Abstract
The utility model relates to a processing tool for pipe holes and expansion grooves, which belongs to the machine tool. The processing tool for pipe holes and expansion grooves comprises a cutter rod and a cutter head. The utility model is characterized in that a cutter body is connected with one end of the cutter rod by a wire pin. A bearing and a shim are connected with the stairway end face of the cutter body by a clamp ring. A core rod passes through a central hole of the cutter body and is connected with the cutter rod. The lower end of the core rod is provided with a diagonal rib. The cutter head is provided with a diagonal groove which is matched with the diagonal rib of the lower end of the core rod. The cutter head is arranged on the lower end of the core rod. The utility model has the advantages of easy assembly and disassembly, economy and practicality, and can ensure the proper alignment requirement of an expansion groove and a pipe hole. The utility model can better incarnate the characteristics of the radial drilling machine of flexible rotation and quick positioning. The working size precision and the smoothness of the expansion groove are high. The processing tool for pipe holes and expansion grooves can enhance efficiency for more than ten times.
Description
The utility model belongs to machine tool, relates generally to the cutter of working groove.
The bloated groove of the pore of prior art mostly adopts boring machine, milling machine or numerical control device and utilizes the moulding boring cutter or the processing of special milling cutter.Exist the process-cycle long, the cost height, cutter is easy to wear, frangibility, the labour intensity height, and also machining accuracy is difficult for guaranteeing.
The purpose of this utility model provides a kind of plain radial drilling machine that utilizes, and molding cutter is adopted in the location automatically, the bloated groove machining tool of the pore that production efficiency is high.
The utility model comprises knife bar and cutter head, it is characterized in that cutter hub is connected knife bar one end by the silk pin, bearing and pad are connected the ladder end face of cutter hub by snap ring, core bar is connected with knife bar by the centre bore of cutter hub, the core bar lower end is provided with diagonal bar, offer skewed slot on the cutter head and cooperate with the diagonal bar of core bar lower end, cutter head is installed in the core bar lower end.
Silk pin one end of the present utility model is positioned at the chute on the knife bar, between the ladder end face of knife bar end face and cutter hub endoporus spring is set.
The utility model is easy to loading and unloading, and is economical and practical, work step such as can finish smoothly that location, transmission, feed cutting, cutter reset, the axiality requirement of guarantee to expand groove and pore, and can embody preferably radial drilling machine rotate flexible, locate characteristics rapidly; Can process the bloated groove of different depth by changing pad.Cutter head is bumped in the cutter hub groove, helps strengthening the rigidity and the anti-impact force of cutter, makes that cutter is durable, cutting is strong, the groove accurate to dimension height, highly polished that expands, and improves work efficiency more than ten times, has very significantly effect.
The utility model is described in further detail below in conjunction with accompanying drawing:
Accompanying drawing is the structural representation of the utility model embodiment.
Among the figure, the 1st, knife bar, 2 pins, 3 springs, 4 core bars, 5 cutter hubs, 6 bearings, 7 are regulated pad, 8 snap rings, 9 cutter heads.
After each part is assembled together by figure, taper shank by knife bar 1 inserts in the spindle hole of drilling machine, the manipulation drilling machine is packed cutter hub 5 one ends that have cutter head 9 into to be needed in the hole of bloated groove, main shaft is rotated with certain speed, pull Handl eof drill press, drill press spindle is moved down, knife bar 1 drives core bar 4 and moves down, cutter head 9 is under the diagonal bar effect on the core bar 4, through feed, after the degree of depth that the bloated groove of arrival requires, pull Handl eof drill press and lift main shaft, cutter head 9 is return original position automatically, cutter is withdrawed from outside the hole, to the expand groove processing of next hole.Change the adjusting pad 7 of different-thickness, can regulate the position of the groove that expands.Silk pin 2 transmits torque, when the main shaft of drilling machine rotates, drives cutter hub 5 and rotates.Snap ring 8 will be regulated the ladder end that pad 7 and bearing 6 are fixed on cutter hub 5,3 bufferings of spring and reset response.
Claims (2)
1, the bloated groove machining tool of a kind of pore, comprise knife bar and cutter head, it is characterized in that cutter hub is connected knife bar one end by the silk pin, bearing and pad are connected the ladder end face of cutter hub by snap ring, core bar is connected with knife bar by the centre bore of cutter hub, the core bar lower end is provided with diagonal bar, offers skewed slot on the cutter head and cooperates with the diagonal bar of core bar lower end, and cutter head is installed in the core bar lower end.
