Description

Technical Field

[0001] The present invention relates to the technical field of shaft component processing, and in particular to a finishing device for shaft components. Background Art

[0002] In the field of spline gear shaft processing, traditional processing equipment has exposed many problems that need to be solved urgently. In terms of tool switching, the processing procedures of spline gear shafts are complicated. It requires not only fine cutting of the outer circle of the shaft body, but also precise milling of the spline groove, and milling operations for gears of different shapes. However, traditional processing equipment is extremely inconvenient when switching tools during these process changes. For example, when switching from outer circle cutting to spline groove processing, manual disassembly and installation of tools are required. The whole process is cumbersome and time-consuming, seriously slowing down the production rhythm and greatly affecting processing efficiency.

[0003] The unique structure and machining process of spline gear shafts place special demands on chip removal and cooling. The milling process generates a large amount of irregularly shaped debris, which cannot be effectively removed by simply spraying cutting fluid.

[0032] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] like Figures 1-10The finishing device for shaft components shown is arranged on a horizontal displacement frame 2, and a first tool mounting frame 3 and a second tool mounting frame 4 are slidingly provided on the horizontal displacement frame 2 in parallel. The spline gear shaft 1 to be processed is clamped on the side of the horizontal displacement frame 2. The finishing device includes a scraper 5, a keyway milling cutter 6, a forming milling cutter 7, a first tool adjustment assembly, a second tool adjustment assembly and a chip removal assembly. The scraper 5 is mounted on the first tool mounting frame 3, and the first tool adjustment assembly includes a deflection transmission frame 9 sleeved on the first rotating shaft 8. The deflection transmission frame is axially connected to the horizontal displacement frame 2 through the first rotating shaft 8. The two ends of the deflection transmission frame 9 are respectively connected to the first tool mounting frame 3 and the second tool mounting frame 4 for transmission. The second tool adjustment assembly includes a flip frame 11 (such as Figure 6 and Figure 7 As shown) and a transmission device 12 installed on the second tool mounting frame 4, the flip frame 11 is axially connected to the second tool mounting frame 4 through the second rotating shaft 10, the keyway milling cutter 6 and the forming milling cutter 7 are respectively installed on both sides of the flip frame 11, and the chip removal assembly includes a first chip removal mechanism 13 installed on the first tool mounting frame 3 and a second chip removal mechanism 14 installed on the second tool mounting frame 4, the first chip removal mechanism 13 is provided with a vacuum suction nozzle 15, and the second chip removal mechanism 14 is provided with a nozzle 16 for spraying cutting fluid and high-pressure air, and the nozzle 16 is transmission-connected to the transmission device 12.

[0034] When the working tool of this equipment is a scraper 5: the scraper 5 can cut the outer circle of the shaft workpiece (such as the spline gear shaft 1, etc.) when the shaft workpiece (such as the spline gear shaft 1, etc.) rotates, and can also be deflected at a certain angle to perform chamfering, rounding and other operations. The first chip removal mechanism 13 installed on the first tool mounting bracket 3 performs chip removal operations, and sucks iron chips and the like into the chip removal chamber connected to the vacuum suction nozzle 15 through the vacuum suction nozzle 15; when the spline groove of the spline gear shaft 1 needs to be processed, the first tool adjustment component works, and drives the deflection transmission frame 9 to rotate a certain angle on the first rotating shaft 8, synchronously driving the first tool mounting bracket 3 and the second tool mounting bracket 4 to move on the horizontal displacement bracket 2, the first tool mounting bracket 3 retracts, and the second tool mounting bracket 4 extends forward, pushing the second tool mounting bracket 4 to the side close to the spline gear shaft 1. At this time, the keyway milling cutter 6 installed on one side of the second tool mounting bracket 4 starts to work, and the keyway milling cutter 6 performs keyway processing on the surface of the spline gear shaft 1; after completing the keyway processing, the second tool adjustment assembly works to drive the flip frame 11 to rotate ninety degrees around the second rotation axis 10, and the flip frame 11 drives the keyway milling cutter 6 away from the spline gear shaft 1, and the forming milling cutter 7 located on the other side of the flip frame 11 flips to the side close to the spline gear shaft 1. The processing direction of the forming milling cutter 7 is set perpendicular to the processing direction of the keyway milling cutter 6. The forming milling cutter 7 can be used to mill gears of a specific shape. At the same time, when the keyway milling cutter 6 and the forming milling cutter 7 are performing processing operations, the second chip removal mechanism 14 can be used to remove chips and cool the processing parts, that is, the cutting fluid with high-pressure air is sprayed on the processing position through the nozzle 16. During the flipping action, the spraying direction of the nozzle 16 can be adjusted through the transmission device 12. When the cutting processing position changes, the cutting fluid spraying direction is changed synchronously.

