Description

Technical Field

[0001] The present invention belongs to the technical field of industrial equipment, and in particular relates to a size adjustment method and a size adjustment device. Background Art

[0002] In the prior art, angle adjustment is usually achieved through structures such as threads, scissor mechanisms or ratchets, which have poor accuracy. Distance adjustment is usually achieved through threads or hydraulic jacks, etc. The above-mentioned adjustment devices have low accuracy and are difficult to achieve quantitative adjustment and graded adjustment. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0004] To this end, a first aspect of the present invention aims to provide a size adjustment method.

[0005] A second aspect of the present invention is to provide a size adjustment device.

[0006] To achieve at least one of the above-mentioned purposes, the first aspect of the present invention proposes a size adjustment method, which is applicable to a size adjustment device, the size adjustment device comprising a first turntable and a second turntable coaxially connected to the first turntable, the second turntable being capable of rotating relative to the first turntable, the first turntable having a plurality of first through holes evenly distributed along the circumference, and the second turntable having a plurality of second through holes evenly distributed along the circumference, the size adjustment method comprising: adjusting the second turntable to a starting position, and when the second turntable is at the starting position, aligning a preset number of first through holes with a preset number of second through holes; rotating the second turntable until the preset number of first through holes and the preset number of second through holes are aligned at least once; determining the number of times the preset number of first through holes and the preset number of second through holes are aligned during the rotation of the second turntable as the first number; and determining the angle rotated by the second turntable based on the number of the first through holes, the number of the second through holes, the preset number and the first number.

[0007] The size adjustment method proposed in this application is applicable to a size adjustment device that enables angle adjustment. The size adjustment device includes a first rotating disk and a second rotating disk, the first rotating disk and the second rotating disk being coaxially connected and rotatable relative to the first rotating disk. While the second rotating disk rotates, the first rotating disk remains stationary. The first rotating disk is provided with a plurality of first through-holes evenly distributed along the circumference, and the second rotating disk is provided with a plurality of second through-holes evenly distributed along the circumference. Starting from a starting position, when the second rotating disk rotates at least one preset unit angle relative to the first rotating disk, a preset number of the first through-holes align with a preset number of the second through-holes. Specifically, the starting position is the position where a preset number of the first through-holes align with a preset number of the second through-holes. That is, when a preset number of the first through-holes are already aligned with a preset number of the second through-holes, after the second rotating disk rotates at one or more preset unit angles, a preset number of the first through-holes still align with a preset number of the second through-holes. Thus, the angle of rotation of the second rotating disk can be determined by the alignment of the first through-holes with the second through-holes.

[0008] Furthermore, the size adjustment method specifically includes the following steps: first, adjusting the second turntable to a starting position, wherein a preset number of first through-holes are aligned with the preset number of second through-holes when the second turntable is in the starting position. Then, rotating the second turntable until the preset number of first through-holes and the preset number of second through-holes are aligned at least once. It is understood that during the rotation of the second turntable relative to the first turntable, each time the second turntable rotates through a preset unit angle, the preset number of first through-holes and the preset number of second through-holes will align. Therefore, the angle of rotation of the second turntable can be determined based on the number of times the preset number of first through-holes and the preset number of second through-holes are aligned. Subsequently, to determine the angle of rotation of the second turntable, it is necessary to determine the number of times the preset number of first through-holes and the preset number of second through-holes are aligned during the rotation of the second turntable, and use this as a first number. Subsequently, the angle of rotation of the second turntable is determined based on the number of first through-holes, the number of second through-holes, the preset number, and the first number. Specifically, the size of the preset unit angle is related to the number of first and second through-holes. As can be understood, based on the principle of a vernier caliper, the greatest common divisor of the numbers of first and second through-holes can be determined. The quotient of this greatest common divisor and the product of the numbers of first and second through-holes, multiplied by 360, is the preset unit angle. Furthermore, the angle rotated by the second turntable can be determined based on the product of the preset unit angle and the first divisor. This allows for quantitative and multi-level angle adjustment.

[0009] By providing a plurality of first through-holes on a first turntable and a plurality of second through-holes on a second turntable coaxial with the first turntable, the angle of rotation of the second turntable can be determined based on the alignment of the first and second through-holes. This size adjustment method determines the angle of rotation of the second turntable based on the number of first through-holes, the number of second through-holes, the number of aligned first and second through-holes, and the number of times the first and second through-holes align during the rotation of the second turntable, thereby achieving quantitative and multi-level angle adjustment. This size adjustment method is easy to operate and highly accurate.

[0010] The size adjustment method according to the present invention may also have the following distinguishing technical features:

[0011] In the above technical solution, further, the number of first through holes is A, the number of multiple second through holes is B, the preset number is N, N is the greatest common divisor of A and B, the first divisor is P, and the angle rotated by the second turntable is N / (A×B)×360°×P.

