Description

Technical Field

[0001] The present invention mainly relates to the technical field of automobile parts processing, and in particular to an automobile parts cutting tool and a cutting method. Background Art

[0002] In the production and processing of automotive parts, cutting of materials is an important part of the processing. The cutting tools of automotive parts materials can cut the materials in the automobile manufacturing process to obtain the processed materials with the required shape, size and precision.

[0003] During high-speed cutting of automotive parts, the heat generated by friction between the cutting head and the workpiece causes the tool temperature to rise sharply, reducing the hardness of the tool material, which directly leads to increased edge wear and inaccurate cutting. Traditional cooling solutions often use a single air-cooling or water-cooling structure. Air cooling alone is limited by the low thermal conductivity of air, and its cooling efficiency plummets when the cutting head rotates too fast. Traditional water-cooling systems, however, are prone to entanglement during the movement of the screw module due to their rigid water pipe layout. Furthermore, insufficient coolant flow can hinder heat exchange efficiency and meet the requirements of continuous processing. Summary of the Invention

[0005] The technical solution adopted by the present invention to solve the above technical problems is:

[0007] The position adjustment mechanism includes a y / z axis translation assembly connected to the cutting table body, and an x ​​axis translation assembly connected to the execution end of the y / z axis translation assembly;

[0008] The x-axis translation assembly includes a first screw module connected to the y / z-axis translation assembly, an execution end of the first screw module is connected to a heat dissipation shell, and the heat dissipation shell is connected to the cutting head.

[0009] Furthermore, the y / z-axis translation assembly includes a second screw module connected to both sides of the cutting table, a slider connected to the execution end of the second screw module, and a third screw module connected to the upper surface of the slider, and the execution end of the third screw module is connected to the first screw module.

[0010] Furthermore, the outer surfaces of both ends of the first screw module are connected to a first U-shaped connecting piece, the outer surfaces of both sides of the third screw module are connected to a second U-shaped connecting piece, and an accordion-type shielding piece is connected between the first U-shaped connecting piece and the second U-shaped connecting piece at the same end.

[0011] Furthermore, two ends of one side surface of the first screw module are connected with hollow protrusions, and a corrugated water pipe is connected between the hollow protrusion and the third screw module.

[0012] Furthermore, a corrugated air duct is provided on the outside of the corrugated water pipe, and the corrugated air duct is connected between the hollow protrusion and the third screw module.

[0013] Furthermore, the interior of the hollow protrusion is connected to a water pipe, which is connected to the corrugated water pipe on the same side. The outside of the water pipe is connected to an air duct, and one end of the air duct extending to the outside is connected to a fan, which is connected to the outer surface of the hollow protrusion.

[0014] Furthermore, a heat dissipation air duct is provided on the shell of the heat dissipation shell, a heat dissipation water pipe is connected to the interior of the heat dissipation air duct, the heat dissipation air duct is connected to two corrugated air pipes, and the heat dissipation water pipe is connected to two corrugated water pipes.

[0015] Furthermore, the inner surface of the heat dissipation air duct is connected to a separation ring, and the separation ring is connected to the outer surface of the heat dissipation water pipe.

[0016] Furthermore, an exhaust pipe is connected to the upper surface of the heat dissipation shell, and a first exhaust port and a second exhaust port are provided at the bottom end of the exhaust pipe. The position of the first exhaust port corresponds to the side wall of the heat dissipation shell, and the position of the second exhaust port corresponds to the top of the first screw module.

[0017] According to the above technical solution of an automobile parts cutting tool, it will also be provided, including the following steps:

[0018] S1. 3D Positioning Step: The second screw module in the y / z-axis translation assembly drives the slider to achieve y-axis displacement. The third screw module drives the x-axis translation assembly to achieve z-axis elevation. The first screw module in the x-axis translation assembly drives the cutting head to achieve x-axis movement, allowing the cutting head to be accurately positioned in three dimensions to the desired cutting location.

