Description
Technical Field
The utility model relates to the technical field of machining tools, in particular to a precise diameter adjusting structure for a tool.
Background
At present, in the field of boring and reaming tools for precision machining, when facing holes with machining tolerance within 6-level tolerance level, in order to submit the service life of a tool, a diameter adjusting structure is designed generally, a screw with a conical surface is contacted with a tool body, the tool body is spread along the conical surface along with the screwing of the screw, so that the function of adjusting the diameter is achieved, but at present, the error precision of machining is not high due to the characteristics of a threaded hole, so that the screw is easy to deviate during screwing adjustment, the spread diameter is uneven, and the precision of the tool is affected.
Therefore, the utility model provides a new technical scheme.
Disclosure of utility model
The utility model provides a precise diameter adjusting structure for a cutter, which is characterized in that a cylindrical positioning section is added on an adjusting screw to compensate errors of a threaded hole and improve diameter expansion precision.
The utility model is realized by the following technical scheme:
The utility model provides a be used for cutter diameter precision adjustment structure, includes cutter body and conical surface adjusting screw, conical surface adjusting screw inserts in cutter body, taper hole, location cylinder hole and screw hole have been seted up in proper order to cutter body inner chamber, conical surface adjusting screw is equipped with tapering axle, location cylinder axle and screw thread axle, screw thread axle cooperatees with the screw hole in the cutter body, location cylinder axle and location cylinder hole clearance fit, tapering axle cooperatees with the taper hole.
Further, the taper shaft, the positioning cylinder shaft and the threaded shaft are of an integrated structure.
The beneficial effects of the utility model are as follows:
According to the utility model, a section of positioning cylinder shaft is added on the conical surface adjusting screw, the positioning cylinder shaft is used for guiding and supporting the screw, and meanwhile, a positioning cylinder hole matched with the positioning cylinder shaft is processed in the cutter body, so that when the conical surface adjusting screw is screwed, the error of a threaded hole and the diameter expansion precision are compensated.
Drawings
FIG. 1 is a schematic diagram of the structure of the present utility model;
FIG. 2 is a schematic view of the structure of the cutter body;
FIG. 3 is a schematic view of the structure of the conical surface adjusting screw.
Wherein: 100. the tool comprises a tool body 200, conical surface adjusting screws 101, conical holes 102, positioning cylindrical holes 103, threaded holes 201, conical shaft 202, positioning cylindrical shafts 203 and threaded shafts.
Description of the embodiments
The utility model is further described with reference to the following description of the drawings.
As shown in fig. 1-3, a precise cutter diameter adjusting structure comprises a cutter body 100 and a conical surface adjusting screw 200, wherein the conical surface adjusting screw 200 is inserted into the cutter body 100, a conical hole 101, a positioning cylindrical hole 102 and a threaded hole 103 are sequentially formed in an inner cavity of the cutter body 100, the conical surface adjusting screw 200 is provided with a conical shaft 201, a positioning cylindrical shaft 202 and a threaded shaft 203, the threaded shaft 203 is matched with the threaded hole 103 in the cutter body 100, the positioning cylindrical shaft 202 is in clearance fit with the positioning cylindrical hole 102, the conical shaft 201 is matched with the conical hole 101, and the conical shaft 201, the positioning cylindrical shaft 202 and the threaded shaft 203 are of an integral structure.
In the technical scheme, the conical surface adjusting screw 200 is installed in the threaded hole 103 through the threaded shaft 203, and the positioning cylinder shaft 202 and the positioning cylinder hole 102 are in clearance fit in the screwing process, so that the auxiliary guiding function is realized, and the phenomenon that the conical surface adjusting screw 200 and the cutter body 100 are not coaxial due to errors of the threaded hole 103 is prevented. Meanwhile, the taper shaft 201 contacts with the taper hole 101 during screwing, and the outer diameter of the cutter body 100 is gradually increased along with continuous screwing of the taper adjusting screw 200, so that the cutter size is adjusted.
The foregoing has shown and described the basic principles, principal features and advantages of the utility model. It will be understood by those skilled in the art that the present utility model is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present utility model, and various changes and modifications may be made without departing from the spirit and scope of the utility model, which is defined in the appended claims. The scope of the utility model is defined by the appended claims and equivalents thereof.
