Feeding mechanical arm of meter lathe

Abstract

The invention discloses an instrument lathe feeding and conveying manipulator, comprising a bracket; the middle of the bracket is hollowly provided with a driving gear; one side at the upper part of the bracket is fixedly provided with a carriage provided with a sliding plate; the front end of the sliding plate is provided with a material inlet slideway; the tail of the sliding plate is provided with a feeding large-hump, and an inclined plane of the feeding large-hump faces backwards; the rear part of the feeding large-hump is provided with an eccentric wheel which pushes against the feedinglarge-hump; the other side of the bracket corresponding to the carriage is provided with a returning gear; the external side of the returning gear is intermittently provided with a semi-circular discwhich has the same shaft with the returning gear; an arc bumping and a triangle bumping are sequentially and coaxially arranged in the gap between the semi-circular disc and the returning gear; the two bumpings are not arranged on the same plane and respectively arranged on the semi-circular edge of the semi-circular disc. Compared with the existing instrument lathe feeding and conveying manipulator, the instrument lathe feeding and conveying manipulator of the invention has the advantages of precise feeding, conveying and returning positioning, effectively solves the clamping problem of the workpieces, prolongs the service life of the parts, and is also beneficial to improving the processing efficiency and the processing quality of the products at the same time.

Description

technical field [0001] The invention relates to a feeding and feeding manipulator, in particular to an instrument lathe feeding and feeding manipulator. Background technique [0002] The feeding and feeding manipulator of the instrument lathe currently in use is an eccentric wheel mechanism. When the eccentric wheel moves from the smallest radius part to the large radius part, it drives the feeding part to realize feeding and further stretches the return spring until the eccentric wheel turns to At the part with the largest radius, at this time, the constant radius motion is maintained for a certain period of time to feed, and then the eccentric wheel runs from the largest radius part to the small radius part, and the feeding part makes a return movement under the action of the restoring force of the return spring until the eccentric wheel turns to At the smallest radius, a complete primary feed is achieved. Although the structure of the device is simple, after many years o...

Problems solved by technology

Although the structure of the device is simple, after many years of use, it has been found that because the return stroke of the entire device only depends on the restoring force of the return spring, there is an inertial force in the feeding part when it moves, making it difficult to position the feeding part to reach the limit position. Oscillations often occur when the initial position of the feed material is reached, especially when the return spring of the equipment is fatigued after a long time of operation, which makes the jamming phenomenon frequent in actual production. On the one hand, it will cause damage to parts, on the other hand It also makes it difficult to improve processing efficiency and quality
