Description
Technical field
The present invention relates to a kind of set pressure detecting trial assemblies of vehicle cylinder to set.
Background technique
Existing automobile cylinder sleeve detection method is by automobile cylinder sleeve alignment light source, and observing by the naked eye automobile inboard wall of cylinder liner is The no sand hole for having big, intensive row.
Artificial detection is not only time-consuming and laborious, it is also possible to because human negligence does not find big, intensive sand hole, allow bad Product outflow, causes customer complaint；Simultaneously for fine and closely woven hole, just unlikely had found by human eye.
Summary of the invention
The present invention has made improvements in view of the above-mentioned problems of the prior art, i.e., the technical problem to be solved by the present invention is to A kind of set pressure detecting trial assembly of vehicle cylinder is provided to set, structure is simple, and it is easy to use, reduce operator.
In order to solve the above-mentioned technical problem, it the technical scheme is that a kind of set pressure detecting trial assembly of vehicle cylinder is set, wraps Pedestal is included, a lifting cylinder is provided with above the pedestal and drives the upper tooling for being used to compress cylinder sleeve moved up and down, institute The movable block for being additionally provided on pedestal and driving transverse shifting by a lateral cylinder is stated, is provided at least one on the movable block The variform lower tooling for seal cylinder sleeve is provided with the inlet channel being connected with an air inlet pipe in the lower tooling, The venthole supplied in promising cylinder sleeve is arranged in the lower tooling top, further includes the pressure by being connected in an appendix and cylinder sleeve Power table.
Further, it is provided with positioning pin on the movable block, is provided in the lower tooling and matches with positioning pin Location hole.
It further, further include First Five-Year Plan breather valve, which is connected with an air feed equipment, five breather valves An outlet side be connected by one first pressure reducing valve with lateral cylinder, another outlet side by a filtering pressure reducing valve and rise Sending down abnormally ascending cylinder is connected.
It further, further include one for the control cabinet of cylinder sleeve detection time and cylinder sleeve inflationtime to be arranged.
Further, guide rail is provided on the pedestal, the movable block moves under the driving of lateral cylinder along guide rail.
Further, the lower tooling side wall is provided with sealing ring.
Further, the pedestal side is additionally provided with the toggle of the flexible stroke of control lateral cylinder.
Further, the pedestal side is additionally provided with equal with lower tooling quantity for controlling lower tooling gas supply opening and closing Button.
Further, it is provided with one second pressure reducing valve in the air inlet pipe and is connected with air feed equipment.
It further, further include that a pair of of cylinder liner surface sprays the spray head for being also easy to produce the clean water of bubble.
Compared with prior art, it the invention has the following advantages: the present invention only needs one man operation, can find in time Automobile inboard wall of cylinder liner is big, intensive sand hole, prevents defective products from flowing out, reaches time saving and energy saving, saves the purpose of economic cost.
The present invention will be further described in detail with reference to the accompanying drawings and detailed description.
Detailed description of the invention
Fig. 1 is the organigram at one visual angle of the embodiment of the present invention.
Fig. 2 is the organigram at another visual angle of the embodiment of the present invention.
In figure: 1- pedestal, 11- guide rail, 12- toggle, 13- button, 2- lifting cylinder, 3- lateral cylinder, the upper tooling of 4-, 5- Movable block, tooling under 51-, 52- venthole, five breather valve of 6-, 61- filtering pressure reducing valve, 7- pressure gauge, the second pressure reducing valve of 8-, 9- Control cabinet.
Specific embodiment
Embodiment one: as shown in Fig. 1~2, a kind of set pressure detecting trial assembly of vehicle cylinder is set, including pedestal 1, on the pedestal Side is provided with a lifting cylinder 2 and drives the upper tooling 4 for being used to compress cylinder sleeve moved up and down, is additionally provided on the pedestal The movable block 5 of transverse shifting is driven by a lateral cylinder 4, there are two variform for sealing for setting on the movable block The lower tooling 51 of cylinder sleeve is provided with the inlet channel being connected with an air inlet pipe in the lower tooling, and the lower tooling top is set It is equipped with the venthole 52 to supply in cylinder sleeve, further includes the pressure gauge 7 by being connected in an appendix and cylinder sleeve.
In the present embodiment, it is provided with positioning pin on the movable block, is provided in the lower tooling and matches with positioning pin Location hole, be conveniently replaceable lower tooling of different shapes, adapt to cylinder sleeve of different shapes and detected.
It further include First Five-Year Plan breather valve 6 in the present embodiment, which is connected with an air feed equipment, and five is logical One outlet side of air valve is connected by one first pressure reducing valve with lateral cylinder, another outlet side passes through a filtering pressure reducing valve 61 are connected with lifting cylinder.
It further include one for the control cabinet 9 of cylinder sleeve detection time and cylinder sleeve inflationtime to be arranged in the present embodiment.
In the present embodiment, guide rail 11 is provided on the pedestal, the movable block is under the driving of lateral cylinder along guide rail It is mobile.
In the present embodiment, the lower tooling side wall is provided with sealing ring.
In the present embodiment, the pedestal side is additionally provided with the toggle 12 of the flexible stroke of control lateral cylinder.
In the present embodiment, the pedestal side is additionally provided with equal with lower tooling quantity for controlling lower tooling gas supply opening and closing Button 13.
In the present embodiment, it is provided with one second pressure reducing valve 8 in the air inlet pipe and is connected with air feed equipment.
In the present embodiment, further includes the spray head that a pair of of cylinder liner surface sprinkling is also easy to produce the clean water of bubble, is not shown in the figure, Convenient for being observed visually some tiny holes of cylinder liner surface, the gas output of those holes is not easy that pressure gauge is allowed quickly to fall back to zero Position, but pressure value is unstable.The bubble persistently occurred by cylinder liner surface, to detect aperture position.
In use, control cabinet setting cylinder sleeve detection time and cylinder sleeve inflationtime are first passed through, it then will be corresponding by toggle Lower tooling be moved to immediately below tooling, cylinder sleeve is mounted in lower tooling, upper tooling is pressed in by upper work by lifting cylinder Surface is filled, the air pressure of gas in cylinder sleeve is then adjusted by the second decompression table, is inflated after setting into cylinder sleeve；Viewing pressure Power table shows that the inboard wall of cylinder liner has big or intensive sand hole if gauge hand quickly falls back to zero-bit, if pointer is kept Then show that the cylinder sleeve is big or intensive sand hole, is qualified products；If gauge hand shaking is unstable, may deposit In tiny hole, spray head is also easy to produce the clean water of bubble to cylinder liner surface sprinkling, has seen whether that bubble persistently generates, has and continue Then there are holes on surface for bubble, are substandard product, if bubble-free, may seal and go wrong, need to check.Certainly sprinkling When clean water, the region that tooling is glanded is avoided in the position of adjustable lower tooling.
The foregoing is merely presently preferred embodiments of the present invention, all equivalent changes done according to scope of the present invention patent with Modification, is all covered by the present invention.
