Abstract

The invention relates to a fast mounted fixture for a plunger sleeve. The fast mounted fixture comprises a sliding sleeve, a joint sleeve coaxially arranged in the sliding sleeve, a lining coaxially arranged in the joint sleeve, and a telescopic spring and a locating pin which are further arranged on the joint sleeve in the sliding sleeve, wherein the end part of the joint sleeve extends into the sliding sleeve and is in thread connection with the joint sleeve, and the telescopic spring is propped against with the locating pin. The fast mounted fixture disclosed by the invention is simple in structure and convenient to use, the joint sleeve is relatively in sliding connection with the sliding sleeve, and meanwhile, an inclined plane is opened in the sliding sleeve, and the plunger sleeve is fixed and separated in the lining effectively by using the locating pin and the telescopic spring to greatly improve the clamping efficiency of the plunger sleeve and enhance the work efficiency.

Description

A kind of fast fixture for plunger bushing
Technical field
The present invention relates to frock clamp, relate in particular to a kind of fast fixture for plunger bushing.
Background technology
Plunger matching parts is formed by plunger and plunger bushing precision-fit, and delivery valve matching parts (being made up of delivery valve and delivery valve seat) is equipped with in its top.In prior art, for plunger bushing is processed, normally by plunger bushing device in conventional brace, again the plunger bushing machining is unloaded when processing clamper for disassembling after, this kind of processing mode processes at every turn and all needs to unload fixture one time, wastes time and energy, and greatly affected working (machining) efficiency.
Summary of the invention
The applicant, for above-mentioned existing issue, is studied improvement, and a kind of fast fixture for plunger bushing is provided, and has effectively realized the rapid-assembling/disassembling of plunger bushing, has greatly improved working (machining) efficiency.
The technical solution adopted in the present invention is as follows:
A kind of fast fixture for plunger bushing, comprise sliding sleeve, be positioned at described sliding sleeve coaxial device female connector, the end of joint is stretched in described sliding sleeve and is threaded in described female connector, be positioned at described female connector coaxial device lining, be positioned at described sliding sleeve, returning apparatus coil tension spring and alignment pin in described female connector, coil tension spring and alignment pin butt each other.
Its further technical scheme is:
Between sliding sleeve and female connector, returning apparatus back-up ring in described sliding sleeve;
Inner face at described sliding sleeve also has inclined-plane;
Be positioned at symmetry on described lining and have installing hole.
Beneficial effect of the present invention is as follows:
The present invention is simple in structure, easy to use, by by be slidably connected relative with sliding sleeve of female connector, in sliding sleeve, have inclined-plane simultaneously, utilize alignment pin and coil tension spring effectively to realize the fixing and disengaging of plunger bushing in lining, the clamping efficiency that has greatly improved plunger bushing, has improved operating efficiency.
Accompanying drawing explanation
Fig. 1 is front view of the present invention.
Fig. 2 is the sectional structure schematic diagram of Fig. 1 in P-P direction.
Fig. 3 is the structural representation after apparatus of the present invention plunger bushing.
Wherein: 1, joint; 2, back-up ring; 3, female connector; 301, spring mounting hole; 4, sliding sleeve; 401, inclined-plane; 5, lining; 501, installing hole; 6, alignment pin; 7, coil tension spring; 8, plunger bushing; 801, oilhole.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 1 and Figure 2, a kind of fast fixture for plunger bushing, comprise sliding sleeve 4, be positioned at sliding sleeve 4 coaxial device female connectors 3, the end of joint 1 is stretched in sliding sleeve 4 and is threaded in female connector 3, is positioned at female connector 3 coaxial device linings 5, is positioned at sliding sleeve 4, returning apparatus coil tension spring 7 and alignment pin 6 in female connector 3, coil tension spring 7 and alignment pin 6 butt each other.Between sliding sleeve 4 and female connector 3, at the interior returning apparatus back-up ring 2 of sliding sleeve 4,2 position-limiting actions of back-up ring.Inner face at sliding sleeve 4 also has inclined-plane 401.Above-mentioned sliding sleeve 4, female connector 3 and lining 5 are hollow cylindrical shell, and on described lining 5, also symmetry has installing hole 501.
Specific works process of the present invention is as follows:
As Fig. 1, shown in Fig. 3, first by piecing devices machine chuck, due to sliding sleeve 4 with female connector 3 for being slidably connected, relative sliding sleeve 4 and female connector 3 are moved upward, because the inclined-plane 401 of sliding sleeve 4 rises, alignment pin 6 is no longer contacted with the internal face of sliding sleeve 4, alignment pin 6 backward the inside contracting that do not carry the baby, then plunger bushing 8 is packed in lining 5, sliding sleeve 4 is being moved downward, now alignment pin 6 is stressed and contact and stretch out with the inwall of sliding sleeve 4, its extension passes the installing hole 501 of lining 5 and connects with the oilhole of plunger bushing 8, guarantee the fixing of plunger bushing 8, thereby can process plunger bushing 8.
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 modification.
