Description
Technical field
This utility model is related to a kind of device that sample block is tested for cutting soft bubble class, and in particular to a kind of to be used to control sound
The device of soft bubble class sample block thickness and removal surface skining in impedance tube test is learned, belongs to car acpistocs technical field of measurement and test.
Background technology
At present in automotive upholstery field, front wall, carpet the soft foam material consumption such as PU in ascendant trend year by year, as PU with
The utilization rate of EPDM, EVA and felt combination is also constantly rising, while main engine plants are to PU class front walls, the acoustics of carpet product
The requirement more and more higher of performance, so very high for the requirement of test PU class exemplars.As PU plate sample workpieces are in foaming process
PU surfaces can generate one layer of closely knit air-locked epidermis, and this layer of epidermis affects very big for the test of impedance tube sound absorption, test knot
Fruit can not truly reflect the acoustical behavior of PU materials, and the bonding of PU epidermises is more firm, and excision manually can also consume plenty of time and appearance
Fragile exemplar, so it is particularly important to make a kind of cutting means for soft bubble class exemplar.
The content of the invention
The purpose of this utility model is to overcome above-mentioned weak point, there is provided a kind of to test sample block for cutting soft bubble class
Device.
According to the technical scheme that this utility model is provided, a kind of device that sample block is tested for cutting soft bubble class, including bottom
Seat, left sleeve, right sleeve, positioning screw；Locating slot is provided with the base, side is additionally provided with a square opening, determining in base
In the groove of position, symmetrical left sleeve and right sleeve are provided with, left sleeve and right sleeve can be moved in locating slot；The left side
Sleeve and right barrel forward end are equipped with positioning screw, and positioning screw can be moved in square opening.
The symmetrical graduation apparatus being provided with below the square opening of the base in units of millimeter.
The positioning screw is positioned by being coordinated with wing nut.
It is interference fits between the base and left sleeve, right sleeve.
Coordinate for gap between the positioning screw and square opening.
Described device also includes the independent cutter for cutting.
The beneficial effects of the utility model：This utility model can more effectively remove soft bubble class surface skining, and can protect
The smooth of surface is held, for the experiment sample block for having special thickness to require, this utility model also can precise control sample block thickness.With it is existing
There is manual processing scheme to compare, this utility model greatly reduces the impedance tube experiment early-stage preparations time, improves impedance tube reality
The efficiency tested.

Specific embodiment
As shown in the figure：It is a kind of for cut it is soft bubble class test sample block device, including base 1, left sleeve 2, right sleeve 3,
Positioning screw 4；Locating slot 1-1 is provided with the base 1, side is additionally provided with a square opening 1-2, in the locating slot 1-1 of base 1
It is interior, symmetrical left sleeve 2 and right sleeve 3 are provided with, left sleeve 2 and right sleeve 3 can be moved in locating slot 1-1；Institute
State left sleeve 2 and 3 front end of right sleeve is equipped with positioning screw 4, positioning screw 4 can be moved in square opening 1-2.
The symmetrical graduation apparatus being provided with below the square opening 1-2 of the base 1 in units of millimeter.
The positioning screw 4 is by being positioned with nut screw connection.
It is interference fits between the base 1 and left sleeve 2, right sleeve 3.
Coordinate for gap between the positioning screw 4 and square opening 1-2.
Described device also includes the independent cutter 5 for cutting.Cutter 5 is conventional knife, needed for changing as needed
Cutter model.
When this utility model is used, step is as follows：
The first step, soft bubble class experiment sample block is placed on inside left sleeve 2 and/or right sleeve 3, and is pushed into top, if only needing
Surface skining to be cut, then have only to be placed in single sleeve.
Second step, requires to adjust the distance between left sleeve 2 and right sleeve 3 according to sample block size, on correspondence graduation apparatus
Scale accurately cuts size controlling sample block；If only needing to cut sample block surface skining, sample block is allowed only to expose epidermis.
3rd step, size are adjusted after finishing, and the wing nut screwed on positioning screw 4 fixes left and right sleeve.
4th step, cutter knife are adjacent to sleeve surface, cut sample block vertically downward.
5th step, after the completion of exemplar cuts, unscrews wing nut, exemplar residue concludes device above cleaning plant.
In sum, this utility model patent is used to cut the device that the soft bubble class of impedance tube tests sample block, quickly can process
Soft bubble class experiment sample block surface skining, requires according to different experiments, can be accurately positioned to control sample block desired thickness size.The dress
Put and solve the problems such as soft bubble class experiment sample block preliminary preparation wastes time and energy during impedance tube is tested, it is ensured that soft bubble class sample block
Test data of experiment be consistent with Material acoustic performance.
