[0031] As a technical optimization solution of the present invention, the fixing mechanism includes a limit block 9 installed on the top of the base plate 1, and a limit groove 14 for limiting the bicycle front fork 12 is opened on the top of the limit block 9.

[0032] As a technical optimization solution of the present invention, a loading box 10 is installed on the side of the limit block 9 close to the fixed plate 8, a unloading box 11 is installed on the top of the bottom plate 1, the fixed plate 8 is located between the loading box 10 and the unloading box 11, and the loading box 10 and the unloading box 11 are located between the two first guide rails 2.

[0033] When the present invention is in use, when it is necessary to weld the bicycle front fork 12 and the bicycle beam 13, first, the bottom end of the bicycle front fork 12 to be welded is inserted into the limiting groove 14 at the top of the limiting block 9, and the bicycle beam 13 to be welded is transferred to the loading box 10.

[0034] The first electric slider 3 is started, and the first electric slider 3 moves horizontally on the first guide rail 2, so that the first electric slider 3 drives the fixed plate 8 to move closer to the lower material box 11, so that the two mounting blocks 29 are located obliquely above the loading box 10 and then stop. At this time, the first electric telescopic rod 7 is started, and the piston rod of the first electric telescopic rod 7 retracts to make the fixed plate 8 move downward, so that the mounting block 29 located below moves down to the side of the bicycle beam 13, and the other mounting block 29 moves down to the top of the bicycle beam 13. At this time, the first electric slider 3 is started again, so that the fixed plate 8 moves closer to the bicycle beam 13, thereby making One of the mounting blocks 29 is inserted into the inner circle of the bicycle frame 13, and the other mounting block 29 moves to the top of the bicycle frame 13. At this time, the two third electric sliders 22 are started at the same time. The two third electric sliders 22 move close to each other on the third guide rail 21, so that the two mounting blocks 29 move close to each other. At this time, one of the two mounting blocks 29 is located inside the bicycle frame 13, and the other mounting block 29 is located outside the bicycle frame 13. The two mounting blocks 29 move close to each other, which can make the two arc blocks 36 move close to each other, and the two second electric telescopic rods 35 are started at the same time, so that the two arc blocks 36 move close to each other. The spacing between the blocks 36 is smaller than the spacing between the two welding gun heads 31. The bicycle beam 13 can be clamped and fixed by moving the two arc blocks 36 closer to each other. The bicycle beam 13 can be clamped and fixed by the two arc blocks 36, and the two third electric sliders 22 can be moved up and down on the third guide rail 21 to make the two arc blocks 36 move up and down, so that the inner circle of the bicycle beam 13 clamped and fixed by the two arc blocks 36 is concentric with the annular second guide rail 18. At this time, the first electric telescopic rod 7 is started, and the piston rod of the first electric telescopic rod 7 pushes the fixing plate 8 to move upward, thereby making the two arc blocks The block 36 clamps the fixed bicycle beam 13 and moves it upward until the bicycle beam 13 moves to the welding position with the bicycle front fork 12 and stops. At this time, the first electric slider 3 is started again to make the fixing plate 8 move closer to the bicycle front fork 12, and then the two arc-shaped blocks 36 clamp the fixed bicycle beam 13 and move closer to the bicycle front fork 12 until the welding position of the bicycle beam 13 contacts the welding position of the bicycle front fork 12 and then stops. It can automatically complete the loading process of the bicycle beam 13, and there is no need for manual loading of the bicycle beam 13, thereby improving the degree of automation of the device when in use.

[0035] When the welding part of the bicycle beam 13 contacts the welding part of the bicycle front fork 12, the fourth electric telescopic rod 39 is started, and the piston rod of the fourth electric telescopic rod 39 pushes the roller 40 to move closer to the bicycle beam 13 until the roller 40 contacts the end of the bicycle beam 13, and the bicycle beam 13 is clamped and fixed by the roller 40 and the limited bicycle front fork 12. The bicycle beam 13 can be clamped and fixed between the bicycle front fork 12 and the roller 40, and the bicycle beam 13 can be clamped and fixed by the limited bicycle front fork 12 and the roller 40 after the welding part of the bicycle beam 13 contacts the welding part of the bicycle front fork 12.

[0036] At this time, the two third electric sliders 22 are started, and the two third electric sliders 22 move away from each other on the third guide rail 21, so that the two arc blocks 36 that clamp and fix the bicycle frame 13 can move away from each other, and the two arc blocks 36 can loosen the clamping of the bicycle frame 13.

