Abstract
The present invention relates to a ball type bore dial indicator. The ball type bore dial indicator comprises a dial indicator, a locking device and a handle; the ball type bore dial indicator further comprises a hollow measuring rod; the handle is connected with the dial indicator through the locking device; the handle is fixed to the measuring rod through a bolt; a pushing rod is installed in the cavity of the measuring rod; and the measuring rod is provided with ball measuring heads which abut against one end of the pushing rod, the other end of the pushing rod abuts against the measurement rod of the dial indicator, and therefore, a movement chain can be formed. According to the ball type bore dial indicator of the invention, the pushing rod which abuts against the ball measuring heads and the measurement rod of the dial indicator is adopted; in detection, the balls are squeezed, so as to drive the pushing rod to move vertically, so that the pointer of the dial indicator can be driven to rotate; and the lower end surface of the measuring rod is provided with a reference surface, and therefore, detection can be simple and convenient, and adjustment is not required, and measurement accuracy can be ensured. The ball type bore dial indicator is reasonable in design and is suitable for large-scale popularization.
Description
Technical field
The present invention relates to a kind of dial bore gage, particularly relate to a kind of steel-ball type dial bore gage.
Background technology
Needing strictly to be controlled Product Precision in a lot of manufacture field, this is accomplished by pin
The cubing of property is carried out accuracy detection.Wherein during detection product internal diameter size, need to use internal diameter
Dial gauge.Dial bore gage is interior amount lever measurement bay and the combination of dial gauge, by side head
Straight-line displacement is changed into the angular displacement of dial gauge pointer, and is carried out the inside dimension of reading by dial gauge
Measuring appliance.In order to measure or to check the endoporus of part, deep hole diameter and form accuracy thereof.In
The internal structure of footpath dial gauge measurement bay, including three-way pipe, this three-way pipe one end installation activity is surveyed
Amount head, the other end installs interchangeable measurement head, in vertical mouth of pipe one end, by connecting rod equipped with percentage
Table.During measurement, by the displacement of movable gauge head, drive rotating lever to turn round, thus carry
Dynamic motion bar moves up, and promotes the measurement bar of dial gauge to move, makes dial gauge pointer produce back
Turn.By comparative measurement method, obtain required survey measurements.Making at such dial bore gage
During with, during owing to measuring, movable gauge head all directly contacts with inwall to be measured with test probe replaceable,
And produce rigid friction between inwall, be easily caused bore area and scratch, and then affect product coarse
Rugosity and fineness.Meanwhile, there is certain interval in interchangeable measurement head, can affect survey when mounted
Accuracy of measurement；And after repeatedly changing, easily wearing and tearing in the contact of reversing arrangement, makes measuring result error
Increase.It addition, during Shi Yonging, measurement head can be put into and treat gaging hole, finely tune its position,
Being at the interior diameter of hole, owing to the process adjusted is loaded down with trivial details, its measured value easily produces error.
Summary of the invention
For the present situation of above-mentioned prior art, the technical problem to be solved is to provide
A kind of accuracy of detection that improves, minimizing surface abrasion and the steel-ball type internal diameter percentage of simplification detection process
Table.
The present invention solves the technical scheme that the problems referred to above are used: steel-ball type dial bore gage,
Including dial gauge, locking device and handle, also include the gauge rod of hollow, described handle and percentage
Table is connected by locking device, and described handle is bolted with gauge rod, described gauge rod inner chamber
Being provided with push rod, described gauge rod is provided with the steel ball offseted with described push rod one end and measures head, described
The push rod other end offsets with the measurement bar of described dial gauge, to constitute kinematic chain.
Further, the end face that described push rod and steel ball measurement head offset is provided with chamfering, it is simple to
Steel ball is measured head and is squeezed inward displacement.
Further, described gauge rod lower surface is provided with datum level, during use directly by datum level with
Treating the upper surface laminating of gaging hole, steel ball is measured head and is measurement cross section.
Compared with prior art, it is an advantage of the current invention that: the present invention uses setting to survey with steel ball
The push rod that the measurement bar of amount head and dial gauge offsets, during detection, by extruding steel ball, drives top
The vertical displacement of bar, and then drive the pointer of dial gauge to produce revolution.Meanwhile, use at gauge rod
Lower surface arranges datum level, detection simplicity, it is not necessary to adjust, and ensure that certainty of measurement.This
Bright reasonable in design, it is suitable for large-scale promotion.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, to the technical scheme in the embodiment of the present invention
It is clearly and completely described, it is clear that described embodiment is only a present invention part
Embodiment rather than whole embodiments.Based in the present invention being embodiment, this area is general
The every other embodiment that logical technical staff is obtained under not making creative work premise,
Broadly fall into the scope of protection of the invention.
Steel-ball type dial bore gage, including dial gauge 1, locking device 2 and handle 3, also wraps
Including the gauge rod 4 of hollow, described handle 3 is connected by locking device 2 with dial gauge 1, described
Handle 3 is bolted with gauge rod 4, and described gauge rod 4 inner chamber is provided with push rod 41, described
Gauge rod 4 is provided with the steel ball measurement 42 offseted with described push rod 41 one end, described push rod 41
The other end offsets with the measurement bar 11 of described dial gauge 1, to constitute kinematic chain.Described push rod
41 measure 42 end face offseted with steel ball is provided with chamfering 411.Described gauge rod 4 lower surface
It is provided with datum level 31.
During use, according to treating pore size and the degree of depth of gaging hole, select corresponding gauge head.Will amount
Bar 4 stretches in treating gaging hole, makes the datum level 31 of gauge rod 4 lower end recline measured piece upper surface,
So that steel ball measurement 42 is on horizontal cross-section, according to the rule of steel ball measurement 42 on gauge head
Lattice, determine the inner diameter values of measured piece.When measuring, steel ball measurement 42 is entering measured piece
Time steel ball can be promoted to measure 42 inward displacement, and then transmission by from the pressure of inwall
On push rod 41, being changed into the vertical displacement of push rod 41, the measurement bar 11 of dial gauge 1 moves
Dynamic, make dial gauge 1 pointer produce revolution.The measurement that numerical value is the most required is obtained according to commensuration
Value.
Last it is noted that above example is only in order to illustrate technical scheme, and
Non-to its restriction；Although the present invention being described in detail with reference to previous embodiment, ability
Territory it will be appreciated by the skilled person that it still can be to the technical side described in foregoing embodiments
Case is modified, or replaces wherein portion of techniques feature on an equal basis；And these amendment or
Person replaces, and does not make the essence of appropriate technical solution depart from various embodiments of the present invention technical scheme
Spirit and scope.
