Technical Field

[0001] The utility model belongs to the technical field of eccentric tube processing, in particular to a sleeve connection structure for producing eccentric tubes. Background Art

[0002] In the process of implementing the utility model, the inventor found that the prior art has at least the following problems:

[0003] In the traditional technology, when processing the eccentric tube, the eccentric tube needs to be positioned and clamped. The traditional method is to clamp the eccentric tube with a chuck. The clamping force of the chuck is difficult to control, and the eccentric tube is easily squeezed and deformed. At the same time, the chuck clamps the eccentric tube in the center, which is not convenient for eccentric processing.

[0004] CN204140002U-A hydraulic threading machine that can be used to clamp eccentric pipe fittings, discloses a hydraulic threading machine that can be used to clamp eccentric pipe fittings, including: a base, a rotating main tongs, an adjustable clamping back tongs and a hydraulic control system. An oil tank and a hydraulic power source are provided in the base. The oil pipelines and wires concealedly installed in the machine connect the hydraulic power source, the rotating main tongs, the adjustable clamping back tongs and the hydraulic control system together, but cannot solve the above technical problems.

[0005] The technical problem to be solved by the utility model is to provide a sleeve joint structure for producing eccentric pipes, which can reliably position pipe fittings, prevent the pipe fittings from being squeezed and deformed, and ensure stable and reliable processing; meanwhile, it is convenient to process eccentric holes.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is: a sleeve connection structure for producing eccentric pipes, having:

[0007] A sleeve, which is in a circular ring shape, and the outer circumference of the sleeve can be connected to the machine tool;

[0008] The mounting hole is arranged in the sleeve; the mounting hole can be matched with the eccentric tube; the sleeve center of the sleeve and the hole center of the mounting hole are offset.

[0009] A series of slots are arranged on the outer circumference of the sleeve, and the slots extend from the first end to the second end of the sleeve; the slots extend inwardly from the outer circumference of the sleeve to near the mounting hole.

[0010] The outer circumference of the sleeve is also provided with a through groove, and the through groove penetrates the sleeve; the through groove extends inward from the outer circumference of the sleeve to communicate with the mounting hole.

[0011] The outer circumference of the sleeve is provided with seven slots.

[0012] One through groove and seven slots are evenly distributed on the outer circumference of the sleeve.

[0013] The two end surfaces of the sleeve are planes.

[0014] One of the above technical solutions has the following advantages or beneficial effects: it can reliably position the pipe fitting, prevent the pipe fitting from being squeezed and deformed, and the processing is stable and reliable; at the same time, it is easy to process the eccentric hole.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figures 1-2 , a sleeve joint structure for producing eccentric pipes, comprising:

[0020] The sleeve 1 is annular, and the outer periphery of the sleeve 1 can be connected to the machine tool; the mounting hole 12 is arranged in the sleeve 1; the mounting hole 12 can be adapted to the eccentric tube; the sleeve center 14 of the sleeve 1 and the hole center 121 of the mounting hole 12 are offset. By installing the eccentric tube into the mounting hole 12, the sleeve 1 is connected to the machine tool, which plays a role of indirectly clamping the eccentric tube, can reliably position the pipe fitting, prevent the pipe fitting from being squeezed and deformed, and the processing is stable and reliable. At the same time, the sleeve center 14 of the sleeve 1 and the hole center 121 of the mounting hole 12 are offset, which is convenient for processing the eccentric hole.

[0021] A series of slots 11 are arranged on the outer circumference of the sleeve 1, and the slots 11 extend from the first end to the second end of the sleeve 1; the slots 11 extend inward from the outer circumference of the sleeve 1 to near the mounting hole 12. The slots 11 can expand when the eccentric tube is installed, and the connection is more stable and reliable.

[0022] The outer circumference of the sleeve 1 is also provided with a through groove 13, which runs through the sleeve 1; the through groove 13 extends inward from the outer circumference of the sleeve 1 to communicate with the mounting hole 12. The through groove 13 can also expand when the eccentric tube is installed, and the connection is more stable and reliable. At the same time, it can also meet the installation requirements of eccentric tubes of different sizes.

[0023] The outer circumference of the sleeve 1 is provided with seven slots 11. One through slot 13 and the seven slots 11 are evenly distributed on the outer circumference of the sleeve 1. Both end surfaces of the sleeve 1 are planes. One through slot 13 and the seven slots 11 are evenly distributed on the outer circumference of the sleeve 1. This allows the sleeve 1 to expand evenly when expanding.

[0024] After adopting the above structure, the pipe fitting can be reliably positioned to prevent the pipe fitting from being squeezed and deformed, and the processing is stable and reliable; at the same time, it is convenient to process the eccentric hole.
