Description

Technical Field

[0001] The present application relates to the field of feeders, and in particular to a mechanical oil film type automatic bar feeder. Background Art

[0002] In the field of automated production, especially in metal processing, machining, and precision manufacturing, automatic feeding of bar material is a key step in improving production efficiency, reducing labor costs, and ensuring processing accuracy. With the continuous development and advancement of industrial automation technology, the demand for automated feeding equipment is increasing, especially for equipment that is high-precision, high-efficiency, and can flexibly adapt to the processing of bars of different specifications.

[0003] Currently, various mechanical automatic feeding mechanisms exist on the market. A typical design includes a trough, a feeding mechanism, a clamping mechanism, a first drive assembly, a gripping mechanism, and a second drive assembly. This device uses the feeding mechanism to feed the bar into the trough. The clamping mechanism is responsible for clamping the bar at a specific position and, via the first drive assembly, can move between the trough and the tailings collection trough to achieve precise control of the bar. The gripping mechanism is equipped with a sensor that detects the presence of the bar or tailings, and the second drive assembly drives the gripping or release action.

[0004] Since the feeding speeds of bars of different diameters are different, the mechanical automatic feeding mechanism based on the relevant technology has a relatively independent clamping mechanism and a grasping mechanism, and needs to be controlled by different drive components respectively, which increases the cost of the overall drive device of the feeder. Utility Model Content

[0005] In order to reduce the cost of the feeder drive device, the present application provides a mechanical oil film type automatic bar feeder.

[0006] The present application provides a mechanical oil film type bar automatic feeder adopting the following technical solutions:

[0007] A mechanical oil film type automatic bar feeder comprises a frame, a feeding device, an aluminum guide rail device, a clamping device, a feeding device and a driving device; the aluminum guide rail device comprises a detachable polyurethane trough, and a polyurethane trough for conveying bars is provided in the feeding aluminum guide rail; the feeding device is used for bars with a diameter of 2 to 25 and conveys the bars to the polyurethane trough in sequence; the clamping device is used to automatically clamp the bars in the polyurethane trough, and the driving device is used to simultaneously drive the feeding device to discharge the bars and the clamping device to clamp the bars; the feeding device comprises a clamping part for clamping the bars, and the feeding device is used to drive the clamping part to move along the length direction of the frame.

[0008] By adopting the above technical solution, first, a plurality of rods are placed on the unloading device, and the driving device provides power to the unloading device through mechanical linkage to maintain its stable and continuous unloading; the unloading device can ensure that the rods slide into the polyurethane material trough one by one and in an orderly manner; at the same time, the driving device provides power to the clamping device, and the clamping column of the rod is moved by the clamping device, and then the clamping part is pushed toward the direction close to the rod by the feeding device, so that the rod is inserted into the clamping part of the feeding device; finally, the feeding device drives the clamping part and the rod to move in the horizontal direction, so that the end of the rod away from the clamping part is transported to the machine tool for rod processing; when the rod is processed, residual material will be generated, and the residual material is clamped by the clamping device, and then the clamping part is pushed toward the direction away from the clamping device by the feeding device, so that the residual material of the rod and the clamping part are separated from each other, so that the clamping part is convenient for clamping the next rod; by integrating the clamping device and the feeding device, both are controlled by the same driving device at the same time, thereby reducing the cost of the feeder driving device.

[0009] Optionally, the clamping device includes two groups of abutment columns and two groups of rotating arms, one group of abutment columns cooperates with one group of rotating arms, each group of rotating arms includes a rotating swing plate, a rotating shaft and a clamping block, the driving end of the rotating swing plate is provided with a driving edge for tightly fitting with the abutment column, the driving edge is provided with a first recessed section, a convex section and a second recessed section in sequence, the rotating swing plate is rotatably connected to the rotating shaft, the driven end of the rotating swing plate is connected to the clamping block, the clamping block slides through the side wall of the tail material collection trough, and the sensor is installed on the side wall of the tail material collection trough; the driving device is used to drive the two groups of abutment columns to move back and forth to drive the clamping blocks of the two groups of rotating arms to perform a grabbing action.

[0010] By adopting the above technical solution, the abutment column applies force to different sections of the driving edge, and cooperates with the rotating swing plate to implement the lever principle, so that the gripper of the grasping mechanism can clamp and release the rod.

