Description

Technical Field

[0001] The utility model belongs to the technical field of rotary joints, in particular to a 360-degree rotary joint with a bearing. Background Art

[0002] During the operation of the equipment, as the equipment moves, the cable also needs to move with it. In the cable protection system, the protective cable is usually a cable sheathed corrugated hose, and the 360° swivel joint is used for this. It needs to meet 360° rotation and is usually used on robot arms.

[0003] The 360° connectors currently on the market are mainly used to adjust the outlet position of the hose connector during the installation process. They generally have the disadvantage of being not flexible enough in rotation. At the same time, the frequency of use of this rotating structure is not high, and it is only used during the installation process. Therefore, it is not suitable for the robot industry which requires flexible rotation and a very high frequency. Therefore, there is an urgent need for a connector that can meet the requirements of both flexible rotation and frequency on the robot arm. Utility Model Content

[0004] In view of the problems raised by the above background technology, the purpose of the present utility model is to provide a 360° rotating joint with a bearing.

[0007] It is further defined that the bolt sleeve is mounted on the support by thread locking. Such a structural design makes the installation more secure.

[0008] It is further defined that thread glue is applied between the bolt sleeve and the support. Such a structural design improves the sealing effect of the connection.

[0009] It is further defined that the bolt sleeve is provided in a hexagonal flange structure. Such a structural design is convenient for installing plate products and is convenient for use in different occasions.

[0014] 4. The overall weight of the utility model is light, which effectively meets the weight requirements of the operating equipment in the robot industry;

[0015] 5. The utility model is easy to assemble and operate. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The present invention can be further described by the non-limiting embodiments given in the accompanying drawings;

[0017] Figure 1 This is a schematic structural diagram of a 360° bearing swivel joint according to an embodiment of the utility model;

[0018] The main component symbols are described as follows:

[0019] Steering nut 1, support 2, bearing groove 3, bearing glue 4, deep groove ball bearing 5, shaft retaining ring 6, bolt sleeve 7, thread glue 8. DETAILED DESCRIPTION

[0020] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0021] like Figure 1 As shown, the utility model has a 360° bearing swivel joint, a support 2 is sleeved on the top of the steering nut 1, a bearing groove 3 is provided between the steering nut 1 and the support 2, the inner wall of the bearing groove 3 is evenly coated with bearing glue 4, a deep groove ball bearing 5 is installed in the bearing groove 3, the steering nut 1 is provided with a groove on the upper side of the deep groove ball bearing 5, a shaft retaining spring 6 is installed in the groove, and a bolt sleeve 7 is installed on the outer top of the support 2.

[0022] Preferably, the bolt sleeve 7 is installed on the support 2 by thread locking. Such a structural design makes the installation more secure. In fact, other connection structural shapes of the bolt sleeve 7 and the support 2 can also be considered according to specific circumstances.

[0023] Preferably, thread glue 8 is applied between bolt sleeve 7 and support 2. Such structural design improves the sealing effect of connection. In fact, other sealing structural shapes of bolt sleeve 7 and support 2 can also be considered according to specific circumstances.

[0024] Preferably, the bolt sleeve 7 is provided with a hexagonal flange structure. Such a structural design is convenient for installing plate products and is convenient for use in different occasions. In fact, other structural shapes of the bolt sleeve 7 can also be considered according to specific circumstances.

[0025] In this embodiment, during assembly, the support 2 is inserted into the steering nut 1, and the bearing glue 4 is applied to the bearing groove 3 formed between the steering nut 1 and the support 2. Then the deep groove ball bearing 5 is inserted into the bearing groove 3, and the shaft retaining ring 6 is inserted into the retaining groove of the steering nut 1. Finally, the bolt sleeve 7 is inserted into the support 2, screwed into the corresponding position, and tightened according to the torque. If sealing is required, thread glue 8 can be applied, and the installation is completed.

[0026] The bearing glue 4 needs to be evenly applied to fix the deep groove ball bearing 5.

[0027] Among them, both the bearing glue 4 and the thread glue 8 need to meet the requirements of long-term use.

[0028] The deep groove ball bearing 5 is fixed by applying bearing glue 4. A high-strength bearing glue is selected without disassembling the deep groove ball bearing 5. The glue cures quickly and is suitable for filling small and medium gaps. An accelerator is required before applying the glue to accelerate the curing of the glue and achieve better fixing and reliability.

[0029] The deep groove ball bearing 5 is fixed by using a shaft retaining ring 6 to avoid axial movement of the inner ring of the deep groove ball bearing 5. The outer ring of the deep groove ball bearing 5 is fixed by the threaded fastening of the support 2 and the bolt sleeve 7. The two are tightly matched in structure, which effectively avoids axial movement and can withstand good axial pressure.

[0030] The 360° bearing swivel joint is usually used with other hose connectors to connect the hose. This combination will lengthen the overall joint length. Therefore, compact structure is the key to the design. The 360° bearing swivel joint has a small number of parts and only 3 machined parts. In addition to 2 parts for matching equipment, the entire part connected to the bearing is only one metal part. Therefore, the structure is compact and small, effectively reducing the overall height.

[0031] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
