[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] For example, see Figure 1-Figure 3 , an automatic flaw detection device for metal bars, comprising a base 100, a stabilizing seat 200 and a servo motor 300 are respectively mounted on the top of the base 100, a power rod 400 is transmission-connected to the side of the servo motor 300, a placement bin 500 is fixedly connected to the side of the power rod 400, a metal bar is passed through the stabilizing seat 200 and placed in the placement bin 500, and the servo motor 300 is activated to drive the power rod 400 transmission-connected to the servo motor 300 to rotate, so that the power rod 400 drives the placement bin 500 fixedly connected thereto to rotate, and drives the metal bar in the placement bin 500 to rotate; The outer side of the power rod 400 is fixedly connected with a sprocket wheel 1 601, and the outer side of the sprocket wheel 1 601 is equipped with a chain 602. The top of the base 100 is rotatably connected with a reciprocating screw rod 603, and the side of the reciprocating screw rod 603 is fixedly connected with a sprocket wheel 2 604. The top of the base 100 is slidably connected with a sliding block 605, which is assembled at the outer side of the reciprocating screw rod 603 and is connected to the reciprocating screw rod 603 through a thread. When the power rod 400 rotates, it can drive the sprocket wheel 1 601 fixedly connected thereto to rotate, and cooperate with the chain 602 assembled on the outer side of the sprocket wheel 1 601, so that the sprocket wheel 2 604 connected to the sprocket wheel 1 601 through the chain 602 rotates, and the sprocket wheel 2 604 drives the reciprocating screw rod 603 fixedly connected thereto to rotate, and the sliding block 605 assembled on the reciprocating screw rod 603 is restricted by the base 100, so that the sliding block 605 reciprocates in the horizontal direction.

[0019] The top of the sliding block 605 is fixedly connected to a fixed rod 606, the side of the fixed rod 606 is fixedly connected to an arc plate 607, the inside of the arc plate 607 is rotatably connected to a penetrating rotating rod 608, the outer side of the rotating rod 608 is fixedly connected to a gear 609, the top of the stabilizing seat 200 is fixedly connected to a gear rod 610, the gear rod 610 is located on the side of the gear 609 and is in a meshing state with the gear 609, and the bottom of the rotating rod 608 is equipped with a flaw detection needle body 611. When the sliding block 605 reciprocates in the horizontal direction, it can drive the fixed rod 606 connected thereto to move synchronously, so that the fixed rod 606 drives the arc plate 607 connected thereto to move, and the rotating rod 608 connected thereto to rotate and the gear 609 connected thereto to rotate synchronously, and because the gear 609 is restricted by the gear rod 610, the gear 609 rotates rapidly while moving horizontally, driving the rotating rod 608 connected thereto to rotate rapidly, so that the rotating rod 608 drives the flaw detection needle body 611 mounted on its bottom side to rotate, and the three flaw detection needle bodies 611 successively perform flaw detection operations on a certain point of the metal bar; and the flaw detection needle body 611 reciprocating in the horizontal direction cooperates with the rotating metal bar to perform flaw detection operations on various positions of the metal bar, thereby reducing the possibility of inaccurate detection results due to errors. The top of the base 100 is equipped with a stabilizing assembly 700 for clamping the metal bar, and the interior of the stabilizing seat 200 is equipped with an auxiliary stabilizing assembly 800 for adsorbing the metal bar.

