Description

The utility model relates to the field of mechanical engineering, namely to structural elements of a vehicle body [B62D 25/10, B60R 19/02].

The prior art HYUNDAI RX140 EXCAVATOR [http://galaktikabor.umi.ru/spectehnika/ekskavator_hyundai_rx_140_w, publ. August 7, 2017], containing a hood with niches for lanterns, the vertical projection of which is made in the form of lanterns, and horizontal in the shape of a trapezoid, in which the smaller side forms a rounded shoulder with the surface of the hood.

The disadvantage of the analogue is the high complexity of manufacturing its hood, due to the complex shape of the niches for the lamps.

The closest in technical essence is the NICHO EXCAVATOR HOOD FOR THE LANTERN [ Error! Invalid hyperlink object. publ. 08/11/2017], made in the form of a recess on the hood of an excavator, the vertical projection of which corresponds to the shape of a lantern, and the horizontal projection is made in the form of a trapezoid, in which the small side forms a straight shoulder between the base of the niche and the surface of the hood.

The main technical problem of the prototype is the presence of a shoulder on the outside of the niches for the lamps, which necessitates the use of a hood matrix with special removable parts during its manufacture, which increases the complexity of manufacturing, moreover, after manufacturing the hood when using removable parts on the lamp niche in place A thin edging remains for the joints of the central part and the linings, which must be removed mechanically.

The objective of the utility model is to eliminate the disadvantages of the prototype.

The technical result of the utility model is to reduce the number of parts in the matrix used in the manufacture of the hood with niches for lights, as well as reducing the complexity of its manufacture.

The specified technical result is achieved due to the fact that the niche of the hood of the excavator for the lamp, made in the form of a recess on the hood of the excavator, the vertical projection of which corresponds to the shape of the lamp of the excavator, characterized in that in the horizontal projection the niche is made triangular in shape, while the base of the niche is paired with the surface the hood.

In particular, the base of the niche smoothly mates with the surface of the hood.

In particular, the pairing of the side surfaces of the niche with the surface of the hood is made in a rectangular shape.

A brief description of the drawings.

The figures indicate: 1 - the central element of the hood matrix, 2 - the sidewalls of the hood matrix, 3 - the flange of the sidewalls, 4 - connecting holes, 5 - niches for lights, 6 - the recesses in the sides of the matrix for air intake elements, 7 - the side walls of the matrix for lantern niches, 8 - matrix bases for lantern niches, 9 - flanges of the central element of the hood matrix.

Implementation of a utility model.

A hood with a pair of declared niches for lanterns can be made using a matrix that contains a central element 1 (see Figure 1) and two mirrored sidewalls 2 connected to the central element 1 by bolt connections mounted through connecting holes 4 made in flanges 3 and 9. In the front of the sidewalls 2 of the matrix, niches 5 are made for lanterns, vertical projections of which correspond to the shapes of the used lanterns (not shown in the drawings), in a horizontal projection of niche 5 they are made of a triangular shape (see Fig. 3), while the side The new surfaces 7 of the niches 5 are conjugated with the surface of the sidewalls 2 at right angles, and the bases of the 8 niches 5 are smoothly conjugated with the surface of the sidewalls of 2 hoods. On the surface of the sidewalls 2 there are recesses 6 for air intake elements.

The hood with the declared niches for lanterns is made as follows.

Initially, the matrix for the manufacture of the hood with the declared niches for lanterns is assembled from the central part 1 and two mirror sidewalls 2 for which the sidewalls 2 are positioned and screwed to the central part 1 by bolt connections through holes 4 in the flanges 3 and 9. Thus, after assembly, the inner part of the matrix forms the outer surface of the hood of the excavator.

Then, a separation layer is applied to the inner part of the matrix, then a gelcoat layer of a certain color is applied (a paint layer that forms a smooth colored outer surface of the hood). On a dried gelcoat layer, lay several layers of fiberglass impregnated with resin, molding all the protrusions and depressions of the matrix.

After polymerization of the resin, the matrix is disassembled. The sidewalls 2, combined with a new rear light niche, are diverted to the sides, freeing the side parts of the hood with air intake elements and with niches 5 for the lights. Then the finished hood of the excavator is removed from the central part 1.

To remove from the hood matrix with a known shape of niches for lanterns, it was necessary to make a special removable part for each lantern of the lantern because of collars, so after eliminating collar on niches for lanterns, the finished hood with the declared niches 5 for lanterns can be removed from the matrix without additional parts and reduce the number of detachable parts of the matrix from 5 to 3.

In 2018, the applicant manufactured using this matrix a hood with declared niches 5 for flashlights, the trial operation of which showed that the complexity of manufacturing a hood with niches 5 for flashlights decreased by 25-30% compared with the prototype by reducing the number of detachable parts of the matrix from 5 to 3 and eliminating the need for additional machining of the thin edging, which remained at the junction of the central part 1 and overlays for the shoulders of well-known niches.
