Abstract
The invention discloses an air inflation device for testing air impermeability of an air cylinder. The air inflation device comprises a support (10), a sealing head (20) arranged at one end of the support (10), a shaft (30) connected with the other end of the support (10) and an air connection pipe (40) arranged on the support (10). A hole (11) is formed in one end of the support (10), the hole (11) is communicated with the air connection pipe (40), and the shaft (30) is arranged on an air impermeability test device body (50). A blind hole (12) is formed in the other end of the support (10), wherein the bottom of the blind hole is conical. One end of the shaft (30) is provided with a conical hole (31), and a ball (60) is arranged between the blind hole (12) of the support and the conical hole (31) of the shaft.

The sealing head capable of doing the certain amount of universal movement can compensate the error generated when a fixture clamps the air cylinder and the processing error of the air cylinder itself, so that holes or channels of the air cylinder can be accurately sealed by the sealing head.
Description
Technical field
The present invention relates to the air tightness detection equipment field of part, in particular to a kind of cylinder impermeability, detect the aerating device of use.
Background technology
Automobile engine cylinder is the critical component of engine, and the impermeability of its each passage directly has influence on the overall mass of engine.The calixconcavity part of cylinder bottom surface forms firing chamber jointly with piston top and cylinder inner wall.Cylinder for overhead valve Otto cycle engine, not only spark plug to be installed, also the parts such as valve, valve seating, valve guide bushing, camshaft to be installed, therefore on cylinder, be respectively equipped with spark plug mounting hole, camshaft hole, oil hole, air intake duct, exhaust duct etc.If cylinder seal is bad, serviceability and the efficiency of engine will be had a strong impact on, and to guarantee the impermeability of cylinder integral body, will guarantee that in it, all passages comprise that the positiver sealing of oil duct, chain wheel type chamber, air intake duct, exhaust duct, firing chamber and valve and door line reaches designing requirement, therefore detects just necessary to the impermeability of these projects.Prior art generally adopts the mode of water inspection to carry out, when carrying out water inspection, each valve, hole or passage need to be sealed, and be inflated in cylinder block, product is immersed in the water, by manual observation, whether has Bubble formation to judge that whether the impermeability of product is good.
In sum, when cylinder impermeability detects, how in the situation that guaranteeing that cylinder is sealed inflation to enter in cylinder block be the key that impermeability detects success or not.
Summary of the invention
Technical matters solved by the invention: when cylinder impermeability detects, assurance cylinder is inflated and entered in cylinder block sealed in the situation that.
The invention provides following technical scheme: a kind of cylinder impermeability detects the aerating device of use, comprise support, be arranged on seal head, the axle being connected with the support other end of support one end, the air that is arranged on support radially and is positioned at mid-stent position is taken over, described support one end is offered porose, described hole is taken over and is communicated with air, and described axle is arranged in air tightness detection equipment main body.It is the blind hole of taper that the described support other end offers bottom, and one end of described axle insertion support blind hole offers bellmouth, between described support blind hole and axle bellmouth, lays a ball, and coordinating between described axle and support is clearance fit.
When clamping cylinder, due to the clamping error of fixture or the mismachining tolerance of cylinder itself, may cause all kinds of plugs can not seal various holes or passage completely.Adopt the technical program can solve problems, assurance cylinder is inflated and is entered in cylinder block sealed in the situation that, its principle is as follows: because coordinating between axle and support is clearance fit, therefore, the ball of laying between support blind hole and axle bellmouth can make support make a certain amount of universal movement, and support can drive seal head to make a certain amount of universal movement; The seal head that can make a certain amount of universal movement can compensate the error of fixture clamping cylinder and the mismachining tolerance of cylinder itself, makes seal head hole or the passage of sealing cylinder exactly; Match, air is taken over and to be arranged on support radially and to be positioned at mid-stent position, communicates with the hole of support one end, and so design can guarantee that cylinder inflates and enter in cylinder block sealed in the situation that, makes the result of cylinder airtight test more accurate.Therefore, the technical program has useful technique effect.
As a further improvement on the present invention, described support is connected by register pin with axle, and coordinating between described register pin and axle is clearance fit.
As a further improvement on the present invention, some O shape circles are installed between described axle and support.
As a further improvement on the present invention, also comprise the guiding trestle for the axis of guide, described axle is arranged in air tightness detection equipment main body by guiding trestle.
As a further improvement on the present invention, also comprise the retractor device being arranged on axle, described axle is provided with the shaft shoulder, and the described axle other end is provided with fixed part, and described retractor device is between the shaft shoulder and guiding trestle.
As a further improvement on the present invention, described retractor device is Rectangular Spring, and described fixed part comprises flat head screw and packing ring.
As a further improvement on the present invention, between described axle and guiding trestle, be provided with without oily lining.
