Embodiment Construction

[0019] Below in conjunction with accompanying drawing, the present invention will be described in further detail:

[0020] Such as figure 1 and figure 2 As shown, the present invention discloses a compression spring testing device, comprising a steel base 1, above which is a work area, outside the work area is a transparent cabinet 6 surrounded by plexiglass, the transparent cabinet 6 front and back are set as plexiglass doors 3 . The following working parts are all arranged inside the transparent cabinet body 6, so that on the one hand, it is convenient to test under isolated conditions, and on the other hand, the testing process can be monitored.

[0021] A stepping motor 13 is arranged inside the base 1 , and the stepping motor 13 is connected with a precision screw 11 through a shaft coupling 12 . The precision screw 11 is arranged above the base 1 and inside the transparent cabinet 6 . When the stepping motor 13 rotates, it drives the precision screw mandrel 11 to ro...

Abstract

The invention discloses a pressure spring testing device, comprising a steel base. The steel base is internally equipped with a stepping motor which is connected with a precision lead screw via a coupling, the precision lead screw is arranged at the upper part of the base and is connected with a movable aluminum plate rack, two ends of the movable aluminum plate are arranged on a support rack viaa rectilinear motion pair, the lower surface of the movable aluminum plate is provided with a pressure head, a spring positioning base fixed on a pedestal is arranged just below the pressure head, the pedestal is internally provided with a sensor which is connected to an electric control box arranged at the side part of the base. The pressure spring testing device has the advantages of convenientand fast operation, high test precision, fast test speed and great convenience for batch test.

Description

technical field [0001] The invention relates to a device for testing the elastic limit by using mechanical stress, in particular to a device for testing force value parameters of a compression spring. Background technique [0002] The pressure spring needs to be tested before use, because if it is not tested, there will be product problems due to the performance of the compression spring not meeting the conditions during specific use. In this way, the product needs to be dismantled and reassembled, which is not only time-consuming and laborious, but also greatly increases the production cost due to rework. Therefore, before use and assembly, the pressure spring is usually tested and screened to avoid losses due to its failure. [0003] Most of the compression spring test devices currently used are manually operated, and some of them are pointer-type force measurement, which has problems such as low test accuracy, long test cycle, and unsuitable for batch testing.
