Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of catalyst converter of engine exhaust system, particularly a kind of catalyst converter fixing device.
Background technique
Catalyst converter is mounted in most important purification plant in the vent systems; For reaching better catalyst converter using effect; Generally catalyst converter is located at from the nearest position of motor, can reaches cranking temperature quickly, shorten the cold starting time; Because the engine structure design is very compact, therefore installing and fixing of catalyst converter has been proposed new requirement.
At present, general automobile all adopts a support to be fixed on the cylinder body with catalyst converter, and current catalyst converter fixed structure is as shown in Figure 3; Support 7 one ends are welded on the catalyst converter 1; The other end is the face of installing mutually with cylinder body, on this face, is provided with left construction bolt hole 8 and right construction bolt hole 9, through bolt support 7 is fixed on the cylinder body respectively; Position owing to catalyst converter 1 in installation process concerns; Catalyst converter 1 has blocked a jiao of left construction bolt hole 8, and bolt can not use instrument installations such as sleeve when causing installing, because assembly accumulation tolerance or preparation process tolerance; Support and cylinder body are installed and are occurred spiro keyhole position often and do not align or deviation is arranged, and the validity of assembling can not guarantee.
Summary of the invention
The purpose of the utility model is to have the problems referred to above to existing technology, has proposed a kind of catalyst converter fixing device, and this fixing device can solve existing catalyst converter assembly process medium-height trestle can not be installed to the problem on the cylinder body smoothly.
The purpose of the utility model can realize through following technical proposal: a kind of catalyst converter fixing device; This fixing device is arranged between catalyst converter housing and the engine cylinder-body; It is characterized in that this fixing device comprises upper bracket and lower support frame, described upper bracket is fixed on the catalyst converter housing; Described lower support frame is through being bolted on the engine cylinder-body, and described upper bracket is fixedly connected through demountable structure with lower support frame.
In the practical set process; Preferentially lower support frame is installed on the cylinder body; Again upper bracket is fixedly connected on the lower support frame through demountable structure; Therefore avoided support bolt in being installed to the cylinder body process can't use instrument installations such as sleeve, promptly solved the assembly process medium-height trestle and can not be installed to the problem on the cylinder body smoothly.
In above-mentioned catalyst converter fixing device, described upper bracket is connected through bolt with lower support frame.This bolt can use instrument installations such as sleeve.
In above-mentioned catalyst converter fixing device, link to each other with the upper bracket bolt hole at end place of described lower support frame is strip.
In above-mentioned catalyst converter fixing device, the bolt number that described upper bracket is fixedly connected with lower support frame is 2～4.
In above-mentioned catalyst converter fixing device, link to each other with the cylinder body bolt hole at end place of described lower support frame is strip or circle.
In above-mentioned catalyst converter fixing device, link to each other with the cylinder body number of bolt hole at end place of described lower support frame is 1～3.
In above-mentioned catalyst converter fixing device, described lower support frame link to each other with upper bracket vertical line and the lower support frame of bolt hole at end place link to each other with cylinder body the bolt hole that the end locates vertical line at angle.Two big holes of lower support frame can be so that lower support frame be relatively horizontal and vertically move with engine cylinder-body, and the strip hole of lower support frame makes being installed in of lower support frame and upper bracket that enough installation surpluses arranged on the fore-and-aft direction.This structure can make lower support frame with respect to upper bracket or engine cylinder-body laterally and vertically move, and then can eliminate the tolerance that making and assembling etc. are with.
In above-mentioned catalyst converter fixing device, described lower support frame is for what bend, and the angle that is bent to form is 90 °～120 °.Lower support frame one bending side is fixedly connected through demountable structure with upper bracket, and another bending side is through being bolted on the cylinder body, and the space that this structure produces makes instrument such as sleeve be enclosed within on the bolt at an easy rate and has revolution space.The too small meeting of angle of lower support frame bending causes bending side to shelter from bolt hole, and the excessive upper bracket that causes can't be installed on the lower support frame smoothly.
Compared with prior art, this catalyst converter fixing device has the following advantages:
All bolts all can use instrument installations such as sleeve when catalyst converter is installed; In conjunction with the as installed situation, have flexibility in this fixing device assembly process, the assembling of avoiding insufficient space to cause has some setbacks; Wherein the bolt hole design is strip; Can regulate through moving upper bracket and lower support frame, in the process of installing, will play the tolerance compensating effect, improve the degree of accuracy of assembling.
