Description
Technical field
The utility model is related to the detection instrument of the larger diameter internal bore of annular element, and in particular on a kind of workpiece biside plate
Annular element larger diameter internal bore coaxiality detecting tool.
Background technology
Referring to Fig. 1, in some special machine equipment, there is a kind of workpiece 7, be respectively connected with two side plates 73 of the workpiece 7
The equal and annular element 70 with identical larger diameter internal bore 71 of the vertical range of one its bottom to base plate 72.In order to ensure this
Normal use of the workpiece 7 in special machine equipment, it is necessary to assure the axiality of the larger diameter internal bore 71 of two annular element 70,
Size that i.e. must be by the radius value of the larger diameter internal bore 71 of each annular element 70 plus its wall thickness adds its bottom the bottom of to
The height value of the bottom surface of plate 72 controls in rational scope, that is, the larger diameter internal bore 71 of two annular element 70 must be made
Radius value plus its wall thickness size along with its bottom equal to the height value of the bottom surface of base plate 72, i.e., must make two ring-types
The concentricity tolerance value range of the larger diameter internal bore 71 of part 70 controls in the reasonable scope.
For this reason, it may be necessary to after two annular element 70 are connected on the biside plate 73 of workpiece 7, to two annular element 70
The axiality of larger diameter internal bore 71 detected, to determine their axiality whether in rational scope.At present, to two
The axiality of the larger diameter internal bore 71 of annular element 70 is detected that adopted detection instrument is mainly ruler.During detection, point
Not Cai Yong each annular element 70 of ruler direct detection bottom to base plate 72 bottom surface height value, if each annular element
70 bottoms are equal to the height value of the bottom surface of base plate 72, show that the axiality of the larger diameter internal bore 71 of two annular element 70 is public
Difference value range controls in the reasonable scope, and the concentricity tolerance value range of the larger diameter internal bore 71 of otherwise two annular element 70 is just
In the reasonable scope, its problem for existing is not for control；It is to pass through to estimate the inspection on ruler by testing staff in detection process
Whether measured value is controlling to enter in the reasonable scope to the concentricity tolerance value range of the larger diameter internal bore 71 of two annular element 70
Row judges, is affected by eyesight, detection level and ruler precision etc. that detection is not convenient, less efficient enough, and usually causes detection
Not accurate enough, there is error, cause workpiece 7 not reach requirement in use, cause to assemble the special machine equipment of the workpiece 7 not
Can normal work.
For solving above-mentioned technical problem, applicant had applied entitled before the application proposition《A kind of workpiece biside plate
Upper annular part larger diameter internal bore axiality detection device》Utility model patent, shown in Figure 2, the device includes major axis
1st, measurement bar 2, bearing 3 and detection platform 4, the bearing 3 have two, and they can adjust the setting of axial spacing ground and are supported in upwards
In detection platform 4,1 two ends height adjusting degree ground of the major axis is connected with the top of two bearings 3 respectively, the measurement bar
2 is vertical with major axis 1, and its inner can rotate around major axis 1 and can axially slidably be connected on major axis 1 along major axis 1, and its outer end is to length
The length of the axial line of axle 1 and shape equal with the radius value of the larger diameter internal bore of annular element is also corresponding cylindrical arc,
The vertical range of the axial line of the major axis 1 to the upper surface of detection platform 4 and the half of the larger diameter internal bore 71 of annular element 70
Footpath be worth plus annular element 70 wall thickness value along with annular element 70 bottom to workpiece 7 base plate 72 bottom surface height it
With equal.The device can be in accordance with the following steps to workpiece both sides annular element larger diameter internal bore axiality detect；First
First, the base plate 72 of workpiece 7 is positioned in detection platform 4, and so that workpiece 7 is integrally located between two bearings 3；Then, length is made
Axle 1 stretches out in the state outside the outer end of the larger diameter internal bore 71 of both sides annular element 70 in its two ends；Then, along major axis 1
Rotationally, measurement bar 2 is moved axially, moves in the larger diameter internal bore 71 for making first any one annular element 70 backward of measurement bar 2；
The equal and major axis 1 of 71 radius of larger diameter internal bore due to length and the annular element of the axial line of the outer end to major axis 1 of measurement bar 2
The radius value of larger diameter internal bore of vertical range and annular element of upper surface of axial line to detection platform 4 add ring-type zero
The wall thickness value of part is equal along with the height sum of the bottom to workpiece base plate of annular element.Therefore, as long as measurement bar 2 is in major axis
Rotationally axially movably can move within the larger diameter internal bore 71 of each annular element 70 on 1, it is possible to determine work
The axiality of the larger diameter internal bore 71 of 7 both sides annular element 70 of part is in rational scope.Otherwise, as long as measurement bar 2 is being grown
Rotationally axially movably can not move within the larger diameter internal bore 71 of any one annular element 70 on axle 1, so that it may
To determine the axiality of the larger diameter internal bore 71 of 7 both sides annular element 70 of workpiece in irrational scope.Therefore, the device
Detect that more convenient, detection efficiency is higher, detection is relatively more accurate, be not in error, ensure that workpiece 7 reaches in use and want
Ask, and enable the special machine equipment normal work of the assembling workpiece 7.
However, the device is overall structure due to measurement bar 2, the length of measurement bar 2 is changeless, i.e., its outer end is extremely
The length value of the axial line of major axis 1 is changeless.Thus, can only be big to a kind of workpiece biside plate upper annular part of size
The axiality of diameter interior bore is detected that adaptability is poor.Big to various sizes of workpiece biside plate upper annular part when needing
When the axiality of diameter interior bore is detected, it is necessary for redesigning and change measurement bar 2, the design of measurement bar 2, manufacture, more
Change relatively costly.
