[0072] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0073] It should be noted that when a component is said to be "connected" to another component, it can be directly connected to the other component or it can be connected to a component in between. When a component is said to be "set on" another component, it can be directly set on the other component or it may be set to a component in between.

[0074] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0075] like Figures 1 to 22As shown, this application provides a pin assembly mechanism 101 for a clamp assembly machine 100; it includes a riveting device 401, a movable base 20, and a drive device 50. The riveting device 401 is configured to press a pin 92 to rivet and fix it to the clamp 90. The riveting device 401 includes a punch 40, a pressing lever 42 for driving the punch 40 to press the pin 92, and a pressing wedge 43 for driving the pressing lever 42 to swing. The punch 40 and the pressing lever 42 are movably coupled to the movable base 20; the drive device 50... The device has an output member 51, and a stamping wedge 43 is fixed to the output member 51. The output member 51 applies force to the movable base 20 by means of at least one retractable elastic member 52 to drive the movable base 20 to move from a first position to a second position in a first direction. In the second position, the movable base 20 is restricted from further movement in the first direction, and the output member 51 continues to move in the first direction by compressing the elastic member 52, so that the stamping wedge 43 can drive the stamping lever 42 to swing to rivet the pin 92.

[0076] Output component 51 provides power; output component 51 drives the movable base 20 to move and simultaneously drives the stamping wedge 43 to move; the movement of the stamping wedge 43 and the movement of the movable base 20 share the same output component 51, so as to reduce the cost of the pin assembly mechanism 101. When the movable base 20 is in the first position, the pin assembly mechanism 101 can perform other process operations on the clamp 90, such as inserting the pin 92 into the pin hole of the clamp 90; after the output component 51 drives the movable base 20 to move from the first position to the second position along the first direction, the movable base 20 is restricted to continue moving in the first direction in the second position. At this time, the output component 51 compresses the elastic component 52 to continue moving along the first direction, and the output component 51 drives the stamping wedge 43, so that the stamping wedge 43 can drive the stamping lever 42 to swing to rivet the pin 92, which can achieve the effect of riveting the pin 92 of the clamp 90, thereby improving the assembly efficiency of the clamp 90.

[0077] In this embodiment, as Figures 1 to 2As shown, the clamp 90 includes two clamping bodies 91 and a pin 92. Each clamping body 91 has a pin hole through which the pin 92 passes. The two clamping bodies 91 include a first clamping body 911 and a second clamping body 912. The first clamping body 911 has a first pin hole through which the pin 92 passes, and the second clamping body 912 has a second pin hole through which the pin 92 passes. After the first pin hole and the second pin hole of the first clamping body 911 are aligned, the pin 92 is inserted into the first pin hole and the second pin hole, and then the pin 92 is riveted to form the clamp 90. One end of the pin 92 has a limiting head 921, and the other end has a riveting part 922. After the riveting part 922 passes through each pin hole, it is riveted by a punch 40 to form a riveting head. Each pin hole is located between the riveting head and the limiting head 921, and the riveting head and the limiting head 921 can prevent the pin 92 from disengaging from the pin hole. The pin 92 has a riveting groove 923 at one end facing away from the limiting head 921 to form a riveting part 922; when the punch 40 presses against the riveting part 922, the riveting part 922 deforms and expands outward along the radial direction of the pin 92 to form a riveting joint, so that the punch 40 rivets the pin 92.

[0078] In this embodiment, as Figures 3 to 9 As shown, the shape of the movable base 20 is not strictly limited; for example, the movable base 20 is roughly a frame structure. The movable base 20 reciprocates along the first direction, that is, the movable base 20 reciprocates between the first position and the second position, allowing the movable base 20 to switch between the first position and the second position. The movable base 20 moves from the first position to the second position, or from the second position to the first position, to facilitate the switching of each process of the pin assembly mechanism 101, thereby improving the efficiency of the pin assembly mechanism 101. In the second position, the movable base 20 is restricted from further movement in the first direction; that is, when the movable base is in the second position, it cannot move away from the first position. The first direction is, for example... Figure 7 The X direction in the equation.

