Description

Technical Field

[0001] This application relates to the field of metal processing technology, and in particular to a tubular metal conveying device. Background Technology

[0002] In the field of mechanical manufacturing and assembly, tubular metal parts such as nuts and threaded sleeves, hollow bushings, etc., are widely used in various mechanical equipment as basic connecting and transmission components. The workpiece is processed by machining equipment through turning, punching, cutting and other operations on the tubular metal parts.

[0003] The processing equipment achieves high-precision machining of tubular metal parts through a precise mechanical structure and CNC system. It can quickly switch processes according to different workpiece requirements. In the entire processing flow, the feeding of tubular metal parts is the key to production continuity.

[0004] Traditional feeding structures often rely on manual operation. Operators need to manually place tubular metal parts one by one into the feed port of the processing equipment. Manual feeding is slow and difficult to match the high-speed processing rhythm of the equipment. At the same time, after processing, excess material needs to be removed manually, resulting in long idle time of the equipment and the phenomenon of feeding position deviation, which affects the quality of the workpiece. Utility Model Content

[0005] The purpose of this application is to provide a tubular metal part conveying device to solve the problem of low efficiency of manual feeding and the impact on workpiece processing efficiency mentioned in the background art.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] A tubular metal part conveying device includes a support plate, an mounting plate fixed to the upper end of the support plate, a conveying groove formed on the mounting plate, a conveying chain mounted on the mounting plate, the conveying chain being driven by a servo motor, a conveying pipe slidably disposed inside the conveying groove, a connecting plate fixed to the conveying pipe, the side of the connecting plate away from the conveying pipe being fixedly connected to the conveying chain, an installation housing fixed to one end of the support plate, a support leg fixed to the lower end of the support plate, and a clamping structure and a feeding structure provided on the support plate.

[0008] By adopting the above technical solution, during use, the tubular metal part is fed into the conveying trough using the feeding structure. Then, the conveying chain drives the conveying pipe to move, and the clamping structure allows the tubular metal part to enter the conveying pipe. After that, the conveying chain drives the conveying pipe and the tubular metal part to move, sending the tubular metal part into the processing equipment for processing.

[0009] Furthermore, the clamping structure includes a mounting base fixed to the mounting plate, a driving plate slidably disposed on the side of the mounting base, a first inclined surface and a second inclined surface being provided on the driving plate, two mounting bases being provided and symmetrically arranged, a support block being fixed to the side of the mounting base, and the driving plate being hinged to the support block.

[0010] By adopting the above technical solution, the clamping structure can be used to clamp the tubular metal parts, thereby cooperating with the conveying pipe to separate and connect the tubular metal parts from the conveying pipe, thus facilitating the conveying of the tubular metal parts.

[0011] Furthermore, two symmetrically arranged first telescopic cylinders are fixed inside the mounting housing. The telescopic ends of the first telescopic cylinders are rotatably connected to moving wheels. A connecting block is hinged to one end of the drive plate near the mounting base. A sliding shaft is fixed to the side of the connecting block. A clamping block is fixed to one end of the sliding shaft away from the connecting block. An active groove adapted to the sliding shaft and clamping block is opened inside the mounting base.

[0012] By adopting the above technical solution, the extension or retraction of the first telescopic cylinder can drive the moving wheel to slide inside the first and second inclined surfaces, causing the drive plate to be squeezed. When the drive plate is squeezed by the moving wheel, it will squeeze the connecting block, and the connecting block will squeeze the sliding column, causing the clamping block to extend out of the mounting seat. The tubular metal part is clamped by the two clamping blocks, and the conveying chain drives the conveying pipe to separate or connect the tubular metal part from the conveying pipe, so as to achieve clamping or releasing the tubular metal part.

[0013] Furthermore, a return spring is slidably sleeved on the sliding shaft, and the two ends of the return spring are fixedly connected to the mounting base and the connecting block, respectively.

[0014] By adopting the above technical solution, the return spring is squeezed when the sliding shaft slides into the movable groove. When the sliding column is no longer squeezed, the return spring plays the role of resetting.

[0015] Furthermore, a feeding trough is provided on the support plate, and a collection box is slidably connected to the lower end of the support plate at a position corresponding to the feeding trough.

