Abstract
The invention discloses a pipe hole grooving cutter being a machining cutter; and the pipe hole grooving cutter consists of a hexagonal head bolt, a cutter bar, a positioning sleeve, a cover, a thrust ball bearing, a grooving conical end fastening screw, an eccentric sleeve, a pin, a transmission tail base, a cylinder spiral compression spring, a steel ball, a key and a blade. One end of the eccentric sleeve is positioned in an inner cavity of the transmission tail base, and the cylinder spiral compression spring is added between the two and fixed by using the key; the other end of the eccentric sleeve is connected with the thrust ball bearing and the positioning sleeve in sequence through threads; one end of the cutter bar fixedly clamps the blade by using the hexagonal head bolt, and the other end is positioned in the inner cavity of the eccentric sleeve; the steel ball is positioned between the cutter bar and the eccentric sleeve; the pin wholly connects the cutter bar, the eccentric sleeve and the transmission tail base to penetrate in the cover; and the cover and the eccentric sleeve are fastened by the grooving conical end fastening screw. The grooving cutter is simple in structure, low in manufacturing cost, precise in grooving position, strong controllability of grooving depth, stable and reliable in performance, wide in application range, strong in popularity and capable of being assembled in rocker arm drilling machines with various model numbers.
Description
Technical field:
The invention relates to the paddle-tumble cutter that a kind of machining pore inner groovy uses, be applicable to the grooving of the pore inside that mechanical processing industry can not be completed by the processing mode such as car, milling, be particularly useful for the paddle-tumble of strength and buckling groove after chemical machinery industry, refrigeration industry and heat exchange industry tubular heat exchanger tube sheet hole drilling.
Background technology:
Before this, the inner paddle-tumble of pore is completed by simple and easy repacking cutter usually, and efficiency is low, in pore, location, paddle-tumble position is inaccurate, and grooving is deep mixed, and grooving quality cannot meet the requirement of subsequent operation, seriously constrain product quality and production efficiency, even bring heavy economic losses to enterprise.
Summary of the invention:
In order to solve the problem, the invention provides a kind of pore paddle-tumble cutter, and this cutter is not only processed simply, long service life, and improves quality and the production efficiency of product, reduces production energy resource consumption and production cost.
The invention solves the technical scheme that its technical problem adopts: a kind of pore paddle-tumble cutter, it is characterized in that it bores end holding screw by hexagon-headed bolt, knife bar, positioning sleeve, overcoat, thrust ball bearing, fluting, eccentric bushing, pin, transmission tailstock, cylindroid helical-coil compression spring, steel ball, key, blade form.The eccentric bushing other end connects thrust ball bearing and positioning sleeve successively by screw thread, and the other end inserts transmission tailstock inner chamber, adds cylindroid helical-coil compression spring and utilizes key guide-localization to connect in the middle of both; Blade is installed fixing by knife bar one end hexagon-headed bolt, and the other end inserts eccentric bushing inner chamber, places steel ball between knife bar and eccentric bushing; Pin penetrates overcoat after knife bar, eccentric bushing and transmission tailstock are connected into entirety, and overcoat and eccentric bushing are slotted to bore and held holding screw fastening.
The invention structure is simple, cheap for manufacturing cost, stable and reliable for performance, applied widely, highly versatile, and can be fitted on each model radial drilling machine and be suitable for, the useful achievement obtained is as follows: positioning sleeve and blade distance is adjustable guarantees that grooving position is accurate; Positioning sleeve and pore small―gap suture coordinate that to guarantee into groove depth consistent; Pin slides and drives the radial feed having relatively rotated blade of eccentric bushing and knife bar in transmission tailstock; The elastic deformation of the cylindroid helical-coil compression spring in the middle of transmission tailstock and eccentric bushing realizes the reset after feeding.

1, hexagon-headed bolt, 2, knife bar, 3, positioning sleeve, 4, overcoat, 5, thrust ball bearing, 6, fluting cone end holding screw, 7, eccentric bushing, 8, pin, 9, transmission tailstock, 10, cylindroid helical-coil compression spring, 11, steel ball, 12, key, 13, blade.
Detailed description of the invention
Be described in detail below in conjunction with the optimum implementation of accompanying drawing to the invention.A kind of pore paddle-tumble cutter, it is made up of hexagon-headed bolt 1, knife bar 2, positioning sleeve 3, overcoat 4, thrust ball bearing 5, fluting cone end holding screw 6, eccentric bushing 7, pin 8, transmission tailstock 9, cylindroid helical-coil compression spring 10, steel ball 11, key 12, blade 13.Eccentric bushing 7 other end connects thrust ball bearing 5 and positioning sleeve 3 successively by screw thread, and the other end inserts transmission tailstock 9 inner chamber, adds cylindroid helical-coil compression spring 10 and utilizes key 12 guide-localization to connect in the middle of both; Blade 13 is installed fixing by knife bar 2 one end hexagon-headed bolt 1, and the other end inserts eccentric bushing 7 inner chamber, places steel ball 11 between knife bar 2 and eccentric bushing 7; Pin 8 penetrates overcoat 4 after knife bar 2, eccentric bushing 7 and transmission tailstock 9 are connected into entirety, and overcoat 4 holds holding screw 6 fastening with eccentric bushing 7 with slotting to bore.
During use, select suitable positioning sleeve 3 according to pore diameter, according to the blade 13 that the preparation of paddle-tumble size is applicable to, be assembled into a complete cutter, and by transmission tailstock 9 clamping on radial drilling machine main shaft.When blade 13 is fixed, also, adjustment blade 13 extension elongation is slightly less than positioning sleeve 3 external diameter, and blade and positioning sleeve distance meet paddle-tumble position dimension for cutting edge and eccentric bushing 7 wall thickness place homonymy.Positioning sleeve 3 inserts in pore and completes location, and transmission tailstock 9 drives eccentric bushing 7 by key 12, and eccentric bushing 7 drives knife bar to move in a circle with radial drill main shaft plane on thrust ball bearing 8 by pin 8.Boring handle by rotating arm makes main shaft press down transmission tailstock 9, transmission tailstock 9 passes through key 12 along the keyway slide downward on eccentric bushing 7, a pair counter-force is formed with the lifting force of positioning sleeve 3, pin 8 is slided along the spiral on transmission tailstock 9, knife bar 2 and eccentric bushing 7 is driven to produce relative rotation, blade 13 goes to from eccentric bushing 7 wall thickness side the radial feed completing blade the process of the thin side of wall, and the amount of feeding of blade is controlled by the scale in radial drill handle chassis.Pore paddle-tumble completes in the axially-movable and blade radial feed process of knife bar.
