Description

Small-size part drill way burring frock

Technical Field

The utility model relates to a small-size part drill way burring frock is applicable to and gets rid of the less part drill way burr overlap of each type volume.

Background

At present, the method for removing the orifice burrs is developed from the traditional manual deburring by a bench worker to the deburring of a special cutter of a numerical control machine tool, and the two methods for removing the burrs have the advantages respectively, but have the defects at the same time.

Firstly, the advantages of convenience and rapidness in removing the orifice burrs manually by a fitter, low processing cost and suitability for processing small-batch parts, but the processed parts are not attractive, poor in consistency and high in labor intensity when the batch is large; the special tool for the numerical control machine tool has the advantages that machined parts are attractive in appearance, good in consistency and high in efficiency when being large in batch, but the machining time and the tool loss of the machine tool need to be consumed, so that the machining cost is high, and the special tool for the numerical control machine tool is suitable for large parts.

Aiming at small-volume parts, a method for removing burrs of most of burrs of an orifice is adopted by a bench worker. However, no applicable tool exists at present, manual machining is performed by operators, and therefore efficiency is low and accuracy is poor.

Wherein: the tool comprises a base 1, a support 2, a rolling bearing 3, a rotary handle 4, a cutter bar 5, a locking nut 6, a chamfer cutter 7, a jacking type screw 8 and a part 9.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings.

Examples

As shown in the figure, the small part orifice deburring tool comprises a base 1, a support 2, a rolling bearing 3, a rotating handle 4, a cutter bar 5 and a chamfering cutter 7; the bottom end of the bracket 2 is fixed on the base, and the upper part of the bracket 2 is provided with a mounting through hole; the outer edge of the rolling bearing 3 is arranged in the through hole of the bracket, the cutter bar 5 penetrates through the inner hole of the rolling bearing 3, and the rolling bearing 3 drives the cutter bar 5 to do rotary motion; one end of the cutter bar 5 is connected with the rotating handle 4, and the other end of the cutter bar 5 is connected with the chamfering cutter 7.

Wherein, base 1 can make the cuboid, can cast the shaping in the actual production and processing, and finish machining reference surface makes, further practices thrift the processing cost.

The bracket 2 is designed into a hollow structure, so that the weight of the tool is reduced, and the tool is convenient to move; 10-20 counter bores are arranged on the bracket 2, and the base 1 and the bracket 2 are fixed by 10-20M 12 socket head cap screws.

The rolling bearing 3 adopts a common cylindrical roller bearing, so that the use requirement can be met, and the manufacturing cost can be reduced. An inner hole of the rolling bearing 3 is in interference fit with a base hole of the cutter bar 4; the outer edge of the rolling bearing 3 is in interference fit with the through hole of the bracket 2 by adopting a base shaft system.

The rotary handle 4 is formed by adopting a precision forging mode, and only a matching hole needs to be precisely bored according to the outer diameter of the cutter bar 5; the cutter bar 5 is in clearance fit with the rotary handle 4, and the cutter bar 5 and the rotary handle 4 are fixed through an M6 outer hexagonal jacking type screw 8.

The cutter bar 5 is in clearance fit with the chamfer cutter 7, and the cutter bar 5 locks the chamfer cutter 7 through a locking nut 6; the threaded part of the cutter bar 5 is designed into a shape with a notch, and when the nut is screwed down, the notch part deforms under stress to clamp the chamfer cutter.
