Description

Technical Field

[0001] This invention relates to the field of cutting equipment technology, and more specifically, to a tool cup assembly. Background Technology

[0002] Currently, in the field of CNC machine tool technology, dust and iron filings are generated during the cutting process, and these dust and iron filings accumulate in various parts of the machining equipment. For cutting machining equipment, if the tool cup is covered with dust and iron filings, it can cause the tool cup beads and springs to jam, leading to problems such as tool jamming and tool drop during tool changes. In addition, when performing tool changes, dust inside the tool cup will also adhere to the tool holder, which not only affects the normal operation of the robot, but may even cause problems such as excessive vibration and runout of the spindle when the contaminated tool holder is transferred to the spindle. These effects can easily lead to poor workpiece machining accuracy and even damage to the machine tool.

[0003] In existing technologies, to address the aforementioned problems, a spraying method is typically used to clean only the inner hole of the blade cup. However, this cleaning method is ineffective and fails to meet the cleaning objectives. Summary of the Invention

[0004] The main objective of this invention is to provide a blade cup assembly to solve the problem of poor cleaning effect of blade cups in the prior art.

[0005] To achieve the above objectives, the present invention provides a blade cup assembly, comprising: a blade cup having a mounting opening, an inner hole, and a first channel; an end cap disposed at the mounting opening, the end cap having a mounting hole, the mounting hole or the first channel communicating with the environment in which the blade cup assembly is located; the two ends of the first channel communicating with the mounting hole and the inner hole respectively; a retaining bead movably disposed within the mounting hole; and an elastic structure disposed within the mounting hole, the elastic structure being used to apply an elastic force to the retaining bead to move toward the central axis of the blade cup, at least partially avoiding the connection between the mounting hole and the first channel; wherein, there is one first channel; or, there are multiple first channels, the multiple first channels being spaced apart around the central axis of the blade cup.

[0006] Furthermore, the extension direction of the first channel is set parallel to the central axis of the blade cup.

[0007] Furthermore, the blade cup also has a second channel, through which the first channel is connected to the environment where the blade cup assembly is located, and the second channel is connected to the middle of the first channel.

[0008] Furthermore, there are multiple first channels, with at least two adjacent first channels connected by a second channel, and the second channel is connected to the environment where the blade cup assembly is located; wherein, the extension direction of the second channel is set at a preset angle to the extension direction of the first channel.

[0009] Furthermore, the end cap also has a first connecting hole and a dust outlet spaced apart. The mounting hole is connected to the first channel through the first connecting hole, and the dust outlet is connected to the mounting port.

[0010] Furthermore, along the extension direction of the mounting hole, the first connecting hole and the dust outlet are staggered.

[0011] Furthermore, the blade cup includes: a blade cup body having an installation port and an inner hole; a pipe disposed in the inner hole and connected to the blade cup body, the inner cavity of the pipe forming a first channel, the first end of the pipe penetrating the wall of the installation port, and the second end of the pipe extending into the tapered section of the inner hole.

[0012] Furthermore, the end cap has a second connecting hole and an air inlet spaced apart. The mounting hole is connected to the first channel through the second connecting hole, and the mounting hole is connected to the environment where the blade cup assembly is located through the air inlet. The air inlet and the second connecting hole are located on both sides of the elastic structure, respectively.

[0013] Furthermore, along the extension direction of the mounting hole, the air inlet and the second connecting hole are staggered.

[0014] Furthermore, the extension direction of the air inlet is parallel to the central axis of the blade cup; or, the extension direction of the air inlet is consistent with the extension direction of the mounting hole.

[0015] Furthermore, the elastic structure is a spring, and the retaining bead includes: a sphere having a through hole; a cylinder disposed on the sphere, the inner diameter of the cylinder being the same as the inner diameter of the through hole, and the cylinder and the sphere being coaxially disposed; wherein at least a portion of the cylinder extends into the spring.

[0016] Furthermore, the cross-section of the first channel is circular, elliptical, oblong, or polygonal.

