Abstract
The utility model discloses an abrasion-resistant positioning disk used for a machine tool. The positioning disk comprises a positioning disk body, multiple positioning holes are arranged on the positioning disk, ring grooves are arranged along inner walls at opening ends of the positioning holes, internal threads are arranged on ring walls of the ring grooves, abrasion-resistant rings are in threaded fit in the ring grooves, and the inner diameter of the abrasion-resistant rings is identical with that of the positioning holes. The abrasion-resistant positioning disk used for the machine tool is simple in structure and convenient to mount and use, the design that the ring grooves are arranged at the opening ends of the positioning holes and the abrasion-resistant rings are in threaded fit in the ring grooves is adopted, so that abrasion resistance of the positioning holes is effectively enhanced, and the service life is prolonged; and when the abrasion-resistant rings are worn and normal use is influenced after long-time use, new abrasion-resistant rings can be replaced for continuous use, the whole positioning disk does not need to be replaced, operations are convenient and quick, production cost is saved, and production efficiency is improved.
Description
Technical field
The utility model relates to a kind of positioning disk, is specially a kind of for lathe wear-resisting type positioning disk.
Background technology
At present, in the machining grinding machine of each lathe manufacturer production, use in a large number positioning disk, to make things convenient for the processing of workpiece.Positioning disk is provided with several in order to the locating hole of positioning workpieces, and after the long-time use of existing positioning disk, its locating hole is because repeatedly installing/dismounting workpiece and easily wearing and tearing, affect positioning accuracy and steadiness, and then impact also can cause the damage of workpiece to the process operation of workpiece when serious, therefore service life is shorter, need often to change, both affected operating efficiency, increased again production cost.
Description
The purpose of this utility model provides a kind of for lathe wear-resisting type positioning disk, after solving the long-time use of positioning disk traditional in the prior art, its locating hole easily weares and teares, affect positioning accuracy and steadiness, and then impact is to the process operation of workpiece, and service life is shorter, needs often to change, affect operating efficiency, increase the problem of production cost.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of for lathe wear-resisting type positioning disk, it is characterized in that: include the positioning disk body, described positioning disk is provided with several locating holes, the openend of described locating hole is provided with annular groove along inwall, the ring wall of described annular groove is provided with internal thread, be screwed with wear ring in the described annular groove, described wear ring internal diameter is identical with the locating hole internal diameter.
Described a kind of for lathe wear-resisting type positioning disk, it is characterized in that: the opening part of described wear ring is provided with chamfering.
The beneficial effects of the utility model are:
The utility model is simple in structure, easy to install, adopt the openend at locating hole that annular groove is set, and in annular groove, screw togather the design of wear ring, effectively strengthened the wearability of locating hole, prolonged service life, when impact was normally used if the rear wear ring of long-time use is frayed, replaceable new wear ring was with the continuation use, needn't change whole positioning disk, convenient to operation, and saved production cost, improved production efficiency.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of for lathe wear-resisting type positioning disk, include positioning disk 1 body, positioning disk 1 is provided with several locating holes 2, the openend of locating hole 2 is provided with annular groove 3 along inwall, the ring wall of annular groove 3 is provided with internal thread, is screwed with wear ring 4 in the annular groove 3, and wear ring 4 internal diameters are identical with locating hole 2 internal diameters.The opening part of wear ring 4 is provided with chamfering 5.
Claims (2)
1. one kind is used for lathe wear-resisting type positioning disk, it is characterized in that: include the positioning disk body, described positioning disk is provided with several locating holes, the openend of described locating hole is provided with annular groove along inwall, the ring wall of described annular groove is provided with internal thread, be screwed with wear ring in the described annular groove, described wear ring internal diameter is identical with the locating hole internal diameter.
