Problems solved by technology

[0005] However, during the temperature field test, the installation and removal of the hardness plug is extremely critical, and the torque needs to be accurately grasped. If the force is too small, the hardness plug will fall off during the engine running.
Excessive force will cause the hardness plug to slip or crack, making it impossible to remove
The existing hexagonal wrench of φ1.5mm is used to assemble and disassemble the hardness plug, but the hexagonal wrench is easy to slip teeth, the service life is too short, the body size is too small, it is not convenient to install and disassemble the hardness plug in the inner cavity of the piston, and it cannot be extended. It is easy to use force, and the inner hexagonal wrench is usually a complete set (from φ1.5mm to φ10mm), and only the smallest (φ1.5mm) is used to install and disassemble the hardness plug, and it is discarded when it is worn out. more, waste of resources

Abstract

The invention discloses a dismounting tool for a temperature field hardness plug, which comprises: an inner hexagonal rod, on which several circles of breaking lines are arranged at intervals, and a new inner hexagonal wrench can be formed after the inner hexagonal rod is broken along the breaking line; And an extension rod, one end of the extension rod is provided with a hexagonal hole in the axial direction, and the hexagonal rod is inserted into the hexagonal hole, and the hexagonal rod and the extension rod are locked together with locking screws. The assembly and disassembly tool can prolong the service life and is convenient to use.

Description

technical field [0001] The invention relates to the field of tools, in particular to a tool for disassembling and assembling a temperature field hardness plug. Background technique [0002] As one of the key components of the engine, the operating condition of the piston is directly related to the working reliability and durability of the high-speed supercharged engine, and directly affects the emission performance of the engine. The operating environment of the piston is very harsh. First, it must bear the pressure of high-pressure gas explosion, the inertial force of extremely fast reciprocating motion, and periodic mechanical loads such as side pressure and friction; second, the top surface of the piston is subject to transient The action of high-temperature gas makes the temperature of the top of the piston and even the entire piston very high, and the temperature distribution is uneven, and the temperature gradient of each part is large, causing great thermal stress and...
