Abstract
The invention relates to the technical field of workpiece detecting devices, in particular to a small hole chamfering depth measuring device. A measuring body is arranged, and a step hole is formed in the measuring body. A dial indicator is arranged at the top end of the measuring body, and a locking screw fastening the dial indicator is arranged on the side face of the upper portion of the measuring body. A pressure spring is arranged at the bottom end of the dial indicator in a sleeving mode. The step hole of the measuring body is internally provided with a sliding measuring column making contact with the side end of the bottom of the dial indicator, and a steel ball extending out of the measuring body is arranged at the lower end of the measuring column. The chamfering depth of a workpiece can be rapidly detected.
Description
Technical field
The present invention relates to Workpiece detecting device technical field, particularly relate to aperture depth of chamfering measurement mechanism.
Background technology
The diameter accuracy of the depth of chamfering on the workpiece that some is important and chamfering rear end face requires higher, therefore must carry out the quick detection of inter process; But can not detect the measurer of the depth of chamfering on workpiece at present fast.
Summary of the invention
The object of this invention is to provide a kind of aperture depth of chamfering measurement mechanism of the depth of chamfering that can detect fast on workpiece.
Technical scheme of the present invention is as follows:
Aperture depth of chamfering measurement mechanism, comprises measurement body, is provided with stepped hole in this measurement body; Described measurement body top is provided with dial gauge, and described measurement body upper side is provided with the lock-screw of fastening dial gauge; Described dial gauge bottom is arranged with pressure spring; Be provided with in described measurement body stepped hole and slidably survey post, this survey post contacts with dial gauge bottom portion side end, and lateral column lower end is provided with the steel ball stretching out and measure body.
In described measurement body stepped hole, the surface of revolution is provided with annular groove; The outer surface of revolution of described survey post is provided with kidney slot, is provided with elastic circular ring in this kidney slot.Opened by elastic circular ring and snap in semicircle shape annular groove, thus reaching the restriction to surveying post displacement.
The invention has the beneficial effects as follows: slidably survey capital end and contact with dial gauge by being arranged on to measure in body, bottom connection steel ball; When inserting in workpiece taper hole by body will be measured, survey post displacement and the numerical value of dial gauge changed indirectly draw the diameter of taper hole end face.
Accompanying drawing explanation
By the detailed description below in conjunction with accompanying drawing, aforesaid and other object, the feature and advantage of the present invention will become apparent.
Wherein: Fig. 1 is the first embodiment structural representation of the present invention;
Fig. 2 is the second embodiment structural representation of the present invention;
Fig. 3 is standard component structural representation of the present invention;
In accompanying drawing, 1 for measuring body, and 2 is stepped hole, and 3 is dial gauge, and 4 is lock-screw, and 5 is pressure spring, and 6 for surveying post, and 7 is steel ball, and 8 is annular groove, and 9 is kidney slot, and 10 is elastic circular ring, and 11 is workpiece, and 12 is standard component.
Embodiment
The first embodiment of the present invention, shown in Figure 1, aperture depth of chamfering measurement mechanism, comprises and measures body 1, be provided with stepped hole 2 in this measurement body 1; Described measurement body top is provided with dial gauge 3, and described measurement body 1 upper side is provided with the lock-screw 4 of fastening dial gauge 3; Described dial gauge 3 bottom is arranged with pressure spring 5; Be provided with in described measurement body stepped hole 2 and slidably survey post 6, this survey post 6 contacts with dial gauge 3 bottom portion side end, and lateral column lower end is welded with the steel ball 7 stretching out and measure body.
During measurement, first measurement mechanism is proofreaded on (as shown in Figure 2) standard component 12; Body 1 is measured again with holding, the steel ball 7 (now steel ball is equivalent to side head) of bottom is inserted workpiece 11 taper hole and the upper plane of its bottom surface and measured workpiece is fitted, now survey post and produce corresponding axial displacement by according to the depth of tested chamfered bore, and shown by dial gauge, the value of dial gauge display is the deviate relative to ratings.
Can slide in stepped hole 2 at measurement body owing to surveying post, cannot the displacement of surveying post be limited, for the problems referred to above, the second embodiment of the present invention, shown in Figure 2, in described measurement body 1 stepped hole 2, the surface of revolution is provided with semicircle shape annular groove 8; The outer surface of revolution of described survey post is provided with kidney slot 9, is provided with elastic circular ring 10 in this kidney slot 9.Make, when survey post being pushed in measurement body stepped hole 2, the elastic circular ring in kidney slot 9 opened and snaps in semicircle shape annular groove, thus reaching spacing object.
