[0079] The following is a detailed description of various embodiments of the present invention in conjunction with the accompanying drawings.

[0080] See also Figure 1 and Figure 2The embodiment of the utility model further provides a positioning device 1000, comprising a base 200, a cover plate 300 and a fixing mechanism 100. The base 200 has a lower through hole 200a and is used to carry the material 400, and the cover plate 300 has an upper through hole 300a corresponding to the lower through hole 200a. The fixing mechanism 100 is used to fix the cover plate 300 to the base 200, so that the cover plate 300 presses the material 400 to the base 200. Among them, the middle part of the material 400 has a structural hole 400a.

[0081] Specifically, the base 200 includes a bracket 210 having a hollow groove 210a and a bottom plate 220 disposed on the bracket 210. The bottom plate 220 is provided with a bottom hole 220a, which penetrates the bottom plate 220 and communicates with the hollow groove 210a of the bracket 210. The hollow groove 210a and the bottom hole 220a together form a lower through hole 200a.

[0082] In this embodiment, the two opposite side walls of the upper through hole 300a are respectively provided with extensions 310, which are recessed downward relative to the top surface of the cover plate 300, so that the fixing mechanism 100 acts on the extensions 310 to press the cover plate 300 downward. In other embodiments, there may be only one extension 310.

[0083] For ease of description, Figures 2 to 4 A three-dimensional coordinate system is added in the decomposition. Specifically, the Z-axis direction is the first direction, the X-axis direction is the second direction, and the Y-axis direction is the third direction. The Z-axis direction, the Y-axis direction, and the Z-axis direction are perpendicular to each other.

[0084] See also Figure 3 and Figure 4 In some embodiments, the fixing mechanism 100 includes a mounting seat 110, a fixing member 120, a movable member 130, a lifting driving member 140 and two sets of locking components 150.

The mounting seat 110 is provided with a mounting through hole 110a, which penetrates the mounting seat 110 along the Z-axis direction and is used to correspond to the upper through hole 300a in the Z-axis direction. For example, the cross section of the mounting through hole 110a is square. The fixing member 120 is connected to the mounting seat 110 and is sequentially arranged with the mounting seat 110 along the Z-axis direction. The movable member 130 is slidably connected with the fixing member 120 along the Z-axis direction.

[0085] The two sets of locking components 150 are symmetrically arranged relative to the central axis direction of the installation through hole 110a. Each set of locking components 150 includes a linkage member 151, a connecting member 152 and a holding member 153. One end of the linkage member 151 is rotatably connected to the movable member 130, and the other end of the linkage member 151 is rotatably connected to one end of the holding member 153. The connecting member 152 is movably arranged in the middle of the linkage member 151 and is rotatably connected to the side wall of the installation through hole 110a. The other end of the holding member 153 has a holding portion 153a that is compatible with the extension portion 310. The lifting drive member 140 is connected to the movable member 130. The lifting drive member 140 is used to drive the movable member 130 to rise or fall along the Z-axis direction, so that the movable member 130 drives the two holding members 153 to rotate through the two linkage members 151, thereby causing the two holding portions 153a to rise to move away from the base 200, or causing the two holding portions 153a to fall to hold the two extension portions 310. Please refer to Figure 3 and Figure 4 In some embodiments, the fixing member 120 is provided with a receiving groove 120a, the receiving groove 120a is connected to the mounting through hole 110a, and the opposite side walls of the receiving groove 120a are respectively provided with guide grooves 120b, and each guide groove 120b is arranged along the Z-axis direction. The movable member 130 includes a movable body 131 and a guide rod 132, the movable body 131 can be movably received in the receiving groove 120a, the guide rod 132 is penetrated in the movable body 131, one end of the guide rod 132 is movably penetrated in one of the linkage members 151 and extends into one guide groove 120b, and the other end of the guide rod 132 is movably penetrated in another linkage member 151 and extends into another guide groove 120b.

[0086] Therefore, the movable member 130 is slidably connected to the fixed member 120 along the Z-axis direction by the structure in which the guide rod 132 is movably inserted into the two guide grooves 120 b. The structure is simple and the assembly of the fixing mechanism 100 is convenient.

[0087] In this embodiment, the two holding portions 153a are arranged at intervals along the X-axis direction. Correspondingly, when the cover plate 300 is placed on the bottom plate 220 of the base 200, the two extension portions 310 of the cover plate 300 are arranged at intervals along the X-axis direction, the connecting member 152 is movably penetrated in the linkage member 151 along the Y-axis direction, the two guide grooves 120b are arranged at intervals along the Y-axis direction, and the guide rod 132 is penetrated in the movable body 131 along the Y-axis direction. In other embodiments, the two holding portions 153a may also be arranged at intervals along the Y-axis direction. Correspondingly, when the cover plate 300 is placed on the bottom plate 220 of the base 200, the two extension portions 310 of the cover plate 300 are arranged at intervals along the Y-axis direction, the connecting member 152 is movably penetrated in the linkage member 151 along the X-axis direction, the two guide grooves 120b are arranged at intervals along the X-axis direction, and the guide rod 132 is penetrated in the movable body 131 along the X-axis direction.

[0088] In some embodiments, each guide groove 120 b extends to the surface of the fixing member 120 facing the mounting seat 110 , and the mounting seat 110 is covered by the two guide grooves 120 b .

