Since the existing welding tooling must cut the process relief groove during production, the mounting hole of the screw seat is easy to be stuck in the process relief groove during actual use, resulting in the eccentric tilt of the welding tooling, which in turn leads to the screw seat and the screw seat The mounting holes are not concentric
In addition, the matching part of the existing welding tool and the oil pan wears a lot during use, which is prone to wear and cause the positioning gap to be too large. The deformed welding tool will also cause the screw seat and the screw seat mounting hole to be out of concentricity during positioning welding. The welded screw seat and the screw seat mounting hole are not concentric, resulting in the interference of the screw seat installation hole when the oil drain plug is assembled with the screw seat, causing the screw plug support surface and the corresponding oil pan after the oil drain plug is assembled The planes are not parallel, oil leakage occurs

Embodiment Construction
[0028] The oil pan is the lower half of the crankcase, also known as the lower crankcase. There is also an oil drain plug at the bottom of the oil pan. The oil drain screw plug passes through the screw seat mounting hole of the oil pan and is fixed with the screw seat inside the oil pan. The screw seat is welded on the oil pan and communicates with the mounting hole of the screw seat. The welding quality of the screw seat will directly affect the sealing degree and service life of the oil pan. When the screw seat and the oil pan are welded, a welding tool is generally used for positioning welding to ensure the concentricity of the screw seat and the mounting hole of the screw seat.
[0029] However, after long-term research by researchers, it has been found that the existing welding tooling must have a cutting process relief groove during production. In actual use, the mounting hole of the screw seat is easily stuck in the process relief groove, causing the welding tooling to...

The invention provides a screw seat welding positioning tooling, and relates to the field of a welding accessory. The screw seat welding positioning tooling comprises a screw seat fixing head, a positioning ring and a cylindrical base, wherein the side surface of the base is provided with a cut convenient to be clamped by a clamp, one end of the base is provided with a lug boss, the screw seat fixing head is provided with screw threads matched with the screw seat, the screw seat fixing head is connected with one end, provided with the lug boss, of the base, and the positioning ring is clamped and arranged between the screw seat fixing head and the lug boss, and is a hard alloy positioning ring. The screw seat welding positioning tooling provided by the invention has the advantages that the positioning precision and the service life of the screw seat welding positioning tooling are respectively improved and prolonged, further, the concentric error of the screw seat and a screw seat installing hole is reduced, and the problem of oil bottom case oil leakage accidents due to welding decentraction of the screw seat and the screw seat installing hole is thoroughly solved.
Description
technical field [0001] The invention relates to the field of welding accessories, in particular to a screw seat welding positioning tool. Background technique [0002] The oil pan is the lower half of the crankcase, also known as the lower crankcase. The function is to close the crankcase as the shell of the oil storage tank, prevent impurities from entering, collect and store the lubricating oil flowing back, dissipate part of the heat of the lubricating oil, and prevent the lubricating oil from oxidation. There is also an oil drain plug at the bottom of the oil pan. The oil drain screw plug passes through the screw seat mounting hole of the oil pan and is fixed with the screw seat inside the oil pan. The screw seat is welded on the oil pan and communicates with the mounting hole of the screw seat. The welding quality of the screw seat will directly affect the sealing degree and service life of the oil pan. [0003] When the screw seat and the oil pan are welded, a weldi...
