Description

Technical Field

[0001] The invention belongs to the technical field of metal parts processing equipment, and in particular relates to a safety belt gear welding, pressing and rotating mechanism. Background Art

[0002] The rapid popularization of automobiles has forced people to pay attention to a series of issues such as automobile safety, energy conservation, and environmental protection, and automobile safety issues are the first to bear the brunt. Automobile seat belts are traditional passive safety configurations to ensure safe driving. When a violent collision occurs during driving, the pretensioner can tighten the seat belt to limit the position of the driver or passengers and avoid collisions between people and objects such as the steering wheel, windshield, seat backs, and doors in the car. The seat belt gear is one of the most critical parts used in automobile seat belts and their systems. When the automobile seat belt is buffered, the gear needs to rotate to provide buffering force and finally pull the seat belt, so its importance can be seen.

[0003] The current production process of seat belt gears is to first punch and cut the plate on a vertical punch press, then saponify it, and then process it on a vertical three-station cold forging press. The forged parts are then vibrated and cleaned, and finally two small gears with the same processing are welded and formed before being electroplated.

[0004] In the subsequent welding process, workers place the two small gears on special welding equipment for welding. Each welding requires manual selection of small gears, and placing the two small gears in the correct position, one positive and one negative. Then, the welding equipment is held manually to weld one circle of the gear, or the welding equipment is driven by a robotic arm to weld around the gear. After welding, the parts are taken out manually and the next set of parts are installed. This reciprocating cycle is repeated. This method requires manual loading and unloading of materials, which is inefficient, has high requirements on the movement accuracy of the robotic arm, and requires a large working space. In addition, metal debris and smoke will be generated during the welding process, affecting the safety of the operator. Summary of the invention

[0005] In order to solve the above technical problems, the purpose of the present invention is to provide a safety belt gear welding clamping and rotating mechanism, which occupies a small space and can automatically and continuously complete welding, thereby improving production efficiency.

During welding, the rotary clamping head is driven by the downward pressure cylinder to press the semi-gear disk, and the smoke extraction and dust removal hood covers it to reduce the splashing of debris and smoke. At the same time, the forward and backward moving servo mechanism drives the closed rotating gear to engage with the rotating gear on the tool positioning mechanism, and is driven to rotate by the speed rotating motor.

The cam divider 7 drives the outer turntable 2 to rotate intermittently. A plurality of tooling positioning mechanisms 3 are arranged at intervals along the outer edge of the outer turntable 2. The tooling positioning mechanism includes a positioning column 33, which is inserted on the outer turntable 2 through a turntable fixing seat 31. A rotating fixing seat 32 is also provided between the positioning column 33 and the turntable fixing seat 31, so that the positioning column 33 is rotatably connected with the turntable fixing seat 31. A rotating gear 34 is also fixed to the lower part of the positioning column 33.

[0042] The clamping and rotating mechanism includes a supporting frame, a pressing cylinder 103, a smoke extraction and dust removal hood 104, a rotating clamping head 1041, a forward and backward moving servo mechanism 106, a speed rotating motor 1051 and a closed rotating gear 1052. The pressing cylinder 103 is fixed on the top of the supporting frame, and the piston rod of the pressing cylinder 103 penetrates through the supporting frame and is connected to the smoke extraction and dust removal hood 104. The rotating clamping head 1041 is fixed in the middle of the smoke extraction and dust removal hood 104. The forward and backward moving servo mechanism 106 is fixed at the bottom of the supporting frame. The speed rotating motor 1051 and the closed rotating gear 1052 are arranged on the forward and backward moving servo mechanism 106 through a fixing seat 105, and the speed rotating motor 1051 drives the closed rotating gear 1052 to rotate. A speed detection encoder for real-time checking of the welding speed is also provided on the fixing seat. The forward and backward moving servo mechanism 106 drives the closed rotating gear 1052 to engage or disengage with the rotating gear 34, thereby driving the positioning column 33 to rotate or stop.

[0043] The welding gun movement mechanism includes a support seat 107 and a laser welding gun body 1010 . The laser welding gun body 1010 is arranged on the support seat 107 through a welding gun forward and backward movement servo mechanism 108 and a welding gun up and down movement servo mechanism 109 , and the laser welding gun body 1010 is aligned with the half gear plate 100 on the positioning column 33 .

[0044] The tooling positioning mechanism also includes a support claw 38, a tensioning head 37 and a tensioning cylinder 36. A through hole is provided in the middle of the positioning column 33, and the lower parts of multiple support claws 38 are inserted in the through hole. The tensioning head 37 is located in the center of the multiple support claws 38. The tensioning cylinder 36 is fixed to the bottom of the outer turntable 2 through the cylinder fixing block 20, and is connected to the tensioning head 37 through the cylinder connecting block 35, driving the tensioning head to move, so that the support claws open or contract, thereby causing the half gear disk 100 to be stuck or loosened.