[0037] At this time, the first electric slider 3 is started, and the first electric slider 3 drives the fixing plate 8 to move toward the bicycle beam 13, thereby making the two mounting blocks 29 move toward the bicycle front fork 12, and while the fixing plate 8 moves toward the bicycle beam 13, the fourth electric telescopic rod 39 is started, the piston rod of the fourth electric telescopic rod 39 is retracted, and the distance that the fixing plate 8 moves toward the bicycle beam 13 is equal to the distance that the piston rod of the fourth electric telescopic rod 39 is retracted, which can keep the roller 40 and the limited bicycle front fork 12 clamping and fixing the bicycle beam 13 while allowing the fixing plate 8 to move toward the bicycle beam 13, thereby making the two welding gun heads 31 move toward the welding position of the bicycle beam 13 and the bicycle front fork 12, until the two welding gun heads 31 reach the welding position of the bicycle beam 13 and the bicycle front fork 12 and stop, at this time, the third electric telescopic rod 38 is started, and the third electric telescopic rod 38 is retracted. The piston rod of the rod 38 pushes the connecting plate 28 to move closer to the bicycle beam 13, so that the connecting rod 27 pushes the limit frame 33 to move closer to the bicycle front fork 12, so that the angle of the welding gun head 31 can be changed, and then the angles of the two welding gun heads 31 can be adjusted at the same time. The adjustment of the angle of the welding gun head 31 can drive the angle of the arc block 36 to be adjusted, and the angles of the two arc blocks 36 can be adjusted to align with the welding position of the bicycle beam 13 and the bicycle front fork 12. At this time, the water pump in the first corrugated pipe is started, and the water pump draws water in the water tank 15 into the cavity in the arc block 36, and sprays it out through the air hole 37 to spray water to clean the welding position of the bicycle beam 13 and the bicycle front fork 12. The welding position of the bicycle beam 13 and the bicycle front fork 12 can be sprayed with water to clean, thereby ensuring the cleanliness of the welding position of the bicycle beam 13 and the bicycle front fork 12 and avoiding the presence of impurities that affect the welding effect.

[0038] After the welding parts of the bicycle frame 13 and the bicycle front fork 12 are cleaned by spraying water, the blowing function of the dual-purpose vacuum cleaner 17 is started, and the welding parts of the bicycle frame 13 and the bicycle front fork 12 can be blown dry by the air holes 37 to dry the water stains remaining in the welding parts, thereby ensuring the dryness of the welding parts.

[0039] After the welding part of the bicycle beam 13 and the bicycle front fork 12 is blown dry, the second electric telescopic rod 35 is started, and the piston rod of the second electric telescopic rod 35 pushes the arc block 36 to move closer to the welding part of the bicycle beam 13 and the bicycle front fork 12 until the arc block 36 outside the bicycle beam 13 contacts the joint between the outside of the bicycle beam 13 and the bicycle front fork 12 and stops, and the arc block 36 inside the bicycle beam 13 contacts the joint between the inside of the bicycle beam 13 and the bicycle front fork 12 and stops. At this time, the liquid pump in the second bellows is started, and the liquid pump can extract the flux in the flux box 16 into the cavity in the arc block 36 and flow out through the air hole 37, thereby welding the bicycle beam 13 and the bicycle front fork 12. The external joints and internal joints of the beam 13 and the bicycle front fork 12 are all coated with flux, and the second electric slider 19 is started. The second electric slider 19 moves on the annular second guide rail 18, so that the two arc blocks 36 can move along the external and internal joints of the bicycle beam 13 and the bicycle front fork 12, and at the same time, the roller 40 rolls along the cross section of the bicycle beam 13 to always keep the bicycle beam 13 clamped and fixed, so that the external and internal joints of the bicycle beam 13 and the bicycle front fork 12 can be coated with flux at one time, and the flux can be automatically coated on the external and internal joints of the bicycle beam 13 and the bicycle front fork 12 without manual coating of the flux.

[0040] After applying flux to the outer and inner joints of the bicycle frame 13 and the bicycle front fork 12, the two second electric telescopic rods 35 are started at the same time to make the two arc blocks 36 move away from each other until the distance between the two arc blocks 36 is greater than the distance between the two welding gun heads 31 and then stop. At this time, the piston rod of the fourth electric telescopic rod 39 can be used again to push the connecting plate 28 to move closer to the bicycle frame 13 to adjust the welding angles of the two welding gun heads 31. When the angle of one welding gun head 31 changes, the angle of the other welding gun head 31 also changes accordingly. The welding angles of the two welding gun heads 31 can be adjusted simultaneously at one time, and the welding angle of the welding gun head 31 located on the outside compared to the outer joint and the welding angle of the welding gun head 31 located on the inside compared to the inner joint can always remain consistent.

[0041] At this time, the two third electric slides 22 are started, and the two third electric slides 22 move toward each other on the third guide rail 21, thereby causing the two welding gun heads 31 to move toward each other until the two welding gun heads 31 reach the welding distance and stop.

