Abstract
The invention relates to an automatic steel ball measuring riveting press positioning mechanism for a plunger. The positioning mechanism comprises a limiting bottom plate and a guide sleeve which are connected in an abutting mode, the two ends of the guide sleeve are fixedly connected with a positioning block and an end cover, a movable sleeve and a fixed sleeve are connected in an abutting mode and installed inside the guide sleeve, and a sealing cavity for containing a tensioning mechanism is formed at the abutting position of the movable sleeve and the fixed sleeve. The positioning mechanism is simple in structure and convenient to install, the plunger is effectively and accurately positioned through the tensioning mechanism and the positioning block when assembled, and the plunger is assembled firmly and reliably; by means of the movable sleeve and the fixed sleeve, assembly is adjustable, adjustment is reliable and flexible, the stability is achieved when the plunger is machined, and machining efficiency is improved.
Description
Technical field
The present invention relates to mechanical automation equipment, relate in particular to a kind of detent mechanism of automatically measuring riveter for plunger steel ball.
Background technology
Plunger matching parts is formed by plunger and plunger bushing precision-fit, delivery valve matching parts (being made up of delivery valve and delivery valve seat) is equipped with in its top, plunger is to be generally assemblied on the cylinder body of engine, for connecting high-pressure oil pipe and fuel injector, is the passage of fuel oil access to engine combustion chamber.For meet plunger in assembling stability when steel ball, ensure plunger add do not produce man-hour rock, accurate positioning etc., in the urgent need to designing a kind of detent mechanism.
Summary of the invention
The applicant, for above-mentioned existing issue, is studied improvement, a kind of detent mechanism of automatically measuring riveter for plunger steel ball is provided, and has effectively realized accurate positioning, stability that plunger adds man-hour, has improved working (machining) efficiency.
The technical solution adopted in the present invention is as follows:
A kind of detent mechanism of automatically measuring riveter for plunger steel ball, comprise spacing base plate and the guide pin bushing of butt each other, in the affixed locating piece in the two ends of guide pin bushing and end cap, movable sleeve, fixed cover butt being installed in described guide pin bushing each other, is formed for the annular seal space of device tension mechanism in the butt place of described movable sleeve and fixed cover.
Its further technical scheme is:
Described tension mechanism comprises the retainer being arranged symmetrically with, and installs multiple steel balls that are circumference between two retainers;
Described locating piece each other symmetrical and interval arranges, between two locating pieces, along continuous straight runs is formed for the first placed channel of position ram steel ball, is formed for the second placed channel of measuring for gage outfit between vertically;
Formation arc opening caves inward on each locating piece.
Beneficial effect of the present invention is as follows:
The present invention is simple in structure, easy for installation, utilize tension mechanism, locating piece effectively to realize the accurate location to plunger assembling, make plunger assembling solid and reliable, the device of movable sleeve and fixed cover makes assembling have modulability, regulate flexibly reliable, realize the stability that plunger adds man-hour, improved working (machining) efficiency.

Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As Fig. 1, shown in Fig. 2 and Fig. 4, a kind of detent mechanism of automatically measuring riveter for plunger steel ball, comprise spacing base plate 1 and the guide pin bushing 5 of butt each other, as shown in Figure 3, in one end of guide pin bushing 5 by lock-screw 10 and the affixed end cap 7 of stage clip (not marking in figure), the other end in guide pin bushing 5 passes through alignment pin 2 and the affixed locating piece 4 of securing member, locating piece 4 each other symmetrical and interval is arranged, between two locating pieces 4, along continuous straight runs is formed for the first placed channel 401 of position ram steel ball, vertically, be formed for the second placed channel 8 of measuring for gage outfit.On each locating piece 4, also cave inward and be formed for being close to the arc opening 402 of plunger periphery.Movable sleeve 501, fixed cover 502 butt being installed in guide pin bushing 5 each other, is formed for the annular seal space 503 of device tension mechanism at the butt place of movable sleeve 501 and fixed cover 502.As shown in Figure 3, tension mechanism comprises the retainer 11 being arranged symmetrically with, and installs multiple steel balls 6 that are circumference between two retainers 11.The interior perforate all having for running through plunger of above-mentioned movable sleeve 501, fixed cover 502 and end cap 7.
Specific works process of the present invention is as follows:
As shown in Figure 3, Figure 4, first one end of plunger 9 is aimed to the arc opening 402 of each locating piece 4, then successively plunger 9 is run through to fixed cover 502, movable sleeve 501 and end cap 7, plunger 9 is when through steel ball 6, steel ball 6 is stressed to outwards opening, after plunger 9 passes, each steel ball 6 shrinks the application of force to the periphery of plunger 9, has ensured thus the position stability of plunger 9.
More than describing is explanation of the invention, is not the restriction to invention, and limited range of the present invention, referring to claim, within protection scope of the present invention, can be done any type of amendment.
