Description

{TOOL FOR BUSHING REPLACEMENT}

The present invention relates to a bushing replacement tool, and more particularly, to a bushing replacement tool that is simple in structure and accommodates a bushing inserted in a vehicle member to simplify assembly and installation, To a work tool.

In general, a lot of bushing is required to connect parts and components in a suspension of an automobile. In the automobile, the bushing connects the components as well as the knee joints, reducing wear during perturbation between components, and absorbing shocks transmitted from the road surface to the vehicle body during self-oscillation or when driving to prevent noise and vibration. And it is essential to improve the ride quality.

There are many types of bushings used in automobiles, but a so-called rubber bushing using rubber is often used as a shock absorbing filler. Referring to Fig. 9, the bushing 1 has a structure in which two metal sleeves 2 and 3 are coaxially arranged and the rubber sleeve 4, which is an elastic body, is filled between the inner sleeve 2 and the outer sleeve 3. Wherein the inner sleeve (2) is generally longer than the outer sleeve (3). The outer sleeve 3 fits tightly in the mounting hole of the vehicle member 5, such as an automobile part, such as an arm or a plate, and is integrally fixed. The inner sleeve (2) of the bushing (1) can be bolted to the other member. The members other than the vehicle member 5 connected through the bushing 1 can be moved around the fastening bolt elements. The rubber filler 4 absorbs impact acting in any direction orthogonal to or parallel to its axis, while elastically corresponding to the movement of the two members.

If the metal sleeves 2 and 3 of the bushing 1 described above are corroded or the rubber filler 4 is lost and its elasticity is lost, it can not fulfill its function and causes a metallic noise together with a severe vibration. It is necessary to inspect it and replace it with a new one at the right time.

Replacing the bushing (1) can be done by removing the bushing to be replaced and replacing it with a new one, which is difficult, time consuming and damaging to the product, such as tapping with a hammer when removing or inserting it. I needed a tool or a jig.

In accordance with this need, the present applicant has developed a tool used for bushing replacement and applied for a patent. The applicant has been registered with the registered patent 10-1454350 "Tool for bushing replacement work" To 12, and the construction and operation of the system will be described as follows.

Referring to Fig. 10, Fig. 11 shows a work state in which the bushing 1 is pulled out from the vehicle member 5 provided with the bushing 1. Fig. The adapter 30 for a bushing support adapted to the size of the bushing 1 to be worked is placed on the receiving portion 21 of the tool body 20 and the vehicle member 5 provided with the bushing 1 to be pulled thereon is placed thereon. Then, the bushing pressing adapter 40 corresponding to the size of the bushing 1 is attached to the ram 13 of the hydraulic actuator 10. When the pressurizing oil is supplied to the hydraulic actuator 10 for operation, the ram 13 descends and the lower end of the bushing pressurizing adapter 40 attached to the bushing presses the outer side of the bushing 1 The bushing 1 is pushed out of the vehicle member 5 by the force of the ram 13 which is continuously pressed from this time and collected in the hollow portion 32 of the adapter 30 for the lower bushing support. When the bushing 1 is removed, the supply of the pressurized oil is stopped and the ram 13 is returned to complete the operation.

Next, referring to Fig. 10, Fig. 12 shows a work state in which the bushing 1 to be replaced is fitted to the vehicle member 5. 8, a new bushing 1 'to be replaced is placed on the vehicle member 5 from which the bushing 1 has been removed, and then the hydraulic actuator 10 is operated again. At this time, preferably, the bushing pressing adapter 40 Can be used for the bushing pressurizing adapter 60 for exclusive use with the truncated conical hole 61 of Fig. 7 described above.

In this operation, it is necessary to increase the position of the ram 13 in correspondence with the height of the bushing 1 'placed on the vehicle member 5, and it is necessary to rotate the hydraulic actuator 10 in the direction in which the screw- Can be easily adjusted. When the hydraulic actuator 10 is operated after completion of the preparation, the ram 13 is lowered and the bushing 1 'is pressed by the bushing pressing adapter 60 to be fitted into the mounting hole of the vehicle member 5, The inner sleeve end of the bushing 1 'is accommodated by the truncated conical hole 61 of the pressure applying adapter 60 so that the work can proceed without concern that the bushing 1' is damaged due to its natural centering.

However, the above-described conventional techniques have the following problems.

The conventional bushing replacement tool has a problem in that it takes a relatively long time and manpower to replace the bushing because the tool for replacing the bushing is structurally complex and is very inconvenient to be fixed to a vehicle.
