Description

Technical Field

[0001] This utility model relates to the field of workpiece welding technology, and in particular to a welding fixture for an automotive oil pan. Background Technology

[0002] In the automotive manufacturing industry, the diesel engine oil pan is a key component of the engine, and its welding quality directly affects the engine's performance and reliability.

[0003] Currently, in the traditional diesel engine oil pan welding process, there is a lack of specialized and precise positioning and fixing devices. The oil pan and accessories are mainly placed and fixed by the operator's experience and manual operation.

[0004] The above-mentioned existing technical solutions have the following defects: due to the lack of a precise limiting structure, the diesel engine oil pan is difficult to stabilize on the welding platform and is prone to displacement during the welding process. Furthermore, for various accessories that need to be welded on the diesel engine oil pan, there is a lack of effective limiting devices, and the accessories are prone to shaking or displacement during welding. Utility Model Content

[0005] The purpose of this invention is to provide a welding fixture for automotive oil pans to solve the problems existing in the prior art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A welding fixture for an automotive oil pan includes a base plate, an upward limiting edge extending from the left side of the base plate, a limiting unit provided at the top of the limiting edge, the limiting unit and the limiting edge both being used to limit the diesel engine oil pan, a clamping unit provided at the front right end of the base plate, the clamping unit being used to limit the oil pan, and a support frame fixedly installed at the rear left end of the base plate.

[0008] By adopting the above technical solution, the diesel engine oil pan to be welded is placed on the base plate. The limiting edge limits the bottom rear end of the diesel engine oil pan, the limiting unit limits the top rear end of the diesel engine oil pan, and the clamping unit limits the front side of the diesel engine oil pan while clamping the first component on the oil pan, making it easier for workers to weld the first component onto the diesel engine oil pan. The support frame is used to support the second component on the oil pan, making it easier for workers to weld the second component onto the oil pan, thus effectively ensuring the accuracy and quality of the welding.

[0009] In a further embodiment, the limiting unit includes a vertical plate and a horizontal plate, the vertical plate being fixedly installed on the top of the limiting edge, and the horizontal plate being fixedly installed on the top of the vertical plate.

[0010] By adopting the above technical solution, the vertical plate supports the horizontal plate, enabling the horizontal plate to limit the top of the diesel engine oil pan.

[0011] In a further embodiment, a fixing plate is fixedly mounted on the right end of the substrate.

[0012] By adopting the above technical solution, since the diesel engine oil pan has a structure that is completely open at the bottom and is divided into a first chamber and a second chamber by a partition, the fixing plate limits the diesel engine oil pan again by resisting the partition, thereby improving the welding quality.

[0013] In a further embodiment, the support frame includes a first ear plate, a second ear plate, and a connecting rod. The connecting rod is L-shaped, with one end fixedly installed on the rear side of the base plate and the other end fixedly installed on the right side of the first ear plate. The first ear plate and the second ear plate are arranged vertically, with the first ear plate fixedly installed on the right side of the second ear plate in a vertical direction. The front portions of the first ear plate and the second ear plate are coplanar, and an anti-slip plate is fixedly installed on the top of the second ear plate.

[0014] By adopting the above technical solution, one end of the second component is movably installed in the diesel engine oil pan, and the other end of the second component is placed on the second ear plate. The anti-slip plate placed on the second ear plate is to prevent the second welding plate from sliding during the welding process, and the operator no longer needs to support it during the welding process.

[0015] In a further embodiment, the clamping unit includes a vertical plate and a baffle. The top of the vertical plate is provided with a downward semi-circular groove, and the bottom of the vertical plate is provided with an integrally formed extension plate. The baffle is fixedly installed on the top of the extension plate, and the side of the extension plate near the vertical plate is provided with a circular groove.

[0016] By adopting the above technical solution, one end of the first component is snapped into the diesel engine oil pan, and the other end of the first component passes through the semi-circular groove and is snapped into the circular groove, thereby limiting the first component and accurately welding the first component onto the diesel engine oil pan.

[0017] In a further embodiment, the top of the substrate is provided with a plurality of through holes that run vertically from left to right at equal intervals.

[0018] By adopting the above technical solution, the through holes evenly spaced at the top of the substrate can facilitate the discharge of debris from the diesel engine oil pan when necessary.

