[0001] The present invention relates to the technical field of non-standard nut production, and specifically to a detection device for non-standard nut production. Background Art

[0002] A non-standard nut refers to a customized nut that does not conform to standard specifications and needs to be used in conjunction with a bolt or screw rod to achieve a fastening function through internal threads. Its specifications, materials, surface treatments, etc. can all be customized according to requirements and are suitable for mechanical connection requirements in special scenarios. After the production of non-standard nuts, it is necessary to use a detection device to detect the anti-loosening performance of the non-standard nuts.

[0003] When the existing anti-loosening performance detection device for non-standard nuts is in use, since the shapes and sizes of non-standard nuts are not standard specifications, when tightening non-standard nuts, it is necessary to tighten non-standard nuts manually. The existing automatic tightening structures cannot be applied to non-standard nuts with different shapes and sizes, resulting in low detection efficiency for non-standard nuts and inconvenient use. Therefore, we propose a detection device for non-standard nut production to solve the problems raised. Summary of the Invention

The screw rod is installed on the vibration detection table through a mounting seat. A first hydraulic rod is installed at the top of the base close to the vibration detection table. An elevating frame is installed at the top of the first hydraulic rod. A turntable is arranged below the elevating frame far from the first hydraulic rod. The top of the turntable is rotationally connected to the elevating frame through a rotating shaft. Clamping frames are symmetrically arranged at the bottom of the turntable. The clamping frames are controlled to approach or move away from each other through a clamping mechanism. A plurality of clamping plate grooves are equidistantly opened on the inner side of the clamping frames close to the lower part. A clamping plate is arranged inside the clamping plate grooves. One end of the clamping plate located inside the clamping plate groove is fixedly connected with a first piston. A communication groove is communicated with the inner side of the clamping frame close to the clamping plate groove. A piston cylinder is installed on the outer side of the clamping frame corresponding to the communication groove. A piston groove is communicated with one side of the piston cylinder corresponding to the communication groove. A guide rod groove is opened at one end of the piston cylinder far from the clamping frame. A guide rod penetrates through the guide rod groove. One end of the guide rod located inside the piston groove is fixedly connected with a second piston. A spring is sleeved on the guide rod between the second piston and the inner wall of the piston groove. A fastening bolt is threadedly connected above the piston cylinder corresponding to the guide rod groove.

[0006] Preferably, guide columns are symmetrically and fixedly connected to the top of both sides of the base near the first hydraulic rod. Guide grooves are formed at the tops of the guide columns, and guide rods are fixedly connected to the bottom of the lifting frame corresponding to the guide grooves.

[0007] Preferably, the guide rod is a cylinder, and the outer diameter of the guide rod is consistent with the inner diameter of the guide groove.

[0008] Preferably, the clamping mechanism includes a mounting frame. The mounting frame is installed at the top of the lifting frame corresponding to the rotating shaft. A second hydraulic rod is installed on the mounting frame. Telescopic grooves penetrate through the middle parts of the turntable and the rotating shaft. The telescopic end of the second hydraulic rod corresponding to the telescopic groove is rotatably connected to a telescopic rod. The turntable is driven by a driving mechanism to rotate. Clamping frames are symmetrically and slidably arranged at the bottoms of both sides of the turntable. A transmission groove penetrates through the upper side of the clamping frame near the top. A transmission rod is fixedly connected to one side of the telescopic rod corresponding to the transmission groove.

[0009] Preferably, the transmission grooves on both sides below the turntable are distributed in a shape of an inverted V, and the inner diameter of the transmission groove is consistent with the outer diameter of the transmission rod.

[0010] Preferably, the driving mechanism includes a motor. The motor is installed at the top of the lifting frame near the first hydraulic rod. A first gear is installed on the outer side of the rotating shaft near the lower part of the lifting frame. A second gear is installed at the shaft end of the motor corresponding to the first gear. The first gear and the second gear are connected by a transmission toothed belt.

[0011] Preferably, the tooth pitches of the first gear, the second gear and the transmission toothed belt are equal, and both the first gear and the second gear are meshed with the transmission toothed belt.

