A kind of fixture of the grinding for bearing outer ring
The present invention relates to the fixture of a kind of grinding for bearing outer ring.
During the outer circumference surface of lathe grinding bearing top circle, it is mostly to be fixed on the scroll chuck of lathe by this bearing outer ring by a chuck. The existing chuck for fixing bearing outer ring is easily deformed after multiple clamping, after repeatedly using, and clamping deleterious.
Therefore, necessary prior art improves to solve the deficiency of prior art.
Summary of the invention:
The present invention provides the fixture of a kind of grinding for bearing outer ring to solve above-mentioned prior art Problems existing.
The technical solution adopted in the present invention has: the fixture of a kind of grinding for bearing outer ring, including chuck, cylinder, diminished shaft and the latch segment being provided with locking through hole, described chuck is movably arranged in the locking through hole of latch segment, and one end stretches in outside locking through hole and fixes with the output shaft of cylinder and is connected, diminished shaft is plugged in chuck;
Described chuck includes clamping part, connecting portion and has the round platform portion of roundlet end face and large round end surface, and the large round end surface in described round platform portion is fixing with clamping part to be connected, and the roundlet end face in round platform portion is fixing with connecting portion to be connected; On described clamping part and round platform portion is equipped with breach, and the breach on clamping part connects with the breach in round platform portion; Described clamping part is provided with stage portion.
Further, described connecting portion be provided with female thread.
Further, the locking through hole on described latch segment includes the through-hole section and the cone locking portion that are interconnected.
There is advantages that
Present configuration is simple, and easy to use, clamping is effective, long service life.
Accompanying drawing illustrates:
Fig. 1 is the structure chart of present clip.
Fig. 2 is the tomograph of chuck in present clip.
Fig. 3 is the right view of Fig. 2 chuck.
Fig. 4 is the structure chart of latch segment in present clip.
Detailed description of the invention:
Below in conjunction with accompanying drawing, the present invention is further illustrated.
As shown in Figure 1 to Figure 4, the fixture of a kind of grinding for bearing outer ring of the present invention, including chuck 21, cylinder 23, diminished shaft 24 and the latch segment 22 being provided with locking through hole 220, chuck 21 is movably arranged in the locking through hole 220 of latch segment 22, and one end of chuck 21 stretches in, and outer and with cylinder 23 the output shaft of locking through hole 220 is fixing to be connected.Diminished shaft 24 is plugged in chuck 21.
Chuck 21 includes clamping part 210, connecting portion 211 and has the round platform portion 213 of roundlet end face and large round end surface, and the large round end surface in round platform portion 213 is fixing with clamping part 210 to be connected, and the roundlet end face in round platform portion 213 is fixing with connecting portion 211 to be connected. On clamping part 210 and in round platform portion 213, it is equipped with some breach 214, and the breach 214 on clamping part 210 connects with the breach 214 in round platform portion 213. Clamping part 210 is provided with the stage portion 215 for fixing bearing outer ring.
The present invention is connected with cylinder 23 for ease of chuck 21, is provided with female thread on chuck 21 connecting portion 211, corresponds ground, is provided with external screw thread (not shown in FIG.) on the output shaft of cylinder 23.
Locking through hole 220 on latch segment 22 includes the through-hole section 221 and the cone locking portion 222 that are interconnected, locks chuck 21 by the cone locking portion 222 on latch segment 22.
When grinding bearing outer ring, latch segment 22 in present clip is fixed on the three of lathe and grabs on chuck, the output shaft of cylinder 23 shrinks, chuck 21 is driven to move right in the locking through hole 220 of latch segment 22, cone locking portion 222 on latch segment 22 extrudes clamping part 210 and the round platform portion 213 of chuck 21, make clamping part 210 and round platform portion 213 that elastic deformation all occur, now the diameter of the stage portion 215 on chuck 21 diminishes, bearing outer ring to be ground is placed in the stage portion 215 of chuck 21, cylinder axis stretches out, bearing outer ring to be ground is stuck in the stage portion 215 of chuck 21, it is inserted into diminished shaft 24 to chuck 21, above-mentioned bearing outer ring is anchored on chuck 21.
The above is only the preferred embodiment of the present invention, it is noted that for those skilled in the art, can also make some improvement under the premise without departing from the principles of the invention, and these improvement also should be regarded as protection scope of the present invention.
