[0025] Refer to the following Figures 1 to 7 An automatic positioning workbench and machining system according to some embodiments of the present application are described.

[0026] See also Figures 1 to 7 As shown, an embodiment of the first aspect of the present application provides an automatic positioning workbench for positioning and fixing a material to be processed 4 during machining. The automatic positioning workbench includes a machining platform 1, a diagonal adjustment assembly, and a plurality of limit push blocks 21. The diagonal adjustment assembly and the limit push blocks 21 are both arranged on the machining platform 1. The diagonal adjustment assembly includes an adjustment clamping block 31 and a driving portion. The adjustment clamping block 31 is capable of clamping a predetermined edge of the material to be processed 4.

[0027] The automatic positioning workbench provided according to the above technical features effectively solves the problems existing in traditional workbenches through the coordinated design of the diagonal adjustment component and multiple limit push blocks 21. The adjustment clamp 31 of the diagonal adjustment component can accurately clamp the predetermined edge of the material 4 to be processed, and cooperate with the transmission of the drive unit to accurately push the material to the specified position, so that the multiple limit push blocks 21 are respectively fitted with different side walls of the material, thereby realizing the three-dimensional positioning of the material, greatly improving the positioning accuracy, and meeting the requirements of high-precision machining and the consistency of part processing accuracy. At the same time, the automatic positioning process does not require repeated manual adjustments, reduces the manual operation links, significantly improves the operating efficiency, and reduces labor intensity. In addition, this positioning method has good adaptability to materials 4 to be processed of different sizes. It only needs to adjust the parameters of the drive unit to achieve rapid positioning and fixation of materials of different sizes, thereby enhancing the versatility of the workbench, eliminating the need for customized special fixtures, and reducing the cost of equipment procurement and use.

[0028] like Figure 3As shown in the figure, an example of the material to be processed 4 is a cube. Correspondingly, the four sides of the cube can be the first side wall 41, the second side wall 42, the third side wall 43 and the fourth side wall 44, respectively. The predetermined edge is formed by the intersection of the third side wall 43 and the fourth side wall 44.

The first adjustment unit connects the connecting plate 315 and the first clamping arm 311 to adjust the angle between the connecting plate 315 and the first clamping arm 311. The second adjustment unit connects the connecting plate 315 and the second clamping arm 312 to adjust the angle between the connecting plate 315 and the second clamping arm 312. In this way, by adjusting the swing angle between the first clamping arm 311 and the second clamping arm 312 and the connecting plate 315, the setting angle of the material to be processed 4 relative to the processing platform 1 can be effectively adjusted, thereby making the first side wall 41 and the second side wall 42 mate with the corresponding limit push block 21 respectively.

[0030] Preferably, if Figures 1 to 5 As shown, the first clamping arm 311 is provided with a first fitting surface for fitting with the third side wall 43, and the second clamping arm 312 is provided with a second fitting surface for fitting with the fourth side wall 44. The angle between the first fitting surface and the second fitting surface is consistent with the angle of the predetermined edge, so as to ensure the clamping stability and tightness of the predetermined edge by the adjustment clamping block 31.

[0031] Preferably, if Figures 1 to 5 As shown, the ends of the first clamping arm 311 and the second clamping arm 312 can be connected to the middle of the connecting plate 315, and the ends of the first fitting surface and the second fitting surface close to each other are connected to each other, so as to ensure the stability of the adjustment clamping block 31 and the stability of the angle between the first fitting surface and the second fitting surface.

[0032] Preferably, if Figure 4 and Figure 5As shown, the above-mentioned first adjustment part shell may include a first telescopic wall 313, a first adjustment airbag 318 and a first air inlet hole 316. The first telescopic wall 313 connects the first clamping arm 311 and the end of the connecting plate 315 close to the first clamping arm 311. The connecting plate 315, the first telescopic wall 313 and the first clamping arm 311 are surrounded to form the first adjustment airbag 318. The first air inlet hole 316 is connected to the first adjustment airbag 318. In this way, the first adjustment airbag 318 can be connected to the gas driving component (for example, an airbag, an air pump, an air compressor, etc.) through the first air inlet hole 316, so as to change the volume of the first adjustment airbag 318 by inflating and deflating the first adjustment airbag 318, thereby pushing the first clamping arm 311 to deflect relative to the connecting plate 315, so as to realize the rotation of the material 4 to be processed by pushing the third side wall 43.

[0033] Similarly, if Figure 4 and Figure 5 As shown, the above-mentioned second adjustment part shell may include a second telescopic wall 314, a second adjustment airbag 319 and a second air inlet hole 317. The second telescopic wall 314 connects the second clamping arm 312 and the end of the connecting plate 315 close to the second clamping arm 312. The connecting plate 315, the second telescopic wall 314 and the second clamping arm 312 are surrounded to form the second adjustment airbag 319. The second air inlet hole 317 is connected to the second adjustment airbag 319. In this way, the second adjustment airbag 319 can be connected to the gas driving component (for example, an airbag, an air pump, an air compressor, etc.) through the second air inlet hole 317, so that the volume of the second adjustment airbag 319 can be changed by inflating and deflating the second adjustment airbag 319, thereby pushing the second clamping arm 312 to deflect relative to the connecting plate 315, so as to realize the rotation of the material 4 to be processed by pushing the fourth side wall 44.

