TECHNICAL FIELD

[0001] The utility model relates to detection technical field especially relates to a stopper rod head detection device. BACKGROUND

[0002] In the continuous casting process, the stopper rod is used as the flow control product to control the flow of the molten steel from the tundish into the crystallizer, and plays a crucial role in the stability of the liquid surface of the crystallizer and the stability of the casting speed, especially the cooperation between the stopper rod head and the upper nozzle of the tundish needs to be precisely controlled, so whether the size and shape of the stopper rod head are consistent with the drawing is particularly important.

[0003] The existing measurement of the stopper rod head only measures the length and diameter of the rod head, and the curvature and diameter of the arc surface or the conical surface of the stopper rod head cannot be measured.

[0004] Therefore, it is urgent to design a new stopper rod head detection device to improve the above problems. UTILITY MODEL CONTENT

[0005] The utility model aims at providing a stopper rod head detection device to solve the technical problem that the curvature and diameter of the arc surface or the conical surface of the stopper rod head cannot be measured.

[0006] To achieve this purpose, the utility model adopts the following technical solutions:

[0007] The utility model provides a stopper rod head detection device, which comprises:

[0008] The head type template is provided with a groove, the shape of the groove is matched with the shape of the stopper rod head, and a through hole penetrating through the head type template is formed in the inner wall of the groove.

[0009] The detection piece is arranged in the through hole, the length of the detection piece is greater than the length of the through hole, one end of the detection piece is movably inserted into the groove or located in the through hole, and the other end of the detection piece is located outside the through hole.

[0010] By inserting the stopper rod head to be detected into the groove of the head type template and rotating, the head of the stopper rod head abuts against one end of the detection piece inserted into the through hole, and the other end of the detection piece will be inserted into the through hole. The operator can judge whether the head type of the stopper rod head meets the drawing standard through the extension length of the detection piece, whether the stopper rod head can be inserted into the groove, and the gap between the stopper rod head and the groove after insertion, so as to judge whether the diameter of the stopper rod head meets the standard, so that the stopper rod head detection device can measure the curvature and diameter of the arc surface or the conical surface of the stopper rod head, and the structure is simple and the detection process is convenient and convenient.

[0011] As a preferred embodiment of the stopper rod head detection device, the head-shaped template is placed horizontally, the groove is located at the bottom of the head-shaped template, and the axial direction of the perforation is set in the vertical direction.

[0012] After the stopper head disengages from the groove, the test piece can move downwards within the perforation by its own weight, allowing one end of the test piece to extend into the groove. The test piece automatically resets without manual operation, facilitating the testing of the next stopper head and increasing testing efficiency.

[0013] As a preferred embodiment of the stopper rod head detection device, a limiting element is provided at the end of the detection element away from the groove.

[0014] The diameter of the limiting component is larger than the diameter of the perforation. The limiting component abuts against the top of the head-shaped template, which can prevent the detection component from falling out of the perforation, thus ensuring high reliability.

[0015] As a preferred embodiment of the stopper rod head detection device, the through hole is a threaded hole, and the detection element includes:

[0016] A screw rod, which is threaded into the threaded hole.

[0017] The screw rod is connected to the head template via a threaded connection, which improves the overall integrity of the screw rod and the head template, facilitates replacement or relocation, and reduces the chance of the screw rod being accidentally lost.

[0018] As a preferred embodiment of the stopper rod head detection device, the perforation is a circular hole, and the detection element includes:

[0019] A round rod, which passes through the round hole.

[0020] The round rod is connected to the head template through a connector, which allows for a more direct and accurate determination of whether the stopper head meets the standard by the vertical movement of the round rod within the perforation.

[0021] As a preferred embodiment of the stopper rod head detection device, the cross-sectional shape of the groove is an arc-shaped surface, a conical surface, or a hemispherical surface.

[0022] The shape of the groove can be set according to the shape of the stopper head to be tested, which is highly adaptable.

[0023] As a preferred embodiment of the stopper rod head detection device, the midpoint of the arc-shaped surface of the groove, the center of the conical surface, or the center point of the hemispherical surface is located on the axial direction of the perforation.

[0024] The groove is recessed in the same direction as the axial direction of the perforation, so that the head of the stopper rod can cover the entire arc surface of the head during the rotation of the stopper rod in the groove, thereby enabling the detection of the curvature of the arc surface, conical surface or hemispherical surface.

[0025] As a preferred embodiment of the stopper rod head detection device, a mark is provided on the periphery of the end of the detection element away from the groove.

[0026] The markings allow operators to more intuitively see whether the stopper head meets the standards.

[0027] As a preferred embodiment of the stopper rod head detection device, the edge of the groove of the head template is provided with a slot.

[0028] The rod of the stopper head is inserted into the slot, and the edge of the end abuts against the connecting edge of the slot and groove to limit the insertion depth of the rod. This prevents the stopper head from being inserted too deeply, improves the detection accuracy, and protects the head of the stopper head.

[0029] The beneficial effects of this utility model are:

[0030] By inserting the stopper rod head into the groove of the head-shaped template and rotating it, one end of the stopper rod head abuts against the test piece and extends into the through hole, while the other end of the test piece extends out of the through hole. The operator can determine whether the head shape of the stopper rod head conforms to the drawing standard by observing the extension length of the test piece. By observing whether the stopper rod head can be inserted into the groove and the gap between the stopper rod head and the groove after insertion, the operator can determine whether the diameter of the stopper rod head conforms to the standard. Thus, the stopper rod head testing device can measure the curvature and diameter of the arc or conical surface of the stopper rod head. The structure is simple and the testing process is convenient and easy. Attached Figure Description

[0036] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0037] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0038] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0039] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0040] In the continuous casting process, the stopper rod, as a flow control product that controls the flow of steel from the tundish into the crystallizer, plays a crucial role in stabilizing the liquid level and casting speed in the crystallizer. Existing measurements of the stopper rod head only measure the length and diameter of the rod head, and cannot measure the curvature and diameter of the arc or conical surface of the stopper rod head.

