Description
Technical field
The present invention relates to the detection devices of the larger diameter internal bore of annular element, and in particular to a kind of workpiece both side plate upper annular
Part larger diameter internal bore axiality detection device.
Background technique
Referring to Fig. 1, there is a kind of workpiece 7 in some special machine equipment, be respectively connected on two side plates 73 of the workpiece 7
The vertical range of one its bottom end to bottom plate 72 is equal and has the annular element 70 of identical larger diameter internal bore 71.In order to guarantee this
Normal use of the workpiece 7 in special machine equipment, it is necessary to assure the concentricity of the larger diameter internal bore 71 of two annular elements 70,
The radius value of the larger diameter internal bore 71 of each annular element 70 must be added its bottom end bottom of to plus the size of its wall thickness
The height value of the bottom surface of plate 72 is controlled in reasonable range, that is, the larger diameter internal bore 71 of two annular elements 70 must be made
The height value that radius value adds its bottom end to the bottom surface of bottom plate 72 plus the size of its wall thickness is equal, i.e., must make two ring-types
The concentricity tolerance value range control of the larger diameter internal bore 71 of part 70 is in the reasonable scope.
For this reason, it may be necessary to after on the both side plate 73 that two annular elements 70 are connected to workpiece 7, to two annular elements 70
The concentricity of larger diameter internal bore 71 detected, to determine their concentricity whether in reasonable range.Currently, to two
Detection device used by the concentricity of the larger diameter internal bore 71 of annular element 70 is detected is mainly ruler.When detection, point
Not Cai Yong ruler directly detect the height value of bottom surface of the bottom end of each annular element 70 to bottom plate 72, if each annular element
The height value of 70 bottom ends to the bottom surface of bottom plate 72 is equal, shows that the concentricity of the larger diameter internal bore 71 of two annular elements 70 is public
In the reasonable scope, otherwise the concentricity tolerance value range of the larger diameter internal bore 71 of two annular elements 70 is just for the control of poor value range
Do not control in the reasonable scope, the problem is that, it is that the inspection on range estimation ruler is passed through by testing staff in detection process
Measured value come the concentricity tolerance value range of the larger diameter internal bore 71 to two annular elements 70 whether control in the reasonable scope into
Row judgement, is influenced by eyesight, detection level and ruler precision etc., and detection is not convenient enough, efficiency is lower, and usually to detect
It is not accurate enough, there is error, cause workpiece 7 not reach requirement in use, and then the special machine for assembling the workpiece 7 is caused to set
Standby cisco unity malfunction.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of convenience, efficient workpiece both side plate upper annular part major diameter
Coaxiality of inner hole detection device.
In order to solve the above technical problems, the present invention adopts the following technical scheme that；
A kind of workpiece both side plate upper annular part larger diameter internal bore axiality detection device, including long axis, measuring rod, support
And detection platform, it is characterised in that: there are two the supports, erects to be supported in detect upwards to their adjustable axial spacings and put down
On platform, it is connected respectively at the top of two supports to the both ends height adjusting degree of the long axis, the measuring rod and long axis
Vertically, inner end can rotate and can axially slidably be connected on long axis along long axis, the axial line of outer end to long axis around long axis
Length it is equal with the radius value of the larger diameter internal bore of annular element and shape is also corresponding outer circle arc, the axis of the long axis
Heart line is to the radius value of the vertical range of the upper surface of detection platform and the larger diameter internal bore of annular element plus annular element
Wall thickness value is equal to the sum of the height of bottom surface of bottom plate of workpiece along with the bottom end of annular element.
It further, further include be assemblied in two supports respectively top and long axis with making long axis both ends height adjusting degree
Two height regulating mechanisms at both ends.
Further, each height regulating mechanism in described two height regulating mechanisms includes the top for being located at each support
The card slot in portion, the longitudinal screw hole extended downwardly from the bottom of the card slot by support, the radial perforation long axis for being located at long axis one end
Radial screw hole, and be assemblied in the bolt among longitudinal screw hole and radial screw hole and the handle at the top for being connected to the bolt
Hand.
Further, the inner end of the measuring rod is equipped with the connecting hole of the micro- diameter greater than long axis in aperture, the measuring rod
Inner end by the connecting hole can around long axis rotate and can be axially slidably connected on long axis along long axis.
Further, the bottom of described two supports is detachably connected with detection platform.
Further, the bottom of described two supports is threadedly coupled with detection platform.
The present invention includes following beneficial effect；
Due to there are two supports of the present invention, erects to their adjustable axial spacings and be supported in detection platform upwards
On, it is connected respectively at the top of two supports to the both ends height adjusting degree of the long axis, the measuring rod and long axis hang down
Directly, inner end can rotate and can axially slidably be connected on long axis along long axis around long axis, the axial line of outer end to long axis
Length is equal with the radius value of the larger diameter internal bore of annular element and shape is also corresponding outer circle arc, the axle center of the long axis
Line adds the wall of annular element to the radius value of the vertical range of the upper surface of detection platform and the larger diameter internal bore of annular element
Thickness value is equal to the sum of the height of bottom surface of bottom plate of workpiece along with the bottom end of annular element.It therefore, can be according to following step
Suddenly the larger diameter internal bore concentricity of workpiece two sides annular element is detected；Firstly, the bottom plate of workpiece is placed detection platform
On, and it is integrally located at workpiece between two supports；Then, so that long axis is in its both ends and stretch out in the big straight of two sides annular element
State except the outer end of diameter inner hole；Then, along long axis rotationally, axial movement measuring rod, make measuring rod first backward any one
It is moved in the larger diameter internal bore of a annular element；Due to measuring rod outer end to long axis axial line length and annular element
Larger diameter internal bore radius is equal and the vertical range of upper surface of the axial line of long axis to detection platform and annular element it is big straight
The radius value of diameter inner hole plus annular element wall thickness value along with the bottom end of annular element is to the sum of the height of workpiece bottom plate phase
Deng.Therefore, as long as measuring rod is rotatably axially movably moved on long axis in the major diameter of each annular element
Within hole, so that it may determine that the concentricity of the larger diameter internal bore of workpiece two sides annular element is in reasonable range.Otherwise, only
Want measuring rod rotationally can not axially movably be moved on long axis any one annular element larger diameter internal bore it
It is interior, so that it may to determine that the concentricity of the larger diameter internal bore of workpiece two sides annular element is in unreasonable range.Therefore, this hair
Bright detection is more convenient, detection efficiency is higher, detection is relatively more accurate, is not in error, can guarantee that workpiece reaches in use
It is required that and the special machine equipment for assembling the workpiece is enable to work normally.
