Description

Technical Field

[0001] This utility model relates to the field of laser tube cutting machine technology, and in particular to a guide clamping device for a laser tube cutting machine. Background Technology

[0002] With the continuous development and application of laser cutting technology, laser tube cutting machines have become an important automated processing equipment in modern manufacturing, widely used in the cutting, processing, and precision manufacturing of metal tubes. Laser tube cutting machines are typically used for the precision cutting of various metal tubes and irregularly shaped tubes. They achieve efficient and precise cutting by locally heating and melting the material using a high-power laser beam. However, in actual cutting, the fixing, guiding, and clamping of the tube are crucial factors in ensuring cutting quality and accuracy. During the cutting process, the tube often experiences localized expansion or vibration due to the heat generated by laser cutting. This is especially true when cutting long or thin tubes, where deformation or displacement can lead to a decrease in cutting accuracy. Therefore, for industries requiring high-precision cutting, developing efficient and stable guiding and clamping devices is particularly important to address common issues such as tube vibration, positional deviation, and cutting errors encountered during laser tube cutting. Utility Model Content

[0003] The purpose of this invention is to provide a stable and adjustable clamping force through the linkage of a telescopic cylinder and a rotating motor, ensuring that the pipe remains firmly in place during the cutting process. This solves the problem of decreased cutting accuracy caused by unstable clamping, prevents the pipe from sliding or vibrating during cutting, and ensures high-quality cutting results. The clamping blocks made of rubber have good friction, cushioning performance, and adaptability, reducing the risk of damage to the surface of the clamped object. This minimizes the impact on the pipe surface during clamping.

[0004] This utility model achieves the above-mentioned objectives through the following technical solution: a guide clamping device for a laser tube cutting machine, including a support base, a clamping device at the upper end of the support base, a fixing block on one side of the upper end of the support base, a fixing support member fixedly connected to one side of the fixing block, and a circular tube between the clamping device and the fixing support member; the clamping device includes a telescopic cylinder, a U-shaped fixing block fixedly connected to the output end of the telescopic cylinder, a rotating motor between the U-shaped fixing blocks, speed limiting wheels on both sides of the rotating motor, a rotating bearing fixedly connected to one side of the rotating motor and the U-shaped fixing block, guide wheels on both sides of the rotating bearing, and first circular clamping blocks at the upper and lower ends of both sides of the output end of the U-shaped fixing block; the clamping device provides sufficient power through the telescopic cylinder and the rotating motor to ensure stability when clamping objects during operation; the guide wheels and rotating bearings further ensure the accuracy and stability of the clamping action, avoiding any slippage or offset; the entire structure is compact and stable; the support base, clamping device, fixing block, and other components work together to provide efficient and precise clamping and fixing functions.

[0005] Furthermore, the fixed support includes two T-shaped fixing blocks. A contour block is fixedly connected to one end of each T-shaped fixing block, and a second circular clamping block is fixedly connected to the top and bottom of each contour block. The circular design of the clamping blocks allows them to provide a more uniform clamping force when in contact with surfaces of objects of different shapes. In particular, the second circular clamping blocks are located at the top and bottom ends of the contour blocks, making the distribution of clamping force more uniform and avoiding damage or instability caused by concentrated pressure.

[0006] Furthermore, both the first and second circular clamping blocks are made of rubber. The rubber material provides stronger friction, cushioning performance, and adaptability, reducing damage to the object surface, improving clamping stability, extending the service life of the clamping blocks, reducing noise, and improving operational comfort and safety.

[0007] Furthermore, the speed limiting wheel and the guide wheel are in contact to control the speed of the guide wheel. Through friction, the speed of the guide wheel can be limited to avoid excessively fast clamping, which could damage the surface of the pipe.

[0008] Furthermore, the telescopic cylinder is fixedly connected to the support base.

[0009] Beneficial effects: This utility model is reasonably designed and has the following beneficial effects:

[0010] 1. The linkage between the telescopic cylinder and the rotary motor provides a stable and adjustable clamping force, ensuring the pipe remains firmly in place during cutting. This solves the problem of decreased cutting accuracy caused by unstable clamping, prevents the pipe from sliding or vibrating during cutting, and ensures high-quality cutting results.

