Description

Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing, and in particular to a swingable screw insert device. Background Technology

[0002] Lightweight materials are often used in automotive parts to reduce weight. For example, key components such as engine blocks and gearbox housings are often made of aluminum alloy casting. However, aluminum alloy has low tensile strength and is easily damaged under high loads. Therefore, during production, high-strength steel thread inserts are embedded in the holes of automotive parts. This makes the load distribution on each turn of the thread in the hole more uniform, eliminates pitch and thread profile deviations between the bolt and the threaded hole, and thus enhances the firmness of the automotive parts after connection.

[0003] Currently, screw inserts are screwed in using screw-in devices. However, when screwing in smaller screw inserts, due to the small size of both the screw insert and the hole, when using a PLC to position and screw in the small screw insert, under various factors such as the PLC's control algorithm and environmental interference, the screw insert may deviate from the hole position by micrometers, causing the screw insert to fail to screw in. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a swingable screw insert screwing device. The purpose is to solve the technical problem that, due to the small size of both the screw insert and the hole, when using a PLC to position and screw in a small screw insert, the screw insert will have a micron-level deviation from the hole position under various factors such as the PLC's control algorithm and environmental interference, resulting in the screw insert being unable to be screwed in.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0006] A swingable screw insert device includes a working base. The top of the working base has a fixing device for securing automotive parts. The top of the working base also has a moving device. One side of the moving device has a screw-in portion. The screw-in portion includes a lifting plate located on one side of the moving device. One side of the lifting plate has a mounting base. The top of the mounting base has a screw-in motor. The bottom of the mounting base has a connecting shaft. The screw-in motor drives the connecting shaft to rotate. The bottom of the connecting shaft has a setting seat. The setting seat has a movable cavity inside. The bottom of the setting seat has a movable opening communicating with the movable cavity. A rotating end is hinged inside the movable cavity. One end of the rotating end has a swing connecting rod. One end of the swing connecting rod is located inside the movable cavity, such that the outer edge of the swing connecting rod is separated from the inner edge of the movable cavity by a swing interval. The other end of the swing connecting rod extends out of the movable opening and has a screw-in head.

[0007] When a small insert needs to be screwed into an automotive part, the part is fixed by a fixing device.

When the swing linkage is deflected by force, the rotating shaft can rotate slightly in the rotating hole, allowing the rotating shaft to rotate flexibly and guiding the rotation position of the rotating shaft. The limiting plate is fixed at both ends of the rotating shaft and is larger than the rotating hole, thus preventing the rotating shaft from falling out of the rotating hole during rotation.

[0036] Reference Figures 1-10In some specific embodiments, a swingable screw insert device includes a working base 10. The top of the working base 10 is provided with a fixing device 20 for fixing an automotive part 11. The top of the working base 10 is provided with a moving device 30. One side of the moving device 30 is provided with a screw-in portion 40. The screw-in portion 40 includes a lifting plate 41 located on one side of the moving device 30. One side of the lifting plate 41 is provided with a mounting base 42. The top of the mounting base 42 is provided with a screw-in motor 421, and the bottom of the mounting base 42 is provided with a connecting shaft 440. The screw-in motor 421 drives the connecting shaft 440 to rotate. The bottom of the connecting shaft 440... The part is provided with a mounting base 441, and the mounting base 441 has a movable cavity 442 inside. The bottom of the mounting base 441 has a movable opening 4421 that communicates with the movable cavity 442. A rotating end 443 is hinged inside the movable cavity 442. One end of the rotating end 443 is provided with a swing connecting rod 444. One end of the swing connecting rod 444 is located inside the movable cavity 442, so that the outer edge of the swing connecting rod 444 is separated from the inner edge of the movable cavity 442 by a swing interval 449. The other end of the swing connecting rod 444 passes through the movable opening 4421, and the other end of the swing connecting rod 444 is provided with a screw head 455.

[0037] Through the above technical solution, when a smaller threaded sleeve needs to be screwed into the automotive part 11, the automotive part 11 is fixed by the fixing device 20, and after the screw-in head 455 screws in the threaded sleeve, the threaded sleeve is moved to the hole position of the automotive part 11 by the moving device 30 and screwed in. When there is a micron-level deviation between the threaded sleeve and the hole position, since the rotating end 443 is hinged to the inside of the movable cavity 442, and the outer edge of the swing connecting rod 444 is separated from the inner edge of the movable cavity 442 by a swing interval 449, when the screw-in head 455 inserts the screw into the hole position of the automotive part 11, the hole position of the automotive part 11 will guide the insertion position of the screw-in head 455, so that the swing connecting rod 444 can swing slightly in the movable cavity 442, thereby automatically adapting to the small positional deviation between the threaded sleeve and the hole position of the automotive part, thereby reducing the time for repeated positioning adjustment of the threaded sleeve and improving the success rate of screwing in the threaded sleeve.