[0012] In this technical solution, a formula defines the angle through which the second turntable rotates. Specifically, the number of first through holes is A, the number of the plurality of second through holes is B, the preset number is N, N is the greatest common divisor of A and B, the first divisor is P, and the angle through which the second turntable rotates is N / (A×B)×360°×P.

[0013] In one possible technical solution, A is 20, B is 18, the greatest common divisor N of A and B is 2, and the preset unit angle is 2 / (18 × 20) × 360° = 2°. This means that, starting from the starting position, every 2° the second turntable rotates, two first through-holes align with two second through-holes. Furthermore, the product of the preset unit angle and the first divisor P is the angle the second turntable has rotated. Thus, the angle the second turntable has rotated can be determined by the alignment of the first and second through-holes.

[0014] Furthermore, the value of the preset unit angle is related to the number of the first through hole and the second through hole. The user can set different numbers of through holes on the first turntable and the second turntable according to actual needs to change the preset unit angle, thereby determining the positioning accuracy that meets actual needs.

[0015] In the above technical solution, the size adjustment device further includes a winding sleeve connected to the second turntable, the winding sleeve is used to wind the rope, and the rope can be gradually separated from the winding sleeve as the winding sleeve rotates. The size adjustment method also includes: determining the length of the rope separated from the winding sleeve based on the angle rotated by the second turntable and the diameter of the winding sleeve.

[0016] In this technical solution, the length can also be adjusted by a size adjustment device. Specifically, a winding sleeve is also provided in the positioning device, and the winding sleeve is connected to the second turntable, and the winding sleeve is used to wind the rope. When the second turntable drives the winding sleeve to rotate, the rope on the winding sleeve can gradually separate from the winding sleeve. Furthermore, the size adjustment method also includes determining the length of the rope separated from the winding sleeve based on the angle rotated by the second turntable and the diameter of the winding sleeve. It can be understood that when the second turntable drives the winding sleeve to rotate through one or more preset unit angles, the length of the rope separated from the winding sleeve changes accordingly. When the diameter of the winding sleeve and the angle rotated by the second turntable are determined, the length of the rope separated from the winding sleeve can be determined. In this way, the length can be adjusted by the size adjustment device.

[0017] In the above technical solution, further, the diameter of the winding sleeve is D, and the length of the wire rope separated from the winding sleeve is N / (A×B)×P×π×D.

[0018] This technical solution defines a formula for length adjustment. Specifically, the number of first through holes is A, the number of the plurality of second through holes is B, the preset number is N, N is the greatest common divisor of A and B, the first divisor is P, the diameter of the winding sleeve is D, and the length of the cord separated from the winding sleeve is N / (A×B)×P×π×D. The length adjustment is performed based on the length of the cord separated from the winding sleeve during the rotation of the second turntable.

[0019] In one possible technical solution, A is 20, B is 18, the greatest common divisor N of A and B is 2, and the preset unit angle is 2 / (18×20)×360°=2°. That is, starting from the starting position, every 2° of rotation of the second turntable aligns two first through-holes with two second through-holes. The diameter of the winding sleeve is 600 mm, and the first divisor is 3. During the rotation of the second turntable, the length of the rope separated from the winding sleeve is 2 / (18×20)×3×π×600=31.398 mm.

[0020] In the above technical solution, further, the size adjustment device also includes multiple positioning columns, any positioning column can be inserted into the first through hole and the second through hole that are aligned with each other, and before adjusting the second turntable to the starting position, it also includes: moving the multiple positioning columns out of the first through hole and the second through hole.

[0021] In this technical solution, the size adjustment device is further provided with a plurality of positioning posts, which can be inserted into the first and second through-holes to position the first and second turntables. When the positioning posts are inserted into the first and second through-holes, the second turntable cannot rotate. Therefore, before adjusting the second turntable to its starting position, the plurality of positioning posts must be removed from the first and second through-holes to enable smooth rotation of the second turntable.

[0022] In the above technical solution, further, after rotating the second turntable until a preset number of first through holes and a preset number of second through holes are aligned at least once, it also includes: inserting a plurality of positioning posts into the aligned first through holes and second through holes.

[0023] In this technical solution, after the second turntable is rotated until a preset number of first through holes and a preset number of second through holes are aligned at least once, a plurality of positioning posts are inserted into the mutually aligned first through holes and second through holes. It is understandable that when the second turntable is rotated by one or more preset unit angles relative to the first turntable, the N first through holes are aligned with the N second through holes. At this time, the first turntable and the second turntable need to be fixed to determine the angle currently rotated by the second turntable. In order to relatively fix the first turntable and the second turntable, a plurality of positioning posts are inserted into the mutually aligned first through holes and the second through holes. In this way, the first turntable and the second turntable can be relatively fixed, so that the second turntable remains in its current position and relative rotation between the second turntable and the first turntable is prevented.

