[0027] Embodiment 1

[0028] like Figure 1-Figure 4As shown, the fastening detection device for steel structure engineering proposed by the utility model includes a base 1, a linear motor 2, a transmission rod 3, a support bracket 4, a mounting bracket 5, a sliding member 6, a support plate 7, a sensor bracket 8, a sensor 9, a bidirectional screw 10, a clamping member 11, a limit member 12, a limit groove 13, a driving slide rail 14, a lifting member 15, a motor bracket 16, a rotating motor 17, a rotating shaft 18, a rotating bracket 19, a torque sensor 20, a connector 21 and a control module 22;

[0029] A linear motor 2 is provided on the top of the base 1; a clamping structure for driving and clamping a threaded fastener is provided on the linear motor 2; a support plate 7 is provided on the top of the base 1; a sensor bracket 8 is provided on the side of the support plate 7; a sensor 9 is provided on the end of the sensor bracket 8 away from the support plate 7; the sensor 9 faces the direction of the clamping structure; a lifting structure for vertical lifting and sliding is provided on the top of the support plate 7;

[0030] The clamping structure includes a transmission rod 3; a mounting bracket 5 is provided on the end of the transmission rod 3 away from the linear motor 2; a sliding member 6 is provided on the bottom of the mounting bracket 5; the bottom of the sliding member 6 is slidably connected to the base 1; the top of the sliding member 6 is connected to the bottom of the mounting bracket 5; a supporting bracket 4 is provided on the base 1; the top side of the supporting bracket 4 is connected to the linear motor 2; the bottom of the linear motor 2 is slidably connected to the sliding member 6; a sliding groove is provided on the side of the mounting bracket 5; a plurality of groups of clamping members 11 are provided on the side of the mounting bracket 5; a threaded bidirectional screw rod 10 is provided on the side of the plurality of groups of clamping members 11; the side of the bidirectional screw rod 10 is rotatably connected to the mounting bracket 5; a limiting member 12 is provided on the side of the clamping member 11, and a limiting groove 13 is provided on the side of the limiting member 12;

[0031] The lifting structure includes a driving slide rail 14; a lifting member 15 with a sliding connection is provided on the end of the driving slide rail 14 away from the support plate 7; a motor bracket 16 is provided on the side of the lifting member 15; a rotating motor 17 is provided on the end of the motor bracket 16 away from the lifting member 15; a rotating shaft 18 is provided on the bottom output end of the rotating motor 17; a torque sensor 20 is provided on the end of the rotating shaft 18 away from the rotating motor 17; a rotating bracket 19 is provided on the side of the lifting member 15; the side of the rotating bracket 19 is rotatably connected to the torque sensor 20; a connecting head 21 is provided on the bottom of the torque sensor 20; the connecting head 21 faces the clamping structure, and a control module 22 is provided on the side of the support plate 7, and the control module 22 is control-connected to the driving slide rail 14.

[0032] In this embodiment, the device can effectively improve the accuracy of detecting the rotational tightening of the fastener. The rotating connecting head 21 drives the fastener to rotate relatively, so that the maximum resistance when the current fastener is loosened can be detected, thereby judging the loosening performance of the current fastener.

[0033] When the device is in working state, the fastener nut is placed between the limiting grooves 13. At this time, the synchronous rotation of multiple sets of bidirectional screw rods 10 can make the clamping parts 11 slide toward each other, so that the limiting parts 12 squeeze each other and clamp the fastener nut structure through the structure of the limiting grooves 13. The clamping method can prevent the nut from rotating during the detection process.

[0034] At this time, the thread of the bolt structure is rotated on the nut until the bolt cannot be rotated. At this time, the sleeve corresponding to the bolt can be installed through the structure of the connecting head 21, thereby ensuring the stable transmission connection between the connecting head 21 and the bolt. The torque sensor 20 is driven to rotate by the rotating motor 17, and the connecting head 21 is driven to rotate by the torque sensor 20. The bolt is driven to rotate by the connecting head 21. At this time, when the connecting head 21 is connected to the bolt, the resistance of the bolt will be transmitted to the torque sensor 20. As the rotation force of the rotating motor 17 increases, the bolt will be gradually rotated in the opposite direction until it loosens. After the bolt rotates, the rotating motor 17 can be driven by the driving slide rail 14 and the lifting member 15. The connection joint 21 rises with the rising process of the bolt, thereby ensuring that the bolt will not be squeezed with the bottom of the connection joint 21 during the loosening process. The connection joint 21 rises with the rising process of the bolt, providing space for the bolt to rise and rotate while ensuring the transmission of rotational power; the torque sensor 20 can record the maximum rotational torque. At this time, the fastener combination with a maximum torque reaching a certain value is a qualified product, and the fastener combination that can be rotated and loosened too easily is an unqualified product. The device can more accurately detect the actual use stability of the current fastener through the rotation detection effect of the fastener combination. Compared with the traditional device for detecting the side rigidity of the fastener, the thread resistance detection of the device is more practical.

[0035] After the bolt is completely separated from the nut, the linear motor 2 drives the mounting bracket 5 to slide. The sliding member 6 can provide support for the mounting bracket 5 during the sliding process of the mounting bracket 5. The linear motor 2 drives the mounting bracket 5 to slide under the sensor bracket 8. The sensor 9 facing the nut can detect whether the internal thread structure of the nut is deformed after the tightening thread is rotated. The nut without deformation is a qualified product. The accuracy of the sliding position can be guaranteed by the structure of the linear motor 2, which ensures the accuracy of the position of the sensor 9 facing the nut.

[0036] The control module 22 controls the driving slide rail 14 to drive the lifting member 15 to rise and slide, so that when the connecting joint 21 of the device is docked with the bolt, the downward sliding from top to bottom can facilitate the combination and connection of the connecting joint 21 with bolts of various lengths. At the same time, in the process of loosening the bolt, the lifting member 15 can rise according to the rise of the bolt thread, thereby avoiding excessive extrusion between the connecting joint 21 and the top of the bolt. The structure of the control module 22 can detect the working state of the rotating motor 17. When the loosening resistance is initially carried out, the rotating motor 17 is in a non-rotating state. At this time, the height of the lifting member 15 is fixed. When the rotating motor 17 rotates, it means that the bolt has been loosened. Therefore, the lifting member 15 slides upward to ensure stable thread rotation of the bolt.

[0037] Embodiment 2

[0038] like Figure 1-Figure 4 As shown, the fastening detection device for steel structure engineering proposed by the utility model, compared with the first embodiment, in this embodiment, a connecting groove is provided on the bottom of the connecting head 21, a detachable sleeve is provided on the bottom of the connecting groove, an external hexagonal protrusion is provided on the top of the bolt, and an internal hexagonal groove is provided on the bottom of the sleeve, and the sleeve is transmission-connected to the top of the bolt through the internal hexagonal groove.

[0039] The combination of the connecting groove and the docking head ensures that the sleeve can accurately dock with the fastener when the driving slide rail 14 drives the lifting member 15 to press down, thereby avoiding problems such as reduced detection accuracy due to loosening between the connecting head 21 and the bolt.
