Abstract
A cutting method for coil conductor in which a halted conductor to be formed into a coil is severed by means of cutting edges while feeding the cutting edges downstream along the feeding direction of the coil conductor. Thus a pushing back force against the coil conductor dose not occur and deformation of the coil conductor is prevented when cutting the coil conductor, whereby the dimensions of the coil conductor is stabilized.
Description
The present invention relates to for example to can be used for the cutting method and the cutter sweep of coil-conductor (Coil Conductor) of the armature coil of engine primer.
Fig. 7 has showed the sort of structure that is used for a kind of traditional cutter sweep of coil-conductor that discloses briefly in Japan Patent No 62-48471.In this figure, the coil-conductor with circular cross-section 2 that is stored in the bobbin 1 is extracted a predetermined quantity by push rolls 3 from bobbin 1, and is sent to worker station.Insulating barrier on the conductor outer peripheral face in the long scope of 2L is peelled off it with spiral reamer 4, uses cutoff tool 5A then, 5B with coil-conductor 2 in the cut-out of the center of 2L scope.So just as shown in Figure 8, cut coil-conductor 2 respectively has one section L length to be peelled off its insulating barrier at its two ends.And, the coil-conductor of being extracted from bobbin 12 by alignment roller 6 with its alignment.
The shape that cut coil-conductor 2 forms as shown in Figure 9, among the groove 7a with it insertion one armature core 7, its situation as shown in figure 10 then.Afterwards as shown in figure 11, coil-conductor 2 has just formed the part of passing armature core 7, and has this that peel off insulating barrier and partly be connected to commutator 8.By this way, the armature that is used for engine primer has just assembled.
Figure 12 has showed briefly by the used cutting method of device shown in Figure 7.One end of coil-conductor 2 is caught so that it is sent to a gripper.Cutoff tool 5A, 5B are respectively by cutting off the eccentric cam 10A of mechanism, 10B and driving shaft 11A, 11B connection.By the 10A of eccentric cam mechanism, 10B, driving shaft 11A, the rotation of 11B is converted into cutoff tool 5A, and the linearity of 5B moves.
Figure 13 is an enlarged drawing of showing the coil-conductor 2 cutting situations among Figure 12. Cutoff tool 5A, 5B moves so that conductor 2 is cut off along the direction perpendicular to the feeding direction of coil-conductor 2.And at each cutoff tool 5A, the nose angle on the 5B is 90 °, and its reason is that the both ends of the coil-conductor 2 after the cut-out can be inserted among the groove 7a of armature core 7 reposefully.
In the cutting method of aforesaid traditional coil-conductor 2, although in the 2 cut whiles of coil-conductor, conductor 2 is sent to the worker station, but because cutoff tool 5A, 5B moves along the direction perpendicular to conductor 2, be positioned at cutoff tool 5A, the tool surface that the conductor 2 of 5B party upstream is cut off cutter is pressed to the direction opposite with its feeding direction.At this moment since conductor 2 along and its send opposite direction to mobilely be sent to roller 3 restrictions, coil-conductor 2 is deflection as shown in Figure 13, its result can make coil-conductor 2 become curved or make cut-out after the size of conductor 2 inapplicable.And, have a pressure from coil-conductor 2 and put on cutoff tool, make cutoff tool 5A, 5B weares and teares or sends noise.
On the other hand, although the coil-conductor 2 of cutoff tool downstream side when being cut along its feeding direction pushing can not produce any trouble because gripper 9 does not hinder along the moving of feeding direction of coil conductor 2.
In order to address the above problem, one object of the present invention just provides a kind of coil-conductor cut direction and cutting equipment that prevents the coil-conductor distortion.
In one aspect of the invention, the cutting method that is used for coil-conductor has the following step: after sending a predetermined length to coil-conductor is stopped; When carrying over the coil-conductor downstream direction and sending cutoff tool to, cut off the coil-conductor that has stopped with cutoff tool.
In another aspect of the present invention, a kind of cutter sweep that is used for coil-conductor has: have the cutting mechanism that is used at the cutoff tool that is sent to the coil-conductor cutting that stops behind the scheduled volume; And the feed mechanism of with cutting mechanism sectioned coil conductor the time, cutoff tool being sent to along coil conductor downstream direction.
