Description

Technical Field

[0001] This utility model relates to an adsorption-type follow-up grinding device for automatic spectral detection of steel billets, belonging to the field of steel rolling spectral detection technology. Background Technology

[0002] To prevent steel mixing accidents, steel rolling mills require every steel billet put into production to undergo steel grade spectral identification. Spectral identification demands a smooth and clean test surface, necessitating grinding of the billet's test surface. However, many special steels have thick, hard oxide scale on their surfaces, often resulting in incomplete removal of the scale or uneven surface grinding during the process. This prevents the billet from maintaining perpendicularity to the grinding equipment, causing the grinding equipment to frequently retract or vibrate during grinding, compromising grinding efficiency and surface quality. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide an adsorption-type follow-up grinding device for automatic spectral detection of steel billets, which realizes the follow-up adsorption and posture adjustment of the grinding device, ensures that the grinding surface is perpendicular to the steel billet detection surface, solves the problem of the grinding device retraction and jumping under force, ensures the grinding effect of steel billets, and improves grinding efficiency.

[0004] The technical solution adopted by this utility model to solve the above problems is as follows: an adsorption-type follow-up grinding device for automatic spectral detection of steel billets, including a base, a connecting plate above the base, and a moving guide mechanism between the base and the connecting plate; a motor seat above the connecting plate, the motor seat being connected to the connecting plate through a rotating assembly; a motor is mounted on the motor seat, and the grinding device is mounted on the output shaft of the motor; two horizontal buffers are mounted at the end of the motor seat near the steel billet, the horizontal buffers being symmetrically arranged on both sides of the grinding device, and electromagnets are respectively mounted on the inner side of the horizontal buffers; the motor seat is connected to a cylinder through a push-pull rod, the cylinder driving the push-pull rod to move, causing the motor seat and the connecting plate to move along the guide rail, so that one horizontal buffer first contacts the steel billet, compresses it to generate a reverse force, and pushes the motor seat to swing horizontally around the rotating assembly, so that both horizontal buffers contact the surface of the steel billet together; the electromagnets are energized, and the electromagnets magnetically attract the steel billet.

[0005] The moving guide mechanism includes two parallel guide rails, each with a slider mounted on it, and a connecting plate fixed to the slider.

[0006] The rotating assembly includes a vertically arranged rotating shaft, a bearing seat is provided on the connecting plate, one end of the rotating shaft is located in the bearing seat, and the other end of the rotating shaft is fixed to the bottom of the motor base.

[0007] Two symmetrical rotary limiters are arranged on the base. The rotary limiters are located on both sides of the motor base and limit the swing angle of the motor base.

[0008] Compared with existing technologies, the advantages of this utility model are as follows: An adsorption-type follow-up grinding device for automatic spectral detection of steel billets uses a horizontal buffer in conjunction with an electromagnet to achieve follow-up adsorption and attitude adjustment of the grinding device, ensuring that the grinding surface is perpendicular to the steel billet detection surface. The electromagnet, combined with magnetic attraction to the steel billet, solves the problems of force-induced retraction and jumping of the grinding device, ensuring the grinding effect of the steel billet, while improving grinding efficiency and production efficiency.

Detailed Implementation

[0010] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0011] like Figure 1 , 2As shown, this embodiment of an adsorption-type follow-up grinding device for automatic spectral detection of steel billets includes a base 11. Two parallel guide rails 1 are mounted on the base 11, and sliders are respectively mounted on the guide rails 1. A connecting plate 2 is provided between the two sliders, and the connecting plate 2 is fixed to the sliders. The sliders can move along the guide rails 1, driving the connecting plate 2 to move synchronously. A parallel motor base 4 is provided above the connecting plate 2, and a horizontally arranged servo motor 7 is mounted on the motor base 4. The grinding device is mounted on the output shaft of the servo motor 7. The motor base 4 is connected to the connecting plate 2 via a rotating assembly. The motor base 4 can swing horizontally around the rotating assembly on the connecting plate 2, driving the grinding device to swing synchronously and adjusting the posture of the grinding device. Two horizontal buffers 5 are provided at the end of the motor base 4 near the steel billet, symmetrically arranged on both sides of the grinding device. Electromagnets 6 are respectively provided on the inner surface of the horizontal buffers 5. A horizontally arranged cylinder 10 is provided on the base 11. The extension rod of the cylinder 10 is connected to one end of a push-pull rod 9, and the other end of the push-pull rod 9 is connected to the motor base 4. Cylinder 10 drives push-pull rod 9 to move horizontally, causing motor base 4 and connecting plate 2 to move horizontally along guide rail 1, bringing horizontal buffer 5 closer to the billet. Horizontal buffer 5 is the first component to contact the billet surface, sensing the billet's contour and unevenness before the grinding device. The billet surface is usually uneven, possibly with curvature or inclination. Therefore, the two horizontal buffers will not contact the billet surface simultaneously. When one horizontal buffer touches the billet, it is compressed, generating a reverse force. This force acts on motor base 4, causing it to swing horizontally around the rotating assembly. This swing, triggered by the contact force of the horizontal buffers, continues until both horizontal buffers contact the billet surface and reach force balance, automatically adjusting the entire grinding device to a parallel position with the billet surface, ensuring the grinding surface is perpendicular to the detection surface. At this time, the two electromagnets 6 are energized, magnetically attracting the billet. The horizontal buffers and electromagnets work together to achieve follow-up attraction and attitude adjustment of the grinding device, ensuring the grinding surface is perpendicular to the detection surface and stable. After grinding is completed, the electromagnet is de-energized and released, the cylinder retracts, and the entire device is pulled back to its initial position.

[0012] The aforementioned rotating assembly includes a vertically arranged rotating shaft 3. One end of the rotating shaft is fixed to the bottom of the motor base, and a bearing seat is fixed on the base. The other end of the rotating shaft is set inside the bearing seat, so that the motor base and the rotating shaft swing within the bearing seat.

[0013] The aforementioned motor mount has limit plates on both sides, and rotation limiters are installed on both sides of the limit plates. When the motor mount swings to a preset maximum angle, the rotation limiters will collide with the limit plates. Through mechanical collision, the limit plates prevent the rotation limiters (and thus the motor mount) from continuing to rotate, thereby limiting the swing angle within a safe range. When the rotation limiters and limit plates work together, they limit the swing angle of the motor mount.

[0014] This application ensures that the grinding surface is perpendicular to the billet inspection surface. The electromagnet magnetically attracts the billet, solving the problems of force retraction and jumping of the grinding device, thus guaranteeing the grinding effect of the billet and improving grinding efficiency and production efficiency.

[0015] In addition to the above embodiments, this utility model also includes other implementation methods. All technical solutions formed by equivalent transformation or equivalent substitution should fall within the protection scope of the claims of this utility model.
