Testing fixture

The utility model discloses a testing fixture, including base, two at least reference blocks and two at least clamping mechanism, the reference block sets up on the base, clamping mechanism encirclesthe base set up and with the reference block position corresponds, and the work piece setting is in on the reference block, clamping mechanism presss from both sides tight work piece and is in therebypress from both sides on the reference block and tightly be in on the base, simultaneously, it is poor to press from both sides the face that tightly can detect the work piece on the reference blockthrough the multiple spot. Testing fixture will examine the work piece face poor with press from both sides tight process no. 2 and close to one, once press from both sides tight action accomplish simultaneously the inspection face poor with press from both sides tightly, reduced operating time, improved production efficiency. 本实用新型公开了种检具，包括基座、至少两个基准块和至少两个夹紧机构，所述基准块设置在所述基座上，所述夹紧机构环绕所述基座设置并与所述基准块位置对应，工件设置在所述基准块上，所述夹紧机构夹紧工件在所
