Description

Technical Field

[0001] This invention relates to the field of gear blank transport technology, and in particular to a gear blank chamfering forming feeding assembly. Background Technology

[0002] When machining gears from blanks, in order to improve assembly convenience, increase the wear resistance and mechanical strength of the blanks, eliminate manufacturing defects, and reduce friction and wear, a chamfering cutter is usually used to cut both ends of the cylindrical blank to remove excess material from both ends of the cylindrical blank and form a chamfered structure.

[0003] In existing technologies, cylindrical blanks are typically transported to the cutting device one by one manually for processing. This not only increases labor costs but also reduces cutting efficiency, which is not conducive to the production of batch gear products.

[0004] Therefore, there is an urgent need for an automated gear blank chamfering and forming feeding assembly. Summary of the Invention

[0005] The purpose of this invention is to overcome the defects in the prior art and provide a gear blank chamfering forming feeding assembly that reduces labor costs and improves production efficiency.

[0006] To achieve the above-mentioned technical effects, the technical solution of the present invention is as follows: a gear blank chamfering forming feeding assembly, used to output cylindrical blanks with a length greater than the outer diameter one by one, comprising: A conveying assembly, comprising a conveyor and an interceptor, wherein the conveyor has a horizontal conveying surface for conveying a billet, the length direction of the conveying surface is a first direction, the width of the conveying surface is less than twice the outer diameter of the billet, and the interceptor is disposed directly above the conveying surface and adjacent to the output end of the conveyor. A conveying assembly, comprising a clamp and a moving assembly, wherein the moving assembly drives the clamp to move between a clamping station and a releasing station, the clamp at the clamping station being used to clamp a blank located on the conveying surface and abutting against the interceptor, and the clamp at the releasing station being used to release the blank. The feeding assembly includes at least three stepped members that are sequentially attached. The top surface of each stepped member is a feeding ramp extending along a first direction with a length greater than the length of the billet and a width greater than half the outer diameter of the billet. The side of the feeding ramp adjacent to the conveyor is lower than the other side of the feeding ramp. In two adjacent stepped members, at least one of the feeding ramps has a width less than 1.5 times the outer diameter of the billet. Each stepped member includes at least two fixed steps arranged sequentially with intervals between them and a movable step located between two adjacent fixed steps. The height of the feeding ramp of the fixed step is negatively correlated with the horizontal distance between itself and the conveyor. The feeding ramp of the fixed step adjacent to the conveyor is close to the upper side of the conveying surface. The movable step is connected to a movable unit that drives itself to move in a straight line between the loading station and the unloading station. At the unloading station, the feeding ramp of the movable step is located below the feeding ramps of the two adjacent fixed steps. At the loading station, the feeding ramp of the movable step is located above the feeding ramps of the two adjacent fixed steps.

[0007] Preferably, in order to achieve stable conveying of the billet, the fixed steps and the movable steps are distributed at intervals in sequence.

[0008] Preferably, in order to improve the efficiency of billet supply, reduce the number of moving units, and lower the cost of the device, at least two moving steps are provided and fixedly connected to each other, and the moving unit drives each moving step to move simultaneously in a straight line.

[0009] Preferably, in order to facilitate the assembly of the feeding components and ensure a stable supply and conveying of the blank, the distribution interval of adjacent fixed steps is consistent with the distribution interval of adjacent movable steps in the direction perpendicular to the moving direction of the movable steps.

[0010] Preferably, to prevent the billet from falling from both ends of the feeding ramp during the feeding process, the two ends of the step are provided with baffles, the top of which is higher than the feeding ramp of the step, so as to form an upward feeding bucket with the step.

[0011] Preferably, to prevent the billet from rolling off the conveying surface during the conveying process, both sides of the conveyor are provided with limiting strips extending along the first direction to the adjacent interceptor. The limiting strips and the conveying surface combine to form a conveying groove with the opening facing upward and extending along the first direction.

[0012] Preferably, in order to facilitate the screening of billets whose axis extends vertically on the transmission surface and to ensure that billets with horizontal axis can move smoothly with the transmission surface, the conveyor is provided with a material guide located at the end of the transmission groove away from the interceptor. The material guide is positioned directly above the transmission surface, and the distance between the material guide and the transmission surface is less than the length of the billet and greater than the outer diameter of the billet.

[0013] Preferably, in order to guide the billet whose axis of rotation on the original conveying surface extends vertically to the feeding ramp so that it can return to the conveying surface horizontally through the feeding assembly, a return channel is also provided at the end of the conveying groove away from the interceptor. The return channel extends downward and is located on the same side of the conveyor as the feeding assembly. The feeding channel allows the billet intercepted by the feeder to fall back onto the feeding ramp of one of the stepped components.

[0014] Preferably, in order to facilitate the smooth guidance of the billet whose axis extends vertically along the transmission surface into the return channel, the side of the material feeder adjacent to the input end of the conveyor is a guide surface. The two ends of the guide surface are a detection end and a guide end respectively located on both sides directly above the transmission surface. The guide end extends into the return channel. Along the first direction, the horizontal distance between the detection end and the input end of the conveyor is less than the horizontal distance between the guide end and the input end of the conveyor. The detection end is gradually transitioned to the guide end.

[0015] Preferably, in order to ensure a stable supply of billets, reduce the movement path length of the movable steps, and improve the billet supply efficiency, when the movable steps move to the loading and unloading stations, among any three adjacent step components, only two of the step components have their feeding ramps located on the same plane.