[0016] By adopting the above technical solution, the feeding trough and the collection box can collect the remaining tubular metal parts inside the conveying pipe after processing, so as to facilitate subsequent reuse.

[0017] Furthermore, the feeding structure includes a feeding plate fixed on the support plate, with several support bars fixed at the upper end of the feeding plate and several limiting blocks fixed on the side of the feeding plate.

[0018] By adopting the above technical solution, after the tubular metal tubes remaining inside the conveying pipe are removed, the new tubular metal tubes can be automatically fed into the conveying trough through the feeding structure, thereby realizing automatic feeding, improving feeding efficiency, and making it more conducive to subsequent processing of the workpieces.

[0019] Furthermore, an installation strip is installed on the side of the feeding plate, and a top material block is fixed at the upper end of the installation strip. The top material block is slidably disposed between the feeding plate and the limiting block.

[0020] By adopting the above technical solution, the installation strip drives multiple top blocks to lift the tubular metal tube that falls on the top blocks, so that it falls into the conveying trough along the limit block, thus completing the feeding.

[0021] Furthermore, a second telescopic cylinder is fixed to the upper end of the support plate, and the telescopic end of the second telescopic cylinder is fixedly connected to the mounting strip.

[0022] By adopting the above technical solution, the extension or retraction of the extension end of the second telescopic cylinder can provide power for the top material plate to push the material.

[0023] In summary, this application includes at least one of the following beneficial effects;

[0024] 1. In this application, when the tubular metal part is fed into the processing equipment using the conveying device, the tubular metal part is automatically fed into the processing equipment through the feeding structure. Then, the conveying chain drives the conveying pipe to move, and with the help of the clamping structure, the tubular metal part enters into the conveying pipe. After that, the conveying chain drives the conveying pipe and the tubular metal part to move, feeding the tubular metal part into the processing equipment to complete the processing. When the processing is completed, the conveying bar moves back with the conveying pipe and the remaining tubular metal part. Then, with the help of the clamping structure, the remaining tubular metal part is taken out, and the feeding structure is used to feed it again. The above operation is repeated to complete the processing of the tubular metal part. This conveying device utilizes a fully automated feeding structure, significantly reducing manual operation and greatly improving feeding efficiency. The clamping structure works in conjunction with the conveyor chain, conveyor pipe, and other structures to achieve precise docking between the metal parts to be processed and the conveyor pipe, as well as automatic separation of remaining material heads, effectively reducing the intensity of manual labor. Furthermore, by using the conveyor chain in conjunction with the conveyor pipe and other structures to transport tubular metal parts, it enables precise docking between the tubular metal parts and the processing equipment. The entire processing process does not require operators to control the entry and exit of the tubular metal parts. By optimizing the conveying process, not only is the conveying efficiency of tubular metal parts improved, but the overall processing efficiency of the workpiece is also enhanced.

[0032] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0033] This application discloses a tubular metal component conveying device.

[0034] Reference Figure 1 and Figure 2 A tubular metal part conveying device includes a support plate 1, an mounting plate 11 fixed to the upper end of the support plate 1, a conveying groove 12 opened on the mounting plate 11, a conveying chain 13 mounted on the mounting plate 11, the conveying chain 13 being driven by a servo motor, a conveying pipe 14 slidably arranged inside the conveying groove 12, a connecting plate 15 fixed on the conveying pipe 14, the side of the connecting plate 15 away from the conveying pipe 14 being fixedly connected to the conveying chain 13, an mounting housing 16 fixed to one end of the support plate 1, a support leg 17 fixed to the lower end of the support plate 1, and a clamping structure and a feeding structure provided on the support plate 1.

[0035] In use, the feeding structure feeds the tubular metal part into the processing equipment. Then, the conveyor chain 13 drives the conveyor pipe 14 to move, and with the help of the clamping structure, the tubular metal part enters the conveyor pipe 14. After that, the conveyor chain 13 drives the conveyor pipe 14 and the tubular metal part to move, feeding the tubular metal part into the processing equipment for processing. After processing is completed, the conveyor bar moves back with the conveyor pipe 14 and the remaining tubular metal part. Then, with the help of the clamping structure, the remaining tubular metal part is taken out, and the feeding structure feeds it again. The above operation is repeated to process the tubular metal part.

