In order that those skilled in the art will better understand the present invention, the following further description is provided in conjunction with the accompanying drawings and examples. It is to be understood that the described embodiments are merely a few embodiments of the invention, and not all embodiments. The embodiments and features of the embodiments of the invention may be combined with each other without conflict.
Referring to fig. 2, the method for mounting an acoustic sheet according to an embodiment of the present invention includes the following steps: s1, establishing a cylinder actual model and a three-dimensional theoretical model comprising a cylinder and a mounting seat in three-dimensional software; s2, coupling the actual cylinder model with the three-dimensional theoretical model to obtain the position of the mounting seat in the actual cylinder model; s3, positioning the mounting seat 20 on the cylinder 10, and fixing the mounting seat 20 at a corresponding position in the cylinder 10; s4, the silencing sheet 30 is transported into the cylinder 10 and mounted on the corresponding mounting seat 20.
In step S1, the profile of the cylinder 10 is measured by a laser tracker multi-station layout measurement method with the manufactured cylinder 10 as a reference, so as to establish a cylinder actual model in the three-dimensional software and find an actual central axis of the cylinder actual model. And establishing a three-dimensional theoretical model comprising the cylinder and the mounting seat in three-dimensional software by taking a design drawing of the silencing equipment as a reference, and finding out a theoretical central axis of the three-dimensional theoretical model.
In step S2, the actual cylinder model is coupled to the three-dimensional theoretical model, specifically, the actual central axis of the actual cylinder model coincides with the theoretical central axis of the three-dimensional theoretical model, so that the position of the mounting seat in the three-dimensional theoretical model in the actual cylinder model can be accurately and quickly obtained.

According to the mounting method of the silencing piece, provided by the embodiment of the invention, the actual cylinder model and the three-dimensional theoretical model are established in the three-dimensional software, and the two models are coupled to accurately obtain the position of the mounting seat in the actual cylinder model, so that the position of the mounting seat on the cylinder can be accurately positioned, the problem of low positioning precision of the mounting seat caused by high measurement precision control difficulty in the prior art is solved, the positioning precision of the mounting seat 20 is ensured, and the mounting precision of the subsequent silencing piece 30 is improved.
The noise elimination sheet 30 in the invention is designed and manufactured by an outsourcing unit, and the manufactured noise elimination sheet 30 is not provided with a hanging point for hoisting, and the reason is that:
1. the structure of the silencing sheet 30 is an internal supporting frame, a honeycomb core is arranged between the frames, and the supporting frame and the outer layer of the honeycomb core are integrally coated by micro-perforated holes with the thickness of 0.8mm, so that the silencing sheet 30 is integrally of a thin-wall structure. If lifting lugs, lifting rings or lifting lug holes and other lifting points are arranged on the silencing sheet, the lifting points can only be arranged at the top of the silencing sheet, so that the lifting space is limited, and the silencing sheet is easy to damage during lifting.
2. After the noise reduction sheet 30 is manufactured, surface processing traces need to be thoroughly cleaned, the surface cannot be provided with counter-flow steps, protrusions, pits or grooves, the downstream steps are not larger than 0.2mm, and the precision requirement is high. If lifting lugs, lifting rings or lifting lug holes and other lifting points are arranged on the silencing sheet, the precision of the silencing sheet is influenced, and in the later use process, high-speed airflow passes through the lifting lug holes to generate squealing, so that the silencing function of the silencer is further influenced.
In order to mount the silencing sheet 30 in place in the cylinder 10 by hoisting, preferably, in step S4, the method for transporting the silencing sheet 30 into the cylinder 10 includes the following steps: a longitudinal hoisting device 40 and a transverse hoisting device 50 are arranged in the cylinder body 10; firstly, connecting the silencing sheet 30 with a longitudinal hoisting device 40 through a hoisting tool 60, and controlling the longitudinal hoisting device 40 to hoist the silencing sheet 30 to a preset position along the longitudinal direction of the cylinder; and then the silencing sheet 30 is connected with the transverse hoisting device 50 through the hoisting tool 60, and the transverse hoisting device 50 is controlled to hoist the silencing sheet 30 to a preset position along the cylinder body transversely.

In this embodiment, the connecting member 602 includes a first bolt 604 passing through the two lifting rods 601, and a first nut 605 connected to an end of the first bolt 604. The lifting rods 601 are provided with through holes for the first bolts 604 to pass through, after the silencing sheet 30 is placed between the two lifting rods 601, the two lifting rods 601 are close to each other by screwing the first nuts 605, and then the silencing sheet 30 can be clamped by the two lifting rods 601.
The number of the hoisting belts 603 is at least two, the at least two hoisting belts 603 are arranged at intervals along the length direction of the hoisting rods 601, and two ends of each hoisting belt 603 are respectively connected with the two hoisting rods 601. The length of the lifting belt 603 is set according to the height of the silencing sheet 30, so that when the silencing sheet 30 is lifted by the silencing sheet lifting tool, the lifting rod 601 is located between the gravity center of the silencing sheet and the top of the silencing sheet, the silencing sheet 30 can be prevented from overturning in the lifting process, and the lifting stability is ensured.
