Description

Technical Field

[0001] The invention relates to the field of machine tool processing, and in particular to a lightweight, efficient slot processing device for a rotating shaft and a processing method thereof. Background Art

[0002] In the field of modern mechanical processing, the shaft is a key component in various mechanical equipment, and its processing accuracy and efficiency directly affect the performance of the entire equipment; the shaft high-efficiency groove refers to a groove structure with a specific shape and size processed on the shaft surface. These grooves are usually used to install various transmission components, seals or realize other specific functions.

[0003] In the actual shaft processing process, the workpiece is often long and the excess part needs to be cut off to reach the designed size. However, traditional workpiece clamping usually uses a three-jaw chuck, which has many disadvantages. Since long-axis workpieces are prone to shaking during cutting, in order to ensure processing stability, the three-jaw chuck often needs to clamp the workpiece deeper, resulting in a shorter exposed section of the workpiece left on the three-jaw chuck after cutting, which needs to be manually removed and clamped again.

[0004] In the prior art, for example, the patent with publication number CN220920953U discloses a three-jaw chuck for a CNC lathe. When clamping a workpiece, the electric motor is started to drive the screw to rotate, and the screw drives the moving block, and then drives the connecting block and the clamping block to move, so as to clamp the workpiece. Since multiple clamping blocks can be driven separately, special-shaped workpieces can also be fixed well. However, when the above-mentioned chuck faces a longer workpiece and needs to cut off the excess part, in order to prevent the long axis from shaking during cutting, although the workpiece can be clamped by the clamping block, it lacks an effective auxiliary support structure, and it is difficult to ensure stable processing when clamping deeper. Moreover, after the cutting is completed, there is no convenient design for removing the workpiece, and manual operation is required.

[0005] When manually removing the workpiece, it is impossible to accurately control the length of the workpiece being pulled out, which will have a great impact on the accuracy of subsequent re-clamping and processing, increase the complexity of the processing steps, and reduce production efficiency.

[0006] Therefore, based on the above-stated viewpoints, there is still room for optimization in the prior art method of processing grooves on rotating shafts. Summary of the invention

DETAILED DESCRIPTION

[0039] The following combination Figures 1 to 10 Embodiments of the present invention are described in detail.

[0040] The embodiment of the present application discloses a lightweight and efficient groove processing device for a rotating shaft and a processing method thereof; it should be noted that the present application is capable of firmly clamping the rotating shaft during the process of lightweight and efficient groove processing on the rotating shaft to ensure the stability of the rotating shaft during cutting; and, after the cutting is completed, the rotating shaft can be precisely moved and adjusted to meet further cutting requirements. At the same time, for a rotating shaft with a longer length, its end can also be supported to ensure that the rotating shaft does not shake during processing.

[0041] Example 1: Reference Figure 1 As shown, it includes a base 1, a sliding plate 10, a tool holder 11, a support plate 12 and a clamping unit 2. The sliding plate 10 is arranged on one side of the base 1, and the tool holder 11 is slidably arranged on one side of the sliding plate 10. The tool holder 11 can be driven by an external driving device to move on one side of the sliding plate 10.

[0042] A support plate 12 is provided on one side of the base 1, and a clamping unit 2 for clamping a workpiece is provided on one side of the support plate 12. The support plate 12 is used to support the clamping unit 2. An external driving device can drive the clamping unit 2 and the workpiece to rotate under the limit of the support plate 12. At this time, the tool holder 11 carries the cutting tool installed thereon to move on the sliding plate 10 to cut the workpiece clamped by the clamping unit 2.

[0043] It should be noted that the “workpiece” mentioned in the above implementation process is a rotating shaft, and the workpieces in the subsequent implementation process are all rotating shafts unless otherwise specified.

[0044] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the clamping unit 2 is used to clamp the workpiece; specifically, the clamping unit 2 includes a main cylinder 20, a slide groove 21, a clamping plate 22, a roller member 4, a threaded disk 23, a sliding groove 24, a sliding plate 25, a rubber plate 26, a rectangular groove 27 and a push spring 28. The main cylinder 20 is rotatably arranged at the upper end of the support plate 12, and the main cylinder 20 can rotate under the limit of the support plate 12.

[0045] A plurality of slide grooves 21 are provided on one side of the main cylinder 20, a clamping plate 22 is slidably arranged in the slide groove 21, and a roller member 4 is rotatably arranged on the inner side of the clamping plate 22, the slide groove 21 can limit and guide the clamping plate 22, and the clamping plate 22 can move toward or away from the axis of the main cylinder 20 under the limit of the slide groove 21, the clamping plate 22 clamps the workpiece through the roller member 4, and the roller member 4 can drive the clamped workpiece to move in the left and right directions.

[0046] The threaded disk 23 arranged on the inner wall of the main cylinder 20 is rotated, and one side of the clamping plate 22 extends toward the threaded disk 23 and is threadedly connected thereto. That is, when the threaded disk 23 is driven to rotate by an external driving device, it can drive the corresponding clamping plate 22 to move under the limit of the slide groove 21 to clamp the workpiece.

