Description

Technical Field

[0001] This invention relates to the technical field of machining, and in particular to a chip flushing device for machining centers. Background Technology

[0002] Chip generation is unavoidable during machining. Timely and effective chip removal is crucial for maintaining machining quality and efficiency.

[0003] Chip flushing effectively prevents damage to workpieces and cutting tools from chips. During the cutting process, a large amount of metal chips are generated. If these chips are not removed in time, they will form scratches on the workpiece surface or between the cutting tools, leading to a decrease in workpiece surface quality, a shortened tool life, and blockage of the cutting edge, affecting the flow of cutting fluid, causing excessive tool temperature, and resulting in decreased machining accuracy. Chip flushing effectively removes chips, maintains the smooth flow of cutting fluid, and improves machining accuracy. Chip flushing also reduces chip accumulation, minimizes chip interference with the cutting tool and workpiece, improves machining efficiency, and reduces machining costs.

[0004] For example, Chinese patent CN109531248A discloses a chip flushing device for a machining center;

[0005] The system includes a storage tank, with a vertically installed first flushing pipe fixedly connected to its lower side wall. A transfer pump is fixedly connected to the side wall of the first flushing pipe. The input end of the transfer pump penetrates the bottom wall of the storage tank and communicates with the interior of the tank. The transfer pump is positioned near the upper end of the first flushing pipe, and its output end penetrates the side wall of the first flushing pipe and communicates with the interior of a second flushing pipe. A second flushing pipe is located inside the first flushing pipe, penetrating the lower end of the first flushing pipe and connected to it via a first connecting device. This system comprehensively cleans debris generated during machining through multi-directional liquid discharge.

[0006] However, the above-mentioned device still has some shortcomings in actual use:

[0007] 1. The above-mentioned device comprehensively cleans the debris generated during machining by dispensing liquid from multiple directions. In practical applications, the milling cutter moves continuously according to the shape of the workpiece. Although the first flushing pipe and the second flushing pipe can move after the movement of the cutter, the position of the first flushing pipe and the second flushing pipe relative to the workpiece changes. This causes the workpiece to block the cutting fluid sprayed from the first flushing pipe and the second flushing pipe, resulting in the cutting fluid not being able to contact the cutter, which affects the cooling and flushing effect.

[0008] 2. The above-mentioned device uses the first flushing pipe and the second flushing pipe to spray cutting fluid to cool the workpiece and the tool and to clean the debris. However, in actual application, different workpieces are of different sizes. Using the same amount of fluid for larger workpieces and smaller workpieces will lead to waste of cutting fluid and increase the cost of machining.

[0009] Therefore, based on the above-mentioned viewpoints, it is of great significance to improve and perfect the chip flushing device of machining center. Improve the angle of the cutting fluid spray and adjust the angle according to the actual machining needs to ensure that the machining area is cooled and the chips are flushed during the cutting process.

Detailed Implementation

[0035] The following is in conjunction with the appendix Figures 1-9 The embodiments of the present invention will be described in detail below.

[0036] This application discloses a chip flushing device for a machining center. It is explained that this invention is mainly used in the machining process. In terms of technical effect, it can avoid the problem that when machining more complex workpieces, the workpiece blocks the sprayed cutting fluid, causing the cutting fluid to be unable to contact the cutting tool, thus affecting the cooling and flushing effect. Furthermore, it can also solve the problem that the cutting fluid cannot be adjusted for different sizes of workpieces, resulting in cutting fluid waste and increased machining costs.

[0037] Example 1:

[0038] Reference Figure 1 , Figure 2 , Figure 3 and Figure 7 As shown, it includes a clamping ring 1, which can be sleeved on the outside of the milling cutter shaft and rotate synchronously with the milling cutter. The clamping ring 1 has a clamping chamber 10 inside, and a clamping unit 2 is installed inside the clamping chamber 10. The clamping unit 2 fixes the clamping ring 1 to the milling cutter.

[0039] The clamping ring 1 is also equipped with a water injection unit 3, which can spray cutting fluid onto the cutting tool and workpiece to cool them down and wash away metal chips, preventing overheating of the workpiece and tool, reducing thermal deformation and tool wear, thereby improving machining accuracy and tool durability. The water injection unit 3 includes a connecting ring 30. The clamping ring 1 has a water injection chamber 31 above the clamping chamber 10. The connecting ring 30 is rotatably mounted on the top of the water injection chamber 31. A water injection pipe 32 is installed on the connecting ring 30 and passes through the clamping ring 1. The cutting fluid enters the water injection chamber 31 through the water injection pipe 32. It should be noted that the water injection pipe 32 is a rigid water pipe and is fixedly installed inside the inner cavity of the machining center by an external structure. During the rotation of the clamping ring 1 with the tool, the connecting ring 30 and the water injection pipe 32 remain fixed and do not affect the entry of the cutting fluid into the water injection chamber 31 through the water injection pipe 32.