[0011] Optionally, the driving device includes a first driving mechanism, the first driving mechanism includes a sliding assembly and a driving assembly, the sliding assembly includes a first sliding rod and a sliding block, the first sliding rod and the frame slide in cooperation with the driving assembly to drive the first sliding rod to slide in a horizontal direction; the sliding block is fixed on the first sliding rod, and the two abutment columns are both fixed on the sliding block.

[0012] By adopting the above technical solution, when the action of the clamping device needs to be adjusted, the driving component drives the first sliding rod to slide in the horizontal direction, the first sliding rod drives the sliding block to slide in the horizontal direction, and the sliding block simultaneously drives the two abutment columns to move in the horizontal direction, thereby driving the two rotating swing plates to rotate around the rotating axis, thereby automatically driving the clamping device to realize the clamping action and the releasing action in sequence.

[0013] Optionally, the unloading device includes a storage rack and a unloading mechanism, the storage rack is fixed on the frame, and the storage rack is used to store multiple rods; the unloading mechanism includes a first rotating rod, a linkage and a lifting block; the first rotating rod passes through the storage rack and is rotatably connected to the storage rack, and the linkage is fixed on the first rotating rod; the lifting block slides with the storage rack, and the end of the linkage away from the first rotating rod is rotatably connected to the lifting block, and the linkage drives the lifting block to rise and fall when rotating, and the lifting block transfers the rod at the bottom of the storage rack from the storage rack to the feeding channel during the lifting process; the driving device is used to drive the first rotating rod to rotate.

[0014] By adopting the above technical solution, the first rotating rod is driven to rotate by the driving device, and the first rotating rod drives the linkage part to rotate. When the linkage part rises, it pushes down the lowest rod of the storage rack. The rod rolls into the polyurethane trough under the action of its own gravity, thereby realizing automatic unloading.

[0015] Optionally, the driving device also includes a second driving mechanism, the second driving mechanism includes a second sliding rod and a first driving block, the second sliding rod is fixedly connected to the sliding block, the second sliding rod is fixedly connected to the first driving block, and the first driving block is provided with a first driving inclined surface; a first bolt is fixedly provided on the first rotating rod, the first bolt and the axis of the first rotating rod are perpendicular to each other, and the nut of the first bolt abuts against the surface of the first driving inclined surface.

[0016] By adopting the above technical solution, when the first drive mechanism drives the first sliding rod horizontally, the first sliding rod simultaneously drives the sliding block horizontally, thereby driving the clamping device to perform corresponding operations, such as clamping or loosening the material. At the same time, because the second sliding rod is fixedly connected to the sliding block, the movement of the sliding block also drives the second sliding rod in the same horizontal direction. The movement of the second sliding rod is further transmitted to the first drive block to which it is fixed, causing the first drive block to also move horizontally. As the first drive block moves horizontally, the nut of the first bolt slides along the inclined surface of the first driving ramp. Due to the angle of the inclined surface and the fixed position of the bolt, this sliding motion causes the first rotating rod to be subjected to a torque perpendicular to the axis of the first rotating rod. This torque drives the first rotating rod to rotate about its axis, thereby driving the unloading mechanism to unload the material, automatically transferring the rods from the bottom of the storage rack into the polyurethane hopper.

[0017] Optionally, the unloading device is provided with a covering device for covering the feeding aluminum cover plate, the covering device includes an aluminum cover plate, a connecting piece and a second rotating rod, the second rotating rod is rotatably connected to the storage rack, one end of the connecting piece is fixedly connected to the second rotating rod, and the other end of the connecting piece is fixedly connected to the aluminum cover plate; the driving device is used to drive the second rotating rod to rotate.

[0018] By adopting the above technical solution, during the unloading process, the aluminum cover is connected to the second rotating rod via a connector and is in an open state, that is, the aluminum cover does not cover the polyurethane feeding trough. When the rod is transferred to the polyurethane feeding trough, the drive device outputs power to drive the second rotating rod to rotate, and the second rotating rod drives the connector and the aluminum cover to rotate. The aluminum cover gradually approaches the aluminum feeding guide rail and eventually covers the polyurethane feeding trough, completing the cover. At this point, the polyurethane feeding trough is closed, effectively preventing the ingress of debris and protecting the polyurethane feeding trough and other materials. At the same time, the aluminum cover can also be opened by rotating the second rotating rod in the opposite direction.

[0019] Optionally, the driving device includes a third driving mechanism, the third driving mechanism includes a connecting rod and a second driving block, one end of the connecting rod is fixedly connected to the first driving block, the other end of the connecting rod is fixedly connected to the second driving block, and the second driving block is provided with a second driving inclined surface; a second bolt is fixedly provided on the second rotating rod, and the nut of the second bolt abuts against the surface of the second driving inclined surface.

