Abstract
The utility model discloses a processing countersink for circular arc or inclined plane of a hole, which comprises a cutter bar, a blade and a guide nut, wherein the lower end of the cutter bar is provided with a threaded rod which is connected with the cutter bar into a whole, a through mounting groove is arranged on the threaded rod and the cutter bar, the blade is arranged in the mounting groove, and the threaded rod is connected with the guide nut by screw thread; the blade is of a square structure, and arc-shaped knife edges or inclined knife edges are arranged at four corners of the blade. The utility model discloses can be fast with drill way circular arc or inclined plane machine-shaping, machining efficiency is high, can use on drilling machine, milling machine, machining center moreover, and ordinary practicality is stronger.
Description
Technical Field
The utility model relates to a countersink specifically is a mouth circular arc or inclined plane processing countersink.
Background
When the orifice circular arc or the inclined plane is machined, the machining center adopts a universal cutter, the two sides of the hole need to be inverted circular arcs, and the machining center needs to turn over parts after one side is finished to finish machining of the other side, so that the operation machining efficiency is greatly reduced, and time is wasted.
SUMMERY OF THE UTILITY MODEL
The utility model provides a simple structure, convenient to use, the high drill way circular arc of machining efficiency or inclined plane processing countersink to overcome not enough among the prior art.
In order to solve the technical problem, the utility model provides a following technical scheme: the utility model provides an orifice circular arc or inclined plane processing countersink, includes cutter arbor, blade and guide nut, is provided with at the lower extreme of cutter arbor and links threaded rod as an organic whole with the cutter arbor, sets up the mounting groove that runs through on threaded rod and cutter arbor, installs the blade in the mounting groove, and threaded connection has guide nut on the threaded rod.
Furthermore, the blade is of a square structure, and arc-shaped knife edges or inclined knife edges are arranged at four corners of the blade.
Further, the outer diameter of the guide nut is smaller than the diameter of the machined hole.
Compared with the prior art, the utility model discloses the beneficial effect who reaches is: the utility model discloses can be fast with drill way circular arc or inclined plane machine-shaping, machining efficiency is high, can use on drilling machine, milling machine, machining center moreover, and ordinary practicality is stronger.

Description of reference numerals: 1-a guide nut; 2-a blade; 3, cutting a cutter bar; 4-mounting grooves; 5-threaded rod.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1 to 3, the present invention provides a technical solution: a countersink for processing an arc or an inclined plane of a hole comprises a cutter bar 3, a blade 2 and a guide nut 1, wherein a threaded rod 5 connected with the cutter bar 1 into a whole is arranged at the lower end of the cutter bar 3, a through mounting groove 4 is formed in the threaded rod 5 and the cutter bar 3, the blade 2 is mounted in the mounting groove 4, and the guide nut 1 is connected to the threaded rod 5 in a threaded manner; the blade 2 is of a square structure, and arc-shaped knife edges or inclined knife edges are arranged at four corners of the blade 2. The outer diameter of the guide nut 1 is smaller than the diameter of a processed hole, and the guide nut 1 plays a role in guiding a cutter to enter the hole so as to ensure the processing requirement of an arc or an inclined plane; and secondly, the blade 2 is locked to prevent the blade 2 from moving or shifting.
During the use, according to being processed the hole opening shape, select four corners to be blade 2 on circular arc or inclined plane to install blade 2 in the mounting groove 4 on cutter arbor 3, then screw up at cutter arbor 3 with guide nut 1, thereby can use with blade 2 is fixed. The utility model discloses can be fast with drill way circular arc or inclined plane machine-shaping, machining efficiency is high, can use on drilling machine, milling machine, machining center moreover, and ordinary practicality is stronger.