[0040] The clamping ring 1 is also equipped with a flushing unit 4 that cooperates with the water injection unit 3. The flushing unit 4 includes a rotating ball 40. The lower end of the clamping ring 1 is provided with a flushing chamber 41 that communicates with the water injection chamber 31. Multiple rotating balls 40 arranged in an arc shape are rotatably arranged at the bottom of the flushing chamber 41. A flushing pipe 42 that communicates with the inside of the rotating ball 40 is provided on the rotating ball 40. After the cutting fluid inside the water injection chamber 31 enters the flushing chamber 41, it cools the tool and the workpiece through the flushing pipe 42 on the rotating ball 40.

[0041] By driving the rotating ball 40 to rotate, the flushing angle of the flushing pipe 42 can be adjusted to adapt to the actual processing needs of different workpieces, ensuring that the cutting fluid can always be in contact with the tool and the workpiece.

[0042] Reference Figure 4 The diagram shows a structure that drives the clamping ring 1 to rotate synchronously with the tool. Specifically, the clamping unit 2 includes a first threaded plate 20, which is rotatably disposed inside the clamping chamber 10. Multiple clamping blocks 21 are equidistantly arranged on the first threaded plate 20 along its axis. The clamping blocks 21 are threadedly connected to the first threaded plate 20. Multiple anti-slip blocks 22 are equidistantly installed on the opposite side of the clamping blocks 21.

[0043] When the first threaded plate 20 rotates, the clamping block 21, which is threadedly connected to it, will move closer to or further away from its axis, adjusting according to the diameter of different tool shafts, and fixing the clamping ring 1 on the shaft.

[0044] The function of the anti-slip block 22 is to increase the friction between the clamping block 21 and the rotating shaft, and to prevent the clamping ring 1 from slipping off during rotation and affecting the tool's machining of the workpiece.

[0045] Reference Figure 4 and Figure 5The diagram shows the structure that drives the first thread to rotate. Specifically, a driving component 23 that drives the first thread plate 20 to rotate is installed on the clamping ring 1. The driving component 23 includes a first gear 230. An installation groove 231 is provided on the clamping ring 1. The first gear 230 is rotatably disposed inside the installation groove 231. A first toothed ring 232 that meshes with the first gear 230 is sleeved on the outside of the first thread plate 20.

[0046] The rotation of the first gear 230 causes the first gear ring 232 to rotate, and the rotation of the first gear ring 232 can drive the first threaded plate 20 to rotate. Then the clamping block 21 on the threaded plate moves closer to its axis.

[0047] Reference Figure 6 and Figure 7 The diagram shows a structural schematic for adjusting the rotation direction of the rotating ball 40. Specifically, the clamping ring 1 is equipped with a drive module 5 that drives the rotating ball 40 to rotate. The drive module 5 includes a second threaded plate 50. The clamping ring 1 is also equipped with a working chamber. The second threaded plate 50 is rotatably disposed inside the working chamber. Multiple push blocks 51 corresponding to the rotating ball 40 are slidably disposed above the second threaded plate 50. The push blocks 51 are threadedly connected to the second threaded plate 50. When the second threaded plate 50 rotates, the push blocks 51 on the second threaded plate 50 will move closer to or away from the axis of the second threaded plate 50, and at the same time, they will move towards the rotating ball. As the direction of 40 moves closer to or away from the rotating ball 40, a push rod 52 is installed on the side of the push block 51 that is close to the rotating ball 40. A connecting rod 53 is hinged to the end of the push rod 52 that is close to the rotating ball 40. The end of the connecting rod 53 that is away from the push rod 52 is engaged with the rotating ball 40. When the push block 51 moves closer to or away from the rotating ball 40, the push rod 52 on the push block 51 will move closer to or away from the rotating ball 40 simultaneously. At this time, it will push the end of the push rod 52 that is hinged to the push rod 52. Since the push rod is engaged with the rotating ball 40, no displacement will occur. At this time, the push rod 52 will rotate, driving the rotating ball 40 to rotate.

[0048] Therefore, rotating the second threaded plate 50 drives the movement of the push block 51, which in turn drives the rotating ball 40 to rotate. The angle of rotation of the rotating ball 40 can be adjusted by adjusting the distance the push block 51 moves.

