A rotation and translation device

Abstract

The invention discloses a rotary translation device which comprises a swing part; the swing part comprises a rotating shaft, a swing arm, a support bracket and a damping component; the swing arm swings around a first end; a second end of the swing arm sleeves the rotating shaft to rotate relative to the rotating shaft; one end of the support bracket is provided with a supporting groove for supporting a workpiece horizontally; the other end of the support bracket is fixedly connected with the rotating shaft and is used for driving the rotating shaft to rotate in the first direction under the gravity action of the workpiece; and a first end of the damping component is fixed relative to the swing center of the swing arm; and a second end of the damping component is fixedly connected with therotating shaft to drive the rotating shaft to rotate in the direction opposite to the first direction when swinging around the swing arm. The support bracket drives the rotating shaft to rotate in thefirst direction under the gravity action of the workpiece, and the damping component drives the rotating shaft to rotate in the direction opposite to the first direction, so that the workpiece can bealways on the support bracket; and the supporting groove can support the workpiece horizontally, so that the workpiece is always in the horizontal state to be transferred to a target position from aninitial position in the swing process of the swing arm, and therefore, the rotary translation device provided by the invention can be always in the horizontal state to transfer the workpiece.

Description

technical field [0001] The invention relates to the field of automatic production lines, in particular to a rotary translation device. Background technique [0002] With the unprecedented development of the manufacturing industry, higher requirements have been put forward for the manufacturing industry, and high precision and high efficiency have increasingly become the highest goals in the manufacturing field. [0003] The existing manufacturing industry is usually inseparable from the automatic production line, and the automatic production line usually includes a large number of transfer equipment to transfer workpieces between different processing equipment, so it is particularly necessary to improve the transfer equipment of workpieces. [0004] Taking the processing of shaft workpieces as an example, in the processing processes such as turning, grinding and straightening, the shaft parts are usually grasped manually or with a robot, and the shaft parts are placed betwee...

Problems solved by technology

However, since the two ends of the shaft parts usually have a certain degree of inclination when the shaft parts are transported manually or by manipulators, there is a certain height difference between the centers of the two ends of the shaft parts, and it is impossible to ensure that the shaft parts are transported in a horizontal state Between the two tops, there is a large deviation between the actual central axis formed by the two ends of the clamped shaft part and the theoretical central axis of the shaft part, so that the coaxiality error of the shaft part is large , which seriously affects the machining accuracy of shaft parts

[0005] Therefore, the existing automatic production line lacks the transfer equipment that can make the workpiece be transferred in a horizontal state all the time
