Problems solved by technology

In order to ensure that the plunger corresponds to the positioning groove of the engine cylinder head, it is necessary to install a positioning protrusion consistent with the number of the positioning grooves on the plunger. The positioning protrusion is generally a steel ball embedded in the plunger. Due to the existing steel ball and The fitting method of the plunger is generally carried out by manual pressing, so the connection firmness between the steel ball and the plunger cannot be guaranteed, and the steel ball is easy to fall out, so it is urgent to design a press-fitting mechanism

Embodiment Construction

[0023] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0024] Such as figure 1 , figure 2 and image 3 As shown, a press-fitting mechanism for plunger steel ball automatic measuring riveting press includes a mounting base 9, which is in a "Z" shape, and a pneumatic lifting unit and a sensing unit are respectively installed on the mounting base 9;

[0025] The specific structure of the pneumatic lifting unit is as follows:

[0026] Including the cylinder 1, the output end of the cylinder 1 runs through the mounting seat 9 and connects to the floating joint 6, the floating joint 6 abuts against the guide plate 7, and the guide plate 7 is located below the floating joint 6, on both sides of the cylinder 1, on the mounting seat 9 A guide post 5 is installed on the top, and a guide sleeve 11 is installed on the outer periphery of the guide post 5 . The end of the guide post 5 is connected to t...

Abstract

The invention relates to a press fitting mechanism for an automatic measurement riveting machine of a plunger steel ball. The press fitting mechanism comprises a mounting base, wherein a pneumatic lifting unit and a sensing unit are arranged on the mounting base. The press fitting mechanism is simple in structure and easy and convenient to operate; due to the arrangement of a photoelectric sensor, the monitoring performance of a plunger is effectively achieved; due to the arrangement of a proximity switch, displacement of a guide pillar is realized; a floating connector is used for eliminating errors, so that the stability during ascending and descending of the output end of an air cylinder is guaranteed, and the service life of equipment is prolonged. By means of all the units of the press fitting mechanism, automatic press fitting of the steel ball in a plunger is realized, time and labor are saved, the previous machining mode that manual pressing is needed is avoided, and machining efficiency is greatly improved.

Description

technical field [0001] The invention relates to mechanical automation equipment, in particular to a press-fitting mechanism for a plunger steel ball automatic measuring riveting press. Background technique [0002] The plunger couple is formed by the precision fit of the plunger and the plunger sleeve, and the oil outlet valve couple (composed of the oil outlet valve and the oil outlet valve seat) is installed above it. The plunger is generally assembled on the cylinder block of the engine. It is used to connect high-pressure fuel pipes and fuel injectors, and is the passage for fuel to the engine combustion chamber. In order to ensure that the plunger corresponds to the positioning groove of the engine cylinder head, it is necessary to install a positioning protrusion consistent with the number of the positioning grooves on the plunger. The positioning protrusion is generally a steel ball embedded in the plunger. Due to the existing steel ball and The fitting method of the...