[0089] Therefore, the guide groove 120b extends to the top surface of the fixing member 120, which can facilitate the installation of the movable member 130, and the mounting seat 110 covers the two guide grooves 120b, which can form a stop for the guide rod 132 of the movable member 130 in the Z-axis direction.

[0090] See also Figure 4 and Figure 5 In some embodiments, the pressing member 153 includes a pressing body 1531 and a rotating rod 1532. The pressing portion 153a is disposed at one end of the pressing body 1531, the connecting member 152 is movably disposed in the middle of the pressing body 1531 along the Y-axis direction, and the rotating rod 1532 is rotatably disposed in the other end of the pressing body 1531 and the corresponding linkage member 151.

[0091] Therefore, the rotation connection between the holding member 153 and the linkage member 151 is realized by inserting the rotation rod 1532, which has a simple structure and low manufacturing cost.

[0092] In some embodiments, each pressing body 1531 is substantially L-shaped, and the openings 1531 a of the two pressing bodies 1531 are disposed opposite to each other.

[0093] Therefore, through the above arrangement, on the basis of satisfying the requirement of pressing the extension portion 310 in the Z-axis direction, the space occupied by the pressing body 1531 in the Z-axis direction can be reduced, which is beneficial to the miniaturization of the locking assembly 150 .

[0094] In some embodiments, the pressing body 1531 has a receiving groove 1531 b at one end away from the pressing portion 153 a , and the rotating rod 1532 is rotatably disposed through the bottom wall of the receiving groove 1531 b and the corresponding linkage member 151 .

[0095] Therefore, the receiving groove 1531 b can reduce the space occupied by the connection between the pressing body 1531 and the rotating rod 1532 in the Y-axis direction, which is beneficial to the miniaturization of the locking assembly 150 .

[0096] In some embodiments, each set of locking components 150 further includes a roller 154. The roller 154 is movably sleeved on the corresponding connecting member 152, and is used for rolling against the pressing member 153 where another connecting member 152 is located.

[0097] Therefore, the roller 154 can form a rolling resistance against the pressing body 1531 of the pressing member 153 , which is beneficial to improving the rotation stability of the pressing body 1531 .

[0098] See also Figure 3 and Figure 4 In some embodiments, the mounting base 110 includes a first mounting member 111 and a second mounting member 112. The first mounting member 111 is used to be inserted into the lower through hole 200a and detachably connected to the base 200. The first mounting member 111 is provided with a first receiving groove 111a. The second mounting member 112 is used to be inserted into the lower through hole 200a and detachably connected to the base 200. The second mounting member 112 is provided with a second receiving groove 112a on a side facing the first mounting member 111. The first receiving groove 111a and the second receiving groove 112a are connected to form the mounting through hole 110a. The fixing member 120 is connected to at least one of the first mounting member 111 and the second mounting member 112.

[0099] Therefore, the size and shape of the mounting through hole 110a can be quickly adjusted by adjusting the size and shape of the first receiving groove 111a and the second receiving groove 112a, which is beneficial to improving the applicable types of the mounting through hole 110a.

[0100] In some embodiments, the lifting drive member 140 includes a lifting rod 141 and a driving body 142. The lifting rod 141 is disposed in the receiving groove 120a and connected to the movable body 131, and the driving body 142 is disposed in the fixing member 120 and connected to the lifting rod 141, and is used to drive the lifting rod 141 to drive the movable body 131 to rise and fall. In this embodiment, the lifting drive member 140 is a cylinder.

[0101] The working process of the positioning device 1000 in the above embodiment is roughly as follows:

[0102] First, the driving body 142 drives the lifting rod 141 to drive the movable member 130 to rise, so that the movable member 130 drives the two holding members 153 to rotate through the two linkage members 151, so that the holding portions 153a of the two holding members 153 rise along the Z-axis direction to move away from the base 200, and the two holding portions 153a are moved closer to each other along the X-axis direction;

[0103] Then, the material 400 having the structural hole 400a in the middle is placed on the bottom plate 220 of the base 200, and the structural hole 400a of the material 400 corresponds to the mounting through hole 110a of the mounting seat 110 in the Z-axis direction, and the material 400 is sleeved on the two sets of locking components 150 through the structural hole 400a;

[0104] Subsequently, the cover plate 300 is placed on the material 400, and the upper through hole 300a of the cover plate 300 corresponds to the structural hole 400a of the material 400 in the Z-axis direction, so that the material 400 is loaded. At this time, the cover plate 300 is sleeved on the two holding members 153 through the upper through hole 300a.

[0105] Finally, the driving body 142 drives the lifting rod 141 to drive the movable member 130 to descend along the Z-axis direction, so that the movable member 130 drives the two holding members 153 to rotate through the two linkage members 151, so that the holding portions 153a of the two holding members 153 descend along the Z-axis direction and approach each other along the X-axis direction to hold the two extension portions 310, thereby positioning the material 400 and forming the following: Figure 6 Status shown.

[0106] Therefore, in the above-mentioned positioning device 1000 and fixing mechanism 100, the lifting drive member 140 drives the movable member 130 to rise or fall, so as to respectively realize the placement and positioning of the material 400 with the structural hole 400a in the middle, thereby simplifying the positioning process and improving the positioning efficiency of the material 400 with the structural hole 400a in the middle.
