Description
Technical Field
[0001] This utility model belongs to the technical field of digital control machine tools, and specifically relates to an automatic chip blowing and cleaning mechanism for CNC machine tools. Background Technology
[0002] CNC machine tools are automated machine tools equipped with a program control system. Their production background is closely related to the manufacturing industry's demand for high-precision and high-efficiency production. With the development of modern industry, traditional machine tools can hardly meet the requirements of machining accuracy for complex parts and efficiency for large-scale production. CNC machine tools have emerged to meet this need. They integrate achievements from multiple fields such as computer technology and automatic control technology. Through pre-programmed procedures, they precisely control the relative movement between the cutting tool and the workpiece to achieve the machining of parts with various complex shapes. During the machining process of CNC machine tools, waste is generated. On the one hand, during cutting, the excess material removed from the workpiece forms cutting waste. For example, when turning a shaft part, the cutting tool will cut off the excess metal material into curled chips.
[0003] Currently, chip accumulation in the machining area of CNC machine tools can interfere with the normal cutting path of the tool and affect machining accuracy. Secondly, chip accumulation may damage the tool and shorten its life, because prolonged friction between the chip and the tool or chip stuck between the tool and the workpiece will accelerate tool wear. Furthermore, if the chip is not cleaned in time, it may be drawn into the moving parts of the machine tool, causing mechanical failures, such as jamming or wear of key components such as lead screws and guide rails.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0024] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0025] Example 1
[0026] Reference Figures 1-4 This is the first embodiment of the present invention, which provides an automatic chip removal mechanism for a CNC machine tool, comprising:
[0027] The CNC machine tool mechanism 100 includes an operating bed 101, a collection assembly 102 disposed at the bottom opening of the operating bed 101, a side baffle 103 fixedly installed on the top of the operating bed 101, and a ventilation slot 104 opened on the outside of the side baffle 103.
[0028] The chip blowing mechanism 200 includes an active dial 201 fixedly mounted on the outside of the operating bed 101 via a bearing seat, a drive motor 202 fixedly connected to the output end of the active dial 201, a grooved rod 203 sleeved on the protrusion of the active dial 201, an incomplete gear 204 fixedly mounted on the top of the grooved rod 203, and a toothed plate 205 meshing with the incomplete gear 204.
[0029] Among them, the drive motor 202 serves as the power source. Through the transmission relationship between the active dial 201, the slotted rod 203, the incomplete gear 204, and the toothed plate 205, the continuous rotational motion of the drive motor 202 is converted into the intermittent motion of the toothed plate 205. The meshing transmission between the incomplete gear 204 and the toothed plate 205 can blow away chips according to the cutting rhythm and effectively blow away the chips generated during the cutting process from the processing area. The side baffle 103 can prevent the chips generated during the cutting process from splashing to the side of the machine tool, thus protecting the surrounding environment of the machine tool and the safety of the operators. The ventilation slot 104 provides a channel for airflow during the chip blowing process, allowing the airflow generated during chip blowing to pass smoothly. This not only helps to blow the chips toward the collection component 102 but also ensures the air pressure balance inside the machine tool.
[0030] Specifically, the CNC machine tool mechanism 100 also includes a drive component 105 fixedly installed on the outside of the operating bed 101, a drive guide rail 106 adapted to be installed on the top of the drive component 105, a cutting component 107 sleeved on the outer surface of the drive guide rail 106, a rear baffle 108 fixedly installed on the top of the operating bed 101, and a groove plate 109 placed on the top of the operating bed 101.
[0031] In the CNC cutting process, precise motion control ensures that the cutting part 107 cuts along a preset trajectory, thereby guaranteeing machining accuracy. The drive component 105 and drive guide rail 106 can accurately control the position and direction of movement of the cutting part 107. The rear baffle 108 can prevent chips from splashing backward and together with the side baffle 103, it forms a relatively enclosed machining area. The groove plate 109 is placed on top of the operating bed 101, which can play a certain role in positioning and supporting the workpiece, and also helps to collect the chips generated during the machining process.
[0032] Furthermore, the chip blowing mechanism 200 also includes an air blowing pipe 206 fixedly installed on the top of the toothed plate 205, a ring 207 movably sleeved on the outer surface of the air blowing pipe 206, and a support rod 208 fixedly installed on the outside of the ring 207.
[0033] Among them, the air blowing pipe 206 serves as the air passage for blowing debris, guiding the airflow generated by the blower 102d to the location where debris needs to be blown away. The cooperation between the ring 207 and the support rod 208 can support and position the air blowing pipe 206. The bottom of the support rod 208 is fixed to the outside of the operating bed 101 by bolts, ensuring the stability of the air blowing pipe 206.
[0034] Preferably, the collection assembly 102 includes a housing 102a fixedly installed at the bottom of the operating bed 101, an exhaust port 102b opened on the outside of the housing 102a, a chip pusher 102c disposed in the inner cavity of the housing 102a, and a fan 102d fixedly installed on the outside of the housing 102a.
[0035] The housing 102a is located at the bottom opening of the operating bed 101. It provides a closed space for the collection of debris. This closed space can prevent debris from splashing everywhere and avoid debris from polluting the environment around the machine tool. It also facilitates the subsequent centralized processing of debris. The exhaust port 102b helps to form an air flow channel when the blower 102d is working. During the chip blowing process, the air carries the debris into the collection component 102. The exhaust port 102b can discharge the air in time, maintain the air pressure balance in the collection component 102, and ensure that the debris can be collected smoothly.
