[0014] A method for press-fit testing using a press-fit testing device includes the following steps:

[0015] S1. The No. 1 vibratory plate vibrates the fastening sleeve into the No. 1 direct vibrator and then into one of the placement slots. The No. 1 sensor detects the positive and negative positions of the fastening sleeve in the placement slot. Then, the No. 1 rotary cylinder drives the No. 1 plate to rotate, so that the fastening sleeve is gripped by the No. 1 rotary cylinder jaw 508. When the result detected by the No. 1 sensor is that the position of the fastening sleeve is reversed, the No. 1 rotary clamp rotates the fastening sleeve 180°. Otherwise, it does not rotate. Then, the fastening sleeve is placed on the floating fixture.

[0016] S2. The floating fixture rotates with the turntable and corresponds to the size of the fastening sleeve and the through hole detection mechanism. Then, the first camera detects whether the sleeve hole of the fastening sleeve is open, and the second camera detects the outer diameter of the fastening sleeve.

[0017] S3. The floating fixture rotates with the turntable to correspond with the fastening sleeve gauge detection mechanism. Under the premise of the fastening sleeve size and through hole detection mechanism, the first cylinder drives the first sliding plate to move down, so that the first sliding plate presses on the top of the product and the floating fixture is pressed tight. Then the third slide cylinder drives the first motor to move down. After the gauge extends into the fastening sleeve, the first motor rotates to ensure that the gauge reaches the bottom. After the gauge reaches the bottom, the fourth displacement sensor detects the depth value of the gauge extending into the sleeve hole of the fastening sleeve.

[0018] S4. The second cylinder drives the second sliding plate to move downward, so that the second limit plate presses the fastening sleeve, thus pressing the floating fixture. Then, the fifth slide cylinder drives the second motor to align the stop gauge with the sleeve hole of the fastening sleeve. If the stop gauge cannot be inserted into the sleeve hole after the second motor drives the stop gauge to rotate, it means that the stop gauge inspection is qualified.

[0019] S5. The floating fixture rotates with the turntable to correspond with the copper core feeding mechanism. Under the premise that the stop gauge inspection mechanism has passed the inspection, the No. 2 vibratory plate transports the copper core to the No. 2 direct vibrator. Then, the No. 6 slide cylinder drives the No. 7 slide cylinder to move above the copper core. The No. 7 slide cylinder drives the No. 2 rotary cylinder jaws to move down and clamp the copper core. After that, the No. 7 slide cylinder drives the No. 2 rotary cylinder jaws to reset. The No. 6 slide cylinder continues to drive the No. 7 slide cylinder to move above the floating fixture. Then, the No. 7 slide cylinder drives the No. 2 rotary cylinder jaws to place the copper core in the fastening sleeve.

[0020] S6. The floating fixture rotates with the turntable to correspond with the pressing mechanism. With the copper core placed in the fastening sleeve, the No. 3 cylinder drives one end of the connecting rod to move down, causing the connecting rod to drive the guide rod to move up. At this time, the copper core is located in the conical hole, and the fastening sleeve is located outside the conical hole. Then, the servo press drives the contour pressing head to press down.

[0021] S7. After the copper core and fastening sleeve are pressed together, the floating fixture moves with the turntable to correspond with the scratch detection mechanism, and the No. 3 camera detects whether there are scratches on the upper surface of the copper core.

[0022] S8. After the scratch detection mechanism passes the inspection, the floating fixture moves with the turntable to correspond with the spacing detection mechanism. Then, the cylinder of the No. 8 slide table drives the mounting plate to move down. At this time, the lower end of the abutment rod abuts against the upper end of the copper core and slides upward along the linear bearing until the support plate presses down on the product and the floating fixture is pressed tight. The No. 1 displacement sensor detects the distance the abutment rod moves upward. The distance between the upper end of the copper core and the upper end of the fastening sleeve is obtained by subtracting the original distance of the abutment rod extending from the lower end of the support plate.

[0023] S9. After the floating fixture moves with the turntable to correspond with the copper core through-hole detection mechanism, and the spacing detection mechanism passes the test, the cylinder of slide nine drives the connecting plate to move down, causing the needle gauge to move towards the through-hole of the copper core. When the needle gauge can smoothly extend into the through-hole of the copper core, the product is qualified; when the needle gauge cannot extend into the through-hole of the copper core, the needle gauge drives the first and second positioning blocks to move up through the upper and lower clamping blocks, compressing the second and third springs. At this time, the product is unqualified.

