[0033] In order to better understand the technical solutions and beneficial effects of the present disclosure, the present disclosure is further described in detail below with reference to specific embodiments:

[0034] See also Figures 1 to 7 The universal fixture 10 for cutting and processing of one embodiment of the present invention includes a base plate 100, a support assembly 200 and a positioning assembly 300. The base plate 100 is fixedly connected to the workbench. The support assembly 200 includes a stackable support column 210, one end of which is provided with a fixing portion 211, and the stackable support column 210 is detachably connected to the base plate 100 via the fixing portion 211. The positioning assembly 300 includes a positioning base 310, a positioning pin 320 and a profiling block 330, one end of the positioning pin 320 is provided with a connecting portion (not shown), the connecting portion (not shown) is connected to the positioning base 310, the positioning pin 320 is connected to the base plate 100 via the positioning base 310, the other end of the positioning pin 320 is used to position the workpiece, the profiling block 330 is detachably connected to the stackable support column 210, and the profiling block 330 is used to position the side wall of the workpiece.

[0035] In this embodiment, by stacking the support assembly 200, the height of the positioning assembly 300 is adjusted, thereby adjusting the overall height of the universal cutting and processing fixture 10, which facilitates design and practical application, thereby improving the versatility of the universal cutting and processing fixture 10 and adapting to diverse needs. At the same time, the support assembly 200 and the base plate 100 are detachably connected, which facilitates the disassembly and adjustment of the position of the support assembly 200, adapting to diverse needs and improving the versatility of the universal cutting and processing fixture 10. In addition, the base plate 100 and the support assembly 200 are universal parts. When changing production, only the positioning assembly 300 needs to be replaced, which improves the versatility and convenience of the universal cutting and processing fixture 10; at the same time, it reduces storage costs.

[0036] like Figures 1 to 3 As shown, in one embodiment, the stackable support column 210 is screwed to the base plate 100 via the fixing portion 211 .

[0037] It is understood that the threaded connection between the stackable support column 210 and the base plate 100 facilitates assembly and disassembly of the stackable support column 210, enabling quick adjustment or replacement, and improving the flexibility of the universal cutting and processing fixture 10. Furthermore, the threaded connection can withstand heavy loads, ensuring the stability of the stackable support column 210 and enhancing the safety of the universal cutting and processing fixture 10. Furthermore, the threaded connection allows for the selection of different thread types and sizes to meet varying production requirements, further enhancing the adaptability of the universal cutting and processing fixture 10.

[0038] like Figures 1 to 3 As shown, in one embodiment, the base plate 100 defines a first threaded hole 110, into which the fixing portion 210 of the stackable support column 210 is threaded. It will be appreciated that the first threaded hole 110 in the base plate allows the stackable support column 210 to be installed directly on the base plate 100, facilitating position adjustment. This also simplifies the overall structural design and reduces manufacturing and maintenance costs.

[0039] Specifically, in this embodiment, the first threaded hole 110 is an M8 threaded through hole, the fixing portion 211 is an M8 screw with a length of 10 mm, and the number of the first threaded holes 110 and the number of the stackable support columns 210 are both multiple.

[0040] like Figure 2 and Figure 3As shown, in one embodiment, a stackable support column 210 is provided with a stacking portion 212 at one end thereof facing away from the fixed portion 211. The number of stackable support columns 210 is at least two, and the fixed portion 211 of one stackable support column 210 is detachably connected to the stacking portion 212 of another stackable support column 210. It is understood that by connecting the stackable support columns 210, different production needs can be met, eliminating the need for the universal cutting and processing fixture 10 to rely on a single fixed structure, thereby improving the versatility of the universal cutting and processing fixture 10. Furthermore, the detachable connection facilitates adjustment of the number of stacking portions, allowing the universal cutting and processing fixture 10 to adapt to different production needs.

[0041] like Figures 1 to 3 As shown, in one embodiment, the superposition portion 212 is provided with a second threaded hole 212a, and the fixing portion 210 of one superimposable support column 210 is screwed to the superposition portion 212 of another superimposable support column 210. It can be understood that,

[0042] By screwing the fixed portion of the stackable support column 210 to the stacking portion 212, a more stable connection can be achieved. This connection method effectively enhances the stability of the entire support structure, can better withstand external loads, and avoids loosening or deformation during use.

[0043] like Figure 1 As shown in the figure, the base plate 100 defines a first threaded hole 110, into which the fixing portion 211 of the stackable support column 210 is threaded. The diameter of the first threaded hole 110 is equal to the diameter of the second threaded hole 212a. It is understood that both the first threaded hole 110 and the second threaded hole 212a can be directly connected to the fixing portion 211. In this way, the stackable support column 210 does not require a separate base column and stacking column, allowing for direct use without distinction. This reduces the number of parts, facilitates installation and adjustment of the support assembly 200, and enhances the flexibility of the universal cutting fixture 10.

