Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a schematic structural diagram of the present invention;
fig. 2 is a right side view of fig. 1.
In the figure, 1, a tooth clamping part, 2, a first fixing plate, 3, a first positioning fixing column, 4, a threaded rod, 5, a second fixing plate, 6, a second positioning fixing column, 7, a fixing nut, 8, a rubber gasket and 9, a gear piece are arranged.
Detailed Description
Fig. 1 is the utility model discloses a schematic structure, a gear clamping positioner, including clamping part 1, 1 front end of clamping part is equipped with first fixed plate 2 and 2 terminal surfaces of first fixed plate are equipped with first location fixed column 3, 2 terminal surface center departments of first fixed plate are fixed with threaded rod 4, wear to be equipped with second fixed plate 5 on the threaded rod 4, 5 terminal surfaces of second fixed plate are equipped with second location fixed column 6, 5 one side of second fixed plate just are located the threaded rod 4 and are equipped with fixation nut 7.
Referring to fig. 1 and 2, the first fixing plate 2 is cylindrical, and at least four first positioning fixing posts 3 are circumferentially arrayed on the cylindrical surface at the center of the cylinder. The second fixing plate 5 is cylindrical, at least four second positioning fixing columns 6 are arranged on the cylindrical surface in a circular array around the center of the cylinder, and the number of the second positioning fixing columns 6 is consistent with that of the first positioning fixing columns 3. First fixed column 3 and 6 tops of second fixed column all are equipped with rubber gasket 8, when first fixed column 3 and 6 pairs of gear spare of second fixed column press from both sides the tooth, rubber gasket 8 has avoided leaving the clamp seal in the gear spare 9 side, also can increase first fixed column 3 and 6 pairs of gear spare longitudinal frictional force of second fixed column through rubber gasket 8 simultaneously, and then increases its double-layered tooth fastness, be equipped with between first fixed column 3 and the second fixed column 6 and take the place of processing gear spare 9 and first fixed column 3 and 6 terminal surfaces of second fixed column and gear spare 9 both sides side contact. The diameter of the threaded rod 4 is smaller than that of the central mounting hole of the gear piece 9, the center of the second fixing plate 5 is provided with a central hole for penetrating the threaded rod 4, and the diameter of the central hole is larger than that of the threaded rod 4. The fixed nut 7 is connected on the threaded rod 4 in a threaded fit manner and is positioned on the outer side surface of the second fixed plate 5. The outer ring diameter of the first fixing plate 2 and the second fixing plate 5 is smaller than the outer tooth diameter of the gear piece 9 to be processed.
When in use, the clamping part 1 is clamped at the machine tool clamping teeth, then the middle part of the gear piece 9 passes through the threaded rod 4 and one side surface of the gear piece is abutted against the first positioning fixed column 3, then the second fixed plate 5 passes through the threaded rod 4 and the second positioning fixed column 6 is abutted against the other side surface of the gear piece 9, then the second fixed plate 5 is screwed up through the rotation of the fixing nut 7, so that the clamping teeth of the gear piece 9 by the first positioning fixed column 3 and the second positioning fixed column 6 are realized, the rubber gaskets 8 are respectively arranged at the top ends of the first positioning fixed column 3 and the second positioning fixed column 6, when the gear piece 9 is clamped by the first positioning fixed column 3 and the second positioning fixed column 6, the rubber gaskets 8 avoid the clamping printing left on the side surface of the gear piece 9, meanwhile, the friction force of the first positioning fixed column 3 and the second positioning fixed column 6 to the longitudinal direction of the gear piece 9 can be increased through the rubber gaskets 8, so as to increase the clamping, according to the clamping and positioning device, the clamping teeth are arranged on the side wall of the gear piece, so that the precision of the gear tooth part and the mounting hole is ensured, and the gear tooth part and the mounting hole cannot be abraded in the machining process.
