Abstract

A mounting structure of a radiator, comprising a core (3) having tubes (2) and fins, a header plate (4) installed at the ends of the tubes (2), and a tank (5) fitted to the header plate (4), characterized by comprising a side plate (11) fitted to both ends of the tank (5) and fitted to a core (3) side member and a general set nut (12) installable on the side plate (11). Since the mounting structure can mount the radiator thereon by fitting the general set nut (12) to the side plate (11) without using a machined part or a forged part, the assembly and manufacturing operations of the structure can be simplified and its production cost can be reduced.

Description

Specification

Mounting structure of the radiator

Technical field

The present invention relates to a mounting structure of a radiator used in automobiles, construction machines and the like.

Background art

[0002] In general, automobiles, construction machines and the like are provided with a radiator in order to control heat generated by engine power in an optimal state. As shown in FIG. 8, a conventional radiator 1 comprises a core 3 consisting of a tube 2 and fins (not shown), a header plate 4 provided at the end of the tube 2 and a header plate It is roughly composed of a tank 5 fitted to 4. A boss 7 screwed with a female screw 6 is supported at both ends of the tank 5, and the boss 7 is integrally brazed to the tank 5, and a bolt (not shown) or the like is screwed to the boss 7. By doing this, the radiator 1 is fixed at a predetermined place. Further, side plates 9 are provided at both ends of the tank 5 so as to close the open end 8, and the side plates 9 are coupled to core supports (not shown) provided on both sides of the core 3. Thus, the tank 5 is fixed to the core 3 side. (The known prior art documents related to the present invention are not known by the applicant because they were invented based on known and publicly used prior art).

Disclosure of the invention

Problem that invention tries to solve

However, in the above-described conventional radiator attachment structure, the female screw 6 is screwed into the boss 7 and the boss 7 is carried to the tank 5 by cutting or forging. It took a lot of time to manufacture. Therefore, there was a problem that it was difficult to reduce manufacturing costs.

The present invention has been made to solve the above-mentioned problems, and provides a mounting structure of a radiator which can reduce the manufacturing cost.

Means to solve the problem

[0005] The present invention provides a core comprising a tube and a fin, and a core provided at the end of the tube A mounting structure of a ladder having a header plate and a tank fitted to the header plate, the side plate being attached to both ends of the tank and being attached to the member on the core side, the side plate And a universal set nut attachable to the plate.

Further, according to the present invention, the general purpose set nut can be attached to the side plate that eliminates the need to use a cut part or a forged part, so that the radiator can be attached. It is possible to simplify and reduce the manufacturing cost.

Effect of the invention

As described above, according to the present invention, since the universal set nut can be attached to the side plate that eliminates the need to use a cut part or a forged part, the radiator can be attached. Various excellent effects such as simplification of the manufacturing operation and reduction of the manufacturing cost can be obtained.

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 17 shows the attachment structure of the radiator according to the embodiment of the present invention. About the same composition as the above-mentioned conventional example, in order to simplify explanation, in Drawing 1 and Drawing 7, the same numerals as Drawing 8 are attached, and detailed explanation about those composition is omitted.

In the present embodiment, as shown in FIG. 1, the mounting structure of the radiator is constituted by the side plate 11 and the universal set nut 12.

As well shown in FIG. 2 to FIG. 5, the side plate 11 has a core side plate portion 13 formed so as to be able to close the open end 8 (see FIG. 1) of the tank 5, and a core side plate It comprises a set nut mounting plate portion 14 bent at a right angle from the portion 13 and a tank side plate portion 15 bent at a right angle from the set nut mounting plate portion 14. As shown in FIG. 3, a required number of, for example, two locking holes 16 are drilled in the end portion of the core side plate portion 13, and the required portion of the central portion is, for example, two places. A hooking portion 17 is formed. Further, as shown in FIG. 4, a required number of, for example, two round holes 18 are drilled in the set nut mounting plate portion 14, and notches 19 are formed on both sides thereof. . Furthermore, as shown in FIG. 5, a required number of claws 20 is provided at the end of the tank side plate 15, for example, Two hooks are formed, and hooks 21 are formed on the respective claws 20.

As well shown in FIG. 6, the general-purpose set nut 12 is formed in a flat U-shape, and has a clamp portion 22 having panel properties and a nut portion 23 provided so as to protrude from the clamp portion 22. And a female screw 24 is screwed into the nut portion 23. Further, a circular hole 25 is formed at a position corresponding to the female screw 24 of the clamp portion 22, and a hook-shaped stopper 26 is formed around the circular hole 25. Furthermore, the end of the clamp portion 2 is bent outward to form a guiding portion 27.

In order to assemble such a mounting structure of the ladder, the general-purpose set nut 12 is inserted into the side plate 11 from each of the notches 19 of the set nut mounting plate portion 14, and set by the clamp portion 22. Hold nut mounting plate section 14. Then, the stopper portion 26 is engaged with the round hole 18 of the set nut mounting plate portion 14, and the universal set nut 12 is securely fixed to the side plate 11. At this time, since the stopper portion 26 has a wedge shape and the guiding portion 27 is formed on the clamp portion 22, the mounting work of the universal set nut 12 to the side plate 11 can be smoothly performed.

Next, with the two general purpose set nuts 12 attached to the set nut mounting plate 15 as described above, the respective hooking parts 17 and 21 are hooked to the tank 5, and the core 3 The core supports (not shown) provided on both sides of the frame are locked in the locking holes 16 of the core side plate portion 13. As a result, the side plate 11 is securely fixed to the tank 5, the universal set nut 12 is disposed at a predetermined position along the tank 5, and the tank 5 is securely fixed to the core support via the side plate 11. Ru.

The shape of the side plate 11 is not limited to the above-mentioned shape. For example, as shown in FIG. 7, the side plate 11 has a flat shape so that the general-purpose set nut 12 is arranged vertically to the tank 5. You may

[0015] Also, the side plate 11 may be provided to be locked to the header plate 4 on the core side.
