[0003] With the development of technology, wheel hub bearings have now developed to the third generation. The first generation of wheel hub bearings is composed of two angular contact ball bearings spliced ​​together, which is difficult to maintain. In order to facilitate maintenance, the outer rings of the second and third generation wheel hub bearings are designed with flanges, and the bearings are fixed by the flanges, making maintenance more convenient.

DETAILED DESCRIPTION

[0039] Reference Figure 1 The flange 11 of the hub bolt has a mounting hole 13 on its disk surface, and the side wall of the cap has vertical grooves. The vertical groove end of the bolt 12 is inserted and fixed in the mounting hole. The vertical grooves are used to prevent rotation and facilitate the installation of the nut.

[0040] The following is combined with Figure 2 —18 provides further details of this application.

[0041] In the first aspect, the embodiment of the present application discloses a bearing bolt assembly device, referring to Figure 2 and Figure 4 It includes a frame 1 and a feeding mechanism 2, a detection mechanism 3, a supporting mechanism 4, a bolt inserting mechanism 5, a bolt supplying mechanism 6, and a bolt driving mechanism 7 arranged on the frame 1.

[0042] Reference Figure 4 and Figure 5The supporting mechanism 4 includes a first tray 41, a second tray 42, a third tray 43 and a transfer assembly 8. The first tray 41, the second tray 42 and the third tray 43 are arranged along the same straight line.

[0043] Reference Figure 6 、 Figure 7 and Figure 8 The first tray 41 includes a cylindrical base 411 rotatably mounted on the frame 1 and a plurality of sliders 412 horizontally slidably mounted on the base 411. The number of sliders 412 is determined according to the size and manufacturing material of the flange 11. The flange 11 processed in this embodiment is made of aluminum alloy, and the number of sliders 412 is three.

[0044] Reference Figure 6 、 Figure 7 and Figure 8 The rotation axis of the base 411 is vertical, and the sliders 412 are evenly distributed axially around the rotation circumference of the base 411. The sliders 412 slide radially along the base 411. A clamping block 413 is detachably mounted on the top wall of the slider 412 by bolts. The top view of the clamping block 413 is fan-shaped, and the cross-section of the clamping block 413 is L-shaped. When the flange 11 is placed on the first tray 41, the bottom wall of the flange 11 is placed in contact with the horizontal end of the clamping block 413. A tension spring 414 is provided between the end of the slider 412 facing the axis of the base 411 and the base 411. The two ends of the tension spring 414 are fixedly connected to the slider 412 and the base 411 respectively. When the flange 11 is placed on the clamping block 413, the slider 412, under the action of the tension spring 414, pushes the vertical end of the clamping block 413 to fit tightly against the lower end side wall of the flange 11.

[0045] Reference Figure 6 、 Figure 7 and Figure 8 A first motor is fixedly mounted on the frame 1 to drive the base 411 to rotate. The clamping blocks 413 clamp the flange 11 to the base 411. Different flange 11 models can be adapted by replacing the corresponding clamping blocks 413. When the clamping blocks 413 clamp the flange 11, a gap exists between them. This gap compensates for any shape errors of the clamping blocks 413 or the flange 11, improving the clamping stability of the clamping blocks 413.

[0046] Reference Figure 2 、 Figure 3 and Figure 7The feeding mechanism 2 includes a first mounting block 22, which is horizontally slidably mounted to the frame 1 via a rodless cylinder. The sliding direction of the first mounting block 22 is parallel to the arrangement direction of the first tray 41, the second tray 42, and the third tray 43. A first clamping jaw 23 is mounted on the first mounting block 22, which is vertically raised and lowered by the cylinder. The first clamping jaw 23 is a common pneumatic clamping jaw, and those skilled in the art can choose the one they want based on their actual needs.

