Abstract

A bearing seat assembly line control system in supporting roller production utilizes a PLC controller as a center to control the whole process of positioning of each bunker, operation of assembly line, assembly of workpiece, feeding and blanking action of mechanical hand. A bearing bunker, an isolation ring bunker and a bearing seat bunker all adopt disc type arrangement, and the height and the angle of the bunkers are respectively adjusted by a servo motor; feeding, assembly, oil injection, press fitting and blanking of the bearing seat are all carried out on a recyclable chain conveyor line, and workpiece transportation between each bunker and the chain conveyor line adopts pneumatic mechanical hand; each bunker, the mechanical hand and the chain conveyor line are respectively provided with sensors for carrying out status detection and the sensors give the feedback to the PLC controller.

Description

Bearing seat assembly line control system during carrying roller is produced

Technical field

Bearing seat assembly line control system during carrying roller is produced is mainly used in the electrical control field that bearing seat is assembled automatic production line.

Background technology

In existing carrying roller product process, the automaticity of bearing seat assembling process is in lower, most of adopts that manually-operated is simple and mechanical to be accomplished, and this mode production efficiency is lower; Also have some to adopt industrial robot material loadings to cooperate equipment such as pressing machinees to accomplish, the hardware and software cost of this method aspect electrical control is all very high, brings heavy financial burden to manufacturing enterprise.

Summary of the invention

To above problem; In order to realize the high-level efficiency of robotization control; Can reach the saving cost again, the present invention has adopted following technical scheme: bearing feed bin, shading ring feed bin, bearing seat feed bin all adopt disc type to arrange, and the height and the angle of feed bin are controlled by servomotor respectively; The material loading of bearing seat, assembling, oiling, press-fit, each operation of blanking all carries out on a chain type pipeline capable of circulation; The chain type pipeline is driven by servomotor; Several station equidistance are arranged on the chain type pipeline, and the position of chain type pipeline is realized accurate location by PLC controller (5101) to the control of servomotor (5201); Feeding manipulator adopts the three-dimensional structure, is driven by cylinder; Each feed bin, mechanical arm and chain type pipeline are separately installed with sensor and carry out state-detection, and feed back to the PLC controller; PLC controller (5101) only need be controlled the solenoid valve (5302) that is connected on the cylinder gas circuit; Bearing feed bin, shading ring feed bin, bearing seat feed bin that mechanical arm is accomplished in the location gripping material of fixing a point be can realize, and chain type pipeline fix a point material loading, assembling, blanking operations moved to; PLC controller (5101) is realized the rotation of oiling machine and the hydraulic pressure supply of pressing machine through the relay (5303) of control linkage on oiling motor and hydraulic motor, and realizes oiling, the production operation that press-fits through the control to respective electrical magnet valve (5302).

The present invention program, simple efficient, not only realized the robotization of bearing seat assembling, also well practiced thrift the cost of equipment.

Description of drawings

Accompanying drawing one: bearing seat assembly line control system structural drawing.

Embodiment

After the energising of bearing seat assembly line, press reset button, all mechanical arms and storage bin are all got back to original state, and the chain type pipeline carries out the initial point detection and gets back to origin position simultaneously; At first the assembling station of chain-linked conveyer is carried out material loading by bearing feeding manipulator gripping bearing; After the bearing material loading is accomplished; The assembling station moves to the oiling station; Next simultaneously assembling station also moves to bearing material loading position, and when oiling machine carried out oiling, the bearing feeding manipulator carried out the bearing material loading to next one assembling station; Because the spacing of all assembling stations equates and can reciprocation cycle; So whole operations of bearing seat assemblings such as when chain-linked conveyer whenever once equaled to assemble the amount of movement of station spacing, different assembling stations can be accomplished bearing material loading, oiling, shading ring material loading, bearing seat material loading simultaneously, press-fits, assembly blanking.
