Abstract
The utility model discloses a hard alloy screw hole processing device capable of processing high precision hard alloy screw hole, comprising an electrode, wherein a fixation nail at one end of the electrode is arranged in an electrode grip and another end of the electrode is provided with an external screw mated with the screw hole to be processed and the electrode grip is arranged in a clamp seat and in screw fit and a gear is slidably arranged at the tail part of the electrode grip and the electrode grip is in spline fit with the gear and a rack hole is arranged at one side of the gear and racks are arranged in the rack hole to engage with the gear and the end of the electrode grip is provided with a retainer which is arranged at the outer side of the gear and fixed in the clamp seat. The processing device is suitable for processing hard alloy screw hole.
Description
Technical field
The utility model belongs to the manufacture field of carbide alloy, relates to a kind of device that is used for processing rigid alloy screwed hole.
Background technology
The application of carbide alloy is very extensive, as mould, cutter handle of a knife etc.Because China's thread tap generally adopts high-speed tool steel, hardness is HRC60～63, can not process the carbide alloy higher than its hardness, so adopt machining carbide alloy screwed hole by electric spark, in spark machined, general first machining screw bottom outlet on hard earlier, on the electric pulse lathe, use the method thread mill drilling of translation then with the electrode that has thread of minor diameter, the accuracy of thread that adopts above-mentioned electrode and processing method to process is not high, can't be used for the place in requirement high precision screw hole.
The utility model content
The purpose of this utility model is to provide a kind of machining device for hard alloy screwed holes that can process high-precision carbide alloy screwed hole.
For achieving the above object, the technical solution adopted in the utility model is: a kind of machining device for hard alloy screwed holes, comprise electrode, one end staple of electrode is arranged in the terminal clamp, the other end of described electrode is provided with the external screw thread that is complementary with screwed hole to be processed, described terminal clamp is arranged in the clamping fixture seat, and with the clamping fixture seat threaded engagement, the terminal clamp afterbody also slides and is provided with gear, and by spline fitted, a side of gear is provided with rack bore between terminal clamp and the gear, be provided with tooth bar in the rack bore, the rack and pinion engagement, the end of terminal clamp is arranged with back-up ring, and back-up ring is positioned at the outside of gear and is fixedly installed on clamping fixture seat.
The utility model has the advantages that: adopt said apparatus can on carbide alloy, process high-precision screwed hole.
Description of drawings
Fig. 1 is the structural representation of the utility model machining device for hard alloy screwed holes;
Fig. 2 is the vertical view of Fig. 1.
Among the figure: 1, electrode, 2, preceding lock-screw, 3, terminal clamp, 4, external screw thread, 5, clamping fixture seat, 6, gear, 7, spline, 8, rack bore, 9, tooth bar, 10, back-up ring, 11, the back lock-screw, 12, table top, 13, insulation board, 14, workpiece.
The specific embodiment
Be described in further detail below in conjunction with the structure and the course of work of accompanying drawing the utility model machining device for hard alloy screwed holes:
As Fig. 1, shown in Figure 2, a kind of machining device for hard alloy screwed holes, comprise electrode 1, one end of electrode 1 is arranged on the head of terminal clamp 3 by preceding lock-screw 2, the other end of electrode 1 is provided with the external screw thread 4 that is complementary with screwed hole to be processed, the middle part of described terminal clamp 3 and afterbody are arranged in the clamping fixture seat 5, and with clamping fixture seat 5 threaded engagement, the afterbody of terminal clamp 3 also slides and is provided with gear 6, cooperate by spline 7 between terminal clamp 3 and the gear 6, one side vertical direction of gear 6 is provided with rack bore 8, be provided with tooth bar 9 in the rack bore 8, tooth bar 9 and gear 6 engagements, the end of terminal clamp 3 is arranged with back-up ring 10, and back-up ring 10 is positioned at the outside of gear 6 and is fixed on clamping fixture seat 5 by back lock-screw 11.
The course of work of this machining device for hard alloy screwed holes is as follows: machining device for hard alloy screwed holes is installed on the table top 12 of electric pulse lathe, and tooth bar 9 is installed on the head of electric pulse lathe (not drawing among the figure), between machining device for hard alloy screwed holes and the table top 12 insulation board 13 is set, regulate the position of workpiece 14 then, make thread Pilot hole to be processed over against electrode 1, driving tooth bar 9 with the relief head moves down, gear 6 rotates under the transmission of tooth bar 9, gear 6 rotates terminal clamp 3 by spline 7, because gear 6 and clamping fixture seat 5 threaded engagement, so terminal clamp 3 under the rotation of gear 6 to anticlockwise, the thread Pilot hole that terminal clamp 3 screws in electrode 1 on the workpiece 14, this moment opening power, control electrode 1 discharge, the double thread bottom outlet carries out spark machined, controlling head then makes on the tooth bar 9 and moves, electrode 1 retreats thereupon, and the waste residue in the thread Pilot hole can be discharged, and circulation just can process high-precision screwed hole and so forth.
The utility model has the advantages that: adopt said apparatus and use electric discharge machining method to process high-precision screwed hole at carbide alloy.
