Description

Bushing Mounting Structure {A MOUNTING STRUCTURE OF BUSH CONNECTING}

TECHNICAL FIELD The present invention relates to mounting structures, and more particularly, to bush engagement mounting structures used for fluidly connecting / fastening parts.

In general, when fixing and engaging a part in a predetermined position, in order to make the fixed part flowable, a mounting bracket 50 as shown in Figs. 4 and 5 is used.

That is, the mounting bracket 50 is fixed to the body (side member or cross member, etc.) and the coupling arm 51 is formed on the opposing portion, and the coupling bracket 51 is formed opposite to the coupling arm 51 and has a different diameter. The first and second coupling holes 52 and 53 and the coupling arm 51 of the mounting bracket 50 are fitted with a predetermined tolerance and penetrate to correspond to the first and second coupling holes 52 and 53. Thread 55 formed in the inner surface of the second coupling hole 53 through the component 55, such as a pump formed with the hole 54, the first and second coupling holes 52 and 53 and the through hole 54 described above. It consists of a fixing bolt 56 which is screwed together (not shown).

Since the mating surfaces of the mounting bracket 50 and the component 55 are both surfaces obtained through machining, there are machining and design tolerances, so that the mounting bracket 50 and the component 55 are about 0.3 between the mounting bracket 50 and the component 55. There is a tolerance of ˜0.7 mm.

Here, a relatively large load is applied to a portion to which the mounting bracket 50 and the component (part which operates like a pump) 55 are connected, so that the stiffness is lowered due to the above tolerance. 57).

That is, in the state of being inserted into the first coupling hole 52 having a large diameter, the component 55 and the mounting bracket 50 are disposed between the bolt 56 and the component 55 by the bolt 56. By tightening, the bush 57 urges the component 55, thereby eliminating the tolerance of the mounting bracket 50 and the component 55 described above.

However, if the components are placed between the engaging arms of the mounting bracket as described above and the components are pressed against the bush so that no tolerance occurs, the bolt must inevitably push the bush toward the component side. There is a problem that the bush must be mounted on the head of the head, which causes a lot of restrictions in the installation of the mounting bracket.

That is, since the relative position of the mounting bracket and the component must always be pushed toward the bolt head opposite side of the mounting bracket, the component installation position is always restricted.

Accordingly, an object of the present invention is to solve the above problems, by providing a bush mounting coupling structure that improves the constraint of the installation position of the component by configuring the component can be bushed without being in close contact with the bolt head opposite side of the mounting bracket. Is in.

In order to achieve the above object, the present invention is a bush coupling mounting including a mounting bracket which is fixed to the body and the first and second coupling holes are opposed to each other so as to have a diameter different from each other, and a component inserted into the mounting bracket and coupled to the bolt. In structure,

Among the first and second coupling holes, the bush is formed between the bush and the mounting bracket to be inserted into the first coupling hole having a larger diameter and to be screwed on the opposite side of the head of the bolt. Accordingly characterized in that it comprises a stopping means configured to prevent the bush from rotating.

1 and 2 are cross-sectional views and exploded perspective views of the bush coupling mounting structure according to the present invention. The first and second coupling holes 52 and 53 are formed to face the mounting bracket 50 and are different from each other in diameter. The screw hole 1 is formed to be inserted into the first coupling hole 52 having a larger diameter among the first and second coupling holes 52 and 53 and to be screwed on the opposite side of the head of the bolt 56. A stopping means formed between the bush 2 and the bush 2 and the mounting bracket 50 and configured such that the bush 2 does not rotate as the bolt 56 rotates, and the bolt 56 The through hole 54 is formed so that the through-hole 54 is comprised.

Said stopping means is attached to the mounting bracket 50 so that the said flange 2 formed in the outer end of the said bush 2 and the surface part of the said angled flange 3 contact and the bush 2 does not rotate. It is comprised by the latching part 4 extended.

That is, in the state in which the parts 55 are inserted between the engaging arms 51 of the mounting bracket 50, the bolts 56 are connected to the first and second coupling holes 52 and 53 and the through holes 54. ) And the bush (2) on the opposite side of the head portion of the bolt (56) by screwing the bolt (56) and the screw hole (1) while inserting the bush (2) in the first coupling hole (52). ) Is positioned.

Referring to the operation and effect of the present invention as described above, while placing the component 55 between the engaging arms 51 of the mounting bracket 50, the first and second coupling holes 52, 53 and the through hole described above The bolt 56 is inserted into the 54.

When the bolt 56 is inserted, the above-mentioned parts 55 and the mounting bracket 50 are in a pre-assembled state, so that the bush 2 is screwed to the bolt 56 and the bolt 56 is continuously rotated. do.

As the bolt 56 continues to rotate, the bolt 56 pulls the bush 2 into the engagement arm 51 so that the tip of the bush 2 gradually comes into close contact with the component 55. do.

When the bush 2 is in close contact with the component 55, the opposite side of the bush 2 is in close contact with the mounting bracket 50. At this time, the square flange 3 of the bush 2 is mounted. By being caught by the locking portion 4 of the bracket 50, the bush 2 is not rotated and the component 55 is pushed.

That is, since the bush 2 is not rotated while the surface portion of the square flange 3 is in close contact with the engaging portion 4 of the mounting bracket 50, the bolt 56 is continuously rotated. In this case, the bush 2 is pushed toward the component 55 side.

When the bush 2 is pushed toward the component 55 side, the component 55 is in a state of being in close contact with the bush 2 opposite side of the mounting bracket 50.

That is, the conventional bush 57 is located on the head side of the bolt 56 so that the component 55 is in close contact with the right side (in Fig. 1) of the mounting bracket 50, but the bush of the present invention described above ( 2) the parts 55 are brought into close contact with the left side of the mounting bracket 50, so that the relative positions of the parts 55 and the mounting bracket 50 can be changed.

When the relative positions of the component 55 and the mounting bracket 50 can be changed, the layout of the component 55 and the mounting bracket 50 can be substantially freed. .

As described above, the present invention is advantageous in that the degree of freedom of the layout of the parts and the mounting bracket is improved by installing the bush to press the parts on the opposite side of the head of the bolt while screwing the bolt to the part and the mounting bracket. .
