Abstract
The utility model discloses a contact-type auxiliary device for on-line measuring the hole position of a small hole, which is characterized by comprising a matched cylindrical end (3) capable of being arranged inside a small hole (4) to be measured and a standard cylindrical end (2) with its geometrical precision equal to or higher than the precision of the small hole. The matched cylindrical end (3) is arranged inside the small hole (4) to be measured, so that the direct measurement of the pole position of the small hole is converted into the indirect measurement of the position of the cylindrical body. Therefore, the measurement request is satisfied. The cost is lowered and the efficiency is improved.
Description
Technical field
The utility model relates to contact on-line measurement aperture hole positioning auxiliary device.
Background technology
Present machining tool such as CNC milling machine, has the on-line measurement function, the applied probe of contact on-line measurement is the gauge head of fixed outer diameter, when the aperture for the treatment of gaging hole is suitable with the gauge head external diameter less than gauge head external diameter or aperture, the contact on-line measurement can not be changed gauge head, so can't finish the measurement for the treatment of position, gaging hole hole.If will treat that gaging hole takes off lathe and measures on three coordinate measuring machine, though three coordinate measuring machine can be changed the aperture that the gauge head of little external diameter is measured aperture, can increase manufacturing process like this, raise the cost, lower efficiency.
Summary of the invention:
The technical problems to be solved in the utility model is to provide a kind of servicing unit that can realize position, contact on-line measurement aperture hole, thereby reduces cost, and raises the efficiency.
For solving the problems of the technologies described above, the utility model provides a kind of contact on-line measurement aperture hole positioning auxiliary device, it is characterized in that: comprise a cooperation cylindrical end that can be installed in the aperture to be measured, a geometric accuracy is equal to or higher than the standard round styletable of aperture required precision, described cooperation cylindrical end and aperture to be measured form interference fits, described cooperation cylindrical end and standard round styletable form integral body, and the two is coaxial, and whole coaxial with aperture.
The utility model has following good effect than prior art.The servicing unit of position, a kind of contact on-line measurement aperture hole of the present utility model, it is installed in the aperture to be measured, can converts the direct measurement of position, aperture hole to indirect measurement, and can satisfy and measure requirement the cylinder position, reduce cost, improved efficient.
Description of drawings
Fig. 1 is the schematic perspective view of a kind of contact on-line measurement aperture of the present utility model hole positioning auxiliary device.
Fig. 1 is the use schematic diagram of a kind of contact on-line measurement aperture of the present utility model hole positioning auxiliary device.
The specific embodiment
Below in conjunction with embodiment the utility model is further described.
Fig. 1 is a kind of contact on-line measurement aperture of the present utility model hole positioning auxiliary device, it is characterized in that: comprise a cooperation cylindrical end 3 that can be installed in the aperture 4 to be measured, a geometric accuracy equals to be higher than the standard round styletable 2 of aperture required precision, described cooperation cylindrical end 3 forms interference fits with aperture 4 to be measured, described cooperation cylindrical end 3 forms whole with standard round styletable 2, the two is coaxial, and whole coaxial with aperture.
Fig. 2 is the best embodiment of use of of servicing unit of the present utility model, and gauge head 1 is the typical gauge head of on-line measurement system, and can not change, and hole 4 is apertures to be measured, needs to measure its position, hole.During this position, aperture 4 hole of on-line measurement, on-line measurement aperture hole positioning auxiliary device is installed in the hole, make and cooperate cylindrical end 3 and hole 4 to form interference fits, cooperate cylindrical end 3 to go deep into hole 4 interior a section, guarantee to cooperate cylindrical end 3 coaxial with hole 4, and install firmly, the length of fits best cylindrical end 3 is shorter than the degree of depth in hole 4.Cooperate and adopt the transition connected mode between cylindrical end 3 and the standard round styletable 2, the two forms whole, and the geometric accuracy of standard round styletable 2 is equal to or higher than aperture precision 1-2 level.
The measurement data of position, on-line measurement aperture hole provides according to contact on-line measurement aperture hole positioning auxiliary device, and data are standard round styletable 2 appearance millet cake positions.During measurement, contact on-line measurement aperture hole positioning auxiliary device is installed, operation contact on-line measurement system records standard round styletable 2 appearance millet cake positions, to record the position, hole of aperture 4 to be measured.
Claims (5)
1. a contact on-line measurement aperture hole positioning auxiliary device is characterized in that comprising a cooperation cylindrical end (3) that can be installed in the aperture to be measured (4), and a geometric accuracy is equal to or higher than the standard round styletable (2) of aperture required precision.
