Description

Technical Field

[0001] This utility model relates to the field of robots, and in particular to a split-type cable guiding 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 arm moves, it is connected to many cables that control the movement of the robot 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 a split-type cable guiding mechanism.

[0006] The split-type cable guiding mechanism provided in this application adopts the following technical solution:

[0007] A split-type cable guiding mechanism includes a housing with a hollow interior. Both ends of the housing are open, and the walls of the openings at both ends of the housing are recessed towards the central axis of the housing to form limiting shoulders.

[0008] 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;

[0009] A limiting member, which is annular and fixedly connected to the bellows, is located between two limiting shoulders, and the maximum outer diameter of the limiting member is greater than the minimum inner diameter of the limiting shoulders.

[0010] A spring is sleeved on a bellows and located between two limiting shoulders. One end of the spring abuts against a limiting member, and the other end of the spring abuts against a limiting shoulder.

[0011] 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.

[0012] 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.

[0013] Preferably, the maximum outer diameter of the spring is greater than the minimum inner diameter of the limiting shoulder.

[0014] Preferably, the inner diameter of the hollow portion of the housing is greater than the maximum outer diameter of the spring.

[0015] Preferably, the housing includes a first unit housing and a second unit housing that can be assembled.

[0016] Preferably, the first unit housing is provided with connecting ear plates on both radial sides, and the second unit housing is provided with connecting ear plates on both radial sides. The connecting ear plates correspond to the first connecting ear plates, and the connecting ear plates are fixed to the corresponding connecting ear plates by screws.

[0017] Preferably, a connecting ear plate three is provided at the outward extension position of the limiting shoulder of the unit housing one, and a connecting ear plate four is provided at the outward extension position of the limiting shoulder of the unit housing two. The connecting ear plate three and the connecting ear plate four correspond to each other, and the connecting ear plate three and the corresponding connecting ear plate four are fixed by screws.

[0018] Preferably, the bottom of the housing is provided with a mounting base for fixing the robot arm. The mounting base is located at both ends of the housing.

[0020] In summary, this application includes the following beneficial technical effects:

[0021] During the cable extension process, the cable and corrugated tube are stretched to the right together, and the limiting component moves to the right along with 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, the limiting component resets to the left, and the corrugated tube and cable are synchronously and smoothly reset, providing guidance for the movement of the cable, thereby reducing the possibility of the cable bending or getting tangled with other cables and being damaged, reducing cable damage, and enabling the robot arm to maintain normal operation.

[0027] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0028] This application discloses a split-type cable guiding mechanism.

[0029] Reference Figure 1-3 The split-type cable guiding mechanism includes a housing 1, which is hollow inside. The cross-section of the housing 1 is annular, and both ends of the housing 1 are open. The walls of the openings at both ends of the housing 1 are recessed towards the central axis of the housing 1 to form limiting shoulders 2. The walls of the limiting shoulders 2 are first recessed inward and then expanded outward in the direction from near the axial center of the housing 1 to away from the axial center of the housing 1.

[0030] A reinforcing rib 21 is provided on the outer surface of the inwardly recessed part of the limiting shoulder 2. Multiple reinforcing ribs 21 are provided at intervals along the circumference of the shell 1 to improve the structural strength of the limiting shoulder 2.

[0031] 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.

[0032] A limiting element 4 is provided on the corrugated pipe 3. The limiting element 4 is annular and fixedly connected to the corrugated pipe 3. The limiting element 4 is located between two limiting shoulders 2. The maximum outer diameter of the limiting element 4 is greater than the minimum inner diameter of the limiting shoulders 2.

[0033] A spring 5 is fitted onto the bellows 3 and is located inside the housing 1. The spring 5 is positioned between two limiting shoulders 2, with one end of the spring 5 abutting against the limiting member 4 and the other end abutting against the limiting shoulder 2. The maximum outer diameter of the spring 5 is greater than the minimum inner diameter of the limiting shoulder 2. The inner diameter of the hollow portion of the housing 1 is greater than the maximum outer diameter of the spring 5. When the limiting member 4 is limited by the left limiting shoulder 2, the limiting member 4 and the spring 5 are prevented from detaching from the housing 1.

[0034] During the cable extension process, the cable and corrugated tube 3 are stretched to the right together, and the limiting member 4 moves to the right together on the corrugated tube 3. The spring 5 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 5 extends, and the limiting member 4 resets to the left, bringing the corrugated tube 3 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.

[0035] When the limiting member 4 is limited by the limiting shoulder 2 on the left, the limiting member 4 and the spring 5 are prevented from detaching from the housing 1.

[0036] The housing 1 includes a unit housing 11 and a unit housing 2 12 that can be assembled.

[0037] Connecting ear plates 111 are provided on both radial sides of unit housing 11, and connecting ear plates 121 are provided on both radial sides of unit housing 12. Connecting ear plates 121 correspond to connecting ear plates 111 and are fixed to the corresponding connecting ear plates 111 by screws.

[0038] A connecting ear plate 3 112 is provided at the outward extension position of the limiting shoulder 2 of the unit housing 11, and a connecting ear plate 4 122 is provided at the outward extension position of the limiting shoulder 2 of the unit housing 2. The connecting ear plate 3 112 and the connecting ear plate 4 122 correspond to each other and are fixed by screws.

[0039] The modular housing 1 facilitates the assembly of cables, corrugated pipes 3, springs 5, and limiting components 4.

[0040] The bottom of the housing 1 is provided with a mounting base 6 for fixing the robot arm. The mounting base 6 is located at both ends of the housing 1. The mounting base 6 includes an arc-shaped unit base 61 and a unit base 62. The unit base 61 and the unit base 62 are connected in a semi-arc shape. The unit base 61 is fixedly connected to the bottom surface of the unit housing 11, and the unit base 62 is fixedly connected to the bottom surface of the unit housing 12. Both the unit base 61 and the unit base 62 are provided with mounting holes 63. The mounting holes 63 are oblong holes, which facilitate the adjustment of the installation position according to the situation.

[0041] The housing 1 can be mounted on the robot arm via the mounting base 6.

[0042] 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.
