Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool technology, and in particular to a vertical multi-station CNC machine tool. Background Technology

[0002] Vertical CNC machine tools are commonly used high-precision machining equipment in the manufacturing industry. Their core function is to perform milling, drilling, tapping, and boring operations on metal and non-metal workpieces. Their vertical layout facilitates chip removal and operation, and when paired with a CNC system, they can precisely control the tool path, reducing human error. Suitable for machining small to medium-sized workpieces, they are widely used in mold making, electronic components, automotive parts, and other fields, stably achieving high-precision machining, improving production efficiency, and meeting the needs of batch or customized manufacturing.

[0003] Existing vertical CNC machine tools have significant shortcomings. First, the efficiency of process switching and parameter adjustment is low. When changing workpieces or processes, tooling fixtures need to be manually recalibrated and tool parameters set, which is time-consuming and prone to errors due to manual operation. This makes it difficult to quickly respond to the needs of small-batch, multi-variety production. Second, most of them are single-station designs and cannot process multiple parts at the same time. Even if some models support multiple processes, they are mostly serial processing modes, resulting in a high proportion of idle time and limited capacity. They are difficult to match the high-volume, fast-paced modern production scenarios and require additional investment in equipment or manpower to make up for the efficiency gap.

[0004] Therefore, this application provides a vertical multi-station CNC machine tool to meet the requirements. Utility Model Content

The top of the spindle sleeve is provided with an end cover, the top of the end cover is provided with a chuck, the bottom of the end cover is provided with a spindle, the bottom of the spindle is provided with pulleys, and a synchronous belt is provided between each of the pulleys. A main motor bracket is provided on one side of the base, a main motor plate is provided at the bottom of the main motor bracket, and a spindle motor is provided at the top of the main motor plate.

[0008] The beneficial effects of adopting the above-mentioned further solution are: the column at the top of the base provides rigid support for the overall structure, ensuring processing stability; the Z-axis guide slider and X-axis guide slider at the top of the column form a guiding structure, which, together with the X-axis linear guide, enables the precise translation of the small pallet, reduces movement gaps, improves positioning accuracy, ensures smooth tool feed, and improves the consistency of processing dimensions.

The Z-bearing stably supports the end of the lead screw, reducing transmission wobbling. The sliding block slides along the lead screw and drives the small support plate to move, thereby achieving feed accuracy control, reducing transmission error, and improving machining dimensional accuracy and motion stability.

[0011] Furthermore, a Z-axis motor is provided at the top of the column, a Z-axis lead screw is provided at the bottom of the Z-axis motor, Z-axis guide rails are provided on one side of the column, a Z-axis large support plate is slidably mounted on the Z-axis lead screw, and an X-axis large support plate is provided on the side of the column away from the Z-axis large support plate.

[0012] The beneficial effects of adopting the above-mentioned further solution are: the Z-axis motor at the top of the column drives the bottom Z-axis lead screw to rotate, converting power into linear motion; the guide rail between the Z axes on one side of the column provides guidance and constraint for the Z-large pallet, ensuring that it slides smoothly along the lead screw; the X-large pallet on the other side of the column can expand the processing station, realize multi-process synchronous operation, and improve processing efficiency and equipment utilization.

[0013] Furthermore, an X-bearing is provided on one side of the small tray, and the other end of the X-axis lead screw away from the Z-bearing is connected to the X-bearing.

[0014] The beneficial effects of adopting the above-mentioned further solution are: the X bearing on one side of the small support plate is connected to the other end of the X-axis lead screw, and the Z bearing is used to realize the positioning of both ends of the lead screw, reduce deflection, and improve transmission accuracy and stability.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] The base is equipped with a spindle sleeve at the top, providing stable support for the internal spindle and ensuring its coaxiality during high-speed rotation. The top end cover of the spindle sleeve is sealed to prevent dust, reduce the intrusion of impurities, and extend the spindle's life. The chuck on the top of the end cover clamps the workpiece, ensuring accurate positioning during machining and reducing the impact of vibration. The bottom pulley of the spindle is connected to the spindle motor via a synchronous belt, achieving efficient power transmission and ensuring stable speed. The main motor bracket on one side of the base is fixed to the main motor plate to reduce operating vibration and improve transmission accuracy. Ultimately, this achieves high-precision and high-efficiency machining of the workpiece. It should also be equipped with two workstations, allowing the machine tool to simultaneously machine the same side of a workpiece or different sides of the same workpiece.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1-4As shown, this utility model provides a technical solution: a vertical multi-station CNC machine tool, including a base 1, and a spindle sleeve 6 disposed on the top of the base 1. An end cover 8 is disposed on the top of the spindle sleeve 6, and a chuck 19 is disposed on the top of the end cover 8. A spindle 7 is disposed at the bottom of the end cover 8, and pulleys 12 are disposed at the bottom of the spindle 7. Synchronous belts 15 are disposed between the pulleys 12. A main motor bracket 11 is disposed on one side of the base 1, a main motor plate 10 is disposed at the bottom of the main motor bracket 11, and a spindle motor 16 is disposed on the top of the main motor plate 10. The spindle sleeve 6 on the top of the base 1 provides stable support for the internal spindle 7, ensuring its stability. The coaxiality during high-speed rotation is ensured by the top end cover 8 of the spindle sleeve 6, which seals and prevents dust, reduces the intrusion of impurities, and extends the life of the spindle 7. The top chuck 19 of the end cover 8 clamps the workpiece, ensuring accurate positioning during processing and reducing the impact of vibration. The bottom pulley 12 of the spindle 7 is connected to the spindle motor 16 through the synchronous belt 15, achieving efficient power transmission and ensuring stable speed. The main motor bracket 11 on one side of the base 1 and the main motor plate 10 fix the spindle motor 16, reducing running vibration and improving transmission accuracy. Ultimately, this achieves high-precision and high-efficiency processing of the workpiece. It should also have two workstations, allowing the machine tool to process the same side of a workpiece simultaneously or different sides of the same workpiece.

