Detailed description of the invention
Be below specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As shown in Figures 1 to 7, this rotary pneumatic jaw arrangement comprises the swivel mount 2 of rotary cylinder 1 and rectangular triangular prism shape, wherein rotary cylinder 1 is fixedly arranged on the prism of swivel mount 2, two right-angled side faces of swivel mount 2 are separately installed with the first gas pawl 4 and the second gas pawl 5, rotary cylinder 1 fastens and has horizontally turned axle 11, horizontal axle 11 one end of turning to be interted on swivel mount 2 and swivel mount 2 can move radially along horizontal axle 11 of turning.
When using this rotary pneumatic jaw arrangement, need guarantee two gas pawl in rotation, namely be in horizontally disposed first gas pawl 4 and just can be positioned at the position being originally in the second gas pawl 5 vertically arranged after rotation, and the second gas pawl 5 being originally in vertically setting just can be positioned at the position being originally in horizontally disposed first gas pawl 4 after rotation, that is the first gas pawl 4 and the second gas pawl 5 can replace respective position in rotation alternation procedure, so just can ensure that two gas pawls are in conversion alternation procedure, be converted to the axial line being in horizontally disposed gas pawl superimposed with the axial line of main shaft all the time.
And in use, owing to there is mismachining tolerance and alignment error, being difficult to guarantee first gas pawl 4 and the second gas pawl 5 in rotation alternation procedure can replace respective position, that causes this problem is mainly present in following situations:
Spacing between the axial line of the second gas pawl 5 and the rotation centerline of swivel mount 2 is greater than or less than the spacing between the axial line of the first gas pawl 4 and the rotation centerline of swivel mount 2, this will cause the second gas pawl 5 to offset originally the first gas pawl 4 to the left or to the right and be in horizontally disposed position turning to position when being horizontally disposed with, thus make the axial line of the second gas pawl 5 and spindle axis line not on the same line, cause the second gas pawl 5 workpiece cannot be fed through main shaft place accurately;
When this situation occurs, be fixedly mounted on swivel mount 2 in the first gas pawl 4, therefore the second position of gas pawl 5 on swivel mount 2 determine two gas pawls conversion alternation procedure in position whether can be consistent, by adjustment swivel mount 2 along horizontal radial direction of turning axle 11, the spacing between the axial line of the second gas pawl 5 and the rotation centerline of swivel mount 2 is made to be equal to spacing between the axial line of the first gas pawl 4 and the rotation centerline of swivel mount 2, thus the axial line of the second gas pawl 5 turning to horizontal level is overlapped with the axial line of main shaft, like this when the first gas pawl 4 and the second gas pawl 5 are when changing alternately, first gas pawl 4 and the second gas pawl 5 level and vertical position superimposed all the time.
Swivel mount 2 offers installing hole 23 and there is a limited block 24 in installing hole 23, limited block 24 offers the bar hole 25 communicated with installing hole 23, horizontal axle 11 one end of turning is positioned at installing hole 23 and is connected through bar hole 25 and swivel mount 2 by screw, swivel mount 2 liang of right-angled side faces also offer and is symmetrical arranged and the cross-drilled hole 26 communicated with installing hole 23, in cross-drilled hole 26, be equipped with lateral pin 12 and lateral pin 12 the inner is tight against to lean against and horizontally turns on axle 11, wherein the axial line of cross-drilled hole 26 is perpendicular to the axial line of installing hole 23.First need ensure during use that the first gas pawl 4 rotates to the axial line of the first gas pawl 4 during horizontal level to overlap with the axial line of main shaft, and in actual use, owing to there is mismachining tolerance and alignment error, the rotation centerline of swivel mount 2 and the rotation centerline of rotary cylinder 1 there will be nonoverlapping situation, the axial line of the first gas pawl 4 is caused not overlap with the axial line of main shaft, because horizontal axle 11 of turning is fixedly arranged on rotary cylinder 1, therefore the horizontal axial line turning axle 11 is the rotation centerline of rotary cylinder 1, by adjusting the horizontal lateral pin 12 turning axle 11 both sides, swivel mount 2 can be made to move along transverse axis axial direction, thus make the rotation centerline of swivel mount 2 and the horizontal axial line turning axle 11, ensure that and to overlap with the axial line of main shaft at the axial line of first timing first gas pawl 4.
Further, rotary cylinder 1 has in circular rotating part 1a, and rotating part 1a outer face radially offers the stopper slot 1b running through rotating part 1a, the prism of swivel mount 2 has limiting section 27 and limiting section 27 is plugged in stopper slot 1b.This structural design makes when adjusting the position of swivel mount 2 on rotary cylinder 1, and swivel mount 2 can only move linearly along stopper slot 1b.
Further, rotary cylinder 1 is provided with two limit bases 6, swivel mount 2 is provided with block 7, and block 7 can be resisted against on limit base 6 when swivel mount 2 circumference is rotated.Because two gas pawls are mounted in two right-angled side faces of swivel mount 2, in each conversion alternation procedure, must ensure that two gas pawls can be in level and vertical state respectively relative to swivel mount 2, that is must ensure that the gas pawl being in level aligns with spindle axis, otherwise there will be swivel mount 2 rotate the gas pawl that excessively makes to be in level and spindle axis unjustified, cause the problem that workpiece accurately cannot be fed through main shaft place.By coordinating between two limit bases 6 on rotary cylinder 1 and the block 7 on swivel mount 2, rotational angle when swivel mount 2 circumference is rotated can be controlled, namely all 90 degree can only be rotated when the positive and negative rotation of swivel mount 2, thus ensure that two gas pawls can be in level and vertical state respectively after swivel mount 2 rotates, the gas pawl being wherein in level can align with spindle axis.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
