[0078] Figures 1 to 5 A riveting tool provided in an embodiment of the present application includes a frame 100, a first clamping device 1 and a second clamping device. The frame 100 is provided with a first positioning block 101, and the first positioning block 101 has a first positioning groove 101a; the first clamping device 1 is arranged on the frame 100 and is located below the first positioning block 101. The first clamping device 1 includes a first clamping drive 11 and a second positioning block 12 arranged at the output end of the first clamping drive 11, and the second positioning block 12 is provided with a second positioning groove 12a; wherein the first positioning groove 101a and the second positioning groove 12a are arranged correspondingly to form a positioning space for the workpiece 9 to be passed through and positioned; the second clamping device includes a second positioning block 101 movably arranged on the frame 100; The clamping assembly 2 and the third clamping assembly 3, the first positioning block 101 is located between the second clamping assembly 2 and the third clamping assembly 3; the second clamping block 21 is provided on the side of the second clamping assembly 2 facing the first positioning block 101, and the first clamping groove is provided on the side of the second clamping block 21 facing the first positioning block 101; the second clamping block 21 is located above the first positioning block 101; the third clamping assembly 3 is provided with a third clamping block 31 on the side facing the first positioning block 101, and the second clamping groove is provided on the side of the third clamping block 31 facing the first positioning block 101; the third clamping block 31 is located above the second positioning block 12; the second clamping block 21 and the third clamping block 31 can move toward each other to enclose and form a clamping space, and the clamping space is used to pass the workpiece 9.

[0079] It can be understood that the frame 100 provides an installation base; when the workpiece 9 needs to be riveted, the workpiece 9 is assembled and loaded into the positioning space, so that the lower end of the workpiece 9 is positioned in the second positioning groove 12a, and the upper part of the workpiece 9 is arranged in the first positioning block 101 and extends to the top of the first positioning block 101, and the first positioning block 101 plays a positioning role on the workpiece 9; then the second positioning block 12 is driven by the first clamping drive 11 to move toward the direction of the first positioning block 101, so that the workpiece 9 can be clamped in the positioning space; and the second clamping assembly 2 and the third clamping assembly 3 clamp and position the part of the workpiece 9 located above the first positioning block 101 through the second clamping block 21 and the third clamping block 31 respectively. After the first clamping device 1 and the second clamping device are completed to clamp and position the workpiece 9, the riveting operation can be performed on the workpiece 9 through the riveting device. The present application is particularly suitable for the stable positioning of a workpiece 9 with a long length and high material hardness, such as a push rod assembly.

[0080] like Figure 1 and Figure 5 As shown, the workpiece 9 has a cam 91 , and the cam 91 is positioned and matched with the groove wall of the first positioning groove 101 a , so that the first positioning groove 101 a plays a role in positioning and limiting the cam 91 .

[0081] In this embodiment, the first clamping drive member 11 drives the first positioning block 101 to move upward or downward, so that space can be provided for the workpiece 9 to be loaded into the riveting tool. After the workpiece 9 is loaded, the first clamping drive member 11 drives the first positioning block 101 to move upward, so that the workpiece 9 is clamped, wherein the cam 91 and the groove wall of the first positioning groove 101a are pressed against each other.

[0082] In this embodiment, the upstream portion of the workpiece 9 is clamped by the second clamping block 21 and the third clamping block 31 , and the design of the first clamping groove and the second clamping groove also plays a role in positioning the workpiece 9 .

[0083] In this embodiment, the upper, middle and lower parts of the workpiece 9 in the length direction are all clamped and positioned, thereby achieving stable positioning of the workpiece 9 with a long length.

[0084] like Figures 1 to 5 As shown, in the technical solution of this embodiment, the second clamping assembly 2 includes a second clamping drive member 22, a second push rod 23 and a second slider 24, the second clamping drive member 22 is arranged on the frame 100; the second push rod 23 is movably arranged on the frame 100 and connected to the output end of the second clamping drive member 22; the second slider 24 is slidably arranged on the frame 100, and the second slider 24 is connected to the end of the second push rod 23 away from the second clamping drive member 22; the end of the second slider 24 away from the second push rod 23 is connected to the second clamping block 21.

