A sealing plug is arranged between the central spindle protruding head and the connecting rod. The sealing plug is an elastic part and installed on the periphery of the central spindle. The other end of the central spindle is connected with a rotary handle. A supporting rod is arranged on the rotary handle. The hole sealing tool for the leakage detection is simple in structure, small in size, flexible in use, capable of rapidly sealing leakage holes of an engine in a leakage detection test process and applicable to a leakage detection test of the engine.
Description
Technical field
The utility model belongs to motor mounting technology field, and a kind of frock of the hole sealing of leaking hunting for motor particularly is applied to the motor test of leaking hunting.
Background technique
Motor is the product that needs have high-seal, in the process of manufacturing, and the operation of must leaking hunting before the motor frock, the hole sealing frock that is used for leaking hunting is exactly a kind of device that is used for carrying out leak test specially.Traditional engine cylinder cap leak test frock is at leak test plate pad one a monoblock seal rubber pad, mixes sealing clamp again.This old-fashioned sealing means makes that the bottom surface of cylinder head is sealed all over owing to adopted the seal rubber pad of monoblock, can make on the bottom surface of cylinder head some not need the position that seals also sealed like this, influences leak test result's precision.Sealing clamp leak stopping and fastening in want fastening a lot of bolts, not only test process complexity, and bolt is wear testing product easily also.
China invention CN 202735034 U disclose a kind of cylinder head leak test frock, this frock comprises a base plate, be provided with at least one water hole, bottom surface seal rubber pad, at least one air input joint and at least one clamping pressure head support at described base plate, described clamping pressure head support is provided with at least one and clamps pressure head, wherein: water hole, described bottom surface seal rubber pad is used for the water hole, bottom surface of blanket gas cylinder cap, described air input joint is used for supplying gas in cylinder head when leak test, and described clamping pressure head is used for fastening cylinder head.Though this model utility has adopted all-in-one-piece framework, replacing original monoblock seal rubber pad corresponding to the position of leaking hunting on the cylinder head with the fritter seal rubber pad on the framework, can prevent from the leak test process, introducing interference error, easy to operate, also can not damage thread.But this invention complex structure is bulky, uses very dumb.
Summary of the invention
The utility model is in order to overcome the shortcoming that above prior art exists, its technological scheme that provides provide a kind of simple in structure, volume is little, use flexibly, hole sealing frock that can quick-sealing in the process of the test of leaking hunting.
For this reason, it is a kind of be used to the hole sealing frock of leaking hunting that the utility model provides, comprise mandrel and connecting rod, mandrel is installed in the connecting rod, and mandrel one end is provided with and is exposed to the outer mandrel plush copper of connecting rod, is provided with seal plug between mandrel plush copper and the connecting rod, seal plug is elastic component, be installed on the mandrel periphery, the mandrel the other end is connected with rotatable handle, and rotatable handle is provided with strut.When leaking hunting, this frock insertion is wanted in the workpiece mouth of shutoff, depress rotatable handle make mandrel up mention seal plug compressive strain and and Work piece sealing, have auto-lock function after rotatable handle presses down, guarantee that workpiece seals with seal plug in the time of test.
As a kind of the connecting rod periphery is provided with overcoat be used to the further specifying of the hole of leaking hunting sealing frock to described in the utility model, the protection connecting rod also makes things convenient for hand to grab use.
As to described in the utility model a kind of be used to the further specifying of the hole of leaking hunting sealing frock, be provided with packing ring between overcoat and the connecting rod.Packing ring is high-abrasive material, and rotatable handle contact with packing ring rather than directly contacts with overcoat when rotating, thereby when assurance was keeped in repair, it was just passable directly to change packing ring after the gasket wear.
As to described in the utility model a kind of be used to the further specifying of the hole of leaking hunting sealing frock, be provided with stop collar between connecting rod and the seal plug.
As to described in the utility model a kind of be used to the further specifying of the hole of leaking hunting sealing frock, stop collar is for cutting two of formulas open, convenient installation, and have the guide-localization function.
As to described in the utility model a kind of be used to the further specifying of the hole of leaking hunting sealing frock, mandrel is connected by the contiguous block hinge with rotatable handle.
The beneficial effects of the utility model are: owing to be provided with seal plug between the utility model mandrel plush copper and the connecting rod, seal plug is elastic component, is installed on the mandrel periphery, and the described mandrel the other end is connected with rotatable handle, and rotatable handle is provided with strut.Thereby depressing rotatable handle up mentions with seal plug compressive strain and Work piece sealing mandrel.The utility model structure is simple in structure, volume is little, use flexibly, and small opening that can the quick-sealing motor in the process of the test of leaking hunting is applicable to the test of leaking hunting of motor.
