4. The mounting method for preventing the failure of the tolerance adjusting member between the sheet metals according to claim 3, wherein: the outer diameter of the core rod is 0.05-0.1 mm larger than the outer diameter of the tolerance adjusting piece inserted bolt.

Technical Field

The invention mainly relates to the field of tolerance adjustment, in particular to an installation method for preventing a tolerance adjustment part between metal plates from failing.

Background

The part is installed between two panel beating, adjusts the problem of the clearance size between panel beating through the method of bolt screw in part, however, this kind of method can lead to the adjusting part can't rise automatically, can't compensate the problem of clearance between panel beating and the panel beating.

According to the illustration of fig. 1, the arrow indicates the connecting surface. When the device is not installed, if the two surfaces are attached without gaps, the friction force is too large. Furthermore, the adjustment part cannot be lifted up during installation due to excessive friction. Therefore, the adjuster cannot be lifted after the mounting bolt is driven.

Disclosure of Invention

Aiming at the defects in the prior art, the invention provides an installation method for preventing a tolerance adjusting piece between metal plates from failing, which comprises the following steps:

the first step is as follows: installing a part between two metal plates, wherein one side of one metal plate, which is far away from the part, is provided with a tolerance adjusting part;

the second step is that: one side, far away from the part, of the other metal plate is inserted into a core rod and is inserted into an adjusting cavity of the tolerance adjusting part, and the core rod is in interference fit with a spring chuck part of the tolerance adjusting part;

the third step: adjusting the size of a gap between the metal plate and the metal plate by rotating the core rod;

the fourth step: after the core rod is rotationally adjusted, overcoming the friction force of the joint surface and automatically lifting;

the fifth step: and the tolerance adjusting piece retracts to finish the adjustment.

Preferably, the mandrel is arranged coaxially with the tolerance adjustment element.

Preferably, the core rod is a circular core rod.

Preferably, the outer diameter of the core rod is 0.5 to 0.1mm larger than the outer diameter of the tolerance adjusting member insert bolt.

The invention has the beneficial effects that: simple structure, convenient operation inserts the plug in the regulating part, and the plug external diameter is big, and rotatory back can overcome the frictional force automatic lifting of composition surface.

Detailed Description

In order to make the technical solutions of the present invention better understood and make the above features, objects, and advantages of the present invention more comprehensible, the present invention is further described with reference to the following examples. The examples are intended to illustrate the invention only and are not intended to limit the scope of the invention.

As shown in fig. 1, the present invention includes the following steps:

the first step is as follows: installing a part between two metal plates, wherein one side of one metal plate, which is far away from the part, is provided with a tolerance adjusting part;

the second step is that: one side, far away from the part, of the other metal plate is inserted into a core rod and is inserted into an adjusting cavity of the tolerance adjusting part, and the core rod is in interference fit with a spring chuck in the tolerance adjusting part;

the third step: adjusting the size of a gap between the metal plate and the metal plate by rotating the core rod;

the fourth step: after the core rod is rotationally adjusted, overcoming the friction force of the joint surface and automatically lifting;

the fifth step: and the tolerance adjusting piece retracts to finish the adjustment.

In this embodiment, the mandrel is preferably arranged coaxially with the tolerance adjuster.

By adopting the structure, the coaxial arrangement is favorable for the balance of force and is convenient for adjustment.

In this embodiment, a circular mandrel is preferably used as the mandrel.

Set up above-mentioned structure, 360 degrees of circular shape plug are all mellow, and on the one hand, insert the effect that the regulating part can play the mistake proofing, and on the other hand is convenient for lift up owing to smooth, and is more convenient.

In this embodiment, the outer diameter of the core rod is preferably 0.05 to 0.1mm larger than the outer diameter of the tolerance adjuster insert bolt.

By adopting the structure, the friction force of the joint surface can be overcome after the rotation to automatically lift by utilizing the large size of the adjusting piece.

The above-described embodiments are merely illustrative of the principles and utilities of the present patent application and are not intended to limit the present patent application. Modifications and variations can be made to the above-described embodiments by those skilled in the art without departing from the spirit and scope of this patent application. Accordingly, it is intended that all equivalent modifications or changes which can be made by those skilled in the art without departing from the spirit and technical concepts disclosed in the present application shall be covered by the claims of this patent application.
