Problems solved by technology

When the thrust plate is assembled upside down, the oil passage groove of the thrust plate faces the main bearing housing, and the reserved oil passage with the rotating crank surface is missing, so that the oil film cannot be established between the thrust plate and the rotating crank surface
Cause poor cooling and lubrication, resulting in faults such as main bearing bushing

Embodiment 1

[0026] Example 1, the thrust plate (10) is pre-assembled between the thrust plate seat (1) and the guide bar (3) of the installation tool, so that the oil groove of the thrust plate (10) and the guide bar ( 3) Cooperate; fix the thrust plate on the installation tool by the magnetic force of the magnetic rod (6), then install the installation tool on the main bearing seat, and use the positioning pin (4) to match the fastening bolt hole of the main bearing seat Positioning, after the installation tool is fully seated, press down on the handle (9), the handle (9) drives the guide bar (3) to transmit the thrust to the pressure block (5), and finally the pressure block (5) connects the thrust plate (10) with the installation The tools come apart to complete the assembly.

Embodiment 2

[0027] Embodiment 2, an error-proof method for engine thrust plate assembly, the main working principle is that the gap distance between the guide bar (3) and the thrust plate seat (1) determines the only correct direction for the assembly of the thrust plate (10), and the assembly When the guide bar (3) cooperates with the groove (12) of the thrust plate (10), the assembly is completed by pressing down the handle (9). The distance between the guide bar (3) and the thrust plate seat (1) determines the only correct direction for the assembly of the thrust plate (3). The guide bar (3) cooperates with the groove (12) of the thrust plate (10) to guide The bar (3) acts as a guide for the thrust plate (10); the thrust plate (10) is adsorbed and fixed by the magnetic rod (6) during pre-assembly.

Embodiment 3

[0028] Embodiment 3, an anti-error device for engine thrust plate assembly, including thrust plate seat, guide bar pin, guide bar, positioning pin, pressure block, magnetic rod, pressure spring, push rod, handle, thrust plate, connecting Screw holes, grooves, screw holes, and mounting holes are characterized in that the bottom end of the thrust plate seat (1) is equipped with a positioning pin (4), the top of the thrust plate seat (1) is equipped with a handle (9), and the thrust plate seat (1) is equipped with a handle (9). (10) Installed in the bottom semi-circular opening of the thrust plate seat (1), the thrust plate (10) is installed under the magnet bar (6) and the pressure block (5), the thrust plate (10) has a concave Groove (12), groove (12) assembly guide bar (3), guide bar (3) inserts groove (12), push rod (8) is equipped with magnetic bar (6) under, push rod (8) bottom The threaded section is screwed into the screw hole (13) of the pressure block (5), the threaded ...

Abstract

The invention discloses an error-proofing method for engine thrust plate assembly, which comprises a thrust plate seat, a guide bar pin, a guide bar, a positioning pin, a pressure block, a magnetic rod, a pressure spring, a push rod and a handle, and is characterized in that through the gap distance between the guide bar and the thrust plate seat, the only correction direction for thrust plate assembly is decided, the guide bar arranged on the thrust plate seat plays guide and lead roles on the trust plate, and thus the error-proofing purpose in the case of thrust plate assembly can be achieved. The guide bar and the groove in the thrust plate are matched, the handle is pressed downwardly to push the pressure block to move downwardly, the thrust plate and the thrust plate seat are seperated and assembly is completed.

Description

technical field [0001] The invention relates to a method for preventing mistakes in assembling engine thrust plates. Background technique [0002] In the engine manufacturing industry, especially the assembly of engine internal parts will directly affect the performance and quality of the whole machine. When assembling the thrust plate of the thrust gear, the direction of the thrust plate may be easily reversed. When the thrust plate is assembled upside down, the oil passage groove of the thrust plate faces the main bearing housing, and the reserved oil passage with the rotating crank surface is missing, so that the oil film cannot be established between the thrust plate and the rotating crank surface. Causes poor cooling and lubrication, which leads to failures such as main bearing bushing. In order to effectively prevent the occurrence of such engine failures, it is urgent to design and manufacture a feasible and effective method for assembly. Contents of the invention...
