Description

Technical Field

[0001] This invention relates to the field of metal shaft machining, and in particular, to an automated machining equipment for double-end faces of metal shafts. Background Technology

[0002] In the field of machining, machining both ends of metal shaft parts is a very common core process. With the continuous upgrading of modern manufacturing towards mass production and automation, enterprises are placing higher demands on the continuous operation capability and overall production efficiency of machining equipment. To ensure the machining speed at both ends of metal shafts, the industry currently typically uses dual-head machining centers to complete this type of operation.

[0003] Chinese utility model patent CN206286589U discloses a horizontal double-head drilling machine. The machine mainly includes a bed and a headstock, with a clamping device mounted on the bed for holding the workpiece. Its working principle involves a motor on the headstock driving the multi-head drill to rotate, which in turn drives the multi-axis power head and drill bit at the front end of the multi-head drill to perform cutting.

[0004] However, the equipment's clamping system only solves the problem of fixing the workpiece during processing, but it is not equipped with an automatic loading and unloading mechanism linked to it. The insertion, alignment, and removal of the metal shaft after processing all require frequent manual intervention. This highly manual loading and unloading method not only increases the labor intensity and safety hazards for workers, but also results in a low overall level of automation for the equipment, making it difficult to meet the current demand for efficient, unmanned, and continuous production. Summary of the Invention

[0005] In view of this, the purpose of this invention is to provide an automated processing equipment for double-end faces of metal shafts, which solves the technical problem that existing double-head processing machines rely heavily on manual operation in the loading and unloading process, resulting in high labor intensity for workers and low overall automated continuous production efficiency of the equipment.

[0006] To solve the above-mentioned technical problems, the technical solution of the present invention is: an automated machining equipment for double-end faces of metal shafts, comprising a frame, a support seat slidably connected to the frame along its transverse direction, a tool holder slidably connected to the support seat, the tool holder moving longitudinally along the frame, a tool connected to the tool holder, a storage box and a support frame provided on the frame, a guide groove provided on the frame, a first power component provided on the frame, a first power shaft of the first power component extending out and causing the metal shaft to fall into the guide groove through a transmission mechanism, a second power component provided on the support frame, a third power component connected to the second power shaft of the second power component, a rotating component connected to the third power shaft of the third power component, and the third power component via a third... A power shaft drives a rotating component to rotate 180 degrees. A second power component drives a third power component to move. The rotating component has a placement hole. A seventh power component is provided on the frame for pushing a metal shaft into the placement hole along a guide groove. The placement hole is used to receive a metal shaft moving along the length of the guide groove. A fourth power component is connected to the outer wall of the third power component and / or the second power shaft. The fourth power shaft of the fourth power component corresponds to the placement hole. The frame is driven and rotatably connected to a gripper by a power mechanism. The fourth power shaft passes through the placement hole and pushes the metal shaft into the gripper for clamping. A fifth power component is provided on the frame. The fifth power shaft of the fifth power component passes through the gripper to push the metal shaft into the placement hole or for unloading.

[0007] To achieve the above technical solution, the first power shaft of the first power component extends, driving the transmission mechanism to move and transfer the metal shaft in the storage box into the guide groove, where it slides down. Simultaneously, the second power component activates, driving the third power component with a rotating component to move to the end of the guide groove, so that the placement hole on the rotating component receives the metal shaft. Next, the second power component drives the third power component, along with the metal shaft, to move in front of the gripper. The fourth power component on the outer wall of the third power component activates, its fourth power shaft extending to push the metal shaft from the placement hole into the gripper. The power mechanism drives the gripper to clamp and rotate the metal shaft for end-face processing. After processing, the gripper releases, and the fifth power shaft of the fifth power component extends, passing through the gripper's interior, pushing the metal shaft from the gripper into the placement hole or directly ejecting it for unloading. This achieves fully automated operation, effectively reducing the labor intensity of manual intervention and improving the equipment's continuous operation capability and overall production efficiency.

