Description

Plunger piston borehole positioning apparatus
Technical field:
The present invention relates to a kind of plunger piston borehole positioning apparatus.
Background technology:
A kind of plunger is arranged in the prior art, and as shown in Figure 1, an end of this plunger is provided with two laterally zygomorphic planes 1, is connected with between two planes 1 and two planes, 1 mutually perpendicular through hole 2.At present, in mechanical processing process, for positional precision and the surface roughness that guarantees above-mentioned through hole 2, the workman has generally adopted the bore hole operation one, promptly above-mentioned through hole 2 is carried out heavy boring or right boring, so that through hole 2 can reach desired machining accuracy.But in the process of bore hole, the perpendicularity on the axis of through hole 2 and two planes 1 but can't reach accuracy preferably on the plunger, thereby influences the later duty of plunger.
Summary of the invention:
The technical problem to be solved in the present invention is, provides a kind of axis that can guarantee processed plunger piston borehole and bore hole end face and bottom surface to reach the plunger piston borehole positioning apparatus of accurate perpendicularity.
Technical solution of the present invention is that a kind of plunger piston borehole positioning apparatus with following structure is provided: it comprises angle locating piece, base plate and the perpendicularity locating piece that is connected with base plate; Described angle locating piece is provided with a through hole that can allow plunger rod pass; Described angle locating piece left end is connected with a dog screw I that plunger can be fixed in the through hole; Described angle locating piece right-hand member bottom is connected with supporting screw II; Described supporting screw II and base plate removably connect; Described perpendicularity locating piece relative angle is provided with a shrinkage pool that is used for placing the plunger piston borehole end to locating piece one side; Described shrinkage pool bottom surface and end face are horizontal plane; Be provided with a cushion block in the described shrinkage pool; The bottom surface of described cushion block is parallel with end face with the shrinkage pool bottom surface; Described perpendicularity locating piece top is provided with the screwed hole that communicates with shrinkage pool; Be connected with screw III on the described screwed hole; Described screw III bottom is connected with cushion block.
After adopting above structure, compared with prior art, the present invention has the following advantages: put into the present invention's shrinkage pool when the plunger piston borehole end after, the workman can be fixed on the plunger piston borehole end in the shrinkage pool by screw III and cushion block, and plunger is fixedlyed connected with the angle locating piece with dog screw I, because described supporting screw II and base plate removably connect, therefore, after the workman unclamps screw III and takes out plunger, the workman can move to plunger and angle locating piece and supporting screw II together on the anchor clamps of lathe and position bore hole, because shrinkage pool bottom surface and end face are horizontal plane described in the present invention, and the bottom surface of described cushion block is parallel with end face with the shrinkage pool bottom surface, in moving process, plunger is relative all the time static with angle locating piece and supporting screw II, therefore, the axis of processed plunger its bore hole in the bore hole process and bore hole end face and bottom surface can reach accurate perpendicularity.Description of drawings:
Fig. 1 is the perspective view of processed plunger.
Fig. 2 is the structural representation of plunger piston borehole positioning apparatus of the present invention.
Fig. 3 is the structural representation when on Fig. 2 plunger being installed.
Fig. 4 is the structural representation when being clamped on the anchor clamps of the present invention when plunger is installed.
Shown in the figure: 1, plane, 2, through hole, 3, base plate, 4, dog screw I, 5, cushion block, 6, screwed hole, 7, screw III, 8, the perpendicularity locating piece, 9, plunger, 10, through hole, 11, screw II, 12, the angle locating piece, 13, shrinkage pool.
Specific embodiment:
The invention will be further described below in conjunction with the drawings and specific embodiments:
As shown in Figures 2 and 3, in this specific embodiment, plunger piston borehole positioning apparatus of the present invention comprises angle locating piece 12, base plate 3 and the perpendicularity locating piece 8 that is connected with base plate 3; Described angle locating piece 12 is provided with a through hole 10 that can allow plunger rod pass; Described angle locating piece 12 left ends are connected with a dog screw I4 that plunger 9 can be fixed in the through hole 10; Described angle locating piece 12 right-hand members bottom is connected with supporting screw II11; Described base plate 3 is provided with the screwed hole (not shown), and revolve and in screwed hole and realize and the removably connecting of base plate 3 bottom of described supporting screw II11; Described perpendicularity locating piece 8 relative angles are provided with a square shrinkage pool 13 that is used for placing plunger 9 bore hole ends to locating piece 12 1 sides; Described shrinkage pool 13 bottom surfaces and end face are horizontal plane; Be provided with a cushion block 5 in the described shrinkage pool 13; The bottom surface of described cushion block 5 is parallel with end face with shrinkage pool 13 bottom surfaces with end face; Described perpendicularity locating piece 8 tops are provided with the screwed hole 6 that communicates with shrinkage pool 13; Be connected with screw III7 on the described screwed hole 6; Described screw III7 bottom is connected with cushion block 5.
Operation principle of the present invention is: after the bore hole end of processed plunger 9 inserts in the shrinkage pool 13, the workman is fixed in the shrinkage pool 13 by screw III7 and the cushion block 5 bore hole end with plunger 9 earlier, by dog screw I4 the plunger rod of plunger 9 is being fixed in the through hole 13 of being located at angle locating piece 12 then, unclamp screw III7 and supporting screw II11 at last, the angle locating piece 12 among processed plunger 9 and the present invention and screw III7 and screw I4 are moved on as shown in Figure 4 the anchor clamps together carry out clamping and positioning and carry out the bore hole operation.Because shrinkage pool bottom surface and end face are horizontal plane described in the present invention, and the bottom surface of described cushion block is parallel with end face with the shrinkage pool bottom surface, and plunger is relative all the time static with angle locating piece and supporting screw II in moving process, therefore, the axis of processed plunger its bore hole in the bore hole process and bore hole end face and bottom surface can reach accurate perpendicularity.
