DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4 The utility model provides a technical solution: a gun mud clamp, including a gripping component 1, a transverse buffer component 2 is arranged above the gripping component 1, and a transverse buffer amount is provided to enable the clamp to adapt to the angle and shape of the gun mud, a longitudinal buffer component 3 is arranged above the transverse buffer component 2, and a longitudinal buffer amount is provided to prevent the clamp from being bent and damaged due to rigid contact between the clamp and the gun mud, and a rotating component 4 is arranged above the longitudinal buffer component 3, which can adjust the clamping angle of the clamp to further adapt to the shape of the gun mud.

[0023] The transverse buffer assembly 2 includes a limit piece 21, a transverse limit groove 22 is provided inside the limit piece 21, and a movable disc 23 is arranged inside the transverse limit groove 22. Balls 24 rolling against the inner wall of the transverse limit groove 22 are arranged on the top and bottom of the movable disc 23. A connecting rod 25 extending to the bottom of the limit piece 21 is fixedly connected to the bottom of the movable disc 23. A reset assembly 26 is arranged around the movable disc 23. There are 6 reset assemblies 26 evenly distributed around the movable disc 23, so that the movable disc 23 can move in different directions in the transverse limit groove 22.

[0024] The reset assembly 26 includes a movable rod 261 that transversely penetrates the limit piece 21 and extends to the inside of the transverse limit groove 22. The end of the movable rod 261 located outside the limit piece 21 is fixedly connected to a first stop block 262, and the end of the movable rod 261 located inside the transverse limit groove 22 is fixedly connected to a second stop block 263. A first reset spring 264 mounted on the surface of the movable rod 261 is fixedly connected between the second stop block 263 and the inner wall of the transverse limit groove 22. After clamping the gun mud, the reset assembly 26 can reset the movable disc 23 to its initial position.

[0025] The longitudinal buffer assembly 3 includes a longitudinal limit groove 31 provided inside the limit member 21, and also includes a limit rod 32 which longitudinally penetrates the limit member and extends to the inside of the longitudinal limit groove 31. One end of the limit rod 32 located inside the longitudinal limit groove 31 is fixedly connected to a third stopper 33, and one end of the longitudinal limit rod 32 located above the limit member 21 is fixedly connected to a first connecting disk 34. An annular turntable is arranged between the bottom of the speed reduction mechanism 42 and the top of the first connecting disk 34, which is used to bear the main weight of all structures below the first connecting disk 34, thereby preventing the output end of the speed reduction mechanism 42 from bearing weight and protecting the speed reduction mechanism 42. A second return spring 35 which is sleeved on the surface of the limit rod 32 is fixedly connected between the bottom of the first connecting disk 34 and the top of the limit member 21. When clamping the gun mud, the cone thorn 15 contacts the gun mud, so that the clamp is subjected to force, and the second return spring 35 is compressed. After the gun mud is clamped, the second return spring 35 returns to its original state.

[0026] The rotating component 4 includes a motor 41 and a reduction mechanism 42. The reduction mechanism 42 can adopt a reducer. The entire clamp can be fixed to the robotic arm by bolts, and the output end of the motor 41 is fixedly connected to the input end of the reduction mechanism 42. The output end of the reduction mechanism 42 is fixedly connected to the top of the first connecting disk 34 through a connecting shaft. The motor 41 rotates, and the rotational motion is transmitted to the first connecting disk 34 after being decelerated by the reduction mechanism 42, thereby adjusting the clamping angle of the clamping component 1 below.

[0027] The gripping assembly 1 includes a second connecting disk 11 fixedly connected to one end of the connecting rod 25 extending to the bottom of the limit member 21, both sides of the bottom of the second connecting disk 11 are rotatably connected to movable arms 12 through connecting members, a telescopic rod 13 is fixedly connected to the center position of the bottom of the second connecting disk 11, and the output end of the telescopic rod 13 is rotatably connected to two transmission members 14 through a connecting member, and the ends of the two transmission members 14 away from the telescopic rod 13 are respectively rotatably connected to the two movable arms 12 through a rotating shaft, and the ends of the movable arms 12 away from the second connecting disk 11 are fixedly connected to a cone thorn 15, and the contraction of the telescopic rod 13 can drive the movable arms 12 on both sides to rotate, further causing the cone thorn 15 to move, thereby realizing the gripping function.

[0028] When in use, the clamp is fixed to the mechanical arm by bolts, and the motor 41 works. After being decelerated by the reducer 42, it drives the first connecting plate 34 to rotate, and then drives the limit member 21 to rotate, and further drives the clamping assembly 1 to rotate, and adjusts the clamping direction. The mechanical arm moves and drives the clamp to move to the cannon mud. The telescopic rod 13 extends, pushing the transmission member 14 to move, and further pushes the bottom of the movable arms 12 on both sides to open, ready for clamping. As the mechanical arm moves, the cone thorn 15 pierces the cannon mud, and then the telescopic rod 15 contracts, driving the bottom of the two movable arms 12 to clamp through the transmission member 14, completing the cannon mud clamping, and then the mechanical arm moves to transfer the cannon mud to other positions.

[0029] When the cone contacts the cannon clay, if the cannon clay is too hard, it will generate an upward thrust on the clamp, thereby forcing the limiter 21 to move upward and compressing the second return spring 35 to achieve the purpose of longitudinal buffering. After the cannon clay is clamped, the second return spring 35 is restored to its original state due to the weight of the clamp itself and the cannon clay, as well as the rebound force of the second return spring 35.

[0030] When clamping the cannon mud, if the shape of the cannon mud is irregular, the clamp will generate a horizontal thrust, thereby causing the second connecting disk 11 to move, and further driving the movable disc 23 to move in the transverse limit groove 22 through the connecting rod 25, so that part of the second stop block 263 is squeezed, and then the first return spring 264 is compressed. After the cannon mud is clamped, the movable disc 23 returns to its initial position under the action of the rebound force of the first return spring 264.

[0031] The embodiments of the present invention are described above in conjunction with the accompanying drawings, but the present invention is not limited to the above-mentioned specific implementation modes, which are merely illustrative rather than restrictive. Under the guidance of the present invention, ordinary technicians in this field can also make many forms without departing from the scope of protection of the present invention and the claims, all of which are within the protection of the present invention.