[0019] S2. Cutting operation steps: Start the cutting head to cut the automotive parts, and trigger the cooling system to operate;

[0020] S3. Combined heat dissipation step: Coolant flows from the water pipe into the corrugated water pipe and circulates through the heat dissipation water pipe within the heat dissipation housing, absorbing heat generated by the cutting head. A fan delivers air into the heat dissipation duct through the air pipe and the corrugated air pipe. Guided by a separator ring, the air fully contacts the heat dissipation water pipe, enhancing heat exchange. The hot air is discharged through the first and second exhaust ports of the exhaust pipe, respectively, to clean debris from the first screw module and the heat dissipation housing.

[0021] S4. Movement protection step: During the movement of the cutting head, the accordion shielding sheet is expanded or folded along with the movement of the first screw module and the third screw module, thereby preventing metal debris from entering the transmission mechanism.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] First, the present invention utilizes a three-axis linkage design, combining the Y / Z and X-axis translation assemblies, to enable precise displacement of the cutting head in the x / y / z directions. The second and third screw modules in the Y / Z translation assemblies work together to achieve two-dimensional adjustment within the vertical plane, while the first screw module in the X-axis translation assembly performs horizontal movement. These three elements work together to enable the cutting head to adapt to complex cutting scenarios, including flat surfaces, inclined surfaces, and three-dimensional contours, eliminating the positioning blind spots associated with traditional single-axis adjustment.

[0024] Secondly, the cooling water pipes and cooling air ducts within the heat dissipation housing of the present invention form a dual-circulation gas-liquid cooling system. Coolant circulates through the water pipes and corrugated water pipes, absorbing heat. Simultaneously, a fan delivers air into the cooling air ducts through the air ducts and corrugated air ducts. The turbulent flow created by the separator ring enhances heat exchange, and the hot air is finally discharged through the dual exhaust ports of the exhaust pipe. This overcomes the efficiency bottleneck of traditional single-mode cooling methods and achieves balanced temperature control of the cutting head.

[0025] Third, the present invention's accordion-style shielding panels are fixed to the ends of the screw module via first and second U-shaped connecting pieces. They expand and collapse synchronously with the machine's movement, forming a continuous protective barrier that effectively blocks metal debris, coolant, and other debris generated during the cutting process from entering the screw drive mechanism. Compared to traditional open structures, this significantly reduces the risk of wear on transmission components.

DETAILED DESCRIPTION

[0035] To facilitate understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the content disclosed in the present invention more thorough and comprehensive.

[0036] It should be noted that when an element is referred to as being "fixed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this article are for illustrative purposes only.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly associated with those skilled in the art to which the present invention pertains. The terminology used herein in the specification of the present invention is for the purpose of describing specific embodiments and is not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0038] The embodiment of the present application provides an automobile parts cutting tool. The automobile parts cutting tool schematic diagram is as follows Figure 1-4 As shown. The automotive parts cutting tool includes a cutting table 10, a position adjustment mechanism 20 is connected to the table body of the cutting table 10, and a cutting head 30 is connected to the execution end of the position adjustment mechanism 20;

[0039] The position adjustment mechanism 20 includes a y / z axis translation assembly 21 connected to the cutting table 10, and an x ​​axis translation assembly 22 connected to the execution end of the y / z axis translation assembly 21;

[0040] The x-axis translation assembly 22 includes a first screw module 221 connected to the y / z-axis translation assembly 21 . The execution end of the first screw module 221 is connected to a heat dissipation shell 222 , and the heat dissipation shell 222 is connected to the cutting head 30 .

[0041] It should be noted that in this embodiment, the y / z-axis translation assembly 21 and the x-axis translation assembly 22 on the cutting table 10 form a three-dimensional motion mechanism: the y / z-axis translation assembly, through a combination of a lead screw and a linear module, adjusts the position of the cutting head in the vertical y / z-axis plane; the x-axis translation assembly drives the cutting head in the horizontal x-axis direction via a first lead screw module 221. The three components work together to allow the cutting head to be positioned arbitrarily in three-dimensional space, meeting cutting requirements at different angles and heights. Multi-dimensional processing adaptability is achieved through the collaboration of the y / z-axis translation assembly 21 and the x-axis translation assembly 22, enabling the completion of complex cutting tasks such as planes, inclined planes, and three-dimensional contours. Motion coordination achieves trajectory fitting through three-axis linkage, avoiding the positioning blind spots of traditional single-axis adjustment. Compactness is achieved by integrating the modular y / z-axis translation assembly 21 and the x-axis translation assembly 22 into the cutting table 10, reducing equipment space.

