DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1 , 2As shown, a CMT welding heat dissipation structure described in an embodiment of the utility model comprises a CMT body 1; a slide cylinder 11 is fixedly connected to the side wall of the CMT body 1; a slide rod 12 is slidably connected to the inner side wall of the slide cylinder 11; a drive motor 13 is hingedly connected to the side wall of the slide rod 12; a fan blade 14 is fixedly connected to the output end of the drive motor 13; a servo motor 15 is fixedly connected to the side wall of the CMT body 1; a screw 16 is fixedly connected to the output end of the servo motor 15; a connecting block 17 is threadedly connected to the side wall of the screw 16; the connecting block 17 is fixedly connected to the slide rod 12; when in use, when the workpiece is welded by the CMT body 1, the drive motor 13 is started, and the drive motor 13 drives the fan blade 14 to rotate, and the rotation of the fan blade 14 generates a certain airflow to blow air to dissipate heat to the workpiece after welding. At the same time, when the fan blade 14 needs to be used, it can be started The servo motor 15 is driven, and the screw 16 is driven to rotate by the servo motor 15. As the screw 16 rotates, the connecting block 17 can be lifted and lowered on the side wall of the screw 16. While the connecting block 17 is lifted and lowered, the slide bar 12 slides on the inner wall of the driving motor 13 to maintain the smooth movement of the connecting block 17. The staff can hold the driving motor 13 to apply a certain force. Under the action of the hinge between the driving motor 13 and the slide bar 12, the blowing angle of the fan blade 14 is adjusted. In this process, the heat on the surface of the workpiece after the CMT body 1 is welded to the workpiece can be reduced, which makes it difficult to dissipate heat quickly, thereby affecting the processing speed of the workpiece. At this time, the fan blade 14 is used to blow air to the surface of the workpiece, thereby improving the heat dissipation effect after the workpiece is welded. At the same time, the height of the fan blade 14 can be adjusted by the screw 16.

[0024] like Figure 1 , 2As shown in , 4, the end of the screw 16 is fixedly connected to the guide block 2; the side wall of the guide block 2 is fixedly connected to the hopper 22; the side wall of the CMT body 1 is fixedly connected to the hopper 22; the inner wall of the hopper 22 is slidably connected to the ball 23; when in use, a certain amount of lubricating oil is first injected into the hopper 22, and when the screw 16 rotates, the convex block 21 rotates, and when the convex block 21 rotates to the position of the ball 23, the ball 23 is squeezed and squeezed into the hopper 22. At this time, the lubricating oil in the hopper 22 will flow out through the gap between the ball 23 and the hopper 22, so that it flows to the side wall of the guide block 2, Then it flows along the wall of the guide block 2 to between the screw 16 and the connecting block 17, thereby lubricating it. When the protrusion 21 and the sphere 23 are offset, under the action of the gravity of the sphere 23, the sphere 23 will block the hole of the hopper 22 to prevent the lubricating oil from flowing out to the outside. In this process, the rust of the screw 16 after long-term use can be reduced, which makes it difficult for the connecting block 17 to move on the side wall of the screw 16, thereby causing a certain impact on the height adjustment effect of the fan blade 14. At this time, the lubricating oil in the hopper 22 flows to between the screw 16 and the connecting block 17, thereby playing a lubricating role between the screw 16 and the connecting block 17.

[0025] like Figure 2 , 3 As shown, a pair of guide plates 3 are fixedly connected to the side wall of the slide cylinder 11; the guide plates 3 are symmetrically arranged on both sides of the slide cylinder 11 and have the same structure; the side wall of the guide plate 3 is fixedly connected to the bracket 31; the side wall of the bracket 31 is evenly fixedly connected to a plurality of cleaning brushes 32; when in use, when the slide bar 12 slides on the inner wall of the slide cylinder 11, the side wall of the slide bar 12 will contact the cleaning brush 32, and the dust and impurities attached to the surface of the slide bar 12 can be swept away by the cleaning brush 32, and the swept away dust and impurities will fall on the side wall of the guide plate 3, and then slide along the side wall of the guide plate 3 The guide plate 3 and the cleaning brush 32 are provided to clean the dust and impurities attached to the side walls of the slide bar 12, and the guide plate 3 can guide the dust and impurities that have been cleaned.

