Description

Technical Field

[0001] This utility model belongs to the field of laser cutting equipment technology, specifically relating to a laser tube cutting chuck. Background Technology

[0002] In laser tube cutting, impurities such as rust, oil, and scale on the tube surface can cause laser focusing deviation, reduced cutting accuracy, and even nozzle clogging. Traditional chucks only have a clamping function and require manual pre-cleaning of the tube surface, which is inefficient and dependent on operator experience. At the same time, rigid clamping without lubrication can easily cause scratches on the tube surface, especially affecting precision tubes such as stainless steel and aluminum alloys.

[0003] Existing technologies lack chuck structures that can simultaneously achieve surface impurity cleaning and dynamic lubrication during the clamping process, resulting in unstable processing quality and high labor costs. Therefore, there is an urgent need for a laser tube cutting chuck to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a laser tube cutting chuck to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a laser tube cutting chuck, comprising a chuck body, the end face of which is provided with two sets of orthogonally distributed radial slide rails; a vertical jaw seat is mounted on the vertical radial slide rail, and a horizontal jaw seat is mounted on the horizontal radial slide rail; a vertical mounting through hole is opened in the middle of the vertical jaw seat; a horizontal mounting through hole is opened in the middle of the horizontal jaw seat; a scraper assembly is installed in both the vertical and horizontal mounting through holes, the scraper assembly including a scraper tongue, a positioning block, and an oil supply connecting rod; the scraper tongue is located at the front end of the scraper assembly, the scraper tongue has an arc-shaped flexible structure, and the scraper tongue body is designed in a three-fold shape; the scraper tongue has an oil guide channel extending along the curvature of the arc surface inside, and several oil outlet holes are evenly distributed on the front end face of the scraper tongue.

[0006] The present invention further describes that the oil delivery connecting rod is located at the rear end of the scraper assembly, the bottom of the oil delivery connecting rod body is machined with external threads, the oil delivery connecting rod passes through the mounting through hole and is fitted with a locking nut; an oil delivery hole is axially oriented through the center of the oil delivery connecting rod body.

[0007] The present invention further explains that the positioning block is located between the scraper tongue and the oil delivery connecting rod, and the positioning block is a square boss structure.

[0008] This utility model further illustrates that both the vertical mounting through hole and the horizontal mounting through hole are provided with a positioning groove on one side of their top, which has a limiting function.

[0009] The present invention further explains that the top surface of the mounting part is fixed with a first claw or a second claw by bolts. The first claw is mounted on a claw seat corresponding to the vertical slide rail, and the second claw is mounted on a claw seat corresponding to the horizontal slide rail. The first claw and the second claw form an orthogonal clamping structure.

[0010] This utility model further illustrates that: the oil delivery hole is connected to an oil box via a pipe, there are four oil boxes in total, and the oil boxes are evenly installed on the side of the chuck body by bolts.

[0011] Compared with existing technologies, the beneficial effects achieved by this invention are as follows: This invention adopts a claw structure integrating a flexible scraper and a flow-guiding lubrication system. The composite coating of the arc-shaped three-fold scraper tongue enables automatic cleaning of impurities on the pipe surface. Combined with the oil delivery connecting rod and flow-guiding oil channel design, a uniform lubricating film is applied simultaneously during clamping. This significantly improves the processing accuracy and efficiency of laser pipe cutting, and the structure is compact and easy to maintain. Attached Figure Description

[0013] The following detailed, non-limiting description of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0014] Please see Figure 1-4The present invention provides a technical solution: a laser tube cutting chuck, including a chuck body 1, with two sets of orthogonally distributed radial slide rails 2 on the end face of the chuck body 1; a vertical jaw seat 3 is mounted on the vertical radial slide rail 2, and a horizontal jaw seat 4 is mounted on the horizontal radial slide rail 2.

[0015] The vertical jaw seat 3 has a vertical mounting through hole 6 in the middle; the horizontal jaw seat 4 has a horizontal mounting through hole 7 in the middle; the top of the vertical jaw seat 3 is bolted with a first jaw 8, and the top of the horizontal jaw seat 4 is bolted with a second jaw 9, forming an orthogonal clamping structure with the first jaw 8 and the second jaw 9.

[0016] Both the vertical mounting through hole 6 and the horizontal mounting through hole 7 have a positioning groove 10 on one side of their top, which has a limiting function. Both the vertical mounting through hole 6 and the horizontal mounting through hole 7 have a scraper assembly 11 installed inside them. The scraper assembly 11 includes a scraper tongue 12, a positioning block 13, and an oil supply connecting rod 14. The oil supply connecting rod 14 is located at the rear end of the scraper assembly 11. The bottom of the oil supply connecting rod 14 is machined with an external thread 15. After the oil supply connecting rod 14 passes through the mounting through hole, it is fitted with a locking nut 16. The oil supply connecting rod 14 has an oil supply hole 17 axially penetrating through its center. The oil supply hole 17 is connected to an oil box 5 through a pipe. There are four oil boxes 5 in total. The oil boxes 5 are evenly installed on the side of the chuck body 1 by bolts. The oil box 5 is equipped with an oil pump to realize the directional delivery of lubricating oil.

[0017] The scraper tongue 12 is located at the front end of the scraper assembly 11. The scraper tongue 12 has an arc-shaped flexible structure (the radius of curvature matches the outer circle of the target pipe). The main body of the scraper tongue 12 is designed in a three-fold shape to form an elastic buffer structure and achieve flexible contact with the surface of the pipe. The scraper tongue 12 is provided with a guide oil channel 18 extending along the curvature of the arc surface. Several oil outlet holes 19 are evenly distributed on the front end face of the scraper tongue 12.

[0018] The positioning block 13 is located between the scraper tongue 12 and the oil supply connecting rod 14. The positioning block 13 has a square boss structure. When the scraper assembly 11 is installed, the positioning block 13 is embedded in the positioning groove 10 to form a circumferential limit, preventing the scraper assembly 11 from rotating and shifting.

[0019] Working principle: The drive mechanism drives the vertical jaw seat 3 and the horizontal jaw seat 4 to move synchronously radially along the radial slide rail 2. When the jaw seat approaches the pipe, the three-fold arc-shaped flexible structure of the scraper tongue 12 first contacts the surface of the pipe, and adaptively fits the irregular outer circle through elastic deformation. Its composite coating scrapes away impurities such as rust and oil.

[0020] Meanwhile, the oil box 5 supplies oil to the oil supply connecting rod 14 through the oil supply hole 17, and the lubricating oil overflows evenly from the oil outlet hole 19 on the front end face of the scraper tongue 12 through the guide oil channel 18, forming a lubricating film on the pipe surface. The positioning block 13 is embedded in the positioning groove 10 to prevent the scraper assembly 11 from rotating and to ensure that the scraper tongue 12 always makes stable contact along the circumference of the pipe.

[0021] Ultimately, the first jaw 8 and the second jaw 9 clamp the tube through an orthogonal clamping structure, achieving an integrated function of "impurity cleaning - dynamic lubrication - precise clamping", providing a clean and lubricated processing surface for laser cutting.
