[0002] Shaft parts are one of the typical parts often encountered in hardware accessories. They are mainly used to support transmission components, transmit torque and bear loads. According to the different structural forms of shaft parts, they can generally be divided into three categories: smooth shafts, stepped shafts and special-shaped shafts.

[0003] In the processing of shaft parts, some complex shafts will have holes and grooves of various shapes at different positions on the outer circle of the shaft to adapt to the use requirements of their application environment. Traditional processing is to manually place the shaft parts one by one on machine tools with different functions to perform different hole and groove processing procedures. For example, a complex shaft first needs a lathe to turn and drill the stepped shaft, and then replace the milling machine to mill the keyway on the shaft parts. If there are angle requirements, an additional dividing plate is required, etc. This processing method requires the purchase of at least two different equipment and machine tools. The cost of purchasing equipment is high, and the manual workload is large.

[0036] The specific embodiments of the present invention are further described in conjunction with the accompanying drawings to make the technical solution clearer and more understandable.

[0037] like Figure 3a-8As shown, this embodiment provides a fully automatic processing equipment for shaft parts, which can be used for the outer circle processing of shaft parts, especially for some complex shaft parts processed by multiple processes.

[0038] The stepped shaft shown in Figure 1-2 is a complex shaft part processed through multiple processes. The whole shaft is in a two-stage stepped shape. The small end is designed with an inner square hole 2 that is initially processed. The outer circle can be seen to be processed with grooves, equally divided holes, arc keyways, three-divided planes, small bevels and many other shapes that require different processing steps. This semi-rough embryonic shaft part 1 to be processed is processed to obtain a finished shaft part 3 with a complex surface after the outer circle is processed. The frame 15 of the fully automatic processing equipment of this embodiment has a casting base in the lower half, and after the upper half is arranged with multiple functional mechanisms such as power and tools, the outer shell of the mechanism is protected by sheet metal to form a protective cover. A visual window 7 can be set on the protective cover to facilitate the operator to observe the processing and operation of the internal system during the processing. A feeding and conveying mechanism 4 is provided on the left side of the frame 15, and a material dropping barrel mechanism 16, a positioning mechanism 6, a clamping and conveying mechanism, a power material moving mechanism, a tool assembly and a finished product discharge mechanism are provided on the frame 15. The semi-embryo shaft parts 1 to be processed are transmitted to the blanking bucket mechanism 16 through the feeding and conveying mechanism 4, and after the position is adjusted by the positioning mechanism 6, they are transmitted to the power material moving mechanism through the clamping and conveying mechanism 4. The power material moving mechanism moves to the tool assembly for processing, and the finished shaft parts 3 obtained enter the finished product discharging mechanism.

[0039] The power material moving mechanism includes a screw pair 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-embryocotyl part 1. The first power spindle 5 is installed on the nut of the screw pair 19, and the second power spindle 11 is installed on the machine tool 1. In this embodiment, the first power spindle 5 clamps the large axis end of the semi-embryocotyl part 1 to be processed, and the second power spindle 11 clamps the small axis end of the semi-embryocotyl part 1 to be processed.

[0040] Furthermore, the machine tool 1 is provided with the second power spindle 11 mounted on a cross slide 17, and a protective track is provided on the cross slide 17. The second power spindle 11 moves to a designated tool processing position through the cross slide 17, and then the PLC controller controls the tool to move up and down to perform chip cutting or hole turning and other processing operations.

[0041] The combination tool specifically includes combination tool specific A9 and combination tool specific B10, which are respectively used to process the two ends of the semi-embryo-type parts 1 to be processed. The combination tool specific A9 and combination tool specific B10 are provided with a plurality of process tools. The combination tool specifically includes a grooving tool for processing grooves, a drill bit for processing equally divided holes, a milling cutter for processing arc keyways, three-divided planes, etc., a special-shaped tool for processing small bevels, and other various tools required for processing. According to specific processing requirements, one or more different tools are installed on the combination tool specific A9 or the combination tool specific B10. The positions of the combination tool specific A9 and the combination tool specific B10 are staggered, and can slide up and down to adjust the position.

