Abstract

A multifunctional automatic spring testing machine, disclosed by the present invention, comprises an upper die, and the upper die comprises a multi-jaw chuck, a motor connected with the multi-jaw chuck and an adjusting cylinder located in the center of the multi-jaw chuck. Each jaw of the multi-jaw chuck is provided with a positioning spring in the radial direction, and the positioning springs extend to the outer wall of the adjusting cylinder. A connecting shaft penetrating through the adjusting cylinder along the radial direction of the clamping jaws is arranged in the positioning spring, one end of the connecting shaft is fixed to the multi-jaw chuck, and a metal gasket with an external thread is arranged at the other end of the connecting shaft and is arranged along the axial directionof the adjusting cylinder. The cross section of the metal gasket is arc-shaped, the end face, close to the multi-jaw chuck, of the metal gasket is coated with a permanent magnet material layer, and the motor works to enable the clamping jaws to drive the multiple metal gaskets to form a circular face so as to position a to-be-tested spring. According to the present invention, the problem that anexisting spring rigidity detection result is large in error is solved. The multifunctional automatic spring testing machine has the advantages of high spring rigidity detection precision, good applicability and the like.

Description

technical field [0001] The invention relates to the technical field of spring testing equipment, in particular to a multifunctional automatic spring testing machine. Background technique [0002] The spring testing machine is mainly used for strength and performance testing of various springs such as large-scale precision coil springs and discs, and is widely used in railways, military enterprises, industrial and mining enterprises, etc. [0003] The existing spring testing machine includes a lower mold, an upper mold, a transmission structure and a pressure sensor installed on the upper mold. The working principle is: through a lower mold with a built-in spring accommodation cavity, the spring is vertically placed in the spring accommodation cavity , so that the transmission structure drives the upper die down to compress the spring, so that the pressure sensor detects the load parameters of the spring, and the deformation of the spring is obtained through the transmission ...