[0012] Preferably, a sliding groove is formed at the bottom of the turntable corresponding to the clamping frame, and a sliding block is fixedly connected to the top of the clamping frame corresponding to the sliding groove.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: In the present invention, the lifting of the clamping frame is controlled by the first hydraulic rod. When it is necessary to detect the anti-loosening performance of non-standard nuts, the clamping mechanism is used to control the clamping frames to approach each other to clamp the non-standard nuts. At the same time, the guide rod is in a movable state. When the clamping frames approach each other and abut against the outer side of the non-standard nut, the movable clamping plate can adaptively adjust according to the external shape and size of the non-standard nut. When the clamping plate drives the first piston to move, the hydraulic oil in the communication groove pushes the second piston to move, and the second piston drives the guide rod to move. After completely clamping the non-standard nut, the fastening bolt is tightened to fix the guide rod, and thus the position of the clamping plate can be positioned. The adaptively adjustable clamping plate can be applicable to non-standard nuts of different shapes and sizes. In cooperation with the driving mechanism to drive the turntable to rotate, the non-standard nut can be driven to be tightened. When detecting the anti-loosening performance of non-standard nuts of the same batch, in cooperation with the adaptively adjustable clamping structure, through a single adjustment, it can automatically tighten the non-standard nuts of the same batch instead of manual operation, effectively reducing the labor intensity of the staff and improving the detection efficiency.

[0015] In the present invention, when the second hydraulic rod controls the telescopic rod to expand and contract, it drives the telescopic rod to move up and down. When the telescopic rod moves downward, through the inclined transmission rod and the transmission groove, the clamping frames can be driven to approach each other. When the telescopic rod moves upward, the clamping frames can be driven to move away from each other. Through this clamping mechanism, the clamping frames can be controlled to approach or move away from each other. And when the motor works, the second gear, the transmission belt and the first gear drive the rotating shaft to rotate, so that the rotating shaft drives the clamping frame to rotate through the turntable. Through the cooperation of this driving mechanism and the clamping mechanism, the clamping frame can be controlled to clamp and rotate the non-standard nut, so as to automatically tighten the non-standard nut.

DETAILED DESCRIPTION

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example

[0019] See also Figures 1 to 7 The present invention provides a technical solution: a detection device for non-standard nut production, comprising a base 1, the four corners of the bottom of the base 1 are symmetrically fixed with legs 2, and a vibration detection table 3 is installed on the top of one side of the base 1, wherein, A screw rod 4 is provided at the middle of the top of the vibration detection platform 3, and the screw rod 4 is installed on the vibration detection platform 3 through a mounting seat 5. A first hydraulic rod 6 is installed on the top of the base 1 near the top of the vibration detection platform 3, and a lifting frame 7 is installed on the top of the first hydraulic rod 6. A turntable 11 is provided below the lifting frame 7 away from the first hydraulic rod 6. The top of the turntable 11 is rotatably connected to the lifting frame 7 through a rotating shaft 12. Clamping frames 21 are symmetrically provided at the bottom of the turntable 11. The clamping frames 21 are controlled to move closer or farther away from each other by a clamping mechanism. Clamping plate grooves 26 are equidistantly provided on the inner side of the clamping frame 21 near the bottom, and a clamping plate 27 is provided on the inner side of the clamping plate groove 26. The clamping plate 27 is located in the clamping plate groove 26 and is fixedly connected to a first piston 28 at one end. The inner side of the clamping frame 21 near the clamping plate groove 26 is connected to a connecting groove 29. A piston cylinder 30 is installed on the outer side of the clamping frame 21 corresponding to the connecting groove 29. The side of the piston cylinder 30 corresponding to the connecting groove 29 is connected to the piston groove 31. A guide rod groove 32 is opened at the end of the piston cylinder 30 away from the clamping frame 21. A guide rod 33 runs through the guide rod groove 32. One end of the guide rod 33 located in the piston groove 31 is fixedly connected to a second piston 34. A spring 35 is sleeved on the guide rod 33 between the second piston 34 and the inner wall of the piston groove 31. A fastening bolt 36 is threadedly connected to the upper side of the piston cylinder 30 corresponding to the guide rod groove 32. The clamping frame 21 is controlled to lift by the first hydraulic rod 6. When it is necessary to detect the loosening prevention performance of non-standard nuts, the screw rod 4 to be detected is installed on the vibration detection table 3 by means of bolt fixation. The clamping mechanism is used to control the clamping frames 21 to approach each other to clamp the non-standard nuts. At the same time, the guide rod 33 is in an active state. When the clamping frames 21 approach each other and abut against the outer side of the non-standard nut, through the movable clamping plate 27, it can be adaptively adjusted according to the external shape and size of the non-standard nut. When the clamping plate 27 drives the first piston 28 to move, the hydraulic oil in the communication groove 29 is used to push the second piston 34 to move, and the second piston 34 drives the guide rod 33 to move. After the non-standard nut is completely clamped, the fastening bolt 36 is tightened to fix the guide rod 33, and then the position of the clamping plate 27 can be positioned. Through the clamping plate 27 with adaptive adjustment, it can be applied to non-standard nuts of different shapes and sizes. Cooperating with the driving mechanism to drive the turntable 11 to rotate, the non-standard nut can be driven to be tightened. When detecting the loosening prevention performance of non-standard nuts of the same batch, cooperating with the clamping structure with adaptive adjustment, through a single adjustment, it can replace manual labor to automatically tighten the non-standard nuts of the same batch, effectively reducing the labor intensity of the staff and improving the detection efficiency.

