Description

Technical field:

[0001] The utility model relates to the technical field of door and window profile processing equipment, in particular to a damage-free positioning and pressing device for profile milling, and is especially suitable for processing high-end door and window profiles. Background technology:

[0002] Milling is an essential process in the production of doors, windows, curtain walls, sun rooms and other products. For example, the processing of glue injection holes, corner code installation holes, lock holes and other processing all require milling. The existing technology generally uses CNC milling machines to mill profiles. The CNC milling machine mainly includes a frame, a workbench is provided on the frame, a mechanism for positioning and pressing the profile is provided on the workbench, a three-translational mechanism is provided behind the workbench, a milling motor is provided on the three-translational mechanism, and a milling cutter is provided on the milling motor. The milling cutter performs milling on the profile.

[0003] Existing CNC milling machines have profiles (such as Figure 7 The existence of the above technical problems directly affects the assembly accuracy of subsequent products, and thus affects the product quality. In order to solve the above technical problems, many attempts have been made in the prior art, such as the profile end damage-free positioning structure and clamp previously applied by our company (authorization announcement number: CN218946944U). This technical solution effectively solves the above technical problems and has been put into practice. With the fierce market competition, products are required to be continuously optimized and upgraded in order to further improve performance and / or reduce costs and / or simplify structure and / or be more compact. Figure 8 As shown, our company's previous profile end damage-free positioning structure adopts two translation mechanisms and end positioning blocks. The vertical drive of the two translation mechanisms occupies a large space and is costly. In addition, the end positioning block is not only large in size, but also requires a 45° opening to be processed on the end positioning block. Not only is the processing cost high, but it also requires a corresponding 45° angle. When processing other inclination angles, the end positioning block needs to be replaced accordingly. The overall structure occupies a large space and has a relatively high cost. Therefore, it is necessary to optimize it in order to make the structural design more compact, reduce costs and increase versatility.

Specific implementation method:

[0025] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in the form of examples in conjunction with the accompanying drawings.

[0026] 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 protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0027] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other, and each embodiment focuses on the differences from other embodiments.

[0028] In addition, the terms "lateral", "longitudinal", "vertical", "upper end", "lower end", etc. are used for descriptive purposes only and cannot be understood as indicating or suggesting relative importance or implicitly indicating the position of the indicated technical features.

[0029] In the present invention, unless otherwise clearly specified and limited, the terms "provided with", "set", "connected" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] like Figure 1-6 As shown, a damage-free positioning and clamping device for milling holes of profiles comprises a worktable 1, two supporting plates 2 are provided at intervals at the rear end of the worktable 1, a limiting opening 3 is provided on the worktable 1 between the two supporting plates 2, a translation mechanism 4 is provided at the lower end of the worktable 1, a slide plate 5 is provided at the end of the translation mechanism 4, the translation mechanism 4 drives the slide plate 5 to move horizontally, a positioning cylinder 6 is vertically provided on the slide plate 5, a positioning column 8 is provided at the upper end of the piston rod 7 of the positioning cylinder 6, a limiting block 9 is provided on the slide plate 5, the positioning column 8 and the limiting block 9 are located in the limiting opening 3, and the limiting opening 3 limits the lateral sliding of the limiting block 9, rear positioning blocks 10 are respectively provided at the rear ends of the worktable 1 on both sides of the limiting opening 3, a downward pressing mechanism 11 is provided at the upper end of the supporting plate 2, and two side pressing mechanisms 12 are provided at intervals on the worktable 1. Compared with the existing profile damage-free positioning structure 19 (including two translation mechanisms 20, an end positioning block 21 and a 45° opening 22), the present application directly designs a positioning column 8 on the positioning cylinder 6. Not only does it not require an additional vertical guide mechanism, but the positioning column 8 can also meet the end positioning requirements of the profile 16 with different inclination angles, which has the advantages of reduced cost, compact structure and strong versatility.

[0031] The translation mechanism 4 includes a slider 401 disposed transversely at the lower end of the workbench 1, a guide rail 402 is disposed on the slider 401, the slide plate 5 is disposed on the guide rail 402, a driving cylinder 403 (which can be installed by installing a cylinder seat for installing the driving cylinder 403) is disposed at the lower end of the workbench 1, and the driving cylinder 403 is connected to the slide plate 5. The specific structure of the translation mechanism 4 is given, and the cylinder is used to cooperate with the slider guide rail for precise guidance to achieve transverse drive.

[0032] The outlet end of the positioning cylinder 6 is provided with a guide copper sleeve 13, and the piston rod 7 is arranged in the guide copper sleeve 13. By designing the guide copper sleeve 13, the vertical movement accuracy of the positioning column 8 can be significantly improved, thereby ensuring accurate and reliable positioning.

[0033] The limiting block 9 is designed to be in a rectangular parallelepiped shape, and the limiting opening 3 is designed to be in a U-shape. The rectangular parallelepiped and U-shaped designs have the advantages of being easy to process and having accurate and reliable limiting.

[0034] The rear positioning block 10 is provided with a rear positioning surface 14, which is flush with the front end surface 15 of the back plate 2. This ensures accurate and reliable rear positioning of the end of the profile 16. It should be explained here that since the profile 16 needs to be milled, a sufficient distance needs to be left between the two back plates 2, so the end of the profile 16 needs to be additionally rear-positioned to ensure reliable positioning and pressing during the milling process.

[0035] The pressing mechanism 11 comprises a cylinder support 1101 disposed at the upper end of the support plate 2 , a pressing cylinder 1102 is vertically disposed on the cylinder support 1101 , and a pressing block 1103 is disposed on the pressing cylinder 1102 , so as to realize the vertical pressing of the profile 16 .

[0036] The side pressure mechanism 12 comprises a side pressure cylinder 1201 longitudinally arranged on the workbench 1, and a side pressure block 1202 is arranged on the side pressure cylinder 1201 to achieve horizontal compression of the profile.

[0037] Instructions for use of the damage-free positioning and clamping device for profile milling holes in this application:

[0038] In actual use, the profile 16 can be milled alternately in left and right cycles, which significantly improves the milling efficiency.

[0039] First, drive the cylinder 403 to push the slide plate 5 to the right (that is, the limit block 9 is in contact with the right side of the limit opening 3), and then place the profile 16 horizontally on the right side of the workbench 1, and then lean the profile 16 against the back plate 2 and push it to the left at the same time so that the end of the profile 16 is positioned on the positioning column 8 (the inclined surface 17 and the sharp corner 18 at the end of the profile 16 are protected), and finally the downward pressure cylinder 1102 and the side pressure cylinder 1201 on the right side are respectively actuated to position and press the profile 16, and the profile 16 can be milled after being positioned and pressed, and at the same time, the cylinder 403 is driven to reset so that the slide plate 5 moves to the left (that is, the limit block 9 is in contact with the left side of the limit opening 3), and then the other profile 16 is positioned and installed on the left side of the workbench 1 (the positioning and pressing process is basically the same as the above), and after the installation is completed, wait for the milling hole. In this way, the time for milling the hole can be fully utilized, and the profile 16 on the other side can be positioned, pressed and installed, so as to realize cyclic alternation of profile milling hole processing, thereby significantly improving the processing efficiency.

[0040] The above-mentioned specific implementation manner 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 change made to the implementation manner of the present utility model falls within the protection scope of the present utility model.

[0041] The matters not described in detail in the present invention are all known technologies to those skilled in the art.