[0016] In summary, compared with the prior art, the gear blank chamfering forming feeding assembly of the present invention drives the movable steps to move in a straight line between the loading and unloading stations through the movable unit. This allows the cylindrical blank to pass through the ramps of adjacent step components in sequence and finally fall onto the conveying surface of the conveyor. Moving along the conveying surface facilitates gripping by the fixture and movement by the moving components, realizing automated one-by-one conveying of the blanks. This reduces labor costs and improves blank processing efficiency. Attached Figure Description

[0018] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solutions of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0019] like Figures 12-25 As shown, the gear blank chamfering forming feeding assembly of the present invention is used to output cylindrical blanks 1 with a length greater than the outer diameter one by one, including: The rack 2 includes a base 22 and two transmission fixing frames 21. The two transmission fixing frames 21 are distributed horizontally and arranged vertically. The transmission fixing frames 21 and the base 22 are fixed to the ground. The conveying assembly 3 includes a conveyor 31 and an interceptor 32. The conveyor 31 has a horizontal conveying surface for conveying the blank 1. The length direction of the conveying surface is a first direction. The width of the conveying surface is less than twice the outer diameter of the blank 1. The interceptor 32 is disposed directly above the conveying surface and adjacent to the output end of the conveyor 31. The conveying assembly 4 includes a clamp 41 and a moving assembly 42. The moving assembly 42 drives the clamp 41 to move between a clamping station and a releasing station. The clamp 41 at the clamping station is used to clamp the blank 1 located on the conveying surface and abutting against the interceptor 32. The clamp 41 at the releasing station is used to release the blank 1. The feeding assembly 5 includes at least three stepped members 51 that are sequentially attached. The top surface of each stepped member 51 is a feeding ramp 511 extending along a first direction with a length greater than the length of the billet 1 and a width greater than half the outer diameter of the billet 1. The side of the feeding ramp 511 adjacent to the conveyor 31 is lower than the other side of the feeding ramp 511. In two adjacent stepped members 51, at least one of the feeding ramps 511 has a width less than 1.5 times the outer diameter of the billet 1. Each stepped member 51 includes at least two fixed steps 512 arranged sequentially with intervals between them and a movable step 513 located between two adjacent fixed steps 512. The height of the feeding ramp 511 of the fixed step 512 is negatively correlated with the horizontal distance between itself and the conveyor 31. The feeding ramp 511 of the fixed step 512 adjacent to the conveyor 31 is close to the upper side of the conveying surface. The movable step 513 is connected to a movable unit 52 that drives itself to move in a straight line between the loading station and the unloading station. At the unloading station, the feeding ramp 511 of the movable step 513 is located below the feeding ramps 511 of the two adjacent fixed steps 512. At the loading station, the feeding ramp 511 of the movable step 513 is located above the feeding ramps 511 of the two adjacent fixed steps 512.

[0020] The device of this invention is mainly used to provide a blank 1 to a cutting device. The blank 1 is cylindrical and its length is greater than its outer diameter. The cutting device cuts both ends of the blank 1 to remove excess material and forms chamfers on both ends of the blank 1 to facilitate processing into gears. In the feeding assembly 5 of the device, there are at least three stepped components 51 connected in sequence. The top surface of the stepped component 51, that is, the feeding ramp 511, is inclined and faces downward toward the side where the conveying assembly 3 is located, so that the cylindrical blank 1 can tilt downward along the feeding ramp 511 when it is on the top surface of the stepped component 51. Among the multiple stepped components 51, at least two are fixed steps 512 and some are movable steps 513. The fixed steps 512 are fixed in position, while the movable steps 513 are connected to the movable unit 52. The movable steps 513 are driven by the movable unit 52 to move back and forth between the loading station and the unloading station in a straight line.

[0021] For ease of explanation, the side of the step 51 facing the conveying assembly 3 is the feeding side, and the side facing away from the conveying assembly 3 is the backing side. In use, a batch of blanks 1 is placed on the feeding ramp 511 of the lowest fixed step 512 (i.e., the fixed step 512 furthest from the conveying assembly 3). The blanks 1 roll down the feeding ramp 511, approaching the conveying assembly 3 and resting against the side of the movable step 513 adjacent to the fixed step 512. Then, the movable unit 52 moves the movable step 513 downwards to the unloading station, so that the feeding ramp 511 of the movable step 513 is located at the feeding position of the fixed step 512. Below the ramp 511, since the width of the feeding ramp 511 of the step component 51 is greater than half of the outer diameter of the billet 1, and at least one of the feeding ramps 511 of two adjacent step components 51 is less than 1.5 times the outer diameter of the billet 1, when the movable unit 52 drives the movable step 513 to move upward to the loading station, the billet 1 can be lifted upward by the feeding ramp 511 of the movable step 513. When the movable step 513 moves to the loading station, it rolls down along the feeding ramp 511 of the movable step 513 and lands on the feeding ramp 511 of the fixed step 512 on the feeding side of the movable step 513.

[0022] Using the above method, the movable step 513 is driven by the movable unit 52 to reciprocate between the loading station and the unloading station, causing the cylindrical billet 1 to roll down the inclined feeding ramp 511 towards the conveying assembly 3. Finally, the billet 1 passes through the feeding ramp 511 closest to the fixed step 512 of the conveyor 31, rolls down the feeding ramp 511, and lands on the conveying surface of the conveyor 31. In this way, the function of conveying the billet 1 to the conveying surface of the conveyor 31 is realized. Due to the adjacent two step components 5 In the feeding ramps 511 of 1, at least one of the feeding ramps 511 has a width less than 1.5 times the outer diameter of the billet 1, so that on the feeding ramps 511 of two adjacent step members 51, along the inclination direction of the feeding ramps 511, the feeding ramps 511 can only carry at most one row of billets 1. The billets 1 are distributed along the first direction. As the movable unit 52 drives the movable step 513 to move back and forth, the row of billets 1 eventually falls on the conveying surface of the conveyor 31. Thus, each billet 1 is distributed along the length direction of the conveying surface of the conveyor 31. The conveyor 31 remains operational, causing the billet 1 on the conveying surface to move along the first direction. Finally, after the billet 1 rests against the interceptor 32, the moving component 42 adjusts the clamp 41 to the clamping position, clamping the billet 1 that is in contact with the interceptor 32 on the conveying surface. Then, the moving component 42 adjusts the clamp 41 to the release position, where the clamp 41 releases the clamped billet 1, allowing the cutting device to cut the released billet 1 and form a chamfer on the end face. The moving component 42 then moves the clamp 41 back to the clamping position to clamp the billet 1 that is in contact with the interceptor 32 on the conveying surface. After clamping, the clamp 41 is moved back to the release position to release the clamped billet 1. In this way, the feeding component, through the coordinated operation of the feeding component 5, the handling component 4, and the conveying component 3, achieves the orderly and continuous output of the billet 1, reducing manual operation, lowering labor costs, and thus improving production efficiency.

