Description

Tool for removing burrs of circular truncated cone

Technical Field

The utility model relates to the machinery processing technology field, in particular to a frock for getting rid of round platform burr.

Background

In the field of machining, structural members such as box bodies, panels and the like are often designed with cylindrical bosses. Burrs can appear on the cylindrical boss milled by the numerical control machine tool. The traditional triangular scraper for removing burrs is easy to scratch and has low efficiency and poor consistency.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model provides a frock for getting rid of round platform burr. The tool can reduce deburring actions and improve the working efficiency.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a frock for getting rid of round platform burr, includes handle of a knife and tool bit, the end of tool bit 1 is equipped with a round platform form recess, and still is equipped with a plurality of incisions at the tool bit end, and the incision passes the tool bit outer wall and runs through to in the round platform recess.

Further, the tool shank is in threaded connection with the tool bit.

Furthermore, the number of the notches is three, the notches are arranged on the end head of the cutter head in a circumferential array mode, and the array center of the circumferential array is located on the central axis of the circular truncated cone-shaped groove.

Further, the tool handle comprises a fixed sleeve 3 and a rocker arm 2; the rocker arm comprises an upper part, a middle part and a lower part; the upper part and the lower part of the rocker arm are both positioned on the central axis of the circular truncated cone groove, and the upper part of the rocker arm is connected with the fixed sleeve through a bearing; the middle part of the rocker arm is positioned on one side of the central axis and is parallel to the central axis, and the middle part is connected with the upper part and the lower part through horizontal rods.

The utility model adopts the beneficial effect that above-mentioned technical scheme produced lies in:

1. the utility model discloses compare with the instrument that the cylinder boss burr was removed to the tradition, there is not the roll-off problem at burring in-process to avoided traditional triangle scraper because of the roll-off fish tail work piece.

2. The utility model discloses simple structure, cost of manufacture are low to have good economic benefits.

3. The utility model discloses a rocking arm, it is more laborsaving during the use.

In the figure: 1. tool bit, 2, rocking arm, 3, fixed cover.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific embodiments.

In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings of the embodiments will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and it is obvious for those skilled in the art that other drawings can be obtained according to these drawings without inventive labor.

Referring to fig. 1, according to the utility model discloses a frock for getting rid of cylinder boss burr, including rocking arm, fixed cover and tool bit. The tool rocker arm 2 is processed on a cylinder with the length of 150mm and the diameter of 13mm, is made of 45# steel, is subjected to thermal treatment quenching and tempering, bending and quenching, and is finally connected with the fixed sleeve 3 through a bearing. Wherein, the cylindrical screw thread boss that links to each other with the tool bit, diameter 5mm are processed to handle of a knife one end, and fixed cover and rocking arm bearing are connected. Referring to fig. 2, the cutter head is manufactured by using a cylindrical bar with the length of 30mm and the diameter of variable, the material is 45# steel, and the quenching and tempering and the quenching are needed to be carried out through heat treatment. The bottom is provided with a thread blind hole matched with the cylindrical thread boss, and the diameter of the inner hole is 5 mm. The cutter head is provided with an inner taper angle groove, and the end face of the groove is provided with three blades which are uniformly distributed along the radius direction of 120 degrees.

The above description is only an embodiment of the present invention, but the present invention is not limited to the embodiment. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit and principle of the invention, and the equivalents or substitutions are included in the scope defined by the claims of the present application.
