short latch

62,63 is all screw configuration, but so the operator its extension elongation spiral shell is transferred to fine setting.In the present embodiment, the angle of cutting type tooth 106 uses when spending long latch 62 to locate if be less than or equal to 90, then adopts short latch 63 (being described further again after its reason appearance) when spending greater than 90 as if cutting angle.

More than be each assembly of tooth cutter of the present invention the be associated structure and the general introduction of position.

The present invention must finish previous operations earlier before cutting key 100 type teeth 106.At first, mounting cutter 16 in cutter shaft 15, utilize slip gauge (gage) to be placed on the platform 22, can set cutter 16 terminal alignment stock 1 turning centre height fast with calibrated altitude.Then, stock 1 is penetrated balance bracket 25, stock 1 front-end driven end 103 is inserted in the tool 36 type holes 361, rear end lever 101 partly is subjected to clamping device 40 swivel heads 41 crampings, so fixedly stock 1 (as shown in Figure 8) on platform 22.Before cutting, the essential combination of understanding the inner video disc of core (disk) earlier of operator, just know and to scribe which kind of number of teeth and angle to key 100 type teeth 106, the dealer can obtain the correct number of teeth of key and angle information via the core numbering of computer system, below just be example with 045-081-117-153-009-045-117-153-018, its key 100 type teeth 106 numbers have nine teeth, the first type tooth 106 (I) is 45 degree, the second type tooth 106 (II) is 81 degree, the 3rd type tooth 106 (III) is 117 degree, and the rest may be inferred for remaining type tooth angle degree.

Then, again process operation of the present invention is described in detail as the back:

When the operator will be to stock 1 cutting type tooth 106, at first be noted that the cutting angle of stock 1 type tooth 106 and the tooth distance of positions from, cutting angle is controlled by rotating index dial 32 (R axle), and the tooth distance of positions is from then being controlled by rotating class's wheel 51 (Z axles).The cutting of each type tooth 106 all is after adjusting angle and tooth position, and control is changed hands wheel 24 length feeds (X-axis) finishing the cutting behavior again, below is just described in detail at the stock removal action of single type tooth 106; Seeing also shown in Figure 9ly, when wanting cutting type tooth 106, is example with first type tooth 106 (I) miter angle, and at first 32 rotations of switching index dial are positioned at 45 degree, and this tool 36 promptly drives stock 1 rotation makes the cutting limit 105 of stock 1 become miter angle with horizontal line.Again referring to shown in Figure 10, first type tooth 106 (I) cutting angle is less than 90 degree, therefore operator's control rotary disk 61 is turned alignment stage 22 upper limbs with long latch 62, and then the operator rotates handwheel 24 again and drives platform 22 vertical (X-axis) feedings, cutter 16 promptly begins the cutting limit 105 of stock 1 is eliminated, when platform 22 edges support to end to long latch 62, the amount of feeding of cutter 16 was just located and is terminated on the center of stock 1, avoids cutter 16 to cut the true edge 104 of stock 1 whereby by mistake.Then, control is changed hands wheel and 24 is made platform 22 return back to original position again, so promptly finishes the stock removal action of a type tooth 106, if error is arranged before and after the length feed amount of platform 22 slightly, can transfer long latch 62 extension elongations to achieve a solution by spiral shell.

See also shown in Figure 11, when the operator will cut down one type tooth 106, at first be noted that when each index dial 32 carries out angle adjustment and set before next lattice type tooth 106 angle, must forward 0 degree position earlier to and make flyback action, so as to eliminating the progression tolerance of index dial 32.Then, with cutting stock 1 the 3rd type tooth 106 (III) is example, the 3rd type tooth 106 (III) angle is 117 degree, therefore rotating index dial 32 earlier makes stock 1 go to 117 degree positions, because this angle is greater than 90 degree, therefore operator elder generation control rotary disk 61 makes short latch 63 turn alignment stage 22 upper limbs, when by vertical stroke of short latch 63 locating platforms 22, whole displacement can extend, make the amount of feeding of cutter 16 can arrive another side of stock 1, so just can cut the 3rd type tooth 106 (III) fully and become 117 degree, these type tooth 106 angles just of the present invention are less than or equal to 90 degree and adopt long latch 62, adopt the reason of short latch 63 greater than 90 degree.All the other various teeth 106 cut according to this principle, get final product the angle that cutting goes out key 100 all models teeth 106.

