[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Please see Figures 1 to 5 This utility model provides a blowing device for processing automotive fasteners, including a nozzle body 1 and a connection port 9 connected to the bottom of the nozzle body 1. The connection port 9 is connected to an air connector 11 connected to the top of the air supply pipe 5. An annular sleeve 10 is fixed on the outside of the air connector 11. The annular sleeve 10 is connected to a connection mechanism for firmly connecting the connection port 9 and the air connector 11.
[0019] The gas supply pipe 5 is connected to the gas supply unit, which is existing technology, and is used to supply high-pressure gas to the nozzle body 1. The fastener is held by a robotic arm and positioned directly above the nozzle body 1. The robotic arm, also existing technology, gradually moves the fastener closer to the nozzle body 1 and stops at a certain distance. Then, it drives the fastener to rise again. Repeating this process twice cleans the impurity area 111 inside the fastener, replacing traditional manual operation and resulting in high processing efficiency.
[0020] The connecting mechanism includes a lifting sleeve 3, multiple connecting rods 12, multiple positioning blocks 13, and locking bolts 6. The lifting sleeve 3 is slidably connected to an annular sleeve 10, which guides the positioning blocks 13. The two ends of the connecting rods 12 are axially connected to the lifting sleeve 3 and the positioning blocks 13. The locking bolts 6 limit the movement of the lifting sleeve 3. The positioning blocks 13 are connected to the connection port 9. Typically, three positioning blocks 13 are provided, with an adjacent included angle of 120°. Correspondingly, three connecting rods 12 are also provided. When the connection port 9 is connected to the air connector 11, the lifting sleeve 3 is pushed down. The lifting sleeve 3 simultaneously applies a thrust to the three connecting rods 12, causing the connecting rods 12 to push the positioning blocks 13 forward, pressing them against the limiting groove 14 and applying downward pressure to the connection port 9. This improves the stability of the connection between the nozzle body 1 and the air connector 11, achieving rapid installation. Then, the locking bolts 6 are used to lock and fix the lifting sleeve 3, improving the stability of the connection between the positioning blocks 13 and the limiting groove 14. When the nozzle body 1 needs to be disassembled, the adjusting locking bolt 6 is loosened to the lifting sleeve 3, and then the lifting sleeve 3 is pushed up. The lifting sleeve 3 applies a pulling force to the three connecting rods 12 simultaneously. The connecting rods 12 pull the positioning block 13 back, so that the positioning block 13 is separated from the limiting groove 14, thereby loosening the nozzle body 1. The operation is simple and convenient, making it easy to replace the nozzle body 1 and meet the requirements of fastener purging of different sizes.
[0021] The positioning block 13 is slidably connected to the annular sleeve 10, which improves the stability of the reciprocating movement of the positioning block 13.
[0022] Multiple limiting grooves 14 are provided on the outside of the connection port 9, and the positioning block 13 matches the limiting grooves 14.
[0023] The locking bolt 6 is threadedly connected to the lifting sleeve 3, and the end of the locking bolt 6 matches the connecting groove located on the outside of the annular sleeve 10. The locking bolt 6 can be moved by rotating it, which facilitates connection or separation from the connecting groove.
[0024] The inner side of the air connector 11 is provided with a sealing surface 16, and the top of the air connector 11 is connected with a sealing gasket 15. The connection port 9 is pressed against the sealing surface 16 and the sealing gasket 15. When the nozzle body 1 is installed, the sealing gasket 15 and the sealing surface 16 can improve the sealing performance of the connection port 9 and the air connector 11, achieving a double sealing effect and preventing gas leakage.
[0025] Multiple L-shaped rods 8 are connected to the outer side of the nozzle body 1, and the L-shaped rods 8 are connected to the annular sleeve 10. There are three L-shaped rods 8, with adjacent rods forming an included angle of 120°, and the L-shaped rods 8 are aligned with the limiting groove 14. During installation of the nozzle body 1, the connecting port 9 is inserted into the air connector 11, connecting the L-shaped rods 8 with the limiting groove 14, thus initially limiting the nozzle body 1. At this time, the positioning block 13 is aligned with the limiting groove 14, facilitating subsequent docking. Furthermore, the ends of the limiting groove 14 are rounded to allow the positioning block 13 to smoothly insert into the limiting groove 14.
[0026] The top of the annular sleeve 10 is provided with multiple positioning grooves 7, and the end of the L-shaped rod 8 matches the positioning grooves 7.
[0027] A retaining ring 4 is connected to the outer side of the annular sleeve 10. The retaining ring 4 is connected to the bottom of the lifting sleeve 3. When the lifting sleeve 3 is connected to the retaining ring 4, it can restrict the lifting sleeve 3 from moving further down. At this time, the positioning block 13 is pressed against the limiting groove 14. At the same time, the end of the locking bolt 6 is aligned with the connecting groove to facilitate the docking of the two.
[0028] The nozzle body 1 is provided with multiple air outlets 2, which are distributed at an angle. There are usually four air outlets 2, with an adjacent angle of 90° and an angle of 45° with the horizontal plane, which can better align with the impurity area 111 and facilitate the blowing operation.
[0029] Working principle: A robotic arm grips the locking component and moves it directly above the nozzle body 1, repeatedly moving it upwards. The air supply unit delivers gas to the air supply pipe 5, which then sprays out from the four air outlets 2 of the nozzle body 1, facilitating the cleaning of impurity areas 111 on the locking component and achieving rapid cleaning. When processing locking components of different sizes, first loosen the locking bolts 6 to release the lifting sleeve 3, then push the lifting sleeve 3 upwards. The lifting sleeve 3 simultaneously applies tension to the three connecting rods 12, causing the connecting rods 12 to pull the positioning block 13 back, separating the positioning block 13 from the limiting groove 14, thus loosening the connection port 9 and facilitating the disassembly of the nozzle body 1. Then, a nozzle body 1 of the corresponding size is installed to meet the cleaning needs of fasteners of different sizes. During installation, the connection port 9 is connected to the air connector 11, and the L-shaped rod 8 is connected to the positioning groove 7, achieving initial positioning of the nozzle body 1. Then drive the lifting sleeve 3 to move down, and the lifting sleeve 3 applies a thrust to the three connecting rods 12 simultaneously. The connecting rods 12 push the positioning block 13 forward, so that the positioning block 13 presses against the limiting groove 14, and applies downward pressure to the connection port 9, thereby improving the stability of the connection between the nozzle body 1 and the air connector 11. Then tighten the locking bolt 6 to fix the lifting sleeve 3, so as to achieve the purpose of quick installation.
