[0026] As a technical optimization of this utility model, a first cylinder 11 is provided on the side of the first guide rail 7 near the first fixed frame 8. The telescopic end of the first cylinder 11 faces upward and is connected to the first guide rail 7. The mounting end of the first cylinder 11 is connected to a second fixed plate 10, and the bottom of the second fixed plate 10 is connected to the top of the frame box 1. The height of the first guide rail 7 can be controlled by the first cylinder 11, allowing the mechanism on the first guide rail 7 to be freely adjusted in height, ensuring the stability of the device's operation.

[0027] As a technical optimization of this utility model, the first feeding mechanism includes a first electric slider 12, a first connecting plate 13 and a second cylinder 14. The first electric slider 12 is slidably installed on the top of the first guide rail 7 near the conveyor belt 2. The first connecting plate 13 is installed on the top of the first electric slider 12. The second cylinder 14 is installed at the bottom of the first connecting plate 13 away from the first guide rail 7. The telescopic end of the second cylinder 14 is close to the conveyor belt 2. The telescopic end of the second cylinder 14 is installed on the third guide rail 20. Two fourth electric sliders 21 are slidably installed inside the third guide rail 20. Clamping blocks are provided on the sides of the two fourth electric sliders 21 that are far apart from each other. The first cylinder 11 drives the first guide rail 7 to extend upward, so that the bottom of the clamping block connected to the second cylinder 14 can move to above the top of the shell workpiece 4. Then, the second cylinder 14 drives the third guide rail 20 to extend, so that the clamping block moves to directly above the shell workpiece 4. Then, the first cylinder 11 drives the first guide rail 7 to move downward, so that the clamping block is inserted into the interior of the shell workpiece 4. Then, the two fourth electric sliders 21 move away from each other, so that the clamping block can complete the clamping work of the shell workpiece 4.

[0028] As a technical optimization of this utility model, the feeding mechanism includes a second electric slider 15, a second connecting plate 16, and a third cylinder 17. The second electric slider 15 is slidably mounted on the top of the first guide rail 7 on the side away from the conveyor belt 2.

Each of the two third electric sliders 19 has a gripper mounted on the side away from the second guide rail 18. The third cylinder 17 drives the second guide rail 18 to move closer to the work station 33. Then, the two third electric sliders 19 move away from each other. As the second guide rail 18 moves closer to the work station 33, the double angle valve moves into the inside of the two grippers. Then, the two grippers move closer to each other to clamp the double angle valve. At this time, the work station 33 is de-energized. Then, with the coordinated movement of the third cylinder 17 and the fourth cylinder 34, the welded double angle valve can be automatically unloaded.

[0029] As a technical optimization of this utility model, the second feeding mechanism includes a fourth guide rail 24, a fifth electric slider 25, a fifth guide rail 26, and a workpiece suction head 29. The fourth guide rail 24 is installed on the side of the first fixed plate 6 near the first fixed frame 8. The fifth electric slider 25 is slidably installed on the side of the fourth guide rail 24 away from the first fixed plate 6. The fifth guide rail 26 is installed on the side of the fifth electric slider 25 away from the fourth guide rail 24. The sixth electric slider 27 is slidably installed on the side of the fifth guide rail 26 away from the fourth guide rail 24. The workpiece suction head 29 is installed on the side of the sixth electric slider 27 away from the fifth guide rail 26, with the end of the workpiece suction head 29 facing downward. The sixth electric slider 27 slides upward in the fifth guide rail 26, causing the bottom of the workpiece suction head 29 to move above the top of the toothed workpiece 23. Then, the fifth electric slider 25 slides in the fourth guide rail 24, causing the workpiece suction head 29 to move closer to the toothed workpiece 23. When the workpiece suction head 29 moves directly above the toothed workpiece 23, the sixth electric slider 27 slides downward, causing the workpiece suction head 29 to move closer to the toothed workpiece 23. When it moves to the preset position, the workpiece suction head 29 picks up the toothed workpiece 23, and through the movement of the fifth electric slider 25 and the sixth electric slider 27, the toothed workpiece 23 moves to the preset position of the fixed housing workpiece 4 on the workstation 33.

[0030] As a technical optimization of this utility model, the workpiece processing mechanism includes a sixth guide rail 31 and a workstation 33. The sixth guide rail 31 is movably mounted on the top of the first fixed frame 8, and a seventh electric slider 32 is slidably mounted on the top of the sixth guide rail 31. The workstation 33 is mounted on the top of the seventh electric slider 32. The workstation 33 places and fixes the housing workpiece 4, facilitating the welding between the housing workpiece 4 and the toothed workpiece 23.

[0031] As a technical optimization of this utility model, a rotary motor 30 is installed at the bottom of the first fixed frame 8. The output end of the rotary motor 30 faces upward and movably passes through the first fixed frame 8. The output end of the rotary motor 30 is connected to the bottom of the sixth guide rail 31. The rotary motor 30 drives the sixth guide rail 31 to rotate 180 degrees. Then, the seventh electric slider 32 slides in the sixth guide rail 31, causing one end of the shell workpiece 4, which has not been welded with the toothed workpiece 23, to move to the welding position of the laser welding head. At this time, the workpiece suction head 29 picks up the toothed workpiece 23 and abuts it at this position. The laser welding head then automatically welds the abutment between the toothed workpiece 23 and the shell workpiece 4, ensuring the smooth operation of the device.

