Description

Technical Field

[0001] This utility model relates to the field of industrial robot technology, specifically to a robot walking axis that is easy to install. Background Technology

[0002] In the current era of rapid industrial automation development, the robot's walking axis, as a key component for realizing robot spatial movement, directly affects production efficiency and equipment reliability in terms of ease of installation and operational stability.

[0003] The existing patent document CN217434374U discloses a robot walking axis that is easy to install. This utility model is equipped with a spring, a first fixed bracket, and a second fixed bracket. Under the action of the spring, the first fixed bracket and the second fixed bracket are driven to extend and retract, which plays a buffering role during the movement of the robot walking axis, improving the practicality of the device. The first fixed bracket and the second fixed bracket are set to fix the bottom of the robot, preventing the robot from tipping over during movement.

[0004] However, existing robot walking axes that are easy to install rely on the restoring force of springs to fix the robot, which has obvious stability defects. On the one hand, the springs are prone to fatigue deformation during long-term and frequent compression and rebound, resulting in a decrease in the elastic coefficient and a gradual weakening of the fixing force. As the usage time increases, the restoring force of the springs can hardly provide a stable fastening effect continuously. The robot is prone to loosening and displacement during operation, affecting the accuracy of operation and even causing equipment failure. On the other hand, the direction of the spring's restoring force is relatively unidirectional, making it difficult to constrain the robot in multiple dimensions. When the robot performs complex movements or is subjected to lateral external forces, the spring's restoring force alone cannot effectively limit its swaying. Especially in high-speed movement or sudden stop and turn conditions, the robot will produce a large deviation, which not only reduces operational stability but may also cause safety hazards such as collisions and interference. In addition, the preload of the spring is difficult to adjust precisely. Excessive preload may damage the robot's mounting parts, while insufficient preload cannot guarantee the fixing effect, further exacerbating the shortcomings of the existing technology in terms of stability.

[0005] (a) Technical problems to be solved

[0006] The purpose of this invention is to provide a robot walking axis that is easy to install, in order to solve the problem mentioned in the background art that the existing robot walking axes that are easy to install use the restoring force of springs to fix the robot, resulting in poor stability.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a robot walking axis that is easy to install, including a walking axis mounting base, a positioning motor is installed on one side inside the walking axis mounting base, and a double-sided lead screw is fixedly connected to the transmission end of the positioning motor;

[0009] The end of the double-sided lead screw away from the positioning motor is connected to the inner wall of the traveling shaft mounting base via a bearing. The outer surface of the double-sided lead screw is symmetrically connected to two moving blocks via threads. A positioning plate is fixedly connected to one side of each moving block.

[0010] As a further improvement to the above solution, a connecting block is connected to the side of the positioning plate away from the moving block, and a connecting rod is horizontally arranged inside the traveling shaft mounting seat. The connecting block is in clearance fit with the connecting rod through a sliding sleeve hole.

[0011] As a further improvement to the above solution, rubber pads are attached to the opposite surfaces of the two positioning plates, the surface of the rubber pads is densely covered with anti-slip textures, and an anti-slip pad is attached to the bottom of the inside of the travel shaft mounting seat.

[0012] As a further improvement to the above solution, a walking shaft fixing base plate is provided below the walking shaft mounting seat, and a shock-absorbing pad is clamped between the walking shaft mounting seat and the walking shaft fixing base plate. The four corners of the shock-absorbing pad are provided with preset grooves.

[0013] As a further improvement to the above solution, a shock absorber is embedded inside the preset groove, and the two ends of the shock absorber are respectively fixed to the bottom surface of the travel shaft mounting seat and the upper surface of the travel shaft fixing base plate.

[0014] As a further improvement to the above solution, a central groove is provided at the center of the shock-absorbing pad, and a supporting ring is provided on the upper surface of the traveling shaft fixing base plate inside the central groove.

