Description
Technical field
The utility model relates to mechanical manufacturing field, is specifically related to a kind of lengthening fluted drill.
Background technology
Generally for bore depth and the diameter of bore elongated hole than l:d > 10, need to adopt gun drilling, but because elongated hole drilling cost is high, need special equipment, and common fluted drill be not suitable for processing slim hole, and common homemade lengthening fluted drill stress concentration point is all in spiral bit and lengthening handle junction, i.e. commissure, when after broken drill, the spiral bit of the transformation of the way will be stayed in workpiece and cannot be taken out, cause workpiece to be scrapped.
Utility model content
For the problems referred to above, technical problem to be solved in the utility model be to provide a kind of can processing slim hole, non-frangibility and easily take out the lengthening fluted drill of drill bit.
The utility model adopts following technical scheme:
The utility model comprises extension bar and transformation of the way spiral bit, and described extension bar comprises the Morse taper shank be connected with machine tool chief axis, the transition axis body that the elongated slot be arranged on Morse taper shank, one end are fixedly connected with Morse taper shank, the connection handle be fixedly connected with the transition axis body other end, the inner stopper being arranged on connection handle end and be arranged on the internal thread hole of inner stopper medial end; The location axis body that described transformation of the way spiral bit comprises fried dough twist drillstock, one end is fixedly connected with fried dough twist drillstock and be arranged on the screw thread axis body of locating the axis body other end; Described connection handle diameter is less than fluted drill shank diameter, described location axis body diameter is less than connection handle diameter, described thread spindle body diameter is less than location axis body diameter, described transition axis body diameter 1mm-2mm less of footpath, the end diameter of described screw thread axis body, described inner stopper and described location axis body interference fit, described internal thread hole is connected with screw thread axis body, and described fried dough twist drillstock and connection handle are by being welded to connect, and the weld bead height be welded to connect is not higher than connection handle diameter; Axiality≤0.05mm between described Morse taper shank, connection handle and fried dough twist drillstock.
The beneficial effects of the utility model are as follows:
By using the utility model at drilling machine, lathe or boring machine, depth drill processing slim hole can be substituted, eliminating processing slim hole special equipment, cost-saving, the utility model compact conformation, is easy to realize, meet the processing request of most elongated hole, eliminate customized depth drill; Stress concentration portion is transferred to transition axis body by commissure, avoid drill bit fracture in inside, hole and can not get, due to the axiality≤0.05mm between Morse taper shank, connection handle and fried dough twist drillstock, avoid out-of-balance force during boring, better prevent broken drill, employing is threaded and interference fit makes cutting force better be delivered to drill bit from lathe.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
fig. 2 is the structural representation of the utility model extension bar;
Fig. 3 is the structural representation of the utility model transformation of the way spiral bit.
In accompanying drawing: 1, extension bar; 2, spiral bit is changed a social system; 11, Morse taper shank; 12, elongated slot; 13, transition axis body; 14, connection handle; 15, internal thread hole; 16, inner stopper; 21, screw thread axis body; 22, axis body is located; 23, fried dough twist drillstock; 3, weld seam.
Detailed description of the invention
As Figure 1-3, the utility model comprises extension bar 1 and transformation of the way spiral bit 2, and described extension bar 1 comprises the Morse taper shank 11 be connected with machine tool chief axis, the transition axis body 13 that the elongated slot 12 be arranged on Morse taper shank 11, one end are fixedly connected with Morse taper shank 11, the connection handle 14 be fixedly connected with transition axis body 13 other end, the inner stopper 16 being arranged on connection handle 14 end and be arranged on the internal thread hole 15 of inner stopper 16 medial end; Described transformation of the way spiral bit 2, adopts the fluted drill of standard again to process obtained by the drillstock of its afterbody, the location axis body 22 that it comprises fried dough twist drillstock 23, one end is fixedly connected with fried dough twist drillstock 23 and be arranged on the screw thread axis body 21 of locating axis body 22 other end; Described connection handle 14 diameter is less than fried dough twist drillstock 23 diameter, described location axis body 22 diameter is less than connection handle 14 diameter, described screw thread axis body 21 external diameter is less than location axis body 22 diameter, described transition axis body 13 diameter 1mm-2mm less of the minor diameter of described screw thread axis body 21, transition axis body 13 is made to become stress concentration point, when cutting force is excessive, transition axis body 13 fractures at first.Described inner stopper 16 and described location axis body 22 interference fit, described internal thread hole 15 is connected with screw thread axis body 21, better cutting force is delivered to drill bit place; Described fried dough twist drillstock 23 and connection handle 14 are by being welded to connect, and described weld seam 3 is not higher than connection handle 14 diameter; Axiality≤0.05mm between described Morse taper shank 11, connection handle 14 and fried dough twist drillstock 23.
Morse taper shank 11 is arranged in machine tool chief axis, main shaft and elongated slot 12 are fixed by chock, during boring, first get out bullport with common fluted drill, then kollag is smeared, by main axis control 300r/min, when drilling at lengthening spiral bit, continuous filling cutting fluid, to reduce processing temperature.After processing certain depth, main shaft rotates pulls back, and takes out iron filings.Owing to being provided with stress concentration portion, thus drill bit is avoided to fracture at fluted drill and lengthening handle junction.
The above embodiment is only preferred embodiment of the present utility model, and is not the exhaustive of the feasible enforcement of the utility model.For persons skilled in the art, to any apparent change done by it under the prerequisite not deviating from the utility model principle and spirit, all should be contemplated as falling with within claims of the present utility model.
