[0002] Shafts are one of the most common types of hardware components. They are mainly used to support transmission parts, transmit torque, and bear loads. According to their structural form, shafts can generally be divided into three categories: plain shafts, stepped shafts, and irregular shafts.

[0003] In the machining process of shaft parts, some complex shafts have holes and slots of various shapes at different positions on the outer circle of the shaft to adapt to the usage requirements of its application environment. Traditionally, the shaft parts are manually placed one by one on machine tools with different functions to perform different hole and slot machining processes. For example, complex shafts first need to be turned and drilled on a lathe, and then the keyway is milled on the shaft parts on a milling machine. For shaft parts with angular requirements, an indexing plate is also added. This machining method requires the purchase of at least two different machine tools, which results in high equipment purchase costs and a large amount of manual labor. The accuracy of the shaft parts is not high due to the change of machine tools. The labor cost is high, the operation efficiency is low, and it is not conducive to mass production in the workshop.

[0036] The specific solutions and embodiments of this utility model will be further described in conjunction with the accompanying drawings, making the technical solution clearer and more understandable.

[0037] like Figure 3a-8As shown in the figure, this embodiment provides a fully automated machining equipment for shaft-type parts. It can be used for machining the outer diameter of shaft-type parts, and is especially suitable for some complex shaft-type parts that are processed through multiple steps.

[0038] As shown in Figures 1-2, the stepped shaft is a complex shaft part manufactured through multiple processes. The entire shaft is in a two-section stepped shape. The inner hollow of the smaller end has a pre-machined inner square hole 2, while the outer circle shows various shapes requiring different machining processes, such as grooves, equally spaced holes, arc keyways, trisected planes, and small bevels. This semi-raw shaft part 1, after outer circle machining, yields a finished shaft part 3 with a complex surface. In this embodiment, the frame 15 of the fully automatic processing equipment has a lower half base made of casting, and the upper half is equipped with multiple functional mechanisms such as power and cutting tools. The outer shell covering the mechanism is made of sheet metal to form a protective cover. A viewing window 7 can be provided on the protective cover to facilitate the operator's observation of the internal system's processing operation. A feeding and conveying mechanism 4 is provided on the left side of the frame 15. The frame 15 is equipped with a material dropping bucket mechanism 16, a positioning mechanism 6, a clamping and conveying mechanism, a power material transfer mechanism, a cutting tool assembly, and a finished product discharge mechanism. The semi-raw shaft parts 1 to be processed are conveyed to the unloading bucket mechanism 16 via the feeding and conveying mechanism 4. After the position is adjusted by the positioning mechanism 6, they are conveyed to the power transfer mechanism via the clamping and conveying mechanism 8. The power transfer mechanism moves to the tool assembly to process the finished shaft parts 3, which then enter the finished product discharge mechanism.

[0039] The power transfer mechanism includes a lead screw assembly 19 and a first power spindle 5 and a second power spindle 11 arranged on the same axis, which are respectively used to move and clamp the two ends of the semi-raw shaft-like part 1. The first power spindle 5 is installed on the nut of the lead screw assembly 19, and the second power spindle 11 is installed on the frame 15. In this embodiment, the first power spindle 5 clamps the large shaft end of the semi-raw shaft-like part 1 to be processed, and the second power spindle 11 clamps the small shaft end of the semi-raw shaft-like part 1 to be processed.

[0040] Furthermore, a cross slide 17 is provided on the frame 15, and the second power spindle 11 is mounted on the cross slide 17. The cross slide 17 is equipped with protective tracks. The second power spindle 11 moves to the designated tool machining position via the cross slide 17, and then the PLC controller controls the tool to move up and down to perform machining operations such as chip cutting or drilling.

[0041] The combined tool set includes combined tool set A9 and combined tool set B10, which are used to machine both ends of the semi-raw shaft-type part 1 to be machined. Combined tool set A9 and combined tool set B10 are equipped with multiple processing tools. These tools include grooving cutters for machining grooves, drills for machining equally spaced holes, milling cutters for machining arc keyways, trisecting planes, etc., and specially shaped tools for machining small bevels, among other tools required for the specific machining process. Depending on the specific machining requirements, one or more different tools are mounted on combined tool set A9 or combined tool set B10. Combined tool sets A9 and B10 are staggered in position and can be adjusted vertically.

