Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting, and in particular, to a motor mounting structure for a laser cutting machine. Background Art

[0002] The application of laser cutting machines has developed rapidly in the domestic market in recent years, especially in the field of sheet metal cutting and processing. It has the advantages of high cutting accuracy, fast cutting speed, adaptability to various complex graphics, automatic typesetting, smooth incision, low processing cost, etc. It has replaced punching machines, flame cutting, plasma cutting and other equipment.

[0003] In order to improve the efficiency of laser cutting, many laser cutting machines are now set to a double-layer platform structure that can be exchanged in parallel, which can exchange and perform laser cutting on multiple groups of cutting profiles. The exchange table structure of the laser cutting machine can greatly improve the processing efficiency. There are also many designs for the drive structure of the exchange platform. For example, the Chinese patent utility model patent CN207547877U provides a laser cutting machine exchange table drive mechanism, including a driving device, an active mechanism driven by the driving device, and a driven mechanism driven by the active mechanism. The active mechanism and the driven mechanism are connected by a transmission mechanism. The driving device includes a servo motor and a reducer. The active mechanism includes a driving shaft, a driving sprocket arranged on the driving shaft, and a driving small sprocket. The driven mechanism includes a driven shaft, a driven sprocket arranged on the driven shaft, and a driven small sprocket. The servo motor drives the driving shaft through the reducer, and the driving small sprocket is connected to the driven small sprocket through the transmission mechanism. The driving sprocket and the driven sprocket are respectively exchanged by dragging the workbench through the driving chain and the driven chain. The utility model can realize bilateral synchronous dragging and exchanging worktables, has the characteristics of compact and simple structure, easy processing and assembly, large dragging force, fast dragging speed, etc., and is particularly suitable for use in high-power laser cutting machine exchange tables.

[0004] However, the above-mentioned horizontal exchange laser cutting machine still has the following disadvantages: the motor used to drive the displacement of the working platform is still set on the outer side of the machine tool. Especially under the premise that the machine tool width of the larger and higher-power laser cutting machine is larger, the motor set on the side further increases the width of the machine tool, resulting in difficulties in transporting the high-power machine tool and occupying a large area during installation. Finally, the working platform of the high-power cutting machine is also very heavy. The double-sided motor setting leads to poor synchronization on both sides when the working platform is displaced, and the risk of failure is high.

[0005] Therefore, in order to solve the above problems, it is necessary for us to design a reasonable and efficient motor mounting structure for laser cutting machines. Utility Model Content

[0031] Next is the setting of the motor part 1. The motor part 1 is set on the connecting plate 23 at the end of the machine tool part 2, so that the motor part 1 is located between the first wall panel 21 and the second wall panel 22, and does not occupy the entire width of the machine tool part 2.