[0047] Reference Figure 2 The feeding mechanism 2 also includes a loading conveyor belt 21 rotatably mounted on the frame 1. The loading conveyor belt 21 is connected to the previous process and is used to horizontally transport the flange 11 processed in the previous process to the first clamp 23. The loading conveyor belt 21 rotates along the arrangement direction of the first tray 41, the second tray 42 and the third tray 43.

[0048] Reference Figure 2 、 Figure 3 and Figure 7 The first jaw 23 is driven by the cylinder to rise, and the first jaw 23 corrects the position of the flange 11 through the clamping plate 10, and drives the flange 11 to rise and leave the feeding conveyor 21 through the baffle 64.

[0049] Reference Figure 2 、 Figure 3 and Figure 7 The first mounting block 22 can be driven by the rodless cylinder to slide to the top of the first tray 41. At this time, the first clamping jaw 23 is driven by the cylinder to drop and insert the flange 11 into the middle of the three clamping blocks 413. Then the first clamping jaw 23 releases the flange 11 and resets it, completing the loading of the flange 11.

[0050] Reference Figure 4 、 Figure 5 and Figure 7The detection mechanism 3 includes a mounting ring 31, which is fixedly mounted on the frame 1 and coaxial with the base 411. The mounting ring 31 is located below the first tray 41. The mounting ring 31 is coaxially provided with an arc groove 311. A second mounting block 32 is slidably mounted in the arc groove 311. A third mounting block 33 is slidably mounted on the second mounting block 32. The third mounting block 33 slides radially along the mounting ring 31.

[0051] Reference Figure 9 and Figure 10 The third mounting block 33 is fixedly mounted with a first photoelectric sensor 34. When the first tray 41 drives the flange 11 to rotate to the correct position and the mounting holes 13 of the flange 11 are located at the specified position—that is, the position of one of the mounting holes 13 of the flange 11 corresponds to the bolt insertion mechanism 5, the first photoelectric sensor 34 is used to detect the position of one of the mounting holes 13 of the flange 11, and the position of the mounting hole 13 of the flange 11 is corrected through the cooperation between the first photoelectric sensor 34 and the first tray 41.

[0052] At the same time, for different types of hub bearing flanges 11, the position of the first photoelectric sensor 34 can be adjusted to the corresponding detection position by sliding the second mounting block 32 and the third mounting block 33, which is convenient to adjust and has high adaptability.

[0053] Reference Figure 9 and Figure 10 The second mounting block 32 is rotatably mounted with an adjusting gear 321, and one side edge of the arc-shaped slot 311 is integrally provided with an adjusting gear tooth 312. The adjusting gear tooth 312 is arranged along the side edge of the arc-shaped slot 311, and the adjusting gear 321 is engaged with the adjusting gear tooth 312. The second mounting block 32 is fixedly mounted with an adjusting motor 322, and the output shaft of the adjusting motor 322 is coaxially fixedly connected to the adjusting gear 321. The adjusting motor 322 drives the adjusting gear 321 to rotate, thereby driving the second mounting block 32 to slide.

[0054] The second mounting block 32 is rotatably mounted with a first adjusting screw 323, which passes through the third mounting block 33 and is threadedly engaged with the third mounting block 33. The third mounting block 33 is driven to slide by rotating the first adjusting screw 323, and the third mounting block 33 is self-locked by the first adjusting screw 323.

[0055] Reference Figure 9 and Figure 10 The end of the first adjusting screw rod 323 is located in the second mounting block 32, and a hexagonal hole is coaxially provided at its end. When rotating, it needs to be rotated by an hexagonal wrench, which further reduces the probability of the first adjusting screw rod 323 being interfered with by the outside world.

[0056] The second mounting block 32 and the third mounting block 33 are both threadedly mounted with bolts for fixing. After the positions of the second mounting block 32 and the third mounting block 33 are adjusted, the bolts need to be tightened to fix the second mounting block 32 and the third mounting block 33, so that the positions of the second mounting block 32 and the third mounting block 33 are not easily changed due to external reasons during operation.

