DETAILED DESCRIPTION

[0026] To facilitate understanding of the present invention, a more comprehensive description of the present invention will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to facilitate a more thorough and comprehensive understanding of the disclosure of the present invention.

[0027] It should be noted that when an element is referred to as being “fixed to” another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being “connected to” another element, it may be directly connected to the other element or there may be an intermediate element.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0029] like Figures 1 to 5As shown, one embodiment of the present invention relates to a multi-station disc-type positioning device for metal processing, comprising a base plate 1, a jig plate 2, and a positioning disc 3. The jig plate 2 is disposed on the base plate 1, and the positioning disc 3 is formed on the jig plate 2 by machining. The positioning disc 3 comprises an outer disc body 31, an inner disc body 32, and a positioning element 33. The outer disc body 31 is provided with a first adsorption surface 311, and the inner disc body 32 is provided with a second adsorption surface 321. The height of the first adsorption surface 311 is lower than that of the second adsorption surface 321. The positioning element 33 is provided on the second adsorption surface 321. The first adsorption surface 311 is provided with a plurality of first adsorption holes 312, and the second adsorption surface 321 is provided with a plurality of second adsorption holes 322. This embodiment provides a stable foundation support for the entire positioning system by combining the base plate 1 and the jig plate 2. The jig plate 2 is directly disposed on the base plate 1. This design not only simplifies the installation process, but also effectively ensures the stability of the jig plate 2 during the processing, avoiding positioning errors caused by shaking or displacement. Secondly, the layered structure of the outer and inner disks 31 and 32, as well as the height difference between the first and second suction surfaces 311 and 321, provide more flexible positioning options for metal workpieces of varying sizes. The first suction surface 311 is located at a lower position, suitable for smaller or lighter workpieces; while the second suction surface 321 is located at a higher position and, with the support of the positioning element 33, can more stably secure larger or heavier workpieces. This layered design greatly expands the application range of the positioning device and meets diverse processing needs. Furthermore, the multiple first suction holes 312 and second suction holes 322 provided on the first and second suction surfaces 311 and 321, respectively, not only enhance the suction force between the workpiece and the positioning disk 3 but also ensure the stability and accuracy of the workpiece during processing. The negative pressure effect generated by the suction holes allows the workpiece to be securely attached to the positioning disk 3, effectively preventing slippage or deviation during processing, thereby improving processing accuracy. Furthermore, the provision of the positioning element 33 further enhances positioning accuracy. They typically have precise dimensions and shapes, enabling them to fit specific areas on a workpiece, enabling more precise positioning. This not only helps improve machining efficiency but also reduces scrap and production costs while ensuring product quality.

[0030] The base plate 1 is an aluminum alloy base plate 1, and fixed grooves 11 are provided on both sides of the base plate 1 for inserting screws to fix the base plate 1. In this embodiment, aluminum alloy, as a lightweight and high-strength material, not only reduces the weight of the entire positioning device, but also ensures the stability and durability of the base plate 1. The design of the fixed grooves 11 on both sides of the base plate 1 cleverly solves the problem of fixing the base plate 1. By inserting screws into these grooves, the base plate 1 can be firmly locked to ensure its precise positioning and stable operation in the multi-station disc positioning device. It also facilitates the installation and disassembly of the base plate 1, thereby improving work efficiency. During the metal processing process, workers can quickly fix the base plate 1 in the desired position with screws and start processing without complicated adjustments.

