Embodiment
Embodiment of the present utility model is described further below in conjunction with the accompanying drawings.
The specific embodiment of workpiece prepackage frock of the present utility model, as shown in Figures 2 to 4, workpiece prepackage frock bag
Include the prepackage seat 7 of platy structure, pre-install and three limited blocks 8 are provided with seat 7, and three of three limited blocks 8 and corresponding workpiece
The practical set benchmark of the U-type groove of arm end is consistent, and limited block 8, which has, is used for the limit that support arm block corresponding with workpiece coordinates
Plane, and the centerline parallel of plane and corresponding support arm where confined planes, and the confined planes of limited block 8 corresponding with the 3rd support arm
Angle between the corresponding confined planes of adjacent limited block 8 is 107 degree.During pre-assembled, by by three of workpiece
The U-type groove 4 of support arm is fastened on the outside of corresponding limited block 8, is engaged guarantor by the face between confined planes and corresponding support arm
Card support arm will not move back and forth under the position-limiting action of limited block 8, when three support arms can be assembled to each self-corresponding limited block 8
When outer, it was demonstrated that two Angular Dimension key elements of the workpiece meet matching requirements.
The adjective-centre structure for the centre bore location fit with workpiece, the adjective-centre structure bag are additionally provided with prepackage seat 7
Include the internal point 10 that setting is extended downwardly along prepackage seat 7 upper surface, and the size of the centre bore of the size of internal point 10 and workpiece
Unanimously, adjective-centre structure also includes being used for the bearing pin 12 being positioned at workpiece by centre bore on internal point, the outer diameter ruler of bearing pin 12
It is very little consistent with the aperture of centre bore.When the position of internal point 10 and the position of three limited blocks 8 are satisfied by the practical set of workpiece
Reference for assembling position.Thus on the premise of angle key element determines to meet matching requirements, workpiece is positioned on prepackage seat 7.
After being finished to angle key element measurement, it is also necessary to the axle of the end mounting hole of two support arms to be measured on workpiece
Whether the distance of line-spacing centre bore unanimously measures, and in the assembling process of reality, workpiece needs satisfaction following apart from key element
Matching requirements：The crosspoint of the axis of mounting hole on two support arms to be measured and the center line of place support arm, respective distance the
The distance of the center line of three support arms is 180mm.
In order to meet the matching requirements, edge offers perpendicular to the direction of mating surface in the mating surface of each limited block 8
Connecting hole 11, the axis satisfaction of the connecting hole 11 is consistent with the axis of the mounting hole of U-type groove in workpiece practical set, that is, treats
The distance of the axis and the center line of the support arm of intersection point distance the 3rd of the center line of measured support arm of the mounting hole surveyed on support arm expires
Sufficient 180mm requirement, and the aperture of connecting hole 11 is consistent with the aperture of mounting hole.Also set on the connecting hole of each limited block 8
It is equipped with the measurement axle for being inserted into after penetrating mounting holes in connecting hole, the radial dimension of the measurement axle and the radial ruler of mounting hole
It is very little consistent.After workpiece is fixed on prepackage seat 7, by entering after measurement axle is penetrated into mounting hole in connecting hole, foundation
Measurement axle can pass through connecting hole to be whether standard judging distance key element meets matching requirements.
When in use, three limited blocks 8 first correspondingly pre-installed the U-type groove on three support arms on workpiece on seat 7 assemble,
If three limited blocks 8 smoothly can enter in U-type groove, show that two Angular Dimension key elements on the workpiece meet assembling
It is required that conversely, then two Angular Dimension key elements are unqualified；After angle key element is qualified, continue in bearing pin penetrating into center hole, so
Three measurement axles are penetrated in the connecting hole of three limited blocks 8 with this afterwards, if three measurement axles can be penetrated smoothly, show this
Two of workpiece meet matching requirements apart from size factor, conversely, then unqualified apart from size factor.
In other embodiments, limited block may be configured as two, and two limited blocks correspond to the 3rd support arm and wherein one respectively
Individual support arm to be measured, it is above-mentioned in the case of symmetrical in workpiece top and bottom because two support arms to be measured are consistent with the angle of the 3rd support arm
Two support arms angle meet require after, it is only necessary to by workpiece turning, you can by two limited blocks to another branch to be measured
Whether the angle between arm and the 3rd support arm meets to require；Limited block may be alternatively provided as the U-type groove for being set in each support arm
Water jacket arm at stopper slot；Limited block can also be set on support arm the stopper slot of correspondence position or along support arm center line pair
Claim two limited blocks for being arranged in support arm both sides, the baffle plate now placed vertically in the opening position setting of support arm mounting hole, baffle plate
On be arranged at the connecting hole of workpiece practical set position consistency, in measurement by measuring whether axle smoothly enters to determine distance
Key element；Adjective-centre structure could be arranged to be fixed on the external diameter pre-installed on the seat centration axis consistent with the aperture of the centre bore of workpiece.