[0020] By adopting the above technical solution, the third driving mechanism connects the first driving block and the second driving block through a connecting rod; when the first driving mechanism drives the first sliding rod (and then drives the first driving block) to move in the horizontal direction, this movement will be transmitted to the second driving block through the connecting rod; the second driving inclined surface opened on the second driving block contacts the nut of the second bolt fixedly set on the second rotating rod; as the second driving block moves, the nut of the second bolt will slide along the inclined surface of the second driving inclined surface; due to the angle of the inclined surface and the fixed position of the bolt, the sliding of the nut on the inclined surface will cause the second rotating rod to be subjected to a torque perpendicular to the axis of the second rotating rod, and this torque will drive the second rotating rod to rotate around its axis; as the second rotating rod rotates, the aluminum cover plate connected to the second rotating rod (through the connecting piece) will move accordingly, thereby realizing the closing or opening operation of the aluminum cover plate; the third driving mechanism enables the movement of the first driving mechanism to indirectly drive the rotation of the second rotating rod, thereby realizing the linkage between multiple moving parts and improving the overall coordination and functionality of the equipment.

[0021] Optionally, a limiting device is provided on the storage rack, and the limiting device includes a sleeve and a top cover bolt. The sleeve is fixed on the storage rack, and the top cover bolt is threadedly engaged with the sleeve; when the aluminum cover is opened, the aluminum cover will abut against the end of the top cover bolt.

[0022] By adopting the above technical solution, the position of the top cover bolt in the sleeve can be adjusted by rotating it, thereby changing the relative distance between the end of the top cover bolt and the aluminum cover plate; this adjustment capability enables the limit device to adapt to aluminum cover plates of different sizes or different limit requirements; when the aluminum cover plate moves to the position abutting the end of the top cover bolt, due to the stability of the threaded connection and the blocking effect of the top cover bolt, the aluminum cover plate will not be able to continue to move in the original direction, thereby achieving the limitation of the position of the aluminum cover plate.

[0023] Optionally, the feeding device also includes a feeding mechanism and a fourth driving mechanism, the feeding mechanism including a driving sprocket, a driven sprocket, a chain, a connecting block, and a feeding rod, the driving sprocket is rotatably connected to the frame, the driven sprocket is rotatably connected to the frame, the chain is arranged around the driving sprocket and the driven sprocket, the driving sprocket and the chain are meshed with each other, and the driven sprocket and the chain are meshed with each other; the connecting block is fixed on the chain, the feeding rod is fixed on the connecting block, one end of the feeding rod is fixed to the connecting block, and the other end of the feeding rod is fixed to the clamping portion; the fourth driving mechanism is arranged on the frame, and the fourth driving mechanism is used to drive the driving sprocket to rotate.

[0024] By adopting the above technical solution, the chain is wrapped around and meshed between the two sprockets, forming a closed-loop transmission system; when the fourth drive mechanism is started, it will output power to drive the active sprocket to rotate. Since the chain and the driven sprocket are also meshed with each other, the driven sprocket will passively rotate with the movement of the chain, thereby maintaining the continuity and stability of the chain; the connecting block is fixedly mounted on the chain and moves with the movement of the chain; since the feeding rod is fixedly connected to the connecting block, the feeding rod will also move along a predetermined trajectory with the movement of the chain, and the feeding rod will drive the clamping part and the bar to move along a predetermined path, thereby realizing the delivery of the bar to the machine tool for processing.

[0025] Optionally, the fourth driving mechanism includes a first motor, a driving gear and a driven gear, the first motor is fixed on the frame, the driving gear is sleeved on the output shaft of the first motor and fixedly connected to the output shaft of the first motor, the driven gear is fixed on one side of the driving sprocket, the driven gear is coaxial with the driving sprocket, and the driving gear and the driven gear are engaged with each other.