[0057] Reference Figure 4 and Figure 5 The frame 1 is fixedly mounted with a second motor, the output shaft of the second motor is vertical, and the second tray 42 is detachably mounted on the output shaft of the second motor by bolts.

[0058] Reference Figure 6 and Figure 11 The frame 1 is slidably mounted with an eighth mounting block 35, and the eighth mounting block 35 is fixedly mounted with a second photoelectric sensor 36. The eighth mounting block 35 slides radially along the axis of the second tray 42. When the flange 11 of the second tray 42 is inserted with a bolt through the bolt insertion mechanism 5, the detection light beam of the second photoelectric sensor 36 coaxially passes through one of the mounting holes 13 of the flange 11.

[0059] Reference Figure 6 、 Figure 11 and Figure 13 The second photoelectric sensor 36 is located below the bolts inserted into the flange 11 of the second tray 42. Since the distance between the lower end of the bolt and the second photoelectric sensor 36 is smaller than the distance between the flange 11 and the second photoelectric sensor 36, the second photoelectric sensor 36 can detect whether there are bolts by the difference in reflected light, and then count the bolts on the flange 11.

[0060] For different types of flanges 11, since only counting is required, the adjustment can be completed by sliding the eighth mounting block 35 so that the detection beam of the second photoelectric sensor 36 coaxially passes through the circle where the center of the mounting hole 13 of the flange 11 is located, which is relatively convenient.

[0061] A second adjusting screw 351 is rotatably mounted on the frame 1. The second adjusting screw 351 passes through the eighth mounting block 35 and engages with the eighth mounting block 35. Rotating the second adjusting screw 351 causes the eighth mounting block 35 to slide, while also self-locking the eighth mounting block 35. A bolt for securing the eighth mounting block 35 is also threadedly mounted on the eighth mounting block 35. After the position of the second photoelectric sensor 36 is adjusted, the bolt is tightened to secure the eighth mounting block 35, preventing it from slipping due to external factors.

[0062] Reference Figure 3 、 Figure 5 、 Figure 15 and Figure 16The transfer assembly 8 includes a lifting plate 81 that is installed horizontally on the frame 1 and slides upward, a first translation frame 82 that is installed horizontally on the lifting plate 81 and slides horizontally, and a second translation frame 83 that is installed horizontally on the first translation frame 82.

[0063] The lifting plate 81 , the first translation frame 82 and the second translation frame 83 are all horizontal and rectangular. The length direction of the lifting plate 81 is parallel to the rotation direction of the feeding conveyor belt 21 .

[0064] The lifting plate 81, the first translation frame 82, and the second translation frame 83 are all driven to slide by hydraulic cylinders. The first translation frame 82 slides along the width direction of the loading conveyor 21 and can slide close to the first pallet 41, the second pallet 42, and the third pallet 43. The second translation frame 83 slides along the length direction of the first translation frame 82.

[0065] At least eight mounting plates 84 are slidably mounted on the top wall of the second translation frame 83 along its length direction. The number of mounting plates 84 is an even number, and the specific number is determined according to subsequent processes. In this embodiment, since only discharging is required, eight plates are used.

[0066] The odd-numbered mounting plates 84 are fixedly connected by connecting rods 841, and the even-numbered mounting plates 84 are fixedly connected by connecting rods 841. A clamping cylinder 86 is fixedly mounted on the second translation frame 83. The piston rod of the clamping cylinder 86 is fixedly connected to one of the mounting plates 84. The clamping cylinder 86 drives the mounting plate 84 to slide, thereby sliding through the odd-numbered or even-numbered mounting plates 84.

[0067] Two adjacent mounting plates 84 located in the middle of the second translation frame 83 are each fixed with a rack 842. A connecting gear 85 is rotatably mounted on the second translation frame 83. The two racks 842 are located on either side of the connecting gear 85 and mesh with the connecting gear 85. When an odd-numbered or even-numbered mounting plate 84 slides, the cooperation between the racks 842 and the connecting gear 85 drives the remaining mounting plates 84 to slide toward or away from each other.

