Description

Technical Field

[0001] This utility model relates to the field of rolling mill drilling technology, and in particular to a center drilling device for rolling mill production. Background Technology

[0002] Center drilling equipment for roll production is an indispensable key piece of equipment in the roll manufacturing process. It is mainly used to machine a precise center hole at the axial position of the roll blank, laying the foundation for subsequent processing steps. It is widely used in the production of various types of rolls, whether hot or cold rolled, all of which require the processing of center drilling equipment. It can automatically adapt the corresponding drilling speed and feed rate according to the material and specifications of the roll, reducing errors caused by manual intervention, effectively ensuring the perpendicularity and coaxiality of the center hole, providing a reliable positioning reference for subsequent turning, grinding and other processing steps of the roll, improving production efficiency, reducing safety risks in the production process, and meeting the dual requirements of precision and efficiency in roll production.

[0003] In roll processing, the positioning mechanism is the core to ensure the accuracy of center drilling. Traditional positioning devices mostly use a single clamping method, which has poor adaptability to rolls of different diameters and is prone to loosening due to insufficient contact area. In addition, the limiting structure is simple and axial offset is prone to occur during processing. At the same time, the fixing process relies on manual adjustment, which is cumbersome and inconsistent, resulting in large fluctuations in positioning accuracy. This makes it difficult to meet the requirements of high-precision roll production for positioning stability and adaptability, and restricts the improvement of subsequent processing quality. Therefore, a center drilling equipment for roll production is needed. Utility Model Content

The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0021] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0022] Please see Figure 1-5 This utility model provides a technical solution: a center drilling device for roll production, wherein: The device base 1 serves as the foundation of the equipment, with the top fixedly connected to the lower fixing component 2, baffle 3, and bracket 6, providing stable support for each component. It is made of high-strength cast iron to ensure the rigidity of the overall structure.

[0023] The lower fixing component 2 is fixedly connected to the baffle 3. The arc groove 4 on its surface is set opposite to the arc groove 4 of the upper fixing component 9, which can initially fit the shape of the roll. The baffle 3 provides auxiliary limiting from one side to prevent the roll from moving axially.

[0024] Hydraulic cylinders A7 and B8 are fixedly connected to the top of the bracket 6. The output end of hydraulic cylinder A7 is fixed to the upper fixed component 9, which can drive the upper fixed component 9 to move down and cooperate with the lower fixed component 2 to clamp the roller. The output end of hydraulic cylinder B8 is connected to the auxiliary fixed component 10, which pushes it to slide inside the upper fixed component 9.

[0025] The auxiliary fixing component 10 is slidably connected inside the upper fixing component 9, which can fill the gap between the upper fixing component 9 and the roll, increase the contact area, and, together with the multiple anti-slip strips 5 on the surface of the lower fixing component 2, increase the friction to prevent the roll from rotating relative to each other.

[0026] The bracket 6 is fixedly connected to the fixing plate 11, the fixing plate 11 is fixed to the motor 12, and the bottom is rotatably connected to the threaded rod 13. The threaded rod 13 is fixed to the output end of the motor 12. When the motor 12 starts, it can drive the threaded rod 13 to rotate.

[0027] The threaded rod 13 is threadedly sleeved with a slider 14 on its outer surface. The slider 14 is slidably connected to the bracket 6. When the threaded rod 13 rotates, the slider 14 slides along the bracket 6. The movable bracket 15 fixed on the surface of the slider 14 adjusts its position accordingly, thereby realizing the lateral adjustment of the drilling assembly 18.

[0028] The moving bracket 15 is slidably connected to the motor bracket 17, and an electric push rod 16 is fixed between the two. The extension and retraction of the electric push rod 16 can adjust the longitudinal position of the motor bracket 17, which facilitates precise adjustment of the longitudinal position of the drilling assembly 18.

[0029] The motor bracket 17 has a drilling assembly 18 fixed on its surface and a sensor 19 fixed on its bottom. The micro motor inside the drilling assembly 18 drives the conical drill bit to rotate and drill holes. The sensor 19 detects the position of the roller in real time to ensure that the drill hole is aligned with the axis.

[0030] The various structures work together to achieve stable fixing of the rolls and precise adjustment of the drilling position, improving drilling accuracy and efficiency, adapting to rolls of different specifications, and reducing the intensity of manual operation.

