Description

Technical Field

[0001] This utility model relates to the field of radiometric measuring instruments, and in particular to a pipe positioning component for a pipe cutting machine. Background Technology

[0002] In pipe processing, pipe cutting machines are commonly used equipment, primarily for cutting pipes to a fixed length. The pipe positioning assembly, a crucial component of the pipe cutting machine, directly impacts the cutting quality due to its positioning accuracy and stability. Existing pipe cutting machine positioning assemblies are cumbersome to adjust when positioning pipes of different sizes, often requiring replacement of guide support components of varying specifications. This complex and time-consuming operation reduces processing efficiency. Furthermore, some positioning assemblies do not clamp the pipe securely enough, leading to pipe wobbling during cutting, resulting in decreased cutting accuracy and defective products. Therefore, we propose a new pipe cutting machine positioning assembly. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a pipe fitting positioning component for a pipe cutting machine. This utility model solves the problem that existing pipe fitting positioning components for pipe cutting machines are cumbersome to adjust when positioning pipe fittings of different sizes, often requiring the replacement of guide support components of different specifications. This process is complex and time-consuming, reducing processing efficiency. Furthermore, some positioning components do not clamp the pipe fitting securely enough, leading to pipe shaking during cutting, resulting in decreased cutting accuracy and the production of defective products.

[0004] This utility model discloses a pipe cutting machine fitting positioning assembly, including a support frame. A motor is fixedly installed on one side of the upper part of the support frame. The rotating shaft of the motor passes through the support frame and is fixedly connected to a four-jaw chuck. The clamps on the four-jaw chuck are fixedly connected to the clamping plate. Multiple mounting brackets are provided at equal intervals at the lower end of the support frame. The mounting brackets are movably connected to the connecting plate through a first shaft. Fixed plates are provided at both ends of one side of the mounting bracket. The fixed plates are movably connected to the hydraulic cylinder through pins. A through groove is opened on the mounting bracket above the hydraulic cylinder. The stroke end of the hydraulic cylinder passes through the through groove and is movably connected to a second shaft. Both ends of the second shaft are movably connected to the connecting plate. Guide rollers are provided at the upper ends of the two connecting plates. A variable diameter arc groove is opened in the middle of the guide rollers.

[0005] In the above scheme, the connecting plate and the guide roller are movably connected by a screw.

[0006] In the above scheme, a protective groove is provided on the outside of the motor.

[0007] In the above scheme, the inner side of the clamp is provided with anti-slip texture.

[0008] In the above scheme, multiple support legs are arranged at equal intervals below the support frame.

[0009] The advantages and beneficial effects of this utility model are as follows: This utility model provides a pipe cutting machine pipe positioning component. The second shaft is driven by a hydraulic cylinder, which drives the connecting plate to rotate around the first shaft, thereby realizing the up and down movement of the guide roller. Combined with the variable diameter arc groove in the middle of the guide roller, it can quickly adapt to pipes of different sizes without replacing the guide support components, effectively improving processing efficiency. The inner side of the clamping plate on the four-jaw chuck is provided with anti-slip texture, which can increase the friction between the clamping plate and the pipe, making the pipe clamped more firmly and less prone to shaking during the cutting process, ensuring cutting accuracy and reducing the production of defective products.

[0016] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0017] like Figure 1-4As shown, this utility model is a pipe positioning component for a pipe cutting machine, including a support frame 1. A motor 2 is fixedly installed on one side of the upper part of the support frame 1. The rotating shaft of the motor 2 passes through the support frame 1 and is fixedly connected to a four-jaw chuck 3. The motor 2 serves as a power source, and its rotating shaft passes through the support frame 1 and is fixedly connected to the four-jaw chuck 3, enabling the four-jaw chuck 3 to drive the pipe to rotate synchronously, providing stable rotational power for the cutting operation. The clamps on the four-jaw chuck 3 are fixedly connected to the clamping plates 4. The four clamping plates 4 are perpendicular to each other. The four-jaw chuck 3 can clamp and fix pipes of different sizes by moving the clamps radially through the clamps. The lower end of the support frame 1 is provided with multiple equally spaced mounting brackets 5. The mounting brackets 5 are connected to the connecting plate through a first shaft 6. 7. Movable connection: The mounting frame 5 has fixed plates 9 at both ends on one side. The fixed plates 9 are movably connected to the hydraulic cylinder 10 via pins. The mounting frame 5 has a through groove 11 above the hydraulic cylinder 10. The stroke end of the hydraulic cylinder 10 passes through the through groove 11 and is movably connected to the second shaft 8. Both ends of the second shaft 8 are movably connected to the connecting plate 7. During extension and retraction, the hydraulic cylinder 10 can rotate around the pin. The extension and retraction of the hydraulic cylinder 10 drives the second shaft 8 to transmit power, causing the connecting plate 7 to rotate around the first shaft 6. When the connecting plate 7 rotates, the height of the guide roller 12 can be adjusted. The variable diameter arc groove 13 adapts to pipes of different sizes, allowing the pipes to stably fit on the guide roller 12, improving support stability.

[0018] The two connecting plates 7 are provided with guide rollers 12 at their upper ends, and the guide rollers 12 are provided with a variable diameter arc groove 13 in the middle.

[0019] The connecting plate 7 and the guide roller 12 are movably connected by a screw. Nuts are provided at both ends of the screw. The guide roller 12 can be positioned by the bolts and nuts, so that the guide roller 12 can support pipes of different sizes through the variable diameter arc groove 13.

[0020] The motor 2 is provided with a protective groove 14 on its outer side. The protective groove 14 can form a protective barrier around the motor 2, effectively blocking metal chips, dust and coolant and other impurities generated during the cutting process from entering the motor 2. This prevents impurities from causing wear or short circuits to the core components of the motor 2, such as windings and bearings, thereby extending the service life of the motor 2 and reducing the equipment failure rate.

[0021] The inner side of the clamping plate 4 is provided with anti-slip texture 15. The anti-slip texture 15 can increase the static friction between the clamping plate 4 and the outer surface of the pipe. When the clamping plate 4 clamps the pipe, it can effectively prevent the pipe from sliding or moving axially during the rotary cutting process, ensuring that the pipe always maintains a stable positioning state, thereby improving the flatness of the cutting section and the cutting accuracy.

[0022] The support frame 1 is provided with multiple equally spaced support legs 16 below it.

[0023] Specifically, in this invention, based on the dimensions of the pipe fitting, the hydraulic cylinder 10 is activated. The stroke end of the hydraulic cylinder 10 drives the second shaft 8 to move within the through groove 11, thereby causing the connecting plate 7 to rotate around the first shaft 6. The height of the guide roller 12 is adjusted so that the pipe fitting can be placed within the variable diameter arc groove 13 of the guide roller 12. Then, one end of the pipe fitting is placed in the four-jaw chuck 3. The clamps of the four-jaw chuck 3 drive the clamping plate 4 to clamp and fix the pipe fitting. The anti-slip texture 15 ensures a firm clamping. The motor 2 is activated, and the motor 2 drives the four-jaw chuck 3 and the pipe fitting to rotate, cooperating with the pipe cutter to perform the cutting operation.

[0024] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