[0026] like Figure 2As shown, the side wall of the driving motor 13 is rotatably connected to the rotating shaft 4; the side wall of the rotating shaft 4 is evenly fixed with a plurality of blades 41; when in use, the airflow generated by the rotation of the fan blades 14 will contact the blades 41, and the rotating shaft 4 will be driven to rotate under the impact force of the airflow. At this time, the airflow can be broken up by the blades 41 to increase the blowing range of the airflow. In this process, the airflow blown out when the fan blades 14 rotate can be reduced and concentrated, resulting in a smaller blowing area, which affects the heat dissipation speed of the workpiece. At this time, the airflow is broken up by the rotation of the blades 41, thereby increasing the blowing range of the airflow and improving the heat dissipation speed of the workpiece.

[0027] like Figure 4 As shown, the side wall of the hopper 22 is hinged with a filter screen plate 5; the side wall of the filter screen plate 5 is fixedly connected with an elastic ball 51; the side wall of the hopper 22 is fixedly connected with a mounting block 52; the elastic ball 51 corresponds to the mounting block 52 in position; when in use, the staff holds the filter screen plate 5 and covers the filter screen plate 5 above the hopper 22. When the elastic ball 51 contacts the mounting block 52, a certain pressure is applied to the filter screen plate 5. At this time, the elastic ball 51 is squeezed and shrinks. When the elastic ball 51 is pressed into the groove of the mounting block 52, the elastic force of the elastic ball 51 The filter screen 5 will automatically recover and get stuck, thus fixing the filter screen 5. At this time, the filter screen 5 can prevent external dust and impurities from entering the hopper 22. At the same time, the staff can see the lubricating oil reserve in the hopper 22 through the filter screen 5. In this process, it is inconvenient to protect the hopper 22 during use, which makes it easy for external dust and impurities to fall into the hopper 22 and mix with the lubricating oil, thereby affecting the use effect of the lubricating oil. At this time, the filter screen 5 is set to prevent the hopper 22 from dust when in use.

[0028] like Figure 4 As shown, the side wall of the filter screen plate 5 is fixedly connected to the first magnetic block 6; the side wall of the hopper 22 is fixedly connected to the second magnetic block 61; the first magnetic block 6 and the second magnetic block 61 are magnetically connected; when in use, when the elastic ball 51 is pulled out of the groove of the mounting block 52 and the filter screen plate 5 is opened, the first magnetic block 6 will gradually approach the second magnetic block 61, and the two will have an attraction effect, pulling the first magnetic block 6 to the side wall of the second magnetic block 61, and the first magnetic block 6 will generate a certain impact force on the second magnetic block 61, through the first magnetic The collision of the first magnetic block 6 and the second magnetic block 61 can make the filter plate 5 vibrate, and the dust and impurities attached to the side wall of the filter plate 5 can be vibrated off under the action of vibration. In this process, the filter plate 5 can be reduced after long-term use, resulting in a lot of dust and impurities attached to the side wall of the filter plate 5, which is inconvenient to clean, thereby affecting the use effect of the filter plate 5. At this time, the vibration effect generated by the attraction between the first magnetic block 6 and the second magnetic block 61 can clean the dust and impurities attached to the side wall of the filter plate 5.

[0029] like Figure 3 As shown, the side wall of the cleaning brush 32 is fixedly connected with a connecting rod 7; the connecting rod 7 passes through the wall of the cleaning brush 32 and is fixedly connected thereto; when in use, when the cleaning brush 32 is cleaning, multiple cleaning brushes 32 can be fixedly connected by the connecting rod 7 so that they are concentrated together when cleaning. In this process, the cleaning brush 32 can be reduced to be relatively scattered when cleaning, resulting in poor cleaning effect of the cleaning brush 32 on the side wall of the sliding rod 12, thereby affecting the sliding effect between the sliding rod 12 and the sliding cylinder 11. At this time, the connecting rod 7 is set to increase the concentration of the cleaning brush 32 when cleaning, thereby improving the cleaning effect.

