[0032] The following disclosure provides many different implementation methods or examples for different solutions to implement this utility model.

[0033] On the one hand, such as Figures 1 to 5 As shown, this embodiment of the utility model provides a pneumatic circuit board fixing device for a machine tool. For example... Figure 1 and Figure 2As shown, the pneumatic circuit board fixing device of the machine tool includes a fixed base 1, a folding connection mechanism 2, and a pneumatic circuit board 3; the fixed base 1 is the connecting carrier to the machine tool and is fixed on the machine tool, and the pneumatic circuit board 3 is used to install pneumatic circuit components, which facilitates centralized installation and pipeline layout; the folding connection mechanism 2 includes a first movable arm 21 and a second movable arm 22 that are rotatably connected to each other, connecting the fixed base 1 and the pneumatic circuit board 3 and transmitting the movement of the pneumatic circuit board 3.

[0034] The fixed base 1 is rotatably connected to the first end of the first movable arm 21, the second end of the first movable arm 21 is rotatably connected to the first end of the second movable arm 22, and the second end of the second movable arm 22 is rotatably connected to the air circuit plate 3 via hinge structures 4. The folding connection mechanism 2 has at least a folded state and an unfolded state. In the folded state, the first movable arm 21 and the second movable arm 22 are stacked, resulting in a compact overall structure that occupies minimal space and improves the adaptability of the air circuit system. In the unfolded state, the first movable arm 21 and the second movable arm 22 are used to adjust the angle and position of the air circuit plate 3 relative to the fixed base 1. The adjustment method is flexible and requires no additional adjustment tools. The air circuit plate 3 can be adjusted to a comfortable angle for the operator, eliminating the need for the operator to bend over or reach into narrow spaces. This simplifies the installation and maintenance process of the air circuit plate and improves the efficiency of inspection and replacement.

[0035] like Figure 3 As shown, the hinge structure 4 includes a bushing 41 and a rotating shaft 42. The rotating shaft 42 passes through the bushing 41 and can rotate relative to the bushing 41 around the axis. The rotational motion is transmitted to the adjacent components through the hinge structure 4.

[0036] like Figures 3 to 5 As shown, the bushing 41 includes a first bushing 411 disposed on the fixed base 1, a second bushing 412 disposed on the second end of the first movable arm 21, and a third bushing 413 disposed on the air passage plate 3; the rotating shaft 42 includes a first rotating shaft 421 disposed on the first end of the first movable arm 21, a second rotating shaft 422 disposed on the first end of the second movable arm 22, and a third rotating shaft 423 disposed on the second end of the second movable arm 22; the first rotating shaft 421 is sleeved in the first bushing 411, the second rotating shaft 422 is sleeved in the second bushing 412, and the third rotating shaft 423 is sleeved in the third bushing 413.

[0037] When the operator pushes the air circuit plate 3, the third bushing 413 moves synchronously with the air circuit plate, causing the third rotating shaft 423 to rotate around the axis of the third bushing 413, driving the second movable arm 22 to swing around that point as a fulcrum; when the second movable arm 22 swings, the second rotating shaft 422 at the first end of the second movable arm 22 rotates around the second bushing 412 at the second end of the first movable arm 21, causing the included angle between the first movable arm 21 and the second movable arm 22 to change, and the motion is transmitted to the first movable arm; when the first movable arm 21 moves, the first rotating shaft 421 at the first end of the first movable arm 21 rotates around the first bushing 411 on the fixed seat 1, ultimately realizing the adjustment of the position and angle of the air circuit plate 3 relative to the fixed seat 1.

[0038] like Figures 3 to 5 As shown, each of the first movable arm 21 and the second movable arm 22 comprises two units. The two first movable arms 21 are arranged in parallel, and the two second movable arms 22 are arranged in parallel, forming a double-sided parallel linkage structure. The first bushing 411, the second bushing 412, the third bushing 413, the first rotating shaft 421, the second rotating shaft 422, and the third rotating shaft 423 comprise two units. The two first bushings 411 are respectively located on the upper and lower parts of the fixed base 1, and the two third bushings 413 are respectively located on the upper and lower parts of the pneumatic circuit plate 3. This avoids excessive force on one side, which could lead to tilting and swaying, and ensures that the pneumatic circuit plate 3 maintains a stable posture during adjustment, protecting the safety of the operator and the pneumatic components. At the same time, it is compatible with fixed bases 1 and pneumatic circuit plates 3 of different lengths, improving the versatility for different types of machine tools, and can bear heavier pneumatic components.