[0038] It should be noted that the structure of this application is mainly adapted to situations where the offset between the center of the hole of the automotive part and the initial position of the threaded sleeve is less than or equal to 0.1 mm (100 micrometers). The swing linkage 444 can freely offset within the movable cavity 442, and the screw-in head 455 automatically aligns with the hole of the automotive part 11 by swinging, allowing the threaded sleeve to be screwed in smoothly. If the movable cavity 442 of the swing linkage 444 is used for an offset greater than 0.1 mm (100 micrometers), the swing linkage 444 will be stuck at the edge of the movable cavity 442 and cannot be adjusted further. Furthermore, if the screw-in head 455 swings too much, the thread of the threaded sleeve and the hole of the automotive part 11 will be completely misaligned. Forcing it in will damage the thread or cause the screw-in motor 421 to overload and stop.

[0039] Reference Figures 7-10 In some specific embodiments, a rotating groove 445 is provided inside the rotating end 443, and rotating holes 446 are provided on both sides of the mounting base 441. A rotating shaft 447 is inserted inside the rotating groove 445. The two ends of the rotating shaft 447 are respectively rotatably engaged with the rotating holes 446 on both sides of the mounting base 441. The two ends of the rotating shaft 447 respectively pass through the adjacent rotating holes 446. A limiting plate 448 is provided at the end of the rotating shaft 447. The size of the limiting plate 448 is larger than that of the rotating hole 446. The limiting plate 448 is located outside the mounting base 441.

[0040] With the above technical solution, the rotating shaft 447 passes through the rotating holes 446 on both sides of the mounting base 441 to form a rotating fulcrum. When the swing link 444 is deflected by force, the rotating shaft 447 can rotate slightly in the rotating hole 446, so that the rotating shaft 447 can rotate flexibly and guide the rotation position of the rotating shaft 447. The limiting plate 448 is fixed at both ends of the rotating shaft 447 and its size is larger than the rotating hole 446, thereby preventing the rotating shaft 447 from falling out of the rotating hole 446 during rotation.

[0041] Reference Figure 9 In some specific embodiments, the other end of the swing link 444 is provided with a connecting rod 450, one end of the connecting rod 450 is provided with a mounting end 451, one end of the mounting end 451 is provided with a mounting groove 452, the internal thread of the mounting groove 452 is fitted with a fixing rod 453, and a screw-in head 455 is provided at one end of the fixing rod 453.

[0042] Through the above technical solution, the screw-in head 455 is connected to the mounting end 451 via the fixing rod 453 to form a detachable structure; when it is necessary to replace the screw-in head 455 of different specifications (such as to deal with different sizes of threaded sleeves), it is only necessary to rotate and remove the fixing rod 453 to replace it, which simplifies the replacement method of the screw-in head 455.

[0043] Reference Figures 8-9 In some specific embodiments, a rotating seat 454 is provided at one end of the fixed rod 453. The rotating seat 454 is hexagonal in shape, and a screw-in head 455 is provided at one end of the rotating seat 454.

[0044] Through the above technical solution, the rotating seat 454 is designed as a hexagon (i.e., a hexagonal prism) to match the interface of standard tools (such as hex wrenches) and form a stable mechanical transmission structure. When it is necessary to tighten or loosen the fixing rod 453, simply place the hex wrench on the rotating seat 454 and rotate the fixing rod 453 by rotating the tool, thereby improving the stability of the screw head 455 after installation.

[0045] Reference Figures 4-10In some specific embodiments, the bottom of the mounting base 42 is provided with a first connecting base 430, and the motor 421 drives the first connecting base 430 to rotate. One end of the first connecting base 430 is provided with a first universal coupling 431, and one end of the first universal coupling 431 is provided with a second universal coupling 432. The top of the connecting shaft 440 is connected to one end of the second universal coupling 432.

[0046] Through the above technical solution, the screw-in motor 421 drives the first connecting seat 430 to rotate, and the power is transmitted to the second universal coupling 432 through the first universal coupling 431. Finally, the rotational motion is transmitted to the screw-in head 455 by the connecting shaft 440. When the screw-in head 455 swings due to deviation, the first universal coupling 431 and the second universal coupling 432 compensate for the angle change caused by the offset of the swing connecting rod 444 through angle compensation (existing technology, so it will not be described in detail). This ensures that the screw-in head 455 rotates at a uniform speed and prevents the screw sleeve from being screwed in unevenly or the threads from being damaged due to speed fluctuations.

[0047] Reference Figures 5-10 In some specific embodiments, a support frame 460 is provided on one side of the lifting plate 41, a connecting arm 461 is provided on one side of the support frame 460, a connecting cylinder 462 is provided on one side of the connecting arm 461, a connecting shaft 440 is slidably engaged with the connecting cylinder 462, a buffer spring 463 is sleeved on the outside of the connecting shaft 440, one end of the buffer spring 463 abuts against the connecting cylinder 462, and the other end of the buffer spring 463 abuts against the mounting seat 441.

