[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Specific examples are given below.

[0026] See also Figure 1-Figure 3The utility model provides a robot welding tool that can change its angle, including a tool base 1; a pair of cylinder rotating shafts 11 are installed on the side walls of the tool base 1; the cylinder rotating shafts 11 are symmetrically arranged on both sides of the tool base 1 and have the same structure; a cylinder 12 is installed on the side wall of the cylinder rotating shaft 11; a cylinder tool connecting shaft 13 is installed on the side wall of the cylinder 12; a pair of tool rotating shafts 14 are symmetrically installed on the side wall of the tool base 1; the same tool table 15 is installed on the side wall of the tool rotating shaft 14; a cylinder telescopic rod 16 is installed on the side wall of the cylinder 12; when in use, after the compressed air is connected to the cylinder 12, the cylinder telescopic rod 16 will work to rotate the cylinder The rotating shaft 11 is the support point, and the cylinder 12 pushes the tooling table 15 upward, so that the tooling table 15 rotates around the position of the tooling rotating shaft 14. When the cylinder 12 has completed its stroke, the tooling can be rotated to the required position. In this process, the robot's limited welding angle can reduce the inconvenience of rotating the tooling, resulting in some welds being unable to complete automatic welding, and it is difficult to quickly load and unload the workpiece, resulting in a certain increase in workload. At this time, the cylinder 12 pushes the tooling table 15 to rotate, thereby playing a role in adjusting the rotation angle of the tooling table 15, improving the flexibility of the tooling table 15 during welding, and playing a role in the convenience of loading and unloading the workpiece, reducing the work intensity.

[0027] Further, such as Figure 1 , Figure 4 , Figure 5 As shown, a pair of slide rails 2 are fixedly connected to the side walls of the tooling base 1; the slide rails 2 are symmetrically arranged on both sides of the tooling base 1 and have the same structure; the inner side walls of the slide rails 2 are slidably connected to the mounting blocks 21; the side walls of the mounting blocks 21 are fixedly connected to the same collection box 22; when in use, the staff first holds the collection box 22, aligns the mounting blocks 21 with the slide rails 2, and inserts them into the slide rails 2. At this time, a certain friction force will be generated due to the full contact between the two, so that the collection box 22 can be installed. At this time, the welding slag generated during welding will fall into the collection box 22 and pass through the collection box 2 2 can collect welding slag. At the same time, when the tooling table 15 is rotated and tilted, the welding slag remaining on the workpiece and the side wall of the tooling table 15 will also fall into the collection box 22. When the collection box 22 collects enough, the mounting block 21 is taken out from the slide rail 2, and the welding slag in the collection box 22 can be processed. In this process, a certain amount of welding slag generated when welding the workpiece can be reduced, resulting in the welding slag falling around the tooling base 1, which is inconvenient to clean, thereby increasing a certain amount of workload. At this time, the collection box 22 is set to collect the welding slag generated when the workpiece is welded.

[0028] Further, such as Figure 4 , Figure 5As shown, the side wall of the mounting block 21 is symmetrically provided with a pair of slots 3; the side wall of the slide rail 2 is fixedly connected to a pair of brackets 31; the brackets 31 are symmetrically arranged on both sides of the slide rail 2 and have the same structure; the side wall of the bracket 31 is fixedly connected to a spring 32; the end of the spring 32 is fixedly connected to an insert block 33; the side wall of the insert block 33 is fixedly connected to a pull rod 34; the pull rod 34 passes through the wall of the bracket 31 and is slidably connected thereto; when in use, when the mounting block 21 is inserted into the slide rail 2, the mounting block 21 will squeeze the insert blocks 33 on both sides and stretch them to both sides, and then when the mounting block 21 is fully inserted into the slide rail 2, the insert blocks 33 will correspond to the position of the slots 3, and at this time, through the spring 32 Under the action of elastic force, the plug block 33 can be pushed and pushed into the side wall of the slot 3 to make it stuck, thereby fixing the mounting block 21. When the mounting block 21 needs to be disassembled, the staff can hold and pull the pull rod 34 to pull the plug block 33 out of the side wall of the slot 3, and then the mounting block 21 can be taken out of the slide rail 2. In this process, the poor fixing effect of the mounting block 21 in the slide rail 2 can be reduced, resulting in the installation block 21 easily sliding out of the slide rail 2 when the collection box 22 is accidentally pulled, causing the residue in the collection box 22 to spill out. At this time, the plug block 33 is stuck into the side wall of the slot 3, thereby increasing the fixing effect of the mounting block 21 in the slide rail 2 and improving the firmness of the collection box 22.

[0029] Further, such as Figure 4 , Figure 5 As shown, the side wall of the slide rail 2 is fixedly connected with a plurality of elastic plates 4; the elastic plates 4 are evenly distributed on the side wall of the slide rail 2 and have the same structure; the side wall of the elastic plate 4 is fixedly connected with a sponge block 41; when in use, when the mounting block 21 is inserted into the slide rail 2, the mounting block 21 will contact and squeeze the elastic plates 4 on both sides, and the elastic plates 4 can be deformed by squeezing them, and then the mounting block 21 can be pushed to the middle of the slide rail 2 under the elastic force of the elastic plates 4, and the mounting block 21 will also slide to the middle of the elastic plates 4 on both sides, and through the elastic action of the elastic plates 4 The sponge block 41 can be brought into full contact with the side wall of the mounting block 21, and the dust and impurities attached to the side wall of the mounting block 21 can be wiped off by the sponge block 41. In this process, it can reduce the difficulty of aligning the two when the staff inserts the mounting block 21 into the slide rail 2, making the insertion process more cumbersome. At this time, the elastic plate 4 is set to play a limiting role when the mounting block 21 is inserted into the slide rail 2, and the sponge block 41 can clean the dust and impurities attached to the side wall of the mounting block 21, thereby improving the smoothness of the sliding between the mounting block 21 and the slide rail 2.

