numbers

0 and 9, 1 and 8, 2 and 7, 3 and 6, 4 and 5 are respectively and correspondingly marked on the same boss 10, the width of each boss 10 is 11mm, the distance from the flange, close to one side of a marking line 13, of the boss 10 marked with the number 0 to the central line of the positioning block 2 is 10mm, and the central line is vertical to the side edge of the positioning block 2 where the boss 10 provided with the number 0 is located; when the side edge of the positioning block 2 where the boss 10 marked with adjacent numbers is positioned rotates to be aligned with the vertical surface provided with the size scale mark 7, the interval value of the boss 10 marked with the adjacent numbers is 1 mm; the vertical distance between the boss 10 marked with the number 0 and the marked line 13 on the slide block 5 and the flange close to one side of the marked line 13 is L, wherein L is n multiplied by 10mm, and n is an integer larger than 4.

The utility model provides a positioner novel structure, the structure seems simple but the practicality is strong, and it is also convenient to use, especially adapted workman's operation. Utilize the utility model discloses a positioner can realize the accurate positioning of arbitrary size length fast, size length here indicates the length value with the millimeter as the unit, and the door leaf is when producing, and the board size of cutting that needs to use also is accurate to the millimeter.

As shown in fig. 7, 752mm is taken as an example below to describe the operation principle of the present invention in detail, firstly, the side edge of the positioning block 2 of the boss 10 marked with the number 0 is adjusted to align with the vertical surface provided with the dimension scale mark 7, at this time, the vertical surfaces provided with the dimension scale mark 7 are vertically arranged on the flanges at the two sides of the boss 10 marked with the number 0, the plate 14 to be cut is placed on the vertical surface provided with the dimension scale mark 7 on the base 6, and then one end of the plate 14 to be cut is abutted against the flange of the boss 10 marked with the number 0. Here, 752mm is decomposed into 750mm +2mm to position the sheet, and firstly, it can be known that the vertical distance between the marking line 13 on the slider 5 and the flange of the boss 10 marked with the number 0 on the side close to the marking line 13 is L, and the scale value of the dimension scale mark 7 on the base 6 corresponding to the marking line 13 on the slider 5 is the actual dimension value, and in order to realize quick positioning, one end of the sheet 14 to be cut needs to abut against the flange of the boss 10 marked with the number 0. At this time, the rib of the boss 10 marked with the number 0 close to the side of the alignment mark 13 is corresponding to any dimension scale line 7 of the base 6, and if corresponding to the scale with the number M, the alignment mark 13 on the slider 5 is corresponding to the dimension scale line 7 of the base 6, and if the value is N, N is M-L, then we can conclude that if i want to achieve the positioning of 750mm by abutting one end of the sheet material 14 to be cut against the rib of the boss 10 marked with the number 0, then the alignment mark 13 of the slider 5 cannot correspond to 750mm, and should correspond to the position of 750-L, and if N is 1, L is 40mm, then the alignment mark 13 of the slider 5 should correspond to the position of 710, that is, one end of the sheet material 14 to be cut abuts against the rib of the boss 10 marked with the number 0, and then the slider 5 is made to slide in the chute 8 by the first positioning pin 4 assembly, when the pair of marked lines 13 on the slide block 5 is aligned with the scale lines 710 on the size scale lines 7 of the base 6, the length of the plate to be cut 14 is 750 mm.

It can be known from the above description that 750mm can be quickly positioned by the boss 10 marked with the number 0 of the positioning block 2, the alignment mark 13 on the slider 5, and the size scale mark 7 on the base 6, and directly abutting one end of the plate 14 to be sheared against the flange of the boss 10 marked with the number 0 is a value except for the single digit of the length of the plate 14 to be sheared, i.e. 750mm in this embodiment, and meanwhile, when L is 40mm, then the alignment mark 13 of the slider 5 should be aligned with the alignment mark 710 of the size scale mark 7 on the base 6, so as to play a role of auxiliary positioning.

Similarly, the hundred and ten digits of any three-digit number can be quickly positioned (the same reason of the four digits). It should be noted here that the reason why the minimum division value of the size scale lines 7 on the vertical surface of the base 6 is 10mm instead of 1mm is that if the minimum division value is 1mm, the number of the size scale lines 7 on the vertical surface is too large, the scale lines are too dense, and it is inconvenient for workers to realize quick positioning when shearing plates, and time is wasted; moreover, because the scale lines are too dense, the characters for marking numerical values are very small, and the positioning error and the cutting error of the sizes are very easy to occur, so that the waste of the plate 14 is caused; and the utility model discloses a minimum division value of size scale mark 7 is 10mm, and scale mark quantity is compared the division value and is 1 mm's size scale mark 7 significantly reduced, and the interval grow of adjacent scale mark 10 times, and the also corresponding grow of typeface of mark numerical value can be fast and accurate with on the slider 5 fix a position M-L's scale mark to marking line 13.