[0008] In a preferred embodiment of the present invention, the transmission mechanism includes a pusher plate, a transmission plate, and a limiting plate. The limiting plate has a limiting groove along the height direction of the frame. The pusher plate is slidably connected in the limiting groove. The pusher plate is connected to a first power shaft. The upper end of the pusher plate has an inclined bearing surface for receiving a metal shaft. The transmission plate is connected to the frame. After the pusher plate pushes the metal shaft past the limiting plate, the metal shaft falls into the guide groove along the transmission plate. The bottom wall of the storage box has a transmission ramp that slopes towards the limiting plate.

[0009] To achieve the above technical solution, the metal shafts inside the storage box automatically roll down the inclined guide surface on the bottom wall under gravity and gather towards the pusher plate. The first power shaft drives the pusher plate to slide upward along the limiting groove on the limiting plate, and the inclined bearing surface at the upper end of the pusher plate supports a single metal shaft. As the pusher plate continues to rise and passes the top edge of the limiting plate, the lifted metal shafts fall into the guide groove along the guide plate under gravity. The mechanical reciprocating lifting mechanism achieves automatic gathering, individual separation, and precise feeding of the metal shafts, reducing the probability of multiple metal shafts jamming and ensuring the continuity of the machine's feeding process.

[0010] In a preferred embodiment of the present invention, the power mechanism includes a power motor, a power wheel, and a gear ring. A support tube is slidably connected to the frame along its length. The gear ring is fixed to the outer wall of the support tube. The power motor is fixed to the frame and is used to drive the power wheel to rotate. The power wheel meshes with the gear ring. A sixth power component is connected to the frame. The sixth power shaft of the sixth power component is connected to the support tube through a connecting mechanism. The support tube moves away from the tool holder and clamps the metal shaft with a gripper through a linkage mechanism. The support tube moves towards the tool holder and separates the gripper from the metal shaft through the linkage mechanism. The fifth power shaft passes through the support tube.

[0011] To achieve the above technical solution, the power motor drives the power wheel to rotate after being powered on. The power wheel, through meshing with the toothed ring on the outer wall of the support tube, drives the support tube to rotate at high speed in the circumferential direction on the frame. When the support tube is rotating or stationary, the sixth power shaft of the sixth power component pulls or pushes the support tube through a connecting mechanism, causing it to reciprocate axially along the length of the frame. When the support tube moves away from the tool holder, the linkage mechanism is activated to cause the gripper to retract and clamp the metal shaft. When the support tube moves closer to the tool holder, the linkage mechanism is activated to cause the gripper to release and separate from the metal shaft. During this process, the fifth power shaft remains inside the support tube. The circumferential rotation of the support tube, the axial reciprocating clamping motion, and the internal through-feedback motion of the fifth power shaft are highly integrated in the spatial layout, ensuring that the actions of each component do not interfere with each other, thus improving the reliability of the equipment under complex operating conditions.

[0012] In a preferred embodiment of the present invention, the linkage mechanism includes a first inclined surface, a second inclined surface, a first elastic element, a positioning disk, a positioning sleeve, a sliding groove, and a slider. The gripper includes multiple clamping plates. The positioning disk is fixed to the outer wall of the support tube. The positioning sleeve is rotatably connected to the frame and slidably connected to the gripper. The sliding groove is formed on the positioning disk and extends towards the axis near the support tube. The slider is slidably connected to the sliding groove and is connected to the clamping plate. The two ends of the first elastic element are respectively connected to the slider and the positioning disk. The first inclined surface is formed on the positioning sleeve, and the second inclined surface is formed on the clamping plate. The first inclined surface and the second inclined surface are in contact.

[0013] To achieve the above technical solution, when the support tube moves axially under the drive of the sixth power component, the positioning disc fixed on the outer wall of the support tube, as well as the slider and clamping plate slidably connected to the slide groove, undergo synchronous axial displacement. During this process, the second inclined surface on the clamping plate is forced to slide and compress relative to the first inclined surface. The physical compression of the first inclined surface against the second inclined surface forces the clamping plate, along with the slider, to move along the slide groove towards the axis of the support tube, overcoming the elastic force of the first elastic component and achieving radial clamping of the metal shaft. When the axial thrust is removed in the opposite direction, the first elastic component releases its elastic force, pulling the slider back to its original position, and the clamping plate expands outward to loosen. By accurately converting the axial linear motion of the power component into the radial clamping motion of the clamping plate, rapid, multi-point centered clamping of the metal shaft is achieved, improving the accuracy of machining positioning.

