[Figure 3] This is a schematic diagram of a positioning assembly according to an embodiment of the present invention. [Figure 4] This is a plan view of Figure 1.

[Figure 6] This figure shows the usage state in which multiple insertion columns according to an embodiment of the present invention are inserted into multiple first positioning holes. [Figure 7] This figure shows the usage state in which multiple insertion columns according to an embodiment of the present invention are inserted into multiple second positioning holes. [Modes for carrying out the invention] 【0008】 Possible embodiments of the present invention will be described below using only examples, but this does not limit the scope of protection sought by the present invention. The terms "one" or "at least one" preceding nouns used herein do not limit the number, and may be "multiple" as needed. This variation in number is also within the scope of protection, as will be explained below. 【0009】 Please refer to Figures 1 to 6, which show one embodiment of the present invention. The positioning device of the present invention comprises a base 1 and a positioning structure 2. 【0010】 The base 1 has a plurality of first positioning holes 11 and a plurality of second positioning holes 12 along the assembly direction 7, into which at least one insertion column 81 of the positioning target member 8 is inserted. In the direction perpendicular to the assembly direction 7, the distance between any two adjacent first positioning holes 11 is the first interval 13, and the distance between any two adjacent second positioning holes 12 is the second interval 14. The second interval 14 is smaller than the first interval 13, although this is just one example and not limited to this example. This allows the positioning device to simultaneously accommodate changes in the dimensions / positions of different insertion columns 81 of the positioning target member 8, improving the range of applicability and the degree of freedom of adjustment. In this embodiment, there are multiple insertion columns 81, and as shown in Figure 6, all of the multiple insertion columns 81 are inserted into the plurality of first positioning holes 11. Alternatively, in another usage configuration shown in Figure 7, all of the insertion columns 81 are inserted into the multiple second positioning holes 12. Alternatively, in yet another usage configuration, each of the insertion columns 81 is inserted into at least one first positioning hole 11 and at least one second positioning hole 12. 【0011】 The positioning structure 2 includes a plurality of positioning assemblies 21 and one interlocking gear 24 housed within the base 1, each positioning assembly 21 including a rod body 3 and a positioning block 4, the rod body 3 being mounted on the base 1 laterally with respect to the assembly direction 7 and rotatable about its own axis, the positioning block 4 being screwed onto the rod body 3 and movable along the axial direction of the rod body 3 to a locked position, and the positioning block 4 being driven to move linearly by rotating the rod body 3, thereby achieving the objectives of reducing the number of parts, simplifying operation, and saving space. When the positioning block 4 is in the locked position, a portion of the positioning block 4 is configured to enter at least one of the plurality of first positioning holes 11 and the plurality of second positioning holes 12 to engage the at least one insertion column 81, and the rod bodies 3 of the plurality of positioning assemblies 21 and the interlocking gear 24 mesh with each other to form an interlocking relationship, and by operating the rod body 3 of any of the positioning assemblies 21, the positioning blocks 4 of the plurality of positioning assemblies 21 can be driven synchronously, thereby shortening the positioning time and avoiding tilting or loosening due to asynchronous locking on each side. 【0012】 Preferably, the number of the positioning assemblies 21 is equal to the number of side walls of the base 1, thereby allowing them to be driven from various different directions and angles, and to be locked from multiple lateral directions. The rod body 3 of each positioning assembly 21 is inserted into the base 1 perpendicular to the side wall of the base 1. 【0013】 In this embodiment, the base 1 is rectangular, there are four positioning assemblies 21, and the interlocking gear 24 is a bevel gear located in the center of the base 1 and functions as the interlocking center, thereby effectively distributing torque and shortening the transmission path. The positioning structure 2 further includes a slide groove 5 and a cover plate 6, the slide groove 5 is opened in the base 1 and the rod body 3 and the positioning block 4 are housed in the slide groove 5, the cover plate 6 is positioned on the base 1 so as to shield the slide groove 5 and thereby effectively prevents the intrusion of dust and chips, the end of the rod body 3 away from the interlocking gear 24 is positioned on the cover plate 6 and is provided with a drive unit 31, which can rotate the rod body 3 by external operation. 【0014】 An even number of first positioning holes 11 are provided on opposite sides of the rod body 3 of any positioning assembly 21, and an even number of second positioning holes 12 are provided on opposite sides of the rod body 3 of any positioning assembly 21, thereby allowing the positioning block 4 to form symmetrical locking points on the rod body 3, reducing vibrations caused by forces from one side, and improving clamping stability and positioning accuracy with respect to the insertion column 81. 