Next, the present invention except cutting type tooth 106 angles, the tooth distance of positions of the various tooth 106 of also essential control from.Tooth position controlling organization 50 promptly is to aim at control cutting teeth position and being provided with, it utilizes the direction springing to the left of whole workbench 20, turn class's wheel 51 each grade step surfaces 511 and be subjected to attachment piece 52 contacts, can make stock 1 segment displacement be subjected to cutter 16 cuttings, so can go out multiple tracks type tooth 106 along stock 1 axial cutting.But the present invention more specifically is, this class's wheel 51 can utilize two groups of fan-shaped slip gauges 53 of different-thickness, be separately positioned on the two adjacent step surfaces 511, the formed fixing small jump by two fan-shaped slip gauges, 53 planes, 16 pairs of same type teeth 106 of control cutter repeat to cut wide action, and make the encryption behavior that tooth pitch is widened, and, the fan-shaped slip gauge 53 of installing can be done to change and adjust on the class of the present invention wheel 51, makes the size of cutting wide encryption have more elastification.Below, adjustment action with regard to tooth of the present invention position is described in detail, wherein, the full-height tooth of present embodiment GENERAL TYPE tooth 106 adopts 1.5mm apart from (d), and the object of encrypting is an example with the second type tooth 106 (II), and its encryption tooth pitch (d ') be assumed to be 0.5mm, make the tooth pitch summation of the second type tooth 106 (II) become 2.0mm, and except having the fan-shaped slip gauge 53 of standard thickness (W=5mm), also need to use another kind and have another the fan-shaped slip gauge 55 that adds scantling (W ').

See also shown in Figure 12, at first, when carrying out the cutting of stock 1 first type tooth 106 (I), the operator turns index dial 32 makes stock 1 go to 45 degree, make class take turns 51 first step faces 511 (I) again over against contact top stopping bar 523, fan-shaped slip gauge 53 on the first step face 511 (I) is subjected to top stopping bar 523 contacts location, what first step face 511 (I) was gone up use is the fan-shaped slip gauge 53 of standard thickness (W), whole workbench 20 can be displaced to left on the fixed position, this moment, the position of cutter 16 should so can go out the first type tooth 106 (I) to stock 1 cutting just over against stock 1 first type tooth 106 (I) position.If this moment, the position of the cutter 16 alignings first type tooth 106 (I) had error slightly, can transfer stopping bar 523 extension elongations in top to achieve a solution by spiral shell, because cutter 16 external diameters are 1.5mm with full-height tooth apart from (d), therefore the first type tooth 106 (I) is to cut into full-height tooth apart from (d).

See also shown in Figure 13ly, then carry out the cutting of the second type tooth 106 (II).Adjust stock 1 angle earlier and go to 81 degree, turn class again and take turns 51 second step faces 511 (II) over against contact top stopping bar 523, fan-shaped slip gauge 53 on the second step face 511 (II) also is a standard thickness (W), therefore turn to second step face 511 (II) and can make 1 of stock be moved to the left a full-height tooth apart from (d), so cutter 16 can be done primary stock removal action to stock 1 second type tooth 106 (II).

Because above-mentioned action only to the second type tooth 106 (II) cutting 1.5mm, also needs to cut wide 0.5mm as encryption again, therefore need do stock removal action for the second time again to the second type tooth 106 (II).Be noted that this moment, it is immutable that stock 1 will maintain original angle, rotate class and take turns 51 the 3rd step surfaces 511 (III) over against contact top stopping bar 523, the 3rd step surface 511 (III) is if add the fan-shaped slip gauge 53 of standard thickness (W), will make stock 1 move to left a full-height tooth apart from (d=1.5mm), d '=0.5mm and the size that the second type tooth 106 (II) is widened only need move to left, therefore the essential fan-shaped slip gauge 55 that adopts another kind of thickness specification, the formula of applying mechanically of its thickness (W ') is the difference that " thickness of preceding single order secter pat rule " add " full-height tooth apart from " and " encrypting tooth pitch ", just W '=W+ (d-d ') can get W '=5+ (1.5-0.5)=6mm after calculating.See also shown in Figure 14, when the operator turns the 3rd step surface 511 (III) over against contact top stopping bar 523, the encryption thickness of another fan-shaped slip gauge 55 (W ') can make 1 mobile 0.5mm of stock, so 16 pairs second type teeth 106 of cutter (II) can repeat to cut wide 0.5mm, and finish the secondary stock removal action of the second type tooth 106 (II), make the last actual tooth pitch of the second type tooth 106 (II) become 2.0mm.

