Description

Technical Field

[0001] This utility model relates to the field of machining fixture technology, and in particular to a fixture for machining copper tubes for crystallizers. Background Technology

[0002] In modern continuous casting of steel, the crystallizer, as the core component of the continuous casting process, directly affects the quality of the cast billet and production efficiency. Crystallizers are typically cylindrical or arc-shaped, and during processing, they need to be securely fixed to the machine tool using fixtures to ensure precise milling, drilling, and other machining operations. However, existing crystallizer machining fixtures have many drawbacks, severely restricting the machining quality and production efficiency of the crystallizer.

[0003] First, existing fixtures have poor adaptability. Traditional crystallizer processing fixtures are mostly designed with fixed dimensions, only suitable for crystallizers of a specific diameter. In actual production, different specifications of continuous casting require crystallizers of different diameters, necessitating frequent fixture changes when processing different sizes of crystallizers. This not only increases production costs but also leads to low production efficiency.

[0004] Secondly, the positioning stability of existing fixtures is insufficient. Current fixtures often rely solely on radial clamping force to hold the crystallizer in place. However, in actual machining processes, especially during milling, drilling, and other operations with significant impact, the crystallizer is prone to axial displacement. This axial displacement leads to increased machining errors and severely affects product quality.

[0005] In summary, existing crystallizer processing fixtures have significant shortcomings in terms of adaptability and positioning stability, failing to meet the precision and efficiency requirements of modern continuous casting production. Therefore, developing a widely adaptable and stable crystallizer processing fixture is of significant practical importance, as it will help improve the processing quality of crystallizers, reduce production costs, and enhance the overall efficiency of continuous casting production. Utility Model Content

[0006] To overcome existing problems, embodiments of this application provide a jig for processing copper tubes of crystallizers, which is adaptable and has stable positioning to meet the processing needs of crystallizers of different diameters and improve processing accuracy and production efficiency.

[0007] The technical solution adopted by the embodiments of this application to solve its technical problem is: A clamp for processing copper tubes in a crystallizer includes a base, and an axial clamping assembly and a vertical clamping assembly disposed above the base. The axial clamping assembly is connected to the base by high-strength bolts and locating pins, and the connection part is provided with ribs. The bottom of the support of the axial clamping assembly contacts the upper surface of the base, and the support is firmly fixed to the base by welding. In order to enhance the strength of the connection part, ribs are added at the connection part between the support and the base. The ribs adopt a triangular structure. One end of the axial clamping assembly is provided with a cylinder body, and the output end of the cylinder body is detachably installed with the first clamping block. The axial clamping assembly includes a support, and both ends of the inner wall of the support are provided with sliders. The first clamping block is slidably connected to the sliders. The support has a first clamping block and a second clamping block respectively. The opposing surfaces of the first clamping block and the second clamping block are arc-shaped surfaces adapted to the shape of the outer wall of the crystallizer copper tube, and have a concave buffer pad. The second clamping block is fixedly connected to the support, and the first clamping block and the support have a slidable structure. When processing crystallizer copper tubes of different diameters, the crystallizer copper tube is placed between the first clamping block and the second clamping block. Based on the diameter of the crystallizer copper tube, the cylinder body is activated. By controlling the piston rod of the cylinder body to extend or retract, the first clamping block slides within the support. For crystallizer copper tubes with smaller diameters, the piston rod of the cylinder body is retracted, causing the first clamping block to move closer to the second clamping block. For crystallizer copper tubes with larger diameters, the piston rod is extended, causing the first clamping block to move away from the second clamping block. During the adjustment process, the distance between the first and second clamping blocks is monitored in real time using measuring tools to ensure that it matches the diameter of the crystallizer copper tube. When the first and second clamping blocks are tightly fitted against the outer wall of the crystallizer copper tube, the cylinder body is stopped, completing the initial axial fixation of the crystallizer copper tube. Preferably, there are two vertical clamping components, which are respectively disposed at both ends of the axial clamping component. After the axial clamping component fixes the workpiece, the two vertical clamping components fix the workpiece in the vertical direction. Through the joint clamping in the axial and vertical directions, the crystallizer can be tightly fixed.

