Technical Field
[0001] This utility model relates to the field of machine tool technology, and more specifically, to a chip-removing device and a machine tool. Background Technology
[0002] With the rapid development of modern manufacturing and the continuous growth of market application demands, CNC machine tools, as core processing equipment, have been widely used in precision manufacturing fields such as automobile manufacturing, mold processing, aerospace, and military industries. In CNC cutting processes, conventional tools often struggle to meet the machining requirements of complex curved surfaces or irregularly shaped parts. Therefore, angle head devices are commonly used to change the direction of the tool axis to achieve the machining requirements. In existing technologies, angle head tools are typically fixed to the end of the machine tool spindle via a positioning block assembly. This positioning block achieves axial positioning through a screw connection and restricts its circumferential rotation through a stop structure, thereby ensuring stable tool positioning during machining.
[0003] However, in actual machining processes, the machine tool spindle generates a large amount of metal chips during high-speed rotation and cutting. These chips, under the action of centrifugal force, splash radially, and with the flushing of cutting fluid, aluminum chips mixed with cutting fluid easily adhere to the positioning surface of the positioning block. Especially in scenarios where coolant is used for machining, aluminum chips easily mix with the coolant to form a sticky substance. Chips remaining on the positioning surface of the positioning block will damage the positioning accuracy and affect the machining quality of the tool. Utility Model Content

[0027] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0028] Please refer to Figures 1 to 8 The first embodiment of this utility model provides a chip removal device for a machine tool, including a liquid pipeline 100 and a positioning block 200. The positioning block 200 includes: a positioning part 210, on which a positioning surface 211 for mounting an angle head 500 is provided; a chip removal channel 220, which is opened on the positioning block 200; the chip removal channel 220 has a liquid inlet 223 and a liquid outlet 224, the liquid inlet 223 is connected to the water outlet of the liquid pipeline 100, and the liquid outlet 224 is arranged facing the positioning surface 211.
[0029] By applying the technical solution of this embodiment, the fluid passage 100 in the machine tool chip removal device is connected to the chip removal channel 220 on the positioning block 200, achieving precise chip removal and cleaning of the positioning surface 211. Specifically, the outlet of the fluid passage 100 is connected to the inlet 223 of the chip removal channel 220, allowing the high-pressure chip removal fluid to be directionally delivered to the outlet 224 near the positioning surface 211. When the chip removal fluid is sprayed onto the positioning surface 211 through the outlet 224, it effectively removes the residual aluminum chips and coolant mixture, ensuring the cleanliness of the positioning surface 211 and thus improving the installation accuracy between the angle head and the positioning block 200. In addition, this technical solution also solves the problem of manually cleaning aluminum chips on the positioning surface 211 in the prior art, avoiding the decrease in production efficiency caused by machine downtime for cleaning. By continuously cleaning the positioning surface 211 with chip removal, this invention not only eliminates the impact of aluminum chips on positioning accuracy but also significantly reduces manual intervention, improving the continuity and automation level of the machine tool processing, thereby enhancing the machining quality and production efficiency of the machine tool. This simple and easy-to-implement chip removal device provides an effective solution for CNC machine tool processing, and is particularly suitable for high-precision, high-efficiency mass production environments of metal parts.
[0030] Furthermore, in this embodiment, there are multiple positioning surfaces 211 and multiple chip flushing channels 220. The multiple chip flushing channels 220 are arranged in a one-to-one correspondence with the multiple positioning surfaces 211, and the liquid outlet 224 of each chip flushing channel 220 is arranged facing the corresponding positioning surface 211.
[0031] In this embodiment, the positioning block 200 has multiple positioning surfaces 211 and chip flushing channels 220, with each chip flushing channel 220 corresponding one-to-one with a positioning surface 211, ensuring that each positioning surface 211 can be precisely cleaned. This design utilizes multiple liquid outlets 224 to directionally flush the positioning surfaces 211, effectively removing aluminum chip residue and avoiding precision loss and tool jamming caused by chip accumulation. By precisely orienting the liquid outlets 224 of the multiple chip flushing channels 220 towards their corresponding positioning surfaces 211, a high-precision connection between the positioning block 200 and the angle head 500 can be maintained even in complex machining environments, improving machining quality and efficiency. Furthermore, this one-to-one flushing configuration ensures maximum liquid utilization during the chip flushing process, reducing resource waste, simplifying the cleaning process of the positioning block 200, eliminating the need for frequent manual intervention, reducing operating costs, and improving the automation level and economic benefits of the production line.
