Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool technology, and in particular to a CNC machine tool with an automatic tool setting and rapid calibration tool. Background Technology

[0002] A CNC machine tool is a computer-controlled machine tool that combines mechanical technology, automation technology, computer technology, and information technology. It uses a digital control system to precisely operate the machine tool to complete processes such as machining, cutting, milling, and turning. An automatic tool setting and rapid calibration tool is a device used on CNC machine tools to automatically detect and calibrate parameters such as the length and radius of cutting tools. This tool improves machining accuracy, reduces manual intervention, and shortens production cycles.

[0003] In the existing technology, some CNC machine tools with automatic tool setting function can automatically identify and adjust the position of the tool to ensure the precise matching between the tool and the workpiece during the machining process. The machine tool is equipped with an automatic tool setting system, which usually adjusts the tool coordinate system automatically by measuring the tool length and diameter and triggering the measuring probe, reducing manual intervention and improving machining accuracy and efficiency. During operation, the CNC system controls the tool setting process to ensure that the tool is always in the correct working state during each machining process, avoiding machining errors caused by tool wear and position deviation.

[0004] However, in practical use, some tool calibration methods have significant limitations, mainly in that the calibration process is complex, time-consuming, and not precise enough. Usually, operators need to manually adjust the tool and complete the calibration process through trial cutting and measurement. This not only increases production downtime but also requires a high level of experience from the operators, which can easily lead to inaccurate calibration. In response to the above problems, a CNC machine tool with an automatic tool setting and rapid calibration tool is proposed. Utility Model Content

Fixed limit posts are fixedly connected to both sides of the bottom of the CNC machine tool operating table. A calibration mechanism is slidably connected to the outside of the fixed limit posts. A fixed connecting plate is fixedly connected to the outside of the CNC machine tool operating table. A switching mechanism is rotatably connected to the inside of the fixed connecting plate.

[0008] The calibration mechanism includes a U-shaped sliding plate, the interior of which is slidably connected to the exterior of two fixed limiting posts. The interior of the U-shaped sliding plate is fixedly connected to two fixed connecting rods, and the exterior of the two fixed connecting rods is slidably connected to two sliding clamping blocks. A connecting spring is fixedly connected to the side of the two sliding clamping blocks that is close to each other (i.e., the side furthest from the two sliding clamping blocks). Limiting components are fixedly connected to the exterior of the CNC machine tool operating table.

[0009] As a further description of the above technical solution:

A fixed block is externally fixedly connected to the fixed force-applying column, and a sliding limiting rod is internally slidably connected to the fixed block. The sliding limiting rod is externally slidably connected to the outer side of the U-shaped sliding plate.

[0018] The transmission component includes a rotating perforated plate, the interior of which is rotatably connected to the exterior of the first fixed connecting column, and a rotating sector plate is rotatably connected to the exterior of the first fixed connecting column.

This makes the tool switching process more efficient, shortens the replacement time, and improves work efficiency, making it suitable for production environments that require frequent tool changes.

Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0033] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of a CNC machine tool with an automatic tool setting and rapid calibration tool. The machine tool includes a CNC machine tool operating table 1, which has a rectangular structure and undergoes precision machining and grinding to ensure its flatness and stability, enabling it to withstand various loads generated during machine operation. Fixed limiting posts 11 are fixedly connected to both sides of the bottom of the CNC machine tool operating table 1, providing guidance and limiting for the subsequent calibration mechanism. A calibration mechanism is slidably connected to the outside of the fixed limiting posts 11. The calibration mechanism includes a U-shaped sliding plate 2, with grooves on both sides inside that fit the fixed limiting posts 11. Through the cooperation of the grooves and the fixed limiting posts 11, the U-shaped sliding plate 2 can slide left and right outside the fixed limiting posts 11. The internal sliding connection is external to the two fixed limiting posts 11. The internal fixed connection of the U-shaped sliding plate 2 is two fixed connecting rods 3, with their ends fixed to the inner walls of the two sides of the U-shaped sliding plate 2 respectively. The external sliding connection of the two fixed connecting rods 3 is two sliding clamping blocks 4, with through holes adapted to the fixed connecting rods 3, allowing them to slide horizontally along the fixed connecting rods 3. The side of the two sliding clamping blocks 4 that is close to each other, i.e. the side that is far away from the two sliding clamping blocks 4, is fixedly connected to a connecting spring 5. When the two sliding clamping blocks 4 are subjected to external force and move away from each other, the connecting spring 5 is stretched and generates elastic force. When the external force disappears, the connecting spring 5 pushes the two sliding clamping blocks 4 closer to each other by its own elastic force, thereby realizing the clamping function of the object.

[0034] Limiting components are fixedly connected to the outer side of each of the two sliding clamping blocks 4, i.e., the side closest to the two sliding clamping blocks 4 away from the two sliding clamping blocks 4. The limiting components include a fixed force-applying column 6, which is fixedly connected to the outer side of the two sliding clamping blocks 4, i.e., the side closest to the two sliding clamping blocks 4 away from the two sliding clamping blocks 4. A fixed block 7 is fixedly connected to the outer side of the fixed force-applying column 6. The fixed block 7 is cuboid in shape and has a through hole inside. The sliding limiting rod 8 can slide in the through hole. The sliding limiting rod 8 is slidably connected inside the fixed block 7, which can limit the movement range of the sliding clamping block 4 and prevent it from sliding excessively and detaching from the fixed connecting rod 3. It also provides a certain guiding effect for the movement of the sliding clamping block 4. The sliding limiting rod 8 is slidably connected to the outer side of the U-shaped sliding plate 2.