[0047] A sliding groove 24 is also provided on the opposite side of the clamping plate 22, and a sliding plate 25 is slidably arranged in the sliding groove 24. A rubber plate 26 is provided at one end of the sliding plate 25 outside the sliding groove 24, and a rectangular groove 27 is provided in the clamping plate 22. One side of the sliding plate 25 extends into the rectangular groove 27, and a pushing spring 28 is provided between the sliding plate 25 and the rectangular groove 27. The sliding plate 25 can move toward or away from the axis of the main cylinder 20 under the limit of the sliding groove 24.

[0048] The roller member 4 and the rubber plate 26 are in contact with the outside of the workpiece and clamp it, and in the initial state, the push spring 28 drives the sliding plate 25 to move toward the axis of the main cylinder 20, and the sliding plate 25 is driven by the push spring 28 to clamp the workpiece through the rubber plate 26, that is, the workpiece can be firmly clamped by the roller member 4 and the rubber plate 26 at this time, so that the stability of the workpiece during cutting is guaranteed.

[0049] Continue to refer to Figure 4 and Figure 5 As shown, a sliding cavity 30 is also provided on the inner side of the clamping plate 22, and an adjusting unit 3 is slidably provided in the sliding cavity 30 for driving the workpiece to move and adjust; specifically, the adjusting unit 3 includes a sliding cavity 30, a sliding rack 31 and a contact plate 32, and several circular grooves are provided on the inner side of the clamping plate 22 and are connected with the sliding groove 24, and the roller member 4 is rotatably installed in the circular groove, and the circular groove is connected with the corresponding sliding cavity 30, and the roller member 4 can rotate under the limit of the circular groove.

[0050] A sliding rack 31 is slidably arranged in the sliding cavity 30, and the sliding rack 31 is meshed with the roller member 4. The sliding rack 31 can move left and right in the sliding cavity 30 when driven by an external force, and can drive the roller member 4 to rotate during movement, thereby indirectly driving the workpiece to move left and right.

[0051] The sliding plate 25 is provided with a contact plate 32 on one side of the sliding plate 25 located in the sliding groove 24, and the contact plate 32 is meshed with the sliding rack 31, that is, when the sliding rack 31 moves, the teeth of the sliding rack 31 will contact the contact plate 32, and drive the sliding plate 25 to move in the direction of the axis of the main cylinder 20 through the contact plate 32, and during the movement of the sliding rack 31, the teeth of the sliding rack 31 are constantly in contact with the contact plate 32, that is, the contact plate 32 will alternately contact with the teeth of the sliding rack 31, so that the sliding plate 25 reciprocates under the limiting guidance of the sliding groove 24, and when the sliding plate 25 moves in the direction away from the axis of the main cylinder 20, the workpiece is not limited by the rubber plate 26 at this time, so the roller member 4 can drive the workpiece to move in the left and right directions, and because the sliding plate 25 reciprocates, the workpiece also moves intermittently, so that the movement accuracy is guaranteed.

[0052] When the workpiece is being cut, the resistance plate 32 is driven by the sliding rack 31 to cause the sliding plate 25 to continue clamping the workpiece to ensure the stability of the workpiece. Only after the workpiece is cut and the extension section of the workpiece needs to be extended, the sliding rack 31 will drive the roller member 4 to rotate according to the above steps to move the workpiece.

[0053] Reference Figure 6 and Figure 7 As shown, the roller member 4 is used to drive the workpiece to move; specifically, the roller member 4 includes a circular shaft 40, a sliding gear 41, a circular ring 42, a clamping groove 43, a clamping cavity 44, a clamping plate 45 and a reset spring 46. The circular shaft 40 is rotatably arranged inside the circular groove, and a sliding gear 41 is sleeved on the outer side of the circular shaft 40. The sliding gear 41 is meshed with the sliding rack 31. The circular ring 42 is rotatably sleeved on the outer side of the circular shaft 40, that is, the sliding rack 31 can drive the circular shaft 40 to rotate through the sliding gear 41, so that the circular shaft 40 can rotate in the circular groove, and the circular ring 42 can rotate on the outer side of the circular shaft 40.

[0054] The circular ring 42 is provided with a plurality of engaging grooves 43 distributed along its axis, and the outer side of the circular shaft 40 is provided with a plurality of engaging cavities 44 corresponding to the engaging grooves 43. A engaging plate 45 located in the corresponding engaging groove 43 is slidably arranged in the engaging cavity 44, and a return spring 46 is arranged between the engaging plate 45 and the inner wall of the engaging cavity 44. In the initial state, when the sliding plate 25 clamps the workpiece, the circular shaft 40 drives the outer engaging plate 45 to slide out of the corresponding engaging groove 43, and moves to the next engaging groove 43 under the driving of the corresponding return spring 46. This is to ensure that the round shaft 40 can still rotate after the workpiece is limited by the sliding plate 25, so that the sliding rack 31 can continue to move. When the sliding plate 25 no longer limits the workpiece, the round shaft 40 can drive the circular ring 42 to rotate through the clamping cavity 44, the reset push spring 46, the clamping plate 45, and the clamping groove 43, and the circular ring 42 can drive the workpiece to move in the left and right directions. Similarly, when the sliding plate 25 continues to clamp the outside of the workpiece, the main shaft can "idle", and the circular ring will not rotate because it is in contact with the outside of the workpiece.

