Description

A type of stabilizing pipe screw machine equipment Technical Field

[0001] This application relates to the field of screw machine technology, and more particularly to a stabilizing tube screw machine device. 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] To overcome bottlenecks, some manufacturers have attempted to introduce fully automated solutions integrating robotic arms and image recognition technology. However, this solution has significant drawbacks: on the one hand, the configuration of high-precision robotic arms and vision systems significantly increases equipment costs, making it difficult for small and medium-sized enterprises to afford; on the other hand, it is difficult to maintain product stability during the tightening process, and mechanical vibration or positioning deviation can easily lead to stripped screws or product damage, resulting in product quality issues. Summary of the Invention

[0004] In order to overcome at least one of the defects described in the prior art, this application provides a stabilizing pipe screw machine that can form mechanical positioning constraints to ensure stable alignment between the product and the support platform during the assembly process.

When the elastic positioning pin extends out of the positioning hole, it is used to engage with the screw hole of the stabilizing tube. When the screw is fastened to the screw hole of the stabilizing tube, the pushing force of the screw will cause the elastic positioning pin to retract into the positioning hole.

[0006] In this stabilizing tube screw machine, an elastic positioning pin extends out of the positioning hole and inserts into the screw hole of the stabilizing tube, forming a mechanical positioning constraint. This ensures the stable alignment of the stabilizing tube and the fixed table during assembly, thereby significantly improving the assembly accuracy of the locking mechanism. Furthermore, when the screw is locked onto the stabilizing tube, its thrust drives the elastic positioning pin to retract synchronously into the positioning hole, eliminating interference in the mechanism's movement and maintaining the stability of the stabilizing tube's position through a dynamic positioning mechanism. This effectively solves the quality defects caused by positioning offset in traditional assembly, achieving efficient and high-precision automated screw assembly.

[0007] According to some embodiments of this application, the locking mechanism includes: a locking frame, which is mounted on the lower base; a clamping member, which is fixed to the locking frame for fixing screws; a bit, which is disposed above the clamping member and can rotate relative to the clamping member; and a lifting member, which is connected to the bit and is used to drive the bit to move up and down, and when the bit moves down, it is fitted onto the screw to drive the screw to move down and / or drive the screw to rotate.

The elastic element is used to drive the pin body out of the positioning hole. When the screw is locked in the screw hole of the stabilizing tube, the pushing of the screw will drive the pin body to compress the elastic element.

They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0027] 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.

[0028] Referring to Figures 1 and 2, this application discloses a screw fastening machine for stabilizing tubes. The screw fastening machine includes a lower base 1, a locking mechanism 2, a fixing platform 3, and a resilient positioning pin 4. In some embodiments, the locking mechanism 2 is mounted on the lower base 1 for fastening screws to the stabilizing tube; the fixing platform 3 is disposed on the lower base 1 and has a positioning hole 34; the resilient positioning pin 4 is disposed in the positioning hole 34 and can extend or retract from the positioning hole 34; when the resilient positioning pin 4 extends out of the positioning hole 34, it is used to engage with the screw hole of the stabilizing tube; when the screw is fastened to the screw hole of the stabilizing tube, the pushing force of the screw will cause the resilient positioning pin 4 to retract into the positioning hole 34. Preferably, the elastic positioning pin 4 extends out of the positioning hole 34 and is inserted into the screw hole of the stabilizing tube to form a mechanical positioning constraint, ensuring the stable alignment of the stabilizing tube and the fixed platform 3 during the assembly process, thereby significantly improving the assembly accuracy of the locking mechanism 2. Furthermore, when the screw is locked onto the stabilizing tube, its thrust drives the elastic positioning pin 4 to retract synchronously into the positioning hole 34, which not only eliminates the interference of the mechanism movement, but also maintains the stability of the stabilizing tube position through the dynamic positioning mechanism. This effectively solves the quality defects caused by positioning offset in traditional assembly, and realizes efficient and high-precision automated screw assembly.

