[0040] The embodiments of the present invention are further described below in conjunction with the accompanying drawings:

[0041] like Figure 2-3 As shown, a coupling assembly machine includes a machine base 1, on which a rotary feeding device 2 is provided, on which a plurality of positioning carriers 3 are evenly distributed along the circumference of the center are provided, and on the machine base 1, a connecting shaft assembling device 4, a positioning fixture closing device 5, a connecting block assembling device 6, a connecting sleeve assembling device 7, a long axis guiding device 13, a long axis assembling device 8, a short axis guiding device 14, a short axis assembling device 9, a riveting device 10, a positioning fixture opening device 11, and a feeding device 12 are sequentially provided along the center of the rotary feeding device 2.

[0042] like Figure 4 As shown, the rotary feeding device 2 includes a cam divider 21, the input end of the cam divider 21 is connected to a stepper motor 22, and the output end of the cam divider 21 is connected to a turntable 23. The stepper motor 22 can drive the turntable 23 through the cam divider 21 to achieve precise horizontal rotation.

[0043] The turntable 23 is provided with 12 positioning carriers 3 evenly arranged in the circumferential direction, and the positioning carriers 3 are fixedly installed at positions close to the edge of the turntable 23 .

[0044] like Figure 5-7 As shown, the positioning carrier 3 includes a carrier, on which a first positioning groove 31 adapted to the connecting shaft and a second positioning groove 32 adapted to the connecting sleeve are formed, a positioning fixture capable of clamping the connecting block is provided between the first positioning groove 31 and the second positioning groove 32, a first positioning hole 35 is formed on the middle side wall of the carrier, and a second positioning hole 36 is formed on the bottom of the carrier.

[0045] Among them, the positioning clamp includes a first clamping plate 33 arranged at the first positioning groove 31, and a second clamping plate 34 arranged at the second positioning groove 32. The first clamping plate 33 is hinged to the carrier, and the first clamping plate 33 is connected to an elastic member that drives it to rotate toward the second clamping plate 34, so as to realize elastic clamping of the connecting block. The second clamping plate 34 is slidably matched with the carrier, and the positioning clamp has a closed first position and an open second position.

[0046] When the coupling is assembled using the positioning carrier 3, the positioning fixture is first placed in the closed first position, the connecting shaft 1a is positioned and matched with the first positioning groove 31, the connecting sleeve 2a is positioned and matched with the second positioning groove 32, and the connecting block 3a is positioned and matched with the positioning fixture, so that the connecting shaft 1a, the connecting sleeve 2a, and the connecting block 3a can be accurately aligned with each other, and the long axis can connect the connecting shaft 1a and the connecting block 3a after passing through the first positioning hole 35, and a short axis passes through the second positioning hole 36 from bottom to top to connect the connecting sleeve 2a and the connecting block 3a, and the other short axis directly connects the connecting sleeve 2a and the connecting block 3a from top to bottom, thereby forming an integral structure. When the coupling is assembled, the second clamping plate 34 is slid so that the positioning fixture is in the open second position, and the assembled coupling can be directly taken out from the positioning carrier 3.

[0047] Furthermore, magnets 37 are provided at the bottom of the first positioning groove 31 and the second positioning groove 32. When the connecting shaft 1a and the connecting sleeve 2a are placed on the first positioning groove 31 and the second positioning groove 32, the magnet 37 can produce magnetic attraction to the connecting shaft 1a and the connecting sleeve 2a, thereby ensuring that the connecting shaft 1a and the connecting sleeve 2a will not move easily, ensuring the stable position, and improving the success rate of subsequent assembly.

[0048] A marble hole is also formed on the side wall of the second positioning hole 36, and a marble assembly 38 is arranged in the marble hole. The marble assembly includes a marble and a spring. Driven by the spring, the marble partially protrudes into the second positioning hole 36. Before the short shaft below is completely riveted, the marble can reliably block and limit the short shaft, effectively avoiding the problem of the short shaft falling and improving the success rate of assembly.

[0049] like Figure 8-9 As shown, the connecting shaft assembly device 4 includes a connecting shaft feeding mechanism 41, a connecting shaft feeding track 42, a connecting shaft in-place detection mechanism 43, and a connecting shaft assembly mechanism 44, which are used for feeding and assembling the connecting shaft.

