Description

Technical Field

[0001] The invention belongs to the technical field of chamfering machines, and in particular relates to a chamfering machine for machining mechanical parts. Background Art

[0002] A chamfering machine is a piece of equipment used in machining mechanical parts, primarily for chamfering the edges of metal or other materials. It removes sharp edges from the workpiece, creating a bevel at a specific angle, thereby smoothing the edge and reducing damage or scratches caused by sharp edges. Chamfering machines are commonly used in industries such as metalworking, mold manufacturing, and automotive parts processing, particularly where precise angles and efficient processing are required. The chamfer angle can often be adjusted to meet specific requirements, and some chamfering machines even support automated operation, improving production efficiency.

[0003] There are many different types of chamfering machines on the market. Although they can all complete chamfering processing, they still have certain defects. First of all, most of the existing chamfering machines are usually fixed-structured. Their feeding components and turning components are all fixed structures, so that the equipment can usually only complete the chamfering processing of one specification of bar. It cannot be quickly adapted to bars of different specifications and lengths, and its scope of application is relatively small. At the same time, the existing chamfering machines mostly use progressive feeding methods. Although they can also complete continuous automatic feeding and chamfering processing, in the actual working process, it will affect its overall processing efficiency to a certain extent. When processing large quantities of products, it will affect its overall processing progress. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the above-mentioned prior art and provide a chamfering machine for machining mechanical parts.

[0005] The technical solution adopted to solve the above technical problems is: a chamfering machine for machining mechanical parts, comprising a fixed frame, a feeding mechanism for conveying a metal shaft is fixedly installed at the rear end of the top of the fixed frame, and a sliding limit mechanism is fixedly installed at the center of the top of the fixed frame; A rotation limiting mechanism is fixedly installed at the top center of the sliding limiting mechanism, and a rotation feeding mechanism matching the rotation limiting mechanism is also fixedly installed on the top of the fixed frame, which is used to receive the metal shaft transmitted by the feeding mechanism and transmit the metal shaft to the turning chamfering position by rotating feeding. Two sets of symmetrically arranged guide limiting mechanisms are fixedly installed on the rotation feeding mechanism; Two sets of symmetrically arranged turning and chamfering mechanisms are slidably installed on both sides of the top of the sliding limit mechanism, which are used for automatically chamfering the two ends of the metal shaft. A servo drive mechanism for driving the two sets of turning and chamfering mechanisms is installed at the bottom of the sliding limit mechanism. A blanking guide frame matching the rotating feeding mechanism is fixedly connected to the front end of the top of the fixed frame; A controller for controlling the operation of the chamfering machine is installed on one side of the front end of the top of the fixed frame.

[0006] Furthermore, the fixed frame includes a fixed chassis, the bottom corners of the fixed chassis are fixedly connected to support legs, the bottom of the inner wall of the fixed chassis is fixedly connected to two symmetrically arranged limiting edge strips, and a waste collection box is placed between the two limiting edge strips.

[0007] Through the above technical solution, the fixed chassis mainly serves as the supporting structure of the chamfering machine, which is used to support and install components such as the feeding mechanism, sliding limit mechanism and rotary feeding mechanism. The waste collection box placed inside it can be used to collect metal debris generated during the turning and chamfering process.

[0008] Furthermore, the feeding mechanism includes a support plate fixed to the rear end of the top of the fixed frame, the top of the support plate is fixedly connected to two support columns, and the tops of the two support columns are fixedly connected to the feeding frame.

[0009] Through the above technical solution, the feeding mechanism is mainly used for automatic feeding of metal shafts. The metal shafts stacked on the feeding rack will automatically roll down under the action of gravity and enter the designated processing position and pushing position under the transmission of the rotating feeding mechanism. The feeding mechanism has a simple structure and is fixed to the top of the fixed frame by screws, so that it can be quickly replaced to process feeding racks of different sizes, thereby completing the processing of metal shafts of different specifications.