[0035] The present invention provides flexible tool switching, improving machining efficiency and precision on the spline gear shaft 1. The design of the first and second tool adjustment assemblies enables rapid and accurate tool switching. The first tool adjustment assembly rotates the deflection transmission frame 9, causing the first and second tool mounting frames 3 and 4 to move on the horizontal displacement frame 2, enabling rapid switching between the scraper 5 and the keyway milling cutter 6 / forming milling cutter 7. The second tool adjustment assembly, through the design of the flip frame 11, enables a 90-degree flip switch between the keyway milling cutter 6 and the forming milling cutter 7, further enhancing tool switching flexibility.

[0036] The present invention is designed with a first chip removal mechanism 13 and a second chip removal mechanism 14, which correspond to different tool mounting brackets respectively. The first chip removal mechanism 13 sucks waste such as iron chips into the chip removal chamber through a vacuum suction nozzle 15 to ensure a clean processing environment. The second chip removal mechanism 14 sprays cutting fluid with high-pressure air added through a nozzle 16 to perform chip removal and cooling operations on the processing part. In particular, during the flipping process of the flip frame 11, the nozzle 16 of the second chip removal mechanism 14 can synchronously switch the spraying position to ensure that the cutting fluid always covers the processing position. During the process of the flip frame 11 rotating ninety degrees around the second rotating axis 10, the nozzle 16 can synchronously switch the spraying position. This design ensures that the cutting fluid always accurately covers the processing position, thereby improving the chip removal efficiency and cooling effect.

[0037] Through precise tool switching and an efficient chip removal and cooling system, the present invention can significantly improve the machining accuracy of shaft components. Rapid tool switching reduces downtime during machining and reduces errors caused by improper tool adjustment.

[0038] The first tool adjustment assembly also includes a first linear drive 17, a push plate 18, a first connecting plate 19, a second connecting plate 20 and a locking device 21. The second connecting plate 20 and the locking device 21 are each provided with two and are located on both sides of the push plate 18. The first rotating shaft 8 is installed on the first tool mounting frame 3 and the second tool mounting frame 4 away from the side of the spline gear shaft 1 and is located between the first tool mounting frame 3 and the second tool mounting frame 4. The first linear drive 17 is fixedly mounted on the horizontal displacement frame 2, and the output end of the first linear drive 17 is fixedly connected to the push plate 18. The length direction of the push plate 18 is consistent with the axial direction of the spline gear shaft 1. The first connecting plate 19 and the second connecting plate 20 are both vertically fixedly mounted on the push plate 18. A rack 22 is provided on the first connecting plate 19, and a first driving gear 23 that can mesh with the rack 22 is provided on the first rotating shaft 8. The first driving gear 23 is transmission-connected to the deflection transmission frame 9, and the second connecting plate 20 is transmission-connected to the locking device 21.

[0039] The first tool adjustment assembly, powered by a first linear actuator 17, pushes the push plate 18 to achieve linear motion. The first connecting plate 19 and the second connecting plate 20 convert the linear motion into rotational motion and lock the tool, respectively, ultimately achieving precise tool adjustment and positioning. This design not only improves tool switching flexibility but also ensures stability and accuracy during machining.

[0040] The first connecting plate 19 on the push plate 18 is provided with a rack 22, which meshes with the first drive gear 23 on the first rotating shaft 8. When the push plate 18 moves, the rack 22 drives the first drive gear 23 to rotate, and then drives the first tool mounting frame 3 and the second tool mounting frame 4 to move in the horizontal direction through the deflection transmission frame 9. The second connecting plate 20 is connected to the locking device 21. The locking device 21 is in an unlocked state when the first tool adjustment assembly is in operation. When the tool is adjusted into place, the locking device 21 locks the tool in a precise position through the second connecting plate 20, ensuring stability and accuracy during the processing. The flexibility of tool switching is improved. The design of the locking device 21 ensures the stable position of the tool during the processing process, reduces the tool displacement caused by vibration or external factors, and the precise tool positioning and stable processing process help to reduce processing errors and improve product quality. At the same time, it reduces the downtime caused by improper tool adjustment and improves the overall processing efficiency.

[0041] The deflection transmission frame 9 is provided with two first slide grooves 24 along its length direction. Each first slide groove 24 is provided with a hinge seat 25 that can be slidably arranged on the first slide groove 24. The two hinge seats 25 are fixedly connected to the first tool mounting frame 3 and the second tool mounting frame 4 respectively.