[0029] Optionally, the locking mechanism 2 can be composed of a robotic arm or / or an electric screwdriver, etc.; optionally, the elastic positioning pin 4 can extend or retract via a spring mechanical structure and / or electric components. Further, referring to Figure 1, it also includes an upper cover, which is mounted on the lower base 1 to prevent external interference with screw driving, positioning, and feeding operations. Further, the lower base 1 and / or the upper cover can also be equipped with devices such as a three-color light, warning light, horn, buzzer, and loudspeaker to provide external alerts and inform the user of the current status of the stabilizing tube screw machine; further, the lower base 1 and / or the upper cover can also be equipped with a display screen, touch screen, buttons, etc., to facilitate user operation of the stabilizing tube screw machine.

[0030] Referring to Figure 2, in some embodiments, a positioning frame 31 is mounted on the fixed platform 3. The positioning frame 31 is equipped with a clamping cylinder 32, and the output end of the clamping cylinder 32 is connected to a clamping pressure plate 33. The clamping cylinder 32 is used to drive the clamping pressure plate 33 to move up and down relative to the fixed platform 3, so as to fix the stabilizing tube on the fixed platform 3. Preferably, the clamping cylinder 32 drives the clamping pressure plate 33 to move downward, so as to clamp the stabilizing tube placed on the fixed platform 3. At the same time, the elastic positioning pin 4 extends out of the positioning hole 34 and is inserted into the screw hole of the stabilizing tube to achieve multi-point fixation, avoid stress concentration, and improve the stability of the stabilizing tube when screwed.

[0031] Referring to Figures 3 and 4, in some embodiments, the elastic positioning pin 4 includes a pin body 41, a fixed cylinder 42, and an elastic element 43. The fixed cylinder 42 is fitted to the lower end of the positioning hole 34 and has an elastic cavity that opens upwards. The elastic element 43 is disposed in the elastic cavity. The lower end of the pin body 41 abuts against the upper end of the elastic element 43, and the upper end of the pin body 41 extends into the positioning hole 34. The elastic element 43 is used to drive the pin body 41 out of the positioning hole 34. When the screw is locked in the screw hole of the stabilizing tube, the push of the screw will drive the pin body 41 to compress the elastic element 43. Optionally, the elastic element 43 is a spring. In this embodiment, the pin 41 extends upward through the positioning hole 34 under the elastic force of the elastic element 43, and is used to connect with the screw hole of the stabilizing tube to form a mechanical positioning constraint. When the screw is fastened to the product, its pushing force acts on the elastic element 43 through the pin 41, causing the elastic element 43 to be compressed, thereby driving the pin 41 to retract into the positioning hole 34. This not only eliminates the interference of the mechanism movement, but also maintains the stability of the product 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.

[0032] Referring to Figures 2, 3, and 4, in some embodiments, the locking mechanism 2 includes a locking frame 21, a clamping nozzle 22, a screwdriver bit 23, and a lifting member 24. The locking frame 21 is mounted on the lower base 1; the clamping nozzle 22 is fixed to the locking frame 21 for fixing the screw; the screwdriver bit 23 is disposed above the clamping nozzle 22 and can rotate relative to the clamping nozzle 22; the lifting member 24 is connected to the screwdriver bit 23 for driving the screwdriver bit 23 to move up and down, and when the screwdriver bit 23 moves downward, it is fitted onto the screw to drive the screw to move downward 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 stabilizing tube. Then, the lifting member 24 drives the bit member 23 to move downward, so that the bit member 23 is fitted onto the screw nut and drives the screw to move downward. When the screw abuts against the screw hole of the stabilizing tube, the bit member 23 drives the screw to rotate, so as to lock the screw onto the stabilizing tube, thereby realizing efficient and high-precision automated screw assembly.