[0026] By adopting the above technical solution, when the first motor rotates, the driving gear will also rotate accordingly. As the driving gear rotates, it will transmit the rotational power to the driven gear through meshing. Since the driven gear and the driving sprocket are coaxially fixed, the rotation of the driven gear will drive the driving sprocket to rotate together. The driving sprocket and the chain are meshed with each other. Therefore, when the driving sprocket rotates, it will drive the chain to move along a predetermined path. The movement of the chain will then drive the feeding rod and other components connected to the chain to transport the bar.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. First, multiple bars are placed on the unloading device, and the driving device provides power to the unloading device through mechanical linkage to maintain its stable and continuous unloading; the unloading device can ensure that the bars slide into the feeding aluminum guide rail one by one and in an orderly manner; at the same time, the driving device provides power to the clamping device, and the clamping column of the bar is moved by the clamping device, and then the clamping part is pushed toward the direction close to the bar by the feeding device, so that the bar is inserted into the clamping part of the feeding device; finally, the feeding device drives the clamping part and the bar to move in the horizontal direction, so that the end of the bar away from the clamping part is transported to the machine tool for bar processing; when the bar is processed, residual material will be generated, and the residual material is clamped by the clamping device, and then the clamping part is pushed toward the direction away from the clamping device by the feeding device, so that the residual material of the bar and the clamping part are separated from each other, so that the clamping part is convenient for clamping the next bar; by integrating the clamping device and the feeding device, both are controlled by the same driving device at the same time, thereby reducing the cost of the feeder driving device;

[0029] 2. When the action of the clamping device needs to be adjusted, the driving assembly drives the first sliding rod to slide horizontally. The first sliding rod drives the sliding block to slide horizontally. The sliding block simultaneously drives the two abutment columns to move horizontally, thereby driving the two rotating swing plates to rotate around the rotating axis, thereby automatically driving the clamping device to perform clamping and releasing actions in sequence;

[0030] 3. The driving device drives the first rotating rod to rotate, and the first rotating rod drives the linkage part to rotate.

[0042] The following is combined with Figure 1-9 This application is described in further detail.

[0043] The terms used in this application are for the purpose of describing specific embodiments only and are not intended to limit this application. Unless otherwise defined, technical or scientific terms used in this application should have the common meanings understood by those skilled in the art to which this application belongs. The terms "first," "second," and similar terms used in this application do not indicate any order, quantity, or importance, but are simply used to distinguish different components.

[0044] For ease of understanding, in the horizontal direction of this embodiment, the length direction of the frame 1 is defined as the first direction, and the width direction of the frame 1 is defined as the second direction, and the mechanical oil film type bar automatic feeder is described based on this.

[0045] The embodiment of the present application discloses a mechanical oil film type bar automatic feeder. Figure 1The mechanical oil film type bar automatic feeder includes a frame 1, a feeding device 2, an aluminum guide rail device 3, a clamping device 4, a feeding device 5 and a driving device 6. The feeding device 2 is used to store multiple bars at the same time and sequentially transfer the bars to the guide rail device 3, the clamping device 4 is used to clamp the bars in the aluminum guide rail device 3, and the driving device 6 is used to simultaneously drive the feeding action of the feeding device 2 and the clamping action of the clamping device 4.

[0046] Reference Figure 1 and Figure 2 The aluminum guide rail device 3 includes an aluminum guide rail mounting member 31, which is fixed to the top of the frame 1. The length of the aluminum guide rail mounting member 31 is less than the total length of the frame 1. The guide rail mounting member 31 extends along a first direction. A plurality of detachable feeding aluminum guide rails 32 are provided on the aluminum guide rail mounting member 31, and the ends of two adjacent feeding aluminum guide rails 32 abut against each other. Each feeding aluminum guide rail 32 is provided with a polyurethane trough 33 for conveying rods. The feeding channel 33 extends along the first direction, and both ends of the feeding channel 33 are open. It is convenient for staff to replace different feeding aluminum guide rails 32 according to the diameter of the rods to be processed, thereby facilitating the conveyance of rods of different diameters.

[0047] Reference Figure 3 and Figure 4 The unloading device 2 is used to hold multiple rods and sequentially transfer them to the polyurethane trough 33. In this embodiment, the unloading device 2 includes a hopper 21 and a unloading mechanism 22. The hopper 21 is fixed to one side of the frame 1 and is used for rods with diameters between 2 and 25 mm. The hopper 21 is tilted, with the side of the hopper 21 closer to the guide rail assembly 3 being lower. The unloading mechanism 22 is mounted on the hopper 21 and is used to sequentially transfer the rods from the hopper 21 to the aluminum feed rail 32.

