Description

Mounting jig for spring test.

The present invention relates to a mounting jig for spring testing, which is not limited in more detail, but is installed on both sides of the front suspension of a vehicle to test the performance and characteristics of the spring for circulating the impact from the road surface. It relates to a spring test mounting jig used for holding.

In general, a vehicle is provided with a suspension system to alleviate the shock or vibration received from the road surface while driving to improve the riding comfort and stability of the vehicle. Such suspension is usually provided by controlling the natural vibration of the spring and the spring. A shock absorber for improving the performance, and a stabilizer for preventing rolling of the vehicle. The suspension of such a general structure is shown in FIG. 1, and in FIG. 2 the spring used for the suspension is shown in detail.

According to FIGS. 1 and 2, the suspension device 1 comprises a coil spring 2, a shock absorber 3 and a stabilizer 4 as described above. In particular, the coil spring 2 should maintain proper strength and elasticity, so the performance and characteristics of the spring should be checked before installation or during use.

However, conventionally, when testing the strength or characteristics of such a spring, since the performance is directly tested in the state where the entire suspension system or the spring is installed in the shock absorber, it occupies the installation space excessively, and it is difficult to install only the spring firmly and precisely. There was a problem that can not accurately measure its own performance and characteristics.

Therefore, the present invention has been devised to solve such problems, and an object of the present invention is to provide a mounting test jig that can be firmly fixed at the top and bottom of the spring to accurately measure the strength and characteristics of the spring. have.

This object is achieved by a preferred embodiment of the present invention, according to one aspect of the present invention, in the spring test mounting jig for fixing the spring at both sides in the characteristic test of the spring, a horizontal central portion inserted into one side of the spring It is formed along the periphery of the horizontal center portion, the front end portion is formed on the same plane as the horizontal center portion and the lower end portion, and one side of the spring includes a seating portion is formed with the end portion is fixed to the side end portion, and a support surface formed with a fixture in the center A first jig; And a horizontal center portion inserted into the other side of the spring, a front end portion formed along a circumference of the horizontal center portion, and a lower end portion formed lower than the horizontal center portion, and a seating portion formed at a lower portion of the front end portion and having an end to which the other end portion of the spring is fixed. A second jig including a support surface on which is formed; It is provided with a mounting jig for the spring test, characterized in that consisting of.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

3A and 3B are perspective views showing the first jig and the first jig of the mounting jig for testing according to the present invention, respectively, and FIGS. 4A and 4B show the first jig of the mounting jig for testing according to the present invention. A side view of each of the jig and the second jig is shown, and FIG. 5 shows a state diagram of use of the spring mounted state.

According to Figures 3A, 3B, 4A, 4B and 5, the spring test mounting jig according to the present invention includes a first jig 10 and a second jig 20. Generally, one side of the spring S is supported by the first jig 10, and the other side of the spring S is supported by the second jig 20.

In more detail, the first jig 10 includes a spring seating portion 12 that is suitably cut to one side of the spring S that is helically mounted or mounted around the central upper surface 11. In addition, a support surface 13 is formed on the opposite side of the central upper surface 11, for example, supported by dies D of various test apparatuses, and the die D is formed at the center of the support surface 13. A fastener 14 is formed which is inserted into and fixed in the fixing hole drilled in the hole. In particular, the width of the seating portion 12 is preferably proportional to the diameter of the spring (S).

Of course, the front end portion 12a of the seating portion 12 is preferably located on substantially the same plane as the central upper surface (11).

In addition, the second member 20 is formed similarly to the first member 10, and the second member 20 has a central upper surface 21 similarly to the first member 10, and its circumference The spring seating portion 22 is inserted into the other side of the spring (S) is formed. Of course, on the opposite side of the central upper surface 21, a fixture 24 is mounted to a fixing member (not shown) of the spring test apparatus.

In addition, the width of the seating portion 22 is also similar to the diameter of the spring.

In particular, the tip portion 22a of the seating portion 22 of the second jig 20 is preferably located below the central upper surface 11.

This is to prevent the phenomenon of being separated from the spring without any fixing means in the state inserted into the other side of the spring (S).

In the manner of fixing or mounting the spring to the jig using the mounting jig according to the present invention, when fixing one side of the spring with the first jig 10, the fixing hole of the die (D) not shown in detail The fastener 14 formed in the support surface 13 is fixed to it. Thereafter, one side of the spring S is seated and fixed to the seating portion 12 formed around the center upper surface 11, wherein an end of one side of the spring S is terminated at the seating portion 12. One side portion is fixed in contact with the seating portion 22 in a fixed state in contact with the portion 12b. In this state, the second jig 20 is inserted into and fixed to the upper central upper surface 21 of the spring S.

The fixture 24 formed on the support surface 23 of the jig 20 can be held in a state of being fixed to a test apparatus (not shown) or its fixing member in advance.

In addition, the end of the other side of the spring (S) is in contact with the seating portion 22 in a fixed state in contact with the end portion 22b of the second jig 20 and the spring is placed in a manner that is past the tip portion 22a. It is mounted on the mounting jig. Accordingly, when actually measuring the strength and characteristics of the spring, even if the spring S is repeatedly compressed and released in a limited stroke range, the spring S does not deviate from the zig rotor.

As a result, when the spring is fixed using the spring test mounting jig according to the present invention, each end portion of one side and the other side of the spring is formed at the end of each seating portion of the first jig and the second jig and the end of the seating portion. Since it is fixed to the spring, rocking and separation of the spring are prevented, so there is a good retention.

Although a preferred embodiment according to the present invention has been described above, it will be understood by those skilled in the art that various modifications and changes can be made without departing from the scope of the appended claims.