[0024] S10. The receiving mechanism collects the products.

[0025] Beneficial effects of the invention:

[0026] Before pressing, checking the fastening sleeve with go and no-go gauges can effectively complete the pressing of the copper core and the fastening sleeve, and can also effectively detect whether the copper core is qualified after pressing, thereby improving the product yield and saving production costs.

[0027] The design and implementation of the pressing mechanism can effectively ensure that the copper core and the fastening sleeve are correctly aligned during pressing, thereby improving the accuracy and efficiency of pressing.

[0028] The upper clamping block 1307 and the lower clamping block 1309 can effectively clamp the needle gauge. At the same time, the first conical protrusion 1314 and the first conical groove cooperate, and the second conical protrusion 1315 and the second conical groove cooperate, which can reduce the vibration and damage of the needle gauge 1309 when it encounters a defective copper core, and can quickly reset.

[0047] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0048] like Figure 1 and Figure 15As shown in the embodiment of this application, a press-fitting inspection device is provided, the structure of which includes a frame 1, a turntable 2, an indexing device 3 for driving the turntable 2 to rotate, and a floating fixture 4 circumferentially arranged on the turntable 2. The frame 1 is circumferentially arranged with a fastening sleeve feeding mechanism 5, a fastening sleeve size and through hole inspection mechanism 6, a fastening sleeve go gauge inspection mechanism 7, a fastening sleeve no-go gauge inspection mechanism 8, a copper core feeding mechanism 9, a press-fitting mechanism 10, a scratch inspection mechanism 11, a spacing inspection mechanism 12, a copper core through hole inspection mechanism 13, and a receiving mechanism 14.

[0049] In actual use, when the floating fixture 4 rotates with the turntable 2 to correspond with the fastening sleeve feeding mechanism 5, the fastening sleeve feeding mechanism 5 places the fastening sleeve 001 in the floating fixture 4. Then, the floating fixture 4 rotates with the turntable 2 to correspond with the fastening sleeve size and through-hole detection mechanism 6, which detects the size and through-hole of the fastening sleeve 001. Then, the floating fixture 4 rotates with the turntable 2 to correspond with the fastening sleeve go gauge detection mechanism 7 and performs a go gauge 704 test. Then, the floating fixture 4 rotates with the turntable 2 to correspond with the fastening sleeve no-go gauge detection mechanism 8 and performs a no-go gauge 804 test. Then, the floating fixture 4 rotates with the turntable 2 to correspond with the copper core feeding mechanism 9, which places the copper core 002 in the fastening sleeve 001. Then, the floating fixture 4... Turntable 2 rotates to correspond with pressing mechanism 10. Pressing mechanism 10 rivets copper core 002 and fastening sleeve 001. Then, floating fixture 4 follows turntable 2 to rotate to correspond with scratch detection mechanism 11. Scratch detection mechanism 11 detects whether the upper end face of copper core 002 is scratched by pressing mechanism 10. Then, floating fixture 4 follows turntable 2 to rotate to correspond with spacing detection mechanism 12. Spacing detection mechanism 12 detects the distance between the upper end face of copper core 002 and the upper end face of fastening sleeve 001. Then, floating detection mechanism follows turntable 2 to move to correspond with copper core through hole detection mechanism 13. Copper core through hole detection mechanism 13 detects the diameter of through hole of copper core 002. Finally, floating fixture 4 follows turntable 2 to move to correspond with receiving mechanism 14. Receiving mechanism 14 transfers the product out of floating fixture 4.

[0050] In the above design, the fastening sleeve 001 is inspected by go gauge 704 and no-go gauge 804 before pressing. This can effectively complete the pressing of the copper core 002 and the fastening sleeve 001, and can also effectively detect whether the copper core 002 is qualified after pressing, thereby improving the product yield and saving production costs.

[0051] And specifically: such as Figure 2As shown, the fastening sleeve feeding mechanism 5 includes a first vibratory plate, a first linear vibrator 501 connected to the first vibratory plate, a first bracket 502 mounted on the frame 1, a first rotary cylinder 503 mounted on the first bracket 502 with its output end facing upward, a first plate 504 mounted on the output end of the first rotary cylinder 503, a second bracket 505 mounted on the frame 1, a first sliding cylinder 506 horizontally mounted on the second bracket 505, a second sliding cylinder 507 mounted on the first sliding cylinder 506, and a first rotary cylinder gripper 508 mounted on the output end of the second sliding cylinder 507. The first plate 504 has two centrally symmetrically arranged placement slots for placing fastening sleeves 001. The second bracket 505 has a channel for connecting the placement slots and the linear vibrator, and a first sensor 509 for detecting the orientation of the fastening sleeves 001 in the placement slots.

