Principle of work of the present utility model is:
Shown in Fig. 5 a～5d, lower seal anchor clamps 2 are used to seal the clutch housing oil cylinder inner surface.Go between the lower seal anchor clamps 2 at the clutch housing oil har opening, leave gap (shown in Fig. 5 a) between the external diameter of O-ring seal baffle anchor clamps 23 and the external diameter of second O-ring seal 24 and the housing internal diameter; When measured workpiece was laid, because the existence in gap, clutch housing did not produce friction, not defective work piece (shown in Fig. 5 b) with second O-ring seal 24.After workpiece is put well, axle drives cylinder 21 work, cylinder shrinks, drives sealing axle 22 and moves down, because the top end diameter maximum of sealing axle 22, therefore seal axle 24 and second O-ring seal 24 is compressed make second O-ring seal, 24 cross sections that even variation take place, it is big that the external diameter of second O-ring seal 24 becomes; When distortion was enough big, second O-ring seal 24 evenly was adjacent to clutch housing oil har opening inside surface, plays sealing function (shown in Fig. 5 c).After the measured workpiece test finishes, axle drives cylinder 21 reverse operations, unclamp sealing axle 22, second O-ring seal 24 is under self flexible effect, its cross section shape that resiles, make second O-ring seal, 24 external diameters recover life size, thereby break away from housing oil har opening inside surface, form the gap heavily again between second O-ring seal 24 and the housing internal diameter; When measured workpiece takes out, because measured workpiece does not contact with second O-ring seal 24, do not damage second O-ring seal 24, prolonged the serviceable life (shown in Fig. 5 d) of second O-ring seal 24.
Shown in Fig. 6 a～6c, last sealing clamp 1 is used to test the test sealing of inner cavity surface on the automatic transmission wheel box.External diameter and first O-ring seal, 12 interior external diameters left the gap with clutch housing epicoele sealing surfaces in the last sealing clamp 1 before not being compressed, before last sealing clamp 1 test of insertion housing, because first O-ring seal 12 does not have compression deformation, so inner cavity surface does not contact with first O-ring seal 12 on the clutch coupling; Last sealing clamp 1 clutches epicoele, drive clamping cylinder 13 work, drive by first installing plate 16 and to go up sealing clamp 1 and move down and put in place, first O-ring seal 12 in first O-ring seal 12 on the sealing clamp piece 11 inside surface projectioies 18 and the sealing clamp piece 11 outside surface grooves deforms at the measuring phase lower section that drives clamping cylinder 13, the Internal and external cycle diameter diminishes or strengthens, when distortion was enough big, inside and outside first O-ring seal 12 fully contacted with the clutch coupling upper cavity surface, plays sealing function.When test finishes, drive clamping cylinder 13 and reset, first O-ring seal 12 restores to the original state, and breaks away from the measured workpiece surface; When measured workpiece takes out, because measured workpiece does not contact with first O-ring seal, do not damage first O-ring seal, prolonged the serviceable life of first O-ring seal.
Shown in Fig. 7 a～7c, sealing clamp pedestal 3 is used for the sealing of the clutch outer member face of cylinder and ladder end face.Leave the gap on upper and lower test fixture piece 31,32 and the 3rd O-ring seal 33 and the measured workpiece diametric(al), when measured workpiece in installation process because the existence in gap can not produce friction to the 3rd O-ring seal 33, thereby can not damage the 3rd O-ring seal 33, influence life-span of the 3rd O-ring seal 33.After measured workpiece places, driving clamping cylinder 13 drive measured workpieces inserts in the accommodation space of upper and lower test fixture piece 31,32 formation, because compressing downwards of measured workpiece, make the 3rd O-ring seal 33 cross-wise direction generation homogeneous deformations on the upper and lower test fixture piece 31,32, the 3rd O-ring seal 33 internal diameters are diminished, when distortion was enough big, the 3rd O-ring seal 33 evenly was adjacent to sealing surface, plays sealing function.When the measured workpiece test finishes, drive clamping cylinder 13 and reset, the 3rd O-ring seal 33 restores to the original state, and breaks away from the measured workpiece surface; When measured workpiece takes out, because measured workpiece does not contact with the 3rd O-ring seal 33, do not damage the 3rd O-ring seal 33, prolonged the serviceable life of the 3rd O-ring seal 33.
The utility model is based on the principle of O-ring seal elastic deformation, the drive controlling O-ring seal that utilizes physical construction and cylinder before and after measured workpiece is packed test fixture into distortion and reset to play and neither damage the effect that seal can play sealing function, thereby prolonged the serviceable life of O-ring seal, reduced use cost.
