Description
Technical field
The utility model relates to a kind of for measuring the threaded hole depth detection apparatus of threaded hole effective thread depth.
Background technique
For the drilling convenient for threaded hole, threaded hole bosom also has one section of taper hole, existing threaded hole depth detection apparatus
Usually the depth in entire hole is detected, rather than the effective of threaded hole is detected using depth, existing threaded hole
The detection numerical error of depth detection apparatus is larger.After the processing for completing workpiece, need effectively to make by detection threaded hole
With depth, to judge whether threaded hole is qualified.
Summary of the invention
The purpose of the utility model is to provide a kind of screw thread hole depths that can accurately detect threaded hole and effectively use depth
Detection device.
To achieve the above objectives, the present invention adopts the following technical solutions: a kind of threaded hole depth detection apparatus, including
Vertically arranged mobile jib, the mobile jib has the locating slot through axial ends, is combined with positioning column in the locating slot, described
It is formed with location hole on mobile jib side wall and is combined with fixed column, fixed column end and location hole inner wall are formed with mutually matched spiral shell
Line structure, the location hole are communicated with locating slot, and the positioning column axial length is greater than mobile jib axial length, the positioning column two
End is always positioned on the outside of locating slot, and the positioning column end is formed with the outer spiral shell matched with the internal thread structure of threaded hole to be measured
Line structure, the mobile jib lower thread are combined with location nut, under the location nut axial face be plane and with positioning axis of a cylinder
Line is vertically arranged.
Carry out the utility model in use, being threadedly engaged positioning column in threaded hole, and positioning column is screwed to most deep
Place until twist it is motionless until, then by main rod strap outside positioning column, and by fixed column realization positioning column and mobile jib fixation, with
Rotational positioning nut is so that location nut axial end face is affixed with the workpiece end face of threaded hole afterwards, subsequent rotational positioning column with
Whole device is removed from workpiece, obtains the distance under positioning column end to location nut between axial face by slide calliper rule, then
Subtracted each other by positioning column length to obtain the length that positioning column is located in threaded hole, to obtain the effective using deep of threaded hole
Degree.It wherein, can be by rotational positioning nut, to realize being adjacent to for location nut and workpiece end face, to realize the effective of threaded hole
It is more accurate using depth detection.
Preferably, cross section outer rim shape, locating slot cross section inner edge shape that the positioning column deviates both ends are in
Regular polygon.The rotation of positioning column is convenient in above-mentioned setting, and the rotation of positioning column can be realized by tools such as spanners.
Preferably, be threadedly engaged locking nut on the mobile jib, the locking nut rotation with location nut axis
It is in contact to face.Above-mentioned setting is to avoid location nut rotation.
The utility model has the advantages that can accurately detect threaded hole effectively uses depth.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of the utility model.
Specific embodiment
The utility model is further described below according to the drawings and specific embodiments.
As shown in Figure 1, a kind of threaded hole depth detection apparatus of the utility model, including vertically arranged mobile jib 1, mobile jib
1 has the locating slot through axial ends, is combined with positioning column 2 in locating slot, is formed with location hole on 1 side wall of mobile jib and cooperates
There is fixed column 3,3 end of fixed column and location hole inner wall are formed with mutually matched helicitic texture, and location hole is communicated with locating slot,
2 axial length of positioning column is greater than 1 axial length of mobile jib, and 2 both ends of positioning column are always positioned on the outside of locating slot, 2 end shape of positioning column
The external thread structure 21 that the internal thread structure of Cheng Youyu threaded hole to be measured matches, 1 lower thread of mobile jib are combined with location nut
4, the lower axial face of location nut 4 is plane and is vertically arranged with 2 axis of positioning column.Wherein, positioning column 2 deviates the cross section at both ends
Outer rim shape, locating slot cross section inner edge shape are in regular polygon；Wherein, it has been threadedly engaged locking nut 5 on mobile jib 1, has locked
The tight rotation of nut 5 with axial face in location nut 4 to be in contact.
Carry out the utility model in use, being threadedly engaged positioning column in threaded hole, positioning column is twisted by spanner
To bosom until twist it is motionless until, then by main rod strap outside positioning column, and positioning column and mobile jib are realized by fixed column
Fixed, subsequent rotational positioning nut is so that location nut axial end face is affixed with the workpiece end face with threaded hole, then rotation
Positioning column whole device to be removed from workpiece, by slide calliper rule obtain under positioning column end to location nut between axial face away from
From then by subtracting each other with positioning column length to obtain the length that positioning column is located in threaded hole, to obtain having for threaded hole
Effect uses depth.
The utility model has the advantages that can accurately detect threaded hole effectively uses depth.