[0048] Continue to refer to Figure 3 and Figure 4The unloading mechanism 22 includes a first rotating rod 221, a linkage member 222 and a top material block 223. The first rotating rod 221 extends along the first direction, passes through the storage rack 21 and is rotatably connected to the storage rack 21. In this embodiment, there are multiple linkage members 222, and multiple linkage members 222 are fixed on the first rotating rod 221. There are also multiple top material blocks 223, and the top material blocks 223 correspond one to one with the linkage members 222. The top material block 223 is slidably matched with the storage rack 21, and the end of the linkage member 222 away from the first rotating rod 221 is rotatably connected to the top material block 223. The linkage member 222 drives the top material block 223 to rise and fall when rotating. During the lifting process, the top material block 223 transfers the rod at the bottom of the storage rack 21 from the storage rack 21 to the polyurethane material trough 33. The driving device 6 is used to drive the first rotating rod 221 to rotate. The first rotating rod 221 is driven to rotate by the driving device 6, and the first rotating rod 221 drives the linkage member 222 to rotate. When the linkage member 222 rises, it pushes down the bar at the bottom of the storage rack 21, and the bar rolls to the inside of the feeding channel 33 under the action of its own gravity (combined with Figure 2 ), thereby realizing automatic unloading.

[0049] Reference Figure 4 For each ejection block 223, two guide rods 211 are fixedly mounted on the storage rack 21. The two guide rods 211 are spaced apart in the vertical direction and each guide rod 211 extends in the first direction. Accordingly, each ejection block 223 is provided with a guide groove 224 extending in the vertical direction. The guide groove 224 is closed at both ends, and the length of the guide groove 224 is greater than the distance between the two guide rods 211. The two guide rods 211 pass through the guide grooves 224, and the ejection block 223 slides in engagement with the two guide rods 211. The two guide rods 211 guide the ejection block 223, increasing the stability of the ejection block 223 in its vertical sliding direction, thereby increasing the stability of the ejection block 223 in unloading.

[0050] Reference Figure 1 and Figure 5The clamping device 4 comprises two sets of abutment posts 41 and two sets of rotating arms 42. One set of abutment posts 41 cooperates with one set of rotating arms 42. Each set of rotating arms 42 comprises a rotating swing plate 43, a rotating shaft 44, and a clamping block 45. The driving end of the rotating swing plate 43 is provided with a driving edge for tightly mating with the abutment posts 41. The driving edge is sequentially provided with a first recessed section 46, a raised section 47, and a second recessed section 48. The rotating swing plate 43 is rotatably connected to the rotating shaft 44. The driven end of the rotating swing plate 43 is connected to the clamping block 45, which slides through the sidewall of the residual material collection trough. The driving device 6 is used to drive the two sets of abutment posts 41 to reciprocate, thereby driving the clamping blocks 45 of the two sets of rotating arms 42 to perform a gripping action. The abutment posts 41 apply force to different sections of the driving edge, cooperating with the rotating swing plate 43 to implement the lever principle, thereby enabling the clamping block of the gripping mechanism to clamp and release the bar material. The clamping device 4 further includes a sensor for sensing whether there is a bar or bar remnant.

[0051] Reference Figure 5 Specifically, the rotating swing plate 43 is rotatably connected to the rotating shaft 44 to form a lever structure. By moving the abutment column 41 and closely contacting different sections of the driving edge, the lever principle is used to drive the clamping block 45 connected to the rotating swing plate 43 to perform the corresponding grasping action or release. Furthermore, a first inclined surface section 49 is provided between the first recessed section 46 and the raised section 47, and a second inclined surface section 50 is provided between the raised section 47 and the second recessed section 48. The slope of the first inclined surface section 49 is smaller than the slope of the second inclined surface section 50. The arrangement of the first inclined surface section 49 and the second inclined surface section 50 allows the abutment column 41 to move more smoothly when switching between different positions of the abutment driving edge. The driving device 6 includes a first driving mechanism 61, which is used to drive the feeding mechanism to perform the material pushing action and to drive the gripping mechanism to perform the gripping action or release action.

[0052] Continue to refer to Figure 5 Specifically, the first driving mechanism 61 includes a sliding assembly 611 and a driving assembly 612. The sliding assembly 611 includes a first sliding rod 6111 and a sliding block 6112. The first sliding rod 6111 slides with the frame 1, and the driving assembly 612 is used to drive the first sliding rod 6111 to slide in the horizontal direction. The sliding block 6112 is fixed on the first sliding rod 6111, and the two abutting columns 41 are both fixed on the sliding block 6112. When it is necessary to adjust the action of the clamping device 4, the first sliding rod 6111 is driven to slide in the horizontal direction by the driving assembly 612. The first sliding rod 6111 drives the sliding block 6112 to slide in the horizontal direction. The sliding block 6112 simultaneously drives the two abutting columns 41 to move in the horizontal direction, thereby driving the two rotating swing plates 43 to rotate around the rotating shaft 44, thereby automatically driving the clamping device 4 to realize the clamping action and the releasing action in sequence.

