They are mainly used for cutting and machining the inner and outer cylindrical surfaces, inner and outer conical surfaces with arbitrary cone angles, complex rotating inner and outer curved surfaces, and cylindrical and conical threads of shaft or disc parts. They can also perform grooving, drilling, reaming, boring, and other machining operations.

[0003] Chinese Patent CN217965799U discloses a multi-station CNC machine tool for PCB cutting tools. It includes a machine tool base, a servo motor fixedly mounted on the right side surface of the base, and a threaded drive rod connected to the output end of the servo motor via the inner wall of the base. This utility model provides a multi-station CNC machine tool for PCB cutting tools that can drive a processing tray frame along a T-shaped sliding groove to perform sequential processing under a multi-station CNC milling and drilling module via the threaded drive rod at the output end of the servo motor.

[0004] The aforementioned technologies have some shortcomings. In actual use, manual adjustment is required when fixing material plates, resulting in low operating efficiency and inconvenience. In addition, the technology can only fix material plates of different thicknesses and cannot effectively fix materials of different widths, making it less versatile. Therefore, it is necessary to provide a multi-station CNC machine tool to solve the above technical problems. Utility Model Content

[0005] The purpose of this utility model is to provide a multi-station CNC machine tool to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A multi-station CNC machine tool, comprising:

[0008] The base has symmetrically distributed feet fixedly installed on both sides of its bottom. An electric track is fixedly installed on the top of the base. A slider is slidably installed on the electric track. A processing tray is fixedly installed on the top of the slider. A processing positioning groove is opened on the top of the processing tray.

[0009] Several CNC milling and drilling modules are provided on the rear side of the top of the base. Each CNC milling and drilling module is equipped with a milling drill bit. First cylinders are fixedly installed on both sides of the processing tray, and the driving end of the first cylinder penetrates through the processing tray and extends into the interior of the processing positioning groove. Clamping plates are fixedly installed on the driving ends of the two first cylinders.

[0010] The top of the clamping plate is provided with a movable plate, and a second cylinder is fixedly installed on one side of the top of the movable plate. The driving end of the second cylinder passes through the movable plate and extends to the bottom of the movable plate. A pressure plate is fixedly installed on the driving end of the second cylinder.

[0011] Preferably, a protective cover is fixedly installed on the top of the base, and symmetrically distributed protective door panels are hinged to the front of the protective cover. A latch is provided at the connection between two of the protective door panels, and a transparent glass is fixedly embedded in both of the protective door panels.

[0012] Preferably, an installation cavity is provided at the top of the clamping plate, a rotating shaft is rotatably mounted on the top of the clamping plate, and the bottom end of the rotating shaft passes through the clamping plate and extends into the interior of the installation cavity. A servo motor is fixedly installed inside the installation cavity, and the drive end of the servo motor is fixedly connected to the bottom end of the rotating shaft. The top end of the rotating shaft is fixedly connected to the bottom of the movable plate.

[0013] Preferably, the top of the clamping plate is provided with an annular slide rail, and the bottom of the movable plate is fixedly installed with a plurality of limiting blocks, which are slidably installed on the annular slide rail.

[0014] Preferably, anti-slip pads are adhered to the opposite surfaces of the two clamping plates and the bottom of the two pressure plates.

[0015] Preferably, the limiting block is in the shape of an inverted T-shaped mechanism, and the limiting block is adapted to the annular slide.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model utilizes a base, a CNC milling and drilling module, a milling drill bit, an electric track, a slider, a processing tray, a processing positioning groove, a clamping plate, a first cylinder, a second cylinder, a movable plate, and a pressure plate in combination. This equipment offers significant advantages in practical applications. On one hand, the fixing method for the material plate is fully mechanized, avoiding the tedious manual operation of the mechanical structure, effectively improving the efficiency of material plate assembly and disassembly, and ensuring operational safety and reliability. On the other hand, by controlling the lateral movement of the two clamping plates on the side of the material plate, it can effectively fix material plates of different widths, significantly improving the equipment's versatility.

[0018] 2. This utility model utilizes a protective cover, protective doors, and transparent glass for visualization. When the equipment is in operation, the two protective doors on the front of the protective cover can be closed. At this time, the processing area located at the top of the base forms a closed space with the help of the protective cover and doors, effectively isolating it from the outside environment. This prevents flying debris generated during equipment operation from directly injuring nearby personnel, thereby improving the safety and reliability of equipment operation.

[0019] 3. This utility model, through the coordinated use of a servo motor, mounting cavity, and rotating shaft, allows for the upward movement and repositioning of a single-sided pressure plate during material plate processing if the processing area is covered or obstructed by a pressure plate. Subsequently, the servo motor is activated, its drive end rotating the rotating shaft. This rotation causes a movable plate to rotate, which in turn moves the pressure plate away from the material plate via a second cylinder. In this way, the milling drill bit at the corresponding position can effectively process the area originally obstructed by the pressure plate, ensuring comprehensive workpiece processing without requiring manual adjustment of the material plate position, thus possessing high practicality.

[0029] Please see Figures 1-4 One embodiment provided by this utility model:

[0030] A multi-station CNC machine tool, comprising:

[0031] The base 1 has symmetrically distributed feet 11 fixedly installed on both sides of the bottom of the base 1. The top of the base 1 is fixedly installed with an electric rail 4. A slider 5 is slidably installed on the electric rail 4. A processing tray 6 is fixedly installed on the top of the slider 5. A processing positioning groove 7 is opened on the top of the processing tray 6.

