Description
Technical field
The present invention relates to a kind of workpiece clamping, supporting, positioner, be specifically related to a kind of clamping device being applicable to inner circle hole workpiece.
Background technology
In dish class, the parts fixation of circular hole is a difficulty of mechanical field clamping always, such as chain pulley seat, chain pulley seat is as the vitals of car, vital effect is served in car, therefore the processing of chain pulley seat is a very important operation, especially the location of chain pulley seat, now commercially lacks this device.
At present, the fixed form of chain pulley seat adopts traditional triangle chuck, scroll chuck utilizes moving radially of three movable jaws be distributed on chuck body, the machine tool accessories of Workpiece clamping and location, scroll chuck uses of a specified duration, along with the wearing and tearing three-jaw of chuck there will be bell mouth shape, three-jaw also can slowly depart from lathe spindle center.The form and position tolerance of institute's processing parts is increased.In addition, triangle chuck to aluminum-alloy chain wheel seat fixing because of chucking power excessive, make it yielding, and this fixed form can have influence on the outer surface processing of chain pulley seat, the processing of whole chain pulley seat outer surface smoother can not be realized, need constantly to adjust clip position, production efficiency is low, and yield rate is low.Therefore, need a kind of durable, Stability Analysis of Structures, the structure little to workpiece damage replaces scroll chuck.
Summary of the invention
The invention is intended to provide a kind of inner circle hole workpiece clamping device with new structure, durable with what meet to fixture in conventional inner circle hole machined, Stability Analysis of Structures, to instructions for uses such as workpiece damage are little.
For achieving the above object, there is provided following basic technology scheme: the clamping device being applicable to inner circle hole workpiece, comprise frame, clamping device, drive unit, wherein said drive unit comprises depression bar, spring, gland, wherein said depression bar is positioned at the circular channel that described frame is provided with, described gland is connected with above depression bar, under the opening direction of described gland, described frame is provided with a spring supporting platform, described spring is located between gland and spring supporting platform, it is characterized in that: described gland outer peripheral face is provided with a pair otic placode relatively, two described otic placodes are respectively provided with a round boss, described clamping device comprises two and is oppositely arranged grip block, be articulated with below described grip block in frame, jaw is provided with above grip block, grip block is also provided with a bar shape trench hole, the different bar shape trench holes be positioned on two described grip blocks are arranged symmetrically with, and there is certain angle of inclination.
Adopt technique scheme, depression bar under the reaction force of spring away from spring supporting platform, depression bar otic placode tell a lie can round boss be placed in the bar shape trench hole on grip block, and to be positioned at this moment above slotted eye, be grip block be inward collapsible, inner circle hole workpiece is placed on jaw; Promote depression bar, depression bar drives boss to move, and boss slides in bar shape trench hole, drives grip block to rotate, outwards opens, realize the clamping of workpiece.This mechanism structure simple and stable, node is few, so durable, because the tensile force by jaw controls by the thrust of depression bar, so can not because power is excessive disfiguring workpiece.
Further optimization to base case: described drive unit also comprises a tapered shaft, one end of described tapered shaft is wedge shape, the passage adapted with tapered shaft that tapered shaft is positioned at that described frame is provided with, described tapered shaft is arranged vertically within described depression bar, the below of described depression bar has additional piston, also be provided with a wedged hole below depression bar, the wedge-shaped part potential energy of described tapered shaft is enough in this wedged hole.The setting of tapered shaft, depression bar can be driven to move by laterally promoting tapered shaft, more convenient to operate, the setting of piston decreases the frictional force between mechanism kinematic, more laborsaving.
Further optimization to base case: be provided with an adjusting nut above described depression bar, described gland is between described adjusting nut and described spring supporting platform.Turn adjusting nut, the initial position of restriction gland, regulates the opening and closing degree between jaw, to be applicable to the workpiece of different inner circle hole size.
Further optimization to base case: the surplus of certain altitude is left in the below of the depression bar passage that described piston and described frame are provided with.Leaving certain altitude surplus is avoid the movement of the accumulation of air in surplus to piston to cause difficulty, operates more laborsaving.
Further optimization to base case: in described frame, the passage two ends of tapered shaft are respectively equipped with large and small end cap, be wherein positioned at described wedge away from wedge shape one end for large end cap, described large end cap is provided with a hole passed for tapered shaft.The setting of large end cap is the distance extending tapered shaft passage, avoids the access portal place of tapered shaft to frame to cause damage; A sealing function is played in the setting of small end cover, avoids entering granule in passage, causes additional injuries to internal mechanism.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