[0023] In this invention, the specific structure of the transmitter 31 is as follows: Figures 12-15As shown, the conveyor 31 includes two conveyor side plates 315, which are vertically arranged and spaced apart along a horizontal direction perpendicular to the first direction. The length direction of both conveyor side plates 315 is the first direction. The two conveyor side plates 315 are fixed to two conveyor fixing frames 21 and are fixedly connected by connecting profiles 318 of the same length direction. Each end of the two conveyor side plates 315 is provided with a conveyor bearing 317. A chain 314, which is generally oval and whose length direction is the first direction, is arranged between the two conveyor side plates 315. The connecting profile 318 is located inside the chain 314, and both ends of the connecting profile 318 are provided with… The device is equipped with a drive sprocket 312 and a driven sprocket 313, which are connected by a chain 314. A rotating shaft 316 with the same axis as the driven sprocket 313 is fixedly inserted through the inner side of the driven sprocket 313. A transmission motor 311 is fixed to the end of one of the transmission side plates 315 and its output shaft is fixedly connected with the drive sprocket 312 with the same axis as the driven sprocket 312. Transmission bearings 317 are provided at both ends of the output shaft of the transmission motor 311 and at both ends of the rotating shaft 316. The outer ring of the transmission bearing 317 is fixed on the transmission side plate 315. The top surface of the upper layer of the chain 314 forms the transmission surface of the transmission machine 31. The width of the chain 314 is consistent with the outer diameter of the blank 1.

[0024] After the transmission machine 31 adopts the above structure, the transmission motor 311 drives the drive sprocket 312 to rotate stably under the support of the transmission bearing 317. Utilizing the transmission relationship between the drive sprocket 312, the driven sprocket 313 and the chain 314, the chain 314 can rotate along its own circumference. Since the waist length direction of the chain 314 is the first direction, the blank 1 falling on the chain 314 can move along the first direction as the chain 314 rotates. The interceptor 32 is located directly above the output end of the conveyor surface of the conveyor 31. Specifically, the interceptor 32 is a U-shaped structure fixed on the conveyor side plate 315, with its U-shaped opening facing the output end of the conveyor 31. A through-hole-shaped positioning through-hole 321 is provided on the bottom wall of the U-shaped opening of the interceptor 32. The inner diameter of the positioning through-hole 321 is much smaller than the outer diameter of the blank 1. A positioning sensor 36 facing the positioning through-hole 321 is fixed on the inner side of the U-shaped opening. The positioning sensor 36 is a distance sensor facing the positioning through-hole 321. When the blank 1 moves with the operation of the conveyor 31 to contact the interceptor 32, the positioning sensor 36 detects the contact distance signal, and the device controls the transport component 4 to operate. The position of the clamp 41 is adjusted by the moving component 42, and the clamp 41 is moved to the clamping position to clamp the blank 1 that is in contact with the interceptor 32.

[0025] A transmission limiting frame 38 is also provided between the input and output ends of the transmission surface of the transmission machine 31. The transmission limiting frame 38 is a U-shaped frame with the opening facing downwards, such as... Figure 12 and Figure 13As shown, the bottom of the two inner side walls of the transmission limiting frame 38 is fixedly connected to the two transmission side plates 315. The transmission limiting frame 38 and the chain 314 enclose a limiting channel. The length and width of the limiting channel are slightly larger than the outer diameter of the blank 1, facilitating the passage of the blank 1. The distance between the limiting channel and the interceptor 32 is between one and two times the length of the blank 1. This prevents the two adjacent blanks 1 from being clamped by the clamp 41 when moving on the transmission surface, such as when one blank 1 abuts against the interceptor 32. Figure 2 As shown, another blank 1 is affected and detaches from chain 314, causing blank 1 to fall and affecting the transmission. A transport fixing frame 37 is fixed directly above the interceptor 32. The transport fixing frame 37 is used to fix and install the transport assembly 4. The specific structure of the transport assembly 4 is as follows... Figure 16 and Figure 17 As shown, specifically, in the handling assembly 4, the clamp 41 includes a gripping frame 413 and two gripping units. The two gripping units are arranged opposite each other at both ends of the gripping frame 413 along a horizontal direction perpendicular to the first direction. Each gripping unit includes a gripping cylinder 412 and a gripper 411. The cylinder barrels of the two gripping cylinders 412 are arranged opposite each other along a horizontal direction perpendicular to the first direction and fixed below the gripping frame 413. The piston rod is fixedly connected to the gripper 411. The opposite sides of the two grippers 411 are both arc surfaces, and the diameter of the arc surface is the same as the outer diameter of the blank 1. The moving assembly 42 includes a moving fixed frame 421, which is fixed on the handling fixed frame 37. The moving fixed frame 421 is provided with a moving guide rail 4211 of the same length as the gripping cylinder 412 and a first moving cylinder 422. The cylinder of cylinder 22 is fixedly connected to the movable fixed frame 421. The piston rod is connected to the first movable frame 423. The first movable frame 423 is slidably engaged with the movable guide rail 4211. The second movable cylinder 426, the second movable frame 427 and the third movable cylinder 428 are arranged sequentially from top to bottom below the first movable frame 423. The first movable frame 423 is also provided with a second movable guide sleeve 424 extending in the vertical direction. The inner side of the second movable guide sleeve 424 is slidably provided with a second guide rod 425. The bottom end of the second guide rod 425 is fixedly connected to the gripping frame 413. The cylinder of the second movable cylinder 426 is downward and fixed on the first movable frame 423. The piston rod is fixedly connected to the second movable frame 427. The cylinder of the third movable cylinder 428 is downward and fixed below the second movable frame 427. The bottom end of the piston rod is fixedly connected to the gripping frame 413.

[0026] After the handling assembly 4 adopts the above structure, the first moving frame 423 is driven by the first moving cylinder 422 to move smoothly along the length direction of the moving guide rail 4211, adjusting the horizontal position of the clamp 41. The second moving cylinder 426 and the third moving cylinder 428 drive the gripping frame 413 to move stably up and down in the vertical direction under the sliding cooperation of the second moving guide sleeve 424 and the second guide rod 425, thereby adjusting the height position of the clamp 41. That is, through the coordinated operation of the first moving cylinder 422, the second moving cylinder 426, and the third moving cylinder 428, the working position of the clamp 41 is adjusted, allowing it to move between the release position and the gripping position. Specifically, when the blank 1 abuts against the interceptor 32, the clamp 41 moves to the gripping position, and the gripping cylinder 412 controls the two grippers 411 to move closer together to grip the blank 1. Figure 2 As shown, the clamp 41 then moves to the release position, and the gripping cylinder 412 controls the two grippers 411 to move away from each other, releasing the gripped billet 1, as shown. Figure 5 As shown.

