Portable tool grinder

The utility model relates to a kind of portable cutlery mill that is used for the metal cutting tool sharpening, especially for garden dish milling cutter, metal saw, face and side cutter, garden post milling cutter, slotting cutter, chain slotting cutter, gear hob and car, insert, cutters such as boring, plane sharpening, belong to attaching of metal machining facility.

Mostly the sharpening of metal current cutting tool is with artificial hand operated cutter sharpening on abrasive machine, and mostly complicated class sharpenings such as garden sheet shape milling cutter of shape are carrying out on the multipurpose instrument (tool) mill or on the special-purpose machining tool.As: the patent of invention of Japanese Tokico Ltd application, application number CN86101840A, a kind of spiral cutter working apparatus disclosed be one by the mobile working head with the screw-on cutter shape on September 24th, 1986, the wheel grinding milling cutter is installed, other has a calibration organisation of working to rotate screw-on cutter, this special purpose machine tool with electric-motor drive is suitable for the processing or the sharpening of screw-on cutter.The utility model patent of Harbin Institute of Technology's application, application number CN882139991, a kind of high-accuracy liquid diamond cutter grinder was disclosed on May 27th, 1989, diamond cutter is equipped with the base bearing of the hydrodynamic journal liquid polymers of electric-motor drive in elder generation, separate to be equipped with it and grind the dish finishing machine, be applicable to the sharpening of the diamond cutter that grinding precision is had relatively high expectations, the lathe that these are special-purpose, main deficiency is need be installed in fixedly in the workshop, lathe itself is suitable for the specificity requirement, the project organization complexity, involve great expense, only be applicable to the processing or the sharpening of single cutter.

Task of the present utility model provides a kind of portable instrument mill that is applicable to the multiple tool sharpening of metal processing, can attach at random as metal working machine tool, to multiple milling cutter, hobboing cutter and car, insert, the sharpening of cutters such as boring, plane.

Technical solution of the present utility model is at the last end dress of grinding wheel spindle (1) emery wheel (2), the other end is equipped with a friction pulley (3) made from big material of coefficient of friction such as rubber-like, this main shaft and two cover bearings (4,5) be contained in one vertical pivot (7) is arranged and adjust lifting or the level of the T oblique crank Z frame (6) of pivot angle with in the tube, in the vertical pivot sleeve that vertical pivot inserts with lower table (9) links to each other, this sleeve has a locking clip (10) that has the nut consubstantiality of adjusting the grinding wheel spindle lifting outward, the fixedly thimble seat (13) and the movable top needle stand (14) of chucking cutter are housed on upper table (12) face, be equipped with on the table top between two thimble seats and make by the chucking unidirectional rotating spring detent of cutter (15), there is the steerage gear (17) on a tooth bar (16) and the lower table this workbench side, adjusts upper table and slides in the rail groove of lower table.And lower table is laterally moved by handle (31).

The lifting of grinding wheel spindle or pivot angle adjustment are to reach the back by the position that the vertical pivot of adjusting T oblique crank Z frame inserts the vertical pivot sleeve to be locked on the vertical pivot sleeve (8) by a clip (10) that has chucking screw rod and nut spanner (18) and lifting nut (11), when further finely tuning the grinding wheel spindle lifting, rotate lifting screw (19), the T shape frame of drive grinding wheel spindle rises or falls.

Two top iron of upper table face, chucking is to have nut (20) and screw rod (19) to drive a rod member (21) that links to each other with thimble (14) on the live centre frame by the cutter of sharpening, hand screw (22) is to reaching chucking or loosening cutter (23), behind the cutter chucking, tooth bar (16) that can manual gear (17) transmission upper table slides it in the gauge play of lower table; Manual handle (31) laterally moves workbench.

For make by the sharpening cutter uniformly one by one tooth process, adorn a spring kayser (15) at the upper table face, can be unidirectional the processing of calibration sharpening.

The utility model has the advantages that simple in structurely, volume is little, and is in light weight, contacts with friction pulley with any one driving member that exposes of working machine, and can drive the grinding wheel spindle revolution, carries out sharpening work.Be specially adapted to the reconditioning of cutter, very light, easily to move, it is very convenient that precision is only carried out sharpening at a general cutter that requires, and saves the operation that the special purpose machine tool place arranges sharpening.

With accompanying drawing the utility model further is illustrated below.

Fig. 1 is a structure organigram of the present utility model

Fig. 2 is that the right side of Fig. 1 represents that to view the upper table chucking is by the cutter thimble structure organigram of sharpening

Fig. 3 is the clip nut structure figure of locking vertical pivot sleeve

Fig. 4 is the spring detent structure chart that is loaded on the upper table face

An end that represents main shaft (1) in Fig. 1 has emery wheel (2) and the other end that friction pulley (3) is arranged, be loaded on the T oblique crank Z frame (6) by single-row garden cone roller bearing (4) and (5), vertical pivot (7) inserts the vertical pivot sleeve (8) that links to each other with lower table, lock by clip (10), move handle (18) location, rotating screw bolt (19) is at the liter of nut (11) or fall and drive T oblique crank Z frame (6), adjust the liter of grinding wheel spindle or fall, on upper table (12) table top spring kayser (15) is arranged, make captured cutter (23) unidirectional rotary, upper table (12) side has is equipped with manual gear (17) and tooth bar (16) engagement on tooth bar (16) lower table (9), move handle (24) upper table (12) is slided in the rail groove of lower table (9).