[0020] Please refer to Figures 1 to 7 As shown in the figure, symmetrically fixed to the top of both sides of the base 1 near the first hydraulic rod 6 are guide columns 8. A guide groove 9 is opened at the top of the guide column 8. Corresponding to the bottom of the guide groove 9, the lifting frame 7 is fixedly connected with a guide rod 10. The guide rod 10 is a cylinder, and the outer diameter of the guide rod 10 matches the inner diameter of the guide groove 9. When the first hydraulic rod 6 drives the clamping frame 21 to lift through the lifting frame 7, through the guiding structure formed by the guide groove 9 and the guide rod 10, the lifting of the lifting frame 7 can be guided to prevent the lifting of the lifting frame 7 from deviating.

[0021] Please refer to Figures 1 to 7, the clamping mechanism includes a mounting frame 13. The lifting frame 7 is provided with a mounting frame 13 at the top corresponding to the rotating shaft 12. A second hydraulic rod 14 is mounted on the mounting frame 13. The turntable 11 and the middle of the rotating shaft 12 are both penetrated by a telescopic groove 15. The telescopic end of the second hydraulic rod 14 corresponding to the telescopic groove 15 is rotatably connected to a telescopic rod 16. The turntable 11 is driven by a driving mechanism to rotate. Clamping frames 21 are symmetrically and slidably arranged at the bottom of both sides of the turntable 11. A transmission groove 24 penetrates through the upper side of the clamping frame 21 close to it. One side of the telescopic rod 16 corresponding to the transmission groove 24 is fixedly connected to a transmission rod 25. The transmission grooves 24 on both sides below the turntable 11 are distributed in a shape of an inverted V, and the inner diameter of the transmission groove 24 matches the outer diameter of the transmission rod 25. When the second hydraulic rod 14 controls the telescopic rod 16 to expand and contract, it drives the telescopic rod 16 to move up and down. When the telescopic rod 16 moves downward, through the inclined transmission rod 25 and the transmission groove 24, the clamping frames 21 can be driven to approach each other. When the telescopic rod 16 moves upward, the clamping frames 21 can be driven to move away from each other. Through this clamping mechanism, the clamping frames 21 can be controlled to approach or move away from each other.