【0015】 The positioning block 4 includes a coaxially arranged first portion 41 and a second portion 45, the second portion 45 protruding from the first portion 41, the first portion 41 having two first locking portions 42 on both radial sides of the rod body 3, and the second portion 45 having two second locking portions 46 on both radial sides of the rod body 3, and when the positioning block 4 is in the locked position, the two first locking portions 42 enter into the two first positioning holes 11 and the two second locking portions 46 enter into the two second positioning holes 12. In short, since the first positioning holes 11 and the second positioning holes 12 correspond simultaneously on a single positioning block 4, the positioning operation can be completed in a single step. 【0016】 Each first positioning hole 11 has an inner diameter different from that of each second positioning hole 12. Each first locking portion 42 has two first inclined surfaces 43 on opposite sides in the assembly direction 7, and each first inclined surface 43 forms a first angle 44 with respect to the radial direction of the rod body 3. Each second locking portion 46 has two second inclined surfaces 47 on opposite sides in the assembly direction 7, and each second inclined surface 47 forms a second angle 48 with respect to the radial direction of the rod body 3, and the second angle 48 is different from the first angle 44. 【0017】 In this embodiment, the inner diameter of each first positioning hole 11 is larger than the inner diameter of each second positioning hole 12, and the angle of the first clamping angle 44 is larger than the angle of the second clamping angle 48. By controlling the depth to which the first locking portion 42 enters the first positioning hole 11 and the depth to which the second locking portion 46 enters the second positioning hole 12, it is ensured that the amount of movement and the tightening pressure generated after locking are equal. 【0018】 The plurality of first positioning holes 11 form a grid arrangement of a plurality of first squares 15 with a first spacing 13, and the outermost contour of the grid formed by the plurality of first positioning holes 11 forms a first rectangle 17. The plurality of second positioning holes 12 form a grid arrangement of a plurality of second squares 16 with a second spacing 14, and the outermost contour of the grid formed by the plurality of second positioning holes 12 forms a second rectangle 18, which is located entirely within the first rectangle 17. This arrangement provides regular and predictable hole position coordinates within a limited area, which is useful for rapid position selection and automatic alignment. Furthermore, the second rectangle 18 is completely positioned within the first rectangle 17, forming a two-layer hole region structure with a rough outer surface (the first positioning hole 11) and a narrow inner surface (the second positioning hole 12). This allows the outer region (the first positioning hole 11) to position larger dimensions and the inner region (the second positioning hole 12) to position smaller dimensions. 【0019】 The number of the plurality of the first squares 15 is odd, and the number of the plurality of the second squares 16 is odd. The first square 15 located at the center and the second square 16 located at the center are arranged concentrically. Thereby, the other first squares 15 / second squares 16 are symmetrically developed with the center as the reference, facilitating high-speed alignment with the center, reducing the cumulative error, and enabling the force-receiving and positioning references to be more consistent with the concentric structure, improving the alignment consistency of the positioning. 【0020】 The plurality of positioning assemblies 21 can be further defined as two first positioning assemblies 22 and two second positioning assemblies 23. The two first positioning assemblies 22 are symmetrically arranged along the long side of the first rectangle 17, and the two second positioning assemblies 23 are symmetrically arranged along the short side of the first rectangle 17. The form of the first positioning assembly 22 is different from that of the second positioning assembly 23. In particular, the length of the positioning block 4 of each first positioning assembly 22 is greater than the length of the positioning block 4 of each second positioning assembly 23. Furthermore, they can synchronously enter / exit the plurality of first positioning holes 11 and the plurality of second positioning holes 12 at different positions with the same moving amount. 【0021】 In this embodiment, the difference between the length of the positioning block 4 of each first positioning assembly 22 and the length of the positioning block 4 of each second positioning assembly 23 is equal to the difference between the first interval 13 and the second interval 14. Furthermore, the user can provide an optimal locking structure according to the stiffness requirements in the long side and short side directions, the operating torque, or the difference in the force received by the insertion post 81. Also, when viewed from each first rectangle 17 / each second rectangle 18, at least one first positioning assembly 22 and at least one second positioning assembly 23 will lock the plurality of insertion posts 81 of the positioning target member 8 from different directions, thereby achieving the purpose of strengthening in a local direction and adjusting the balance of the overall structure, further improving the resistance to eccentric loads and the stable locking effect. 【Explanation of Reference Numerals】 【0022】 1 Base 11 First positioning hole 12 Second positioning hole 13 First interval 14 Second interval 15 First square 16 Second square 17 First rectangle 18 Second rectangle 2 Positioning structure 21 Positioning assembly 22 First positioning assembly 23 Second positioning assembly 24 Interlocking gear 3 Rod body 31 Driving part 4 Positioning block 41 First part 42 First locking part 43 First inclined surface 44 First included angle 45 Second part 46 Second locking part 47 Second inclined surface 48 Second included angle 5 Slide groove 6 Cover plate 7 Assembly direction 8 Positioning target member 81 Insertion post