[0042] When the push plate 18 moves linearly under the drive of the first linear actuator 17, the deflection transmission frame 9 deflects. Simultaneously, the two articulated seats 25 slide within the first chute 24 to accommodate the deflection of the deflection transmission frame 9 and ensure that the transmission connection with the tool mounting frames (i.e., the first tool mounting frame 3 and the second tool mounting frame 4) is not affected. This design ensures that the displacement direction of the tool mounting frames aligns with the pushing direction of the push plate 18, enabling rapid and accurate tool displacement. Furthermore, the deflection of the deflection transmission frame 9 and the sliding mechanism of the articulated seats 25 within the first chute 24 ensure the stability and accuracy of the tool during displacement. This design not only improves the flexibility of tool switching but also ensures stability and precision during machining. Compared to conventional techniques, which may suffer from slow tool adjustment speed and low precision, the deflection transmission frame 9 and articulated seats 25 of the present invention significantly improve machining efficiency and quality.

[0043] The locking device 21 includes a third transmission rod 26, a locking plate 27, a locking plug rod 28 and a first spring 29. A transmission block 30 is fixedly installed on the second connecting plate 20. The locking plate 27 is horizontally slidably arranged on the horizontal displacement frame 2. The third transmission rod 26 and the locking plug rod 28 are both fixedly mounted on the locking plate 27. The directions of the third transmission rod 26 and the locking plug rod 28 are consistent with the length direction of the push plate 18. First chamfers 31 are provided at both ends of the transmission block 30. A second chamfer 32 is provided at one end of the third transmission rod 26 close to the second connecting plate 20. The end of the third transmission rod 26 is always in contact with the surface of the second connecting plate 20 or the transmission block 30. The first spring 29 is arranged between the locking plate 27 and the horizontal displacement frame 2. The two ends of the first spring 29 are respectively fixedly connected to the locking plate 27 and the horizontal displacement frame 2. The first tool mounting frame 3 and the second tool mounting frame 4 are both provided with a locking slot 33 (combined with the locking plug rod 28) matching the locking slot 33. Figure 4 、 Figure 5 and Figure 7 ), a rubber pad is provided on the locking rod 28.

[0044] When the push plate 18 moves linearly under the drive of the first linear driver 17 , the transmission block 30 on the second connecting plate 20 moves accordingly. When the push plate 18 is displaced, the second connecting plate 20 is displaced, and the third transmission rod 26 slides relative to the second connecting plate 20. When the second chamfer 32 of the third transmission rod 26 contacts the first chamfer 31 of the transmission block 30, the third transmission rod 26 drives the locking plate 27 to overcome the elastic force of the first spring 29 and move backward. The locking plate 27 drives the locking plug 28 to disengage the locking slot 33 of the first tool mounting bracket 3 or the second tool mounting bracket 4. When the third transmission rod 26 conflicts with the transmission block 30, it is biased toward the transmission frame 9 for the tool adjustment operation. When the tool adjustment switching is completed, the third transmission rod 26 is again in contact with the surface of the second connecting plate 20. At this time, the third transmission rod 26 is reset under the elastic force of the first spring 29, that is, the locking plate 27 and the locking plug 28 are reset synchronously. At this time, the locking plug 28 is inserted into the locking slot 33 of the first tool mounting bracket 3 or the second tool mounting bracket 4, completing the locking function after the tool adjustment operation. It is worth mentioning that locking slots 33 are provided at both the front and rear ends of the first tool mounting bracket 3 or the second tool mounting bracket 4 so as to achieve a locking effect at different tool adjustment positions.

[0045] Two auxiliary locking grooves 34 are provided on the second connecting plate 20 . The two auxiliary locking grooves 34 are respectively located on both sides of the transmission block 30 . The auxiliary locking grooves 34 are connected to the second connecting plate 20 through an arc angle.

[0046] When the locking rod 28 is inserted into the locking slot 33 of the first tool mounting bracket 3 or the second tool mounting bracket 4 , the auxiliary locking groove 34 can provide additional support or locking points, further enhancing the locking effect.

