The utility model aims at prior art not enough, provide a positioner of band pulley axle, this positioner can follow the axial and radially advance line location, improve the machining precision.
The technical scheme of the utility model is that:
the utility model provides a positioner of band pulley axle, includes the multi-jaw chuck, the multi-jaw chuck passes through the connecting plate to be installed on the lathe, be equipped with a plurality of locating pieces that are used for pressing from both sides tight band pulley axle of waiting to process on the multi-jaw chuck, all be equipped with the stopper between each locating piece of multi-jaw chuck, each stopper passes through the second bolt fastening on the chuck body of multi-jaw chuck, all be equipped with at least one spacing boss on each stopper, spacing boss is used for cooperateing with the adjacent flank of tooth of waiting to process the band pulley axle.
Furthermore, each limiting block is provided with two limiting bosses.
Furthermore, the limiting block is of a circular arc structure.
Furthermore, each clamping jaw of the multi-jaw chuck is provided with a positioning block, each positioning block is fixed on the clamping jaw of the multi-jaw chuck through a first bolt, and the positioning blocks are used for radially positioning the belt wheel shaft to be processed.
Further, the multi-jaw chuck adopts a three-jaw chuck.
Furthermore, the positioning block is provided with an arc-shaped positioning surface matched with the belt wheel shaft to be processed.
Adopt above-mentioned technical scheme to have following beneficial effect:
the utility model has simple structure, is used for clamping the multi-jaw chuck of the belt pulley shaft and radially limiting the belt pulley shaft to be processed; the limiting blocks are additionally arranged on the multi-jaw chuck, each limiting block is provided with at least one limiting boss, and each limiting boss is matched with the tooth plane of the pulley shaft to be processed and used for axially limiting the pulley shaft to be processed. The utility model discloses a treat the shaft and carry out radially and axially spacing, the location is more accurate, has improved the machining precision of treating processing band pulley axle to band pulley axle after effectively having avoided processing takes place to interfere or abnormal sound with the parking pawl at the parking in-process.
All be equipped with two spacing bosss on each stopper, spacing through two spacing bosss, the location effect is better.
The following description is further described in conjunction with the accompanying drawings and the detailed description.

In the attached drawing, 1 is a multi-jaw chuck, 1-1 is a clamping jaw, 2 is a positioning block, 3 is a first bolt, 4 is a second bolt, 5 is a limiting block, 5-1 is a limiting boss, 5-2 is a countersunk bolt hole, 6 is a pulley shaft to be processed, and 7 is a connecting plate.
Detailed Description
Specific example 1:
referring to fig. 1 to 6, the positioning device for the belt pulley shaft comprises a multi-jaw chuck 1, wherein the multi-jaw chuck 1 is mounted on a lathe spindle through a connecting plate 7, a plurality of positioning blocks 2 used for clamping the belt pulley shaft 6 to be machined are arranged on the multi-jaw chuck 1, each clamping jaw 1-1 of the multi-jaw chuck 1 is provided with a positioning block 2, each positioning block 2 is fixed on the clamping jaw 1-1 of the multi-jaw chuck 1 through a first bolt 3, the positioning block 2 is provided with an arc-shaped positioning surface matched with the belt pulley shaft 6 to be machined, and the positioning block 2 is used for radially positioning the belt pulley shaft 6 to be machined. The multi-jaw chuck 1 may be a hydraulic chuck or a pneumatic chuck. In this embodiment, the multi-jaw chuck 1 is a three-jaw chuck, and three positioning blocks are disposed on the three-jaw chuck, which is the best embodiment. The multi-jaw chuck may also be a four-jaw chuck.
And a limiting block 5 is arranged between each two adjacent positioning blocks 2 of the multi-jaw chuck 1, and the limiting block 5 is of a circular arc structure. Each limiting block 5 is provided with a countersunk bolt hole 5-2, each limiting block 5 is matched and fixed on the chuck body of the multi-jaw chuck 1 through a second bolt 4 and the countersunk bolt hole 5-2, each limiting block 5 is provided with at least one limiting boss 5-1, and each limiting boss 5-1 is used for being matched with the adjacent tooth surface of the belt wheel shaft 6 to be processed, in the embodiment: three limiting blocks 5 are arranged between two adjacent positioning blocks 2 of the multi-jaw chuck 1, two limiting bosses 5-1 are arranged on each limiting block 5, and each limiting boss 5-1 is used for limiting a belt wheel shaft 6 to be processed.
The utility model discloses a theory of operation is: the belt pulley shaft is taken as an automobile engine belt pulley shaft for example, the multi-jaw chuck 1 drives the positioning block 2 to clamp the shaft end face of the belt pulley shaft 6 to be processed, and the belt pulley shaft is radially positioned. The axial positioning is carried out by matching the limiting boss 5-1 of the limiting block 5 with the tooth plane of the pulley shaft 6 to be processed, so that the pulley shaft is clamped and positioned in the radial direction and the axial direction. The axial size of the surface of the blank forged at the bottom of the belt wheel shaft tooth is guaranteed, and meanwhile, the belt wheel shaft and a parking pawl are prevented from interfering or causing abnormal sound in the parking process of the CVT.
