Description
Technical field
The utility model relates to a kind of detecting instrument, more particularly, relates in particular to a kind of instrument for detection of the bolt clipper cutting performance.
Background technology
The hardware & tools that China produces, account for the total production advantage in the world, and product is compared with European Union, the U.S., Japan and other countries, scientific and technological content is low, and quality scale is low, and reason is to lack digital checkout equipment, the deviser does not have enough parameters as design considerations, and product quality is difficult to detect and control.
The utility model content
The purpose of this utility model is in order to solve the problem of above-mentioned existence, and a kind of digital checkout equipment is provided, for the deviser provides relevant parameter as design considerations.
The utility model is achieved through the following technical solutions.
the utility model is a kind of instrument for detection of the bolt clipper cutting performance, include fuselage, drive motor, Control System of Microcomputer and shearing performance test mechanism, drive motor and Control System of Microcomputer are electrically connected to, described shearing performance test mechanism includes screw mandrel, nut and strength sensor, screw mandrel is connected with drive motor, the epimere of screw mandrel and hypomere are processed into the screw thread that rotation direction is opposite, the epimere of screw mandrel and hypomere are respectively installed with a nut, at two nut opposing end surfaces, wherein on an end face, strength sensor is installed, strength sensor is connected with microcomputer by data line.
The end that above-mentioned strength sensor contacts with clamp handle installs the clamping plate with detent additional.
The utility model has the advantage of, the employing microcomputer is controlled, can precisely control the rotating speed of drive motor, utilize screw nut driving mechanism to apply test force, in the transmission link of power, strength sensor is installed, can detect by the requirement of standard QB/T2206 " bolt clipper " cutting performance of bolt clipper, for the deviser provides relevant parameter as design considerations.
The accompanying drawing explanation
Fig. 1 is one-piece construction schematic diagram of the present utility model.
Fig. 2 is the structural representation of the utility model shearing performance test mechanism.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
as shown in Figure 1, the utility model is a kind of instrument for detection of bolt clipper 5 cutting performances, include fuselage 7, drive motor 6, Control System of Microcomputer 8 and shearing performance test mechanism, drive motor 6 and Control System of Microcomputer 8 are electrically connected to, described shearing performance test mechanism includes screw mandrel 1, nut 2 and strength sensor 3, screw mandrel 1 is connected with drive motor 6, the epimere of screw mandrel 1 and hypomere are processed into the screw thread that rotation direction is opposite, the epimere of screw mandrel 1 and hypomere are respectively installed with a nut 2, on a wherein end face of two nut 2 opposing end surfaces, strength sensor 3 is installed, strength sensor 3 is connected with Control System of Microcomputer 8 by data line.
The utility model adopts microcomputer to control, can precisely control the rotating speed of drive motor 6, utilize screw nut driving mechanism to apply test force, strength sensor 3 is installed in the transmission link of power, can detect by the requirement of standard QB/T2206 " bolt clipper " cutting performance of bolt clipper 5, for the deviser provides relevant parameter as design considerations.
In the present embodiment, on two nut 2 opposing end surfaces, all be provided with detent, be used to preventing from being clipped in the displacement of skidding of clamp handle between them, an end that contacts with clamp handle in strength sensor 3 installs the clamping plate with detent 4 additional, and is convenient that the clamp handle folder is firm.
principle of work of the present utility model is, first rotary screw rod 1 is adjusted the relative position of two nuts 2, in the middle of the clamp handle of bolt clipper 5 is clamped in, test material is placed between two pincers swords of bolt clipper 5, then by Control System of Microcomputer 8, control drive motor 6 and clockwise rotate screw mandrel 1 with certain rotating speed, at this moment two nuts 2 are opposite because of rotation direction, they are mutually near clamp handle is applied to acting force, make bolt clipper 5 shear the test material of appointment, the change curve of pressure indicating value will pass to Control System of Microcomputer 8 records by strength sensor 3, until test material is cut off, stop reinforcing, then shed load, test completes.
Although describe the utility model in detail with reference to top embodiment, but it will be apparent to one skilled in the art that by the disclosure, and in the situation that do not break away from principle of the present utility model and the spiritual scope that described claim limits, can make a variety of changes or revise the utility model.Therefore, the detailed description of disclosure embodiment only is used for explaining, rather than is used for limiting the utility model, but is defined by the subject-matter of the claims the scope of protection.
