[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-5This utility model provides an auxiliary device for hardness detection and positioning of nuts, including: a base plate 1 and a mounting bracket 2 installed on the top outer wall of the base plate 1, and further including: a rotating tube 3 rotatably installed on the top outer wall of the mounting bracket 2, a conductive slip ring 4 installed on the outer wall of the rotating tube 3, a driving component 5 installed on the top outer wall of the base plate 1, a lifting component 6 installed on the bottom inner wall of the rotating tube 3, and multiple equally spaced discs 7 installed on the outer wall of the rotating tube 3. Multiple equally spaced sliding grooves 8 are opened on the top outer wall of the discs 7, and a clamping component 9 is slidably connected to the inner wall of the sliding grooves 8. The bottom of the clamping component 9 is rotatably connected to the lifting component 6, and a driven wheel 10 is installed on the outer wall of the rotating tube 3.

[0015] It should be noted here that: Multiple nut placement: Multiple nuts 12 to be tested are placed on multiple discs 7 respectively, laying the foundation for batch testing.

[0016] Positioning and fixing: The lifting component 6 starts and descends, driving the clamping component 9, which is rotatably connected to it, to slide in the groove 8 of the disc 7. By changing the structure of the clamping component 9, the nut 12 is clamped, realizing the synchronous positioning of multiple nuts and ensuring that the nut position is accurate and the force is stable during testing.

[0017] Intermittent rotation sample delivery: The drive assembly 5 operates, and under the transmission action of the driven wheel 10, it drives the rotating tube 3 and the disc 7, clamping assembly 9 and nut 12 connected to the rotating tube 3 to rotate intermittently, and delivers the nut to be tested to the bottom of the detection head 11 in sequence.

[0018] Batch testing: During the pause of the rotating tube 3, the testing head 11 descends to test the hardness of the nut 12 at the current position. Unlike traditional devices that require "testing one and replacing one", batch testing can be carried out sequentially, improving efficiency. The conductive slip ring 4 solves the power supply problem of the lifting component 6 when the rotating tube 3 is rotating, ensuring the continuous and stable operation of the equipment.

[0019] In a preferred embodiment, the drive assembly 5 includes a geared motor 501, a drive wheel 502 mounted on the top of the geared motor 501, and a push rod 503 mounted on one end of the outer wall of the drive wheel 502.

[0020] It should be noted that after the geared motor 501 starts, it outputs power to drive the drive wheel 502 at its top to rotate. When the drive wheel 502 rotates, the push rod 503 at one end of its outer wall moves in a circular motion with the drive wheel 502. When the push rod 503 rotates to contact the driven wheel 10, it will push the driven wheel 10 to rotate at a certain angle. The drive wheel 502 continues to rotate, the push rod 503 separates from the driven wheel 10, and the driven wheel 10 stops rotating. This achieves the intermittent rotation of the driven wheel 10 and the rotating tube 3 connected to it, providing power for the sequential delivery of the nuts 12.

[0021] In a preferred embodiment, the lifting assembly 6 includes an electric push rod 601, a connecting plate 602 mounted on the top of the piston rod of the electric push rod 601, and a plurality of hexagonal prisms 603 equidistantly distributed on the top of the connecting plate 602.

[0022] It should be noted that after receiving a control signal, the electric push rod 601 extends and retracts downwards, causing the connecting plate 602 connected to the top to descend synchronously. As the connecting plate 602 descends, the multiple hexagonal prisms 603 mounted on its top descend along with it. During the descent of the hexagonal prisms 603, they generate a downward pulling or pushing force on the clamping assembly 9 rotatably connected to them, providing power for the clamping assembly 9 to slide within the slide groove 8 and clamp the nut 12. Furthermore, the multiple hexagonal prisms 603 are equidistantly distributed, allowing them to synchronously drive multiple clamping assemblies 9, ensuring that multiple nuts 12 are simultaneously positioned and fixed.

[0023] In a preferred embodiment, the clamping assembly 9 includes a slider 902, a traction rod 901 rotatably mounted on the bottom outer wall of the slider 902, and a clamping block 903 mounted on the top of the slider 902.

[0024] It should be noted that when the hexagonal prism 603 of the lifting assembly 6 descends, it pulls the bottom of the traction rod 901, which is rotatably connected to it, downwards. The traction rod 901 changes angle under force, and its top causes the slider 902, which is rotatably connected to it, to slide along the direction of the groove 8 in the disc 7. As the slider 902 slides, the clamping block 903 mounted on its top moves synchronously with it. The clamping blocks 903 of multiple clamping assemblies 9 move closer to each other, ultimately clamping the nut 12 placed on the disc 7, thus fixing the nut in place. Conversely, when the lifting assembly 6 rises, the traction rod 901 pushes the slider 902 and the clamping block 903 back to their original positions, releasing the nut 12.

[0025] In a preferred embodiment, one bottom end of the traction rod 901 is rotatably connected to the outer wall of the corresponding hexagonal prism 603.

