Description

Technical Field

[0001] This utility model belongs to the field of mechanical processing equipment technology, specifically a parts cutting device for metal processing. Background Technology

[0002] With the development of metal processing technology, various parts cutting devices have been widely used in industrial production. However, these devices still have some problems in actual use. For example, existing cutting devices often struggle to adaptively adjust the grooving density when dealing with shaft parts of different diameters or stepped structures, and the coordination between tool feed and traverse movement is poor, resulting in low cutting efficiency and low automation. In addition, some devices have complex structures and high maintenance costs, making it difficult to meet the demands of modern manufacturing for efficient, intelligent, and stable cutting equipment.

[0003] A search revealed a metalworking parts cutting device with publication number CN119681769B, published on May 16, 2025. This patent proposes a cutting device comprising an adaptive spacing transverse movement mechanism, a variable depth grooving mechanism, and a clamping mechanism. It uses a unidirectional transmission component to drive an opening and closing control push rod, achieving intermittent driving of the crossbeam body. A diameter sensing mechanism adaptively adjusts the sliding amplitude, thereby automatically adjusting the grooving density. While this solution improves upon structural simplification and automated adjustment, its adaptive control relies on a mechanical sensing structure, resulting in limited response sensitivity. This makes it prone to adjustment lag or misjudgment when dealing with frequently changing workpiece dimensions. Furthermore, the device lacks an effective cooling or chip removal system, which could lead to tool overheating and decreased grooving quality during prolonged operation, affecting machining accuracy and equipment lifespan.

[0004] A search revealed a laser cutting device for metal parts, publication number CN118720458B, published on January 28, 2025. This device employs a laser cutting head with a cooling assembly, cooling before cutting to ensure stable laser head operating temperature and improve cutting efficiency and lifespan. Its structure includes a protective shell, guide components, and an adjustment mechanism, providing a certain level of safety and stability. However, this device is primarily designed for laser cutting of flat sheet metal and lacks adaptability to complex geometric shapes such as stepped shafts, making it unable to achieve continuous adaptive grooving in areas with varying diameters. Furthermore, its adjustment mechanism relies on manual or preset program settings for the cutting position and lacks the function of feedback adjustment based on real-time workpiece characteristics, making it difficult to meet the integrated processing requirements of high-precision, multi-variable parts.

[0005] The aforementioned problems indicate that existing metal parts cutting devices generally suffer from insufficient adaptability, poor motion coordination, and weak environmental adaptability when dealing with complex structural parts (such as stepped shafts), making it difficult to simultaneously meet the requirements of high efficiency, precision, and intelligent control. Therefore, there is an urgent need to provide a new type of metal processing parts cutting device to overcome the problems of inflexible adjustment of grooving density for parts of different diameters and the lack of intelligent collaborative control in the cutting process, thereby improving the overall level of automation and adaptability in the processing.

[0025] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Specific implementation examples are given below.

[0027] This utility model provides a parts cutting device for metal processing, the specific implementation of which is as follows: like Figure 1As shown, the entire device consists of a base assembly, a high-energy beam cutting assembly, a cooling and chip removal assembly, and an adaptive adjustment assembly. The base assembly includes a base plate 1, support columns 2, a slide rail 3, and a fixing clamp 4. The base plate 1 is the fundamental component of the entire device, with two support columns 2 symmetrically fixed to its top. A slide rail 3 is horizontally installed between the support columns 2. The fixing clamp 4 is slidably connected to the outer wall of the slide rail 3 and can move along the axial direction of the slide rail 3. The fixing clamp 4 has a clamping groove 5 inside, and elastic pads 6 are distributed on the inner wall of the clamping groove 5 to provide cushioning and prevent damage to the workpiece surface when clamping it. A drive rack 7 is fixed to one outer wall of the fixing clamp 4. The drive rack 7 meshes with the adjusting gear 21 in the adaptive adjustment assembly to adjust the position of the fixing clamp 4.

[0028] The high-energy beam cutting assembly includes a laser emitter 8, a focusing lens group 9, a moving platform 10, and a transverse guide rod 11. For example... Figure 3 As shown, a focusing lens assembly 9 is installed at the output end of the laser emitter 8. The bottom of the focusing lens assembly 9 is fixedly connected to the top of the moving platform 10 via a positioning pin 26 to ensure that the relative position between the focusing lens assembly 9 and the moving platform 10 remains stable. The focusing lens assembly 9 contains multiple layers of lenses, which are fixedly connected by a snap-fit ​​structure to ensure a tight fit between the lenses. The two sides of the moving platform 10 are symmetrically slidably connected to the outer wall of the transverse guide rod 11. The two ends of the transverse guide rod 11 are respectively fixed to the inner side wall of the support column 2, thereby providing guidance for the horizontal movement of the moving platform 10. A cutting head 12 is installed at the bottom of the moving platform 10. A protective cover 13 is fitted onto the outer wall of the cutting head 12. The protective cover 13 is used to prevent debris generated during the cutting process from flying and causing injury to the operator.