[0017] According to the technical solution of this invention, the cutter cup of the cutter cup assembly has a first channel, and the end cap has a mounting hole, which communicates with the environment in which the cutter cup assembly is located. The two ends of the first channel communicate with the mounting hole and the inner hole, respectively. An elastic structure is disposed within the mounting hole, and the elastic structure applies an elastic force to the retaining bead, causing it to move towards the central axis of the cutter cup. At least a portion of the elastic structure avoids the connection between the mounting hole and the first channel. Thus, when the cutter cup needs cleaning, a cleaning medium or gas is introduced into the mounting hole. This cleaning medium or gas not only cleans the elastic structure and retaining bead located within the mounting hole but also enters the first channel to clean the inner hole, thereby solving the problem of poor cleaning effect on the cutter cup in the prior art, improving the overall cleanliness of the cutter cup assembly, and preventing contamination of the cutter bar or even the machine tool.

[0037] To address the problem of poor cleaning performance of blade cups in existing technologies, this application provides a blade cup assembly.

[0038] Example 1

[0039] like Figures 1 to 4 As shown, the blade cup assembly includes a blade cup 10, an end cap 20, a retaining bead 30, and an elastic structure 40. The blade cup 10 has a mounting opening, an inner hole 11, and a first channel 12. The end cap 20 is disposed at the mounting opening and has a mounting hole 21, which communicates with the environment in which the blade cup assembly is located. The two ends of the first channel 12 communicate with the mounting hole 21 and the inner hole 11, respectively. The retaining bead 30 is movably disposed within the mounting hole 21. The elastic structure 40 is disposed within the mounting hole 21 and applies an elastic force to the retaining bead 30, causing it to move towards the central axis of the blade cup 10. At least a portion of the elastic structure 40 avoids the connection between the mounting hole 21 and the first channel 12. The first channel 12 may be one; or multiple first channels 12 may be spaced apart around the central axis of the blade cup 10.

[0040] Applying the technical solution of this embodiment, the cutter cup 10 of the cutter cup assembly has a first channel 12, and the end cap 20 has a mounting hole 21, which communicates with the environment where the cutter cup assembly is located. The two ends of the first channel 12 communicate with the mounting hole 21 and the inner hole 11, respectively. An elastic structure 40 is disposed within the mounting hole 21. The elastic structure 40 is used to apply an elastic force to the retaining bead 30, causing it to move towards the central axis of the cutter cup 10. At least a portion of the elastic structure 40 avoids the connection between the mounting hole 21 and the first channel 12. Thus, when the cutter cup needs cleaning, a cleaning medium or gas is introduced into the mounting hole 21. This cleaning medium or gas can not only clean the elastic structure 40 and the retaining bead 30 located within the mounting hole 21, but also enter the first channel 12 to clean the inner hole 11, thereby solving the problem of poor cleaning effect on the cutter cup in the prior art, improving the overall cleanliness of the cutter cup assembly, and preventing contamination of the cutter bar or even the machine tool.

[0041] In this embodiment, the aforementioned arrangement of the first channel 12 can, on the one hand, prevent dust and iron filings accumulated in the tool cup 10 from causing the jamming ball 30 and elastic structure 40 to become stuck, resulting in problems such as tool jamming and tool drop. On the other hand, it can, to a certain extent, prevent dust from adhering to the tool holder during subsequent tool changing operations, which could cause problems such as the tool changing arm spring and thumb getting stuck, and the impact of unclean tool holders when swapping to the spindle, such as large vibration and large runout during spindle rotation. Thus, the aforementioned arrangement of the tool cup assembly can improve the reliability of the CNC machine tool tool cup and robot mechanism, and effectively maintain machining quality to obtain good machining accuracy.

[0042] In this embodiment, there are four first channels 12, which are arranged at intervals around the central axis of the blade cup 10, and the four first channels 12 are located at the four corners of the blade cup 10.

[0043] It should be noted that the number of first channels 12 is not limited to this and can be adjusted according to working conditions and usage requirements. Optionally, the first channels 12 can be two, three, five, or more.

[0044] In this embodiment, the extending direction of the first channel 12 is parallel to the central axis of the blade cup 10. This arrangement reduces the length of the first channel 12 while ensuring gas delivery, thus ensuring gas can enter the inner hole 11 to clean dust and improving the gas cleaning effect.