[0032] In use, the top of the conveyor belt 2 can automatically feed the shell workpiece 4, and the vibratory feeder 22 can automatically feed the toothed workpiece 23. The top of the frame box 1 of this device is equipped with a control panel 5, which serves as the carrier of the control system of this device and controls all the automated mechanisms on this device. The linear vibrator 9, vibratory feeder 22 and workpiece suction head 29 used in this device are all existing mature technologies, so they will not be described in detail. The material of the station 33 is an electromagnet, which can fix and release the shell workpiece 4 by turning on and off the power. The clamping block and the gripper are specially made parts that match the shape characteristics of the shell workpiece 4. An automatic laser welding head is preset on the outside of the device to complete the automatic welding of the shell workpiece 4 and the toothed workpiece 23.

[0033] The shell workpiece 4 moves closer to the frame box 1 via the top of the conveyor belt 2. When the shell workpiece 4 moves to the preset position, the reduction motor 3 starts, which slows down the operation of the conveyor belt 2. Then, the first electric slider 12 moves closer to the conveyor belt 2 on the first guide rail 7. At the same time, the first cylinder 11 drives the first guide rail 7 to extend upward, so that the bottom of the clamping block connected to the second cylinder 14 can move to above the top of the shell workpiece 4. Then, the second cylinder 14 drives the third guide rail 20 to extend, so that the clamping block moves to directly above the shell workpiece 4. Then, the first cylinder 11 drives the first guide rail 7 to move downward, so that the clamping block inserts into the interior of the shell workpiece 4. Then, the two fourth electric sliders 21 move away from each other, so that the clamping block can complete the clamping work of the shell workpiece 4.

[0034] After clamping the housing workpiece 4, the first connecting plate 13 moves closer to the first fixing frame 8. When the clamped housing workpiece 4 moves to the preset position above the station 33, the first connecting plate 13 moves downward until the bottom of the housing workpiece 4 abuts the top of the station 33. At this time, the station 33 is energized to complete the fixing of the housing workpiece 4. Then the clamping block releases the housing workpiece 4 and moves closer to the conveyor belt 2 under the drive of the first connecting plate 13 to prepare for clamping the next housing workpiece 4.

[0035] While the shell workpiece 4 is being gripped and fixed, the vibratory feeder 22, driven by the linear vibrator 9, causes the toothed workpiece 23 to move closer to the first fixed frame 8. The sixth electric slider 27 slides upward in the fifth guide rail 26, causing the bottom of the workpiece suction head 29 to move above the top of the toothed workpiece 23. Then, the fifth electric slider 25 slides in the fourth guide rail 24, causing the workpiece suction head 29 to move closer to the toothed workpiece 23. When the workpiece suction head 29 moves directly above the toothed workpiece 23, the sixth electric slider 27 slides downward, causing the workpiece suction head 29 to move closer to the toothed workpiece 23. When it reaches the preset position, the workpiece suction head 29 picks up the toothed workpiece 23, and through the movement of the fifth electric slider 25 and the sixth electric slider 27, the toothed workpiece 23 moves to the preset position of the fixed shell workpiece 4 on the workstation 33, and the toothed workpiece 23 abuts against the shell workpiece 4. Then, the laser welding head automatically welds the abutment of the toothed workpiece 23 and the shell workpiece 4.

[0036] After welding is completed, the workpiece suction head 29 moves back to the vibratory plate 22 to pick up a toothed workpiece 23. At the same time, the rotary motor 30 drives the sixth guide rail 31 to rotate 180 degrees. Then, the seventh electric slider 32 slides in the sixth guide rail 31, so that one end of the shell workpiece 4 that has not been welded with the toothed workpiece 23 moves to the position of the laser welding head. At this time, the workpiece suction head 29 brings the picked-up toothed workpiece 23 to this position, and the laser welding head automatically welds the contact point between the toothed workpiece 23 and the shell workpiece 4.

[0037] After the welding of the toothed part 23 and the housing part 4 is completed, the toothed part 23 and the housing part 4 form a double angle valve. At this time, the third cylinder 17 drives the second guide rail 18 to move closer to the station 33. Then, the two third electric sliders 19 move away from each other. During the movement of the second guide rail 18 towards the station 33, the double angle valve moves into the inside of the two grippers. Then, the two grippers move closer to each other to clamp the double angle valve. At this time, the station 33 is de-energized. Then, under the coordinated movement of the third cylinder 17 and the fourth cylinder 34, the welded double angle valve can be automatically unloaded.

[0038] The device can then repeat the above steps to complete the automatic feeding, welding, and unloading of the double angle valves, eliminating the need for manual operation and greatly enhancing the ease of use of the device.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
