Description

Technical Field

[0001] The invention relates to the technical field of thread fastening, in particular to an adaptively adjustable thread fastening machine unit. Background Art

[0002] A threaded fastening unit is a combination of equipment used to efficiently and accurately tighten threaded connections. It usually includes a power source to provide power for the tightening action; a tightening shaft that transmits and converts power into torque and applies it to the threaded parts; and a control unit that can accurately control parameters such as the torque, tightening speed and angle to ensure that the threaded connection achieves the appropriate preload force. It is widely used in many industrial fields such as automobile manufacturing, mechanical assembly, and large equipment installation to ensure the quality and reliability of threaded connections.

[0003] Existing thread fastening units often have the following disadvantages in actual use:

[0004] First, the existing threaded fastening units mostly use a screw sorting machine to arrange and transport the screws, and then cooperate with a screw installation robot to install the fed screws on the workpiece, thereby achieving the effect of fastening the two workpieces. However, in the actual fastening process, the screw sorting machine often lacks certain effective cleaning components during the transportation process. The outer wall of the screw is often dirty due to the production and transportation links. These dirt may contain metal debris, dust, oil and other impurities. If not handled, when the screw is tightened, on the one hand, it may affect the matching accuracy between the screw and the workpiece thread, causing increased thread wear and reducing the reliability and stability of the connection. Due to the intervention of dirt, the friction coefficient between the threads becomes unstable, causing the screw to be unevenly stressed during the screwing process, and it is easy to have problems such as thread slippage. On the other hand, dirt entering the thread gap may cause corrosion, especially in some humid or chemically corroded environments. Metal debris combines with moisture and oxygen in the air to form an electrolyte solution, which accelerates the corrosion of the screw and the workpiece and shortens the service life of the threaded connection. In serious cases, it may even cause the workpiece to fail to be fastened, causing safety hazards. For example, during the operation of mechanical equipment, loose screws may cause parts to fall off, which will have many adverse effects on product quality and production efficiency, increase rework, maintenance costs and the risk of production stagnation;

[0005] Secondly, in the process of actually fastening two workpieces, the existing threaded fastening machine sometimes needs to use a clamping assembly to fasten a variety of special-shaped workpieces. However, the existing clamping assembly usually consists of two clamping plates that cooperate with the action of a driving member to drive the two clamping plates to move, thereby clamping the special-shaped workpiece. However, this clamping method often has poor adaptability. When fastening two workpieces with completely different shapes and large size differences, the clamping is often unstable or there is a phenomenon of offset during the process of fastening the screws due to the difference in size and shape. For example, for special-shaped workpieces with irregular curved surfaces, concave-convex structures or special angles, it is difficult for traditional clamping plates to fit closely to their surfaces, resulting in uneven force on the workpieces and displacement when tightening the screws. This undoubtedly causes great trouble in actual use, not only reducing the accuracy and efficiency of fastening, but also may cause the screws to be not tightened in place or damage the threads due to the offset of the workpiece, affecting the quality of the entire assembly, and may even damage the workpiece itself, increasing production costs and scrap rates.

[0006] Thirdly, the existing clamping and positioning components mostly play the role of clamping and positioning, and their functionality is relatively lacking. When installing the screw into the threaded hole, the fixing effect of the screw and the threaded hole is often poor relying solely on their own friction. It is very easy to loosen after tightening due to slight external vibration, impact or temperature change. In some high-frequency vibration equipment, such as engines, compressors, etc., the problem of screw loosening is particularly prominent. Due to the lack of auxiliary tightening reinforcement mechanism, the tightening effect is poor, which brings great trouble to the subsequent use of the workpiece. Summary of the invention

The outer wall of the second connecting tube is also provided with a movable port matching the infusion tube.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: in the actual use process, the screws can be neatly arranged and transported to between the guide frame 1 and the guide frame 2 by using a screw material sorting machine, and then the external compressed gas can be input into the gas injection shell. At this time, the gas injection shell can transport the compressed gas to the interior of multiple cleaning parts. The circumferential outer wall of the rotating cylinder included in the multiple cleaning parts is provided with multiple inclined air blowing ports, and these inclined air blowing ports can guide the airflow to be discharged at an angle, and then these airflows will generate a certain force, which can drive the rotating cylinder carrying the brush to rotate. During the rotation of the brush, the surfaces of multiple screws can be cleaned. Cleaning: Since the screw is between the first guide frame and the second guide frame, the brush can clean the surface of the screw, and use the airflow to further clean the impurities on the outer wall of the screw. The cleaned impurities can be transferred to the dust box by the vacuum cleaner for collection, so that it is convenient for unified treatment later. In addition, the brush can also drive the screw to move forward continuously during the rotation process, which can reduce the situation of the screw being blocked by materials. Moreover, the continuous friction cleaning can also drive multiple screws to rotate and move to a certain extent, which can make the circumferential outer wall of the screw be fully cleaned, reducing the dirt on the surface of the screw affecting the later assembly effect.

