Power size.
In view of the very high degree of precision requirement of the utility model use environment, the utility model is made of integrated molding mode
Synchronous clamping jaw 3：First, shaping is processed to a block of metal by CNN；Secondly, the block of metal of machine-shaping is carried out
It cuts again, forms six clamping jaws.Such processing method to be consistent in the short transverse of clamping jaw, effectively reduces and adds
Error in the short transverse of the synchronous clamping jaw 3 brought during work improves the flatness of synchronous clamping jaw 3, so as to reduce the production of spring class
When product 6 are tested, the error in system that synchronous clamping jaw 3 is brought.
2nd, the achievable synchronous clamping jaw 3 of the utility model can realize the firm crawl of spring class product 6 to be detected, avoid fixture
In test mode bottom offset and deformation, the systematic error tested is caused：
Fixture not only needs compatible each model on the premise of accurately synchronizing moving is realized in the test of spring class product 6
Product, and test equipment apply about 30 tons of heavy strength ensure that fixture does not have displacement and change when on product and fixture
Shape.
First, common clamping jaw is smaller mainly for the crawl axially loaded of light matter body, and the power source used uses more
The consistent requirement of clamping jaw crawl precision can not pneumatically be met.Secondly, common clamping jaw inner gear structure due to its architectural characteristic by
To strength it is excessive when it is fragile, even if using the material of intensity bigger, since gear structure is stressed directly in extremely difficult guarantee gear
Under the background of the installation accuracies such as gap requirement, it is likely that according into clamping jaw Influence of Displacement during test to test result.
The utility model changes previous pneumatic mode using servomotor 4 as power source, ensures that synchronization during crawl adds
Clamping jaw can provide huge axial force, enhance the stability of synchronous clamping jaw 3, ensure test equipment apply more times of gravity in
When on product and fixture, fixture does not generate displacement and deformation.
3rd, the utility model be compatible with miscellaneous spring class product 6 to be detected, it can be achieved that spring class product 6 to be detected it is quick
It picks and places, improves detection efficiency：
The utility model can realize the quick fetching of spring class product to be detected by the way of the transmission of conveyor chain 22, pass through
Manipulate servomotor 4, can a step realize the quickly opening and closing of synchronous clamping jaw 3, collapse, improve spring class product to be detected and be put into, take out
The efficiency of fixture.
In conclusion the utility model provides a kind of spring class product test fixture, it can be achieved that high-precision by the utility model
Degree, firm, synchronous promptly spring class product to be detected, avoid fixture in test mode bottom offset and deformation, the system for causing test
Error；The utility model is compatible with miscellaneous spring class product to be detected, realizes the quick fetching of spring class product to be detected, improves
Detection efficiency.
The above is only the preferred embodiments of the present utility model only, is not intended to limit the utility model, all in this practicality
All any modification, equivalent and improvement made within new spirit and principle etc., should be included in the guarantor of the utility model
Within the scope of shield.