[0029] The cooling and chip removal assembly includes a coolant nozzle 14, a chip removal channel 15, a chip collection box 16, and a drain pump 17. For example... Figure 4 As shown, the top of the coolant nozzle 14 is fixed to the bottom of the moving platform 10, and the outlet of the coolant nozzle 14 faces the cutting area of ​​the cutting head 12. A flow divider 27 is provided at the outlet of the coolant nozzle 14, and multiple flow divider holes 28 are distributed on the surface of the flow divider 27. The diameter of the flow divider holes 28 gradually decreases along the coolant flow direction to achieve uniform coolant flow rate. One end of the chip removal channel 15 is connected to the top of the base plate 1, and the other end extends into the interior of the chip collection box 16, which is used to guide the chips and waste liquid generated during the cutting process into the chip collection box 16. A drain pump 17 is installed on one side of the chip collection box 16, and the output end of the drain pump 17 is connected to the coolant nozzle 14 through a pipe to realize the recycling of coolant.

[0030] The adaptive adjustment component includes a detection module 18, a control unit 19, a stepper motor 20, and an adjusting gear 21. The bottom of the detection module 18 is fixed to one side of the base plate 1. The detection module 18 includes a displacement sensor 29 and a data analysis unit 30. The probe of the displacement sensor 29 faces the clamping slot 5 of the fixed fixture 4, used to acquire real-time changes in the geometric features of the workpiece. The output end of the data analysis unit 30 is connected to the input end of the control unit 19. The control unit 19 adjusts the speed and direction of the stepper motor 20 based on the detection data. The top of the output shaft of the stepper motor 20 is fixed with the adjusting gear 21, which meshes with the drive rack 7 on the fixed fixture 4. Thus, the rotation of the stepper motor 20 drives the drive rack 7 to move, thereby adjusting the position of the fixed fixture 4.

[0031] Pressure sensors 34 are distributed on the inner wall of the clamping groove 5 of the fixed fixture 4. The signal output terminal of the pressure sensor 34 is connected to the input terminal of the control unit 19 to monitor the clamping force of the workpiece and feed the data back to the control unit 19. The control unit 19 adjusts the clamping force of the fixed fixture 4 according to the feedback data of the pressure sensor 34 to prevent the workpiece from deforming due to excessive clamping force or loosening due to insufficient clamping force.

[0032] An operation panel 31 is provided on the top side of the base assembly. A display screen 32 and function buttons 33 are mounted on the surface of the operation panel 31. The signal input terminal of the display screen 32 is connected to the output terminal of the control unit 19, used to display the detection data of the detection module 18 and the equipment operating status in real time. Operators can use the function buttons 33 to set parameters and control the operation of the equipment.

[0033] In actual operation, the workpiece to be cut is first placed on the guide plate 23 through the material inlet 22 and slides into the clamping groove 5 of the fixed fixture 4. The elastic pad 6 in the fixed fixture 4 initially clamps the workpiece, while the pressure sensor 34 monitors the clamping force in real time and feeds the data back to the control unit 19. The control unit 19 adjusts the clamping force of the fixed fixture 4 according to the feedback data to ensure that the workpiece is firmly clamped and will not deform due to excessive clamping force. Subsequently, the displacement sensor 29 in the detection module 18 scans the geometric features of the workpiece and transmits the data to the data analysis unit 30. The data analysis unit 30 processes the data and transmits it to the control unit 19. The control unit 19 calculates the optimal cutting parameters according to the preset algorithm and drives the stepper motor 20 to rotate. The stepper motor 20 drives the drive rack 7 to move through the adjusting gear 21, thereby adjusting the position of the fixed fixture 4 so that the cutting head 12 maintains the optimal cutting distance with the workpiece surface.

[0034] Before the cutting operation begins, coolant nozzles 14 in the cooling and chip removal assembly pre-spray coolant, forming a coolant film in the cutting area of ​​the cutting head 12 to reduce the impact of heat generated during cutting on the workpiece. Subsequently, the laser emitter 8 in the high-energy beam cutting assembly is activated, and the laser beam is focused by the focusing lens group 9 before cutting the workpiece through the cutting head 12. The chips and waste liquid generated during cutting are guided to the chip collection box 16 through the chip removal channel 15. The coolant in the chip collection box 16 is circulated back to the coolant nozzles 14 by the drain pump 17, thus achieving coolant recycling. Throughout the cutting process, the detection module 18 monitors the changes in the geometric features of the workpiece in real time and feeds the data back to the control unit 19. The control unit 19 dynamically adjusts the cutting parameters based on the real-time data to ensure cutting accuracy and efficiency.