[0042] Optional, please refer to the attached Figure 3 The y / z-axis translation assembly 21 includes a second screw module 211 connected to both sides of the cutting table 10, a slider 212 connected to the execution end of the second screw module 211, and a third screw module 213 connected to the upper surface of the slider 212. The execution end of the third screw module 213 is connected to the first screw module 221.

[0043] In this embodiment, in the y / z-axis translation assembly 21, the second screw module 211 drives the slider 212 to move linearly along the y-axis through the screw nut pair, and the third screw module 213 is connected to the slider 212 through a linear guide rail to drive the x-axis translation assembly 22 to rise and fall in the z-axis direction. When it is necessary to adjust the height or horizontal position of the cutting head, the two groups of modules act separately or synchronously to form a two-dimensional motion in the y / z-axis plane. The vertical adjustment capability is adapted to the cutting requirements of workpieces of different thicknesses by raising and lowering the third screw module 213. The precise transmission of the second screw module 211 ensures that the y-axis positioning error is smaller than that of the traditional gear transmission, thereby improving the horizontal displacement accuracy. The gapless motion characteristics of the third screw module 213 are suitable for high-frequency position adjustment scenarios and improve the dynamic response characteristics.

[0044] Optional, please refer to the attached Figure 2 The outer surfaces of both ends of the first screw module 221 are connected to the first U-shaped connecting piece 224, the outer surfaces of both sides of the third screw module 213 are connected to the second U-shaped connecting piece 225, and an accordion-type shielding piece 226 is connected between the first U-shaped connecting piece 224 and the second U-shaped connecting piece 225 at the same end.

[0045] In this embodiment, accordion-style shielding plates 226 are fixed at both ends of the first and third screw modules 221, 222 via first and second U-shaped connecting plates 224, 225. When the screw modules move, the shielding plates 226 fold or unfold accordingly, forming a continuous protective barrier that prevents metal debris, coolant, and other debris generated during the cutting process from entering the screw transmission mechanism. The dust and debris-proof function of the accordion-style shielding plates 226 prevents debris from getting stuck in the first and third screw modules 221, 222, causing movement jams, reduces wear on the screws and guide rails, extends the life of transmission components, and improves durability. The detachable accordion-style shielding plates 226 facilitate quick cleaning of accumulated debris, enhancing maintenance convenience.

[0046] Optional, please refer to the attached Figure 3 Hollow protrusions 223 are connected to both ends of one side surface of the first screw module 221 , and a corrugated water pipe 2231 is connected between the hollow protrusion 223 and the third screw module 222 .

[0047] In this embodiment, the hollow protrusion 223 is connected to the third screw module 222 via a corrugated water pipe 2231 to form a coolant circulation channel. When the cutting head generates heat during operation, the coolant flows from the water pipe 2233 into the corrugated water pipe 2231, flows through the heat dissipation water pipe 2222 in the heat dissipation shell 222, absorbs heat, and then flows back, using the heat conduction characteristics of the liquid to remove the heat from the cutting head. The flexible structure of the corrugated water pipe 2231 adapts to the displacement changes during the movement of the screw, forming a reliable heat exchange path, avoiding the risk of leakage caused by the movement and pulling of the rigid water pipe, and ensuring the continuity of heat dissipation. The layout of the water pipe 2233 and the corrugated water pipe 2231 does not interfere with the mechanical moving parts, thereby improving the structural compatibility.

[0048] Optional, please refer to the attached Figure 3 and 4 The outer portion of the corrugated water pipe 2231 is provided with a corrugated air pipe 2232 , and the corrugated air pipe 2232 is connected between the hollow protrusion 223 and the third screw module 222 .

