Abstract

The invention belongs to the technical field of precision grinding technologies and particularly relates to a grinding tool and method for a square hole of a servo mechanism roller transmission piston rod. The tool comprises a base, a support assembly fixed on the base, a fixed block fixed on the side surface of the support assembly and located at the upper part of the base, a sliding block fixed on the side surface of the fixed block and located at the upper part of the base, a vertical rod fixed at the upper part of the support assembly, a press plate fixed on the vertical rod and capable of moving up and down, a spring with one end fixed at the lower end of a middle hole of the press plate as well as a spring fixing seat fixed at the other end of the spring; and opposite V-shaped grooves are formed in the fixed block and the sliding block. With the precision grinding technology for the square hole of the servo mechanism roller transmission piston rod, the edge collapsing phenomenon is eliminated, the first-time yield is substantially increased to be 95% or higher, machining procedures are reduced, the workload of surface treatment and grinding procedures is also reduced, and the production quality and efficiency are substantially improved.

Description

technical field [0001] The invention belongs to the technical field of precision grinding technology, and in particular relates to a grinding tool and a grinding method for a square hole of a servo mechanism roller drive piston rod. Background technique [0002] The square hole piston rod is an important functional part in the XX-3A and XX-2F secondary servo mechanisms. The reciprocating motion of the piston rod is realized by the pressure change of the actuator at both ends, and the swing of the traveling engine is realized through the transmission mechanism parts such as the shaft sleeve, the pin shaft, and the crank. The two parallel surfaces of the square hole of the piston rod (hereinafter referred to as "square hole") and the shaft sleeve are in linear contact and rolling friction, the fit clearance is 8-15μm, and the maximum bearing pressure is about 10kN. At the same time, the outer circle and the actuator have dynamic sealing requirements, so the dimensional accura...
