Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool magazine technology, and in particular to a CNC machine tool magazine structure with rapid tool changing capability. Background Technology

[0002] The tool magazine of a CNC machine tool is a key functional component for achieving automated machining. It can store various types of tools of different specifications and uses, providing tool reserves for complex machining tasks. By working closely with the machine tool control system, the tool magazine can accurately and quickly select and change tools according to program instructions, greatly reducing the non-cutting time of the machine tool, improving equipment utilization and production efficiency. With stable tool clamping and precise positioning, the tool magazine ensures that the tool maintains the correct position and posture during machining, effectively reducing vibration and offset, and ensuring machining accuracy and surface quality. It plays an indispensable role in achieving efficient and high-precision automated machining.

[0003] In the efficient and automated machining process of CNC machine tools, the tool magazine, as a key component, bears the important responsibility of storing and quickly switching tools. Its performance directly affects machining efficiency and quality. Under long-term operation, friction is easily generated between the tool and the tool head where the tool is placed. During the tool changing process, the tool needs to be positioned and clamped on the tool head. These frequent actions cause the contact parts between the tool and the tool head to be constantly subjected to mechanical forces, which leads to friction, accelerates tool wear, and significantly shortens tool life. This not only increases the frequency of tool replacement but may also lead to a decrease in machining accuracy due to tool wear, affecting product quality.

[0004] Therefore, it is necessary to invent a CNC machine tool magazine structure that enables rapid tool changing to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a CNC machine tool tool magazine structure with rapid tool changing capability, in order to solve the problems mentioned in the background art. In the efficient and automated machining process of CNC machine tools, the tool magazine, as a key component, bears the heavy responsibility of storing and quickly changing tools. Its performance directly affects machining efficiency and quality. Under long-term operation, friction is easily generated between the tool and the tool turret where the tool is placed. During the tool changing process, the tool needs to be positioned and clamped on the tool turret. These frequent actions cause the contact parts between the tool and the tool turret to be constantly subjected to mechanical forces, thereby causing friction, which aggravates tool wear and significantly shortens tool life. This not only increases the frequency of tool replacement, but may also lead to a decrease in machining accuracy due to tool wear, affecting product quality.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a CNC machine tool tool magazine structure with quick tool changing, comprising a base plate and a movable plate, wherein the movable plate is slidably connected to the top of the base plate, and a plurality of placement slots are evenly provided at the front end of the movable plate, wherein a clamping arc ring is provided on the inner side of the placement slot, and a plurality of liquid spraying nozzles are provided at the front end of the clamping arc ring, wherein a connecting pipe is fixedly connected to the top end of the clamping arc ring, and an interface is fixedly connected to the top end of the connecting pipe;

Detailed Implementation

[0024] 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.

[0025] Please see the appendix Figure 1 - Appendix Figure 5 A CNC machine tool tool magazine structure with quick tool changing includes a base plate 1 and a movable plate 2. The movable plate 2 is slidably connected to the top of the base plate 1. Multiple placement slots 24 are evenly opened at the front end of the movable plate 2. A clamping arc ring 23 is provided on the inner side of the placement slot 24. Multiple liquid spraying ports 234 are opened at the front end of the clamping arc ring 23. A connecting pipe 232 is fixedly connected to the top end of the clamping arc ring 23. An interface 233 is fixedly connected to the top end of the connecting pipe 232.

[0026] The top of the movable plate 2 is fixedly connected to a liquid storage tank 21. The top of the liquid storage tank 21 is equipped with a pressurizing air pump 211 and a liquid inlet 213. Multiple liquid outlets 212 are symmetrically arranged on both sides of the liquid storage tank 21, and the liquid outlets 212 are correspondingly arranged with the connecting pipe 232.

[0027] Specifically, by setting a clamping arc ring 23, the cutting tool is provided with a circular groove corresponding to the clamping arc ring 23, so that the cutting tool can be clamped on the outside of the clamping arc ring 23. By setting a clamping arc ring 23, multiple liquid spraying ports 234 are evenly arranged on the inner side of the clamping arc ring 23. The top of the clamping arc ring 23 is provided with a connecting pipe 232 and an interface 233, which facilitates communication with the drain port 212 through a hose. Thus, after the CNC machine tool cutting tool is clamped on the outside of the clamping arc ring 23, the pressure is applied to the inside of the liquid storage tank 21 by the pressurizing air pump 211, so that the lubricating fluid is discharged into the connecting pipe 234 through the drain port 212. The lubricating oil is sprayed from the nozzle 234 onto the inner side of the clamping arc ring 23 and the inner side of the clamping arc ring 23. This effectively lubricates the cutting tool and prevents it from being damaged by prolonged friction with the clamping arc ring 23. The pressurizing air pump 211 can be controlled by an external controller. When a cutting tool is placed on the clamping arc ring 23, the pressurizing air pump 211 can be activated to pressurize the liquid storage tank 21. This allows the lubricating oil in the liquid storage tank 21 to enter the inner side of the connecting pipe 232 through the drain port 212 and the hose. The inner side of the clamping arc ring 23 is hollow and connected to the nozzle 234, thus effectively spraying the lubricating oil from the nozzle 234.

