Detailed description of the invention
As shown in Figure 1, tire synchronous fixture, including top board 2 and base plate 6, between described top board and base plate, by coupling, stud 10 is fixing to be connected, gap is had between top board and base plate, for accommodating central gear, tooth bar, drive the parts such as cylinder, a piece central shaft is installed between described top board center and base plate center, on described central shaft, 1 central gear 3 is installed between top board and base plate, central gear can rotate with central shaft, circumferential edges along central gear is evenly distributed with 3 tooth bars 4, described 3 tooth bars engage in same level and all the time with central gear, each tooth bar is connected by 1 push pedal is fixing with the head of 1 piston rod driving cylinder 5 respectively, cylinder is driven to be fixed on top board or base plate, push pedal front end is also fixing with paw 9 to be connected；When driving the head of piston rod of cylinder to forward extend out, push pedal travels forward, and the paw of push pedal band carry-over bar and push pedal front end also travels forward, and paw can fasten with tire endoporus, non-interference during described 3 tooth bars motion.
Preferably, in order to preferably make each paw protrude horizontally up along straight path, reducing the stress of the piston rod front end driving cylinder, the lower surface at base plate is fixed with 3 line slideways 8, being sliding combined with slide block on described each line slideway, described push pedal is fixing with respective slide block to be connected.Under the promotion driving cylinder 5, paw can slide along the line slideway 8 being fixed on base plate 6.
Due to drive the piston rod of cylinder stretch out track and paw stretch out track not in same level, push pedal uses following structure, each push pedal all includes vertical push plate 71 and the horizontal push pedal 72 of fixing connection, described vertical push plate is fixed with the head driving cylinder piston rod and is connected and vertical with the direction of motion driving cylinder piston rod, described horizontal push pedal is vertical with vertical push plate, described horizontal push pedal is fixedly connected with a slide block, and described paw is fixed on the lower surface of horizontal push pedal.
Top board includes central shaft hole and equally distributed three the upper fins of radial direction along upper central shaft hole, described three upper fins are positioned in same level, the upper end of central shaft is arranged in upper central shaft hole by bearing, top board is arranged to the shape of three fins, can effectively alleviate the deadweight of top board.In like manner, base plate includes lower central shaft hole and equally distributed three the lower fins of radial direction along lower central shaft hole, and described three lower fins are positioned in same level, and the lower end of central shaft is arranged in lower central shaft hole by bearing.By 3 studs 10, upper and lower fin is fixedly connected into integrally between top board and base plate.
It is provided with lightening hole on three upper fins and/or three lower fins, alleviates the deadweight of top board and/or base plate further.
In order to prevent dust and impurity from falling into central gear and tooth bar, also for attractive in appearance, this tire synchronous fixture also includes the shell for top board and base plate being wrapped.
Central gear and/or tooth bar select the engineering plastics of high intensity to make, and fixture overall weight is less than 13 kilograms, and compact conformation takes up room little than conventional fixture；And maximum grip power is up to 45 kilograms, a usual regular size tyres for passenger cars about about 15 kilograms, the weight of existing fixture is typically slightly larger than clamped weighing load.So greatly reducing the load of robot, reducing the specification of robot hardware, having saved production cost.It addition, the motion between the gear of engineering plastics manufacture and tooth bar need not add lubricant, and the gear of metal material manufacture and tooth bar need lubrication, prevent lubricating oil drippage from impacting molding.
Paw is nylon paw or engineering plastics paw, can alleviate weight further, and paw is as the criterion to be capable of crawl tire endoporus, can use paw as shown in Figure 1,.
Tire synchronous fixture integral installation is on robot wrist 1, concrete, and robot wrist 1 and top board use screw attachment integral.During work, robot wrist 1 drives tire synchronous fixture to move to tire centerline, the most slack.Now three drive cylinder to simultaneously drive the motion of respective rack linear, rotated by central gear, realize three mutually restrictions driving cylinder and realize synchronizing, respective push pedal is promoted to move along a straight line along respective line slideway, thus three paws realizing being connected to push pedal front end stretch out simultaneously, synchronized movement, the chucking power equilibrium of three retaining parts can be realized, avoid the location pressing from both sides inclined tire effect postorder station, it also avoid chucking power skewness and cause tire obscission during clamping is changed.
