Abstract
The utility model relates to a replaceable small scale holder micrometer of a movable anvil. The utility model comprises a measuring main body, a ball measuring head, a scale holder, a pin roll and a handle, wherein, the measuring main body comprises a spring ring, a movable anvil, a micrometric screw, a locking device and a micrometer head, the ball measuring head is bonded with the scale holder, the scale holder is connected with the measuring main body, and the handle is connected with the scale holder through the pin roll. The utility model can be applied to the size measurement from a groove to a ledge of an impeller, and from a seal groove to an end surface of a hydraulic parts type part, and the thickness measurement of a wheel hub. The ball measuring head can be replaced conveniently. A thermal-insulation protection plate is installed on the handle to minimize the influence of the temperature of hands of an operator to the measuring accuracy of the micrometer during the measuring process.
Description
One. technical field
The utility model relates to the survey instrument field, specifically is the interchangeable little chi frame milscale of a kind of movable gage button.
Two. background technology
Because common outside micrometer is mainly used in the measurement of axial workpiece external diameter, and, measure the size of the groove of impeller to its shoulder for turbine rotor class part; Hydraulic part class part, measure size and the hub thickness size of seal groove to end face, because the chi frame broad of common outside micrometer, the easy and measured piece interference of chi frame causes and can not measure the measuring point of above part with common outside micrometer during measurement.
Three. summary of the invention
The purpose of this utility model provides a kind ofly can measure the movable gage button interchangeable little chi frame milscale of impeller class part groove to the size of shoulder, hydraulic part class part seal groove to the size and the hub thickness size of end face.
The purpose of this utility model is to realize like this, comprise the measurement main body, measure main body and comprise turn, movable gage button, micrometric screw, locking device, micrometer head, also comprise ball contact tip, chi frame, bearing pin, handle, ball contact tip and chi frame are bonding, the chi frame links to each other with the measurement main body, and handle is connected with the chi frame by bearing pin.
The utility model also comprises following architectural features:
1. the chi frame place bonding with ball contact tip leaves the fabrication hole of dismantling ball contact tip.
2. heat insulation backplate is housed on the handle.
Because handle is connected with the chi frame by bearing pin, handle can rotate around bearing pin, can prevent and the measured piece interference, so can be applicable to measure size and the hub thickness size of the groove of impeller to the size of its shoulder, hydraulic part class parts measurement seal groove to end face.At the chi frame place bonding with ball contact tip, leave the fabrication hole of dismounting ball contact tip, can change ball contact tip easily.Heat insulation backplate is housed on the handle, and the temperature of operator's hand is to the influence of miking precision in the time of can reducing to measure.
Four. description of drawings
Fig. 1 is the structural drawing of existing milscale.
Fig. 2 is a kind of embodiment structural drawing of the utility model.
Fig. 3 is the another kind of embodiment structural drawing of the utility model.
Five. embodiment
In conjunction with Fig. 2, the interchangeable little chi frame milscale of this movable gage button comprises the measurement main body, measure main body and comprise turn 5, movable gage button 6, micrometric screw 7, locking device 8, micrometer head 9, it also comprises ball contact tip 1, chi frame 2, bearing pin 3, with the handle 4 of heat insulation backplate.Ball contact tip 1 is bonding with chi frame 2, and chi frame 2 links to each other with the measurement main body, and handle 4 is connected with chi frame 2 by bearing pin 3, and handle 4 can be around bearing pin 3 rotations.
In conjunction with Fig. 3, the interchangeable little chi frame milscale of this movable gage button comprises the measurement main body, measure main body and comprise turn 5, movable gage button 6, micrometric screw 7, locking device 8, micrometer head 9, check and correction post 10, it also comprises ball contact tip 1, chi frame 2, bearing pin 3, with the handle 4 of heat insulation backplate.Ball contact tip 1 is bonding with chi frame 2, and chi frame 2 links to each other with the measurement main body, and handle 4 is connected with chi frame 2 by bearing pin 3, and handle 4 can be around bearing pin 3 rotations.
Claims (3)
1. little chi frame milscale that movable gage button is interchangeable, comprise the measurement main body, measure main body and comprise turn, movable gage button, micrometric screw, locking device, micrometer head, it is characterized in that, also comprise ball contact tip, chi frame, bearing pin, handle, ball contact tip and chi frame are bonding, and the chi frame links to each other with the measurement main body, and handle is connected with the chi frame by bearing pin.
