The lower end surface of described concave spherical surface pad forms concave spherical surface, and in the lower end of concave spherical surface pad, and the inboard that is positioned at adpting flange also is provided with the protruding ball ring that the lower end surface of upper-end surface and concave spherical surface pad matches.
The inboard of described adpting flange forms down L shaped inner peripheral surface, and the outside of described concave spherical surface pad forms step-like outer circumferential face, and adpting flange hangs on the stepped shaft outer circumferential face of concave spherical surface pad and combines with the concave spherical surface pad by it being fallen L shaped inner peripheral surface.
Combining between described adpting flange and the concave spherical surface pad is formed with 0.2～0.7 gap.
The outer periphery of described cylinder body lower end is provided with stud and the fastening block that is used for fixing on top beam of hydraulic machine.
Also be provided with primary seal between the inner peripheral surface of described cylinder body and the outer circumferential face of plunger rod.
Also be provided with between the inner peripheral surface of described cylinder body and the outer circumferential face of plunger rod and be convenient to the upper and lower mobile guidance tape of plunger rod.
Also be provided with cylinder mouth clamp, described cylinder mouth clamp is by bolt and be formed on the screw that the cylinder body bottom has, and cylinder body and plunger rod are combined securely.
Advantage and good effect that the present invention has are: because anti partial loading oil cylinder in use for large size hydraulic machine of the present invention adopts above-mentioned structure, make hydraulic press simple in structure, compactness, cylinder body good sealing effect.The plunger rod of hollow is saved material and has been reduced whole cost, has also reduced the consumption of power simultaneously.The cooperation of a pair of ball ring that matches by convex-concave has reached the purpose of anti-bias load.