[0011] 2. The design using first and second circular clamping blocks not only accommodates objects of different shapes, but also provides a uniform contact surface through the rubber material, resulting in a more even distribution of clamping force and preventing damage to the object caused by concentrated pressure. This solves the problem of uneven clamping force distribution in traditional fixing methods, which may lead to workpiece damage or instability.

[0012] 3. The clamping blocks in this design utilize rubber materials, which offer excellent friction, cushioning, and adaptability, reducing the risk of damage to the surface of the clamped object. This minimizes the impact on the pipe surface during clamping, improving operational safety and comfort. The design of the speed-limiting wheel and guide wheel effectively controls the clamping speed, preventing damage to the pipe surface caused by excessive clamping speed. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Combination Figures 1 to 3As shown, a laser tube cutting machine guide clamping device includes a support base 1, a clamping device 2 is provided on the upper end of the support base 1, a fixing block 3 is provided on one side of the upper end of the support base 1, a fixing support member 4 is fixedly connected to one side of the fixing block 3, and a round tube 5 is provided between the clamping device 2 and the fixing support member 4. The clamping device 2 includes a telescopic cylinder 21, with a U-shaped fixing block 22 fixedly connected to the output end of the telescopic cylinder 21. A rotating motor 23 is arranged between the U-shaped fixing blocks 22. Speed ​​limiting wheels 24 are arranged on both sides of the rotating motor 23. A rotating bearing 25 is fixedly connected to one side of the rotating motor 23 and the U-shaped fixing block 22. Guide wheels 26 are arranged on both sides of the rotating bearing 25. First circular clamping blocks 27 are arranged at the upper and lower ends of both sides of the output end of the U-shaped fixing block 22. The clamping device provides sufficient power through the telescopic cylinder and the rotating motor to ensure the stability of clamping objects during operation. The guide wheels and rotating bearings further ensure the accuracy and stability of the clamping action and prevent any slippage or deviation. The entire structure is compact and stable. The support base, clamping device, fixing blocks and other components work together to provide efficient and precise clamping and fixing functions.

[0019] The fixed support 4 includes two T-shaped fixing blocks 41. A contour block 42 is fixedly connected to one end of each T-shaped fixing block 41. A second circular clamping block 43 is fixedly connected to both ends of the contour block 42. The circular design of the clamping blocks allows them to provide a more uniform clamping force when in contact with surfaces of objects of different shapes. In particular, the second circular clamping blocks are located at the upper and lower ends of the contour blocks, making the distribution of clamping force more uniform and avoiding damage or instability caused by concentrated pressure. Both the first circular clamping block 27 and the second circular clamping block 43 are made of rubber. The rubber material provides stronger friction, cushioning performance, and adaptability, reducing damage to the object surface, improving clamping stability, extending the service life of the clamping blocks, reducing noise, and improving the comfort and safety of operation. The speed limiting wheel 24 is in contact with the guide wheel 26 and is used to control the speed of the guide wheel 26. Through friction, the speed of the guide wheel can be limited accordingly to avoid excessively fast clamping, which could damage the surface of the pipe. The telescopic cylinder 21 is fixedly connected to the support base 1.

[0020] Working principle: When the laser tube cutting machine is working, the telescopic cylinder 21 is activated. The output end of the cylinder pushes the U-shaped fixing block 22 towards the tube. The telescopic cylinder provides linear power, enabling the clamping device to quickly and stably contact and clamp the tube in a short time, ensuring its stability throughout the cutting process. The U-shaped fixing block 22, in cooperation with the rotating motor 23, achieves the clamping action on the tube. The rotating motor 23 drives the U-shaped fixing block to rotate, and the rotating bearing 25 drives the guide wheel 26. At the same time, the speed limiting wheel 24 limits the rotation speed of the guide wheel 26, thereby controlling the clamping speed and force to avoid damage to the tube surface due to excessive clamping.
