Background Art

Gears, as the transmission structure of mechanical parts, have been used in many mechanical devices. Gears refer to mechanical components with teeth on the wheel rim that can continuously mesh to transmit motion and power. Gear transmission applications have appeared very early. At the end of the 19th century, special machine tools and tools for gear cutting based on the principle of gear cutting also appeared one after another. With the development of production, the stability of gear operation has been paid attention to.

Gears may have broken teeth and other wear during use. At this time, welding equipment is needed to weld at the missing teeth. The existing welding equipment needs to manually position the welding gears one by one, and cannot fix multiple groups.

With the connection and reinforcement of the two support rods 10, the welding table 8 can be set up under the welding hand 3 to match the workpiece placement;

A push rod 14 extends from the edge of one end of the welding table 8, and fixed tables 9 are fixedly installed on the upper surfaces of both sides of the welding table 8.

A clamping seat 35 is fixedly installed on the outer side of one end of the carrying box 42 and corresponds to the position of the clamping shaft 33. The lever 34 is movably mounted on the inner side of the clamping seat 35, and one end of the push rod 14 contacts with the surface of one end of the carrying box 42. After welding is completed, waste chips will fall into the lower inner side of the corresponding carrying box 42, and then the lever 34 falling on the inner side of the clamping seat 35 will be rotated in the opposite direction at a later stage, and the carrying box 42 can be pulled out from one end of the welding table 8, and then the waste chips can be poured out.

A U-shaped frame 12 is fixedly installed on the inner side of the two sets of fixed platforms 9, and the inner sides of the two U-shaped frames 12 are connected to a slide 29 through a set driving mechanism. A latching mechanism is set on one side of the two sets of slides 29, and multiple sets of supporting legs 2 are fixedly set at the bottom end of the welding frame 1.

The driving mechanism includes a screw 15 rotatably mounted on the inner side of the U-shaped frame 12, a motor 11 is fixedly mounted on one end of the screw 15, the motor 11 is fixedly connected to the U-shaped frame 12, the screw 15 is threadedly engaged with a slide 29, and the slide 29 is slidably mounted on the inner side of the U-shaped frame 12. After the motor 11 is connected to a power source, the output end can drive the screw 15 to rotate, thereby allowing the threaded slide 29 to move horizontally on the inner side of the U-shaped frame 12.

The latching mechanism includes a base 28 that is fixedly mounted on the outer wall of one side of the slide 29, a first cylinder 19 is fixedly mounted on the inner side of the base 28, an L-shaped rod 23 is fixedly mounted on the telescopic end of the first cylinder 19, an insertion rod 25 is inserted on the inner side of the L-shaped rod 23, two groups of connecting blocks 27 are fixedly mounted on the outer sides of both ends of the insertion rod 25, a mounting rod 24 is fixedly mounted on one side of the four groups of connecting blocks 27, a circular frame 26 is fixedly mounted on the upper outer sides of the four mounting rods 24, the connection between the connecting block 27 and the insertion rod 25 can facilitate the first cylinder 19 to drive multiple mounting rods 24 to move synchronously, so that the pushing components can be close to each other and pressed against the outer side of the toothless gear, pushing components are arranged on the inner sides of the four groups of circular frames 26, and fixing parts are fixedly arranged on the upper surface of one side of the four groups of circular frames 26.

The pushing assembly includes a card plate 31 fixedly mounted on the inner side of the circular frame 26, and a second cylinder 41 is fixedly mounted on the inner side of the card plate 31. Under the connection between the card plate 31 and the circular frame 26, a connecting plate 21 is fixedly mounted on the telescopic end of the second cylinder 41, and a sliding rod 40 is installed on the outer wall of one side of the connecting plate 21 at equal distances along the circumferential direction. A card shell 37 is fixedly mounted on the outer side of one end of the sliding rod 40, and a ball 39 is rotatably mounted on the inner side of the card shell 37.

The second cylinder 41 can be flexibly extended and retracted at the front end of the first cylinder 19, and can drive the connecting plate 21, the slide rod 40 and the card shell 37 of the corresponding retractable end to move, thereby prompting the card shell 37 and the ball 39 on the outside of one end of the slide rod 40 to approach the outside of the toothless gear. The ball 39 can cooperate with the toothless gear to rotate in the current position, so that different positions on the outside of the same gear can be welded.

The fixing parts include connecting rods 22 fixedly mounted on the upper surface of one side of the circular frame 26, and an annular shell 30 is fixedly mounted on one end of the connecting rod 22 away from the circular frame 26. The annular shell 30 can be pressed against the outer side of the toothless gear in an annular shape, thereby improving the stability effect during fixation. A contact component is provided on the outer wall of one side of the annular shell 30, and one end of the sliding rod 40 is slidably inserted into the inner side of the annular shell 30.

The contact assembly includes a ring 32 fixedly mounted on the outer wall of one side of the ring shell 30, and a plurality of groups of abutment blocks 38 extend from the outer side of the ring 32. The abutment blocks 38 can be conveniently abutted against the outer side of the toothless gear.

A connecting pipe 20 is fixedly inserted into the inner side of the connecting rod 22, and an air outlet bin 36 is fixedly installed at one end of the connecting pipe 20. A transverse pipe 18 is installed on the outer side of one end of the connecting pipe 20 away from the air outlet bin 36. The inner sides of both ends of the transverse pipe 18 are connected to a cooling fan 16 through a conveying pipe 17 installed in communication. The cooling fan 16 is fixedly installed on the upper surface of the base 28.

The cooling fan 16 can deliver the airflow to the cross pipe 18 through the delivery pipe 17 connected at both ends, and then deliver it to the inner side of the connecting pipe 20 at various positions through the cross pipe 18, and finally blow it to the surface of the toothless gear through the air outlet bin 36 to cool the welding point and make it form faster.

Working principle: When in use, the worker places the tooth angle of the missing tooth gear vertically on the upper surface of the carrying box 42, and then the first cylinders 19 on the corresponding two sides will drive the L-shaped rod 23 to move toward the two sides of the missing tooth gear, causing the multiple groups of abutment blocks 38 on the outside of the ring 32 to abut against the outside of the missing tooth gear, and move horizontally to the bottom of the welding hand 3 under the drive mechanism. The second cylinder 41 can push out the sliding rod 40 and the ball 39 on the inside of the card shell 37 inside the circular frame 26, so that the multiple groups of ball 39 abut against the outside of the missing tooth gear. At this time, the first cylinder 19 can drive the ring 32 away from the missing tooth gear, and the worker can then move it to the original position according to the position of the missing tooth. The toothless gear is rotated so that the missing position of the toothless gear corresponds to the position of the welding hand 3, and then the second cylinder 41 drives the ball 39 to return to the inside of the ring shell 30, and the first cylinder 19 again prompts the abutment block 38 on the outside of the ring ring 32 to abut and fix it. As a result, the missing positions of the toothless gear at different positions can be quickly adjusted to cooperate with the welding operation. In this way, the missing positions at different positions on the outside of the same toothless gear can be quickly welded, thereby improving the welding efficiency of the toothless gear, and after welding, the cooling fan 16 and the air outlet bin 36 can be used to quickly cool the welding position, which can reduce the workers' frequent fixing of the gear position, saving time and effort.