[0014] In a preferred embodiment of the present invention, the connecting mechanism includes a left positioning ring and a right positioning ring, a positioning cavity is formed between the left positioning ring and the right positioning ring, a fixing ring is connected to the outer wall of the support tube, the fixing ring is located in the positioning cavity, and the left positioning ring and / or the right positioning ring is connected to the sixth power shaft.

[0015] To achieve the above technical solution, the pushing and pulling force of the sixth power shaft is directly applied to the left positioning ring and / or the right positioning ring; when the support tube rotates at high speed, the fixed ring connected to its outer wall rotates synchronously inside the positioning cavity formed by the left and right positioning rings; when the sixth power shaft moves back and forth, the inner side wall of the left or right positioning ring will abut against the side of the fixed ring, thereby transmitting the axial displacement force to the support tube.

[0016] As a preferred embodiment of the present invention, a connecting groove is provided on the inner wall of the placement hole, and a pressure roller is provided in the connecting groove. After the seventh power shaft of the seventh power component pushes the metal shaft into the placement hole, a displacement mechanism is used to place a part of the pressure roller in the placement hole. The outer wall of the metal shaft is used to abut against the outer wall of the pressure roller.

[0017] To achieve the above technical solution, during the process of the seventh power shaft pushing the metal shaft into the placement hole, the feeding action of the seventh power shaft synchronously triggers the displacement mechanism. The displacement mechanism drives the pressure roller, which was originally hidden in the connecting groove on the inner wall of the placement hole, to generate radial displacement towards the central axis of the placement hole. At least a portion of the pressure roller then protrudes into the placement hole, causing the outer wall of the pressure roller to tightly press against the outer wall of the metal shaft, thus mechanically pressing or rolling out the corresponding marks on the outer surface of the metal shaft. The metal shaft surface marking process is integrated into the loading and transfer action, completing surface marking simultaneously with the metal shaft being pushed into the placement hole. This eliminates the need for a separate subsequent marking station and equipment investment, improving production integration.

[0018] In a preferred embodiment of the present invention, the displacement mechanism includes a second elastic element, a third elastic element, a contact block, a slide rod, and a third inclined surface. The slide rod is slidably connected to the rotating component along the axial direction of the placement hole. The third inclined surface is formed at the end of the slide rod. The contact block is connected to the seventh power shaft and is used to push the slide rod to move. The two ends of the second elastic element are respectively connected to the slide rod and the rotating component. A straight groove is formed on the rotating component. A displacement block is slidably connected in the straight groove. A displacement shaft is fixedly connected to the displacement block. The third inclined surface is used to abut against the outer wall of the displacement shaft. The pressure roller is rotatably connected to the displacement shaft. The two ends of the third elastic element are respectively connected to the inner wall of the straight groove and the displacement block.

[0019] To achieve the above technical solution, when the seventh power shaft moves forward, the abutment block pushes the slide bar to overcome the resistance of the second elastic element and slide along the axial direction of the placement hole. The third inclined surface at the end of the slide bar then presses against the displacement shaft, forcing the displacement block to overcome the resistance of the third elastic element and slide within the straight groove, thus first placing a portion of the pressure roller into the placement hole. As the seventh power shaft continues to move forward, the displacement shaft passes over the third inclined surface and slides into contact with the outer wall of the slide bar, while the radial position of the pressure roller remains fixed. Subsequently, under the continuous pushing of the seventh power shaft, the metal shaft that has entered the placement hole continues to move, and the outer wall of the metal shaft rolls and presses against the outer wall of the pressure roller, which remains in a fixed protruding state, thus pressing an imprint onto the surface of the metal shaft. When the seventh power shaft completes its push-in and retraction, the abutment block retracts, and the second and third elastic elements release their elastic force to push the slide bar and displacement block back to their original positions. The pressure roller then exits the placement hole, while the metal shaft remains inside. This purely mechanical control structure eliminates the need for complex sensors or independent marking power sources, greatly improving the continuity of the marking action and the overall operational stability of the system.