[0053] Continue to refer to Figure 5 Specifically, the drive assembly 612 includes a second motor 6121, a drive gear 6122, and a rack 6123. The second motor 6121 is fixed to the upper surface of the frame 1 and extends in the second direction. The drive gear 6122 is sleeved on the output shaft of the second motor 6121 and is fixedly connected to the output shaft of the second motor 6121. The rack 6123 extends in the first direction and slides with the frame 1. The sidewall of the rack 6123 abuts the sidewall of the first sliding rod 6111, and the rack 6123 is fixedly connected to the first sliding rod 6111. The rack 6123 is located between the frame 1 and the drive gear 6122, and the drive gear 6122 and the rack 6123 are meshed with each other. The second motor 6121 drives the drive gear 6122 to rotate. When the drive gear 6122 rotates, it drives the rack 6123 to slide in the first direction, thereby facilitating the first sliding rod 6111 to slide in the first direction.

[0054] Reference Figure 5 and Figure 6 The drive device 6 also includes a second drive mechanism 62, which includes a first drive block 621 and a second sliding rod 622. The second sliding rod 622 is fixedly connected to the sliding block 6112, and the second sliding rod 622 is fixedly connected to the first drive block 621. The first drive block 621 is provided with a first drive inclined surface 623. A first connecting block 226 is fixedly provided on the first rotating rod 221. A first bolt 225 is threadedly engaged with the first connecting block 226. The axis of the first bolt 225 and the axis of the first rotating rod 221 are mutually perpendicular. The nut of the first bolt 225 abuts the surface of the first drive inclined surface 623. A first bearing 225 is fixedly provided on the first rotating rod 221. The axis of the first bearing 225 and the axis of the first rotating rod 221 are mutually perpendicular. The nut of the first bearing 225 abuts the surface of the first drive inclined surface 623.

[0055] Continue to refer to Figure 5 and Figure 6When the first drive mechanism 61 drives the first sliding rod 6111 to move horizontally, the first sliding rod 6111 drives the sliding block 6112 to move horizontally, thereby driving the clamping device 4 to perform a corresponding operation, such as clamping or loosening the material. At the same time, because the second sliding rod 622 is fixedly connected to the sliding block 6112, the movement of the sliding block 6112 also drives the second sliding rod 622 to move in the same horizontal direction. The movement of the second sliding rod 622 is further transmitted to the first driving block 621 to which it is fixed, causing the first driving block 621 to also move horizontally. As the first driving block 621 moves horizontally, the nut of the first bolt 225 slides along the inclined surface of the first driving inclined surface 623. Due to the angle of the inclined surface and the fixed position of the bolt, this sliding motion causes the first rotating rod 221 to be subjected to a torque perpendicular to the axis of the first rotating rod 221. This torque drives the first rotating rod 221 to rotate around its axis, thereby driving the unloading mechanism 22 to unload the material, thereby automatically transferring the bar at the bottom of the storage rack 21 to the feeding channel 33.

[0056] Reference Figure 1 and Figure 7 The feeding device 5 includes a clamping portion 51 for clamping the bar, and the feeding device 5 is used to drive the clamping portion 51 to move along the length direction of the frame 1. The feeding device 5 also includes a feeding mechanism 52 and a fourth driving mechanism 53. The feeding mechanism 52 includes a driving sprocket 521, a driven sprocket 522, a chain 523, a connecting block 524, and a feeding rod 525. The driving sprocket 521 is rotatably connected to the frame 1, and the driven sprocket 522 is rotatably connected to the frame 1. The chain 523 is arranged around the driving sprocket 521 and the driven sprocket 522. The driving sprocket 521 and the chain 523 are engaged with each other, and the driven sprocket 522 and the chain 523 are engaged with each other; the connecting block 524 is fixed on the chain 523, and the feeding rod 525 is fixed on the connecting block 524. One end of the feeding rod 525 is fixed to the connecting block 524, and the other end of the feeding rod 525 is fixed to the clamping portion 51, and the feeding rod 525 is penetrated into the feeding channel 33, and the feeding rod 525 slides with the feeding aluminum guide rail 32. The fourth driving mechanism 53 is disposed on the frame 1 and is used to drive the driving sprocket 521 to rotate.