[0085] It can be understood that the second clamping driving member 22 provides power to drive the second push rod 23 to move, and then drive the second slider 24 to move closer to or away from the workpiece 9, thereby achieving the purpose of clamping or releasing the workpiece 9.

[0086] In this embodiment, the second clamping drive member 22 is a cylinder. In other embodiments, the second clamping drive member 22 may also be a hydraulic cylinder.

[0087] During the riveting operation, the second slider 24 is subjected to external force. If it moves under the action of the external force, especially moves toward the second clamping drive member 22, the positioning stability of the workpiece 9 is affected, thereby affecting the riveting effect. Figures 1 to 5 As shown, in the technical solution of this embodiment, it also includes a first stop assembly 6, the first stop assembly 6 includes a first stop driving member 61 and a first stop block 62, the first stop driving member 61 is arranged on the frame 100; the first stop block 62 is movably arranged on the frame 100, and is connected to the output end of the first stop driving member 61; wherein, when the second slider 24 moves to make the second clamping block 21 abut against the workpiece 9, the first stop driving member 61 drives the first stop block 62 to move to be inserted between the second slider 24 and the second clamping driving member 22, and abut against the second slider 24.

[0088] It can be understood that the first stopper assembly 6 is provided to limit the second slider 24. Specifically, after the second clamping block 21 clamps the workpiece 9 in place, the first stopper driver 61 drives the first stopper block 62 to move, and the first stopper block 62 moves between the second slider 24 and the second clamping driver 22, and abuts against the second slider 24. When the second clamping block 21 needs to release the workpiece 9, the first stopper driver 61 drives the first stopper block 62 to withdraw from between the second slider 24 and the second clamping driver 22, ensuring that the second slider 24 can move smoothly.

[0089] In this example, the first stop driving member 61 is a cylinder. In other embodiments, the first stop driving member 61 may also be a hydraulic cylinder.

[0090] like Figures 1 to 5As shown, in the technical solution of this embodiment, the third clamping assembly 3 includes a third clamping drive member 32, a third slider 33, a third push block 34 and a third matching pin 35, the third clamping drive member 32 is arranged on the frame 100; the third slider 33 is slidably arranged on the frame 100 and is connected with the third clamping block 31; the third slider 33 is provided with a third assembly hole 33a, and the penetration direction of the third assembly hole 33a is perpendicular to the sliding direction of the third slider 33; the third push block 34 is movably penetrated through the third assembly hole 33a and is connected to the output end of the third clamping drive member 32; the third push block 34 is provided with a third adjustment hole, the third adjustment hole is a strip hole, and the length direction of the third adjustment hole is set at an angle to the moving direction of the third push block 34; the third matching pin 35 is connected to the third slider 33 and is penetrated through the third adjustment hole; wherein, when the third clamping drive member 32 drives the third push block 34 to move, the hole wall of the third adjustment hole pushes the third slider 33 to move, so that the third clamping block 31 is close to or away from the workpiece 9.

[0091] It can be understood that the third clamping driving member 32 provides power to drive the third push block 34 to move along the first direction, wherein the first direction is perpendicular to the moving direction of the third slider 33. Since the third adjustment hole is an inclined hole having an angle with the first direction, and since the third matching pin 35 and the third slider 33 are fixedly connected, during the movement of the third push block 34, the hole wall of the third adjustment hole pushes the third matching pin 35 to move, thereby driving the third slider 33 to move close to or away from the workpiece 9, so that the third clamping block 31 is close to or away from the workpiece 9.

[0092] The rack 100 is provided with a third slide rail, and the third slider 33 is slidably matched with the third slide rail.

