Problems solved by technology

At present, in the detection method of spring performance, general-purpose force-applying machinery is generally used, and the relevant length measurement tool is assisted to detect the spring. In this detection method, the measurement accuracy is generally poor, and at the same time, there are also problems in measuring the workpiece. Disadvantages of scattered structure and troublesome use, especially not suitable for general users' needs for spring detection, and the detection needs of the use site

Embodiment Construction

[0009] The support (4) is fixedly connected with the base (1) to form a mouth-shaped structure, the grating scale (10) is fixedly installed on the side of the support (4), and the lead screw (9) is screwed into the top of the support (4). Install the mandrel (2) on the base (1), and install the moving contact bracket (11) of the grating ruler on the pressure plate (3). A joint (7) and a pressure head (3) are respectively fixedly installed at the upper and lower ends of the pressure sensor (6). Take the center hole of the spring (12) as the positioning reference, place the spring (12) on the mandrel (2) above the base (1), and place the spring (12) so that the big mouth of the spring (12) faces the base (1), place the pressure plate (3) on the spring (12), and at the same time, align the mandrel (2) with the center hole of the pressure plate (3), and connect the pressure head ( 5) Place it at the center of the pressure plate (3), connect the moving contact of the grating scale...

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 [0001] The invention relates to a spring detection mechanism, in particular to a novel spring detection mechanism. It belongs to the technical field of measuring tools and equipment. Background technique [0002] The spring can produce a high-strength spring with a huge elastic force with a small deformation, and is used in many occasions and mechanical equipment. The quality of the spring performance will have an important impact on its application effect. At present, in the detection method of spring performance, general-purpose force-applying machinery is generally used, and the relevant length measurement tools are assisted to detect the spring. In this detection method, the measurement accuracy is generally poor, and at the same time, there are also problems in measuring workpieces. The shortcomings of scattered structure and troublesome use are especially unsuitable for the needs of general users for spring detection and the detection needs of the use...
