[0092] The tenth bracket of the device for sawing the coupling blank sample in the lateral single-face direction is provided

[0093] Combined Figure 1 And Figure 4 As shown in the front view structural schematic diagram of the device, in order to facilitate the description, the four tenth brackets 10 are defined as ①, ②, ③ and ④, respectively. Since the eight second bearing segments 1003 of the four tenth brackets 10 located in the eight tenth holes 804 of the four eighth brackets 8 are not only positionally changed in the vertical direction, but also positionally changed in the horizontal direction, the eight second bearing segments 1003 located in the eight tenth holes 804 are all driven shafts. In contrast, since the other eight second bearing segments 1003 located in the eight sixth holes 405 of the four fourth brackets 4 are only positionally changed in the vertical direction, but not positionally changed in the horizontal direction, the other eight second bearing segments 1003 located in the eight sixth holes 405 are all driving shafts, which are defined as O.

[0094] As shown in Figure 1 Suppose that initially the four tenth brackets 10 are all vertically arranged, and after simplification, as shown in Figure 35As shown in the figure, along the four said main shaft O, said ① and said ③ simultaneously swing an angle along the clockwise direction, said ② and said ④ simultaneously swing the same angle along the counterclockwise direction, then four said tenth support 10 are in inclined setting, when this angle is exactly 90 degrees, then four said tenth support 10 are in horizontal setting, as shown in the figure, Figure 4 As shown in the figure, the swing direction of four said tenth support 10 is defined as positive direction;

[0095] As shown in the figure, Figure 4 Suppose initially four said tenth support 10 are in horizontal setting, after simplification, as shown in the figure, Figure 36 As shown in the figure, along the four said main shaft O, said ① and said ③ simultaneously swing an angle along the counterclockwise direction, said ② and said ④ simultaneously swing the same angle along the clockwise direction, then four said tenth support 10 are in inclined setting, when this angle is exactly 90 degrees, then four said tenth support 10 are in vertical setting, as shown in the figure, Figure 1 As shown in the figure, the swing direction of four said tenth support 10 is defined as reverse direction.

[0096] The setting rule of the swing direction of the sixth support of the device for sawing the coupling blank sample in the lateral single-face sawing

[0097] As shown in the figure, Figure 3 Based on the top view structural schematic diagram of the device, in order to simplify the operation, the two said sixth supports 6 in front position will participate in the work, and the two said sixth supports 6 in rear position will not participate in the work, only play a balancing role; in order to facilitate the description, the two said sixth supports 6 in front position are defined as ⑤ and ⑥ respectively, four first bearing sections 603 of the two said sixth supports 6 are swing shafts, and are defined as Q;

[0098] Suppose initially the said sixth support 6 in left front position is in leisure state, after simplification, as shown in the figure, Figure 37 That is, two said eighth bosses 602 of the said sixth support 6 in left front position are in left-right setting, at this time, the said saw blade 14 in left side cannot saw, said ⑤ swings 90 degrees along the clockwise direction, then two said eighth bosses 602 of the said sixth support 6 in left front position will change into front-rear setting, and the swing direction of the said sixth support 6 in left front position is defined as positive direction;

[0099] Suppose initially the said sixth support 6 in right front position is in leisure state, after simplification, as shown in the figure, Figure 38As shown, the two eighth protrusions 602 of the sixth bracket 6 located at the front right are arranged left and right. At this time, the saw blade 14 located on the right cannot cut. When the ⑥ swings 90 degrees counterclockwise, the two eighth protrusions 602 of the sixth bracket 6 located at the front right will change to be arranged front and back. We can define this swing direction of the sixth bracket 6 located at the front right as positive.

[0100] Assuming the sixth support 6, initially located at the left front, is in a working state, simplified as follows: Figure 39 As shown, the two eighth protrusions 602 of the sixth bracket 6 located at the front left are arranged in a front-to-back manner. At this time, the saw blade 14 located on the left can perform sawing. When the fifth step rotates 90 degrees counterclockwise, the two eighth protrusions 602 of the sixth bracket 6 located at the front left will change to a left-to-right arrangement. We can define this rotation direction of the sixth bracket 6 located at the front left as the opposite direction.