[0035] A drive assembly is fixedly connected to the outside of the CNC machine tool operating table 1. The drive assembly includes a first motor 9, which is fixedly connected to the outside of the CNC machine tool operating table 1. A rotating lead screw 10 is fixedly connected to the drive end of the first motor 9. When the first motor 9 is started, it drives the rotating lead screw 10 to rotate. Through threaded transmission, the U-shaped sliding plate 2 slides left and right along the fixed limit post 11. The outside of the rotating lead screw 10 is slidably connected to the inside of the U-shaped sliding plate 2.

[0036] Reference Figure 1 and Figure 3 The CNC machine tool operating table 1 is externally fixedly connected to a fixed connecting plate 12, which is a rectangular plate structure. The interior of the fixed connecting plate 12 is rotatably connected to the exterior of a rotating sector plate 19. The exterior of the rotating sector plate 19 is meshed with the exterior of a rotating gear 20. A switching mechanism is rotatably connected inside the fixed connecting plate 12. The switching mechanism includes a rotating gear 20, which is a circular structure. When the rotating gear 20 rotates, it drives the switching plate 22 to rotate via a second fixed connecting column 21, thereby completing the corresponding switching action. The exterior of the rotating gear 20 is rotatably connected to the interior of the fixed connecting plate 12. The bottom of the rotating gear 20 is fixedly connected to a second fixed connecting column 21, which is a cylindrical structure used for connection. The bottom of the second fixed connecting column 21 is fixedly connected to the switching plate 22, used to realize the switching operation of different working modes.

[0037] A power assembly is fixedly connected to the top of the fixed connecting plate 12. The power assembly includes a second motor 13. When the second motor 13 is started, it drives the rotating connecting column 14 and the rotating connecting plate 15 to rotate. At the same time, the sliding connecting column 16 slides in the groove of the first fixed connecting column 17. The bottom of the second motor 13 is fixedly connected to the top of the fixed connecting plate 12. The driving end of the second motor 13 is fixedly connected to the rotating connecting column 14. The rotating connecting column 14 has a cylindrical structure. The rotating connecting plate 15 is fixedly connected to the outside of the rotating connecting column 14. The sliding connecting column 16 is fixedly connected to the outside of the rotating connecting plate 15. The sliding connecting column 16 has a cylindrical structure. Its outside can slide in the groove inside the first fixed connecting column 17. The outside of the sliding connecting column 16 is slidably connected to the inside of the first fixed connecting column 17. The outside of the first fixed connecting column 17 is rotatably connected to the inside of the fixed connecting plate 12.

[0038] The fixed connecting plate 12 is internally fixedly connected to a first fixed connecting column 17. When the power component transmits power, the rotating perforated plate 18 and the rotating sector plate 19 rotate under the drive of the first fixed connecting column 17. The first fixed connecting column 17 is externally rotatably connected to a transmission component, which includes a rotating perforated plate 18 with holes inside to facilitate the sliding of the sliding connecting column 16. The rotating perforated plate 18 is internally rotatably connected to the outside of the first fixed connecting column 17, and the rotating sector plate 19 is externally rotatably connected to the first fixed connecting column 17, which can mesh with the external teeth of the rotating gear 20.

[0039] Working principle: First, by holding the fixed block 7, the two sliding clamping blocks 4 on the U-shaped sliding plate 2 are pulled outwards, causing the two sliding clamping blocks 4 to slide outside the fixed connecting rod 3. As the sliding clamping blocks 4 slide outwards, the connecting springs 5 ​​connecting the two sliding clamping blocks 4 are stretched, placing the required cutting tool on the CNC machine tool operating table 1. Then, using the elasticity of the connecting springs 5 ​​themselves, the two connecting springs 5 ​​slide towards the center, thereby fixing the cutting tool in the center, achieving rapid centering and eliminating the need for further adjustments. When the sliding clamping block 4 is moved to both sides, the sliding limit rod 8 is pulled out from the inside of the fixed block 7. When the sliding limit rod 8 slides the fixed block 7, the sliding limit rod 8 is lowered, so that the sliding clamping block 4 is restricted to both sides of the CNC machine tool operating table 1, which does not affect the operation of the CNC machine tool operating table 1. The first motor 9 is started to make the rotating screw 10 rotate. Because the rotating screw 10 has a bidirectional thread, the U-shaped sliding plate 2 can move vertically outside the CNC machine tool operating table 1, reducing the impact on the CNC machine tool operating table 1.

[0040] Before tool replacement, the tool to be replaced is placed in the holes at both ends of the switching plate 22. When tool replacement is required, the second motor 13 is started to drive the rotating connecting column 14 to rotate. Driven by the rotating connecting column 14, the rotating connecting plate 15 rotates. Driven by the rotating connecting plate 15, the sliding connecting column 16 rotates. Since the sliding connecting column 16 is in the hole inside the rotating hole plate 18, the force is converted into the swinging force of the rotating hole plate 18. Since the rotating hole plate 18 and the rotating sector plate 19 are connected by the first fixed connecting column 17, the rotating sector plate 19 rotates and drives the rotating gear 20 to rotate through the meshing connection. The rotating gear 20 transmits the rotational force to the switching plate 22 through the second fixed connecting column 21, thereby switching the tool model and facilitating the tool switching speed.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
