Abstract
The invention discloses a mounting base for the vibration test of a high temperature part of an automobile engine, wherein a base body is a cuboid, and is characterized in that: the upper surface of the base body is the mounting surface of a sensor; a longitudinal boss is arranged at the middle part of the lower surface of the base body, and external threads are arranged on the lower boss, and are used for installing the high temperature part of the automobile engine; lateral bosses of the same shape are respectively arranged at the middle parts of the left side and the right side of the base body, and are respectively provided with external threads for installing ferrule type pipe ports; the ferrule type pipe ports are standard parts; and a through hole which penetrates through the two lateral bosses is arranged in the base body along the length direction, and is a cooling water passing channel. The invention has the beneficial effects that: the mounting base is adopted for the vibration test of the high temperature part of the automobile engine, so the vibration sensor cannot be damaged due to the high temperature; and special apparattuses for the vibration test of the high temperature parts are not needed to be additionally purchased, so the mounting base is low in cost, is simple to manufacture, is quick to install and can also be repeatedly used.
Description
Technical field
The present invention relates to a kind of mounting base that can in motor car engine NVH bench test, be used for the high-temperature component vibration-testing.
Background technology
When carrying out engine NVH bench test; High-temperature component (like the exhaust gear of engine) temperature is very high; Can not directly paste sensor in exhaust manifold or heat shield surface measures; And test need be measured the vibration of high-temperature component, can only use contactless survey instrument (like laser vibration measurer) to test its vibration situation.Such way need be purchased new testing apparatus, and is with high costs, and vibrates excessive the time when high-temperature component, and test findings is insincere.
Summary of the invention
The purpose of this invention is to provide a kind of mounting base that is used for motor car engine high-temperature component vibration-testing; It can be used for motor car engine NVH bench test; Utilize existing vibration transducer that the motor car engine high-temperature component is carried out vibration-testing; Test result accurately and reliably, and is easy to use, with low cost.
For solving the problems of the technologies described above, technical scheme of the present invention is following:
A kind of mounting base that is used for motor car engine high-temperature component vibration-testing, base body is rectangular parallelepiped, it is characterized in that:
The top of said base body is the sensor installed surface; There is a vertical boss at the following middle part of said base body, and this lower convex platform is provided with external thread, is used to install the motor car engine high-temperature component; The middle part, two sides, the left and right sides of said base body is respectively equipped with a shape same lateral boss, and two horizontal boss are equipped with external thread, are used to install the bite type tube interface; Described bite type tube interface is a standard component; Be provided with the through hole of two horizontal boss of a perforation in the said base body along its length, this through hole is that cooling water flow is through passage.
Further, said vertical boss and two horizontal boss and base body are an integral body.
Beneficial effect of the present invention: adopt the present invention that the motor car engine high-temperature component is carried out vibration-testing; Only need nut of welding on the motor car engine high-temperature component; There is vertical boss to be connected with the following middle part of base body; And chilled water is flow through from the through hole in the base body, and can directly utilize ready-made vibration transducer to carry out vibration-testing, can not cause vibration transducer to damage by Yin Gaowen; Do not need buying in addition to be specifically designed to the instrument of high-temperature component vibration-testing, with low cost, manufacturing is simple, installs rapidly, can also reuse.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the synoptic diagram that the present invention is connected with the motor car engine high-temperature component.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is done further explain:
Referring to a kind of mounting base that is used for motor car engine high-temperature component vibration-testing shown in Figure 1, base body is rectangular parallelepiped; Top 2 of said base body is the sensor installed surface; There is vertical boss 4 at the following middle part of said base body, and this lower convex platform is provided with external thread, is used to install the motor car engine high-temperature component; The middle part, two sides, the left and right sides of said base body is respectively equipped with 1, two horizontal boss of a shape same lateral boss and is equipped with external thread, is respectively applied for bite type tube interface 6 is installed; Be provided with the through hole 3 of two horizontal boss of a perforation in the said base body along its length, this through hole is that cooling water flow is through passage.
Need nut that matees with vertical boss 4 of welding on the test position at the motor car engine high-temperature component, make it to be connected with this installation pedestal; Two plastic tubes 5 are connected with two bite type tube interfaces 6 respectively; Two bite type tube interfaces 6 are connected with two horizontal boss 1 respectively, and the painting water-proof adhesive sealing; After connection finished, 2 pasted vibration transducers on base body, connected recirculated cooling waters through plastic tube 5, can carry out the vibration-testing of high-temperature component.
In motor car engine NVH bench test, through external recirculated cooling water, cooling water flow is through chilled water through hole 3, makes top 2 temperature of base body be reduced to sensor and allows in the operating temperature range, thereby carry out the vibration-testing of high-temperature component.
Claims (2)
1. mounting base that is used for motor car engine high-temperature component vibration-testing, base body is rectangular parallelepiped, it is characterized in that: top (2) of said base body are the sensor installed surface; There is a vertical boss (4) at the following middle part of said base body, and this lower convex platform is provided with external thread; The middle part, two sides, the left and right sides of said base body is respectively equipped with a shape same lateral boss (1), and two horizontal boss are equipped with external thread, are used to install bite type tube interface (6); Be provided with the through hole (3) of two horizontal boss of a perforation in the said base body along its length, this through hole is that cooling water flow is through passage.
