Abstract
The two-stage driving self-centering double scroll chuck consists of chuck body, inner wire, outer wire, rotating ring at the outer edge of the outer wire, linked bevel gear mounted to the rotating ring, inner claw, outer claw, driving bevel gear mounted on the outer edge of the chuck body and connecting disc. The inner wire is connected to a bevel gear, the outer wire has bevel teeth towards the driving bevel gear, the bevel tooth and the driving bevel gear are meshed with the linked bevel gear, and the rotating ring has bevel teeth meshes with the bevel gear. The chuck is used for clamping thin-walled turned workpiece with less deformation. When workpiece is loaded or unloaded, the crank will produce no shift and the operation is smooth.
Description
The present invention relates to the two scroll chucks of a kind of self-centering.
The existing chuck clamping thin-wall workpiece that is used for lathe turning processing usefulness often deforms because thickness of workpiece is little, the crudy of workpiece is affected, even causes defective.
The purpose of this invention is to provide a kind of processing thin-walled workpiece of turning that is used for, holding workpiece is difficult for deforming, the two-stage driving self-centering double scroll chuck that workpiece turning crudy is easy to guarantee.
Two-stage driving self-centering double scroll chuck by be evenly equipped with three radial grooves on the card and have the change that is shaped on, the outer parcel of direction opposite helical tooth, interior claw, outer claw identical on the tooth pitch helical tooth such as being shaped on the whole chuck body that connects cantilevered axle, the card and the whole interior parcel that is connected bevel gear, card being arranged, is loaded on outer parcel outer rim place, be loaded on the interlock bevel gear in the change with interior parcel helical tooth tooth pitch, driving bevel gear and the terminal pad that is loaded on the chuck body outer rim constitutes, interior parcel is loaded on the chuck body wall suspending axis, and outer parcel is sleeved on the interior parcel.Outer parcel is shaped on the umbrella teeth on the card of interior parcel bevel gear, umbrella teeth, interior parcel bevel gear and the engagement of interlock bevel gear.Change is shaped on the umbrella teeth on one side ring surface, umbrella teeth and the engagement of driving bevel gear.Inside and outside claw is fastened on the inside and outside claw slide that is loaded in the chuck body chute, inside and outside claw slide cooperates with the transmission of inside and outside parcel screw thread, inside and outside parcel rotates, inside and outside claw slide drive the lower edge slideway do mutually near or workpiece clamped or unclamp away from slippage.
In order to eliminate the eccentric adverse effect of the inside and outside circle of the preceding workpiece of workpiece turning processing to turning processing, further improving of two-stage driving self-centering double scroll chuck be, in adopting workpiece during circle clamping location outside the claw clamping face be provided with elastomer with certain rigidity; The claw clamping face is provided with the elastomer with certain rigidity in when adopting excircle of workpiece clamping location.
Two-stage driving self-centering double scroll chuck is used for thin-wall workpiece turning and adds that distortion free takes place after the piece-holder in man-hour, thereby has guaranteed the turning crudy.Drive bevel gear when gripper chuck, the part of knocking off rotation crank and be not moved, thereby manipulate no any discomfort sensation.
Accompanying drawing is one embodiment of the present of invention, further specifies the present invention below in conjunction with embodiment.
Fig. 1 is the two-stage driving self-centering double scroll chuck structure chart.
Fig. 2 is the A-A profile of Fig. 1.
As shown in the figure, two-stage driving self-centering double scroll chuck is connected with the chuck body (1) of cantilevered axle (15) by being evenly equipped with three radial grooves (3) and integral body on the card, tooth pitch helical tooth and integral body such as be shaped on the card and be connected with the interior parcel (18) of bevel gear (19), be shaped on the outer parcel (21) of tooth pitch and interior parcel helical tooth tooth pitch equidirectional opposite helical tooth on the card, be loaded on the change (20) at outer parcel outer rim place, be loaded on the interlock bevel gear (10) in the change, interior claw (8), outer claw (5), the terminal pad (16) that is loaded on the driving bevel gear (11) that has crank slot (12) on the chuck body outer rim and connects with chuck body constitutes, interior parcel is loaded on the cantilevered axle of chuck body by duplex bearing (17), and outer parcel is sleeved on the interior parcel.Outer parcel is shaped on the umbrella teeth on the card of interior parcel bevel gear, umbrella teeth, interior parcel bevel gear and the engagement of interlock bevel gear.Change is shaped on the umbrella teeth on one side ring surface, umbrella teeth and the engagement of driving bevel gear.Interior claw, outer claw are fastened on the interior claw slide (7) and outer claw slide (4) that is loaded in the disk body chute by securing member (9), (6), inside and outside claw slide cooperates with the transmission of inside and outside parcel screw thread, inside and outside parcel rotates, inside and outside claw slide drive inside and outside claw along chute do mutually near or workpiece clamped or unclamp away from slippage.Inside and outside claw acted on the power equal and opposite in direction on the workpiece when chuck clamped workpiece, and direction is opposite, so workpiece is difficult for deforming.Clamping or when unclamping workpiece with crank rotating drive bevel gear, bevel gear drives change and drives inside and outside parcel and rotate the crank position and be not moved, so the no any discomfort of operation is felt.Locate with excircle of workpiece during diagram chuck holding workpiece, be equipped with the elastomer (2) that spring leaf is made on the interior claw clamping face.(13) be dottle pin, (14) are positioning sleeve.
Claims (3)
1, a kind of two-stage driving self-centering double scroll chuck, it is characterized in that by being evenly equipped with three radial grooves and the whole chuck body that is connected with cantilevered axle on the card, tooth pitch helical tooth and the whole interior parcel that is connected with bevel gear such as be shaped on the card, be shaped on identical on the card with interior parcel helical tooth tooth pitch, the outer parcel of direction opposite helical tooth, interior claw, outer claw, be loaded on the change at outer parcel outer rim place, be loaded on the interlock bevel gear in the change, the driving bevel gear and the terminal pad that are loaded on the chuck body outer rim constitute, interior parcel is loaded on the chuck body cantilevered axle, outer parcel is sleeved on the interior parcel, outer parcel is shaped on the umbrella teeth on the card of interior parcel bevel gear, the umbrella teeth, interior parcel bevel gear and the engagement of interlock bevel gear, change is shaped on the umbrella teeth on one side ring surface, umbrella teeth and the engagement of driving umbrella wheel, in, outer claw be fastened on be loaded in the chuck body chute in, on the outer claw slide, in, outer claw slide with in, outer parcel screw thread transmission cooperates.
2, by the described two-stage driving self-centering double scroll chuck of claim 1, it is characterized in that being equipped with elastomer on the outer claw clamping face.
3,, be equipped with elastomer on the claw clamping face in it is characterized in that by the described two-stage driving self-centering double scroll chuck of claim 1.
