Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without making creative efforts belong to the protection scope of the present invention.
As shown in fig. 1-5, the utility model discloses milligram level weight automatic verification equipment, including work platform 1, X is to drive arrangement 2, two Y are to drive arrangement 3 and Z to drive arrangement 4, weight measuring device 5 and weight shelving plate 6, two Y are to drive arrangement 3 parallel arrangement and install on work platform 1, X spanes between two Y to drive arrangement 3 to drive arrangement 2, Z is to vertical the installing on X is to drive arrangement 2 to drive arrangement 4, weight measuring device 4 and weight shelving plate 6 also set up on work platform 1 and are located Z to the regional below of drive arrangement 4 activity, Z is to the pneumatic device of inhaling of putting the milligram level weight that is connected with of the end that stretches out of drive arrangement 4.
One of the Y-direction driving devices 3 is an active driving device, and the other Y-direction driving device 3 is a passive driving device. The driving device and the X-direction driving device 2 respectively comprise a motor, a lead screw, a linear guide rail and a sliding block arranged in the linear guide rail, the motor drives the lead screw to rotate to drive the sliding block connected with the lead screw in a rotating mode to move in the linear guide rail, and the Z-direction driving device 4 is an air cylinder.
