Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool technology, specifically to a high-precision CNC machine tool. Background Technology

[0002] CNC machine tools are machine tools that automatically perform processing according to pre-programmed procedures. They are widely used in the manufacturing industry for processing various precision parts. Existing CNC machine tools integrate advanced technologies such as microelectronics, computers, communication, and automatic control, achieving high-efficiency, high-precision, and automated production processing.

[0003] Traditional CNC machine tools typically require waiting for the completion of one workpiece before clamping and preparing the next. This results in the machine tool being idle during the waiting period, reducing production efficiency. To improve the efficiency of CNC machine tools, existing technologies have undergone a series of improvements and innovations. For example, by optimizing program design and process routes to reduce machining time and non-cutting time, and by using automatic tool changers and automatic loading / unloading robots to shorten workpiece changeover time, these improvements still cannot achieve the goal of pre-clamping and preparing the next workpiece while the machine tool is in operation. Utility Model Content

[0004] The purpose of this invention is to provide a high-precision CNC machine tool to address the aforementioned shortcomings in the technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A high-precision CNC machine tool includes a base, with two bases on the top of the base and a sliding mechanism between the two bases. A main worktable and a secondary worktable are mounted on the sliding mechanism. A CNC machine head is mounted above the main worktable. The sliding mechanism includes a linear motor, with a slide rail above the linear motor that passes through the main worktable and the secondary worktable. Two sliding components are mounted on the linear motor, with the top of each sliding component connected to the bottom of the main worktable and the secondary worktable.

[0007] One end of the main workbench is connected to a first baffle plate, and the other end is connected to a second baffle plate. One side wall of the second baffle plate is in contact with the end of the auxiliary workbench. Both the main workbench and the auxiliary workbench are provided with sliding seats at their bottoms.

[0008] Preferably, the sliding assembly includes a slider disposed on the linear motor lead screw, and a sliding plate is disposed on the top of the slider.

[0009] Preferably, the slide block has a triangular prism structure, and the bottom of the first baffle plate and the second baffle plate are provided with inverted V-shaped openings. The first baffle plate and the second baffle plate can slide on the top of the slide block. The top of the slide block is symmetrically provided with two sliding grooves, and the slide plate can extend upward and pass through the sliding grooves.

[0010] Preferably, the top of both the main worktable and the auxiliary worktable are equipped with clamps, and a CNC host is provided on the outside of the CNC machine head. The CNC host is fixed on the top of the base. A guide frame is provided at the bottom of one end of the CNC host, and a limit frame is provided at the bottom of the other end. The first baffle plate can pass through the guide frame, and the second baffle plate can pass through the limit frame. An infrared emitter is provided on one side wall of the first baffle plate, and an infrared receiver adapted to the infrared emitter is provided on the top of the base.

[0011] Preferably, guide plates are provided at both ends of the bottom of the slide, and the extended ends of the guide plates are in contact with the top of the base.

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] This utility model provides, for example Figures 1-4 The high-precision CNC machine tool shown includes a base 3, with two bases 6 on the top of the base 3. A sliding mechanism is provided between the two bases 6. A main worktable 13 and a secondary worktable 14 are provided on the sliding mechanism. A CNC machine head 2 is provided above the main worktable 13. The sliding mechanism includes a linear motor 21. A slide rail 15 is provided above the linear motor 21. The slide rail 15 passes through the main worktable 13 and the secondary worktable 14. Two sliding components are provided on the linear motor 21. The top of the sliding components is connected to the bottom of the main worktable 13 and the secondary worktable 14.

[0024] One end of the main worktable 13 is connected to a first baffle plate 10, and the other end is connected to a second baffle plate 11. One side wall of the second baffle plate 11 is in contact with the end of the auxiliary worktable 14. The bottom of both the main worktable 13 and the auxiliary worktable 14 is provided with a slide block 18. The sliding assembly includes a slider 20 mounted on the lead screw of the linear motor 21, and a slide plate 19 is mounted on the top of the slider 20.

