Description

Technical Field

[0001] This utility model belongs to the field of industrial robot technology, specifically relating to a base for industrial robots. Background Technology

[0002] In today's highly automated industrial production, industrial robots have become indispensable and important equipment. They are widely used in many industries such as automobile manufacturing, electronic equipment production, and machining, and can perform a variety of high-precision, highly repetitive, and complex tasks such as welding, handling, assembly, and painting, thereby significantly improving production efficiency, reducing labor costs, and ensuring product quality consistency.

[0003] However, in the actual operation of industrial robots, the frequency and complexity of their movements, as well as the strong vibrations they generate during operation, pose a serious challenge to the installation and fixing methods of the robots.

[0004] Traditional industrial robot installation methods typically rely solely on bolts to secure the robot body to a base plate, which is then bolted to the ground. However, this seemingly simple and direct method has several hidden dangers. During prolonged, high-intensity operation, the continuous vibrations of the industrial robot exert constant impact and friction on the bolted connections. This repeated action gradually weakens the bolt's tightening force, causing it to loosen.

[0005] Moreover, industrial production environments are often complex and variable. Significant temperature fluctuations can cause materials to expand and contract with temperature changes, thus altering the preload of bolt connections; changes in humidity can trigger corrosion of metal components, affecting the connection strength of bolts. In addition, contaminants such as dust and oil in the production site can also penetrate the bolt connections, further compromising their fastening effect.

[0006] If bolts become loose, it will first and foremost affect the working precision and accuracy of industrial robots. Precisely programmed motion trajectories may deviate, resulting in products that do not meet quality standards and increasing the defect rate. Secondly, loose bolts will significantly reduce the robot's stability, potentially causing it to shake or even tip over during operation. This can damage expensive robotic equipment and cause serious personal injury to nearby workers. Furthermore, frequent bolt loosening requires substantial time and manpower for maintenance and retightening, leading to production downtime and severely impacting production schedules and efficiency.

[0007] To address this, we propose a base for industrial robots that reduces the risk of bolt loosening due to robot vibration during operation, thereby significantly improving the stability and reliability of the robot during operation. Utility Model Content

[0008] The purpose of this invention is to provide a base for an industrial robot that reduces the risk of bolt loosening caused by robot vibration during operation, thereby greatly improving the stability and reliability of the robot during operation.

[0009] The specific technical solution adopted by this utility model is as follows:

[0010] An industrial robot base includes a base plate and a robot body. The base plate is fixed to the ground by four first fixing bolts. Each first fixing bolt has a first limiting hole. The base plate has four sliding grooves, one circular groove, and four threaded holes. The four sliding grooves communicate with the one circular groove. Each sliding groove has a moving component inside. The moving component has a gear, a first limiting rod, and a second limiting rod. The first limiting rod matches the first limiting hole. The circular groove has a rotating ring inside. The bottom of the rotating ring has meshing teeth that mesh with the gear.

[0011] The robot body has a mounting plate at its bottom, and four second fixing bolts are provided on the mounting plate. The second fixing bolts are connected to the threaded holes, and each second fixing bolt has a second limiting hole that matches the second limiting rod.

[0012] Furthermore, the moving component includes a rotating rod disposed inside the slide groove. The rotating rod is provided with the gear and opposite threads. The opposite threads are respectively provided with a first threaded sleeve and a second threaded sleeve. The top of the first threaded sleeve is connected to the first limiting rod, and the top of the second threaded sleeve is connected to the second limiting rod.

[0013] Furthermore, the circular groove matches the rotating ring.

[0014] Furthermore, the position of the groove corresponds to the positions of the first fixing bolt and the second fixing bolt.

[0015] Furthermore, a buffer layer is provided on the outer side of the rotating ring.

[0016] Furthermore, a fixing block is provided on the base plate, and a through hole is provided on the fixing block. A movable rod is movably arranged inside the through hole. A limit plate is installed at one end of the movable rod, and a locking block is installed at the other end of the movable rod. A spring is sleeved on the movable rod, and the spring is located between the limit plate and the fixing block. Locking holes are arranged on the outer side of the rotating ring, and the locking holes match the locking blocks.

[0017] The technical effects achieved by this utility model are as follows:

[0018] First, the base plate is fixed to the ground using the first fixing bolt. Then, the robot body is mounted on the base plate using the second fixing bolt. Next, a rotating ring rotates inside a circular groove. The meshing teeth on the rotating ring drive the gear to rotate, which in turn drives the moving component to work, thereby driving the first and second limit rods to move in opposite directions. Then, the first limit rod enters the first limit hole, and the second limit rod enters the second limit hole. This prevents the first and second fixing bolts from loosening due to vibrations generated by the robot body during operation, ensuring the stability of the robot body. This device can reduce the risk of bolt loosening caused by robot vibrations during operation, greatly improving the stability and reliability of the robot during operation.