[0026] It should be noted that this rotating connection method allows the traction rod 901 to rotate flexibly around the connection point on the outer wall of the hexagonal prism 603 when the hexagonal prism 603 is raised or lowered. This converts the linear raising and lowering motion of the hexagonal prism 603 into the angular rotation of the traction rod 901, which in turn drives the slider 902 to slide in the slide groove 8. This avoids motion interference and ensures that the power transmission from the lifting assembly 6 to the clamping assembly 9 is stable and smooth, ensuring that the clamping assembly 9 can reliably clamp or loosen the nut 12.

[0027] In a preferred embodiment, the electric actuator 601 is connected to the inner slip ring rotor of the conductive slip ring 4.

[0028] It should be noted that since the rotating tube 3 drives the lifting assembly 6 to rotate together, if the electric push rod 601 is directly powered by an external wire, the wire is prone to tangling and knotting during rotation. The inner slip ring rotor of the conductive slip ring 4 rotates synchronously with the rotating tube 3, while the outer slip ring stator remains stationary. The electric push rod 601, connected to the inner slip ring rotor, can achieve continuous power supply during rotation through the conductive slip ring 4. This ensures that the electric push rod 601 can still extend and retract normally during the rotation of the rotating tube 3, without affecting the lifting action and the positioning and fixing of the nut 12, thus ensuring the overall stable operation of the equipment.

[0029] Working principle: This device operates through the logic of "multi-nut synchronous positioning + intermittent rotation sampling + batch sequential testing," with each core component working together to achieve efficient positioning and testing. The specific principle is as follows: I. Overall Operation Process; Initial preparation: Place multiple nuts 12 to be tested at corresponding positions on multiple discs 7 on the outer wall of the rotating tube 3. The nut 12 on each disc 7 corresponds to the clamping component 9 in the slide groove 8.

[0030] Synchronous positioning and fixing: Start the lifting component 6, which drives the clamping component 9 to slide in the slide groove 8. Multiple clamping components 9 clamp the nut 12 simultaneously to ensure that the detection point of the nut 12 is accurately positioned and the force is stable.

[0031] Intermittent sample delivery: The drive assembly 5 operates, driving the rotating tube 3, disc 7, and nut 12 to rotate intermittently via the driven wheel 10, thereby sequentially delivering the nut 12 to be tested to the area below the test head 11.

[0032] Batch testing: During the pause of the rotating tube 3, the testing head 11 descends to perform hardness testing on the nut 12 at the current position; at the same time, the conductive slip ring 4 solves the power supply problem of the lifting assembly 6 when the rotating tube 3 is rotating, avoids wire tangling, and ensures continuous operation of the equipment.

[0033] II. Working principles of key components; Drive component 5: Provides intermittent rotational power; When the geared motor 501 is started, its output power drives the top drive wheel 502 to rotate, and the push rod 503 on the outer wall of the drive wheel 502 moves in a circular motion with the drive wheel 502.

[0034] When the push rod 503 rotates to contact the driven wheel 10, it pushes the driven wheel 10 to rotate at a certain angle; the drive wheel 502 continues to rotate, the push rod 503 separates from the driven wheel 10, the driven wheel 10 stops rotating, and thus realizes the intermittent rotation of the rotating tube 3, providing power for the nut 12 to feed samples in sequence.

[0035] Lifting component 6: Drives the clamping component to move; After receiving the control signal, the electric push rod 601 extends and retracts downward, causing the top connecting plate 602 to descend synchronously. The multiple hexagonal prisms 603 on the top of the connecting plate 602 descend together with the connecting plate 602.

[0036] When the hexagonal prism 603 descends, it exerts a downward force on the clamping component 9 connected to it, providing power for the clamping component 9 to clamp the nut 12; the multiple hexagonal prisms 603 are equidistantly distributed to ensure that the multiple clamping components 9 move synchronously and realize the synchronous positioning of multiple nuts 12.

[0037] Clamping component 9: clamps and fixes the nut; When the hexagonal prism 603 descends, it pulls the bottom of the traction rod 901, which is rotatably connected to it, to move downwards. The angle of the traction rod 901 changes, and its top drives the slider 902 to slide in the groove 8 of the disc 7.

[0038] When the slider 902 slides, the top clamping block 903 moves closer to the nut 12 in sync with the slider 902, and multiple clamping blocks 903 clamp the nut 12 together; conversely, when the piston rod of the electric push rod 601 rises, the traction rod 901 pushes the slider 902 and clamping block 903 to reset, and releases the nut 12.

[0039] The rotatable connection between the traction rod 901 and the hexagonal prism 603 can avoid motion interference and ensure that the linear motion of the hexagonal prism 603 is stably converted into the clamping / releasing action of the clamping assembly 9.

[0040] Conductive slip ring 4: Ensures power supply during rotation; The electric push rod 601 is connected to the inner slip ring rotor of the conductive slip ring 4 via a wire. When the rotating tube 3 rotates, the inner slip ring rotor rotates synchronously with the rotating tube 3, while the outer slip ring stator remains stationary.

[0041] This connection method enables continuous power supply to the electric push rod 601 while the rotating tube 3 is in operation, avoiding wire tangling and ensuring that the lifting component 6 can always drive the clamping component 9 normally during equipment operation.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
