Automatic orderly weight adding mechanism

Abstract

The invention discloses an automatic orderly weight adding mechanism, comprising a plurality of plate shaped weights 4, a weighing part and a loading-unloading part. The weighing part comprises a weighing plate 11. The loading-unloading part comprises support column components 3. Each support column component 3 comprises a support column 31 whose lower-part rod section is an optical rod section; a sleeving tube 33 sleeving the optical rod section in sequence, and an elastic body 32 topped between the support column and the sleeving tube. The upper-part rod sections of the support columns and the outer part of the sleeving tubes are provided with outwardly protruding support steps 69 arranged in the axial direction and at interval. The lower ends of the optical rod sections of the support columns are fixedly arranged on the lifting platform 2 that is arranged horizontally and driven to lift by a driving mechanism. Each sleeving tube is provided with an external support body 5 used to restrict the sleeving tube from falling to the lowest position. The mechanism of the invention aims to reducing the dimension in the vertical direction, to reducing the fabricating difficulty and to increasing the operation precision of equipment and provides this automatic orderly weight adding mechanism. With such a designed structure, the increase in the number of weights under a specific size can be realized so as to realize the goals of a compact structure and an enlarged measurement scope.

Description

technical field [0001] The invention relates to an automatic weight adding device, in particular to an automatic weight adding device applied in the field of pressure detection. Background technique [0002] In the automatic weighting mechanism of the prior art, the support column is a non-equidistant mechanism, and the distance between the edge of the weight and the bottom surface (or top surface) is not constant. The manufacturing difficulty of the support column is high, and due to the edge size of the weight There are many types, and the probability of making mistakes is high, and when assembling the weights, due to the poor versatility of each weight, it is easy to make mistakes when using the equipment. In particular, the disk-shaped weight driving mechanism and the cylindrical weight loading mechanism of the automatic weighting mechanism occupy a large space, and the excessive space occupied in the vertical direction makes it difficult to manufacture parts.
