Description

Technical Field

[0001] The utility model relates to the technical field of disc spring detection, in particular to a disc spring finished product inspection device. Background Art

[0002] In the prior art, the disc spring finished product inspection equipment includes a disc spring compression resistance testing equipment, which includes a working platform, a pressure sensor and an extrusion device. A placement groove or a guide rod is formed on the working platform, and a pressure sensor is installed at one end of the placement groove or the guide rod. The pressure sensor is used to sense the pressure exerted on the disc spring when it is squeezed. An extrusion device is installed at the other end. The extrusion device squeezes the disc spring, detects the pressure during extrusion, and then detects the deformation of the disc spring, thereby judging the compression resistance of the disc spring.

[0003] During the inspection, if the center line of the disc spring is not in a straight line, the test result will be inaccurate. Since disc springs have different models, the inner hole diameters of disc springs are different, and the guide rod has a guiding effect on the disc spring, the existing guide rod specifications are fixed, so one device can only detect disc springs of one specification, which is of low practicality. Therefore, those skilled in the art provide a disc spring finished product inspection device to solve the problems raised in the above background technology. Utility Model Content

When the bidirectional screw rotates, the threaded sleeve moves relatively in the second sliding groove under the limitation of the second sliding groove. During the movement of the threaded sleeve, the connecting rod drives the pressure plate to expand under the limitation of the connecting piece at the other end, so that the pressure plates on the peripheral side of the limiting sleeve are all expanded outward, thereby achieving the effect of being suitable for disc springs of different specifications.

[0009] Preferably, a slot is provided on the inner wall of the pressure ring, and the pressure strip is slidably connected to the pressure ring through the slot. Therefore, when facing disc springs of different specifications, the disc spring can be squeezed by adjusting the position of the pressure strip to avoid uneven force on the disc spring.