[0079] In this embodiment, as Figures 3 to 9As shown, the output component 51 is a cylinder or hydraulic cylinder, and has a cylinder body 511 and a piston rod 512 that moves in a first direction; the piston rod 512 cooperates with the cylinder body 511 and can reciprocate along the cylinder body 511. An elastic component 52 is disposed between the piston rod 512 and the movable base 20, and a stamping wedge 43 is fixed to the piston rod 512; when the piston rod 512 drives the movable base 20 to move, it can synchronously drive the stamping wedge 43 to move. The elastic component 52 is a spring; the movable base 20 has a groove, one end of the elastic component 52 is sleeved on the piston rod 512, and the other end is located in the groove, so that the elastic component 52 can be installed between the movable base and the piston rod 512. During the process of the movable base 20 moving from the first position to the second position, there is a certain distance between the piston rod 512 and the movable base 20, so that when the elastic component 52 is compressed, the piston rod 512 has a certain amount of movement when moving towards the movable base 20. The piston rod 512 moves in the first direction, and the force of the piston rod 512 can act on the elastic member 52, and then act on the movable base 20 through the elastic member 52. During the process of the output member 51 driving the movable base 20 to move from the first position to the second position, the change in the elastic member 52 is small, and the distance between the piston rod 512 and the movable base 20 remains relatively constant; when the movable base 20 moves to the second position, the movement of the movable base 20 is restricted, and the piston rod 512 continues to move towards the movable base 20 and compress the elastic member 52, so that the stamping wedge 43 can drive the stamping lever 42 to swing.

[0080] In this embodiment, as Figures 5 to 9 As shown, the stamping wedge 43 is fixed to the piston rod 512 by welding or bolts. The stamping wedge 43 has a guide ramp 441 that cooperates with the stamping lever 42; the stamping wedge 43 drives the stamping lever 42 to swing through the guide ramp 441. During the movement of the movable base 20 from the first position to the second position, the stamping wedge 43 is restricted from driving the stamping lever 42 to produce a swing suitable for riveting; during the movement of the movable base 20 from the first position to the second position, the change in the elastic member 52 is small, and the change in the distance between the piston rod 512 and the movable base 20 is insufficient to allow the stamping wedge 43 to drive the stamping lever 42 to produce a swing suitable for riveting. The stamping lever 42 has a length direction, and the stamping lever 42 is hinged to the movable base 20 at the middle of the length direction. One end of the stamping lever 42 abuts against the stamping wedge 43, and the other end abuts against the punch 40; the stamping lever 42 can slide along the guide ramp 441 of the stamping wedge. Along the length of the stamping lever 42, the middle part of the stamping lever 42 is located between the two ends. When one end of the stamping lever 42 swings, the other end of the stamping lever 42 will also swing. The movable base 20 also has a mounting part 22, and the middle part of the stamping lever 42 is rotatably mounted to the mounting part 22 by a pin. The mounting part 22 facilitates the installation of the stamping lever 42.

[0081] In this embodiment, as Figures 5 to 9 As shown, the punch 40 has a rod-shaped structure; the punch 40 has an axis in space, and a first end and a second end arranged opposite to each other along its own axis. The first end of the punch 40 abuts against the punching lever 42, and the second end of the punch 40 is used to rivet the rivet; the punch 40 moves in a second direction to rivet the pin 92; wherein, the first direction and the second direction are perpendicular; the axis of the punch 40 is parallel to the second direction. The second end of the punch 40 has a tapered structure 41 for riveting the pin 92. When the tapered structure 41 extends into the riveting groove 923, the punch 40 continues to move towards the pin 92, the tapered structure 41 abuts against the outer wall of the riveting groove 923, and pushes the outer wall of the riveting groove 923 to expand outward to form a rivet joint. The movable base 20 has a first guide groove, through which the punch 40 passes and moves in a second direction. The first guide groove limits the movement of the punch 40, ensuring it moves in a fixed direction. The punch 40 is positioned above the point where it abuts against the pressing lever 42. The punch 40 has a certain weight, or its first end may have a counterweight, ensuring it remains in contact with the pressing lever 42. The second direction, for example... Figure 7 in the Y direction.

[0082] In this embodiment, as Figures 5 to 9 As shown, the pin assembly mechanism 101 also includes a guide 30, which is movably configured on the movable base 20. When the movable base 20 is in the first position, the guide 30 can pass through the pin hole of the clamp 90 to guide the pin 92 through the pin hole. The movable base 20 has a second guide groove, through which the guide 30 passes and moves along a second direction. The second guide groove limits the movement of the guide 30 so that it moves in a fixed direction. The guide 30 is rod-shaped and has an axis in space. The second direction is parallel to the axis of the guide 30. After the guide 30 passes through the pin hole from the initial position along the second direction and engages with the pin 92, the guide 30, together with the pin 92, moves back to the initial position along the second direction, bringing the pin 92 into the pin hole. To ensure that the pin 92 passes stably through the pin hole, the guide 30 can rotate about an axis; the guide 30 can be driven to rotate by a motor 32. The pin assembly mechanism 101 also includes a first drive cylinder 31, which is mounted on a movable base and is used to drive the guide 30 to move in a third direction. When the pin 92 is engaged, the first end of the guide 30 can be located within the riveting groove 923 of the pin 92.

