Description
Technical field
This utility model belongs to testing techniques of equipment field, and in particular to a kind of air tightness detection apparatus.
Background technology
Cylinder head is a very important part in engine system, and which directly influences the performance of electromotor（Output
Moment of torsion and power）.When electromotor in it is high-power when, need more fuel oils that burn, be also accomplished by certainly more air,
In addition, when belt speed is stable, need again to adjust air capacity to ensure the burning of a small amount of fuel oil, will so as to meet fuel economy
Ask, these are all that the structure of this system is very complicated by adjusting the air inflow of gas handling system realizing.For obtaining finished product
Cylinder cap, when cylinder cap mechanical processing process is detected, performance air-leakage test be in the course of processing it is very important together
Operation.Traditional detection meanss are range estimations, as engine cylinder cover structure is compact, collect air flue（Air intake duct and exhaust duct）, water channel
（Cooling water circulation passage）And oil duct（Combustor oil supply system）In one, and using the method for range estimation often due to answering for air flue
It is miscellaneous, hidden（Such as the casting sand hole inside cylinder cap）Missing inspection is caused etc. factor so that the effect on driving birds is not good of detection, cause the matter of product
Amount is greatly affected.
At present, although also have and cylinder cap is immersed in the water into the air-tightness to cylinder cap using air tightness detection equipment detects,
Although this method can solve the problem that the problem of missing inspection, in detection process, on the one hand as cylinder cap is not obtained reliably
Fixed, cylinder cap is moved in detection process, affects Detection results；On the other hand, as the size variation of workpiece is than larger,
Prevent testing equipment causes work efficiency to reduce from being adapted to the air-leakage test of various workpiece.
Utility model content
This utility model purpose is to provide a kind of air tightness detection apparatus suitable for different workpieces.
Based on object above, this utility model takes technical scheme below：
A kind of air tightness detection apparatus, including support, are provided with crossbeam at the top of support, slidably connect on the crossbeam to
Few three lower air cylinders, are provided with downward telescopic shaft, are also associated with least two suspension rods, hang on crossbeam in each lower air cylinder
Bar lower end is connected with supporting plate, is provided with rolling mechanism on the supporting plate, is provided with workbench, on the workbench on rolling mechanism
Left sealing plate and right sealing plate is provided with, propulsion cylinder on right sealing plate, is connected with, propulsion cylinder is provided with telescopic compression
Block, the support bottom are connected with water tank by lift cylinder, and the water tank is located at below workbench.
The crossbeam has two, in cruciform shape, offers fixing groove on crossbeam, is connected with first at the top of lower air cylinder
Bolt, the first bolt wear fixing groove, and the free end of the first bolt is fixed by nut.
The workbench is provided with chute of the section in inverted T-shaped, is provided with the second bolt, left sealing plate and the right side in the chute
Sealing plate is bolted on workbench by second.
The rolling mechanism is roller.
Compared with prior art, this utility model has the advantages that：
It is this utility model small volume, lightweight, easy to operate, only cylinder need to be positioned on the inside of left sealing plate during detection,
Then lower air cylinder and compact heap distinguish compression cylinder, you can carry out air-leakage test, and detection time is short, accuracy of detection is high, peace
Overall coefficient is high, long service life, and lower air cylinder can be different according to the size of cylinder, shape in the fixing groove of crossbeam, enter
Move around row, it is easy to loading and unloading, be easy to the correct position compression cylinder in cylinder head, left sealing plate and right sealing plate
It is also moveable on workbench, when mobile, only need to unclamps fixing nut, can be by left sealing plate and right sealing plate according to cylinder head
The size of workpiece is moved, to adapt to workpiece with different size and shape.
