Description

Technical Field

[0001] This utility model relates to the field of cable fixing device technology, specifically a fixing device for robot power supply cables. Background Technology

[0002] Power supply cables are wires or cables used to transmit electrical energy, mainly used to transmit power from the power supply system to various electrical devices.

[0003] Robots used in industrial production cannot function without power cables. The purpose of these cables is to deliver power to the robot to ensure its normal operation. Since robots often make bending and rotating movements during operation, the cables will move along with them. To avoid the cables becoming tangled on the robot, the current practice is to fix the cables to the robot.

[0004] As described in Chinese patent application CN202120041630.9, which discloses an industrial robot and its cable fixing device, the cable fixing device includes an upper clamping plate, a lower clamping plate, and at least one rotating column. The upper and lower clamping plates are detachably connected and can be combined to form a through-hole for the cable to pass through. All rotating columns are rotatably disposed within the through-hole, and each rotating column is rotatably connected to at least one of the upper and lower clamping plates. When the cable moves axially along the through-hole, the cable pulls the rotating column to rotate radially around the through-hole by the friction between the cable and the rotating column. In other words, the rotating column rotates with the movement of the cable, reliably guiding the cable movement and avoiding excessive friction between the rotating column and the cable. The cable fixing device provided by this invention uses a rolling method to fix the cable, replacing the existing snap-fit ​​fixing method, preventing the cable from being pulled apart due to excessive friction between the cable and the cable fixing device, thereby effectively preventing cable damage.

[0005] Based on the above search, we found that the application still has certain shortcomings:

[0006] First, the above technology can only fix the cable that is compatible with the distance between the two rotating columns. When the diameter of the cable is not compatible with the distance between the two rotating columns, it is difficult to fix the cable, resulting in a deterioration in the effect of the device.

[0007] Second, in the above technology, the cable path is a straight line, which is determined when it is placed between two rotating pillars. When it is necessary to change the direction of the cable, the cable can only be bent at either rotating pillar, which will undoubtedly damage the cable and is not conducive to the stability of the cable. Utility Model Content

[0008] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0009] To achieve the above objectives, this utility model provides the following technical solution: a fixing device for a robot power supply cable, comprising a fixed frame and a movable frame, wherein the movable frame is disposed in an adjustment groove opened inside the fixed frame; sliding grooves are provided on the inner top wall and inner bottom wall of the movable frame, and a cable clamping assembly is slidably connected inside the sliding groove; the cable clamping assembly includes two sliding plates and a rotating rod rotatably connected between the two sliding plates; a return spring is fixed on one side of one sliding plate, and the other end of the return spring is fixedly connected to the side wall of the sliding groove; a rotating shaft is fixed at the center position of the top and bottom of the movable frame, and a positioning hole is provided in an annular shape on the rotating shaft, into which a pin disposed inside the fixed frame is inserted.

[0010] As a further embodiment of this utility model: two sliding grooves are respectively opened on the inner top wall and inner bottom wall of the movable frame, and the two sliding grooves located on the inner top wall and inner bottom wall of the movable frame and corresponding to each other are a group, and two sets of cable clamping assemblies are provided between each group of sliding grooves.

[0011] As a further embodiment of this utility model: both sides of the sliding plate are integrally formed with limiting blocks, both sides of the inner wall of the sliding groove are provided with limiting grooves, the sliding plate is slidably connected in the sliding groove, and the limiting blocks are slidably connected in the limiting grooves.

[0012] As a further embodiment of this utility model: a fixing post is fixed on one side of the sliding plate, and an inner ring of a bearing is fixedly sleeved on the surface of the fixing post. The top and bottom of the rotating rod are both provided with inner grooves. The fixing post is connected to the inner groove of the rotating rod through a bearing, and the outer ring of the bearing is fixed on the inner wall of the inner groove.