[0024] In the above technical solution, further, the size adjustment device also includes a plurality of locking parts adapted to the positioning columns. After the plurality of positioning columns are inserted into the first through holes and the second through holes aligned with each other, it also includes: connecting the plurality of locking parts to the corresponding plurality of positioning columns to lock the positioning columns.

[0025] In this technical solution, the positioning device is further provided with a plurality of locking members, which are arranged correspondingly to the plurality of positioning posts. Understandably, if the positioning posts are not locked after being inserted into the mutually aligned first and second through holes, they can easily become loose, thereby causing relative rotation between the second turntable and the first turntable, resulting in inaccurate angle adjustment. To avoid the above-mentioned problem, after the operator inserts the positioning posts into the mutually aligned first and second through holes, it is necessary to connect the plurality of locking members to the corresponding plurality of positioning posts to lock the positioning posts. When the locking members are connected to the positioning posts, the positioning posts cannot be dislodged from the first and second through holes.

[0026] In a possible technical solution, the positioning column is a bolt and the locking member is a nut.

[0027] In the above technical solution, further, the circumferential diameter of the plurality of first through holes is the same as the circumferential diameter of the plurality of second through holes.

[0028] In this technical solution, the relationship between the circumference of the first through-holes and the circumference of the second through-holes is defined. Specifically, the diameter of the circumference of the plurality of first through-holes is the same as the diameter of the circumference of the plurality of second through-holes. Understandably, if the first and second turntables are coaxial, by setting the diameter of the circumference of the plurality of first through-holes to be the same as the diameter of the circumference of the plurality of second through-holes, some of the first through-holes can be aligned with the second through-holes, thus avoiding misalignment between the first and second through-holes.

[0029] In the above technical solution, further, the diameter of the first through hole is the same as the diameter of the second through hole.

[0030] In this technical solution, the diameter size of the first through hole and the second through hole is limited. Specifically, the diameter of the first through hole is the same as the diameter of the second through hole. It can be understood that after the second turntable rotates at least one preset unit angle relative to the first turntable, the N first through holes are aligned with the N second through holes. At this time, it is necessary to position the aligned first through holes and second through holes. By setting the diameter size of the first through hole and the second through hole to be the same, the aligned first through holes and second through holes can be better positioned to avoid a gap between the first through hole or the second through hole and the positioning column used for positioning, which causes the second turntable to move in a tangled manner.

[0031] In the above technical solution, further, when the positioning post is inserted into the first through hole and the second through hole, the positioning post fits with the hole walls of the first through hole and the second through hole.

[0032] In this technical solution, when the positioning post is inserted into the first through hole and the second through hole, the positioning post fits in with the hole walls of the first through hole and the second through hole. It can be understood that the positioning post is used to limit the second turntable. The positioning post cooperates with the first through hole and the second through hole to prevent the second turntable from rotating relative to the first turntable, so as to ensure the accuracy of size adjustment. If there is a large gap between the positioning post and the first through hole or the second through hole, then it is obvious that the second turntable can rotate within a certain range relative to the first turntable, which will reduce the accuracy of size adjustment. In order to avoid this problem, the present application enables the positioning post to fit in with the hole walls of the first through hole and the second through hole, thereby preventing the second turntable from rotating relative to the first turntable, thereby improving the accuracy of size adjustment.

[0033] The second aspect of the present invention also proposes a size adjustment device, comprising: a first turntable, the first turntable is provided with a plurality of first through holes uniformly distributed along the circumferential direction, and the number of the plurality of first through holes is A; a second turntable, coaxially connected to the first turntable, the second turntable can rotate relative to the first turntable, the second turntable is provided with a plurality of second through holes uniformly distributed along the circumferential direction, and the number of the second through holes is B; starting from a starting position, when the second turntable rotates at least one preset unit angle relative to the first turntable, N first through holes are aligned with N second through holes, and the starting position is the position where N first through holes are aligned with N second through holes; the preset unit angle is N / (A×B)×360°, and N is the greatest common divisor of A and B.

