Description

Technical Field

[0001] This utility model relates to the technical field of continuous casting roll processing equipment, and in particular to an automatic clamping device for continuous casting rolls. Background Technology

[0002] The continuous casting roll is the most critical component on the continuous casting machine. It bears the weight and drives the billet and the movable mold. During the processing of the continuous casting roll, a clamping device is needed to fix the continuous casting roll, and then it works together with the processing equipment.

[0003] Current clamping devices typically rely on manual operation, which is cumbersome and has low precision, failing to meet requirements. Furthermore, they are limited in function, only able to fix the continuous casting roll. If the orientation of the continuous casting roll needs to be changed during subsequent processing, the fixing operation needs to be repeated, making processing inconvenient. In addition, they have poor applicability to continuous casting rolls of different specifications. Utility Model Content

[0004] Based on the above problems, the purpose of this utility model is to provide an automatic clamping device for continuous casting rolls, which improves the automation, convenience and versatility of clamping continuous casting roll workpieces.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] An automatic clamping device for continuous casting rolls includes a frame base, a spindle box mounted on the frame base, a rotary chuck mounted on the spindle box, a first mounting plate clamped on the rotary chuck, a movable tailstock mounted on the frame base and located on one side of the spindle box, the movable tailstock being driven by an adjustment component to move closer to and away from the rotary chuck, a rotatable second mounting plate mounted on the movable tailstock, the first mounting plate and the second mounting plate being coaxially and oppositely arranged, and adapter plates being respectively provided on the opposite surfaces of the first mounting plate and the second mounting plate, with a roll sleeve adapted to the end of the continuous casting roll workpiece to be clamped on the adapter plate.

[0007] As an alternative, both the first and second mounting plates include a clamping part and a mounting plate surface, and the mounting plate surface of at least one of the first and second mounting plates can float axially relative to the clamping part. The clamping part is held by a rotary chuck or rotatably mounted on a movable tailstock, and the adapter plate is fixed to the mounting plate surface.

[0008] As an alternative, the adjustment assembly includes a slide rail mounted on the frame base and a rack parallel to the slide rail. The slide rail extends from the spindle box to the movable tailstock. A slide block is mounted on the slide rail, and the movable tailstock is mounted on the slide block. The slide block is equipped with a first drive motor, and a first gear that meshes with the rack is mounted on the output shaft of the first drive motor.

[0009] As an alternative, the bottom of the slide is provided with a second gear that engages with the rack.

[0010] As an alternative, a slewing bearing is provided on the spindle box housing, a rotary chuck is mounted on the slewing bearing, an external gear ring is provided on the slewing bearing, a second drive motor is provided in the spindle box, the output end of the second drive motor extends out of the spindle box housing and is provided with a third gear that mates with the external gear ring.

[0011] As an alternative, a third drive motor is provided on the movable tailstock, which is used to drive the second mounting plate to rotate synchronously in opposite directions with the first mounting plate.

Detailed Implementation

[0019] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar parts or parts having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0020] 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 or a detachable connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or 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 according to the specific circumstances.

[0021] In the description of this utility model, unless otherwise expressly 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," "on the upper side," and "over" the second feature include 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 include 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.

[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] like Figure 1 and Figure 2 As shown, this utility model provides an automatic clamping device for continuous casting rolls, including a frame base 1, a spindle box 2 on the frame base 1, a rotary chuck 3 on the spindle box 2, a first mounting plate 4 clamped on the rotary chuck 3, a movable tailstock 5 on the frame base 1 and located on one side of the spindle box 2, the movable tailstock 5 being driven by an adjustment component to move closer to and away from the rotary chuck 3, a rotatable second mounting plate 6 on the movable tailstock 5, the first mounting plate 4 and the second mounting plate 6 being coaxially and oppositely arranged, and a transition plate 7 being respectively provided on the opposite surfaces of the first mounting plate 4 and the second mounting plate 6, the transition plate 7 being provided with a roller sleeve 8 adapted to the end of the continuous casting roll workpiece to be clamped.

[0024] Thus, the continuous casting roll workpiece is reliably clamped by the roller sleeves 8 on the first mounting plate 4 and the second mounting plate 6, which can move relatively and rotate synchronously. This improves the automation and efficiency of clamping, and ensures that the posture of the continuous casting roll workpiece can be flexibly adjusted during the processing. It also enhances the adaptability to continuous casting roll workpieces of different specifications. Only the roller sleeves 8 of the corresponding specifications need to be replaced, which provides reliable support for the efficient and precise processing of continuous casting rolls.

