Abstract
The utility model provides a novel sleeve of making an uproar falls, includes non - metal coat, and damping material inlayer, cubic metal inner core and hexagonal metal inner core, non - metal coat have a wide section and a narrow portion, and this hexagonal metal inner core sets up in this wide section, and this four directions metal inner core sets up in this narrow portion, and the space between this non - metal coat and this four directions and the hexagonal inner core is provided with the damping material inlayer. This novel sleeve of making an uproar falls is different with the current structure by metal material integrated into one piece, but adopts split type structure, and the middle dielectric material who adopts a shock attenuation attraction plays the cushioning effect as the damping material inlayer, can show the reduction noise when using.
Description
Technical field
This utility model relates to auto industry and mechanical manufacturing field, particularly to the noise-reducing sleeve of the reduced noise used when assembling different size standard component (screw) on assembly line.
Background technology
On modern production assembly line when build-up member screw connects fastening, it is necessary to use Pneumatic sleeve to complete to install.One end of sleeve and the rifle head docking of pneumatic four directions, the other end of sleeve needs and screw to be installed docking.
Current distinct issues be metal sleeve in use, sleeve and screw part to be installed impact due to pneumatic shock and friction and deafening noise occur, and serious infringement worker is physically and mentally healthy.Therefore, based on the problems referred to above, it would be highly desirable to research and development can reduce the noise-reducing sleeve of noise to greatest extent.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of Novel noise reduction sleeve.
For solving above-mentioned technical problem, this utility model realizes as follows:
A kind of Novel noise reduction sleeve, including nonmetal overcoat, damping material internal layer, quadratic metal inner core and six side's metal insides, nonmetal overcoat has a loose portion and a narrow portion, this six sides metal inside is arranged in this width portion, this quadratic metal inner core is arranged in this narrow portion, and the space between this nonmetal overcoat and this four directions and six side's inner cores is provided with damping material internal layer.
Of the present utility model have the benefit effect that
This Novel noise reduction sleeve is different by the integrated structure of metal material from existing, but adopts split-type structural, adopts the interlevel dielectric material that a kind of damping attracts as damping material internal layer, plays cushioning effect, can significantly reduce noise in use.
Accompanying drawing explanation
The structural representation of a kind of Novel noise reduction sleeve that Fig. 1 provides for this utility model embodiment.
Fig. 2 is the generalized section of Novel noise reduction sleeve in Fig. 1.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail.
Refer to the structural representation of a kind of Novel noise reduction sleeve that Fig. 1-2, Fig. 1 provide for this utility model embodiment.Fig. 2 is the generalized section of Novel noise reduction sleeve in Fig. 1.Novel noise reduction sleeve of the present utility model includes nonmetal overcoat 1, damping material internal layer 2, quadratic metal inner core 3 and six side's metal insides 4.
Nonmetal overcoat 1 can be made up of PVC material, and has a wide portion and a narrow portion, and the width of wide portion outline is more than the width of narrow portion outline, and the width of width portion Internal periphery is also greater than the width of narrow portion Internal periphery.This six sides metal inside 4 is arranged in this width portion.This quadratic metal inner core 3 is arranged in this narrow portion.And, this six sides metal inside 4 and quadratic metal inner core 3 are arranged on the center in nonmetal overcoat 1, and two parts are concentric up and down.Space between this nonmetal overcoat 1 and this inner core 3 and 4 is provided with damping material internal layer 2, and this internal layer 2 can use the special damping rubber of fusing to fill then through High Temperature High Pressure shaping.
Above-mentioned parts 1-4 in process of production, all first can produce four kinds of parts with mould respectively, then with special production hot pressing die, four kinds of parts be fixed.During the use of this Novel noise reduction sleeve, quadratic metal inner core 3 and the pneumatic four directions rifle head of this Novel noise reduction sleeve narrow portion dock, and six side's metal insides 4 and the installation screw in this wide portion of Novel noise reduction sleeve dock.Then start air pressure gun to fulfil assignment.
This Novel noise reduction sleeve is different by the integrated structure of metal material from existing, but adopts split-type structural, adopts the interlevel dielectric material that a kind of damping attracts as damping material internal layer 2, plays cushioning effect.This medium composition is added or reduces, a kind of chemical composition of mixing, vulcanizing treatment improves flexibility and the fatigue strength etc. of hardness and material, carry out High Temperature High Pressure hot melt adhesion, structural outer have employed novel nonmetallic materials, realize Split type structure and be again combined into entirety, meet the technology requirement to moment of torsion of many specifications kind.
The noise in Assembling Production workshop 50% is all that Pneumatic sleeve produces, and each station noise level also differs, and uses noise-reducing sleeve through on-the-spot noise reduction detection contrast, it is possible to decrease to make an uproar about 15%, played huge effect in noise pollution improvement.Due to the change of the structure of sleeve and material, also mitigate the weight of sleeve simultaneously, decrease the labor intensity of workman,
This utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but in its shape or structure, do any change; every have same or like with this utility model like technical scheme, all fall within protection domain of the present utility model.