[0010] Furthermore, the sliding limiting mechanism includes a limiting slide fixed to the top of the fixed frame, limiting slide grooves are opened on both sides of the top of the limiting slide, limiting holes and blanking holes are opened at the bottom of the two limiting slide grooves respectively, and an installation hole is opened in the middle of the limiting slide.

[0011] Through the above technical solution, the sliding limit mechanism serves as both a supporting structure and a limiting structure. It is mainly used for sliding guidance and limiting of the turning and chamfering mechanism to ensure that the two sets of turning and chamfering mechanisms can move accurately, thereby ensuring the chamfering accuracy; at the same time, a blanking hole is opened at the bottom of the limiting slide, and metal debris generated during the turning and chamfering process can fall into the fixed chassis through the blanking hole and be collected in the waste collection box.

[0012] Furthermore, the rotation limiting mechanism includes a mounting seat fixed at the top center of the sliding limiting mechanism, the rear end of the top of the mounting seat is fixedly connected to the limiting frame, a shrinkage groove is opened at the top center of the mounting seat, a fixed clamping block is arranged in the shrinkage groove, and a clamping cylinder for driving the fixed clamping block to rise and fall is fixedly installed at the bottom center of the mounting seat.

[0013] Through the above technical scheme, the rotary limiting mechanism is mainly used to cooperate with the rotary feeding mechanism. During the rotary feeding process, the rotary feeding mechanism can cooperate with the mounting seat and the limiting frame on its top to limit the metal shaft during the transmission process, so as to ensure that the rotary feeding mechanism can transmit the metal shaft to the position, thereby completing continuous chamfering and pushing operations; in addition, a clamping cylinder is fixedly installed at the bottom center of the mounting seat. When the metal shaft rotates to the processing position, the piston rod of the clamping cylinder will quickly drive the fixed clamp block to move upward, thereby cooperating with the feeding plate of the rotary feeding mechanism to complete the stable clamping and fixation of the metal shaft in the processing position to prevent it from shaking or displacement during the subsequent chamfering process. When the chamfering is completed, the clamping cylinder will drive the fixed clamp block to automatically reset.

[0014] Furthermore, the rotary feeding mechanism includes a fixed bracket fixed to the top rear end of the fixed frame, the front end of the fixed bracket is rotatably connected to a rotating shaft, and the rotating shaft is respectively sleeved with a left feed tray and a right feed tray, and the left feed tray and the right feed tray are provided with a plurality of evenly distributed positioning slots, the outer sides of the left feed tray and the right feed tray are fixedly connected with a positioning shaft sleeve, and the inner sides of the left feed tray and the right feed tray are respectively fixedly connected with a first limit sleeve and a second limit sleeve that are sleeved with each other, and the first limit sleeve and the second limit sleeve are locked and fixed by a fixing screw, and one end of the rotating shaft is fixedly installed with a first transmission wheel, and a first servo motor is also installed on the fixed bracket, and a first drive wheel is fixedly installed on the output shaft of the first servo motor, and a transmission belt is installed between the first drive wheel and the first transmission wheel.

[0015] Through the above technical solution, when the rotary feeding mechanism is working, the left feeding tray and the right feeding tray are mainly driven by the first servo motor to rotate. First, the metal shaft to be processed will automatically roll into a set of positioning slots at the loading position under the transmission of the feeding mechanism, and then the metal shaft will move along a fixed rotation direction under the synchronous drive of the left feeding tray and the right feeding tray, and then it will be accurately transmitted to the chamfering processing position. After the chamfering processing is completed, the left feeding tray and the right feeding tray will continue to drive it to move until it moves to the unloading position. At this time, the metal shaft after chamfering will automatically fall onto the unloading guide frame under the action of gravity, thereby realizing the centralized collection of the metal shafts; in addition, the movement of the left feeding tray and the right feeding tray is driven by the first servo motor. The motor is controlled to make the transmission, processing pause and transmission and unloading processes smoother, which not only shortens the processing pause time, but also improves the overall processing efficiency; more importantly, the distance between the left feed tray and the right feed tray can be freely adjusted within a certain range. Since the inner sides of the left feed tray and the right feed tray are respectively fixedly connected with a first limit clamping sleeve and a second limit clamping sleeve that are mutually sleeved, after the spacing adjustment is completed, they can be locked and fixed by fixing screws. At the same time, for metal shafts of different diameters, different left feed trays and right feed trays can also be quickly replaced, so that the positioning slots can adapt to the corresponding metal shafts, making its overall scope of application wider, and it can be suitable for chamfering processing of metal shafts of different diameters and lengths.

