Abstract
A simple measurement device for an effective connection depth of a threaded hole is characterized in that a rotary handle is arranged at a top end of the device, a cylindrical connecting rod is vertically connected at a lower part of the rotary handle, an upper part of the connecting rod is a scale mark post with scale values, a lower part of the connecting rod is a bolt bar with threads, an annular calibration disc is configured to surround a zero graduation wherein the scale mark post is jointed with the bolt bar, a cylindrical floating drum which can slide up and down is embedded in the connecting rod, and the calibration disc is positioned inside the floating drum. The simple measurement device has the beneficial effects of flexible operation and high accuracy.
Description
Technical field
The utility model relates to machine-building and measurement, effectively connects degree of depth Simple measurement device more specifically for a kind of threaded hole.
Background technology
At present, the domestic parts that are threaded hole are very applicable, universal, depth survey mode during the parts such as its coupling bolt is generally to realize by the pit gauge of vernier caliper, the data of measuring are depth values of threaded hole, and reach in the parts threaded hole effective standard value while being only the parts such as coupling bolt, therefore there is the defect that degree of accuracy is low in this metering system.
Summary of the invention
The purpose of this utility model is to provide a kind of threaded hole and effectively connects degree of depth Simple measurement device, can overcome the deficiency that measuring accuracy is low, has flexible operation, feature that degree of accuracy is high.
The utility model is realized in the following way: a kind of threaded hole effectively connects degree of depth Simple measurement device, it is characterized in that: there is rotary handle on device top, rotary handle lower vertical is connected with cylindrical connecting rod, connecting rod top is the scale mark post with scale value, bottom is threaded body of bolt, the zero graduation place of scale mark post and body of bolt handing-over, around being connected with circular calibrating plate, is also nested with the tubular floating drum that can slide up and down, the inside of calibrating plate in floating drum on connecting rod.
While measuring operation, rotation rotary handle, the body of bolt of drivening rod bottom is connected to along the thread groove of threaded hole inside surface on the parts that are threaded hole, along with body of bolt deepens continuously in threaded hole, floating drum lower edge is subject to the holder power at the parts top that is threaded hole, and the floating drum upper limb at floating drum top rises as starting point along scale mark post take the zero graduation at calibrating plate place.When body of bolt gos deep into threaded hole, until during the thread groove end, body of bolt can not continue deeply, now, the scale on the scale mark post that floating drum upper limb mark shows is exactly effective connection degree of depth of threaded hole.
The beneficial effects of the utility model are: a kind of threaded hole of the utility model effectively connects degree of depth Simple measurement device, have advantages of that flexible operation, degree of accuracy are high.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is that threaded hole effectively connects degree of depth Simple measurement device structural representation.
Fig. 2 is that threaded hole effectively connects degree of depth Simple measurement device embodiment schematic diagram.
In figure, 1. rotary handle, 2. scale mark post, 3. floating drum, 4. floating drum upper limb, 5. calibrating plate, 6. floating drum lower edge, 7. connecting rod, 8. body of bolt, is 9. threaded the parts in hole, 10. threaded hole, 11. thread grooves.
Embodiment
In embodiment illustrated in fig. 2, rotary handle (1) in rotation diagram 1, the body of bolt (8) of drivening rod (7) bottom is connected to along the thread groove (11) of threaded hole (10) inside surface on the parts (9) that are threaded hole, along with body of bolt (8) deepens continuously in threaded hole (10), floating drum lower edge (6) is subject to being threaded the holder power at parts (9) top in hole, and the zero graduation that the floating drum upper limb (4) at floating drum (3) top is located take calibrating plate (5) rises as starting point along scale mark post (2).When body of bolt (8) gos deep into threaded hole (10), until during thread groove (11) end, body of bolt (8) can not continue deeply, and now, the scale on the scale mark post (2) that floating drum upper limb (4) mark shows is exactly effective connection degree of depth of threaded hole (10).
Claims (1)
