[0002] Existing oil cup welding machines are equipped with special fixtures or clamping mechanisms for fixing the various components of the oil cup. These fixtures can accurately position and clamp the different components of the oil cup, ensuring that the different components of the oil cup are kept in a relatively accurate position during welding.

This results in poor welding quality, unsightly welds, and a high scrap rate. Furthermore, there are difficulties in removing the oil cups after welding, as well as deformation of the overlapping structure of the oil cup side walls. These issues fail to meet normal welding production processes, leading to a large number of defective products during the welding process. Utility Model Content

[0024] Figure 3 This is a partial structural schematic diagram of the fixing device according to the present disclosure. Detailed Implementation
[0025] The technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.
[0026] like Figure 1-3 As shown, this embodiment of the present disclosure provides a fixing device for welding oil cups. The fixing device provided in this embodiment is particularly suitable for elongated oil cups 1, which have a bottom wall 11, two side walls 12 located on both sides of the oil cup 1, and two end walls 13 located at both ends of the oil cup 1. The bottom wall 11, the two side walls 12, and the two end walls 13 enclose a receiving groove for receiving oil. The sidewall 12 is substantially perpendicular to the bottom wall 11. Both ends of the sidewall 12 are connected to the end wall 13. One side of the sidewall 12 is connected to the bottom wall 11, and the other side is provided with a folded edge structure 14. The length of the folded edge structure 14 is more than 80% of the length of the other side, for example, 85%, 90%, 95%, 97%, or 100%. The folded edge structure 14 is a structure in which the outer edge area of the sidewall 12 at the other side is close to or substantially in contact with the adjacent area. It is formed by bending the outer edge area of the sidewall 12 at the other side towards the adjacent area, so that the outer edge area is close to or substantially in contact with the adjacent area. The folded edge structure 14 provides a relatively smooth side structure for the sidewall 12, avoiding damage to the user from the side of the sidewall 12. Optionally, the end wall 13 includes an arc-shaped wall 131 and a planar wall 132 connected to each other. One end of the arc-shaped wall 131 is connected to the bottom wall 11, and the other end is connected to the planar wall 132. The planar walls 132 of the two end walls 13 are arranged opposite to each other, and the arc-shaped wall 131 smoothly transitions from the plane of the bottom wall 11 to the plane of the planar wall 132. The arc-shaped wall 131 is preferably configured as a circular arc-shaped wall.
[0027] The fixing device includes a support body, which can be configured as a frame or a support base plate. For example... Figure 2 As shown, the support body is provided with at least one fixing structure, such as two, three or four fixing structures, which are used to fix and position the oil cup 1.
[0028] like Figure 2 , Figure 3As shown, the fixing structure includes a fixed support 31, a movable support 32, a first movable clamping body 33, and a second movable clamping body 34. Both the fixed support 31 and the movable support 32 support the inner surface of one end wall 13 of the oil cup 1. Specifically, the inner surface of one end wall 13 of the oil cup 1 abuts against the fixed support 31 and the movable support 32, respectively, and the one end wall 13 is supported by the fixed support 31 and the movable support 32. Meanwhile, the fixed support 31 is also used to position one side wall 12 by abutting against the inner surface of one side wall 12 of the oil cup 1, and the movable support 32 is also used to position the other side wall 12 by abutting against the inner surface of the other side wall 12 of the oil cup 1; thus, by the fixed support 31 and the movable support 32 abutting against the inner surfaces of the two side walls 12 of the oil cup 1 respectively, the positioning of the two side walls 12 of the oil cup is realized, especially the positioning of the oil cup in the direction perpendicular to the side wall 12, and the fixed support 31 and the movable support 32 can also fix the oil cup to a certain extent.
[0029] The movable support 32 can move along a preset direction so that it is located in one of a preset position and a non-preset position. When the movable support 32 is located in the preset position, it can abut against the inner surface of the other side wall 12 of the oil cup 1, thereby positioning the other side wall 12. When the movable support 32 is located in the non-preset position, it does not abut against the inner surface of the other side wall 12 of the oil cup 1, which is beneficial for feeding the oil cup 1 to be welded and removing the welded oil cup 1 from the fixing device. The distance between the overlapping edge structures 14 on the two sides of the oil cup 1 is smaller than the distance between other positions between the two sides. The movable support 32 can also prevent the fixed support 31 and / or the movable support 32 from squeezing the overlapping edge structure 14 on the side of the oil cup 1 during the removal of the welded oil cup 1, thus avoiding deformation of the overlapping edge structure.
[0030] The first movable clamping body 33 is used to cooperate with the fixed support body 31 to clamp one side wall 12 of the oil cup 1. Specifically, the first movable clamping body 33 can cooperate with the fixed support body 31 to clamp one side wall 12 of the oil cup 1 by abutting against the outer surface of the side wall 12 of the oil cup 1 opposite to the fixed support body 31, and the side wall 12 of the oil cup 1 is clamped between the fixed support body 31 and the first movable clamping body 33.
[0031] The second movable clamping body 34 is used to cooperate with the movable support body 32 to clamp the other side wall 12 of the oil cup 1. Specifically, the second movable clamping body 34 can cooperate with the movable support body 32 to clamp the other side wall 12 of the oil cup 1 by abutting against the outer surface of the other side wall 12 of the oil cup 1 opposite to the movable support body 32, and the other side wall 12 of the oil cup 1 is clamped between the movable support body 32 and the second movable clamping body 34.
[0032] Therefore, the fixing device provided in this embodiment positions and fixes the oil cup 1 through the fixed support 31, the movable support 32, the first movable clamping body 33 and the second movable clamping body 34, and the movable support 32 prevents the overlapping structure on the side of the oil cup 1 from being squeezed and deformed by the fixed support 31 and / or the movable support 32 during the process of removing the welded oil cup 1 from the fixing device.
[0033] In an optional embodiment, the fixing structure further includes a third movable clamping body 35.

The fixing support body 31 has a first supporting curved surface adapted to the inner surface of the end wall 13 of one end of the oil cup 1. The fixing support body 31 fits against the curved inner surface of the end wall 13 of one end through the first supporting curved surface. The third movable clamping body 35 is used to clamp one end wall 13 of the oil cup 1 through the clamping curved surface cooperating with the first supporting curved surface of the fixing support body 31, thereby positioning and fixing the oil cup 1.