[0016] Furthermore, the two positioning sleeves are fixed to the rotating shaft by screws.

[0017] Through the above technical solution, the left feeding tray and the right feeding tray can be fixed to the rotating shaft, and then can be rotated under the drive of the transmission belt, thereby completing precise servo feeding work.

[0018] Furthermore, the guide limiting mechanism includes a limiting plate, one side of which is fixedly connected to two threaded columns passing through the fixed bracket, and each of the threaded columns is threadedly connected to two locking nuts for locking the limiting plate.

[0019] Through the above technical solution, the guide and limit mechanism is mainly used to align the two ends of the metal shaft during the transmission process. Under the guide and limit action of the limit plates on both sides, when the metal shaft moves to the processing position, its two ends are symmetrically arranged, thereby ensuring the subsequent processing accuracy and processing quality. In addition, the position of the limit plate can be freely adjusted within a certain range through two sets of locking nuts, so that it can adapt to the guide limit of metal shafts of different lengths.

[0020] Furthermore, the turning and chamfering mechanism includes a movable slide slidably connected to the limiting slide groove, a ball nut seat is provided at the bottom center of the movable slide, a rotating shaft is rotatably connected in the movable slide, one end of the rotating shaft is fixedly connected to the rotating tool holder, a turning tool is fixedly mounted on the rotating tool holder, a second transmission wheel is fixedly mounted on the other end of the rotating shaft, a driving motor is fixedly mounted on the top of the movable slide, a second driving wheel is fixedly mounted on the output end of the driving motor, and a synchronous belt is installed between the second driving wheel and the second transmission wheel.

[0021] Through the above technical solution, the turning and chamfering mechanism serves as the main execution structure, which is mainly used for turning processing at both ends of the metal shaft during operation. During operation, the driving motor drives the synchronous belt through the second driving wheel to operate, and then drives the second transmission wheel and the rotating shaft to rotate at high speed. At the same time, the servo drive mechanism can simultaneously drive the two sets of turning and chamfering mechanisms to approach the metal shaft synchronously. Since a turning tool is installed on the rotating tool holder at the end of the rotating shaft, the turning tool can complete the chamfering processing of the metal shaft during high-speed rotation and linear feed; further, the two sets of turning and chamfering mechanisms can be installed at the same time, or only one set can be installed, so that the chamfering processing of one end or both ends of the metal shaft can be completed according to actual conditions.

[0022] Furthermore, the servo drive mechanism includes a first bearing seat and a second bearing seat fixed at both ends of the bottom of the limiting slide, a bidirectional ball screw is installed between the first bearing seat and the second bearing seat, the two ball nut seats are respectively sleeved on both sides of the bidirectional ball screw, and a second servo motor for driving the bidirectional ball screw to rotate is installed on the outer side of the second bearing seat, and two symmetrically arranged waste sleeves are fixedly connected to the bidirectional ball screw.

[0023] Through the above technical solution, the servo drive mechanism is mainly used for feeding and retracting the two sets of turning and chamfering mechanisms during the chamfering process. During operation, the second servo motor drives the bidirectional ball screw to rotate synchronously. The bidirectional ball screw has symmetrically arranged bidirectional threads, so that during the rotation process, it can drive the two sets of turning and chamfering mechanisms to approach or move away from the metal shaft at the same time, which not only ensures the synchronization of movement, but also ensures the processing accuracy.