[0034] The positioning device proposed in this application is used to locate an angle. The positioning principle of the positioning device is similar to that of a vernier caliper. The angle of relative rotation of the two turntables is determined by the alignment of the through-holes on the two turntables that can rotate relative to each other. The positioning device includes a first turntable and a second turntable. The first turntable is coaxially connected to the second turntable, and the second turntable can rotate relative to the first turntable. When the second turntable rotates, the first turntable can remain fixed. The first turntable is provided with a plurality of first through-holes evenly distributed along the circumference, the number of first through-holes being A. The second turntable is provided with a plurality of second through-holes evenly distributed along the circumference, the number of second through-holes being B, wherein A and B have a greatest common divisor N. Starting from a starting position, when the second turntable rotates at least one preset unit angle relative to the first turntable, the N first through-holes are aligned with the N second through-holes. Specifically, the starting position is the position where the N first through-holes are aligned with the N second through-holes. That is, when N first through-holes are already aligned with N second through-holes, after the second turntable rotates through one or more preset unit angles, N first through-holes are still aligned with N second through-holes. Thus, the angle of rotation of the second turntable can be determined based on the alignment of the first through-holes with the second through-holes. Specifically, the preset unit angle is N / (A×B)×360°.

[0035] In a possible technical solution, A is 20, B is 18, the greatest common divisor N of A and B is 2, and the preset unit angle is 2 / (18×20)×360°=2°. That is, starting from the starting position, every time the second turntable rotates 2°, two first through holes and two second through holes are aligned. In this way, the angle rotated by the second turntable can be determined by the state of alignment between the first through holes and the second through holes.

[0036] In another possible technical solution, the second turntable may be kept stationary, and the first turntable may be rotated relative to the second turntable.

[0037] Furthermore, the value of the preset unit angle is related to the number of the first through hole and the second through hole. The operator can set different numbers of through holes on the first turntable and the second turntable according to actual needs to change the preset unit angle, thereby determining the positioning accuracy that meets actual needs.

[0038] By providing a plurality of first through-holes on a first turntable and a plurality of second through-holes on a second turntable coaxial with the first turntable, the angle of rotation of the second turntable can be determined based on the alignment of the first and second through-holes. This size adjustment device determines the angle of rotation of the second turntable based on the number of first through-holes, the number of second through-holes, the number of aligned first and second through-holes, and the number of times the first and second through-holes align during the second turntable's rotation, thereby achieving quantitative and multi-level angle adjustment. This size adjustment method is easy to operate and highly accurate.

[0054] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0055] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0056] Refer to the following Figures 1 to 11 The size adjustment method and the size adjustment device 100 provided according to some embodiments of the present invention are described.

[0057] Example 1:

[0058] like Figure 1 、 Figure 2 、 Figure 5 and Figure 6 As shown, the present invention proposes a size adjustment method, which is applicable to a size adjustment device 100. The size adjustment device 100 includes a first turntable 110 and a second turntable 120 coaxially connected to the first turntable 110. The second turntable 120 can rotate relative to the first turntable 110. The first turntable 110 has a plurality of first through holes 111 evenly distributed along the circumference, and the second turntable 120 has a plurality of second through holes 121 evenly distributed along the circumference.

[0059] Furthermore, angle adjustment can be achieved through the size adjustment device 100. The size adjustment device 100 includes a first turntable 110 and a second turntable 120, wherein the first turntable 110 and the second turntable 120 are coaxially connected, and the second turntable 120 can rotate relative to the first turntable 110, and when the second turntable 120 rotates, the first turntable 110 can remain fixed. The first turntable 110 is provided with a plurality of first through holes 111 uniformly distributed along the circumference, and the second turntable 120 is provided with a plurality of second through holes 121 uniformly distributed along the circumference. Starting from the starting position, when the second turntable 120 rotates at least one preset unit angle relative to the first turntable 110, the preset number of first through holes 111 is aligned with the preset number of second through holes 121. Specifically, the starting position is the position where the preset number of first through holes 111 is aligned with the preset number of second through holes 121. That is, when a preset number of first through holes 111 are aligned with a preset number of second through holes 121, after the second turntable 120 rotates through one or more preset unit angles, a preset number of first through holes 111 are still aligned with a preset number of second through holes 121. In this way, the angle rotated by the second turntable 120 can be determined by the state of alignment between the first through holes 111 and the second through holes 121.

[0060] Example 2:

[0061] like Figure 7 As shown in FIG, a flow chart of a size adjustment method according to an embodiment of the present invention is shown. The size adjustment method includes the following steps S102 to S108:

[0062] S102: adjusting the second turntable to a starting position, wherein when the second turntable is at the starting position, a preset number of first through holes are aligned with a preset number of second through holes;

[0063] S104: rotating the second rotating disk until a preset number of first through holes and a preset number of second through holes are aligned at least once;

[0064] S106: Determine that the number of times a preset number of first through holes is aligned with a preset number of second through holes during the rotation of the second turntable is a first number;

[0065] S108: Determine the angle rotated by the second turntable according to the number of the first through holes, the number of the second through holes, the preset number, and the first number.

