Referring to fig. 1 and 2, an embodiment of the present application provides a method for installing a rapid sample on an automobile sludge model, which includes the following steps:

The embodiment of the application mainly uses the disc shape, and the specification (diameter and thickness) mainly has: 10mm by 3mm, 16mm by 3mm, 20mm by 5mm, 25mm by 7mm, etc.

S2: determining a suction force value required by the rapid sample 1 according to the weight of the rapid sample 1;

S3: determining the size and the number of target magnet groups required by the rapid sample 1 according to the suction force value and the horizontal tension value of each magnet group to be selected, and selecting the corresponding magnet group pairs with the size and the number from the magnet groups to be selected as the target magnet groups 2;

The size and the number of the target magnet groups required by the rapid sample 1 can be determined according to the horizontal tension and the suction force values of the magnets with different specifications in the table 1, and then the magnet groups meeting the conditions are screened from the plurality of candidate magnet groups provided in the step S1 to be used as the target magnet groups 2 for later use.

The following is illustrated by two examples.

Example 1, a certain medium-sized vehicle 1: 1, installing a quick sample piece of a front cover grid of an oil sludge model:

weighing by using an electronic scale, wherein the weight of the front cover grating rapid sample piece is 2200 g, and estimating 4 target magnet groups with the diameter of 16mm and the thickness of 3mm by referring to a horizontal tension value of a table I according to the weight of the 2200 g of the front cover grating rapid sample piece.

Before one magnet 20 of the target magnet group 2 is fixed to the rapid sample 1 in step S4, the method further includes the steps of:

s30: pre-assembling a rapid sample piece 1 on an oil sludge model 3 through a limiting structure 4;

In step S4, fixing one magnet 20 in the target magnet group 2 to the rapid sample 1, and determining the corresponding position of the magnet 20 on the sludge model 3; the method specifically comprises the following steps:

s40: fixing one magnet 20 in the target magnet group 2 on the rapid sample 1;

the position suitable for fixing the magnet 20 is selected according to the shape of the back of the rapid sample piece 1, marking is carried out, and then the magnet 20 is fixed at the marked position through the super glue.

S41: the rapid sample piece 1 is preassembled on the clay model 3 again, and no gap exists between the rapid sample piece 1 and the limiting structure 4;

when there is no gap between the quick sample 1 and the limit structure 4, it indicates that the surface difference between the quick sample 1 and the clay model 3 reaches the preset surface difference, and at this time, the quick sample 1 reaches the pre-assembly state in step S31.

S42: and determining the corresponding position of the magnet on the rapid sample piece 1 on the clay model 3, and marking the corresponding position.

The corresponding position of the magnet 20 on the sludge model 3 is determined based on the projected position of the magnet 20 fixed to the rapid sample 1 on the sludge model 3 when the rapid sample 1 is attached to the sludge model 3.

In step S6, the rapid sample 1 is assembled on the clay model 3, and the magnet 20 far from the rapid sample 1 is fixed on the corresponding position of the clay model 3, which specifically includes the following steps:

s60: digging a mounting hole 5 at a corresponding position, wherein the diameter of the mounting hole 5 is larger than that of the magnet 20;

the depth of the installation hole 5 is 30mm, the installation hole 5 is filled with the adhesive 6, the magnet 20 can be completely wrapped by the section of the adhesive 6, and the diameter of the installation hole 5 is larger than that of the magnet 20.

S61: filling the mounting hole 5 with an adhesive 6, wherein the height of the adhesive 6 is higher than that of the limiting structure 4;

the adhesive 6 of the embodiment of the present application is a paste-like material, which is plastic and can deform when pressed, and the height of the adhesive 6 needs to be higher than that of the limiting structure 4 in order to fix the magnet 20 on the adhesive 6 by pressing.

s63: and (3) pressing the rapid sample piece 1 until no gap exists between the rapid sample piece 1 and the limiting structure 4, and fixing the magnet 20 far away from the rapid sample piece 1 on the clay model 3 through the adhesive 6.

When there is no gap between the quick sample 1 and the limit structure 4, it indicates that the surface difference between the quick sample 1 and the clay model 3 reaches the preset surface difference, and at this time, the quick sample 1 reaches the pre-assembly state in step S31. Meanwhile, the embodiment of the application utilizes the characteristic that a paste mixture formed by uniformly mixing the paste A, B component instead of wood has plasticity in a certain time before curing, and has the characteristics of good dimensional stability and mechanical strength after curing, so that the effect of accurately fixing the magnet 20 and the rapid sample 1 is achieved.

Preferably, the adhesive 6 is 5mm to 10mm higher than the confinement structure 4.

The adhesive 6 is compressed and deformed after being pressed.

Step S63 is to press the rapid sample 1 until there is no gap between the rapid sample 1 and the position-limiting structure 4, and the method further includes the following steps:

s64: and adjusting the rapid sample piece 1 so that the gap between the rapid sample piece 1 and the clay model 3 reaches a preset gap.

And finally, adjusting the clearance and the surface difference between the rapid sample 1 and the clay model 3 to reach the design values to complete the installation of the rapid sample 1.

Further, a spacer 7 is provided between the two magnets 20 in the target magnet group 2, and the area of the spacer 7 is larger than the cross-sectional area of the adhesive 6.

Since the adhesive 6 has an increased cross-sectional area after being pressed, it is necessary to prevent the adhesive 6 from adhering to the rapid sample 1 and the magnets 20 on the rapid sample 1, and to prevent the separation film 7 between the two magnets 20 to separate the adhesive 6.

Preferably, the separation film 7 is made of one of polyvinyl chloride, polyethylene, polypropylene and polystyrene.

The isolating film 7 is made of polyvinyl chloride, polyethylene, polypropylene, polystyrene and other resins, and is not mutually bonded with the adhesive 6, namely the paste mixture, so that the effect of isolating the rapid sample piece 1 from the paste mixture is achieved, and the problem that the paste mixture sticks to the rapid sample piece 1 in the curing process, so that the rapid sample piece cannot be detached is solved.
