[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0028] Please refer to Figure 1-7 ;

[0029] The movable anti-collision tool holder of the pneumatic brake Swiss machine of the present invention is aimed at a multi-station processing device that can move relatively, and can improve the safety of the multi-station processing device, including a first processing tool holder 1, a second processing tool holder 2 and a fixed frame 3. The first processing tool holder 1 and the second processing tool holder 2 are arranged on the same side relative to the fixed frame 3. In other embodiments, the first processing tool holder 1 and the second processing tool holder 2 can be movable. In this embodiment, in the horizontal direction, the position of the second processing tool holder relative to the fixed frame 3 remains unchanged; two slide rails 4 are fixedly provided on the fixed frame 3, and the slide rails 4 are preferably dovetail slide rails 4, and the length direction of the two dovetail slide rails 4 is horizontal. The first processing tool holder 1 includes a moving device part 5 and a tool installation part 6. The moving device The placement portion 5 includes two slide grooves 7, which are preferably dovetail slide grooves 7, and the dovetail slide rails 4 are slidably connected to the dovetail slide grooves 7; the tool installation portion 6 is slidably connected to the moving device portion 5 in the vertical direction, and the tool installation portion 6 is used to install the tool. The moving structure of the second processing tool holder 2 in the vertical direction can be consistent with the vertical moving structure of the first processing tool holder 1; that is, the first processing tool holder 1 and the second processing tool holder 2 can both be moved in the vertical direction. In this embodiment, in the horizontal direction, the position of the second processing tool holder 2 relative to the fixed frame 3 is fixed, and the first processing tool holder 1 slides relative to the second processing tool holder 2, so as to flexibly adjust the relative positions of the two workstations according to different processing requirements, and adapt to the processing of workpieces of different sizes and shapes.

[0030] In this embodiment, a first driving motor 8 is fixedly provided on the fixed frame 3, and the first driving motor 8 can be installed on the fixed frame 3 on the side of the first processing tool holder 1 close to the second processing tool holder 2. Compared with installing the first driving motor 8 on the fixed frame 3 on the side away from the second processing tool holder 2, it can reduce the usage space and improve the flexibility of the Swiss machine. A screw pair is rotatably provided on the fixed frame 3, and the moving end of the screw pair is fixedly connected to the moving device part 5. The first driving motor 8 is rotatably connected to the screw of the screw pair through a reducer. The first driving motor 8 can drive the screw pair to rotate, thereby driving the first processing tool holder 1 to slide relative to the fixed frame 3. A first collective anti-collision part is provided on the end of the dovetail slide 4 away from the second processing tool holder 2. The first collective anti-collision part includes a blocking plate 10 and an elastic button 11. The blocking plate 10 is vertically arranged and is installed on the surface of the dovetail slide 4. The lower surface of the blocking plate 10 is fixedly connected to the surface of the dovetail slide 4. The blocking plate 10 can prevent the slide groove 7 of the out-of-control first processing tool holder 1 from detaching from the slide rail 4 Furthermore, in the present embodiment, the elastic button 11 is movably connected to the side of the blocking plate 10 facing the second processing tool holder 2, and the elastic button 11 can buffer the second processing tool holder 2 that is out of control from colliding with the blocking plate 10 due to inertia; the second processing tool holder 2 is provided with a second collective anti-collision part 9 on the side facing the first processing tool holder 1. In some other embodiments, the second collective anti-collision part 9 includes an anti-collision sponge to buffer the force of the impact. In the present embodiment, the second collective anti-collision part 9 includes a spring 12 and a soft cylinder 13, and a plurality of limiting grooves are provided on the fixed frame 3, which are connected to the soft cylinder 13, and one end of the spring 12 is located in the limiting groove, and the other end of the spring 12 is located in the cylinder of the soft cylinder 13.

[0031] It is worth noting that in order to be able to cut off the power supply of the first drive motor 8 and issue an alarm in time after the first drive motor 8 is damaged, two installation slots 14 are also provided on the fixed frame 3, and the controller and the alarm are distributed and installed in the two installation slots 14. The controller is electrically connected to the alarm, and the elastic button 11 is electrically connected to the controller. When the elastic button 11 is squeezed, on the one hand, it can buffer the impact of the first processing tool holder 1, and on the other hand, it can transmit a signal to the controller in time. The controller is electrically connected to the external power supply of the first drive motor 8. The controller can control the external power supply to be turned off in time after receiving the signal from the elastic button 11, and at the same time, the controller can control the alarm to send a warning signal; similarly, a strain gauge sensor is adhered to the surface of the spring 12, and the strain gauge sensor is electrically connected to the controller. When the spring 12 is deformed, the controller can control the external power supply to be turned off in time.

[0032] Specifically, under normal working conditions, the first processing tool holder 1 can be driven by the first drive motor 8 and driven by the screw pair in the horizontal direction according to the operator's instructions, and can be moved by the dovetail slide 7 and the dovetail slide rail 4 under stable sliding. When the motor is damaged, the out-of-control first processing tool holder 1 may suddenly move faster or lose power and move under inertia, which may cause the first processing tool holder 1 to separate from the fixed frame 3 or cause the first processing tool holder 1 to collide with the second processing tool holder 2. In this embodiment, when the first processing tool holder 1 moves out of control and away from the second processing tool holder 2, it will collide with the elastic button 11. The impact of the elastic button 11 can, on the one hand, cushion the impact of the first processing tool holder 1, and on the other hand, It can transmit signals to the controller in time, and at the same time, the blocking plate 10 can prevent the first processing tool holder 1 from losing control and detaching from the fixed frame 3; when the first processing tool holder 1 loses control and moves toward the second processing tool holder 2, it will hit the soft cylinder 13, and at the same time cause the spring 12 to deform, thereby buffering the force of the first processing tool holder 1 moving toward the second processing tool holder 2, and at the same time, a strain gauge sensor is adhered to the end of the spring 12 close to the first processing tool holder 1. When the spring 12 is deformed, the strain gauge sensor can transmit a signal to the controller. When the controller receives a signal from the elastic button 11 or the strain gauge sensor, the controller can timely control the external power supply to be turned off by the signal from the elastic button 11, and the controller can control the alarm to send a warning signal.

[0033] In this embodiment, the tool mounting portion 6 of the first processing tool holder 1 is installed with a drive motor 15, and the output end of the drive motor 15 is connected to a gear box 16. The gear box 16 has several output ends. In this embodiment, the rotation of the drive motor 15 and the heat generated by the gear box 16 can easily cause the tool to lose precision. A cooling component is provided between the output end of the drive motor 15 and the gear box 16. Specifically, the cooling component includes a cooling plate 17, which is located between the output end of the drive motor 15 and the gear box 16. A closed S-shaped groove 18 is provided inside the cooling plate 17. It is worth noting that a avoidance hole is also provided on the cooling plate 17 for the output shaft of the drive motor 15 to pass through. The output shaft of the drive motor 15 is fixedly connected to one side of the cooling plate 17, and the other side of the cooling plate 17 is fixedly connected to the side plate of the gear box 16. Two cooling pipes 19 are inserted at both ends of the cooling plate 17. The bottom ends of the cooling pipes 19 are communicated with the two openings of the S-shaped groove 18, and the other end of the cooling pipes 19 is connected to an external circulating cooling device.
