[0037] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0038] like Figures 1 to 5 As shown, this utility model provides an automatic positioning device, which includes a support structure 10, a positioning mechanism 20, and a limiting mechanism 30. The support structure 10 includes a support column 11 and a support plate 12. The support column 11 is disposed at a support position, and the support plate 12 is disposed at the top of the support column 11. The positioning mechanism 20 includes a first positioning component 21 and a second positioning component 22. The first positioning component 21 and the second positioning component 22 are respectively fixed to adjacent two sides of the support plate 12. At least two limiting mechanisms 30 are provided, and at least two limiting mechanisms 30 are disposed on the side of the support plate 12 and are respectively corresponding to the first positioning component 21 and the second positioning component 22. The limiting mechanism 30 is configured to be able to clamp the workpiece 100 with the first positioning component 21 along the width direction of the support plate 12 and to clamp the workpiece 100 with the second positioning component 22 along the length direction of the support plate 12.

[0039] In this structure, the workpiece 100 can be placed on the support plate 12, and its two adjacent sides abut against the first positioning component 21 and the second positioning component 22, respectively. Simultaneously, at least two limiting mechanisms 30 can gradually clamp the workpiece 100, thereby positioning and clamping the workpiece 100 along the length and width directions of the support plate 12 (which are also the length and width directions of the workpiece 100). The device has a simple overall structure, low operating cost, and requires no manual intervention. Positioning and clamping are automatically completed after the workpiece 100 is placed on the support plate 12, reducing the error rate and preventing damage to the workpiece 100.

[0040] It should be noted that, as Figure 1 As shown, a plurality of support blocks 15 are spaced apart on the surface of the support plate 12, and the plurality of support blocks 15 are used to support the workpiece 100. In this structure, the support blocks 15 can increase the support height and separate the workpiece 100 from the surface of the support plate 12, thereby preventing the limiting mechanism 30 from rubbing against the surface of the support plate 12 when positioning, thus improving clamping efficiency and positioning convenience.

[0041] In addition, such as Figure 1 and Figure 5 As shown, due to the large length of the workpiece 100, at least two first positioning components 21 are spaced apart along the length of the support plate 12, and the limiting mechanism 30 is correspondingly arranged one-to-one with the first positioning component 21. This arrangement increases the force-bearing points on the long side of the workpiece 100. Combined with the effects of the limiting mechanism 30 and the second positioning component 22, as well as the vertical support of multiple support blocks 15, the stability of the clamping is ensured, the positioning accuracy is significantly improved, and local shaking is avoided.

[0042] The specific structure of the limiting mechanism 30 is as follows: Figures 2-4As shown, the limiting mechanism 30 includes a mounting plate 31, a driving component 32, and a push block 33. The mounting plate 31 is mounted on the support plate 12, and the driving component 32 is connected to the mounting plate 31. The output section of the driving component 32 is connected to the push block 33 for transmission, so as to drive the push block 33 to clamp or disengage from the workpiece 100. This configuration is not only simple in structure but also easy to install. The push block 33 can clamp the workpiece 100 simply by extending or retracting the driving component 32, thereby achieving a good positioning effect together with the first positioning component 21 and the second positioning component 22.

[0043] Considering the limited space on the top surface of the support plate 12, therefore... Figures 2-4 As shown, the mounting plate 31 has a through hole along its thickness direction, the driving member 32 is connected to the bottom of the mounting plate 31, the push block 33 is movably disposed at the top of the mounting plate 31, and the push block 33 has an inclined push groove 331 inside; the limiting mechanism 30 also includes a push rod 34, the push rod 34 includes a rod body 341 and a rod head 342 that are inclined to each other, the rod body 341 passes through the through hole and one end abuts against the output end of the driving member 32, the rod head 342 is slidably disposed in the inclined push groove 331, when the output end of the driving member 32 extends and pushes the rod body 341 upward, the rod head 342 can generate a thrust that makes the push block 33 move in the horizontal direction. This configuration allows the vertical output of the drive unit 32 to be transmitted to the push rod 34, and the rod body 341 moves vertically while the rod head 342 slides along the extension direction of the inclined push groove 331. At the same time, the push block 33 is given an upward thrust through the inner wall of the inclined push groove 331. This thrust can be decomposed into vertical and horizontal components. The horizontal component can drive the push block 33 to slide horizontally on the surface of the mounting plate 31, thereby achieving the purpose of clamping or releasing the workpiece 100. The vertical motion is successfully converted into horizontal motion, thus allowing the drive unit 32 to be placed at the bottom of the mounting plate 31, effectively reducing the structural burden on the surface of the support plate 12.

