Description

Technical Field

[0001] The invention relates to the technical field of mechanical processing, in particular to a chip flushing device for a mechanical processing center. Background Art

[0002] The generation of chips is inevitable during machining, and timely and effective chip removal is crucial to maintaining machining quality and efficiency.

[0003] Chip flushing can effectively prevent chips from damaging workpieces and tools. Chips will generate a large amount of metal chips during the cutting process. If these chips are not removed in time, scratches will form on the workpiece surface or between tools, resulting in reduced workpiece surface quality and shortened tool life. Chips will block the cutting edge, affecting the flow of cutting fluid, causing the tool temperature to be too high, resulting in reduced machining accuracy. Chip flushing can effectively remove chips, keep the cutting fluid flowing, and improve machining accuracy. Chip flushing can also reduce chip accumulation, reduce the interference of chips on tools and workpieces, improve machining efficiency, and reduce machining costs.

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

[0005] It includes a liquid storage tank, the lower side wall of the liquid storage tank is fixedly connected with a vertically arranged first flushing pipe, the side wall of the first flushing pipe is fixedly connected with a delivery pump, the input end of the delivery pump penetrates the bottom wall of the liquid storage tank and is connected with the inside of the liquid storage tank, the delivery pump is arranged near the upper end of the first flushing pipe, and the output end of the delivery pump penetrates the side wall of the first flushing pipe and is connected with the inside of the second flushing pipe, the first flushing pipe is provided with a second flushing pipe, the second flushing pipe penetrates the lower end of the first flushing pipe, and the second flushing pipe is connected with the first flushing pipe through a first connecting device. It discharges liquid in multiple directions to comprehensively clean the debris generated by mechanical processing.

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

[0007] 1. The above-mentioned device can comprehensively clean the debris generated by mechanical processing by discharging fluid in multiple directions. In practical applications, the milling cutter is constantly moving according to the shape of the workpiece. Although the first flushing pipe and the second flushing pipe can move with the movement of the tool, the positions of the first flushing pipe and the second flushing pipe relative to the workpiece are changed, which will cause the workpiece to block the cutting fluid sprayed from the first flushing pipe and the second flushing pipe, resulting in the cutting fluid being unable to contact the tool, affecting the cooling and flushing effects.

[0008] 2. The above device utilizes 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 have different sizes. Using the same fluid output for larger 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 the machining center, improve the angle of the cutting fluid spray, adjust the angle according to the actual needs of machining, and ensure that the processing area is always cooled and the chips are flushed during the cutting process.

[0035] The following is combined with Figure 1-Figure 9 Embodiments of the present invention are described in detail.

[0036] The embodiment of the present application discloses a chip flushing device for a machining center, which explains that the present invention is mainly used in the process of mechanical machining. In terms of technical effect, it can avoid the problem that when machining more complex workpieces, the workpiece blocks the sprayed cutting fluid, resulting in the cutting fluid being unable to contact the tool, affecting the cooling and flushing effects; further, it can also solve the problem that the cutting fluid cannot adjust the water volume for workpieces of different sizes, resulting in cutting fluid waste and increased mechanical machining costs.

[0037] Embodiment 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. A clamping chamber 10 is opened inside the clamping ring 1, and a clamping unit 2 is installed inside the clamping chamber 10. The clamping ring 1 and the milling cutter are fixed by the clamping unit 2.

[0039] The clamping ring 1 is also provided with a water injection unit 3, which can spray cutting fluid onto the blade and the workpiece, cool the blade and the workpiece, and wash the metal chips, so as to prevent the workpiece and the tool from overheating, reduce thermal deformation and tool wear, and thus improve machining accuracy and tool durability. The water injection unit 3 includes a connecting ring 30, and the clamping ring 1 is provided with a water injection chamber 31 above the clamping chamber 10. The connecting ring 30 is rotatably arranged at the top of the water injection chamber 31, and a water injection pipe 32 is installed on the connecting ring 30. The water injection pipe 32 passes through the clamping ring 1, and 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 hard water pipe, and is fixedly installed in the inner chamber of the machining center through an external structure. In the process of the clamping ring 1 rotating with the tool, the connecting ring 30 and the water injection pipe 32 are always fixed, and do not affect the cutting fluid from entering the water injection chamber 31 through the water injection pipe 32.

