Description

Technical Field

[0001] The present invention relates to the technical field of engine exhaust and muffler, and in particular to a precise installation tool and method for a high-power engine exhaust muffler assembly. Background Art

[0002] High-power engines are generally used in the fields of ships, mining, surveying, etc., where the road conditions are generally bad and the degree of bumps is generally large. The exhaust system is the part of the entire engine exhaust treatment. Due to the particularity of its function, it is generally installed at a high position on the engine, and the installation method is often stacked on the engine through multiple parts such as brackets. During the use of the engine, the vibration of the engine is generally large, and the exhaust system is at a high position, which leads to the exhaust system often vibrating due to excessive vibration, loosening of installation parts, and even falling off. This is mainly based on the bracket itself and the installation problem. Once the installation accuracy is not high, such as the traditional installation by technicians relying on the naked eye and feeling because there is no suitable auxiliary installation tool, it will naturally be inaccurately installed, and the local stress will be too large after the bolts are tightened. In addition, in the later stage of operation on mining, surveying and other road conditions, the vibration coefficient of the relevant bracket is too large, the bolts are easy to loosen, and the local shell is torn. And some use existing measuring tools for installation to improve the installation accuracy. Not only can it not be used normally due to the limited space of high integration, but the operation is cumbersome and not conducive to industrial assembly operations. Summary of the invention

[0003] In view of the above technical problems, the present invention provides a precise installation tool and method for a high-power engine exhaust muffler assembly with high assembly efficiency, simple operation and high installation accuracy.

[0004] To achieve the above object, the present invention adopts the following technical solution:

[0006] Furthermore, a verticality distance detector is respectively provided on the rear side and the left side of the U-shaped groove; the verticality distance detector comprises a connecting seat, on which connecting bolts are distributed; one side of the connecting seat is connected to a telescopic arm support rod, and a telescopic arm slot is provided inside the telescopic arm support rod; a spring and a telescopic arm are distributed in the telescopic arm slot; the spring presses the telescopic arm outward, and a tightening bolt is correspondingly distributed at the outer end of the telescopic arm slot, and the tightening bolt is used to press and fix the telescopic arm; the outer end of the telescopic arm is rotatably connected to a verticality detection block through a rotating shaft.

[0007] Furthermore, the verticality detection block is in the form of a rectangular column structure, and a transparent angle ruler is provided on the inner side thereof.

[0008] Furthermore, the telescopic arm is provided with a scale line corresponding to the transparent angle ruler, and the telescopic arm is also provided with a telescopic degree scale.

[0009] The application method of the precision installation tool for the exhaust muffler assembly of a high-power engine using the above-mentioned method comprises the following steps:

[0010] (1) Pre-install the muffler bracket on the engine body, then tighten the bracket bonding plate to the muffler bracket by tightening the bolts and selecting the corresponding bracket fixing holes, then the exhaust pipe joint is distributed in the U-shaped groove, and then the circular concave hole of the exhaust pipe joint cap is inserted into the exhaust pipe joint, and the outer rectangular plane of the exhaust pipe joint cap faces the verticality distance detector;

[0011] (2) Then, the relative verticality between the muffler bracket and the exhaust pipe joint in the front, back, left, and right directions is detected and determined; the tightening bolt of the verticality distance detector is unscrewed, and the telescopic arm is extended by the spring force, and then the side of the verticality detection block is pressed and pressed against the rectangular plane of the exhaust pipe joint cap. If the exhaust pipe joint is relatively not vertical, it will be manifested as the exhaust pipe joint cap tilting, and then the verticality detection block is rotated relative to the telescopic arm, and the scale line and transparent angle ruler can be used to visually see which direction it tilts and how much it tilts, and then the exhaust pipe joint is adjusted accordingly until it is vertical in the front, back, left, and right directions;

[0012] (3) The distance between the muffler bracket and the exhaust pipe joint is determined by the respective telescopic scales on the vertical distance detector. If it is greater than or less than the standard scale of the telescopic scale, the front, rear, left, and right straight-line distances of the muffler bracket or the exhaust pipe joint are adjusted accordingly to achieve precise adjustment and installation.

[0013] (4) Finally, tighten the relevant bolts and tighten the exhaust pipe semicircular clamp to complete the precise installation.

[0014] The beneficial effects of the present invention compared with the prior art are as follows:

[0015] (1) In order to solve the problem of installation accuracy, this precision installation tool is provided with a bracket bonding plate to simulate the assembly of the muffler installation body, and then the exhaust pipe joint cap and the verticality distance detector are coordinated to achieve precise alignment of the exhaust pipe joint with the muffler bracket and the muffler, thereby preventing the occurrence of excessive local stress due to inaccurate installation after the traditional installation torque is tightened, and preventing the occurrence of loose bolts, large vibration or partial shell tearing due to long-term bumpy operation in mining, surveying and other road conditions.

[0016] (2) The present assembly method can realize the rapid, efficient and intuitive measurement of the verticality and spacing between the muffler bracket, the muffler and the exhaust pipe joint (circular pipe), and is convenient for the compression installation of the exhaust pipe joint in combination with the exhaust pipe semicircular clamp. For the assembly components of the special muffler bracket and the exhaust pipe semicircular clamp, the traditional problems such as local stress elimination, low vibration during operation, and low incidence of local shell tearing can be eliminated after assembly, and the use effect is good.