[0025] In at least one embodiment, both the first mounting plate 4 and the second mounting plate 6 include a clamping part and a mounting plate surface, and the mounting plate surface of at least one of the first mounting plate 4 and the second mounting plate 6 can float axially relative to the clamping part. The clamping part is held by a rotating chuck 3 or rotated on the movable tailstock 5, and the adapter plate 7 is fixed on the mounting plate surface.

[0026] The floating design provides a certain amount of buffer and pre-tightening force when clamping the continuous casting roll workpiece, avoiding damage from hard contact. The specific floating structure can be implemented in various ways, such as by setting a spring in the clamping part, inserting the center of the mounting plate into the clamping part and abutting against the spring, so as to achieve axial floating of the mounting plate relative to the clamping part.

[0027] To enable the movable tailstock 5 to translate relative to the spindle box 2, the adjustment assembly includes a slide rail 9 and a rack 10 parallel to the slide rail 9, which are mounted on the frame base 1. The slide rail 9 extends from the spindle box 2 to the movable tailstock 5. A slide block 11 is mounted on the slide rail 9. The movable tailstock 5 is mounted on the slide block 11. A first drive motor 12 is mounted on the slide block 11. A first gear 13 that meshes with the rack 10 is mounted on the output shaft of the first drive motor 12.

[0028] The adjustment of the movable tailstock 5 is transformed from traditional manual, experience-based operation to precise linear displacement controlled by a motor. The first drive motor 12 drives the first gear 13 to mesh with the rack 10, so that the movable tailstock 5 can move quickly and accurately along the slide rail 9 to the predetermined position and lock reliably, which improves the displacement accuracy and simplifies the operation.

[0029] Furthermore, a second gear 14 that engages with the rack 10 is provided at the bottom of the slide 11.

[0030] Adding a second gear 14 to the first gear 13 is a design to enhance stability. It effectively resists the overturning moment generated by the weight of the continuous casting roll workpiece, ensuring that the slide 11 does not jam or deviate during long-stroke movement, thus guaranteeing the long-term rigidity and repeatability of the device.

[0031] Optionally, a slewing bearing 15 is provided on the housing of the spindle box 2, a rotary chuck 3 is mounted on the slewing bearing 15, an external gear ring 16 is provided on the slewing bearing 15, a second drive motor 17 is provided in the spindle box 2, the output end of the second drive motor 17 extends out of the housing of the spindle box 2 and is provided with a third gear 18 that cooperates with the external gear ring 16.

[0032] The slewing bearing 15 is a large bearing specifically designed to withstand large axial loads, radial loads, and overturning moments. The slewing bearing 15 with an external gear ring 16 and driven by a second drive motor 17 can provide extremely smooth and powerful rotational motion for the continuous casting roll workpiece, making it particularly suitable for heavy workpiece processing scenarios that require high torque and low speed.

[0033] Optionally, a third drive motor 19 is provided on the movable tailstock 5, which is used to drive the second mounting plate 6 to rotate synchronously in opposite directions with the first mounting plate 4.

[0034] By adding a third drive motor 19 to the moving tailstock 5, the second mounting plate 6 also has a rotation function. Thus, when adjusting the circumferential angle of the continuous casting roll workpiece, the force couple is balanced, and the continuous casting roll workpiece will not bear additional torsional stress, making the adjustment operation smoother and more precise, which is especially beneficial for complex processes that require indexing.

[0035] Optionally, the roller sleeve 8 is provided with a boss that can be inserted into the end hole of the continuous casting roll workpiece, and a buffer washer 20 is fitted on the boss.

[0036] The fit between the boss and the end hole of the continuous casting roll body achieves precise centering, while the buffer washer 20 fitted on the boss plays multiple positive roles: first, it absorbs vibrations during processing and improves surface quality; second, it allows for minor radial deformation and compensates for dimensional tolerances; and third, it avoids rigid impacts between metal parts and protects the surface of the continuous casting roll workpiece.

[0037] In summary, this automatic clamping device for continuous casting rolls effectively solves the problems of cumbersome operation, insufficient precision, single function, and poor adaptability of traditional clamping devices by integrating multiple designs such as floating centering, precision linear drive, double gear anti-tipping, high torque rotation, and synchronous drive. Its highly automated clamping and adjustment capabilities significantly improve the positioning accuracy, stability, and operating efficiency of continuous casting roll processing, providing a reliable equipment foundation for achieving efficient, high-quality, and intelligent processing of continuous casting rolls.

[0038] 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 other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
