Abstract

The present invention has been invented as a tool for assembling the engine of an automobile engine so that the piston can be assembled to the engine cylinder as it is without causing excessive force and impact on the compression ring and the oil ring part assembled at the piston land part. In the automobile maintenance industry, when the engine piston is assembled and disassembled in the process of assembly, the engine piston assembly is not only shortened the working time but also prevents the piston ring from being damaged.

Description

Engine piston assembling tool

The present invention not only shortens the working time when assembling the engine piston in the engine piston disassembly and assembly work, but also enables precise and smooth assembly while preventing damage to the piston ring.

Generally, when assembling the engine piston in the automobile maintenance industry, the piston ring is used by hand or when the piston ring is mounted on the piston land, or the piston ring or oil ring is cracked or the ring film is peeled off. Fatal problems often occur.

Therefore, the present invention has the purpose of performing a complete piston assembly process and shortening the process time when assembling the engine piston, including the piston compression ring and the oil ring to prevent cracking and peeling of the ring film mounted on the piston land when assembling the engine piston.

The present invention penetrates up and down through the body placed on the top of the cylinder block in order to assemble the engine piston in the cylinder, the upper side is formed with a diameter larger than the diameter of the engine cylinder is formed an inlet for the engine piston is injected and the lower side is the engine cylinder It is formed with the same diameter, characterized in that the sliding surface formed with a discharge port for guiding the engine piston to the designated engine cylinder.

The present invention has a great effect in the complete piston assembly process without the piston compression ring assembled in the piston land portion, the ring film damage of the oiling portion and the cracking of the ring portion, including the reduction of the work process time in the automobile maintenance site when the engine piston assembly. .

The present invention will now be described in detail with reference to the accompanying drawings.

As shown in Figures 1 to 4, the present invention penetrates the top and bottom of the circular or cylindrical, the upper side is formed with a diameter larger than the diameter of the engine cylinder has an inlet for the engine piston is injected and the lower side is the same diameter as the designated cylinder It is formed and has a sliding surface formed with a discharge port for guiding the engine piston to the cylinder, the inside of the cylindrical or circular body is characterized in that the upper and lower sliding surfaces are tapered in the body and mounted on the piston land when the engine piston is assembled It has great features to reduce the working time and complete piston assembly process, including piston compression ring and oil ring crack prevention and ring coating peeling.

The external shape of the engine piston assembly tool is formed with a round or cylindrical body (No. 3), and a handle (No. 9) for supporting the piston assembly tool, including the direction of the input hole (No. 10), is formed outside the body (No. 3). It is.

Engine piston assembly tool body (No. 3) The upper opening (1) of the internal structure is formed larger than the diameter of the engine cylinder is invented so that the designated engine piston (No. 5) can be put freely, and the engine piston assembly tool body ( The outlet port 4 of the lower part 3 is formed equal to the diameter of the engine cylinder. Accordingly, when assembling the engine piston, the piston (3) of the piston assembly tool is placed on the engine block, the outlet (4) and the cylinder are placed in the same position, and then the piston connected to the cylinder through the inlet (1). If you insert (No. 5), the piston ring will slide down while contacting the sliding surface (No. 2).

Then, when the upper surface of the piston (5) is hit or pressed with a conventional tool such as a rubber hammer or a round bar, the piston ring (# 8) is pushed down along the sliding surface (2), and is compressed and smoothly. Is inserted into 7).

In addition, the piston assembly tool may be invented and developed in various shapes such as a square or a square including a cylinder.

Figure 3 is a longitudinal sectional view showing a state before insertion of the engine piston.

Figure 4 is a longitudinal sectional view showing a state after the engine piston insertion.

Claims

A body placed on top of the cylinder block to assemble the engine piston to the cylinder;

Sliding surface is formed through the upper and lower through the body, the inlet is formed with a diameter larger than the diameter of the cylinder on the upper side, the inlet for the piston is introduced and the outlet side is formed with the same diameter as the cylinder on the lower side to guide the piston to the engine cylinder Engine piston assembly tool, characterized in that formed.