[0066] Furthermore, the size adjustment method specifically includes the following steps: first, adjusting the second turntable to a starting position, wherein a preset number of first through-holes are aligned with the preset number of second through-holes when the second turntable is in the starting position. Then, rotating the second turntable until the preset number of first through-holes and the preset number of second through-holes are aligned at least once. It is understood that during the rotation of the second turntable relative to the first turntable, each time the second turntable rotates through a preset unit angle, the preset number of first through-holes and the preset number of second through-holes will align. Therefore, the angle of rotation of the second turntable can be determined based on the number of times the preset number of first through-holes and the preset number of second through-holes are aligned. Subsequently, to determine the angle of rotation of the second turntable, it is necessary to determine the number of times the preset number of first through-holes and the preset number of second through-holes are aligned during the rotation of the second turntable, and use this as a first number. Subsequently, the angle of rotation of the second turntable is determined based on the number of first through-holes, the number of second through-holes, the preset number, and the first number. Specifically, the size of the preset unit angle is related to the number of first and second through-holes. As can be understood, based on the principle of a vernier caliper, the greatest common divisor of the numbers of first and second through-holes can be determined. The quotient of this greatest common divisor and the product of the numbers of first and second through-holes, multiplied by 360, is the preset unit angle. Furthermore, the angle rotated by the second turntable can be determined based on the product of the preset unit angle and the first divisor. This allows for quantitative and multi-level angle adjustment.

[0067] By providing a plurality of first through-holes on a first turntable and a plurality of second through-holes on a second turntable coaxial with the first turntable, the angle of rotation of the second turntable can be determined based on the alignment of the first and second through-holes. This size adjustment method determines the angle of rotation of the second turntable based on the number of first through-holes, the number of second through-holes, the number of aligned first and second through-holes, and the number of times the first and second through-holes align during the rotation of the second turntable, thereby achieving quantitative and multi-level angle adjustment. This size adjustment method is easy to operate and highly accurate.

[0068] Example 3:

[0069] In a specific embodiment based on Example 2, the number of first through holes is A, the number of multiple second through holes is B, the preset number is N, N is the greatest common divisor of A and B, the first divisor is P, and the angle rotated by the second turntable is N / (A×B)×360°×P.

[0070] In this embodiment, a formula is defined for the angle through which the second turntable rotates. Specifically, the number of the first through holes is A, the number of the plurality of second through holes is B, the preset number is N, N is the greatest common divisor of A and B, the first divisor is P, and the angle through which the second turntable rotates is N / (A×B)×360°×P.

[0071] In one possible embodiment, A is 20, B is 18, the greatest common divisor N of A and B is 2, and the preset unit angle is 2 / (18 × 20) × 360° = 2°. That is, starting from the starting position, every 2° the second turntable rotates, two first through-holes align with two second through-holes. Furthermore, the product of the preset unit angle and the first divisor P is the angle the second turntable has rotated. Thus, the angle the second turntable has rotated can be determined by the alignment of the first through-holes with the second through-holes.

[0072] Furthermore, the value of the preset unit angle is related to the number of the first through hole and the second through hole. The user can set different numbers of through holes on the first turntable and the second turntable according to actual needs to change the preset unit angle, thereby determining the positioning accuracy that meets actual needs.

[0073] Example 4:

[0074] like Figure 1 and Figure 3 As shown, in a specific embodiment based on any of the above embodiments, the size adjustment device 100 further includes a plurality of positioning posts 130, each of which can be inserted into the first through hole 111 and the second through hole 121 that are aligned with each other. The positioning posts 130 are used to position the second rotating disk 120 to prevent the second rotating disk 120 from rotating relative to the first rotating disk 110.

[0075] Embodiment 5:

[0076] Figure 8 The second flow chart of the size adjustment method according to an embodiment of the present invention is shown. The size adjustment method includes the following steps S202 to S210:

[0077] S202: moving the plurality of positioning posts out of the first through hole and the second through hole;

[0078] S204: adjusting the second turntable to a starting position, wherein when the second turntable is at the starting position, a preset number of first through holes are aligned with a preset number of second through holes;

[0079] S206: rotating the second rotating disk until a preset number of first through holes and a preset number of second through holes are aligned at least once;

[0080] S208: Determine that the number of times a preset number of first through holes is aligned with a preset number of second through holes during the rotation of the second turntable is a first number;

[0081] S210: Determine an angle rotated by the second turntable according to the number of the first through holes, the number of the second through holes, the preset number, and the first number.

[0082] In this embodiment, the size adjustment device is further provided with a plurality of positioning posts, which can be inserted into the first and second through-holes to position the first and second rotating disks. When the positioning posts are inserted into the first and second through-holes, the second rotating disk cannot rotate. Therefore, before adjusting the second rotating disk to its starting position, the plurality of positioning posts must be removed from the first and second through-holes to enable smooth rotation of the second rotating disk.

