Engine high-voltage wire press-fitting device

Abstract

The invention relates to a press fitting device for an engine high-voltage wire. The press fitting device for the engine high-voltage wire solves the problem that in the prior art, people use a rubber hammer to hammer the engine high-voltage wire, so that the internal quality of the high-voltage wire is influenced by shock, caused by acceleration, existing inside the high-voltage wire. The press fitting device for the engine high-voltage wire comprises a pressing rod hinged to a support. A pressing head is connected to the middle of the pressing rod. The axis of the pressing head is perpendicular to the axis of the pressing rod. The pressing head is provided with a pressing surface which is in full contact with a high-voltage wire head. Since the pressing head is perpendicular to the pressing rod, when the pressing rod is rotated, the pressing head conducts downward pressing, so that the high-voltage wire head is pressed into an installation hole of an engine, and pressing is completed in a one-off mode. In the process of pressing, the pressing head is in static contact with the high-voltage wire firstly, and then the pressing rod transmits pressure; the pressing head cannot apply instant impact force on the high-voltage wire head and cannot cause acceleration shock, so that the internal quality of the high-voltage wire is not influenced. The pressing surface of the pressing head is in full contact with the high-voltage wire head, so that it is guaranteed that the high-voltage wire head is stressed evenly, and damage caused by too high partial pressure is avoided.

Description

technical field [0001] The invention relates to a tool for assembling an engine, in particular to a press-fitting device for an engine high-voltage wire that will not cause damage to the high-voltage wire. Background technique [0002] To ignite and start the engine, it is necessary to ignite the spark plug through a high-voltage wire. The high-voltage wire is wrapped by a thick layer of black rubber, which is soft in texture and is in flexible contact with the spark plug. When it is pressed into the mounting hole of the engine, when it is installed in place There is a noticeable click. [0003] The high-voltage wires on the engine belong to the plug-in assembly. When pressing the high-voltage wires, you can press and insert them with bare hands, but the resistance between the high-voltage wire head and the mounting hole is relatively large, and it needs to apply a large force when pressing with bare hands, and the pressing force is difficult. Mastery, long-term bare-handed...

Problems solved by technology

[0007] The present invention also solves the defects in the prior art that rubber hammers are used to complete the assembly of the high-voltage wires of the engine. Due to the existence of acceleration, the internal vibration of the high-voltage wires affects the internal quality of the high-voltage wires, and provides a press-fitting device for the high-voltage wires of the engine. Press the high-voltage wire head into the installation hole after making full contact with the high-voltage wire head, which will not cause vibration inside the high-voltage wire and ensure the quality of the high-voltage wire is intact

[0008] The present invention also solves the problem that in the prior art, when the rubber hammer is used to hit the high-voltage wire head, the rubber hammer cannot be controlled to be completely parallel and in plane contact with the high-voltage wire head, which causes a large local force on the high-voltage wire head and affects the internal quality of the high-voltage wire. The defect is to provide a press-fitting device for the high-voltage wires of the engine, which is in full contact with the high-voltage wires, and after contacting the high-voltage wires, apply force to press the high-voltage wires into the mounting hole to ensure that the quality of the high-voltage wires is intact
