Description

Technical Field

[0001] The utility model relates to the technical field of numerical control machine tools, in particular to a numerical control machine tool with easy tool replacement. Background Technique

[0002] A numerical control machine tool, that is, a numerically controlled machine tool, controls the movement of the machine tool through a built-in numerical control system. The numerical control system can logically process a program with control codes or other symbolic instructions. After decoding, it is represented by coded numbers and input into the numerical control device through an information carrier. After being processed by the numerical control device, various control signals are sent out to control the machine tool to automatically process parts according to the shape and size required by the drawing.

[0003] For example, a numerical control machine tool with the publication number CN112846930A discloses, specifically, including a spindle box, a spindle rotatably mounted axially on the spindle box, and a driving motor arranged in the spindle box for driving the spindle to rotate; the end of the spindle extending out of the spindle box is used for mounting a tool, and at least one spray port is arranged on the same side end face of the spindle box where the end of the spindle extending out of the spindle box is located, and a cutting fluid flow channel communicated with the spray port is arranged in the spindle box. In this application, by spraying the cutting fluid from the end face of the spindle box, the sprayed cutting fluid can be stably concentrated at the position where the tool is mounted at the end of the spindle extending out of the spindle box, so as to avoid the problem that the cutting fluid cannot be sprayed to the contact position between the tool and the workpiece due to the change of the angular orientation between the power head and the workpiece, thereby improving the usability.

[0004] The tool replacement of the existing numerical control machine tool is not convenient. If the tool replacement process is cumbersome and takes a long time, this will lead to an increase in the downtime of the machine tool, thereby reducing the production efficiency. On the other hand, the inconvenient tool replacement method may require more manual operations or complex steps, increasing the labor intensity and working difficulty of the operator. For this reason, we propose a numerical control machine tool with easy tool replacement. Content of the Utility Model

[0022] Please refer to Figures 1-4 , the present invention provides a technical solution for a numerically controlled machine tool with easily replaceable tools:

[0023] It includes a body 1. A cavity 2 is provided inside the body 1. A platform 3 is provided inside the cavity 2. A bottom shaft 4 is fixedly installed at the center of the bottom of the platform 3. The bottom shaft 4 is rotatably installed inside the cavity 2. An active seat 5 is provided at the upper end inside the cavity 2. Two guide rods 6 arranged at intervals penetrate through the active seat 5. The ends of the guide rods 6 are fixedly connected to the inner side of the cavity 2. A tool holder 7 is provided inside the cavity 2. The tool holder 7 is located below the active seat 5. Two telescopic rods 8 arranged at intervals are fixedly installed on the active seat 5. The output ends of the telescopic rods 8 are fixedly connected to the tool holder 7. A rotating shaft 9 is rotatably installed inside the tool holder 7. Two circular plates 10 arranged at intervals are fixedly installed on the rotating shaft 9. A blade 11 is arranged between the two circular plates 10. The blade 11 is connected to the circular plate 10 by screws. A driven wheel 12 is fixedly installed at the end of the rotating shaft 9. A servo motor 13 is fixedly installed on the tool holder 7. A driving wheel 14 is fixedly installed at the output shaft end of the servo motor 13. The driving wheel 14 meshes with the driven wheel 12. A linear motor 15 is fixedly installed inside the cavity 2. The slider of the linear motor 15 is fixedly connected to the active seat 5.

[0024] Among them, as Figure 3 and Figure 4 shown, the inside of the tool holder 7 is hollow. A liquid inlet pipe 16 is fixedly installed on the tool holder 7. A sealing plug is equipped at the liquid inlet pipe 16. A pressure pump 17 is fixedly installed on the tool holder 7. The pressure pipe of the pressure pump 17 communicates with the inner cavity of the tool holder 7. Nozzles 18 are fixedly installed at both ends of the bottom of the tool holder 7. The nozzles 18 are arranged facing the blade 11. A plurality of pressing plates 19 distributed in a circumferential array are arranged above the platform 3. A plurality of electric telescopic rods 20 are fixedly installed on the platform 3. The electric telescopic rods 20 are respectively fixedly connected to the pressing plates 19. A motor 21 is fixedly installed inside the body 1. The output shaft of the motor 21 is fixedly connected to the center of the bottom of the platform 3. Flow guiding grooves 22 are opened on both sides of the cavity 2. Storage grooves 23 are fixedly installed on both sides of the body 1.

[0025] The working principle of the present utility model is as follows: Place the workpiece on the platform 3, drive the pressing plate 19 to press on the workpiece through the electric telescopic rod 20, so that the workpiece remains fixed during the processing. Drive the driving wheel 14 to rotate through the servo motor 13, the driving wheel 14 drives the driven wheel 12 to rotate, which can drive the rotating shaft 9 and the blade 11 to rotate synchronously. The blade 11 rotates to process the workpiece. Drive the tool holder 7 to move through the telescopic rod 8, which can drive the blade 11 to move towards the workpiece.

By setting the detachable connection between the wafer 10 and the blade 11, the blade 11 can be replaced and the replacement operation is convenient. The operator can complete the tool change operation in a short time, reducing the downtime, thereby improving the production efficiency. The simplified tool change process reduces the physical consumption and energy input of the operator, making the tool change work easy and fast. This helps to reduce the labor intensity of the operator and improve the work comfort.

[0026] By adding cutting fluid into the inner cavity of the tool holder 7, pressurize the inner cavity of the tool holder 7 through the pressure pump 17, and spray the cutting fluid from the nozzle 18. The cutting fluid can be sprayed on the surface of the blade 11. During the processing of the workpiece, the blade 11 is lubricated and cooled by the cutting fluid. The lubricant in the cutting fluid can reduce the frictional resistance between the blade and the workpiece, reduce the cutting force, thereby improving the processing efficiency. After reducing the frictional resistance, the cutting force is also correspondingly reduced, which helps to reduce the power demand of the machine tool and reduce the energy consumption. The lubrication effect can reduce the thermal deformation and wear generated by the blade during cutting, thereby preventing burrs from appearing on the edge and improving the accuracy of the processed surface.
