Abstract
The invention discloses a novel spring detecting mechanism. A support is fixedly connected with a base to form an opening-shaped structural member; a grating scale is fixedly arranged on a lateral surface of the support; and a leading screw is screwed into the top part of the support. A mandrel is arranged on the base, and a grating scale moving contact support is arranged on a pressure plate. A joint and a pressure head are fixedly arranged at an upper end and a lower end of a pressure sensor respectively. A grating scale moving contact is connected with the grating scale moving contact support; a steel ball is put in a concave spherical pit at one end of the joint; the leading screw is screwed to press the steel ball so that the steel ball tightly presses a spring through the joint, the pressure sensor, the pressure head and the pressure plate; the elastic force generated by the spring is displayed by a reading device of the pressure sensor; and because the performance of the spring is determined by the elastic force generated by the spring under certain deformation, the novel spring detecting mechanism can conveniently detect the performance advantages and disadvantages of the spring.
Description
Technical field
The present invention relates to a kind of spring detecting mechanism, particularly a kind of novel spring detecting mechanism.Belong to the survey instrument equipment technical field.
Background technology
Spring can with small distortion promptly can the huge elastic force of output high-strength spring, in many occasions and plant equipment, use.The quality of spring performance can produce significant effects to its effect.At present, in the detection method for the spring performance, the general application of force machinery of general employing, auxiliary dimensional measuring instrument to be correlated with detects spring, and the ubiquity measuring accuracy is relatively poor in this detection method, simultaneously, measuring workpieces also exists the shortcoming that structure is disperseed, used trouble, especially is not suitable for the needs that general user detects spring, and uses on-the-spot detection to need.
Summary of the invention
The objective of the invention is to: a kind of novel spring detecting mechanism is provided, this spring detecting mechanism not only has accuracy of detection height, compact equipment, characteristics easy to use, and be suitable for the requirement of general user, and be convenient to the detection requirement of production scene to spring to the spring performance checking.
Solving the technical scheme that its technical matters adopts is: a kind of novel spring detecting mechanism, and it is made up of base, mandrel, pressing plate, support, pressure head, pressure transducer, joint, steel ball, leading screw, grating chi, grating chi moving contact rack; Described support is a portal structures, and support is fixedlyed connected with base, forms the structural member of openning shape, and at the grating chi of the side of support fixed installation certain parameter value, the top of support produces threaded hole, is screwed into leading screw in the threaded hole.Described base is a square or a circular plate, heart position is made and is portalled therein, mandrel is installed in the hole, described pressing plate is a discoidal part, its center produces through hole, the slightly larger in diameter of through hole is exposed the diameter parts of base plate outside in mandrel, and grating chi moving contact rack is installed on the pressing plate.Described pressure head is a columniform shape, one end produces blind hole, wherein the slightly larger in diameter of blind hole is in the diameter of pressing plate center pit, described joint is a columniform part, produce the hole of concave ball shape at an end of joint, the two ends up and down of described pressure transducer fixedly mount joint and pressure head respectively.
Measuring method of the present invention and principle are: the center pit with spring is a positioning reference, spring is placed in above the mandrel above the base, the big oral area that should make spring when laying spring is towards base, with pressing plate be placed on spring above, simultaneously mandrel with the center pit of pressing plate is aligned, to be placed on the center of pressing plate with the pressure head that sensor is connected as a single entity, the moving contact of grating chi is linked to each other with grating chi moving contact rack, in the hole of an end concave ball shape of joint, put into steel ball, turn leading screw, make leading screw push down steel ball, so, steel ball just passes through joint, pressure transducer, pressure head, the pressing plate holddown spring, the elastic force that is produced of spring shows by the reading device of pressure transducer, and the compression displacement amount shows by the reading device of grating chi.Because the performance of spring is to be determined by the elastic force that spring is produced under certain deflection, so this kind device can detect the performance quality of spring easily.
Beneficial effect: the present invention is owing to adopt the grating chi and the pressure transducer original paper of electromechanical integration, the deflection and the direct reading of elastic force of spring can be come out, this Spring Detecting Unit not only has accuracy of detection height, compact equipment, characteristics easy to use, and be suitable for the requirement of general user, and be convenient to the detection requirement of production scene to spring to the spring performance checking.