[0045] like Figure 2As shown, the cutter cup 10 also has a second channel 13. The first channel 12 is connected to the environment where the cutter cup assembly is located through the second channel 13, and the second channel 13 is connected to the middle of the first channel 12. In this way, the gas in the environment where the cutter cup assembly is located can enter the middle of the first channel 12 through the second channel 13 and then split into two paths. One path acts on the tapered hole section at the bottom of the cutter cup 10 to clean the dust and iron filings on the wall of the tapered hole section and the dust and iron filings on the cutter bar. The other path is mainly used to clean the dust and iron filings that enter the mounting hole 21. In this way, the dust and iron filings mentioned above are finally cleaned up by the action of the first channel 12, thereby avoiding problems such as tool jamming and tool drop, and thus improving the reliability of the machine tool.

[0046] Optionally, there are multiple first channels 12, with at least two adjacent first channels 12 connected by a second channel 13, which is connected to the environment of the cutter cup assembly. The extension direction of the second channel 13 forms a predetermined angle with the extension direction of the first channel 12. This arrangement reduces the number of second channels 13 while ensuring that gas can enter all first channels 12. This reduces the processing cost of the cutter cup 10 and the processing difficulty for workers, while also reducing the amount of dust entering the cutter cup 10 through the second channels 13.

[0047] In this embodiment, there are two second channels 13, and each second channel 13 is connected to two adjacent first channels 12, so that the structure of the cutter cup 10 is simpler, easier to process and implement, and the processing cost of the cutter cup assembly is reduced.

[0048] It should be noted that the number of second channels 13 is not limited to this and can be adjusted according to working conditions and usage requirements. Optionally, there may be one, three, four, or more second channels 13.

[0049] like Figure 4 As shown, the end cap 20 also has a first connecting hole 22 and a dust outlet 23 spaced apart. The mounting hole 21 is connected to the first channel 12 through the first connecting hole 22, and the dust outlet 23 is connected to the mounting port. This arrangement ensures that the mounting hole 21 can communicate with the first channel 12, allowing gas to be introduced into the mounting hole 21 through the first channel 12 to clean dust and iron filings. Simultaneously, the gas, after cleaning the dust and iron filings, can be discharged through the dust outlet 23, enabling gas flow within the end cap 20 for rapid cleaning of dust and iron filings within the mounting hole 21.

[0050] In this embodiment, the first connecting hole 22 and the dust outlet 23 are staggered along the extending direction of the mounting hole 21. This arrangement increases the path of gas within the mounting hole 21, ensuring that the gas entering the mounting hole 21 can effectively clean away dust and iron filings. Simultaneously, this arrangement improves the structural strength of the end cap 20 and extends the service life of the blade cup assembly.

[0051] like Figure 3 As shown, the cutter cup 10 includes a cutter cup body and a pipe. The cutter cup body has a mounting opening and an inner hole 11. The pipe is disposed within the inner hole 11 and connected to the cutter cup body. The inner cavity of the pipe forms a first channel 12. The first end of the pipe penetrates the wall of the mounting hole 21, and the second end of the pipe extends into the tapered section of the inner hole 11. This arrangement makes the formation of the first channel 12 easier and simpler, reducing the machining difficulty of the first channel 12.

[0052] Optionally, the cross-section of the first channel 12 can be circular, elliptical, oblong, or polygonal. This arrangement allows for greater diversity in the cross-sectional shape of the first channel 12, catering to different usage requirements and working conditions, and also enhancing the processing flexibility for operators.

[0053] In this embodiment, the cross-section of the first channel 12 is circular, so that the structure of the first channel 12 is simpler, easier to process and implement, and the processing cost of the blade cup assembly is reduced.

[0054] In this embodiment, the first connecting hole 22 is a round hole, and the dust outlet 23 is a round hole.

[0055] Example 2

[0056] The difference between the blade cup assembly in Embodiment 2 and Embodiment 1 is that the structure of each channel is different.

