Description

Technical Field

[0001] The utility model relates to the technical field of nut torque detection, in particular to a nut torque detection device. Background Art

[0002] On an assembly line, when nuts need to be tightened, a nut torque detection device is used to ensure that the torque of each nut meets the predetermined standard or specification. This device can monitor and record the torque of each nut to ensure that the tightening force is appropriate and avoid over-tightening or over-loosening. This is especially important for assembly work that requires precise tightening, such as the manufacturing process of automobiles, aerospace, and mechanical equipment. By using a nut torque detection device, product quality and production efficiency can be improved while ensuring the safety and stability of assembly.

[0003] After searching: Chinese patent announcement number: CN220583650U, it relates to the technical field of nut torque detection, and discloses a nut torque detection device, including: a mounting plate; a sliding plate, the sliding plate is slidably connected to the mounting plate; a first connecting rod, the first connecting rod is slidably connected to the sliding plate; a second connecting rod, the second connecting rod is rotatably connected to the first connecting rod; a detection mechanism, the detection mechanism is connected to the second connecting rod; a marking mechanism, the marking mechanism is connected to the second connecting rod; a first driving mechanism, the first driving mechanism is used to drive the sliding plate to slide on the mounting plate; a second driving mechanism, the second driving mechanism is used to drive the first connecting rod to slide on the sliding plate; a third driving mechanism, the third driving mechanism is used to drive the second connecting rod to rotate. The utility model uses a multi-axis motion method to automatically align the detection mechanism with the nut, and marks unqualified nuts through the marking mechanism, thereby increasing the detection efficiency.

[0004] The above patent embodiment records that "the first driving mechanism drives the sliding plate to slide on the mounting plate, the second driving mechanism is used to drive the first connecting rod to slide on the sliding plate, and the third driving mechanism is used to drive the second connecting rod to rotate, so that the detection mechanism is aligned with the nut. The detection mechanism is provided with a threshold value. When the threshold value is reached, the nut is not screwed, which indicates that the nut is qualified; on the contrary, if the nut is screwed, it indicates that the nut is unqualified. At this time, the marking mechanism marks the nut to serve as a prompt. The utility model uses multi-axis motion to enable the detection mechanism to automatically align the nut and mark the unqualified nuts through the marking mechanism, thereby increasing the detection efficiency." The above embodiment records that the sliding plate is driven by the first driving mechanism to slide on the mounting plate. The nut is rotated by the third driving mechanism so that the detection mechanism is aligned with the nut, and then the detection mechanism drives the nut to rotate. Because the detection mechanism is provided with a threshold value, the nut will not continue to rotate after reaching the threshold value. When the threshold value is reached and the nut continues to rotate, it means that the nut is unqualified and can be marked by a marking mechanism. However, it is not considered that the device can only rotate the screw rod of the same specification, which results in the device being able to detect nuts of the same specification, which will reduce the flexibility of the device. Therefore, in view of the above-mentioned deficiencies, a new type of nut torque detection device is proposed. Utility Model Content

One end of the spring 8 is fixedly connected to the far side of the two sliding plates 9, and the other end of the spring 8 is fixedly connected to the inner wall of the extension shell 6, so that the spring 8 is compressed when the sliding plate 9 moves.

The inside of the limiting hole 15 is slidably connected with a screw rod 16, so that the limiting hole 15 can make the movement of the screw rod 16 more stable, and the outer right side of the screw rod 16 contacts the adjacent side of the two clamping plates 11, so that the clamping plate 11 can clamp and fix the screw rod 16, and the far side of the two studs 13 respectively penetrates the front and rear inner walls of the containing shell 5 and extends outward, and the four corners of the bottom of the marble base 1 are fixedly connected with supporting legs, and the bottom of the supporting legs is fixedly connected with anti-slip pads, so as to improve the stability of the device.

