A rotating component 7 for welding automotive accessories is provided at the center of the welding table 2, and the orientation of the welding head 77 is flexibly switched to meet the continuous welding requirements of the four groups of automotive accessories in the positioning state, thereby further improving the welding efficiency of automotive accessories.

[0046] like Figure 5-Figure 11As shown, a driving bevel gear 52 is fixedly connected to an output shaft of the double-headed motor 51, and driven bevel gears 53 are arranged around the driving bevel gear 52. A first electric push rod 54 is fixedly connected to the side of the driven bevel gear 53 away from the driving bevel gear 52. The double-headed motor 51 first provides a unified driving source to save power costs. Then, four groups of first electric push rods 54 are used to adjust the meshing stroke between the driven bevel gear 53 and the driving bevel gear 52. The outer side of the first electric push rod 54 is provided with a threaded rod 55 that rotates with the fixed cover 4. A threaded sleeve 56 is threadedly connected to the threaded rod 55. Then, the threaded sleeve 56 is driven by the four groups of threaded rods 55 to move synchronously outward or inward, providing four-way positioning drive compensation for the four groups of automotive accessories and facilitating their positioning.

[0047] The positioning assembly 6 includes a slide rail groove 61 opened on the side facing the welding table 2 and the fixed cover 4, and the inner cavity of the slide rail groove 61 is slidably connected to a sliding member 62 fixedly matched with the threaded sleeve 56, the top of the sliding member 62 is fixedly connected to a stop seat 63, and the outer side of the stop seat 63 is fixedly connected to a positioning suction cup 64, and the four groups of threaded sleeves 56 achieve the effect of synchronously moving outward or inward on the four groups of stop seats 63 and the positioning suction cup 64, and the inner cavity of the fixed cylinder 3 is fixedly connected to a limit spring 65, and the inner side of the limit spring 65 is fixedly connected to the inner side of the limit spring 65. A T-shaped rod 66 is fixedly connected to the fixed cylinder 3 for sliding cooperation, and a material discharge seat 67 used in cooperation with the positioning suction cup 64 is fixedly connected to the inner side of the T-shaped rod 66, and the four groups of limit springs 65, the T-shaped rod 66 and the material discharge seat 67 play the role of pre-discharging and elastic buffering for the automobile parts to be welded, and then the four groups of stop seats 63 and the positioning suction cup 64 adsorb and press the automobile parts to be welded on the four groups of material discharge seats 67, so as to achieve the four-way synchronous positioning effect of the four groups of automobile parts, and also improve the welding efficiency of automobile parts;

[0048] The positioning suction cup 64 and the discharge seat 67 are distributed in an axially symmetrical state along the central axis of the welding table 2, which is convenient for synchronous positioning of four groups of automotive parts to be welded, and the bottom of the discharge seat 67 is slidably connected to the welding table 2, which plays a role of sliding limit for the discharge seat 67 and improves the stability of the discharge seat 67 during movement.

[0049] The rotating assembly 7 includes a second electric push rod 71 embedded in the output shaft of the double-headed motor 51 close to the driving bevel gear 52, and the piston rod of the second electric push rod 71 is fixedly connected to the limiting head 72, a rotating sleeve 73 is embedded in the center of the welding table 2, and the inner cavity of the rotating sleeve 73 is rotatably connected to a turntable 74, and a limiting groove 75 is provided at the bottom of the turntable 74 to engage with the limiting head 72, and the engaging stroke between the limiting head 72 and the limiting groove 75 is adjusted by the second electric push rod 71, and a support arm 76 is fixedly connected to the top of the turntable 74, and the other end of the support arm 76 is fixedly connected to a welding head 77 used in conjunction with the positioning suction cup 64 and the discharge seat 67, and the rotating sleeve 73 and the turntable 74 play a role of rotational support for the welding head 77 on the support arm 76. Under the drive of the double-headed motor 51 as a unified driving source, the orientation of the welding head 77 is flexibly switched to meet the continuous welding requirements of four groups of automobile parts in the positioning state, and further improve the welding efficiency of automobile parts;

[0050] An industrial camera 9 is fixedly connected to one side of the welding head 77 through a support, and the industrial camera 9 is distributed in an inclined state toward the welding position of the welding head 77, so as to shoot, locate and detect the image between the welding head 77 and the automotive parts. A protective cover 10 that is staggered with the stop seat 63 is fixedly connected to the outer side of the welding table 2 near the rotating sleeve 73, and a ratchet 11 is fixedly connected to one side of the turntable 74 near the support arm 76. Both sides of the ratchet 11 are clamped with pawls 12 that are rotatably matched with the protective cover 10, and the outer side of the pawl 12 is fixedly connected with a support spring 13 that is fixedly matched with the protective cover 10, which plays a reverse limiting role on the ratchet 11 that rotates synchronously with the turntable 74 to prevent the welding head 77 from being misaligned when welding automotive parts.