[0025] In this embodiment, specifically, before the CNC machine tool is started, the first workpiece is installed on the main worktable 13, and the CNC machine head 2 of the CNC machine tool performs processing on the workpiece. The specific working principle of this part is existing technology and will not be described in detail here. During the processing of the first workpiece, the user or an intelligent robotic arm is installed on one side of the base 3 to install the workpiece. The second workpiece is installed on the auxiliary worktable 14. After the first workpiece is processed, the linear motor 21 is started, the slider 20 moves laterally, and drives the slide plate 19, the main worktable 13 and the auxiliary worktable 14 to move synchronously. The auxiliary worktable 14 reaches the original position of the main worktable 13, the main worktable 13 moves to the side, and unloads and reloads the workpiece. The unloading and reloading of the workpiece can be completed manually or by an intelligent robot.

[0026] like Figures 1-3 As shown, the slide 18 has a triangular prism structure. The bottom of the first baffle plate 10 and the second baffle plate 11 are provided with inverted V-shaped openings. The first baffle plate 10 and the second baffle plate 11 can slide on the top of the slide 18. Two sliding grooves 16 are symmetrically provided on the top of the slide 18. The slide plate 19 can extend upward and pass through the sliding grooves 16.

[0027] Specifically, the inner walls of the V-shaped openings at the bottom of the first baffle plate 10 and the second baffle plate 11 are in contact with the top of the slide block 18. During the movement of the main worktable 13 and the auxiliary worktable 14, the first baffle plate 10 and the second baffle plate 11 move synchronously.

[0028] like Figures 1-3 As shown, clamps 17 are provided on the top of both the main worktable 13 and the auxiliary worktable 14. A CNC host 1 is provided on the outside of the CNC machine head 2. The CNC host 1 is fixed on the top of the base 3. A guide frame 4 is provided at the bottom of one end of the CNC host 1, and a limit frame 12 is provided at the bottom of the other end. The first baffle plate 10 can pass through the guide frame 4, and the second baffle plate 11 can pass through the limit frame 12. An infrared transmitter 8 is provided on one side wall of the first baffle plate 10, and an infrared receiver 9 adapted to the infrared transmitter 8 is provided on the top of the base 6.

[0029] In this embodiment, the clamp 17 can be a four-jaw chuck, a three-jaw chuck, or a bolt fastening structure. The workpiece is clamped by the clamp 17, and the CNC machine head 2 performs processing on the workpiece. During this process, the first baffle plate 10 blocks the two sides of the main worktable 13, and the second baffle plate 11 blocks the two sides of the auxiliary worktable 14 to prevent debris from splashing to the sides of the main worktable 13 or the auxiliary worktable 14, and to facilitate the collection of debris.

[0030] Specifically, when the main worktable 13 and the auxiliary worktable 14 slide on the slide rail 15 and are used alternately, the infrared rays emitted by the infrared transmitter 8 are received and sensed by the infrared receiver 9. The CNC host 1 will receive a feedback signal, thereby controlling the linear motor 21 to stop working, so that the main worktable 13 and the auxiliary worktable 14 can accurately stop at the corresponding positions on the slide rail 15.

[0031] like Figure 1 As shown, guide plates 7 are provided at both ends of the bottom of the slide 18, and the extended ends of the guide plates 7 are in contact with the top of the base 3. The top of the base 3 is provided with material collection grooves 31 on both sides below the slide 18, and an opening is provided on one side of each of the two material collection grooves 31. Material collection boxes 51 are inserted into the interior of each of the two material collection grooves 31, and a baffle plate 5 is fixed to the end of the material collection box 51. The baffle plate 5 is placed at the opening.

[0032] Specifically, during the processing of the workpiece, the debris generated falls onto the guide plate 7 and then automatically slides down to the collection trough 31, eventually falling into the collection box 51. By pulling the baffle plate 5, the collection box 51 is moved and exposed outside the base 3. The debris can then be sucked away by a vacuum cleaner, making it easy to collect the debris.

[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