[0042] Specifically, the feeding and conveying mechanism 4 is designed to be placed on the left side of the machine tool 15. The fully automatic processing equipment is mainly composed of the following main mechanisms: the partition 14 is roughly located in the middle of the machine tool 15, and a through hole 13 is opened on the partition 14. The left side of the partition 14 is provided with a first power spindle 5, a positioning mechanism 6, a clamping and conveying mechanism 8, and a material drop bucket mechanism 16; the right side of the partition 14 is provided with a second power spindle 11, a combination to a specific A9, a combination knife specific B10, and a finished product discharge mechanism.

The telescopic push plate 24 pushes the semi-cotyledon parts 1 to be processed onto the feeding conveyor belt 21, and the conveyor belt motor 20 drives the feeding conveyor belt 21 to transmit to the part feeding port 25. The conveyor belt motor 20 is installed at one end of the feeding conveyor belt 21, and two photoelectric sensors 22 are installed in the entire stroke of the feeding conveyor belt 21, wherein the rear photoelectric sensor 22 is close to the conveying end position of the blocking cylinder 23, and the semi-cotyledon parts 1 to be processed are finally transferred to the feeding conveyor belt 21 through the recursive motion of the telescopic push plate 24. The blocking cylinder 23 is mainly used to pause the following parts. Specifically, when the current semi-embryo-cotyl part 1 to be processed is transmitted into the part feeding port 25, the following photoelectric sensor 22 detects the following part until the part is transmitted to the position of the blocking cylinder 23. The push rod of the blocking cylinder 23 extends out to block the following semi-embryo-cotyl part to be processed; after the previous semi-embryo-cotyl part to be processed is installed on the first power spindle 5, the push rod of the blocking cylinder 23 retracts, and the conveyor belt motor 20 continues to transmit, and transmits the following semi-embryo-cotyl part to be processed to the part feeding port 25.

The semi-embryo-cotyledon parts 1 to be processed are placed on the inclined raw material trough along a specific direction, and are pushed by the telescopic pusher plate 24 at the lowest position, gradually to the telescopic pusher plate 24 at the highest position, and finally the semi-embryo-cotyledon parts 1 to be processed are sent to the conveyor belt 21. The upper surface of the telescopic pusher plate 24 is preferably designed as an inclined surface.

[0045] like Figure 4c In the structure shown, two adjacent telescopic pushing plates 24 are provided with a fixed plate. When the rough embryonic shaft parts 1 to be processed are pushed by the lowest telescopic pushing plate and reach the same plane as the lowest fixed plate, the rough embryonic shaft parts 1 to be processed roll onto the lowest fixed plate, and then the three telescopic pushing plates 24 retract to their original positions. At this time, the rough embryonic shaft parts 1 to be processed roll from the lowest fixed plate to the second telescopic pushing plate, and then the three telescopic pushing plates 24 repeat the pushing action again. After three cycles, the rough embryonic shaft parts 1 to be processed can be sent to the conveyor belt 21.

The cylinder A35 on the bracket 36 drives the positioning rotary motor 34 to move up and down along the guide column 40. The claws on the positioning rotary motor 34 are used to grab the semi-cotyledon parts 1 to be processed.

[0050] The second baffle 29 is connected to one side of the positioning rotating motor 34.

[0054] The finished product discharging 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 deliver the finished shaft parts 3 into the receiving tray 12. An inclined surface is arranged at the upper end of the machine tool corresponding to the second power spindle 11 area, and the finished product falls into the inclined surface and falls into the finished product conveyor belt 18 after processing.

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

[0056] (1) The semi-cotyledon parts 1 to be processed are placed in a certain direction. Figure 4a-4b In the feeding and conveying mechanism 4, the material is transmitted to the conveyor belt 21 by the step-like transmission motion of the telescopic push plate 24. The conveyor belt 21 is driven by the conveyor belt motor 20 to convey the semi-embryo-cotyl parts 1 to be processed from one end of the conveyor belt to the other end. During the transmission, through the two photoelectric sensors 22, the material blocking cylinder 23 and the setting of the PLC program controller on the machine tool 1, a single semi-embryo-cotyl part 1 to be processed is transmitted to the end and put into the part feeding port 25;

