Description

Technical Field

[0001] This utility model belongs to the field of steel pipe tooling technology, and in particular relates to a steel pipe cutting and positioning tooling. Background Technology

[0002] In the field of steel pipe processing, the precise cutting and positioning of steel pipes is undoubtedly a core part of the production process. This process relies heavily on efficient and flexible positioning fixtures, which must not only securely restrain and smoothly transport the steel pipes but also ensure their precise position during subsequent cutting operations. However, the core design of the widely used traditional steel pipe cutting and positioning fixtures often revolves around curved conveyor rollers. While this design can effectively handle the positioning and transport needs of round steel pipes, its inherent shape makes it difficult to process square steel pipes, thus exhibiting certain limitations in practical applications.

[0003] Faced with this challenge, traditional tooling proves inadequate when dealing with square steel pipes, often requiring companies to invest additional resources to redesign and customize entirely new positioning tooling to accommodate the processing needs of steel pipes of different shapes. This not only increases production costs but also extends production preparation time, impacting overall production efficiency and flexibility.

[0004] Therefore, it is essential to invent a steel pipe cutting and positioning fixture. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a steel pipe cutting and positioning fixture, including a fixture base, a drive shaft, a fixed sleeve, a drive component, a positioning arm, and a conveying roller. Two drive shafts are provided, and the fixed sleeves are fixedly installed at the same position on both drive shafts. Each fixed sleeve is fixedly connected to the lower end of the positioning arm, and the conveying roller is rotatably installed on the positioning arm. The two drive shafts are mirror-symmetrically installed inside the fixture base, and both ends protrude outside. One end is fixed to the output end of the drive component fixedly installed outside the fixture base.

[0006] Preferably, the other end of the drive shaft protruding outward is fixed to a gear disposed outside the tooling base, and the two gears mesh together.

[0007] Preferably, the positioning arm is a side-standing "V" shaped structure, with the upper part of the positioning arm protruding through a cross groove provided on the tooling base.

[0008] Preferably, the conveying roller rotatably mounted on the positioning arm is located above and outside the tooling base, and the upper halves of the two positioning arms form an inverted figure-eight structure.

[0009] Preferably, a conveyor wheel is provided below the two positioning arms, and the conveyor wheel is rotatably mounted on both sides of the cross groove.

[0010] Preferably, one of the conveyor wheels is fixed to the output end of a conveyor component that is fixedly installed outside the tooling base.

[0011] Preferably, there is a gap between the two conveying wheels, which does not affect the movement of the two positioning arms.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This invention features an innovative combination of a mirror-symmetrical dual-drive shaft and a fixed sleeve, supplemented by a side-standing "V"-shaped positioning arm, which together construct a unique inverted "V"-shaped structure. This design not only ensures the extreme stability of the steel pipe during positioning, effectively resisting the potential threats of offset and tilt, but also significantly improves the accuracy of the cutting position.

[0014] Of particular note is the unprecedented flexibility of the inverted figure-eight structural design. It not only perfectly adapts to the positioning requirements of round steel pipes, but also breaks through the shape limitations of traditional tooling, achieving compatibility with square steel pipes and even more shapes of steel pipes. This greatly expands the application range of this tooling and meets the needs of diversified production scenarios.

[0015] Furthermore, this invention incorporates an advanced mechanized drive and precision gear transmission system, achieving synchronous and precise control of the dual drive shafts. This not only simplifies manual operation and reduces reliance on operator skills, but also, through the intelligent collaboration of the built-in conveyor wheels and conveying components, automates the entire process of steel pipe conveying and cutting, significantly improving processing efficiency and capacity. Simultaneously, this design fully considers the positioning requirements of steel pipes of different sizes, ensuring the versatility and adaptability of the tooling in processing products of various specifications.

[0023] As attached Figure 1 To be continued Figure 3 As shown:

[0024] This utility model provides a steel pipe cutting and positioning fixture, including a fixture base 1, a drive shaft 2, a fixed sleeve 3, a drive component 4, a positioning arm 5, and a conveying roller 6. There are two drive shafts 2, and the fixed sleeve 3 is fixedly installed at the same position on both drive shafts 2. Each fixed sleeve 3 is fixedly connected to the lower end of the positioning arm 5, and the conveying roller 6 is rotatably installed on the positioning arm 5. The two drive shafts 2 are mirror-symmetrically rotatably installed in the fixture base 1, and both ends protrude outside. One end is fixed to the output end of the drive component 4 fixedly installed outside the fixture base 1.

[0025] Furthermore, the other end of the drive shaft 2 is cleverly connected to the gear 7 on the outside of the tooling base 1, and the two gears 7 mesh with each other to form a precision transmission system. This design ensures that when one drive shaft 2 is driven by power, the meshing of the gears 7 can synchronously drive the other drive shaft 2 to rotate, realizing the synchronization and precise control of the two shafts, and providing a solid foundation for the stable conveying and precise positioning of steel pipes.