[0083] In this embodiment, as Figures 3 to 22As shown, the pin assembly mechanism 101 also includes a conveying assembly 80 for conveying the pin 92. The conveying assembly 80 includes a conveying member 801 and a releasing member 83. The conveying member 801 has a conveying channel 802 and a conveying port 803 communicating with the conveying channel 802. The conveying channel 802 is used to convey the pin 92, and the conveying port 803 is located above the pin hole of the clamp 90. The releasing member 83 is disposed on the conveying member 801 and cooperates with the conveying port 803 to release the pin 92 located within the conveying channel 802. When the pin 92 is assembled into the pin hole, the releasing member 83 releases the pin 92 from the conveying channel 802, and the pin 92 enters the pin hole under the guidance of the guide member 30. When the movable base 20 is in the first position, the guide member 30 passes through the pin hole and cooperates with the pin 92, and the releasing member 83 releases the pin 92 so that the pin 92 is introduced into the pin hole along with the guide member 30. When the guide 30 is not engaged with the pin 92, the release member 83 restricts the pin 92 within the transport channel 802.

[0084] In this embodiment, as Figures 1 to 18 As shown, the conveying assembly 80 also includes a mounting frame 84, a feeding seat 85, a feeding component 86, and a driving component 87. The feeding seat 85 is movably configured on the mounting frame 84 and has a feeding channel 851, which has an inlet 852 and an outlet 853. The feeding component 86 is configured on the mounting frame 84. The driving component 87 is configured on the mounting frame 84 and drives the feeding seat 85 to move from a third position to a fourth position. In the third position, the first vibrating plate 81 can convey the pin 92 from the inlet 852 to the feeding channel 851. In the fourth position, the feeding component 86 can drive the pin 92 in the feeding channel 851 into the conveying channel 802 and cause the release component 83 to release the pin 92 located in the conveying channel 802. When the loading seat 85 is in the third position, the pin 92 enters the loading channel 851 through the feed port 852. The driving component 87 drives the loading seat 85 to the fourth position, and the loading component 86 pushes the pin 92, causing the pin 92 to enter the conveying channel 802 through the discharge port 853. The pin 92 falls into the release component 83, and at this time, the loading component 86 continues to push the pin 92, causing the pin 92 to push against the release component 83, thereby releasing the pin 92. The conveyor component 801 is configured on the mounting frame 84; the conveyor component 801 is located below the loading seat 85. The conveyor component 801 is fixedly installed on the mounting frame 84 by welding or bolts.

[0085] In this embodiment, as Figures 1 to 18As shown, in the second position, the movable base 20 has the feeding component 86 pressing against the pin 92 located in the pin hole. The feeding component 86 extends out of the conveying channel 802 and presses against the pin 92; wherein, the punch 40 acts on one end of the pin 92 and is positioned opposite to the other end of the feeding component 86 pressing against the pin 92. When the movable base 20 is in the second position and the feeding component 86 presses against the pin 92 located in the pin hole, the punch 40 can fix the pin 92 in the pin hole.