[0055] Example 2: Reference Figure 8 and Fig. 9 As shown, on the basis of the first embodiment, in order to be able to drive the threaded disk 23 and the sliding rack 31 to move, a driving unit 5 is arranged in the main cylinder 20; specifically, the driving unit 5 includes a driving ring gear 50, a cross plate 51, a driving motor 52, a driving gear 53, a driving cylinder 54, a structural groove 55, a driving ring 56 and a telescopic shaft 57. The driving groove is opened in the middle of the threaded disk 23, and the driving ring gear 50 is arranged on the inner side wall of the driving groove. The cross plate 51 is arranged on the inner side wall of the main cylinder 20, and the end of the cross plate 51 is provided with a driving motor 52 located in the middle of the main cylinder 20, that is, the cross plate 51 is used to support the driving motor 52, and when the clamping plate 22 is driven to move by the threaded plate, since the extension section of the cross plate 51 is staggered with the clamping plate 22, the clamping plate 22 will not collide with the cross plate 51 when moving.

[0056] The output end of the driving motor 52 extends into the driving groove and is sleeved with a driving gear 53 that meshes with the driving ring gear 50. The driving motor 52 drives the driving ring gear 50 to rotate through the driving gear 53, so that the driving ring gear 50 can drive the threaded disk 23 to rotate, thereby realizing the function of the threaded disk 23 driving the clamping plate 22 to clamp and release the workpiece.

[0057] A driving cylinder 54 is also arranged on the inner wall of the main cylinder 20 through a cylinder seat. A structural groove 55 that penetrates the sliding cavity 30 is opened on one side of the clamping plate 22 located in the main cylinder 20. A driving ring 56 is sleeved on the telescopic end of the driving cylinder 54. Several telescopic shafts 57 corresponding to the structural groove 55 are arranged on the outside of the driving ring 56. The end of the telescopic shaft 57 extends into the structural groove 55 and the sliding cavity 30 to engage with one end of the sliding rack 31.

[0058] That is, the driving cylinder 54 can drive the sliding rack 31 to move in the left and right directions through the telescopic shaft 57, so that the sliding rack 31 can synchronously drive the roller member 4 to rotate and the sliding plate 25 to move, and when the clamping plate 22 is driven by the threaded disk 23 to move, the distance between the clamping plates 22 will gradually decrease. At this time, the telescopic shaft 57 will also follow the movement of the clamping plate 22 to adaptively retract, so that after the clamping plate 22 clamps the workpiece, the driving cylinder 54 can still indirectly drive the roller member 4 and the sliding plate 25 to move.

[0059] Example 3: Reference Figure 6 As shown, on the basis of Example 1 and Example 2, in order to ensure that the ends of a workpiece with a longer length can be supported during processing, a support assembly 6 is provided on the base 1. Specifically, the support assembly 6 includes a support groove 60, a telescopic plate 61 and a supporting device 62. The support groove 60 is opened on the base 1, and a telescopic plate 61 is slidably arranged in the support groove 60. The end of the telescopic plate 61 is installed with a supporting device 62 for supporting the outer side of the workpiece, that is, after the workpiece is installed on the clamping unit 2, the outer side of the workpiece will contact the supporting device 62. According to the diameter of the workpiece, the supporting device 62 drives the telescopic end of the telescopic plate 61 to perform adaptive telescoping, and when the workpiece is driven to rotate, the telescopic plate 61 will drive the supporting device 62 to support the workpiece, thereby ensuring that the workpiece does not shake during processing.

[0060] In addition, the present invention also provides a lightweight shaft high-efficiency slot processing method, comprising the following steps:

[0061] S1, workpiece installation: the workpiece is installed on the clamping unit 2, and then the workpiece is clamped by the clamping plate 22 and the roller member 4.

[0062] S2, workpiece cutting: driving the main cylinder 20 to rotate the workpiece under the limit of the support plate 12, and then starting the tool holder 11 to move and cut the workpiece.

[0063] S3, workpiece adjustment: after cutting is completed, the roller member 4 is driven to rotate so that the workpiece is driven to move, and then the cutting tool on the tool holder 11 continues to cut the workpiece.

[0064] S4, workpiece disassembly: after the workpiece is cut, the clamping plate 22 and the roller member 4 are driven to no longer clamp the workpiece, and the workpiece is removed.

[0065] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, 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, the embodiments should be considered as exemplary and non-restrictive in all respects.

[0066] 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. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
