AI Technical Summary
但在实际应用中发现了深层次的技术问题,现有双头锯为了能够满足加工更小尺寸的型材,通常将锯片设置在摆角座的内侧(如图4所示),对应的旋转中心也是位于内侧,这种结构设计虽然有利于更小尺寸的锯切加工,但同时摆角座也会承受较大的偏心作用,尤其是整个锯切主体机构都设置在摆角座上这进一步放大偏心带来的不利影响,这很容易导致悬臂与载台连接处、前安装板与悬臂连接处以及后安装板与载台连接处发生开裂问题或者悬臂、前安装板以及后安装板发生变形问题,尤其是长时间使用后问题更加凸显
通过在摆角座的内侧设计延长底板A、延长底板B、延长前板、延长侧板实现将前安装板与悬臂、悬臂与载台、载台与后安装板连接处进行加强处理,使得整体结构强度加强,显著提升抗偏载能力,降低局部变形可能性,延长使用寿命。

Abstract
Description
Technical Field
[0001] This utility model relates to the field of double-head saw technology, specifically to a swing angle seat. Background Technology
[0002] The swivel mount is an essential component of a double-headed saw, primarily used to mount the main sawing mechanism and change the sawing angle by rotation. Currently, swivel mounts on the market have largely similar structures, mainly consisting of a platform, a cantilever at the front end of the platform, a front mounting plate at the front end of the cantilever, and a rear mounting plate at the rear end of the cantilever. Components of the main sawing mechanism, such as the feed guide rail, sawing motor, and feed driver, are mounted on the platform. The front and rear mounting plates are used for rotatable mounting on the sawing head. The saw blade is mounted on the sawing motor and located on one side of the platform. For a detailed structure, please refer to the attached diagram. Figure 3 .
[0003] The widespread application of existing swivel brackets has promoted the development and progress of double-head saws, especially in enabling adjustments to different sawing angles and broadening their application range. However, deeper technical problems have been discovered in practical applications. To process smaller profiles, existing double-head saws typically place the saw blade inside the swivel bracket (e.g., ...). Figure 4 As shown in the diagram, the corresponding rotation center is also located on the inner side. While this structural design is beneficial for smaller sawing operations, the swing arm also experiences significant eccentricity. This is especially true since the entire sawing mechanism is mounted on the swing arm, further amplifying the adverse effects of eccentricity. This can easily lead to cracking at the connections between the cantilever and the platform, the front mounting plate and the cantilever, and the rear mounting plate and the platform, or deformation of the cantilever, front mounting plate, and rear mounting plate, especially after prolonged use. Ultimately, this affects the processing accuracy of the equipment and may even require downtime for maintenance. Therefore, it is necessary to optimize and improve the existing swing arm to enhance its resistance to eccentric loads.
[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
[0005] The purpose of this utility model is to solve the problems existing in the prior art and provide a swing angle seat with the advantages of reasonable structural design, strong resistance to eccentric load, and high structural strength.
[0006] This utility model achieves the above objectives by adopting the following technical solutions: An angled bracket includes a platform with a cantilever at the front end and a rear mounting plate at the rear end. A front mounting plate is located at the front end of the cantilever. An extended base plate A is located at the bottom inner side of the platform, with its rear end connected to the rear mounting plate. An extended front plate is vertically located at the front end of the extended base plate A, and its inner side is aligned with the rear mounting plate. An extended side plate is located on the inner side between the extended front plate and the rear mounting plate. An extended base plate B is located at the bottom inner side of the cantilever, with its front end connected to the front mounting plate and its rear end connected to the extended base plate A. An obstruction opening for the saw blade to pass through is located on the extended front plate.
[0007] Weight reduction holes are provided on the extended base plate A, the extended side plate and the extended base plate B respectively.
[0008] The connection between the extended side plate and the extended base plate A is designed with a chamfer.
[0009] The present invention, by adopting the above-described structure, can bring the following beneficial effects: By designing extended base plate A, extended base plate B, extended front plate, and extended side plate on the inner side of the swing bracket, the connection between the front mounting plate and the cantilever, the cantilever and the platform, and the platform and the rear mounting plate are reinforced, thereby strengthening the overall structural strength, significantly improving the resistance to eccentric loads, reducing the possibility of local deformation, and extending the service life.

Detailed implementation method: To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.
[0010] 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.
[0011] 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.
[0012] Furthermore, the terms “front end,” “back end,” “inner side,” etc., 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.
[0013] 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.
[0014] like Figure 1-2 As shown, the swing bracket includes a platform 1, and the main sawing mechanism, such as a sawing motor 12, a saw blade 13, and a guide rail 14, is mounted on the platform. The platform 1 has a cantilever 2 at the front end and a rear mounting plate 3 at the rear end. The cantilever 2 has a front mounting plate 4 at the front end. The platform 1 has an extension base plate A5 at the bottom inner side. The rear end of the extension base plate A5 is connected to the rear mounting plate 3. The extension front plate 6 is vertically positioned at the front end of the extension base plate A5. The extension front plate 6 is aligned with the inner side of the rear mounting plate 3. This ensures that the added extension plate will not affect normal sawing processing, especially the minimum size sawing. An extension side plate 7 is provided on the inner side between the extension front plate 6 and the rear mounting plate 3. The cantilever 2 has an extension base plate B8 at the bottom inner side. The extension base plate B8 is connected to the front mounting plate 4 at the front end and to the extension base plate A5 at the rear end. The extension front plate 6 has an clearance opening 9 for the saw blade to pass through. Compared with existing swing brackets, this application strengthens the connection between the front mounting plate 4 and the cantilever 2, the cantilever 2 and the platform 1, and the platform 1 and the rear mounting plate 3 by designing an extended base plate A5, an extended base plate B8, an extended front plate 6, and an extended side plate 7 on the inner side of the swing bracket. This strengthens the overall structural strength, significantly improves the resistance to eccentric loads, reduces the possibility of local deformation, and extends the service life.
[0015] The extended base plate A5, extended side plate 7, and extended base plate B8 are each provided with weight-reducing holes 10. The shape of the weight-reducing holes 10 can be circular or oriented. The design of the weight-reducing holes 10 helps to reduce the weight of the swing bracket.
[0016] The connection between the extended side plate 7 and the extended base plate A5 is designed with a chamfer 11. The chamfer design helps to remove burrs, facilitates assembly, and improves safety and aesthetics.
[0017] The above specific embodiments should not be construed as limiting the scope of protection of this utility model. For those skilled in the art, any alternative improvements or modifications made to the embodiments of this utility model shall fall within the scope of protection of this utility model.
[0018] Any aspects of this utility model not described in detail are known to those skilled in the art.
