[0002] The existing three -way catalytic converter assembly, such as Figure 1 As shown in the drawing, after laser marking two -dimensional code to form two -dimensional code identification 102 on its cylinder body 101, the cylinder body and end cover still need to be welded, and the fixed hole left on the cylinder body is welded with a nut, which is used to install a sensor and a differential pressure pipe; Meanwhile, a small bracket needs to be welded on the identification position, which is used to install a heat shield; The subsequent several weldings are more likely to produce welding slag splashing on the two -dimensional code identification during the welding process of the welding gun, which can easily damage the two -dimensional code, thereby causing the two -dimensional code identification to be unable to be scanned and recognized. Therefore, in order to prevent the two -dimensional code identification from being splashed by welding slag, the current welding tool is designed with a blocking block 103 that blocks the two -dimensional code identification, the blocking block plate is an arc plate, the lower side of the arc plate is provided with a fixed part 103-1, and the fixed part is connected and fixed with the supporting column of the welding tool; The arc plate blocks the two -dimensional code identification surface of the cylinder body, the blocking block cannot be tightly combined with the cylinder body, and the gap between the blocking block becomes larger and larger with the collision of the welding tool in the use, the shielding effect of the welding slag is greatly reduced, and the welding slag is easily splashed on the two -dimensional code identification, which increases the product repair cost and reduces the production efficiency. CONTENT OF THE UTILITY MODEL

[0005] In the technical scheme of the above -mentioned three -way catalytic converter assembly identification anti -welding slag splashing tool, the more specific technical scheme can be: the size of the pressing surface of the blocking block is greater than the size of the two -dimensional code identification frame on the surface of the three -way catalytic converter cylinder.
[0006] In some possible implementation forms, two through holes are arranged radially and side by side at the end of the upper support arm, a shaft sleeve is arranged in the through holes, and the fastener is connected with the stop block through the shaft sleeve.
[0007] In some possible implementation forms, the fastener is an internal hexagonal socket screw.
[0008] In some possible implementation forms, the upper support arm and the lower support arm are arranged at an angle, and the upper support arm and the lower support arm are connected through a screw.
[0009] Compared with the prior art, the utility model has the following beneficial effects:
[0010] Since the support arm is used to fix the stop block, and the spring is arranged between the stop block and the support arm, the stop block can tightly adhere to the two-dimensional code mark on the surface of the cylinder through the expansion of the spring, and the splashed welding slag can be well blocked from splashing onto the two-dimensional code mark, the slag blocking effect is good, the product repair cost is reduced, the production efficiency is improved, and the comprehensive cost is reduced.

[0017] In order to make the above-mentioned purposes, features and advantages of the utility model more easily understood, the technical solutions in the utility model embodiments will be clearly and completely described below in conjunction with the drawings in the utility model embodiments. In the following description, a large number of specific details are set forth in order to fully understand the utility model, but the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the utility model, therefore, the utility model is not limited by the specific embodiments disclosed below.
[0018] In the description of the present invention, it should be understood that the terms "middle", "length", "width", "upper", "lower", "front", "back", "top", "bottom", "inside", "outside", "radial", "circumferential", etc., indicating the orientation or position relationship, are the orientation or position relationship shown in the accompanying drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the position or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention.
[0019] like Figures 2-4 The three-way catalytic converter assembly identification anti-welding slag splash tool shown in the figure includes a support column 1, a support arm is provided on the upper part of the support column 1, one end of the lower support arm 2 of the support arm is connected to the support column obliquely, and the other end of the lower support arm 2 is connected to the upper support arm 3 of the support arm, the upper support arm 3 is arranged obliquely upward, and the upper support arm 3 and the lower support arm 2 are connected by a screw 9; the end of the upper support arm 3 is installed with a stopper 6 for crimping the QR code logo 5 engraved on the three-way catalytic converter cylinder 4 through a fastener, and the fastener of this embodiment is a hexagon socket screw 8; the stopper 6 The crimping surface facing the three-way catalytic converter cylinder 4 is adapted to the shape of the crimped portion of the three-way catalytic converter cylinder 4; a compression spring 7 is sleeved on the fastener section between the upper support arm 3 and the stopper 6, one end of the compression spring is in contact with the upper support arm 3, and the other end is in contact with the stopper 6. When the compression spring is extended, it pushes the stopper forward, so that the stopper is always tightly pressed against the surface of the three-way catalytic converter cylinder 4. Even if the welding tooling is deformed by collisions during repeated use, the spring of this protective tooling can still push the stopper against the three-way catalytic converter cylinder 4, tightly protecting the QR code logo, and achieving good protective effect. Two through holes are radially arranged side by side at the end of the upper support arm 3, and a shaft sleeve 10 is placed in the through hole. The hexagon socket head screw 8 is inserted through the shaft sleeve 10 and connected to the stopper 6. The addition of the shaft sleeve can reduce the friction and wear between the hexagon socket head screw 8 and the hole, thereby protecting the hexagon socket head screw 8 and the hole.
[0020] The crimping surface size of the stopper 6 is larger than the frame size of the QR code mark 5 on the cylinder surface of the three-way catalytic converter. This setting enables the stopper to completely cover the QR code mark and effectively prevent the splashing welding slag from splashing onto the QR code mark.