[0036] During use, the cutting part 107, under the coordinated action of the driving part 105 and the driving guide rail 106, performs cutting processing on the workpiece placed on the groove plate 109 according to a predetermined program. During this process, chips are generated. The chip blowing mechanism 200 starts to operate, the drive motor 202 starts, and drives the active dial 201 to rotate. The groove rod 203 at the protrusion of the active dial 201 rotates, which in turn causes the incomplete gear 204 fixed at the top of the groove rod 203 to rotate. The meshing of the incomplete gear 204 with the toothed plate 205 causes the toothed plate 205 to move intermittently. The air blowing pipe 206 fixed at the top of the toothed plate 205 also moves intermittently. The airflow generated by the blower 102d blows to the processing area through the air blowing pipe 206 and blows the chips to the bottom opening of the operating bed 101.
[0037] The side baffles 103 and rear baffles 108 on the top of the operating bed 101 prevent debris from splashing in all directions. The ventilation slots 104 on the outside of the side baffles 103 provide a channel for airflow. At the bottom opening of the operating bed 101, the fan 102d in the collecting assembly 102 generates suction to draw debris into the inner cavity of the housing 102a. The exhaust port 102b on the outside of the housing 102a maintains air pressure balance. The chip pusher 102c in the inner cavity starts to work. When the debris accumulates to a certain extent, the cylinder 102c-3 in the chip pusher 102c drives the pneumatic telescopic rod 102c-4 to drive the pusher plate 102c-5 to push the debris to the appropriate position. The air blowing pipe 206 is supported and positioned by the ring 207 and the support rod 208 to ensure that the chip blowing operation is carried out smoothly.
[0038] In summary, the chip blowing mechanism 200 can effectively blow the chips generated during cutting away from the machining area, preventing chips from accumulating in the machining area and affecting machining accuracy and damaging the cutting tools. The collection component 102 enables the chips to be collected in a concentrated manner, reducing the difficulty and workload of cleaning. The chip pusher 102c further facilitates the sorting of the collected chips, improves the efficiency of chip cleaning, optimizes the machining environment of the CNC machine tool, improves the machining efficiency of the CNC machine tool, reduces machine tool failures and machining errors caused by chip problems, and extends the service life of the machine tool.
[0039] Example 2
[0040] Reference Figure 1 , Figure 2 and Figure 3 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a chip pusher 102c for collecting blown debris.
[0041] Specifically, the chip pusher 102c includes a collection box 102c-1 movably inserted into the inner cavity of the housing 102a, a bracket 102c-2 fixedly installed on the outside of the collection box 102c-1, and a cylinder 102c-3 fixedly installed on the outside of the bracket 102c-2. The chip pusher 102c also includes a pneumatic telescopic rod 102c-4 adapted to be installed at the end of the cylinder 102c-3, a push plate 102c-5 fixedly installed at the end of the pneumatic telescopic rod 102c-4, and a cover plate 102c-6 hinged to the top of the collection box 102c-1.
[0042] The collection box 102c-1 is directly used to collect debris, allowing it to be collected in an orderly manner for easy periodic cleaning. When a large amount of debris is generated during processing, the collection box 102c-1 can accommodate it, preventing debris from accumulating inside the machine tool and affecting its normal operation. The cylinder 102c-3 drives the push plate 102c-5 to move via the pneumatic telescopic rod 102c-4. After a certain amount of debris has been collected, the push plate 102c-5 can push the debris in the collection box 102c-1 to a suitable position for centralized cleaning. When the collection box 102c-1 is almost full, the push plate 102c-5... Debris can be pushed to one side of the collection box 102c-1 to make room for continued collection. The cover can prevent debris from flying out of the top of the collection box 102c-1 during the blowing process. At the same time, when it is necessary to clean the collection box 102c-1, the cover 102c-6 can be opened for operation. The blower 102d is the key power source in the entire collection assembly 102 that drives debris into the collection box 102c-1. When the blowing mechanism 200 blows the debris to the vicinity of the bottom opening of the operating bed 101, the suction generated by the blower 102d draws the debris into the collection assembly 102, thereby realizing the collection of debris.
[0043] Furthermore, the bottom of the support rod 208 is fixedly installed on the outside of the operating bed 101 by bolts, and the end of the air blowing pipe 206 is provided with a flexible hose, which is connected to the air outlet of the blower 102d.
[0044] The flexible hose at the end of the air blowing pipe 206 is connected to the air outlet of the blower 102d. This flexible connection method facilitates the installation and adjustment of the position of the air blowing pipe 206 and ensures the effective transmission of airflow, thereby realizing the effective chip blowing operation for the chips generated during CNC cutting.
[0045] During use, the debris is drawn into the collection box 102c-1 inside the housing 102a by the suction force generated by the blower 102d. When the debris in the collection box 102c-1 accumulates to a certain extent, the cylinder 102c-3 on the outside of the bracket 102c-2 is activated, which extends the pneumatic telescopic rod 102c-4 and pushes the push plate 102c-5 to push the debris to a suitable position for centralized processing. The cover plate 102c-6 hinged to the top of the collection box 102c-1 prevents the debris from flying out.
[0046] In summary, the chip pusher 102 can effectively push the debris that falls into its interior to one side for centralized collection, while also effectively improving the utilization rate of the space inside the collection box 102c-1 and facilitating the subsequent processing of debris.
