Electrical rotary table limiting mechanism with rotary angle range not exceeding 360 degrees

Abstract

The invention relates to an electrical rotary table limiting mechanism with the rotary angle range not exceeding 360 degrees. The electrical rotary table limiting mechanism comprises a base, a rotary shaft, a deep groove ball bearing, a first support, a second support, a third support, a fourth support, a first travel switch, a second travel switch, a third travel switch, a fourth travel switch, a first projection, a second projection, a third projection, a fourth projection, an annular travel stopper and a rotary transformer. The electrical rotary table limiting mechanism is characterized in that the four supports are fixedly connected in the front, in the rear, on the left and on the right of the base respectively, are different in height and mounting angle and are the same in mounting radius, the annular travel stopper is sleeved on the rotary shaft below the rotary transformer, the side faces of the annular travel stopper extend outwards to form the four projections, the travel switches are fixedly connected on the supports, and when the electrical rotary table limiting mechanism is in operation, the travel switches and the four projections are used for adjusting the limiting state of a rotary table by means of butting and pressing. Therefore, the electrical rotary table limiting mechanism is simple, practical and low in cost and is capable of meeting requirements of large limiting angles.

Description

technical field [0001] The invention belongs to the technical field of turntable design, and relates to an electric limit mechanism of a turntable whose rotation angle range does not exceed 360°. Background technique [0002] For the turntable whose rotation angle range does not exceed 360°, setting two sets of electrical limit mechanisms can play the role of limit protection. Each group of electrical limit mechanisms has two sets of limit devices. The first set is the pre-limit position, which reduces the speed; the second set is the final limit position, which controls the motor to brake and stop the rotation. Each set of limit devices consists of limit switches and travel stops. [0003] When the electrical limit angle is large or the installation space is limited, there will be mutual interference during the installation and movement of each set of limit devices. Therefore, the traditional limit design method is difficult to achieve reliable limit protection. Conten...
