Specific embodiment
Specific embodiment in reference to the accompanying drawing is described further the utility model.
Refering to shown in Fig. 3-8, a kind of positioning device of piston press mounting tool welding of the utility model is applied to piston pressure
To the welding of spring pocket 3 and connector 4 in holding tool, which includes guide sleeve 1 and two fixing sleeves 2, wherein guide sleeve 1
It is hollow structure with fixing sleeve 2, two fixing sleeves 2 are respectively sleeved at the both ends of guide sleeve 1, in guide sleeve 1 and fixing sleeve 2
Between be equipped with cylindrical cavity 6 for the spring pocket 3 that twists, before welding, Rectangular Spring steel plate is rolled into cylindrical tube and forms bullet
Spring set 3, the both ends of spring pocket 3 are socketed in two about 2 fixing sleeves, then guide sleeve 1 is inserted into the inner cavity of spring pocket 3,
It falls into spring pocket 3 in cylindrical cavity 6, twists setting to spring pocket 3, guide angle 10 is equipped in 2 one end of fixing sleeve, convenient for guiding
The insertion of set 1 is equipped with the limit shoulder 7 that limited spring covers 3 axial displacements on the fixing sleeve 2 of 6 bottom of cylindrical cavity, prevents
