Description

Technical Field

[0001] This application relates to the field of stainless steel pipe processing, specifically a seamless stainless steel pipe positioning device. Background Technology

[0002] With the continuous development of industrial technology, seamless stainless steel pipes are increasingly widely used in many fields. Positioning devices play a crucial role in the production process of seamless stainless steel pipes. Precise positioning is especially essential when laser cutting large steel pipes. Traditionally, seamless stainless steel pipe positioning typically employs semi-mechanical positioning devices, which use mechanical structures to fix the steel pipe for positioning. However, when positioning large steel pipes, traditional methods have the following shortcomings: low positioning accuracy and a tendency to produce positioning errors. Utility Model Content

[0003] The purpose of this utility model is to provide a positioning device for laser cutting of seamless stainless steel tubes, so as to improve positioning accuracy, enhance adaptability, simplify operation, and improve stability. To achieve the above objectives, this application provides the following technical solution: a positioning device for seamless stainless steel tubes, comprising:

[0004] A trough, wherein the sidewall of the trough has an opening and the bottom has a slope;

[0005] A support column, wherein a slide rail and a rack are provided on the side wall of the support column, and both the slide rail and the rack are arranged vertically along the support column;

[0006] A transverse support frame, with its two ends respectively connected to the support column, and sliders provided at both ends of the transverse support frame, the sliders sliding along the slide rail;

[0007] The gear is disposed on the side wall of the transverse support frame and meshes with the rack. The gear is driven by a motor, and through meshing, the transverse support frame slides up and down along the slide rail.

[0008] A positioning platform is provided on the transverse support frame. The positioning platform is U-shaped and has a tracked conveyor structure on it. The tracked conveyor structure is driven to rotate by an engine provided on the positioning platform.

[0009] A positioning block is disposed on the track conveyor structure. The positioning block is V-shaped and is coaxially disposed with the track conveyor structure.

[0010] The motor ensures that the positioning platform is lower than the material trough, allowing the stainless steel pipe to enter the positioning platform.

[0011] In a preferred embodiment, this technical solution further includes a limiting strip, which is disposed on the side wall of the positioning platform.

[0012] In a preferred embodiment, the present technical solution further includes a guide rail and a sliding block. The guide rail is disposed on the top of the transverse support frame and the extension direction of the guide rail is perpendicular to the running direction of the track conveyor structure. The sliding block is disposed on the bottom of the positioning platform and slides along the guide rail.

[0013] In a preferred embodiment of this technical solution, multiple guide rails and sliding blocks are evenly arranged along the positioning platform, with each guide rail and sliding block corresponding to the other.

[0014] In a preferred embodiment, this technical solution further includes a fine-tuning structure, which is disposed on the track conveyor structure. The fine-tuning structure includes a U-shaped frame, rollers, and a turntable. The U-shaped frame is disposed on the track conveyor structure, the rollers' shafts are disposed on the U-shaped frame, and the rollers' shafts are connected to the turntable.

[0015] In a preferred embodiment of this technical solution, multiple rollers are provided, each roller has a groove, and a belt is fitted inside the groove to achieve linkage between the multiple rollers.

[0016] Compared with the prior art, the beneficial effects of this application are:

[0017] This invention employs a design with openings in the side walls of the material trough and a sloped bottom. This feature effectively utilizes the internal space of the trough, while the sloped design facilitates the natural introduction of stainless steel pipes. The slide rails and racks on the side walls of the support columns, along with the sliders at both ends of the transverse support frame, constitute a precise sliding mechanism. This mechanism allows the transverse support frame to slide up and down along the slide rails of the support columns, achieving high positioning accuracy and smooth movement. The meshing of the gears and racks on the side walls of the transverse support frame, driven by a motor, enables precise positioning of the transverse support frame. The crawler conveyor structure on the positioning platform, driven by an engine, further improves the transmission efficiency of the stainless steel pipes. The positioning block, with its V-shaped design and coaxial arrangement with the crawler conveyor structure, stably supports and positions the seamless stainless steel pipes, preventing swaying and positional shifts during transmission and ensuring accurate placement. The motor-controlled positioning platform is lower than the height of the material trough, allowing the seamless stainless steel pipes to smoothly enter the positioning platform. This design optimizes the pipe introduction process, reduces operational difficulty, and improves production safety. Attached Figure Description

[0025] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined or described in one figure, it will not need to be discussed or described in detail in the description of the subsequent figures.

