Abstract

This patent discloses a welding frame that is easy to disassemble and assemble, comprising at least two welding frames that are assembled and connected together. Each welding frame includes a first U-shaped plate, a second U-shaped plate, two connecting plates, two connecting slots, four connecting holes, and four connecting rods. The two connecting plates are respectively installed on both sides of the second U-shaped plate, and the two connecting slots are respectively opened on both sides of the first U-shaped plate. Each connecting plate is inserted into one connecting slot. During assembly, the connecting rods on the upper first U-shaped plate and the second U-shaped plate are inserted into the connecting holes on the lower first U-shaped plate and the second U-shaped plate, and the assembly is based on the welding height of the welding robot. Conversely, disassembly is convenient. During disassembly and storage, the connecting plates on the second U-shaped plate can be inserted into the connecting slots on the first U-shaped plate, reducing the size of the welding frame for easy storage and avoiding the need for large storage space.

Description

Technical Field

[0001] This patent relates to the field of welding frame technology, specifically a welding frame that is easy to disassemble and assemble. Background Technology

[0002] In mechanical manufacturing, some welding projects with high precision requirements and large workloads are inefficient and produce inconsistent weld quality using conventional manual welding methods. Introducing industrial welding robots can effectively replace manual welding. Welding robots can work continuously as long as welding parameters and movement trajectories are provided, and external conditions such as water, electricity, and gas are ensured. They offer high efficiency and stable weld quality. Therefore, welding robots have advantages such as short response time, rapid action, and speed far exceeding manual welding. However, because the welding position is variable, a welding frame needs to be assembled during the welding process, and the welding robot is mounted on the frame for welding. Currently, welding frames are assembled, and the dimensions of each section are fixed, making it difficult to shrink and reduce their size, resulting in space constraints after disassembly and storage.

[0009] The technical solutions of this patent embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this patent, and not all of them. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0010] Please refer to Figures 1-4. This patent provides a technical solution: a welding frame that is easy to disassemble and assemble, including a welding frame 1, the number of welding frames 1 being no less than two, and the welding frames 1 being assembled and connected to each other; each welding frame 1 includes a first U-shaped plate 7, a second U-shaped plate 8, two connecting plates 9, two connecting grooves 10, four connecting holes 3, and four connecting rods 5; the two connecting plates 9 are respectively installed on both sides of the second U-shaped plate 8, the two connecting grooves 10 are respectively opened on both sides of the first U-shaped plate 7, each connecting plate 9 is inserted into one connecting groove 10, the two connecting holes 3 are opened on both sides of one end of the first U-shaped plate 7, and the other two connecting holes 3 are opened on both sides of one end of the second U-shaped plate 8, the two connecting rods 5 are opened on both sides of the other end of the first U-shaped plate 7, and the other two connecting rods 5 are opened on both sides of the other end of the second U-shaped plate 8. During assembly, the connecting rods 5 on the upper first U-shaped plate 7 and the second U-shaped plate 8 are inserted into the lower first U-shaped plate 7 and the second U-shaped plate 8. The welding frame 1 can be assembled according to the welding height of the welding robot by connecting the holes 3 on the U-shaped plate 8, and disassembly is convenient if the welding height is not large enough. During disassembly and storage, the connecting plate 9 on the second U-shaped plate 8 can be inserted into the connecting groove 10 on the first U-shaped plate 7, so that the size of the welding frame 1 can be reduced and stored easily. A ladder 2 is installed in the first U-shaped plate 7. The ladder 2 is set in correspondence with the first U-shaped plate 7. The ladder 2 includes a U-shaped frame 11 and a crossbar 12. The U-shaped frame 11 is installed in the first U-shaped plate 7, and the crossbar 12 is installed in the U-shaped frame 11. There are no less than five crossbars 12. The crossbars 12 are evenly distributed in the U-shaped frame 11. When installing the welding robot, the operator can step on the crossbars 12 on the U-shaped frame 11 to climb up and install it. A limiting structure 4 is installed on the first U-shaped plate 7. The limiting structure 4 is distributed on both sides of the first U-shaped plate 7. The limiting structure 4 includes a threaded hole 401 and a threaded rod 402. The threaded hole 401 is opened on the connecting groove 10. The threaded rod 402 is sleeved in the threaded hole 401 and abuts against the connecting plate 9. When the welding frame 1 is assembled and in use, the threaded rod 402 can be rotated and screwed into the threaded hole 401 and abutted against the connecting plate 9 to stabilize the first U-shaped plate 7 and the second U-shaped plate 8.A rubber sleeve 6 is installed on the outside of the connecting rod 5. The rubber sleeve 6 is set correspondingly to the connecting rod 5. When the connecting rod 5 is inserted into the connecting hole 3, the rubber sleeve 6 is also inserted into the connecting hole 3. The rubber sleeve 6 increases the friction between the connecting rod 5 and the connecting hole 3, so that the connection between the welding frames 1 is stable (the length of the connecting rod 5 is more than half the height of the connecting frame 1, and when inserted into the connecting hole 3, it can make the connection between the welding frames 1 stable). The connecting rod 5 is mounted on the first U-shaped plate 7 via the connecting structure 16, and also on the second U-shaped plate 8 via the connecting structure 16. The connecting structure 16 includes a threaded groove 17 and bolts 18. The threaded groove 17 is formed on the connecting rod 5 and is correspondingly arranged to the connecting rod 5. Bolts 18 are respectively installed on both sides of the first U-shaped plate 7 and on both sides of the second U-shaped plate 8. The threaded groove 17 on the connecting rod 5 is screwed onto the bolts 18 on the welding frame 1, so that the connecting rod 5 is mounted on the welding frame 1. A handle 13 is installed on the threaded rod 402 and is correspondingly arranged to the threaded rod 402. Eight arc-shaped grooves 14 are equidistantly formed on the handle 13. Rotating the handle 13 rotates the threaded rod 402, and the arc-shaped grooves 14 increase the friction between the hand and the handle 13. The second U-shaped plate 8 has mounting holes, through which an external welding robot can be mounted. The mounting holes are set to correspond to the second U-shaped plate 8.

[0011] When using this easy-to-disassemble and assemble welding frame, firstly, manually screw the threaded groove 17 on the connecting rod 5 onto the bolt 18 on the welding frame 1, so that the connecting rod 5 is installed on the welding frame 1. During assembly, insert the connecting rod 5 on the upper first U-shaped plate 7 and the second U-shaped plate 8 into the connecting hole 3 on the lower first U-shaped plate 7 and the second U-shaped plate 8. When the connecting rod 5 is inserted into the connecting hole 3, the rubber sleeve 6 is inserted into the connecting hole 3. The rubber sleeve 6 increases the friction between the connecting rod 5 and the connecting hole 3, making the connection between the welding frames 1 stable. The operator can step on the crossbar 12 on the U-shaped frame 11 to climb and secure the frame. Assemble according to the welding height of the welding robot. An external welding robot can be installed on the second U-shaped plate 8 through the mounting hole, and then the welding work can be completed. Conversely, it is easy to disassemble. During disassembly and storage, loosen the threaded rod, so that the connecting plate 9 on the second U-shaped plate 8 can be inserted into the first U-shaped plate 7. The connecting groove 10 on the upper part reduces the size of the welding frame 1, making it easier to store.
