Description

A type of anti-torsion tube screw machine Technical Field

[0001] This application relates to the field of screw machine technology, and more particularly to an anti-torsion tube screw machine. Background Technology

[0002] In traditional production lines, screw tightening operations are still predominantly performed manually or semi-automatically. Manual processes rely entirely on human labor for screw alignment, hole calibration, and tightening, resulting in high labor intensity and low efficiency. While semi-automatic processes use electric / pneumatic tools to replace some manual rotational movements, core steps such as precise screw placement and hole alignment still require manual intervention, limiting the potential for overall efficiency improvement. Both processes generally suffer from three significant drawbacks: first, human operation is susceptible to fatigue, leading to unstable screw tightening torque and product quality fluctuations; second, the time-consuming processes constrain capacity increases and are difficult to match the pace of modern production lines; and third, continuously rising labor costs exacerbate operational pressures on businesses.

[0003] More notably, the existing anti-torsion tube uses an L-shaped end connection design, which results in the anti-torsion tube body and the end with the screw hole not being on the same plane. Therefore, it is difficult to reliably fix the end of the anti-torsion tube during the fastening process. This makes the end of the anti-torsion tube prone to mechanical vibration or positioning deviation, leading to a decrease in assembly accuracy. As a result, the entire fastening process is difficult to automate, forcing the production line to revert to manual operation mode, which seriously restricts the improvement of production efficiency and product quality.

Therefore, they should not be construed as limitations on this application.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application.

[0027] Referring to Figures 1, 2, and 3, this application discloses an anti-torsion tube screw-making machine. The anti-torsion tube screw-making machine includes a lower base 1, a locking mechanism 2, and a positioning mechanism 3. In some embodiments, the locking mechanism 2 is mounted on the lower base 1 and is used to lock screws onto the anti-torsion tube; the positioning mechanism 3 includes a positioning base plate 31 and a positioning clamping member 32. The positioning base plate 31 is mounted on the lower base 1, and the positioning clamping member 32 is disposed above the positioning base plate 31, and the positioning clamping member 32 can move up and down relative to the positioning base plate 31 to fix the anti-torsion tube onto the positioning base plate 31. Preferably, by disposing the positioning clamping member 32 above the positioning base plate 31 and allowing the positioning clamping member 32 to move up and down relative to the positioning base plate 31, the end of the anti-torsion tube is fixed onto the positioning base plate 31, ensuring that the end of the anti-torsion tube can be reliably fixed onto the positioning base plate 31 during the locking process, thereby ensuring the assembly accuracy of the locking mechanism 2 and achieving efficient and high-precision automated screw assembly.

[0028] Referring to Figures 1, 2, 3, and 4, in some embodiments, a material transfer mechanism 4 is further included. The material transfer mechanism 4 includes: a material transfer guide rail 41, which is disposed on a material transfer plate 42 on the lower base 1. The material transfer plate 42 is slidably connected to the material transfer guide rail 41. A positioning base plate 31 and a positioning clamping member 32 are both assembled on the material transfer plate 42. A material transfer cylinder 43 is connected to the output end of the material transfer plate 42 and is used to drive the material transfer plate 42 to move in the horizontal direction. In this embodiment, since both the positioning base plate 31 and the positioning clamping member 32 are mounted on the transfer plate 42, the positioning base plate 31 and the positioning clamping member 32 can maintain the fixation of the anti-torsion tube during the transfer process. Thus, after the locking mechanism 2 has finished locking the screw in one of the screw holes of the anti-torsion tube, the transfer plate 42 can be driven by the transfer cylinder 43 to move along the transfer guide rail 41 to align the other screw hole of the anti-torsion tube with the locking mechanism 2. This avoids the problem of low assembly efficiency and reduced assembly accuracy caused by repeated disassembly and assembly of the anti-torsion tube, effectively improving the efficiency of automated screw assembly and reducing errors caused by manual assembly. Optionally, a transfer slider is slidably connected on the transfer guide rail 41, and the transfer plate 42 is fixedly connected to the transfer slider.

