machine and the conveyor line limit the dimensions that can be processed for smaller frame and sash sizes, making it impossible to process smaller frames and sashes. Existing technologies typically optimize the machine's dimensions to enable the processing of smaller frames and sashes. This involves first optimizing the dimensions of the frame and its worktable, and then adapting the various components mounted on the worktable. Since there are numerous components on the worktable—including internal and external corner positioning mechanisms, as well as riveting mechanisms—this undoubtedly increases the difficulty of dimension optimization. Furthermore, some components lose their original performance after optimization. For example, the previously adjustable external corner positioning mechanism, which occupied a large space, cannot be effectively adjusted after optimization, thus losing the ability to position certain profiles. Ultimately, this results in limited dimension optimization of the corner assembly machine and no significant improvement. Therefore, it is necessary to redesign and optimize the existing corner assembly machine to reduce the optimization difficulty while achieving significant dimension optimization results, thus meeting the processing requirements for smaller frames and sashes.

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

[0033] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0034] Many specific details are set forth in the following description in order to provide 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.

[0035] The various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.

[0036] Furthermore, the terms “front end,” “back end,” “horizontal,” “vertical,” and “vertical” are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the location of the indicated technical feature.

[0037] In this utility model, unless otherwise explicitly specified and limited, the terms "provided with," "set up," and "connected" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0038] like Figure 1-8 As shown, the split-type corner assembly workbench includes a machine head base 1. A support 2 and a back panel 4 are respectively mounted on the upper end of the machine head base 1. A front panel 3 is mounted on the support 2, and the front panel 3 is designed to be higher than the back panel 4. This design overturns the existing integrated design concept of corner assembly workbenches, innovatively adopting a split design, that is, separately designing the front panel 3 and the back panel 4. The front panel 3 is used to position the corner assembly profile 13, and the back panel 4 is used to install the punching and riveting components required for corner assembly. The biggest advantage of this structural design is that the front panel 3 and the back panel 4 can be optimized separately according to needs, reducing the optimization difficulty and making it easier to achieve a smaller size for the front panel 3. At the same time, it can also accommodate various functions required for corner assembly. Especially under the premise of optimizing and reducing the size of the front panel, it still leaves sufficient installation space and design space to accommodate the conveyor line, which helps in further optimization of the four-head corner assembly machine.

[0039] The support 2 includes a base plate 201 disposed on the upper end of the machine head base 1 or the upper end of the back stage plate 4. A vertical plate 202 is provided on the base plate 201, and a top plate 203 is provided on the upper end of the vertical plate 202. A front stage plate 3 is provided on the top plate 203. The specific structure of the support 2 is given, realizing the design that the front stage plate 3 is higher than the back stage plate 4.

[0040] The top plate 203 protrudes forward from the upper end of the vertical plate 202. This design provides sufficient installation space below the top plate 203 for installing the inner corner positioning mechanism.

[0041] The base plate 201 has a recessed front end design 204, and the corresponding upright plate 202 is designed along the edge of the recessed base plate 204. This design further expands the installation space below the top plate 203, achieving a compact structural design while still leaving a large installation space.

[0042] The front panel 3 and the top panel 203 are provided with clearance openings 5 ​​at their front ends. The design of clearance openings 5 ​​can extend the movement space of the inner corner positioning, so that even when the size of the front panel 3 is reduced, the inner corner positioning movement space is still large. This helps to achieve smaller-sized corner assembly of the frame and sash, while also meeting the needs of larger-sized corner assembly.

[0043] The machine head base 1 includes a machine head base plate 101, machine head side plates 102 are respectively provided on both sides of the machine head base plate 101, and a machine head top plate 103 is provided at the upper end of the machine head side plate 102. A bracket 2 and a back support plate 4 are provided on the machine head top plate 103.

[0044] The front ends of the machine head base plate 101 and the machine head top plate 103 are symmetrically inclined inward at 45°, and a corresponding inclined front plate 104 is provided between the machine head base plate 101 and the machine head top plate 103. This design is mainly to match the 90° angle, which helps to save space.

[0045] The front panel 3 and top panel 203 extend in a direction perpendicular to the inclined front panel 104 to form a receiving space 6. This design enables the concealment of the conveyor line and facilitates the further processing of smaller frame sashes in a four-head corner assembly machine.

[0046] A pad 14 is provided on the upper end of the front panel 3. The pad 14 here mainly serves to protect the profile and can be made of bakelite board.

[0047] The mobile corner assembly machine head includes a split corner assembly worktable as described above. The back panel 4 is equipped with a corner assembly adjustment mechanism 7 to adjust the position of the assembled corners. The corner assembly adjustment mechanism 7 is equipped with a servo corner assembly mechanism 8. The corner assembly adjustment mechanism 7 is used to adjust the corner position. The front panel 3 is used to place the corner assembly profile 13. In practical applications, an outer corner positioning block 9, two side plates 10, and an inner corner positioning mechanism 11 need to be installed on the front panel 3 to position the corner assembly profile 13. A vertical clamping mechanism 12 is also typically installed on the adjusting slide plate 703. By designing the corner adjustment mechanism 7 on the back panel 4, the corner position can be adjusted conveniently and accurately. When double-point cornering is required, there is no need to replace the double-point cornering tool. The corner position can be adjusted again by the corner adjustment mechanism 7. In addition, after the corner adjustment mechanism 7 raises the height of the servo cornering mechanism 8, it matches the height of the front panel 3, without the need for additional height compensation. Furthermore, the outer corner positioning block 9 and the side plate 10 can be directly changed to a fixed design. The fixed design helps to further reduce the size of the front panel 3.

[0048] The angle adjustment mechanism 7 includes an adjustment guide rail 701 mounted on a back plate 4, an adjustment slider 702 mounted on the adjustment guide rail 701, an adjustment slide plate 703 mounted on the adjustment slider 702, and an adjustment reducer 704 vertically mounted on the adjustment slide plate 703. The adjustment reducer 704 has an adjustment motor 705 at its input end and an adjustment gear 706 at its output end. The back plate 4 has an adjustment rack 707 that meshes with the adjustment gear 706. The specific structure of the angle adjustment mechanism 7 is given; typically, electric drive and gear and rack transmission achieve precise and rapid adjustment of the position.

The corner-grouping crank arm 812 is rotatably mounted on the adjusting slide plate 703. The front end of the corner-grouping crank arm 812 is connected to the knife box base 813. The lower end of the knife box base 813 is provided with a feed slider 814. The feed slider 814 is mounted on a feed guide rail 815. The feed guide rail 815 is mounted on the adjusting slide plate 703. The front end of the knife box base 813 is provided with a knife box 816.
