Abstract
Provided is a testing apparatus for a screw thread tester of an electronic fitting. The testing apparatus comprises a pedestal and an electric screwdriver disposed on the pedestal. The front end of the main shaft of the electric screwdriver is provided with two clamping slots capable of accommodating two radial projections of a screwdriver head; the clamping slots are provided with a rotation shaft; one end of the rotation shaft is connected with the clamping slots; the other end of the rotation shaft is connected with a fixation sheet disposed on the pedestal; the fixation sheet is provided with a gear; the gear is engaged with the rotation shaft; and the gear is connected with a screw rod disposed on the fixation sheet. The testing apparatus provided by the utility model solves the problems during an implementation process of the aforementioned screw thread tester that the operation is complex, the time consumption is quite large, the labor of workers is greatly consumed, people are shifted every two hours they work for, and mass production of a factory is difficult. The testing apparatus provided by the utility model has the advantages of simple and practical structure, simple operation, convenient maintenance and low cost, thereby having great market popularization value.
Description
Technical field
The utility model relates to electronic components testing apparatus, the proving installation of thread tester for especially a kind of electronic components.
Background technology
On cylinder or conical surface, along the formed continuous projection with regulation tooth form of helix.Projection refers to the entity part of screw thread two sides, claims again tooth.
In machining, screw thread on a columniform axle (or bore area) is cut into cutter or emery wheel, and now workpiece is goed around, and cutter moves axially certain distance along workpiece, and the vestige that cutter cuts out on workpiece is exactly screw thread.The screw thread forming at outer round surface claims external thread.The screw thread forming at bore area claims internal thread.The basis of screw thread is the helix on circular shaft surface.If the section of screw thread is triangle conventionally, be V-thread; Section is the trapezoidal acme thread that is called; Section is that serrate is called saw-tooth thread; Section is the square square thread that is called; Section is that circular arc is called circle-arc screw-thread etc.
Screw thread is divided into triangle thread, square thread, acme thread and saw-tooth thread etc. by its cross sectional shape (tooth form).Wherein triangle thread is mainly used in connecting (seeing thread connection), and rectangle, trapezoidal and saw-tooth thread are mainly used in transmission.Screw thread is distributed in the external thread that cries of parent outside surface, at the internal thread that cries of parent inside surface.The screw thread forming on cylinder parent is straight thread, and the screw thread forming on circular cone parent is tapered tread.Screw thread is divided into left-handed and dextrorotation two kinds by hand of helix, generally use right-hand thread.Screw thread can be divided into single line with multi-thread, connect the single line that mostly is of use; Require when the transmission, into rising fast or efficiency is high, to adopt two-wire or multi-thread, but be generally no more than 4 lines.
Triangle thread is mainly used in connecting, and rectangle, trapezoidal and saw-tooth thread are mainly used in transmission; By hand of helix, be divided into left-hand thread (LHT) and right-hand thread, generally use right-hand thread; By the quantity of helix, be divided into single thread, double thread and multi start thread; What connect use mostly is single line, the employing two-wire that transmission is used or multi-thread; By the size of tooth, be divided into coarse thread and fine thread etc., different with function by use occasion, can be divided into binding thread, pipe thread, motion thread, special screw thread etc.
Straight thread Zhong ﹐ triangle thread self-locking property is good.Its minute coarse thread and the multiplex coarse thread of the general connection of closely-pitched Liang Zhong ﹐.The pitch of closely-pitched is little, and lift angle is little, and self-locking property is better, is usually used in small part thin walled tube, has vibration or the connection of variable load and micromatic setting etc.Pipe thread is for pipe fitting close-coupled.Square thread efficiency is high, but grinds because being difficult for, and internal and external threads to screw centering more difficult, therefore often replaced by acme thread.The working edge of saw-tooth thread tooth approaches rectangle straight flange, is used for bearing unidirectional axial force.
The tooth form of tapered tread is triangle, mainly by the distortion of tooth, guarantees the compactedness of screw thread pair, is used for pipe fitting.
Chinese patent (publication number 2558952) the utility model provides a kind of thread tester, comprises: a pedestal, and by the material of abrasion performance, made, and there is at least one plane; A most threaded hole, are located in this pedestal, and vertical this plane of its screw advancement direction; And most screw thread nominals, be located at respectively contiguous this threaded hole place in this plane.Thread tester of the present utility model, can before using, test out in advance the specification of the screwing elements such as screw and screw, to avoid causing this screw and screw stripped thread or cause the infringement of combined parts when the practical application because specification misfits, and the taxonomic revision of the equipment that can be used for having a large amount of screwing elements screwing element while disassembling.
The thread tester of above-mentioned opening file in implementation process, complicated operation, consuming time larger, and the spirit that extremely consumes staff, every work must be substituted for 2 hours, is unfavorable for the large-scale production of factory.
Summary of the invention
The utility model, in order to solve the technical matters of above-mentioned existence, provides the proving installation of a kind of electronic components with thread tester.
The technical solution of the utility model is achieved in that
The proving installation of thread tester for a kind of electronic components, comprise pedestal and be arranged on the electric screw driver on pedestal, the front end of the main shaft of described electric screw driver have two can two radial protrusions of accommodating driver bit draw-in groove, this draw-in groove is provided with a rotating shaft, described rotating shaft one end is connected with draw-in groove, and the other end is connected with the stator being arranged on pedestal, and described stator is provided with gear, described gear and rotating shaft engagement, described gear is connected with the screw rod being arranged on stator.
Described gear has several.
Described screw rod has some.
Described screw rod is fixedly connected with gear.
The utility model has solved existing thread tester in implementation process, complicated operation, consuming time larger, and the spirit that extremely consumes staff, every work must be substituted for 2 hours, the problem that is unfavorable for the large-scale production of factory, and the utility model is simple and practical, simple to operate, easy to maintenance, cheap, there is great market popularization value.
