Description
Technical field
The utility model relates to and drilling or the process technology of boring machine, is specifically related to one and cuts escape frock.
Background technology
Usually some workpiece needs to process escape, as tapping in the hole got out, in order to make tap to the bottom in hole, needs at the bottom of hole, process a circle escape.The existing frock for cutting escape, normally after having bored hole, directly adopts cutter to cut out a circle escape in the bottom in hole, due to cutter cut escape time, axially easily produce disturbance, grooving action is unstable, and quality of notch is poor.
Utility model content
The utility model provides one to cut escape frock, to solve the axially easily disturbance when grooving of existing cutter, the problem of quality of notch difference.
This programme is as follows: cut escape frock, comprise grooving guide rod, advance and retreat cutter threaded cap and guide rod fairlead, grooving guide rod comprises large-diameter rod section and path bar section, path bar section and advance and retreat cutter threaded cap empty set, advance and retreat cutter threaded cap has stair-stepping first inner circle and the second inner circle, between first inner circle and path bar section, thrust bearing is housed, second inner circle is provided with internal thread, guide rod fairlead inner circle and large-diameter rod section fit, the cylindrical on guide rod fairlead top is provided with external screw thread, advance and retreat cutter threaded cap is threaded with the top of guide rod fairlead, grooving guide rod has the first pilot hole along its axis and the second pilot hole radially, the hollow push rod of feed is provided with in the first pilot hole, one end of the hollow push rod of feed can offset with thrust bearing, the other end is with top, necking cutter holder is provided with in the second pilot hole, one end of necking cutter holder is provided with inclined-plane, the other end is provided with cutter head, the top inclined-plane that withstands makes necking cutter holder radial feed, necking cutter holder is provided with back-moving spring.
During work, the main shaft of the path shaft part of grooving guide rod and boring machine or drilling machine connects.
This programme operation principle is as follows: grooving guide rod rotates in hole, after grooving guide rod axial depth puts in place, advance and retreat cutter threaded cap engages with guide rod fairlead external screw thread, rotate advance and retreat cutter threaded cap, the thrust bearing being positioned at advance and retreat cutter threaded cap withstands the hollow push rod of feed, the hollow push rod of feed moves down, the top inclined-plane withstanding necking cutter holder of the hollow push rod of feed, necking cutter holder is forced to move radially grooving, because grooving guide rod is rotate all the time, therefore, necking cutter holder can be driven to rotate and to cut out a circle escape.After grooving, screw out advance and retreat cutter threaded cap, under the effect of back-moving spring, necking cutter holder resets, and promotes grooving guide rod, completes grooving.
The utility model to have the effect of guiding due to guide rod fairlead to grooving guide rod, grooving guide rod has the effect of guiding to necking cutter holder, therefore can guarantee the stability of cutter head when grooving, can improve quality of notch.
Further, be provided with a circle boss at the top cylindrical of guide rod fairlead, the lower surface of boss can offset with work pieces process face.The lower surface of boss has the effect limiting grooving guide rod feeding depth, and when namely boss lower surface and work pieces process face offset, grooving guide rod shaft puts in place to feeding, and the precession distance of boss upper surface to advance and retreat cutter threaded cap has spacing effect.
Further, also comprise the cutter head degree of depth limiting plate being arranged on large-diameter rod section side, cutter head degree of depth limiting plate is connected with large-diameter rod section by trip bolt.Cutter head limiting plate limits the cutting groove depth of cutter head.
Further, the axis along necking cutter holder has storage tank, and back-moving spring is arranged in storage tank, and one end and the cutter head degree of depth limiting plate of back-moving spring offset, and the bottom land of the other end and storage tank offsets.Utilize cutter head limiting plate to hold out against back-moving spring, structure is simpler.
Accompanying drawing explanation