[0047] The first chip removal mechanism 13 also includes a first mounting frame 35, a transmission channel 36, an inclined channel 37 and a conducting sliding seat 38. The first mounting frame 35 is fixedly mounted on the turning frame 11, the transmission channel 36 is arranged in the first mounting frame 35, the inclined channel 37 is arranged at one end of the first mounting frame 35 away from the turning frame 11, the middle part of the inclined channel 37 is connected with the transmission channel 36, the conducting sliding seat 38 is slidably arranged in the inclined channel 37, and the conducting sliding seat 38 is connected to the turning frame 11 through the transmission device 12. The two ends of the inclined channel 37 are respectively connected to the two nozzles 16, and the two nozzles 16 are respectively inclined to point to the keyway milling cutter 6 and the forming milling cutter 7.

[0048] The transmission channel 36 is externally connected to high-pressure gas and cutting fluid. High-pressure gas can not only be sprayed directly, but also used to increase the spraying speed of the cutting fluid, thereby enhancing the cleaning effect. At the same time, high-pressure gas and cutting fluid can be introduced separately to meet different processing requirements. The inclined channel 37 is connected to the transmission channel 36 to assist in guiding the high-pressure gas and cutting fluid, ensuring that they can accurately reach the tool and processing area. The conducting sliding seat 38 is slidably set in the inclined channel 37, and is used to adjust the spraying direction of the high-pressure gas and cutting fluid, so that it can change the spraying direction after the flipping operation, ensuring that they can evenly cover the tool and processing area. The nozzles 16 on both sides are tilted to point to the keyway milling cutter 6 and the forming milling cutter 7, respectively, for accurately spraying high-pressure gas and cutting fluid.

[0049] The addition of high-pressure gas significantly increases the velocity of the cutting fluid, enabling it to more effectively remove chips and impurities from the tool, maintaining tool cleanliness. High-pressure gas and cutting fluid can be introduced separately, providing more flexible cooling control. Depending on processing requirements, high-pressure gas can be used alone for rapid cooling, or combined with cutting fluid for deep cleaning and cooling. The enhanced cleaning and cooling effects help improve processing efficiency and stability. Clean tools reduce cutting resistance and increase cutting speed, while effective cooling reduces thermal deformation of the tool and workpiece, improving processing accuracy.

[0050] The transmission device 12 includes a first transmission rod 39, a second transmission rod 40 and an inclined transmission rod 41. The inclined direction of the inclined transmission rod 41 is perpendicular to the inclined direction of the inclined channel 37. The inclined transmission rod 41 is transmission-connected to the conductive sliding seat 38 (combined with the inclined transmission rod 41). Figure 8 and Figure 10), an arc-shaped transmission groove 42 is provided on the side wall of the second tool mounting bracket 4, and the arc-shaped transmission groove 42 is arranged on the outer side of the second rotating shaft 10. The distance between the arc-shaped transmission groove 42 and the axis center of the second rotating shaft 10 gradually increases. One end of the first transmission rod 39 is slidably set in the arc-shaped transmission groove 42, and the other end of the first transmission rod 39 is transmission-connected to the second transmission rod 40. The second transmission rod 40 is slidably set on the first mounting bracket 35. The first mounting bracket 35 is provided with a first limiting plate 43 for the second transmission rod 40 to slide, and the other end of the second transmission rod 40 is transmission-connected to the inclined transmission rod 41.

[0051] When the second rotating shaft 10 rotates, the distance between the arc-shaped transmission groove 42 and the axis of the second rotating shaft 10 gradually increases, and the first transmission rod 39 slides in the arc-shaped transmission groove 42. During the flipping operation, the position of the end of the first transmission rod 39 changes relative to the axis of the second rotating shaft 10, thereby realizing the function of pushing or pulling the second transmission rod 40 to move on the first mounting frame 35. The second transmission rod 40 then drives the tilting transmission rod 41 to move, and the tilting transmission rod 41 realizes power transmission through the transmission connection with the conductive sliding seat 38.

[0052] The design of the arc-shaped transmission groove 42 creates a specific relationship between the sliding distance of the first transmission rod 39 and the rotation angle of the second rotating shaft 10, which helps to achieve precise control. That is, after the flip frame 11 flips ninety degrees, the cutting fluid is switched from being sprayed in the direction of one nozzle 16 to being sprayed in the direction of another nozzle 16, driving a specific distance to achieve the switching of the conducting direction of the conducting sliding seat 38.