[0040] A flushing unit 4 cooperating with the water injection unit 3 is also installed on the clamping ring 1. The flushing unit 4 includes a rotating ball 40. A flushing chamber 41 connected to the water injection chamber 31 is opened at the lower end of the clamping ring 1. A plurality of arc-shaped rotating balls 40 are rotatably arranged at the bottom of the flushing chamber 41. The rotating ball 40 is provided with a flushing pipe 42 connected to the inside of the rotating ball 40. After the cutting fluid in the water injection chamber 31 enters the flushing chamber 41, the tool and the workpiece are cooled 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 meet the needs of actual processing of different workpieces, ensuring that the cutting fluid can always be in contact with the tool and the workpiece.

[0042] Reference Figure 4 As shown, it is a schematic diagram of the structure that drives the clamping ring 1 to rotate synchronously with the tool; specifically, the clamping unit 2 includes a first threaded plate 20, the first threaded plate 20 is rotatably arranged inside the clamping chamber 10, and a plurality of 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, and a plurality of anti-sliding blocks 22 are equidistantly installed on the opposite side of the clamping block 21.

[0043] When the first threaded plate 20 rotates, the clamping block 21 threadedly connected thereto will move closer to or farther from the axis direction thereof, and the clamping ring 1 is fixed on the axis by adjusting according to the diameter of different tool shafts.

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

[0045] Reference Figure 4 and Figure 5As shown, it is a schematic diagram of the structure for driving the first thread to rotate; specifically, a driving member 23 for driving the first thread plate 20 to rotate is installed on the clamping ring 1, and the driving member 23 includes a first gear 230. A mounting groove 231 is opened on the clamping ring 1, and the first gear 230 is rotatably set inside the mounting groove 231. The first thread plate 20 is sleeved on the outer side with a first gear ring 232 meshing with the first gear 230.

[0046] The first gear 230 rotates with the first gear ring 232 , and the rotation of the first gear ring 232 can drive the first threaded plate 20 to rotate, and then the clamping block 21 on the threaded plate approaches its axial direction.

[0047] Reference Figure 6 and Figure 7 As shown, that is, a schematic diagram of the structure for adjusting the rotation direction of the rotating ball 40; specifically, a driving module 5 for driving the rotating ball 40 to rotate is provided on the clamping ring 1, and the driving module 5 includes a second threaded plate 50. A working chamber is also provided on the clamping ring 1, and the second threaded plate 50 is rotatably arranged inside the working chamber. A plurality of propulsion blocks 51 corresponding to the rotating ball 40 are slidably arranged above the second threaded plate 50, and the propulsion blocks 51 are threadedly connected to the second threaded plate 50. When the second threaded plate 50 rotates, the propulsion blocks 51 on the second threaded plate 50 will approach or move away from the axis of the second threaded plate 50, and at the same time will move toward the rotating ball When the push block 51 approaches or moves away from the rotating ball 40, a push rod 52 is installed on the side of the push block 51 close to the rotating ball 40, and a connecting rod 53 is hingedly provided at one end of the push rod 52 close to the rotating ball 40. The end of the connecting rod 53 away from the push rod 52 is snap-connected with the rotating ball 40. When the push block 51 approaches or moves away from the rotating ball 40, the push rod 52 on the push block 51 will synchronously approach or move away from the rotating ball 40, and at this time, one end of the push rod 52 hingedly connected to the push rod 52 will be pushed. Since the drag rod is snap-connected 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 propulsion block 51 to move, which can drive the rotating ball 40 to rotate. The rotation angle of the rotating ball 40 can be adjusted by adjusting the moving distance of the propulsion block 51.