[0052] In actual use, the No. 1 vibratory plate vibrates the fastening sleeve 001 into the No. 1 straight vibrator 501 and then into one of the placement slots. The No. 1 sensor 509 detects the positive and negative positions of the fastening sleeve 001 in the placement slot. Then, the No. 1 rotary cylinder 503 drives the No. 1 plate 504 to rotate, so that the fastening sleeve 001 is gripped by the No. 1 rotary cylinder gripper 508. When the result detected by the No. 1 sensor 509 is that the position of the fastening sleeve 001 is reversed, the No. 1 rotary clamp rotates the fastening sleeve 001 180°. Otherwise, it does not rotate. Then, the fastening sleeve 001 is placed on the floating fixture 4.

[0053] The above design can effectively detect the front and back of the fastening sleeve 001, and after correcting the fastening sleeve 001 with the reversed position, it is placed on the floating fixture 4.

[0054] Specifically: such as Figure 3 As shown, the fastening sleeve size and through hole detection mechanism 6 includes a third bracket 61 mounted on the frame 1, a first camera 62 mounted on the third bracket 61 for detecting the fastening sleeve 001 from above, and a second camera 63 for detecting the fastening sleeve 001 from the side.

[0055] In actual use, the floating fixture 4 rotates with the turntable 2 to correspond to the size of the fastening sleeve and the through hole detection mechanism 6. Then, the first camera 62 detects whether the sleeve hole of the fastening sleeve 001 is open, and the second camera 63 detects the outer diameter of the fastening sleeve 001.

[0056] The above design enables the detection of the sleeve hole and outer circle of the fastening sleeve 001.

[0057] Specifically: such as Figure 4As shown, the fastening sleeve go gauge inspection mechanism 7 includes a fourth bracket 701 mounted on the frame 1, a third slide cylinder 702 mounted on the upper end of the fourth bracket 701, a first motor 703 mounted on the output end of the third slide cylinder 702, a go gauge 704 mounted on the output end of the first motor 703, a first guide rail 706 vertically mounted on the fourth bracket 701, a first sliding plate 707 slidably mounted on the first guide rail 706, and a go gauge 704 mounted on the fourth bracket 701. The central part includes a first cylinder 708 for driving the first sliding plate 707 to slide, a fourth sliding stage cylinder 709 fixedly mounted on the first sliding plate 707, and a fourth displacement sensor 710 for sensing the go gauge 704 located at the output end of the fourth sliding stage cylinder 709. The go gauge 704 is also fitted with a first spring. The first sliding plate 707 is provided with a first limiting plate 711, and the first limiting plate 711 is provided with a first hole that is slidably connected to the go gauge 704.

[0058] In actual use, cylinder 708 drives sliding plate 707 to move down, so that a limiting plate presses down on the product and the floating fixture 4 is pressed. Then, cylinder 702 drives motor 703 to move down. After the go gauge 704 extends into the fastening sleeve 001, motor 703 rotates to ensure that the go gauge 704 reaches the bottom. After the go gauge 704 reaches the bottom, displacement sensor 710 detects the depth of the go gauge 704 extending into the hole of the fastening sleeve 001.

[0059] The above design can effectively perform GO gauge 704 inspection on the fastening sleeve 001.

[0060] Specifically: such as Figure 5 As shown, the fastening sleeve stop gauge detection mechanism 8 includes a fifth bracket 801 mounted on the frame 1, a fifth slide cylinder 802 mounted on the upper end of the fifth bracket 801, a second motor 803 mounted on the output end of the fifth slide cylinder 802, a stop gauge 804 mounted on the output end of the second motor 803, a second guide rail 805 vertically mounted on the fifth bracket 801, a second sliding plate 806 slidably mounted on the second guide rail 805, a second limiting plate 808 fixedly mounted on the second sliding plate 806, and a second cylinder 807 fixedly mounted on the fifth bracket 801 for driving the second sliding plate 806 to slide. The second limiting plate 808 is provided with a through hole for the stop gauge 804 to pass through.