[0053] The conducting sliding seat 38 is composed of a sealing vertical plate 44, a sealing connecting plate 45 and a connecting channel 46. There are two sealing vertical plates 44 and two connecting channels 46, and they are mirror-imaged in the inclined channel 37. The sealing connecting plate 45 is located between the two sealing vertical plates 44 and is fixedly connected to the two sealing vertical plates 44. The sealing connecting plate 45 can be sealed and matched with the connection between the inclined channel 37 and the transmission channel 36. Two limit strips 47 that interfere with the ends of the connecting channel 46 are provided in the inclined channel 37. An outer sliding groove 48 for avoiding the inclined transmission rod 41 is provided on the side wall of the inclined channel 37. The inclined transmission rod 41 is fixedly connected to the two sealing vertical plates 44. An outer sealing plate 49 that is slidingly connected to it and is sealed therewith is sliding in the outer sliding groove 48. The outer sealing plate 49 is fixedly connected to the inclined transmission rod 41.

[0054] The vertical sealing plates 44 are an essential component of the sealing function of the conducting slide 38, ensuring a tight seal between the conducting slide 38 and the inclined channel 37. The sealing connecting plate 45 provides electrical connection between the inclined channel 37 and the transmission channel 36. The limiting strips 47 limit the range of movement of the conducting slide 38 within the inclined channel 37, ensuring stability during operation.

[0055] When the tilting transmission rod 41 is driven, it moves along with the vertical sealing plate 44 and outer sealing plate 49 to which it is fixed. During the sliding process, the sealing connecting plate 45 maintains a tight seal with the connection between the tilting channel 37 and the transmission channel 36, ensuring the sealing of the entire device. The conducting sliding seat 38, through the combined action of the vertical sealing plate 44, the sealing connecting plate 45, and the outer sealing plate 49, achieves a good seal with the tilting channel 37 and the transmission channel 36. The conducting direction can be automatically adjusted according to the flip position to facilitate operation at different processing locations.

[0056] A telescopic transmission plate 50 is provided on the side of the first transmission rod 39 away from the second tool mounting bracket 4, a telescopic rod is provided between the telescopic transmission plate 50 and the first transmission rod 39, a second spring 52 is sleeved on the telescopic rod, the telescopic transmission plate 50 is fixedly connected to the second transmission rod 40 through a connecting column, a second slide groove 53 is provided on the inclined transmission rod 41 along its length direction, and a transmission push plate is provided on the end of the second transmission rod 40 away from the first transmission rod 39, the transmission push plate is slidably set in the second slide groove 53, and third springs 54 are fixedly provided in the groove bottoms on both sides of the second slide groove 53, and the two third springs 54 are fixedly connected to the transmission push plates.

[0057] When the tilting frame 11 flips, the end of the first transmission rod 39 slides within the arcuate transmission groove 42, causing the first transmission rod 39 to move relative to the first mounting frame 35. The first transmission rod 39, via the second spring 52, drives the telescopic transmission plate 50 to move. The telescopic transmission plate 50, via the connecting column, drives the second transmission rod 40 to slide on the first mounting frame 35. The second transmission rod 40 then drives the transmission push plate, which is fixed to it, to move synchronously. The transmission push plate, via the third spring 54, pushes the tilting transmission rod 41 to move, thereby achieving the transmission function of the conductive sliding seat 38. This allows the conductive sliding seat 38 to slide within the tilting channel 37, achieving the switching function. This design allows the transmission mechanism to have a certain buffering capacity when subjected to external forces, while also allowing the transmission distance to be adjusted as needed. The second slot 53 on the tilting transmission rod 41 provides sliding space for the transmission push plate, allowing the second transmission rod 40 to transmit power to the tilting transmission rod 41 through the transmission push plate sliding within the second slot 53. The third spring 54 provides a buffer and a restoring force for the transmission push plate, which helps to reduce shock and vibration during the transmission process and improve the stability and reliability of the transmission.

[0058] The second tool adjustment assembly also includes a flipping motor 55, a second driving gear 56, a driven gear 57 and a limit frame 58. The flipping motor 55 is fixedly mounted on the side wall of the second tool mounting frame 4, the second driving gear 56 is rotatably mounted on the second tool mounting frame 4, the driven gear 57 is fixedly mounted on the second rotating shaft 10, the second driving gear 56 is engaged with the driven gear 57, the output end of the flipping motor 55 is transmission-connected with the second driving gear 56, the limit frame 58 is fixedly set on the second tool mounting frame 4, and the flipping frame 11 conflicts with the limit frame 58 after flipping into place.

[0059] The tilting motor 55 transmits power through the meshing of the second drive gear 56 and the driven gear 57, causing the tilting frame 11 to tilt. The provision of the stopper 58 ensures that the tilting frame 11 will contact the stopper 58 after being tilted into position, thereby limiting further tilting of the tilting frame 11 and ensuring accurate and stable tilting. This design not only improves the flexibility of tool adjustment but also ensures safe and reliable operation.
