Abstract

The utility model provides a rotary apparatus that is characterized by comprising a sprocket drive mechanism, and the side of the sprocket drive mechanism is provided with a rotary mechanism. By moving the rotary mechanism to the side, lubricating oil or scraps generated by abrasion do not fall to a plate no matter how a moving part moves; and meanwhile, a servo motor is used in the sprocket drive mechanism for driving rotation to replace the telescoping of an air cylinder, thus better stabilizing the entire rotary device. The rotary apparatus has the advantages that the lubricating oil of the moving part and the scraps generated by abrasion do not fall to the plate and the whole rotary apparatus is more stable simultaneously.

Description

A kind of slewing arrangement

Technical field

The utility model relates to a kind of slewing arrangement, is used for the level and the heeling condition of plate are changed mutually on the pcb board automatic production lines, belongs to the slewing arrangement technical field.

Background technology

The effect of rotating mechanism is the mechanism's rotation that drives the carrying plate, and plate is changed mutually in level and heeling condition.When general rotating mechanism was worked, spinning movement was finished by the expanding-contracting action that is fixed on the cylinder on the frame.Under the drive that the rotating mechanism inside cylinder stretches, drive the lifting of carrying plate by the floating junction plate, slide rail is mechanism's guiding of carrying plate by 3060 section bars.

This mode since movable parts directly over, can make lubricating oil and the bits that drop because of movable parts wearing and tearing drop on plate, influence the quality of plate, even causes the plate damage.And the rotation of rotating mechanism, the inner lifting of rotating mechanism all are to finish by stretching of cylinder, and the instability of air feed can directly influence the instability of rotating mechanism operation, and the lift cylinder in the rotating mechanism is died and can be caused the damage of plate sometimes.

Summary of the invention

The purpose of this utility model provides bits that a kind of lubricating oil that does not allow movable parts and wearing and tearing produce and drops to slewing arrangement on the plate.

In order to achieve the above object, the technical solution of the utility model has provided a kind of slewing arrangement, it is characterized in that, comprises sprocket drive, is provided with rotating mechanism at the side of sprocket drive.

The utility model moves on to side with rotating mechanism, and so no matter how movable parts moves, and the bits that lubricating oil or wearing and tearing generation can not take place drop on the plate; Simultaneously, in sprocket drive, use servo motor driven to rotate to replace substituting cylinder and stretch, make that whole slewing arrangement is more stable.

The utility model has the advantages that: the bits that the lubricating oil of movable parts and wearing and tearing produce can not drop on plate, and whole slewing arrangement is more stable simultaneously.
