Abstract

The utility model provides a detection device for leak tightness of wheels. The detection device comprises an upper die and a lower die vertically arranged, an actuating mechanism and a circumscribed meter; the actuating mechanism drives the upper die to do the reciprocating movement relative to the lower die; concave arcs matched with the wheels are formed respectively at the ends opposite to the upper and the lower dies; sealing washers for sealing the wheels are arranged at the front ends of the concave arcs; the upper die is connected with detection gas through a pipeline; and a sensor connected with the meter is arranged in the lower die. The utility model adopts the upper and lower dies for sealing the wheels, and also adopts the structure that the upper die is filled with gas, the lower die is used for detecting leakage points, and the meter is used for displaying; and only areas of the wheels, which are required for detection, are required to be sealed in operation. Therefore, the detection accuracy is effectively improved; the energy consumption is reduced; the detection tempo is quickened; and the utility model has the advantages of high automation degree, high inspection efficiency and precision. The utility model is particularly suitable for detection of automobile wheels, but is not limited to the detection of the automobile wheels, and can be used for leak tightness detection on any wheels.

Description

A kind of device that is used for the detection of wheel sealing

Technical field

The utility model relates to a kind of pick-up unit, particularly a kind of device that is used for the detection of wheel sealing.

Background technology

Existing wheel detection mode probably has two kinds.One is the shutoff wheel, charges into pressurized air then, puts into water and sees if there is the bubble appearance, has the bubble explanation that leak source is arranged, otherwise does not have leak source.It two is at wheel outside coating suds, sees if there is soap bubble and occurs, and has the soap bubble explanation that leak source is arranged, otherwise does not have leak source.Above-mentioned two kinds of methods all need to rely on the observation of human eye, so it is poor to detect consistance, detection efficiency is low, and can't realize automated production.

Summary of the invention

The purpose of this utility model is the defective at above-mentioned prior art, and a kind of device that the wheel sealing detects that is used for is provided, and has and improves the precision that detects, and cuts down the consumption of energy, and improves and detects the high advantage of beat automaticity.

The technical scheme taked of the utility model is to achieve these goals: a kind ofly be used for the device that the wheel sealing detects, comprise vertically disposed mold and bed die, topworks and external instrument, topworks drives the relative bed die of mold and moves reciprocatingly, that end that upper and lower mould is relative is respectively equipped with the concave arc that matches with described wheel, the front end of concave arc is provided with the seal gasket of the described wheel of shutoff, mold links to each other with detected gas by pipeline, and bed die inside is provided with the sensor that links to each other with instrument.The utility model has adopted the upper and lower mould of shutoff wheel, and charge into gas by mold, the structure that bed die detects leak source and shown by instrument, the zone that only needs seal wheel to detect in the enforcement, effectively raise the precision of detection, reduce energy consumption, improved the detection beat, had automaticity height, checkability height and the high advantage of accuracy.

As preferably, described gas is the nitrogen hydrogen gas mixture.

For a plurality of wheels of one-time detection, the concave arc on the described mould up and down is a plurality of.

The beneficial effects of the utility model are: compared to existing technology, the utility model has adopted the upper and lower mould of shutoff wheel, and charge into gas by mold, the structure that bed die detects leak source and shown by instrument, the zone that only needs seal wheel to detect in the enforcement effectively raises the precision of detection, has reduced energy consumption, improve the detection beat, had automaticity height, checkability height and the high advantage of accuracy.The inapplicable novel detection that is particularly suitable for automotive wheel, but be not limited to the detection of automotive wheel, the sealing that can be used for any wheel detects.

Description of drawings

Fig. 1 is the front view of the described package seal checker of the utility model embodiment;

Fig. 2 is the side view of Fig. 1.

Among the figure: 1 mold, 1.1 concave arcs, 2 bed dies, 3 instrument, 4 wheels, 5 topworkies.

Embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments, but not as to qualification of the present utility model.

As shown in Figures 1 and 2, the described a kind of device that the wheel sealing detects that is used for of the utility model embodiment comprises vertically disposed mold 1 and bed die 2, topworks 5 and external instrument 3.Topworks 5 drives mold 1 relative bed die 2 and moves reciprocatingly, and topworks 5 can be hydraulic stem, atmospheric pressure pole, electric pushrod or electrically driven (operated) screw rod.Instrument 3 is used for detection of leaks numerical value and warning.Upper and lower mould 1,2 those relative ends are respectively equipped with the concave arc 1.1 that matches with described wheel 4, and the front end of concave arc 1.1 is provided with the seal gasket (not shown) of the described wheel 4 of shutoff.For a plurality of wheels 4 of one-time detection, the concave arc 1.1 on the described mould 1,2 up and down is a plurality of (referring to Fig. 2).Mold 1 is by the pipeline (not shown) that links to each other with detected gas, and as preferably, described gas is the nitrogen hydrogen gas mixture.It is not shown that bed die 2 inside are provided with the sensor that links to each other with instrument 3.

The course of work of the utility model embodiment is: shown in Fig. 1-2, for steel welding wheel 4, at first tested wheel 4 is aligned with weld seam and be placed on the bed die 2, mold 1 compresses under the effect of topworks 5, rely on the seal gasket on the mold 1 that wheel 4 weld seam top seals are become a little cavity, also there is seal gasket that the weld seam lower seal is formed a cavity on the bed die 2, in the cavity that mold 1 forms, charge into the nitrogen hydrogen gas mixture, the numerical value that in the cavity that bed die 2 forms, leaks then by sensor, the numerical value that leaks shows on instrument 3, instrument 3 can be provided with qualified standard, defective with regard to output alarm signal, realize detecting automatically.

In sum, the utility model has adopted the upper and lower mould of shutoff wheel, and charge into gas by mold, the structure that bed die detects leak source and shown by instrument, the zone that only needs seal wheel to detect in the enforcement effectively raises the precision of detection, has reduced energy consumption, improve the detection beat, had automaticity height, checkability height and the high advantage of accuracy.

Above-described embodiment, the utility model embodiment a kind of more preferably just, the common variation that those skilled in the art carries out in the technical solutions of the utility model scope and replacing all should be included in the protection domain of the present utility model.
