Description

Technical Field

[0001] The invention relates to the technical field of automobile exhaust pipe processing auxiliary devices, and in particular to a cutting positioning structure and a positioning method for automobile exhaust pipes. Background Art

[0002] The automobile exhaust pipe is a key component in the automobile exhaust system. It is a tubular channel system used to collect and guide the exhaust gas generated by the engine combustion to the outside of the vehicle. It is usually composed of multiple parts, including exhaust manifold, exhaust bellows, three-way catalytic converter, muffler, tail throat, etc. It undertakes important functions such as exhaust gas emission, noise reduction, exhaust gas purification, pressure balance, and to a certain extent, improving vehicle performance. It plays a vital role in the normal operation of the car and environmental protection. The automobile exhaust pipe needs to be cut during the production and processing process. The cutting and positioning structure for automobile exhaust pipes is a device or mechanism used to accurately position the exhaust pipe during the production and processing of automobile exhaust pipes for easy cutting operations; To this end, the patent with the authorization announcement number CN112276204B discloses a continuous cutting device for automobile exhaust pipes, including a frame, a cutting device, a fixing device, an exhaust pipe body and a conveying device. The frame includes a track plate and a seat plate symmetrically fixed on the left and right sides of the track plate. The cutting device includes a slide seat, a blade box, a cutting blade and a cutting motor. The fixing device includes a fixing sleeve and a fixed pressure plate. The conveying device includes a connecting rod, an axle seat and a conveying roller. The device fixes the exhaust pipe body through the fixing device, and the fixing and disassembly are convenient. When cutting, the cutting position can be cooled to avoid overheating of the exhaust pipe body and the cutting blade. The pipe after cutting and the pipe to be cut are conveyed by the conveying device, so that the processing procedure is simplified and the processing efficiency is improved. The above-mentioned prior art solution has the following defects: the exhaust pipe body is inserted into two symmetrical fixed sleeves, and the air cooler blows air to push the slide plate and makes the fixed pressure plate fix the exhaust pipe body. Although this method can clamp the exhaust pipe more conveniently, the stability of the exhaust pipe positioning is poor, resulting in the exhaust pipe being easily offset during the cutting operation, thereby affecting the processing accuracy.