[0026] In order to solve the technical problems in the background art, such as Figure 1-3 As shown, this application provides a technical solution: a seamless stainless steel tube positioning device, characterized as follows:

[0027] The material trough 1 is the main part of the device, used to store and guide seamless stainless steel tubes. The side walls of the material trough 1 are designed with openings to facilitate the discharge of the seamless stainless steel tubes. The bottom is sloped to allow the steel tubes to slide smoothly out of the material trough 1 under gravity. The size and shape of the material trough 1 are designed according to the length of the seamless stainless steel tubes to ensure stable storage and sliding. The support column 2 is a vertical structure that fixes and supports the entire device. Slide rails 3 and racks 4 are installed on its side walls, both arranged vertically along the support column 2. Slide rails 3 guide the sliding of the transverse support frame 5, while racks 4 mesh with gears 7 to achieve vertical movement of the transverse support frame 5. The two ends of the transverse support frame 5 are connected to the support column 2, and each end is equipped with a slider 6. The sliders 6 can slide freely on the slide rails 3, thereby achieving vertical movement of the transverse support frame 5. The transverse support frame 5 is designed with sufficient strength to support the weight of the positioning platform 9 and the crawler conveyor structure 10, while ensuring smooth movement driven by the motor 8. Gear 7 is mounted on the side wall of the transverse support frame 5 and meshes with rack 4. Motor 8 drives gear 7 to rotate, and through the meshing of gear 7 and rack 4, the transverse support frame 5 slides up and down along slide rail 3. Positioning platform 9, U-shaped, is mounted on the transverse support frame 5 and is used to fix and support the track conveyor structure 10. The track conveyor structure 10 is mounted on positioning platform 9 and is driven to rotate by an engine on positioning platform 9, used to convey seamless stainless steel pipes forward from the track conveyor structure 10 to a predetermined position. Positioning block 11, V-shaped, is mounted on the track conveyor structure 10 and is coaxially arranged with the track conveyor structure 10. The V-shaped structure has a centering function, and positioning block 11 is used to precisely position the seamless stainless steel pipe, ensuring the stability and accuracy of the steel pipe during the conveying process.

[0028] It should be noted that the limiting strip 12 is installed on the side wall of the positioning table 9. Its main function is to restrict the lateral movement of the seamless stainless steel pipe when it is conveyed onto the positioning table 9, ensuring the stability of the pipe during conveying and positioning. The limiting strip 12 can be designed as a detachable structure so that it can be retracted when not in use, reducing interference with the conveying structure 10.

[0029] Furthermore, guide rail 13 is positioned at the top of the transverse support frame 5, extending perpendicularly to the running direction of the track conveyor structure 10. The main function of guide rail 13 is to provide an additional movement path for positioning platform 9, allowing it to move on the transverse support frame 5 in a direction perpendicular to the track conveyor structure 10, i.e., horizontally. The design of guide rail 13 needs to ensure sufficient strength and rigidity to withstand the weight of positioning platform 9 and its load, while ensuring smooth and precise sliding. Sliding block 14 is positioned at the bottom of positioning platform 9 to cooperate with guide rail 13, enabling positioning platform 9 to slide along guide rail 13.

[0030] It should be noted that the guide rails 13 are evenly distributed along the length of the positioning platform 9 and are located on top of the transverse support frame 5. The extension direction of these guide rails 13 is perpendicular to the running direction of the track conveyor structure 10, providing smooth horizontal movement support for the positioning platform 9. The even distribution of the guide rails 13 ensures more stable and uniform movement of the positioning platform 9 on the transverse support frame 5, reducing wear or damage caused by uneven local stress. Corresponding to each guide rail 13, multiple sliding blocks 14 are evenly distributed on the bottom of the positioning platform 9. These sliding blocks 14 correspond one-to-one with the guide rails 13, ensuring the smoothness and accuracy of the positioning platform 9 when moving along the guide rails 13.

[0031] Furthermore, a fine-tuning structure 15 is mounted on the tracked conveyor structure 10 for fine-tuning the position of the seamless stainless steel pipe, ensuring the pipe's position is adjusted during the positioning process. The fine-tuning structure 15 includes a U-shaped frame 16, rollers 17, and a turntable 18. The U-shaped frame 16 is the main body of the fine-tuning structure 15, placed on the tracked conveyor structure 10, but not in direct contact with it. The design of the U-shaped frame 16 should ensure sufficient strength and stability to support the weight of the rollers 17 and the turntable 18, and guarantee the accuracy of the fine-tuning. The axle of the rollers 17 is mounted on the U-shaped frame 16, and the rollers 17 are in direct contact with the tracked conveyor structure 10. The rollers 17 roll forward, driving the U-shaped frame 16 forward, which pushes the steel pipe during the fine-tuning process to achieve position adjustment. The turntable 18 is connected to the axle of the rollers 17; the rotation of the turntable 18 drives the rollers 17, achieving fine-tuning of the steel pipe's position. The turntable 18 can be designed for manual or automatic control to adapt to different operational needs.

[0032] It should be noted that multiple rollers 17 are evenly distributed on the U-shaped frame 16 to ensure the stability and uniform force distribution during the operation of the U-shaped frame 16. Each roller 17 is designed with a groove 19, and a belt 20 is fitted inside these grooves 19 to achieve linkage between multiple rollers 17. The groove 19 is a design feature on the roller 17, used to accommodate the belt 20. This design allows multiple rollers 17 to be connected by the belt 20 to achieve synchronous rotation. The belt 20 can be made of rubber, polyurethane, or other suitable materials to ensure sufficient friction while reducing wear when the rollers 17 rotate. Through the connection of the belts 20, when one roller 17 rotates, the other rollers 17 will also rotate, achieving a linkage effect. This linkage mechanism ensures smooth movement and precise positioning of the U-shaped frame 16. The linkage mechanism also reduces the complexity of individually controlling each roller 17 and simplifies the design of the control system.

[0033] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