[0034] Preferably, although not shown in the figures, the automatic positioning workbench may further include the above-mentioned gas driving member to control the inflation and deflation of the above-mentioned first adjustment airbag 318 and the second adjustment airbag 319 through the gas driving member.

[0035] Preferably, if Figure 5 As shown, the first adjustment airbag 318 is similar to a triangular prism-shaped space structure, and the first telescopic wall 313 can be a side wall of the triangular prism-shaped space structure, so that the first adjustment airbag 318 can push the first clamping arm 311 to deflect.

[0036] Similarly, if Figure 5 As shown, the second adjustment airbag 319 is also similar to a triangular prism-shaped spatial structure, and its structure and beneficial effects are similar to those of the first adjustment airbag 318, which will not be repeated here.

[0037] Preferably, if Figure 5As shown, the first telescopic wall 313 and the second telescopic wall 314 may both be folding telescopic structures, that is, a structure formed by repeatedly folding a plate or sheet material and capable of telescoping along a predetermined direction.

[0038] Preferably, if Figure 5 As shown, the connecting plate 315 , the first clamping arm 311 , the second clamping arm 312 , the first telescopic wall 313 and the second telescopic wall 314 may be an integrated connecting member.

[0039] Optionally, the adjustment clamp 31 may be a rubber piece, a plastic piece, a resin piece, etc.

[0040] In an embodiment, preferably, Figures 1 to 3 As shown, the driving portion may include a linear driving member 32 , which is connected to the adjusting clamp 31 to drive the adjusting clamp 31 to move closer to and away from the material 4 to be processed, thereby facilitating the material 4 to be processed to enter and move out of the processing platform 1 .

[0041] Preferably, the linear drive member 32 may be a pneumatic cylinder, an electric cylinder or other linear drive devices.

[0042] Preferably, if Figures 1 to 3 As shown, the above-mentioned driving part can also include a rotating driving member 33, and the above-mentioned linear driving member 32 is arranged on the processing platform 1 via the rotating driving member 33 to drive the adjustment clamp 31 to rotate with the axis perpendicular to the axis of the processing platform 1. In this way, the angle of the above-mentioned adjustment clamp 31 is adjusted by the rotating driving member 33, so that even if the relative processing position deflection is large when the material to be processed 4 is placed on the processing platform 1, the angle of the clamp 31 can be adjusted by rotating the clamp 31 so that the predetermined edge of the material to be processed 4 can enter between the first clamping arm 311 and the second clamping arm 312, and the rotation of the rotating driving member 33 drives the material to be processed 4 to initially abut against the limit module.

[0043] Optionally, the rotation driving member 33 may be a rotation driving device such as an electric turntable or a rotating table.

[0044] In an embodiment, preferably, Figure 1 、 Figure 6 and Figure 7 As shown, the limiting push block 21 is provided with an abutting plane 210 , and the limiting push block 21 contacts the material to be processed 4 via the abutting plane 210 . In other words, the abutting plane 210 is the side surface where the limiting push block 21 contacts the first side surface or the second side surface.

[0045] Preferably, the above-mentioned limit push block 21 may include multiple pressure collection parts 22, and the pressure collection parts 22 are arranged at intervals on the abutment plane 210 to judge whether the material to be processed 4 is in contact with the abutment plane 210 through the pressure difference between the multiple pressure collection parts 22, thereby realizing the automatic positioning workbench to automatically judge whether the material to be processed 4 is placed in place, thereby improving the accuracy of the automatic positioning workbench in positioning the material to be processed 4 and the efficiency of judging whether the automatic positioning workbench is in place.

[0046] like Figure 1 As shown in the figure, an example is shown in which three pressure collection parts 22 are provided on the abutting plane 210. The three pressure collection parts 22 are spaced apart and arranged in a direction parallel to the processing platform 1. However, this is not limited to this example. As long as the tightness of the contact between the abutting plane 210 and the material 4 to be processed can be determined, the number of pressure collection parts 22 provided on the abutting plane 210 can also be 2, 4, 5, 6, or more.

[0047] Preferably, the pressure collection unit 22 can be respectively connected to communicate with the rotation drive unit and the gas drive unit, so as to adjust the rotation direction of the rotation drive unit through the pressure information collected by the pressure collection unit 22, and control the gas drive unit to inflate the first adjustment airbag 318 and deflate the second adjustment airbag 319 or to deflate the first adjustment airbag 318 and inflate the second adjustment airbag 319.

[0048] Preferably, if Figure 1 、 Figure 6 and Figure 7 As shown, the above-mentioned limit push block 21 may include a limit plate 211 and a placement plate 212 connected to each other, the above-mentioned abutment plane 210 is arranged on one side of the limit plate 211, and the limit push block 21 is arranged on the processing platform 1 via the placement plate 212. In this way, the L-shaped structure formed by the limit plate 211 and the placement plate 212 effectively improves the setting stability of the limit push block 21 on the processing platform 1.

