[0022] In this embodiment, the numerical control machine tool body 1 serves as the main body of the machining equipment, and the workbench 2 thereon is used for fixing and supporting the parts to be machined. A stable machining environment is provided, which is the basic platform for chip generation and cleaning. The collecting groove 3 is opened on the numerical control machine tool body 1 and located below the workbench 2, and is used for receiving the chips generated in the cutting process. The chips are effectively collected to prevent them from falling directly into the machine tool, thereby reducing the damage to the accuracy of the machine tool. The collecting hopper 4 is fixedly installed in the collecting groove 3 to further concentrate and guide the chips. The chip collection efficiency is optimized to ensure that the chips can smoothly enter the next cleaning process. The guide hopper 5 is fixedly installed at the bottom of the collecting hopper 4 to guide the chips to the conveying pipe 6. The directional flow of the chips is ensured to reduce the possibility of blockage and leakage. The conveying pipe 6 is fixedly installed at the bottom of the guide hopper 5 and extends out of the numerical control machine tool body 1, serving as a channel for the transfer of chips to realize efficient transfer of the chips from the inside to the outside of the machine tool, thereby facilitating subsequent processing.

The chips are automatically cleaned to reduce manual intervention, improve production efficiency, and maintain the cleanliness and accuracy of the inside of the machine tool.
[0023] In further preferred embodiments of the present application, the conveying mechanism comprises an auger 8, a motor 9 and a discharge port 10. The auger 8 is rotatably installed in the conveying pipe 6 and is in contact with the inner wall of the conveying pipe 6. The motor 9 is fixedly installed on the conveying pipe 6, and the output shaft of the motor 9 is fixedly connected with the auger 8. The discharge port 10 is opened on the conveying pipe 6 and arranged outside the numerical control machine tool body 1.
[0024] In this embodiment, the auger 8 is rotatably mounted within the conveying pipe 6, in close contact with the inner wall of the conveying pipe 6. When the auger 8 rotates, its helical blades can push the debris forward along the conveying pipe 6.

[0026] In this embodiment, the collecting box 11 is arranged outside the numerical control machine tool body 1 and correspondingly arranged with the discharge port 10. This means that the debris discharged from the conveying pipe 6 will directly fall into the collecting box 11. The collecting box 11, as the final collection container of the debris, effectively avoids the scattering and accumulation of debris outside the machine tool, keeping the working environment clean. At the same time, since the collecting box corresponds directly with the discharge port, it ensures that the debris can smoothly enter the collecting box, improving the cleaning efficiency. A plurality of universal wheels 12 are fixedly installed at the bottom of the collecting box 11. These universal wheels enable the collecting box to move flexibly, facilitating position adjustment or emptying of debris when needed. The design of universal wheels greatly enhances the convenience and flexibility of the collecting box. The operator can easily move the collecting box to the designated position or push it to the open area for dumping and cleaning, thereby improving the working efficiency and comfort. A limiting mechanism is arranged on the numerical control machine tool body 1 to fix the collecting box 11 when needed. This can prevent the collecting box from moving or dumping during the operation of the machine tool, ensuring the stability and safety of the cleaning work.

