Abstract
The invention provides a touching gauge for an in-hole trapezoid groove. The touching gauge for the in-hole trapezoid groove can simply, conveniently and rapidly measure tolerance of the width and tolerance of the depth of an oil groove in a work piece hole, is high in measuring efficiency, guarantees processing quality of the oil groove in the work piece hole, and is characterized by comprising a toughing gauge sleeve. A moving measuring rod is arranged on the touching gauge sleeve. A measuring head in fit with the in-hole trapezoid groove is arranged at one end of the moving measuring rod. The positions, corresponding to the upper end face of the touching gauge sleeve, of two sides of the moving measuring rod are provided with staggered footsteps which are corresponding to the tolerance value of the in-hole trapezoid groove.
Description
Technical field
The present invention relates to measure the technical field of the instruments of inspection, be specially dovetail groove touch rule in a kind of hole.
Background technology
When being provided with oil groove in the workpiece hole, for the fuel feeding that guarantees oil groove normal, the oil groove width has certain tolerance, and owing to oil groove is in the workpiece hole, measurement to its width is very difficult, especially when the hole inner oil sump was dovetail groove, the degree of depth of its oil groove and width tolerance can't be measured, and had also affected the crudy of workpiece hole inner oil sump.
Summary of the invention
For the problems referred to above, the invention provides in a kind of hole dovetail groove and touch rule, can be simply, easily and fast workpiece hole inner oil sump width depth tolerances is measured, it is high to measure efficient, has guaranteed the crudy of workpiece hole inner oil sump.
Its technical scheme is such: dovetail groove touches rule in a kind of hole, it is characterized in that: it comprises touching advises cover, described touch rule put and are provided with movable measuring staff, described movable measuring staff one end is provided with the measuring head that cooperates with dovetail groove in the hole, described movable measuring staff both sides and the described touch rule corresponding position of face, set upper side be provided with the hole in staggered step corresponding to dovetail groove tolerance value.
It is further characterized in that: described touch rule put and are provided with transverse holes, are provided with handle in the described transverse holes, and described handle connects described movable measuring staff, and described transverse holes diameter is greater than described handle diameter.
In the said structure of the present invention, touch to advise to put and be provided with movable measuring staff, movable measuring staff one end is provided with the measuring head that cooperates with dovetail groove in the hole, described movable measuring staff both sides and the described touch rule corresponding position of face, set upper side be provided with the hole in staggered step corresponding to dovetail groove tolerance value, measuring head is put into the hole dovetail groove, submit the faulting of slab ends rank and touch the degree of depth and the width tolerance of advising dovetail groove in the Relative position determination hole that puts end face by movable measuring staff.
Description of drawings
Fig. 1 is the main TV structure figure that dovetail groove touches rule in the hole of the present invention.
Embodiment
See Fig. 1, dovetail groove touches rule in a kind of hole, it comprises that touching rule overlaps 1, touch on the rule cover 1 and be provided with movable measuring staff 2, movable measuring staff 2 one ends are provided with the measuring head 3 that cooperates with dovetail groove in the hole, movable measuring staff 2 both sides and touch advise put end face 4 correspondence positions be provided with the hole in corresponding staggered step 5-1, the 5-2(of dovetail groove tolerance value, touch on the rule cover 1 and be provided with transverse holes 6, be provided with handle 7 in the transverse holes 6, handle 7 connection activity measuring staffs 2, transverse holes 6 diameters are greater than handle 7 diameters.
Illustrate that in conjunction with Fig. 1 dovetail groove touches the fundamental diagram of advising in the hole of the present invention:
In the interior dovetail groove of measuring head 3 patchholes, when being higher than or flushing in to touch to advise, higher step 5-1 puts end face 4, lower step 5-2 is lower than in or flushes in when touching rule and putting end face 4, then the margin tolerance of dovetail groove meets standard in the hole, touch rule and put end face 4 when higher step 5-1 and lower step 5-2 are higher than, then dovetail groove is narrow in the hole, touch rule and put end face 4 when higher step 5-1 and lower step 5-2 are lower than, then dovetail groove is wide in the hole, can be simple, convenient, rapidly workpiece hole inner oil sump width depth tolerances is measured, measurement efficient is high, has guaranteed the crudy of workpiece hole inner oil sump.
Claims (2)
1. dovetail groove touches rule in the hole, it is characterized in that: it comprises touching advises cover, described touch rule put and are provided with movable measuring staff, described movable measuring staff one end is provided with the measuring head that cooperates with dovetail groove in the hole, described movable measuring staff both sides and the described touch rule corresponding position of face, set upper side be provided with the hole in staggered step corresponding to dovetail groove tolerance value.
2. dovetail groove touches rule in a kind of hole according to claim 1, it is characterized in that: described touch rule put and are provided with transverse holes, be provided with handle in the described transverse holes, described handle connects described movable measuring staff, and described transverse holes diameter is greater than described handle diameter.