[0049] Reference Figure 7 As shown, it is a schematic diagram of the structure for driving the second threaded plate 50 to rotate; specifically, a driving member 54 for driving the second threaded plate 50 to rotate is installed on the clamping ring 1, and the driving member 54 includes a motor 540. A driving groove is opened on the clamping ring 1, and the motor 540 is arranged in the driving groove. A second gear 541 is installed on the output shaft of the motor 540, and a second gear ring 542 meshing with the second gear 541 is installed on the side of the second threaded plate 50.

[0050] The motor 540 is started, driving the second gear 541 connected to the output end to rotate. The second gear 541 can rotate with the second gear ring 542 meshing with it, and then the second gear ring 542 rotates with the second threaded plate 50, driving the propulsion block 51 to move, thereby adjusting the rotation angle of the rotating ball 40 through the motor 540.

[0051] Reference Figure 7 , Figure 8 and Fig. 9 As shown, it is a schematic diagram of the structure for convenient replacement of the rotating ball 40; specifically, the connecting rod 53 is provided with a clamping member 6 for driving the connecting rod 53 and the rotating ball 40 to be clamped and installed. The reason for providing the clamping member 6 is that the flushing pipe 42 on the rotating ball 40 has a fixed diameter, and the flow rate of the cutting fluid sprayed cannot be adjusted for workpieces of different sizes, which will result in excessive cutting fluid being wasted when processing smaller workpieces, increasing the processing cost of the workpiece. The clamping member 6 includes an abutment block 60, and a sliding groove is symmetrically provided at one end of the connecting rod 53 close to the rotating ball 40. The abutment block 60 is slidably arranged inside the sliding groove by a spring, and a matching plate 61 is symmetrically installed on the rotating ball 40, and an end of the abutment block 60 close to the matching slide plate is set as an inclined surface.

[0052] When the rotating ball 40 needs to be replaced, the rotating ball 40 is pulled downward. At this time, the inclined surface on the abutment block 60 on the connecting rod 53 will slide and retract into the slide groove under the reverse drive of the matching plate 61, and the rotating ball 40 loses the limit of the abutment block 60, making it convenient to remove the rotating ball 40.

[0053] When installing the replaced 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 inside of the slide groove under the drive of the matching plate 61, and continue to push the rotating ball 40 until the abutment block 60 loses the limit of the matching 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 matching plate 61 to fix the rotating ball 40.

[0054] Reference Figure 7 , Figure 8 and Fig. 9 As shown, it is a schematic diagram of the structure for fixing the rotating axis of the rotating ball 40; specifically, a fixing mechanism 7 for limiting 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 and be easy to disassemble, so as to facilitate the operation of the rotating ball 40. The fixing mechanism 7 includes a mounting shaft 70, and fixing grooves with the bottom penetrating the clamping ring 1 are symmetrically opened on both sides of the rotating ball 40 on the clamping ring 1. The mounting shaft 70 is rotatably set in the fixing groove, and a square groove 71 connected to the fixing groove is opened on the mounting shaft 70. 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 installation shaft 70 through the square grooves 71 on the installation shaft 70, and then the fixing rods 72 and the installation shaft 70 will be fixed. Since the installation shaft 70 can be inside the fixing groove, the rotating ball 40 can be easily installed without affecting the adjustment of the rotation angle of the rotating ball 40.

[0056] Reference Figure 7 , Figure 8 and Fig. 9 As shown, it is a schematic diagram of the structure of clamping and fixing the fixing rod 72 inside the installation shaft 70; specifically, the installation shaft 70 is provided with a fixing member 8 for fixing the fixing rod 72, which can be easily disassembled while fixing the rotating ball 40, so as to facilitate the replacement of the rotating ball 40. The fixing member 8 includes a spring telescopic rod 80, and the fixing rod 72 is symmetrically provided with a slide groove, the spring telescopic rod 80 is arranged inside the slide groove, and a fixing block 81 is arranged at the telescopic end of the spring telescopic rod 80, and a connecting groove 82 corresponding to the fixing block 81 is symmetrically opened inside the square groove 71 on the installation shaft 70.