[0008] Preferably, the vertical clamping assembly includes a fixed frame, a screw, and a holding rod. The outer wall of the holding rod is provided with anti-slip texture. The screw is fixedly connected to the holding rod, and the cross-sectional diameter of the screw is smaller than that of the holding rod. The bottom end of the screw is provided with a rubber pad, which can reduce the pressure friction. The screw is screwed into the threaded hole of the fixed frame. One end of the screw is connected to the holding rod, and the other end is an arc shape adapted to the outer wall of the copper tube of the crystallizer. The fixed frame of the vertical clamping assembly is connected to the base by bolts. The connection part is provided with reinforcing ribs. Bolt holes are machined at corresponding positions on the fixed frame and the base of the vertical clamping assembly. The fixed frame is placed in the designated position, and the fixed frame is fastened to the base by bolts. Reinforcing ribs are added to the connection part to improve the fatigue resistance of the connection part. The shape of the reinforcing ribs is designed according to the structure of the fixed frame and the base.

[0009] The advantages of the embodiments of this application are: An axial clamping assembly is provided, with one end connected to the cylinder body and containing a support. The support contains a first clamping block and a second clamping block. The second clamping block is fixedly connected to the support, while the first clamping block and the support are slidable. Power is provided by the cylinder body, which can push the first clamping block to slide within the support, thereby changing the distance between the first and second clamping blocks. By adjusting the position of the first clamping block, the two clamping blocks are made to fit tightly against the outer wall of the crystallizer copper tube, realizing the clamping and fixing of crystallizer copper tubes of different diameters, which greatly improves the adaptability of the fixture.

[0010] Two vertical clamping components are respectively set at both ends of the axial clamping component. After the axial clamping component completes the initial fixation of the crystallizer copper tube, the two vertical clamping components start to work to further fix the workpiece in the vertical direction. The vertical clamping component includes a fixing frame, a screw and a holding rod. By rotating the holding rod, the screw can be pushed closer to the crystallizer copper tube until the screw is tightly pressed against the outer wall of the crystallizer copper tube, applying additional clamping force in the vertical direction, effectively preventing the crystallizer copper tube from shifting along the axial direction during processing, and enhancing the positioning stability of the fixture.

[0014] This application provides a fixture for processing copper tubes in a crystallizer, solving the problems in the prior art. Two vertical clamping components are respectively set at both ends of the axial clamping component. After the axial clamping component completes the initial fixation of the copper tube in the crystallizer, the two vertical clamping components start to work, further fixing the workpiece in the vertical direction. The vertical clamping component includes a fixing frame, a screw, and a holding rod. By rotating the holding rod, the screw can be pushed closer to the copper tube in the crystallizer until the screw is tightly pressed against the outer wall of the copper tube in the crystallizer, applying additional clamping force in the vertical direction, effectively preventing the copper tube in the crystallizer from shifting along the axial direction during processing, and enhancing the positioning stability of the fixture.

