Abstract
The utility model discloses a checking fixture for a crankshaft semicircular hole of a cylinder block of an internal combustion engine, which comprises a go end and a no-go end connected with each other. A handle is fixedly connected to the other end of the go end and is about 5mm smaller than a semicircular hole to be checked in size. The checking fixture is suitable for determining qualification of semicircular holes, size of a nose of a boring tool needs no measurement, each workpiece can be quickly determined on qualification, and the checking fixture is quite convenient to use in batch production.
Description
Technical field
The utility model relates to a kind of detection method of semicircle orifice, is applicable to the semicircle orifice split surface not on the semicircle central plane, mainly is a kind of IC engine cylinder block bent axle semicircle orifice detection tool.
Background technology
In the process of gasoline engine cylinder body machining crankshafts hole, first heavy boring semicircle orifice, cylinder block and main bearing cover later half right boring, right boring crankshaft hole then.The heavy boring semicircle orifice, the semicircle orifice size must with the semicircle orifice consistent size of main beating cap, each process dimension control of gasoline engine cylinder body is all very strict, each workpiece all needs to detect.Semicircle orifice subdivision plane not on the semicircle central plane, with general measurers such as vernier caliper be difficult to measure, the size confidence level is not also high.Carry out Working Procedure Controlling by measuring boring cutter point of a knife size in the production, bother very much, and consuming time, be inappropriate for batch process.
The utility model content
The utility model technical matters to be solved provides a kind of IC engine cylinder block bent axle semicircle orifice detection tool; It is suitable for judging that whether qualified semicircle orifice is; Need not measure boring cutter point of a knife size; Whether each workpiece can be judged very soon qualified, in batch production process, uses very convenient.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of IC engine cylinder block bent axle semicircle orifice detection tool includes go side and not-go-end, and it is characterized in that: said go side and not-go-end interconnect, and an other end of said not-go-end is fixedly connected with handle.
Said handle portion size is than little 5 millimeter of semicircle orifice size to be detected.
Tolerance is controlled by not-go-end by go side control, last tolerance under the tested semicircle orifice.The utility model is inserted semicircle orifice, if the go side is passed through, not-go-end stops and can not pass through, and explains that hole dimension descends within the margin tolerance above that.The go side size is confirmed: according to the semicircle orifice tolerance range and down tolerance press plain limit gage drift national standard and calculate definitely, length is identical with semicircle orifice length.The not-go-end size is confirmed: according to the semicircle orifice tolerance range and go up tolerance and press plain limit gage no-go gage national standard and calculate definite.The handle portion size is confirmed: than little 5 millimeter of tested semicircle orifice size.So just can the third gear semicircle orifice in the middle of the cylinder block be detected.Solve a difficult problem of using vernier caliper measurement to be difficult to find the actual diameter in hole, also do not needed frequently to measure boring cutter point of a knife size.
The utility model has the advantages that:
The utility model is suitable for judging that whether qualified semicircle orifice is, need not measure boring cutter point of a knife size, and whether each workpiece can be judged very soon qualified, in batch production process, uses very convenient.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Referring to Fig. 1, a kind of IC engine cylinder block bent axle semicircle orifice detection tool includes go side 1 and not-go-end 2: said go side 1 interconnects with not-go-end 2, and an other end of said not-go-end 2 is fixedly connected with handle 3.
Said handle 3 portion sizes are than little 5 millimeter of semicircle orifice size to be detected.
During use, the utility model is inserted semicircle orifice, if the go side is passed through, not-go-end stops and can not pass through, and explains that hole dimension descends within the margin tolerance above that.
