Description

Technical Field

[0001] This utility model belongs to the field of slide rail technology, specifically relating to a robot ground rail welding frame. Background Technology

[0002] In automated welding production lines, robots or robotic arms often play the role of welding, welding passing objects. Robots need to be equipped with multi-axis robotic arms and welding tools to weld workpieces, and most welding robots also need to slide within a certain range of motion to ensure that the welding robot remains relatively stationary with the workpieces on the production line during welding.

[0003] Please see Figure 3-4 During operation, the robot arm's center of gravity shifts. This shift causes the robot arm to rotate, and the vertical limiting structure bears the load. Prolonged use can lead to fatigue in this vertical limiting structure. Currently, guide rails or slides are primarily formed by one-piece stamping or welding. When the vertical limiting structure fatigues, the robot's center shift causes the base to exert force on the vertical limiting structure, leading to deformation. In such cases, the entire slide needs to be replaced. Utility Model Content

[0004] This utility model provides a robot ground rail welding frame, which adopts a split positioning structure and a new force decomposition method, increasing the convenience of replacement and the stability of use.

[0005] This utility model provides the following technical solution: including: A support rail base is used to support the robot's own weight. The support rail base includes a base and a support rail that are fixedly connected to each other. The support rail is fixed to the bearing surface by the base. The rollers of the robot's moving platform rotate on the top of the support rail. A limiting mechanism is used to limit the vertical movement of the rollers of a robot mobile platform. The limiting mechanism includes a T-shaped baffle and an L-shaped fixed seat that are fixedly connected to each other. The T-shaped baffle is fixedly connected to the bearing surface through the L-shaped fixed seat. The T-shaped baffle includes a vertical baffle and a force-relieving baffle. The vertical baffle is parallel to the upper surface of the support rail and forms a guide cavity for receiving the roller, and the force-relieving baffle is in contact with the outer wall of the support rail.

[0006] The base has several equally spaced relief grooves, and the L-shaped fixing seat is located at the center of the relief grooves.

[0007] The edge of the clearance groove has two opposing positioning slots, and the top of the L-shaped fixing seat has a centerline slot. The positioning slots and the centerline slots are connected to form a positioning groove.

[0008] The two adjacent T-shaped barrier plates are in contact with each other, and the color of the contact surface of the two adjacent T-shaped barrier plates is different from the color of the top surface of the T-shaped barrier plate.

[0009] The bottom surface of the force-relieving baffle is located below the top surface of the support rail.

[0010] The length of the T-shaped barrier plate is greater than the length of the L-shaped fixing base.

[0011] The beneficial effects of this utility model are: Advantage 1: When the robot experiences a center shift, it tilts forward, and the rollers exert a rotational force on the vertical baffle. The vertical baffle tends to flip, but the force-relieving baffle holds the support rail in place, applying a horizontal force to the support rail. The support rail itself has a certain length, a large welding area, and low stress between the support rail and the base under normal operating conditions. The force-relieving baffle applies a portion of the force from the vertical baffle to the support rail, increasing the stability of the baffle support. Another portion of the force is applied to the L-shaped fixing seat through the T-shaped baffle. Since the L-shaped fixing seat is independent of the base, if the local T-shaped baffle is damaged, only the L-shaped fixing seat needs to be removed and replaced.

[0012] Advantage II: Secondly, the force-relieving baffle also seals the end of the guide cavity. The two ends of the roller are inside the guide cavity and are limited by the force-relieving baffle. A convex groove is formed between the two guide cavities, which improves the accuracy of guidance.

[0013] Advantage III: Due to the setting of the force-relieving baffle, the part of the T-shaped baffle that is not supported by the L-shaped fixed seat can still resist the rotational force, thereby reducing the length of the fixed surface and enabling the L-shaped fixed seat and the base to be staggered and fixed.