[0049] In this embodiment, the corrugated air duct 2232 is mounted on the outside of the corrugated water pipe 2231 and communicates with the hollow protrusion 223 and the heat dissipation duct 2221 of the heat dissipation shell 222, forming an air circulation path. The fan 2235 drives air through the corrugated air duct 2232 and into the heat dissipation shell 222, reducing the temperature of the cutting head through air cooling. At the same time, the surface of the water pipe 2233 and the corrugated water pipe 2231 is cooled to prevent the coolant from overheating. The composite structure formed by the corrugated air duct 2232 and the corrugated water pipe 2231 realizes a gas-liquid dual-circulation heat dissipation mechanism, enhancing heat dissipation efficiency. The corrugated structure allows the air duct 2232 and the water pipe 2231 to bend with mechanical movement without affecting the medium transmission. The air flow can carry away condensed water on the surface of the water pipe 2233 and the corrugated water pipe 2231, protecting the electrical components.

[0050] Optional, please refer to the attached Figure 5 The inside of the hollow protrusion 223 is connected to a water pipe 2233, which is connected to the corrugated water pipe 2231 on the same side. The outside of the water pipe 2233 is connected to an air duct 2234, and one end of the air duct 2234 extending to the outside is connected to a fan 2235, which is connected to the outer surface of the hollow protrusion 223.

[0051] In this embodiment, the water pipe 2233 inside the hollow protrusion 223 is connected to the corrugated water pipe 2231, and the external air duct 2234 is connected to the fan 2235, forming an independent liquid cooling and air cooling cycle. The coolant circulates in the water pipe 2233 and the corrugated water pipe 2231 to absorb the heat of the cutting head. The fan 2235 sends air into the air duct 2234, enters the heat dissipation shell 222 through the corrugated air duct 2232, and exchanges heat with the heat dissipation water pipe 2222 to achieve gas-liquid thermal coupling heat dissipation. The separate design of the liquid cooling and air cooling cycles avoids fluctuations in heat dissipation efficiency caused by gas-liquid mixing. The independent systems of the water pipe 2233, the corrugated water pipe 2231 and the air duct 2234, the corrugated air duct 2232 can work alone or in coordination to adapt to different load conditions. When a single heat dissipation method fails, the other system can maintain the basic heat dissipation function, thereby improving fault redundancy.

[0052] Optional, please refer to the attached Figure 5 and 6 A heat dissipation duct 2221 is provided on the shell of the heat dissipation shell 222. A heat dissipation water pipe 2222 is connected to the interior of the heat dissipation duct 2221. The heat dissipation duct 2221 is connected to two corrugated air pipes 2232. The heat dissipation water pipe 2222 is connected to two corrugated water pipes 2231.

[0053] In this embodiment, the heat dissipation duct 2221 of the heat dissipation housing 222 is connected to the corrugated air duct 2232, and the internal heat dissipation water pipe 2222 is connected to the corrugated water pipe 2231, forming an "air-heat dissipation water pipe 2222-cutting head" heat exchange system. When air flows through the heat dissipation duct 2221, it comes into contact with the surface of the heat dissipation water pipe 2222, absorbing heat transferred from the coolant in the water pipe and then being discharged through the exhaust pipe 2224. At the same time, the coolant absorbs heat from the cutting head and circulates through the corrugated water pipe 2231. The staggered layout of the heat dissipation duct 2221 and the heat dissipation water pipe 2222 expands the heat exchange area. The dual air-liquid heat dissipation method is more effective than a single heat dissipation method. The air flow in the heat dissipation duct 2221 can even out the surface temperature field of the cutting head and improve temperature balance.

[0054] Optionally, referring to the accompanying drawings, the inner surface of the heat dissipation duct 2221 is connected to a separation ring 2223 , and the separation ring 2223 is connected to the outer surface of the heat dissipation water pipe 2222 .

[0055] In this embodiment, a separator ring 2223 within the cooling duct 2221 is fixed to the outer surface of the cooling water pipe 2222, dividing the duct into multiple flow paths and guiding air along specific paths. This increases the contact time between the air and the cooling water pipe 2222 and the degree of turbulence, thereby enhancing heat exchange efficiency. The separator ring 2223 optimizes the flow field within the cooling duct 2221, prevents air short-circuits, and improves heat dissipation uniformity. It also secures the cooling water pipe 2222, preventing vibration and displacement in high-speed airflow. Turbulent flow overcomes the thermal resistance of the boundary layer on the surface of the cooling water pipe 2222, enhancing heat exchange.