[0013] As a further embodiment of this utility model: a cavity is provided in the inner cavity of the top and bottom of the fixed frame, and a second reset spring is fixed inside the cavity. A pin is fixed at the other end of the second reset spring. One end of the pin is a round head structure, and the round head structure of the pin moves through the cavity and is inserted into the positioning hole of the rotating shaft.

[0014] As a further embodiment of this utility model: the left and right sides of the movable frame are designed with arc structures, the left and right sides of the inner wall of the adjustment groove are also designed with arc structures, and the left and right sides of the movable frame are far away from the left and right sides of the inner wall of the adjustment groove.

[0015] As a further embodiment of this utility model: a mounting plate is fixed to one side of the fixed frame, and two mounting holes are provided on the mounting plate for the insertion of screws.

[0016] As a further embodiment of this invention, the surface of the rotating rod is designed to have a smooth mirror-like structure.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. In this application, by designing a movable frame, sliding groove, cable clamping assembly, and a return spring, the fixed frame is fixed to the robot. When the cable is inserted, the rotating rod can move in the sliding groove, thereby enabling the two rotating rods to move closer or further apart. This allows for the rolling fixation of cables of different diameters, making it more versatile. Furthermore, the restoring force generated by the return spring makes the cable more stable when it is rolled and fixed, ultimately fixing the power cable at the designated position on the robot.

[0019] Second, in this application, by designing a fixed frame, a movable frame, a rotating shaft, and a pin, the movable frame can rotate inside the fixed frame to adjust the orientation of the fixed cable. This avoids bending of the cable and achieves a change in cable orientation. This method is more practical, avoids damage to the cable caused by bending, and ensures stable operation of the cable.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-6 A device for fixing a robot power cable includes a fixed frame 1 and a movable frame 3. The movable frame 3 is disposed in an adjustment groove 2 inside the fixed frame 1. Sliding grooves 5 are provided on both the inner top and bottom walls of the movable frame 3. A cable clamping assembly is slidably connected inside the sliding grooves 5. The cable clamping assembly includes two sliding plates 8 and a rotating rod 6 rotatably connected between the two sliding plates 8. The surface of the rotating rod 6 is designed with a smooth mirror surface, which facilitates cable movement and avoids damage to the cable surface. The sliding plate 8 has a return spring 11 fixed on one side, and the other end of the return spring 11 is fixedly connected to the side wall of the sliding groove 5. When the sliding plate 8 moves toward the side of the return spring 11, it can be affected by the restoring force of the return spring 11, thereby using the restoring force generated by the return spring 11 to form a certain clamping force on the cable. The top and bottom center positions of the movable frame 3 are both fixed with a rotating shaft 7. The rotating shaft 7 has a positioning hole 701 in a ring shape, and a pin 14 set inside the fixed frame 1 is inserted into the positioning hole 701.

[0030] Please see Figure 2 and Figure 3 In this embodiment, two sliding grooves 5 are respectively opened on the inner top wall and inner bottom wall of the movable frame 3. The two sliding grooves 5 located on the inner top wall and inner bottom wall of the movable frame 3 and corresponding to each other are a group. Two sets of cable clamping assemblies are provided between each group of sliding grooves 5.

[0031] Specifically, the active frame 3 contains multiple sets of cable clamping components, which can achieve relatively rolling fixation of multiple cables, resulting in lower usage costs and better performance.

[0032] Please see Figure 2 , Figure 3 and Figure 4In this embodiment, both sides of the sliding plate 8 are integrally formed with limiting blocks 801, and both sides of the inner wall of the sliding groove 5 are provided with limiting grooves 501. The sliding plate 8 is slidably connected in the sliding groove 5, and the limiting blocks 801 are slidably connected in the limiting grooves 501.

[0033] Specifically, the movement trajectory of the sliding plate 8 can be limited by the limit block 801 and the limit groove 501, so that the sliding plate 8 can move in a specified direction and the stability of the sliding plate 8 during movement can be guaranteed.