[0020] When in use, the metal bar is passed through the stable seat 200 and placed in the placement bin 500, and the servo motor 300 is activated, which can drive the power rod 400 connected to the servo motor 300 to rotate, so that the power rod 400 drives the placement bin 500 fixedly connected thereto to rotate, and drives the metal bar located in the placement bin 500 to rotate. The power rod 400 also drives the sprocket wheel 1 601 fixedly connected thereto to rotate, and cooperates with the chain 602 assembled on the outside of the sprocket wheel 1 601 to rotate the sprocket wheel 2 604 connected to the sprocket wheel 1 601 through the chain 602, and the sprocket wheel 2 604 drives the reciprocating screw rod 603 fixedly connected thereto to rotate, and the sliding block 605 assembled on the reciprocating screw rod 603 is restricted by the base 100, so that the sliding block 605 reciprocates in the horizontal direction, and the sliding block 605 brings The fixed rod 606 fixedly connected thereto moves synchronously, so that the fixed rod 606 drives the arc plate 607 fixedly connected thereto to move, and the rotating rod 608 rotatably connected to the arc plate 607 and the gear 609 fixedly connected to the rotating rod 608 move synchronously therewith. Because the gear 609 is restricted by the gear rod 610, the gear 609 rotates rapidly while moving horizontally, driving the rotating rod 608 fixedly connected to the gear 609 to rotate rapidly, so that the rotating rod 608 drives the flaw detection needle body 611 assembled on its bottom side to rotate, and the three flaw detection needle bodies 611 successively perform flaw detection operations on certain points of the metal bar; and the flaw detection needle body 611 reciprocating in the horizontal direction cooperates with the rotating metal bar, so as to perform flaw detection operations on various positions of the metal bar.

[0021] For example 2, please refer to Figure 1-Figure 6 On the basis of the first embodiment, the stabilizing assembly 700 includes a hydraulic chamber 1 701 and a hydraulic device 702. The interior of the stabilizing seat 200 is connected to a clamping plate 704 by setting a spring 1 703. The interior of the hydraulic chamber 1 701 is connected to a movable block 706 by setting an elastic telescopic rod 1 705. The side of the hydraulic chamber 1 701 is slidably connected to an arc rod 707. After the metal bar passes through the stabilizing seat 200 and is placed in the placement chamber 500, the metal bar at one end away from the placement chamber 500 is clamped by two clamping plates 704. When the rotating rod 608 rotates rapidly, the hydraulic chamber 1 701 assembled on the outer side of the rotating rod 608 rotates rapidly accordingly. Under the action of centrifugal force, the movable block 706 in the hydraulic chamber 1 701 stretches the elastic telescopic rod 1 705 and slides in the hydraulic chamber 1 701, so that the pressure in the hydraulic chamber 1 701 increases, driving the arc rod 707 slidably connected to the hydraulic chamber 1 701 to move.

[0022] One end of the hydraulic device 702 is slidably connected to a force-bearing rod 708, which is located on the side of the arc rod 707 and in contact with the arc rod 707. The other end of the hydraulic device 702 is slidably connected to a push rod 709, and a spring 2 710 is installed on the side of the force-bearing rod 708. The side of the clamping plate 704 is connected to a force-bearing plate 712 by setting an elastic telescopic rod 2 711. The force-bearing plate 712 is located on the side of the push rod 709 and in contact with the push rod 709. When the arc rod 707 extends while rotating, it can squeeze the force rod 708 and drive the force rod 708 to move sideways, cooperate with the hydraulic device 702 slidably connected to the force rod 708, so that the pressure in the hydraulic device 702 increases, and drives the push rod 709 slidably connected to the hydraulic device 702 to move, and the push rod 709 then squeezes the force plate 712, so that the force plate 712 applies an additional force to the clamping plate 704 through the elastic telescopic rod 2 711. Improve the stability of the metal bar when being tested.

[0023] After the detection is completed, the rotating rod 608 stops rotating, and the centrifugal force cancels the restriction on the movable block 706. The movable block 706 is then reset under the action of the elastic telescopic rod 1 705, so that the arc rod 707 is reset. The arc rod 707 then cancels the restriction on the force-bearing rod 708, and the force-bearing rod 708 can be reset under the action of the spring 2 710, so that the stabilizing assembly 700 is reset, so as to facilitate the next use of the assembly.

