[0002] In automated machining lines, it is often necessary to use transfer robots to place products to be processed into fixtures. In actual operation, the transfer robot is only responsible for placing the products onto the fixtures; it cannot, like a human, determine whether the bottom surface of the product accurately aligns with the fixture's supports or surfaces, leading to inaccurate machining precision. If manual checks of the alignment accuracy are required after each product placement, it wastes labor costs and hinders the development of automated machining processes. Utility Model Content

[0031] Furthermore, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.
[0032] Please also refer to Figure 1-6 This utility model provides a fixture with an airtight placement detection function, including a fixture 1. An airtight placement detection mechanism 3 for placing the product to be processed is provided on the base plate 2 of the fixture 1. The airtight placement detection mechanism 3 is connected to an external airtightness tester (not shown) through an air inlet channel 21 provided on the side of the base plate 2, so as to detect whether the product to be processed is accurately placed on the fixture 1 through the airtightness principle.
[0033] The airtightness testing mounting mechanism 3 includes a support 31, a chip removal rod 32, a return spring 33, a connecting steel cable 34, and a cylinder 35. The chip removal rod 32 and the return spring 33 are installed in the support 31. One end of the connecting steel cable 34 is connected to the chip removal rod 32 and the other end is connected to the cylinder 35, so that the cylinder 35 can pull the chip removal rod 32 through the connecting steel cable 34.
[0034] The support base 31 is fixed to the base plate 2 of the fixture 1 by fasteners. The support base 31 is provided with a detection air passage 311 and an assembly cavity 312 that are interconnected along the axial direction for assembling the chip removal rod 32 and the return spring 33. The side of the support base 31 is provided with a limit screw 313. The limit screw 313 is inserted laterally into the assembly cavity 312 of the support base 31 and abuts against the chip removal rod 32. The limit screw 313 is used to limit the chip removal rod 32, so that the chip removal rod 32 moves back and forth in the assembly cavity 312, thereby preventing the chip removal rod 32 from rotating.
[0035] Furthermore, an exhaust channel 314 is also laterally opened on the other side of the support 31 opposite to the limiting screw 313. The exhaust channel 314 is connected to the assembly cavity 312 of the support 31 and is used to discharge the detection gas when not in the detection state.
[0036] Preferably, a sealing ring is provided at the bottom of the support seat 31 at the outlet of the assembly cavity 312 to seal the gap between the support seat 31 and the base plate 2 and improve airtightness.
[0037] The chip removal rod 32 includes a top rod portion 321, a cutting portion 322, and a connecting rod portion 323 connected as one piece. In the initial state, the top rod portion 321 is located in the detection air passage 311 of the support seat 31 and its end protrudes above the top surface of the support seat 31. The cutting portion 322 and the connecting rod portion 323 are located in the assembly cavity 312 of the support seat 31. The side wall of the cutting portion 322 facing the limiting screw 313 is machined into a cutting platform 324. The limiting screw 313 abuts against the cutting platform 324 of the chip removal rod 32, thereby preventing the chip removal rod 32 from rotating inside the assembly cavity 312 of the support seat 31.
[0038] Since the chip removal rod 32 has a flat cutting platform 324 on the side wall at the cutting section 322, the fitting gap between the chip removal rod 32 installed in the support 31 and the assembly cavity 312 of the support 31 forms an air passage, so that the detection gas can flow from the assembly cavity 312 of the support 31 to the detection air passage 311 of the support 31 through the air passage.
[0039] Furthermore, a shaft seal 325 is also fitted on the flattened portion 322 of the chip removal rod 32. The shaft seal 325 is used to cooperate with the exhaust channel 314 of the support 31. In the detection state, the shaft seal 325 blocks the exhaust channel 314, allowing the detection gas to flow to the detection air passage 311 of the support 31. In the non-detection state, the shaft seal 325 is in the position where the exhaust channel 314 is not blocked, and the detection gas is discharged from the exhaust channel 314, avoiding the airtightness tester from misjudging the product's arrival status due to chip blockage.