[0034] Please see Figure 4 In this embodiment, a fixing post 9 is fixed on one side of the sliding plate 8. The inner ring of the bearing 10 is fixedly sleeved on the surface of the fixing post 9. The top and bottom of the rotating rod 6 are provided with inner grooves. The fixing post 9 is connected to the inner groove of the rotating rod 6 through the bearing 10, and the outer ring of the bearing 10 is fixed on the inner wall of the inner groove.

[0035] Specifically, the rotating rod 6 can rotate between the two sliding plates 8 via the bearing 10. During rotation, it is supported and stabilized by the fixed column 9, ensuring the stability of the rotating rod 6 during rotation.

[0036] Please see Figure 5 and Figure 6 In this embodiment, cavities 12 are provided in the inner cavities at the top and bottom of the fixed frame 1. A second reset spring 13 is fixed inside the cavity 12. A pin 14 is fixed at the other end of the second reset spring 13. One end of the pin 14 has a round head structure, and the round head structure of the pin 14 moves through the cavity 12 and is inserted into the positioning hole 701 of the rotating shaft 7.

[0037] Specifically, when the ejector pin 14 is abutted by the rotating shaft 7, one end of the ejector pin 14 extends into the cavity 12 and compresses the return spring 13. When the round end of the ejector pin 14 is re-engaged into the positioning hole 701, the restoring force of the return spring 13 can push the part of the ejector pin 14 that was originally inserted out of the cavity 12, and make the round end of the ejector pin 14 re-engage into the positioning hole 701, thus achieving stable engagement.

[0038] Please see Figure 1 In this embodiment, the left and right sides of the movable frame 3 are designed with arc structures, and the left and right sides of the inner wall of the adjustment groove 2 are also designed with arc structures. Furthermore, the left and right sides of the movable frame 3 are far away from the left and right sides of the inner wall of the adjustment groove 2.

[0039] Specifically, the left and right sides of the movable frame 3 are far away from the adjustment groove 2, which is conducive to the movable frame 3 rotating in the adjustment groove 2.

[0040] Please see Figure 1In this embodiment, a mounting plate 4 is fixed to one side of the fixed frame 1. The mounting plate 4 has two mounting holes for inserting screws.

[0041] Specifically, mounting plate 4 is used to fix the robot or equipment. The fixing method can be screw fixing or welding fixing. When mounting plate 4 is fixed, the entire device is fixed and the cables are also fixed at this point.

[0042] When using:

[0043] Fix the mounting plate 4 to the robot. The fixing method can be either screw fixing or welding. After fixing, pass the robot power cable between two adjacent rotating rods 6 (cable clamping assembly). When the cable diameter is large, the cable will spread the two rotating rods 6 and cause the two sliding plates 8 to move away from each other in the sliding groove 5. This allows the restoring force of the return spring 11 to be applied to the rotating rods 6, so that the two rotating rods 6 can generate a certain clamping force on the cable. Conversely, when the cable diameter is small, the two sliding plates 8 will move closer to each other, causing the two rotating rods 6 to move closer to each other to clamp the cable.

[0044] When the cable is pulled, the sliding force of the cable will act on the rotating rod 6, thereby driving the rotating rod 6 to rotate, so as to achieve smooth sliding of the cable and reduce friction.

[0045] Depending on the actual installation situation or on-site requirements, when it is necessary to change the orientation of the cable, simply rotate the movable frame 3. The movable frame 3 rotates via the rotating shaft 7. When the rotating shaft 7 rotates, it can push a part of the ejector pin 14 into the cavity 12. When the rotation angle is appropriate, the ejector pin 14 is reset by the reset spring 13 and springs back into the positioning hole 701, thereby locking the rotating shaft 7 and preventing further rotation. This fixes the position of the movable frame 3. When the movable frame 3 rotates, the angle of the rotating rod 6 will also change. This change in the angle of the rotating rod 6 can be used to change the orientation of the cable, preventing the cable from bending and ensuring the safety of the cable.

[0046] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