See also shown in Figure 15, cutting the 3rd type tooth 106 (III) and then.Adjust stock 1 angle earlier and go to 117 degree, rotate class again and take turns 51 the 4th step surfaces 511 (IV) over against contact top stopping bar 523, if the 3rd type tooth 106 (III) is to adopt full-height tooth apart from (d), then the fan-shaped slip gauge of being installed on the 4th step surface 511 (IV) 55 is the thickness (being W ') of identical preceding single order secter pat rule 55.If the 3rd type tooth 106 (III) also is to make the encryption tooth of cutting wide tooth pitch, then after the 4th step surface 511 (IV) is finished cutting full-height tooth distance (d), apply mechanically formula according to above-mentioned thickness, the fan-shaped slip gauge thickness W that the 5th step surface 106 (V) is adopted "=W '+(d-d "), wherein d " is that the 3rd type tooth 106 (III) will be cut wide size; principle is gone down according to this, can cuts the different type teeth 106 of encrypting tooth pitch.

The present invention repeats to cut wide one by certain ad hoc type tooth 106 and encrypts tooth pitch (d ') with as encryption, it is imitated that whole key 100 structures are difficult for more, present embodiment d ' is example with 0.5mm, certainly this size can freely increase and decrease change by the dealer, as 0.2,0.3,0.5mm or the like, the stranger can't peep and know its data.More than be the operational means of class's wheel 51 with a certain type tooth 106 of continuous step surface 511 special cuttings, its purpose is the tooth pitch of widened tooth 106, imitated this key 100 is the shape difficulty more, and these means just are not used in single tooth, the dealer can select the type tooth 106 of optional position, arbitrary number to bestow this kind encryption measures, even other people know the angle of key 100 various teeth 106, but if do not know that as to encrypt tooth and cut wide size (d ') what are, be to unblank equally, make anti-theft effect of the present invention can reach the effect that doubles.

See also shown in Figure 16, after finishing, 106 cuttings of key 100 all models teeth can produce burr, the operator is as long as taking out key 100, key 100 axles 102 ends are inserted in socket 17 any one hole 171, but socket 17 be provided with a plurality of holes 171 not only Key 100 insert from either direction, and can allow socket 17 have more heat-sinking capability, the key 100 after the insertion can contact with the plastic roller brush 172 in the rotation, so can remove burr easily apace.

In addition, the present invention has the ability of the microscler key of cutting, see also shown in Figure 17, one microscler stock, 2 two ends are subjected to tool 36 and swivel head 41 clampings, though microscler stock 2 has longer axle and since balance bracket 25 can about adjust to move, so as to changing the position of the strong point, so can firmly suitably support microscler stock 2, help the carrying out of son cutting.

Tooth cutter of the present invention has solved the technical problem that general tooth cutter can't be made the solid curve Key structure.This tooth cutter has the control of R axle, Z axle and X-direction changes ability, and it mainly is provided with: an angle control mechanism 30, and can do the transfer of R direction of principal axis, but, so can control the cutting angle of stock 1 type tooth 104 by index dial 32 start stocks 1 rotation predetermined angular; One tooth position controlling organization 50 can move as Z-direction, can control the tooth position of stock 1 cutting by class's wheel 51; And a feeding controlling organization 60 can be located the amount of movement of X-direction, when making cutter 16 cutting stocks 1, can arrive predetermined feeding depth respectively.Promptly has the ability of cutting type tooth 106 by above three groups of controlling organizations, and can produce key 100 structures with solid curve shape, add that the present invention can apply mechanically the technology of encrypting tooth, the key 100 that manufacturing of the present invention is come out has more the effect that is difficult to copy.