[0093] The frame 100 is also provided with a limiting hole, which is a strip-shaped hole, and the length direction of the limiting hole extends along the moving direction of the third slider 33, and the third matching pin 35 is movably inserted into the limiting hole. It can be understood that the limiting hole plays a limiting role in the moving limit position of the third matching pin 35.

[0094] In this embodiment, the third clamping drive member 32 is an oil cylinder, and the second clamping drive member 22 adopts a pneumatic cylinder. Compared with the solution in which both the second clamping drive member 22 and the third clamping drive member 32 adopt pneumatic cylinders, a greater clamping force can be obtained and the clamping is more stable.

[0095] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, in the technical solution of this embodiment, a third clamping device is also included, and the third clamping device includes a fourth clamping assembly 4 and a fifth clamping assembly 5 movably arranged on the frame 100, and the first positioning block 101 is located between the fourth clamping assembly 4 and the fifth clamping assembly 5;

[0096] A fourth clamping block 41 is provided on one side of the fourth clamping assembly 4 facing the positioning space, and a fourth friction portion 411 is provided on the fourth clamping block 41 facing the positioning space; the fourth clamping block 41 is located between the first positioning block 101 and the second positioning block 12;

[0097] A fifth clamping block 51 is provided on one side of the fifth clamping assembly 5 facing the positioning space, and a fifth friction portion 511 is provided on one side of the fifth clamping block 51 facing the positioning space; the fifth clamping block 51 is located between the first positioning block 101 and the second positioning block 12;

[0098] The fourth clamping block 41 and the fifth clamping block 51 can move toward each other, so that the fourth friction portion 411 and the fifth friction portion 511 abut against the workpiece 9 respectively.

[0099] It can be understood that the fourth clamping block 41 and the fifth clamping block 51 can be provided to further assist clamping, so that the riveting tool provided in this embodiment can be suitable for a workpiece 9 with a longer length and can further improve the clamping stability of the workpiece 9.

[0100] The design of the fourth friction portion 411 and the fifth friction portion 511 can make the fourth clamping block 41 and the fifth clamping block 51 clamp the workpiece 9 more stably.

[0101] In this embodiment, the fifth friction portion 411 and the fifth friction portion 511 both have a concave-convex structure.

[0102] like Figure 4 As shown, in the technical solution of this embodiment, the fourth clamping assembly 4 includes a fourth clamping drive member 42, a fourth push rod 43 and a fourth slider 44, the fourth clamping drive member 42 is arranged on the frame 100; the fourth push rod 43 is movably arranged on the frame 100 and connected to the output end of the fourth clamping drive member 42; the fourth slider 44 is slidably arranged on the frame 100, and the fourth slider 44 is connected to the end of the fourth push rod 43 away from the fourth clamping drive member 42; the end of the fourth slider 44 away from the fourth push rod 43 is connected to the fourth clamping block 41.

[0103] It is understandable that the fourth clamping driving member 42 provides power to drive the fourth push rod 43 to move, and then drive the fourth sliding block 44 to move closer to or away from the workpiece 9, thereby achieving the purpose of clamping or releasing the workpiece 9.

[0104] In this embodiment, the fourth clamping drive member 42 is a cylinder. In other embodiments, the fourth clamping drive member 42 may also be a hydraulic cylinder.

[0105] During the riveting operation, the fourth slider 44 is subjected to external force. If it moves under the action of the external force, especially moves toward the fourth clamping drive member 42, the positioning stability of the workpiece 9 is affected, thereby affecting the riveting effect. Figure 1 and Figure 4 As shown, in the technical solution of this embodiment, it also includes a second stop assembly 7, the second stop assembly 7 includes a second stop driving member 71 and a second stop block 72, the second stop driving member 71 is arranged on the frame 100; the second stop block 72 is movably arranged on the frame 100, and is connected to the output end of the second stop driving member 71; wherein, when the fourth slider 44 moves to make the fourth clamping block 41 abut against the workpiece 9, the second stop driving member 71 drives the second stop block 72 to move to be inserted between the fourth slider 44 and the fourth clamping driving member 42, and abut against the fourth slider 44.