[0041] Example 1

[0042] To solve the above problems, combined with Figure 1 As shown, this embodiment provides a stopper rod head detection device, including a head-shaped template 1 and a detection element 2. The head-shaped template 1 is provided with a groove 11, the shape of which matches the shape of the stopper rod head. A through hole 12 is provided on the inner wall of the groove 11, penetrating the head-shaped template 1. The detection element 2 is disposed in the through hole 12, and the length of the detection element 2 is greater than the length of the through hole 12. One end of the detection element 2 extends movably into the groove 11 or is located in the through hole 12, and the other end of the detection element 2 is located outside the through hole 12.

[0043] Understandably, by inserting the stopper rod head to be tested into the groove 11 of the head template 1 and rotating it, one end of the stopper rod head abutting against the test piece 2 extends into the through hole 12, and the other end of the test piece 2 extends out of the through hole 12. The operator can determine whether the head shape of the stopper rod head conforms to the drawing standard by observing the extension length of the test piece 2. By observing whether the stopper rod head can be inserted into the groove 11 and the gap between the stopper rod head and the groove 11 after insertion, the operator can determine whether the diameter of the stopper rod head conforms to the standard. Thus, the stopper rod head testing device can measure the curvature and diameter of the arc or conical surface of the stopper rod head. The structure is simple and the testing process is convenient and easy.

[0044] In this embodiment, the head-shaped template 1 is preferably a steel sheet. The head-shaped template 1 is placed horizontally, the groove 11 is located at the bottom of the head-shaped template 1, and the axial direction of the through hole 12 is set in the vertical direction. After the stopper rod head is disengaged from the groove 11, the detection element 2 can move downward in the through hole 12 by its own weight, so that one end of the detection element 2 extends into the groove 11. The detection element 2 automatically resets without manual operation, which facilitates the detection of the next stopper rod head and improves the detection efficiency.

[0045] To prevent test piece 2 from detaching from the perforation 12, see [reference needed]. Figure 1 A limiting member 3 is provided at the end of the detection piece 2 away from the groove 11. The diameter of the limiting member 3 is larger than the diameter of the hole 12. That is, the detection piece 2 and the limiting member 3 are arranged in a "T" shape. The limiting member 3 abuts against the top of the head template 1, which can prevent the detection piece 2 from coming out of the hole 12 and has good reliability.

[0046] Specifically, in this embodiment, the through hole 12 is a threaded hole, and the detection component 2 includes a screw rod. The screw rod is threaded into the threaded hole and connected to the head template 1 through the threaded connection, which makes the screw rod and the head template 1 more integrated, facilitates replacement or transfer, and reduces the possibility of the screw rod being accidentally lost.

[0047] Optionally, the cross-sectional shape of the groove 11 can be an arc-shaped surface, a conical surface, or a hemispherical surface, etc. In this embodiment, the shape of the groove 11 is not limited. The shape of the groove 11 can be set according to the shape of the stopper rod head to be tested, which has good adaptability.

[0048] Furthermore, in this embodiment, the number of grooves 11 on the head-shaped template 1 is one, which helps the operator concentrate on judging the test results. Of course, in other embodiments, there can be two, three, or even more grooves. Setting multiple grooves allows for the simultaneous testing of multiple stopper heads, resulting in higher testing efficiency. This embodiment does not limit the specific number.

[0049] Furthermore, the midpoint of the arcuate surface, the center of the conical surface, or the center of the hemispherical surface of the groove 11 is located on the axial direction of the perforation 12. The recessed direction of the groove 11 is on the same straight line as the axial direction of the perforation 12, so that the head of the stopper rod can cover the entire arcuate surface of the head during the rotation of the stopper rod within the groove 11, thereby enabling the detection of the curvature of the arcuate surface, conical surface, or hemispherical surface.

[0050] To enable operators to more intuitively see the test results of the stopper rod head, a mark 21 is provided on the periphery of the end of the test piece 2 away from the groove 11. Preferably, the mark 21 is colored paint applied to the periphery of the screw rod, or it can be an adhesive strip adhered to the periphery of the screw rod.

[0051] In addition, the groove 11 of the head template 1 is provided with a slot 13 on the edge. The rod of the stopper rod head is inserted into the slot 13 and the end edge abuts against the connecting edge of the slot 13 and the groove 11 to limit the insertion depth of the rod. This can prevent the insertion depth of the stopper rod head from being too deep, improve the detection accuracy, and protect the head of the stopper rod head.

[0052] Now combined Figure 1 The testing process for the stopper rod head is explained below:

[0053] One end of the adjusting screw rod passes through the through hole 12 and extends into the groove 11. The head of the stopper rod to be tested is inserted into the groove 11. During the insertion process, the head of the stopper rod rotates and advances until the rod of the stopper rod abuts against the slot 13. Its head pushes one end of the screw rod into the through hole 12. The operator observes the mark 21 on the other end of the screw rod and the gap between the head of the stopper rod and the groove 11. Based on the mark 21 and the gap, the operator judges whether the head of the stopper rod meets the drawing standard.

[0054] Example 2

[0055] The structures of Embodiment 1 and Embodiment 2 are basically the same, except that the perforation 12 is a round hole and the detection component 2 includes a round rod that passes through the round hole. The round rod is connected to the head template 1 through a connector, which can more directly and accurately determine whether the stopper rod head meets the standard by the vertical movement of the round rod in the perforation 12.

[0056] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model.
