Description
Technical field
The utility model relates to Machining Technology field, relates in particular to a kind of floating clamping device.
Background technology
In the processing of bearing ring part, due to forging blank out-of-shape, need after rough turn processing, just can carry out finish turning processing at present, thereby ensure that part form and position tolerance is up to standard. But in process, also can there are some form errors, and use the hard pawl that floats can reach the object that reduces lasso form error, directly clamping forge piece blank surface. But also there are a lot of deficiencies in existing floating clamping device.
Documents 1, as shown in Figure 1, the patent that notification number is CN203197295U discloses a kind of floating claw, comprises jaw body and clamps claw, and described clamping claw is arranged on described jaw body by connector is rotating. Also there is following deficiency in this floating claw: 1, integral clamp is excessive, seriously exceeds diameter of chuck, can cause the interference of cutter, debugs improperly may cause security incident. 2, the excessive fixture total quality that causes of fixture is large, and scroll chuck can produce when rotated excessive centrifugal force and cause clamping force loss; Larger fixture quality can increase centrifugal force, causes workpiece easily to fly out and hurt sb.'s feelings. 3, the distance of acting points by clamping force to the distance at claw center much larger than fixture fixed screw to claw center, will form one taking jaw body as bar, taking the some lever as fulcrum that touches at jaw body and chuck edge, allow jaw body fixed screw bear more multidirectional outer pulling force, the damage probability that increases claw fixed screw and T-nut, also can increase the probability that fixture flies out. 4, the clamping range of holding workpiece is little, poor for applicability.
Documents 2, as shown in Figure 2, notification number is that the patent of CN103464800A discloses a kind of floating type New Thin-walled part turning positioner, comprise three-jaw body, contiguous block, clamped spiked and edge cover, described three-jaw body is connected on described contiguous block by described edge cover, described contiguous block is connected with lathe chuck, six described clamped spiked are fixed on respectively described three-jaw body inner side in pairs, described clamped spiked, taking described edge cover as fulcrum, rises and falls with thin-wall part cylindrical height together with three-jaw body, has floating of trace. Also there is following deficiency in this device: 1, the workpiece of this device clamping can be little a lot, but the tie point of its contiguous block and chuck still likely can exceed outside chuck, causes the interference of cutter, the damage of T-nut. 2, acting points by clamping force is to the distance at fixture center much smaller than fixture fixed screw until the distance at fixture center, can allow equally fixed screw bear more multidirectional outer pulling force, the damage probability that increases fixture fixed screw and T-nut, also can increase the probability that fixture flies out. 3, the clamping range of holding workpiece is little, poor for applicability.
Documents 3, as shown in Figure 3, notification number is that the patent of CN2013394661 discloses a kind of lathe clamp for bearing ring, comprises three aligning clamping systems that are separately positioned in three circumferential uniform grooves of power chuck edge: aligning clamping system comprises clamping part, running part; Described clamping part forms by two gripper jaws being arranged on to change in pawl grooves on two sides by screw a respectively; Described running part is fixed in chuck moving jaws upper groove and forms through rotating shaft, T shape slide block successively by screw and limit pendulum double-screw bolt, and running part is placed in the groove of power chuck; Running part is placed in clamping part bottom. Also there is following deficiency in this fixture: 1, rotating shaft is in the centre of two screw holes of base, and standard T-nut two screwed hole spacing are less, so this scheme need to be abandoned existing standard T-nut and change the special larger T-nut of screwed hole spacing into, increase manufacturing cost so for a moment, two can reduce the slidably distance of T-nut in T-slot, reduce clamping range. 2, rotating shaft and base design for integral type, because the required precision of rotating shaft is higher, the manufacture difficulty of this design is larger, has increased manufacturing cost. 3, whole clamp-shaped is higher, and quality is larger, causes clamping force loss larger when rotation because centrifugal force is excessive. 4, change the fixed screw that can block rotating shaft after pawl is installed, be not easy to dismounting debugging.