During the machining process of the machine tool, even if subjected to vibration or impact, the collecting box can remain stable and immobile, avoiding accidental scattering of debris and possible damage. At the same time, this also provides more convenience and safety for the operator.
[0027] The further preferred embodiment of the utility model discloses, the stop gear includes U type block 13, two fixed blocks 14, movable block 15, locating block 16 and spring 17, U type block 13 is fixedly installed on the collection box 11, two fixed blocks 14 are all fixedly installed on numerical control machine tool body 1, movable block 15 is hinged between two fixed blocks 14, movable block 15 is correspondingly arranged with U type block 13, locating block 16 is fixedly installed between two fixed blocks 14, spring 17 is fixedly installed between locating block 16 and movable block 15.
[0028] In the embodiment, U type block 13 is fixedly installed on collection box 11. U type block 13 is used as the connecting component between collection box and stop gear, for cooperating with movable block 15 to realize fixing. Through the design of U type block, collection box can be conveniently installed on stop gear, and can be quickly released when needed. Two fixed blocks 14 are all fixedly installed on numerical control machine tool body 1. Fixed block is used as the hinge point of movable block 15, and provides stable installation basis. Through the installation of fixed block, the stability of stop gear is ensured, so that movable block 15 can smoothly rotate and position on it. Movable block 15 is correspondingly arranged with U type block 13, and cooperation or separation with U type block can be realized through rotation, so that collection box is fixed or released. The design of movable block makes stop gear have flexibility, and collection box can be quickly fixed or released according to need, improving work efficiency. Locating block 16 is fixedly installed between two fixed blocks 14. Locating block 16 is used as one of the fixed points of spring 17, and provides stable support for spring. Through the installation of locating block, it is ensured that spring can correctly exert elastic force and push movable block to position or reset. When U type block 13 needs to be fixed with numerical control machine tool body 1, collection box 11 is pushed to the direction of movable block 15, and the U type block 13 fixedly installed on collection box 11 abuts against movable block 15, so that the angle of movable block 15 changes, so that movable block 15 is placed between U type block 13, and collection box 11 is fixed, and spring 17 drives movable block 15 to reset. The design of spring makes stop gear have the function of automatic reset, improving the convenience and reliability of operation. Meanwhile, the elastic force of spring also ensures the stability of collection box when being fixed.
[0029] In the further preferred embodiment of the utility model, the numerical control machine tool body 1 is fixedly installed with electromagnet 18, the electromagnet 18 is correspondingly arranged with the U type block 13, and the electromagnet 18 is correspondingly arranged with the stop gear.
[0030] In this embodiment, electromagnet 18 is fixedly installed on the numerical control machine tool body 1 and is arranged correspondingly with the U-shaped block 13 and the limiting mechanism. Electromagnet 18 realizes the attraction of the U-shaped block 13 through electromagnetic force, thereby controlling the fixing and releasing of the collection box 11. When electromagnet 18 is powered on, it generates magnetic force to attract the U-shaped block 13, thereby assisting in fixing the collection box 11. When it is necessary to release the collection box, the power supply of electromagnet 18 is cut off, the magnetic force disappears, and the collection box can be released through other ways. The addition of electromagnet 18 makes the fixing and releasing of the collection box controllable through electrical signals, thereby improving the automation degree of the whole cleaning process. On the basis of spring 17, electromagnet 18 provides additional fixing force, thereby enhancing the stability of the collection box on the numerical control machine tool body 1. The operator can realize the fixing and releasing of the collection box without manually operating the limiting mechanism, thereby simplifying the operation process and improving the work efficiency. Due to the action of electromagnet 18, the direct contact and friction between the movable block 15 and the U-shaped block 13 are reduced, thereby prolonging the service life of the limiting mechanism and the collection box.
[0031] In further preferred embodiments of the utility model, the bottom of the collection groove 3 is fixedly installed with a drain pipe 19, the drain pipe 19 extends to the outside of the numerical control machine tool body 1, the bottom of the collection groove 3 is arranged in an inclined manner, and the drain pipe 19 is arranged at the lowest point in the collection groove 3.
[0032] In this embodiment, the drain pipe 19 is fixedly installed at the bottom of the collection groove 3 and extends to the outside of the numerical control machine tool body 1. The drain pipe 19 is used to drain the liquid (such as cooling liquid, cleaning water, etc.) accumulated in the collection groove 3, thereby preventing it from overflowing or remaining in the collection groove. When a certain amount of liquid is accumulated in the collection groove 3, the liquid will flow along the inclined bottom of the collection groove to the drain pipe 19 and be drained to the outside of the numerical control machine tool body through the drain pipe. The design of the drain pipe 19 ensures that the liquid in the collection groove can be drained in time, thereby avoiding damage to the numerical control machine tool body or the surrounding environment caused by liquid overflow. By draining the liquid in the collection groove in time, the cleanliness and dryness of the working area of the numerical control machine tool are maintained, which is conducive to the long-term stable operation of the equipment. The operator does not need to clean the liquid in the collection groove frequently, thereby reducing the difficulty and frequency of maintenance work. The bottom of the collection groove 3 is arranged in an inclined manner, so that the liquid accumulated therein can flow naturally to the lowest point where the drain pipe 19 is located. The inclined design accelerates the flow speed of the liquid, thereby improving the drainage efficiency. The inclined bottom of the collection groove makes the liquid flow to the drain pipe 19 faster, thereby reducing the drainage time. Since the liquid can flow smoothly to the drain pipe 19, the amount of residual liquid in the collection groove is greatly reduced, thereby reducing the cleaning problems caused by liquid residue.
[0033] In further preferred embodiments of the utility model, the conveying pipe 6 is arranged in an inclined manner, and the discharge port 10 is arranged at a position higher than the filter screen 7.
[0034] In this embodiment, the conveying pipe 6 is no longer kept in a horizontal or vertical state, but is set in an inclined state. The inclined conveying pipe helps the debris flow more smoothly under the action of gravity, reducing the possibility of blockage and accumulation. The inclined conveying pipe enables the debris to flow faster to the discharge port, improving the efficiency of the entire cleaning process. The inclined design helps to prevent debris from accumulating in the conveying pipe, reducing the risk of blockage. Due to the reduced possibility of blockage, the maintenance work of the conveying pipe is also simplified accordingly. The discharge port 10 is set higher than the filter screen 7, which means that the debris flowing out of the conveying pipe 6 needs to pass through the filter screen 7 first before flowing to the discharge port 10. The filter screen 7 is used to separate the liquid and solid parts in the debris, ensuring that only solid debris is discharged through the discharge port. By setting the discharge port higher than the filter screen, it can be ensured that all debris passing through the filter screen can be smoothly discharged, improving the separation effect of liquid and solid. Since the discharge port is higher than the filter screen, even if there is a small amount of liquid remaining in the debris, it is not likely to leak out of the discharge port, keeping the working area of the numerical control machine dry. The entire cleaning process is more smooth and efficient, reducing the cleaning difficulties caused by liquid leakage or debris accumulation.
[0035] In summary, compared with related technologies, by designing the collection groove, collection bucket, guide bucket, conveying pipe and other structures, efficient collection and transmission of debris generated during the machining process of the numerical control machine are realized, avoiding the accumulation of debris inside the machine, reducing the difficulty and frequency of cleaning work. Using a motor to drive the auger to rotate, combined with automatic components such as electromagnets, automatic control of the debris cleaning process is realized, reducing manual intervention and improving production efficiency and cleaning efficiency. By cleaning the debris inside the machine in a timely manner, damage to the machine precision caused by debris is avoided, prolonging the service life of the machine and improving the machining quality. The filter screen is provided on the conveying pipe to filter the liquid such as coolant in the debris, preventing the liquid from entering the conveying system, reducing environmental pollution, and also saving the use amount of coolant. The universal wheels are installed at the bottom of the collection box for easy movement and emptying, and the limiting mechanism and electromagnet are provided to make the fixing and releasing of the collection box more convenient, improving the work efficiency and comfort of the operator.