[0050] The connecting shaft feeding mechanism 41 adopts but is not limited to a vibration plate, which is used for automatic sorting and feeding of the connecting shafts.

[0051] The connecting shaft feeding track 42 is installed on the machine base 1 , and one end of the connecting shaft feeding track 42 is connected to the connecting shaft feeding mechanism 41 and matched with the connecting shaft. The connecting shaft provided by the connecting shaft feeding mechanism 41 can be sorted and transported along the connecting shaft feeding track 42 .

[0052] The connecting shaft in-place detection mechanism 43 is arranged at the end of the connecting shaft feeding track 42, and is used to receive the connecting shaft and realize in-place detection through a proximity switch, so as to sense whether the connecting shaft is delivered in place.

[0053] The connecting shaft assembly mechanism 44 includes a first moving component 441, a first clamping component 442, and a first positioning plate 443. The first moving component 441 adopts two sets of linear drive modules driven by cylinders, which can realize movement in two directions of lifting and translation. The first clamping component 442 and the first positioning plate 443 are installed on the first moving component 441, and can move synchronously with the first moving component 441. The first clamping component 442 adopts a pneumatic clamp for clamping the connecting shaft, and the first positioning plate 443 can press the connecting shaft when the first clamping component 442 grabs or assembles the connecting shaft, so as to ensure that the position of the connecting shaft is accurate and stable, thereby improving the success rate of assembly.

[0054] During operation, the connecting shaft is continuously fed by the connecting shaft feeding mechanism 41 and continuously fed along the connecting shaft feeding track 42. When the connecting shaft reaches the connecting shaft in-place detection mechanism 43 and touches the proximity switch, it is clamped by the first clamping component 442, and then the first moving component 441 drives the first clamping component 442 to move toward the positioning carrier and accurately places the connecting shaft in the first positioning groove of the positioning carrier.

[0055] like Fig.10 As shown, the closing device 5 includes a closing transverse push plate 51 and a first pushing cylinder 52 for driving the closing transverse push plate 51 to move in translation. The closing transverse push plate 51 corresponds to the second clamping plate of the positioning carrier. The first pushing cylinder 52 can drive the closing transverse push plate 51 to move, and the closing transverse push plate 51 can push the second clamping plate to move, so that the positioning fixture comes to the first closed position.

[0056] Among them, a short shaft removal device 15 is also provided on the closing device 5, and the short shaft removal device 15 includes a first push rod 151 and a second push cylinder 152 that can drive the first push rod 151 to move up and down, and the first push rod 151 corresponds to the second positioning hole of the positioning carrier. In the process of automatic assembly of the coupling, it is inevitable that defective products due to assembly failure will appear. The short shaft at the lower end will remain in the second positioning hole if it is not riveted. Therefore, when assembling the coupling, it is necessary to remove the short shaft remaining in the second positioning hole. When the short shaft removal device 15 is working, the second push cylinder 152 pushes the first push rod 151 downward, and the first push rod 151 extends into the second positioning hole to push out the remaining short shaft, so as to ensure the normal assembly operation of the subsequent coupling.

[0057] Of course, the closing device 5 and the short-axis removing device 15 can also be respectively arranged at two workstations, while arranging the two at the same workstation and sharing a vertical plate makes the layout more reasonable and reduces the cost.

[0058] like Figure 11-13As shown, the connecting block assembly device 6 includes a connecting block feeding mechanism 61, a connecting block feeding track 62, a connecting block in-place detection mechanism 63, a connecting block pushing mechanism 64, and a connecting block assembly mechanism 65, which are used for feeding and assembling the connecting blocks.

[0059] The connecting block feeding mechanism 61 adopts but is not limited to a vibration plate, which is used for automatic sorting and feeding of connecting blocks.

[0060] The connecting block feeding track 62 is installed on the machine base 1 , and one end of the connecting block feeding track 62 is connected to the connecting block feeding mechanism 61 and matched with the connecting block. The connecting blocks provided by the connecting block feeding mechanism 61 can be transported in sequence along the connecting block feeding track 62 .