[0049] Preferably, if Figure 6 and Figure 7 As shown, the above-mentioned limit plate 211 is provided with a placement hole 213 passing through the limit plate 211, and the pressure collection part 22 is arranged in the placement hole 213. On the one hand, it avoids the additional space occupied by the pressure collection part 22 and ensures the tightness of the abutment plane 210 and the material to be processed 4; on the other hand, it ensures the setting stability of the pressure collection part 22 and reduces the probability of accidental scratches and collisions damaging the pressure collection part 22.

[0050] Preferably, if Figure 6 and Figure 7As shown, the pressure collection part 22 may include a probe 221, a reset part 222 and a pressure sensor 223. The pressure sensor 223 is fixed to the end of the placement hole 213 away from the abutment plane 210. The probe 221 is arranged at the end of the placement hole 213 close to the abutment plane 210, and the probe 221 can extend and retract relative to the abutment plane 210. One end of the reset part 222 abuts the inner wall of the placement hole 213, and the other end of the reset part 222 is connected to the probe 221 to provide power for the probe 221 to extend relative to the abutment plane 210. When the probe 221 retracts relative to the abutment plane 210, the probe 221 contacts the collection point of the pressure sensor 223. In this way, the placement hole 213 plays a good guiding and supporting role for the probe 221 and the reset part 222, ensuring that the probe 221 will not deviate or get stuck during the extension and retraction process, thereby ensuring that the pressure sensing function is stable and reliable. At the same time, the pressure sensor 223 is fixed inside the mounting hole 213, avoiding its direct exposure to the external processing environment, reducing the risk of damage to the sensor due to external factors such as cutting fluid and metal debris, effectively extending the service life of the pressure acquisition part 22, reducing equipment maintenance costs, and enhancing the durability and stability of the automatic centering workbench in actual processing scenarios.

[0051] Preferably, if Figure 6 and Figure 7 As shown, the pressure collecting part 22 may further include a fixing seat 224, which may be arranged at one end of the mounting hole 213 facing away from the abutting plane 210, and the pressure sensor 223 may be embedded in the fixing seat 224 to fix the pressure sensor 223 and the limiting plate 211 through the fixing seat 224.

[0052] Preferably, if Figure 7As shown, the above-mentioned placement hole 213 may include a first section and a second section connected to each other, the first section is arranged on the side where the abutting plane 210 is located, and the aperture of the first section is smaller than the aperture of the second section to form a limiting boss at the connection between the first section and the second section. The outer side of the probe 221 is provided with a first limiting protrusion 2211, and the reset portion 222 is provided on the side of the first limiting protrusion 2211 facing away from the abutting plane 210. When the probe 221 is extended relative to the abutting plane 210, the first limiting protrusion 2211 and the limiting boss are abutted. On the one hand, through the cooperation between the limiting boss and the first limiting protrusion 2211, the probe 221 and the seating hole 213 are limited to prevent the probe 221 from falling out of the end of the seating hole 213 close to the abutting plane 210; on the other hand, when the probe 221 is extended relative to the abutting plane 210, the first limiting protrusion 2211 can abut against the limiting boss. In other words, the outer diameter of the above-mentioned first limiting protrusion 2211 is larger than the aperture of the above-mentioned first section. In this way, the first section of the seating hole 213 can be blocked by the first limiting protrusion 2211, thereby effectively improving the sealing performance of the seating hole 213 to the pressure sensor 223.

[0053] Furthermore, if Figure 7 As shown, an annular slot 2131 is provided on the side of the limiting boss facing the first limiting protrusion 2211. The probe 221 may further include a sealing edge 2212 provided on the side of the first limiting protrusion 2211 facing the limiting boss, at least a portion of which can extend into the annular slot 2131. Thus, by providing the corresponding plug-in connection between the sealing edge 2212 and the annular slot 2131, on the one hand, the path for external debris or water vapor to enter the placement hole 213 from the end of the placement hole 213 close to the abutment plane 210 is effectively extended, further improving the sealing performance of the placement hole 213 with respect to the pressure sensor 223. On the other hand, the plug-in guiding effect of the annular slot 2131 and the sealing edge 2212 effectively ensures that the probe 221 will not deviate or get stuck during the extension and retraction process, thereby ensuring that the pressure sensing function is stable and reliable.

[0054] Preferably, although not shown in the figures, the pressure collection unit 22 may further include a sealing ring disposed between the probe 221 and the inner wall of the placement hole 213, further improving the sealing performance of the placement hole 213 with respect to the pressure sensor 223. On the one hand, the plug-in fit between the sealing edge 2212 and the annular slot 2131 forms a primary seal between the placement hole 213 and the pressure collection unit 22; on the other hand, the sealing ring blocks the probe 221 from the inner wall of the placement hole 213, forming a secondary seal between the placement hole 213 and the pressure collection unit 22. Thus, the two-stage sealing structure effectively prevents debris, water vapor, cutting chips, etc. from entering the placement hole 213 and coming into contact with the pressure sensor 223 during the machining process, thereby increasing the service life of the pressure sensor 223.