[0042] Specifically, the feeding and conveying mechanism 4 is designed to be placed on the left side of the frame 15. The main components of the fully automatic processing equipment are as follows: the partition 14 is located roughly in the middle of the frame 15. The partition 14 has through holes 13. The left side of the partition 14 is equipped with a first power spindle 5, a positioning mechanism 6, a clamping and conveying mechanism 8, and a material dropping bucket mechanism 16. The right side of the partition 14 is equipped with a second power spindle 11, a combination tool A9, a combination tool B10, and a finished product discharge mechanism.

[0043] The feeding and conveying mechanism 4 includes a conveyor belt motor 20, a feeding conveyor belt 21, a telescopic pusher plate 24, two photoelectric sensors 22 for detecting parts on the feeding conveyor belt 21, and a part pausing motor 23. The telescopic pusher plate 24 pushes the semi-raw shaft-type parts 1 to be processed onto the feeding conveyor belt 21. The conveyor belt motor 20 drives the feeding conveyor belt 21 to transport the parts to the feeding port 25. The conveyor belt motor 20 is installed at one end of the feeding conveyor belt 21. Two photoelectric sensors 22 are installed along the entire stroke of the feeding conveyor belt 21, with the latter photoelectric sensor 22 located near the end of the conveying position of the blocking cylinder 23. The semi-raw shaft-type parts 1 to be processed are finally transferred onto the feeding conveyor belt 21 through the reciprocating motion of the telescopic pusher plate 24. The stop cylinder 23 is mainly used to pause the subsequent parts. Specifically, when the previous semi-raw shaft part 1 to be processed is conveyed into the part feeding port 25, the subsequent photoelectric sensor 22 detects the subsequent part until the part is conveyed to the position of the stop cylinder 23. The push rod of the stop cylinder 23 extends to block the subsequent semi-raw shaft part to be processed. After the previous semi-raw shaft part to be processed is installed on the first power spindle 5, the push rod of the stop cylinder 23 retracts, and the conveyor belt motor 20 continues to convey the subsequent semi-raw shaft part to be processed to the part feeding port 25.

[0044] like Figure 4bThe three (or more) telescopic pusher plates 24 shown are arranged in a stepped manner. The telescopic pusher plates 24 are pushed and extended by the cylinders below. The semi-raw shaft parts 1 to be processed are placed on the inclined raw material trough along a specific direction, and pushed by the telescopic pusher plate 24 at the lowest point, gradually moving to the telescopic pusher plate 24 at the highest point, and finally delivering the semi-raw shaft parts 1 to be processed onto the conveyor belt 21. The upper surface of the telescopic pusher plate 24 is preferably designed as an inclined surface.

[0045] As shown in Figure 4c, in one structure, two adjacent telescopic pusher plates 24 are provided with fixed plates. When the blank shaft part 1 to be processed is pushed back by the lowest telescopic pusher plate and reaches the same plane as the lowest fixed plate, the blank shaft part 1 to be processed rolls down onto the lowest fixed plate. Then, the three telescopic pusher plates 24 retract to their original positions. At this time, the blank shaft part 1 to be processed rolls down from the lowest fixed plate onto the second telescopic pusher plate. Then, the three telescopic pusher plates 24 repeat the pushing action once more. After three cycles, the blank shaft part 1 to be processed can be sent to the conveyor belt 21.

[0046] The material feeding hopper mechanism 16 includes a longitudinal telescopic cylinder 33, a first baffle 27, a receiving cylinder 31, a first guide rail pair 28, a lateral displacement cylinder 26, and a second baffle 29. The first baffle 27, which is connected to the longitudinal telescopic cylinder 33, corresponds to the part feeding port 25 at the end of the feeding and conveying mechanism and is located on one side of the first guide rail pair 28. The lateral displacement cylinder 26 drives the slider 32 of the first guide rail pair 28 to slide on the slide rail. The receiving cylinder 31 is provided on the slider 32. The bottom of the receiving cylinder 31 is provided with a square positioning boss 30. The other side of the receiving cylinder 31 is provided with a second baffle 29 connected to the positioning rotary motor 34, corresponding to the part feeding port 25.

[0047] Parts feeding port 25 through Figure 3a The visible window 7 has a first baffle 27 at the outlet end of the part feeding port 25. The first baffle 27 is connected to a longitudinal telescopic cylinder 33 and can move up and down. The receiving cylinder 31 is mounted on the slide rail of the first guide rail pair 28 via a slider 32. A transverse displacement cylinder 26 is connected to one side of the slider 32. The inner bottom of the receiving cylinder 31 is designed with a square positioning boss 30, and there is a second baffle 29 on the other side of the receiving cylinder 31 corresponding to the part feeding port 25.