[0083] Example 6:

[0084] Figure 9 The third flow chart of the size adjustment method according to an embodiment of the present invention is shown. The size adjustment method includes the following steps S302 to S312:

[0085] S302: moving the plurality of positioning posts out of the first through hole and the second through hole;

[0086] S304: adjusting the second turntable to a starting position, wherein when the second turntable is at the starting position, a preset number of first through holes are aligned with a preset number of second through holes;

[0087] S306: Rotate the second rotating disk until a preset number of first through holes and a preset number of second through holes are aligned at least once;

[0088] S308: inserting a plurality of positioning posts into the first through hole and the second through hole aligned with each other;

[0089] S310: Determine that the number of times a preset number of first through holes is aligned with a preset number of second through holes during the rotation of the second turntable is a first number;

[0090] S312: Determine the angle rotated by the second turntable according to the number of the first through holes, the number of the second through holes, the preset number, and the first number.

[0091] In this embodiment, after the second turntable is rotated until a preset number of first through holes and a preset number of second through holes are aligned at least once, a plurality of positioning posts are inserted into the mutually aligned first through holes and second through holes. It is understandable that when the second turntable is rotated by one or more preset unit angles relative to the first turntable, the N first through holes are aligned with the N second through holes. At this time, the first turntable and the second turntable need to be fixed to determine the angle currently rotated by the second turntable. In order to relatively fix the first turntable and the second turntable, a plurality of positioning posts are inserted into the mutually aligned first through holes and the second through holes. In this way, the first turntable and the second turntable can be relatively fixed, so that the second turntable remains in its current position and relative rotation between the second turntable and the first turntable is prevented.

[0092] Embodiment seven:

[0093] like Figure 1 and Figure 3 As shown, in a specific embodiment based on any of the above embodiments, the size adjustment device 100 also includes a plurality of locking members 140 adapted to the positioning posts 130, and the locking members 140 are used to lock the positioning posts 130 to prevent the positioning posts 130 from falling out of the first through holes 111 and the second through holes 121, thereby enabling the positioning posts 130 to remain in the first through holes 111 and the second through holes 121 to limit the second turntable 120.

[0094] Embodiment 8:

[0095] Figure 10 FIG4 is a flow chart of a size adjustment method according to an embodiment of the present invention. The size adjustment method includes the following steps S402 to S414:

[0096] S402: moving the plurality of positioning posts out of the first through hole and the second through hole;

[0097] S404: adjusting the second turntable to a starting position, wherein when the second turntable is at the starting position, a preset number of first through holes are aligned with a preset number of second through holes;

[0098] S406: Rotate the second rotating disk until a preset number of first through holes and a preset number of second through holes are aligned at least once;

[0099] S408: inserting a plurality of positioning posts into the first through hole and the second through hole aligned with each other;

[0100] S410: Connecting a plurality of locking members to a corresponding plurality of positioning posts to lock the positioning posts;

[0101] S412: Determine that the number of times a preset number of first through holes is aligned with a preset number of second through holes during the rotation of the second turntable is a first number;

[0102] S414: Determine the angle rotated by the second turntable according to the number of the first through holes, the number of the second through holes, the preset number, and the first number.

[0103] In this embodiment, the positioning device is further provided with multiple locking members, which are arranged correspondingly to the multiple positioning posts. Understandably, if the positioning posts are not locked after being inserted into the mutually aligned first and second through-holes, they can easily become loose, causing relative rotation between the second turntable and the first turntable, resulting in inaccurate angle adjustment. To avoid this problem, after inserting the positioning posts into the mutually aligned first and second through-holes, the operator needs to connect the multiple locking members to the corresponding multiple positioning posts to lock the positioning posts. When the locking members are connected to the positioning posts, the positioning posts cannot be removed from the first and second through-holes.

[0104] In a possible embodiment, the positioning column is a bolt, and the locking member is a nut.

[0105] Embodiment 9:

[0106] like Figure 3 and Figure 4 As shown, in a specific embodiment based on any of the above embodiments, the size adjustment device 100 further includes a winding sleeve 160 connected to the second turntable 120, and the winding sleeve 160 is used to wind the rope, and the rope can be gradually separated from the winding sleeve as the winding sleeve 160 rotates.

