Rotary mechanical fixture matched with robot

Abstract

The invention relates to a rotary mechanical fixture matched with a robot. The rotary mechanical fixture comprises a connection seat, a plurality of clamping arms, a plurality of workpiece clamping jaws and a drive mechanism, wherein the connection seat comprises a connection part connected with a connection shaft of the robot, and a rotary disc rotationally arranged on the connection part aroundthe centre of the connection shaft; the plurality of clamping arms are uniformly distributed around the centre of the connection shaft and capable of being movably arranged on the rotary disc; the plurality of workpiece clamping jaws are arranged on the clamping arms in a manner of one-to-one correspondence; and the drive mechanism is arranged on the connection part and used for driving the rotarydisc to rotate around the connection shaft so that the plurality of clamping arms are synchronously collected towards the centre of the connection shaft or scattered from the centre to move. The rotary mechanical fixture disclosed by the invention facilitates control and butt joint for the robot, and is capable of automatically calibrating the centre, so that more stable and accurate clamping fora workpiece is achieved; and meanwhile, the rotary mechanical fixture is particularly applicable to workpiece location clamping taking the centre as reference, simple in structure, convenient to implement, and low in cost.

Description

technical field [0001] The invention belongs to the field of mechanical clamps, in particular to a rotary mechanical clamp matched with a robot. Background technique [0002] With the widespread use of robots, it not only greatly improves the processing efficiency of workpieces, but also facilitates the development and innovation of automated processing. [0003] At present, for workpiece fixtures, chuck type or multi-point positioning type are common to realize the positioning of the product to be processed. However, due to the complex structure, it is difficult to control accurately, and it is also difficult to connect with the robot, resulting in interruption of the automation program. , not only reduces the production efficiency, but also the accuracy of clamping is difficult to guarantee (especially the product processing based on the center), which directly affects the product processing quality. Contents of the invention [0004] The technical problem to be solved ...
