[0034] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0035] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0036] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0037] In modern manufacturing, precise positioning and fixing of workpieces are crucial for ensuring processing quality and efficiency. Especially in high-precision machining and automated production lines, the performance of positioning devices directly impacts product accuracy and production efficiency. Traditional positioning devices typically rely on complex mechanical structures and manual operation, which is not only cumbersome and inefficient but also difficult to adapt to workpieces of different shapes and sizes, resulting in poor flexibility and adaptability of the production line.

[0038] In related technologies, mechanical clamps and adsorption methods are used to position the workpiece. However, mechanical clamps and adsorption methods are insufficient in terms of positioning accuracy and stability, making it difficult to meet the requirements of high-precision machining.

[0039] See Figures 1 to 5 In order to solve the technical problems existing in the related technologies, this application provides a positioning device 10 for fixing the workpiece 20 to be processed.

[0040] See Figure 3 The workpiece 20 to be processed has a first positioning part 21 defined at one end in the first direction X, and a second positioning part 22 defined at the other end.

[0041] It should be noted that the first positioning part 21 and the second positioning part 22 are existing structures on the workpiece 20 to be processed, such as protrusions, claws, positioning pins, etc. The positioning device 10 of this application utilizes the existing structure of the workpiece 20 to achieve positioning of the workpiece 20. It is understood that the shape of other positions of the workpiece 20 to be processed is not limited here.

[0042] See Figures 1 to 5 The positioning device 10 includes: a base 100, a sliding base 200, a pressure plate 300, and at least one first driving mechanism 400; the sliding base 200 is defined with a slot 210 and a groove 220 extending along a first direction X, the slot 210 and the groove 220 being connected; the sliding base 200 is provided with a plurality of placement seats 500 for placing the workpiece 20 to be processed at intervals along a second direction Y; the first driving mechanism 400 is disposed on the base 100 and is used to drive the pressure plate 300 to move along a third direction Z to press the workpiece 20 to be processed. The output shaft 420 of the first drive mechanism 400 passes through the slide groove 220 and is connected to the pressure plate 300; the sliding seat 200 can move along the first direction X under the action of external force so that the output shaft 420 of the first drive mechanism 400 switches between the slide groove 220 and the slot 210; when the output shaft 420 of the first drive mechanism 400 is in the slide groove 220, the second positioning part 22 of the workpiece 20 is disengaged from the pressure plate 300; when the output shaft 420 of the first drive mechanism 400 is in the slot 210, the second positioning part 22 of the workpiece 20 is in contact with the pressure plate 300.

[0043] In this context, the first direction X, the second direction Y, and the third direction Z are all perpendicular to each other. "Perpendicular" can be understood as the angle between two lines, between a line and a surface, or between two surfaces being 89° to 91°. Equal distances or equal angles refer to a tolerance range of 1% to 1%.

[0044] According to the technology of this application, when it is necessary to position the workpiece 20, the user first pushes the sliding seat 200 to move along the first direction X, so that the output shaft 420 of the first drive mechanism 400 slides from the slot 210 to the end of the slide groove 220 away from the slot 210. During this process, the placement seat 500 can move away from the pressure plate 300, so that the placement seat 500 is away from the pressure plate 300, so that there is more space above the placement seat 500 to place the workpiece 20. Then, the workpiece 20 is placed on the placement seat 500 on the sliding seat 200, and the sliding seat 200 is pushed to move along the first direction X, so that the output shaft 420 of the first drive mechanism 400 slides from the end of the slide groove 220 away from the slot 210 into the slot 210. During this process, the placement seat 500 can move toward the pressure plate 300 so that the placement seat 500 is close to the pressure plate 300. Finally, the first drive mechanism 400 drives the pressure plate 300 to move along the third direction Z to press the workpiece 20. When the pressure plate 300 presses the workpiece 20, the second positioning part 22 of the workpiece 20 abuts against the pressure plate 300, so that the positioning device 10 of this application can fix the workpiece 20 by pressing the workpiece 20 with the pressure plate 300 and by the second positioning part 22 of the workpiece 20 abutting against the pressure plate 300. After the workpiece 20 is processed, the first drive mechanism 400 drives the pressure plate 300 to move away from the workpiece 20 along the third direction Z. This causes the pressure plate 300 to move away from the workpiece 20, pushing the sliding seat 200 to move along the first direction X. This causes the output shaft 420 of the first drive mechanism 400 to slide from the slot 210 to the end of the slide groove 220 away from the slot 210. During this process, the placement seat 500 can move away from the pressure plate 300, allowing it to move away from the pressure plate 300. At this point, the workpiece 20 above the placement seat 500 can be removed. Based on this, this application can achieve dual positioning of the workpiece 20, improving the positioning accuracy of the workpiece 20. Multiple placement seats 500 are spaced apart on the sliding seat 200 to simultaneously fix multiple workpieces 20. Secondly, the positioning device 10 is easy to operate. The workpiece 20 can be fixed and released by moving the sliding seat 200 and starting the first drive mechanism 400 through external force, which reduces the difficulty of operation and is suitable for industrial automation applications.