[0057] (2) In the drop barrel mechanism 16, when the semi-embryo-cotyl part 1 to be processed rolls down from the part feeding port 25, its small shaft end faces downward and is initially blocked by the first baffle 27. The longitudinal telescopic cylinder 33 drives the first baffle 27 to perform telescopic movement, so that the semi-embryo-cotyl part 1 to be processed is separated from the part feeding port 25 and falls into the receiving cylinder 31. The second baffle 29 is used for protection when falling;

[0058] (3) When the semi-embryo-cotyl part 1 to be processed falls into the receiving cylinder 31, the positioning mechanism 6 starts to work, and the positioning rotary motor 3 is moved to the top of the receiving cylinder 31 through the cylinder B39, and the positioning rotary motor 34 is driven by the cylinder A35 to move downward until the claws on the positioning rotary motor 34 clamp the large shaft end of the semi-embryo-cotyl part 1 to be processed, and slowly rotate to make the inner square hole 2 of the small shaft end of the semi-embryo-cotyl 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 parts 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, away from the position where the blanking bucket mechanism 16 receives the material. Then, the blanking bucket mechanism 16, under the drive of the lateral displacement cylinder 26, moves the receiving cylinder 31 together with the semi-cotyloid part 1 to be processed therein to the side of the clamping and conveying mechanism. At this time, the clamping cylinder 41 is in a downward state, and the semi-cotyloid part 1 to be processed is clamped and grasped by the three-claw clamp 42. Take, then the cylinder C46 drives the mounting plate 44 together with the 90° rotating cylinder 43 and the clamping cylinder 41 to move up to a certain position, and then the 90° rotating cylinder 43 drives the clamping cylinder 41 to rotate 90°, so that the three-jaw clamp 42 together with the semi-molecular axis part 1 to be processed is in a horizontal state; the double-axis cylinder 50 starts to work and drives the entire clamping and conveying mechanism to move to a certain position together, so that the central axis of the semi-molecular axis part 1 to be processed clamped and grasped on the three-jaw clamp 42 is in a coincidence state 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-embryo-like part 1 to be processed under the drive of the screw pair 19, and the semi-embryo-like part 1 to be processed is clamped by the automatic clamping head on the first power spindle 5 and then retreats a certain distance; after the clamping and conveying mechanism returns to the initial position, the first power spindle 5 clamps the semi-embryo-like part 1 to be processed and moves together, and extends the semi-embryo-like part 1 to be processed through the through hole 13 opened on the machine tool partition 14 to reach the tool processing position of the combined tool body B10, and the combined tool body B10 is provided with a plurality of process tools, and the combined tool body B10 is for the first power spindle 5 The small shaft end of the semi-embryo-cotyl part 1 to be processed is processed one by one; until all the processing steps required for the small head end of the semi-embryo-cotyl part 1 to be processed are completed, the first power spindle 5 clamps and docks the semi-embryo-cotyl part 1 to be processed with the second power spindle 11 through the through hole 13 opened on the machine tool partition 14, and the second power spindle 11 coaxially and synchronously clamps the processed small shaft end of the semi-embryo-cotyl part 1 to be processed, and then the second power spindle 11 moves the large shaft end of the semi-embryo-cotyl part 1 to be processed to the position of the tool assembly A9, and all the required processing parts are processed in sequence according to the process;

[0061] (6) After the semi-mold embryonic shaft parts 1 to be processed are processed into finished shaft parts 3, the second power spindle 11 moves to the finished product conveyor belt 18 of the finished product discharging mechanism, releases the spindle clamp, and allows the formed shaft parts 3 to fall onto the finished product receiving conveyor belt 18 and be transferred to the final receiving tray 12.

[0062] The above-mentioned entire fully automatic processing equipment 15 realizes the integrated fully automatic processing process of shaft parts after feeding, and realizes a one-time forming processing technology under the condition of consistent coaxiality of the entire shaft parts. It greatly guarantees the overall accuracy of the parts, reduces manual operation, and simplifies the traditional processing technology that requires multiple machine tools to complete the processing. This embodiment realizes the fully automated processing process of shaft parts and improves the accuracy of shaft parts by integrating a fully automatic processing machine tool for shaft parts with multiple functional tools such as turning, milling, drilling, indexing, and coaxial reversing clamping.