[0027] A further improvement is that both sides of the conveyor 31 are provided with limiting strips 33 extending along the first direction to be adjacent to the interceptor 32. The limiting strips 33 and the conveying surface combine to form a conveying groove with the opening facing upward and extending along the first direction. Specifically, the two limiting strips 33 correspond one-to-one with the two conveying side plates 315 and are in the same length direction. The limiting strips 33 are fixed to the side of the conveying side plate 315 away from the connecting profile 318, so that the upper layer of the chain 314 and the two limiting strips 33 combine to form a conveying groove. The conveying groove extends along the first direction and the groove depth is greater than the radius of the blank 1. In this way, the limiting strips 33 can prevent the blank 1 on the conveying surface from rolling off the sides of the conveying surface. By limiting the blank 1 in the horizontal direction perpendicular to the first direction, the conveyor 31 can ensure the stable conveying of the blank 1.

[0028] A further improvement is that fixed steps 512 and movable steps 513 are distributed alternately; at least two movable steps 513 are provided and fixedly connected, and the movable unit 52 drives each movable step 513 to move simultaneously in a straight line; along the direction perpendicular to the moving direction of the movable steps 513, the distribution interval of adjacent fixed steps 512 is consistent with the distribution interval of adjacent movable steps 513; both ends of the step member 51 are provided with stop members 53, the top of the stop members 53 is higher than the feeding ramp 511 of the step member 51, so as to form an upward feeding bucket with the step member 51. The feeding assembly 5 is located adjacent to the input end of the conveyor 31, and its specific structure is as follows. Figures 8-11As shown, the feeding assembly 5 includes a feeding base plate 54, which is fixed to the ground with its length in the first direction. A feeding front panel 55 and a feeding back panel 56 are respectively installed above both ends of the feeding base plate 54. Plate-shaped baffles 53 are installed above both sides. The feeding front panel 55, feeding back panel 56, and two baffles 53 are all vertically arranged and sequentially fixed to form a frame structure. The feeding front panel 55 is located on the side of the feeding back panel 56 facing away from the conveyor 31. Steps 51 and movable units 52 are located inside the frame structure. Specifically, there are seven steps 51, spaced apart and sequentially fitted with four fixed steps 512 and three movable steps 513. One fixed step 512 is fixedly connected to the feeding front panel 55 and its width is much greater than the widths of the other steps 51. The remaining three fixed steps 512 and three movable steps 513 are inclined and have the same thickness. The stepped plate ensures that the distribution interval of adjacent fixed steps 512 is consistent with the distribution interval of adjacent movable steps 513 along the direction perpendicular to the moving direction of movable steps 513, which facilitates assembly; the two ends of the four fixed steps 512 are respectively fixedly connected to two material stop parts 53, and the two ends of the three movable steps 513 are respectively attached to two material stop parts 53; the top surface of the seven step parts 51 are all inclined downward feeding ramps 511, the length direction of the feeding ramps 511 is the first direction, the side of the feeding ramps 511 adjacent to the conveyor 31 is lower than the other side of the feeding ramps 511, so that after the blank 1 is placed on the feeding ramps 511, it can roll down the feeding ramps 511 and move towards the conveyor 31; among the seven feeding ramps 511, the slope length of the feeding ramp 511 integrally connected with the feeding front panel 55 is much greater than the outer diameter of the blank 1, while the slope length of the other six feeding ramps 511 is consistent with the outer diameter of the blank 1. Of the four fixed steps 512, the feeding ramp 511 of the fixed step 512 closest to the conveyor 31 is on the same plane as the top of the feeding back panel 56, and a feeding transition plate 57 is fixed on the side of the feeding back panel 56 away from the fixed step 512. The top surface of the feeding transition plate 57 is on the same plane as the feeding ramp 511 of the fixed step 512, and it is adjacent to the side above the conveying surface. The end of one of the limiting strips 33 is directly opposite to the feeding transition plate 57.

[0029] The movable unit 52 includes a movable cylinder 521 and a movable frame 522. The cylinder of the movable cylinder 521 is inclined upward and fixed above the feeding base plate 54. The piston rod is fixedly connected to the bottom of the movable frame 522. Three sets of connecting rods are provided on the movable frame 522, and the tops of the three sets of connecting rods are fixedly connected to the bottoms of the three movable steps 513 respectively. With the above structure, the feeding assembly 5 forms a feeding barrel with an open top, and the inner bottom wall of the feeding barrel is inclined and stepped. Because the length of the feeding ramp 511, which is integrally connected to the feeding front panel 55, is much greater than the outer diameter of the billet 1, it is convenient for operators to place multiple billets 1 on the feeding ramp 511. The baffle 53 can prevent the billet 1 from detaching from both ends of the feeding ramp 511 during the feeding process. During device operation, the movable cylinder 521 in the movable unit 52 drives the movable frame 522 to reciprocate, allowing the three fixed steps 512 to reciprocate simultaneously between the unloading and loading stations. Because any two adjacent steps... 51 are fitted together, therefore, any three adjacent step pieces 51 are selected, and the bottom end of the middle step piece 51 is always below the feeding ramp 511 of the end step piece 51. When the feeding assembly 5 is running, the movable unit 52 drives the movable step 513 to move to the loading station. On the fixed step 512 on the back side of the movable step 513, the billet 1 rolls down along the feeding ramp 511 of the fixed step 512 until it contacts the side of the movable step 513. Then the movable unit 52 drives the movable step 513 to move to the lower... At the material feeding station, the feeding ramp 511 of the movable step 513 is located below the feeding ramp 511 of the fixed step 512 on its back side, allowing the billet 1 to roll from the feeding ramp 511 of the fixed step 512 to the feeding ramp 511 of the movable step 513, and rest against the side of the fixed step 512 on the feeding side of the movable step 513. The movable unit 52 then drives the movable step 513 to move to the loading station, so that the feeding ramp 511 of the movable step 513 is higher than the feeding ramp 511 of the fixed step 512 on its feeding side. The slope 511 facilitates the rolling of the billet 1 from the feeding ramp 511 of the movable step 513 on the back side to the feeding ramp 511 of the fixed step 512 on the feed side. Thus, the movable step 513 is driven to move back and forth by the movable unit 52, and finally the billet 1 is transferred to the feeding ramp 511 of the fixed step 512 closest to the conveyor 31. The billet 1 rolls down the top surface of the feeding ramp 511 and the top surface of the feeding transition plate 57 to the top surface of the chain 314, that is, the transmission surface. The limiting strip 33 prevents the billet 1 from rolling off the transmission surface.

