Description

Technical Field

[0001] This invention relates to the field of welding technology, specifically to an automatic welding device. Background Technology

[0002] The production process of the trumpet requires the welding of various components. The tuning ring of the trumpet is one such component that is welded together to connect the parts and allow them to be installed on the trumpet.

[0003] Currently, the existing trumpet tuning ring soldering has the following shortcomings:

[0004] 1. The existing tuning ring position for trumpets is welded manually, which is labor-intensive, fatigue-inducing, and inefficient. It is not conducive to large-scale welding by workers. In addition, the welding head of the welding equipment is at a high temperature when workers are welding the tuning ring, which poses a safety hazard to the operators. If the workers are not attentive during the operation, it can easily cause a safety accident.

[0005] 2. Traditional welding methods involve joining two modules one by one, which cannot be done continuously. This results in slow welding speed and low welding efficiency, which in turn affects the efficiency of product processing. Summary of the Invention

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figure 1-7This invention provides a technical solution: an automatic welding device, including a device body 1. The device body 1 includes a drive motor 3, a first gear 4, a second gear 5, a fixing device 7, a clamp 707, a lifting device 9, a welding mechanism 10, and a connecting pipe 12. The bottom of the device body 1 is welded to the top of a motor base 2. The motor base 2 is fixedly installed to the bottom of the drive motor 3. The first gear 4 is externally mounted on the output end of the drive motor 3. The external teeth of the first gear 4 are distributed in a semi-circular shape. The first gear 4 and the second gear 5 are meshed with each other. The second gear 5 is mounted on the outside of a rotating shaft 501. The rotating shaft 501 is welded to the bottom of a turntable 6. The top of the turntable 6 is provided with a fixing device 7 and a solder bucket 8. The fixing device 7 is distributed in a circular, evenly spaced pattern. On the surface of the turntable 6, the bottom of the lifting device 9 is welded to the top of the device body 1. A welding mechanism 10 is provided on one side of the device body 1. A sensing device 11 is fitted on the outside of the welding mechanism 10. The top of the welding mechanism 10 is connected to a connecting pipe 12. The connecting pipe 12 is annular and its two ends are connected to a welding gun 13. The turntable 6 drives the fixing device 7. When the fixing device 7 rotates to the designated position, the sensing device 11 will drive the lifting device 9. The lifting device 9 will drive the fixing device 7 to move downward, so that the tuning ring can contact the parts inside the module slot 701. Then, the welding mechanism 10 will automatically weld them. Compared with the traditional welding method, this device only needs to fill the gap, which greatly improves the production efficiency and the safety of operation.

[0030] The fixing device 7 is connected to the turntable 6 by bolts. The surface of the fixing device 7 is provided with a module slot 701. The module slot 701 has a rectangular structure. The top of the fixing device 7 is welded to the bottom of the first lifting rod 702. The first lifting rod 702 is a telescopic structure. The first spring 703 is fitted on the outside of the first lifting rod 702, which is conducive to the rotation of the turntable 6 and the rotation of the fixing device 7. By placing the module inside the module slot 701, the tuning ring can contact the module inside the module slot 701 when it moves downward.

[0031] The side of the first lifting rod 702 is connected to one end of the slot 704. The other end of the slot 704 has a groove. The top of the slot 704 is welded to the bottom of the positioning rod 705. There are two positioning rods 705. The two positioning rods 705 are fitted with a second spring 708. The top of the positioning rod 705 is welded to the bottom of the first limiting block 709. The positioning rod 705 is slidably connected to the positioning block 706. The positioning rod 705 can position the movement stroke when the positioning block 706 drives the caliper 707 to move downward, which helps to prevent the caliper 707 from deviating during the downward movement. The second spring 708 can make the positioning block 706 quickly return to its original position downward.

[0032] One end of the positioning block 706 is welded to the caliper 707, the side of the caliper 707 is welded to the side of the lifting block 713, the top of the caliper 707 is welded to the bottom of the first slide rod 710, a third spring 712 is fitted on the outside of the first slide rod 710, the top of the first slide rod 710 is welded to the bottom of the pull rod 711, the first slide rod 710 is slidably connected to the fixed arm 714, and one end of the fixed arm 714 is welded to the top of the first lifting rod 702. Thus, by pulling the pull rod 711 upward, the pull rod 711 can drive the caliper 707 to move upward through the first slide rod 710, and the third spring 712 can drive the caliper 707 to reset downward to clamp the tuning ring.

[0033] The bottom of the lifting device 9 is fitted with a fixed base 901, which is connected to the main body 1 of the device by bolts. One side of the fixed base 901 is connected to the bottom of the hydraulic rod 902 via a shaft. The top of the hydraulic rod 902 is shaft-connected to one end of the connecting rod 903. The other end of the connecting rod 903 is welded to one end of the second lifting rod 904. The middle part of the connecting rod 903 is shaft-connected to the top of the lifting device 9. Thus, the hydraulic rod 902 drives one end of the connecting rod 903 to move up and down, which in turn drives the second lifting rod 904 to move up and down. This allows the second lifting rod 904 to drive the lifting block 713 to move up and down, so that the slot 704 can move up and down and contact the module inside the module slot 701.

[0034] The bottom of the groove at one end of the card slot 704 has an arc-shaped structure, and the top of the caliper 707 has an arc-shaped structure. The side of the caliper 707 is welded to the clamping block 715. There are two clamping blocks 715, which are distributed on both sides of the caliper 707, so that the tuning ring can be fixed inside the groove at one end of the card slot 704, and the bottom of the tuning ring should not shake, causing the welding to deviate.

[0035] The stroke of the first gear 4 intermittently driving the second gear 5 to rotate is the same as the stroke of the turntable 6 driving the fixing device 7 to rotate, so that the turntable 6 can rotate the fixing device 7 to the designated welding position each time it rotates. This helps the turntable 6 to orderly transport the fixing device 7 to the designated position, thereby achieving the effect of automatic welding and improving welding efficiency.

[0036] In use, by pulling up the lever 711, the first slide rod 710 moves the caliper 707 upward, thereby hooking the tuning ring into the groove at one end of the slot 704. The downward push of the third spring 712 causes the caliper 707 to return to its original position and clamp the tuning ring. The drive motor 3 drives the first gear 4 to rotate, which in turn drives the second gear 5 to rotate, causing the turntable 6 to rotate intermittently. This allows the fixing device 7 to automatically rotate intermittently to the designated welding position. When the fixing device 7 reaches the designated position, the sensor... The device 11 drives the lifting device 9, which in turn drives one end of the connecting rod 903 to move up and down via the hydraulic rod 902. This, in turn, drives the second lifting rod 904 to move up and down, which in turn drives the lifting block 713 to move up and down. This allows the slot 704 to move up and down and contact the module inside the module slot 701. Then, the welding gun 13 at the bottom of the welding mechanism 10 performs automatic welding. Compared with the traditional welding method, this device only requires filling, which greatly improves production efficiency and operational safety.
