Embodiment 1

[0038] The automatic test device for scales of the present invention comprises a workbench 1, a scale body 2 is arranged on the upper end of the workbench 1, a top plate 3 is arranged above the workbench 1, and a rotatable weight store is arranged above the workbench 1 5. A plurality of weight strings 6 are suspended from the weight storehouse 5. A telescopic assembly 7 capable of lifting and moving is arranged above the workbench 1. A mechanical claw 702 capable of grabbing the weight string 6 is installed at the lower end of the telescopic assembly 7. The assembly 7 is equipped with a sliding seat 704 which can move in a direction close to the weight storehouse 5 .

[0039]After adopting the above-mentioned technical scheme: the present invention is provided with a rotatable weight storehouse 5, a plurality of weight strings 6 are suspended from the weight storehouse 5, and a mechanical claw 702 capable of grabbing the weight strings 6 is set on the upper end of the workbench...

Embodiment 2

[0041] This embodiment is further optimized on the basis of Embodiment 1 as follows: the weight storehouse 5 includes a servo motor 502 and a rotating disk 501; The rotating disks 501 are connected to each other, the periphery of the rotating disk 501 is provided with a plurality of first placement holes 5011, the outer wall of the first placement holes 5011 is provided with a first guide groove 5013 penetrating through the side wall of the rotating disk 501, and the upper end of the weight string 6 is arranged There is a positioning column 8 with a diameter smaller than the first guide groove 5013 , and a first limiting block 801 is provided on the upper end of the positioning column 8 .

[0042] After adopting the above technical solution: the rotation of the rotating disk 501 is driven by the servo motor 502, which facilitates the control of each rotation angle of the rotating disk 501, and ensures that after each rotation of a certain angle, the positioning columns 8 of the...

Embodiment 3

[0044] This embodiment is further optimized on the basis of Embodiment 1 as follows: the positioning column 8 is provided with a second limit block 802 located at the lower end of the first limit block 801, the first limit block 801 and the second limit block The distance between the blocks 802 is greater than the thickness of the rotating disk 501, the second placement hole 7021 is opened through the mechanical claw 702, the side wall of the second placement hole 7021 is provided with a second guide groove 7023 penetrating the side wall of the mechanical claw 702, the second The width of the guide groove 7023 is greater than the diameter of the positioning post 8 .

[0045] After adopting the above technical solution: the mechanical claw 702 is provided with a second placement hole 7021 and a second guide groove 7023, when the weight string 6 needs to be grasped, the positioning column 8 located below the second limit block 802 passes through the second guide groove 7023 Ente...

Abstract

The invention discloses an automatic testing device for a scale, and relates to the technical field of testing devices for scales. A scale body is arranged at the upper end of a workbench, a top plateis further arranged above the workbench, a rotatable weight library is further arranged above the workbench, a plurality of weight strings are hung on the weight library, a telescopic assembly capable of moving in a lifting mode is arranged above the workbench, a mechanical claw capable of grabbing the weight strings is installed at the lower end of the telescopic assembly, the telescopic assembly is provided with a sliding seat, and the sliding seat can move in the direction close to the weight library. Weight strings of different masses can be grabbed and then placed on the scale for testing, the weight strings are moved out for repeated testing after testing is completed, the labor intensity of workers is reduced, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of a test device for scales, in particular to an automatic test device for scales. Background technique [0002] A scale is a weighing instrument used to measure the weight of an object. In modern mass measurement, weights are standard measuring tools for mass value transfer. [0003] After the scale is manufactured, it often needs to be tested for weighing performance, eccentric load, linearity, repeatability and tare. However, in the prior art, it is often necessary to manually take the weights and then load them on the scale, and then take them off one by one after the test. The error is large. [0004] Therefore, there is an urgent need for an automatic test device for scales, which can automatically select the corresponding weight strings according to the range of different scales, and perform calibration, linearity, partial load, repeatability and tare performance tests on the scales according to th...