[0061] The connection block in-place detection mechanism 63 is arranged at the end of the connection block feeding track 62, and is used to receive the connection block and realize in-place detection through a proximity switch, and inductively detect whether the connection block is delivered in place.

[0062] The connecting block pushing mechanism 64 is arranged below the connecting block in-position detection mechanism 63, and comprises a first push rod 641 and a third push cylinder 642 for driving the first push rod 641 to move up and down, and is used to push the connecting block upward. The first push rod 641 is provided with a first return spring 643 on its outer sleeve, and after the first push rod 641 pushes the connecting block out, the first push rod 641 can be quickly reset under the action of the first return spring 643.

[0063] The connecting block assembly mechanism 65 includes a second moving assembly 651 and a second clamping assembly. The second moving assembly 651 uses two sets of linear drive modules driven by cylinders to achieve movement in two directions of lifting and translation.

[0064] The second clamping assembly includes a material picking mounting plate 652, which is mounted on the second moving assembly 651. A material picking core 653 is mounted on the material picking mounting plate 652. The material picking core 653 is formed with a material picking groove 6531 with an opening at the lower end and adapted to the connecting block. A fourth pushing cylinder 655 is also mounted on the material picking mounting plate 652. The fourth pushing cylinder 655 is driven and connected to a second push rod 656, and the lower end of the second push rod 656 can pass downward through the material picking core 653.

[0065] The second push rod 656 is provided with a second return spring 657 on its outer sleeve. After the second push rod 656 pushes the connecting block out, the second push rod 656 can be quickly returned to its original position under the action of the second return spring 657 .

[0066] Furthermore, an annular magnet 654 is installed in the material taking trough 6531 . When the connecting block is pushed into the material taking trough 6531 , the connecting block is adsorbed by the annular magnet 654 to ensure that the connecting block does not fall out of the material taking trough 6531 .

[0067] Furthermore, each side wall of the material taking trough 6531 is formed with a notch groove 6532. When the connecting block is pushed into the material taking trough 6531, it is conducive to the material taking trough 6531 to slightly deform to adapt to the connecting block, which can ensure the clamping of the connecting block and the accurate positioning of the connecting block.

[0068] During operation, the connection block is continuously fed by the connection block feeding mechanism 61 and continuously fed along the connection block feeding track 62. When the connection block reaches the connection block in-place detection mechanism 63 and touches the proximity switch, the second moving assembly 651 is first actuated to drive the material taking mounting plate 652 to act synchronously, so that the material taking core 653 on the material taking mounting plate 652 moves to above the connection block in-place detection mechanism 63, and the material taking slot 6531 of the material taking core 653 corresponds to the connection block. Then, the third pushing cylinder 642 pushes the first push rod 641 to move the connection block. It is pushed upward into the material taking trough 6531, and then the first push rod 641 is reset, and at the same time the second moving assembly 651 is actuated, and drives the material taking mounting plate 652 to move synchronously, so that the material taking core 653 on the material taking mounting plate 652 moves to above the positioning carrier, and the material taking trough 6531 of the material taking core 653 corresponds to the positioning fixture, and finally the fourth pushing cylinder 655 pushes the second push rod 656 downward to push the connecting block in the material taking trough 6531 downward to the positioning fixture, and is clamped and fixed by the positioning fixture, thereby completing the connecting block feeding assembly.

[0069] like Figure 14-15 As shown, the connecting sleeve assembly device 7 includes a connecting sleeve feeding mechanism 71, a connecting sleeve feeding track 72, a connecting sleeve in-place detection mechanism 73, a connecting sleeve pushing mechanism 74, and a connecting sleeve assembly mechanism 75, which are used for feeding and assembling the connecting block.

[0070] The connecting sleeve feeding mechanism 71 adopts but is not limited to a vibration plate, which is used for automatic sorting and feeding of connecting blocks.

[0071] The connecting sleeve feeding track 72 is installed on the machine base 1 , and one end of the connecting sleeve feeding track 72 is connected to the connecting sleeve feeding mechanism 71 and matched with the connecting block. The connecting sleeves provided by the connecting sleeve feeding mechanism 71 can be sorted and transported along the connecting sleeve feeding track 72 .

