An automatic fixture for centrifugal machinery

Abstract

The invention discloses an automated fixture for a centrifugal machine and mainly relates to a fixture. The automated fixture comprises a centrifugal rotating shaft, a bearing support, a lifting table, fixture driving mechanisms and fixture device assemblies, wherein a plurality of servo air cylinders connected with the top of the lifting table are arranged at the bottom of a bearing seat; the fixture driving mechanisms comprise connecting bars and rocking bars; the fixture device assemblies comprise bar seats and clamping devices; the clamping devices comprise middle plates, rotating shafts and fixed shafts; connecting plates are arranged at the tail ends of both sides of the rotating shafts and the fixed shafts; clamping columns are arranged on the connecting plates; and buckling groovesare formed in the clamping columns. The automated fixture disclosed by the invention has the following beneficial effects: the automated fixture and a centrifugal driving mechanism of the centrifugalmachine are connected to form a complete-set integrated structure, so that not only can the dismounting and mounting operation be facilitated, but also the center of the automated fixture and the rotating center of the centrifugal rotating shaft can be well positioned on a vertical line; furthermore, a centrifugal liquid accommodating barrel can be fixed on the automated fixture in an automated control manner; an operating process of the preliminary centrifugal work is simple, time-saving and labor-saving; and the efficiency of the centrifugal work can be greatly improved.

Description

technical field [0001] The invention relates to a fixture, in particular to an automatic fixture for a centrifugal machine. Background technique [0002] When a vertical centrifugal machine is used for centrifugal filtration of liquid solvents, the existing fixture is a manual fixture, and the fixture body is set separately from the centrifugal drive mechanism (such as the centrifugal shaft) of the centrifugal machine, and the fixture is fixed to the seat plate ( The seat plate is used to place the centrifuge bucket), in order to be more stable during the rotation, the center of the centrifuge bucket should be on a vertical line with the rotation center, so it is necessary to ensure the fixture for fixing the centrifuge bucket The center should be on a vertical line with the center of rotation. Therefore, when fixing the fixture to the seat plate, the position of the fixture must be adjusted to ensure that the center of the fixture is on a vertical line with the center of ro...

[0002] When a vertical centrifugal machine is used for centrifugal filtration of liquid solvents, the existing fixture is a manual fixture, and the fixture body is set separately from the centrifugal drive mechanism (such as the centrifugal shaft) of the centrifugal machine, and the fixture is fixed to the seat plate ( The seat plate is used to place the centrifuge bucket), in order to be more stable during the rotation, the center of the centrifuge bucket should be on a vertical line with the rotation center, so it is necessary to ensure the fixture for fixing the centrifuge bucket The center should be on a vertical line with the center of rotation. Therefore, when fixing the fixture to the seat plate, the position of the fixture must be adjusted to ensure that the center of the fixture is on a vertical line with the center of rotation. Position the fixture during use. The adjustment is time-consuming and inconvenient; and the fixture is a manual fixture, which requires manpower to apply force to the fixture to fix the centrifuge bucket to the fixture, which is time-consuming and labor-intensive

To sum up, the operation process of pre-centrifugation work is cumbersome, time-consuming and labor-intensive, which reduces the efficiency of centrifugation work
