CN104107954A - Deburring device for part inner hole opening - Google Patents

Abstract

The invention discloses a deburring device for a part inner hole opening. The deburring device comprises a power device, a support and a rotary cutter and is characterized in that the rotary cutter is located in the middle of the deburring device, the rotary cutter is exactly located in the part inner hole opening when the deburring device extends into a part, a pull wire is pulled to drive the rotary cutter to rotate, the rotary cutter rotates repeatedly under spring force, and burrs of the part inner hole opening can be well removed. The deburring device is simple and compact in structure, high in efficiency, convenient to operate, especially suitable for machining occasions of precision parts such as aerospace parts, and the like.

Description

Inner bore of part aperture deburring device

Technical field

Patent of the present invention relates to a kind of instrument, particularly a kind of for removing the instrument of inner bore of part aperture burr.

Background technology

In Precision Machining, the burr of removing inside parts aperture aperture is a very difficult thing, main cause be these holes all at inside parts, the instrument of deburring has no idea to be deep into inside, but if the burr in aperture does not remove, will affect the quality that hole and other parts cooperatively interact.

Summary of the invention

In order to overcome above-mentioned the deficiencies in the prior art, this patent provides a kind of instrument of removing inside parts aperture aperture burr that is specifically designed to, and this instrument can be deep into inside parts, and inside parts aperture aperture burr is cleared up.

The technical solution adopted for the present invention to solve the technical problems is: deburring device mainly comprises power section, and holder part and rotary cutter partly form, and wherein power section is mainly comprised of spring and bracing wire.First burr remover is deep into inside parts, make rotary cutter just in time be arranged in inside parts aperture, by straining or loosening bracing wire, driven rotary cutter is realized positive and negative rotation, three blades above cutter can be realized removing repeatedly to the burr in aperture aperture, thereby reach the object of removing aperture burr.

Patent of the present invention is passed through technique scheme, there is following effect: can be deep into inside parts, burr for inside parts aperture aperture is cleared up, simple in structure, compact, efficiency is high and the feature such as easy to operate, is specially adapted to the occasion of the precision component processing such as aerospace.

Accompanying drawing explanation

Fig. 2 burring mechanism upward view;

1. supports in figure, 2. bracing wire, 3. screw 4. rotary cutters, 5. bearing, 6. spring, 7. rotating shaft.

The specific embodiment

As Fig. 1, shown in 2, inner bore of part aperture burr remover mainly comprises support 1, bracing wire 2, and rotary cutter 4, bearing 5, spring 6 and rotating shaft 7 form.Its medi-spring 6 one end are fixed on support 1, one end is connected with bracing wire 2, and rotating shaft 7 is walked around in bracing wire 2, and rotating shaft 7 interconnects by bearing 5 and support 1, reduced rotating shaft 7 suffered frictional force in rotary course, other one end and the rotary cutter 4 of rotating shaft 7 interconnect.In order to remove the burr of the little bore edges of inside parts, one end of inner-hole burr remover is reached to inside parts, make rotary cutter 4 just in time in endoporus, pull bracing wire 2, walk around cutter 4 of drive is rotated in bracing wire 2, spring 5 is extended simultaneously, loosen bracing wire 2, under the effect of spring 5 power, bracing wire 2 realizes driven rotary cutter 4 to rotate backward, when straining and loosening bracing wire 2, three blades that are distributed with interval 120 degree on rotary cutter 4 will be removed repeatedly to the burr at the little edge of inside parts, thereby can realize the removing to the little hole bur of inside parts.

Claims (3)

1. remove a special equipment for inside parts aperture burr, comprise cutter, power section and support, it is characterized in that: described cutter is the rotary cutter that three faces have sword, it interconnects by bearing and screw and support; Power section mainly comprises spring, stay cord and rotating shaft, and spring one end and frame interconnect, and one section is connected with stay cord, and rotating shaft is walked around in other one end of stay cord, by pulling stay cord, realizes the rotation of rotating shaft.

2. the special equipment of the aperture deburring of inside parts aperture according to claim 1, is characterized in that: cutter three is worn sword, can realize the burr in inside parts aperture aperture is back and forth removed under the effect of spring.

3. the special equipment of the aperture deburring of inside parts aperture according to claim 1, is characterized in that: the structure that in the middle of support adopts, stick up at protruding two, cutter can be deep into inside parts aperture aperture like this.
