Description

Jump ring groove processing cutter

Technical Field

The utility model relates to a cutter field mainly is a jump ring groove machining cutter.

Background

In the prior art, as shown in fig. 1-3, an ear part of a fork part is provided with a clamp spring groove 2, and to process the clamp spring groove 2, firstly, an ear hole is processed on the ear part 3 of the fork, then the part is clamped on a rotating main shaft, the part is driven to rotate by the rotating main shaft, an existing cutter is fed step by step, and chips form a clamp spring groove. The processing method has the defects that the lug hole is firstly processed and then the clamp spring groove is processed, so that after the clamp spring groove is processed, extrusion burrs are easily generated at the sharp corners at two sides of the clamp spring groove. When the fork earhole is assembled, the pressing-in of the universal joint shaft sleeve can be influenced due to the existence of burrs at the sharp corners, and poor assembly is generated, so that parts are scrapped or reworked and repaired.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome the not enough of prior art existence, and provide a jump ring groove processing cutter.

The purpose of the utility model is accomplished through following technical scheme. The utility model provides a jump ring groove processing cutter, includes the cutter main part, is equipped with main smear metal sword in the cutter main part, and the width of main smear metal sword and the groove width phase-match in jump ring groove still are provided with chamfer smear metal sword in the cutter main part.

Furthermore, the main cutting edge is provided with chamfering cutting edges for chamfering the cutting edges on both sides.

Furthermore, the cutter body comprises a cutter bar which is formed by extending in the radial direction, a connecting hole which is used for connecting a driving shaft is formed in the middle of the cutter bar, a main cutting edge which is a straight line is arranged at the tail end of the cutter bar, chamfering cutting edges are arranged on two sides of the main cutting edge in an oblique line mode, and the distance between the chamfering cutting edge and the main cutting edge is matched with the groove depth of the clamp spring groove.

Further, a plurality of main cutting edges and chamfer cutting edges are circumferentially and evenly distributed.

Further, the width of each main cutting edge is the same or different, and the inclination of the chamfer cutting edge is the same or different.

The beneficial effects of the utility model are that: adopt the utility model discloses a jump ring groove processing cutter for add man-hour in the jump ring groove, get rid of the burr of jump ring groove both sides closed angle department simultaneously, avoid scrapping and the phenomenon of doing over again because of the burr produces the assembly, improve production efficiency, reduce the quality loss.

Description of the reference numerals: the cutting tool comprises a tool body 1, a connecting hole 1-1, a main cutting edge 1-2, a chamfer cutting edge 1-3, a tool bar 1-4, a clamp spring groove 2 and a fork ear 3.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and embodiments:

as shown in FIG. 4, the clamp spring groove machining tool comprises a tool body 1, three main cutting edges 1-2 are arranged on the tool body 1, the width of each main cutting edge 1-2 is matched with the groove width of the clamp spring groove 2, and three chamfering cutting edges 1-3 are further arranged on the tool body 1. Three main cutting edges 1-2 and three chamfer cutting edges 1-3 are evenly distributed along the circumference. The width of each main cutting edge 1-2 can be the same or different according to requirements, if the width is the same, the other two main cutting edges 1-2 are used as spare parts, and if the width is different, the circlip groove 2 with different groove widths can be machined under the condition that a tool is not changed. At the same time, the inclination of the chamfer cutting edges 1-3 can also be the same or different, so that chamfers of different angles can be machined.

Specifically, chamfering cutting edges 1-3 for chip chamfering are arranged on two sides of a main cutting edge 1-2, the tool body 1 comprises three tool bars 1-4 formed in a radially extending manner, a connecting hole 1-1 for connecting a driving shaft is arranged in the middle of the tool body, the main cutting edge 1-2 in a straight line is arranged at the tail end of each tool bar 1-4, the chamfering cutting edges 1-3 are arranged on two sides of the main cutting edge 1-2 in oblique lines, the angle of the oblique lines is matched with the required chamfering angle, and the distance between the chamfering cutting edges 1-3 and the main cutting edge 1-2 is matched with the groove depth of a clamp spring groove 2.

The processing process is as shown in fig. 6-7, a fork ear part 3 (part) is clamped on a rotating main shaft, the rotating main shaft drives the part to rotate, a main cutting edge 1-2 of the new-structure cutter starts to feed a cutting clamp spring groove 2 step by step, the groove width of the clamp spring groove 2 is processed, when the cutter further feeds cuttings, the cutting edges 1-3 of the chamfers on the two sides of the new-structure cutter start to process small chamfers, sharp-corner burrs are removed, and the adverse effect of the burrs on assembly is eliminated.

The structure of the processed clamp spring groove 2 is shown in fig. 5, and as the clamp spring groove is cut, the function of simultaneously processing small chamfers at two sides of the clamp spring groove to remove burrs is added, the adverse effect of the burrs on assembly is eliminated, and other processes are not additionally added.

It should be understood that equivalent substitutions or changes to the technical solution and the inventive concept of the present invention should be considered to fall within the scope of the appended claims for the skilled person.