[0107] Embodiment 10:

[0108] Figure 11 FIG5 is a flowchart of a size adjustment method according to an embodiment of the present invention. The size adjustment method includes the following steps S502 to S516:

[0109] S502: moving the plurality of positioning posts out of the first through hole and the second through hole;

[0110] S504: adjusting the second turntable to a starting position, wherein when the second turntable is at the starting position, a preset number of first through holes are aligned with a preset number of second through holes;

[0111] S506: Rotate the second rotating disk until a preset number of first through holes and a preset number of second through holes are aligned at least once;

[0112] S508: inserting a plurality of positioning posts into the first through hole and the second through hole aligned with each other;

[0113] S510: Connecting a plurality of locking members to a corresponding plurality of positioning posts to lock the positioning posts;

[0114] S512: Determine that the number of times a preset number of first through holes is aligned with a preset number of second through holes during the rotation of the second turntable is a first number;

[0115] S514: Determine the angle rotated by the second turntable according to the number of the first through holes, the number of the second through holes, the preset number, and the first number;

[0116] S516: Determine the length of the wire rope separated from the winding sleeve according to the angle rotated by the second rotating disk and the diameter of the winding sleeve.

[0117] In this embodiment, the length can also be adjusted by a size adjustment device. Specifically, a winding sleeve is also provided in the positioning device, and the winding sleeve is connected to the second turntable, and the winding sleeve is used to wind the rope. When the second turntable drives the winding sleeve to rotate, the rope on the winding sleeve can gradually separate from the winding sleeve. Furthermore, the size adjustment method also includes determining the length of the rope separated from the winding sleeve based on the angle rotated by the second turntable and the diameter of the winding sleeve. It can be understood that when the second turntable drives the winding sleeve to rotate through one or more preset unit angles, the length of the rope separated from the winding sleeve changes accordingly. When the diameter of the winding sleeve and the angle rotated by the second turntable are determined, the length of the rope separated from the winding sleeve can be determined. In this way, the length can be adjusted by the size adjustment device.

[0118] Example 11:

[0119] In a specific embodiment based on the tenth embodiment, the diameter of the winding sleeve is D, and the length of the wire rope separated from the winding sleeve is N / (A×B)×P×π×D.

[0120] In this embodiment, a formula for length adjustment is defined. Specifically, the number of first through holes is A, the number of the plurality of second through holes is B, the preset number is N, N is the greatest common divisor of A and B, the first divisor is P, the diameter of the winding sleeve is D, and the length of the wire rope separated from the winding sleeve is N / (A×B)×P×π×D. The length adjustment is performed based on the length of the wire rope separated from the winding sleeve during the rotation of the second turntable.

[0121] In one possible embodiment, A is 20, B is 18, the greatest common divisor N of A and B is 2, and the preset unit angle is 2 / (18×20)×360°=2°. That is, starting from the starting position, every 2° of rotation of the second turntable aligns two first through-holes with two second through-holes. The diameter of the winding sleeve is 600 mm, and the first divisor is 3. During the rotation of the second turntable, the length of the wire rope separated from the winding sleeve is 2 / (18×20)×3×π×600=31.398 mm.

[0122] Example 12:

[0123] like Figure 2 、 Figure 4 and Figure 5 As shown, in a specific embodiment based on any of the above embodiments, the diameter of the circle where the multiple first through holes 111 are located is the same as the diameter of the circle where the multiple second through holes 121 are located.

[0124] In this embodiment, the relationship between the circumference of the first through holes 111 and the circumference of the second through holes 121 is defined. Specifically, the diameter of the circumference of the plurality of first through holes 111 is the same as the diameter of the circumference of the plurality of second through holes 121. Understandably, when the first turntable 110 and the second turntable 120 are coaxial, by setting the diameter of the circumference of the plurality of first through holes 111 to be the same as the diameter of the circumference of the plurality of second through holes 121, some of the first through holes 111 can be aligned with the second through holes 121, thereby avoiding misalignment between the first through holes 111 and the second through holes 121.

[0125] Furthermore, the diameter of the first through hole 111 is the same as the diameter of the second through hole 121 .

[0126] In this embodiment, the diameter size of the first through hole 111 and the second through hole 121 is limited. Specifically, the diameter of the first through hole 111 is the same as the diameter of the second through hole 121. It can be understood that after the second turntable 120 rotates at least one preset unit angle relative to the first turntable 110, the N first through holes 111 are aligned with the N second through holes 121. At this time, it is necessary to position the aligned first through holes 111 and the second through holes 121. By setting the diameter size of the first through hole 111 and the second through hole 121 to be the same, the aligned first through holes 111 and the second through holes 121 can be better positioned to avoid a gap between the first through hole 111 or the second through hole 121 and the positioning column 130 used for positioning, which causes the second turntable 120 to move in series.

[0127] Furthermore, when the positioning post 130 is inserted into the first through hole 111 and the second through hole 121 , the positioning post 130 fits in contact with the hole walls of the first through hole 111 and the second through hole 121 .