[0014] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0016] Please see Figures 1-5 The present invention provides the following technical solution, including: The support rail base 1 is used to support the robot's own weight. The support rail base 1 includes a base 11 and a support rail 12 that are fixedly connected to each other. The support rail 12 is fixed to the bearing surface through the base 11, and the rollers of the robot's moving platform rotate on the top of the support rail 12. The limiting mechanism 2 is used to limit the vertical direction of the rollers of the robot mobile platform. The limiting mechanism 2 includes a T-shaped baffle 21 and an L-shaped fixed seat 22 that are fixedly connected to each other. The T-shaped baffle 21 is fixedly connected to the bearing surface through the L-shaped fixed seat 22. The T-shaped baffle 21 includes a vertical baffle 211 and a force-relieving baffle 212. The vertical baffle 211 is parallel to the upper surface of the support rail 12 and forms a guide cavity 3 for receiving the roller. The force-relieving baffle 212 contacts the outer wall of the support rail 12.

[0017] In this implementation plan: Please refer to Figures 2-5 The base 11 is fixed to the bearing surface, which can be the ground. The base 11 is fixed to the bearing surface by bolts. The support rail 12 is mainly for supporting the robot's own weight. The robot can slide on the top of the support rail 12 by any means such as traction, rack and pinion, gear transmission, or self-drive by the drive wheel. Since this technical solution only involves the frame structure, the dashed lines in the attached drawings represent the sliding seat and pulley; the specific traction structure is not shown.

[0018] When the robot experiences center offset, please refer to Figure 4When the robot tilts forward, the rollers exert a rotational force on the vertical baffle 211, causing it to tend to flip. However, the force-relieving baffle 212 holds the support rail 12 in place, applying a horizontal force to it. The support rail 12 has a certain length, a large welding area, and experiences low stress between it and the base 11 during normal operation. The force-relieving baffle 212 transfers a portion of the force from the vertical baffle 211 to the support rail 12, increasing its stability. Another portion of the force is applied to the L-shaped fixing seat 22 via the T-shaped baffle 21. Since the L-shaped fixing seat 22 is independent of the base 11, damage to the T-shaped baffle 21 only requires replacement of the L-shaped fixing seat 22.

[0019] Further technical benefits: The force-relieving baffle 212 also seals the end of the guide cavity 3. The two ends of the roller are inside the guide cavity 3 and are limited by the force-relieving baffle 212. A convex groove is thus formed between the two guide cavities 3, which improves the accuracy of guidance.

[0020] The base 11 has several equally spaced relief grooves 112, and the L-shaped fixing seat 22 is located at the center of the relief grooves 112.

[0021] The clearance groove 112 can accommodate the L-shaped fixing seat 22, allowing the L-shaped fixing seat 22 to be fixed in the bearing surface within the clearance groove 112, thereby enabling independent replacement.

[0022] Two opposing positioning slots 111 are provided on the edge of the relief groove 112, and a centerline slot 221 is provided on the top of the L-shaped fixing seat 22. The positioning slots 111 and the centerline slot 221 are connected to form a positioning groove.

[0023] Since the L-shaped fixing seat 22 is located in the relief groove 112, the spacing of the L-shaped fixing seat 22 needs to be fixed. After the positioning slot 111 and the center line slot 221 are aligned, it is only necessary to insert the square tube into the positioning slot 111 and the center line slot 221 to restrict the positional relationship between the L-shaped fixing seat 22 and the base 11, thereby ensuring that the positional relationship between the support rail 12 and the base 11 is fixed.

[0024] Two adjacent T-shaped baffles 21 are in contact with each other, and the color of the contact surface of the two adjacent T-shaped baffles 21 is different from the color of the top surface of the T-shaped baffle 21. Multiple T-shaped baffles 21 form a vertical limiting surface. When a local T-shaped baffle 21 deforms and is pushed up, the end face of the T-shaped baffle 21 is exposed. The usage status of the T-shaped baffle 21 can be quickly determined by the color difference, and it can be replaced accordingly.

[0025] The bottom surface of the force-relieving baffle 212 is located below the top surface of the support rail 12. When the bottom surface of the force-relieving baffle 212 is located below the top surface of the support rail 12, the force-relieving baffle 212 and the support rail 12 have a certain contact surface, so that the force-relieving baffle 212 can apply a horizontal force to the support rail 12.

[0026] The length of the T-shaped baffle 21 is greater than the length of the L-shaped fixing seat 22. Due to the setting of the force-relieving baffle 212, the part of the T-shaped baffle 21 that is not supported by the L-shaped fixing seat 22 can still resist the rotational force, thereby reducing the length of the fixing surface and enabling the L-shaped fixing seat 22 and the base 11 to be fixed in a staggered manner.