[0026] Furthermore, the positioning arm 5 adopts a side-standing "V"-shaped structure. This innovative design not only enhances its structural strength but also gives it better adaptability and stability. The upper part of the positioning arm 5 cleverly passes through the cross groove 8 set on the tooling base 1 and extends to the outside of the base. This layout provides more flexible and precise space for the positioning of the steel pipe.

[0027] Furthermore, on the outer upper part of the tooling base 1, the upper halves of the two positioning arms 5 form a unique inverted figure-eight structure. Each positioning arm 5 is rotatably mounted with a conveying roller 6. This arrangement ensures the stability of the steel pipe during transport, while reducing the possibility of offset and tilting. The inverted figure-eight structure also allows the tooling to handle steel pipes of various shapes simultaneously, further enhancing its versatility and flexibility.

[0028] Furthermore, a conveyor wheel 9 is provided below the two positioning arms 5. The conveyor wheel 9 is rotatably mounted on both sides of the cross groove 8, providing additional support and guidance for the conveying process of the steel pipe. One of the conveyor wheels 9 is connected to the output end of the conveying component 10 fixedly mounted on the outside of the tooling base 1, ensuring that the conveyor wheel can move synchronously with the rotation of the conveying component, thereby driving the steel pipe forward.

[0029] Furthermore, the spacing between the two conveyor wheels 9 is carefully designed to ensure that they can work independently while avoiding mutual interference and collisions. At the same time, this spacing arrangement will not affect the normal movement of the two positioning arms 5, ensuring the smooth operation and efficient collaboration of the entire tooling system.

[0030] The working principle is as follows: When steel pipe cutting and positioning are required, the drive component 4, which is fixedly installed on the outside of the tooling base 1, is activated first. After the drive component 4 starts working, its output end is connected to one end of one of the drive shafts 2, providing power to the drive shaft 2. Since the other ends of the two drive shafts 2 are respectively fixed to gears 7 on the outside of the tooling base 1, and these two gears 7 mesh with each other, when one drive shaft 2 is driven by power, the meshing action of the gears 7 can synchronously drive the other drive shaft 2 to rotate. In this way, the two drive shafts 2 achieve synchronous opposite movements, enabling precise control and laying the foundation for subsequent steel pipe conveying and positioning.

[0031] Then, under the synchronous rotation of the drive shaft 2, the fixed sleeves 3 fixedly mounted on the drive shaft 2 also rotate. Since each fixed sleeve 3 is fixedly connected to the lower end of the positioning arm 5, the positioning arm 5 moves with the rotation of the fixed sleeve 3. The positioning arm 5 adopts a side-standing "V"-shaped structure, which not only enhances its structural strength but also allows the positioning arm 5 to remain stable during rotation. The upper part of the positioning arm 5 passes through the cross groove 8 on the tooling base 1, extends to the outside of the base, and forms an inverted "V"-shaped structure. This layout provides more flexible and precise space for the positioning of the steel pipe. When the steel pipe is placed between two positioning arms 5, due to the "V"-shaped structure and the inverted "V"-shaped layout of the positioning arms 5, the steel pipe can be stably clamped between the positioning arms 5. At this time, the conveying roller 6 rotatably mounted on the positioning arm 5 begins to function. The conveying roller 6 can roll along with the positioning arm 5, providing rolling support for the conveying process of the steel pipe, reducing the friction between the steel pipe and the tooling, and enabling the steel pipe to be conveyed forward smoothly.

[0032] Next, a conveyor wheel 9 is positioned below the two positioning arms 5. The conveyor wheel 9 is rotatably mounted on both sides of the cross groove 8, providing additional support and guidance for the conveying process of the steel pipe. One of the conveyor wheels 9 is connected to the output end of the conveying component 10 fixedly mounted externally to the tooling base 1, and can drive the conveyor wheel 9 to rotate when the conveying component 10 starts working. Due to the carefully designed spacing between the two conveyor wheels 9, they can work independently without interfering with or colliding with each other, nor affecting the normal movement of the positioning arms 5. In this way, the conveyor wheel 9 and the conveyor roller 6 work together to provide stable support and guidance for the conveying process of the steel pipe, ensuring that the steel pipe can be smoothly conveyed forward to the cutting position.

[0033] Finally, when the steel pipe is stably conveyed to the cutting position, the cutting device (although not specifically mentioned in the description of this utility model, it is usually set downstream of the tooling system) begins the cutting operation. Because the steel pipe has maintained a high degree of stability and precision during the conveying and positioning process, the cutting operation can be carried out smoothly, resulting in accurate cut length and cross-sectional quality.

[0034] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