[0101] Assuming the sixth support 6, initially located at the front right, is in a working state, simplified as follows: Figure 40 As shown, the two eighth protrusions 602 of the sixth bracket 6 located at the front right are arranged in a front-to-back manner. At this time, the saw blade 14 located on the right can perform sawing. When the ⑥ rotates 90 degrees clockwise, the two eighth protrusions 602 of the sixth bracket 6 located at the front right will change to a left-to-right arrangement. We can define this rotation direction of the sixth bracket 6 located at the front right as the opposite direction.

[0102] The working principle of the device for side-singling single-sided sawing of coupling blank samples provided by this utility model

[0103] like Figure 2 As shown, the left-side view of the device based on this utility model is simplified to... Figure 41 Let's define the outer diameter of the coupling blank sample 20 as V, and the distance from the upper end face of the third body 301 of the third bracket 3 to the lower end face of the ninth body 901 of the ninth bracket 9 as W. Since the two positioning rods 12 at the bottom are inverted and their positions along the vertical direction remain unchanged, while the two positioning rods 12 at the top are upright and their positions along the vertical direction change accordingly with the change of the outer diameter of the coupling blank sample 20, the distance from the upper end face of the coupling blank sample 20 to the lower end face of the ninth body 901 should be equal to the distance from the lower end face of the coupling blank sample 20 to the upper end face of the third body 301. Let's define this distance as U. Since the straight line containing the diameter is the axis of symmetry of the circle, the plane of symmetry of the coupling blank sample 20 along the horizontal direction can always bisect W.

[0104] For ease of description, let's assume that the eight axes of the sixteen second bearing segments 1003 of the four oppositely arranged tenth supports 10 are A, B, C, D, E, F, G and H respectively. By sequentially connecting A, B, C, D, E, F, G and H, a symmetrical octagonal structure ABCDEFGH can be obtained.

[0105] When all four of the tenth supports 10 are erected, the octagonal structure ABCDEFGH can be simplified into a rectangular structure BCFG, as shown below. Figure 43 As shown, at this point, the rectangular structure BCFG has the maximum geometric length along the vertical direction, which is the upper limit that this invention can measure. This corresponds to the theoretical maximum outer diameter of the coupling blank sample 20. Let's set the theoretical maximum outer diameter as V. max Since the present invention adopts a symmetrical structure design, the symmetrical axis of the saw blade 14 along the horizontal direction and the symmetrical axis of the coupling blank sample 20 along the horizontal direction can coincide, that is, the horizontally arranged saw blade 14 can cut along the radial direction of the coupling blank sample 20.

[0106] When all four tenth supports 10 are horizontally arranged, the octagonal structure ABCDEFGH can be simplified into a rectangular structure ADEH, as shown below. Figure 44 As shown, at this point, the rectangular structure ADEH has the minimum geometric length along the vertical direction, which is the lower limit extreme value that this utility model can measure. This corresponds to the theoretical minimum outer diameter of the coupling blank sample 20. Let's set the theoretical minimum outer diameter as V. min Since the present invention adopts a symmetrical structure design, the symmetrical axis of the saw blade 14 along the horizontal direction and the symmetrical axis of the coupling blank sample 20 along the horizontal direction can coincide, that is, the horizontally arranged saw blade 14 can cut along the radial direction of the coupling blank sample 20.

[0107] When all four tenth supports 10 are symmetrically tilted, connecting A and D, connecting E and H, connecting B and G, and connecting C and F, since B and C are located within the two sixth through holes 405 of the inverted fourth support 4, and F and G are located within the two sixth through holes 405 of the upright fourth support 4, and since the linear bearing 11 can only move up and down along the four second bosses 202 of the second support 2, BG and CF are always in the vertical direction; since A and H are located within the two tenth through holes 804 of the left-side eighth support 8, and D and E are located within the two tenth through holes 804 of the right-side eighth support 8, and since this utility model device adopts a symmetrical structure design and a standardized operation mode, AD and EH are always in the horizontal direction;