[0015] The technical solution in this application is to solve the above problems, and the overall approach is as follows: Example This embodiment provides the specific structure of the fixture for machining copper tubes in a crystallizer, such as... Figure 1-3 As shown, it includes a base 2, and an axial clamping assembly 3 and a vertical clamping assembly 4 disposed above the base 2. The axial clamping assembly 3 is connected to the base 2 by high-strength bolts and positioning pins, and the connection part is provided with ribs. The bottom of the support 31 of the axial clamping assembly 3 contacts the upper surface of the base 2, and the support 31 is firmly fixed to the base 2 by welding. In order to enhance the strength of the connection part, ribs are added at the connection part between the support 31 and the base 2. The ribs adopt a triangular structure. One end of the axial clamping assembly 3 is provided with a cylinder body 1. The output end of the cylinder body 1 is detachably installed with the first clamping block 32. The axial clamping assembly 3 includes a support 31. Both ends of the inner wall of the support 31 are provided with sliders 34. The first clamping block 32 and the sliders 34 are slidably connected. The support 31 is provided with a first clamping block 32 and a second clamping block 33. The surfaces of the first clamping block 32 and the second clamping block 33 facing each other are arc-shaped surfaces that are adapted to the shape of the outer wall of the copper tube of the crystallizer, and a buffer pad is recessed inside. The second clamping block 33 is fixedly connected to the support 31, and the first clamping block 32 and the support 31 are slidable. Furthermore, when processing crystallizer copper tubes of different diameters, the crystallizer copper tube is placed between the first clamping block 32 and the second clamping block 33. Depending on the diameter of the crystallizer copper tube, the cylinder body 1 is activated. By controlling the piston rod of the cylinder body 1 to extend or retract, the first clamping block 32 is slid within the support 31. For crystallizer copper tubes with smaller diameters, the piston rod of the cylinder body 1 is retracted, causing the first clamping block 32 to move closer to the second clamping block 33. For crystallizer copper tubes with larger diameters, the piston rod is extended, causing the first clamping block 32 to move away from the second clamping block 33. During the adjustment process, the distance between the first clamping block 32 and the second clamping block 33 is monitored in real time using measuring tools to ensure that it matches the diameter of the crystallizer copper tube. When the first clamping block 32 and the second clamping block 33 are tightly attached to the outer wall of the crystallizer copper tube, the cylinder body 1 is stopped, completing the initial axial fixation of the crystallizer copper tube.

[0016] There are two vertical clamping components 4, which are respectively set at both ends of the axial clamping component 3. After the axial clamping component 3 fixes the workpiece, the two vertical clamping components 4 fix the workpiece in the vertical direction.

[0017] The vertical clamping assembly 4 includes a fixed frame 41, a screw 42, and a holding rod 43. The outer wall of the holding rod 43 is provided with anti-slip texture. The screw 42 is fixedly connected to the holding rod 43, and the cross-sectional diameter of the screw 42 is smaller than that of the holding rod 43. The bottom end of the screw 42 is provided with a rubber pad, which can reduce the squeezing friction. The screw 42 is screwed into the threaded hole of the fixed frame 41. One end of the screw 42 is connected to the holding rod 43, and the other end is an arc shape adapted to the outer wall of the copper tube of the crystallizer. The fixed frame 41 of the vertical clamping assembly 4 is connected to the base 2 by bolts. The connection part is provided with reinforcing ribs. Bolt holes are machined at corresponding positions of the fixed frame 41 and the base 2 of the vertical clamping assembly 4. The fixed frame 41 is placed in the designated position, and the fixed frame 41 is fastened to the base 2 by bolts. Reinforcing ribs are added to the connection part to improve the fatigue resistance of the connection part. The shape of the reinforcing ribs is designed according to the structure of the fixed frame 41 and the base 2.

[0018] Furthermore, the fixing bracket 41 is fixed to the corresponding positions at both ends of the axial clamping assembly 3 with bolts. Then, the screw 42 is screwed into the threaded hole on the fixing bracket 41 to ensure that the screw 42 can rotate smoothly. After installation, the holding rod 43 is rotated to drive the screw 42 to rotate, so that the screw 42 moves closer to the crystallizer copper tube. During the rotation, the contact between the screw 42 and the crystallizer copper tube is closely observed to ensure that the arc-shaped end of the screw 42 can accurately abut against the outer wall of the crystallizer copper tube. After the vertical clamping is completed, the fixing of the crystallizer copper tube is checked again to ensure that it is stably positioned in the vertical direction.

[0019] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. 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. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