[0061] In actual use, cylinder 807 drives sliding plate 806 to move downward, causing limit plate 808 to press fastening sleeve 001, thus pressing floating fixture 4. Then, cylinder 802 drives motor 803 to align stop gauge 804 with the sleeve hole of fastening sleeve 001. If stop gauge 804 cannot be inserted into the sleeve hole after motor 803 drives stop gauge 804 to rotate, it means that stop gauge 804 has passed inspection.

[0062] The above design can effectively perform no-go gauge 804 inspection on the fastening sleeve 001.

[0063] Specifically: such as Figure 6 As shown, the copper core feeding mechanism 9 includes a second vibratory plate mounted on the frame 1, a second linear vibrator 901 connected to the second vibratory plate, a sixth bracket 902 mounted on the frame 1, a sixth slide cylinder 903 horizontally mounted on the sixth bracket 902, a seventh slide cylinder 904 fixedly mounted at the output end of the sixth slide cylinder 903, and a second rotary cylinder gripper 905 fixedly mounted at the output end of the seventh slide cylinder 904.

[0064] In actual use, the No. 2 vibratory feeder transports the copper core 002 to the No. 2 direct vibrator 901. Then, the No. 6 slide cylinder 903 drives the No. 7 slide cylinder 904 to move above the copper core 002. The No. 7 slide cylinder 904 drives the No. 2 rotary cylinder gripper 905 to move down and clamp the copper core 002. After that, the No. 7 slide cylinder 904 drives the No. 2 rotary cylinder gripper 905 to reset. The No. 6 slide cylinder 903 continues to drive the No. 7 slide cylinder 904 to move above the floating fixture 4. Then, the No. 7 slide cylinder 904 drives the No. 2 rotary cylinder gripper 905 to place the copper core 002 into the fastening sleeve 001.

[0065] In the above design, the copper core 002 can be effectively placed inside the fastening sleeve 001.

[0066] Specifically: such as Figures 7 to 11 As shown, the pressing mechanism 10 includes a seventh bracket 103 mounted on the frame 1 and a servo press 101 mounted on the seventh bracket 103. A contour pressing head 102 is mounted on the output end of the servo press 101. The bracket includes a base plate fixedly connected to the frame 1, a side plate mounted on the base plate, a top plate mounted on the side plate, and a flat plate 108 mounted on the side plate below the servo press 101. A third cylinder 104 is also mounted on the bracket. A guide rod 105 corresponding to the contour pressing head 102 is slidably mounted on the flat plate 108. A connecting rod 106 is hinged to the base plate. The two ends of the connecting rod 106 are respectively hinged to the output end of the third cylinder 104 and the lower end of the guide rod 105. A tapered hole 107 with an upward opening is provided at the upper end of the guide rod 105. The copper core 002 is located inside the tapered hole 107, and the fastening sleeve 001 is located outside the tapered hole 107.

[0067] In actual use, cylinder 104 drives one end of connecting rod 106 to move down, causing connecting rod 106 to drive guide rod 105 to move up. At this time, copper core 002 is located inside tapered hole 107, fastening sleeve 001 is located outside tapered hole 107, and then servo press 101 drives contour press head 102 to press down.

[0068] In the above design, the mechanism design and specific implementation of the pressing mechanism 10 can effectively ensure that the copper core 002 and the fastening sleeve 001 are correctly aligned during pressing, thereby improving the accuracy and efficiency of pressing.