[0128] In this embodiment, when the positioning post 130 is inserted into the first through-hole 111 and the second through-hole 121, the positioning post 130 abuts against the walls of the first through-hole 111 and the second through-hole 121. It can be understood that the positioning post 130 is used to limit the position of the second turntable 120. By cooperating with the first through-hole 111 and the second through-hole 121, the positioning post 130 prevents the second turntable 130 from rotating relative to the first turntable 110, thereby ensuring accurate sizing. If there is a large gap between the positioning post 130 and the first through-hole 111 or the second through-hole 121, the second turntable 120 can obviously rotate within a certain range relative to the first turntable 110, which will obviously reduce the accuracy of sizing. To avoid this problem, the present application enables the positioning post 130 to abut against the walls of the first through-hole 111 and the second through-hole 121, thereby preventing relative rotation between the second turntable 120 and the first turntable 110 and improving the accuracy of sizing.

[0129] Example 13

[0130] like Figure 1 、 Figure 2 and Figure 5 As shown, the second aspect of the present invention further proposes a size adjustment device 100, including: a first turntable 110, the first turntable 110 is provided with a plurality of first through holes 111 uniformly distributed along the circumferential direction, and the number of the plurality of first through holes 111 is A; a second turntable 120, coaxially connected to the first turntable 110, the second turntable 120 can rotate relative to the first turntable 110, the second turntable 120 is provided with a plurality of second through holes 121 uniformly distributed along the circumferential direction, and the number of the second through holes 121 is B; starting from the starting position, when the second turntable 120 rotates at least one preset unit angle relative to the first turntable 110, the N first through holes 111 are aligned with the N second through holes 121, and the starting position is the position where the N first through holes 111 are aligned with the N second through holes 121; the preset unit angle is N / (A×B)×360°, and N is the greatest common divisor of A and B.

[0131] The positioning device proposed in this application is used to locate an angle. The positioning principle of the positioning device is similar to that of a vernier caliper. The angle of relative rotation of the two turntables is determined by the alignment of the through holes on the two turntables that can rotate relative to each other. The positioning device includes a first turntable 110 and a second turntable 120. The first turntable 110 is coaxially connected to the second turntable 120, and the second turntable 120 can rotate relative to the first turntable 110. When the second turntable 120 rotates, the first turntable 110 can remain fixed. The first turntable 110 is provided with a plurality of first through holes 111 uniformly distributed along the circumference, and the number of the first through holes 111 is A. The second turntable 120 is provided with a plurality of second through holes 121 uniformly distributed along the circumference, and the number of the second through holes 121 is B, wherein there is a greatest common divisor N between A and B. Starting from the starting position, when the second rotating disk 120 rotates at least one preset unit angle relative to the first rotating disk 110, the N first through-holes 111 are aligned with the N second through-holes 121. Specifically, the starting position is the position where the N first through-holes 111 are aligned with the N second through-holes 121. That is, when the N first through-holes 111 are already aligned with the N second through-holes 121, after the second rotating disk 120 rotates one or more preset unit angles, N first through-holes 111 are still aligned with the N second through-holes 121. In this way, the angle rotated by the second rotating disk 120 can be determined by the state of alignment between the first through-holes 111 and the second through-holes 121. Specifically, the preset unit angle is N / (A×B)×360°.

[0132] In a possible embodiment, A is 20, B is 18, the greatest common divisor N of A and B is 2, and the preset unit angle is 2 / (18×20)×360°=2°. That is, starting from the starting position, every time the second turntable 120 rotates 2°, two first through holes 111 and two second through holes 121 are aligned. In this way, the angle rotated by the second turntable 120 can be determined by the state of alignment between the first through holes 111 and the second through holes 121.

[0133] In another possible embodiment, the second turntable 120 may be kept stationary, and the first turntable 110 may be rotated relative to the second turntable 120 .

[0134] Furthermore, the value of the preset unit angle is related to the number of the first through hole 111 and the second through hole 121. The operator can set different numbers of through holes on the first turntable 110 and the second turntable 120 according to actual needs to change the preset unit angle, thereby determining the positioning accuracy that meets the actual needs.

[0135] By providing a plurality of first through-holes 111 on the first turntable 110 and a plurality of second through-holes 121 on the second turntable 120 coaxial with the first turntable 110, the angle of rotation of the second turntable 120 can be determined based on the alignment of the first through-holes 111 with the second through-holes 121. The size adjustment device 100 determines the angle of rotation of the second turntable 120 based on the number of first through-holes 111, the number of second through-holes 121, the number of aligned first and second through-holes 111, 121, and the number of times the first and second through-holes 111, 121 align during rotation of the second turntable 120, thereby achieving quantitative and multi-level angle adjustment. This size adjustment method is easy to operate and highly accurate.
