Abstract

A piston compression pin mechanism comprises a compression bar, a floating sleeve, a spring, a punch pin, a guide sleeve, magnets and a pin, wherein the compression bar is arranged inside the floating sleeve through a nut, the spring is connected with the lower end of the compression bar in a sleeved mode, one end of the spring contacts with the compression bar, the other end of the spring contacts with the lower end of the floating sleeve, the punch pin is installed at the lower end of the compression bar, the lower portion of the punch pin extends into the guide sleeve, the pin is installed at the lower end of the compression bar in the guide sleeve, and the magnets are symmetrically arranged on the side face of the lower portion of the floating sleeve. The pin aims at a pin hole in a piston and presses down the compression bar to push the punch pin to press the pin into the pin hole. The piston compression pin mechanism has the advantages of being capable of reaching 100% of rate of finished products, improving work efficiency and reducing cost of consumption and manpower based on technology in the prior art.

Description

Piston pressing in pins mechanism

Technical field

The utility model relates to a kind of Piston Machining equipment, is specifically related to a kind of piston pressing in pins mechanism.

Background technology

At present piston is pressed into the operation of pin, at first will relies on manually pin alignment pins hole, pin is partly knocked in pin hole, then piston is placed on the stamping machine, pin all is pressed into pin hole, such operating process is wasted time and energy, inefficiency.

The utility model content

The purpose of this utility model is the deficiency that exists for prior art, and a kind of quickly and easily piston pressing in pins mechanism is provided.

The purpose of this utility model realizes by following technological means: comprise depression bar, floating bushing, spring, red needle, fairlead, magnet, pin, in floating bushing, be provided with successively depression bar, the red needle that is fixed on the depression bar lower end, fairlead, pin, spring housing is at the lower outside of depression bar, one end in contact depression bar, other end contact floating bushing lower end, fairlead socket red needle bottom and pin top, the floating bushing lower side is provided with magnet.

Preferably, depression bar is installed in the floating bushing by nut.

Preferably, the magnet symmetry is located at the floating bushing lower side.

Compared with prior art the utlity model has following obvious advantage:

1. yield rate can arrive 100%;

2. improved operating efficiency;

3. the loss of cost and artificial expense have been reduced in original technical foundation.

Description of drawings

Fig. 1 is structural representation of the present utility model;

Among the figure, 1-depression bar, 2-nut, 3-floating bushing, 4-spring, 5-red needle, 6-fairlead, 7-magnet, 8-pin, 9-piston.

The specific embodiment

Below in conjunction with description of drawings and the specific embodiment the utility model is described in further detail:

Piston pressing in pins mechanism as shown in Figure 1, comprise depression bar 1, unsteady 3 covers, spring 4, red needle 5, fairlead 6, magnet 7, pin 8, depression bar 1 is located in the floating bushing 3 by nut 2, depression bar 1 lower end socket spring 4, spring 4 one end in contact depression bars 1, other end contact floating bushing 3 lower ends, red needle 5 is installed in the lower end of depression bar 1, the bottom is stretched in the fairlead 6, and pin 8 is installed in the lower end of fairlead 6 inherent depression bars 1, and floating bushing 3 lower side are arranged with magnet 7.

Pin 8 is aimed at the pin hole of piston 9, depresses depression bar 1, promotes red needle 5 pin 8 is pressed in the pin hole.

The above; it only is a part of specific embodiment of the present utility model; protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.