[0015] As a further improvement to the above solution, a support disc is connected to the middle of the bottom end of the traveling shaft mounting base, and the support disc and the support ring are connected by a sliding sleeve with clearance fit.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This easy-to-install robot walking axis, through the linkage structure of the positioning motor and the double-sided lead screw, significantly improves installation efficiency and operational stability. After the positioning motor is started, the double-sided lead screw rotates synchronously with high-precision thread transmission, driving the two moving blocks on both sides to move towards or away from each other in a symmetrical and uniform manner along the lead screw axis, thereby quickly adjusting the spacing of the positioning plates. This greatly reduces the equipment installation and debugging time, and is especially suitable for the rapid adaptation and installation of robots of various specifications. This structural design not only achieves rapid installation, but also ensures that the positioning components of the robot walking axis always maintain a precise position during long-term operation through a precise transmission and guiding mechanism, effectively avoiding operational instability caused by loose installation or displacement.

[0018] 2. This easy-to-install robot walking axis effectively enhances installation stability through a dual anti-slip and precise guiding structure. The rubber pads on the opposite side of the positioning plate are densely covered with anti-slip textures, forming a double anti-slip system with the anti-slip pads at the bottom of the walking axis mounting base. This increases friction when fixing robot components, preventing components from loosening or shifting during operation. At the same time, the clearance fit design between the connecting block and the connecting rod provides precise guidance for the movement of the positioning plate, reducing positioning accuracy errors and ensuring the smooth operation of the robot walking axis.

[0019] 3. This easy-to-install robot walking axis, through the shock-absorbing structure of the shock-absorbing pad and the supporting ring, greatly improves the shock absorption performance of the equipment. The shock absorbers at the four corners of the shock-absorbing pad and the sliding sleeve structure of the supporting ring and supporting disc at the center work together to effectively absorb the vibration generated during the operation of the robot, reduce the impact of vibration on surrounding equipment and the environment, extend the service life of the walking axis and the robot as a whole, and reduce the frequency of equipment maintenance caused by vibration.

[0025] 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.

[0026] Please see Figure 1 - Figure 4 This utility model provides a technical solution: a robot walking axis that is easy to install, including a walking axis mounting base 1, a positioning motor 2 installed on one side inside the walking axis mounting base 1, and a double-sided lead screw 3 fixedly connected to the transmission end of the positioning motor 2.

[0027] The end of the double-sided lead screw 3 away from the positioning motor 2 is connected to the inner wall of the traveling shaft mounting seat 1 through a bearing. The outer surface of the double-sided lead screw 3 is symmetrically connected to two moving blocks 4 through threads. A positioning plate 5 is fixedly connected to one side of the moving block 4.

[0028] When using this easy-to-install robot walking axis, start the positioning motor 2, and the double-sided lead screw 3 begins to rotate. Since the threads at both ends of the lead screw turn in opposite directions, the two moving blocks 4 move synchronously towards or away from each other under the drive of the threaded pair, which drives the positioning plate 5 to quickly adjust the spacing to adapt to different specifications of robot bases. The threaded pair of the double-sided lead screw 3 and the moving block 4 has excellent static self-locking performance, and the preload can be maintained without additional locking after positioning.

[0029] A connecting block 6 is connected to the side of the positioning plate 5 away from the moving block 4. A connecting rod 7 is horizontally arranged inside the travel axle mounting base 1. The connecting block 6 is in clearance fit with the connecting rod 7 through a sliding sleeve hole. Rubber pads 8 are attached to the opposite surfaces of the two positioning plates 5. The surface of the rubber pads 8 is densely covered with anti-slip textures. An anti-slip pad 9 is attached to the bottom of the inside of the travel axle mounting base 1. A travel axle fixing base plate 10 is set below the travel axle mounting base 1. A shock-absorbing pad 11 is sandwiched between the travel axle mounting base 1 and the travel axle fixing base plate 10. 1. The four corners of the interior are provided with preset grooves 12. The preset grooves 12 are embedded with shock absorbers 13. The two ends of the shock absorbers 13 are fixed to the bottom surface of the travel axle mounting base 1 and the upper surface of the travel axle fixing base plate 10, respectively. The center of the shock absorber pad 11 is provided with a center groove 14. The upper surface of the travel axle fixing base plate 10 is provided with a support ring 15 located inside the center groove 14. The middle of the bottom end of the travel axle mounting base 1 is connected to a support disc 16. The support disc 16 and the support ring 15 are connected by a clearance fit sliding sleeve method.

