DETAILED DESCRIPTION

[0017] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.

[0018] Example: See Figure 1-2 In order to solve the problems of large errors and difficulty in ensuring detection efficiency in the current manual detection method, a threaded workpiece inspection device is set up, including a mounting frame 1 and a mounting plate 2, characterized in that the mounting plate 2 is fixedly mounted on the rear side of the mounting frame 1, a mobile detection structure is provided on the upper end of the mounting plate 2, and a rotating mounting structure is embedded in the mounting frame 1;

[0019] The mobile detection structure includes: a linear module 3, a connecting frame 4, a fixed frame 5, a torque sensor 6, a connecting seat 7 and a threaded sleeve 8;

[0020] The linear module 3 is fixedly installed on the rear side of the mounting plate 2, the connecting frame 4 is fixedly installed on the driving end of the linear module 3, the fixed frame 5 is movably mounted on the upper end of the mounting plate 2, and one end is connected to the connecting frame 4, the torque sensor 6 is fixedly installed on the upper end of the fixed frame 5, and the bottom end is movably embedded in the fixed frame 5, the connecting seat 7 is fixedly installed on the lower end of the torque sensor 6, and the threaded sleeve 8 is installed on the lower end of the connecting seat 7.

[0021] When in use, the staff first replaces the threaded sleeve 8 and the bolt mounting seat 11 according to the specifications of the threaded workpiece, first fixes the threaded sleeve 8 to the lower end of the connecting seat 7, fixes the bolt mounting seat 11 to the chuck 10, and then embeds the nut part of the threaded workpiece into the bolt mounting seat 11, and then drives the threaded workpiece to rotate at a uniform speed through the built-in motor 9, and then drives the linear module 3 on the rear side of the mounting plate 2 to drive the fixed frame 5 to move downward through the connecting frame 4 until the threaded sleeve 8 at the lower end of the connecting seat 7 is sleeved on the upper end of the threaded workpiece, and then drives the fixed frame 5 to move downward through the connecting frame 4. As the threaded workpiece rotates, the threaded sleeve 8 continues to move downward. If there are foreign objects on the external thread of the workpiece, it is damaged or the accuracy error is too large, the torque will be large or even stuck during the rotation detection process. At this time, the torque sensor 6 can read the torque value and transmit the signal to the external control computer to detect unqualified workpieces. After the detection is completed, the motor 9 rotates in the opposite direction to achieve the reverse rotation and disengagement of the workpiece. The overall degree of automation is relatively high, which is conducive to greatly reducing the labor intensity of human labor, ensuring the detection accuracy, avoiding the undesirable phenomenon of false detection, and at the same time improving the detection efficiency.

[0022] Further, the rotating mounting structure includes: a motor 9, a chuck 10, a bolt mounting seat 11 and a mounting hole 12;

[0023] The motor 9 is fixedly installed in the installation frame 1, and the driving end moves through the upper end of the installation frame 1. The chuck 10 is fixedly installed on the driving end of the motor 9. The bolt mounting seat 11 is installed on the upper end of the chuck 10, and the mounting hole 12 is opened at the center of the upper end of the bolt mounting seat 11.

[0024] When inspecting the workpiece, the bolt mounting seat 11 of the specified specification is fixed by the provided chuck 10, and the bottom end of the threaded workpiece is clamped and limited by the mounting hole 12 at the upper end of the bolt mounting seat 11. During the measurement process, the chuck 10, the bolt mounting seat 11 and the threaded workpiece are driven by the motor 9 to rotate at a uniform speed, and the external thread of the threaded workpiece is inspected in cooperation with the mobile detection structure.

[0025] Furthermore, a motor fixing bracket 13 is provided at the connection between the motor 9 and the mounting frame 1 .

[0026] Furthermore, a connecting support frame 14 is provided at the connection between the mounting upright plate 2 and the mounting frame 1 .

[0027] Furthermore, the chuck 10 is a three-jaw chuck 10 .

[0028] Furthermore, a mounting block 15 is provided at the connection between the torque sensor 6 and the fixed frame 5 .

[0029] The motor fixing frame 13 is used to stably support and fix the motor 9 to ensure the overall stability of the motor 9 during operation. The connection support frame 14 is set to effectively ensure the connection strength between the mounting plate 2 and the mounting frame 1, so that the central axis of the torque sensor 6 corresponds to the central axis of the motor 9. The three-jaw chuck 10 is used to realize the rapid installation of the bolt mounting seat 11. The mounting block 15 is set to effectively ensure the fixing strength of the torque sensor 6 to prevent the torque sensor 6 and the threaded sleeve 8 from rotating with the motor 9.
