Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery production, in particular to an agricultural machinery frame welding auxiliary support device. Background Art

[0002] Agricultural machinery refers to various machines used in the production process of crop planting and animal husbandry, as well as in the primary processing and treatment of agricultural and livestock products. Agricultural machinery plays an important role in modern agricultural production. Their use can improve production efficiency, reduce labor costs, and promote the development of agricultural modernization.

[0003] In agricultural machinery, some equipment frames are welded from square steel and other components. During the welding process, square tubes are generally placed on a workbench. The welded square tubes lack necessary support, which is not only not conducive to welding work, but also causes workers to frequently adjust the workpiece according to the welding position. Therefore, auxiliary support equipment is needed to effectively support the welded square tubes to facilitate welding work. Utility Model Content

[0026] Specifically, the locking mechanism 5 includes a mounting seat 51, a top block 52 and an adjusting knob 53. The mounting seat 51 is fixedly arranged on the outside of the intubation seat 1, the top block 52 is clamped on the inner side of the top of the mounting seat 51, the adjusting knob 53 is connected to the bottom of the mounting seat 51 by a thread, the top of the adjusting knob 53 is movably connected to the bottom of the top block 52, the outer edge of the turntable 42 is provided with a limit tooth, the top of the top block 52 is provided with a tooth groove that cooperates with the limit tooth on the outer edge of the turntable 42, and the surface of the support rod 45 is provided with a groove that cooperates with the screw 4 3, one end of the connecting shaft 46 passes through and extends to the outside of one side of the support rod 45, the surface of the connecting shaft 46 is provided with a thread, which is connected to the clamping knob 48 by a thread, the inner side of the clamping knob 48 is in close contact with the outer surface of the support rod 45, the intubation seat 1 includes a bottom base and a top intubation, the square tube 2 is clamped in the top intubation of the intubation seat 1, the top inclined surface of the wedge block 3 is in contact with the inner side of the top of the intubation, the top outer side of the wedge block 3 is provided with a groove, and one end of the limit block 49 is arranged to be inclined downward.

[0027] In this embodiment, when in use, the square tube 2 that needs to be welded is first fixed, and the wedge block 3 is inserted into the top tube of the tube holder 1 after the horizontal side thereof is fitted against the square tube 2. After the inclined surface on one side of the wedge block 3 contacts the inner side of the top of the tube, the square tube 2 is prevented from continuing to fall under the action of gravity, pressure and friction, so that the square tube 2 is vertically fixed on the inner side of the top of the tube holder 1. Subsequently, the rotation angle of the turntable 42 is adjusted to change the inclination angle of the support rod 45. After the adjusting knob 53 is rotated until the tooth groove at the top of the top block 52 is separated from the latch teeth on the surface of the turntable 42, the turntable 42 can be freely rotated around the latch shaft 41. After adjusting to the appropriate angle, the adjusting knob 53 is rotated to raise the top block 52 so that the tooth groove at its top engages with the latch teeth on the surface of the turntable 42 to achieve a fixing effect.

[0028] Furthermore, after loosening the locking knob 44, the position of the support rod 45 can be adjusted on the surface of the screw rod 43 to change the support position and support height. After adjusting the angle of the support rod 45, the height and left and right position of the support bracket 47 at its end can be adjusted. Two screw rods 43 are provided on the surface of the turntable 42 to ensure that after rotating the locking knob 44, the support rod 45 can be better fixed. Further, the clamping knob 48 is rotated to loosen the threaded end at the end of the connecting shaft 46, so that the angle of the support bracket 47 can be adjusted, thereby changing the welding angle. After tightening the clamping knob 48, the support rod 45 is clamped by the clamping knob 48 and the shoulder of the connecting shaft 46 to achieve a fixing effect. In this way, after the connecting pipe to be welded is placed in the top slot of the support bracket 47, it will be guided and squeezed by the limit block 49 to be centered, so that the part to be welded is in contact with the square tube 2 fixed in the tube seat 1, which is convenient for welding. A slot is provided on the outer side of the wedge block 3, and the rope is clamped in the slot and pulled out upward to facilitate the disassembly of the square tube 2.
