Description
Technical field
The present invention relates to a kind of feedway, specifically relate to the vehicle body automatic positioning equipment on a kind of roller bed.
Background technology
The Painting Shop of automobile manufacturing enterprise is all hand spray mostly, so there is no the relative skid of vehicle body and skid with respect to the requirement of the positioning precision of roller bed.And in whole painting process, vehicle body need to be combined through disengaging repeatedly with skid again, be to improve the conveying efficiency of vehicle body, at vehicle body on suspender and vehicle body on skid, all do not use finger setting.Along with reaching the standard grade of Control During Paint Spraying by Robot project, it is pinpoint during Control During Paint Spraying by Robot, requiring vehicle body and skid, and all the other most of stations there is no accurate positioning requirements, institute thinks and reduces scrap build amount and workman's work capacity, only before Control During Paint Spraying by Robot station by manually completing the accurate location of vehicle body and skid.
For completing above-mentioned design plan, existing skid is transformed, make itself and vehicle body realize finger setting, and require locating dowel pin manual operation to stretch, when needs are accurately located, location is stretched out, it is coordinated with vehicle body knock hole and realize accurately location.When accurately locating station, locating dowel pin retraction locating dowel pin mounting hole, without it is coordinated with vehicle body.For example, publication number is that the patent documentation of CN102442543A discloses a kind of automobile body conveying device, comprise roller bed, the roller of roller bed is provided with skid, skid comprise ladder shape skid body, be fixed on support assembly and locating assembly on skid body, wherein skid body below is provided with bracing frame, and bracing frame two ends are arranged with some and Universal caster platform skid Ontology Matching, and bracing frame is connected with the actuating device that is fixed on roller bed inner side.During use, actuating device drives bracing frame that skid body is lifted, when skid and vehicle body approach soon, and suspender and skid while stop motion, manually adjust the relative position of skid on bracing frame, the locating dowel pin of locating assembly and the auxiliary hole position of vehicle body are docked; Suspender is continued, toward declining, body in white to be turned and drop down onto skid, and the support assembly of skid is used for supporting vehicle body, and the locating dowel pin on the locating assembly of skid, for docking the auxiliary hole of vehicle body, is realized the accurate location of skid to vehicle body.This automobile body conveying device, installs small and exquisite compact conformation, and use safety simple to operate is time saving and energy saving; By set up the device of auxiliary skid location vehicle body on roller bed; increased the relative position degree of freedom of skid; make the skid can adjustment position, all around; guarantee that the locating dowel pin on skid can dock with vehicle body auxiliary hole; thereby reach the object of accurate location vehicle body; be conducive to automatic arc spraying vehicle body, be also conducive to improve the work efficiency of Detroit automation in car production.
Yet, realize the accurate location that makes vehicle body and skid before Control During Paint Spraying by Robot station, must guarantee that vehicle body, skid and roller bed three accurately locate, publication number is that the patent documentation of CN102442543A only discloses the location between vehicle body and skid, skid is not accurately located, thoroughly do not solve vehicle body and enter the pinpoint technical matters before Control During Paint Spraying by Robot station.At vehicle body, enter after painting workshop, need manually further to adjust, reduced the spray efficiency of robot, increased field staff's labour intensity.
Summary of the invention
The invention provides the vehicle body automatic positioning equipment on a kind of roller bed, utilize this delivery system, can complete the accurate location between vehicle body, skid and roller bed three, improved the spray efficiency of painting workshop, reduce field staff's labour intensity, reduced vehicle spray painting cost.
A vehicle body automatic positioning equipment on roller bed, comprises roller bed, with the skid of roller bed bearing fit and be fixed on the vehicle body detent mechanism on skid, also comprises skid clamping mechanism and vehicle body control apparatus on the mount pad that is fixed on described roller bed; Described vehicle body control apparatus comprises supporting seat, be fixed on supporting seat below drives the jacking apparatus that supporting seat moves up and down and the vehicle body support portion that is fixedly connected on supporting seat top, described vehicle body support portion comprises and is fixedly connected on the slide rail of supporting seat end face and the bracing frame that can move back and forth along slide rail, and the direction of slide rail is parallel with skid service direction; Described bracing frame top be fixedly connected with pallet and with the back-up block of pallet bearing fit.