[0031] The base plate 1 is provided with a mounting surface 12, on which a mounting hole 13 is provided, and the jig plate 2 is provided with a countersunk hole 27, which is opposite to the mounting hole 13 for inserting a screw so that the jig plate 2 is fixed on the mounting surface 12. Specifically, a first ventilation groove 21 and a second ventilation groove 22 are provided on the side of the jig plate 2 that is in contact with the mounting surface 12, one end of the first ventilation groove 21 is connected to the first adsorption hole 312, and one end of the second ventilation groove 22 is connected to the second adsorption hole 322. In this embodiment, the mounting surface 12 on the base plate 1 and the precisely arranged mounting holes 13 provide a reference for the assembly of the jig plate 2, ensuring positioning accuracy. The clever correspondence between the countersunk hole 27 and the mounting hole 13 allows the screw to smoothly penetrate and fix the jig plate 2, which not only improves the stability of the structure, but also effectively avoids the interference of the protrusion of the screw head on the operating space, ensuring the smoothness of the processing process. Furthermore, the first and second ventilation grooves 21 and 22, designed on the side of the fixture plate 2 that contacts the mounting surface 12, are connected to the first and second adsorption holes 312 and 322, respectively. This innovative design significantly optimizes ventilation efficiency. During the metalworking process, workpieces can be quickly adsorbed and secured, improving both processing efficiency and stability. This ventilation structure also aids in heat dissipation, extending the life of the device.

[0032] A first pneumatic interface 23 and a second pneumatic interface 24 are provided on both sides of the jig plate 2. The first pneumatic interface 23 is used to connect to the first vent groove 21, and the second pneumatic interface 24 is used to connect to the second vent groove 22. Specifically, the jig plate 2 is provided with a first sealing ring 25 on the outside of the first vent groove 21, and a second sealing ring 26 on the outside of the first vent groove 21. The first sealing ring 25 and the second sealing ring 26 are both used to seal between the jig plate 2 and the base plate 1. In this embodiment, the precise connection between the first pneumatic interface 23 and the first vent groove 21, and the stable docking between the second pneumatic interface 24 and the second vent groove 22 ensure the smoothness and efficiency of the gas flow path. At the same time, the first sealing ring 25 and the second sealing ring 26 cleverly provided on both sides of the jig plate 2 effectively enhance the sealing performance between the jig plate 2 and the base plate 1, avoid gas leakage, and thus improve the airtightness and processing accuracy of the entire device. This design not only optimizes gas transmission efficiency, but also significantly reduces processing errors caused by gas leakage, ensuring the stability and accuracy of the metal processing process.

[0033] The first adsorption surface 311 is provided with a micro-concave groove 313, and the micro-concave groove 313 is used to connect the ports of multiple first adsorption holes 312. Specifically, a positioning recessed hole 323 is provided on the second adsorption surface 321. In this embodiment, the design of the micro-concave groove 313 can effectively connect the ports of multiple first adsorption holes 312 to each other, thereby achieving uniform distribution and efficient transmission of adsorption force. This not only enhances the adsorption stability of the device on the workpiece, but also greatly improves the positioning accuracy during the processing. At the same time, the positioning recessed hole 323 provided on the second adsorption surface 321 further enhances the functionality of the device. The positioning recessed hole 323 matches the corresponding structure on the workpiece, ensuring that the workpiece is accurately fixed in position during the processing process and reducing the processing error caused by position offset.

[0034] The positioning element 33 includes a positioning sleeve 331, on which a positioning pin 332 is provided. The positioning sleeve 331 is used to fix the positioning shaft on the second adsorption surface 321. Specifically, a guide bevel 333 is provided at the end of the positioning pin 332. In this embodiment, the positioning sleeve 331 in the positioning element 33, in conjunction with the positioning pin 332 thereon, effectively achieves accurate and stable axial fixation of the positioning shaft on the second adsorption surface 321. This design not only improves the positioning accuracy, but also ensures the stability and consistency between each workstation during the processing, which is crucial for ensuring the quality of the workpiece. In particular, the guide bevel 333 provided at the end of the positioning pin 332, this detail optimization greatly facilitates the assembly and calibration process of the positioning sleeve 331. The guide bevel 333 can guide the positioning pin 332 to smoothly enter the predetermined position, reducing friction and resistance during assembly, thereby improving assembly efficiency.

[0035] The above embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the concept of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
