Abstract
The title of the invention is Undercutting Group Knife for Commutator of Traction Motor, belonging to the technical filed of an undercutting group knife used by an undercutter. The invention mainly solves the problems of reduced roughness which is caused by the facts that in the existing cutting knife, unsymmetrical and bias cutting easily occur to the cut slots and chamfers, chatter marks are generated on the surface of cut chamfers with 0.6* 45 degrees, and the surface of the chamfers is scratched by the side of the undercutting knife. The undercutting group knife is characterized by comprising a knife carrier, two chamfering blades with an 90-degree included angle and a slot cutting blade, wherein the chamfering blades are arranged on the end part of the knife carrier; two corresponding relief angles are arranged corresponding to the side of the two chamfering blades; and the slot cutting blade is positioned at the tip of the two chamfering blades and is symmetrical to the two chamfering blades. The invention has the characteristics that the undercutting knife has high rigidity and the surface quality of cut slots and chamfers meet design requirements, and the undercutting group knife is mainly applied to the undercutter to process the commutator of the traction motor.
Description
Technical field
The invention belongs to undercutter with carving group's cutter technical field down.Be specifically related to a kind of undercutting group knife for commutator of traction motor that is used on undercutter, traction motor commutator being carried out chamfering and cutting processing.
Background technology
At present, the following icking tool that is used for traction motor commutator processing has two kinds.
A kind ofly be made up of two cuttves, as shown in Figure 1 and Figure 2, they are made up of rose reamer 1 and 2 two cuttves of scoring blade.Wherein rose reamer 1 comprises that two chamfering blades 3 and 5, two chamfering blades 3 angles of two relief angles are 90 °, is used for carving 0.6 * 45 ° of chamfering of two close commutator segments on the commutator; Relief angle 5 is angles of rose reamer 1 side and the direction of motion, is used for protecting that 0.6 * 45 ° of chamfer surface is not scratched on the commutator commutator segment during following quarter.Scoring blade 2 comprises a rectangular channel sword 4, is used to carve mica between commutator two commutator segments, forms a rectangular channel.The course of work: the undercutter hold-down bolt is fixed on rose reamer 1, scoring blade 2 on the tool rest, rose reamer 1 dress front, and scoring blade 2 is contained in the back, and at this moment their blade is symmetrical; Under when carving, the undercutter tool rest drives down that icking tool moves forward, rose reamer 1 carves 2 0.6 * 45 ° of chamferings on commutator two close commutator segments, and then scoring blade 2 is inscribed mica between commutator two commutator segments, forms a rectangular channel.Guarantee that the chamfering and the rectangular channel that carve are symmetrical.
Because the undercutter hold-down bolt will descend the icking tool symmetry to be fixed on the tool rest, be subjected to factor affecting such as impact and installation accuracy during work, make the groove and the easy appearance of the chamfering phenomenon at asymmetric and inclined to one side quarter that carve; In addition, owing to be subjected to the influence of commutator escape width and tool rest installing hole size, every knife bar thickness is restricted, make their insufficient rigidity, occur easily vibration during work and make down the icking tool knife or carve 0.6 * 45 ° of chamfer surface generation line that quivers down, have a strong impact under the commutator quality at quarter.
Another kind is to be made of 1 cutter, and as shown in Figure 3, it is to be made of knife bar 6, chamfering blades 3 and cutting sword 4.Wherein chamfering blades 3 and cutting sword 4 are symmetrical, one, and two chamfering blades 3 angles are 90 °, but do not have relief angle.The course of work: the undercutter hold-down bolt is fixed on knife bar 6 on the tool rest; Under when carving, the undercutter tool rest drives down that icking tool moves forward, chamfering blades 3 carves 2 0.6 * 45 ° of chamferings on commutator two copper sheets, the sword 4 of cutting is simultaneously inscribed mica between commutator two copper sheets, forms a rectangular channel.Guarantee that the chamfering and the rectangular channel that carve are symmetrical.
