[0012] The present invention will now be further described with reference to the accompanying drawings.

[0013] like Figures 1 to 8 As shown, a welding and fixing device for an agricultural machinery steering bracket includes a base plate fixing device 3, a first shaft fixing device 4, a second shaft fixing device 5, a second magnet 6, and a connecting plate fixing device 7. The base plate fixing device 3 is used to fix the steering base plate 11; the first shaft fixing device 4 is located at one end of the base plate fixing device 3 and is used to fix the steering shaft 12; the second shaft fixing device 5 is located on one side of the base plate fixing device 3 and is used to fix the steering linkage 13; the second magnet 6 is installed on the second shaft fixing device 5 and is used to fix the positioning ring 15; the connecting plate fixing device 7 is installed on one side of the second shaft fixing device 5 and is used to fix the steering connecting plate 14.

[0014] The steering base plate 11 is fixed by the base plate fixing device 3. Then, the steering shaft 12, steering linkage 13, positioning ring 15 and steering connecting plate 14 are fixed around the steering base plate 11 by the first shaft fixing device 4, the second shaft fixing device 5, the second magnet 6 and the connecting plate fixing device 7. This allows all parts to be fixed in one clamping, and then welding can be carried out without interference. This greatly improves the overall efficiency, ensures the welding accuracy, improves the consistency of the product and reduces the cost.

[0015] The base plate fixing device 3 includes a fixed base 31, a first positioning pin 32, a second positioning pin 33, a base plate clamping cylinder 33, and a base plate clamping rod 34. The fixed base 31 is mounted on the welded base plate 2. The first positioning pin 32 and the second positioning pin 33 are both fixed to the top of the fixed base 31 and are respectively inserted into the first shaft hole 111 and the second shaft hole 112 of the steering base plate 11. The base plate clamping cylinder 33 is mounted on the welded base plate 2 and is rotatably connected to the base plate clamping rod 34. The base plate clamping rod 34 is rotatably mounted on the welded base plate 2 through a connecting rod assembly, which can increase the clamping force of the base plate clamping rod 34. The base plate clamping cylinder 33 clamps the steering base plate 11 onto the fixed base 31 through the base plate clamping rod 34. The base plate clamping cylinder 33 is rotatably connected to one end of the base plate clamping rod 34 through a U-shaped connector 35. The linkage assembly includes a linkage seat 361, a first pin 362, a second pin 363, and a linkage rod 364. The linkage seat 361 is fixed to the welded base plate 2. The first pin 362 is fixed to the top of the linkage seat 361 and is rotatably connected to one end of the linkage rod 364. The other end of the linkage rod 364 is rotatably connected to the base plate clamping rod 34 via the second pin 363. The first positioning pin 32 and the second positioning pin 33 achieve complete positioning of the steering base plate 11 with high positioning accuracy. Then, the base plate clamping cylinder 33 and the base plate clamping rod 34 are used to fix the steering base plate 11, making the assembly and disassembly of the steering base plate 11 convenient. To further facilitate the insertion of the steering base plate 11 into the first positioning pin 32, reduce the difficulty of inserting the steering base plate 11, and minimize the difficulty of inserting the first positioning pin 32 and the second positioning pin 33 into the first shaft hole 111 and the second shaft hole 112 simultaneously due to machining errors, the first positioning pin 32 is provided with several cut surfaces 321 in a circular array on its side. The cut surfaces 321 reduce the contact area between the first positioning pin 32 and the first shaft hole 111, increasing the fault tolerance, while not affecting the positioning accuracy.

[0016] To facilitate the rapid fixing of the steering shaft 12, the first shaft fixing device 4 includes a first fixing seat 41, a first fixing pin 42, and a first rotary clamping cylinder 43. The first fixing seat 41 is installed at one end of the fixed base 31. The center of the first fixing seat 41 is provided with a first fixing groove 411, which is a V-shaped groove. The V-shaped groove facilitates the positioning of shaft parts and provides high positioning accuracy. The first fixing pin 42 is fixed to the bottom of the first fixing groove 411 and is located at the center of the first fixing groove 411. The first fixing pin 42 is used to insert into the first connecting hole 121 of the steering shaft 12, thereby achieving radial positioning of the steering shaft 12. The first rotary clamping cylinder 43 is fixed on the welded base plate 2 and is located at one end of the first fixing seat 41. The first rotary clamping cylinder 43 is arranged opposite to the first fixing groove 411. The first rotary clamping cylinder 43 is used to press the steering shaft 12 into the first fixing groove 411, thereby fixing the steering shaft 12 and pressing the steering shaft 12 onto the steering base plate 11. Since the first rotary clamping cylinder 43 is fixed from the end of the steering shaft 12, it does not interfere with the welding between the steering shaft 12 and the steering base plate 11, making welding convenient and ensuring welding accuracy.

