[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / as well" as used herein includes any and all combinations of one or more of the associated listed items.
[0022] The following describes the embodiments in conjunction with the appendix. Figure 1-3 This utility model will be described in further detail.
[0023] A beam structure includes a first beam 1, a second beam 2, and a column 3.
[0024] The first crossbeam 1 includes a first guide rail 11, which is horizontally positioned.
[0025] The second crossbeam 2 includes a second guide rail 21, which is horizontally arranged. There are two second guide rails 21 located on both sides of the second crossbeam 2. Connectors 22 are provided on the edges of both sides of the second crossbeam 2. The connectors 22 are used to connect to the high-speed balancing system to balance the weight of the crossbeam component and improve the dynamic performance when the linear motor drives the crossbeam to move vertically.
[0026] Specifically, in this embodiment, the first crossbeam 1 and the second crossbeam 2 are hollowed out to reduce the weight of the crossbeams; the first crossbeam 1 and the second crossbeam 2 are provided with splicing slots 4, which are used to install and weld steel plates, and the performance of the crossbeams can be adjusted according to the stress of the parts.
[0027] The column 3 is provided with a first mounting surface 31, which is used to mount a linear motor to drive the crossbeam structure to move vertically. Specifically, in this embodiment, there are two columns 3.
[0028] A connection relationship of a beam structure:
[0029] The first crossbeam 1 and the second crossbeam 2 are fixedly connected by columns 3. The two columns 3 are fixed on both sides of the first crossbeam 1 and the second crossbeam 2. The first crossbeam 1 is located above the second crossbeam 2. The first guide rail 11 is located on the side of the first crossbeam 1, and the second guide rail 21 is located on the upper surface of the second crossbeam 2. The connection between the first crossbeam 1 and the column 3 is provided with reinforcing ribs 32 to enhance the crossbeam's resistance to bending when subjected to radial cutting force and reduce deformation under stress. The connection between the second crossbeam 2 and the column 3 is also provided with reinforcing ribs 32. The first mounting surfaces 31 on the two columns 3 face outward to facilitate the installation of linear motors. In this utility model, the components of the crossbeam are manufactured and connected by welding.
[0030] The working principle of a beam structure:
[0031] Linear motors are installed on the first mounting surface 31 of the columns 3 on both sides of the crossbeam structure. The crossbeam components are directly driven by a transmission-free method, which improves the dynamic response speed under high-speed drive, reduces wear, and improves positioning accuracy. With the dual-side motor drive, the crossbeam components have better stability and dynamic performance during high-speed movement. Steel plates can be flexibly added through the splicing ports 4 on the first crossbeam 1 and the second crossbeam 2 to change the center of gravity and weight of the crossbeam to adapt to different working environments.
[0032] The advantages of this utility model are: by installing linear motors on the first mounting surfaces 31 on both sides of the crossbeam, a dual-drive structure is formed on both sides of the crossbeam, which improves the dynamic response speed of the crossbeam components under high-speed movement, reduces wear, and improves positioning accuracy.
[0033] The above embodiments only illustrate one implementation of the present utility model, and should not be construed as limiting the scope of the utility model patent. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present utility model. These are all equivalent modifications and improvements made to the above embodiments based on the essential technology of the present utility model, and all of these fall within the protection scope of the present utility model.
