Description

Technical Field

[0001] This utility model mainly relates to a sleeve used to stabilize pipes on a laser pipe cutting machine. Background Technology

[0002] In the production process of laser tube cutting machine, there is a device used to stabilize the tube, namely the sleeve. The accuracy and stability of the sleeve affect the accuracy and stability of the produced product.

[0003] In traditional laser tube cutting machines, the sleeve is typically a replaceable metal or non-metal cylindrical structure with an outer diameter adapted to the base and an inner diameter adapted to the tube being cut. This design places extremely high demands on the dimensional accuracy, roughness, and coaxiality of the sleeve's outer cylindrical surface and inner bore. Furthermore, due to unavoidable differences in coaxiality, the same sleeve often fails to achieve the same position after disassembly and reassembly due to its own rotation, leading to equipment downtime and readjustment, severely impacting efficiency. Additionally, each sleeve corresponds to only one tube diameter; in large-scale production of multiple specifications, a large number of sleeves with different inner diameters are needed to meet the production needs of various tube sizes, significantly increasing management and storage costs during production. Utility Model Content

[0004] To overcome the above shortcomings, this patent provides a new type of multi-hole sleeve for laser tube cutting machines, which solves the problems of high manufacturing precision requirements, poor position repeatability and low applicability of previous sleeves. It is a multi-hole sleeve with self-positioning and low manufacturing precision requirements, and a matching locking device.

[0005] The purpose of this utility model is achieved as follows:

[0006] A novel multi-diameter sleeve for laser tube cutting machines includes a sleeve base with a through hole in the front-to-back direction. The bottom of the through hole is inverted conical, and a sleeve is placed in the middle of the through hole. The sleeve is a regular prism, with one corner of the sleeve locked at the bottom of the through hole. Each corner of the sleeve has a hole with a different diameter, through which a tube is inserted. The top of the through hole is horizontal, and a locking block is provided between the top of the through hole and the top of the sleeve. The top of the locking block is horizontal, and the bottom is a conical notch. The conical notch and the bottom of the through hole simultaneously lock the sleeve from above and below. A locking screw hole is provided at the top of the sleeve base, through which a locking screw is inserted downward to push the locking block downward and hold the sleeve in place.

[0007] Each facet of the sleeve is etched with the corresponding working position aperture.

[0008] A rectangular observation hole is opened on the side of the sleeve base.

[0009] The beneficial effects of this utility model are:

[0010] 1. The traditional sleeve is changed from a cylindrical shape to a regular prism shape. The bottom of the through hole of the sleeve base is consistent with the shape of the outer cylindrical surface of the sleeve, so as to achieve self-positioning under the pressure of the tightening mechanism. The same sleeve can maintain the consistency of position when changing different pipe diameters or before and after disassembly.

[0011] 2. The traditional locking method of the sleeve is changed to a locking screw pushing the locking block, and the sleeve base groove, which is consistent with the shape of the outer cylindrical surface of the sleeve, locks the sleeve. This can distribute the force and reduce the deformation of sleeves of different materials due to the locking device.

[0012] 3. A hole is drilled on the end face of each edge of the sleeve, and the diameter of each hole is different, so that the same sleeve can be used for different pipes. Taking a regular hexagonal prism as an example, six different pipes with different hole diameters can be used on one sleeve at the same time. The hole diameter corresponding to the working position is etched on each face of the regular prism sleeve, and a rectangular through hole is drilled on the side of the sleeve base, which can easily confirm the hole diameter of the sleeve currently in use.

[0013] 4. The diameter of the sleeve head end is reduced inward, while retaining a portion of the hole wall. When cutting at a suitable position, this portion of the hole wall can support the pipe and limit its sway, while avoiding the problem of pipe sagging when cutting long products.

[0017] See Figure 1 and Figure 2 This utility model relates to a novel multi-diameter sleeve for a laser tube cutting machine. It includes a sleeve base 1 with through holes 2 in the front-rear direction. The bottom of the through hole 2 is inverted conical, and the middle of the through hole 2 is used to place a sleeve 3. The sleeve 3 is a regular prism, and one corner of the sleeve 3 can be engaged with the bottom of the through hole 2. Due to its own weight and the angle of its edge, the sleeve 3 achieves preliminary self-positioning. When placing tubes 4 of different diameters on the same sleeve 3, the sleeve 3 maintains consistent position before and after assembly and disassembly.

[0018] The sleeve 3 has a hole on the end face of each edge, and the diameter of each hole is different, so that the same sleeve 3 can be used for different pipes 4. Taking a regular hexagonal prism as an example, if the sleeve 3 is a regular hexagonal prism, there are six holes on the sleeve 3, so that six different diameter pipes 4 can be inserted.

[0019] Each facet of the sleeve 3 is etched with the corresponding working position aperture, and a rectangular observation hole 5 is also opened on the side of the sleeve base 1, through which the size of the aperture being used can be seen.

[0020] The top of the through hole 2 is horizontally positioned, and a locking block 6 is provided between the top of the through hole 2 and the top of the sleeve 3. The top of the locking block 6 is horizontal, and the bottom is a conical notch 7. The conical notch 7 and the bottom of the through hole 2 simultaneously lock the sleeve 3 from above and below. In addition, a locking screw hole 8 is provided on the top of the sleeve base 1. The locking screw 9 is inserted downward through the locking screw hole 8. The screw is turned down with a wrench, which pushes the locking block 6 downward, pressing against the sleeve 3. Then, the tube 4 can be inserted from the front end through the end face of the edge.