[0086] In this embodiment, as Figures 1 to 18As shown, the structural shape of the mounting frame 84 is not strictly limited; the mounting frame 84 only needs to support the loading seat 85, the conveying component 801, and the driving component 87. The loading seat 85 is generally a block structure; the inlet 852 and the outlet 853 are located on opposite sides of the loading seat 85; the inlet 852 is located at the top of the loading seat 85, and the outlet 853 is located at the bottom of the loading seat 85. The mounting frame 84 has a guide rail 841, and the loading seat 85 has a guide groove that mates with the guide rail 841. The loading seat 85 can slide along the guide rail 841, allowing it to reciprocate between a third position and a fourth position. The loading seat 85 reciprocates between the third and fourth positions along a third direction; the third direction is perpendicular to both the first and second directions. The feeding component 86 is generally rod-shaped; one end of the feeding component 86 is connected to the first cylinder 861, and the other end can abut against the pin 92; the first cylinder 861 can drive the feeding component 86 to reciprocate in a second direction. The driving component 87 is a cylinder, the cylinder body is mounted on the mounting bracket 84, and the piston is connected to the feeding seat 85. The feeding seat 85 includes a main body 854 and two sliders 855. The main body 854 has a sliding groove 8541, and both sliders 855 are slidably connected to the sliding groove 8541. The feeding channel 851, the inlet 852, and the outlet 853 are all located in the main body 854; the two sliders 855 have a first state and a second state; in the first state, the two sliders 855 are in contact with each other, and a channel is formed between the two sliders 855. This channel is connected to the inlet 852, and part of the structure of the pin 92 can extend into the feeding channel 851 through the channel. The limiting head 921 of the pin 92 is located outside the channel and is in contact with the slider 855; in the second state, the inner diameter of the channel between the two sliders 855 increases, and the limiting head 921 of the pin 92 can pass through the channel and enter the feeding channel 851. The loading seat 85 also includes two guide posts 856 and two springs 857. The two guide posts 856 are respectively installed on the corresponding sliders 855. The main body 854 has two guide grooves 8542. Each guide post 856 is located in the corresponding guide groove 8542 and can slide along the guide groove 8542. The springs 857 press against the guide posts 856 and the main body 854 to drive the two sliders 855 to be in the first state. Part of the structure of the pin 92 can extend into the loading channel 851 through the channel, and the limiting head 921 of the pin 92 is located outside the channel and is in contact with the slider 855. The loading component 86 pushes the pin 92, which can make the two sliders 855 move in opposite directions. The two sliders 855 switch from the first state to the second state until the limiting head 921 enters the loading channel 851.

[0087] In this embodiment, as Figures 1 to 18As shown, the release member 83 includes two claw portions 831. A coil spring is provided between the claw portions 831 and the conveyor 801. The coil spring can drive the two claw portions 831 to restrict the pin 92 in the conveying channel 802. The two claw portions 831 have a first state and a second state. In the first state, the structures of the two claw portions 831 are partially engaged, and the claw portions 831 restrict the pin 92 in the conveying channel 802. In the second state, the two claw portions 831 rotate relative to the conveyor 801, and the gap between the two claw portions 831 allows the pin 92 to pass through, so as to release the pin 92. In the first state, a through hole 832 is formed between the two claws 831. Part of the structure of the pin 92 can be located in the through hole 832 and extend into the conveying channel 802. The limiting head 921 of the pin 92 is located in the conveying channel 802 and fits against the two claws 831 to restrict the movement of the pin 92. The loading component 86 pushes the pin 92, and the pin 92 pushes the two claws 831 to switch from the first state to the second state. The gap between the two claws 831 allows the limiting head 921 of the pin 92 to pass through so that the pin 92 can be released.

[0088] In this embodiment, as Figures 10 to 18 As shown, the conveying assembly 80 also includes a second cylinder 862 and a locking block 863; the second cylinder 862 is mounted on the mounting bracket 84 and can drive the locking block 863 to move; the loading component 86 has a slot 864, and the locking block 863 can extend into the slot 864 and restrict the movement of the loading component 86, so that the loading component 86 can more firmly push the pin 92. Specifically, when the movable base 20 is in the second position, the loading component 86 presses against the pin 92 located in the pin hole, and then the second cylinder 862 drives the locking block 863 to move in a third direction, and the locking block 863 can extend into the slot 864.

The slider 21 can slide along the groove 12 to change the position of the movable base 20 on the frame 10; the position of the movable base 20 on the frame 10 includes a first position and a second position. The pin assembly mechanism 101 also includes a limiting block 13, which is fixed to the frame 10 and can abut against the movable base 20, thus restricting the movable base 20 from further movement in a first direction. The limiting block 13 has a block-like structure and is fixed to the frame 10 by bolts or welding. Along the first direction, the movable base 20 moves between the output member 51 and the limiting block 13.

[0091] In this embodiment, as Figures 1 to 22 As shown, the clamp assembly machine 100 also includes a clamp 60, which is disposed on the frame 10 and is used to support two clamp bodies 91. The clamp 60 can adopt existing technology; the clamp 60 can fix the position of the first clamp body 911 and the second clamp body 912, so that the first pin hole of the first clamp body 911 and the second pin hole of the second clamp body 912 are aligned, so as to facilitate the pin 92 to pass through the first pin hole and the second pin hole.