[0049] Reference Figure 7 The diagram shows a structural schematic of the second threaded plate 50 that drives it to rotate. Specifically, a second driving component 54 for driving the second threaded plate 50 to rotate is installed on the clamping ring 1. The second driving component 54 includes a motor 540. A driving groove is provided on the clamping ring 1, and the motor 540 is disposed in the driving groove. A second gear 541 is installed on the output shaft of the motor 540, and a second toothed ring 542 that meshes with the second gear 541 is installed on the side of the second threaded plate 50.

[0050] When the motor 540 starts, it drives the second gear 541 connected to the output end to rotate. The second gear 541 can rotate the second gear ring 542 that meshes with it. Then the second gear ring 542 drives the second threaded plate 50 to rotate, driving the push block 51 to move. Thus, the rotation angle of the rotating ball 40 is adjusted by the motor 540.

[0051] Reference Figure 7 , Figure 8 and Figure 9 The diagram shows a structural schematic for easy replacement of the rotating ball 40. Specifically, the connecting rod 53 is equipped with a snap-fit ​​component 6 that engages with the rotating ball 40. The snap-fit ​​component 6 is provided because the flushing pipe 42 on the rotating ball 40 has a fixed diameter, and the flow rate of the cutting fluid cannot be adjusted for workpieces of different sizes. This would result in excessive cutting fluid being wasted when machining smaller workpieces, increasing the machining cost. The snap-fit ​​component 6 includes an abutment block 60. A groove is symmetrically provided on the end of the connecting rod 53 near the rotating ball 40. The abutment block 60 is slidably disposed inside the groove by a spring. A mating plate 61 is symmetrically installed on the rotating ball 40, and the end of the abutment block 60 near the mating plate is set as an inclined surface.

[0052] When the rotating ball 40 needs to be replaced, pull the rotating ball 40 down. At this time, the inclined surface on the abutment block 60 on the connecting rod 53 will slide into the groove under the reverse drive of the mating plate 61. The rotating ball 40 will lose the limit of the abutment block 60, making it easy to remove the rotating ball 40.

[0053] When installing the replacement rotating ball 40, hold the rotating ball 40 and drive it toward the connecting rod 53. Then, the abutment block 60 on the connecting rod 53 will move into the groove under the drive of the mating plate 61. Continue to push the rotating ball 40 until the abutment block 60 loses the limit of the mating plate 61. The abutment block 60 slides out under the action of the spring, and the upper end of the abutment block 60 contacts the lower end of the mating plate 61, thus fixing the rotating ball 40.

[0054] Reference Figure 7 , Figure 8 and Figure 9 The diagram shows a structural schematic of fixing the rotating ball 40 to its rotation axis. Specifically, a fixing mechanism 7 for limiting the rotation of the rotating ball 40 is also installed on the clamping ring 1. Since the rotating ball 40 needs to be removed and needs to be able to rotate after installation, the fixing rod 72 needs to be able to rotate while also being easy to disassemble, facilitating the operation of the rotating ball 40. The fixing mechanism 7 includes a mounting shaft 70. The rotating ball 40 has symmetrical fixing grooves on both sides of the clamping ring 1, with the bottom of the groove penetrating the clamping ring 1. The mounting shaft 70 is rotatably disposed in the fixing groove. The mounting shaft 70 has a square groove 71 that communicates with the fixing groove. The rotating ball 40 is symmetrically connected with fixing rods 72 corresponding to the square groove 71.

[0055] When the rotating ball 40 is installed, the fixing rods 72 on both sides of the rotating ball 40 will enter the mounting shaft 70 through the square groove 71 on the mounting shaft 70, and then fix the fixing rods 72 to the mounting shaft 70. Since the mounting shaft 70 can be inside the fixing groove, the rotating ball 40 can be installed easily without affecting the adjustment of the rotation angle of the rotating ball 40.

[0056] Reference Figure 7 , Figure 8 and Figure 9 The diagram shows a structural schematic of the fixing rod 72 being snapped and fixed inside the mounting shaft 70. Specifically, the mounting shaft 70 is equipped with a fixing member 8 for fixing the fixing rod 72. This not only fixes the rotating ball 40 but also allows for easy disassembly and replacement of the rotating ball 40. The fixing member 8 includes a spring telescopic rod 80. The fixing rod 72 has symmetrically arranged sliding grooves, and the spring telescopic rod 80 is disposed inside the sliding grooves. The telescopic end of the spring telescopic rod 80 is provided with a fixing block 81. The square groove 71 on the mounting shaft 70 has symmetrically opened connecting grooves 82 corresponding to the fixing blocks 81.