[0030] Further, such as Figure 5As shown, a protrusion 5 is fixedly connected to the inner wall of the slide rail 2; an elastic block 51 is fixedly connected to the side wall of the mounting block 21; when in use, by inserting the mounting block 21 into the slide rail 2, the elastic block 51 will shrink due to the squeezing of the protrusion 5, and when the mounting block 21 is fully inserted into the slide rail 2, the two will be staggered with each other, and at this time, they will automatically recover under the elastic action of the elastic block 51, so that they are stuck to each other. In this process, the collection box 22 can be reduced in use, resulting in the installation block 21 being easily slipped out of the slide rail 2 when the pull rod 34 is accidentally pulled, thereby causing a certain impact on the fixing effect of the collection box 22. At this time, the protrusion 5 and the elastic block 51 are stuck to each other, thereby further increasing the fixing effect of the installation block 21 in the slide rail 2.

[0031] Further, such as Figure 1 , Figure 4 As shown, the side wall of the collection box 22 is fixedly connected with a guide plate 6; the side wall of the guide plate 6 is symmetrically fixedly connected with a pair of limit plates 61; when in use, when the workpiece is in the process of welding, part of the welding slag will fall on the side wall of the guide plate 6, and at this time, the welding slag will slide along the side wall of the guide plate 6, so that it slides into the collection box 22, and at the same time, the welding slag is blocked by the limit plates 61 on both sides, which can prevent the welding slag from sliding to both sides from the side wall of the guide plate 6. In this process, when the workpiece is welded, it can reduce the possibility that part of the welding slag will fall to the middle of the tooling base 1. At this time, the guide plate 6 can play a role in guiding the welding slag that falls to the middle of the tooling base 1, and the limit plate 61 can play a role in limiting the sliding of the welding slag.

[0032] Further, such as Figure 4 As shown, the inner wall of the collection box 22 is fixedly connected with a baffle 7; when in use, after the welding slag enters the collection box 22, if the collection box 22 shakes, the baffle 7 can prevent the welding slag from splashing out of the collection box 22. In this process, the accidental impact on the collection box 22 can be reduced, causing part of the welding slag in the collection box 22 to easily fall out of the collection box 22. At this time, the baffle 7 is set to protect the welding slag in the collection box 22.

[0033] Working principle: When in use, after the compressed air is connected through the cylinder 12, the cylinder telescopic rod 16 will work, with the cylinder rotating shaft 11 as the support point, the cylinder 12 pushes the tooling table 15 upward, so that the tooling table 15 rotates around the position of the tooling rotating shaft 14. When the cylinder 12 has completed its stroke, the tooling can be rotated to the required position. When in use, the staff will first hold the collection box 22, align the mounting block 21 with the slide rail 2, and insert it into the slide rail 2. At this time, a certain friction force will be generated due to the full contact between the two, so that the collection box 22 can be installed. At this time, the welding slag generated during welding will fall into the collection box 22, and the welding slag can be collected through the collection box 22. When the workbench 15 is rotated and tilted, the welding slag remaining on the workpiece and the side wall of the workbench 15 will also fall into the collection box 22. When the collection box 22 collects enough, the mounting block 21 is taken out from the slide rail 2, and the welding slag in the collection box 22 can be processed. When in use, when the mounting block 21 is inserted into the slide rail 2, the mounting block 21 will squeeze the plug blocks 33 on both sides and stretch them to both sides. Then, when the mounting block 21 is fully inserted into the slide rail 2, the plug block 33 will correspond to the position of the slot 3. At this time, the plug block 33 can be pushed by the elastic force of the spring 32 and pushed onto the side wall of the slot 3 to make it stuck, so that the mounting block 21 can be fixed. When disassembling, the staff can hold and pull the pull rod 34 to pull the insert block 33 out of the side wall of the slot 3, and then the mounting block 21 can be taken out from the slide rail 2. When in use, when the mounting block 21 is inserted into the slide rail 2, the mounting block 21 will contact and squeeze the elastic plates 4 on both sides, and the elastic plates 4 can be squeezed to cause a certain deformation. Then, under the elastic force of the elastic plates 4, the mounting block 21 can be pushed to the middle of the slide rail 2. At the same time, the mounting block 21 will also slide toward the middle of the elastic plates 4 on both sides, and the elastic action of the elastic plates 4 can make the sponge block 41 fully contact with the side wall of the mounting block 21, and the dust and impurities attached to the side wall of the mounting block 21 can be wiped off by the sponge block 41. When in use, When the mounting block 21 is inserted into the slide rail 2, the elastic block 51 will be squeezed by the protrusion 5 and will shrink. When the mounting block 21 is fully inserted into the slide rail 2, the two will be staggered with each other. At this time, they will automatically recover under the elastic action of the elastic block 51, so that they are stuck to each other. When in use, when the workpiece is in the process of welding, part of the welding slag will fall on the side wall of the guide plate 6. At this time, the welding slag will slide along the side wall of the guide plate 6 and slide into the collection box 22. At the same time, the welding slag is blocked by the limit plates 61 on both sides to prevent the welding slag from sliding off the side walls of the guide plate 6 to both sides. When in use, after the welding slag enters the collection box 22, if the collection box 22 shakes, the baffle 7 can prevent the welding slag from splashing out of the collection box 22.

[0034] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