[0030] A further improvement is that when the movable step 513 moves to the loading and unloading stations, among any three adjacent step components 51, exactly two of them have their feeding ramps 511 located on the same plane. Specifically, as shown in... Figure 9As shown, when all movable steps 513 move to the loading station, the feeding ramp 511 of the fixed step 512 attached to the feeding side of the movable step 513 is on the same plane as the feeding ramp 511 of the movable step 513 and is higher than the feeding ramp 511 of the fixed step 512 on the back side; while when all movable steps 513 move to the unloading station, the feeding ramp 511 of the fixed step 512 attached to the back side of the movable step 513 is on the same plane as the feeding ramp 511 of the movable step 513 and is lower than the feeding ramp 511 of the fixed step 512 on the feeding side. That is, at the loading station, the feeding ramp 511 of the movable step 513 is smoothly connected to the feeding ramp 511 of the fixed step 512 on the feeding side to form a new ramp. At the unloading station, the feeding ramp 511 of the movable step 513 is smoothly connected to the feeding ramp 511 of the fixed step 512 on the back side to form another new ramp, which facilitates the stable rolling of the billet 1 and realizes the stable feeding of the feeding component 5.

[0031] A further improvement is that the conveyor 31 is equipped with a feeder 34 located at the end of the conveying groove away from the interceptor 32. The feeder 34 is positioned directly above the conveying surface, and the distance between the feeder 34 and the conveying surface is less than the length of the billet 1 and greater than the outer diameter of the billet 1. Specifically, the feeder 34 is fixedly positioned directly above the chain 314, and its distance from the conveying surface is greater than the outer diameter of the billet 1 and less than the height of the billet 1. This ensures that if the axis of the billet 1 on the conveying surface is horizontal, the billet 1 is lower than the feeder 34 and can pass under the feeder 34, ultimately abutting against the interceptor 32. Conversely, if the axis of the billet 1 on the conveying surface is horizontal, the billet 1 is lower than the feeder 34 and can pass under the feeder 34, ultimately abutting against the interceptor 32. Figure 13 The billet 1 in the bottom right corner of the diagram has its axis along the vertical direction. Since the length of billet 1 is greater than the distance between the feeder 34 and the conveying surface, billet 1 cannot pass through the feeder 34 and eventually rolls off the conveying surface. Thus, the feeder 34 can screen the billet 1 on the conveying surface, ensuring that the axis of the billet 1 directly below the feeder 34 is horizontal. Finally, one end face of the billet 1 passing through the feeder 34 abuts against the interceptor 32, making it convenient for the handling component 4 to grab and handle it.

[0032] A further improvement is that a return channel 35 is provided at the end of the transmission channel away from the interceptor 32. The return channel 35 extends downward and is located on the same side of the conveyor 31 as the feeding assembly 5. The feeding channel allows the billet 1 intercepted by the feeder 34 to fall back onto the feeding ramp 511 of one of the step members 51. The side of the feeder 34 adjacent to the input end of the conveyor 31 is a guide surface 341. The two ends of the guide surface 341 are a detection end 3411 and a guide end 3412 respectively located on both sides directly above the transmission surface. The guide end 3412 extends into the return channel 35. Along the first direction, the horizontal distance between the detection end 3411 and the input end of the conveyor 31 is less than the horizontal distance between the guide end 3412 and the input end of the conveyor 31. The detection end 3411 is gradually transitioned to the guide end 3412. Specifically, the return channel 35 is a zigzag-shaped return trough with an open top. The return channel 35 and the feeding assembly 5 are located on the same side of the conveyor 31. One end of the return channel 35 is fixed to one of the conveying side plates 315. The bottom of the trough at this end is on the same plane as the conveying surface and is adjacent to it. The other end of the return channel 35 extends to the top of one of the baffles 53 and is located directly above the feeding ramp 511 that is integrally connected with the feeding front panel 55.

[0033] With the above structure, when the billet 1 conveyed by the feeding assembly 5 to the transmission surface is in the vertical direction, the billet 1 moves along the first direction with the operation of the conveyor 31 and comes into contact with the guide surface 341 of the feeder 34. The bottom is affected by the rotation of the chain 314, so that the upper part of the billet 1 tilts down along the guide surface 341 under the influence of the guide surface 341. That is, the upper part of the billet 1 tilts into the return channel 35. After tilting, the billet 1 enters the return channel 35 and rolls down along the return channel 35, and finally falls on the feeding ramp 511 which is integrally connected with the feeding front panel 55. After falling, the axis of the billet 1 is parallel to the feeding ramp 511. Then the movable unit 52 drives the movable step 513 to move back and forth, so that the billet 1 can finally fall on the transmission surface and ensure that the axis of the billet 1 is horizontal.

[0034] like Figures 1-11 As shown, the output end of the feeding assembly of the present invention is provided with a gear blank chamfering forming assembly, which includes: Transfer assembly 6 is used to receive the blank 1 output by the feeding assembly and transfer it to the cutting position. In the cutting position, the axis of the blank 1 extends along a horizontal second direction. The clamping assembly 7 is used to lift the blank 1 at the cutting position until it is separated from the transfer assembly 6 and then clamp the blank 1. The clamping assembly 7 includes an upper clamping seat 71, a lower clamping seat 72 disposed directly below the upper clamping seat 71, and a first adjusting unit 73 for adjusting the distance between the upper clamping seat 71 and the lower clamping seat 72. The bottom position of the lower clamping seat 72 is the material release position, and the top position is the clamping position. The cutting assembly 8 is disposed opposite to the clamping assembly 7 along the second direction; The second distance adjustment component 9 is used to adjust the distance between the cutting component 8 and the clamping component 7; The discharge assembly 10 includes a discharge ramp 101 disposed between the cutting unit and the clamping assembly 7 and parallel to the second direction in width. The spacing of the discharge ramps 101 is less than the length of the blank 1. The extension surface of the discharge ramps 101 along the second direction is located between the clamping position and the discharge position. A collection box 102 is provided at the lower end of the discharge ramps 101. The collection box 102 is used to receive the blank 1 processed by the cutting assembly 8.