[0072] The connecting sleeve in-place detection mechanism 73 is arranged at the end of the connecting sleeve feeding track 72, and is used to receive the connecting sleeve and realize in-place detection through a proximity switch, so as to sense whether the connecting sleeve is delivered in place.

[0073] The connecting sleeve pushing mechanism 74 is arranged below the connecting sleeve in-place detection mechanism 73, and comprises a fifth pushing cylinder for pushing the connecting sleeve in-place detection mechanism 73 upwards.

[0074] The connection sleeve assembly mechanism 75 includes a third moving assembly 751, a third clamping assembly 752, and a third positioning platen 753. The third moving assembly 751 uses three groups of linear drive modules driven by cylinders, which can realize movement along the XYZ three-axis directions. The third clamping assembly 752 and the third positioning platen 753 are installed on the third moving assembly 751 and can move synchronously with the third moving assembly 751. The third clamping assembly 752 uses a pneumatic clamp to clamp the connection sleeve. The third positioning platen 753 can press the connection sleeve when the third clamping assembly 752 grabs or assembles the connection sleeve, ensuring that the position of the connection sleeve is accurate and stable, thereby improving the assembly success rate.

[0075] During operation, the connecting sleeve is continuously fed by the connecting sleeve feeding mechanism 71 and continuously fed along the connecting sleeve feeding track 72. When the connecting sleeve reaches the connecting sleeve in-place detection mechanism 73 and touches the proximity switch, the fifth pushing cylinder is actuated to push the connecting sleeve in-place detection mechanism 73 upward as a whole, and then it is clamped by the third clamping assembly 752. The third moving assembly 751 drives the third clamping assembly 752 to move toward the direction of the positioning carrier and accurately places the connecting sleeve in the second positioning groove of the positioning carrier.

[0076] like Fig.16 As shown, the long axis guiding device 13 includes a first guiding rod 131 and a sixth pushing cylinder 132 capable of driving the first guiding rod 131 to move horizontally. The first guiding rod 131 corresponds to the first positioning hole of the positioning vehicle and is used for positioning detection between the connecting shaft and the connecting block.

[0077] During operation, the sixth pushing cylinder 132 can push the first guide rod 131 to extend toward the positioning carrier and insert it into the first positioning hole. If the first guide rod 131 is pushed to the bottom and passes through the connecting shaft and the connecting block in sequence, it is determined that the holes between the connecting shaft and the connecting block are aligned, and the subsequent long axis assembly process can be carried out normally. If the first guide rod 131 is obstructed and cannot be completely pushed out, it is determined that the holes between the connecting shaft and the connecting block are not aligned, and the subsequent assembly operation cannot be carried out. It is regarded as an unqualified product, and the system controls the subsequent processes so that each process does not work to avoid forced assembly and damage to the equipment.

[0078] like Figure 17-18 As shown, the long-axis assembly device 8 includes a long-axis feeding mechanism 81, a long-axis feeding track 82, a long-axis arrival detection mechanism 83, a long-axis pushing mechanism 84, and a long-axis assembly mechanism 85, which are used for feeding and assembling the long-axis.

[0079] The long axis feeding mechanism 81 adopts but is not limited to a vibration plate, which is used for automatic sorting and feeding of long axes.

[0080] The long axis feeding track 82 is installed on the machine base 1 , and one end of the long axis feeding track 82 is connected to the long axis feeding mechanism 81 and matched with the long axis. The long axis provided by the long axis feeding mechanism 81 can be sorted and transported along the long axis feeding track 82 .

[0081] The long shaft arrival detection mechanism 83 is arranged at the end of the long shaft feeding track 82, and is used to receive the long shaft and realize arrival detection through a proximity switch, so as to sense whether the long shaft is delivered to the position.

[0082] The long-axis pushing mechanism 84 is arranged on the side of the long-axis in-place detection mechanism 83, and includes a seventh pushing cylinder for pushing the long-axis in-place detection mechanism 83 to the side.

[0083] The long axis assembly mechanism 85 includes a second push rod 851 and an eighth push cylinder 852 capable of driving the second push rod 851 to move. The second push rod 851 can push the long axis into the positioning carrier to connect with the connecting shaft and the connecting block.