[0033] Referring to Figures 2, 3, and 4, in some embodiments, the clamping member 22 includes a clamping body 221 and a clamping opening 222. The clamping body 221 has an inner cavity slide 223 extending through both its upper and lower ends. The bit member 23 extends into the upper opening of the inner cavity slide 223. The clamping opening 222 is located at the lower opening of the inner cavity slide 223. When the bit member 23 moves the screw downward, it will cause the clamping opening 222 to deform outward, thereby opening the lower opening of the inner cavity slide 223. Optionally, the clamping opening 222 may be made of an elastic material, and the clamping opening 222 may open under pressure. When the clamping opening 222 is open, the screw can pass through the clamping opening 222 and leave the clamping member 22. When the clamping opening 222 is closed, it can clamp the screw in the inner cavity slide 223, preventing the stud from being directly exposed. Preferably, the screw is pre-feeded to the inner slide 223, where it is clamped to prevent it from slipping out. Then, the lifting member 24 drives the bit 23 to move downward along the inner slide 223, so that the bit 23 is accurately fitted onto the screw nut under the constraint of the inner slide 223, and drives the screw downward to cause the jaw opening 222 to deform outward, opening the lower end of the inner slide 223. When the screw abuts against the screw hole of the stabilizing tube, the bit 23 drives the screw to rotate, thus locking the screw onto the stabilizing tube, thereby achieving efficient and high-precision automated screw assembly.

[0034] Referring to Figures 2, 3, and 4, in some embodiments, a feeding mechanism is also included. The feeding mechanism includes a storage bin 5, a distributing guide rail 6, and a feeding conduit 7. The storage bin 5 has a storage cavity, in which a roller is disposed. The roller can rotate relative to the storage bin 5 and is used to arrange screws on the distributing guide rail 6. One end of the distributing guide rail 6 extends into the storage cavity, and the other end of the distributing guide rail 6 is connected to the input end of the feeding conduit 7. The output end of the feeding conduit 7 is connected to the inner cavity slide 223 and is used to transport screws to the inner cavity slide 223 (the intermediate section of the pipe from the feeding conduit 7 to the clamping body 221 is not shown in Figure 2). Preferably, the screws are pre-stored in the storage bin 5. 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 6, allowing screws with specific postures to be arranged on the distribution guide rail 6. The distribution guide rail 6 then transports the screws to the input end of the feeding conduit 7. Optionally, a distribution cylinder is provided at the output end of the distribution guide rail 6. The distribution cylinder is used to push the screws from the output end of the distribution guide rail 6 into the feeding conduit 7 one by one. Then, air is blown into the screws in the feeding conduit 7 to transport them into the inner cavity slide 223, thereby achieving fully automatic feeding and further improving the efficiency of automated screw assembly. Optionally, the feeding conduit 7 is blown by an air pump. Optionally, an oil-water separator is provided between the air pump and the feeding conduit 7 to filter moisture from the air.

[0035] 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 a screw. Thus, after the bit sleeve 231 is fitted onto the nut of the screw, the bit sleeve 231 can drive the screw to rotate, thereby securing the screw to the stabilizing 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 stabilizing 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 stabilizing tube, thereby achieving efficient and high-precision automated screw assembly.

[0036] Referring to Figures 3, 4, and 5, in some embodiments, the lifting component 24 includes a lifting platform 241, a lifting cylinder 242, and a second transmission link 243; the lifting platform 241 is connected to the bit component 23; the second transmission link 243 connects the lifting cylinder 242 and the lifting platform 241. Thus, the lifting cylinder 242 converts linear thrust into vertical movement of the first lifting platform 241 via the second transmission link 243, thereby driving the bit component 23 mounted on the lifting platform 241 to move vertically and synchronously.