Because icking tool is to be made of a cutter down, cutting sword 4 and chamfering blades 3 all are the symmetries of one, thereby guarantee that the chamfering and the rectangular channel that carve are symmetrical.Simultaneously owing to be hilted broadsword, its knife bar thickness is bigger than first kind of following icking tool, has overcome shortcomings such as first kind of following icking tool rigidity is low, easy vibration.But because icking tool does not have relief angle down, make icking tool side scuffing under 0.6 * 45 ° of chamfer surface quilt that processes, roughness is reduced.
Summary of the invention
Purpose of the present invention is exactly the undercutting group knife for commutator of traction motor that provides a kind of icking tool rigidity height, the groove that carves and chamfer surface quality down to adhere to specification at above-mentioned weak point.
Technical solution of the present invention is: a kind of undercutting group knife for commutator of traction motor, comprise 2 chamfering blades and 1 cutting swords that are 90 ° of angles that knife bar, knife bar end are provided with, it is characterized in that: the relief angle that is provided with 2 correspondences in the side of 2 chamfering blades correspondence; The cutting sword is positioned at the tip place of 2 chamfering blades, and with 2 chamfering blades be symmetrical.
The present invention is owing to adopt the undercutting group knife for commutator of traction motor that is made of knife bar, chamfering blades, cutting sword and relief angle, and group cutter only will be made of a cutter at following quarter, its cutting sword and chamfering blades are one, symmetry, article two, the chamfering blades angle is 90 °, knife bar thickness is moderate, good rigidly, the anti-vibration ability is strong, make down carve groove and 45 ° of chamferings be symmetrical, line does not quiver.Owing to be provided with the relief angle of 2 correspondences, thereby can protect that 0.6 * 45 ° of chamfer surface is not scratched on the commutator commutator segment when carving down in the side of 2 chamfering blades correspondence.The present invention has the advantages that following icking tool rigidity height, the groove that carves and chamfer surface quality adhere to specification.The present invention is mainly used in group cutter at following quarter of processing traction motor commutator on undercutter.

Embodiment
As Fig. 4, shown in Figure 5.Following icking tool mainly comprises 4,2 relief angles 5 of 3,1 cutting sword of 6,2 chamfering blades of knife bar.Wherein 2 chamfering blades 3 angles are 90 °, and 2 chamfering blades 3 and 1 cutting sword 4 are symmetrical.During work: the undercutter hold-down bolt is fixed on knife bar 6 on the tool rest, the undercutter tool rest drives down, and icking tool moves forward, chamfering blades 3 is poured out 2 0.6 * 45 ° of chamferings on two copper sheets, the sword 4 of cutting is simultaneously inscribed mica between commutator two copper sheets, forms a rectangular channel.Because 2 chamfering blades 3 and 1 cutting sword 4 are symmetrical one, make down to carve rectangular channel and 2 0.6 * 45 ° of chamferings are symmetrical.Secondly owing to be hilted broadsword, thickness is moderate, and good rigidly, antivibration ability force 0.6 * 45 ° of chamfer surface the line that quivers can not occur.Owing to increase relief angle 5, guarantee that 2 0.6 * 45 ° of fillet surfaces can not be scratched once more, roughness is effectively protected.
ZQDR-410, ZQDR-410C, Z109B, Z109C engine commutator are the motor vitals, and its performance directly influences motor properties, and its importance is self-evident.Because commutator importance, above-mentioned motor its is required is very high, if carving partially appears in commutator, chamfer surface has the line of quivering, roughness is excessive, chamfering is different, can cause the engine commutator blackout, ring fire, scrape carbon dust.Since adopting icking tool down of the present invention, commutator was carved quality down and was improved greatly because the cutter problem causes a lot of accidents past, thus the generation of reduction accident, for the economic benefit that improves company is made contributions.