[0030] During operation, after the workpiece is welded by the CMT body 1, the drive motor 13 is started, and the drive motor 13 drives the fan blade 14 to rotate. The rotation of the fan blade 14 generates a certain amount of airflow to blow and dissipate heat to the workpiece after welding. At the same time, when the fan blade 14 needs to be used, the servo motor 15 can be started, and the servo motor 15 drives the screw 16 to rotate. As the screw 16 rotates, the connecting block 17 can be lifted and lowered on the side wall of the screw 16. When the connecting block 17 is lifted and lowered, the slide bar 12 slides on the inner wall of the drive motor 13 to maintain the smooth movement of the connecting block 17. The staff can hold the drive motor 13 to apply a certain force, and the fan blade 1 is hinged to the drive motor 13 and the slide bar 12. 4 is used to adjust the blowing angle. When in use, a certain amount of lubricating oil is first injected into the hopper 22. When the screw 16 rotates, the protrusion 21 rotates. When the protrusion 21 rotates to the position of the ball 23, the ball 23 is squeezed and squeezed into the hopper 22. At this time, the lubricating oil in the hopper 22 will flow out through the gap between the ball 23 and the hopper 22, so that it flows to the side wall of the guide block 2, and then flows along the wall of the guide block 2 to between the screw 16 and the connecting block 17, so as to lubricate it. When the protrusion 21 and the ball 23 are staggered, under the action of the gravity of the ball 23, the ball 23 will block the hole of the hopper 22 to prevent the lubricating oil from flowing out to the outside. When in use, when the slide bar 12 is on the inner wall of the slide cylinder 11 During the sliding process, the side wall of the slide bar 12 will contact the cleaning brush 32, and the dust and impurities attached to the surface of the slide bar 12 can be swept away by the cleaning brush 32. The swept away dust and impurities will fall on the side wall of the guide plate 3, and then slide down to the outside along the side wall of the guide plate 3. At the same time, through the full contact between the guide plate 3 and the side wall of the slide bar 12, the relatively firm impurities attached to the side wall of the slide bar 12 can be scraped off. When in use, the airflow generated by the rotation of the fan blades 14 will contact the blades 41, and the impact force of the airflow will drive the rotating shaft 4 to rotate. At this time, the airflow can be dispersed by the blades 41 to increase the blowing range of the airflow. When in use, the staff holds the filter screen plate 5 and covers the filter screen plate 5 above the hopper 22. When the elastic ball 51 contacts the mounting block 52 When the filter screen plate 5 is in use, a certain pressure is applied to the filter screen plate 5. At this time, the elastic ball 51 is squeezed and shrinks. When the elastic ball 51 is pressed into the groove of the mounting block 52, it will automatically recover under the elastic force of the elastic ball 51, making it stuck, and the filter screen plate 5 is fixed. At this time, the filter screen plate 5 can prevent external dust and impurities from entering the hopper 22. At the same time, the staff can see the lubricating oil reserve in the hopper 22 through the filter screen plate 5. When in use, when the elastic ball 51 is pulled out of the groove of the mounting block 52 and the filter screen plate 5 is opened, the first magnetic block 6 will gradually approach the second magnetic block 61, and the two will have an attraction effect, pulling the first magnetic block 6 to the side wall of the second magnetic block 61. At this time, the first magnetic block 6 will generate a certain impact force on the second magnetic block 61.The first magnetic block 6 hits the second magnetic block 61 to make the filter plate 5 vibrate, and the dust and impurities attached to the side wall of the filter plate 5 can be shaken off by the vibration. When the cleaning brush 32 is cleaning, the connecting rod 7 can be used to fix and connect multiple cleaning brushes 32 so that they are concentrated together when cleaning.