[0029] Referring to Figures 3 and 4, in some embodiments, the positioning clamping member 32 includes a positioning frame 321 extending along the height direction. The positioning frame 321 is mounted on the transfer plate 42. A positioning cylinder 322 is mounted on the upper end of the positioning frame 321. The output end of the positioning cylinder 322 is connected to a positioning clamping plate 323, which is disposed opposite to the positioning base plate 31. Preferably, the positioning clamping plate 323 is driven to move up and down relative to the positioning base plate 31 by the positioning cylinder 322, so that the positioning clamping plate 323 and the positioning base plate 31 clamp and fix the anti-torsion tube, ensuring that the end of the anti-torsion tube can be reliably fixed on the positioning base plate 31 during the locking process, thereby ensuring the assembly accuracy of the locking mechanism 2 and realizing efficient and high-precision automated screw assembly.

[0030] Referring to Figures 3 and 4, in some embodiments, the positioning frame 321 is provided with a plurality of positioning plates 324, which are arranged along the height direction. Each positioning plate 324 has a positioning slot 325 for engaging the anti-torsion tube. Thus, the positioning slots 325 in the plurality of positioning plates 324 arranged along the height direction engage and fix the anti-torsion tube, thereby improving the stability of the anti-torsion tube during the locking process. Furthermore, a rotary motor is connected to each positioning plate 324, and a limit stop is connected to the output end of the rotary motor. By rotating the limit stop, the limit stop pushes against the anti-torsion tube and cooperates with the positioning slot 325, pressing the anti-torsion tube tightly into the positioning slot 325.

[0031] Referring to Figures 3 and 4, in some embodiments, the positioning mechanism 3 further includes: a positioning hole 311 disposed on the positioning base plate 31; and an elastic positioning pin 312 disposed in the positioning hole 311 and capable of extending or retracting from the positioning hole 311. When the elastic positioning pin 312 extends out of the positioning hole 311, it is used to engage with the screw hole of the anti-torsion tube. When the screw is locked into the screw hole of the anti-torsion tube, the push of the screw will drive the elastic positioning pin 312 to retract into the positioning hole 311. Preferably, the elastic positioning pin 312 is inserted into the screw hole of the anti-torsion tube from bottom to top, forming a mechanical positioning constraint on the end of the anti-torsion tube. The locking mechanism 2 screws the screw into the screw hole of the anti-torsion tube. As the screw gradually moves down, it pushes against the elastic positioning pin 312, driving the elastic positioning pin 312 to gradually retract into the positioning hole 311. This eliminates interference in the movement of the mechanism and maintains the stability of the product position through a dynamic positioning mechanism.

[0032] Furthermore, the elastic positioning pin 312 includes a fixed cylinder, a spring, and a positioning pin. The fixed cylinder is disposed inside the positioning hole 311, or at the lower end of the positioning base plate 31, and the fixed cylinder has an opening facing upward, which communicates with the positioning hole 311. The spring is assembled inside the fixed cylinder, and the lower end of the positioning pin abuts against the upper end of the spring. In this embodiment, under the elastic force of the spring, the positioning pin extends upward through the positioning hole 311 to be inserted into the screw hole of the anti-torsion tube, forming a mechanical positioning constraint. When the screw is locked into the screw hole of the anti-torsion tube, its pushing force acts on the spring through the positioning pin, causing the spring to compress, thereby driving the positioning pin to retract into the positioning hole 311. This eliminates the interference of the mechanism movement and maintains the stability of the anti-torsion tube position through the dynamic positioning mechanism, effectively solving the quality defects caused by positioning offset in traditional assembly, and realizing efficient and high-precision automated screw assembly.

[0033] Referring to Figures 2, 3, and 4, in some embodiments, the locking mechanism 2 includes: a locking frame 21; a clamping member 22, which is fixed to the locking frame 21 for fixing screws; a bit member 23, which is disposed above the clamping member 22 and can rotate relative to the clamping member 22; and a lifting member 24, which is connected to the bit member 23 for driving the bit member 23 to move up and down, and when the bit member 23 moves down, it is fitted onto the screw to drive the screw to move down and / or drive the screw to rotate. In this way, the screw is pre-fixed on the clamp 22 so that the screw is aligned with the screw hole of the anti-torsion tube. Then, the lifting member 24 drives the bit member 23 to move downward, put the bit member 23 on the screw nut, and drive the screw to move downward. When the screw abuts against the screw hole of the anti-torsion tube, the bit member 23 drives the screw to rotate, so as to lock the screw onto the anti-torsion tube, thereby realizing efficient and high-precision automated screw assembly.