In another aspect of the present invention, a kind of cutter sweep that is used for coil-conductor has: be used for and will send the cutoff tool of the coil-conductor cutting that has stopped after the scheduled volume to, be used for when the sectioned coil conductor along the oblique guiding cutoff tool of coil conductor downstream direction, along the guide member of oblique placement; And the driving mechanism that moves cutoff tool along guide member.

Introduce one embodiment of the present of invention below in conjunction with accompanying drawing.Fig. 1 is a sketch that shows the cutting method of the one embodiment of the present of invention that are used for coil-conductor.Fig. 2 is in the enlarged drawing of the state of being cut for the coil-conductor in the exploded view 1.
In these accompanying drawings, make cutoff tool 5A, 5B carries out the cutting eccentric cam 10A of mechanism of cutting operation, and 10B links mutually, and can make it respectively along driving shaft 11A, and 11B moves simultaneously.Make the cutting eccentric cam 10A of mechanism, 10B is along driving shaft 11A, and the crank mechanism 12 of sending to of 11B motion is connected in driving shaft 11B by a cover bevel gear 13,14.
Cutting mechanics is normally by cutoff tool 5A, and 5B cuts eccentric cam machinery 10A, 10B and driving shaft 11A, and 11B forms, and feed mechanism is generally by sending crank mechanism 12 and bevel gear 13,14 formations to.
In the present embodiment, cutoff tool 5A, 5B is cut off coil-conductor along giving in the moving of direction direction at 45 with coil-conductor 2 at it.In other words, as shown in Figure 2, each cutoff tool 5A, the nose angle of 5B are 90 °, when coil-conductor 2 is cut, make cutoff tool 5A, and 5B moves along the tool surface of cutting on the upstream side of coil conductor 2.
Therefore, the anti-power that pushes away coil-conductor 2 can not appear when cutting, thereby, the distortion of conductor 2 is prevented, thereby make the dimensionally stable of coil-conductor 2.And, there is not thrust to put on cutoff tool 5A by coil- conductor 2,5B has prevented reamer wearing and tearing or cutoff tool 5A therefrom, 5B produces noise.
Should be noted that though cutoff tool 5A, the angle of sending to of 5B is set up to 45 ° in example shown in Figure 2, make it to send to also and be fine along 60 ° of angles in the example as shown in Figure 3.This angle is greater than the angle between tool surface and the coil-conductor 2.Though, compare with example shown in Figure 2, have a big slightly pressure coil-conductor 2 is added, when comparing, can prevent the distortion of coil-conductor 2 with traditional approach shown in Figure 13.In addition, also can transmit cutoff tool along a kind of angle direction less than angle between tool surface and the coil-conductor 2.But, as this angle adjustment of sending to must be equaled angle between tool surface and the coil-conductor 2, just do not have unhelpful thrust or pulling force is applied on the coil-conductor 2,, thereby can obtain a level and smooth cutting surface owing to excessive sending to prevented the increase of spacing.
In addition, Fig. 4 has showed an example, uses the cutoff tool 5C with 60 ° of nose angles in this example, 5D, and its feed angle is adjusted to 70 °, and the various variations of nose angle and feed angle can be arranged by this way.
In addition, not only place restrictions in circle in the cross section of coil-conductor 2, for example, can also be rectangle.But, also can cut though have the conductor of square-section with shearing force, the conductor 2 with circular cross-section must utilize the cutoff tool 5A with triangle cutting edge, 5B cutting, and to employing the present invention effective especially.
Now carefully introduce the structure of cutter sweep of the present invention.Fig. 5 is a cutaway view of showing cutter sweep detailed structure shown in Figure 1.In the figure, at driving shaft 11A, dispose along its axially extended slide key 21A 21B on the 11B respectively.Driving shaft is parallel to each other, and is connected on the unshowned pedestal, so that they can not move vertically.