[0057] like Figures 5 to 9As shown, the end cap 20 has a second connecting hole 24 and an air inlet 25 spaced apart. The mounting hole 21 is connected to the first channel 12 through the second connecting hole 24, and the mounting hole 21 is connected to the environment where the blade cup assembly is located through the air inlet 25. The air inlet 25 and the second connecting hole 24 are located on both sides of the elastic structure 40, respectively. In this way, the above arrangement ensures that the mounting hole 21 can be connected to the first channel 12 so that gas can be introduced into the mounting hole 21 through the first channel 12 to clean dust and iron filings. At the same time, the gas in the environment where the blade cup assembly is located enters the mounting hole 21 through the air inlet 25 and splits into two paths. One path continues to flow in the mounting hole 21 to clean the dust and iron filings that have entered the mounting hole 21, and the other path enters the tapered section of the inner hole 11 through the first channel 12 to clean the dust and iron filings on the wall of the tapered section and the blade handle. In this way, the dust and iron filings mentioned above are finally cleaned up by the air inlet 25 and the first channel 12, thereby avoiding problems such as tool jamming and tool dropping, and thus improving the reliability of the machine tool.

[0058] Specifically, the gas in the environment where the blade cup assembly is located first enters the mounting hole 21 through the air inlet 25. Part of the gas cleans the dust and iron filings in the mounting hole 21, while the other part of the gas enters the first channel 12 through the second connecting hole 24 until it enters the tapered section of the inner hole 11 to clean the dust and iron filings on the tapered hole wall and the blade holder.

[0059] In this embodiment, the air inlet 25 and the second connecting hole 24 are staggered along the extending direction of the mounting hole 21. This arrangement increases the path of gas within the mounting hole 21, ensuring that the gas entering the mounting hole 21 can effectively clean dust and iron filings. Simultaneously, this arrangement improves the structural strength of the end cap 20 and extends the service life of the blade cup assembly.

[0060] Optionally, the extension direction of the air inlet 25 is parallel to the central axis of the cutter cup 10; or, the extension direction of the air inlet 25 is consistent with the extension direction of the mounting hole 21. This arrangement allows for greater flexibility in the extension direction of the air inlet 25, meeting different usage requirements and working conditions, and also improving the processing flexibility of the operator.

[0061] In this embodiment, the extending direction of the air inlet 25 is parallel to the central axis of the blade cup 10.

[0062] Example 3

[0063] The difference between the blade cup assembly in Embodiment 3 and Embodiment 1 is that the structure of the retaining bead 30 is different.

[0064] like Figures 10 to 13As shown, the elastic structure 40 is a spring, and the retaining ball 30 includes a ball 31 and a cylinder 32. The ball 31 has a through hole. The cylinder 32 is disposed on the ball 31, and the inner diameter of the cylinder 32 is the same as the inner diameter of the through hole. The cylinder 32 and the ball 31 are coaxially arranged. At least a portion of the cylinder 32 extends into the spring. In this way, the retaining ball 30 can be vented with gas, thereby preventing the retaining ball 30 from rotating and blocking the mounting hole 21 during tool changing, which would affect the discharge of dust and iron filings. At the same time, the cylinder 32 acts as a guide for the extension and contraction of the spring, ensuring that the spring can extend and contract normally.

[0065] Specifically, the outer diameter of the cylinder 32 is the same as the inner diameter of the spring. The gas in the environment surrounding the cutter cup assembly enters the middle of the first channel 12 through the second channel 13 and splits into two paths. One path acts on the tapered hole section at the bottom of the cutter cup 10 to clean dust and iron filings from the hole wall; the other path is mainly used to clean dust and iron filings entering the mounting hole 21. In this way, the aforementioned dust and iron filings are ultimately cleaned by the action of the first channel 12, thereby preventing problems such as tool jamming and tool drop, and thus improving the reliability of the machine tool.

[0066] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0067] The cutter cup assembly has a first channel and an end cap with a mounting hole that communicates with the environment in which the cutter cup assembly is located. The two ends of the first channel communicate with the mounting hole and an inner hole, respectively. An elastic structure is disposed within the mounting hole and applies an elastic force to the retaining bead, causing it to move towards the central axis of the cutter cup. At least a portion of the elastic structure avoids the connection between the mounting hole and the first channel. Thus, when cleaning the cutter cup is required, a cleaning medium or gas is introduced into the mounting hole. This cleaning medium or gas not only cleans the elastic structure and retaining bead within the mounting hole but also enters the first channel to clean the inner hole. This solves the problem of poor cleaning effect on the cutter cup in existing technologies, improves the overall cleanliness of the cutter cup assembly, and prevents contamination of the tool holder or even the machine tool.