[0032] Several CNC milling and drilling modules 2 are provided on the rear side of the top of the base 1. Milling and drilling heads 3 are provided on the CNC milling and drilling modules 2. First cylinders 13 are fixedly installed on both sides of the processing tray 6. The driving end of the first cylinder 13 passes through the processing tray 6 and extends into the interior of the processing positioning groove 7. Clamping plates 12 are fixedly installed on the driving ends of the two first cylinders 13.

[0033] A movable plate 20 is provided on the top of the clamping plate 12. A second cylinder 19 is fixedly installed on one side of the top of the movable plate 20. The driving end of the second cylinder 19 passes through the movable plate 20 and extends to the bottom of the movable plate 20. A pressure plate 21 is fixedly installed on the driving end of the second cylinder 19.

[0034] A protective cover 8 is fixedly installed on the top of the base 1. The front of the protective cover 8 is hinged with symmetrically distributed protective door panels 9. A latch is provided at the connection between the two protective door panels 9. A transparent glass 10 is fixedly embedded on both protective door panels 9. The transparent glass 10 allows the operator to observe the operation of the equipment and the processing of materials in the processing area in real time, detect abnormalities in time and deal with them, and does not affect the protective effect.

[0035] In one embodiment, a mounting cavity 15 is provided above the interior of the clamping plate 12. A rotating shaft 17 is rotatably mounted on the top of the clamping plate 12, and the bottom end of the rotating shaft 17 passes through the clamping plate 12 and extends into the interior of the mounting cavity 15. A servo motor 14 is fixedly mounted inside the mounting cavity 15, and the drive end of the servo motor 14 is fixedly connected to the bottom end of the rotating shaft 17. The top end of the rotating shaft 17 is fixedly connected to the bottom of the movable plate 20.

[0036] In one preferred embodiment, the top of the clamping plate 12 is provided with an annular slide rail 18, and a plurality of limiting blocks 16 are fixedly installed at the bottom of the movable plate 20, and the limiting blocks 16 are slidably installed on the annular slide rail 18, thereby improving the stability of the movable plate 20.

[0037] In one embodiment, anti-slip pads are bonded to the opposite surfaces of the two clamping plates 12 and the bottom of the two pressure plates 21, which can increase the friction between the material plates and make the material plates more securely fixed, avoid displacement during processing, and ensure processing accuracy and quality.

[0038] In one preferred embodiment, the limiting block 16 is shaped as an inverted T-shaped mechanism, and the limiting block 16 is adapted to the annular slide 18, which can ensure that the limiting block 16 slides stably within the annular slide 18, prevent it from falling out, and enhance the structural stability and motion reliability.

[0039] The working principle of this utility model is as follows: The entire device is controlled by a main control button. Since the device matched with the control button is a common device and belongs to existing common knowledge technology, its electrical connection relationship and specific circuit structure will not be described in detail here. The parts of this device not mentioned are the same as existing technology or can be implemented using existing technology. When the device is in use, according to different processing requirements, a suitable milling drill bit 3 is installed at the output end of the CNC milling and drilling module 2. Then, the material plate to be processed is placed in the processing positioning groove 7 on the top of the processing tray 6. At this time, the two first cylinders 13 are activated, and their driving ends extend into the processing positioning groove 7, pushing the two clamping plates 12 in the processing positioning groove 7 to move relative to each other, thereby achieving clamping of both sides of the material plate. Immediately afterwards, the two second cylinders 19 are controlled, and their driving ends drive the pressure plate 21 to move vertically until the pressure plate 21 touches the top edge of the material plate, completing the fixed and limited operation of the material plate in the processing positioning groove 7. Subsequently, the slider 5 is controlled to slide on the electric track 4, thereby changing the lateral position of the processing tray 6 and moving the material plate fixed on the processing tray 6 to different positions of the milling drill bit 3 for sequential processing. This equipment has significant advantages in practical applications. On the one hand, the fixing method of the material plate is fully mechanized, avoiding the tedious manual operation of the mechanical structure, effectively improving the efficiency of material plate assembly and disassembly, and ensuring the safety and reliability of operation. On the other hand, by controlling the lateral movement of the two clamping plates 12 on the side of the material plate, material plates of different widths can be effectively fixed, significantly improving the versatility of the equipment.

[0040] When in use, with the equipment running, the two protective doors 9 on the front of the protective cover 8 can be closed. At this time, the processing area located on top of the base 1 will form a closed space with the help of the protective cover 8 and the protective doors 9, effectively isolating it from the outside world. This can prevent flying debris generated during equipment operation from directly injuring nearby personnel, thereby improving the safety and reliability of equipment operation.

[0041] In use, if the processing area is covered or obstructed by the pressure plate 21 during the material plate processing, the pressure plate 21 on one side can be moved upwards to reset. Then, the servo motor 14 is activated, its drive end rotates the rotating shaft 17, and the rotation of the shaft 17 causes the movable plate 20 to rotate accordingly. The rotation of the movable plate 20, through the second cylinder 19, moves the pressure plate 21 away from the material plate. In this way, the milling drill 3 at the corresponding position can effectively process the area originally obstructed by the pressure plate 21, ensuring comprehensive workpiece processing. It eliminates the need for manual adjustment of the material plate position, making it highly practical.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
