The rotation of the threaded rod causes the transmission block to move downward along the outer surface of the threaded rod. The transmission block then drives the detection head to move downward for sensory inspection. At the same time, the rotation of the worm gear drives the worm wheel to rotate, causing the stroke column on the front surface of the worm wheel to press against the inner wall of the stroke groove. This forces the stroke component to pull the sliding plate along the inner wall of the sliding groove towards the steel pipe. The sliding plate then drives the arc plate towards the steel pipe until the arc plate fixes the steel pipe, achieving the effect of automatically stabilizing and inspecting the steel pipe.

[0046] Arc plate 501: The opposite side of arc plate 501 is attached to the outer surface of steel pipe 4;

[0047] Sliding rod 502: One end of the sliding rod 502 is fixedly connected to the opposite side of the arc plate 501;

[0048] Telescopic spring 503: The telescopic spring 503 is sleeved on the outer surface of the sliding rod 502, and one end of the telescopic spring 503 is fixedly connected to the opposite side of the arc plate 501;

[0049] Sliding plate 504: The interior of sliding plate 504 is slidably connected to the outer surface of sliding rod 502, and the opposite side of sliding plate 504 is fixedly connected to the opposite end of telescopic spring 503.

[0050] refer to Figure 2 As shown, the upper surface of the workbench 3 is provided with a sliding groove 6. There are two sliding grooves 6, and the inner walls of the two sliding grooves 6 are slidably connected to the outer surface of the sliding plate 504.

[0051] Using the above scheme: the sliding plate 504 moves along the inner wall of the sliding groove 6 to the opposite side, the sliding plate 504 drives the sliding rod 502 and the telescopic spring 503 to move to the opposite side, and the sliding rod 502 drives the arc plate 501 to approach the steel pipe 4 until the opposite side of the arc plate 501 is in close contact with the outer surface of the steel pipe 4.

[0052] refer to Figure 3As shown, a stroke assembly 7 is provided on the opposite side of the sliding plate 504. There are two stroke assemblies 7, and the two stroke assemblies 7 include:

[0053] Stroke component 701: The opposite side of stroke component 701 is fixedly connected to the opposite side of sliding plate 504;

[0054] Stroke groove 702: Stroke groove 702 is formed on the surface of stroke component 701;

[0055] Stroke column 703: The outer surface of stroke column 703 is slidably connected to the inner wall of stroke groove 702, and a transmission component 8 is provided on the rear end face of stroke column 703.

[0056] Using the above scheme: In order to move the sliding plate 504 to the opposite side, the stroke column 703 moves in a circular trajectory. The outer surface of the stroke column 703 can press against the inner wall of the stroke groove 702 and slide along the inner wall of the stroke groove 702, so that the stroke member 701 pulls the sliding plate 504 to the opposite side.

[0057] refer to Figure 3 As shown, the transmission assembly 8 includes:

[0058] Worm Gear 801: There are two worm gears 801, and the front surfaces of both worm gears 801 are fixedly connected to the rear end face of the stroke column 703;

[0061] The above scheme is adopted: In order to make the stroke column 703 move in a circular trajectory, the worm 802 rotates, and the outer surface of the worm 802 meshes with the outer surface of the worm wheel 801, so that the worm wheel 801 rotates. The worm wheel 801 then drives the stroke column 703 on the front surface to move. The support rod 803 mainly plays the role of supporting the worm wheel 801.

[0062] refer to Figure 4 As shown, the driving component 9 includes:

[0063] Motor 901: The output end of motor 901 is fixedly connected to the lower surface of worm 802, and the lower surface of motor 901 is fixedly connected to the inside of the main body 1;

[0064] Pulley 902: There are two pulleys 902, which are connected by belt drive. The front pulley 902 is fixedly connected to the outer surface of the output end of the motor 901.

[0065] Using the above scheme: In order to make the worm 802 rotate, the motor 901 is started. The output end of the motor 901 can drive the worm 802 to rotate. At the same time, it drives the front pulley 902 to rotate. The front pulley 902 drives the rear pulley 902 to rotate through the belt.

[0066] refer to Figure 4 As shown, a lifting assembly 10 is provided on the upper surface of the rear pulley 902. The lifting assembly 10 includes:

[0067] Threaded rod 1001: The lower end face of threaded rod 1001 is fixedly connected to the upper surface of the rear pulley 902, and the upper end face of threaded rod 1001 is rotatably connected to the inside of the main body 1 through a rotating shaft;

[0068] Transmission block 1002: The transmission block 1002 is internally connected to the threaded rod 1001 via a threaded rotation, and the front surface of the transmission block 1002 is fixedly connected to the rear surface of the detection head 2.

[0069] Using the above scheme: When the rear pulley 902 rotates, the rear pulley 902 can drive the threaded rod 1001 to rotate. The threaded rod 1001 is connected to the transmission block 1002 through the threaded rotation, so that the transmission block 1002 moves downward along the outer surface of the threaded rod 1001. The transmission block 1002 can drive the detection head 2 to move downward until the detection head 2 contacts the outer surface of the steel pipe 4.

[0070] refer to Figure 2 As shown, a limiting groove 11 is provided on the front surface of the main body 1, and the inner wall of the limiting groove 11 is slidably connected to the outer surface of the transmission block 1002.

[0071] Using the above scheme: The limiting groove 11 mainly serves to provide a moving path for the transmission block 1002 to drive the detection head 2 to move downward.

[0072] The working principle of this utility model:

[0073] In operation, starting the motor 901 causes the output of the motor 901 to drive the worm gear 802 to rotate. Simultaneously, this drives the front pulley 902 to rotate, which in turn drives the rear pulley 902 via a belt. The rotation of the front pulley 902, in turn, drives the worm gear 802 to rotate. The outer surface of the worm gear 802 meshes with the outer surface of the worm wheel 801, causing the worm wheel 801 to rotate. The worm wheel 801 then drives the stroke column 703 on the front surface to move in a circular path. The outer surface of the stroke column 703 can press against the inner wall of the stroke groove 702 and slide along it, causing the stroke component 701 to pull the sliding plate 504 along the sliding groove. The inner wall of the moving groove 6 moves to the opposite side, and the sliding plate 504 drives the sliding rod 502 and the telescopic spring 503 to move to the opposite side. The sliding rod 502 then drives the arc plate 501 to move closer to the steel pipe 4 until the opposite side of the arc plate 501 is in close contact with the outer surface of the steel pipe 4. At the same time, the rear pulley 902 rotates, driving the threaded rod 1001 to rotate. The threaded rod 1001 is connected to the transmission block 1002 through the threaded rotation, so that the transmission block 1002 moves downward along the outer surface of the threaded rod 1001. The transmission block 1002 can drive the detection head 2 to move downward until the detection head 2 contacts the outer surface of the steel pipe 4, and perform hardness testing on the steel pipe 4.

[0074] In summary, this steel pipe hardness testing instrument, comprising a main body 1, a testing head 2, a worktable 3, a steel pipe 4, a stabilizing component 5, a sliding groove 6, a stroke component 7, a transmission component 8, a drive component 9, a lifting component 10, and a limiting groove 11, solves the problem that the lack of a limiting and stabilizing component in the equipment necessitates manual fixing of the steel pipe by the operator, while the operator's other hand needs to control the downward movement of the testing head to contact the steel pipe for testing, which greatly increases the error in testing accuracy.
