Description

A kind of centerless grinder automatic loading/unloading equipment of grinding bearing roller

Technical field

The invention belongs to automated arm field, the centerless grinder relating to a kind of grinding bearing roller is automatic Loading and unloading equipment.

Background technology

Grinding is that one is with a long history, is widely used metal-removing process.Domestic, currently mainly Be applied to hard material that conventional tool is difficult to cut and precision, part processing that surface quality requirements is high. Along with what the appearance application of a large amount of new materials and scientific technological advance were brought newly wants element precision, quality Asking, grinding application increasing degree exceeds well over other traditional diamond-making techniques.Abroad, grinding is the widest Applying blank directly to process generally, instead of tradition cutting process at a lot of aspects, grinding machine quantity also reaches Lathe sum about 60%.

The centerless grinding of centerless grinder is the grinding that workpiece does not centers, have the highest machining accuracy from And be widely used in the grinding of bearing roller cylindrical.The advantage of its maximum is without carrying out workpiece Set and Positioning, this makes it to perform well in the occasion produced in enormous quantities, during the installation and debugging of each workpiece Between almost nil.The principal element affecting product quality and working (machining) efficiency is the artificial loading and unloading to equipment Journey.Present stage, centerless grinder loading and unloading are mainly by a set of manual handling equipment of artificial push-and-pull, it is achieved The loading and unloading that roller is processed on grinding machine.This mode roller after machining thus hand gear pull-out with There are frictional influence roller surface machining accuracy, switching processing tasks processing difference rule between hand gear Need to adjust the chute feeder of hand gear during the roller of lattice number, have a strong impact on processing efficiency.

The present invention is directed to above-mentioned existing manual handling equipment and affect surface processing accuracy and working (machining) efficiency The problem such as low, a kind of centerless grinder automatic loading/unloading equipment of design and automatically adjust handling equipment and improve and add Work progress and production efficiency.

Technical solution of the present invention is as follows: the present invention includes: the charging belt at two ends, centerless grinder left and right is defeated Sending machine and discharging belt conveyer to transport the bearing roller of loading and unloading, automatic mechanism sets according to before processing The processing specification feedback data put passes through bevel gear I, II and gear, rack gear adjustment to servomotor Stop that beam position above chute feeder meets different length specification roller demand process requirements, in described resistance Proximity transducer detection roller material is installed on gear beam put in place situation, after proximity transducer detection roller puts in place Feeding back signal to the push cylinder motion of Controlled by Programmable Controller side drives the chute feeder in the push skateboard of side to move to Predetermined feeding station, the front magnetic switch sensor being arranged in the push cylinder of side detection side push cylinder moves to Feed back to the vertical guide rod cylinder of Controlled by Programmable Controller after Wei to move downward at vertical direction, be arranged on perpendicular The magnetic switch detection vertical direction cylinder moving of straight guide rod cylinder lower end feeds back signal to after predetermined station Controlled by Programmable Controller left and right gas pawl captures at mill frame and the roller on chute feeder, is arranged on cleft hand Electric resistance sensor feeds back to Controlled by Programmable Controller side push cylinder and returns initial position, the most vertically guide rod Cylinder the most up moves, and the upper magnetic switch being arranged in vertical guide rod cylinder detects that guide rod cylinder is transported Move and after putting in place, feed back to the horizontal rectilinear motion cylinder that Controlled by Programmable Controller is arranged on the installing plate of left side Drive is arranged on slider I, II upper slide moves to the predetermined station in left side, is arranged on the upper left side joint of installing plate The nearly sensor detection slide plate situation of putting in place feeds back to the vertical guide rod cylinder of Controlled by Programmable Controller the most down Motion, the magnetic being arranged in vertical guide rod cylinder switch detects that guide rod cylinder motion is fed back after putting in place Unclamping to Controlled by Programmable Controller gas pawl, roller is placed on mill frame and blanking Belt Conveying by left and right gas pawl On machine, electric resistance sensor detection left and right cleft hand feeds back to Controlled by Programmable Controller device during roller and has returned Behind beginning position, grinding machine starts processing, and roller repeats after machining to capture work, the roller in feeding groove Capture roller in chute feeder with the roller on mill frame to realize the Tong Bu raising of roller loading and unloading and add work efficiency simultaneously Rate, the electric resistance sensor being arranged on handgrip detects state during roller loading and unloading in real time, it is to avoid roller is dashed forward So drop the security incident caused.