[0040] Preferably, a first cable groove is provided on the connecting rod portion 323 of the chip removal rod 32, and one end of the connecting steel cable 34 is fitted into the first cable groove to prevent slippage between the connecting steel cable 34 and the chip removal rod 32.
[0041] The return spring 33 is sleeved on the connecting rod portion 323 of the chip remover 32 and is limited in the assembly cavity 312 of the support seat 31 by a limiting ring. One end of the return spring 33 abuts against the cut flat portion 322 of the chip remover 32, and the other end abuts against the limiting ring. The function of the return spring 33 is to allow the chip remover 32, which is subjected to external force downward, to return to its original position after the external force is released.
[0042] The cylinder 35 is fixed on the clamp 1 by the cylinder seat. The output shaft of the cylinder 35 is provided with a second cable groove. The other end of the connecting steel cable 34 is fitted into the second cable groove to prevent the connection between the connecting steel cable 34 and the cylinder 35 from slipping. The cylinder 35 pulls the chip removal rod 32 downward through the connecting steel cable 34. When the cylinder 35 releases the pulling force, the return spring 33 causes the chip removal rod 32 to return to its original position.
[0043] The working principle or workflow of the fixture tooling with airtight seating detection function in this case is as follows:
[0044] A. Initial free state:
[0045] All parts are in the initial state after reset. At this time, the top rod 321 of the chip remover 32 is inserted into the air measuring channel of the support 31. The shaft seal 325 of the chip remover 32 does not block the exhaust channel 314 of the support 31. The connecting steel cable 34 is in a slack state. The detection gas of the external air tightness tester flows in from the air inlet channel 21 on the base 2 and flows into the assembly cavity 312 from the gap between the support 31 and the chip remover 32. It is discharged from the exhaust channel 314 of the support 31.
[0046] B. Product testing status:
[0047] The robot places the product to be processed onto the fixture 1. The bottom surface of the product first contacts the top rod 321 of the chip remover 32. Under the buffering action of the return spring 33, the product continues to slide down until the bottom surface of the product contacts the top surface of the support 31.
[0048] The output end of cylinder 35 retracts and drives the chip removal rod 32 downward through the connecting steel cable 34. The chip removal rod 32 descends until the top rod part 321 disengages from the detection air passage 311, so that the assembly cavity 312 is connected to the detection air passage 311. At this time, the shaft seal 325 of the chip removal rod 32 blocks the exhaust passage 314 of the support seat 31. The detection gas of the external air tightness tester flows in from the air inlet passage 21 on the base 2 and flows into the assembly cavity 312 and the detection air passage 311 through the mating gap between the support seat 31 and the chip removal rod 32. If the air tightness tester detects that the detection air passage 311 of the support seat 31 is blocked by the bottom surface of the product, it indicates that the product has been placed in place. If the air tightness tester detects that the detection air passage 311 of the support seat 31 is not blocked by the bottom surface of the product, it indicates that the product has not been placed in place.
[0049] C. Chip removal status:
[0050] The cylinder 35 drives the chip removal rod 32 downward, so that the assembly cavity 312 of the support seat 31 is connected to the detection air passage 311. The detection gas is discharged from the detection air passage 311 and blows away the waste chips. After the cylinder 35 releases its force, under the action of the return spring 33, the top rod part 321 of the chip removal rod 32 returns to the original position and moves upward to the detection air passage 311 of the support seat 31, which can also push out any waste chips that may exist in the detection air passage 311.
[0051] Compared to existing technologies, the fixture tooling with airtight placement detection function in this case determines whether the product is accurately placed by detecting the airtightness between the bottom surface of the product and the top surface of the support, which is conducive to the construction of machining automation; it eliminates the need for secondary manual inspection to ensure the product is accurately placed, effectively saving labor costs; the support is equipped with a chip removal bar driven by a cylinder to promptly remove waste chips from the detection air passage, ensuring the accuracy of airtightness detection.
[0052] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
