Abstract

The present invention discloses a plunger piston boring positioning device which comprises an angular positioning block (12) installed with a through hole (10) and a verticality positioning block (8) connected with the base board (3). The left end of angular positioning block (12) is connected with a positioning screw I(4). The base of right end of angular positioning block (12) is connected witha supporting screw II(2) which is detachably connected with the base board (3). One side of verticality positioning block (8) relatively to the angle positioning block (12) is installed with a concave hole (13) which is used for placing the boring end of plunger piston (9) and has a base surface and a top surface that are equally horizontal surfaces. A cushion block (5) which has a base surface parallel with the base surface and top surface of concave hole (13) is provided in the concave hole (13). The top part of verticality positioning block (8) is provided with a threaded hole (6) communicated with the concave hole (13). A screw III(7) is connected with the threaded hole (6). The base part of screw III(7) is connected with the cushion block (5). The plunger piston boring positioning device of the invention can guarantee the accurate verticality between the boring axis of processed plunger piston and the top surface and the bottom surface of boring.

Description

Technical field: [0001] The invention relates to a plunger boring positioning device. Background technique: [0002] There is a plunger in the prior art, such as figure 1 As shown, one end of the plunger is provided with two vertically symmetrical planes 1 , and a through hole 2 perpendicular to the two planes 1 is connected between the two planes 1 . At present, in the machining process, in order to ensure the positional accuracy and surface roughness of the above-mentioned through hole 2, workers generally adopt a boring process, that is, rough or fine boring the above-mentioned through hole 2, so that the through hole 2 can be To achieve the required machining accuracy. However, during the boring process, the perpendicularity between the axis of the through hole 2 on the plunger and the two planes 1 cannot achieve good accuracy, thereby affecting the subsequent working state of the plunger. Invention content: [0003] The technical problem to be solved by the present...
