This paper relates to a disassembly and assembly device that can easily renovate a vehicle overrun, and in particular, it effectively compresses and expands a coil spring with a strong elasticity mounted on the tip of a shock absorber. The over can be easily disassembled and assembled.

As is well known, the shock-absorber is installed to quickly absorb the rise of the spring caused by the road surface while driving the car to improve ride comfort and reduce the fatigue of the spring. There is a time when there is a burden on the shop itself, which requires renovation.

In other words, there is no difference in the automobile overshoot, but the coil spring of very strong elasticity is mounted on the outer end of the overshoot so that it can be disassembled and assembled with the oversea. When the inside of the over and the coil spring need to be replaced, there is a time when it needs to be repaired.

Therefore, in order to repair the shock absorber or coil spring, the coil spring, which has a strong elasticity, is firstly removed from the shock absorber to be separated.

In other words, to release the coil spring's elasticity and release it, release the bolt attached to the top of the shock absorber, and then disassemble it sequentially. In this way, when the bolt is released, the coil spring's elastic force is too strong. When the compressed coil springs burst and are thrown away, it is common to injure workers, and even the fatal symptom is always dangerous.

In addition, due to the strong resilience of the coil spring, it is impossible to perform the work alone, so two or more people have to work together. This also requires at least 40-60 minutes of disassembly and assembly time, except for renovation work. However, because it requires too much strength, if the physical strength is not strong, the task could not be done.

Therefore, in order to perform the operation easily, the compression extension of the coil spring must be efficiently controlled. In particular, in this paper, the efficient control of the coil spring is enabled, which will be described in detail based on the accompanying drawings as follows.

FIG. 1 is an overall perspective view of the present invention, and FIG. 2 is a state diagram in which the device parts of the present invention except for the base 1 are disassembled, and FIG. 3 and FIG. 4 show the state of the present invention viewed from the top and the side.

In the upper part of the giant 1, the front part is equipped with the mechanism of the fixing part 2 and the fixing part 3, and the rear part is equipped with the hydraulic cylinder 4 which has the head 5 at the tip of a shaft. (2) is mounted to the foremost part of the base (1), the left fixing bracket 20 and the right fixing bracket 25 is fixed to both ends by bolts, between the support brackets 13 ( 18) The upper variable cover 10 and the lower fixed cover 15 which is inclined inwardly are mounted, but the concave portion 11 of the upper variable cover 10 is on the upper side of the support plate 21 of the left fixing bracket 20. The fixed pin 43 is fixed to the rotary bracket 24, which is built up, and the fixing part 12 is introduced between the stand 26 of the rear bracket 25 and is fixed to the fixing bolt 45. The opening and closing of the fixing bolt 43 of the 4) to open and close, and the condensation part 16 of the lower fixing cover 15 is inserted into the concave part 22, the rotary bracket 24 is inserted into the shaft (24) ') And the other portion 17 is fixed to the support plate 27 as a fixing bolt 19 to allow the left and right swings by the long hole 17 ', and the right side flow bracket of the flow portion 3 35 and the left side flow bracket 30, the upper variable cover (10 ') and the lower fixed cover (15') having respective support pins (13 ', 18') are respectively condensed and fixed bolt (41) at the bottom The support plate 40 having a) is fixed as the bolt 42, the bushings 39 are inserted into the flow insertion holes 33 and 38 of the right and left flow brackets 30 and 35, respectively, and the shaft 7 is inserted into And one side of the inserted shaft (7) is inserted into the insertion hole (23, 28) of the left and right fixing brackets (20, 25) to be screwed with a nut and the other side is to be fixed to the fixing plate (5) by a nut.

The operational relationship of the proposed paper thus constructed is as follows.

In this proposal, as shown in FIG. 5, after the shock absorber 100 is opened with the upper variable cover 10 and 10 'open, the upper variable cover 10 and 10' is closed again. Will run.

The working relationship of this paper is illustrated in detail in FIGS. 6 (a), (b) and (c). As shown in (a) of FIG. 6, the coil spring 101 secured between the flow cap 103 and the fixed cap 102 of the micro-over-over 100 is fixed part 2 and the flow part ( 3) the upper variable cover (10) (10 ') and the lower fixing cover (15) of the mounting so as to engage the fastening bolts 44 of the fixing plate (43) fixing part 12 of the upper variable cover (10) Is firmly fixed and the hydraulic cylinder 4 operating switch (not shown) is turned on, the hydraulic cylinder 4 is operated as shown in FIG. 6 (b) to operate the head 15. Pushed forward. As the head 15 is pushed forward, the left and right flow brackets 30 and 35 are also advanced, thereby compressing the coil spring 101 which is coupled to the upper variable cover 10 'and the lower variable cover 15'. When the coil spring 101 is compressed, the fixing bolt 41 of the support plate 40 is fixed to the fixing passage 8 of the base 1 to be firmly fixed.

After the coil spring 101 is compressed, the left and right flow brackets 30 and 35 are firmly fixed, and then the operation switch (not shown) of the hydraulic cylinder 4 is turned on again. As shown in the drawing, the rear end of the head 5 causes the shaft 105 including the flow cap 103 supporting the spring 101 to be retracted by the internal hydraulic pressure of the shock absorber 100.

Therefore, since the coil spring 101 is in a compressed state, it is possible to disassemble the shock absorber 100 very easily by loosening the nut 104 of the shock absorber 100. In particular, even when the show-over over 100 is separated from the inside of the coil spring 101, the coil spring 101 is supported by the support pins 13, 13 ', 18 and 18', so it is not elastic and compressed. It will keep the phenomenon as it is.

After completely repairing the shock absorber 100, the coil spring 101 can be easily mounted by the shock absorber 100 when the shock absorber 100 is performed in the reverse order as described above.

In particular, in this paper, the lower fixing cover 15, 15 'is made to flow by some deviation so that it can cope efficiently with the angle of the coil spring 101 by the long hole 17' of the condensation part 17. Other shops can be easily disassembled and assembled.

Since the upper side cover 10, 10 'is rotatable by the rotary bracket 24, it is easy to cope with the spring angle of the other types of shock-over.

As discussed above, this paper is designed to be easily disassembled by applying spring angles of other types of shock-absorbers. Especially, the present invention is not only capable of carrying out the disassembly and assembly, Time can be processed in about 10 minutes, so unnecessary power is not only wasted, it is also useful to be able to significantly shorten the working time.