[0022] Please refer to Figures 1 to 7 , the driving mechanism includes a motor 17. The lifting frame 7 is provided with a motor 17 at the top close to the first hydraulic rod 6. A first gear 18 is mounted on the outer side of the rotating shaft 12 close to the lower part of the lifting frame 7. A second gear 19 is mounted on the shaft end of the motor 17 corresponding to the first gear 18. The first gear 18 and the second gear 19 are connected by a transmission belt 20. The pitch of the teeth of the first gear 18, the second gear 19 and the transmission belt 20 is equal, and both the first gear 18 and the second gear 19 are meshed with the transmission belt 20. When the motor 17 works, the rotating shaft 12 is driven to rotate through the second gear 19, the transmission belt 20 and the first gear 18, so that the rotating shaft 12 drives the clamping frame 21 to rotate through the turntable 11. Through the cooperation of this driving mechanism and the clamping mechanism, the clamping frame 21 can be controlled to clamp and rotate the non-standard nut, so as to automatically tighten the non-standard nut.

[0023] Please refer to Figures 1 to 7 , a chute 22 is opened at the bottom of the turntable 11 corresponding to the clamping frame 21. A slider 23 is fixedly connected to the top of the clamping frame 21 corresponding to the chute 22. The guide rod 33 is rectangular columnar, and the external dimensions of the guide rod 33 match the internal dimensions of the guide rod groove 32. When the clamping frames 21 approach or move away from each other, through the guiding structure formed by the chute 22 and the slider 23, the movement of the clamping frames 21 can be guided to avoid the deviation of the movement of the clamping frames 21.

[0024] Working principle: This non-standard nut production inspection device controls the lifting of the clamping frame 21 through the first hydraulic rod 6. When it is necessary to inspect the anti-loosening performance of non-standard nuts, the inspected screw rod 4 is installed on the vibration inspection table 3 by means of bolt fixation. The clamping mechanism controls the clamping frames 21 to approach each other to clamp the non-standard nuts. At the same time, the guide rod 33 is in a movable state. When the clamping frames 21 approach each other and abut against the outer side of the non-standard nut, through the movable clamping plate 27, it can be adaptively adjusted according to the external shape and size of the non-standard nut. When the clamping plate 27 drives the first piston 28 to move, the hydraulic oil in the communication groove 29 pushes the second piston 34 to move, and the second piston 34 drives the guide rod 33 to move. After completely clamping the non-standard nut, tighten the fastening bolt 36 to fix the guide rod 33, and then the position of the clamping plate 27 can be positioned. Through the adaptively adjusted clamping plate 27, it can be applied to non-standard nuts of different shapes and sizes. Cooperating with the driving mechanism to drive the turntable 11 to rotate, the non-standard nut can be driven to be tightened. When inspecting the anti-loosening performance of non-standard nuts in the same batch, cooperating with the adaptively adjusted clamping structure, through a single adjustment, it can replace manual labor to automatically tighten the non-standard nuts in the same batch, effectively reducing the labor intensity of the staff and improving the inspection efficiency. After loosening the fastening bolt 36, the spring 35 can push the second piston 34 to reset, and then the second piston 34 can drive the clamping plate 27 to reset; When the first hydraulic rod 6 drives the clamping frame 21 to lift through the lifting frame 7, the guiding structure composed of the guiding groove 9 and the guiding rod 10 can guide the lifting of the lifting frame 7 to prevent the lifting of the lifting frame 7 from shifting. And when the second hydraulic rod 14 controls the telescopic rod 16 to expand and contract, it drives the telescopic rod 16 to move up and down. When the telescopic rod 16 moves downward, through the inclined transmission rod 25 and the transmission groove 24, the clamping frames 21 can be driven to approach each other. When the telescopic rod 16 moves upward, the clamping frames 21 can be driven to move away from each other. Through this clamping mechanism, the clamping frames 21 can be controlled to approach or move away from each other. And when the motor 17 works, the second gear 19, the transmission belt 20 and the first gear 18 drive the rotating shaft 12 to rotate, so that the rotating shaft 12 drives the clamping frame 21 to rotate through the turntable 11. Through the cooperation of this driving mechanism and the clamping mechanism, the clamping frame 21 can be controlled to clamp and rotate the non-standard nut, so as to automatically tighten the non-standard nut.