[0068] The mounting plate 84 is fixedly installed with a mounting rod 87, and the mounting rod 87 can also be detachably installed with a clamping plate 10 through bolts. The mounting rod 87 extends toward the first pallet 41, the second pallet 42 and the third pallet 43. When the mounting plate 84 slides relatively, the mounting plate 84 can clamp the fixed flange 11 through the clamping plate 10.

[0069] When the position of the flange 11 in the first pallet 41 is adjusted, the first translation frame 82 slides toward the first pallet 41 under the push of the hydraulic cylinder. After the first translation frame 82 slides to the specified position, the clamping cylinder 86 starts to drive the mounting plate 84 to slide, and then drives the clamping plate 10 to clamp and fix the flange 11. Then the lifting plate 81 rises under the drive of the hydraulic cylinder, and pulls the flange 11 out of the first pallet 41. Then the second translation frame 83 slides under the drive of the hydraulic cylinder, and drives the flange 11 to the top of the second pallet 42. The lifting plate 81 descends under the drive of the hydraulic cylinder and inserts the flange 11 into the second pallet 42. Then the clamping cylinder 86 resets to release the flange 11. Then the first translation frame 82 resets, and then the second translation frame 83 resets to complete the transportation of the flange 11.

[0070] Reference Figure 3 、 Figure 5 and Figure 11 The bolt insertion mechanism 5 comprises a fourth mounting block 51 slidably mounted on the frame 1 and a fifth mounting block 52 slidably mounted on the fourth mounting block 51. Both the fourth mounting block 51 and the fifth mounting block 52 are driven by pneumatic cylinders. A second clamping jaw 53 is fixedly mounted on the fifth mounting block 52. This second clamping jaw 53 is a common pneumatic clamp, which can be selected by those skilled in the art based on specific circumstances. The second clamping jaw 53 is used to clamp the fixing bolt.

[0071] Reference Figure 11 - Figure 14 The bolt supply mechanism 6 includes a vibrating plate 61 fixedly mounted to the ground on one side of the bolt insertion mechanism 5. The discharge end of the discharge track of the vibrating plate 61 is fixedly mounted to the frame 1. Two vertical reversing plates 62 are slidably mounted on the frame 1 at the discharge end of the discharge track. The two reversing plates 62 are parallel to each other and slide toward or away from each other. A bidirectional screw rod 622 is rotatably mounted on the frame 1. The two ends of the bidirectional screw rod 622 pass through the two reversing plates 62 and are threadedly engaged with the reversing plates 62. Rotation of the bidirectional screw rod 622 drives the two reversing plates 62 to slide toward or away from each other.

[0072] One end of the reversing plate 62 is connected to the discharge end of the vibrating disk 61. Chamfers 621 are provided on opposite sides of the top walls of the two reversing plates 62. The distance between the two reversing plates 62 is greater than the bolt body diameter and smaller than the bolt cap diameter. The distance between the upper sides of the two chamfers 621 is greater than the bolt cap diameter.

[0073] When the bolt output by the vibration disk 61 enters between the two reversing plates 62, under the action of gravity, the bolt body will enter between the two reversing plates 62, and the bolt cap will be stuck on the chamfered surface 621 of the reversing plate 62, so that the bolt is suspended between the two reversing plates 62.

[0074] The frame 1 is also fixedly mounted with two material storage plates 63, which are parallel to each other. A horizontal baffle 64 is fixedly mounted on the upper side of the opposite side of the two material storage plates 63. The spacing between the two baffles 64 is smaller than the bolt cap diameter and larger than the bolt body diameter. One end of the material storage plate 63 is connected to one end of the reversing plate 62. The bolts in the reversing plate 62 are pushed into the material storage plate 63 and hung on the two baffles 64 for storage during the process of continuous output of bolts by the vibrating disk 61.

[0075] The reversing plate 62 and the material storage plate 63 are parallel to each other, and the reversing plate 62 is parallel to the transport direction of the loading conveyor belt 21, so as to save the installation space in the width direction of the entire device.