As shown in fig. 8, the following is to explain the single digit fast positioning method, which is also the key point of the present invention, that is, the structural arrangement of the boss 10 of the positioning block 2, the design of the boss 10 of the positioning block 2 is very delicate, and it can be known from the above description that: when the flange of the boss 10 marked with the number 0, which is close to one side of the alignment mark 13, is superposed with 750mm, the length of the plate 14 to be cut is 750 mm; the boss 10 marked with the number 0 is a rectangle which is convexly arranged on the side edge of the regular pentagon and has the width of 11mm, the distance from the flange, close to one side of the opposite marked line 13, of the boss 10 marked with the number 0 to the central line of the positioning block 2 is 10mm, and the central line is perpendicular to the side edge of the positioning block 2 where the boss 10 provided with the number 0 is located; when the side edge of the positioning block 2 where the boss 10 marked with adjacent numbers is positioned rotates to be aligned with the vertical surface provided with the size scale mark 7, the interval value of the boss 10 marked with the adjacent numbers is 1 mm; that is to say, the side edge of the positioning block 2 where the boss 10 marked with the number 1 rotates to align with the vertical surface provided with the dimension scale mark 7, the distance from the flange close to one side of the marking line 13 of the boss 10 marked with the number 1 to the center line of the positioning block 2 is 9mm, and so on, the distance from the flange close to one side of the marking line 13 of the boss 10 marked with the number 2 to the center line of the positioning block 2 is 8mm, the distance from the flange close to one side of the marking line 13 of the boss 10 marked with the number 3 to the center line of the positioning block 2 is 7mm, and the distance from the flange close to one side of the marking line 13 of the boss 10 marked with the number 4 to the center line of the positioning block 2 is 6 mm. Then, when the boss 10 marked with the number 1 rotates to the side edge of the positioning block 2 and rotates to be aligned with the vertical face provided with the dimension scale line 7, the boss 10 marked with the number 1 is equivalent to the boss 10 marked with the number 0 and moves backwards by 1mm, at the moment, one end of the plate 14 to be sheared abuts against the flange at one side of the boss 10 marked with the number 1, which is close to the alignment mark 13, namely, the plate 14 to be sheared moves backwards by 1mm on the basis of 750mm, and at the moment, the length of the plate 14 to be sheared is 751 mm.

Similarly, when the boss 10 marked with the number 2 rotates to the side edge of the positioning block 2 and is aligned with the vertical surface provided with the dimension scale line 7, the boss 10 marked with the number 2 is equivalent to the boss 10 marked with the number 1 and moves backwards by 1mm, at the moment, one end of the plate 14 to be sheared abuts against the flange at one side of the boss 10 marked with the number 2, which is close to the alignment mark 13, namely, the plate 14 to be sheared moves backwards by 1mm on the basis of 751mm, and at the moment, the length of the plate 14 to be sheared is 752 mm.

It is said here that we can easily find that the front surfaces of the five bosses 10 are respectively marked with

numbers

0, 1, 2, 3 and 4 in sequence, the back surfaces of the five bosses 10 are respectively marked with

numbers

5, 6, 7, 8 and 9 in sequence, the numbers respectively represent the size values of single digits, that is, when the flange of the boss 10 marked with the number 0 close to one side of the marking line 13 is superposed with 750mm, the length values of the hundred and ten positions of the plate 14 to be sheared are firstly determined to be 750mm, then the side edge of the positioning block 2 where the boss 10 marked with the number is located is directly rotated to be aligned with the vertical surface provided with the size scale line 7 according to the required single digit value, and then one end of the plate 14 to be sheared is abutted against the flange of the boss 10 marked with the number close to one side of the marking line 13 to complete the positioning of the required size.

Here, it is further required to explain an arrangement principle that the back surfaces of five bosses 10 are respectively marked with

numbers

5, 6, 7, 8 and 9 in sequence, and the following explanation is given by taking 758mm as an example, because the

numbers

0 and 9, 1 and 8, 2 and 7, 3 and 6, 4 and 5 are respectively correspondingly marked on the same boss 10, the widths of the bosses 10 are both 11mm, the distance from the flange close to the side of the marking line 13 of the boss 10 marked with the number 0 to the center line of the positioning block 2 is 10mm, when the unit number is 5, 6, 7, 8 and 9, the positioning block 2 needs to be turned over, that is, the front and back surfaces are reversed, when the flange close to the side of the marking line 13 of the boss 10 marked with the number 0 (at this time, the number 0 is on the back surface of the boss 10) is overlapped with 750mm, the distance from the flange close to the side of the marking line 13 of the boss 10 marked with the number 0 to the center line of the, at the moment, the front and the back of the positioning block 2 are exchanged, the distance from the flange, close to the side of the alignment mark 13, of the boss 10 marked with the number 0 to the center line of the positioning block 2 is 1mm, namely, the distance from the flange, close to the side of the alignment mark 13, of the boss 10 marked with the number 9 to the center line of the positioning block 2 is 1mm, at the moment, one end of the plate 14 to be sheared abuts against the flange, close to the side of the alignment mark 13, of the boss 10 marked with the number 9, namely, the plate 14 to be sheared moves backwards by 9mm on the basis of 750mm, and at the moment, the length of the plate 14 to be sheared is 759 mm.

Similarly, after the front and back of the positioning block 2 are exchanged, when the boss 10 marked with the number 1 (at this time, the number 1 is on the back of the boss 10) is close to the flange on one side of the alignment mark 13 and coincides with 750mm, the distance from the flange on one side of the alignment mark 13, close to the center line of the positioning block 2, of the boss 10 marked with the number 1 is 2mm, namely the distance from the flange on one side of the alignment mark 13, close to the center line of the positioning block 2 is 2mm, at this time, one end of the plate 14 to be sheared abuts against the flange on one side of the boss 10 marked with the number 8, close to the alignment mark 13, namely the plate 14 to be sheared moves backwards by 8mm on the basis of 750mm, at this time, the length of the plate 14 to be sheared is 758 mm.

Similarly, the principles of the quick positioning dimensions of the bosses 10, referenced 5, 6, 7, are not described in detail.