[0024] The beneficial effects of the present invention are as follows: (1) The present invention designs a simple rotary feeding mechanism, and the movement of the left feeding tray and the right feeding tray is controlled by the first servo motor, so that the transmission, processing pause and transmission and unloading processes are smoother, which not only shortens the processing pause time, but also improves the overall processing efficiency; (2) The spacing between the left feeding tray and the right feeding tray of the present invention can be freely adjusted within a certain range. At the same time, for metal shafts of different diameters, different left feeding trays and right feeding trays can be quickly replaced, so that the positioning slots can adapt to the corresponding metal shafts, making its overall application range wider and applicable to the chamfering processing of metal shafts of different diameters and lengths; (3) The present invention designs a symmetrically arranged turning and chamfering mechanism, and the two sets of turning and chamfering mechanisms can be installed at the same time, or only one set can be installed, so that the chamfering processing of one end or both ends of the metal shaft can be completed according to actual conditions.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0028] like Figures 1-17As shown, a chamfering machine for machining mechanical parts in this embodiment includes a fixed frame 1, and the fixed frame 1 includes a fixed chassis 101. Support legs 102 are fixedly connected to the bottom corners of the fixed chassis 101. Two symmetrically arranged limiting side strips 103 are fixedly connected to the bottom of the inner wall of the fixed chassis 101. A waste collection box 104 is placed between the two limiting side strips 103. The fixed chassis 101 mainly serves as a supporting structure of the chamfering machine, which is used to support and install components such as the feeding mechanism 2, the sliding limiting mechanism 3 and the rotating feeding mechanism 5. The waste collection box 104 placed inside it can be used to collect metal debris generated during the turning and chamfering process.

[0029] Regarding the feeding mechanism 2, refer to Figure 1-Figure 5 , a feeding mechanism 2 for conveying the metal shaft 11 is fixedly installed at the top rear end of the fixed frame 1, and the feeding mechanism 2 includes a support plate 201 fixed to the top rear end of the fixed frame 1, and two support columns 202 are fixedly connected to the top of the support plate 201, and a feeding rack 203 is fixedly connected to the top of the two support columns 202. The feeding mechanism 2 is mainly used for automatic feeding of the metal shaft 11. The metal shaft 11 stacked on the feeding rack 203 will automatically roll down under the action of gravity, and enter the designated processing position and pushing position under the transmission of the rotating feeding mechanism 5. The feeding mechanism 2 has a simple structure and is fixed to the top of the fixed frame 1 by screws, so that it can be quickly replaced to process feeding racks 203 of different sizes, thereby completing the processing of metal shafts 11 of different specifications.

[0030] Regarding the sliding limit mechanism 3, refer to Figure 6-Figure 9 The top center of the fixed frame 1 is fixedly installed with a sliding limit mechanism 3; the sliding limit mechanism 3 includes a limit slide 301 fixed to the top of the fixed frame 1, and limit slide grooves 302 are provided on both sides of the top of the limit slide 301, and the bottoms of the two limit slide grooves 302 are respectively provided with limit holes 303 and blanking holes 304, and a mounting hole 305 is provided in the middle of the limit slide 301. The sliding limit mechanism 3 serves as both a supporting structure and a limiting structure. It is mainly used for sliding guidance and limiting of the turning and chamfering mechanism 7 to ensure that the two sets of turning and chamfering mechanisms 7 can move accurately, thereby ensuring the chamfering accuracy; at the same time, a blanking hole 304 is provided at the bottom of the limit slide 302, and metal debris generated during the turning and chamfering process can fall into the fixed chassis 101 through the blanking hole 304 and be collected in the waste collection box 104.

