Description

Technical Field

[0001] The invention belongs to the field of machine tools and relates to a fully fitted machine tool protective device. Background Art

[0002] Machine tools are indispensable equipment in the manufacturing industry, and they play a key role in various machining processes. However, during the high-speed, high-precision machining process of machine tools, the axial movement and radial movement of the worktable place higher demands on the machine tool protective devices. Existing machine tool protective devices usually cannot meet the needs of axial movement, radial movement, and axial buffer damping at the same time. During the axial movement and radial movement, the fit between the worktable and the protective device is often not tight enough, resulting in the inability to achieve complete sealing of the machining area, thus affecting the machining quality and the service life of the machine tool. In addition, the existing protective devices lack an effective buffer damping mechanism during the axial movement, which can easily cause damage to machine tool components, increase maintenance costs and downtime.

[0003] To solve these problems, some existing technologies try to provide better sealing and buffering performance by improving the design of the guard. For example, some guards use adjustable sealing structures to adapt to the axial movement and radial motion of the workbench. However, these structures are often too complicated, making the installation and maintenance of the guard difficult and costly. Other technologies use springs or other elastic elements to provide axial buffering damping, but these solutions may not be stable and reliable enough under high-speed and high-load working conditions. Summary of the invention

[0004] In view of this, the object of the present invention is to provide a fully fitted machine tool protection device, which can achieve full sealing of axial movement and radial movement, and at the same time provide buffering damping for axial movement to protect machine tool components, improve processing accuracy and the service life of the machine tool.

[0005] In order to achieve the above object, the present invention provides the following technical solutions:

[0045] Table 6: Table 6 is a part of the machine tool and needs to perform axial movement and radial movement. The design of this device ensures that the table 6 is completely sealed with the protective device when performing these movements.

[0046] Damping buffer mechanism 7: The damping buffer mechanism 7 is used to apply buffering damping to the axial movement of the workbench 6 and ensure that the workbench is always in a state of contact with the protective mechanism when the workbench moves axially during processing. It includes a fixed connecting rod 16, a telescopic rod 18, a movable connecting rod 19, a first spring 13, a second spring 14 and an elastic retaining ring 15.

[0047] Dust ring 8: The dust ring 8 is installed at the moving end 10 of the protective device to prevent dust and other foreign matter from entering the interior of the machine tool.

[0048] Telescopic accordion cover 9: The telescopic accordion cover 9 is used to connect the moving end 10 and the fixed end 11 of the protective device to form a sealed protection for the working area of ​​the machine tool.

[0049] Moving end 10: The moving end 10 is a part of the protective device and is connected to the moving end of the workbench 6.

[0050] Fixed end 11: The fixed end 11 is another part of the protective device and is connected to the fixed structure of the machine tool.

[0051] Locking nut 12: The locking nut 12 is used to fix the components of the connecting rod 16 to ensure its stability and reliability.

[0052] The first spring 13 and the second spring 14: The first spring 13 and the second spring 14 are part of the damping buffer mechanism 7, which are used to provide buffering damping for axial movement, and through the elastic force of the two-stage springs, ensure that the workbench and the sealing mechanism are always in a fitting state during axial movement.

[0053] Circlip 15: The circlip 15 is used to fix and position the components of the mobile connecting rod 19.

[0054] Fixed connecting rod 16 : The fixed connecting rod 16 is used to connect the damping buffer mechanism 7 and the fixed end 11 .

[0055] Linear guide sleeve 17: The linear guide sleeve 17 is used to guide the linear motion of the telescopic rod 18 and the movable connecting rod 19 to ensure the smoothness of the axial sliding.

[0056] Telescopic rod 18: The telescopic rod 18 is a part of the damping and buffering mechanism 7, and is used to achieve buffering and damping of axial movement.

[0057] Movable connecting rod 19 : The movable connecting rod 19 is used to connect the damping buffer mechanism 7 and the workbench 6 .

[0058] The workbench 6 needs to move axially and radially in the direction of the arrow in the figure. During the entire movement process, the protective device must remain completely sealed. When the workbench 6 enters the protective cover, its larger end face fits tightly with the damping buffer mechanism 7 of the protective device. The protective device is evenly equipped with four damping buffer mechanisms 7 to ensure that the workbench 6 is evenly stressed during the movement. After fitting in place, Figure 2 As shown, the outer ring of the workbench 6 is tightly matched with the dust ring 8 to ensure the independence of the entire processing area. The dust ring 8 is installed at the moving end 10 of the protective device, and the moving end 10 is connected to the fixed end 11 through the telescopic bellows cover 9 to form a complete protective structure.

[0059] The structure of the damping buffer mechanism 7 is as follows: Figure 3 As shown, the fixed connecting rod 16 is connected to the fixed end 11 by connecting parts such as screws and locking nuts 12. The fixed end 11 and the movable end are buffered by two-stage springs, namely the first spring 13 and the second spring 14, which reasonably reduces the space of the entire structure and ensures the stability of the elastic force output by the damping and buffering mechanism 7. The telescopic rod 18 cooperates with the fixed connecting rod 16 and the movable connecting rod 19 through a linear guide sleeve 17 to ensure that the entire axial sliding process is smooth. When the workbench 6 moves radially, the movable end applies a lateral force to the damping and buffering mechanism 7, and the force is transmitted to the fixed end 11, so that the entire protective device moves laterally on the protective door 4. The entire lateral movement is achieved by the V-shaped guide rail 2 installed on the fixed end 11, and moves along the roller 3 on the protective door 4.

[0060] In order to facilitate access to the maintenance area during maintenance, the entire protective door 4 can be opened by the door opening cylinder 1, and its opening state is as follows: Figure 4 After the maintenance is completed, the protective door 4 is closed by the door opening cylinder 1, and the protective door 4 is locked on the machine tool protective door mounting frame by the door locking cylinder 5.