[0084] During operation, the long axis is continuously fed by the long axis feeding mechanism 81 and continuously fed along the long axis feeding track 82. When the long axis reaches the long axis in-position detection mechanism 83 and touches the proximity switch, the seventh pushing cylinder is activated and pushes the long axis in-position detection mechanism 83 to the side. Finally, the eighth pushing cylinder 852 is activated and pushes the second push rod 851. The second push rod 851 pushes the long axis into the positioning carrier to connect it with the connecting shaft and the connecting block.

[0085] like Fig.19 As shown, the short axis guide device 14 includes a second guide rod 141 and a ninth push cylinder 142 capable of driving the second guide rod 141 to move vertically, and the second guide rod 141 corresponds to the second positioning hole of the positioning carrier. The short axis guide device 14 is provided with two groups, and is symmetrically arranged up and down, respectively used for positioning detection at the upper and lower ends between the connecting block and the connecting sleeve.

[0086] During operation, the ninth pushing cylinder 142 can push the second guide rod 141 to extend toward the positioning carrier. If the second guide rod 141 is pushed to the bottom and passes through the connecting sleeve and the connecting block in sequence, it is determined that the holes between the connecting sleeve and the connecting block are aligned, and the subsequent short shaft assembly and subsequent riveting processes can be carried out normally. If the second guide rod 141 is obstructed and cannot be completely pushed out, it is determined that the holes between the connecting sleeve and the connecting block are not aligned, and the subsequent assembly operation cannot be carried out. It is regarded as an unqualified product, and the system controls the subsequent processes so that each process does not work to avoid forced assembly and cause damage to the equipment.

[0087] like Fig. 20 As shown, the short shaft assembly device 9 includes a short shaft feeding mechanism 91, a short shaft guide seat 92, a short shaft pushing mechanism 93, and a short shaft assembly mechanism 94, which are used for feeding and assembling the short shaft.

[0090] The short shaft pushing mechanism 93 includes a pushing block 931 and a tenth pushing cylinder 932. The pushing block 931 is slidably arranged in the short shaft guide seat 92 and is formed with a guide groove which is longitudinally arranged and adapted to the short shaft. The tenth pushing cylinder 932 can push the pushing block 931 so that its guide groove corresponds to the feed port 921 or the discharge port 922.

[0091] The short shaft assembly mechanism 94 includes a third push rod 941 and an eleventh push cylinder 942 capable of driving the third push rod 941 to move. The third push rod 941 can push the short shaft into the positioning carrier to connect with the connecting sleeve and the connecting block.

[0092] Among them, there are two groups of short shaft assembly devices 9, which are arranged correspondingly in the upper and lower parts, and are respectively used to install the upper and lower short shafts into the connecting sleeves and the connecting blocks for connection.

[0093] During operation, the short shaft feeding mechanism 91 continuously feeds material, and the material falls into the guide groove of the push block 931 through the material pipe and the feed port 921 of the short shaft guide seat 92, and then the tenth push cylinder 932 pushes the push block 931 to move the short shaft to the discharge port 922 position, and finally the eleventh push cylinder 942 pushes the third push rod 941 to push the short shaft into the positioning carrier to connect it with the connecting sleeve and the connecting block.

[0094] like Fig.21 As shown, the riveting device 10 includes upper and lower corresponding rivet heads and a power source for pushing the rivet heads to move. The two rivet heads can rivet and fix the short shaft.

[0095] like Fig. 22 As shown, the positioning clamp opening device 11 includes a fourth push rod 111 and a twelfth pushing cylinder 112 for pushing the fourth push rod 111. The fourth push rod 111 corresponds to the second clamping plate of the positioning carrier. The twelfth pushing cylinder 112 can push the fourth push rod 111, and the fourth push rod 111 can push the second clamping plate to move, so that the positioning clamp comes to the second closed position.

[0096] like Fig.23As shown, the unloading device 12 includes an unloading guide plate 121, an unloading manipulator 122, and a fourth moving assembly 123 capable of driving the unloading manipulator 122 to move up and down and in translation.
