Engine cylinder body leakage test plugging tool described in the utility model, the closure bar include work department and handle portion, And spacing board is provided between work department and handle portion.

Engine cylinder body leakage test plugging tool described in the utility model, it is described block bar work department section be it is rectangular, The closure ring is provided with square hole corresponding with rectangular work department, realizes that blocking bar fixes the circumferential direction for blocking ring.

Engine cylinder body leakage test plugging tool described in the utility model, the closure ring can be longitudinal free on blocking bar Sliding.

Engine cylinder body leakage test plugging tool described in the utility model is provided with several uniform intervals on the closure bar Compression bar location hole.

Engine cylinder body leakage test plugging tool described in the utility model, the free end of the work department are provided with detachably Plug at end part ring, and the length of plug at end part ring be greater than it is other block rings length.

Engine cylinder body leakage test plugging tool described in the utility model, the closure ring are made of elastic rubber, or Person is made of nylon material.

Engine cylinder body leakage test plugging tool described in the utility model, the closure ring are set in interior by inner ring and entirety Outer ring composition on ring, the inner ring are made by rigid material, and outer ring is made by elastic rubber or nylon material.

Engine cylinder body leakage test plugging tool described in the utility model is provided with anti-skidding annular knurl in the handle portion.

The utility model has the beneficial effects that: realizing engine product by blocking bar and blocking the cooperation of ring and existing After completing assembly base bearing flap, leak test is carried out directly on leakage tester, avoids disassembly main beating cap, substantially increases detection Efficiency, and the use that fixed main shaft holds the bolt of lid has been saved, reduce production cost.

Specific embodiment

In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation Example, is further elaborated the utility model technology.It should be appreciated that specific embodiment described herein is only used to It explains the utility model, is not used to limit the utility model.

Embodiment 1:

As shown in figure 3, be provided with inclined oil hole of air 411 on the crankshaft semicircle orifice 41 of engine cylinder body 4, due to inclined oil hole of air 411 with Cylinder body main oil gallery communicates, it is necessary to block oilhole 411 just and can be carried out the leak test of oil duct, so the utility model devises a kind of hair Motivation cylinder body leakage test plugging tool, realizes the target of quick blocking leak test.As shown in Figure 1, engine cylinder body leakage test plugging work Tool, including block bar 1 and block ring 2, each crankshaft semicircle orifice 41 of engine cylinder body 4 can correspond to a closure ring 2, block Ring 2, which is serially connected in, to be blocked on bar 1, can be applied downward external force on blocking bar 1, to block the inclined oil hole of air 411 of engine, and be reached To the condition of leak test.

Specifically, the closure bar 1 includes work department 12 and handle portion 11, and set between work department 12 and handle portion 11 It is equipped with spacing board 3, to facilitate the installation and removal of leakage test plugging tool, annular knurl is additionally provided in the handle portion 11, to prevent It skids.

It is described block bar 1 work department 12 section be it is rectangular, the closure ring 2 is provided with corresponding with rectangular work department 12 Square hole 23 (shown in Fig. 4), realize that the circumferential direction for blocking 1 pair of bar closure ring 2 is fixed；The closure ring 2 can be longitudinal on blocking bar 1 It is free to slide, to be adapted to the engine cylinder body of different dimensions；Several evenly spaced pressures are provided on the closure bar 1 Bar location hole 13 is blocked on bar 1 with facilitating compression bar 5 to be scheduled on, and is not easy to skid.

The free end of the work department 12 is provided with dismountable plug at end part ring 2, and the length of plug at end part ring 2 is big In other length for blocking ring 2.The closure ring 2 is made of elastic rubber, or is made of nylon material.

This leakage test plugging tool is in use, as shown in Fig. 2, pass through crankshaft semicircle orifice 41 for capping tools, so that each song The corresponding closure ring 2 in the position of axis semicircle orifice 41, then withstands closure bar for compression bar 5, downward by hold-down mechanism driving compression bar 5 Closure bar is pushed down, so that blocking ring 2 blocks inclined oil hole of air 411, leakage experiment can be started.
