According to the digital display thread depth gauge, the surface of the handle is provided with the digital display device for displaying liquid crystal reading, the digital display device is easy for reading, detection on thread holes in multiple specifications can be realized, the use scope is wide, and the digital display thread depth gauge further has properties of precise reading, small error and good flexibility.
Description
Technical field
The present invention relates to a kind of gauge, a kind of digital display depth of thread rule detecting the threaded hole degree of depth, belong to and measure inspection technology field specifically.
Background technology
Along with social development, the quality requirements of client to product improves further, and the size as some significant points threaded holes needs online 100% to detect.Current production line double thread hole depth detect be typically employed in plug thread gauge go side on process some size grooves to carry out qualitative detection, because screw thread drift needs to be screwed into bottom, often because of vision or the sense of touch judgement of size groove position influence operating personnel, cause personal error, be with size groove plug thread gauge can only specially hole be special simultaneously, flexible poor.
Summary of the invention
The object of the invention is to overcome above-mentioned weak point, thus provide a kind of structure simple, compact, rational digital display depth of thread rule, the energy quantitative measurment depth of thread, and the detection of many specifications can be realized, its convenient reading, simple to operate.
According to technical scheme provided by the invention, a kind of digital display depth of thread rule comprise screw thread go side, size cover, handle, digital display device, guiding mandrel and screw thread not-go-end, it is characterized in that: in handle, be provided with guiding mandrel, guiding mandrel is provided with the second locating piece, and the second locating piece can realize the positioning supports to handle; Guiding mandrel is slidably connected size cover, and size cover is clearance fit with guiding mandrel; Guiding mandrel is provided with the first locating piece, pocketed springs on guiding mandrel, the rear end of spring and the first locating piece support and connection, and the front end of spring and size overlap rear end face support and connection; The connecting thread go side, front end of guiding mandrel, rear end connecting thread not-go-end; Described handle surfaces is provided with digital display device.
Further, handle side connects lock-screw, and size cover and handle locking can be fixed by lock-screw.
Compared with the prior art the present invention has the following advantages:
Structure of the present invention is simple, compact, reasonable, simple to operate, and handle surfaces is provided with lock-screw, during inconvenient reading, is locked by lock-screw, then digital display depth of thread rule is screwed out reading again; Handle surfaces is provided with digital display device, and liquid crystal readout shows, and is easy to reading; Can realize the detection of plurality of specifications threaded hole, usable range is extensive; Reading is accurate, and error is little, flexible.
Accompanying drawing explanation
Fig. 1 is front view of the present invention.
Description of reference numerals: 1-screw thread go side, 2-size cover, 3-handle, 4-lock-screw, 5-digital display device, 6-first locating piece, 7-spring, 8-lead mandrel, 9-screw thread not-go-end, 10-second locating piece.
Embodiment
Embodiment in is by reference to the accompanying drawings further described by the present invention below:
As shown in Figure 1, the present invention mainly comprises screw thread go side 1, size cover 2, handle 3, digital display device 5, guiding mandrel 8 and screw thread not-go-end 9, be provided with guiding mandrel 8 in handle 3, guiding mandrel 8 is provided with the positioning supports that the second locating piece 10, second locating piece 10 can realize handle 3.
Size that guiding mandrel 8 is slidably connected cover 2, size cover 2 is clearance fit with guiding mandrel 8.Guiding mandrel 8 is provided with the first locating piece 6, and pocketed springs 7 on guiding mandrel 8, the rear end of spring 7 and the first locating piece 6 support and connection, the front end of spring and size overlap 2 rear end face support and connection.Spring 7 can overlap 2 for size and be close to measured threaded hole end face and provide precompression.
The connecting thread go side, front end 1 of guiding mandrel 8, rear end connecting thread not-go-end 9.When screw thread go side 1 can screw in bottom measured threaded hole smoothly, the change in location of then overlapping 2 end face opposite thread go sides 1 by size measures the degree of depth of threaded hole.
Described handle 3 side connects lock-screw 4, lock-screw 4 size can be overlapped 2 and handle 3 be locked.When detecting, inconvenience reading, can lock lock-screw 4, then screw thread go side 1 be screwed out reading again.
Described handle 3 surface is provided with digital display device 5, and digital display device 5 is Purchased Item, and principle of work is identical with the digital display device on electronic digital indicator, pass through capacitor grid transducer, utilize the coupling scheme of electric capacity that mechanical displacement is transformed into electric signal, intuitively show, facilitate testing staff to carry out reading.
Principle of work of the present invention is: in use, is screwed in screw thread go side in tested threaded hole, to screw thread go side can not screw in again.Tested threaded hole end face is close under the action of the spring by size cover, and now the display reading of digital display device is threaded hole significant depth.During as detected inconvenient reading, lock-screw being locked, then screw thread go side is screwed out reading again.Screw thread go side and screw thread not-go-end are with the use of the screw thread detecting threaded hole, and screw thread go side can screw in threaded hole, screw thread not-go-end can not screw in, then the screw thread of threaded hole is qualified, otherwise then defective.