[0057] When installing the rotating ball 40, after the fixing rod 72 on the rotating ball 40 enters the installation shaft 70, the fixing block 81 on the fixing rod 72 will contact the inner wall of the square groove 71 and slide into the groove until the fixing block 81 corresponds with the connecting groove 82. Then, the fixing block 81 will enter the connecting groove 82 under the drive of the telescopic rod on the spring. Through the cooperation between the fixing block 81 and the connecting groove 82, the fixing rod 72 is fixed in the installation shaft 70, thereby fixing the rotating ball 40.

[0058] Example 2:

[0059] Based on Embodiment 1, in order to further enhance the practicality of this device, a driving component 25 is also proposed, which can drive the first gear 230 to rotate, thereby adjusting the clamping degree of the clamping block 21 through the first gear 230 to ensure that the clamping ring 1 will not fall off.

[0060] Reference Figure 4 and Figure 5 The diagram shows the structure that drives the first gear 230 to rotate. Specifically, the driving component 25 includes a driving shaft 250, which is rotatably mounted in the mounting groove 231. The first gear 230 is connected to the driving shaft 250. A first bevel gear 251 is also mounted on the driving shaft 250. A synchronous shaft 252 with one end passing through the mounting groove 231 is rotatably mounted on the clamping ring 1. A second bevel gear 253 is mounted on one end of the synchronous shaft 252 located inside the mounting groove 231. The first bevel gear 251 and the second bevel gear 253 mesh with each other.

[0061] When the drive shaft 250 rotates, it can drive the second bevel gear 253 to rotate. Then the second bevel gear 253 drives the first bevel gear 251 that meshes with it to rotate. At this time, the synchronous shaft 252 drives the first gear 230 to rotate under the drive of the first bevel gear 251 and meshes with the first gear ring 232. The first gear ring 232 drives the first threaded plate 20 to adjust the sliding distance of the clamping block 21.

[0062] The synchronous shaft 252 is also provided with a polygonal insertion slot 254 along its length. By inserting an external matching shaft into the insertion slot 254, the rotation of the synchronous shaft 252 can be manually adjusted, thereby adjusting the tightness of the clamping block 21.

[0063] During operation: First, the first gear 230 rotates, causing the first gear ring 232 to rotate, which in turn drives the first threaded plate 20 to rotate. Then, the clamping block 21 on the first threaded plate 20 will move closer to or further away from its axis, adjusting according to the diameter of the different tool shafts, and fixing the clamping ring 1 on the rotating shaft of the tool.

[0064] Step 2: The motor 540 starts, driving the second gear 541 connected to the output end to rotate. The second gear 541 drives the second gear ring 542 that meshes with it to rotate. Then the second gear ring 542 drives the second threaded plate 50 to rotate. When the second threaded plate 50 rotates, the push block 51 will move closer to or away from the axis of the second threaded plate 50, and at the same time, it will move closer to or away from the rotating ball 40. The push rod 52 on the push block 51 will move closer to or away from the rotating ball 40 in sync, driving the push rod 52 to rotate, thereby adjusting the rotation angle of the rotating ball 40.

[0065] Step 3: The cutting fluid enters the water injection chamber 31 through the water injection pipe 32. After the cutting fluid in the water injection chamber 31 enters the flushing chamber 41, it cools the tool and workpiece through the flushing pipe 42 on the rotating ball 40.

[0066] Step 4: When replacing the rotating ball 40, pull the rotating ball 40 downwards. The inclined surface on the abutment block 60 on the connecting rod 53 will retract into the groove under the reverse drive of the mating plate 61, making it easy to remove the rotating ball 40. When installing the rotating ball 40, hold the rotating ball 40 and drive it towards the connecting rod 53. Then, the abutment block 60 on the connecting rod 53 will move into the groove under the drive of the mating plate 61. Continue to push the rotating ball 40 until the abutment block 60 loses the limit of the mating plate 61. The abutment block 60 slides out under the action of the spring, and the upper end of the abutment block 60 contacts the lower end of the mating plate 61, fixing the rotating ball 40.

[0067] Step 5: During installation, after the fixing rod 72 on the rotating ball 40 enters the installation shaft 70, the fixing block 81 on the fixing rod 72 will contact the inner wall of the square groove 71 and slide into the groove until the fixing block 81 corresponds to the connecting groove 82. Then, the fixing block 81 will enter the connecting groove 82 under the drive of the telescopic rod on the spring to fix the rotating ball 40.

Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects.
