Unlimited rotation automatic clamping mechanism used for full automatic balance correcting equipment

Abstract

The invention discloses an unlimited rotation automatic clamping mechanism used for full automatic balance correcting equipment. The clamping mechanism is characterized in that an air claw is fixed in the center hole of an air claw sleeve, the air claw sleeve is fixed on an outer barrel of a rotating mechanism, one end of the air claw is connected with fingers of the air claw, and one end of a rotating shaft is fixed in the air claw sleeve far from the fingers of the air claw; the other end of the rotating shaft is sleeved on a rotating shaft sleeve, two star-type seal rings are utilized to seal the rotating shaft and the rotating shaft sleeve, and the rotating shaft between the two star-type seal rings is provided with an annular air flue; and the rotating shaft sleeve is fixed on the end face of the outer barrel of the rotating mechanism, the rotating shaft positioned outside the rotating shaft sleeve is provided with a synchronous belt pulley, a frictional resistance rotating air joint is arranged in a hole at the other end of the rotating shaft, and a common air joint is arranged on the rotating shaft sleeve. In the invention, a clamping workpiece can carry out unlimited rotation and the rotating friction torque is small, and the clamping mechanism is suitable for automated equipment required to automatically clamp a workpiece to rotate, such as the automatic clamp during circumferential positioning of the workpiece in a full automatic balance correcting machine and the like.

Description

technical field [0001] The invention relates to an automatic clamping mechanism, in particular to an infinitely rotating automatic clamping mechanism used for fully automatic balance correction equipment. Background technique [0002] Motors are important production and daily necessities. Among them, during the manufacturing process of the motor rotor, there is an initial unbalance due to the influence of materials, manufacturing processes and assembly. The motor rotor with excessive unbalance will produce vibration, bring noise, shorten product life, and even bring danger when it rotates at high speed. Therefore, it is necessary to perform dynamic balance correction on the motor rotor. [0003] The dynamic balance correction equipment used for motor rotors can be divided into two categories, namely, manual correction rotor dynamic balance machines and automatic rotor dynamic balance correction machines. The cost of manually correcting the dynamic balancing machine is low,...

AI Technical Summary

Problems solved by technology

The clamping force of the double-acting mechanism is large, but a large frictional torque will be generated when the sealing ring is ventilated, which makes the required driving torque larger, and it is difficult to reduce the volume of the entire mechanism as a result.