[0076] Reference Figure 11 - Figure 14 The bolt supply mechanism 6 also includes a conveying device 9, which includes a mounting seat 91 fixedly mounted on the frame 1, a feeding rod 92 slidably mounted on the mounting seat 91, a feeding block 93 slidably mounted on the frame 1, and a feeding claw 94 fixedly mounted on the feeding block 93, and the feeding claw 94 is used to clamp the fixing bolts.

[0077] One side of the mounting seat 91 is connected to the end of the material storage plate 63 facing away from the reversing plate 62. A storage bin 912 is provided on the side where the mounting seat 91 is connected to the material storage plate 63. The bolts between the material storage plates 63 slide into the material storage bin under the push of the vibration disk 61. The cross-section of the material storage bin is T-shaped, and the bolts are temporarily suspended in the material storage bin.

[0078] A accommodating cavity 911 is also provided in the mounting seat 91, and the feed rod 92 is horizontal. A slot 921 is provided on the bottom wall of the feed rod 92, and the two ends of the slot 921 respectively penetrate the two side walls of the feed rod 92. The slot width of the slot 921 is smaller than the width inside the slot 921. The width of the slot 921 is larger than the diameter of the bolt body but smaller than the diameter of the bolt cap. The bolt cap can be slidably clamped in the slot 921, thereby hanging the bolt on the feed rod 92.

[0079] The accommodating chamber 911 is connected to the storage bin. In the initial state, the discharge end of the storage bin corresponds to the card slot 921. The bolts in the storage bin can slide into the accommodating chamber 911 and be hung in the card slot 921 under the push of the vibration plate 61.

[0080] The feeding rod 92 slides along the width direction of the conveyor belt. The feeding rod 92 is driven by a cylinder. The accommodating cavity 911 penetrates the side wall of the mounting seat 91. When the feeding rod 92 slides, the bolt can be taken out of the accommodating cavity 911.

[0081] A detection slot 922 is provided on the top wall of the feed rod 92. The detection slot 922 is arranged along the length of the feed rod 92. One end of the detection slot 922 is connected to the clamping slot 921. A third photoelectric sensor 95 is fixedly mounted on the top wall of the mounting base 91. The detection end of the third photoelectric sensor 95 is located in the detection slot 922. The third photoelectric sensor 95 detects whether there is a bolt in the clamping slot 921. Since the detection end of the third photoelectric sensor 95 is located in the clamping slot 921, the detection signal of the third photoelectric sensor 95 is not easily interfered with by the complex surrounding environment. At the same time, when the feed rod 92 slides, the detection slot 922 accommodates the third photoelectric sensor 95, so that the third photoelectric sensor 95 and the feed rod 92 do not interfere with each other.

[0082] The side wall of the feeding rod 92 fits into the side wall of the accommodating chamber 911. When the third photoelectric sensor 95 detects a bolt in the slot 921, the cylinder starts to push the feeding rod 92 out of the mounting seat 91. At this time, the bolt is not completely located in the accommodating chamber 911, and the part of the bolt located in the accommodating chamber 911 is larger than the part of the bolt located in the storage bin 912. When the feeding rod 92 extends from the mounting seat 91, the bolt can be completely inserted into the accommodating chamber under the push of the side wall of the accommodating chamber, so that the bolts corresponding to different types of flanges 11 can be taken out of the storage bin 912 relatively smoothly, and there is no need to adjust the depth of the accommodating chamber 911 and the width of the feeding rod 92 to adapt to the bolt cap diameter of different types of bolts.

[0083] Furthermore, by taking out the bolts in the above-mentioned manner, the latter bolt will not interfere with the sliding of the feeding rod 92 when being taken out.

