Description
Technical Field
The utility model belongs to the special fixture field, especially, measure anti pulling force's of taking off special test fixture of cap emblem.
Background
The existing method for measuring the tension is that an upper clamp and a lower clamp are used for clamping a cap emblem main body and a screw respectively, the screw is separated from the main body under the action of a tension machine, the tension is measured by the method, most of conventional clamps are used for clamping plane regular products, no special clamp is arranged on arc-surface products, and the cap emblem main body is of an arc-surface structure, so that the clamping is not tight, the stress is not uniform and the detection accuracy is influenced when the conventional clamps clamp the cap emblem.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome prior art's not enough, provide a measure tensile special test fixture is taken off in cap badge resistance, this special fixture simple structure, design scientific and reasonable, use easy operation.
The utility model provides a technical scheme that its technical problem adopted is:
the utility model provides a measure tensile special test fixture of cap emblem anti-drop, including last holding head, the nut, lower holding head briquetting, lower holding head, fastening screw and lower connecting block are constituteed, it comprises last supporting rod, the fastening block and screw to go up the holding head, upward be threaded on supporting rod and the fastening block, it adorns admittedly to go up the supporting rod with the screw and fastening block, lower connecting block is T style of calligraphy structure, be equipped with through-hole and pin locating hole on, the last recess of lower holding head, the fastening screw, be equipped with connecting hole and screw in the recess, the main shaft of lower connecting block passes the connecting hole of lower holding head and adorns admittedly with lower holding head at the screw department with the screw, the face that lower holding head and lower holding head briquetting contacted with the cap emblem test piece designs into the cambered surface of laminating mutually with the cap emblem main part.
Utility model's advantage and beneficial effect do:
the utility model overcomes present tensile test is with the planar defect of holder centre gripping, changes into the method that lower holding head and lower holding head briquetting cooperation locking come fixed test piece, reaches the fastening centre gripping to satisfy experimental requirement, the utility model discloses simple structure, design scientific and reasonable, use easy operation, it is fine to use the effect at present.
