Abstract
Description
Claims (1)
- null1. the helical gear organisation of working that can flexibly limit up and down motion,For using when processing blank (85),Comprising: pedestal (3)、Rotatable inner thread piece (1)、External thread piece (2) and columned Workpiece carrier part (8),Wherein,Rotatable inner thread piece (1) includes cylindrical portion (11) and lower chambers portion (12),Described lower chambers portion (12) passes through bearing arrangement (13) and pedestal (3) circumference can rotate and axial restraint ground is connected,External thread piece (2) is cylindric,It is provided with external screw thread on its outer circumference surface to engage with the female thread in described upper cylindrical portion (11),Pedestal (3) is provided with cavity (31),Cavity (31) has top wall (32),Driving motor (4) is installed in described cavity (31),Motor (4) is driven to be connected with the lower end of the first axle (5),Described first axle (5) is through the left-hand portion of described top wall (32),And on the section that described first axle (5) is positioned at top wall (32) top, it has been fixedly mounted the first gear wheel (51) and the first little gear (52) the most successively,The inside circumference face of described lower chambers portion (12) is fixedly installed ring gear (139),First gear wheel (51) engages with described ring gear (139),Make to drive motor (4) that described rotatable inner thread piece (1) when rotating, can be driven to rotate relative to pedestal (3),The cylindric extension in the left side downwardly extended (21) it is fixedly disposed at the bottom end face left-hand portion of described external thread piece (2),The top of the first axle (5) is inserted in the cylindric extension in a described left side (21),And extension cylindric with a described left side (21) can coordinate rotationally;Described columned Workpiece carrier part (8) all overlaps with the axial line of external thread piece (2) and described upper cylindrical portion (11), its upper end is provided with blank clamping structure, middle part, lower end is fixedly disposed middle circle column extension (81) downwardly extended, the bottom of described columned Workpiece carrier part (8) is connected with external thread piece (2) by lower bearing (83), top is connected with ring-type capping (84) by upper bearing (metal) (86), described ring-type capping (84) is fixed with external thread piece (2), thus, described columned Workpiece carrier part (8) can rotate relative to described external thread piece (2);Second axle (6) is installed the middle part axial restraint of described top wall (32), the lower end of described second axle (6) is connected with described top wall (32), top is inserted in described middle circle column extension (81), and the axial line of described second axle (6) overlaps with the axial line of described columned Workpiece carrier part (8), and described second axle (6) all can coordinate rotationally with described top wall (32) and described middle circle column extension (81);Being installed with second largest gear (61) and two pinion (62) on described second axle (6) the most successively, second largest gear (61) engages with the first little gear (52);Described top wall (32) is provided with the 3rd axle (7) on the right side of described second axle (6) with going back axial restraint, the lower end of described 3rd axle (7) is connected with described top wall (32), top is inserted in the blind hole in the right side wall being positioned at described external thread piece (2) so that described 3rd axle (7) all can coordinate rotationally with described top wall (32) and described blind hole;Being installed with the third-largest gear (71) and third pinion (72) on described 3rd axle (7) the most successively, the third-largest gear (71) engages with two pinion (62);Third pinion (72) is cylindric;Being installed with the fourth-largest gear (82) on the outer circumference surface of described middle circle column extension (81), the fourth-largest gear (82) engages with described third pinion (72);The upper end of described third pinion (72) is provided with elastic spacing ring (722), and lower end is provided with lower elastic spacing ring (721);Thus, under described external thread piece (2) positions while described first axle (5) and described 3rd axle (7) non-rotatable, when described driving motor (4) rotates, described upper cylindrical portion (11) drives external thread piece (2) to move up and down, thus drives described columned Workpiece carrier part (8) and blank (85) to move up and down relative to pedestal (3);Meanwhile, driving motor (4) can also pass through described gear (51,52,61,62,71,72,82) drives described columned Workpiece carrier part (8) and blank (85) to rotate relative to pedestal (3);And then, under the shear action of cutter, it is possible to process spiral alveolar on blank (85);When described columned Workpiece carrier part (8) and blank (85) rise to extreme higher position, the most still keeping between top extension cylindric with a described left side (21) of described first axle (5), between the top of described second axle (6) and described middle circle column extension (81), between top and the described blind hole of described 3rd axle (7) coordinating rotationally, described the fourth-largest gear (82) still keeps engaging with the described third pinion (72) of cylindrical shape;When described external thread piece (2) moves up and down, described upper elastic spacing ring (722) can flexibly limit described the fourth-largest gear (82) and exceed moving upward of the upper limit relative to described third pinion (72);Described lower elastic spacing ring (721) can flexibly limit described the fourth-largest gear (82) and exceed moving downward of lower limit relative to described third pinion (72), it is possible to flexibly limit the up and down motion in described helical gear organisation of working.