[0036] Reference Figures 2-4 The clamping structure includes a mounting base 2 fixed on the mounting plate 11. A drive plate 21 is slidably arranged on the side of the mounting base 2. A first inclined surface 211 and a second inclined surface 212 are provided on the drive plate 21. There are two mounting bases 2 arranged symmetrically. A support block 24 is fixed on the side of the mounting base 2. The drive plate 21 is hinged to the support block 24.

[0037] The mounting housing 16 has two symmetrically arranged first telescopic cylinders 22 fixed inside. The telescopic end of the first telescopic cylinder 22 is rotatably connected to a moving wheel 23. The drive plate 21 is hinged to a connecting block 25 at one end near the mounting base 2. A sliding shaft 251 is fixed to the side of the connecting block 25. A clamping block 252 is fixed to the end of the sliding shaft 251 away from the connecting block 25. The mounting base 2 has an active groove 253 inside that is adapted to the sliding shaft 251 and the clamping block 252.

[0038] In addition, a return spring 254 is slidably sleeved on the sliding shaft 251, and the two ends of the return spring 254 are fixedly connected to the mounting base 2 and the connecting block 25, respectively.

[0039] Furthermore, a feeding trough 26 is provided on the support plate 1, and a collection box 261 is slidably connected to the lower end of the support plate 1 at a position corresponding to the feeding trough 26.

[0040] When the tubular metal workpiece inside the conveying trough 12 needs to be fed into the processing equipment, the telescopic ends of the two first telescopic cylinders 22 on both sides of the mounting plate 11 extend, driving the moving wheel 23 to move inside the second inclined surface 212. As the moving wheel 23 moves, the drive plate 21 gradually receives force and rotates around its hinge point with the support block 24. At this time, the connecting block 25 at the end of the drive plate 21 moves under force to squeeze the return spring 254 and push the sliding shaft 251 to move inside the movable groove 253. The movement of the sliding shaft 251 pushes the clamping block 252 to move, clamping the tubular metal workpiece through the two clamping blocks 252. At this time, the moving wheel 23 is located between the first inclined surface 211 and the second inclined surface 212 on the drive plate 21. Then the telescopic ends of the first telescopic cylinders 22 stop extending, and then the conveying chain 13 drives the conveying pipe 14 to move slowly, so that the pipe... The tubular metal workpiece enters the conveying pipe 14. The friction between the conveying pipe 14 and the tubular metal workpiece connects the two parts. After connection, the conveying chain 13 stops moving. Then, the telescopic end of the first telescopic cylinder 22 continues to extend, driving the moving wheel 23 into the first inclined surface 211. At this time, the drive plate 21 is no longer subjected to resistance. Under the action of the return spring 254, the drive plate 21, connecting block 25, sliding shaft 251, and clamping block 252 are reset and no longer clamp the tubular metal workpiece. Then, the conveying chain 13 moves again, driving the conveying pipe 14 and the tubular metal workpiece to move inside the conveying groove 12 until its end enters the processing equipment. As the processing equipment processes the tubular metal workpiece, the tubular metal workpiece gradually shortens. The conveying chain 13 drives the tubular metal workpiece to move, so that the tubular metal workpiece gradually enters the processing equipment.