[0034] Referring to Figures 2, 3, and 4, in some embodiments, the clamping member 22 includes a clamping body 221 and a plurality of clamping blocks 222; the clamping body 221 has an inner cavity slide 223 extending through both the upper and lower ends, and the bit member 23 extends into the upper opening of the inner cavity slide 223; the clamping blocks 222 are pivotally connected to the lower opening of the inner cavity slide 223, and when the bit member 23 drives the screw to move downward, it will drive the clamping blocks 222 to rotate outward to open the lower opening of the inner cavity slide 223. Optionally, a number of clamping blocks 222 are arranged circumferentially at the lower opening of the inner cavity slide 223. In this way, the clamping blocks 222 can seal the lower opening of the inner cavity slide 223 to prevent the screw from slipping directly. When the lifting member 24 drives the screw to move downward through the bit member 23, the clamping blocks 222 rotate outward around the pivot axis under the pushing action of the bit member 23 and the screw to open the lower opening of the inner cavity slide 223. In this embodiment, the screw is pre-transported to the inner slide 223. At this time, the lower opening of the inner slide 223 is closed by the clamping block 222 to prevent the screw from slipping directly. Then, the lifting member 24 drives the bit member 23 to move downward along the inner slide 223, so that the bit member 23 is accurately fitted onto the screw nut under the constraint of the inner slide 223, and drives the screw to move downward, so as to drive the clamping block 222 to rotate outward and open the lower opening of the inner slide 223. When the screw abuts against the screw hole of the anti-torsion tube, the bit member 23 drives the screw to rotate, so as to lock the screw onto the anti-torsion tube, thereby realizing efficient and high-precision automated screw assembly.

[0035] Referring to Figures 2, 3, and 4, in some embodiments, a feeding mechanism 5 is further included. The feeding mechanism 5 includes a storage bin 51, a distributing guide rail 52, and a feeding conduit 53. The storage bin 51 has a storage cavity, in which a roller is disposed. The roller can rotate relative to the storage bin 51 to arrange screws in a specific posture on the distributing guide rail 52. One end of the distributing guide rail 52 extends into the storage cavity, and the other end of the distributing guide rail 52 is connected to the input end of the feeding conduit 53 to convey the screws to the feeding conduit 53. The output end of the feeding conduit 53 is connected to the inner cavity slide 223 to convey the screws to the inner cavity slide 223. Preferably, the screws are pre-stored in the storage bin 51. During feeding, a roller rotates within the storage chamber, causing the screws to rotate to a high position. Then, under the influence of gravity, the screws fall onto the distribution guide rail 52, allowing screws with specific postures to be arranged on the distribution guide rail 52. The distribution guide rail 52 then transports the screws to the input end of the feeding conduit 53. Optionally, a distribution cylinder is provided at the output end of the distribution guide rail 52. The distribution cylinder pushes the screws from the output end of the distribution guide rail 52 one by one into the feeding conduit 53. Then, air is blown into the screws in the feeding conduit 53 to transport them into the inner cavity slide 223, thus achieving fully automatic feeding and further improving the efficiency of automated screw assembly. Optionally, the feeding conduit 53 is blown by an air pump. Optionally, an oil-water separator is provided between the air pump and the feeding conduit 53 to filter moisture from the air.

[0036] Referring to Figures 3 and 4, in some embodiments, the bit component 23 includes a bit sleeve 231 extending into the upper opening of the inner cavity slide 223. The upper end of the bit sleeve 231 is connected to a first transmission link 232, and the upper end of the first transmission link 232 is connected to a rotary motor 233, which is fixedly connected to the lifting component 24. Optionally, the lower end of the bit sleeve 231 is provided with a bit groove, the shape of which matches the nut of the screw. Thus, after the bit sleeve 231 is fitted onto the screw, it can drive the screw to rotate, thereby securing the screw to the anti-torsion tube. In this embodiment, the lifting component 24 drives the rotary motor 233 to move up and down, which in turn drives the bit sleeve 231 to move up and down via the first transmission link 232. Thus, during assembly, the lifting component 24 drives the rotary motor 233 to move down, which in turn drives the bit sleeve 231 to move down via the first transmission link 232. This allows the bit 23 to be fitted onto the screw nut and causes the screw to move down. When the screw abuts against the screw hole of the anti-torsion tube, the rotary motor 233 drives the bit sleeve 231 to rotate via the first transmission link 232, causing the bit sleeve 231 to drive the screw to rotate and lock the screw onto the anti-torsion tube, thereby achieving efficient and high-precision automated screw assembly.