[0057] Reference Figure 7When the fourth driving mechanism 53 is started, it will output power to drive the driving sprocket 521 to rotate. Since the chain 523 and the driven sprocket 522 are also engaged with each other, the driven sprocket 522 will passively rotate with the movement of the chain 523, thereby maintaining the continuity and stability of the chain 523; the connecting block 524 is fixedly mounted on the chain 523 and moves with the movement of the chain 523; since the feeding rod 525 is fixedly connected to the connecting block 524, the feeding rod 525 will also move along a predetermined trajectory with the movement of the chain 523, and the feeding rod 525 will drive the clamping part 51 and the bar to move along a predetermined path, thereby realizing the delivery of the bar to the machine tool for processing.

[0058] Continue to refer to Figure 7 The fourth driving mechanism 53 includes a first motor 531, a driving gear 532 and a driven gear 533. The first motor 531 is fixed to the frame 1. The driving gear 532 is sleeved on the output shaft of the first motor 531 and fixedly connected to the output shaft of the first motor 531. The driven gear 533 is fixed to one side of the driving sprocket 521. The driven gear 533 is coaxial with the driving sprocket 521, and the driving gear 532 and the driven gear 533 are engaged with each other. When the first motor 531 rotates, the driving gear 532 will also rotate accordingly. As the driving gear 532 rotates, it will transmit the rotational power to the driven gear 533 through meshing. Since the driven gear 533 is coaxially fixed with the driving sprocket 521, the rotation of the driven gear 533 will drive the driving chain to rotate together. The driving sprocket 521 and the chain 523 are meshed with each other. Therefore, when the driving sprocket 521 rotates, it will drive the chain 523 to move along a predetermined path. The movement of the chain 523 will then drive the feeding rod 525 and other components connected to the chain 523 to transport the bar.

[0059] Continue to refer to Figure 7 In this embodiment, both the driving gear 532 and the driven gear 533 are helical gears, and the diameter of the driving gear 532 is smaller than that of the driven gear 533. The design of helical gears has a better overlap when meshing than that of spur gears. Since the diameter of the driving gear 532 is smaller than that of the driven gear 533, this design naturally forms a reduction transmission ratio. Reduction transmission helps to increase the output torque while maintaining the output power unchanged, which is particularly important for feeders that require stable and high-torque transmission.

[0060] Reference Figure 1 and Figure 8The unloading device 2 is provided with a covering device 7 for covering the aluminum feed guide rail 32. The covering device 7 includes an aluminum cover plate 71, a connecting member 72, and a second rotating rod 73. The second rotating rod 73 extends along the first direction and is rotatably connected to the storage rack 21. In this embodiment, there are multiple connecting members 72, one end of each connecting member 72 is fixedly connected to the second rotating rod 73, and the other end of each connecting member 72 is fixedly connected to the aluminum cover plate 71.

[0061] Reference Figure 6 and Figure 8 The drive device 6 also includes a third drive mechanism 63, which is used to drive the second rotating rod 73 to rotate. During the unloading process, the aluminum cover 71 is connected to the second rotating rod 73 through the connecting piece 72 and is in an open state, that is, the aluminum cover 71 does not cover the feeding aluminum guide rail 32; when the bar is transferred to the feeding channel 33, the drive device 6 outputs power to drive the second rotating rod 73 to rotate, and the second rotating rod 73 drives the connecting piece 72 and the aluminum cover 71 to rotate. The aluminum cover 71 gradually approaches the feeding aluminum guide rail 32 and eventually covers the feeding aluminum guide rail 32 to achieve the cover. At this time, the feeding aluminum guide rail 32 is closed, which can effectively prevent dust, debris, etc. from entering, protecting the guide rail and the material thereon; at the same time, the aluminum cover 71 can also be opened by rotating the second rotating rod 73 in the opposite direction.

[0062] Reference Figure 5 and Figure 6 Specifically, the third drive mechanism 63 includes a connecting rod 631 and a second drive block 632. Specifically, there are two connecting rods 631, each extending in the second direction. One end of each connecting rod 631 is fixedly connected to the first drive block 621, and the other end of each connecting rod 631 is fixedly connected to the second drive block 632. The second drive block 632 is provided with a second drive inclined surface 633. A second connecting block 731 is fixedly provided on the second rotating rod 73. A second bolt 732 is threadedly engaged with the second connecting block 731, and the nut of the second bolt 732 abuts against the surface of the second drive inclined surface 633.