[0031] Regarding the rotation limiting mechanism 4, refer to Figure 10-13A rotation limiting mechanism 4 is fixedly installed at the top center of the sliding limiting mechanism 3. The rotation limiting mechanism 4 includes a mounting seat 401 fixed to the top center of the sliding limiting mechanism 3. The rear end of the top of the mounting seat 401 is fixedly connected to the limiting frame 402. A contraction groove 403 is provided at the top center of the mounting seat 401. A fixed clamping block 404 is provided in the contraction groove 403. A clamping cylinder 405 for driving the fixed clamping block 404 to rise and fall is fixedly installed at the bottom center of the mounting seat 401. The rotation limiting mechanism 4 is mainly used to cooperate with the rotary feeding mechanism 5. During the rotary feeding process, the rotary feeding mechanism 5 can cooperate with the mounting seat 401 and the limiting frame 402 on its top to realize the limitation of the metal shaft 11 during the transmission process, so as to ensure that the rotary feeding mechanism 5 can transmit the metal shaft 11 into place, thereby completing continuous chamfering and pushing operations.

[0032] Furthermore, in this embodiment, a clamping cylinder 405 is fixedly installed at the bottom center of the mounting seat 401. When the metal shaft 11 rotates to the processing position, the piston rod of the clamping cylinder 405 will quickly drive the fixed clamping block 404 to move upward, thereby cooperating with the feeding plate of the rotating feeding mechanism 5 to complete the stable clamping and fixing of the metal shaft 11 at the processing position to prevent it from shaking or displacement during the subsequent chamfering process. When the chamfering is completed, the clamping cylinder 405 will drive the fixed clamping block 404 to automatically reset.

[0033] Regarding the rotary feeding mechanism 5, refer to Figure 11-14, a rotary feeding mechanism 5 matching the rotary limiting mechanism 4 is also fixedly installed on the top of the fixed frame 1, which is used to receive the metal shaft 11 transmitted by the feeding mechanism 2 and transmit the metal shaft 11 to the turning chamfering position by rotating feeding. The rotary feeding mechanism 5 includes a fixed bracket 501 fixed to the rear end of the top of the fixed frame 1, and the front end of the fixed bracket 501 is rotatably connected to the rotating shaft 502, and the rotating shaft 502 is respectively sleeved with a left feeding tray 503 and a right feeding tray 504, and the left feeding tray 503 is connected to the right feeding tray 504. The left and right feeding trays 503 and 504 are provided with a plurality of evenly distributed positioning slots 505, the outer sides of the left feeding tray 503 and the right feeding tray 504 are fixedly connected with positioning sleeves 506, the inner sides of the left feeding tray 503 and the right feeding tray 504 are respectively fixedly connected with a first limiting sleeve 507 and a second limiting sleeve 508 which are sleeved with each other, the first limiting sleeve 507 and the second limiting sleeve 508 are locked and fixed by fixing screws 509, and one end of the rotating shaft 502 is fixedly installed with a first transmission sleeve The first servo motor 511 is also installed on the fixed bracket 501, and the first driving wheel 512 is fixedly installed on the output shaft of the first servo motor 511. A transmission belt 513 is installed between the first driving wheel 512 and the first transmission wheel 510. When the rotary feeding mechanism 5 is working, the left feeding tray 503 and the right feeding tray 504 are mainly driven by the first servo motor 511 to rotate. First, the metal shaft 11 to be processed will automatically roll to a set of fixed positions at the loading position under the transmission of the feeding mechanism 2. The metal shaft 11 is positioned in the card slot 505, and then the metal shaft 11 will move along a fixed rotation direction under the synchronous drive of the left feed tray 503 and the right feed tray 504, and then be accurately transferred to the chamfering processing position. After the chamfering processing is completed, the left feed tray 503 and the right feed tray 504 will continue to drive it to move until it moves to the material return position. At this time, the metal shaft 11 after chamfering will automatically fall onto the unloading guide frame 9 under the action of gravity, thereby realizing the centralized collection of the metal shaft 11.

