Abstract
The utility model relates to a leak tester for a main oil duct hole of a cylinder block. One end of a stud bolt is provided with a plug 1, and is connected with an air pipe and clamped by a clamping hoop; the other end is provided with a plug 2 which is provided with a tightening grip; the step round end faces of the plug 1 and the plug 2 are provided with grooves which are respectively provided with a seal ring 1 and a seal ring 2; and the seal ring 1 and the seal ring 2 closely abut against the sealing surface during installation and use. When in use, the stud bolt is tightened, so that the seal rings deform, thereby achieving the sealing effect. The method for using the leak tester comprises the following steps: installing the tester on a workpiece, opening the gas valve, introducing 0.5Mpa compressed air, soaking the workpiece in a leak test liquid for 3 minutes, and after the liquid level become still, judging the workpiece for leakage by observing whether the liquid level bubbles continuously. The leak tester is simple for use, and visual and easy for realization.
Description
Technical field
The utility model relates to mechanical field bore seal technology, does not have the sealing of other phase through holes before and after being specially adapted in the middle of the phase through hole, as engine cylinder-body mail gallery holes packoff.
Background technology
At present, the encapsulating method of screw thread double thread is adopted in the cylinder block main oil gallery hole especially threaded oil channel sealing in aperture usually, because there are clearance issues in screw thread mismachining tolerance and threaded engagement, the encapsulating method of screw thread double thread is difficult to reach the purpose of sealing.In addition,, then need to realize sealing by the fluid sealant that presses plate below with bolt clip if the aperture is the oil duct of unthreaded hole, though such method can realize sealing, operate cumbersome, and the screw of easy defective work piece.In order to make cylinder block main oil gallery hole sealing leak test simple and feasible and to improve the reliability of sealing, invented this technology, this technology adopts the encapsulating method of oil duct aperture end face and the pressing of plug end face, use circular seal ring in the plug junction, by tighting a bolt, thereby the crush seal circle reaches the purpose of sealing.
Summary of the invention
It is a kind of at plug step end face design and installation O-ring seal that the purpose of this utility model is to provide, one end plug be connected tracheae and connect, left and right sides plug is connected with stud bolt, other end plug is a handle, O-ring seal is installed in plug and position, working surface joint portion, twist and tighten handle, then stud bolt reaches contraction or loosens the sealing surface leak test of tightening the O-ring seal seal operation as counter-rotation.Can solve the difficult problem of thread seal in the cylinder block main oil gallery leak test or clamping plate sealing, seal with O-ring seal at the face that is adjacent to of plug, by tightening studs, the crush seal circle is realized the sealing of cylinder body main oil gallery front and back end face.Being applicable to that all kinds of centres do not have the sealing of the through hole of cross bore, is through hole packoff a kind of simple in structure, easy to manufacture, easy to use.
A kind of cylinder block main oil gallery of the utility model hole leakage testing device, comprise connection tracheae, clamping stirrup, clip screw, clip nut, O-ring seal 1, plug 1, grip nut, studs, plug 2, O-ring seal 2, tighten handle, it is characterized in that stud bolt one side has plug 1, connects tracheae, grip nut, clamping stirrup, clip screw, clip nut, another side of stud bolt has plug 2, O-ring seal 2, tightens handle, connects the band cone-shaped end pipeline section that tracheae is enclosed within plug 1.
The step circle of plug 1 and plug 2 is adjacent to fluted O-ring seal 1 and the O-ring seal 2 of putting of end face, and there is air hole on the face of cylinder of plug 1, and air hole is ventilated mutually with connecting tracheae, and the endoporus of the tracheae incoming end of plug 1 communicates with the round side opening that is connected the stud bolt end.
Grip nut is equipped with in stud bolt and plug 1 junction, and plug 1 has clamping stirrup chucking with being connected between the tracheae, tightens handle and is contained in plug 2, and being connected between studs and plug 1, the plug 2 is to be threaded.
Be contained in position with working seal surface combination portion in the O-ring seal 1 of plug 1, O-ring seal 2 on the plug 2.
The utility model has the advantages that: the position that is adjacent to face and Work piece sealing surface combination at plug, applying plug design one circle sealed groove, the width of groove is identical with the diameter of rounded washers, height is less than the packing ring diameter, be slightly larger than the packing ring radius, make the O-ring seal distortion by tightening studs, thereby reach the effect of sealing.Facts have proved and adopt this encapsulating method ratio method in the past can better reach seal request, can bear bigger leak test air pressure.The plug 1 at two ends, plug 2 are to tighten sealing by the studs of centre.Plug 1, plug 2 are adjacent to end face and have groove.The O-ring seal groove of packing into, the plug band screw end internal diameter of the seal ring of packing into, compared with prior art, the beneficial effects of the utility model are: can effectively solve end-face hole sealing problem in the cylinder body main oil gallery leak test, can also be used for the sealing of other through holes simultaneously.