[0041] As the tubular metal part gradually shortens, when it reaches a length insufficient for processing, the conveyor chain 13 moves in the reverse direction, driving the conveyor pipe 14 and the remaining tubular metal part to move. When the remaining tubular metal part is between the two clamping blocks 252, the conveyor chain 13 stops moving. At this time, the telescopic end of the first telescopic cylinder 22 begins to retract. During the retraction, the drive plate 21 is subjected to force, causing the two clamping blocks 252 to extend out of the mounting base 2 and clamp the remaining tubular metal part. At this time, the moving wheel 23 is located between the first inclined surface 211 and the second inclined surface 212 on the drive plate 21. Then, the telescopic end of the first telescopic cylinder 22 stops retracting, clamping the remaining tubular metal part. The conveyor chain 13 continues to move back, separating the conveyor pipe 14 from the remaining tubular metal part. After separation, the conveyor chain 13 stops moving. Then, the telescopic end of the first starting telescopic rod continues to retract, causing the rolling wheel to enter the second movable groove 253. At this time, the drive plate 21 is no longer subjected to resistance and then resets under the action of the return spring 254. The tubular metal part separated from the conveyor pipe 14 falls into the collection box 261 through the unloading groove 26 for reuse. Then, the tubular metal part to be processed is fed into the conveying groove 12 through the feeding structure, and the above operation is repeated. Through the clamping structure in conjunction with the conveyor chain 13, conveyor pipe 14 and other structures, automatic feeding can be achieved with high feeding efficiency. It can also automatically unload the remaining tubular metal part, which can be removed and clamped and conveyed again for the tubular metal part to be processed, improving the processing efficiency of the workpiece.

[0042] Reference Figure 1 , Figure 2 , Figure 5 The feeding structure includes a feeding plate 3 fixed on a support plate 1. The feeding plate 3 is inclined. Several support bars 31 are fixed on the upper end of the feeding plate 3. Several limiting blocks 32 are fixed on the side of the feeding plate 3. The limiting blocks 32 are inclined and face the conveying trough 12 from high to low.

[0043] The feeding plate 3 has an installation strip 33 installed on its side. A top material block 331 is fixed to the upper end of the installation strip 33. The upper end face of the top material block 331 is flush with the upper end face of the support strip 31. The top material block 331 is slidably disposed between the feeding plate 3 and the feeding plate 3. The top material block 331 is located on the side of the limiting block 32. When multiple tubular metal parts are placed on the feeding plate 3, one tubular metal part that is in contact with the limiting block 32 is located above the top material block 331.

[0044] In addition, a second telescopic cylinder 332 is fixed to the upper end of the support plate 1, and the telescopic end of the second telescopic cylinder 332 is fixedly connected to the mounting strip 33.

[0045] In use, multiple tubular metal parts are placed on the feeding plate 3 and supported by the support bar 31. After the remaining tubular metal part after processing the previous one is separated from the conveying pipe 14, the extension end of the second telescopic cylinder 332 extends, driving the mounting bar 33 to rise. The rise of the mounting bar 33 drives multiple top material blocks 331 to rise. During the rise of the top material blocks 331, a tubular metal part to be processed is lifted up. When the upper end of the top material block 331 is flush with the upper end of the limiting block 32, the lifted tubular metal part will roll along the upper end surface of the limiting block 32 and fall into the conveying groove 12, realizing automatic feeding. Afterwards, the extension end of the second telescopic cylinder 332 retracts, making the upper end surface of the top material block 331 flush with the upper end surface of the support bar 31. At this time, the tubular metal parts on the support bar 31 will roll, and one of the tubular metal parts will fall onto the upper end surface of the top material block 331 for the next feeding. The feeding structure enables automatic feeding, reducing manual intervention. Combined with the conveyor chain 13, conveyor pipe 14, and clamping structure, it enables automatic loading and unloading of tubular metal parts, thereby improving the processing efficiency of workpieces.

[0046] Working principle: When using this conveying device to transport tubular metal parts into the processing equipment for processing, multiple tubular metal parts are placed on the feeding plate 3, and the support bars 31 support the tubular metal parts. During feeding, the extension end of the second telescopic cylinder 332 extends, driving the mounting bar 33 to rise. The rise of the mounting bar 33 drives multiple top material blocks 331 to rise. During the rise of the top material blocks 331, one of the tubular metal parts to be processed, which is in contact with the limiting block 32 and located above the top material blocks 331, is lifted up. When the upper end of block 331 is flush with the upper end of limit block 32, the lifted tubular metal part will roll along the upper surface of limit block 32 and fall into the conveying groove 12 to achieve automatic feeding. Then the telescopic end of the second telescopic cylinder 332 retracts, so that the upper surface of the top material block 331 is flush with the upper surface of the support bar 31. At this time, the tubular metal part on the support bar 31 rolls along the inclined support bar 31 under the action of gravity, and one of the tubular metal parts will fall on the upper surface of the top material block 331 for the next feeding.