[0034] Furthermore, in this embodiment, the movement of the left feed tray 503 and the right feed tray 504 is controlled by the first servo motor 511, making the transmission, processing pause and transmission and unloading processes smoother, which not only shortens the processing pause time, but also improves the overall processing efficiency.

[0035] Furthermore, and more importantly, the present embodiment is that the spacing between the left feed tray 503 and the right feed tray 504 can be freely adjusted within a certain range. Since the inner sides of the left feed tray 503 and the right feed tray 504 are respectively fixedly connected with a first limiting sleeve 507 and a second limiting sleeve 508 which are mutually sleeved, after the spacing adjustment is completed, they can be locked and fixed by fixing screws 509. At the same time, for metal shafts 11 of different diameters, different left feed trays 503 and right feed trays 504 can also be quickly replaced, so that the positioning slots 505 can adapt to the corresponding metal shafts 11, making its overall scope of application wider, and it can be applicable to chamfering processing of metal shafts 11 of different diameters and lengths.

[0036] Furthermore, in this embodiment, the two positioning sleeves 506 are fixed to the rotating shaft 502 by screws, so that the left feed tray 503 and the right feed tray 504 can be fixed to the rotating shaft 502, and then can rotate under the drive of the transmission belt 513, thereby completing precise servo feeding.

[0037] Regarding the guide limit mechanism 6, refer to Figure 15 Two sets of symmetrically arranged guide and limit mechanisms 6 are fixedly installed on the rotating feeding mechanism 5; the guide and limit mechanism 6 includes a limit plate 601, one side of the limit plate 601 is fixedly connected to two threaded columns 602 that pass through the fixed bracket 501, and each threaded column 602 is threadedly connected to two locking nuts 603 for locking the limit plate 601. The guide and limit mechanism 6 is mainly used for aligning the two ends of the metal shaft 11 during the transmission process. Under the guiding and limiting action of the limit plates 601 on both sides, when the metal shaft 11 moves to the processing position, its two ends are symmetrically arranged, thereby ensuring the subsequent processing accuracy and processing quality. In addition, the position of the limit plate 601 can be freely adjusted within a certain range by two sets of locking nuts 603, so that it can adapt to the guide limit of metal shafts 11 of different lengths.

[0038] For turning chamfering mechanism 7, refer to Figure 16-17Two sets of symmetrically arranged turning and chamfering mechanisms 7 are slidably installed on both sides of the top of the sliding limit mechanism 3, which are used for automatic chamfering of the two ends of the metal shaft 11. The turning and chamfering mechanism 7 includes a movable slide 701 slidably connected to the limiting slide groove 302, and a ball nut seat 702 is provided at the bottom center of the movable slide 701. A rotating shaft 703 is rotatably connected to the movable slide 701, and one end of the rotating shaft 703 is fixedly connected to a rotating tool holder 704. A turning tool 705 is fixedly installed on the rotating tool holder 704, and a second transmission wheel 706 is fixedly installed on the other end of the rotating shaft 703. A driving motor 707 is fixedly installed on the top of the movable slide 701, and a second driving wheel 708 is fixedly installed on the output end of the driving motor 707. A synchronous belt 709 is installed between the second driving wheel 708 and the second transmission wheel 706. The turning and chamfering mechanism 7 serves as the main execution structure. During operation, it is mainly used for turning processing at both ends of the metal shaft 11. During operation, the driving motor 707 drives the synchronous belt 709 to operate through the second driving wheel 708, thereby driving the second transmission wheel 706 and the rotating shaft 703 to rotate at high speed. At the same time, the servo drive mechanism 8 can simultaneously drive the two sets of turning and chamfering mechanisms 7 to approach the metal shaft 11 synchronously. Since a turning tool 705 is installed on the rotating tool holder 704 at the end of the rotating shaft 703, the turning tool 705 can complete the chamfering processing of the metal shaft 11 during high-speed rotation and linear feed.