[0019] In summary, this utility model has the following beneficial effects:

[0020] 1. By placing the diesel engine oil pan to be welded on the base plate, the limiting edge limits the bottom rear end of the diesel engine oil pan, the limiting unit limits the top rear end of the diesel engine oil pan, and the clamping unit limits the front side of the diesel engine oil pan while clamping the first component on the oil pan, making it easier for workers to weld the first component onto the diesel engine oil pan. The support frame is used to support the second component on the oil pan, making it easier for workers to weld the second component onto the oil pan. This effectively ensures the accuracy and quality of the welding. Attached Figure Description

[0027] Example 1:

[0028] like Figures 1-3As shown, a welding fixture for an automotive oil pan includes a base plate 1. An upward limiting edge 2 extends from the left side of the base plate 1. A limiting unit 3 is provided at the top of the limiting edge 2. The limiting unit 3 and the limiting edge 2 are used to limit the diesel engine oil pan. A clamping unit 4 is provided at the front right end of the base plate 1. The clamping unit 4 is used to limit the diesel engine oil pan. A support frame 5 is fixedly installed at the rear left end of the base plate 1.

[0029] The limiting unit 3 includes a vertical plate 31 and a horizontal plate 32. The vertical plate 31 is fixedly installed on the top of the limiting edge 2, and the horizontal plate 32 is fixedly installed on the top of the vertical plate 31. A fixing plate 6 is fixedly installed on the right end of the base plate 1. The support frame 5 includes a first ear plate 51, a second ear plate 52, and a connecting rod 53. The connecting rod 53 is L-shaped. One end of the connecting rod 53 is fixedly installed on the rear side of the base plate 1, and the other end is fixedly installed on the right side of the first ear plate 51. The first ear plate 51 and the second ear plate 52 are arranged vertically. The first ear plate 51 is vertically aligned with the base plate 1. The first ear plate 51 and the second ear plate 52 are coplanar at the front. The anti-slip plate 7 is fixedly installed on the top of the second ear plate 52. The clamping unit 4 includes a vertical plate 41 and a baffle 42. The top of the vertical plate 41 is provided with a downward semi-circular groove. The bottom of the vertical plate 41 is provided with an integrally formed extension plate. The baffle 42 is fixedly installed on the top of the extension plate. The side of the extension plate near the vertical plate 41 is provided with a circular groove. The top of the base plate 1 is provided with multiple through holes that pass through vertically from left to right at equal intervals.

[0030] Specific implementation process: Before welding begins, the worker places the diesel engine oil pan to be welded on the base plate 1. At this time, the fixing plate 6 at the right end of the base plate 1 initially limits the diesel engine oil pan by abutting against the partition inside the oil pan. Then, the limiting edge 2 extending upward from the left side of the base plate 1 further limits the bottom rear end of the diesel engine oil pan. Then, because the vertical plate 31 of the limiting unit 3 is fixed to the top of the limiting edge 2, and the horizontal plate 32 is fixedly installed on the top of the vertical plate 31, it can limit the top rear end of the diesel engine oil pan, ensuring that the diesel engine oil pan is accurately and stably positioned on the base plate. Subsequently, the front limiting of the diesel engine oil pan is handled by the clamping unit 4 at the right front end of the base plate 1. The semi-circular groove on the plate and the circular groove on the extension plate cooperate with each other. One end of the first component is inserted into the diesel engine oil pan. The operator passes the other end of the first component through the semi-circular groove and inserts it into the circular groove of the baffle 42 to accurately position the first component. Then the operator performs the welding work here. For the second component inside the diesel engine oil pan, the support frame 5 on the rear left side of the base plate 1 plays a role. The L-shaped connecting rod 53 of the support frame 5 supports the first ear plate 51 and the second ear plate 52. One end of the second component is movably installed in the diesel engine oil pan, and the other end is placed on the anti-slip plate 7 on the top of the second ear plate 52. The anti-slip plate 7 effectively prevents the second component from sliding during welding without the need for additional support from the operator. Finally, the operator performs the welding work here.

[0031] In the embodiments disclosed in this utility model, the terms "installation," "connection," "linking," and "fixing" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; "linking" can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments disclosed in this utility model according to the specific circumstances.

[0032] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