[0020] As a preferred embodiment of the present invention, a positioning groove is provided on the inner wall of the placement hole, and a spring piece for abutting against the outer wall of the metal shaft is provided in the positioning groove. The spring piece is U-shaped and its two ends are connected to the inner wall of the positioning groove, and the middle part of the spring piece is located in the placement hole.

[0021] To achieve the above technical solution, during the process of the seventh power shaft pushing the metal shaft into the placement hole, before the metal shaft contacts the pressure roller, its outer wall preferentially contacts the middle of the spring plate protruding inside the placement hole; the metal shaft squeezes the spring plate, causing it to undergo elastic deformation; during the subsequent rotation of the metal shaft driven by the rotating component, the spring plate generates a deformation rebound force, continuously abutting against the outer wall of the metal shaft remaining in the placement hole, thus radially limiting the metal shaft. When the rotating component rotates at high speed, the continuous frictional holding force provided by the spring plate can effectively prevent the metal shaft from being thrown out of the placement hole due to rotational centrifugal force.

[0022] As a preferred embodiment of the present invention, the tool holder is connected to an inclined feeding plate, which is used to receive the metal shaft being fed from the gripper.

[0023] To achieve the above technical solution, when the processed metal shaft is pushed away from the gripper by the fifth power shaft and falls due to gravity, the unloading plate accurately catches the falling metal shaft. The metal shaft automatically rolls down the inclined guide surface of the unloading plate to the unified collection area below. This realizes the automatic diversion of finished products, optimizes the automated collection and export process of processed finished products, and reduces the labor intensity of manual collection.

Detailed Implementation

[0026] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, so that the technical solution of the present invention can be more easily understood and mastered.

[0027] An automated machining equipment for double-end faces of metal shafts includes a frame 1. A support base 2 is slidably connected to the frame 1 along its transverse direction. A tool holder 3, which moves longitudinally along the frame 1, is slidably connected to the support base 2. A cutting tool 4 for cutting, drilling, or chamfering is fixedly connected to the tool holder 3 by bolts or tool clamps. The support base 2 and the tool holder 3 are moved by a servo motor in conjunction with a screw and a guide rod.

[0028] The movement of the support base 2 and the tool holder 3 is existing technology and will not be described in detail in this embodiment.

[0029] A storage box 5 for stockpiling materials is fixedly connected to the frame 1. Multiple metal shafts are placed inside the storage box 5. A guide ramp 6 that slopes downward toward the limiting plate 7 is provided on the bottom wall of the storage box 5, so that the metal shafts roll down and accumulate at the lower part of the box due to gravity.

[0030] The transmission mechanism includes a pusher plate 9, a transmission plate 11, and a limiting plate 7. The limiting plate 7 is fixed to the frame 1 and is vertically arranged. The limiting plate 7 has a limiting groove 8 along the height direction of the frame 1, and the pusher plate 9 is slidably connected in the limiting groove 8. A first power component 13, which is a cylinder, is fixed on the frame 1. The first power shaft of the first power component 13 extends out and is fixedly connected to the lower surface of the pusher plate 9. An inclined bearing surface 10 is provided at the upper end of the pusher plate 9, and the size of the bearing surface 10 is limited to be able to support only one metal shaft at a time.

[0031] During operation, the first power component 13 drives the pusher plate 9 to rise, and the bearing surface 10 catches the single metal shaft and lifts it over the top of the limiting plate 7. Subsequently, the metal shaft slides smoothly down along the guide plate 11 and finally falls into the guide groove 12 horizontally opened on the frame 1. The guide plate 11 is fixed to the frame 1.