[0030] The positioning plate 5 slides with the connecting rod 7, which is laterally positioned inside the walking axis mounting base 1, through the connecting block 6, forming a stable guiding structure. This ensures that the positioning plates 5 on both sides always maintain parallel movement and avoids deviation. When the robot base is placed on the anti-slip pad 9 at the bottom of the walking axis mounting base 1, as the positioning plates 5 gradually approach, the rubber pads 8 attached to their opposite surfaces come into play. The densely distributed anti-slip texture on the surface works in conjunction with the anti-slip pad 9 to increase friction and firmly clamp the robot base. During robot operation, if vibration occurs, the shock absorption system between the walking axis mounting base 1 and the walking axis fixed base plate 10 will function to reduce vibration. The shock absorbers 13 embedded in the four pre-set grooves 12 inside the shock absorber 11 can effectively absorb vertical vibration energy. The central groove 14 at the center of the shock absorber 11 cooperates with the support ring 15 on the base plate 10 of the travel axle and the support disc 16 at the bottom of the travel axle mounting seat 1, allowing the travel axle mounting seat 1 to have a certain elastic displacement space in the horizontal direction, effectively buffering lateral impact force, and ensuring the stability of the center position of the travel axle mounting seat 1. In addition, the clearance fit between the connecting rod 7 and the connecting block 6 ensures smooth sliding and provides sufficient torsional stiffness, further improving the stability of the overall structure.

[0031] Working Principle: When using this easy-to-install robot walking axis, the positioning motor 2 is started, and the double-sided lead screw 3 begins to rotate. Because the threads at both ends of the lead screw rotate in opposite directions, the two moving blocks 4 move synchronously towards or away from each other under the drive of the threaded pair, causing the positioning plates 5 to quickly adjust their spacing to adapt to different robot base specifications. During this process, the positioning plates 5 slide against the connecting rod 7, which is laterally located inside the walking axis mounting base 1, through the connecting block 6, forming a stable guiding structure to ensure that the two positioning plates 5 always maintain parallel movement and avoid deviation. When the robot base is placed on the anti-slip pad 9 at the bottom of the walking axis mounting base 1, as the positioning plates 5 gradually approach, the rubber pads 8 attached to their opposite surfaces come into play. The densely distributed anti-slip textures on the surface work in conjunction with the anti-slip pads 9 to increase friction and firmly clamp the robot base. Simultaneously, the threads of the double-sided lead screw 3 and the moving blocks 4... The textured joint has excellent static self-locking performance. After positioning, it can maintain the preload without additional locking. During robot operation, if vibration occurs, the shock absorption system between the walking axis mounting base 1 and the walking axis fixed base plate 10 will play a role. The shock absorbers 13 embedded in the four corner grooves 12 inside the shock absorption pad 11 can effectively absorb the vertical vibration energy. The central groove 14 at the center of the shock absorption pad 11 cooperates with the support ring 15 on the walking axis fixed base plate 10 and the support disc 16 at the bottom of the walking axis mounting base 1, allowing the walking axis mounting base 1 to have a certain elastic displacement space in the horizontal direction, effectively buffering the lateral impact force, while ensuring the stability of the center position of the walking axis mounting base 1. In addition, the clearance fit between the connecting rod 7 and the connecting block 6 can provide sufficient torsional stiffness while ensuring smooth sliding, further improving the stability of the overall structure.

Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