[0047] When the tubular metal part enters the conveying groove 12, the telescopic ends of the two first telescopic cylinders 22 on both sides of the mounting plate 11 extend, driving the moving wheel 23 to move inside the second inclined surface 212. As the moving wheel 23 moves and cooperates with the second inclined surface 212 on the drive 21, the drive plate 21 gradually receives force. After receiving force, the drive plate 21 rotates around its hinge point with the support block 24. At this time, the connecting block 25 at the end of the drive plate 21 moves under force, squeezing the return spring 254 and pushing the sliding shaft 251 to move inside the movable groove 253. The movement of the sliding shaft 251 pushes the clamping block 252 to move, clamping the tubular metal workpiece through the two clamping blocks 252. At this time, the moving wheel 23 is located between the first inclined surface 211 and the second inclined surface 212 on the drive plate 21. Then, the telescopic ends of the first telescopic cylinders 22 stop extending, and then the conveying chain 13 drives the conveying pipe 14 slowly. The slow movement allows the tubular metal workpiece to enter the conveying pipe 14. Utilizing the friction between the conveying pipe 14 and the tubular metal workpiece, they connect. After connection, the conveying chain 13 stops moving. Then, the telescopic end of the first telescopic cylinder 22 continues to extend, driving the moving wheel 23 into the first inclined surface 211. At this point, the drive plate 21 is no longer subjected to resistance. Under the action of the return spring 254, the drive plate 21, connecting block 25, sliding shaft 251, and clamping block 252 reset, ceasing to clamp the tubular metal workpiece. The conveying chain 13 then moves again, driving the conveying pipe 14 and the tubular metal workpiece within the conveying trough 12 until its end enters the processing equipment. As the processing equipment processes the tubular metal workpiece, it gradually shortens. The conveying chain 13 drives the tubular metal workpiece, gradually bringing it into the processing equipment. This fully automated feeding structure significantly reduces manual operation and greatly improves feeding efficiency.

[0048] As the tubular metal part gradually shortens, when it reaches a length insufficient for processing, the conveyor chain 13 moves in the reverse direction, driving the conveyor pipe 14 and the remaining tubular metal part to move. When the remaining tubular metal part is between the two clamping blocks 252, the conveyor chain 13 stops moving. At this time, the telescopic end of the first telescopic cylinder 22 begins to retract. During the retraction, the drive plate 21 is subjected to force, causing the two clamping blocks 252 to extend out of the mounting base 2 and clamp the remaining tubular metal part. At this time, the moving wheel 23 is located between the first inclined surface 211 and the second inclined surface 212 on the drive plate 21. Then, the telescopic end of the first telescopic cylinder 22 stops retracting, clamps the remaining tubular metal parts, and the conveyor chain 13 continues to move back, causing the conveyor pipe 14 to separate from the remaining tubular metal parts. After separation, the conveyor chain 13 stops moving, and then the telescopic end of the first starting telescopic rod continues to retract, causing the rolling wheel to enter the second movable groove 253. At this time, the drive plate 21 is no longer subjected to resistance force, and then resets under the action of the reset spring 254. The tubular metal parts separated from the conveyor pipe 14 fall into the collection box 261 through the discharge groove 26 for reuse.

[0049] Then the second telescopic cylinder 332 works again, driving the top material block 331 to rise and load the material. The above operation is repeated to complete the processing of the tubular metal part.

[0050] The clamping structure works in conjunction with the conveyor chain 13, conveyor pipe 14, and other structures to achieve precise docking between the metal parts to be processed and the conveyor pipe 14, and to automatically separate the remaining material heads, effectively reducing the intensity of manual labor. Furthermore, by using the conveyor chain 13 in conjunction with the conveyor pipe 14 and other structures to transport the tubular metal parts, the tubular metal parts can be precisely docked with the processing equipment. The entire processing process does not require operators to control the entry and exit of the tubular metal parts. By optimizing the conveying process, not only is the conveying efficiency of the tubular metal parts improved, but the overall processing efficiency of the workpiece is also improved.
