Abstract
A dismounting tool for an oxygen sensor of a three-way catalytic converter includes sleeves. The tool is characterized in that the two sleeves are welded, wherein an opening is formed at a side edge of one of the sleeves, so as to enable an oxygen sensor wire harness to pass therethrough. The utility model can directly dismount the oxygen sensor with less time and labor; and the tool simplifies the dismounting procedures, and is easy to operate.
Description
Technical field
The utility model belongs to the technical field of lambda sensor dismounting, particularly a kind of ternary catalyzing unit lambda sensor dismantling device.
Background technology
The motor vehicle emission performance is one of very important performance of automobile, according to China's discharge standard, automobile will be done emission testing repeatedly in the endurancing process, yet in the research and development of products process of engine, need monitor constantly emissions data, automatically controlled demarcation personnel often fetch data from the lambda sensor of ternary catalyzing unit, so just need dismounting lambda sensor repeatedly, in real work, each dismounting sensing all needs dismounting chassis backplate, the exhaust insulation cover, blast pipe and ternary catalyzing unit connector, exhaust manifold, and then from blast pipe, dismantle lambda sensor with spanner, and so just cause the distortion of blast pipe pad easily, damage, the blast pipe pad is disposable often, simultaneously cause the gas leakage of exhaust pipe connection section position easily, promptly require great effort, lose time again with traditional instrument dismounting, simultaneously also can cause economic loss, and influence the test progress.
Summary of the invention
The utility model purpose provides a kind of ternary catalyzing unit lambda sensor dismantling device.
The technical solution of the utility model is achieved in that
Ternary catalyzing unit lambda sensor dismantling device, it comprises sleeve, it is characterized by: two sleeves weld together, and open a gap on one of them sleeve side, and the lambda sensor wire harness passes from the centre.
The utility model directly dismounting lambda sensor promptly saves time and is laborsaving; Mounting-dismounting programme is oversimplified, and operation easily.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the main TV structure schematic diagram of the utility model tube 2;
Fig. 3 is the plan structure schematic diagram of the utility model sleeve 2.
Specific embodiments
Describe specific embodiments of the present utility model in detail below in conjunction with accompanying drawing.
Ternary catalyzing unit lambda sensor dismantling device, it comprises sleeve 1, it is characterized by: two sleeves weld together, and open a gap 3 on one of them sleeve 2 side, and the lambda sensor wire harness passes from the centre.
The utility model is on the basis of traditional sleeve barrel tool, and two conventional sleeve 1 are welded together, and opens a gap 3 on one of them sleeve 2 side, so that the lambda sensor wire harness passes from the centre, just more saves time in dismantlement work like this, laborsaving.
Above the utility model specific embodiment is described in detail in conjunction with the accompanying drawings, but the utility model is not limited to the foregoing description, as long as in the utility model real work afterwards, can be combined into the new tool of various needs of work with reference to this mode.
