The thread detection device has properties of simple structure, convenient operation, high measuring precision and simple principle and can detect inner threads and outer threads; through stretching projections of the detection probe into the threads and making the projections closely cling to the threads, through relative rotation between the detection probe and the detected threads and matching between the threads and the projections, the transmission rod is enabled to do axial movement and swinging; the range finding sensor detects movement information of the transmission rod and swinging distance information of a back end portion, the detected information is processed by the micro processing chip and is then transmitted to external equipment to acquire movement and swinging distances of the transmission rod, so the thread pitch and the screw tooth depth are acquired, and the thread detection device further has an advantage of strong practicality.
Description
Technical field
The utility model belongs to the screw thread detection field of parts, is a kind of thread detecting device specifically.
Background technology
Detect at present pitch and mainly contain two kinds of modes, one is to adopt vernier caliper to measure, and reading is offered an explanation scale by human eye, easily misreads or read untrue, error is large, in addition the error of vernier caliper itself, makes the numerical value that finally records not smart, affects the precision of workpiece, and this detection method labor intensive, detection speed is slow, causes efficiency low, and cost of labor is high; Another kind of mode is to utilize laser equipment to measure under dynamically, causes assay device structures complexity, troublesome poeration, and manufacturing cost is high.
Because the method cost of two kinds of detections is higher, and advantage between the two can not be complementary.Therefore, how can improve accuracy of detection, reduce artificial factor, reduce costs, raise the efficiency, and one of the problem demanding prompt solution that becomes simple to operate.
Summary of the invention
In view of this, the technical problems to be solved in the utility model is the thread parameter pick-up unit that a kind of structure is ingenious, measuring accuracy is high.
In order to solve the problems of the technologies described above, the utility model adopts following scheme to realize: a kind of thread detecting device, comprise housing, for the detecting head engaging with detected screw thread thread, drive link, range finding inductor and micro-chip processor, described drive link is installed in housing, drive link can move axially and swing, the front portion of drive link stretches out along housing, detecting head is installed on drive link front end, the rear portion of drive link is connected with range finding inductor, range finding inductor is connected with micro-chip processor, described micro-chip processor is provided with one for exporting the signal output of detected screw thread thread data.
As improvement of the present utility model, described detecting head has projection and a cylinder of a taper, and projection is positioned at column side wall and higher than column side wall surface, this projection is connected with drive link leading section.
As further improvement of the utility model, described detecting head comprises a cylinder, and projection is installed on column side wall.
As improvement of the present utility model, described range finding inductor is connected with micro-chip processor by transmission line, and range finding inductor is converted to electric signal transmission by drive link axial internal clearance and carries out conversion process to micro-chip processor.
As further improvement of the utility model, be provided with in housing rear end for clamping and the clamping installing handle of stationary housing.
Compared with prior art, the utility model is simple for structure, easy to operate, measuring accuracy is high, principle is simple, can detect internal thread and external thread, by the projection of detecting head being stretched in screw thread and being close to screw thread, by between detecting head and tested screw thread relatively rotate and screw thread moves axially drive link and swings with protruding coordinating, range finding inductor checks that drive link moves the range information swinging with rearward end, and the information of detection after processing, micro-chip processor is transferred in external unit, draw the distance that drive link moves and swings, draw thus thread pitch and the thread degree of depth, practical.
Accompanying drawing explanation
Fig. 1 and Fig. 2 are the one-piece construction schematic diagram of the utility model embodiment.
Fig. 3 is the inner structure schematic diagram of the utility model embodiment.
Embodiment
In order to allow those skilled in the art understand better the technical solution of the utility model, below in conjunction with accompanying drawing, the utility model is further elaborated.
As shown in Figure 1, Figure 2 and shown in Fig. 3, a kind of thread detecting device, comprises housing 1, detecting head 2, drive link 3, range finding inductor 4 and micro-chip processor 5 for engaging with detected screw thread thread.Described drive link 3 is installed in housing 1, can move axially and swing, and the front portion of drive link 3 stretches out along housing 1, and detecting head 2 is installed on drive link 3 front ends.The detecting head 2 that the present embodiment discloses has projection 21 and a cylinder 22 of a taper, and projection is positioned at cylinder 22 sidewalls and higher than cylinder 22 sidewall circumferential surfaces, this projection 21 is connected with drive link 3 leading sections.The rearward end of drive link 3 is connected with range finding inductor 4, and range finding inductor 4 is connected with micro-chip processor 5 by transmission line.Described micro-chip processor 5 is provided with one for exporting the signal output 51 of detected screw thread thread data.Range finding inductor 4 is converted to electric signal transmission by drive link 3 axial internal clearances and wobble deviation amount and carries out conversion process to micro-chip processor 5, export from signal output 51 through micro-chip processor 5 detected screw thread thread data after treatment, be sent to external unit.Detection system by external unit is carried out analyzing and testing to data, draws thread parameter.
For thread detecting device is better carried and handled easily personnel operation, reduce operating personnel's misoperation, device is fixedly secured, be provided with in housing 1 rear end for clamping and the clamping installing handle 6 of stationary housing.
When use, the clamping installing handle 6 of device is fixed on support, determinand is placed on test board.By the projection of detecting head 21 being stretched in screw thread and being close to screw thread, rotation determinand, screw thread guide protrusion 21 moves axially, thereby Traction Drive bar 3 moves axially, range finding inductor 4 checks the range information that drive link 3 moves, and the information of detection is transferred in external unit after micro-chip processor 5 is processed, external unit, according to drive link 3 displacements and number that determinand is turn-taked, draws thread pitch thus.Simultaneously, in the time not rotating measured object, projection 21 is moved axially along screw thread, projection 21 moves between thread top and bottom, thereby projection 21 is moved radially along cylinder 22, and projection 21 drives drive link 3 to swing, and range finding inductor 4 is responded to drive link 3 rear end amplitude of fluctuation information, and the information of detection is transferred in external unit after micro-chip processor 5 is processed, draw thus screw thread screw thread height data.
Above-described embodiment is only wherein specific implementation of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these apparent replacement forms all belong to protection domain of the present utility model.