[0032] In summary, the pairing design of multiple positioning surfaces 211 and chip flushing channel 220 in this embodiment not only achieves comprehensive cleaning of the positioning surfaces 211 and improves positioning accuracy, but also enhances chip flushing efficiency through precise fluid guidance. This makes a significant contribution to improving the machining quality and production efficiency of CNC machine tools, while also reflecting the rational use of environmental resources.
[0033] Furthermore, in this embodiment, as Figure 2 As shown, the positioning surface 211 includes a first positioning surface 2111 and a second positioning surface 2112; the chip flushing channel 220 includes a first chip flushing channel 221 and a second chip flushing channel 222; the liquid outlet of the first chip flushing channel 221 is set towards the second positioning surface 2112, and the liquid outlet of the second chip flushing channel 222 is set towards the first positioning surface 2111; wherein, the extension direction of the first chip flushing channel 221 and the extension direction of the second chip flushing channel 222 are set at a preset angle and intersect, and the intersection of the first chip flushing channel 221 and the second chip flushing channel 222 forms a junction, which is connected to the water outlet of the liquid pipeline 100, and both the first chip flushing channel 221 and the second chip flushing channel 222 are fed with liquid through the junction.
[0034] In this embodiment, the positioning surface 211 is refined into a first positioning surface 2111 and a second positioning surface 2112; the chip flushing channel 220 includes a first chip flushing channel 221 and a second chip flushing channel 222. The liquid outlets of the first chip flushing channel 221 and the second chip flushing channel 222 are respectively aligned with the second positioning surface 2112 and the first positioning surface 2111, ensuring that both positioning surfaces can be effectively flushed. The extension directions of these two channels are designed to intersect at a preset angle, forming a junction, which is directly connected to the water outlet of the liquid pipeline 100, thus allowing the chip flushing fluid to enter both channels simultaneously. When the chip flushing fluid enters the positioning block 200 through the junction, it flows in the first chip flushing channel 221 and the second chip flushing channel 222. Thanks to the special tilt angle and junction structure of the channels, the flow of liquid in the channels generates a two-way jetting effect, effectively removing residual chips on the first positioning surface 2111 and the second positioning surface 2112, ensuring positioning accuracy and processing efficiency. This structure not only enhances chip removal capability but also simplifies piping layout, reduces system complexity, and improves maintenance convenience. This multi-channel directional chip removal design ensures the angle head positioning block remains clean during machine tool processing, avoiding accuracy loss due to residual chips and the frequent need for manual cleaning, thereby improving the continuity and automation level of the entire machining process. In other embodiments not shown in the figures, the channel angles and intersection positions can be adjusted to adapt to different machining conditions and machine tool configurations, further enhancing the application range and flexibility of the chip removal device.
[0035] Furthermore, in this embodiment, as Figure 4 He Ru Figure 5 As shown, the positioning block 200 includes a positioning opening groove 212. The two oppositely arranged side walls of the positioning opening groove 212 respectively form a first positioning surface 2111 and a second positioning surface 2112. The positioning opening groove 212 also has a bottom wall located between the two side walls. The liquid outlet of the first chip flushing channel 221 and the liquid outlet of the second chip flushing channel 222 are both opened on the bottom wall.
[0036] In this embodiment, the positioning block 200 integrates a positioning opening groove 212. This groove design includes two opposing sidewalls forming the first positioning surface 2111 and the second positioning surface 2112, and a bottom wall located between them. Notably, the outlets of the first chip flushing channel 221 and the second chip flushing channel 222 are both located on the bottom wall. This arrangement ensures that the flushing fluid can directly act on the core area of the positioning block 200, i.e., the bottom of the positioning opening groove 212, ensuring effective removal of the metal chips and coolant mixture. This design not only simplifies the flushing fluid guiding structure but also enhances the cleaning effect on the positioning surface 211, avoiding the problems of decreased machining accuracy and increased equipment maintenance frequency caused by chip residue, thereby improving machine tool efficiency and the quality stability of machined parts. In addition, this arrangement also promotes the uniform distribution of flushing fluid, helping to eliminate local residues, and significantly enhancing the reliability of the positioning block 200 in use. In an alternative embodiment, the position of the outlet can be adjusted according to actual working conditions to adapt to diverse processing needs and further optimize the flushing effect. This design flexibility provides room for subsequent process improvements and equipment upgrades, enhancing the applicability and performance of the positioning block 200 in different application scenarios.
