Abstract

The invention discloses a turning clamp of a cast iron oil distribution disc. The turning clamp comprises a positioning seat, a pointed end seat and a pressure block, wherein the positioning seat is arranged on a three-jaw chuck of a main shaft of turning equipment and is used for supporting the large end surface of the cast iron oil distribution disc; the end part of the positioning seat is provided with a positioning assembly, and the positioning assembly corresponds to the position of a flow distribution window of the cast iron oil distribution disc; one end of the pointed end seat is connected with a tailstock of the turning equipment and is matched with the tailstock to carry out positioning and pressing on the cast iron oil distribution disc; and the pressure block is connected with the pointed end seat through a rotary component and is used for pressing the small end surface of the cast iron oil distribution disc. According to the turning clamp, the positioning seat is arranged, the positioning assembly is arranged on the positioning seat, the positioning assembly is used for aligning the flow distribution window of the cast iron oil distribution disc, positioning and clamping of the cast iron oil distribution disc are realized, compared with a clamping mode of a three-jaw clamping outer circle in the prior art, the position precision and the coaxiality precision of the cast iron oil distribution disc are greatly improved.

Description

technical field [0001] The invention relates to the field of turning processing of an oil distribution plate, in particular to a turning fixture for a cast iron oil distribution plate. Background technique [0002] In the field of hydraulic machinery such as existing hydraulic vane pumps, hydraulic vane motors, the use of cast iron oil distribution plates is very extensive. In the hydraulic vane pump or hydraulic vane motor, the oil distribution plate plays the role of separating the high-pressure oil chamber and the high-low oil circuit distribution. When the high-pressure oil acts on the motor, the torque is output, and the low-pressure oil returns to the oil tank; the oil in the oil tank in the pump It is sucked in from the low-pressure chamber and discharged from the high-pressure oil chamber. Such as figure 1 and figure 2 As shown, the cast iron oil distribution plate 100 is designed with a distribution window 101 and an oil groove channel with a complex structure. ...