[0045] In some embodiments, the width of the slide groove 220 in the second direction Y is equal to or slightly larger than the diameter of the output shaft 420 of the first drive mechanism 400, so that the pressure plate 300 does not vibrate excessively when the output shaft 420 of the first drive mechanism 400 slides in the slide groove 220. Further, receiving grooves are respectively provided on both sides of the connection between the slide groove 220 and the slot 210 in the second direction Y, and elastic protrusions are respectively provided in the two receiving grooves. When the output shaft 420 of the first drive mechanism 400 passes the connection between the slide groove 220 and the slot 210, the elastic protrusions are pressed into the corresponding receiving grooves, so that the output shaft 420 of the first drive mechanism 400 can switch between the receiving groove and the slot 210.

[0046] In this embodiment, the two elastic protrusions and the slot 210 enclose a receiving space that is adapted to the shape of the output shaft 420 of the first drive mechanism 400, so that when the output shaft 420 of the first drive mechanism 400 is inserted into the slot 210, the output shaft 420 of the first drive mechanism 400 and the pressure plate 300 cannot move relative to each other.

[0047] For example, the elastic protrusion includes a spring and a limiting block. One end of the spring is connected to the bottom of the receiving groove, and the other end of the spring is connected to the limiting block. The opposite ends of the two limiting blocks are arc-shaped so that when the limiting block contacts the output shaft 420 of the first drive mechanism 400, the output shaft 420 of the first drive mechanism 400 can press the limiting block into the receiving groove.

[0048] In some embodiments, see Figure 4 The placement seat 500 has a positioning hole 510 that is adapted to the first positioning part 21 at one end adjacent to the sliding seat 200. When the workpiece 20 to be processed is placed on the placement seat 500, the first positioning part 21 can be inserted into the first positioning part 21 of the placement seat 500 to achieve rough positioning of the workpiece 20 to be processed.

[0049] In this embodiment of the application, the shape of the positioning hole 510 is adapted to the shape of the first positioning part 21 so that the workpiece 20 cannot move after the first positioning part 21 is engaged in the positioning hole 510.

[0050] In some embodiments, see Figure 5 The first drive mechanism 400 includes at least two cylinders 410. The sliding seat 200 is provided with at least two slots 210 and at least two slide grooves 220. The at least two slots 210, at least two slide grooves 220 and at least two cylinders 410 are correspondingly arranged. The output shafts 420 of the at least two cylinders 410 are respectively connected to the pressure plate 300. The output shafts 420 of the at least two cylinders 410 are slidably arranged in the corresponding slide grooves 220 and slots 210.

[0051] In this embodiment, since the placement base 500 is spaced apart along the second direction Y, when there is only one cylinder 410, the pressure plate 300 is prone to rotate relative to the cylinder 410. This means that when the output shaft 420 of the first drive mechanism 400 is in the slot 210, the second positioning parts 22 of multiple workpieces 20 cannot all simultaneously engage with the pressure plate 300. Therefore, this application effectively prevents the pressure plate 300 from rotating by providing two cylinders 410, with the output shafts 420 of each cylinder 410 connected to the pressure plate 300. The two cylinders 410 act on different positions of the pressure plate 300, and by operating synchronously, the pressure plate 300 can provide a more uniform and powerful clamping force. Compared to a single cylinder 410, the design of two cylinders 410 can better distribute the clamping force and enhance the fixing effect. Secondly, by having two cylinders 410 slide in the corresponding slide grooves 220 and slots 210, the output shaft 420 of the cylinders 410 is avoided, and the sliding accuracy of the pressure plate 300 is improved.

[0052] In some embodiments, the output shafts 420 of at least two cylinders 410 are spaced apart along the second direction Y. By arranging the output shafts 420 of at least two cylinders 410 spaced apart along the second direction Y, the embodiments of this application significantly improve the stability and uniformity of the pressure plate 300, enhance the fixing effect, adapt to the needs of multi-workpiece processing, and improve the reliability and ease of operation and maintenance of the system.

[0053] In some embodiments, see Figure 1 and Figure 2 Multiple pressing blocks 310 are provided on the side of the pressure plate 300 facing the seat 100. The multiple pressing blocks 310 and multiple placement seats 500 are correspondingly arranged. When the output shaft 420 of the first drive mechanism 400 is in the slot 210, the first drive mechanism 400 can drive the pressing blocks 310 to move along the third direction Z to press the workpiece 20 to be processed onto the placement seat 500. In this application, the middle part of the workpiece 20 to be processed is pressed onto the placement seat 500 by the pressing blocks 310, so that the first positioning part 21 and the second positioning part 22 of the workpiece 20 to be processed can be limited by the positioning hole 510 and the pressure plate 300 respectively, and the middle part of the workpiece 20 to be processed is pressed onto the placement seat 500 by the pressing blocks 310, thereby realizing the triple positioning of the workpiece 20 to be processed.

