Abstract
The utility model relates to a novel dovetail type comb-shape slotting cutter clamp knife device which comprises a knife frame ram; the dovetail type comb type slotting cutter clamp knife device is characterized in that the knife frame ram is provided with a groove, the groove is internally provided with a compacting block, the external lateral surface of the compaction block and one end of the side face of the groove are compacted, and the inner side face of the compaction block, the side face of the other end of the groove and the bottom surface of the groove combine a concurrent structure with a slotting cutter dovetail shape part; and the upper and lower end faces of the knife frame ram are respectively fixedly provided with a mounting plate and a supporting plate, the mounting plate is provided with a screw rod in a penetrating manner, and the lower part of the screw rod is provided with a press plate which is contacted with the upper end face of a slotting cutter. The clamp knife device realizes cutter transverse rapid positioning through a dovetail conjugation structure, does not needs to adopt a tool setting gauge to carry out tool setting, omits the tool setting time when the cutter is reground after installation, and the resetting precision of the cutter is ensured; in addition, the cutter is compacted in a transverse and longitudinal manner, the stability of cutter setting is improved, and the cutter thickness is increased and cutting edges can be arranged on the two sides of the cutter; and on the one hand, the service life of the cutter is prolonged, the regrinding times are increased, on the other hand, the tool sharpening can use on two faces in a primary manner, thus being contributed to improving the machining efficiency.
Description
Technical field
The utility model relates to the fixture of pinion cutter, particularly dovetail type pectination pinion cutter knife-clamping device.
Background technology
In the prior art, used pectination pinion cutter is fastenedly connected with screw and knife rest ram during the processing sector gear, and its locating surface is perpendicular to the cutter hub end face of the flank of tooth.When after pinion cutter is with blunt sharpening, installing and using once more; For guaranteeing that pinion cutter profile of tooth center line and work centre line are in same plane; Need carry out careful tool setting with special-purpose tool setting rule, treat just can process when tool-tooth profile center line and work centre line are in the same plane.But when using special-purpose tool setting rule to carry out centering, generally differentiate with eyes, cause the repetitive positioning accuracy of cutter low, the tool setting adjustment time is long, thereby influences workpiece processing efficient and machining accuracy.In addition, because cutter is only vertically being fixed, its stable installation property is poor, and cutter thickness is less, is generally about 25mm, when the thickness of its sharpening has only the 10mm left and right sides, will scrap, so cutter life is shorter.
Summary of the invention
The utility model provides a kind of cutter repetitive positioning accuracy of guaranteeing for solving the technical problem that exists in the known technology, cancellation tool setting adjustment time, the dovetail type pectination pinion cutter knife-clamping device of raising cutter stable installation property.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
Dovetail type pectination pinion cutter knife-clamping device; Comprise the knife rest ram; It is characterized in that: be shaped on groove on the said knife rest ram leading flank, in the said groove compact heap be installed, said compact heap lateral surface and groove one end side surface compress; Said compact heap medial surface, groove other end side and groove floor are combined into and the corresponding to structure of pinion cutter dovetail shaped part; Said knife rest ram upper surface and lower surface are fixed with gripper shoe and supporting plate respectively, are coated with screw rod on the said gripper shoe, and said screw rod bottom is provided with and the contacted pressing plate in pinion cutter upper surface.
The technical scheme that the utility model can also be taked is:
Said compact heap lateral surface is perpendicular to its front and back sides.
Said compact heap lateral surface and its medial surface are symmetrical set.
Advantage and the good effect that the utlity model has are:
Above-mentioned knife-clamping device is compared with prior art realized laterally locating fast of cutter through the dovetail fit structure, needn't adopt special-purpose tool setting rule to carry out tool setting; Cancelled the tool setting adjustment time when cutter is refaced the back installation; Guarantee the cutter repetitive positioning accuracy, in addition, because cutter is all compacted at transverse and longitudinal; Improve the cutter mounting stability, can increase cutter thickness and the cutter two sides is all processed cutting edge.Improve cutter life and the increase number of times of refacing so on the one hand, sharpening once can two-sidedly use on the other hand, helps improving working (machining) efficiency.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is the B-B cutaway view of Fig. 1.
Among the figure: 1, knife rest ram; 1-1, groove; 2, compact heap; 2-1, lateral surface; 2-2, medial surface; 3, gripper shoe; 4, supporting plate; 5, screw rod; 6, pressing plate; 7, workpiece.
The specific embodiment
For further understanding summary of the invention, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:
See also Fig. 1-3; Dovetail type pectination pinion cutter knife-clamping device; Comprise knife rest ram 1, be shaped on groove 1-1 on the said knife rest ram leading flank, be fixed with compact heap 2 in the said groove; Said compact heap lateral surface 2-1 and groove one end side surface compress, and said compact heap medial surface 2-2, groove other end side and groove floor are combined into and the corresponding to structure of pinion cutter dovetail shaped part.Said knife rest ram upper surface and lower surface are fixed with gripper shoe 3 and supporting plate 4 respectively, are coated with screw rod 5 on the said gripper shoe, and said screw rod bottom is provided with and the contacted pressing plate 6 in pinion cutter upper surface.Above-mentioned compact heap is installed in the groove through screw is detachable; Above-mentioned gripper shoe and supporting plate can be welded on the knife rest ram, also can be installed on the knife rest ram through screw is detachable.
Above-mentioned compact heap lateral surface can adopt faces structure directly, and promptly lateral surface is vertical with front and back sides.Adopt this structure, the side of matching on the groove should be mutually to be faced directly; The compact heap lateral surface also can adopt and the symmetrically arranged ramp structure of its medial surface.Adopt this structure, the groove two sides are parallel surface.
When using above-mentioned knife-clamping device to fix pinion cutter; At first the pinion cutter dovetail shaped is partly placed in the groove of knife rest ram; Make pinion cutter be supported on the supporting plate and alignd with the groove corresponding side surface in dovetail shaped part one side; Then compact heap is inserted in the space of pinion cutter and the formation of groove other end side, with screw compact heap is fixed on the knife rest ram, thereby realizes the cutter located lateral and compress.After pinion cutter laterally compresses, with the pressing plate end face that is placed on it, be rotated down screw rod then, the screw rod lower end is pressed on the pressing plate, thereby realizes that cutter vertically is fixed.