[0042] At this time, the two welding gun heads 31 are started at the same time, and the welding gun head 31 located on the outside can weld the seam between the bicycle beam 13 and the outside of the bicycle front fork 12, and the welding gun head 31 located on the inside can weld the seam between the bicycle beam 13 and the inside of the bicycle front fork 12. It can weld the seam between the bicycle beam 13 and the outside of the bicycle front fork 12 while also welding the seam between the bicycle beam 13 and the inside of the bicycle front fork 12. Compared with traditional welding equipment that can only weld the seam between the bicycle beam 13 and the bicycle front fork 12, the present device can weld the seam between the bicycle beam 13 and the outside of the bicycle front fork 12 while also welding the seam between the bicycle beam 13 and the inside of the bicycle front fork 12, thereby doubling the welding firmness between the bicycle beam 13 and the bicycle front fork 12, ensuring the welding firmness between the bicycle beam 13 and the bicycle front fork 12, and avoiding the problem of easy fracture of the welding point between the bicycle beam 13 and the bicycle front fork 12.

[0043] While the two welding gun heads 31 are welding the outer seams and the inner seams of the bicycle beam 13 and the bicycle front fork 12 at the same time, the second electric slider 19 is started to move on the annular second guide rail 18. Since the annular second guide rail 18 is coaxial with the inner circle of the bicycle beam 13, the two welding gun heads 31 can move along the outer and inner seams of the bicycle beam 13 and the bicycle front fork 12, and the outer and inner seams of the bicycle beam 13 and the bicycle front fork 12 can be welded at one time. The welding of the outer and inner welds of the bicycle beam 13 and the bicycle front fork 12 can be completed without pausing, thereby avoiding the situation where traditional welding equipment has leaking welds due to welding pauses when welding the bicycle beam 13 and the bicycle front fork 12, ensuring the continuity when welding the outer and inner welds of the bicycle beam 13 and the bicycle front fork 12, and completing the welding process of the outer and inner welds of the bicycle beam 13 and the bicycle front fork 12 at one time, ensuring the welding efficiency of the bicycle beam 13 and the bicycle front fork 12.

[0044] After the welding of the outer and inner seams of the bicycle frame 13 and the bicycle front fork 12 is completed, the two third electric sliders 22 are started again at the same time, so that the two third electric sliders 22 move away from each other, and then the two welding gun heads 31 move away from each other, and the piston rod of the third electric telescopic rod 38 pushes the connecting plate 28 to adjust the angles of the two welding gun heads 31 again, and then the angles of the two arc blocks 36 are adjusted, and the two second electric telescopic rods 35 are started at the same time, so that the two arc blocks 36 move closer to each other, and then the two arc blocks 36 are respectively connected to the outer The second electric slider 19 is started to move on the annular second guide rail 18, so that the two arc blocks 36 can grind the welds on the outside and inside of the bicycle frame 13 and the bicycle front fork 12, and the slag of the welds can be removed by grinding to ensure the smoothness and aesthetics of the welds. While the arc blocks 36 are grinding the welds, the dust suction function of the blowing and suction dual-purpose vacuum cleaner 17 is started, and the dust generated by the arc blocks 36 when grinding the welds can be adsorbed through the air holes 37, so as to prevent the dust generated by the arc blocks 36 when grinding the welds from affecting the surrounding environment.

[0045] After the grinding of the external and internal welds of the bicycle beam 13 and the bicycle front fork 12 is completed, the first electric slider 3 is started to make the fixing plate 8 move away from the bicycle beam 13 until the two arc blocks 36 move to the edge of the bicycle beam 13 and then stop, and the two arc blocks 36 are used again to clamp and fix the bicycle beam 13. The two arc blocks 36 can be used to clamp and fix the edge of the bicycle beam 13, and the fourth electric telescopic rod 39 is started first to make the roller 40 break away from the contact with the bicycle beam 13, and then the first electric telescopic rod 7 is started, and the piston rod of the first electric telescopic rod 7 pushes the fixing plate 8 to move upward, thereby making the welded bicycle beam 13 and the bicycle front fork 12 move upward, and then the bicycle front fork 12 moves out of the limit groove 14, and then the motor 5 is started, and the output shaft of the motor 5 drives the mounting plate 6 to rotate to make the first electric telescopic rod 7 The bicycle beam 13 and the bicycle front fork 12 are clamped and fixed by the two arc blocks 36, and rotate until the bicycle beam 13 and the bicycle front fork 12 rotate to the top of the blanking box 11 and then stop. The first electric slider 3 is used to move on the first guide rail 2 again, and the bicycle beam 13 and the bicycle front fork 12 clamped and fixed by the two arc blocks 36 can be moved to the top of the blanking box 11. At this time, the two third electric sliders 22 are started at the same time. The two third electric sliders 22 move away from each other to make the two arc blocks 36 move away from each other, so that the two arc blocks 36 loosen the clamping and fixing of the bicycle beam 13. At this time, the bicycle beam 13 and the bicycle front fork 12 can fall into the blanking box 11, and the blanking processing of the welded bicycle beam 13 and the bicycle front fork 12 can be automatically completed, thereby improving the degree of automation of the device when in use.
