Description
Technical field
The present invention relates to a kind of frock that is used for the connecting lever of high-voltage electrical equipment is carried out angular detection.
Background technology
As shown in Figure 1; Often can use a kind of connecting lever 1 in the high-voltage electrical equipment; Connecting lever 1 has spline endoporus 2, is formed with an arc notch 7 along spline endoporus 2, meets at the axle center of spline endoporus 2 after the plane at this place, arc notch 7 both sides of the edge prolongs; The angle of the angle of this two side plane has strict qualification, and general value is 151 ° ± 10 '.
Under normal conditions, the measurement of angle is sat to measure on the mark appearance expensive accurate three and is carried out.Its process is: earlier measure the center of circle according to spline endoporus 2---be true origin, respectively look for 2 points then on two planes, automatic connecting is calculated the angle error on two planes, and the error of two plane point of intersection and initial point is judged the qualification of part in view of the above.
Said method has following shortcoming: 1, accurate three sit costing an arm and a leg of measurement mark appearance, environment for use requires high; 2, can not detect in a large number; 3, the shape of connecting lever 1 is complicated, is difficult for during measurement placing; 4, spline endoporus 2 has deviation with the spline tooth reference circle, and in part movement, is the axle center with the spline tooth reference circle; 5, can not represent the plane at 2.
Above-mentioned shortcoming finally can cause detecting qualified part and in mechanical motion, not reach designing requirement.
Summary of the invention
The purpose of this invention is to provide a kind of can accurately the measurement, and be suitable for the detection frock of large scale measurement the angle of connecting lever.
In order to achieve the above object, technical scheme of the present invention has provided a kind of connecting lever angular detection frock, it is characterized in that; Comprise that the middle part has the splined shaft of spline tooth, splined shaft is inserted in the spline endoporus of connecting lever to be measured, and the two ends of splined shaft are located at outside the connecting lever to be measured; The spline tooth at splined shaft middle part and the spline tooth of spline endoporus are meshing with each other; Detection with endoporus is enclosed within support member outside the end of splined shaft, between the end of endoporus and splined shaft, fills in rotation axis, and this detection is with being formed with a protruding cambered surface on the support member; After prolonging, the plane at the place, both sides of the edge of protruding cambered surface meets at the axle center of endoporus; The angle on the plane at this place, both sides of the edge and suitable with the angle of the actual support member raising cambered surface that matches of connecting lever to be measured, this convexity cambered surface snaps in the arc notch of connecting lever to be measured, and the plane with arc notch homonymy edge is close on the plane at a lateral edges place of protruding cambered surface; Form an arc-shaped gaps between the plane of the opposite side edge of protruding cambered surface and the plane of arc notch homonymy edge; In this arc-shaped gaps, be provided with arc and detect piece, under the qualified situation of connecting lever to be measured, this arc detects piece and can just in time this arc-shaped gaps be filled up.
After adopting a kind of connecting lever angular detection frock provided by the invention; Whether the processing that can must detect the connecting lever angle rapidly is qualified, thereby enhance productivity, and makes product quality controlled in time in manufacture process; Its cost is lower, is fit to large scale measurement.

Embodiment
For making the present invention more obviously understandable, now with a preferred embodiment, and conjunction with figs. elaborates as follows.
Before the frock that design detects the angle of connecting lever as shown in Figure 11, we analyze the actual operating position of connecting lever 1.After the analysis, finding why the angle of connecting lever 1 has strict qualification, is that this support member has an arc convex face because connecting lever 1 need be used with a kind of support member, and the arc notch 7 of this arc convex face and connecting lever 1 is used.If the angle of arc convex face is 147.5 ° ± 10 ', angle is 151 ° ± 10 ', then both have one to make connecting lever 1 that one 360 °-151 °-147.5 °=61.5 ° the anglec of rotation arranged after cooperating.When using, support member is motionless, and connecting lever 1 rotates in 0 °-61.5 ° scope, rotates thereby drive miscellaneous part.Therefore, the purpose of assurance angle is actually in order to guarantee that connecting lever 1 can rotate in 0 °-61.5 ° scope.
Based on above-mentioned analysis; We have designed like Fig. 2 to connecting lever angular detection frock shown in Figure 6; This frock comprises that the middle part has the splined shaft 3 of spline tooth, and splined shaft 3 is inserted in the spline endoporus 2 of connecting lever 1 to be measured, and the two ends of splined shaft 3 are located at outside the connecting lever 1 to be measured; The spline tooth at splined shaft 3 middle parts and the spline tooth of spline endoporus 2 are meshing with each other, and the detection with endoporus 6 is enclosed within outside the end of splined shaft 3 with support member 4.This detects with support member 4 and makes according to the design size of the support member of reality is strict.Between the end of endoporus 6 and splined shaft 3, fill in rotation axis 5; This detection is with being formed with a protruding cambered surface 8 on the support member 4; After prolonging, the plane at the place, both sides of the edge of protruding cambered surface 8 meets at the axle center of endoporus 6; The angle β on the plane at this place, both sides of the edge and suitable with the angle of the connecting lever 1 actual support member raising cambered surface that matches to be measured; This convexity cambered surface 8 snaps in the arc notch 7 of connecting lever 1 to be measured, and the plane with arc notch 7 homonymy edges is close on the plane at a lateral edges place of protruding cambered surface 8, forms an arc-shaped gaps between the plane of the plane of the opposite side edge of protruding cambered surface 8 and arc notch 7 homonymy edges; In this arc-shaped gaps, be provided with arc and detect piece 9, this arc detects the angle γ=angle-angle β of piece 9.
Under the qualified situation of connecting lever to be measured 1, this arc detects piece 9 and can just in time this arc-shaped gaps be filled up.If the angle of connecting lever 1 to be measured is bigger than normal, after then arc being detected piece 9 and fills in, arc detect piece 9 can in contract, if the angle of connecting lever 1 to be measured is less than normal, after then arc being detected piece 9 and fills in, arc detects piece 9 can be outstanding.Thus, can very conveniently must judge whether the angle of connecting lever 1 to be measured is qualified.
