Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 1, Figure 2 and Figure 3, the strength self-locking hydraulic clamping device of the present embodiment, comprise pedestal 1, the front end face of pedestal 1 is provided with lid 11, one sidewall upper and lower side of pedestal 1 has guiding square hole, be positioned at that pedestal 1 is inner is unsettledly provided with oil cylinder 2, the upper and lower end of oil cylinder 2 is extended with symmetrical piston rod 3 respectively, piston rod 3 head connects front rod 4 and back link 13 by piston rod bearing pin 14, back link 13 other end is connected on pedestal 1 inwall free bearing by free bearing bearing pin 12, and front rod 4 other end is connected with oblique contract slide block 6 by slide block bearing pin 5; Oblique contract slide block 6 is coordinated with oblique contract compact heap 9 by linking springs 10 and is connected, and oblique contract slide block 6 is installed in guiding square hole together with oblique contract compact heap 9; Pedestal 1 has spring mounting hole, and load support spring 7 in spring mounting hole, support slipper 8 is arranged on support spring 7, and support slipper 8 compresses with the end face of oblique contract compact heap 9.During work, oblique contract compact heap 9 and tiltedly contract slide block 6 move along guiding square hole upper surface.
Pedestal 1 one-tenth hollow rectangular structure, on the left of pedestal 1, wall thickness is less than right side wall thickness, and guiding square hole opens the right side in pedestal 1.
The side of oil cylinder 2 is provided with three oilholes, is followed successively by from top to bottom: left oil port joint 17, middle port connection 16 and right oil port joint 15.During clamping, middle hydraulic fluid port oil-feed, left and right hydraulic fluid port oil return, during reset, left and right hydraulic fluid port oil-feed, middle hydraulic fluid port oil return.
As shown in Figure 4 and Figure 5, the slope of oblique contract slide block 6 is arranged protruding 22, one end of oblique contract slide block 6 has pin shaft hole 21; Oblique contract compact heap 9 is provided with groove 20, and protruding 22 embed in grooves 20, and by linking springs 10, oblique contract slide block 6 are realized elasticity with oblique contract compact heap 9 and be connected.Adopt to coordinate and install, allow two oblique contract relative movements.
The large end place of oblique contract compact heap 9 is also provided with boss 19, and the working face of boss 19 abuts with the internal face of pedestal 1.Move for restrictive axial, realize oblique contract compact heap 9 under oblique contract slide block 6 ramp effect, move downward, realize the clamping to workpiece 18.
Two piston rods 3 of the present invention are arranged symmetrically in an oil cylinder 2, and ensure that clamping is synchronous, uniform force, structure simplifies.
In actual use procedure, its course of work is as follows:
