Embodiment

[0020] The invention provides an eccentric turntable device, such as Figure 1 ~ Figure 3 As shown, it includes a base 1, a support frame 2, a center of gravity adjustment block 3, a load fixing ring 4, a rotating frame 5, a geared motor and a control line 6, a motor fixing frame 7, a bearing 8, and a rotating shaft 9. The base 1 is a square plate with a size of 170mm×70mm×8mm, and several mounting holes are reserved. The lower part of the support frame 2 is fixed on the base by screw connection. The upper part of the support frame 2 is a circular support with a maximum outer diameter of 160mm, a hollow diameter of the inner ring of 150mm, and a square central fixed bearing part with a size of 25mm. ×25mm, supported and fixed by three ribs with a thickness of 3mm and a width of 28mm. The rotating shaft 9 is rigidly connected (interference fit) on the inner ring of the bearing 8, and the bearing 8 is installed in the hollow part of the support frame 2. One end of the rotating...

Abstract

The invention provides a hollow eccentric rotary table comprising a base, a supporting rack, a bearing, a rotating shaft, a motor, a rotating frame and a load fixing ring. The lower portion of the supporting rack is fixed to the base; the upper portion of the supporting rack is a round support; the bearing is fixed in the round support; the rotating shaft is connected in an inner ring of the bearing; one end of the rotating shaft is connected with the motor and the other end is connected with the rotating frame; the load fixing ring is connected to the rotating frame. The middle blocking area of the rotating part of the rotary table is small and electromagnetic waves can penetrate optical element loads with fewer middle parts; the hollow eccentric rotary table has the advantages of high response speed, low weight and reduction of vibration, noise and abrasion.

Description

technical field [0001] The invention relates to the field of a rotating table for rotating objects, in particular to an eccentric rotating table which is hollow and unobstructed, and drives a wedge-shaped lens to rotate to expand the field of view. Background technique [0002] Some existing turntable devices are all driven by a driving mechanism so that the turntable rotates and the load (workpiece) on the turntable rotates with the turntable. However, few of the existing turntables are hollow and unobstructed in the middle, and cannot meet the requirements of hollow large diameter (especially hollow diameter of 150mm and above) and high speed (600r / min). Most of the existing hollow industrial turntables are very bulky, large in size and high in power consumption. When the load is an eccentric structure, the center of gravity cannot be adjusted, and the equipment vibrates greatly during use, resulting in greater noise and equipment wear. Contents of the invention [000...
