[0021] In this embodiment, by cooperating with each other between the six array-distributed positioning slots 11 and the positioning plates 30, the lengths of multiple groups of bolts can be synchronously detected at one time, thereby improving detection efficiency, reducing repeated operation processes, and saving labor costs.

[0022] In this embodiment, the two corresponding movable blocks 13 and the limiting clamping plates 8 are brought close to each other and guided by the limiting grooves 15, thereby limiting the position of the bolts and adapting to bolts of different diameters to ensure stability during the length detection process.

[0023] In this embodiment, the elastic telescopic rod 28 cooperates with the return spring 29 and the positioning plate 30 to press down the top of the bolt, and cooperates with the benchmark 25 for comparison to quickly detect the length of the bolt and intuitively and efficiently reflect the deviation of the bolt length.

[0024] In this embodiment, the slider 24 is guided by the first slide groove 18, and the connecting plate 22 is doubly limited by the slide rod 20 and the second slide groove 21 to eliminate movement deviation, ensure that the positioning plate is pressed vertically, and improve measurement repeatability accuracy.

[0025] In this embodiment, the electric slide rail 23 drives the benchmark 25 as a mechanical limit standard component, and moves the benchmark 25 to a corresponding position as a standard for length detection, without the need for repeated adjustments by staff, which is convenient for operation.

[0026] In this embodiment, the rubber pad 14 provides a flexible contact surface to prevent the bolt surface from being scratched due to excessive strength during the clamping process.

[0027] In this embodiment, the laser level 3 and the benchmark 25 are used as a dual reference to improve the accuracy of detecting the bolt length.

[0028] In this embodiment, the vacuum cleaner 4 drives the vacuum head 26 and the vacuum tube 7 to work, and automatically removes metal debris in the bolt thread during the detection process to prevent the debris from interfering with the measurement results.

[0029] The working principle and usage process of the present invention: After the present invention is installed, the electromagnet 10 is energized to generate magnetic force, and then the bolts whose lengths need to be detected are respectively placed in the corresponding positioning grooves 7, and the first motor 9 is started to drive the bidirectional threaded rotating shaft 12 to rotate, thereby driving the movable block 13 to move within the limit selection of the limit groove 15, and then driving the limit splint 8 and the rubber pad 14 to move closer to each other, and the position of the bolt is limited by the full contact between the limit splint 8 and the rubber pad 14 and the surface of the bolt, and the laser level 3 is started to generate laser, and the electric slide 23 is started, and the benchmark 25 is moved to the position corresponding to the laser through the electric slide 23, and then the electric slide 23 is turned off, and the vacuum cleaner 4 is started to drive the vacuum head 26 and the vacuum tube 7 to move the surface of the bolt Dust and debris are sucked into the interior of the dust collection box 5, and the second motor 16 is started, causing it to drive the threaded rotating shaft 17 to rotate, thereby driving the slider 24 to move under the restriction of the first slide groove 18, and then driving the connecting plate 22 to move under the restriction of the slide rod 20 and the second slide groove 21, thereby driving the elastic telescopic rod 28 and the positioning plate 20 to press down. After the positioning plate 30 contacts the bolt, the bolt will push up the positioning plate 20, causing the return spring 29 to contract, thereby driving the elastic telescopic rod 28 to contract, and observe whether the positioning plate 30 is at the same height as the laser and the benchmark 25. If the positioning plate 30 is above the benchmark 25 and the laser, it means that the bolt is too long, otherwise it means that the bolt is too short. All electrical equipment in this device is powered by an external power supply, and all motors or electric push rods in this article are controlled by a PLC control system.

[0030] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention.