[0024] When in use, on the basis of Example 1, after the metal rod is passed through the stabilizing seat 200 and placed in the placement bin 500, the metal rod at one end away from the placement bin 500 is clamped by the two clamping plates 704, and when the rotating rod 608 rotates rapidly, the hydraulic bin 1 701 assembled on the outside of the rotating rod 608 rotates rapidly accordingly, and the movable block 706 in the hydraulic bin 1 701 stretches the elastic telescopic rod 1 705 under the action of centrifugal force and slides in the hydraulic bin 1 701, so that the pressure in the hydraulic bin 1 701 increases, driving the arc rod 707 slidably connected to the hydraulic bin 1 701 to move, so that the arc rod 707 extends out while rotating, and the arc rod 707 then squeezes the force-bearing rod 708 and drives the force-bearing rod 708 to move sideways. Cooperating with the hydraulic device 702 that is slidably connected to the force-bearing rod 708, the pressure in the hydraulic device 702 increases, driving the push rod 709 that is slidably connected to the hydraulic device 702 to move, and the push rod 709 then squeezes the force-bearing plate 712, so that the force-bearing plate 712 applies an additional force to the clamping plate 704 through the elastic telescopic rod 2 711; after completing the detection, the rotating rod 608 stops rotating, and at this time, the centrifugal force cancels the restriction on the movable block 706, and the movable block 706 is then reset under the action of the elastic telescopic rod 1 705, thereby resetting the arc rod 707, and the arc rod 707 then cancels the restriction on the force-bearing rod 708, and the force-bearing rod 708 can be reset under the action of the spring 2 710, thereby resetting the stabilizing assembly 700.

[0025] For example 3, please refer to Figure 1-Figure 8 On the basis of the first and second embodiments, the auxiliary stabilizing assembly 800 includes a suction cup 801 mounted on the inner side of the clamping plate 704, a second hydraulic chamber 802 mounted on the side of the hydraulic device 702, and a connecting rod 803 slidably connected to the side of the second hydraulic chamber 802. When the metal bar is clamped by the two clamping plates 704, the suction cup 801 mounted on the clamping plates 704 immediately performs a preliminary suction operation on the metal bar, and when the pressure in the hydraulic device 702 increases, the pressure in the second hydraulic chamber 802 connected to the hydraulic device 702 can be increased synchronously, driving the connecting rod 803 slidably connected to the second hydraulic chamber 802 to move sideways.

[0026] The side of the suction cup 801 is equipped with a connected air pressure chamber 804, and the side of the air pressure chamber 804 is slidably connected with a pull rod 805, which is located at the top of the connecting rod 803 and is fixed to the connecting rod 803. When the connecting rod 803 moves to the side, the connecting rod 803 moves synchronously with the pull rod 805 fixedly connected thereto, and the air pressure chamber 804 slidably connected to the pull rod 805 can be used to extract the remaining gas between the suction cup 801 and the metal bar into the air pressure chamber 804 through the air pressure chamber 804. The suction of the suction cup 801 is made more stable, and the stability of the device during use is further improved. After the test is completed, when the stabilizing component 700 is reset, the pressure in the hydraulic device 702 is immediately restored to the initial state. Similarly, the gas in the air pressure chamber 804 can be re-injected between the suction cup 801 and the metal bar, so that the auxiliary stabilizing component 800 is reset. This is convenient for the next use of the component.

[0027] During use, on the basis of Embodiment 1 and Embodiment 2, when the metal bar is clamped by the two clamping plates 704, the suction cup 801 mounted on the clamping plate 704 immediately performs a preliminary adsorption operation on the metal bar, and when the pressure in the hydraulic device 702 increases, the pressure in the hydraulic chamber 2 802 connected to the hydraulic device 702 can be increased synchronously, driving the connecting rod 803 slidably connected to the hydraulic chamber 2 802 to move sideways, so that the connecting rod 803 moves synchronously with the pull rod 805 fixedly connected thereto, and cooperates with the air pressure chamber 804 slidably connected to the pull rod 805, so that the gas remaining between the suction cup 801 and the metal bar can be extracted into the air pressure chamber 804 through the air pressure chamber 804; after the detection is completed, when the stabilizing component 700 is reset, the pressure in the hydraulic device 702 immediately returns to the initial state, and similarly, the gas in the air pressure chamber 804 can be re-injected between the suction cup 801 and the metal bar, so that the auxiliary stabilizing component 800 is reset.