[0063] Reference Figure 6 and Figure 8, the third driving mechanism 63 connects the first driving block 621 and the second driving block 632 through the connecting rod 631; when the first driving mechanism 61 drives the first sliding rod 6111 (and then drives the first driving block 621) to move in the horizontal direction, this movement is transmitted to the second driving block 632 through the connecting rod 631; the second driving inclined surface 633 provided on the second driving block 632 contacts the nut of the second bolt 732 fixedly provided on the second rotating rod 73; as the second driving block 632 moves, the nut of the second bolt 732 slides along the inclined surface of the second driving inclined surface 633; ​​due to the angle of the inclined surface and the fixed position of the bolt, the sliding of the nut on the inclined surface will cause the second rotating rod 73 to be subjected to a torque perpendicular to the axis of the second rotating rod 73, and this torque will drive the second rotating rod 73 to rotate around its axis; as the second rotating rod 73 rotates, the aluminum cover plate 71 connected to the second rotating rod 73 (through the connecting piece 72) will move accordingly, thereby realizing the covering or opening operation of the feeding aluminum guide rail 32; the third driving mechanism 63 enables the movement of the first driving mechanism 61 to indirectly drive the rotation of the second rotating rod 73, thereby realizing the linkage between multiple moving parts and improving the overall coordination and functionality of the equipment.

[0064] Reference Figure 8 A limiting device 8 is provided on the storage rack 21. The limiting device 8 includes a sleeve 81 and a top cover bolt 82. The sleeve 81 is sleeved on the second rotating rod 73 and fixedly connected to the second rotating rod 73. The top cover bolt 82 is threadedly engaged with the sleeve 81. When the aluminum cover 71 is opened, the aluminum cover 71 will abut against the end of the top cover bolt 82. By rotating the top cover bolt 82, its position in the sleeve 81 can be adjusted, thereby changing the relative distance between the end of the top cover bolt 82 and the aluminum cover 71; this adjustment capability enables the limiting device 8 to adapt to aluminum cover plates 71 of different sizes or different limiting requirements; when the aluminum cover 71 moves to a position abutting against the end of the top cover bolt 82, due to the stability of the threaded connection and the blocking effect of the top cover bolt 82, the aluminum cover 71 will not be able to continue to move in the original direction, thereby achieving a limit on the position of the aluminum cover 71.

[0065] Reference Figure 9A support block 11 is provided at the end of the shock absorber, and a through hole is provided on the support block 11 for the rod to pass through. At the same time, a clamping assembly 9 is also provided on the side wall of the support block 11. The specific clamping assembly 9 includes a clamping cylinder 91. The clamping cylinder 91 includes a cylinder body and two clamping jaws. The cylinder body is fixed on the support block 11, and the cylinder body is used to drive the two clamping jaws to slide in the direction of approaching or moving away from each other. Two guide wheels 92 are rotatably provided on each clamping jaw, and a space for the rod to pass through is provided between the four guide wheels 92. The clamping cylinder 91 is driven by the cylinder body to quickly and accurately slide the two clamping jaws in the direction of approaching or moving away from each other, thereby achieving efficient clamping and release of the rod and ensuring the stability of the rod during transmission.

[0066] The implementation principle of the above embodiment is as follows: first, a plurality of bars are placed on the unloading device 2, and the driving device 6 provides power to the unloading device 2 through mechanical linkage to maintain its stable and continuous unloading; the unloading device 2 can ensure that the bars slide one by one and orderly into the feeding aluminum guide rail 32; at the same time, the driving device 6 provides power to the clamping device 4, and the clamping column of the bar is moved by the clamping device 4, and then the clamping part 51 is pushed toward the direction close to the bar through the feeding device 5, thereby realizing the insertion of the bar into the clamping part 51 of the feeding device 5; finally, the feeding device 5 drives the clamping The holding portion 51 and the rod move in the horizontal direction, thereby transporting the end of the rod away from the clamping portion 51 to the machine tool for rod processing; when the rod processing is completed, residual material will be generated, and the residual material is clamped by the clamping device 4, and then the clamping portion 51 is pushed by the feeding device 5 to move in the direction away from the clamping device 4, so that the residual material of the rod and the clamping portion 51 are separated from each other, making it easier for the clamping portion 51 to clamp the next rod; by integrating the clamping device 4 and the feeding device 5, both are controlled by the same drive device 6 at the same time, thereby reducing the cost of the feeder drive device 6.

[0067] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
