Description

Technical Field

[0001] This utility model relates to the field of robotics, and in particular to an integrated cable retraction auxiliary mechanism. Background Technology

[0002] With the continuous development of production automation, robots are playing an increasingly important role in production. Monotonous and tedious tasks can be completed by robots, which not only saves manpower but also increases work efficiency.

[0003] When the robot's arm moves, it is connected to many cables that control the movement of the robot's arm. These cables are used to achieve the movement of the robot arm.

[0004] Existing robots typically use cable packages to install cables onto the robot. As the robot's arm extends away from itself, the cable also extends in that direction. When the robot's arm retracts towards itself, the cable may bend, become entangled with other cables, and be damaged, causing the robot's arm to malfunction and thus affecting the work process. Utility Model Content

[0005] To address the aforementioned technical problems, this application provides an integrated cable retraction auxiliary mechanism.

[0006] The integrated cable retraction auxiliary mechanism provided in this application adopts the following technical solution:

[0007] An integrated cable retraction auxiliary mechanism includes:

[0008] The housing is hollow inside, with openings at both ends, and a limiting shoulder is provided on the wall of the opening at one end of the housing.

[0009] A corrugated pipe, wherein the corrugated pipe is located inside the housing and both ends of the corrugated pipe extend outside the housing, and the cable is wrapped inside the corrugated pipe;

[0010] A limiting member, which is annular and fixedly connected to one end of the bellows away from the limiting shoulder and located outside the housing, wherein the maximum outer diameter of the limiting member is greater than the minimum inner diameter of the limiting shoulder;

[0011] An anti-reverse component, wherein the anti-reverse component is annular and fixedly connected to one end of the corrugated pipe having a limiting shoulder, wherein the maximum outer diameter of the anti-reverse component is greater than the minimum inner diameter of the limiting shoulder, and the anti-reverse component and the limiting component are located on both sides of the limiting shoulder;

[0012] A spring is sleeved on a bellows and located inside a housing. One end of the spring abuts against a limiting member, and the other end of the spring abuts against a limiting shoulder.

[0013] Preferably, the wall of the limiting shoulder is first concave inward and then expands outward in the direction from near the axial center of the housing to away from the axial center of the housing.

[0014] Preferably, a reinforcing rib is provided on the outer surface of the inwardly recessed position of the limiting shoulder, and multiple reinforcing ribs are provided at intervals along the circumference of the shell.

[0015] Preferably, the housing is integrally formed.

[0016] Preferably, the inner diameter of the housing gradually decreases slightly from the direction away from the limiting shoulder to the direction near the limiting shoulder.

[0017] Preferably, the maximum outer diameter of the spring is greater than the minimum inner diameter of the limiting shoulder.

[0018] Preferably, the minimum inner diameter of the hollow portion of the housing is greater than the maximum outer diameter of the spring.

[0019] Preferably, the bottom of the housing is provided with a mounting base for fixing to the robot arm. The mounting base is located at both ends of the housing, is semi-circular and fixedly connected to the bottom surface of the housing, and has mounting holes.

[0020] Preferably, the mounting hole is oblong.

[0021] In summary, this application includes the following beneficial technical effects:

[0022] During cable extension, the cable and corrugated tube are stretched to the right together. The limiting component and the anti-reverse component move to the right together on the corrugated tube. The spring is compressed by the limiting component and the limiting shoulder. When the cable and corrugated tube retract to the left, the spring extends, and the limiting component and the anti-reverse component reset to the left, bringing the corrugated tube and cable back to their original straight position in sync. This provides guidance for the movement of the cable, thereby reducing the possibility of the cable bending or getting tangled with other cables and thus reducing cable damage, allowing the robot arm to maintain normal operation.

[0023] When the anti-reverse component is limited by the limiting shoulder, it prevents the limiting component and the spring from detaching from the housing. Attached Figure Description

[0028] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0029] This application discloses an integrated cable retraction auxiliary mechanism.

[0030] Reference Figure 1-3 The integrated cable retraction auxiliary mechanism includes a housing 1, which is hollow and integrally formed. The housing 1 has an annular cross-section, with openings at both ends. A limiting shoulder 2 is provided on the wall of one opening of the housing 1. The wall of the limiting shoulder 2 is first concave inward and then expands outward from near the axial center of the housing 1 to away from the axial center. The inner diameter of the housing 1 gradually tapers from away from the limiting shoulder 2 to near the limiting shoulder 2.

[0031] A reinforcing rib 21 is provided on the outer surface of the inwardly recessed part of the limiting shoulder 2. Multiple reinforcing ribs are provided at intervals along the circumference of the shell to improve the structural strength of the limiting shoulder 2.

[0032] A bellows 3 is installed inside the housing 1. The bellows 3 is located inside the housing 1 and both ends of the bellows 3 extend out of the housing 1. The cable is wrapped inside the bellows 3. The bellows 3 and the cable slide together under the action of friction.

[0033] A limiting member 4 is provided on the bellows 3. The limiting member 4 is annular and is fixedly connected to the end of the bellows 3 away from the limiting shoulder 2. The maximum outer diameter of the limiting member 4 is greater than the minimum inner diameter of the limiting shoulder 2.

[0034] The bellows 3 is also provided with a backstop 5. The backstop 5 is annular and fixedly connected to one end of the bellows 3 with a limiting shoulder 2. The maximum outer diameter of the backstop 5 is greater than the minimum inner diameter of the limiting shoulder 2. The backstop 5 and the limiting member 4 are located on both sides of the limiting shoulder 2.

[0035] A spring 6 is fitted onto the bellows 3 and is located inside the housing 1. One end of the spring 6 abuts against the limiting member 4, and the other end of the spring 6 abuts against the limiting shoulder 2. When the anti-reverse member 5 is limited by the limiting shoulder 2, the limiting member 4 and the spring 6 stop moving, preventing the limiting member 4 and the spring 6 from detaching from the housing 1.

[0036] The maximum outer diameter of spring 6 is greater than the minimum inner diameter of the limiting shoulder 2. The minimum inner diameter of the hollow portion of housing 1 is greater than the maximum outer diameter of spring 6.

[0037] During the cable extension process, the cable and corrugated tube 3 are stretched to the right together. The limiting member 4 and the anti-reverse member 5 move to the right together on the corrugated tube 3. The spring 6 is compressed by the limiting member 4 and the limiting shoulder 2. When the cable and corrugated tube 3 retract to the left, the spring 6 extends, and the limiting member 4 and the anti-reverse member 5 reset to the left, bringing the corrugated tube 3 and the cable back to their straight position in sync. This provides guidance for the movement of the cable, thereby reducing the possibility of the cable bending or getting tangled with other cables and thus reducing cable damage, allowing the robot arm to maintain normal operation.

[0038] When the anti-reverse component 5 is limited by the limiting shoulder 2, it can prevent the limiting component 4 and the spring 6 from detaching from the housing 1.

[0039] The bottom of the housing 1 is provided with a mounting base 7 for fixing to the robot arm, and the mounting base 7 is located at both ends of the housing 1. The mounting base 7 is semi-circular and fixedly connected to the bottom surface of the housing 1. The mounting base 7 is provided with a mounting hole 71, which is an oblong hole. The mounting hole 71 facilitates the installation of the housing 1 onto the robot arm.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
