The detection fixture of auto sunroof abat vent bracket
Technical field
The present invention relates to auto parts and components pick-up unit field, be specially the detection fixture of auto sunroof abat vent bracket.
Background technology
A kind of auto sunroof abat vent bracket, it comprises the sunshade cord support bar at horizontal support and horizontal support two ends, horizontal support is connected by sunshade cord with two ends sunshade cord support bar, for this kind of auto sunroof abat vent bracket, need to carry out under use state the horizontal range between horizontal support two ends mounting hole and datum hole and the flexibility of horizontal support, because horizontal support and two ends sunshade cord support bar are flexible material, make, thereby it is directly positioned over to detection platform cannot detects exactly.
Summary of the invention
For the problems referred to above, the invention provides the detection fixture of auto sunroof abat vent bracket, it can use state by effective simulated automotive skylight abat vent support when detecting, and guarantees the accuracy of testing result.
Its technical scheme is such, it comprises base plate, it is characterized in that: origin reference location piece and simulation positioning compression device are installed on described base plate, described origin reference location piece is provided with two, is installed on respectively the transverse ends portion of described base plate, and described simulation positioning compression device is provided with two groups, symmetry is installed on described two horizontal inner sides of origin reference location piece respectively.
It is further characterized in that: described simulation positioning compression device comprises simulated block and folder energetically, and described folder is energetically installed on holder energetically, and described simulated block and described holder are energetically fixed on described backplate surface, and the described pressure head pressing from both sides is energetically over against described simulated block; Described two origin reference location piece surfaces all have sunshade cord support bar locating slot, in described sunshade cord support bar locating slot, are provided with origin reference location projection, on described two reference blocks, sunshade cord support bar locating slot is laterally provided with register pin in inner side; Longitudinal upside of described two origin reference location pieces is provided with longitudinal push rod by push rod bearing, and described longitudinal push rod is over against the sunshade cord support bar locating slot on described reference block.
The detection fixture that adopts auto sunroof abat vent bracket of the present invention, its beneficial effect is: it is by the use state of simulation positioning compression device simulate for lateral support, thus the accuracy that assurance detects.