[0032] The support frame 15 is fixed to the frame 1. A vertically arranged second power component 16, which is a cylinder, is fixedly connected to the support frame 15. A third power component 18, which is a rotary cylinder, is fixedly connected to the second power shaft 17 of the second power component 16. A horizontally arranged rotating component 20 is fixedly connected to the third power shaft 19 of the third power component 18. The rotating component 20 has a horizontally through-hole 21 inside.

[0033] The second power component 16 drives the third power component 18 and the rotating component 20 to remain in a high position, aligning the placement hole 21 on the rotating component 20 with the guide groove 12 on the frame 1 on the same axis. After the metal shaft falls into the guide groove 12 and is temporarily stored, it needs to be moved into the placement hole 21. A seventh power component 33 is provided on the frame 1. The seventh power shaft 34 of the seventh power component 33 extends forward and abuts against the end face of the metal shaft, smoothly pushing the metal shaft along the guide groove 12 into the aligned placement hole 21 of the rotating component 20. The seventh power component 33 is a cylinder.

[0034] A connecting groove 22 is formed on the inner wall of the placement hole 21. A high-hardness pressure roller 23 is installed in the connecting groove 22. The outer wall of the pressure roller 23 may have anti-slip knurling or model lettering. An abutment block 35 is fixedly connected to the outer wall of the seventh power shaft 34. When the seventh power shaft 34 pushes the material forward, the abutment block 35 pushes the slide rod 28, which is slidably connected to the rotating part 20, causing it to move along the length of the rotating part 20. The slide rod 28 overcomes the resistance of the second elastic element 30 and slides along the axial direction of the placement hole 21. The second elastic element 30 is a spring.

[0035] A third inclined surface 29 is provided at the end of the slide rod 28 away from the contact block 35. This third inclined surface 29 will press against the outer wall of the displacement shaft 26 when it moves. The displacement shaft 26 is fixedly connected to the displacement block 25, and the displacement block 25 is slidably connected in the straight groove 24, which communicates with the placement hole 21. A third elastic element 27 is connected between the displacement block 25 and the inner wall of the straight groove 24. The third elastic element 27 is a spring. Under the wedge-shaped pressing action of the third inclined surface 29, the displacement block 25 overcomes the elastic force of the third elastic element 27 and moves radially towards the center of the placement hole 21, thereby pushing a part of the pressure roller 23 into the placement hole 21.

[0036] As the metal shaft continues to move forward, the outer surface of the metal shaft rolls and presses against the pressure roller 23, which is in a convex locked state, directly pressing anti-slip patterns or marks onto the surface of the metal shaft using a single push displacement.

[0037] Meanwhile, to prevent the metal shaft from falling out, a positioning groove 31 is provided on the inner wall of the placement hole 21, and a U-shaped spring piece 32 is installed in the positioning groove 31. The spring piece 32 is made of high-toughness spring steel, with its two ends fixed to the inner wall of the positioning groove 31 and its middle protruding into the placement hole 21. When the metal shaft enters the placement hole 21, it will cause the spring piece 32 to undergo elastic deformation, and the radial rebound force generated by the spring piece 32 will press against the metal shaft.

[0038] After the marking and feeding are completed and the seventh power shaft 34 retracts, the second power component 16 is activated, driving the third power component 18 and the rotating component 20 to move downwards as a whole, so that the placement hole 21 of the rotating component 20 is precisely aligned with the gripper 53 at the same center height. In order to feed the metal shaft into the gripper 53, a fourth power component 36, which is a cylinder, is fixedly connected to the housing of the third power component 18. The fourth power shaft 37 of the fourth power component 36 extends out, passes through the placement hole 21, overcomes the frictional resistance of the spring 32, and pushes the metal shaft into the gripper 53, which is in the open state.

[0039] A support tube 38 is slidably connected to the frame 1 along its length, and the support tube 38 is located inside the frame 1. A support ring (not shown in the figure) is fixedly connected inside the frame 1, and the support tube 38 passes through the support ring to support the support tube 38. A toothed ring 40 is fixedly fitted on the outer wall of the support tube 38. The toothed ring 40 has spur teeth. A power motor 41 is fixed to the frame 1 and is used to drive the power wheel 42 to rotate. The power wheel 42 is engaged with the toothed ring 40, thereby driving the support tube 38 and the gripper 53 to rotate. The power wheel 42 is a spur gear.

