Α7 Β7 V. Description of the invention () ^ After the tooth position, 'the control handwheel 24's longitudinal feed (X | i) is completed to complete the cutting row', ..., == The following describes the cutting action of a single tooth i06 in detail ; Please refer to the ninth figure, when the profile tooth 106 is to be cut, taking the first profile tooth at a 25 degree angle as an example, first turn the index plate 32 to rotate and position it at 4 $ degrees, which ~ 8 3 6 That is, the moving blank 丨 rotates so that the cutting edge of the blank ^ $ forms a 45 degree angle with the horizontal line, and as shown in the tenth figure, the cutting angle of the first tooth ι〇6 (ι) is less than 90 degrees. Therefore, the operator controls the turn to align the long stop pin _ to the upper edge of the flat ° 22, and then the operator rotates the hand wheel 24 to drive the platform 22 longitudinally (by X car), and the cutter 16 starts to feed the blanker. The cutting order is removed. When the edge of the platform 22 abuts on the long stop pin, the feed amount of the cutter 16 is positioned at the center of the blank 丨, thereby avoiding the tool 丨 6 to cut the blank to the blank. The edge 104 ′ then controls the handwheel 24 to return the platform 22 to the original position, so that the cutting action of the profile tooth 106 is completed. If the longitudinal feed of the platform 22 is slightly before and after If there is an error, it can be solved by adjusting the extended length of the stopper pin 62. Please refer to the eleventh figure for the line. When the operator wants to cut the next pattern return 106, the first thing to note is that each time the indexing plate 32 is adjusted to set the angle of the next grid tooth 106, It is necessary to first turn to the 0 degree position = zeroing action to eliminate the progressive tolerance of the index plate 32. Then, take the second tooth i06 (m) of the cutting blank 1 as an example, and the third tooth 106 ( m) The angle is 11 7 degrees, so first turn the index plate 32 to turn the blank 1 to the i 丄 7 degree position. Because the angle is greater than 90 degrees, the operator first controls the turn plate 61 to turn the short stop pin 63 to the right position. The upper edge of the quasi-platform 22 should be positioned by the short stop pin 63. During the vertical stroke, the entire moving distance will be lengthened, so that the feed amount of the cutter 16 can be page 13 > The paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm 501961 A7 B7) Printed by the employee's consumer cooperative V. Description of the invention (12) Reached the other side of the blank 1, so that the third type tooth 10 6 (melon) can be completely cut to 1 1 7 degrees, which is also the tooth of the present invention The reason why the 106 angle is less than or equal to 90 degrees is to use the long stop pin 6 2 and the greater than 90 degrees is to use the short stop pin 6 3 'The remaining types of teeth 1 06 are cut in accordance with this principle, and all keys 100 can be cut. The angle of the profile tooth 106. Next, in addition to cutting the profile tooth angle 106, the present invention must also control the tooth distance of each profile tooth 106. The tooth position control mechanism 50 is specifically designed to control cutting The tooth position is set. It uses the entire table 20 to bounce to the left, and each step surface 511 of the turning wheel 51 is abutted by the top stopper 52, which will cause the blank 1 to be displaced in stages by the tool 16 and cut. It can be cut along the axial direction of the blank 1 to form a multi-channel tooth 106, but the present invention is more special The level wheel 51 can use two sets of sector block gauges 5 3 of different thicknesses, which are respectively arranged on two adjacent step surfaces 511, and the tool is controlled by a fixed small step formed by the planes of the two sector block gauges 53. 16 Repeat the widening action on the same type of tooth 106 to make the encryption action of widening the tooth pitch 'and' the sector block gauge 53 installed on the class wheel 51 of the present invention can be replaced and adjusted. ' The size is more flexible. The adjustment of the tooth position of the present invention is described in detail below.