[0051] like Figure 12-13 As shown, during the welding process of automobile parts, debris and smoke will be generated. Most of the time, only the smoke can be processed, and the debris and smoke cannot be cleaned by negative pressure suction and filtering cleaning, resulting in debris and smoke being left at the processing site, affecting the welding quality of automobile parts, and also reducing the cleanliness of the welding site. Cleaning components 8 are arranged around the top of the welding table 2, and the cleaning components 8 include a driving circular gear 81 fixed on another output shaft of the double-headed motor 51, and the driving circular gear 81 is meshed with driven circular gears 82 around it. The double-headed motor 51 drives four groups of driven circular gears 82 to rotate synchronously through the driving circular gear 81;

[0052] The inner cavity of the driven circular gear 82 is fixedly connected with a rotating rod 83 that rotates with the fixing frame 1 and the welding table 2. The top of the rotating rod 83 is fixedly connected with flexible brush strips 84 that are used in conjunction with the filter plate 14. The four sets of driven circular gears 82 drive the four sets of flexible brush strips 84 through the four sets of rotating rods 83 to clean and filter the debris particles splashed on the filter plate 14 to prevent the debris particles from clogging the mesh of the filter plate 14. The rotating rod 83 is fixedly connected with a dust collecting fan 85 near the top of the flexible brush strip 84. The dust collecting fan 85 is designed with streamlined lightweight materials.

[0053] A dust hood 86 that is snap-fitted with the protective cover 10 is provided on all sides of the top of the welding table 2. A dust fan 85 that rotates synchronously with the flexible brush strip 84 generates negative pressure suction into the dust hood 86, so that the debris and smoke generated during welding are negatively absorbed into the dust hood 86, and then filtered and separated by the filter plate 14. In addition, the welding table 2 is fixedly connected with a holder 87 that is snap-fitted with the dust hood 86 near the fixed cylinder 3, which is convenient for disassembly and assembly of the dust hood 86, and also convenient for unified cleaning of large particles of debris accumulated on the filter plate 14.

[0054] The inner cavity of the welding table 2 is fixedly connected with filter plates 14 that are staggered with the fixed cover 4 on all sides to filter the smoke generated during the welding of automobile parts, and the inner side of the top of the filter plate 14 is fixedly connected with a small vibration motor 15 to vibrate the debris adsorbed and dropped on the filter plate 14, so that small particles of debris can pass through the filter plate 14 and fall, and large particles of debris can be vibrated out of the mesh area of ​​the filter plate 14 to prevent blockage. The bottom of the welding table 2 is fixedly connected with a fixed dust box 16 that is staggered with the fixed cover 4 on all sides, and a pull-out dust box 17 is clamped on the outer side of the fixed dust box 16, so that small particles of debris can be stored and collected, and the pull-out dust box 17 can also be pulled out, so that the small particles of debris falling into the fixed dust box 16 and the pull-out dust box 17 can be uniformly processed.

[0055] The working principle of a welding auxiliary device for automobile parts production and processing is as follows: first, four groups of automobile parts to be welded are placed on four groups of material discharging seats 67 respectively, and then the four groups of first electric push rods 54 are controlled to start synchronously and drive the four groups of driven bevel gears 53 to reach the meshing part of the driving bevel gear 52, and then the double-headed motor 51 is controlled to start and drive the four groups of driven bevel gears 53 to rotate synchronously through the meshing driving bevel gear 52, and the four groups of driven bevel gears 53 drive the four groups of threaded rods 55 to rotate synchronously, and the four groups of threaded rods 55 drive the four groups of threaded sleeves 56 to move outward synchronously;

[0056] With the cooperation of the four groups of slide rail grooves 61 for the four groups of sliding members 62 to limit the sliding position, the four groups of threaded sleeves 56 drive the stop seats 63 on the four groups of sliding members 62 to move outward synchronously, and the four groups of stop seats 63 drive the four groups of positioning suction cups 64 to adsorb and press the automobile parts to be welded placed on the four groups of discharge seats 67 to the outside. At the same time, the positioning suction cups 64 on the four groups of stop seats 63 also force the four groups of discharge seats 67 to drive the four groups of T-shaped rods 66 to slide in the four groups of fixed cylinders 3, and compress the four groups of limit springs 65, and the industrial camera 9 positions and shoots the pictures thereof until the positioning suction cups 64 on the four groups of stop seats 63 adsorb and press the automobile parts to be welded on the four groups of discharge seats 67 to the bottom of the welding head 77, thereby completing the synchronous positioning of the four groups of automobile parts to be welded.

