Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, and in particular to a fixture for producing and processing risers. Background Technology

[0002] The background technology of riser production and processing fixtures mainly involves the technical requirements for effectively clamping and cutting risers in casting, metal processing and precision manufacturing processes. In traditional processing, risers usually lead to waste and inaccurate processing, causing unnecessary trouble and costs to the production process. In order to solve this problem, many manufacturing companies need a high-efficiency, accurate fixture equipment that can improve production efficiency.

[0003] Traditional riser production and processing fixtures consist of a base, clamping parts, positioning devices, cutting devices, and adjustment devices. Their working principle is to fix the workpiece by clamping force (mechanical, hydraulic, or pneumatic) and to ensure that the workpiece does not shift during processing by positioning. The fixture maintains the stability of the workpiece during processing to ensure high-precision processing, and releases the workpiece after completion.

[0004] Traditional fixtures often rely on manual adjustment of clamping force and fixture position. However, manual operation is prone to errors and the adjustment process is cumbersome. This inflexible adjustment method makes it impossible to guarantee consistent clamping effect. In particular, when dealing with risers of different shapes or sizes, problems such as insufficient clamping and excessive clamping may occur. Therefore, a fixture for riser production and processing is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a fixture for riser production and processing, aiming to improve the problem of unstable clamping effect of existing fixtures for riser production and processing.

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 , Figure 2 and Figure 4This utility model provides an embodiment of a fixture for producing risers, comprising a fixed frame 2, a hydraulic telescopic device 3 fixedly connected to the top of the fixed frame 2, and a sliding plate 4 fixedly connected to the drive end of the hydraulic telescopic device 3. The hydraulic telescopic device 3 provides the power source and adjustment function of the fixture. The hydraulic telescopic device 3 can control the movement of the sliding plate 4 within a specific range by adjusting the telescopic length, thereby achieving precise adjustment of the fixture components. A sliding block 5 is fixedly connected to one side of the sliding plate 4. A fixed plate 7 is provided on the inner wall of the fixed frame 2. The fixed plate 7 plays a role in fixing and supporting, enhancing the stability of the entire structure. A vertical guide rail 6 is provided on one side of the fixed plate 7. The guide rail 6 provides a smooth sliding path, ensuring that the sliding block 5 is stable and does not deviate from the trajectory during the sliding process.

[0033] The inner wall of the sliding block 5 is slidably connected to the outer wall of the guide rail 6. Each end of the sliding plate 4 is hinged with a bent rod 8, which can rotate on the sliding plate 4, bringing greater flexibility. One end of each of the two bent rods 8 is fixedly connected to a connecting block 10, and one end of the connecting block 10 is fixedly connected to a gripper 11. The gripper 11 is used to directly clamp the material. Through the synergistic action of the hydraulic telescopic device 3 and the bent rod 8, the gripper 11 can stably and accurately clamp and position the riser in the process, ensuring the smooth progress of cutting and processing. One side of the bent rod 8 is fixedly connected to a rotating rod 9, which allows the bent rod 8 to rotate at a certain angle. One end of the rotating rod 9 is slidably connected to a groove on one side of the fixed plate 7, so that the two bent rods 8 can be clamped inward. The inner wall of the fixed frame 2 is provided with a cutting assembly.

[0034] Reference Figures 1 to 3 The cutting assembly includes a second guide rail 12, which provides support and guidance to ensure that the cutting assembly moves smoothly along a predetermined trajectory during operation. Limiting plates 14 are fixedly connected to both ends of the second guide rail 12, limiting its range of motion and preventing the component from exceeding its range, thus ensuring the accuracy and stability of the cutting operation. A second sliding block 13 is slidably connected to the outer wall of the second guide rail 12, ensuring smooth movement of the cutting assembly. A fixing block 20 is fixedly connected to one side of the second sliding block 13. Two rotating plates 15 are rotatably connected to the inner wall of the fixing block 20, allowing the rotating plates 15 to rotate around the fixing block 20, providing the necessary rotational flexibility.

[0035] One end of each of the two rotating plates 15 is rotatably connected to a connecting rod 16. A fixed housing 17 is fixedly connected to one side of the connecting rod 16. A motor 18 is fixedly connected to the inner wall of the fixed housing 17. The fixed housing 17 serves to protect and support the motor 18, ensuring stable operation of the motor 18. A cutter 19 is fixedly connected to the drive end of the motor 18. The cutter 19 is responsible for performing the actual cutting task by rotating and cutting. A base 1 is fixedly connected to the bottom of the fixed frame 2. The base 1 provides a stable support platform for the entire device, ensuring stability and safety during operation.

[0036] Working principle: By activating the hydraulic expansion joint 3, the drive end of the hydraulic expansion joint 3 can drive the sliding plate 4 to move. The sliding plate 4 can slide on the guide rail 6 through the sliding block 5. The movement of the sliding plate 4 can drive the bent rod 8 to rotate. The rotation of the bent rod 8 can drive the connecting block 10 and the gripper 11 to move, thereby achieving the clamping and fixing effect on the riser. The sliding block 5 and the guide rail 6 can improve the stability of the equipment during operation and avoid shaking, which would affect the clamping effect of the equipment.

[0037] By moving the sliding block 13, the sliding block 13 can slide on the guide rail 12 to adjust its position. The movement of the sliding block 13 can drive the fixed block 20 to move, and the rotating plate 15 can rotate on the fixed block 20. The rotation of the rotating plate 15 can drive the connecting rod 16 to move, thereby adjusting the cutting device to a suitable position for operation. The guide rail 12 and the sliding block 13 can make the cutting device move along the set trajectory and adjust to a suitable cutting position, ensuring the precise positioning of the cutting device. Moreover, through the cooperation of the guide rail 12 and the sliding block 13, fine size adjustment can be achieved, ensuring the accuracy and efficiency of the cutting operation, meeting the cutting needs of workpieces of different sizes, thereby improving work efficiency and reducing errors.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