[0025] To make the purpose and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0026] like Figure 1-4As shown, the technical solution adopted by this utility model is as follows: A base for an industrial robot includes a base plate 1 and a robot body 2. The base plate 1 is fixed to the ground by four first fixing bolts 3. Each first fixing bolt 3 is provided with a first limiting hole. The base plate 1 is provided with four sliding grooves 4, a circular groove 5 and four threaded holes 6. The four sliding grooves 4 are connected to the circular groove 5. Each sliding groove 4 is provided with a moving component. The moving component is provided with a gear 7, a first limiting rod 8 and a second limiting rod 9. The first limiting rod 8 matches the first limiting hole. The circular groove 5 is provided with a rotating ring 10. The bottom of the rotating ring 10 is provided with meshing teeth 11 that mesh with the gear 7.

[0027] The robot body 2 has a mounting plate 12 at its bottom. The mounting plate 12 has four second fixing bolts 13. The second fixing bolts 13 are connected to the threaded holes 6, and each second fixing bolt 13 has a second limiting hole that matches the second limiting rod 9.

[0028] The movable component includes a rotating rod 14 disposed inside the slide 4. The rotating rod 14 is provided with a gear 7 and opposite threads. The opposite threads are respectively provided with a first threaded sleeve 15 and a second threaded sleeve 16. The top of the first threaded sleeve 15 is connected to the first limiting rod 8, and the top of the second threaded sleeve 16 is connected to the second limiting rod 9.

[0029] When gear 7 rotates, it drives rotating rod 14 to rotate inside slide groove 4. When rotating rod 14 rotates, due to the opposite threads, the first threaded sleeve 15 and the second threaded sleeve 16 move relative to each other or in opposite directions, thereby causing the first limiting rod 8 to enter the first limiting hole and the second limiting rod 9 to enter the second limiting hole for locking.

[0030] The circular groove 5 is matched with the rotating ring 10. This arrangement allows the rotating ring 10 to drive the meshing teeth 11 to rotate inside the circular groove 5 without causing jamming.

[0031] The mounting plate 12 and the robot body 2 are welded together, so they can be considered as one piece. Therefore, they can be installed directly. In the prior art, the mounting plate 12 and the robot body 2 are all one piece, so we will not go into too much detail here.

[0032] The position of the slide groove 4 corresponds to the position of the first fixing bolt 3 and the second fixing bolt 13. That is to say, if the slide groove 4 is provided between the position where the first fixing bolt 3 is fixed and the position where the second fixing bolt 13 is fixed, this arrangement can facilitate the fixing of the first limiting rod 8 and the second limiting rod 9.

[0033] The rotating ring 10 has a buffer layer on its outer side, which is made of rubber to reduce the impact force from the outside.

[0034] A fixing block 17 is provided on the base plate 1. A through hole is provided on the fixing block 17. A movable rod 18 is movably installed inside the through hole. A limit plate is installed at one end of the movable rod 18, and a locking block 19 is installed at the other end of the movable rod 18. A spring 20 is sleeved on the movable rod 18. The spring 20 is located between the limit plate and the fixing block 17. Locking holes 21 are arranged in an array on the outer side of the rotating ring 10. The locking holes 21 match the locking blocks 19. This arrangement allows the locking blocks 19 to enter the corresponding locking holes 21 for locking when the first fixing bolt 3 and the second fixing bolt 13 are fixed, thereby preventing the rotating ring 10 from shaking and moving.

[0035] It should be noted that one end of the spring 20 is connected to the limiting plate, and the other end is connected to the fixed block 17. This arrangement allows the spring 20 to be stretched, thereby allowing the movable rod 18 to move.

[0036] The working principle of this utility model is as follows: First, the base plate 1 is fixed to the ground by the first fixing bolt 3. Then, the robot body 2 is installed on the base plate 1 by the second fixing bolt 13. Then, the rotating ring 10 rotates inside the circular groove 5. The meshing teeth 11 on the rotating ring 10 drive the gear 7 to rotate. The gear 7 makes the moving component work, thereby driving the first limiting rod 8 and the second limiting rod 9 to move in opposite directions. Then, the first limiting rod 8 enters the first limiting hole and the second limiting rod 9 enters the second limiting hole, preventing the first fixing bolt 3 and the second fixing bolt 13 from loosening due to vibration generated by the robot body 2 during operation. This ensures the stability of the robot body 2. This device can reduce the risk of bolt loosening caused by robot working vibration and greatly improve the stability and reliability of the robot during operation.

[0037] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