[0057] When installing the rotating ball 40, after the fixing rod 72 on the rotating ball 40 enters the interior of 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 interior of the slide groove until the fixing block 81 corresponds to the connecting groove 82. Then, the fixing block 81 will enter the connecting groove 82 driven by the telescopic rod on the spring, and the fixing rod 72 will be fixed in the installation shaft 70 through the cooperation between the fixing block 81 and the connecting groove 82, thereby fixing the rotating ball 40.

[0058] Embodiment 2:

[0059] On the basis of the first embodiment, in order to further enhance the practicality of the device, a driving member 3 25 is also proposed, which can drive the first gear 230 to rotate, and then adjust 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 As shown, it is a schematic diagram of the structure for driving the first gear 230 to rotate; specifically, the driving member 25 includes a driving shaft 250, which is rotatably arranged in the mounting groove 231, the first gear 230 is connected to the driving shaft 250, and a first bevel gear 251 is also arranged on the driving shaft 250, and a synchronous shaft 252 with one end passing through the mounting groove 231 is rotatably installed on the clamping ring 1, and a second bevel gear 253 is installed at one end of the synchronous shaft 252 located inside the mounting groove 231, and the first bevel gear 251 and the second bevel gear 253 are meshed with each other.

[0061] When the driving shaft 250 rotates, it can drive the second bevel gear 253 to rotate, and then the second bevel gear 253 drives the first bevel gear 251 meshing with it to rotate. At this time, the synchronization shaft 252, driven by the first bevel gear 251, drives the first gear 230 to rotate and mesh with the first gear ring 232, and the first gear ring 232 drives the first threaded plate 20 to adjust the sliding distance of the clamping block 21.

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

[0063] During operation: In the first step, the first gear 230 rotates with the first gear ring 232, driving the first threaded plate 20 to rotate, and then the clamping block 21 on the first threaded plate 20 will approach or move away from its axial direction, and adjust according to the diameter of the tool shaft to fix the clamping ring 1 on the rotating shaft of the tool.

[0064] Step 2: The motor 540 is started, driving the second gear 541 connected to the output end to rotate, and the second gear 541 rotates with the second gear ring 542 meshing with it, and then the second gear ring 542 rotates with the second threaded plate 50. When the second threaded plate 50 rotates, the thrust block 51 will approach or move away from the axis of the second threaded plate 50, and at the same time, it will approach or move away from the direction of the rotating ball 40. The push rod 52 on the thrust block 51 will synchronously approach or move away from the rotating ball 40, driving the push rod 52 to rotate, so as to adjust 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, the flushing pipe 42 on the rotating ball 40 cools down the tool and the workpiece.

[0066] Step 4: When replacing the rotating ball 40, pull the rotating ball 40 downward, and the inclined surface on the abutment block 60 on the connecting rod 53 will be retracted into the slide groove under the reverse drive of the matching plate 61, so as to facilitate the removal of the rotating ball 40. When installing the rotating ball 40, hold the rotating ball 40 and drive it toward the direction of the connecting rod 53. Then, the abutment block 60 on the connecting rod 53 will move to the inside of the slide groove under the drive of the matching plate 61, and continue to push the rotating ball 40 until the abutment block 60 loses the limit of the matching plate 61, and 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 matching plate 61 to fix the rotating ball 40.

[0067] Step 5: During installation, after the fixing rod 72 on the rotating ball 40 enters the interior of 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 interior of the slide groove until the fixing block 81 corresponds to the connecting groove 82. Then, the fixing block 81 will enter the connecting groove 82 driven by the telescopic rod on the spring to fix the rotating ball 40.

[0068] It is obvious to those skilled in the art that the present invention is not limited to the details of the above-mentioned exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive.

[0069] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
