Problems solved by technology

The above-mentioned bushes need to be chamfered by the instrument lathe at least first, and then reamed with a reaming device (that is, the through hole of the machining center). In order to process the bushes of the commutator, more equipment needs to be used, which takes up a lot of space in the workshop. Large use area, more processing procedures for the overall product, which reduces production efficiency and prolongs the production cycle

Embodiment Construction

[0022] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0023] The invention protects a reaming device, which is not only suitable for processing the central through hole 11 of the commutator bushing 10, but also suitable for reaming and processing similar workpieces.

[0024] The existing reaming device uses more equipment, which occupies a larger usable area of ​​the workshop, and requires more processing procedures for the overall product, which reduces production efficiency and prolongs the production cycle. Therefore, it is necessary to design a reasonable reaming device.

[0025] Such as Figure 1 to Figure 7 As shown, this reaming device comprises frame 20, is installed on the frame 20 and is used for the incoming material channel of conveying liner 10, the fixed head 4...

Abstract

The invention provides a reaming device, which belongs to the technical field of machining. The reaming device comprises a rack, an incoming channel arranged on the rack and used for conveying a bush, and a fixing head movably arranged above the incoming channel, wherein a reamer arranged corresponding to the bush is fixedly arranged on the fixing head; the fixing head can drive the reamer to translate up and down along the vertical direction; the head end of the reamer is fixedly connected with the fixing head; a plurality of cutter teeth are arranged on the tail end of the reamer; a tooth slot is arranged between each two adjacent cutter teeth; the tail ends of the cutter teeth respectively extend outwards to form bulges; the outer side face of each bulge is transited to the adjacent bulge through an arc-shaped curved surface. The reaming device has the advantages of small occupied space and high production efficiency.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and relates to a reaming device, in particular to a reaming device suitable for processing commutator bushings. Background technique [0002] The commutator, commonly known as the commutator, is a part of the DC permanent magnet series motor in order to allow the motor to continue to rotate. The commutator generally includes a commutator piece, an insulating piece, and a bush used as a mounting base for the commutator piece and the insulating piece. There is a central through hole in the middle of the bush. Set the center through hole. [0003] In the prior art, when the reaming device is used to process the bushing of the commutator, since the end of the reamer of the reaming device is set on a plane, it is necessary to chamfer the middle of the bushing with an instrument lathe to facilitate reaming. The reamer of the hole device can smoothly extend into the middle of the bush an...
