Abstract
The utility model discloses a cutter frame structure of a double-shaft double milling cutter of a slot milling machine of a commutator, which comprises a cutter base body (1). A driving gear set (2) is arranged inside the cutter base body, and a left cutter bar (7) and a right cutter bar (13) are arranged inside the driving gear set (2). Front bearings (8), middle bearings and back bearings (9) are sequentially arranged at the lateral sides of the left cutter bar and the right cutter bar. Left milling cutters (5) and right milling cutters (12) are respectively arranged between the front bearings and the middle bearings and on the left cutter bar and the right cutter bar. The front bearings and the back bearings are respectively located inside a left sealing plate (10) and a right sealing plate (11). The left milling cutter and the right milling cutter are both double milling cutters or single milling cutters. The left cutter bar and the right cutter bar move on a straight line stably and reliably all the time. A hook groove (or a groove between sheets of a commutator sector) at the position of a hook of the commutator can be cut in one step, thereby improving working efficiency. The cutter frame structure further adopts double-bar rotating cutting, thereby enabling cutting of the hook groove of the commutator (or the groove between the sheets of the commutator sector) to be faster and more stable and enabling the commutator industry to have high efficiency, good quality and low cost and to save resources.
Description
Technical field
The present invention relates to a kind of engine commutator slotter, specifically relate to a kind of milling cutter cutter frame mechanism of engine commutator slotter.
Background technology
At present, base components is a copper type body part (being commutator segment) in the commutator that motor is used (commutator) structure, it in structure with orderly cylindrical arrangement, have up and down directionality distinguish and copper body and copper body between the insulating properties relation, requiring has hook, groove isolation to separate between copper sheet and copper sheet.Groove milling post in the commutator industry manufacturing process is the important step of commutator production link, it is divided into two kinds of grooves: the hook groove (promptly milling the width of outer hook) between hook and the outer hook outside groove, the crotch place between the commutator segment of commutator and the sheet between the commutator segment, all require position relation, size between groove and the groove very important, degree of difficulty is higher relatively in manufacture process, so the slotter with high accuracy, high benefit solves this production problem in the industry operation.Precision often is not very high in existing slotter, its structure adopts single shaft hilted broadsword cross cutting, unhappy, the poor stability of cutting speed, in the cutting Chang Fashengqie partially, cut phenomenon such as big (promptly normal generation trough mills partially in the groove milling process, groove mills phenomenons such as wide), give and bring in the industry that benefit is not high, quality is difficult for assurance, causes the wasting of resources, cost to be difficult to problems such as reduction.
Summary of the invention
(1) technical problem that will solve
The present invention be directed to the deficiencies in the prior art, and the two milling cutter cutter frame mechanisms of the twin shaft that a kind of commutator slotter is provided, unhappy, the poor stability of cutting speed in the solution industry, precision is not high, benefit is not high, quality is difficult for guaranteeing, causing the wasting of resources, cost to be difficult to problems such as reduction.
(2) technical scheme
The technical solution adopted for the present invention to solve the technical problems is: the two milling cutter cutter frame mechanisms of a kind of twin shaft of commutator slotter, comprise the tool rest main body, in described tool rest main body, driving gear set is housed, left knife bar and right knife bar are housed in this driving gear set, side at left knife bar and right knife bar all is equipped with fore bearing successively, middle (center) bearing and rear bearing, on left knife bar and right knife bar, and between fore bearing and middle (center) bearing, locate to be equipped with separately respectively left milling cutter and right milling cutter, fore bearing and rear bearing are positioned at left shrouding respectively separately, in the right shrouding, left shrouding, right shrouding is connected with the tool rest main body respectively.Described left milling cutter and right milling cutter are two milling cutters or single cutter.
(3) beneficial effect
The two milling cutter cutter frame mechanisms of the twin shaft of commutator slotter of the present invention compared with prior art, have following beneficial effect:
The present invention adopts two milling cutter (or single cutter) the formula structures of twin shaft, in the tool rest main body, left side shrouding, adopt three groups of bearings to come carries left separately on the right shrouding, right knife bar, utilize " sight alignment " principle, make a left side, right knife bar is steadily operation reliably point-blank all the time, arrive a left side through the driving gear set transferring power, an on the right knife bar and drive left side, right milling cutter rotates at a high speed and can't produce beat, two groups of knife bars about in the tool rest main body, being equipped with simultaneously, about install separately again on two groups of knife bars about two two (or single) milling cutters, the disposable commutator crotch place hook groove (or between the commutator segment sheet groove) that cuts out, increase work efficiency, also adopt two bar rotary cuttings, cutting commutator hook groove (or between sheet groove) speed is faster.
With 24 of engine commutators is example, the milling cutter cutter frame mechanism cutting slot of tradition commutator slotter will be cut the processing of just finishing part for 24 times, and the two milling cutter cutter frame mechanism cutting slots of the twin shaft of commutator slotter of the present invention only need be cut the processing that just can finish part for 12 times, improve 1 times on the speed.The two milling cutter cutter frame mechanisms of the twin shaft of commutator slotter of the present invention only are applied on the even number sheet engine commutator, thereby give that the commutator industry is brought benefit raising, quality assurance, economized on resources, cost reduction etc.
Description of drawings
Fig. 1 is the front view of the two milling cutter cutter frame mechanisms of twin shaft of commutator slotter of the present invention.
Fig. 2 is the vertical view cutaway drawing of Fig. 1.
The specific embodiment
The present invention is described in further detail with embodiment with reference to the accompanying drawings.
As Fig. 1, shown in Figure 2, the two milling cutter cutter frame mechanisms of the twin shaft of commutator slotter of the present invention, comprise tool rest main body 1, in described tool rest main body 1, driving gear set 2 is housed, left knife bar 7 and right knife bar 13 are housed in this driving gear set 2, side at left knife bar 7 and right knife bar 13 all is equipped with fore bearing 8 successively, middle (center) bearing and rear bearing 9, on left knife bar 7 and right knife bar 13, and between fore bearing and middle (center) bearing, locate to be equipped with separately respectively left milling cutter 5 and right milling cutter 12, fore bearing 8 and rear bearing 9 are positioned at left shrouding 10 respectively separately, in the right shrouding 11, left shrouding 10, right shrouding 11 is connected with tool rest main body 1 respectively.