[0044] like Figure 1 、 Figure 4 and Figure 5 As shown, in one embodiment, the universal fixture for cutting and processing 10 further includes an error-proofing component 400, which includes a gas detection support column 410 and a sensor (not shown). One end of the gas detection support column 410 is provided with an air outlet 412, and the side wall of the gas detection support column 410 is provided with an air inlet 413 connected to the air outlet 412. The sensor is connected to the air inlet 413. One end of the gas detection support column 410 is provided with a mounting portion 410 on the other end facing away from the air outlet 412. The gas detection support column 410 is detachably connected to the base plate 100 via the mounting portion 410. Specifically, in this embodiment, the sensor is an air sensor, and the air connector of the air sensor is installed in the air inlet 413. The gas flows from the air inlet 413 to the air outlet 412.

[0045] When the workpiece is placed at the predetermined position, the workpiece blocks the air outlet 412 of the gas inspection support column 410 and prevents the gas from flowing out. The air sensor sends a signal, indicating that the position is correct and the operation can be carried out.

[0046] When the placement of the workpiece deviates, the workpiece cannot block the air outlet 412 of the air inspection support column 410, and the air sensor has no signal output, that is, the placement is wrong, and manual adjustment of the placement position is required.

[0047] Furthermore, after the workpiece is placed in the predetermined position, the correct position is confirmed by the sensor signal. Once correctly placed, the workpiece can be locked to the base plate 100 using a connecting fixture below the nozzle to support the nozzle. This eliminates the need for a clamping device to meet the placement and support requirements of the workpiece, facilitates manual placement, and effectively saves time required for loading and unloading.

[0048] like Figure 6 As shown, in one embodiment, the positioning pin 320 includes a pin 321 and a fixing member 322. A positioning hole 3211 is defined at one end of the pin 321 away from the connecting portion (not shown). The fixing member 322 is located in the positioning hole 2311 and connected to the workpiece. The pin 321 is located in the positioning base 320 and connected to the base plate 100. It is understood that by replacing different types of pins 321 and fixing members 322, the processing requirements of various workpieces can be effectively adapted, thereby improving the flexibility and adaptability of the universal cutting and processing fixture 10 and meeting diverse production requirements.

[0049] like Figure 1 As shown, in one embodiment, two mutually perpendicular coordinate indicator strips 130 are provided on the periphery of the base plate 100. Both coordinate indicator strips 130 include multiple indicators 131. Specifically, in this embodiment, the two coordinate indicator strips 130 are located above and on the left side of the base plate 100, respectively. The spacing between two adjacent indicators 131 is 25 mm, and one mounting port corresponds to one indicator 131 in each of the two indicator strips. This facilitates redesigning the position of the support assembly 200 and positioning assembly 300 according to actual production needs, improving the adaptability of the fixture. Furthermore, it facilitates adjustment or replacement of the support assembly 200 and positioning assembly 300, reducing errors and meeting the positioning requirements of the cut workpiece.

[0050] like Figure 1 and Figure 7As shown, in one embodiment, the shaped block 330 defines a plurality of through holes 331, through which the shaped block 330 is detachably connected to the stackable support column 210. It will be appreciated that by defining through holes in the shaped block 330 and using connectors to connect the shaped block 330 to the stackable support column 210, the structure of the shaped block 330 can be simplified, reducing manufacturing and maintenance costs.

[0051] Furthermore, the plurality of through holes 331 are respectively provided at different positions of the profiling block 330, so that the load applied to the profiling block can be evenly distributed, thereby improving the stability of the universal fixture 10 for cutting and processing.

[0052] like Figure 1 and Figure 7 As shown, in one embodiment, the profiling block 330 is provided with a plurality of relief grooves 332, each of which is connected to a corresponding through-hole 331. Specifically, in this embodiment, the stacking portion 212 of the stackable support column 210 is a second threaded hole 212a, and the connecting member 212a is located within the relief grooves 332 and connected to the second threaded hole 212a of the stackable support column 210. It will be appreciated that providing the connecting member above the profiling member 330 facilitates the installation, removal, and adjustment of the profiling block 330, improving operational efficiency and thereby enhancing the flexibility and practicality of the universal cutting fixture 10.

[0053] Furthermore, the length of the avoidance groove 332 is less than the distance between two adjacent first threaded holes 110. The avoidance groove 332 provides an adjustable distance for the profiling block 330, thereby improving the flexibility and adaptability of the universal cutting processing fixture 10, ensuring that it can be quickly adjusted to meet specific needs in different cutting tasks.

[0054] Compared with the prior art, the present disclosure has at least the following advantages:

[0055] By stacking support components, the height of the positioning assembly can be adjusted, thereby adjusting the overall height of the universal cutting jig. This facilitates design and practical application, thereby increasing the versatility of the universal cutting jig and adapting to diverse needs. Furthermore, the detachable connection between the support assembly and the base plate facilitates the removal and adjustment of the support and positioning assemblies, adapting to diverse needs and improving the versatility of the universal cutting jig. Furthermore, the base plate and support assembly are universal parts, so only the positioning assembly needs to be replaced when making production changes, improving the versatility and convenience of the universal cutting jig while also reducing storage costs.

[0056] The above-described embodiments merely represent several implementation methods of the present disclosure. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that a person of ordinary skill in the art could make various modifications and improvements without departing from the scope of the present disclosure, all of which fall within the scope of protection of the present disclosure.