[0048] The upper edge of the first baffle 27 has a downward relief groove 27a, which facilitates the semi-raw shaft parts 1 to be processed on the discharge port 25 to fall into the receiving cylinder 31.

[0049] The positioning mechanism 6 includes a positioning rotary motor 34, a second guide rail pair 38, a bracket 36, a guide post 40, a cylinder A35, and a cylinder B39. A slider 37 mounted on the second guide rail pair 38 of the frame 15 is connected to the cylinder B39. The bracket 36 and the guide post 40 are mounted on the slider 37 of the second guide rail pair 38. The cylinder A35 on the bracket 36 drives the positioning rotary motor 34 to move up and down along the guide post 40. The chuck on the positioning rotary motor 34 is used to grip the semi-raw shaft-type part 1 to be processed.

[0050] The second baffle 29 is connected to one side of the positioning rotary motor 34. The positioning rotary motor 34 can move up and down along the guide post 40 through the small cylinder A35. The guide post 40 and the cylinder A35 are mounted on the bracket 36. The bracket 36 is mounted on the slider B37. The slider 37 is connected to a cylinder B39. The second guide rail pair 38 is set along the X direction. The cylinder B39 drives the slider B37 and the components on the slider to move along the slide rail of the second guide rail pair 38 in the X direction.

[0051] The clamping and conveying mechanism includes a transmission mechanism and a clamping mechanism, which are further divided into two main parts. The transmission mechanism includes a third guide rail pair 49 and a fourth guide rail pair 48 distributed along the X and Y directions, respectively. The third guide rail pair 49 is mounted on a fixed plate 51 of the frame 15. A slide plate 47 is provided on the slider of the third guide rail pair 49. The slide plate 47 is equipped with the fourth guide rail pair 48 and a dual-axis cylinder 50. The cylinder shaft of the dual-axis cylinder 50 is connected to the fixed plate 51. A cylinder C46 is mounted on the slider 52 of the fourth guide rail pair 48, and the pull rod end of the cylinder C46 is connected to the clamping mechanism.

[0052] Specifically, the fixing plate 51 is installed on one side of the partition 14 of the frame. The slide plate 47 is installed on the third guide rail pair 49 via a slider. The third guide rail pair 49 is fixedly installed on the fixing plate 51. A dual-axis cylinder 50 is installed at one end of the slide plate 47, and the cylinder shaft of the dual-axis cylinder 50 is fixed to the upper end of the fixing plate 51. A fourth guide rail pair 48, a limit seat 45, and a cylinder 46 are installed on the slide plate 47. The cylinder 46 is installed on the slide plate 47 via a cylinder fixing seat 52. Its pull rod is connected to the slider of the linear guide rail 48. Several limit seats 45 are set on the front and rear sides of the cylinder 46 in the extension and retraction direction to limit the extension and retraction stroke of the cylinder 46. A mounting plate 44 is fixed to the end of the pull rod of the cylinder 46. A 90° rotating cylinder 43 is installed on one side of the mounting plate, and a clamping cylinder 41 is installed in combination with the 90° rotating cylinder 43. A three-jaw clamp 42 is installed on the clamping cylinder 41.

[0053] The clamping mechanism includes a 90° rotating cylinder 43, a mounting plate 44, a clamping cylinder 41, and a three-jaw clamp 42. The pull rod end of the cylinder C46, ​​the mounting plate 44, the 90° rotating cylinder 43, and the clamping cylinder 41 equipped with the three-jaw clamp 42 are installed in sequence.

[0054] The finished product unloading mechanism includes a transmission motor, a finished product conveyor belt 18, and a receiving tray 12. The transmission motor drives the finished product conveyor belt 18 to feed the finished shaft parts 3 into the receiving tray 12. An inclined surface is provided at the upper end of the frame corresponding to the area of ​​the second power spindle 11. After processing, the finished product falls into the inclined surface and into the finished product conveyor belt 18.

[0055] The working principle of the fully automated processing equipment for shaft parts in this embodiment is as follows:

[0056] (1) The semi-raw shaft-type parts 1 to be processed are placed in a certain orientation. Figures 4a-4b In the feeding and conveying mechanism 4, the material is conveyed to the conveyor belt 21 by the stepped transmission motion of the telescopic pusher plate 24. The conveyor belt 21 is driven by the conveyor belt motor 20 to transport the semi-raw shaft parts 1 to be processed from one end of the conveyor belt to the other end. During the transmission, the single semi-raw shaft parts 1 to be processed are transported to the end and placed into the part feeding port 25 by the settings of two photoelectric sensors 22, the material blocking cylinder 23 and the PLC program controller on the frame 15.

