Description
Description Spring Tester Technical Field of the Invention The present invention relates to a spring tester which tests the length of a spring under a certain pressure, exactly the coefficient of elasticity of a spring. Background of the invention A camera rigidity tester (Patent No. CN87215484) employs a pure mechanical structure: by using the dynamic effect of a force, a gravity generated by weights, the mass of which has been known, at a known gravity field is applied onto a spring to be tested; and the deformation quantity of the spring is displayed by a pointer, a dial pair/vernier and a scale pair; and the rigidity of a miniature torsional spring or a miniature tension spring may be calculated according to formulae. The technical solution mentioned above is mainly used for the test of a miniature spring, and has the defects that the structure is complicated and it is inconvenient to take out or put in a spring to be tested, i.e., inconvenient for operating, and so forth. Summary of the Invention To solve the problems of the existing spring testers in the prior art that the structure is complicated and it is inconvenient to take out or put in a spring to be tested, i.e., inconvenient for operating, and so forth, the present invention provides a spring tester with characteristics of simple structure, convenience for taking or putting a spring to be tested, i.e., convenience for operating, and so forth. The technical object of the present invention mentioned above is solved 1 mainly by the following technical solutions. A spring tester is provided, a supporting plate being fixedly provided on a pedestal, a pressing plate being provided above the supporting plate, and the supporting plate being associated with a tension weight; a vernier is provided on one side of the pressing plate, and a scaleplate is provided beside the vernier; a connecting rod fixed with the pressing plate is provided above the pressing plate, and a sliding rack is provided on the connecting rod; a cylinder is provided below the sliding rack; and the cylinder can push the sliding rack to drive the connecting rod and the pressing plate to slide up and down on the pedestal. When testing a spring, the sliding rack is pushed by a cylinder mandril to drive the pressing plate to move up; a spring to be tested is put on the supporting plate, and the cylinder mandril retracts; the pressing plate presses the spring to be tested under the effect of the tension weight; and the vernier on the pressing plate points to a certain reading of the scaleplate, so that the length of the spring to be tested under a certain pressure may be read from the scaleplate. The applied force of the pressing plate may be adjusted by changing the weight. At the end of testing, the sliding rack is pushed by the cylinder to drive the pressing plate to move up, thereby leaving the spring free; and then the spring may be taken out. During the whole process, it is very convenient to take out or put in a spring. That is, it is very convenient for the whole operating process. Preferably, the connecting rod is connected to a stand rack on the pedestal in a sheathed manner. The connecting rod and the stand rack may slide in the axial direction. As the connecting rod is connected to the stand rack on the pedestal in a sheathed manner, the pressing plate and the pedestal may move up and down. Preferably, a cylinder soleplate is provided above the pressing plate. The lower end of the cylinder is disposed on the cylinder soleplate and connected onto a gas guide tube, while the mandril of the cylinder is directed to the 2 sliding rack, wherein the gas guide tube is connected to a gas pump. The telescopic action of the cylinder mandril may be controlled by controlling the operation of the gas pump. Therefore, the present invention features simple structure, reasonable design, convenient operation and so forth. Brief Description of the Drawing Fig. 1 is a structure diagram of the present invention; and Fig. 2 is a side view of Fig. 1. Detailed Description of the Invention The technical solution of the present invention will be further described by embodiment as below with reference to the accompanying drawings. Embodiment 1: As shown in Fig. 1 and Fig. 2, a supporting plate 9, which is disposed horizontally, is fixedly provided on a pedestal 5, a pressing plate 11 is provided above the supporting plate 9, and the supporting plate 9 is associated with a tension weight 13. A vernier 12 is provided on one side of the pressing plate 11, and a scaleplate 3 is provided beside the vernier 12. A connecting rod 6 fixed with the pressing plate 11 is provided above the pressing plate 11, and a sliding rack 1 is provided on the connecting rod. A cylinder 2 is provided below the sliding rack 1. The cylinder can push the sliding rack 1 to drive the connecting rod 6 and the pressing plate 11 to slide up and down on the pedestal 5. The connecting rod 6 is connected to a stand rack on the pedestal 5 in a sheathed manner, and the connecting rod 6 and the stand rack can slide in the axial direction. A cylinder soleplate 8 is provided above the pressing plate 11. The lower end of the cylinder 2 is disposed on the cylinder soleplate 8 and connected onto a gas guide tube 7, while the mandril of the cylinder is directed 3 to the sliding rack 1. 4
