Abstract
The invention discloses an engine cylinder block leakage check device which comprises a base and a top plate, wherein a working table which is used for accommodating an engine cylinder block and plugging holes in the bottom surface of the cylinder block as well as lateral sealing devices located on two sides of the working table is arranged on the base; a cylinder block top surface sealing device and a cylinder block slant sealing device are arranged on the top plate; and the cylinder block lateral sealing device, the cylinder block top surface sealing device and the cylinder block slant sealing device comprise push rods which can stretch out and draw back towards the working table from different directions respectively, and plugs for plugging the holes in the cylinder block are arranged at tops of the push rods. According to the engine cylinder block leakage check device, a hydraulic cylinder pushes the plugs to plug the holes in all directions of the engine cylinder block, the check efficiency is improved, the operation is easier and more convenient, meanwhile, the check errors are reduced, and the check result is more accurate.
Description
Technical field
The present invention relates to verifying attachment, be specifically related to a kind of engine cylinder-body leakage testing device.
Background technology
Engine cylinder-body is one of important composition parts of engine, and its impermeability requires very high.Usual engine cylinder-body is all cast and is formed, the unavoidable defect occurring sand holes and so in the fabrication process, in addition also in cylinder body process, also exists some mismachining tolerances, also can impact the impermeability of cylinder body, therefore engine cylinder-body needs after machining to carry out air-leakage test.Then, in existing cylinder body air tight test, be all directly with some stoppers, each hole on cylinder body is blocked, then carry out hermeticity experiment, and this method, checkability is low, and labor intensity is large, and the error simultaneously detected is also large.
Summary of the invention
For above-mentioned the deficiencies in the prior art, technical matters to be solved by this invention is: how to provide a kind of checkability high, operate easy and convenient, the engine cylinder-body leakage testing device that verify error is little.
In order to solve the problems of the technologies described above, present invention employs following technical scheme:
A kind of engine cylinder-body leakage testing device, comprise base and top board, described base is provided with the bolt mounting holes for firm banking, for place engine cylinder-body and on shutoff cylinder body bottom surface hole worktable and be positioned at the cylinder body lateral seal device of worktable both sides, described top board is provided with cylinder deck packoff and the oblique packoff of cylinder body, described cylinder body lateral seal device comprises the support be arranged on base, described support is provided with hydraulic cylinder I, described hydraulic cylinder I comprises and can stretch and horizontally disposed push rod I towards described worktable direction, described push rod I top is provided with the plug of hole on shutoff side of cylinder block, described cylinder deck packoff comprises the hydraulic cylinder II be arranged on top board, described hydraulic cylinder II comprises and can stretch and the push rod II arranged straight down towards described worktable direction, described push rod II top is provided with the plug of hole on shutoff cylinder deck, the oblique packoff of described cylinder body comprises the hydraulic cylinder III be arranged on top board, described hydraulic cylinder III comprises and can stretch and the push rod III of downward-sloping setting towards described worktable direction, described push rod III top is provided with the plug for shutoff side of cylinder block hole obliquely.
In the present invention, engine cylinder-body is placed on the table, adjustment cylinder body position on the table, start each hydraulic cylinder, push rod drives plug and carries out shutoff to the hole on each face of cylinder body, and under the effect of the push rod II ordered about at hydraulic cylinder II, cylinder body bottom surface is pressed on worktable surface downwards, cylinder body bottom surface is sealed simultaneously, carry out air tight test more afterwards.Structure of the present invention is simple, controls plug carry out shutoff to the hole on each face of cylinder body with hydraulic cylinder, and pattern that is relative and a hole, an artificial hole in the past carries out shutoff, and improve checkability, also make operation more easy and convenient, verify error is less simultaneously.
As optimization, surface and the described bench top of described plug are respectively equipped with resilient rubbber cushion.Improve the sealing effectiveness to each hole, reduce verify error, make assay more accurate.
As optimization, described bench top is provided with register pin straight up.Engine cylinder-body is placed and makes on the table, utilize register pin to be inserted in the corresponding hole of cylinder body, more enough fast cylinder body to be located on the table, make the plug of all directions better carry out shutoff to hole.
In sum, beneficial effect of the present invention is: the present invention utilizes Hydraulic Cylinder plug to carry out shutoff to the hole in engine cylinder-body all directions, improves checkability, operates more easy and convenient, reduce verify error simultaneously, make assay more accurate.
