Abstract
The utility model discloses an axle housing air tightness tester, which solves the problems of poor processing quality, affection on driving safety and the like of existing axle housings without testing of air tightness. The axle housing air tightness tester comprises end plugs (2) and a flange plug (10), the end plugs (2) are disposed at two ends of an axle housing (1), and the flange plug (10) is mounted on a straight opening of the axle housing (1). Therefore, the axle housing air tightness tester has the advantages of simple structure, easy operation, capability of guaranteeing processing quality and the like.
Description
Affiliated technical field the utility model relates to a kind of test unit, relates in particular to a kind of axle housing tightness test device.
The background technology axle housing is one of important spare part on automobile and the engineering machinery, the main material of producing axle housing is a cast iron, in the process of producing axle housing, because a variety of causes easily causes producing in the foundry goods pore or sand holes, and oil leakage phenomenon easily takes place in pore on the axle housing or sand holes, cause the parts accelerated wear test in the axle housing, reduced serviceable life, it is peaceful to influence driving when serious, at present, on the market axle housing is not carried out air-tight test.
The summary of the invention the purpose of this utility model provide a kind of simple, can detect the bubble-tight axle housing tightness test of axle housing device again.
For achieving the above object, the utility model axle housing tightness test device comprises axle housing, also comprises end plug and blind flange, and the end plug is arranged on the axle housing two ends, and blind flange is installed on the straight mouth of axle housing.
Described end plug is made up of T word shape screw rod, rubber sleeve, T word shape packing ring and nut, the T word shape screw rod that is slidingly matched with axle housing two ends hole is provided with the rubber sleeve that can place in the hole of axle housing two ends, also be provided with T word shape packing ring between rubber sleeve and nut, the T word shape washer face that contacts with rubber sleeve also contacts with the axle housing end face.
Described blind flange is made up of strut, pull bar, blind flange, O type rubber strip, rubber blanket and nut, the strut that is arranged in the axle housing is connected with blind flange by pull bar, blind flange is provided with O type rubber strip with the end face that the straight mouthful end face of axle housing contacts, and the pull bar between nut and the blind flange is provided with rubber blanket.
Described blind flange is provided with the hole that can be installed into air valve.
After adopting this structure, owing to be provided with the end plug at the axle housing two ends and on the straight mouth of axle housing, blind flange be installed, make and formed a sealed space in the axle housing, when pressurized air after the gas admittance valve on the blind flange enters, the axle housing outside surface is coated with brushes saponification liquor, observe the axle housing outside surface then, all have that bubble emerges be the gas leakage position, and carry out mark, behind the exhaust pressure relief to mark polishing welding, do not have leakage until axle housing and end, guarantee the crudy purpose thereby reach.
The utility model is described in further detail below in conjunction with drawings and Examples for description of drawings.
Accompanying drawing is that the master of the utility model axle housing tightness test device looks synoptic diagram.
Among the figure: 1. axle housing 2. end plugs 3. rubber sleeve 4.T word shape packing ring 5.T word shape screw rods 6. blind flanges 7. struts 8. rubber blankets 9. pull bars 10. blind flanges.
