Abstract
The invention belongs to the technical field of self-sealing devices of a water pressure test air cylinder, in particular to a self-sealing device of the water pressure test air cylinder. The self-sealing device of the water pressure test air cylinder comprises a device frame, the sealed air cylinder is arranged on the device frame, a sealing part is arranged at the other end of an ejector rod of the sealed air cylinder, a guide sleeve is arranged outside the ejector rod of the sealed air cylinder, and a rapid pressing plate used for pressing a testing part tightly for testing is arranged below the sealed air cylinder. Due to the characteristic of balanced ejection pressure of the air cylinder, each sealing port can meet the sealing requirement under the action of the guide sleeve, and accurate testing on workpiece leakage is guaranteed.
Description
Technical field
The invention belongs to water testing pressure sealing device technical field, and in particular to a kind of water pressure testing cylinder automatic sealing device.
Background technology
In automobile cast aluminium part, train braking system part and other hydraulic transmission part production processes, when carrying out anti-leak detection, it is general to use anti-leak test sealing device to be detected, now widely used is anti-leak test sealing device Manual sealing device, leading screw rotation is manually set to carry out upper-lower seal workpiece, the staff labor intensity thereby resulted in is big；Efficiency is low；The factors such as the effect difference of sealing, and cause workpiece can not obtain the guarantee of quality consistency.
The content of the invention
A kind of water pressure testing cylinder automatic sealing device is provided it is an object of the invention to solve above-mentioned technical problem, it is intended to which solving current leak-testing sealing device manually makes leading screw rotation carry out upper-lower seal workpiece, and the staff labor intensity thereby resulted in is big；Efficiency is low；The factors such as the effect difference of sealing, and cause workpiece can not obtain quality consistency guarantee technical problem.
To achieve the above object, the present invention is adopted the following technical scheme that：
A kind of water pressure testing cylinder automatic sealing device, including device frame, described device frame is provided with sealing cylinder, the push rod other end of the sealing cylinder is provided with seal, the push rod of the sealing cylinder is externally provided with guide pin bushing, and the lower section of the sealing cylinder, which is provided with, to be used to compressing test block into the quick pressing plate tested.
The characteristics of present invention is by with the equilibrium of cylinder ejector pressure, in the presence of guide pin bushing, makes each seal to obtain seal request, it is ensured that workpiece leak-testing is accurate.
Brief description of the drawings
Fig. 1 show a kind of structural representation of water pressure testing cylinder automatic sealing device provided in an embodiment of the present invention.
Embodiment
Below, the substantive distinguishing features and advantage of the present invention are further described with reference to example, but the invention is not limited in listed embodiment.
Shown in Figure 1, the figure shows a kind of structure of water pressure testing cylinder automatic sealing device provided in an embodiment of the present invention.For convenience of description, it illustrate only the part relevant with the embodiment of the present invention.
Referring to Fig. 1, a kind of water pressure testing cylinder automatic sealing device, including device frame 1, described device frame is provided with sealing cylinder 2, and the other end of push rod 7 of the sealing cylinder 2 is provided with seal 6, and the push rod of the sealing cylinder 2 is externally provided with guide pin bushing（It is not shown）, the lower section of the sealing cylinder 2, which is provided with, to be used to compressing test block into the quick pressing plate 5 tested.
Further, the guide pin bushing is fixed on described device frame 1 by the guide pin bushing fixed mount 3 on described device frame 1.
Further, the guide pin bushing fixed mount 3 is horizontally disposed.
Further, the top of the guide pin bushing fixed mount 3 is provided with connecting plate 4.
The present invention can improve operating efficiency in the leak-testing of automobile cast aluminium part, train braking system part and other hydraulic transmission parts, more importantly can ensure that product quality.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; some improvements and modifications can also be made, these improvements and modifications also should be regarded as protection scope of the present invention.
