Problems solved by technology

If the GBD is too small, the liner does not have the necessary wrapping capacity for the carrier; if the GBD is too large, the fibers of the liner may rupture and affect the wrapping capacity of the carrier; in addition, if the GBD is too large, the carrier may be damaged due to excessive pressure. and burst

Embodiment 1 3

[0023] Embodiment 1 The working mode of the triangulation laser measurement system

[0024] Such as figure 1 As shown, the triangulation laser measurement system includes a laser emitter, a lens, and a CCD; the light emitted by the laser source is collimated by a condenser lens and then projected onto the surface of the measured object, and the diffusely emitted light forms a spot image on the CCD through a receiving lens . The displacement of the surface of the measured object causes the displacement of the light spot on the CCD. When the surface of the object changes relative to the reference plane, the light spot formed by the diffuse reflection light collected by the receiving lens on the photosensitive surface of the photoelectric detection element also changes accordingly, and the photosensitive surface is obtained from the processing control circuit of the photoelectric detection element. The information of the displacement change of the light spot, so that the change...

Embodiment 2 3

[0026] The production method of embodiment 2 three-way catalytic converter

[0027] The specific process includes:

[0028] (1) Start the computer and activate the measurement window.

[0029] (2) Input the product information of the gasket, the thickness of the metal shell and other parameters.

[0030] (3) Take out the carrier and liner, and put the carrier on the turntable.

[0031] (4) Click the measurement button on the screen, the turntable starts to rotate, the laser scans the carrier, starts to measure the carrier profile, and displays it on the screen:

[0032] (5) Turn on the electronic scale switch, set to zero first, then put in the liner, press the weighing button, and start measuring the weight of the liner to calculate the surface density of the liner;

[0033] (6) Click the print barcode button to automatically print a barcode label, tear off the label and stick it to the center of one end of the carrier. The barcode information must include product category...

Abstract

The invention discloses a production method of a three-way catalyst. The production method includes: calculating theoretical clearance of the three-way catalyst by detecting a section profile, thickness of a shell and packing weight of a catalyst carrier; after completing sizing process, detecting whether packing of the catalyst conforms to GBD (gap bulk density) demands or not. By the production method, quality and precision of three-way catalyst products can be effectively improved, yield rate of the products can be increased, and industrial production is facilitated.

Description

technical field [0001] The invention belongs to the field of auto parts production, and in particular relates to a three-way catalytic converter production method for improving product quality and precision. Background technique [0002] The three-way catalytic converter is the most important external purification device installed in the automobile exhaust system. It can convert harmful gases such as CO, carbon monoxide, HC hydrocarbons and NOx nitrogen oxides from automobile exhaust into Harmless carbon dioxide, water and nitrogen. Because this catalytic converter can simultaneously convert the three main harmful substances in the exhaust gas into harmless substances, it is called three-way. [0003] Generally, a three-way catalytic converter includes a ceramic carrier (the core of the three-way catalytic converter), a steel casing, and a gasket between the carrier and the casing. [0004] Due to the mutual extrusion of the ceramic carrier, steel shell and liner, the area...