[0035] After the feeding assembly outputs cylindrical blanks 1 one by one, the transfer assembly 6 receives the output blanks 1 and transfers them to the cutting position. The clamping assembly 7 then lifts the blanks 1 from the cutting position, allowing them to detach from the transfer assembly 6. The upper clamp 71 and lower clamp 72 clamp the blanks 1. The second adjusting assembly 9 controls the cutting assemblies 8 on both sides to move closer together and cut both ends of the blanks 1, forming chamfers. The second adjusting assembly 9 then controls the cutting assemblies 8 on both sides to move further apart. The first adjusting unit 73 then lowers the position of the lower clamp 72. As the lower clamp 72 descends to the unloading position, the blanks 1 fall onto the discharge ramp 101 of the discharge assembly 10 and roll down the ramp, eventually entering the collection box 102, thus achieving automatic collection of the cut blanks 1. After the blanks 1 detach from the transfer assembly 6, the transfer assembly 6 is adjusted to its initial state to receive the next blank 1 output by the feeding assembly. Thus, through the coordinated operation of the feeding assembly, transfer assembly 6, clamping assembly 7, cutting assembly 8, second distance adjustment assembly 9 and discharge assembly 10, the automatic transfer, clamping, cutting and collection of the blank 1 are realized, which greatly reduces the workload of workers. With the feeding assembly outputting blanks 1 one by one, automated processing and production are realized, thereby greatly improving processing efficiency.

[0036] The specific structure of clamping component 7 is as follows: Figure 21 and Figure 22As shown, the first pitch adjustment unit 73 includes a first pitch adjustment seat 731, a first pitch adjustment cylinder 732, a first pitch adjustment guide rod 733, and a first pitch adjustment guide sleeve 734. The first pitch adjustment seat 731 is fixed directly above the base 22. The cylinder of the first pitch adjustment cylinder 732 is vertically upward and fixed above the first pitch adjustment seat 731. The top end of the piston rod is fixedly connected to the lower clamp 72. The first pitch adjustment guide rod 733 and the first pitch adjustment guide sleeve 734 both extend vertically and slide in cooperation with each other. The first pitch adjustment guide rod 733 is fixed to the lower clamp 734. Below the clamping seat 72, the first adjusting guide sleeve 734 is fixed above the first adjusting seat 731. The upper clamping seat 71 has an upper clamping groove with the opening facing downwards, and is fixedly connected to the first adjusting seat 731 by a clamping fixing bracket 74. The lower clamping seat 72 has a lower clamping groove with the opening facing upwards. The upper clamping seat 71 and the lower clamping seat 72 are arranged opposite each other, and the groove length direction is parallel to the second direction. The groove length is less than the length of the blank 1, preferably one-third to one-half of the length of the blank 1. The feeding position and the clamping position are located directly below and directly above the cutting position, respectively. Figure 7 and Figure 21 As shown. With the above structure, after the transfer assembly 6 transports the blank 1 to the cutting position, the blank 1 is located directly above the lower clamp 72. At this time, the first adjusting cylinder 732 drives the lower clamp 72 to move upward. Under the sliding cooperation of the first adjusting guide rod 733 and the first adjusting guide sleeve 734, the lower clamp 72 moves upward stably, lifting the blank 1 to the clamping position, so that the blank 1 is separated from the transfer assembly 6, making it convenient for the transfer assembly 6 to transfer another blank 1 output by the feeding assembly. At the same time, in the clamping position, the blank 1 is clamped by the upper clamp 71 and the lower clamp 72. The clamping mechanism facilitates the second pitch adjustment component 9 to control the two cutting components 8 to approach each other and perform cutting operations on the end of the billet 1. After the end of the billet 1 is chamfered, the first pitch adjustment cylinder 732 drives the lower clamp 72 to move downward to the unloading position. During the descent, the outer circumferential edge of the billet 1 contacts the top surface of the discharge ramp 101. As the first pitch adjustment cylinder 732 drives the lower clamp 72 to continue descending, the lower clamp 72 disengages from the billet 1, causing the billet 1 to roll down the discharge ramp 101 and finally enter the collection box 102. To transfer the billets 1 output one by one from the feeding component to the cutting position, the specific structure of the transfer component 6 is as follows: Figures 18-20 As shown, the transfer assembly 6 includes transfer slots 61 disposed on both sides of the clamping assembly 7 and extending along the second direction, and a transfer unit 62 that drives the transfer slots 61 to move in a horizontal direction perpendicular to the second direction. The spacing between the transfer slots 61 is greater than the width of the upper clamp 71 and the width of the lower clamp 72, but less than the length of the blank 1.

[0037] More specifically, the transfer assembly 6 also includes a transfer fixing seat 64 and a transfer fixing frame 65. The transfer unit 62 includes a transfer cylinder 621, a transfer frame 622, a transfer connecting seat 623, a transfer guide rod 624, and a transfer guide sleeve 625. The transfer fixing seat 64 is fixed above the base 22 by the transfer fixing frame 65. The cylinder of the transfer cylinder 621 is fixed on the transfer fixing seat 64 in a horizontal direction perpendicular to the first direction. The piston rod is fixedly connected to the transfer frame 622. The axes of the transfer guide rod 624 and the transfer guide sleeve 625 are parallel to the axis of the cylinder of the transfer cylinder 621 and are in sliding fit with each other. The transfer guide sleeve 625 is fixed on the transfer fixing seat 64, and the transfer guide rod 624 is fixed on the transfer frame 622. The transfer frame 622 is provided with two transfer slots 61 distributed along the first direction. Both transfer slots 61 have their openings facing upwards and their length direction is parallel to the first direction. Each transfer slot 61 is a semi-circular slot with an inner diameter consistent with the outer diameter of the billet 1. The distance between the two transfer slots 61 is less than the length of the billet 1 but greater than the width of the upper clamp 71 and the lower clamp 72. The two transfer slots 61 are located on either side of the upper clamp 71. This facilitates the support of the billet 1 by the two transfer slots 61, and the transfer frame 622 is moved to the cutting position by the transfer cylinder 621. Figure 7 As shown, in this position, the first adjusting cylinder 732 drives the lower clamp 72 to move upward, lifting the billet 1 between the two transfer trays 61, causing the billet 1 to disengage from the transfer trays 61, facilitating the retraction of the piston rod of the transfer cylinder 621, and returning it to the position shown. Figure 5 The position shown is for receiving the blanks 1 output one by one from the feed assembly.

