Abstract
The invention relates to the technical field of measurement devices, in particular to a hole diameter measuring tool. The hole diameter measuring tool comprises a dial gauge, a fixed measurement assembly is fixed to the center of the dial gauge, and a movable measurement assembly is arranged at the left end of the dial gauge. The movable measurement assembly comprises a connection plate arranged between a dial gauge measurement head and a dial gauge measurement rod and a movable measurement head arranged at the bottom of the connection plate. The inner diameters of a large scale of workpiece holes can be conveniently measured through the hole diameter measuring tool, and the measurement precision is high.
Description
Technical field
The present invention relates to measurement mechanism technical field, particularly relate to aperture measurer.
Background technology
The internal diameter in current measuring workpieces hole generally adopts vernier caliper, but vernier caliper measurement process is comparatively complicated, when measuring workpiece in enormous quantities, and often bothersome effort; Adopt the internal diameter of vernier caliper measurement workpiece hole, can not carry out the fine setting of size, measuring accuracy is not high.
Summary of the invention
The object of this invention is to provide one to be convenient to measure workpiece hole internal diameter in enormous quantities, and the aperture measurer that measuring accuracy is high.
Technical scheme of the present invention is as follows:
Aperture measurer, comprises dial gauge, and described dial gauge central authorities are provided with fixation measuring assembly, and left end is provided with movable measurement components; Described movable measurement components comprises the web joint be arranged between dial gauge gauge head and dial gauge measuring staff, and is arranged on the movable gauge head bottom web joint.
Described movable gauge head bottom is spherical.Because movable gauge head bottom adopts spherical, can fit tightr with measured surface, make measurement more accurate.
Described fixation measuring assembly comprises " L " shape fixed head be arranged on below dial gauge; With " L " shape fixed head with the use of arch-shaped pressing plate, and be arranged on the fixing gauge head of " L " shape fixed head bottom." L " shape fixed head and arch-shaped pressing plate clamp with the use of by dial gauge, and " L " shape fixed head is connected more firm, when avoiding measuring, the rotation of dial gauge, causes measuring error.
Described fixing gauge head bottom is spherical.Because fixing gauge head bottom adopts spherical, can fit tightr with measured surface, make measurement more accurate.
The invention has the beneficial effects as follows: the present invention is respectively equipped with fixation measuring assembly and movable measurement components on dial gauge, the fixing gauge head on fixation measuring assembly and tested surface are fitted, as measuring basis; Movable measurement components regulates the position between fixation measuring assembly and another tested surface to fit, because movable gauge head is connected between dial gauge gauge head and measuring staff, when movable gauge head regulates and fix the distance between gauge head, the minute movement amount produced will be shown by dial gauge pointer, thus draw the size in measured workpiece aperture.
Accompanying drawing explanation
By the detailed description below in conjunction with accompanying drawing, aforesaid and other object, the feature and advantage of the present invention will become apparent.
Wherein: Fig. 1 is structural representation of the present invention;
Fig. 2 is A-A cut-open view of the present invention;
In accompanying drawing, 1 is dial gauge, and 2 is dial gauge gauge head, and 3 is dial gauge measuring staff, 4 is web joint, and 5 is movable gauge head, and 6 is " L " shape fixed head, and 7 is arch-shaped pressing plate, 8 is fixing gauge head, and 9 be the line fixing gauge head and spherical center, movable gauge head bottom, and 10 is the axis of dial gauge measuring staff.
Embodiment
embodiment 1
Shown in Fig. 1-Fig. 2, aperture measurer, comprises dial gauge 1, and described dial gauge central authorities are provided with fixation measuring assembly, and left end is provided with movable measurement components; Described movable measurement components comprises the web joint 4 be arranged between dial gauge gauge head 2 and dial gauge measuring staff 3, and is arranged on the movable gauge head 5 bottom web joint; This movable gauge head bottom is spherical.Described fixation measuring assembly comprises " L " shape fixed head 6 be arranged on below dial gauge; With " L " shape fixed head with the use of arch-shaped pressing plate 7, and be arranged on the fixing gauge head 8 of " L " shape fixed head bottom; This fixing gauge head bottom is spherical.
Before measurement, first with ring standard gauge or outside micrometer to after zero, measure by relative method.
During measurement, the spheric probe of fixing gauge head is adjacent on hole wall, and the minute movement amount of movable gauge head is read by the pointer of dial gauge.
Preferably, described " L " shape fixed head 6 is connected by the bolt of arch-shaped pressing plate both sides with between arch-shaped pressing plate 7, and adopting removably connects is convenient to keep in repair and change the part worn and torn; With bolts, dial gauge can be clamped, prevent it from rotating.
Preferably, described fixing gauge head 8 is connected on " L " shape fixed head by the first screw.Adopting removably connects is convenient to keep in repair and change the part worn and torn.
Preferably, described movable gauge head 5 is connected on web joint by the second screw.Adopting removably connects is convenient to keep in repair and change the part worn and torn.
Embodiment 2
On the basis of aforementioned schemes, in order to make measuring accuracy higher; Preferably, the line 9 at the spherical center of described fixing gauge head and movable gauge head bottom is parallel to the axis 10 of dial gauge measuring staff.
The present invention is not limited to described embodiment, and those skilled in the art, not departing from spirit of the present invention namely openly in scope, still can do some and revise or change, therefore the scope that the scope of the present invention limits with claims is as the criterion.
