Description
Technical field
The utility model belongs to wheel hub tooling device, and in particular to a kind of hub drill attacks NPT1/2 " screw thread hole tools.
Background technology
At present, in wheel hub processing technology, usually wheel hub is placed on a fixture body, is fixedly clamped in Z3050 drilling machines
It bored on the side of square chest, attack NPT1/2 " threaded holes, not only fixture makes complicated, but also is difficult to ensure that the steady of position dimension
Qualitative and threaded hole size, operation is time-consuming and laborious, seriously affects productive temp, greatly reduces production efficiency.
The content of the invention
The purpose of this utility model is to provide a kind of hub drill, attack NPT1/2 " screw thread hole tools.The utility model positions
Reliably, accurately, it is simple in structure, it is easy to operate, substantially increase the processing efficiency of wheel hub.
The technical solution adopted in the utility model：A kind of hub drill attacks NPT1/2 " screw thread hole tools, it includes lathe worker
Make platform, wheel hub mounting angle plate, long bolt, the first positioning pin and the second positioning pin, wheel hub mounting angle plate is fixed on platen
On, the table top of wheel hub mounting angle plate bottom and platen is located by connecting by two positioning keys, and wheel hub mounting angle plate
Positioning surface forms an angle with cutter horizontal feed direction；Long bolt connects with the internal thread hole cooperation in the middle part of wheel hub mounting angle plate
It connects, and long bolt is perpendicular to the positioning surface of wheel hub mounting angle plate；First positioning pin and the second positioning pin are consolidated by nut and gasket
It is scheduled on wheel hub mounting angle plate, and the first positioning pin and the second positioning pin spacing distance and two 22 holes of φ on wheel hub to be processed
Position consistency, the first positioning pin and the second positioning pin are located by connecting respectively with two 22 holes of φ of wheel hub to be processed；Wheel to be processed
Hub is located in through long bolt end face on the positioning surface of wheel hub mounting angle plate, and pressing plate is crimped on through long bolt on wheel hub to be processed
It is fixed with nut.
Further, one division disk is further included, which is rotatably mounted on the positioning surface of wheel hub mounting angle plate.
Further, the both ends of wheel hub mounting angle plate offer semicircular opening.
Further, wheel hub mounting angle plate is a L-square shape structure, including a joint face and a positioning surface, joint face with
Platen connects, and positioning surface positions pin connection with the long bolt of wheel hub to be processed, the first positioning pin and second respectively.
Its advantage is the utility model compared with prior art：The frock of the utility model in hub drill, attack NPT1/
2 " during threaded hole, can rapid-mounted, be accurately positioned, and NPT1/2 " screw threads hole site stablize, size qualification, due to the use of special
Machine moves back and forth cutter without operative employee, so the labor intensity of operative employee substantially reduces, production efficiency also greatly improves, raw
Production beat was also foreshortened to 7 minutes by original 20 minutes, in addition, one is bored on Z3050 radial drilling machines, attacks NPT1/2 " screw threads
Hole tool outsourcing needs 1.2 ten thousand yuan, and this self-control bores, attacks just 3600 yuan of NPT1/2 " screw thread frocks total cost, and a self-control is special
Machine differs nearly 80,000 yuan with a Z3050 radial drilling machine, greatly reduces production cost.
Description of the drawings
Fig. 1 is the structure diagram of the utility model；
Fig. 2 is the top view of the utility model.
Specific embodiment
As depicted in figs. 1 and 2, a kind of hub drill, attack NPT1/2 " screw thread hole tools, it include platen 1, wheel hub
Mounting angle plate 2, long bolt 3, index dial, the first positioning pin 5 and the second positioning pin 6, wheel hub mounting angle plate 2 are fixed on lathe work
On platform 1, the bottom of wheel hub mounting angle plate 2 is located by connecting with the table top of platen 1 by two positioning keys 7, and wheel hub is consolidated
The positioning surface 8 and cutter horizontal feed direction for determining bent plate 2 form an angle；Long bolt 3 and the interior spiral shell at 2 middle part of wheel hub mounting angle plate
Pit is connected, and long bolt 3 is perpendicular to the positioning surface 8 of wheel hub mounting angle plate 2；First positioning pin 5 and the second positioning pin 6 are logical
Cross nut and gasket be fixed on wheel hub mounting angle plate 2, and the first positioning pin 5 and 6 spacing distance of the second positioning pin with it is to be processed
Two 22 hole sites of φ on wheel hub are consistent, the first positioning pin 5 and the second positioning pin 6 two φ 22 with wheel hub to be processed respectively
Hole is located by connecting；Wheel hub to be processed is located in through 3 end face of long bolt on the positioning surface 8 of wheel hub mounting angle plate 2, and pressing plate 9 passes through
Long bolt 3 is crimped on wheel hub to be processed and is fixed with nut.
Wherein, index dial is rotatably mounted on the positioning surface 8 of wheel hub mounting angle plate 2.The both ends of wheel hub mounting angle plate 2
