Multi-use inspection tool for composite exhaust pipe assembly

Abstract

The invention relates to detecting tools for exhaust pipes and discloses a detecting tool for diversified utilization of a combined type exhaust pipe assembly. The detecting tool comprises a fixing unit, a first detecting tool unit and a second detecting tool unit. The first detecting tool unit comprises a first base, a first supporting table, a detecting device and a pipe abutting table. The detecting device comprises a movable block and a fixed block, scale lines are formed in the fixed block, a pointer is arranged on the movable block, a line-shaped hole and a locating rod are arranged in the movable block, one side of the movable block is in slide connection with a side portion of the fixed block, and the other side of the movable block is in clamp connection with the fixed block. The second detecting tool unit comprises a second base, a second supporting table and a plurality of movable limiting blocks, and the two sides of the upper portion of the second supporting table are connected with a datum plane or a detection surface. The detecting tool is simple in structure and convenient to use; welding and debugging of the exhaust pipe assembly and detecting of the installation accuracy of the exhaust pipe assembly can be achieved through the detecting tool. Meanwhile, the detecting tool is also capable of carrying out vertical deviation detection on an exhaust pipe bracket installed on an exhaust pipe.

Description

technical field [0001] The invention belongs to the field of auto parts, and relates to a checker for an exhaust pipe, in particular to a checker for multiple utilization of a compound exhaust pipe assembly. Background technique [0002] Since the exhaust pipe assembly is assembled through multiple exhaust pipes with different angles and the exhaust pipe bracket installed on the exhaust pipe, welding the exhaust pipe assembly is different from welding other sheet metal parts. , the main differences are as follows: 1. The welding process must be arc welding process; The geometry of the gas pipe cannot be adjusted like welding other sheet metal parts. [0003] In the prior art, the staff adjusts the geometric dimensions of the exhaust pipe through long-term accumulated experience to complete the welding and debugging work of the exhaust pipe, so the exhaust pipe welded by the above-mentioned prior art not only has a The problem of high experience requirements, but also the p...

[0002] Since the exhaust pipe assembly is assembled through multiple exhaust pipes with different angles and the exhaust pipe bracket installed on the exhaust pipe, welding the exhaust pipe assembly is different from welding other sheet metal parts. , the main differences are as follows: 1. The welding process must be arc welding process; The geometry of the gas pipe cannot be adjusted like welding other sheet metal parts

[0003] In the prior art, the staff adjusts the geometric dimensions of the exhaust pipe through long-term accumulated experience to complete the welding and debugging work of the exhaust pipe, so the exhaust pipe welded by the above-mentioned prior art not only has a The problem of high experience requirements, but also the problem of low structural stability of the exhaust pipe and low qualified rate of finished products, which will increase the production cost of the exhaust pipe and the workload of the early stage debugging of the exhaust pipe

[0004] In the prior art, the exhaust pipe bracket of the automobile is tested by using inspection tools at the production site. The existing inspection tools for detecting the exhaust pipe bracket can only judge whether the exhaust pipe bracket is qualified (OK) or not. Qualified (NG), the actual installation deviation value of the exhaust pipe bracket cannot be measured, and the value needs to be measured by a three-coordinate measuring machine or other measuring devices, which not only increases the measurement cost, but also wastes time, so it is necessary to improve