[0037] Referring to Figures 3, 4, and 5, in some embodiments, a lifting shaft 246 extending along the height direction is further included. A first lifting sleeve 247 is movably connected to the lifting shaft 246, and the first lifting sleeve 247 is connected to the lifting platform 241. Preferably, the lifting shaft 246 is used to constrain the movement trajectory of the lifting platform 241, thereby improving the stability of equipment operation and eliminating radial sway.

[0038] Referring to Figures 2, 3, 4, and 5, in some embodiments, the lifting member 24 further includes: a through hole 244, which is formed in the locking frame 21, and a second transmission link 243 slidably connected to the through hole 244; a pushing element 245, which abuts against the lower end of the locking frame 21, and the second transmission link 243 is fixedly connected to the pushing element 245; and a second lifting sleeve 248, which is fixedly connected to the locking frame 21, and a lifting shaft 246 is slidably connected to the second lifting sleeve 248, and the first lifting sleeve 247 is capable of pushing the second lifting sleeve 248 downward. In this way, when the lifting cylinder 242 drives the lifting platform 241 to move downward through the second transmission link 243, the first lifting platform 241 drives the first lifting sleeve 247 to slide downward along the lifting shaft 246, and simultaneously drives the rotary motor 233 to push the bit sleeve 231 downward through the first transmission link 232, so that the bit piece 23 is fitted onto the nut of the screw and drives the screw to move downward. At the same time, the first lifting sleeve 247 pushes the second lifting sleeve 248 downward, so that the second lifting sleeve 248 drives the clamp piece 22 downward through the locking frame 21, which reduces the distance between the inner cavity slide 223 and the elastic positioning pin 4, preventing the screw from shifting when the bit sleeve 231 pushes the screw downward, and further improving the assembly accuracy of the locking mechanism 2. After the assembly is completed, the lifting cylinder 242 drives the lifting platform 241 to move upward through the second transmission link 243, and the pushing element 245 directly transmits the driving force to the locking frame 21, so as to realize the rapid reset of the locking frame 21.

[0039] Referring to Figures 2, 3, 4, and 5, in some embodiments, the stabilizing tube is placed on the fixed platform 3, and the elastic positioning pin 4 is inserted into the screw hole of the stabilizing tube from bottom to top, forming a mechanical positioning constraint on the stabilizing tube. During feeding, the roller rotates in the storage chamber, causing the screws stored in the storage bin 5 to rotate to a high position. Then, under the influence of gravity, the screws fall onto the distribution guide rail 6, so that the screws conforming to a specific posture can be arranged on the distribution guide rail 6, and then the distribution guide rail 6 will place the screws... The screws are fed into the feeding conduit 7, and then conveyed into the inner cavity slide 223 by air blowing, thus achieving fully automatic feeding. The screws are then clamped in the inner cavity slide 223 by the clamping nozzle 222 to prevent them from slipping out. Then, the lifting cylinder 242 drives the lifting platform 241 downwards via the second transmission link 243, causing the rotary motor 233 mounted on the lifting platform 241 to move downwards. The first transmission link 232 drives the bit sleeve 231 to move downward, so that the bit 23 is fitted onto the screw nut and the screw moves downward, causing the jaw opening 222 to change outward and open the lower end opening of the inner slide 223. When the screw abuts against the screw hole of the stabilizing tube, the rotary 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 stabilizing tube. As the screw gradually moves downward, it pushes against the pin 41 of the elastic positioning pin 4, causing the pin 41 to gradually retract into the positioning hole 34. This eliminates interference in the movement of the mechanism and maintains the stability of the product position through a dynamic positioning mechanism. After the screw is locked, the locking mechanism 2 resets, and the stabilizing tube can be rotated 180 degrees. The end of the stabilizing tube with the screw hole to be locked is placed on the fixed platform 3. The above actions are repeated to lock the screw onto the stabilizing tube, thereby achieving efficient and high-precision automated screw assembly.

It should be noted that those skilled in the art can make several improvements and modifications without departing from the principles of this application, and these improvements and modifications are also considered to be within the scope of protection of this application.