[0069] Specifically: such as Figures 12 to 16 As shown, the scratch detection mechanism 11 includes an eighth bracket 110 mounted on the frame 1 and a third camera 111 mounted on the eighth bracket 110 for detecting the product from above. The spacing detection mechanism 12 includes a ninth bracket 121 mounted on the frame 1, an eighth slide cylinder 122 mounted on the ninth bracket 121, a mounting plate 123 mounted on the output end of the eighth slide cylinder 122, a first displacement sensor 124 mounted on the mounting plate 123, and a first displacement sensor 124 located on the first displacement sensor. The support plate 125 below the device 124 has a linear bearing 126 mounted on it. An abutment rod 127 is fitted inside the linear bearing 126. The abutment rod 127 has an annular protrusion for limiting its downward movement. The copper core through-hole detection mechanism 13 includes a No. 10 bracket 1301 mounted on the frame 1, a No. 9 slide cylinder 1302 mounted on the No. 10 bracket 1301, a connecting plate 1303 at the output end of the No. 9 slide cylinder 1302, and a mounting plate 1304. The fixed sleeve 1304 on 1303, the first positioning block 1305 and the second positioning block 1306 slidably disposed within the fixed sleeve 1304, the needle gauge 1309 sleeved within the first positioning block 1305 and the second positioning block 1306, the upper clamping block 1307 fixedly connected above the first positioning block 1305 and the needle gauge 1309, and the lower clamping block 1308 fixedly connected between the second positioning block 1306 and the needle gauge 1309, wherein the lower end of the first positioning block 1305 is provided with a first conical protrusion 131. 4. The lower end of the second positioning block 1306 is provided with a second conical protrusion 1315. The fixing sleeve 1304 is provided with a first conical groove that cooperates with the first conical protrusion 1314 and a second conical groove that cooperates with the second conical protrusion 1315. The first positioning block 1305 is fitted with a second spring 1311. The second positioning block 1306 is fitted with a third spring. The tenth bracket 1301 is also provided with a pressure relief valve 1313 for controlling the air pressure of the ninth slide cylinder 1302.

[0070] In actual use, after the floating fixture 4 moves with the turntable 2 to correspond with the scratch detection mechanism 11, the third camera 111 detects whether there are scratches on the upper surface of the copper core 002. After the floating fixture 4 moves with the turntable 2 to correspond with the spacing detection mechanism 12, the eighth slide cylinder 122 drives the mounting plate 123 to move down. At this time, the lower end of the abutment rod 127 abuts against the upper end of the copper core 002 and slides upward along the linear bearing 126 until the support plate 125 presses down on the product and the floating fixture 4 is pressed tight. The first displacement sensor 124 detects the distance that the abutment rod 127 moves upward. By subtracting the distance that the abutment rod 127 moves upward from the original distance that the abutment rod 127 extends beyond the lower end of the support plate 125, the distance between the upper end surface of the copper core 002 and the upper end surface of the fastening sleeve 001 can be obtained. After the floating fixture 4 moves with the turntable 2 to correspond with the copper core through hole detection mechanism 13, the ninth slide cylinder 1302 drives the connecting plate 1303 to move down, causing the needle gauge 1309 to move towards the through hole of the copper core 002. When the needle gauge 1309 can smoothly extend into the through hole of the copper core 002, the product is qualified. When the needle gauge 1309 cannot extend into the through hole of the copper core 002, the needle gauge 1309 drives the first positioning block 1305 and the second positioning block 1306 to move up through the upper clamping block 1307 and the lower clamping block 1308, compressing the second spring 1311 and the third spring 1312. The pressure relief valve 1313 releases pressure on the ninth slide cylinder 1302, and the product is unqualified at this time.

[0071] The above design effectively enables the inspection of the upper surface of the pressed copper core 002, the calculation of the distance between the upper surface of the pressed copper core 002 and the upper surface of the fastening sleeve 001, and the inspection of whether the diameter of the through hole of the copper core 002 meets the minimum requirements. Furthermore, the upper clamping block 1307 and the lower clamping block 1309 effectively clamp the needle gauge. Simultaneously, the engagement of the first conical protrusion 1314 and the first conical groove, and the engagement of the second conical protrusion 1315 and the second conical groove, reduces the possibility of vibration and damage to the needle gauge 1309 when encountering a defective copper core 002, and allows for rapid reset.

[0072] Specifically: such as Figure 17 As shown, the turntable 2 is equipped with defect recording fixtures 15 that correspond one-to-one with the fastening sleeve feeding mechanism 5, the fastening sleeve size and through hole detection mechanism 6, the fastening sleeve go gauge detection mechanism 7, the fastening sleeve no-go gauge detection mechanism 8, the copper core feeding mechanism 9, the pressing mechanism 10, the scratch detection mechanism 11, the spacing detection mechanism 12, and the copper core through hole detection mechanism 13.

[0073] In actual use, when the corresponding defect record tooling 15 detects that the product is unqualified, the subsequent workstations will stop working until the receiving mechanism 14 collects the unqualified product.