[0017] To achieve precise positioning and fixation of the steering link 13, the second shaft fixing device 5 includes a second fixing seat 51 and a second rotary clamping cylinder 52. The second fixing seat 51 is fixed to the welded base plate 2, and the top of the second fixing seat 51 is provided with a second fixing groove 511, which is a V-shaped groove. The second rotary clamping cylinder 52 is fixed to the welded base plate 2 and is also located at one end of the second fixing seat 51, opposite to the second fixing groove 511. The second rotary clamping cylinder 52 is used to press the steering link 13 into the second fixing groove 511. The second fixing seat 51 is also located on one side of the fixing base 31, so that the L-shaped steering link 13 can be accurately inserted into the steering base plate 11.

[0018] The second magnet 6 is fixed to one end of the second fixed base 51. The second magnet 6 attracts the positioning ring 15 to the end of the second fixed base 51, thereby fixing the position of the positioning ring 15. This facilitates welding the positioning ring 15 to the steering linkage 13 and simplifies the fixing and positioning of the positioning ring 15. To improve the reliability of the positioning of the positioning ring 15, the second magnet 6 is symmetrically arranged on both sides of the second fixed groove 511.

[0019] To facilitate the quick fixing and disassembly of the steering plate 14, the plate fixing device 7 includes a third base 71, a third fixing seat 72, a third positioning seat 73, a third magnet 74, a third baffle 75, and a third rotary clamping cylinder 76. The third base 71 is mounted on the welding base plate 2 and is located on one side of the fixing base 31. There are two third fixing seats 72. The third fixing seats 72 and the third positioning seats 73 are installed on the third base 71 in sequence and on the same horizontal plane. The bottom of the third fixing seat 72 is provided with a first baffle 721, the bottom of the third positioning seat 73 is provided with a second baffle 731, and one end of the third positioning seat 73 is provided with a third baffle 75. The third rotary clamping cylinder 76 is fixed to one end of the third base 71. The third rotary clamping cylinder 76 is horizontally arranged and is arranged opposite to the third positioning seat 73. It is used to fix the steering plate 14 on the third positioning seat 73 and the third fixing seat 72. One end of the steering plate 14 rests against the third baffle 75, and one side of the steering plate 14 rests against the first baffle 721 and the second baffle 731. The third baffle 75, the second baffle 731 and the first baffle 721 achieve precise positioning of the steering plate 14, while the third magnet 74 facilitates the initial positioning of the steering plate 14 and prevents the steering plate 14 from falling before the third rotary clamping cylinder 76 is activated. The third rotary clamping cylinder 76 presses the steering plate 14 against the third fixed seat 72 and the third positioning seat 73, and makes the other end of the steering plate 14 rest against the steering linkage 13, which facilitates welding.

[0020] During operation, firstly, insert the first shaft hole 111 and the second shaft hole 112 of the steering base plate 11 into the first positioning pin 32 and the second positioning pin 33. Then, activate the base plate clamping cylinder 33, which clamps the steering base plate 11 onto the fixed base 31 via the base plate clamping rod 34. Next, place the steering shaft 12 into the first fixing groove 411 of the first fixed seat 41, ensuring that the first connecting hole 121 of the steering shaft 12 is inserted into the first fixing pin 42. Activate the first rotating clamping cylinder 43 to fix the steering shaft 12 into the first fixing groove 411, and insert the other end of the steering shaft 12 into the steering base plate 11. Then... The steering plate 14 is placed on the third fixed seat 72 and the third positioning seat 73. The end of the steering plate 14 abuts against the third baffle 75, and one side of the steering plate 14 abuts against the first baffle 721 and the second baffle 731. The steering plate 14 is pressed against the third fixed seat 72 and the third positioning seat 73 by the third rotary clamping cylinder 76. Finally, the steering link 13 is inserted into the steering base plate 11, and one end of the steering link 13 is inserted into the second fixing groove 511 of the second fixed seat 51, and the other end abuts against the steering plate 14. The second rotary clamping cylinder 52 is activated to fix the steering link 13 in the second fixing groove 511.

[0021] After welding is completed, loosen the base plate clamping cylinder 33, the first rotary clamping cylinder 43, the second rotary clamping cylinder 52 and the third rotary clamping cylinder 76, and remove the steering bracket.
