Embodiment Construction

[0055] Below in conjunction with accompanying drawing and specific embodiment the present invention will be described in further detail:

[0056] A new type of hydraulic corner self-servo compliant driver that is easy to process, including steering gear 1, steering gear disc 2, coupling 3, left end cover 4, fixed stopper 5, valve body boss 6, cylinder body 7, and right end cover 8 , flange 9, valve body shaft 10, valve body 11, blade 12, valve sleeve 13, valve core 14, steering gear seat 15, support 16, cylinder inner ring 17.

[0057] Such as figure 1 and figure 2 As shown, the cylinder inner ring 17 is pressed from the left end of the cylinder body 7 to the internal spigot, and the valve body boss 6 is pressed in from the right end of the cylinder body 7 so that the right end surface is flush with the left end surface of the right bearing groove 27 of the cylinder body, and the valve body The body 11 is concentrically installed in the cylinder inner ring 17 and the valve ...

Abstract

The invention discloses an easily-machined hydraulic corner self-servo compliant driver. According to the hydraulic corner self-servo compliant driver, blades of the driver are fixed on the outer wallof a valve body through screws, a threaded hole is formed in a face, in contact with a cylinder body, of a fixed stop block, mounting through holes, corresponding to the threaded holes, are formed inthe cylinder body, and the fixed stop block is arranged on the inner wall of the cylinder body in a matched mode through screws and the threaded holes; and rectangular grooves are formed in the two rectangular side faces of each blade, each of the two sides of a lower arc face of the blade is provided with an arc groove used for preventing the blade from being tightly stuck to the fixed stop block, and the rectangular grooves communicate with the arc grooves. The cylinder body and the valve body are arranged in a split mode, so that the sealing performance is excellent, the machining and theassembling are facilitated, leakage oil is guided out easily and conveniently, and sticking zones between the blades and the fixed stop block can be prevented; and meanwhile the driver should have thecharacteristics that the valve body and a valve element are stressed evenly and are not probe to shift, the dynamic property is high, the joint flexibility is high, the response speed is high, and the control precision is high.

Description

technical field [0001] The invention belongs to the technical field of hydraulic robot joints, and in particular relates to a novel hydraulic corner self-servo compliant driver which is easy to process. Background technique [0002] The hydraulic corner self-servo compliant drive mechanism is a key part of the hydraulic robot joint technology. Its core is that it combines hydraulic technology with electromechanical technology to form a feedback control system with high power, fast response, and precise response. Its working principle is to use the small torque of the servo motor to drive the valve core to rotate to open the valve port, so that the high-pressure oil acts on the valve body to obtain the output volume that can automatically, quickly and accurately reproduce the change law of the input volume, and at the same time It also performs power amplification on the small torque input by the motor. Therefore, it is widely used in aerospace machinery, robot systems, larg...