[0037] Furthermore, in this embodiment, as Figure 3 As shown, there are at least two chip flushing channels 220, and the at least two chip flushing channels 220 are arranged to intersect each other; the positioning block 200 also includes a water inlet channel 230, which is opened on the positioning block 200. The intersection of the at least two chip flushing channels 220 is connected to one end of the water inlet channel 230, and the other end of the water inlet channel 230 is located on the outer surface of the positioning block 200 and is connected to the liquid inlet pipe 100.
[0038] In this embodiment, the positioning block 200 integrates multiple chip flushing channels 220. These channels intersect and connect to one end of the water inlet channel 230, while the other end of the water inlet channel 230 is exposed on the outer surface of the positioning block 200 to establish a connection with the external liquid supply line 100. This design allows the chip flushing fluid to be distributed to each chip flushing channel 220 through the water inlet channel 230 after entering the positioning block 200, forming a multi-point directional flushing mode, which enhances the ability to remove residual aluminum chips from the positioning surface 211. The intersecting chip flushing channels 220 not only expand the chip flushing range but also cooperate with each other to eliminate the flushing dead zones that may exist in a single channel, ensuring comprehensive cleaning of the positioning surface. The connection structure between the water inlet channel 230 and the chip flushing channels 220, as well as the interface design of the outer surface of the positioning block 200, together constitute a highly efficient chip flushing system. This system effectively removes aluminum chips between the positioning block 200 and the angle head 500 using high-pressure chip-removing fluid, preventing installation jamming caused by aluminum chips, improving assembly accuracy, and reducing the frequency of manual intervention. This, in turn, enhances the continuity and production efficiency of the entire machine tool processing process. Furthermore, the multi-channel design allows for adjustment of fluid flow and pressure according to actual working conditions, meeting chip-removing requirements under different processing conditions, demonstrating high adaptability and practicality.
[0039] Furthermore, in this embodiment, the liquid passage 100 includes: a first connector 110, one end of which is connected to the other end of the water inlet channel 230; a pipe fitting 120, one end of which is connected to the other end of the first connector 110; and a second connector 130, one end of which is connected to the other end of the pipe fitting 120, and the other end of which is connected to the water outlet of the machine tool spindle 300.
[0040] In this embodiment, the fluid conduit 100 consists of a first connector 110, a fitting 120, and a second connector 130. The first connector 110 is tightly connected to one end of the water inlet channel 230 inside the positioning block, ensuring leak-free transmission of the high-pressure chip flushing fluid. The fitting 120 acts as a connecting bridge, with one end connected to the first connector 110 and the other end connected to the second connector 130, playing a crucial role in extending the fluid path. The second connector 130 is connected to the water outlet of the machine tool spindle 300, achieving effective docking of the chip flushing system between the water outlet of the machine tool spindle 300 and the positioning block 200. The design of the entire fluid conduit 100 not only ensures high-pressure fluid transmission from the water outlet of the machine tool spindle 300 to the positioning block 200, but also ensures directional flow of the chip flushing fluid and efficient cleaning of the positioning surface 211 through precise matching between the components. This technical solution overcomes the problem of chip adhesion in the coolant environment of traditional positioning blocks, improves the accuracy and convenience of tool changing, and thus enhances the continuity and production efficiency of machine tool processing. In other embodiments, the components of the fluid conduit 100 can use different types of joints and pipes to adapt to more diverse processing environments and requirements, demonstrating the flexibility and scalability of the device.
[0041] Furthermore, in this embodiment, as Figure 7 As shown, the other end of the second connector 130 is connected to the water outlet of the machine tool spindle 300 via the spindle adapter block 400; and / or, at least one of the first connector 110 and the second connector 130 is an L-shaped structure, the L-shaped structure including a first connecting part and a second connecting part connected at a preset angle.
[0042] Preferably, such as Figure 6 As shown, the inner wall of the water inlet channel 230 is provided with an internal thread, and the first connecting part of the first connector 110 is provided with an external thread. The first connecting part of the first connector 110 is threadedly connected to the water inlet channel 230, which improves the connection efficiency between the liquid passage 100 and the positioning block 200.
[0043] Preferably, such as Figure 8 As shown, the upper part of the spindle adapter block 400 is provided with an external thread, which is threaded to the machine tool spindle 300, thereby improving the connection efficiency.
[0044] In this embodiment, the other end of the second connector 130 is connected to the water outlet of the machine tool spindle 300 via the spindle adapter block 400. This configuration ensures a stable and efficient transmission path for the flushing fluid. Simultaneously, at least one of the first connector 110 and the second connector 130 adopts an L-shaped structure, consisting of a first connecting part and a second connecting part. The preset included angle design optimizes the fluid flow direction, allowing the flushing fluid to be more precisely guided to the oblique through-hole of the positioning block, effectively enhancing the flushing effect. This improvement not only solves the problem of aluminum chip residue on the positioning surface of the positioning block and improves the assembly and disassembly efficiency of the angle head and the positioning block, but also ensures positioning accuracy during processing and reduces the occurrence of tool clamping abnormalities. The unique design of the L-shaped connector and the use of the spindle adapter block 400 create a directional flushing path from the water outlet of the machine tool spindle 300 directly to the positioning surface 211 of the positioning block 200, achieving continuous and high-speed cleaning of the positioning surface, thereby improving the overall operating efficiency and product quality of the machine tool; the design of the spindle adapter block 400 solves the technical problem that the interface of the second connector 130 cannot match the water outlet of the machine tool spindle 300.
[0045] Specifically, the first connecting part of the L-shaped first connector 110 is threaded into the water inlet channel on the positioning block 200, ensuring sealed liquid delivery. The second connecting part of the first connector 110 is connected to the pipe fitting 120 via a plug-in connection, quickly and conveniently establishing a liquid transmission link and reducing the risk of leakage caused by improper pipe connections. The spindle adapter block 400, as a key component connecting the water outlet of the machine tool spindle 300 and the L-shaped second connector 130, solves the problem of mismatched thread specifications between the two, ensuring an uninterrupted supply of flushing fluid and achieving continuous and efficient flushing of the positioning surface 211. Optionally, the first connecting part of the second connector 130 is threaded into the spindle adapter block 400, and the second connecting part of the second connector 130 is plugged into the pipe fitting 120. This combination of structural design and fluid dynamics principles allows the positioning block 200 to automatically remove aluminum chips without manual intervention, avoiding positioning errors caused by residual substances and significantly improving the production efficiency and machining accuracy of the CNC machine tool. Furthermore, this embodiment demonstrates good adaptability and scalability, making it easy to promote and apply on different types of machine tools.
[0046] Furthermore, in this embodiment, along the extension direction from the liquid inlet 223 to the liquid outlet 224 of the chip flushing channel 220, the flow area of the chip flushing channel 220 gradually decreases.
[0047] In this embodiment, the flow area of the chip flushing channel 220 gradually decreases along its extension direction from the inlet 223 to the outlet 224. This design, based on fluid dynamics principles, increases the flow velocity and pressure of the flushing fluid within the channel by reducing the cross-sectional area at the end of the channel, thereby enhancing the ability to remove residual metal chips from the positioning surface 211. When the high-pressure flushing fluid enters from the inlet 223, passes through the variable-diameter structure of the channel, and reaches the outlet 224, its flushing force on the positioning surface is significantly enhanced, effectively removing aluminum chips and other impurities from the positioning surface 211. This avoids tool positioning abnormalities and accuracy degradation caused by chip residue, while also reducing manual cleaning time and significantly improving processing efficiency and positioning accuracy stability. Furthermore, the gradual reduction in flow area helps to form a concentrated flow stream, allowing the flushing fluid to be sprayed more precisely onto the positioning surface, further improving the cleaning effect and ensuring smooth installation and reliable connection between the angle head 500 and the positioning block 200.
[0048] Furthermore, in this embodiment, the chip flushing channel 220 has a first end and a second end along its axial direction. The first end forms the liquid outlet 224 of the chip flushing channel 220, and the liquid inlet 223 of the chip flushing channel 220 is opened on the side wall of the chip flushing channel 220. The second end of the chip flushing channel 220 is an open end. The machine tool chip flushing device also includes a plug 240, which is sealed at the open end. Specifically, the plug 240 is a set screw, and the second end of the chip flushing channel 220 is provided with an internal thread, and the set screw is threadedly connected to the internal thread.
[0049] In this embodiment, the chip flushing channel 220 has a first end and a second end along its axial direction. The first end forms the liquid outlet 224 of the chip flushing channel 220, while the liquid inlet 223 is opened on the side wall of the chip flushing channel 220. This allows liquid to enter from the side and flush the positioning surface 211 through the liquid outlet 224 at the front end. The second end of the chip flushing channel 220 is an open end. At this time, the machine tool chip flushing device also includes a plug 240, which seals the opening at the second end to isolate it from the external environment and prevent liquid leakage during operation. This design ensures that the chip flushing liquid flows out only from the preset liquid outlet 224, cleaning the positioning surface 211 in a directional manner while avoiding unnecessary waste of resources. Through this structure, the accuracy and efficiency of flushing can be effectively improved, thereby ensuring the accuracy of tool positioning, reducing the failure rate in the production process, and improving the overall machining quality and machine tool operation stability. In other embodiments not shown, the design of the plug 240 can be more diverse to adapt to different working environments and operational requirements, ensuring the reliability and effectiveness of the chip removal device under various conditions.
