Embodiment
Core of the present utility model is to provide a kind of cubing for detecting the engine cylinder cover spark-plug hole degree of depth, and its structure is simple, and the convenience that can realize the spark-plug hole degree of depth accurately detects, and can substitute three coordinate measuring machine, thus reduce production cost.
In order to make those skilled in the art understand the technical solution of the utility model better, below in conjunction with accompanying drawing, the utility model is further detailed.
Please refer to Fig. 1, Fig. 1 is the structural representation of a kind of embodiment of cubing provided by the utility model.
In a kind of embodiment, the cubing that the utility model provides is for detecting the engine cylinder cover spark-plug hole degree of depth, this cubing comprises plug 1, one end of described plug 1 has the reference field 2 for fitting with spark plug end face to be detected, one end that described plug 1 arranges described reference field 2 is provided with location division 3, the end of described location division 3 is provided with bulb 4, and described location division 3 offers external thread, and the internal thread of described external thread and spark-plug hole to be detected matches; Described cubing also comprises the measuring mechanism 5 detecting described bulb 4 and engine cylinder cover bottom surface distance.In testing process, the location division 3 of plug 1 one end is screwed in spark-plug hole, when reference field 2 is fitted with spark-plug hole end face, bulb 4 on location division 3 is through spark-plug hole, and protrude from the bottom surface of cylinder cap, by measuring mechanism 5 measure-ball 4 relative to bottom surface distance, thus calculate the distance of spark-plug hole end face to bottom surface, to realize the detection of the spark-plug hole degree of depth.
Particularly, above-mentioned measuring mechanism 5 is dial gauge mechanism, and dial gauge mechanism is the testing tool that this area is commonly used, and stable performance, accuracy of detection is higher.
The parameter such as externally threaded pitch, external diameter that above-mentioned location division 3 is offered should match with the spark-plug hole internal thread of spark plug to be detected, and when the spark plug specification detected is different, externally threaded each parameter answers respective change.
Like this, because spark-plug hole is threaded hole, external thread then on location division 3 and the internal screw-thread screw of spark-plug hole, thus achieve the location of plug 1, when plug 1 insert spark-plug hole measure time, can directly be fixed in spark-plug hole by screw thread, when the reference field 2 on plug 1 is fitted with spark-plug hole end face, plug 1 i.e. fix in position, now, hand can spare by operating personnel, for holding up steady setting or the edge-on cylinder cap put, measuring mechanism fits in cylinder cover bottom surface by another hand, carries out measuring and reading.This detection tool structure is simple, and the convenience that can realize the spark-plug hole degree of depth accurately detects, and can substitute three coordinate measuring machine, thus reduce production cost.
Particularly, above-mentioned plug 1 comprises Handheld Division 11 and reference section 12, and described reference field 2 is formed at the end face of described reference section 12 towards described location division 3.
Plug 1 is cylindrical structure, and the external diameter of described Handheld Division 11 is equal with the external diameter of described reference section 12, to simplify the structure of plug 1, reduces the difficulty of processing of plug 1, saves processing cost.Apparently, plug 1 is also not limited to cylindrical structure, as long as can realize effect that is hand-held and installation location division 3, plug 1 can be also square structure for the xsect with suitable length, or xsect is leg-of-mutton structure.
In order to increasing friction force, be convenient to hand-held, annular knurl can be provided with in periphery, Handheld Division 11 or the structures such as antiskid glue cushion are set.
Mode above only by illustrating describes some one exemplary embodiment of the present utility model, undoubtedly, for those of ordinary skill in the art, when not departing from spirit and scope of the present utility model, can revise described embodiment by various different mode.Therefore, above-mentioned accompanying drawing is illustrative with being described in essence, should not be construed as the restriction to the utility model claims.