[0037] Referring to Figures 2, 3, and 4, in some embodiments, the lifting component 24 includes a lifting cylinder 241, a second transmission link 242, and a lifting platform 243. The output end of the lifting cylinder 241 is connected to the second transmission link 242, the second transmission link 242 is connected to the lifting platform 243, and the lifting platform 243 is connected to the bit assembly 23. Thus, the lifting cylinder 241 converts linear thrust into vertical movement of the first lifting platform via the second transmission link 242, thereby driving the bit assembly 23 mounted on the lifting platform to move vertically synchronously. Optionally, the lifting component 24 also includes a guide post extending along the height direction. The lifting platform 243 is slidably connected to the guide post, using the guide post to constrain the movement trajectory of the lifting platform 243, improving the stability of equipment operation and eliminating radial sway. In this embodiment, the lifting cylinder 241 drives the lifting platform 243 to move vertically via the second transmission link 242, causing the bit assembly 23 mounted on the lifting platform 243 to move vertically synchronously.

[0038] Referring to Figures 1, 2, 3, and 4, in some embodiments, the anti-torsion tube is placed on the positioning base plate 31. The positioning cylinder 322 drives the positioning clamping plate 323 to move up and down relative to the positioning base plate 31, thereby clamping and fixing the anti-torsion tube to the positioning base plate 31. This ensures that the end of the anti-torsion tube is reliably fixed to the positioning base plate 31 during the locking process. Simultaneously, the elastic positioning pin 312 is inserted from bottom to top into the screw hole of the anti-torsion tube, forming a mechanical positioning constraint on the end of the anti-torsion tube. During feeding, the roller rotates within the storage chamber, causing the screws stored in the storage bin 51 to rotate to a high position. Then, the screws are subjected to… Due to gravity, the screws fall onto the distribution guide rail 52, allowing them to align in a specific posture. The distribution guide rail 52 then transports the screws to the feeding conduit 53. Air is then used to propel the screws from the feeding conduit 53 into the inner cavity slide 223, achieving fully automatic feeding. Upon reaching the inner cavity slide 223, the lower opening of the slide 223 is sealed by the clamping block 222 to prevent the screws from slipping directly. Then, the lifting cylinder 241 drives the lifting platform 243 downwards via the second transmission link 242, causing the rotary motor 233 mounted on the lifting platform 243 to move downwards. 233 drives the bit sleeve 231 downward through the first transmission link 232 to fit the bit 23 onto the screw nut, and drives the screw downward to drive the clamp block 222 to rotate outward, opening the lower end opening of the inner cavity slide 223. When the screw abuts against the screw hole of the anti-torsion tube, the torsion motor 233 drives the bit sleeve 231 to rotate through the first transmission link 232, so that the bit sleeve 231 drives the screw to rotate, thereby locking the screw onto the anti-torsion tube. As the screw gradually moves downward, it pushes against the elastic positioning pin 312, causing the elastic positioning pin 312 to gradually retract into the positioning hole 311, thus eliminating the interference of the mechanism movement. Furthermore, the product position is maintained through a dynamic positioning mechanism. After the locking mechanism 2 completes the screw locking of one screw hole of the anti-torsion tube, the locking mechanism 2 resets and then drives the transfer plate 42 to move along the transfer guide rail 41 through the transfer cylinder 43 to align the other screw hole of the anti-torsion tube with the lower end opening of the inner cavity slide 223. Then the locking mechanism 2 repeats the above screw locking action. After the locking is completed, the anti-torsion tube can be rotated 180 degrees and the end of the anti-torsion tube with the screw hole to be locked can be placed on the positioning base plate 31. The above action is repeated to lock the screw of the anti-torsion tube, thereby achieving efficient and high-precision automated screw assembly.
