Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] The force standard machine with independent weighting includes the main frame 1 and the weight hanging 2. The main frame 1 is equipped with 9 weights 3 and 9 sets of motion mechanisms arranged vertically in layers. Each set of motion mechanisms includes two pairs of supports. Corner 4, a pair of brackets 5, a pair of servo motors 6, a pair of reducers 7, a pair of worm gear pairs 8; A pair of force sensors 10 are arranged on each bracket 5, and a weight 3 is placed on each pair of brackets 5. Such as Figure 1-4 .

[0019] The masses of the nine weights 3 are combined in multiples of 1, 1, 2, 5, 10, 20, 20, 20, and 20; the mass of the weight hanging 2 is twice that of the multiple of 1.

[0020] Bracket 5 is a ball screw bracket.

[0021] Taking the 100kN force standard machine as the embodiment of the present invention, the 9 static weights ...

Abstract

The invention discloses an independent weight adding force standard machine and an independent weight adding method, which belong to the technical fields of quality standard and measurement. The independent weight adding force standard machine comprises a main stand and a weight hanger, nine weights and nine groups of motion mechanisms are longitudinally arranged layer by layer in the main stand, and each group of motion mechanism comprises two pairs of supporting corners, a pair of brackets, a pair of servo motors, a pair of speed reducers and a pair of worm gear pairs; each servo motor is sequentially connected with each speed reducer, each worm gear pair and each bracket, a pair of force sensors is arranged on each bracket, and a weight is placed on each pair of brackets. In the independent weight adding method, each servo motor drives the brackets and the weights placed at the upper surfaces to move up and down through each speed reducer and each worm gear pair. The weights are rapidly and steadily added and unloaded, thereby realizing the maximum loading series and enlarging the use measuring range of the detected sensor; the control method and processes are simple, and the energy saving effect is remarkable.

Description

Technical field [0001] The invention relates to a standard device for force value or mass measurement, in particular to a force standard machine and a force (weight) method, belonging to the technical field of quality standards and measurement. Background technique [0002] At present, the existing force standard machine is a loading method that does not exchange weights. It uses a lifting platform to place one group (or two groups) of overlapping weights (generally 10 equal-mass weights are 10 force One group of weights), one by one, added to the suspension of the load frame of the force standard machine; this method can realize one set of weights with one range (or two sets of weights with two ranges) at equal intervals of 10 force levels , Equal rate step-by-step loading. Another way of exchanging weights in the existing force standard machine is to configure a group of weights according to the multiple relationship of a single 1, 2, 5 and several 10s, and use the way of...