[0018] And when clamping two workpieces of different shapes, the corresponding screw openings of the two workpieces can be sleeved inside the multiple positioning hollow tubes on the top of the clamping seat, so as to perform preliminary positioning of the two workpieces of different shapes, and then the multiple screw motors can be started to drive the two clamping plates to move. When the two clamping plates are clamping the workpieces of two shapes, the multiple internal telescopic rods of the installation tubes arranged on the outer walls of the two clamping plates will change adaptively according to the shapes of the workpieces, so that they can better fit the two side surfaces of the workpieces to further clamp and limit the two workpieces. When the screws are assembled and installed, the screws will gradually rotate into the corresponding screw holes. In this process, the positioning hollow tube can be continuously moved downward by the action of the second spring, and the positioning can be released only after the screws are completely entered into the screw holes. This composite positioning method can further improve the assembly of screws for two workpieces of different shapes, thereby improving its applicability and stability.

[0019] As the screw continues to rotate into the screw hole, the positioning hollow tube slowly moves down as the screw is screwed in. When it moves down to a specific position, the extrusion plate at the bottom of the positioning hollow tube smoothly enters the interior of the connecting tube. At this time, the friction enhancer pre-stored in the connecting tube is transported to the interior of the positioning hollow tube through the infusion tube under the extrusion force of the extrusion plate, and finally sprayed out evenly through the spray port on the outer circumferential wall of the top of the positioning hollow tube. These friction enhancers can quickly form a layer of medium with a specific roughness between the surface of the screw and the inner wall of the screw hole. In the subsequent process of tightening the screw, these tiny particles or rough structures are tightly squeezed and meshed with each other to form a strong resistance effect, which effectively prevents the screw from loosening or rotating accidentally, thereby better improving the stability of the screw after assembly, significantly reducing the loosening caused by various external factors during later use, greatly improving the reliability and safety of the entire threaded connection structure during long-term operation, and providing a solid foundation for the stable operation of various mechanical equipment and engineering structures.

The plurality of clamping assemblies are located inside the placement grooves. The plurality of clamping assemblies include a clamping plate 330. A positioning assembly is also clamped at the bottom of the inner cavity of the placement grooves. The positioning assembly includes a clamping seat 400.

[0038] Specifically, a sliding door is provided on the front outer wall of the collection box 120, and a vacuum cleaner 130 is provided on the outer wall of the collection box 120 to facilitate vacuuming and transferring of impurities cleaned from the surfaces of multiple screws.

[0039] Furthermore, the top of the connecting plate 230 is rotatably connected to a rotating cylinder 240, an air inlet pipe 231 is provided at the bottom of the connecting plate 230, a brush 242 is provided on the circumferential outer wall of the rotating cylinder 240, and a plurality of inclined air outlets 241 are also provided on the circumferential outer wall of the rotating cylinder 240. The plurality of inclined air outlets 241 can guide the airflow so that it can generate a force to cause the rotating cylinder 240 to rotate, and the generated airflow can also clean the brush 242 to a certain extent.

[0040] Furthermore, an air injection shell 211 is provided at the bottom of the support seat 210, and corresponding through openings 212 are opened at the top of the air injection shell 211 and the support seat 210. The multiple through openings 212 match the air inlet pipe 231 to facilitate the injection of compressed air into the multiple rotating cylinders 240.

[0041] Furthermore, a dust suction port 261 is provided on the outer wall of the second guide frame 260 , and a dust suction box 262 is also provided on the outer wall of the second guide frame 260 . A dust suction pipe 263 is provided at the bottom of the dust suction box 262 , and the end of the dust suction pipe 263 is connected to the dust suction end of the vacuum cleaner 130 .

[0042] It is worth noting that a plurality of clamping plates 330 are internally fixedly sleeved with mounting tubes 340, a spring 341 is disposed on the inner wall of the plurality of mounting tubes 340, and a telescopic rod 342 is connected to the end of the spring 341, so as to facilitate clamping and positioning of workpieces of various shapes.

[0044] In some embodiments: the friction enhancer is in liquid form, wherein liquid friction enhancers such as lubricants containing metal or ceramic particles are more common, and their fluidity enables them to be evenly distributed on the wall of the screw hole by means of spraying or dripping. When the screw is screwed in, these metal or ceramic particles will be between the screw and the hole wall, increasing the friction between the two and effectively preventing the screw from loosening. The friction enhancer is a prior art.