[0056] Optional, please refer to the attached Figure 4 and 5 The upper surface of the heat dissipation shell 222 is connected to an exhaust pipe 2224, and the bottom end of the exhaust pipe 2224 is provided with a first exhaust port and a second exhaust port. The position of the first exhaust port corresponds to the side wall of the heat dissipation shell 222, and the position of the second exhaust port corresponds to the top of the first screw module 221.

[0057] In this embodiment, the exhaust pipe 2224 on the heat dissipation housing 222 is provided with a first exhaust port and a second exhaust port: the first exhaust port is aligned with the side wall of the heat dissipation housing 222 to exhaust the high-temperature air after heat exchange with the cutting head; the second exhaust port is aligned with the top of the first screw module 221 to exhaust the heat generated by the screw movement and any debris that may enter. The dual exhaust port design accelerates the renewal of air within the heat dissipation housing 222. The dual exhaust ports specifically exhaust hot air generated by different heat sources, namely the side wall of the heat dissipation housing 222 and the top of the first screw module 221, thereby reducing exhaust back pressure, maintaining the airflow velocity within the air duct, and improving the stability of the flow field. The airflow from the second exhaust port can sweep the surface of the first screw module 221 to prevent debris accumulation, thus providing a protective function.

[0058] Based on the same inventive concept, this embodiment also provides the following steps:

[0059] S1. Three-dimensional positioning step: The second screw module 211 of the y / z-axis translation assembly 21 drives the slider 212 to achieve y-axis displacement. The third screw module 213 drives the x-axis translation assembly 22 to achieve z-axis elevation. The first screw module 221 of the x-axis translation assembly 22 drives the cutting head 30 to achieve x-axis movement, so that the cutting head 30 is accurately positioned in three-dimensional space at the cutting position to be cut.

[0060] S2 cutting operation steps: start the cutting head 30 to cut the automotive parts, while triggering the cooling system to run;

[0061] S3. Composite heat dissipation step: Coolant flows from water pipe 2233 into corrugated water pipe 2231, circulates through heat dissipation pipe 2222 within heat dissipation housing 222, and absorbs heat generated by cutting head 30; fan 2235 delivers air to heat dissipation duct 2221 through air duct 2234 and corrugated air duct 2232. The air, guided by separator ring 2223, fully contacts heat dissipation pipe 2222, enhancing heat exchange; hot air is discharged through the first exhaust port and the second exhaust port of exhaust pipe 2224, respectively, to clean debris on the first screw module 221 and heat dissipation housing 222;

[0062] S4. Movement protection step: During the movement of the cutting head 30 , the accordion shielding piece 226 is unfolded or folded along with the movement of the first screw module 221 and the third screw module 222 , thereby preventing metal debris from entering the transmission mechanism.

[0063] The specific operation mode of the present invention is as follows:

[0064] A three-dimensional motion system is formed by the y / z-axis translation component 21 and the x-axis translation component 22: the second screw module 211 in the y / z-axis translation component 21 drives the slider 212 to achieve y-axis displacement, the third screw module 213 drives the x-axis translation component 22 to complete z-axis lifting, and the first screw module 221 of the x-axis translation component 22 drives the heat dissipation shell 222 and the cutting head 30 to achieve x-axis movement. The three axes work together to accurately position the cutting head 30 in three-dimensional space.

[0065] During cutting, heat generated by the cutting head 30 is exchanged with the cooling air duct 2221 via the cooling water pipe 2222 within the heat sink housing 222. Coolant circulates through the cooling water pipe 2233 and the corrugated water pipe 2231, absorbing heat. A fan 2235 then delivers air to the cooling air duct 2221 via the air duct 2234 and the corrugated air duct 2232. The dual gas-liquid cooling medium, guided by the separator ring 2223, enhances heat exchange. Finally, the hot air is discharged through the dual exhaust ports of the exhaust pipe 2224. Regarding motion protection, the accordion-style shielding plate 226 expands and collapses with the movement of the screw module, preventing debris from entering the transmission mechanism. The flexible structure of the hollow protrusion 223 and the corrugated pipe adapts to mechanical movement and displacement, ensuring the coordinated operation of the cooling and motion systems.

[0066] The above description of the present invention is exemplified in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as such non-substantial improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
