Embodiment 1

[0019] Such as figure 1 As shown, a clamping method of a pre-welding purifier of the present invention is realized through the following steps: the clamping process is: first, the semi-finished steel plate that has completed the reel process is manually placed on the clamp, and the arc on the mast 2 shaped bayonet 6 for positioning, and finally under the fixing action of the pressing mechanism, manual welding is started to complete the manufacture of the finished purifier shell, wherein the fixture includes a base 1, a mast 2, a support mechanism, an arc bayonet 6, Press-down mechanism, the base 1 is vertically connected with the mast 2, the support mechanism is arranged on the base 1, the arc bayonet 6 is arranged in the middle of the mast 2, the top of the mast 2 is provided with a press-down mechanism, the support mechanism, the arc The axis lines of the shaped bayonet socket 6 and the pressing mechanism coincide. The semi-finished steel plate that has completed the rollin...

Embodiment 2

[0021] Such as figure 1 As shown, this embodiment is based on Embodiment 1, and the support mechanism includes a support column 4 and a plurality of support plates 3 , and the plurality of support plates 3 are distributed around the support column 4 in a circular array. The function of the support column 4 set in the middle of the support plate 3 is to guide the semi-finished steel plate of the necking to be accurately placed on the welding position, and the surrounding support plate 3 fixes the steel plate itself, so as to avoid the displacement of the semi-finished steel plate when the necking is welded. welding effect.

Embodiment 3

[0023] Such as figure 1 As shown, this embodiment is based on the embodiment 2, and the top of the support plate 3 is also provided with a protrusion 5 . The protrusion 5 at the bottom of the support plate 3 acts as a limiter. During welding, it is inevitable that it will collide with the semi-finished steel plate of the neck. The protrusion 5 can well limit the semi-finished steel plate of the neck between the support plate 3 and the support plate. between the columns 4 to prevent their displacement.

Abstract

The invention discloses a clamping method of a pre-welding purifier. The clamping method comprises a clamping working procedure, wherein the clamping working procedure comprises the steps that firstly, a semi-finished steel plate product subjected to a reeling working procedure is manually arranged on a clamp, is positioned through arc-shaped bayonets formed in a mast and finally is manually welded under the fixing effect of a pressing-down mechanism to complete manufacturing of a finished purifier housing product. The clamp comprises a base, the mast, a supporting mechanism, the arc-shaped bayonets and the pressing-down mechanism, wherein the base is vertically connected with the mast, the supporting mechanism is arranged on the base, the arc-shaped bayonets are formed in the middle of the mast, the pressing-down mechanism is arranged at the top of the mast, and the axes of the supporting mechanism, the arc-shaped bayonets and the pressing-down mechanism coincide. Welding can be quickly and effectively performed only by arranging the reeled semi-finished product in the supporting mechanism.

Description

technical field [0001] The invention relates to the field of exhaust gas purification of engines and automobiles, in particular to a clamping method for a pre-welding purifier. 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, HC and NOx emitted from automobile exhaust into harmless carbon dioxide, water and nitrogen. Because this catalytic converter can convert the main harmful substances in the exhaust gas into harmless substances at the same time. With the increasingly stringent environmental protection requirements, more and more cars are equipped with exhaust gas catalytic converters and oxygen sensor devices. It is installed in the engine exhaust pipe, through the redox reaction, carbon dioxide and nitrogen, so it is also called three-way catalytic converter. [0003] The production of three-way catalytic converters ge...