[0039] Furthermore, in this embodiment, the two groups of turning and chamfering mechanisms 7 can be installed simultaneously, or only one group can be installed, so that the chamfering processing of one end or both ends of the metal shaft 11 can be completed according to actual conditions.

[0040] Regarding the servo drive mechanism 8, refer to Figure 1-Figure 5 The bottom of the sliding limit mechanism 3 is equipped with a servo drive mechanism 8 for driving two sets of turning and chamfering mechanisms 7. The servo drive mechanism 8 includes a first bearing seat 801 and a second bearing seat 802 fixed at both ends of the bottom of the limit slide 301. A bidirectional ball screw 804 is installed between the first bearing seat 801 and the second bearing seat 802. The two ball nut seats 702 are respectively sleeved on both sides of the bidirectional ball screw 804. A second servo motor 8 is installed on the outer side of the second bearing seat 802 for driving the bidirectional ball screw 804 to rotate. 03. Two symmetrically arranged waste sleeves 805 are fixedly connected to the bidirectional ball screw 804. The servo drive mechanism 8 is mainly used for feeding and retracting the two sets of turning and chamfering mechanisms 7 during the chamfering process. When working, the second servo motor 803 drives the bidirectional ball screw 804 to rotate synchronously. The bidirectional ball screw 804 has symmetrically arranged bidirectional threads, so that it can drive the two sets of turning and chamfering mechanisms 7 to approach or move away from the metal shaft 11 at the same time during the rotation process, which not only ensures the synchronization of movement, but also ensures the processing accuracy.

[0041] Furthermore, in this embodiment, two symmetrically arranged waste blocking sleeves 805 are fixedly connected to the bidirectional ball screw 804. The arrangement of the waste blocking sleeves 805 can prevent fallen metal debris from entering the threaded portion of the screw, thereby ensuring the stability and processing accuracy of the servo drive mechanism 8.

[0042] Furthermore, in this embodiment, a material discharge guide frame 9 matching the rotating feeding mechanism 5 is fixedly connected to the top front end of the fixed frame 1. After processing, the metal shaft 11 will automatically fall onto the material discharge guide frame 9 under the action of gravity, thereby realizing the centralized collection of the metal shaft 11.

[0043] Furthermore, in this embodiment, a controller 10 for controlling the operation of the chamfering machine is installed on one side of the top front end of the fixed frame 1. The input end of the controller 10 is electrically controlled by the output end of each actuator through a connection guide, so that the operator can adjust the parameters of the chamfering machine through the controller 10 for integrated control.

[0044] The working principle of this embodiment is as follows: during operation, the metal shafts 11 stacked on the feed rack 203 will automatically roll down under the action of gravity. At this time, the metal shafts 11 to be processed will automatically roll down to a set of positioning slots 505 at the loading position under the transmission of the feeding mechanism 2. Subsequently, the metal shafts 11 will move along a fixed rotation direction under the synchronous drive of the left feeding tray 503 and the right feeding tray 504, and then be accurately transmitted to the chamfering processing position; At the same time, the driving motor 707 drives the synchronous belt 709 through the second driving wheel 708 to rotate, thereby driving the second transmission wheel 706 and the rotating shaft 703 to rotate at high speed, and the servo drive mechanism 8 can simultaneously drive the two sets of turning and chamfering mechanisms 7 to synchronously approach the metal shaft 11. Since a turning tool 705 is installed on the rotating tool holder 704 at the end of the rotating shaft 703, the turning tool 705 can complete the chamfering process of the metal shaft 11 during the high-speed rotation and linear feed process; After the chamfering process is completed, the left feed tray 503 and the right feed tray 504 will continue to drive it to move until it moves to the material return position. At this time, the metal shaft 11 after chamfering will automatically fall onto the unloading guide frame 9 under the action of gravity, thereby realizing the centralized collection of the metal shaft 11.