[0057] (2) In the material feeding mechanism 16, when the semi-raw shaft part 1 to be processed rolls down from the part feeding port 25, its small shaft end is facing down. It is initially blocked by the first baffle 27. The longitudinal telescopic cylinder 33 drives the first baffle 27 to perform telescopic movement, thereby causing the semi-raw shaft part 1 to be processed to leave the part feeding port 25 and fall into the receiving cylinder 31. The second baffle 29 is used for protection when falling.

[0058] (3) When the semi-raw shaft part 1 to be processed falls into the receiving cylinder 31, the positioning mechanism 6 starts to work. The positioning rotary motor 3 is moved to the top of the receiving cylinder 31 by the cylinder B39. The positioning rotary motor 34 moves down under the drive of the cylinder A35 until the chuck on the positioning rotary motor 34 clamps the large shaft end of the semi-raw shaft part 1 to be processed, and slowly rotates to make the inner square hole 2 of the small shaft end of the semi-raw shaft part 1 to be processed coincide with the square positioning boss 30 in the receiving cylinder 31 to achieve positioning.

[0059] (4) After the above actions are completed, the slider 37 and other components of the positioning mechanism 6 on the slider slide on the guide rail of the second guide rail pair 38 under the drive of the cylinder B39, moving away from the position where the unloading barrel mechanism 16 was located when receiving the material. Then, under the drive of the transverse displacement cylinder 26, the unloading barrel mechanism 16 moves the receiving cylinder 31 together with the semi-blank shaft part 1 to be processed inside it to the side of the clamping and conveying mechanism. At this time, the clamping cylinder 41 is in the downward state, and the semi-blank shaft part 1 to be processed is clamped and gripped by the three-jaw chuck 42. Then, cylinder C46 drives mounting plate 44, along with 90° rotating cylinder 43 and clamping cylinder 41, to move upward to a certain position. Then, 90° rotating cylinder 43 drives clamping cylinder 41 to rotate 90°, so that the three-jaw chuck 42 and the semi-raw shaft part 1 to be processed are in a horizontal state. Then, dual-axis cylinder 50 starts working to drive the entire clamping and conveying mechanism to move to a certain position, so that the central axis of the semi-raw shaft part 1 to be processed held and gripped by the three-jaw chuck 42 is aligned with the main axis of the first power spindle 5.

[0060] (5) At this time, the first power spindle 5 rotates slowly and moves to the small shaft end of the semi-blank shaft part 1 to be processed under the drive of the lead screw pair 19. The semi-blank shaft part 1 to be processed is clamped by the automatic clamping head on the first power spindle 5 and then moved back a certain distance. After the clamping and conveying mechanism returns to the initial position, the first power spindle 5 clamps the semi-blank shaft part 1 to be processed and moves together, so that the semi-blank shaft part 1 to be processed extends out through the through hole 13 opened on the partition plate 14 of the frame and reaches the tool processing position of the combined tool body B10. The combined tool body B10 is equipped with multiple process tools, and the combined tool body B10 is positioned relative to the first power spindle 5. The small shaft end of the semi-raw shaft part 1 to be processed is processed one process at a time; until all the required processing processes of the small end of the semi-raw shaft part 1 to be processed are completed, the first power spindle 5 clamps and connects the semi-raw shaft part 1 to be processed with the second power spindle 11 through the through hole 13 opened on the partition plate 14 of the frame. The second power spindle 11 coaxially and synchronously clamps the small shaft end that has been processed on the semi-raw shaft part 1 to be processed. Then the second power spindle 11 moves to move the large shaft end of the semi-raw shaft part 1 to be processed to the position of the tool assembly A9, and processes all the parts that need to be processed in sequence according to the process.

[0061] (6) After the semi-raw shaft part 1 to be processed is processed into finished shaft part 3, the second power spindle 11 moves to the finished product conveyor belt 18 of the finished product discharge mechanism, releases the spindle clamp, and causes the shaped shaft part 3 to fall onto the finished product receiving conveyor belt 18 and be transferred to the final receiving tray 12.

[0062] The aforementioned fully automated machining equipment realizes an integrated, fully automated machining process for shaft parts from the moment they are fed in, achieving a one-time forming process while maintaining consistent coaxiality across all shaft parts. This greatly ensures the overall precision of the parts, reduces manual operation, and simplifies the machining process that traditionally requires multiple machine tools. This embodiment achieves fully automated machining of shaft parts and improves their precision by integrating multiple functions such as turning, milling, drilling, indexing, and coaxial reversing clamping into a single fully automated machine tool.