[0025] Furthermore, such as Figures 1-4 As shown: A column 2 is provided on the top of the base 1, and a Z-axis guide slider 22 is provided on the top of the column 2. An X-axis guide slider 23 is provided on the Z-axis guide slider 22, and an X-axis linear guide 21 is provided on each of the X-axis guide sliders 23. A small support plate 9 is provided on the X-axis linear guide 21. The column 2 on the top of the base 1 provides rigid support for the overall structure, ensuring processing stability. The Z-axis guide slider 22 and the X-axis guide slider 23 on the top of the column 2 form a guiding structure, which, together with the X-axis linear guide 21, enables the precise translation of the small support plate 9, reduces movement gaps, improves positioning accuracy, ensures smooth tool feed, and improves the consistency of processing dimensions.

[0026] The above solutions still have issues with processing accuracy, such as... Figures 1-4 As shown: In this scheme, an X-axis lead screw 24 is installed inside the Z-axis guide rail slider 22. An X-axis motor 17 is installed on one side of the X-axis lead screw 24, and a Z-bearing 13 is installed on one side of the X-axis motor 17. A sliding block 5 is slidably installed on the X-axis lead screw 24, and a small support plate 9 is slidably installed on the sliding block 5. The X-axis lead screw 24 inside the Z-axis guide rail slider 22 is linked with the X-axis motor 17 to convert the rotational motion into linear drive. The Z-bearing 13 stably supports the end of the lead screw, reducing transmission wobbling. The sliding block 5 slides along the lead screw and drives the small support plate 9 to move, thereby achieving feed accuracy control, reducing transmission errors, and improving machining dimensional accuracy and motion stability.

[0027] Working principle: such as Figures 1-4As shown, a spindle sleeve 6 is provided on the top of the base 1 to provide rigid support for the internal spindle 7, ensuring its coaxiality during high-speed rotation and reducing radial runout. The end cap 8 on the top of the spindle sleeve 6 provides a seal against dust, blocking the intrusion path of impurities and extending the service life of the spindle 7. The chuck 19 on the top of the end cap 8 forms a reliable position by clamping the workpiece, reducing vibration displacement during processing and ensuring dimensional accuracy. The bottom pulley 12 of the spindle 7 is connected to the spindle motor 16 via a synchronous belt 15, achieving zero-slip power transmission and ensuring speed stability. The main motor bracket 11 and the main motor plate 10 on one side of the base 1 are combined to fix the spindle motor 16, suppressing operating vibration and improving transmission accuracy. The column 2 on the top of the base 1 provides rigid support for the overall structure, enhancing its resistance to deformation and ensuring processing stability. The Z-axis guide slider 22 and X-axis guide slider 23 on the top of the column 2 form a guiding structure, which, together with the X-axis linear guide 21, guides the small support plate 9 to move precisely, reducing movement gaps and improving positioning accuracy. To ensure smooth tool feed and improve machining dimensional consistency, the X-axis lead screw 24 inside the Z-axis guide rail slider 22 is linked with the X-axis motor 17 to convert rotational motion into linear drive. The Z-bearing 13 stably supports the end of the lead screw, reducing transmission wobbling. The sliding block 5 slides along the lead screw and drives the small support plate 9 to move, realizing closed-loop control of feed accuracy and reducing transmission error. The Z-axis motor 18 at the top of the column 2 drives the bottom Z-axis lead screw 25 to rotate, converting power into linear motion. The Z-axis guide rail 20 on one side of the column 2 provides guidance and constraint for the large Z support plate 3, ensuring its smooth sliding along the lead screw. The large X support plate 4 on the other side of the column 2 expands the machining station, realizing simultaneous operation of multiple processes. The X-bearing 14 on one side of the small support plate 9 is connected to the other end of the X-axis lead screw 24, and works with the Z-bearing 13 to achieve rigid positioning at both ends of the lead screw, reducing deflection deformation and further improving transmission accuracy and operational stability. The dual-station design can process the same or different sides of the workpiece simultaneously, greatly improving machining efficiency.