[0106] It can be understood that the second stopper assembly 7 is provided to limit the fourth slider 44. Specifically, after the fourth clamping block 41 clamps the workpiece 9 in place, the second stopper driver 71 drives the second stopper block 72 to move, and the second stopper block 72 moves between the fourth slider 44 and the fourth clamping driver 42, and abuts against the fourth slider 44. When the fourth clamping block 41 needs to release the workpiece 9, the second stopper driver 71 drives the second stopper block 72 to withdraw from between the fourth slider 44 and the fourth clamping driver 42, ensuring that the fourth slider 44 can move smoothly.

[0107] In this embodiment, the second stop driving member 71 is a cylinder; in other embodiments, the second stop driving member 71 may also be a hydraulic cylinder.

[0108] like Figure 1 and Figure 4 As shown, in the technical solution of this embodiment, the fifth clamping assembly 5 includes a fifth clamping driving member 52, a fifth slider 53, a fifth push block 54 and a fifth matching pin 55, the fifth clamping driving member 52 is arranged on the frame 100; the fifth slider 53 is slidably arranged on the frame 100 and is connected with the fifth clamping block 51; the fifth slider 53 is provided with a fifth assembly hole 53a, and the penetration direction of the fifth assembly hole 53a is perpendicular to the sliding direction of the fifth slider 53; the fifth push block 54 is movably penetrated by the fifth assembly hole 53a and is connected to the output end of the fifth clamping driving member 52; the fifth push block 54 is provided with a fifth adjustment hole, the fifth adjustment hole is a strip hole, and the length direction of the fifth adjustment hole is set at an angle with the moving direction of the fifth push block 54; the fifth matching pin 55 is connected to the fifth slider 53 and penetrated by the fifth adjustment hole;

[0109] When the fifth clamping driving member 52 drives the fifth pushing block 54 to move, the hole wall of the fifth adjusting hole pushes the fifth sliding block 53 to move, so that the fifth clamping block 51 is close to or away from the workpiece 9 .

[0110] It can be understood that the fifth clamping driving member 52 provides power to drive the fifth push block 54 to move along the first direction, wherein the first direction is perpendicular to the moving direction of the fifth slider 53. Since the fifth adjustment hole is an inclined hole having an angle with the first direction, and since the fifth matching pin 55 is fixedly connected to the fifth slider 53, during the movement of the fifth push block 54, the hole wall of the fifth adjustment hole pushes the fifth matching pin 55 to move, thereby driving the fifth slider 53 to move close to or away from the workpiece 9, so that the fifth clamping block 51 is close to or away from the workpiece 9.

[0111] The rack 100 is provided with a fifth slide rail, and the fifth slider 53 is slidably matched with the fifth slide rail.

[0112] The frame 100 is also provided with a limiting hole, which is a strip-shaped hole, and the length direction of the limiting hole extends along the moving direction of the third slider 33, and the fifth matching pin 55 is movably inserted into the limiting hole. It can be understood that the limiting hole plays a limiting role in the moving limit position of the fifth matching pin 55.

[0113] In this embodiment, the fifth clamping drive member 52 is an oil cylinder, and the fourth clamping drive member 42 adopts a pneumatic cylinder. Compared with the solution in which both the fifth clamping drive member 52 and the fourth clamping drive member 42 adopt pneumatic cylinders, a greater clamping force can be obtained and the clamping is more stable.

[0114] In this embodiment, the third clamping drive member 32 and the fifth clamping drive member 52 share an oil circuit, so that the third clamping block 31 and the fifth clamping block 51 can move synchronously.

[0115] In this embodiment, a proximity switch 8 is further provided. The proximity switch 8 is provided on the frame 100 and is arranged close to the fifth clamping assembly for detecting whether the clamping is in place.
