Description

Positioning tool for mounting commercial vehicle aftertreatment assembly

Technical Field

The utility model relates to the technical field of post-treatment assembly installation, in particular to a positioning tool for mounting a post-treatment assembly of a commercial vehicle.

Background

The current commercial vehicle has more and more compact system arrangement, and particularly after six stages of emission implementation, the design of an exhaust pipe tends to be short, and the displacement capability and decoupling capability of a shorter corrugated pipe are limited. If a large error occurs in the positioning of the post-treatment assembly, the installation state of the corrugated pipe in the exhaust pipe is seriously affected, and the service life of the corrugated pipe is short. On the other hand, the weight of the post-treatment assembly in the six-stage state is increased, the structure and the installation of the post-treatment assembly are more complex, and in order to adapt to the operation of an assembly line, the post-treatment assembly needs to adopt an off-line split charging mode and an on-line assembly mode. In the mode, the problem of poor installation state of the exhaust pipe of the subsequent station is solved, and the space position of the post-treatment assembly is adjusted, so that time and labor are wasted.

The prior patent is a U-shaped post-processor inclined mounting bracket (CN 212690167U), which is a mounting structure of a post-processing assembly, and cannot finish the high-precision mounting of the post-processing assembly without a positioning device.

The prior patent discloses an assembly fixture (CN 203738369U) for an exhaust aftertreatment device, which is an assembly fixture for an aftertreatment assembly, has the main effects of improving the assembly efficiency, and has two defects, namely, although a positioning device is arranged, the positioning of the assembly fixture is mainly used for ensuring the assembly consistency of the aftertreatment assembly relative to a frame: 1. with the frame as the benchmark location, only in order to keep the assembly uniformity of aftertreatment and frame, along with the shortening of blast pipe especially bellows, in order to satisfy the high accuracy of aftertreatment assembly and blast pipe and be connected, guarantee the good state of bellows when the assembly, the installing support all designs has the slotted hole that is used for adjusting aftertreatment assembly installation space position, uses the frame as the benchmark location can not guarantee the installation accuracy. 2. Because the post-treatment assembly in the second technical scheme has a simple structure, the post-treatment cylindrical barrel is used as an object, radial positioning is not needed, and the self structure and the installation of the post-treatment assembly in the sixth stage are more complex.