[0039] like Figure 1 and Figure 2 As shown, the first movable arm 21 has a groove-shaped structure. In the folded state, the second movable arm 22 is housed within the groove-shaped structure. When the folding connection mechanism switches from the unfolded state to the folded state, the second movable arm 22 gradually moves inward and eventually embeds into the groove-shaped structure of the first movable arm 21. At this time, the first movable arm 21 and the second movable arm 22 are stacked, reducing the overall volume of the folding connection mechanism after folding. This is especially suitable for confined spaces such as machine tool control cabinets, and avoids interference with electrical components, pipelines, etc.

[0040] like Figure 1 As shown, a fixed plate 31 is provided on the air circuit plate 3. The second movable arm 22 is rotatably connected to the fixed plate 31 through a hinge structure 4, and a third bushing 413 is provided on the fixed plate 31. The fixed plate 31 acts as a rigid intermediary, converting the rotational motion of the hinge structure 4 into the overall posture adjustment of the air circuit plate 3 without changing the structural stability of the air circuit plate 3 itself. The fixed plate 31 increases the contact area with the air circuit plate 3, distributing the concentrated load of the hinge structure 4 to a larger area of ​​the air circuit plate 3, reducing local stress that could cause deformation and cracking of the air circuit plate.

[0041] like Figure 1 As shown, the hinge structure 4 between the fixed base 1 and the first movable arm 21, the hinge structure 4 between the first movable arm 21 and the second movable arm 22, and the hinge structure 4 between the second movable arm 22 and the air passage plate 3 have parallel axes to each other, ensuring that the movement of the folding connection mechanism is completely synchronized, ensuring that the rotational freedom of all the hinge structures 4 is limited to the same plane, avoiding motion interference caused by multi-directional rotation, and making the air passage plate 3 stable and reliable during the adjustment process.

[0042] like Figure 4 As shown, the fixing plate 31 has multiple first oblong holes 311 extending along its length. Fastening bolts pass through these first oblong holes 311. By adjusting the fastening bolts, the fixing plate 31 can be moved along the length of the first oblong holes 311, allowing for fine-tuning of its installation position on the pneumatic circuit board 3, effectively shortening assembly time. If the hinge structure 4 wears and shifts after long-term use, coaxiality can be restored by fine-tuning the fixing plate 31, resolving the jamming problem without replacing parts. Furthermore, the same fixing plate 31 can be adapted to pneumatic circuit boards 3 of different thicknesses or hole layouts through positional adjustments, enhancing the versatility of the machine tool's pneumatic circuit board fixing device.

[0043] On the other hand, this utility model also provides a machine tool, including a machine tool body and a control cabinet disposed on the machine tool body, and further including a pneumatic circuit board fixing device for the machine tool as described above, wherein the fixing seat 1 of the pneumatic circuit board fixing device is fixedly disposed in the control cabinet. Since the machine tool has the aforementioned pneumatic circuit board fixing device, it also has the corresponding effect of the pneumatic circuit board fixing device, which will not be described in detail here.

[0044] like Figure 4 As shown, the fixed base 1 has multiple second oblong holes 11 extending along its length. Fastening bolts pass through these second oblong holes 11. By adjusting the fastening bolts, the fixed base 1 can be moved along the length of the second oblong holes 11, allowing for fine-tuning of its installation position on the machine tool. This prevents deformation of the fixed base 1 caused by forced installation and ensures the connection strength between the fixed base 1 and the machine tool. The same fixed base 1 can be adapted to different machine tool models through fine-tuning, reducing the need for customized parts due to machine tool differences and lowering production costs.

[0045] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
