Problems solved by technology

[0002] The oil distribution plate is a key part of a hydraulic pump or a hydraulic motor. Its working surface is cast with an inlet and outlet oil window groove, and it is also processed with oil grooves, unloading grooves, round holes, screw holes, etc. These machined oil grooves are different from those casted. There is an accurate angle requirement between the inlet and outlet oil window slots, but the existing oil distribution plate processing technology and fixtures do not meet this requirement, which affects the noise performance of hydraulic pumps or hydraulic motors, and needs to be improved

Abstract

The invention discloses an oil distribution disc pin hole drill jig. The oil distribution disc pin hole drill jig comprises a base and a drill jig plate located above the base; an oil distribution disc is located between the base and the drill jig plate, a spring assembly is arranged on the base, a mandrel is arranged in the center of the base, a working face and a step face are arranged on the oil distribution disc, the working face corresponds to the base in position, and the step face corresponds to the drill jig plate in position; and an open washer and a locking screw are arranged on thedrill jig plate, and the locking screw corresponds to the mandrel in position. By means of the oil distribution disc pin hole drill jig, the technical problem that in existing similar products, the directional included angle between a machining oil groove and a casting oil inlet and outlet window groove is not accurate is solved, the structure is simple, the oil distribution disc can be rapidly clamped, clamping is convenient, then the machining efficiency is greatly improved, and the revenue benefits of enterprises are increased.

Description

technical field [0001] The invention relates to the field of hydraulic oil distribution plates, in particular to a drilling mold for pin holes of an oil distribution plate. Background technique [0002] The oil distribution plate is a key part of a hydraulic pump or a hydraulic motor. Its working surface is cast with an inlet and outlet oil window groove, and it is also processed with oil grooves, unloading grooves, round holes, screw holes, etc. These machined oil grooves are different from those casted. There is an accurate angle requirement between the inlet and outlet oil window slots, but the existing oil distribution plate processing technology and fixtures do not meet this requirement, which affects the noise performance of the hydraulic pump or hydraulic motor and needs to be improved. Contents of the invention [0003] The main purpose of the present invention is to provide an oil distribution plate pin hole drilling mold, which can effectively solve the problems ...