One eccentric cam body 22 is connected to driving shaft 11A and goes up so that make it along this slippage.And eccentric cam body 22 rotates with axle 11A.Eccentric cam body 22 is contained in the shell block 23, and allowable offset cam body 22 is disposed between shell block 23 and the cam body 22 at the needle bearing 24 that shell block 23 transfers are employed.A connection piece 26 usefulness pins 25 are connected with shell block 23, and cutting eccentric cam mechanism comprises eccentric cam body 22, shell block 23, needle bearing 24, pin 25 and connector 26.
One end of connector 26 is inserted in the spring base 27, and a slip adjustment part 28 and a disc spring 29 are placed in the spring base 27.Cutter adjustment rack 30 adjacent to spring base 27 is pushed by disc spring 29.One cutter adjustment wedge 31 is disposed at cutter adjustment rack 30 and is used between the cutoff tool clamper 32 of clamping cutoff tool 5A.
By needle bearing 34, lid 33 is configured in two ends vertically of eccentric cam body 22.The a pair of side plate that faces with each other 35,36 is connected to and covers on 33, and the connector that is connected between eccentric cam body 22 and the cutoff tool 5A then is contained between the side plate 35,36.37 of slide blocks place respectively between side plate 35,36 and the cutting tool gripper 32.
Because the mechanism that cutoff tool 5B is installed on the driving shaft 11B is identical with the structure that cutoff tool 5A is installed, so will omit its explanation.
By rod end bearing 56, bar 55 is connected in staged pin 54 with rotary way.By swivel pin 58 and rod end bearing 59, pin clamper 57 is connected in rod end bearing 56.Pin clamper 57 is fixed in side plate 35.
Send crank mechanism to and comprise axle 51, eccentric shaft 52, Power Lok53, staged pin 54, bar 55, rod end bearing 56, pin clamper 57, swivel pin 58 and rod end bearing 59.
In aforesaid cutter sweep, by rotating driveshaft 11A, 11B, cutoff tool 5A, 5B just move and sectioned coil conductor 2 along left and right direction respectively as shown in Figure 5.Meanwhile, bevel gear 14 is rotated with driving shaft 11B, so that rotating bevel gear 13 and axle 51.Along with the rotation of axle 51, bar 55 just moves as shown in Figure 5 along the vertical direction, thus side plate just by pin 58 and pin clamper 57 edge upper and lowers as shown in Figure 5 to moving.
Because side plate 35 is arranged on two cutting eccentric cam 10A of mechanism, between the 10B, so cam mechanism 10A, 10B and cutoff tool 5A, 5B just do as a whole along driving shaft 11A, the 11B motion.Therefore, by suitably adjusting cutting cam mechanism 10A, the offset of the eccentric cam body 22 of 10B and send the offset of the staged pin 54 of crank mechanism 12 to, cutoff tool 5A, the cutting operation of 5B just can be adjusted in advance and reach make it operation synchronized with each other the duty cycle of cycle and bar 55.Can realize cutoff tool 5A as shown in Figure 1 thus, 5B sends operation to.
In order to reach the left and right cutting eccentric cam 10A of mechanism, the center that clamper 57 is preferably disposed on close side plate 35 is sold in the 10B balance exercise, and side plate 35 serves as the cutting eccentric cam 10A of mechanism, the parts that connect between the 10B.
In addition, though in the above-described embodiments, cutting operation is mechanically to link by bevel gear 13,14 with sending operation to, and this linking also can provide with other mechanism.And, control cutting operation and send operation to electric means, also can make these operation coordinated movements of various economic factors without mechanical link mechanism.
Fig. 6 is the sketch map of cutter sweep that is used for the another embodiment of the present invention of coil-conductor.In this figure, cutoff tool 60A, 60B is by the cylinder 61A as guide and two kinds of functions of driving mechanism, 61B is driving, direction under the relative winding wire 2 in edge is oblique is relatively moved, and just by these two the cutoff tool 60A with 90 ° of nose angles, 60B finishes cutting operation, cylinder 61A, each relative coil-conductor 2 angle at 45 of 61B are provided with.
Because cutoff tool 60A, 60B are directly from cylinder 61A, 61B receives driving force, so the structure of this sampling device is simple.
