The embodiments of the present invention will be further explained with reference to the drawings.

Example 1

Referring to fig. 1-5, a emery stick grinding frock, includes frock body 1, frock body 1 is the cavity cylindricality, is equipped with emery stick slot 2 and extension spring groove 3 on the frock body 1, emery stick slot 2 just follows the axial extension of frock body 1 with the inside intercommunication of frock body 1, extension spring groove 3 is the annular and intersects with emery stick slot 2, is equipped with annular extension spring 4 in the extension spring groove 3, and the coaxial regulation core 5 that rises that is equipped with the round platform shape in the frock body 1, it is connected with set screw 6 to adjust the core 5 that rises, 6 threaded connection of set screw is in the frock body 1.

The sand strip slots 2 are four and are evenly arranged along the circumferential direction of the tool body 1.

The tension spring grooves 3 are provided with two ends which are respectively arranged at the sand bar inserting grooves 2.

One end part of the adjusting expansion core 5 is provided with an internal thread hole, and one end part of the fixing screw 6 is provided with a connecting part 7 in threaded connection with the internal thread hole.

Threaded connection has jackscrew 8 on the frock body 1, jackscrew 8 radially extends along frock body 1 and with fixed screw 6 butt.

The adjusting expansion core 5 and the fixing screw 6 are both provided with a center hole 9.

In the embodiment, the center hole 9 is arranged at the end parts of the adjusting expansion core 5 and the fixing screw 6, and the outer circular surface of the adjusting expansion core 5 is matched with the inner inclined surface of the sand strip to be ground; during the actual use, the number of sand strip slot 2 sets up according to the quantity of sand strip in every group sand strip.

The adjusting expansion core 5 and the fixing screw 6 are in threaded connection and are directly tightened, so that the adjusting expansion core 5 and the fixing screw 6 are ensured not to be loosened in the process of grinding, and the arrangement is convenient to replace the adjusting expansion core 5 with different outer circular surfaces on one hand so as to be suitable for sand bars with different inner side inclined surfaces; on the other hand, the adjusting expansion core 5 can be always connected with the fixing screw 6, and the adjusting expansion core 5 can move synchronously with the fixing screw 6 when the fixing screw 6 is screwed, so that the fixing screw 6 can effectively adjust the position of the adjusting expansion core 5.

The setting of jackscrew 8 can be spacing to set screw 6, prevents that set screw 6 from taking place rotation or axial float to guarantee to adjust the fixed of 5 positions of expanding the core, and then guarantee that the emery stick position is unchangeable, guarantee the precision of grinding.

The center hole 9 is arranged, so that the tool can be conveniently installed on the center of the grinding equipment, and the fixture is fixed.

When the tool is used, the position of the expansion core 5 is adjusted according to the grinding requirement of the sand bars to be ground (the height of the sand bars to be ground leaking out of the tool body 1), a group of sand bars are arranged in each sand bar slot 2 of the tool body 1, and the tension spring 4 is tensioned to fix the sand bars; and then, the tool body 1 is arranged on a cylindrical grinding machine for grinding, and the sand bars are taken out after the grinding is finished. The utility model discloses can once accomplish the grinding of a set of emery stick, labour saving and time saving not only, the arc surface that every emery stick ground out moreover is unanimous, and the matching degree is high, has guaranteed the precision of honing. In addition, because the adjusting expansion core 5 is fixed, the time for adjusting the position of the sand bar during grinding each time can be saved, the grinding time is further saved, and the grinding efficiency is improved.

The utility model discloses a fixed screw 6 changes the position of adjusting the core 5 that rises to the radial position of grinding emery stick is treated in the change, can be applicable to the different grinding requirements of emery stick.
