Detailed Implementation

[0019] To make the above objectives, technical solutions and beneficial effects clearer and more explicit, the present invention will be described in detail below with reference to the accompanying drawings.

[0020] like Figure 1-5 As shown, the gasoline engine water inlet pipe assembly device includes a handle 1, a copper block 2, a sliding rod 3, a sliding rod head 4, and a water inlet pipe 7; one end of the handle 1 is connected to the copper block 2, and the other end of the handle 1 is connected to the sliding rod head 4. The sliding rod 3 is inserted into the handle 1, and the water inlet pipe 7 is inserted from the left side of the copper block 2.

[0021] A countersunk hole 13 is provided through the edge of the side of the copper block 2, and a water inlet connector 14 is provided through the center of the side of the copper block 2. A first insertion interface is provided on the lower edge of the handle 1, and a lower insertion port 11 is provided through the center of the lower section of the handle 1. After the lower section of the copper block 2 and the handle 1 are aligned, the threaded hole 12 and the countersunk hole 13 are aligned and the internal hex bolt 8 is inserted. The water inlet connector 14 and the lower insertion port 11 are aligned. The water inlet connector 7 is inserted from the water inlet connector 14. The end of the water inlet connector with the expansion joint is inserted into the handle 1. After the water inlet connector 7 is inserted, the outer end of the water inlet connector 7 protrudes 1mm. The surface of the exposed end of the water inlet connector 7 is coated with sealant. The water inlet connector 7 is interference-fitted and sealed with sealant to ensure no water leakage. The copper block 2 with the water inlet connector 7 installed fits against the water inlet connector mounting hole on the engine block surface. The 1mm exposed section of the water inlet connector 7 is positioned by the chamfer of the mounting hole on the engine block surface.

[0022] The lower section of the sliding rod head 4 has a first sliding rod insertion port 15 through it, and the upper section of the handle 1 has a second sliding rod insertion port 16 through it. One end of the sliding rod 3 is inserted through the second sliding rod insertion port 16, and the other end is inserted through the first sliding rod insertion port 15. The sliding rod head 4 is installed, and after insertion, the upper end 19 of the sliding rod is inserted into the sliding rod head 4. During installation, the water inlet pipe 7 is inserted through the lower section of the copper block 2. After assembly, the lower end 17 of the sliding rod contacts the water inlet pipe 7. The operator holds the handle 1 and taps the sliding rod head 4 with a hammer until the lower section of the sliding rod head 4 is in contact with the upper end of the handle 1. The water inlet pipe 7 assembly device is then removed, and the water inlet pipe 7 assembly is completed.

[0023] The outer surface of the handle 1 is provided with a first pin hole 5, into which a first pin 9 is inserted. The first pin 9 contacts the middle section 18 of the sliding rod. The outer surface of the sliding rod head 4 is provided with a second pin hole 6, and the outer surface of the sliding rod 3 is provided with a sliding rod pin hole 20, which corresponds to the second pin hole 6. A second pin 10 is inserted into the second pin hole 6. After the sliding rod 3 is installed, it is limited by the first pin 9 and the first pin 9 inserted into the first pin hole 5.

[0024] The water inlet pipe 7 is a component on the engine and needs to be assembled onto it. The gasoline engine water inlet pipe assembly device is used for installing the water inlet pipe 7. It utilizes a sliding rod 3 and a handle 1 to enclose the water inlet pipe 7, protecting both its inner and outer walls to ensure the thin-walled water inlet pipe 7 does not deform during hammering. The handle 1 is made of steel, which has high hardness; direct contact with the machined surface of the engine block would damage it. A copper block 2 is installed on the lower section of the handle. Since copper is softer than cast iron, it protects the machined surface of the engine block from damage. The copper block 2 is installed at the contact point with the machined surface to provide a transition and avoid damage. Simultaneously, the sliding rod head 4 and the handle 1 act as a limit, effectively controlling the hammering depth and ensuring consistent hammering. This fixture allows for rapid assembly of the water inlet pipe 7, ensuring it does not deform during hammering and guaranteeing consistent hammering depth, thus improving assembly efficiency and quality.

[0025] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