[0045] A stop block 39 is also provided on one side of the rotating column 33. A locking mechanism 4 is provided on the rotating disk assembly. The locking mechanism 4 cooperates with the stop block 39 to make the rotating column 33 rotate or remain stationary. The locking mechanism includes a locking base 41, a connecting hook 43, a rotating locking block 44, and a rotating positioning cylinder 5 fixed on the inner fixed disk. The locking base 41 is fixed on the outer rotating disk 2. The rotating locking block 44 is slidably arranged on the upper part of the locking base 41. The locking base 41 and the rotating locking block 44 are provided with springs so that the rotating locking block 44 is close to the positioning column 33. A connecting hook 43 is also provided at one end of the rotating locking block 44. The rotating positioning cylinder 5 drives the connecting hook 43 away from the positioning column.

[0046] A rotating locking block 44 is arranged on the inner side of each positioning column 33, and there is one rotating positioning cylinder 5; in other embodiments, there may be multiple rotating positioning cylinders 5, and the rotating positioning cylinders 5 do not rotate with the outer turntable 2. The number of rotating positioning cylinders matches the number of processes that require the positioning column to rotate freely. Rotating positioning cylinders are only required to be arranged in the processes where the positioning column needs to rotate freely. This can both meet the processing requirements and save costs.

[0047] A block is fixed to the movable end of the rotary positioning cylinder 5, the upper end surface of the block is higher inside and lower outside, the connecting claw 43 is connected to the end of the rotary locking block 44, and can move up and down, and the top of the block is higher than the lower end of the connecting claw 43. Such a structure enables the rotary positioning cylinder 5 to push the block, the connecting claw 43 slightly tilts upward, and the block can be inserted under the connecting claw 43, and the connecting claw 43 falls under the action of gravity. When the rotary positioning cylinder retreats, the block can drive the connecting claw 43 to retreat, so that the rotary locking block 44 is separated from the limit block 39, and the positioning column can rotate freely.

[0048] A support stand 62 is also fixed on the work surface 1 around the outer turntable 2, and a support roller 62 is rotatably arranged on the top of the support stand 62, and the support roller 62 abuts against the bottom of the outer turntable 2. The arrangement of the support stand 62 and the support wheel can play a certain supporting role on the turntable assembly, which is conducive to smoother rotation of the turntable.

[0049] The support frame includes two support columns 102, and a top plate 1020 and a bottom plate 1024 fixed to the support columns 102. A downward pressing guide sleeve 1023 is fixed to the top plate 1020. A guide rod 1022 is slidably arranged in the downward pressing guide sleeve 1023. A fixing plate 1021 is fixed to the lower end of the guide rod 1022. The piston rod of the downward pressing cylinder 103 is connected to the upper end of the fixing plate 1021. The rotary pressing head 1041 and the smoke and dust removal hood 104 are fixed to the lower end of the fixing plate 1021. The forward and backward moving servo mechanism 106 is fixed to the bottom plate 1024 through the support plate 1060, and the fixing seat 105 is connected to the slider 1061 on the forward and backward moving servo mechanism 106.

[0050] The laser welding gun body 1010 is also provided with a gas flow meter 1011, and welding protection gas pipes 1012 are also provided on both sides of the laser welding gun body 1010. The gas flow meter is used to switch gas protection and monitor the gas flow; the welding protection gas pipe ensures gas protection during welding at the welding position; the forward and backward moving servo mechanism, the welding gun forward and backward moving servo mechanism 108, and the welding gun up and down moving servo mechanism 109 in the present invention can all adopt structures such as linear motors.

[0051] The working process of the present invention is as follows: the half gear disk is placed on the positioning column manually or by other equipment, the tensioning cylinder drives the tensioning head to open the claws to position the half gear disk, the motor drives the cam divider to rotate through the belt, and then the outer turntable rotates intermittently to each process. When the turntable assembly arrives at the clamping and rotating mechanism with the tooling positioning mechanism, the downward pressure cylinder drives the guide rod, the smoke and dust removal hood, and the rotating clamping head to press the parts, and then the rotating positioning cylinder drives the rotating locking block to retreat, and the forward and backward moving servo mechanism drives the fixed seat, the speed rotating motor, and the speed detection encoder to push in to make the closed rotating gear engage with the fixture rotating gear. At the same time, the welding gun moves up and down servo mechanism and the welding gun moves forward and backward servo mechanism automatically adjusts the servo position (a component detection mechanism can be set on the rotation path of the turntable assembly, and the position adjustment of the laser welding gun body is adjusted according to the detection parameters of the component detection mechanism). After the laser welding gun body 1010 reaches the position, the gas flow meter is turned on, and the laser welding equipment emits light after the welding protection air pipe exhausts gas, and the speed rotating motor rotates and drives the speed detection encoder to start welding.

[0052] When the rotation is finished, the speed rotating motor returns to zero position (reverse), the rotating positioning cylinder drives the rotating locking block to be pushed out, the pressing cylinder drives the guide rod, smoke extraction and dust removal hood, and rotating pressing head to rise, the forward and backward moving servo mechanism drives the fixed seat, speed rotating motor, and speed detection encoder to retreat, and the turntable assembly rotates to enter the next station.
