Известно устройство дл удалет1 грата с кольцевых заготовок, содержащее смонтирован ) на станине и соединенные с приводом режущий узел, выполненный в виде двух гфиводных валов с ножами, и приспособление дл зажати заготовки с приводом его перемещени Недостатком данного устройства вл етс то, что вследствие значительныхA device for removing grats from ring blanks is known, which comprises: a cutting unit made in the form of two double-sided shafts with knives mounted on a frame and connected to a drive; and a device for clamping the workpiece with a drive for moving it. The disadvantage of this device is that due to significant

Claims

The device for removing burrs contains a clamp 1 and a cutting assembly, made in the form of 5 drills 3 mounted on the drive shafts 2 with shafts 4 fixed in their lap 4. Drive shafts 2 are kinematically. And are connected to the drive 5 of the machine and the clamp movement 1 of the workpiece 6. Fixture For the bite, the bite is made in the form of a crank-beam mechanism having an eccentric 7 mounted on the water shaft 2, connected to the rocker 8 by means of a tongue 9. The arm 8 is pivotally connected by an intermediate link 10 to one of the two shoulder legs 11slide-slider mechanism, the slider 12 of which bears the pressure 1. The shoulders of the two arms 11 are spaced apart on the swing axis 13 and are connected to each other by an elastic torsion element 14. The deburring device operates as follows. In the initial position, the workpiece 6 is installed in the working area of the machine, and the clamp 1 is located in the extreme upper position. When the machine is turned on, the rotation from the drive 5 is transmitted to the abans 3 with the knives 4 and the eccentric 7 mounted on one of the shafts 2, mounted on the drive shafts 2, and then through interconnected by an intermediate link 10 of the crank-and-yoke and slide-slider mechanisms - the clamp 1, which moves in the direction of the workpiece 6, in the result of which before the knives 4 enter the zone of treatment of flash the fixation and the workpiece 6, after which the knives 4 enter into the zone of treatment of burr and cut off the latter. Then the clamp 1 returns to the initial position at which the machine is stopped and the workpiece is removed from the work area. After installing the new workpiece into the working area, the cycle of operation of the machine is repeated. If the wall thickness of the next billet turns out to be larger than the previous one, then while fixing the grip, an elastic torsion element 14 joins the shoulders of the two shoulders 11, thus eliminating residual deformations on the surface of the billet. The invention of the Device for removing the bur from the welded ring blanks, comprising a cutting assembly mounted on the frame and connected to the drive, made in the form of two drive shafts with knives, and a device for clamping the workpiece with the drive of its movement, characterized in that With the aim of increasing the reliability and service life of the device, the drive for moving the device for clamping the workpiece is made in the form of interconnected slide-slider mechanism with a two-arm rocker and an eccentric crank bark myslovogo Mexaiffl3Ma, cam fixed to the drive shaft of NZ knives, and is provided with a resilient torsion member connecting said two-armed rocker arms. Sources of information taken into account in the examination: 1. A machine for cutting burr from the rims of wheels of the C-118 model developed by the Gorky Automobile Plant (drawing C 118-О2 dated January 29, 1996).
