Description

Engine tail gas protection cover is with examining utensil

Technical Field

The utility model belongs to the technical field of soft shell product detection, and particularly relates to a detection tool for an engine tail gas protection cover.

Background

With the development of industrial application, products and parts with inner cavities are more and more refined. The exhaust gas heat insulation cover of the automobile engine is generally formed by welding and assembling two irregularly-shaped semicircular metal shells, as shown in fig. 1.

When a group of heat preservation covers are butt-jointed and mounted on the cylinder body, if half of butt joint parts are too long, the heat preservation covers can mutually collide to influence the assembly effect, so that the gap between the heat preservation covers and the cylinder body is too large, the state of dead package appears, and the follow-up three-way catalytic reaction effect of the customer product is influenced. If the butt joint is too short, the overlapping area of the products on both sides is reduced, so that the welding spots cannot cover and fix the products on both sides.

Thus, there is a need for accurate limits on the length of the heat shield interface to be welded, and therefore, measurements are required before assembly. The heat-insulating cover is made of stainless steel with the thickness of 0.15mm, so that the heat-insulating cover body is soft and easy to deform (within the elastic deformation range), and the shape is irregular, so that a reference surface is difficult to find, the actual length of the butt joint part cannot be accurately and rapidly measured by the conventional measuring means, and whether the requirement is met or not cannot be accurately judged.

Disclosure of utility model

In order to solve the defects in the prior art, the utility model provides the gauge for the engine tail gas protection cover, which can quickly and effectively measure the width of the butt joint surface of the protection cover accurately, and greatly improves the detection efficiency.

The aim of the utility model is achieved by the following technical scheme:

The utility model provides an engine tail gas safety cover is with examining utensil, including detecting the mould main part, detect the size and the shape of mould main part and standard safety cover size and shape the same, detect the both ends of mould main part and extend to the outside and be provided with the end of bending.

Preferably, the detection die main body corresponds to the half body of the protective cover in size and shape.

Preferably, a measuring scale mark is arranged at the connecting part of the detection die main body and the bending end.

Preferably, the measuring scale mark is arranged at one end of the detection die main body.

The beneficial effects of the utility model are as follows: the beneficial effects of the utility model are as follows: the size of the connecting part of the tail gas protection cover to be detected can be accurately measured, so that whether a product meets welding requirements or not can be rapidly judged, and the practicability is high.

Detailed Description

The utility model discloses a gauge for an engine tail gas protection cover, which is shown in combination with fig. 2-7, and comprises a detection die main body 1, wherein the size and the shape of the detection die main body 1 are the same as those of a standard protection cover, and bending ends 2 are arranged at the two ends of the detection die main body 1 in an outward extending mode. The connecting part of the detection die main body 1 and the bending end 2 is provided with a measuring scale mark 3. In this embodiment, the measurement scale mark 3 is disposed at one end of the detection module body 1, and the bent end at the other end is used as an initial positioning end when detecting a product. The standard protective cover refers to a protective cover with qualified standard size and shape. Further, the size and shape of the detection mold main body 1 corresponds to those of the half protection cover, and the product to be detected is usually half protection cover, so the detection mold main body 1 is half protection cover main body structure. The units of the measuring graduation marks 3 are millimeters.

For a better understanding of the present utility model, reference is made to the following description taken in conjunction with the accompanying drawings.

When the connection portion D between the first protective cover 41 and the second protective cover 42 is required to be detected, whether the connection portion D meets the requirement is detected. During measurement, the product 4 is attached to the surface of the detection die body 1, wherein one end 43 of the product 4 is flush with the surface of one bending end, and the other end 44 of the product is specifically compared with the measurement scale mark 3 on the detection tool to check whether the product meets the size requirement.

The inspection tool is simple and reliable in actual operation, and can complete self-inspection by operators in production, and the risk of bad production can be minimized to the greatest extent by matching with QA personnel inspection. The practicability is strong. The utility model is based on the detection principle that the standard component is used as a reference, and the product in a non-theoretical state is measured by using the detection tool with a standard contour, so that the purpose of accurately measuring the size of the product is achieved. The utility model can be used for detecting the tail gas protection cover of the engine and can be applied to other soft shell products.

Finally, it should be noted that: the terms "upper," "lower," "left," "right," "vertical," "horizontal," "inner," "outer," and the like refer to an orientation or positional relationship based on that shown in the drawings, merely to facilitate description of the utility model and simplify the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
