Feeding device convenient to use for plunger sleeve fixing device of plunger sleeve mill

Abstract

The invention discloses a feeding device convenient to use for a plunger sleeve fixing device of a plunger sleeve mill. The feeding device comprises a base, a sliding rod body, a sliding seat, a threaded rod, a lifting seat, a material placing plate, a groove-shaped material blocking body, a feeding mechanism, a pushing mechanism, a mounting base body, a driving stepping motor, a discharging hole,a discharging plate, a shaft body, a tension spring and a baffle body; the base is provided with the sliding rod body, the rotatable threaded rod and the groove-shaped material blocking body, whereinthe groove-shaped material blocking body is located between the sliding rod body and the threaded rod; and the sliding seat which is installed in a sliding mode is arranged on the sliding rod body, the threaded connection lifting seat sleeves the threaded rod, the material placing plate which is positioned in the groove-shaped material blocking body is arranged between the sliding seat and the lifting seat, and one end of the mounting base body is fixedly connected to the upper end of the sliding rod body. According to the feeding device convenient to use for the plunger sleeve fixing deviceof the plunger sleeve mill, compared with the prior art, the use is convenient, the working efficiency is improved, and the structure is simple.

Description

【Technical field】 [0001] The invention relates to the technical field of a plunger sleeve end surface grinding machine, in particular to the technical field of an easy-to-use feeding device for a plunger sleeve fixing device of a plunger sleeve grinder. 【Background technique】 [0002] In the industry of producing oil pump nozzle plunger sleeve, it is a typical labor-intensive enterprise with multiple processes, which has the characteristics of high technical requirements, complex processing technology, low production efficiency and high production cost. At present, the vast majority of domestic manufacturers still adopt the original processing technology. Generally, the two main processes of turning the plunger sleeve shape and drilling the sleeve hole are used to produce the plunger. Among them, the turning plunger sleeve appearance is in a The standard bar of fixed length is sawed by sawing machine, and the outer circle of different diameters is cut in sections on the same...

[0002] In the industry of producing oil pump nozzle plunger sleeve, it is a typical labor-intensive enterprise with multiple processes, which has the characteristics of high technical requirements, complex processing technology, low production efficiency and high production cost. At present, the vast majority of domestic manufacturers still adopt the original processing technology. Generally, the two main processes of turning the plunger sleeve shape and drilling the sleeve hole are used to produce the plunger. Among them, the turning plunger sleeve appearance is in a The standard bar of fixed length is sawed by sawing machine, and the outer circle of different diameters is cut in sections on the same plunger sleeve blank by a small lathe to meet the process requirements, and the end of the bar sawed by the sawing machine is Both need to be ground by a grinding machine. In the prior art, ordinary fixing devices are generally used to fix the plunger sleeve blank, which has low working efficiency and is inconvenient to use.