[0027] like Figure 1 and Figure 3 As shown: a hydraulic rod is fixedly connected to the top rear side of the marble base 1, so that the marble base 1 can provide support for the hydraulic rod, a linear guide 27 is fixedly connected to the top left side of the marble base 1, and a sliding block 17 is slidably connected to the outside of the linear guide 27, so that starting the linear guide 27 can make the linear guide 27 drive the sliding block 17 to move, a containing shell 2 18 is fixedly connected to the top of the sliding block 17, and then the sliding block 17 will drive the containing shell 2 18 to move when it moves, a support plate 19 is fixedly connected to the left bottom of the containing shell 2 18, and a motor 20 is fixedly connected to the top of the support plate 19, so that the support plate 19 can provide support for the motor 20, and an output shaft 21 is fixedly connected to the output end of the motor 20, so that starting the motor 20 can make the output end of the motor 20 drive the output shaft 21 to rotate.

[0028] A rotating disk 22 is fixedly connected to the top right side of the output shaft 21, and then when the output shaft 21 rotates, it will drive the rotating disk 22 to rotate. A power groove 23 is opened on the right side of the rotating disk 22, and a plurality of movable plates 24 are slidably connected inside the power groove 23, so that when the rotating disk 22 rotates, it will drive the plurality of power grooves 23 to rotate, and then when the power groove 23 rotates, it will drive the movable plate 24 to move. A clamping block 25 is fixedly connected to the right side of the movable plate 24, and then when the movable plate 24 moves, it will drive the clamping block 25 to move. A plurality of sliding holes 26 are opened on the right side of the accommodating shell 18.

[0029] The outer right sides of the multiple movable plates 24 are all slidably connected to the inside of the sliding hole 26, so that the sliding hole 26 can make the movement of the movable plates 24 more stable. The outer rotation of the rotating disk 22 is connected to the inside of the accommodating shell 218, and the left bottom of the sliding block 17 is fixedly connected to the output end of the hydraulic rod. Therefore, starting the hydraulic rod can make the output end of the hydraulic rod drive the sliding block 17 to slide on the top of the linear guide rail 27.

[0030] Compared with some existing technologies, the above content enables the device to clamp and fix screw rods 16 of different sizes during use, and can make it rotate, so that the screw rod 16 can detect nuts of different sizes, thereby improving the flexibility of use of the device and achieving clamping and fixing of nuts of different sizes, so that the device can detect nuts of different specifications, thereby improving the flexibility of use of the device.

[0031] Working principle: First, it is necessary to assemble screw rods 16 of different specifications, and the screw rod 16 can be inserted into the inside of the limiting hole 15, and then one side of the screw rod 16 enters the inside of the containing shell 5 through the inside of the limiting hole 15. At this time, the stud 13 is rotated to make one side of the two studs 13 press the two sliding plates 9 respectively, and then the outside of the sliding plate 9 will slide inside the sliding hole 12, and then the sliding plate 9 will stretch the spring 8, and the sliding plate 9 will drive the fixed plate 10 to move when it moves, and then the fixed plate 10 will drive the clamping plate 11 to clamp and fix the side of the screw rod 16 entering the inside of the containing shell 5 when it moves, so that the device can clamp and fix screw rods of different specifications, and then start the motor 3 at this time, so that the output end of the motor 3 can drive the output shaft 4 to rotate.

[0032] Then, when the output shaft 14 rotates, it will drive the containing shell 15 to rotate, and then the containing shell 15 will drive the screw rod 16 to rotate, so that the motor 20 is started at this time, so that the output end of the motor 20 drives the output shaft 21 to rotate, and then the output shaft 21 will drive the rotating disk 22 to rotate when it rotates, and then the rotating disk 22 will drive the power slot 23 to rotate when it rotates, so that the power slot 23 will drive the moving plate 24 to slide inside the sliding hole 26 when it moves, and then the moving plate 24 can make the clamping blocks 25 approach each other when it moves, and then the clamping blocks 25 will clamp and fix nuts of different specifications, so after the nuts are clamped and fixed, the hydraulic rod is started to make the hydraulic rod drive the sliding block 17 to slide on the top of the linear guide rail 27.

[0033] Therefore, when the sliding block 17 moves, it will drive the containing shell 2 18 to move, and then when the containing shell 2 18 moves, it will drive the nut to contact the other side of the screw rod 16. Then, because the screw rod 16 is rotating, the nut will rotate outside the screw rod 16. Therefore, because there is a gap between the nut and the right side of the containing shell 2 18, when the nut rotates outside the screw rod 16 to the same distance as the gap, the nut will no longer rotate and become a qualified nut. If the nut continues to rotate, it is an unqualified nut, so that the torque of the nut can be detected.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