[0084] The feed block 93 slides horizontally along the transport direction of the loading conveyor 21. The feed block 93 is also driven by a pneumatic cylinder. When the cylinder extends, the feed block 93 slides below the feed rod 92. At this time, the cylinder drives the feed rod 92 to extend, and the feed rod 92 drives the bolt to move between the pick-up claws 94. The pick-up claws 94 use pneumatic clamps. When the bolt is located between the pick-up claws 94, the pick-up claws 94 activate and clamp the bolt. The feed block 93 then resets and removes the bolt from the clamping slot 921. After the feed block 93 is reset, the bolt is located directly below the second clamping jaw 53.

[0085] The fourth mounting block 51 and the fifth mounting block 52 both use the cylinder as a sliding drive source. When the feeding block 93 is reset, the fifth mounting block 52 descends under the drive of the cylinder, driving the second clamping jaw 53 to descend, and then the second clamping jaw 53 clamps and fixes the upper end of the bolt, and the picking claw 94 is released and reset. The fifth mounting block 52 rises and resets under the drive of the cylinder to remove the bolt from the picking claw 94.

[0086] The fourth mounting block 51 slides horizontally along the width direction of the feeding conveyor belt 21. When the second clamping jaw 53 takes out the bolt, the cylinder starts to push the fourth mounting block 51 to slide. The fourth mounting block 51 can slide to the second clamping jaw 53 above the flange 11 on the second pallet 42. At this time, the bolt clamped by the second clamping jaw 53 is facing the corresponding mounting hole 13 on the flange 11, and then the fifth mounting block 52 descends to drive the second clamping jaw 53 to insert the bolt into the mounting hole 13 of the flange 11, completing the insertion of the bolt.

[0087] The driving cylinder of the fourth mounting block 51 is a cylinder with adjustable stroke so as to adjust the sliding stroke of the fourth mounting block 51 and thus adapt to different flanges 11 .

[0088] Reference Figure 2 、 Figure 4 、 Figure 17 and Figure 18 A seventh mounting block 73 is horizontally slidably mounted on the frame 1. The sliding direction of the seventh mounting block 73 is perpendicular to the conveying direction of the loading conveyor 21. A stroke-adjustable cylinder is fixedly mounted on the frame 1 to drive the sliding movement of the seventh mounting block 73. The third motor is fixedly mounted on the seventh mounting block 73. A buffer seat 74 is also fixedly mounted on the seventh mounting block 73. A support rod 75 is coaxially slidably mounted on the buffer seat 74. The support rod 75 is rotatably engaged with the buffer seat 74. One end of the support rod 75 is coaxially slidably connected to the output shaft of the third motor and is circumferentially fixed.

[0089] The support rod 75 and the buffer seat 74 are rotatably connected through a bearing. The support rod 75 is provided with a buffer spring 76. The two ends of the buffer spring 76 are respectively pressed against the end surface of the bearing and one end of the support rod 75. The third tray 43 is coaxially and detachably mounted on the top wall of the support rod 75 by bolts.

[0090] After the bolts on the flange 11 are inserted, the transfer assembly 8 transports the flange 11 to the third pallet 43 in the same way as above and inserts it. The disk surface of the flange 11 fits against the top wall of the third pallet 43. The third pallet 43 is provided with avoidance holes 431 corresponding one-to-one to the bolts on the flange 11, and the bolts are inserted one-to-one into the avoidance holes 431.

[0091] The bolt driving mechanism 7 includes a sixth mounting block 71 that is installed on the frame 1 in a lifting and sliding manner. The sixth mounting block 71 is driven by a hydraulic cylinder. A cylindrical striking block 72 is fixedly installed on the bottom wall of the sixth mounting block 71. When the flange 11 is placed, the cylinder is started to drive the seventh mounting block 73 to slide to the bottom of the striking block 72. At this time, one of the bolts on the flange 11 is located directly below the striking block 72. The hydraulic cylinder is started to drive the sixth mounting block 71 and the striking block 72 to descend and nail the bolt into the flange 11. The impact of the striking block 72 on the flange 11 is absorbed by the buffer spring 76 to avoid damage to the motor caused by excessive impact.