[0048] Through the above technical solution, when the screw-in head 455 is subjected to external force (such as the reaction force when the screw sleeve is screwed in), the connecting shaft 440 can compress the buffer spring 463 to form an elastic buffer, thereby avoiding damage to the hole of the automotive part 11 by the impact force of the screw-in head 455, and also reducing the impact force of the screw-in head 455.

[0049] Reference Figures 1-5 In some specific embodiments, the moving device 30 includes a moving bracket 31 disposed on the top of the work base 10. A moving frame 32 is provided horizontally on the top of the moving bracket 31. A moving cavity 321 is opened on one side of the moving frame 32. A moving screw 322 is rotatably connected inside the moving cavity 321. A moving motor 323 is provided at one end of the moving frame 32. The moving motor 323 drives the moving screw 322 to rotate. A moving nut 33 is sleeved on the outside of the moving screw 322. A moving connecting plate 331 is provided on one side of the moving nut 33. A lifting plate 41 is disposed on one side of the moving connecting plate 331.

[0050] Through the above technical solution, the movable motor 323 drives the movable lead screw 322 to rotate through the output shaft. The movable lead screw 322 is threadedly engaged with the movable nut 33, which converts the rotational motion of the movable lead screw 322 into the linear motion of the movable nut 33. This causes the movable nut 33 to drive the movable connecting plate 331 to move laterally, so as to move the screw head 455 above the automotive part 11.

[0051] Reference Figures 1-5 In some specific embodiments, a lifting frame 34 is vertically provided on one side of the movable connecting plate 331, and a lifting cavity 341 is provided on one side of the lifting frame 34. A lifting screw 342 is rotatably connected inside the lifting cavity 341. A lifting motor 343 is provided at one end of the lifting frame 34, and the lifting motor 343 drives the lifting screw 342 to rotate. A lifting nut 344 is sleeved on the outside of the lifting screw 342. A lifting connecting plate 345 is provided on one side of the lifting nut 344, and a lifting plate 41 is provided on one side of the lifting connecting plate 345.

[0052] Through the above technical solution, the lifting motor 343 drives the lifting screw 342 to rotate through the output shaft. The lifting screw 342 and the lifting nut 344 are threaded together, converting the rotational motion of the lifting screw 342 into the linear motion of the lifting nut 344. This causes the lifting nut 344 to drive the movable connecting plate 331 to move vertically, so as to lower the screw sleeve of the screw head 455 into the hole of the automotive part 11. When the screw head 455 is rotated by the screw motor 421, the movable connecting plate 331 drives the screw sleeve of the screw head 455 to be screwed into the hole of the automotive part 11.

[0053] Reference Figures 1-5 In some specific embodiments, the fixing device 20 includes a fixing plate 220, which is movably disposed on the top of the work seat 10. The top of the fixing plate 220 is provided with a plurality of positioning pins 221. The exterior of the automotive part 11 is provided with a plurality of positioning holes 111. The plurality of positioning pins 221 are respectively inserted into the plurality of positioning holes 111. The top of the positioning pins 221 is formed with a conical guide plug 222.

[0054] Through the above technical solution, the design of the conical guide plug 222 utilizes the inclined plane guiding principle. When the positioning pin 221 initially contacts the positioning hole 111, the conical surface slides to automatically correct the slight deviation, and finally guides the positioning pin 221 to fall precisely into the positioning hole 111. The automotive part 11 is limited by multiple positioning pins 221, thereby preventing the automotive part 11 from shifting its position when screwed into the screw sleeve.

[0055] Reference Figures 1-5In some specific embodiments, the fixing device 20 includes an adjusting frame 21 horizontally disposed on the top of the work base 10. An adjusting cavity 211 is opened on the top of the adjusting frame 21. An adjusting screw 212 is rotatably connected inside the adjusting cavity 211. An adjusting motor 213 is provided at one end of the adjusting frame 21. The adjusting motor 213 drives the adjusting screw 212 to rotate. An adjusting nut 230 is sleeved on the outside of the adjusting screw 212. An adjusting connecting plate 231 is provided on one side of the adjusting nut 230. A fixing plate 220 is disposed on the top of the adjusting connecting plate 231.

[0056] Through the above technical solution, the adjusting motor 213 drives the adjusting screw 212 to rotate through the output shaft. The adjusting screw 212 and the adjusting nut 230 are threaded together, converting the rotational motion of the adjusting screw 212 into the linear motion of the adjusting nut 230. This causes the adjusting nut 230 to move the adjusting connecting plate 231, so as to drive the fixing plate 220 to adjust the processing position of the automotive part 11.
