Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of DPF assembly, in particular to an engine DPF angle adjustment tool. Background Art
[0002] DPF, also known as diesel particulate filter, is a filter element used to capture and filter particulate matter in diesel vehicle exhaust, which plays a role in purifying exhaust gas and reducing pollutant emissions. It is usually installed in the exhaust system of diesel vehicles, upstream of the exhaust pipe, to capture particulate matter, such as carbon black, dust and other tiny solid particles, to prevent them from being discharged into the atmosphere. DPF is usually composed of fine channels made of ceramic or metal fibers with a high surface area to increase the capture efficiency of particulate matter. When the exhaust gas of a diesel vehicle passes through the DPF, most of the particulate matter is captured in the channel, while relatively clean gas passes through.
[0003] After DPF is produced, it is transported to the OEM for assembly. The OEM needs to install it on the vehicle according to the assembly requirements. In order to meet the use requirements of different vehicles, it is usually necessary to adjust the angle of the DPF's air inlet and exhaust port during assembly. The angle adjustment method used in the prior art is: after manually loosening the clamp, the air inlet and exhaust port at both ends of the DPF are continuously rotated until the required angle that meets the assembly requirements is reached. During this period, a large number of installation tools are required to assist in the adjustment, making the entire assembly process inconvenient, not only inefficient, but also with poor adjustment accuracy due to manual rotation. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] like Figure 3As shown, the utility model provides an embodiment of an engine DPF angle adjustment tooling, which is suitable for DPF. The DPF includes an outer cylinder 6, which is formed by two sections of the cylinder body being spliced and assembled by a V-shaped clamp 61. The ends of the two sections of the cylinder body are respectively provided with an air inlet 62 and an exhaust port 63, and the air inlet 62 and the exhaust port 63 are fixed to the cylinder body by a clamp 64.
[0021] like Figure 1 As shown, the engine DPF angle adjustment tooling includes: a base 1, a first positioning bar 2 and a second positioning bar 3 are fixed on the top of the base 1 with a hexagon socket bolt 4, the first positioning bar 2 and the second positioning bar 3 are used to position the clamp 64, and the spacing between the first positioning bar 2 and the second positioning bar 3 is set according to the installation distance of the DPF, so that the two clamps 64 of the barrel are respectively located above the first positioning bar 2 and the second positioning bar 3.
[0022] Specifically, Figure 1-Figure 3 As shown, a positioning block 5 for positioning the V-shaped clamp 61 is fixed on the side of the first positioning strip 2.