[0092] After the nailing is completed, the seventh mounting block 73 is reset under the drive of the cylinder, and the transfer assembly 8 takes the flange 11 out of the third tray 43 and outputs it in the above manner.

[0093] When replacing a flange 11 of a different model for assembly, first adjust the sliding distance of the first mounting block 22 according to the parameters of the flange 11, replace the clamping block 413, the second tray 42, the third tray 43 and the clamping plate 10 according to the parameters of the flange 11, and adjust the sliding distance of the fourth mounting block 51 and the sliding distance of the seventh mounting block 73 according to the parameters of the flange 11.

[0094] Since the bolts are vertically inserted into the flange 11 , the fifth mounting block 52 does not need to be adjusted. Due to the support of the buffer spring 76 , the buffer spring 76 can compensate for the difference between the bolt sizes, so the sixth mounting block 71 does not need to be adjusted.

[0095] A horizontal limit plate 65 is provided on the upper side of the material storage plate 63, and the limit plate 65 is arranged along the length direction of the material storage plate 63. A number of screws are threadedly installed on the limit plate 65, one end of the screw passes through one of the material storage plates 63 and vertically slides with the material storage plate 63. A nut is threadedly installed on one end of the screw located on one side of the material storage plate 63, and a regular hexagonal clamping block is coaxially integrated with the other end of the screw located on the other side of the material storage plate 63. The limit plate 65 is fixed to the material storage plate 63 by the cooperation between the clamping block and the nut.

[0096] A gap is provided between the bottom wall of the limit plate 65 and the top wall of the bolts between the storage plate 63. This limit plate 65 limits the bolt's movement to prevent overlap during movement. A proximity sensor is installed on the bottom wall of the end of the limit plate 65 that faces the reversing plate 62. This proximity sensor detects the distance between the bolts and the limit plate 65.

[0097] Before the vibration plate 61 supplies bolts, first hang a bolt between the storage plates 63, and the bolt cap part is located between the two reversing plates 62, and then rotate the bidirectional screw rod 622 to drive the two reversing plates 62 to move relative to each other until the bolt is just lifted by the reversing plate 62 and the proximity sensor detects a change in the distance data of the bolt. The adjustment of the reversing plate 62 can be completed, so that the bolt in the reversing plate 62 slides between the storage plates 63 without getting stuck, and the adjustment is relatively simple and quick.

[0098] After all the above adjustments are complete, the positions of the first and second photosensors 34, 36 must be adjusted. Since only counting is required, the second photosensor 36 can be adjusted by simply radially sliding the second photosensor 36 for different flange models and numbers of mounting holes 13. Furthermore, knowing the diameters of the mounting holes 13 of different flanges 11 and the distances between the center points of the mounting holes 13 and the axis of the flange 11, the required adjustment distance can be calculated.

[0099] After adjusting the radial position, the first photoelectric sensor 34 also needs to adjust its circumferential position. First, it is roughly adjusted manually to slide the second mounting block 32 to the appropriate position, and then a flange 11 is placed on the first pallet 41. After the position of the flange 11 is corrected by the first photoelectric sensor 34 at this time, the flange 11 is transferred to the second pallet 42 by the transfer component 8 and then placed down. The flange 11 with adjusted position on the first pallet 41 is transported to the second pallet 42 by the transfer mechanism, and then the interval angle of the two adjacent mounting holes 13 of the flange 11 is rotated. The error of the circumferential position of the first photoelectric sensor 34 can be obtained by comparing the actual light transmission time and the theoretical light transmission time of the second photoelectric sensor 36. At the same time, the rotation direction of the second mounting block 32 when the angle needs to be adjusted can be obtained by whether the rotation angle of the second pallet 42 is larger or smaller than the theoretical rotation angle when the second photoelectric sensor 36 transmits light for the first time.

[0100] At this time, the adjustment motor 322 is started to complete the fine adjustment of the second mounting block 32 according to the test data.
