Abstract
The invention relates to a sound intensity testing bracket, which comprises a bracket base, a vertical rail, a horizontal rail and a sound intensity probe, wherein the vertical rail is vertically arranged on the bracket base; the horizontal rail is vertically arranged on the vertical rail and is arranged horizontally; and the sound intensity probe is movably arranged on the horizontal rail.
Description
Technical field
The present invention relates to belong to the NVH test of automobile industry, be specifically related to a kind of sound intensity testing bracket, in the time can not testing the sound intensity, finish the test of the sound intensity with hand-held sound intensity probe.
Background technology
The automobile industry test sound intensity, hand-held sound intensity probe is very inconvenient.And when the test engine sound intensity, noise is very big near the engine that runs up, and the people is caused the injury of the sense of hearing, and it also is breakneck doing experiment near Gao Su the engine in addition.
Summary of the invention
In view of above-mentioned inconvenience, the object of the present invention is to provide a kind of sound intensity testing bracket, make the tester can finish the test of the sound intensity away from engine or dangerous test position.
Specifically, the object of the present invention is to provide the instrument of a kind of two dimensional surface location, rely on fractional electric motor to be driven into assigned address, control the level of support and moving up and down by the operator, track is a square fluting aluminium alloy extrusions, put up scale on the aluminium alloy extrusions, put up pointer on the traversing carriage.The balancing weight of vertical direction is made vertical gyro simultaneously and is determined that support is vertical with surface level.
Concrete technical scheme is as follows:
A kind of sound intensity testing bracket, comprise bracket base, vertical track, horizontal rail and sound intensity probe, wherein, described vertical track vertically is installed on the described bracket base, described horizontal rail vertically be installed in described track vertical on, and horizontal rail is the horizontal cross setting, and described sound intensity probe is installed on the described horizontal rail versatilely.
Described bracket base is a horizontal base, and it is used to keep flat to the sound intensity to be measured position.
Described vertical track vertically is inserted and secured on this bracket base.
Described horizontal rail is connected to the track structure of vertical track by a coupling arrangement, and it is slipped into the track structure of vertical track by the top.
Also comprise a pulley blocks, it is installed in the vertical track top.
Also comprise counterweight block and stay cord, an end of described stay cord is fixed this counterweight block, and the other end is walked around described pulley blocks, and is fixed on the traction stay cord hanging hole on the horizontal rail.
Also comprise a horizontal small car, described sound intensity probe is fixed on this horizontal small car, and described horizontal small car is fixed on the horizontal rail, and it is dynamically connected to the track structure of horizontal rail by outside slip.
Described horizontal small car is provided with a motor, and being used to of this motor drives moving of horizontal small car.
Described horizontal rail connects vertical track one side and/or horizontal small car is provided with position indicator pointer, and described vertical track and/or horizontal rail are provided with the set scale label of correspondence position pointer.
Also be provided with a camera, this camera is used to observe the scale label of personnel's observation position pointer correspondence.
Compare with present prior art, the present invention is semi-automatic adjusting support, though can not be completely free of tester's operation control, it is simple to operate, and is with low cost, more easily promotes.