[0040] A sixth power component 43, which is a cylinder, is fixedly connected to the frame 1. The sixth power shaft 44 of the sixth power component 43 is connected to the support tube 38 via a connecting mechanism. The connecting mechanism includes a left positioning ring 45 and a right positioning ring 46, which are fixedly combined to form a positioning cavity. A fixing ring 48, fixedly connected to the outer wall of the support tube 38, is located within this positioning cavity. The fixing ring 48 can be connected to the inner wall of the positioning cavity via a bearing. The right positioning ring 46 is fixedly connected to the sixth power shaft 44.

[0041] When the support tube 38 is pulled away from the tool holder 3, the linkage mechanism causes the gripper 53 to retract. The linkage mechanism includes a first inclined surface 56, a first elastic element 55, a positioning plate 49, a positioning sleeve 50, a sliding groove 51, and a slider 52. The positioning plate 49 is fixed to the outer wall of the support tube 38, and the positioning sleeve 50 is rotatably connected to the frame 1 via bearings. The positioning sleeve 50 is slidably connected to the gripper 53. The gripper 53 includes multiple clamping plates 54. A sliding groove 51 extending towards the axis is formed on the positioning plate 49, and the slider 52 is slidably connected to the sliding groove 51 and fixedly connected to the clamping plate 54. One slider 52 is connected to one clamping plate 54. A first elastic element 55, which is a spring, is connected between the slider 52 and the positioning plate 49.

[0042] A first inclined surface 56 is provided on the inner wall of the positioning sleeve 50, and a second inclined surface 57 is provided on the outer wall of the clamping plate 54. When the support tube 38 retracts to pull the positioning disc 49, the second inclined surface 57 on the clamping plate 54 is forced to slide against the first inclined surface 56 of the positioning sleeve 50, converting the axial tension into a radially inward thrust. This forces multiple clamping plates 54 to overcome the tension of the first elastic element 55 and simultaneously contract towards the axis, thereby achieving centered clamping of the metal shaft.

[0043] After the gripper 53 clamps the metal shaft, the power motor 41 operates, and the tool holder 3 feeds along the guide rails of the support base 2 and the frame 1, using the tool 4 to complete the machining of the first exposed end face of the metal shaft. After machining, the sixth power component 43 pushes the support tube 38 forward, the first elastic component 55 pulls the slider 52 to reset, and the gripper 53 releases. At this time, the fifth power component 58, fixed at the tail of the frame 1, actuates. The fifth power component 58 is a cylinder. Since the support tube 38 is hollow, the fifth power shaft 59 of the fifth power component 58 passes directly through the support tube 38 and the interior of the gripper 53, pushing the machined end of the metal shaft outward from the gripper 53, causing it to fall back into the placement hole 21 of the rotating component 20 waiting in front.

[0044] Subsequently, the second power component 16 drives the rotating component 20 to rise and avoid obstruction, while the third power component 18 drives the rotating component 20 to rotate horizontally 180 degrees, turning the metal shaft around. Next, the rotating component 20 moves down and aligns with the gripper 53 again, and the fourth power component 36 pushes the metal shaft into the gripper 53 and clamps it. The second power component 16 drives the rotating component 20 to rise and avoid obstruction. The tool holder 3 feeds again to complete the machining of the second end face of the metal shaft. When the machining of both end faces of the metal shaft is complete, the gripper 53 releases, and the fifth power component 59 extends again, completely ejecting the finished metal shaft from the gripper 53 for unloading.

[0045] To achieve automatic collection of metal shafts, an inclined feed plate 60 is fixedly connected to the front side of the tool holder 3. The ejected metal shafts fall onto the feed plate 60 and automatically roll down the inclined guide surface to the finished product collection area below, and the equipment then enters the next processing cycle.

[0046] Of course, the above are just typical examples of the present invention. In addition, the present invention may have many other specific embodiments. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by the present invention.