[0057] According to the size of the auto parts, one or more of the first electric push rods 54 can be controlled to open, and one or more of the threaded rods 55 can be controlled to drive the threaded sleeves 56 to move outwards. The specific situation depends on the auto parts. After the four sets of auto parts to be welded complete the synchronous positioning work, the double-headed motor 51 is controlled to pause first, and then the four sets of first electric push rods 54 are controlled to close and drive the four sets of driven bevel gears 53 to disengage from the meshing part of the driving bevel gear 52 to the initial position.

[0058] Next, the second electric push rod 71 is controlled to start and drive the limit head 72 to move up and clamp into the limit slot 75 at the bottom of the turntable 74, then the double-headed motor 51 is controlled to start and drive the turntable 74 to rotate in the rotating sleeve 73 through the limit head 72 that is clamped in place. At this time, the driving bevel gear 52 on the double-headed motor 51 is in an idling state, and the driving circular gear 81 on the other output shaft is in a rotating state. The turntable 74 drives the welding head 77 to rotate and adjust accordingly through the support arm 76, and the industrial camera 9 is used to locate and shoot the welding picture between the automobile parts and the welding head 77, and then the welding head 77 that has switched to the right position performs welding operations on four groups of automobile parts in different positions;

[0059] When the turntable 74 rotates, the turntable 74 also drives the ratchet 11 to rotate synchronously in the protective cover 10, and the ratchet 11 drives the four groups of pawls 12 to produce a tooth-jumping action on its surface, and the four groups of supporting springs 13 provide elastic support and cooperation for the four groups of pawls 12, so as to realize reverse restriction of the ratchet 11 and the turntable 74. After the welding operation of the four groups of automobile parts is completed, the double-headed motor 51 is first controlled to pause, and then the second electric push rod 71 is controlled to close and drive the limit head 72 to move down and leave the limit groove 75 at the bottom of the turntable 74 to the initial position, and conversely, the positioning suction cups 64 on the four groups of stop seats 63 are controlled to loosen the automobile parts placed on the four groups of material discharge seats 67 to complete welding, and then the four groups of automobile parts that have completed welding are removed from the four groups of material discharge seats 67, and then the next batch of automobile parts to be welded are placed;

[0060] During the welding of the automobile parts by the welding head 77, while debris and smoke are generated, the other output shaft of the double-headed motor 51 drives the driving circular gear 81 to rotate, and the driving circular gear 81 drives the rotating rods 83 on the four sets of driven circular gears 82 to rotate synchronously, and the four sets of rotating rods 83 drive the four sets of flexible brush strips 84 and the dust suction fans 85 to rotate synchronously in the four sets of dust suction hoods 86. The four sets of dust suction fans 85 in the rotating state generate negative pressure suction in the four sets of dust suction hoods 86, and negatively absorb the debris and smoke generated by the automobile parts in the welding state on the four sets of discharge seats 67 into the four sets of dust suction hoods 86. The smoke is filtered by the four sets of filter plates 14 and then enters the fixed dust box 16 and the pull-out dust box 17, and is discharged from the exhaust groove reserved therein;

[0061] While debris accumulates on the four groups of filter plates 14, the four groups of flexible brush strips 84 clean the debris accumulated on the four groups of filter plates 14, and at the same time, the four groups of small vibration motors 15 assist in vibrating the debris on the four groups of filter plates 14 to prevent the debris from clogging the four groups of filter plates 14 and affecting the filtering and discharge of smoke. Small-volume debris passes through the four groups of filter plates 14 and falls into the four groups of fixed dust boxes 16 and the pull-out dust boxes 17. After all the automobile parts are welded, the four groups of pull-out dust boxes 17 are pulled out from the four groups of fixed dust boxes 16, and the small-volume debris that falls into the four groups of fixed dust boxes 16 and the pull-out dust boxes 17 are cleaned up uniformly. At the same time, the four groups of dust hoods 86 are pulled out from the four groups of card seats 87, and the large-particle debris left on the four groups of filter plates 14 are cleaned up uniformly.

[0062] It should be noted that the specific models and specifications of the double-headed motor 51, the first electric push rod 54, the second electric push rod 71, the welding head 77, the industrial camera 9 and the small vibration motor 15 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be repeated in detail.

[0063] The power supply circuits of the double-headed motor 51, the first electric push rod 54, the second electric push rod 71, the welding head 77, the industrial camera 9 and the small vibration motor 15 are clear to those skilled in the art and will not be described in detail here.
