The bevel gear shaft dual-positioning grinding fixture comprises a front cover, a spring collet, a conical body and a tension sleeve, wherein an inner hole of the spring collet is a step hole matched with two journals of the bevel gear shaft; the conical body is a hollow shaft; the outer circle of a shaft at the left end is matched with the front cover; an inner conical hole at the left end is matched with an outer conical surface at the left end of the spring collet; an outer conical surface at the right end of the spring collet is matched with an inner conical hole of the tension sleeve; the outer circle of the tension sleeve is matched with an inner hole at the right end of the conical body; the right end of the conical body is provided with an outer conical surface connected with a machine tool; the right end of the tension sleeve extending out of the conical body is provided with a thread connected with the machine tool; in the direction of the outer conical surface at the left end of the spring collet, the left end is high, and the right end is low; and in the direction of the outer conical surface at the right end of the spring collet, the right end is high, and the left end is low.
Description
Technical field
Present technique relates to a kind of bevel gear shaft grinding clamp.
Background technology
Bevel gear shaft is the driving gear in the automobile axle, and its shank is established two bearing necks, and during grinding, axle journal is supporting before the prior art, and back axle journal clamps.But supporting causes bevel gear shaft and clamp body axle offset for matched in clearance before this mechanism, makes gear pair that the back meshing quality is installed and descends, and causes the transmission noise big.In addition owing to be grinding step, in the prior art wearing and tearing of protecgulum very serious, can not guarantee product quality.
Summary of the invention
The purpose of present technique provides a kind of accurate positioning, guarantees the bevel gear shaft machining accuracy and weares and teares the two location of little bevel gear shaft grinding clamp.
The two location of this bevel gear shaft grinding clamp comprises protecgulum 1, collet 2, tapering body 3, tension cover 4; Collet 2 endoporus are two stepped holes that axle journal matches with bevel gear shaft; Described tapering body 3 is hollow shaft, and the left end shaft cylindrical matches with protecgulum 1, and the internal taper hole of left end cooperates with collet 2 left end male cone (strobilus masculinus)s; The right-hand member male cone (strobilus masculinus) of collet 2 cooperates with tension cover 4 internal taper holes, and tension cover 4 cylindricals cooperate with tapering body 3 right-hand member endoporus, and tapering body 3 right-hand members have the male cone (strobilus masculinus) that links to each other with lathe, and the tension of extension taper body 3 is overlapped 4 right-hand members and had the screw thread that is connected with lathe; Collet 2 left end male cone (strobilus masculinus) directions are that left end height, right-hand member are low; Collet 2 right-hand member male cone (strobilus masculinus) directions are that right-hand member height, left end are low.
The two location of above-mentioned bevel gear shaft grinding clamp, tension cover 4 cylindricals and tapering body 3 right-hand member endoporus are matched in clearance.
The two location of above-mentioned bevel gear shaft grinding clamps, tapering body 3 are provided with the lock screw 5 in the gathering sill that extend into out on collet 2 outer walls; Described gathering sill is parallel to the axis of collet.
The two location of above-mentioned bevel gear shaft grinding clamp, tapering body 3 is provided with along the lock screw 6 that extend into out in straining the gathering sill that overlaps on 4 outer walls; Described gathering sill is parallel to the axis of tension cover.
The beneficial effect of present technique: the present invention compared with prior art has the following advantages:
1, in the swelling mode workpiece is located, eliminate matched in clearance, accurate positioning, machining accuracy height.
2, utilize the collet two ends to clamp, eliminate effect of attrition, increase anchor clamps service life.
Description of drawings
Fig. 1 is the schematic diagram of the two location of this bevel gear shaft grinding clamp.
The specific embodiment
By reference to the accompanying drawings present technique is further described below by embodiment.
The two location of bevel gear shaft grinding clamps as shown in Figure 1, it comprises protecgulum 1, collet 2, tapering body 3, tension cover 4, lock screw 5,6.Described tapering body 3 is hollow shaft, different taperings are set up at two ends separately, the left end shaft cylindrical matches with protecgulum 1, the left end internal taper hole cooperates with collet 2 left end external tapers, collet 2 right-hand member external tapers cooperate with tension cover 4 internal taper holes, tension cover 4 cylindricals and tapering body 3 right-hand member endoporus matched in clearance, tapering body 3 right-hand member taperings are connected with lathe, and tension cover 4 rib-loops are connected with lathe.So form drawing mechanism, so that the clamping of workpiece and loosening.