[0028] Please see the appendix Figure 3 and Figure 5Both ends of the clamping arc ring 23 are fixedly connected with a locking block 231. The inner side of the locking block 231 is provided with a second mounting hole 235. The two sides of the placement groove 24 are symmetrically provided with positioning grooves 242, which are corresponding to the locking block 231. The inner side of the positioning groove 242 is provided with a third mounting hole 243. The top of the placement groove 24 is provided with a locking groove 241, which is corresponding to the connecting pipe 232.

[0029] Specifically, by fixing locking blocks 231 to both ends of the clamping arc ring 23, a second mounting hole 235 is provided on the inner side of the locking block 231, and positioning grooves 242 are symmetrically arranged on both sides of the placement groove 24, corresponding to the locking blocks 231. A third mounting hole 243 is provided on the inner side of the positioning groove 242, and a locking groove 241 is provided at the top of the placement groove 24, corresponding to the connecting pipe 232. Thus, when the clamping arc ring 23 needs to be installed, the clamping arc ring 23 is placed inside the placement groove 24. At this time, the locking block 231 will be inserted into the inner side of the positioning groove 242, and the connecting pipe 232 will be inserted into the inner side of the locking groove 241. The second mounting hole 235 and the third mounting hole 243 are aligned, and the connecting pipe 232 can be fixedly connected to the inner side of the positioning groove 242 with bolts, thus fixing the clamping arc ring 23 inside the placement groove 24.

[0030] Please see the appendix Figure 4 Multiple mounting ears 12 are evenly provided at the top of the rear end of the substrate 1. A first mounting hole 121 is provided on the inner side of the mounting ear 12. Multiple arc-shaped grooves 15 are evenly provided at the front end of the substrate 1. The arc-shaped grooves 15 are positioned corresponding to the positions of the clamping arc-shaped ring 23.

[0031] Specifically, by setting a mounting ear 12, a first mounting hole 121 is provided on the inner side of the mounting ear 12. The mounting ear 12 can be fixedly connected to the corresponding position of the CNC machine tool by passing through the first mounting hole 121 with bolts, thereby effectively installing and fixing the base plate 1. By setting an arc groove 15, the arc groove 15 is set in a position corresponding to the clamping arc ring 23, so that the tool can be set inside the arc groove 15. When the tool is clamped on the outside of the clamping arc ring 23, it will also be set in the arc groove 15. The setting of the arc groove 15 can effectively ensure that it will not affect the placement of the tool.

[0032] Please see the appendix Figure 1 and Figure 4 The substrate 1 has symmetrical first through holes 13 on its inner side, and a second through hole 14 is formed between the two first through holes 13. A cylinder 11 is fixedly connected to the rear end of the substrate 1, and the output end of the cylinder 11 passes through the second through hole 14 and is fixedly connected to the movable plate 2.

[0033] Specifically, by setting a first through hole 13, which is correspondingly set with the guide rod 22, the guide rod 22 can slide inside the first through hole 13. By setting a second through hole 14, the cylinder 11 is fixedly connected to the rear end of the base plate 1. The output end of the cylinder 11 passes through the second through hole 14 and is fixedly connected to the moving plate 2, so that the cylinder 11 can effectively drive the moving plate 2 to move.

[0034] Please see the appendix Figure 1 , Figure 2 and Figure 4 The rear end of the movable plate 2 is symmetrically and fixedly connected with a guide rod 22. The guide rod 22 is slidably disposed inside the first through hole 13. The end of the guide rod 22 is fixedly connected with a limit block 222. The limit block 222 is disposed on the outside of the base plate 1. A spring 221 is disposed on the outside of the guide rod 22. The spring 221 is disposed between the base plate 1 and the movable plate 2.

[0035] Specifically, by setting a guide rod 22, which is slidably connected to the inner side of the first through hole 13, the setting of the limiting block 222 can effectively limit the movement of the guide rod 22. The spring 221 is set on the outer side of the guide rod 22 and between the base plate 1 and the moving plate 2. Thus, when the moving plate 2 moves, the guide rod 22 slides on the inner side of the first through hole 13, which can effectively improve the stability of the movement of the moving plate 2. The setting of the spring 221 can effectively buffer the movement between the base plate 1 and the moving plate 2. In specific use, when the cylinder 11 pushes the moving plate 2 forward, the guide rod 22 slides on the inner side of the first through hole 13, which can effectively improve the stability of the movement of the moving plate 2. The limiting block 222 can effectively prevent the guide rod 22 from sliding out of the base plate 1.

[0036] The working principle of this utility model is as follows: In specific use, the tool to be replaced is slidably attached to the clamping arc ring 23. At this time, the pressurizing air pump 211 is started. The pressurizing air pump 211 can be controlled by an external controller. The pressurizing air pump 211 pressurizes the liquid storage tank 21, so that the lubricating oil in the liquid storage tank 21 will enter the inner side of the connecting pipe 232 through the drain port 212 and the hose. The inner side of the clamping arc ring 23 is hollow and connected to the spray port 234, so that the lubricating oil can be effectively sprayed out from the spray port 234, effectively lubricating the clamping part of the tool.

[0037] The starting cylinder 11 drives the moving plate 2 forward, which in turn moves the cutting tool. At this time, the cutting head on the CNC machine tool moves above the cutting tool and connects with it. It then moves forward to slide the cutting tool off the clamping arc ring 23. After that, the cylinder 11 drives the moving plate 2 back to the top of the base plate 1, which facilitates subsequent tool changing.

[0038] 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.
