Embodiment 1

[0043] In a first embodiment, such as figure 2 , The present invention is provided on the table 10, the table 11, the positioning unit 12, the annular spacer 13, the slide positioning means 14 of an apertured tube assembly tooling muffler 1, the perforated tube 1 muffler assembly tooling including and a power drive device 15, the seat 12 is positioned so that the outer perforated tube muffler tube and the inner tube 2 1 of 4 concentric annular spacer 13 for adjusting the perforated tube of the muffler outer tube 1 and inner tube 2 4 relative axial height. The slide positioning means 14 for determining the relative position of the baffle within the muffler 1, 3 within the outer tube 2 in the perforated tube, the powered device 15 is used to overcome inner tube and the outer flap 3 2 and the inner tube 4 through the clearance fit or an interference fit results in resistance to downward movement, to achieve the axial positioning of the shutter 3.

Embodiment 2

[0056] Please refer to Figure 5-6 ,in, Figure 5 An apertured tube muffler assembly of the present invention a tooling structure diagram, Image 6 for Figure 5 I in an enlarged partial section of FIG.

[0057] In a second embodiment, all structures provided in Example 1, but the embodiment is provided in the form of an annular positioning and configuration of the separator.

[0058] In particular, the annular positioning on the number of the positioning projections 12 a plurality of 1203, all of the annular positioning boss 1203 coaxially disposed, but different radii, concentric annular ring structures are formed. Corresponding adjacent two of the annular positioning boss 1202 is formed an annular groove 1203 between the innermost annular projection 1203 is positioned inside a circular groove 1202 is formed, thus positioning seat number 12 on the annular recess 1202 of a plurality of, with the use of a variety of specifications of the perforated tube positioned muffler 1 and the ou...

Abstract

The invention discloses an assembly tool for a perforated pipe silencer. The whole assembly tool is arranged between an upper workbench and a lower workbench, specifically, the assembly tool comprises a positioning seat and a sliding block positioning device, and the positioning seat can guarantee positioning of the perforated pipe silencer in the circumferential direction. The sliding block positioning device can overcome resistance caused by interference fit or clearance fit between an inner baffle and an outer circular pipe and between the inner baffle and an inner circular pipe to move downwards under the action of power driving equipment, and then the inner baffle is installed at the set position. By means of the assembly tool, the assembly precision of the perforated pipe silencer can be improved, and the consistency of mass production of the perforated pipe silencer is improved. Meanwhile, the perforated pipe silencer assembly tool can be universalized, the manufacturing requirements of perforated pipe silencers of different specifications are met, and time waste caused by tool replacement is reduced.

Description

Technical field [0001] The present invention belongs to the field of fluid machinery vibration and noise reduction, to a perforated tube muffler assembly tooling. Background technique [0002] Perforated tube muffler effective low frequency noise, wide frequency range noise, small pressure loss, high cleanness itself, reducing the risk of impurity introduction system, widely used in the field of noise rotary machine piping system. An apertured structure diagram as Muffler figure 1 Indicated. like figure 1 As shown in a perforated tube muffler 1 includes an outer tube 2, the inner tube 4, the inner flap 3 outer flap and 5, the inner tube 4 and outer tube 2 disposed coaxially, there is provided therebetween the baffle 3 and the outer plate (5), the perforated tube muffler 1 is mainly based on the principle of Helmholtz resonator, the resonant cavity enclosed volume of a great impact on the noise reduction effect of the muffler assembly precision perforated tube 1 of a higher requir...
