Cylinder head stamping mark pressing tool and method

Abstract

The invention discloses a cylinder cover steel seal mark pressing tool. The cylinder cover steel seal mark pressing tool comprises a positioning support, a steel seal matrix supporting block, a plurality of steel seal matrixes, a pressing block and a steel seal matrix line spacing adjusting mechanism, wherein the bottom of the positioning support is fixed on the two sides of a steel seal mark partof a cylinder cover, the plurality of transversely-adjacent steel seal matrixes are fixed in the steel seal matrix supporting block side by side, the pressing block and the steel seal matrix supporting block are embedded into a notch of the positioning support, and the bottoms of the plurality of steel seal matrixes abut against the corresponding steel seal mark part to be pressed of the cylindercover; and the two sides of the lower part of the pressing block are supported in the positioning support through the steel seal matrix line spacing adjusting mechanism. The method comprises the following steps of 1) assembling the tool; and 2) sequentially pressing steel seal marks on the cylinder cover line by line. The tool is small and exquisite in structure, convenient to use and low in manufacturing cost. According to the method, the working efficiency and quality of steel seal mark pressing are greatly improved, the appearance quality of a marine diesel engine is improved, and the labor cost is reduced.

Description

technical field [0001] The invention relates to a special tool for knocking a stamp mark on a mechanical part, in particular to a special tool and a method for knocking a product mark on the side of a cylinder head, and belongs to the technical field of mechanical processing. Background technique [0002] The cylinder head is the main key part of the diesel engine, and the stamp mark needs to be struck on the cylinder head, such as figure 1 As shown, the steel stamp mark on the cylinder head 10 of the L23 marine diesel engine has five rows of 45 characters, which are: emission number, cylinder head body number, ship inspection certificate number, water test certification number and ship inspection date. Each row of steel stamp marks is composed of letters and numbers arranged according to the writing rules. The length of the steel stamp mark area that can be tapped is about 60mm, and the width is about 35mm. The font height of the steel stamp mark is 6mm, and the tapping ran...

Problems solved by technology

[0004] 1. The efficiency is low. The operator needs to select a suitable stencil from dozens of stencils, and hit them one by one with a hammer at a suitable position in the cylinder head marking area. It takes at least 30 seconds from taking out a stencil to completing the stencil knocking, which is time-consuming strenuous

[0005] 2. The quality of knocking is poor. Because the force of the artificial hammer hitting the stamped font cannot be kept consistent, the stamped logo on the cylinder head has quality problems such as uneven depth and skewed fonts; at the same time, manual operation cannot guarantee the quality of each adjacent stamped stamp. The spacing between the marks is equal, and the line spacing of each line of stamped marks is equal, which cannot achieve the uniform effect of stamped marks, and even the knocked stamped marks cannot be recognized

Poor steel stamp marks on the cylinder head seriously affect the appearance quality of the diesel engine
