Abstract
The utility model provides a lower groove carving knife for the reverser of a pulling motor and belongs to the technical field of the lower groove carving knife for a lower carver. The utility model mainly solves the problems that the prior carving knife has the phenomenon that the carved groove and chamfer are easily asymmetrical and deflected, the carved chamfered surface of 0.6*45 degrees produces chatter marks, the chamfered surface is scratched by the lateral surface of the lower carving knife, and the roughness is reduced. The lower carving knife comprises a knife carrier, two chamferingblades forming an included angle of 90 degrees and arranged at the ends of the knife carrier, and a groove carving blade, two corresponding clearance angles are correspondingly arranged on the lateral surfaces of the two chamfering blades, and the groove carving blade is arranged at the tips of the two chamfering blades and symmetrical with the two chamfering blades. The utility model has the characteristics that the lower carving knife has high rigidity, and that the carved groove and the chamfered surface accord with design requirements, and is mainly used for the lower carving knife for processing the reverser of the pulling motor on the lower carver.
Description
Technical field
The utility model 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
The purpose of this utility model 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 utility model 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 utility model 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 utlity model has down the characteristics that icking tool rigidity height, the groove that carves and chamfer surface quality adhere to specification.The utility model 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 utility model, 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.