[0054] In some embodiments, a rubber pad is provided at one end of the pressing block 310 facing the placement seat 500, and the rubber pad serves to protect the workpiece 20 to be processed.

[0055] In some embodiments, a gap 520 is defined between the plurality of placement seats 500.

[0056] For example, the gap 520 between two adjacent placement seats 500 needs to be larger than the size of a finger so that there are gaps 520 on both sides of the placement seat 500 in the second direction Y, so that when changing the workpiece 20, the operator can insert two fingers into the gaps 520 on both sides of the placement seat 500 in the second direction Y, so that the user can pick up and put down the workpiece 20.

[0057] In some embodiments, a slider is provided on the side of the sliding seat 200 facing the seat body 100, and a guide groove is provided on the side of the seat body 100 facing the sliding seat 200, with the slider sliding within the guide groove. Alternatively, a slider is provided on the side of the seat body 100 facing the sliding seat 200, and a guide groove is provided on the side of the sliding seat 200 facing the seat body 100, with the slider sliding within the guide groove. This provides clear guidance for the movement of the sliding seat 200 on the seat body 100, preventing offset and wobbling of the sliding seat 200 during the sliding process. The tight fit between the slider and the guide groove ensures accurate movement of the sliding seat 200, reducing errors during the sliding process.

[0058] In some embodiments, this application further includes a positioning pin. A first hole 230 is provided on the sliding seat 200, and a second hole is provided on the seat 100. When the output shaft 420 of the first drive mechanism 400 is in the slot 210, the first hole 230 and the second hole are connected along the third direction Z, and the positioning pin can be inserted into the first hole 230 and the second hole to fix the sliding seat 200 and the seat 100. When the output shaft 420 of the first drive mechanism 400 is in the slot 210, the positioning pin can be inserted into the first hole 230 and the second hole to achieve locking between the sliding seat 200 and the seat 100. When it is necessary to slide the sliding seat 200, the positioning pin can be pulled out of the first hole 230 and the second hole to allow the sliding seat 200 and the seat 100 to move relative to each other.

[0059] In some embodiments, see Figure 1 The workpiece 20 to be processed has a part 23 to be processed at a position corresponding to the first positioning part 21. The pressure plate 300 has a plurality of clearance holes 320. When the output shaft 420 of the first drive mechanism 400 is in the slot 210, the clearance holes 320 correspond to the part 23 to be processed on the workpiece 20, so that the external tool can process the part 23 to be processed through the clearance holes 320.

[0060] It is understood that this application can adapt to workpieces 20 of different sizes and shapes by adjusting the shape and size of the clearance hole 320, and the shape and size of the clearance hole 320 are not limited herein.

[0061] In summary, when it is necessary to position the workpiece 20, the user first pushes the sliding seat 200 to move along the first direction X, so that the output shaft 420 of the first drive mechanism 400 slides from the slot 210 to the end of the slide groove 220 away from the slot 210. During this process, the placement seat 500 can move away from the pressure plate 300, so that the placement seat 500 is away from the pressure plate 300, so that there is more space above the placement seat 500 to place the workpiece 20. Then, the workpiece 20 is placed on the placement seat 500 on the sliding seat 200, and the sliding seat 200 is pushed to move along the first direction X, so that the output shaft 420 of the first drive mechanism 400 slides from the end of the slide groove 220 away from the slot 210 into the slot 210. During this process, the placement seat 500 can move toward the pressure plate 300 so that the placement seat 500 is close to the pressure plate 300. Finally, the first drive mechanism 400 drives the pressure plate 300 to move along the third direction Z to press the workpiece 20. When the pressure plate 300 presses the workpiece 20, the second positioning part 22 of the workpiece 20 abuts against the pressure plate 300, so that the positioning device 10 of this application can fix the workpiece 20 by pressing the workpiece 20 with the pressure plate 300 and by the second positioning part 22 of the workpiece 20 abutting against the pressure plate 300. After the workpiece 20 is processed, the first drive mechanism 400 drives the pressure plate 300 to move away from the workpiece 20 along the third direction Z. This causes the pressure plate 300 to move away from the workpiece 20, pushing the sliding seat 200 to move along the first direction X. This causes the output shaft 420 of the first drive mechanism 400 to slide from the slot 210 to the end of the slide groove 220 away from the slot 210. During this process, the placement seat 500 can move away from the pressure plate 300, allowing it to move away from the pressure plate 300. At this point, the workpiece 20 above the placement seat 500 can be removed. Based on this, this application can achieve dual positioning of the workpiece 20, improving the positioning accuracy of the workpiece 20. Multiple placement seats 500 are spaced apart on the sliding seat 200 to simultaneously fix multiple workpieces 20. Secondly, the positioning device 10 is easy to operate. The workpiece 20 can be fixed and released by moving the sliding seat 200 and starting the first drive mechanism 400 through external force, which reduces the difficulty of operation and is suitable for industrial automation applications.
