Section and the diameter of spiro rod section is sequentially reduced, the positioning section of mandrel is fixedly connected by screw with pedestal；The pressing ring is sleeved on core
On the cylindrical section of axis, a circle circular conical surface, the circular conical surface and tooth hole to be drilled are provided between the lower end side and lower end surface of pressing ring
The fillet surface in the central shaft hole aperture of wheel is adapted；Nut is screwed on the spiro rod section of mandrel.
It further, further include limited block and spacer pin, the limited block is fixed on the pedestal of mandrel side, in limited block
On offer internal thread hole；The outer surface of the spacer pin is provided with external screw thread, and spacer pin level is screwed in interior on limited block
In threaded hole, where spacer pin is located at the cylindrical section of mandrel in altitude range, and the cylindrical section of mandrel is directed toward at the tip of spacer pin
Central axis.
When using the fixture clamping gear, nut and pressing ring are first removed, by geared sleeve to be processed on the cylindrical section of mandrel,
The positioning section of mandrel and the step of cylindrical section junction carry out axially position to gear, then pressing ring is successively sleeved on to the circle of mandrel
On shell of column, nut is screwed on the spiro rod section of mandrel, tightens nut, makes the circular cone between pressing ring lower end side and lower end surface
The cooperation of the fillet surface in face and the central shaft hole aperture of gear, the limit carried out vertically and horizontally to gear are fixed, most
After rotate spacer pin, by the tooth socket between two gear teeth adjacent on the tip of spacer pin insertion gear, is carried out to gear week
To limit, can drill on the end face of gear.
The beneficial effects of the utility model：
The chamfering in the central shaft hole aperture of gear is utilized in the fixture to drill on gear face described in the utility model
Face cooperates the fillet surface in the central shaft hole aperture of the circular conical surface and gear between pressing ring lower end side and lower end surface, to tooth
The limit that wheel carries out vertically and horizontally is fixed, and clamping process is simple, and is bored to each position on the end face of gear
Kong Shi can be completed the process disposably without adjusting fixture, improve processing efficiency.In addition gear is inserted at the tip of spacer pin
In tooth socket between upper two adjacent gear teeth, circumferential limit is carried out to gear, prevents gear from rotating in a circumferential direction along it, fills gear
It presss from both sides stronger reliable, it is therefore prevented that bore position offset.