[0044] like Figure 4 As shown, one side of the rod head 342 is completely flush with the inner wall of the inclined push groove 331, while the other side has an avoidance hole 343 at the connection point with the rod body 341. The completely flush side not only ensures the stability of the sliding motion but also effectively transmits the thrust. The avoidance hole 343 prevents interference between the connection point of the rod head 342 and the rod body 341 and the inner wall of the inclined push groove 331, thus ensuring that the rod head 342 can slide within the inclined push groove 331 when the rod body 341 moves vertically.

[0045] In addition, such as Figure 4As shown, the inner wall of the inclined push groove 331 near the clearance hole 343 is provided with a clearance angle 332. This arrangement not only simplifies the connection structure between the push rod 34 and the push block 33, but also cooperates with the clearance hole 343 to form a good anti-interference or jamming effect, thereby ensuring the stability and smoothness of positioning and clamping.

[0046] like Figure 3 As shown, a limiting plate 35 is provided at the top of the push block 33, which blocks the slot of the inclined push groove 331 away from the mounting plate 31. In this structure, the limiting plate 35 limits the maximum movement distance of the rod head 342, which is also equivalent to limiting the maximum movement distance of the push block 33, thereby indirectly limiting the maximum clamping force of the limiting mechanism 30. This avoids damage to the workpiece 100 due to excessive clamping force, and improves operational safety while ensuring positioning accuracy.

[0047] Furthermore, the end of the push block 33 used to clamp the workpiece 100 is made of a flexible material. This arrangement can provide good buffering and protection when positioning and clamping the workpiece 100, and when the clamping force gradually increases, the clamping end can deform to a certain extent, thereby protecting the workpiece 100 again.

[0048] like Figure 1 and Figure 5 As shown, the support structure 10 also includes a base 13, and two support columns 11 spaced apart along the length of the base 13. The support plate 12, the base 13, and the two support columns 11 together form a receiving space 14, in which multiple driving components 32 are housed. In this structure, the base 13 increases the contact area at the support position, while the two support columns 11 further improve the stability of the support structure 10. The receiving space 14 can just accommodate the driving components 32 of multiple limiting mechanisms 30, thus fully improving space utilization and ensuring the compactness of the structure.

[0049] It should be noted that the push block 33 is detachably connected to the mounting plate 31, and the mounting plate 31 is detachably mounted on the support plate 12. The drive component 32 is connected to the bottom of the mounting plate 31 through the limiting sleeve 36. This detachable connection not only facilitates subsequent maintenance and parts replacement, but also makes it easier to adjust the installation position, improving operational flexibility.

[0050] Furthermore, in this embodiment, the driving component 32 is a cylinder. Cylinders have a simple structure, are inexpensive, and are easy to install, further reducing the overall cost of the device. In other embodiments, structures such as telescopic motors can be used; this embodiment does not impose any other limitations.

[0051] Referring to the accompanying drawings, the working process of the automatic positioning device in this embodiment is described as follows:

[0052] First, the workpiece 100 is placed on the multiple support blocks 15 of the support plate 12, and the two sides of the workpiece 100 abut against the first positioning component 21 and the second positioning component 22 respectively.

[0053] Secondly, multiple drive components 32 are activated, and push blocks 33 are indirectly pushed to move horizontally through push rods 34 until workpiece 100 is clamped, thus completing automatic clamping and positioning;

[0054] Finally, after the operation is completed, the output ends of the multiple drive components 32 retract, the multiple push blocks 33 disengage from the workpiece 100, and the workpiece 100 can be removed.

[0055] In summary, the automatic positioning device in this embodiment is not only simple in structure and low in cost, but also requires no manual intervention and can automatically complete the clamping and positioning of the workpiece 100, thereby reducing operational errors and avoiding damage.

[0056] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