[0046] In some embodiments: the friction enhancer inside the cavity can enter the interior of the fixed cylinder 410 through multiple liquid inlets 420, and then enter the interior of the connecting cylinder 430 through multiple holes 431. When the positioning hollow tube 453 carrying the extrusion plate 455 moves downward, it can generate pressure on the internal friction enhancer, and then enter the interior of the positioning hollow tube 453 through the infusion tube 440, and be evenly sprayed on the inner wall of the screw hole through multiple spray outlets 456, thereby improving the stability and firmness of the screw after installation. When the workpiece is removed after the screw is installed, its spring 2 451 will reset. At this time, the friction enhancer will re-enter the interior of the connecting cylinder 430 through multiple liquid inlets 420 and holes 431, which is convenient for continued use in the future. A liquid level sensor can be set inside the cavity to monitor the liquid level of the friction enhancer so that it can be added by personnel, and the clamping seat 400 can be disassembled and replaced, so as to adapt to the different positions of the screw holes of various workpieces for replacement and use.

A moving port 457 matching the infusion tube 440 is provided on the outer wall of the connecting tube 2 450, so that the infusion tube 440 will not be affected by the moving port 457 when the hollow positioning tube 453 is raised and lowered.

[0049] In some embodiments: the device can be powered by an external conventional power supply, and the device can be controlled by an external PLC console, all of which belong to the prior art.

[0050] Working principle of the present invention: During actual use, the screw sorting machine 200 can be used to neatly arrange the screws and transport them between the guide frame 1 220 and the guide frame 2 260, and then the external compressed gas can be input into the gas injection shell 211. At this time, the gas injection shell 211 can transport the compressed gas to the interior of multiple cleaning parts. The multiple cleaning parts include a rotating cylinder 240 with a plurality of inclined air blowing ports 241 on the circumferential outer wall. These inclined air blowing ports 241 can guide the airflow to be discharged at an angle, and then these airflows will generate a certain force, which can drive the rotating cylinder 242 carrying the brush 242 to rotate. During the rotation of the brush 242, the surfaces of multiple screws can be cleaned. Since the screws are on the guide frame 1 2 20 and the guide frame 260, so the brush 242 can clean the surface of the screw, and use the airflow to further clean the impurities on the outer wall of the screw, and the cleaned impurities can be transferred by the vacuum cleaner 130 to the inside of the dust box 120 for collection, so that it is convenient for later unified treatment, and the brush 242 can also drive the screw to move forward continuously during the rotation process, which can reduce the situation of the screw being blocked, and the continuous friction cleaning can also drive multiple screws to rotate and move to a certain extent, which can make the circumferential outer wall of the screw be fully cleaned, reduce the dirt on the surface of the screw to affect the later assembly effect, and when clamping two workpieces of different shapes, the two workpieces can be clamped correspondingly. The screw mouth is sleeved inside the multiple positioning hollow tubes 453 on the top of the clamping seat 400, and then the two workpieces of two different shapes are preliminarily positioned. After that, the multiple screw motors 320 can be started to drive the two clamping plates 330 to move. When the two clamping plates 330 clamp the workpieces of two shapes, the multiple installation tubes 340 arranged on the outer walls of the two clamping plates 330 have internal telescopic rods 342 that will adaptively change according to the shapes of the workpieces, so that they can better fit the two side surfaces of the workpieces to further clamp and limit the two workpieces. When the screws are assembled and installed, the screws will gradually rotate into the corresponding screw holes. In this process, the positioning hollow tube 453 can utilize the action of the spring 451 to Continuously move downward, and then the positioning can be released only after the screw completely enters the screw hole. This composite positioning method can further improve the assembly of screws between two workpieces of different shapes, and improve its applicability and stability. In the process of the screw continuously rotating into the screw hole, the positioning hollow tube 453 slowly moves downward as the screw is screwed in. When it moves down to a specific position, the extrusion plate 455 at the bottom of the positioning hollow tube 453 smoothly enters the interior of the connecting tube 430. At this time, the friction enhancer pre-stored in the connecting tube 430 is transported to the interior of the positioning hollow tube 453 through the infusion tube 440 under the extrusion force of the extrusion plate 455, and is finally evenly sprayed out through the spray port on the outer wall of the top circumference of the positioning hollow tube 453.These friction enhancers can quickly form a layer of medium with a specific roughness between the screw surface and the inner wall of the screw hole. In the subsequent process of tightening the screw, these tiny particles or rough structures are tightly squeezed and meshed with each other, forming a strong resistance effect, effectively preventing the screw from loosening or rotating accidentally, thereby better improving the stability of the screw after assembly, significantly reducing the loosening caused by various external factors during later use, greatly improving the reliability and safety of the entire threaded connection structure in the long-term operation process, and providing a solid foundation for the stable operation of various mechanical equipment and engineering structures.