[0038] A further improvement is that the sides of the transfer trays 61 that are far apart from each other are closed, and the transfer assembly 6 also includes a third adjusting unit 63 for adjusting the spacing between the transfer trays 61. Specifically, the ends of the two transfer trays 61 that are far apart from each other are both closed by vertically arranged closing plates 611 to prevent the blanks 1 assumed on the two transfer trays 61 from falling off. In addition, the closing plate 611 corresponding to one of the transfer trays 61 is fixedly connected to the transfer frame 622 through a transfer connecting seat 623, and the closing plate 611 corresponding to the other transfer tray 61 is connected to the third adjusting unit 63. The third adjusting unit 63 is a third adjusting cylinder, the cylinder of which extends along the first direction and is fixed to the transfer frame 622, and the piston rod is connected to the end of the closing plate 611 that is far away from the transfer tray 61. With the above structure, when the piston rod of the transfer cylinder 621 drives the transfer tray 61 to retract to the position shown in the image, the transfer assembly 6 further adjusts the spacing between the transfer trays 61 and the transfer assembly 622. Figure 5 At the position shown, the piston rod of the third adjusting cylinder retracts to increase the distance between the two transfer slots 61, making the distance between them slightly larger than the distance between the blanks 1, such as... Figure 19As shown, it is convenient to place the blank 1 on the two transfer slots 61. After the blank 1 is placed, the piston rod of the third adjusting cylinder extends to reduce the distance between the two transfer slots 61, so that the two closing plates 611 fit against the two ends of the blank 1. This ensures the stable transmission of the blank 1 during the transfer process and also fixes the axial position of the blank 1. When the transfer assembly 6 transfers the blank 1 to the cutting position and the clamping assembly 7 lifts and clamps it, the two ends of the blank 1 are at the same distance from the cutting assemblies 8 on both sides. This ensures that the cutting assemblies 8 on both sides process the two ends of the blank 1 in a consistent manner and improves the cutting accuracy of the ends of the blank 1.

[0039] A further improvement is that the cutting assembly 8 includes a cutting seat 81 and a cutting disc 82 whose axis extends parallel to the second direction and rotates about its own axis on the cutting seat 81. A chamfering blade 83 is provided on the side of the cutting disc 82 adjacent to the clamping assembly 7. A rotating unit 84 is connected to the cutting disc 82, and the rotating unit 84 drives the cutting disc 82 to rotate about its own axis. Specifically, as... Figures 21-26 As shown, two second adjusting components 9 are arranged opposite each other, corresponding one-to-one with the two cutting components 8. The second adjusting component 9 includes a second adjusting fixing seat 94 horizontally fixed on the first adjusting seat 731. The second adjusting fixing seat 94 is provided with a second adjusting cylinder 91, a second adjusting guide rail 92, and a second adjusting guide sleeve 93. The cylinder of the second adjusting cylinder 91 extends along the first direction and is fixed on the second adjusting guide rail 92. The second adjusting guide sleeve 93 slides on the second adjusting guide rail 92 and is fixed directly below the cutting seat 81. With the above structure, the second adjusting component 9 drives the cutting seat 81 to move smoothly along the first direction under the guidance of the slidingly fitted second adjusting guide sleeve 93 and the second adjusting guide rail 92 by the extension and retraction of the piston rod of the second adjusting cylinder 91. This changes the position of the two cutting components 8 and realizes the cutting processing of both ends of the blank 1 clamped by the clamping component 7.

[0040] The inner seal of the cutting seat 81 is provided with a concentric shaft 847 with its axis parallel to the first direction. Both ends of the concentric shaft 847 are provided with rotary bearings 848. The outer ring of the rotary bearing 848 is fixedly connected to the concentric shaft 847. The cutting disc 82 is fixedly connected to the inner ring of one of the rotary bearings 848. The rotating unit 84 is fixedly connected to the inner ring of the other rotary bearing 848. The chamfering cutters 83 are arranged in a ring array on the side of the cutting disc 82 away from the concentric shaft 847 with the axis of the concentric shaft 847 as the center line. The rotating unit 84 includes a rotary motor 841, a drive wheel 842, a driven wheel 843, a synchronous belt 844, a protective shell 845, and a cover 846. Specifically, the outer shell of the rotary motor 841 is fixed above the cutting seat 81, and its output end is fixedly connected to the drive wheel 842 along the same axis. The drive wheel 842 is connected to the driven wheel 843 via the synchronous belt 844. The driven wheel 843 is fixedly connected to the inner ring of the rotary bearing 848. The protective shell 845 is open on the side adjacent to the cutting seat 81 and is fixedly connected to the cutting seat 81 via the cover 846. The protective shell 845 and the cover 846 enclose a protective cavity, and the drive wheel 842, the driven wheel 843, and the synchronous belt 844 rotate within the protective cavity.

[0041] With the above structure, after the clamping assembly 7 lifts and clamps the blank 1, the second adjusting assembly 9 controls the cutting seat 81 to move closer to the blank 1. At the same time, the rotary motor 841 in the rotating unit 84 starts, driving the drive wheel 842 to rotate. The drive wheel 842 drives the driven wheel 843 to rotate under the support of the rotary bearing 848 through the synchronous belt 844, so that the concentric shaft 847 and the cutting disc 82 rotate. The chamfering blade 83 on the cutting disc 82 acts on the end of the blank 1, thereby cutting and forming a chamfer at both ends of the blank 1. After the cutting is completed, the rotating unit 84 controls the cutting disc 82 to stop rotating, and the second adjusting component 9 controls the cutting seat 81 to move away from the cut blank 1. Then the piston rod of the first adjusting cylinder 732 moves downward, driving the lower clamp 72 to move downward to the discharge position. During the descent, the blank 1 contacts the slope of the discharge ramp 101. As the lower clamp 72 continues to descend, the blank 1 is separated from the lower clamp 72 and rolls down the discharge ramp 101, eventually entering the collection box 102.