[0031] Working principle: When the center drilling equipment for roll production is working, the roll blank is first placed on the lower fixing component 2 at the top of the device base 1. The arc groove 4 on the surface of the lower fixing component 2 initially fits the shape of the roll. The baffle 3 provides auxiliary limiting from one side. Then, the hydraulic cylinder A7 at the top of the bracket 6 drives the upper fixing component 9 to move down, so that the arc groove 4 of the upper fixing component 9 cooperates with the lower fixing component 2 to clamp the roll. The hydraulic cylinder B8 simultaneously pushes the auxiliary fixing component 10 to slide inside the upper fixing component 9, filling the gap between the upper fixing component 9 and the roll, increasing the contact area, and the anti-slip strip 5 increases friction. To prevent relative rotation and further enhance the stability of the fixation, after the fixation is completed, the motor 12 on the fixing plate 11 starts, driving the threaded rod 13 to rotate, causing the threaded slider 14 to slide along the bracket 6. Then, the lateral position of the drilling assembly 18 is adjusted by the moving bracket 15. At the same time, the electric push rod 16 between the moving bracket 15 and the motor bracket 17 extends and retracts to adjust the longitudinal position of the motor bracket 17. The sensor 19 detects the position information of the roller in real time to ensure that the drilling assembly 18 is aligned with the axis. Finally, the micro motor inside the drilling assembly 18 drives the conical drill bit to rotate, completing the drilling operation of the center hole.

[0032] Example 1: Sensor 19 can be a laser displacement sensor, which is suitable for high-precision cold rolling roll production scenarios. In environments with high roll surface smoothness, the laser reflection signal is stable and can accurately measure the roll axis distance, ensuring that the positioning error of the drilling assembly 18 is less than 0.01mm. It has strong resistance to electromagnetic interference in the workshop and ensures measurement stability during continuous production.

[0033] Sensor 19 can be replaced with a vision sensor, which is suitable for scenarios with a lot of oxide scale on the surface of hot rolling roll blanks. It can ignore surface defects through image recognition, focus on the overall contour of the roll to locate the axis, and can simultaneously detect the roll length and diameter parameters, providing data support for subsequent drilling depth adjustment. It has comprehensive information acquisition and is adaptable to complex surface conditions.

[0034] Example 2: The arc groove 4 of the lower fixing component 2 can be adapted to the initial placement of rolls of different diameters. The anti-slip strip 5 on its surface increases friction to prevent rotation when clamped. When the roll is hoisted and lowered, the arc groove 4 can buffer the impact force to avoid equipment damage. The anti-slip strip 5 can also reduce the indentation on the roll surface and protect the blank precision. The baffle 3 not only restricts the lateral displacement of the rolls, but also serves as a uniform benchmark during mass production to ensure that each roll is placed in the same position. Its rigid connection with the lower fixed component 2 enhances the overall strength of the positioning mechanism and can withstand the lateral pressure of large rolls.

[0035] The bracket 6 provides a stable mounting platform for hydraulic cylinders A7 and B8, ensuring that the clamping force acts vertically on the roll. The slide rail on its side is precisely matched with the slider 14 to ensure the straightness of the lateral movement of the drilling assembly 18. The height design of the bracket 6 also provides sufficient operating space for the loading and unloading of the roll. The transmission cooperation between the threaded rod 13 and the motor 12 enables the stepless speed regulation movement of the drilling assembly 18. The self-locking characteristic of the thread ensures that the position does not shift during the drilling process. The length of the threaded rod 13 determines the maximum length of the rolls that the equipment can process, adapting to the needs of different specifications of products.

[0036] The extension and retraction stroke of the electric push rod 16 is precisely controllable, which can adjust the longitudinal feed of the drilling assembly 18 and quickly return to a safe position after drilling is completed. The thrust parameters of the electric push rod 16 are matched with the weight of the drilling assembly 18 to ensure smooth and wobbly movement.

[0037] Example 3: In the scenario of mass production of standardized rolls, the operator places roll blanks of the same specification on the lower fixed component 2 in sequence. The baffle 3 quickly aligns the ends of the rolls. The hydraulic cylinders A7 and B8 automatically complete the clamping according to the preset parameters. After the sensor 19 detects and confirms the position, the threaded rod 13 and the electric push rod 16 drive the drilling component 18 to be positioned according to the memory parameters, so as to achieve continuous and efficient drilling.

[0038] In the scenario of mass standardized roll production, after a set of drilling is completed, the equipment automatically resets, the conveyor belt removes the processed rolls, and the new blanks are sent to the lower fixed component 2 through the feeding mechanism. The shock absorption design of the device base 1 reduces the vibration impact of continuous operation and ensures product consistency.

[0039] In the production scenario of customized irregular rolls, the non-standard size roll blank is placed on the lower fixing component 2. The sensor 19 first scans the roll shape to establish a three-dimensional model. The system calculates the optimal drilling position. The hydraulic cylinder B8 drives the auxiliary fixing component 10 to adjust the extension and retraction according to the shape data to ensure a tight fit.

[0040] In the production scenario of customized irregular rolls, the sensor 19 monitors the roll position change in real time during the drilling process, the threaded rod 13 and the electric push rod 16 dynamically fine-tune to compensate for errors, the drilling assembly 18 automatically adjusts the speed according to the material parameters, and the heavy-duty design of the device base 1 provides stable support for the processing of irregular parts.

[0041] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