[0050] Furthermore, the upper part of the positioning block 200 is provided with a mounting hole 250, and the positioning block 200 is connected to the machine tool spindle 300 through the mounting hole 250.
[0051] This invention effectively solves the problem of aluminum chip residue at the positioning surface 211 of the positioning block 200 caused by the mixing of coolant and chips by adding a chip flushing channel 220, a water inlet channel 230, and a liquid flow pipe 100 to the positioning block. This avoids the impact of aluminum chips on tool positioning deviation and significantly improves the machining accuracy and efficiency of the machine tool. Furthermore, by improving the design of the internal flow channel cross-sectional dimensions, the flow rate is increased, achieving high-speed and efficient flushing, reducing the frequency of manual cleaning, and lowering production costs. The introduction of the L-shaped first connector 110 and second connector 130 not only simplifies the pipeline connection process but also ensures the stable delivery of high-pressure flushing fluid, further improving positioning accuracy and reducing downtime caused by tool jamming. Overall, the chip flushing device of this invention has the advantages of high automation, good cleaning effect, and simple maintenance, and plays an important role in improving the machining quality and production efficiency of CNC machine tools.
[0052] The second embodiment of this utility model provides a machine tool, which includes the chip-removing device described in any of the above-mentioned claims.
[0053] This machine tool integrates a chip-removing device into its structure, enabling real-time and effective removal of aluminum chips and coolant residue from the positioning surface 211 during machining. This avoids tool positioning errors and clamping abnormalities caused by chip residue, significantly improving machining accuracy. Furthermore, the automated chip-removing process reduces the need for manual intervention, shortens non-machining time, and enhances the overall machining efficiency of the machine tool. This design not only ensures the cleanliness of the positioning surface 211 but also optimizes the assembly process between the positioning unit 210 and the angle head 500, making tool changes smoother and further enhancing the stability and reliability of the machine tool. It is particularly suitable for application in high-precision, high-efficiency production environments and has a positive significance for promoting technological progress in the field of CNC machine tool machining.
[0054] The working process of the machine tool chip flushing device is as follows: First, the high-pressure chip flushing fluid enters the first connector 110 through the outlet of the machine tool spindle 300, via the second connector 130 and the pipe fitting 120, and then flows into the water inlet channel 230 of the positioning block 200. The water inlet channel 230 introduces the liquid into at least two intersecting chip flushing channels 220, the flow area of which gradually decreases along the liquid flow direction to increase the liquid flow velocity and pressure. The outlets 224 of the chip flushing channels 220 are respectively aligned with the first positioning surface 2111 and the second positioning surface 2112 of the positioning opening slot 212. When the chip flushing fluid is sprayed out from the outlet 224, the high-speed liquid flow impacts the aluminum chips and coolant mixture on the positioning surface 211, cleaning it.
[0055] To ensure the orientation of the chip flushing fluid and prevent leakage, the second ends of the first chip flushing channel 221 and the second chip flushing channel 222 are sealed with set screws. This process is continuous, even during the assembly or disassembly of the angle head 500 and the positioning block 200, thereby ensuring that the positioning surface 211 is always clean, avoiding the loss of positioning accuracy caused by aluminum chips, and improving the machining quality and production efficiency of the machine tool. After the chip flushing operation is completed, the mixture of washed-off chips and coolant flows with the liquid to the chip removal system, completing the entire chip flushing and cleaning cycle.
[0056] Furthermore, the use of the spindle adapter block 400 solves the problem of mismatched thread specifications between the water outlet of the machine tool spindle 300 and the second connector 130, ensuring stable transmission of the flushing fluid. The entire system design takes into account the principles of fluid mechanics. By optimizing the channel layout and structure, it achieves precise and efficient flushing of the positioning surface 211, significantly improving the cleanliness of the positioning block 200 during use and the continuity of the machine tool machining process. It reduces clamping abnormalities caused by chip residue, lowers the frequency of manual cleaning, and thus improves production efficiency and machining accuracy.
