For the purpose of illustrating the objects, technical solutions and advantages of the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention.

The utility model provides a chuck positioner, including chuck locator 1, it is connected with the lathe three-jaw chuck, and basic shape is discoid, and three draw-in groove is seted up to the equipartition on the chuck locator 1, width, position and the three-jaw matches, be used for the three-jaw passes, central quotation diameter with hole matching between the three-jaw is used for sheltering from the piece that the work piece adds man-hour. The chuck positioner 1 is shaped as shown in fig. 1 and 2.

This chuck positioner maintenance is connected in the three-jaw chuck of lathe, steps down through 3 sizes and three-jaw assorted draw-in grooves, does not influence three-jaw clamping work piece, simultaneously, shelters from the hole between the three-jaw through central quotation, prevents that the metalworking piece of work piece from splashing to the headstock of lathe, feed case, carriage apron incasement through this hole, brings abluent extra work, or shortens center lathe's life.

Preferably, as shown in fig. 1, the disk surface of the chuck positioner 1 is provided with a threaded through hole matched with the three-jaw chuck, see the through holes on the three fan-shaped petals in the figure, and the threaded through hole is used for fixing the chuck positioner 1 to the three-jaw chuck through the connecting piece 2, as shown in fig. 5.

The chuck positioner 1 and the three-jaw chuck of the lathe can adopt a fixed connection mode and a movable connection mode, preferably adopts a movable connection mode, and the chuck positioner 1 is fixedly connected to the three-jaw chuck of the lathe through a connecting piece 2 (such as a self-tapping bolt). The chuck positioner 1 is convenient to replace according to the use scene.

Preferably, the chuck positioning device further comprises a positioning block 3 connected with the chuck positioner 1 and used for positioning a workpiece clamping position.

When the work piece adds man-hour, according to the difference of processing position, often need adjust the position that the work piece clamping was in three-jaw chuck, this application is through setting up the locating piece 3 with the relevant thickness in work piece clamping position, withstands the work piece tip through locating piece 3, can the diameter with three-jaw clamping work piece, avoids for the loaded down with trivial details measurement work of confirming work piece clamping position to and measure the error that the clamping introduced many times. The arrangement of the positioning block 3 is particularly effective when batch workpiece processing is carried out, and the processing efficiency of workpieces can be greatly improved.

Preferably, the positioning block 3 is arranged coaxially with the chuck positioner 1, and the positioning block 3 is disc-shaped, as shown in fig. 3 and 4.
