Abstract
The utility model relates to field of mechanical technique, the procapsid vacuum fixture of specifically a kind of improvement, comprise chuck body, the central authorities of chuck body are provided with boss, the surface of chuck body is provided with through hole one, through hole one is looped around around boss, the central authorities of boss are provided with bulge-structure, the surface of boss is provided with through hole two, through hole two is looped around around bulge-structure, procapsid is set in chuck body, and the mesopore inner cervical bottom of procapsid is buckled on bulge-structure, and mesopore inner cervical bottom and bulge-structure are tightly connected.The utility model compared with the existing technology, devise procapsid vacuum fixture structure, sealing place is changed into the mesopore inner cervical bottom of procapsid, eliminate the sealing cover structure outside mesopore, in vacuum test process, not only can Exhaust Gas rapidly, make procapsid inside produce vacuum, to judge whether gas leakage, and can judge whether procapsid inner cervical has cracking, avoid erroneous judgement, improve the qualification rate of part.
Description
Technical field
The utility model relates to field of mechanical technique, the procapsid vacuum fixture of specifically a kind of improvement.
Background technology
One vapour A platform part occurs that inner cervical ftractures, and affects performance.See Fig. 1, former vacuum test fixture be use seal cover to seal procapsid mesopore outside after 1, discharge internal gas, make to produce vacuum in housing.But because inner cervical crack location 3 is positioned at seal cover rubber stopper bottom, former vacuum test fixture cannot detect the situation that inner cervical ftractures, and can be mistaken for pieces O.K..
Therefore, need to design a kind of procapsid vacuum fixture that can detect the improvement that inner cervical ftractures.
Summary of the invention
The purpose of this utility model overcomes the deficiencies in the prior art, provides a kind of procapsid vacuum fixture that can detect the improvement that inner cervical ftractures.
In order to achieve the above object, the utility model devises a kind of procapsid vacuum fixture of improvement, comprise chuck body, it is characterized in that: the central authorities of chuck body are provided with boss, the surface of chuck body is provided with through hole one, through hole one is looped around around boss, the central authorities of boss are provided with bulge-structure, the surface of boss is provided with through hole two, through hole two is looped around around bulge-structure, procapsid is set in chuck body, and the mesopore inner cervical bottom of procapsid is buckled on bulge-structure, and mesopore inner cervical bottom and bulge-structure are tightly connected.
Described through hole one annular distribution is on the surface of chuck body.
Described through hole two annular distribution is on the surface of boss.
The diameter of described chuck body mates with the inside diameter of procapsid.
The utility model compared with the existing technology, devise procapsid vacuum fixture structure, sealing place is changed into the mesopore inner cervical bottom of procapsid, eliminate the sealing cover structure outside mesopore, in vacuum test process, not only can Exhaust Gas rapidly, make procapsid inside produce vacuum, to judge whether gas leakage, and can judge whether procapsid inner cervical has cracking, avoid erroneous judgement, improve the qualification rate of part.
Accompanying drawing explanation
Fig. 1 is the procapsid structural representation of a vapour A platform.
Fig. 2 is structural representation of the present utility model.
Fig. 3 is use schematic diagram of the present utility model.
See Fig. 1-Fig. 2,1 is outside mesopore; 2 is mesopore inner cervical bottom; 3 is inner cervical crack location; 4 is chuck body; 5 is boss; 6 is through hole one; 7 is through hole two; 8 is bulge-structure.
Detailed description of the invention
Now by reference to the accompanying drawings the utility model is described further.
See Fig. 2, the utility model devises a kind of procapsid vacuum fixture of improvement, comprises chuck body.The central authorities of chuck body 4 are provided with boss 5, the surface of chuck body 4 is provided with through hole 1, through hole 1 is looped around boss 5 around, the central authorities of boss 5 are provided with bulge-structure 8, the surface of boss 5 is provided with through hole 27, and through hole 27 is looped around bulge-structure 8 around, and procapsid is set in chuck body 4, the mesopore inner cervical bottom 2 of procapsid is buckled on bulge-structure 8, and mesopore inner cervical bottom 2 and bulge-structure 8 are tightly connected.
In the utility model, through hole 1 annular distribution is on the surface of chuck body 4.
Through hole 27 annular distribution is on the surface of boss 5.
The diameter of chuck body 4 mates with the inside diameter of procapsid.
See Fig. 3, procapsid operationally, is set in chuck body 4 by the utility model, and mesopore inner cervical bottom 2 and bulge-structure 8 seal, and after being discharged by internal gas, carries out vacuum test by through hole 1 and through hole 27.If inner cervical crack location 3 ruptures, then procapsid inside cannot realize vacuum, so just can judge whether procapsid inner cervical situation about ftractureing occurs easily.
The utility model devises procapsid vacuum fixture structure, sealing place is changed into the mesopore inner cervical bottom 2 of procapsid, eliminate the sealing cover structure of outside mesopore 1, in vacuum test process, not only can Exhaust Gas rapidly, make procapsid inside produce vacuum, to judge whether gas leakage, and can judge whether procapsid inner cervical has cracking, avoid erroneous judgement, improve the qualification rate of part.
