Abstract
The utility model provides a leak test block structure is suppressed in water pump hole, is including setting up the clamp plate on cylinder body water pump hole, sealed the pads I who sets up at the clamp plate back, and the clamp plate is fixed on the cylinder body through rigging screw on every side, and its technical essential is: the water pump is downthehole be equipped with with the tight screw in clamp plate middle part matched with school, be equipped with the sealed II of pad between tight screw in school and the clamp plate. It has simple structure, convenient to use, the leakproofness is good, assembly efficiency is high a bit.
Description
Technical field
The utility model belongs to automobile engine and manufactures field, is that leakage test plugging structure is suppressed in a kind of water pump hole specifically,Mainly be applicable to cylinder body advanced development and manually suppress leak test.
Background technology
Cylinder block is by being casted into finished product, between to pass through a lot of operations such as processing, leak test, wherein the airtight experiment of water channel isA requisite procedure, is used for checking the casting flaw of blank. For advanced development, cost of investment is limited, productIndefinite form, so do leak test experiment with kerosene always, only, by the gravity of kerosene, does not have pressure, and experimental result is inaccurate. Water channel handMove while suppressing leak test, shutoff difficulty in water pump hole is higher, is unfavorable for experiment.
Utility model content
The purpose of this utility model is to provide a kind of water pump hole and suppresses leakage test plugging structure, has fundamentally solved above-mentioned askingTopic, its have simple in structure, easy to use, sealing is good, efficiency of assembling is a little high.
For achieving the above object, the utility model provides following technical scheme: leakage test plugging structure is suppressed in this water pump holeComprise the pressing plate being arranged on cylinder block water pump hole, the sealing gasket I that is arranged on the pressing plate back side, pressing plate is around fixed by rigging screwOn cylinder body, its technical essential is: in described water pump hole, be provided with the tight screw in school matching with pressing plate middle part, the tight screw in school and pressureBetween plate, be provided with sealing gasket II.
The beneficial effects of the utility model: profiling base plate (imitative cylinder deck water jacket shape and oil hole), with cylinder deckLocation, hole (hole precision can be lower), in the flank hole tapping (R1/8) of base plate, the hydraulic quick coupler of screwing on is used for connecting leak test simultaneouslyInstrument tracheae. Utilize four support posts and the pressing plate of existing fixture to apply a downward power to cylinder body, make stripper rubber distortionBe close to sealing surface. All the other need the position of shutoff, design manual shutoff frock and are connected with base plate, utilize unsintered tape and finding handMoving installation. The processing technology that this structure press-fits shutoff frock is good, and Whole blanking ensures the position degree of each hole relative datumGood, while having ensured to install with the coordinating of water pump hole face screwed hole. The selected screwed hole of water pump face position ensure again sealing surface eachPosition is stressed evenly, further ensures sealing.

Description of reference numerals:
In Fig. 1: 1 pressing plate, 2 sealing gasket I, the 3 tight screws in school, 4 sealing gasket II, 5 rigging screws, 6 water pump holes;
In Fig. 2: the 7 tight screwed holes in school.
Detailed description of the invention
Below in conjunction with Fig. 1～2, describe content of the present utility model in detail by specific embodiment. Examination is suppressed in this water pump holeLeak plugging structure and comprise the pressing plate being arranged on cylinder block water pump hole, the sealing gasket I2 that is arranged on the pressing plate back side, pressing plate around passes throughRigging screw 5 is fixed on cylinder body. In water pump hole 6, be provided with the tight screw 3 in school matching with pressing plate middle part, the tight screw 3 in school and pressureBetween plate, be provided with sealing gasket II4. Being threaded bore portion is alignment pin, taking water pump hole as benchmark, and matched in clearance. Sealing gasket is logicalHole is corresponding one by one with pressing plate, in the time being installed to water pump face, can not sliding and cause too much wearing and tearing, has ensured the complete of sealing simultaneouslyProperty. By being engaged in reverse school when tight with sealing gasket II4, the reverse chamfering laminating in sealing gasket II4 and cylinder block water pump hole 6, logicalThe power producing when crossing the tight screw 3 in school and tightening makes sealing gasket II4 tightly be fitted in the reverse chamfering in water pump hole, realizes sealing. Tighten cylinderBody water pump hole 6 moments are less than water pump mounting torque. And then the tight screw 3 in reverse school.
Specific operation process: pressing plate 1 is coordinated with sealing gasket 2, with the position of cylinder block water pump hole 6 location sealing pad I2. WillSealing gasket II4 is assemblied on the tight screw 3 in school, then coordinates and tightens with the screwed hole at pressing plate 1 middle part. Until sealing gasket I2 is obviousAfter distortion, tighten six screws on cylinder block water pump hole 6), the tighter screw 3 in school.