[0035] The specific embodiments of this utility model have been described in detail above. The connection relationships, positional relationships, and mutual cooperation relationships between the various components have been fully explained, enabling those skilled in the art to implement the technical solution of this utility model based on the above content. In order to better enable those skilled in the art to fully understand and implement this utility model, the specific implementation principle of this utility model is further explained below in conjunction with a specific application scenario.

[0036] First, the operator places the stepped shaft part to be processed onto the guide plate 23 through the material inlet 22, and slides it into the clamping groove 5 of the fixed fixture 4. During this process, the tilt angle of the guide plate 23 can be adjusted by rotating the angle adjustment bolt 24 to ensure that the workpiece can be smoothly introduced into the clamping groove 5. The elastic pad 6 in the fixed fixture 4 forms an initial clamping force on the workpiece, while the pressure sensor 34 monitors the clamping force in real time and feeds the data back to the control unit 19. The control unit 19 dynamically adjusts the clamping force of the fixed fixture 4 according to the feedback data to avoid damage to the workpiece surface due to excessive clamping force or loosening of the workpiece due to insufficient clamping force.

[0037] Subsequently, the displacement sensor 29 in the detection module 18 scans the geometric features of the workpiece to obtain information on the changes in the diameter of each segment of the workpiece. This data is transmitted to the data analysis unit 30, processed, and then sent to the control unit 19. The control unit 19 calculates the optimal cutting parameters according to a preset algorithm, including the distance between the cutting head 12 and the workpiece surface, the cutting speed, and the coolant flow rate. The control unit 19 drives the stepper motor 20 to rotate, and the stepper motor 20 drives the drive rack 7 to move through the adjusting gear 21, thereby adjusting the position of the fixed fixture 4 on the slide rail 3 so that the cutting head 12 always maintains the optimal cutting distance from the workpiece surface.

[0038] Before the cutting operation begins, the coolant nozzles 14 in the cooling and chip removal assembly pre-spray coolant, forming a uniform coolant film in the cutting area of ​​the cutting head 12. A flow divider 27 at the outlet of the coolant nozzles 14 uses multiple flow dividers 28 to uniformly distribute the coolant flow rate, effectively covering the entire cutting area. After the laser emitter 8 in the high-energy beam cutting assembly is activated, the laser beam is focused by the focusing lens group 9 and cuts the workpiece through the cutting head 12. The multi-layered lenses inside the focusing lens group 9 are tightly fitted together by a snap-fit ​​structure, ensuring the focusing accuracy and stability of the laser beam. The chips and waste liquid generated during the cutting process are guided to the chip collection box 16 through the chip removal channel 15. The coolant in the chip collection box 16 is circulated back to the coolant nozzles 14 by the drain pump 17, achieving efficient utilization of the coolant.

[0039] Throughout the cutting process, the detection module 18 continuously monitors changes in the workpiece's geometric features and feeds real-time data back to the control unit 19. The control unit 19 dynamically adjusts the cutting parameters based on the real-time data, for example, by further fine-tuning the position of the fixing fixture 4 via the stepper motor 20, or adjusting the flow rate of the coolant nozzle 14 to adapt to the cutting requirements of different diameter sections. This real-time feedback mechanism ensures the accuracy and efficiency of the cutting process, especially when dealing with stepped shaft parts with multiple diameter variations, enabling continuous adaptive grooving.

[0040] In addition, the display screen 32 on the operation panel 31 displays the detection data of the detection module 18 and the operating status of the equipment in real time. The operator can set parameters and control the operation of the equipment through the function keys 33. For example, when it is necessary to adjust the cutting depth or coolant flow rate, the operator can input new parameter values ​​through the function keys 33, and the control unit 19 will recalculate and adjust the working status of the relevant components according to the input values.

[0041] Through the above steps, the cutting device of this invention can achieve efficient and precise processing of parts with complex geometries, and is especially suitable for the continuous grooving requirements of multi-segment diameter variations in stepped shaft parts. The coordinated operation of the base assembly, high-energy beam cutting assembly, cooling and chip removal assembly, and adaptive adjustment assembly not only significantly improves cutting efficiency and automation level, but also effectively reduces the risk of thermal deformation and extends the service life of the equipment.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