[0108] In summary, BG is perpendicular to AD, intersecting I, BG is perpendicular to EH, intersecting L, CF is perpendicular to AD, intersecting J, CF is perpendicular to EH, intersecting K, since the ①, the ②, the ③ and the ④ all swing a same angle, that is, ∠ABI = ∠DCJ = ∠EFK = ∠HGL, and ∠BIA = ∠CJD = ∠FKE = ∠GLH = 90 degrees, and combining the internal angle theorem of triangle, it can be deduced that ∠IAB = ∠JDC = ∠KEF = ∠LHG, since AB, CD, EF and GH are distances between two axes of the four second bearing segments 1003 of the tenth support 10, therefore, AB = CD = EF = GH, according to the angle-side-angle judgment theorem of triangle congruence, it can be deduced that the △ABI, the △DCJ, the △EFK and the △HGL are congruent, and further it can be deduced that the corresponding sides are all equal, that is, BI = CJ = FK = GL;

[0109] In order to facilitate the description, the midpoint of AH is set as M, the midpoint of DE is set as N, M and N are connected, and it is not difficult to prove that the plane where MN is located is the symmetry axis plane of AD and EH, since BG is perpendicular to AD and EH, and CF is also perpendicular to AD and EH, therefore, it is not difficult to prove that the quadrilateral structure IJKL is a rectangle, and combining BI = CJ = FK = GL, therefore, it is not difficult to deduce that the plane where MN is located is also the symmetry axis plane of BC and FG, since the utility model adopts a symmetrical structure for design, therefore, the symmetry axis plane of the saw blade 14 along the horizontal direction and the symmetry axis plane of the coupling blank sample 20 along the horizontal direction can coincide, that is, the horizontally arranged saw blade 14 can be sawed along the radial direction of the coupling blank sample 20;

[0110] In summary, no matter whether the four tenth supports 10 are vertically arranged, horizontally arranged or symmetrically inclined arranged, the plane where MN is located is always the symmetry axis plane of the octagonal structure ABCDEFGH along the horizontal direction, that is, the position of the saw blade 14 along the vertical direction can be changed accordingly with the change of the outer diameter of the coupling blank sample 20, but the fact that the symmetry axis plane of the saw blade 14 along the horizontal direction and the symmetry axis plane of the coupling blank sample 20 along the horizontal direction coincide is always unchanged, in this way, the horizontally arranged saw blade 14 can always be sawed along the radial direction of the coupling blank sample 20.

[0113] Step 2: at this time, the four wheels 18 are located at the rightmost end, then the sixth support 6 in front of the left is reversely rotated by 90 degrees so that the two eighth bosses 602 are arranged left and right, then the ①, the ②, the ③ and the ④ are reversely and slowly rotated until the four tenth supports 10 are vertically arranged, then the two upright positioning rods 12 are rotated out downwardly so as to be able to position the coupling blank sample 20, then the second coupling blank sample 20 is horizontally arranged at a predetermined position, then the ①, the ②, the ③ and the ④ are slowly and forwardly rotated until the two upright positioning rods 12 contact the coupling blank sample 20, then the sixth support 6 in front of the right is forwardly rotated by 90 degrees so that the two eighth bosses 602 are arranged front and back, at this time, the saw blade 14 on the right side is opposite to the coupling blank sample 20, then the two upright positioning rods 12 are rotated in upwardly so as not to affect the operation of the utility model device, then the rotating shaft 15 on the right side is uniformly and slowly rotated, then the second support vehicle is uniformly and slowly moved to the left, at this time, the saw blade 14 on the right side starts to work until the side end surface of the coupling blank sample 20 is completely sawn on one side, so that the second coupling blank sample 20 is sawn on one side.

[0114] The device for sawing the coupling blank sample in lateral single surface provided by the utility model adopts symmetrical structure for design, firstly, a plurality of specifications of the device should be designed and manufactured according to the outer diameter specification, wall thickness specification, setting height and fixed length of the coupling blank sample; the predetermined position refers to the coupling blank sample should be set in the middle position of the device, namely the upper end surface of the coupling blank sample should be consistent with the lower end surface height of the two positioning rods in normal position, the lower end surface of the coupling blank sample should be consistent with the upper end surface height of the two positioning rods in inverted position, which can guarantee that the horizontal symmetry axis surface of the coupling blank sample and the horizontal symmetry axis surface of the saw blade can be coincided, and then the saw blade can be sawed along the radial direction of the coupling blank sample, and the saw blade can saw the whole wall thickness of the side end surface of the coupling blank sample; during the whole sawing process, the horizontal moving speed of the second support vehicle and the actual speed of the saw blade sawing the coupling blank sample should be consistent with each other, so as to realize the stable operation of the device.