[0042] A further improvement is that the present invention also discloses a cutting assembly 8 according to another embodiment, such as... Figures 26-30As shown, an isolation frame is provided on the side of the cutting seat 81 adjacent to the clamping assembly 7. The cutting disc 82 is located inside the isolation frame. When the cutting assembly 8 cuts the blank 1, the clamping assembly 7 and the cutting assemblies 8 on both sides of the clamping assembly 7 form an isolation cavity surrounding the blank 1 through the upper clamp 71, the lower clamp 72, the isolation frame, and the cutting seat 81. By providing an isolation frame on the side of the cutting seat 81 adjacent to the clamping assembly 7, the two cutting assemblies 8 are brought close to each other. Before cutting the blank 1 clamped and fixed by the clamping assembly 7, the isolation frame, the upper clamp 71, the lower clamp 72, and the cutting seat 81 can form an isolation cavity surrounding the blank 1, preventing the flying of chips generated during cutting and contaminating the surrounding processing environment, ensuring safe cutting processing, and allowing the chips to concentrate in the isolation frame for easy cleaning, reducing the cleaning burden on workers.

[0043] A further improvement is that the isolation frame includes an outer isolation frame 85, an inner isolation frame 86, and an elastic element 87. The circumferential inner wall of the outer isolation frame 85 is sealed to the circumferential outer edge of the inner isolation frame 86. Of the two, the outer isolation frame 85 and the inner isolation frame 86, one is fixed to the cutting seat 81, and the other slides on the cutting seat 81 in a second direction and tends to move toward the clamping assembly 7 through the elastic element 87. Specifically, the isolation frame includes an outer isolation frame 85 and an inner isolation frame 86 distributed along the first direction. The outer isolation frame 85 is fixed to the side of the cutting seat 81 adjacent to the clamping assembly 7. Sliding sleeves 854 are provided on both sides of the outer isolation frame 85. The outer circumferential edge of the inner isolation frame 86 is sealed to the inner circumferential wall of the outer isolation frame 85. Sliding rods 861 are fixedly connected to both sides of the inner isolation frame 86. The sliding rods 861 extend along the first direction and slide in cooperation with the sliding sleeves 854. A protruding plate is fixed to the end of the sliding rod 861. The protruding plate is connected to the cutting seat 81 through an elastic element 87, which is a compression spring. With the above structure, the elastic element 87 applies pressure to the slide rod 861, causing the slide rod 861 to tend to move closer to the clamping assembly 7 along its own axis. This, in turn, causes the inner isolation frame 86 to tend to move away from the cutting seat 81. Thus, when the clamping assembly 7 clamps the blank 1, as the second adjusting cylinder 91 moves the cutting seat 81 closer to the blank 1, the inner isolation frame 86 first contacts the upper clamp 71 and the lower clamp 72. As the cutting seat 81 continues to move, the position of the inner isolation frame 86 remains fixed, while the outer isolation frame 85 moves closer to the cutting seat 81, causing the compression spring to be further compressed. The compression spring applies pressure to the inner isolation frame 86, ensuring a sealed connection between the inner isolation frame 86 and the upper clamp 71 and the lower clamp 72, reducing the gap between the inner isolation frame 86 and the upper clamp 71 and the lower clamp 72, thereby preventing debris from splashing outside the isolation cavity during the cutting process.

[0044] A further improvement is that an air inlet 851 and an air outlet 852 are provided on the side walls of the outer isolation frame 85 and / or the inner isolation frame 86. The cutting assembly 8 also includes an air pump 88, the input end of which is connected to the outside and the output end is connected to the air inlet 851. The air inlet 851 is located directly above the air outlet 852. The air outlet 852 is connected to a chip removal channel 853. A chip collection box 89 for collecting chips is provided at the end of the chip removal channel 853 away from the air outlet 852. Specifically, the air inlet 851 and the air outlet 852 are respectively located on the top and bottom side walls of the isolation frame 85. Both the air inlet 851 and the air outlet 852 are elongated. The projected lengths of the air inlet 851 and the air outlet 852 on the horizontal plane are perpendicular to the first direction. Both the air inlet 851 and the air outlet 852 are directly opposite the chamfering tool 83. The air pump 88 is fixed above the cutting seat 81 by the bracket 882. The input end of the air pump 88 is connected to the air inlet 851 through the air blowing pipe 881.

[0045] With the above structure, while cutting the blank 1, the air pump 88 continues to operate, introducing cold air from the outside. The air is introduced into the isolation chamber through the air pipe 881 and the air inlet 851. Since the air inlet 851 is directly facing the chamfering cutter 83, the cold air flows directly downwards and contacts the chamfering cutter 83 and the blank 1 during cutting, carrying away the heat from the surfaces of the chamfering cutter 83 and the blank 1, thus cooling them down and preventing a decrease in cutting accuracy due to high temperature during the cutting process. In this way, the quality of chamfering and cutting the blank 1 is guaranteed. In addition, since the cold air acts directly downwards on the chamfering cutter 83 and the end of the blank 1, it can also carry away the chips generated during cutting during the downward flow, causing the chips to fall downwards and enter the chip collection box 89 through the chip discharge channel 853, realizing automatic chip collection. Therefore, workers only need to clean the inside of the chip collection box 89 periodically, avoiding frequent cleaning of the chip collection box 89 and further reducing the burden on workers.

[0046] To prevent chips generated during cutting from entering the air pump 88 through the air inlet 851 and causing damage to the air pump 88, a protective net 855 is fixed inside the air inlet 851 to block chips generated during cutting.

[0047] To facilitate cleaning of the chip collection box 89 by workers, the chip collection box 89 is detachably mounted on the first adjustable seat 731. Specifically, the chip collection box 89 has a first insert 891 extending along its own height direction on both sides, and a second insert 735 extending along the vertical direction and corresponding to the first insert 891 is provided on the first adjustable seat 731. The first insert 891 and the second insert 735 are engaged by a pin 75.

[0048] With the above structure, the chip collection box 89 is placed on the first adjustable seat 731, so that the first insert 891 on the chip collection box 89 is aligned with the second insert 735 on the first adjustable seat 731. The pin 75 is inserted to fix the position of the chip collection box 89, so that it is located directly below the chip discharge channel 853, thus facilitating the collection of chips falling from the chip discharge channel 853. After the equipment has been running for a period of time, the pin 75 is removed from the second insert 735, and the chip collection box 89 can be removed from the first adjustable seat 731 for easy cleaning of the inside of the chip collection box 89.

[0049] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