The first sensor 509 detects the positive and negative positions of the fastening sleeve 001 in the placement slot. Then, the first rotary cylinder 503 drives the first plate 504 to rotate, so that the fastening sleeve 001 is gripped by the first rotary cylinder claw 508. When the result detected by the first sensor 509 is that the position of the fastening sleeve 001 is reversed, the first rotary clamp rotates the fastening sleeve 001 180°. Otherwise, it does not rotate. Then, the fastening sleeve 001 is placed on the floating fixture 4.

[0076] S2, the floating fixture 4 rotates with the turntable 2 and corresponds to the fastening sleeve size and through hole detection mechanism 6. Then, the first camera 62 detects the sleeve hole diameter of the fastening sleeve 001, and the second camera 63 detects the outer diameter of the fastening sleeve 001.

[0077] S3. The floating fixture 4 rotates with the turntable 2 to correspond with the fastening sleeve gauge detection mechanism 7.

Then the third slide table drives the first motor 703 to move down. After the gauge 704 extends into the fastening sleeve 001, the first motor 703 rotates to ensure that the gauge 704 reaches the bottom. After the gauge 704 reaches the bottom, the fourth displacement sensor 710 detects the depth value of the gauge 704 extending into the sleeve hole of the fastening sleeve 001.

[0078] S4. The floating fixture 4 rotates with the turntable 2 to correspond with the fastening sleeve check gauge inspection mechanism 8. Under the premise that the fastening sleeve 001 is qualified after the fastening sleeve check gauge inspection mechanism 7 detects that the fastening sleeve 001 is qualified, the second cylinder 807 drives the second sliding plate 806 to press the fastening sleeve 001, so that the floating fixture 4 is pressed tight. Then, the fifth sliding cylinder 802 drives the second motor 803 to drive the check gauge 804 to align with the sleeve hole of the fastening sleeve 001. If the check gauge 804 cannot be inserted into the sleeve hole after the second motor 803 drives the check gauge 804 to rotate, it means that the check gauge 804 is qualified.

[0079] S5. The floating fixture 4 rotates with the turntable 2 to correspond with the copper core feeding mechanism 9. Under the premise that the stop gauge 804 inspection mechanism has passed the inspection, the second vibratory plate transports the copper core 002 to the second direct vibrator 901. Then, the sixth slide cylinder 903 drives the seventh slide cylinder 904 to move above the copper core 002. The seventh slide cylinder 904 drives the second rotary cylinder gripper 905 to move down and clamp the copper core 002. After that, the seventh slide cylinder 904 drives the second rotary cylinder gripper 905 to reset. The sixth slide cylinder 903 continues to drive the seventh slide cylinder 904 to move above the floating fixture 4. Then, the seventh slide cylinder 904 drives the second rotary cylinder gripper 905 to place the copper core 002 in the fastening sleeve 001.

[0080] S6. The floating fixture 4 rotates with the turntable 2 to correspond with the pressing mechanism 10. With the copper core 002 placed in the fastening sleeve 001, the third cylinder 104 drives one end of the connecting rod 106 to move down, so that the connecting rod 106 drives the guide rod 105 to move up. At this time, the copper core 002 is located in the conical hole 107 and the fastening sleeve 001 is located outside the conical hole 107. Then the servo press 101 drives the contour pressing head 102 to press down.

[0081] S7. After the copper core 002 and the fastening sleeve 001 are pressed together, the floating fixture 4 moves with the turntable 2 to correspond with the scratch detection mechanism 11, and the third camera 111 detects whether there are scratches on the upper surface of the copper core 002.

[0082] S8. After the scratch detection mechanism 11 passes the inspection, the floating fixture 4 moves with the turntable 2 to correspond with the spacing detection mechanism 12. Then, the No. 8 slide cylinder 122 drives the mounting plate 123 to move down. At this time, the lower end of the abutment rod 127 abuts against the upper end of the copper core 002 and slides upward along the linear bearing 126 until the support plate 125 presses down on the product and the floating fixture 4 is pressed tight. The No. 1 displacement sensor 124 detects the distance of the abutment rod 127 moving upward. The distance of the abutment rod 127 moving upward is obtained by subtracting the distance of the abutment rod 127 moving upward from the original distance of the abutment rod 127 extending out of the lower end of the support plate 125.

[0083] S9. After the floating fixture 4 moves with the turntable 2 to correspond with the copper core through hole detection mechanism 13, and the spacing detection mechanism 12 passes the test, the ninth slide cylinder 1302 drives the connecting plate 1303 to move down, causing the needle gauge 1309 to move towards the through hole of the copper core 002.
