Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Embodiment 1

[0024] In the prior art, when forging a workpiece, since the forging head can only punch one end face of the workpiece at a time, the operator needs to frequently use a clamp to manually clamp the workpiece and rotate or flip it to ensure that each end face can be punched evenly, so that the flatness of each face of the workpiece tends to be consistent. However, as the workload or the weight and volume of the workpiece increase, this operation will not only greatly increase the work intensity, but also increase the risk of accidents.

[0025] Therefore, in order to solve the problem that the operator needs to frequently use the clamp to manually move the workpiece during the forging process of the existing forging machine, which has a high work intensity, the function of automatically turning the workpiece is realized to achieve the purpose of reducing the work intensity and improving the work efficiency. Figure 1-Figure 2 , including a chuck 1 and jaws and a connecting block 8 respectively arranged on both sides of the chuck 1 in parallel, the jaws including a movable jaw 2 and a fixed jaw 3 parallel to each other, the movable jaw 2 and the fixed jaw 3 are both horizontally arranged on one side of the chuck 1, the connecting block 8 is fitted with the chuck 1, and a rotating shaft 15 is provided at the fitting part of the chuck 1 and the connecting block 8, the rotating shaft 15 is simultaneously penetrated through the chuck 1 and the connecting block 8, a second motor 16 is provided inside the connecting block 8, and the second motor 16 is connected to the rotating shaft 15;

[0026] In this embodiment, the first motor 4 and the second motor 16 are electrically connected to an external power source.

[0027] In this embodiment, the rotating shaft 15 is a cylinder.

[0028] Working principle: The second motor 16 can drive the rotating shaft 15 to rotate the rotating shaft 15, and drive the chuck 1 to rotate in a circle through the rotating shaft 15.

[0029] During use: when the chuck 1 clamps the workpiece, the operator can turn on the switch of the external power supply to start the second motor 16, and then the second motor 16 can rotate the shaft 15, so that the shaft 15 can drive the chuck 1 to rotate in a circle, so as to achieve the purpose of automatically flipping the workpiece clamped by the chuck 1, thereby eliminating the need for the operator to manually adjust the position of the workpiece, reducing work intensity and improving work efficiency.

[0030] Embodiment 2

[0031] On the basis of the first embodiment, the utility model further improves the adjustment effect of the chuck 1 on the position of the workpiece. Figure 2-Figure 3 , including a first motor 4 and a turntable 7. The turntable 7 is driven by the first motor 4, so that the turntable 7 can drive the clamped workpiece to rotate radially. Specifically, the first motor 4 and the transmission column 10 are provided on the side of the movable jaw 2 and the fixed jaw 3 away from the clamping surface 5, and the first motor 4 passes through the clamping jaw and is connected to the turntable 7 through the transmission column 10.

[0032] In this embodiment, the rotating disk 7 is semi-protruded at the opening of the annular groove 6 , and the bottom of the rotating disk 7 and the bottom of the annular groove 6 are in contact with each other.

[0033] In this embodiment, optionally, a protective cover may be provided on the outside of the first motor 4. The protective cover has a rectangular structure and is fixed to the chuck 1 by screws to protect the first motor 4 and help prevent the first motor 4 from being hit by external impacts when in use.

[0034] In this embodiment, a rotor is provided inside the first motor 4, and the transmission column 10 is connected to the rotor.

[0035] In this embodiment, optionally, the end surface of the turntable 7 that contacts the workpiece is a frosted surface, so that the turntable 7 can clamp the workpiece more firmly along with the clamping surface 5, which helps to prevent the workpiece from slipping or the turntable 7 from idling during radial rotation.

[0036] Working principle: By starting the first motor 4, the rotor in the first motor 4 can drive the transmission column 10 to rotate in a circle, and then the transmission column 10 can drive the turntable 7 to rotate in the annular groove 6.

[0037] During use: When it is necessary to radially rotate the workpiece clamped by the chuck 1, the operator can start the first motor 4 to allow the turntable 7 to rotate inside the annular groove 6. At this time, since the workpiece is tightly attached to the clamping surface 5 and fits tightly with the turntable 7, the workpiece can radially rotate along the rotation direction of the turntable 7, further improving the convenience of adjusting the workpiece and helping to improve work efficiency.

[0038] Embodiment 3

[0039] See also Figure 2, based on the first and second embodiments, it also includes a hydraulic cylinder 11 and a hydraulic lifting rod 12 for adjusting the clamping force;

[0040] Specifically, the fixed claw 3 is fixedly connected to the chuck 1, and the movable claw 2 is movably connected to the chuck 1. A clamping surface 5 is provided on the opposite side of the fixed claw 3 and the movable claw 2, and a hydraulic cylinder 11 is provided on the clamping surface 5 of the fixed claw 3, and a hydraulic lifting rod 12 is passed through the inside of the hydraulic cylinder 11, and the other end of the hydraulic lifting rod 12 is fixed on the clamping surface 5 of the movable claw 2.

[0041] In this embodiment, the hydraulic cylinder 11 is connected to an external hydraulic control device.

[0042] In this embodiment, by fixing the fixed claws 3 on the chuck 1 , it helps as a reference for the operator to adjust the movable claws 2 , and the operator only needs to focus on adjusting the spacing of the movable claws 2 .

[0043] Working principle: The hydraulic cylinder 11 can push the hydraulic lifting rod 12 upward or pull it downward, so that the movable claw 2 can make a vertical reciprocating motion on the chuck 1, and the versatility of the chuck 1 can be improved by changing the distance between the movable claw 2 and the fixed claw 3.

[0044] During use: When it is necessary to clamp a workpiece, the operator can place the clamping surface 5 of the fixed jaw 3 against one side of the workpiece, and then open the hydraulic cylinder 11 so that the hydraulic cylinder 11 can drive the hydraulic lifting rod 12 to adjust the height of the movable jaw 2 so that the movable jaw 2 can be tightly attached to the other side of the workpiece, so that the fixed jaw 3 and the movable jaw 2 can clamp workpieces of different sizes, and at the same time, the turntable 7 located on the clamping surface 5 can be attached to the workpiece.

[0045] In the present embodiment, in order to enable the movable claw 2 to smoothly perform lifting and lowering movements on the chuck 1, preferably, the movable claw 2 and the chuck 1 are respectively provided with an embedding block 13 and an empty slot 14 on the corresponding sides thereof, and the embedding block 13 is movably inserted into the empty slot 14. Through the above structure, when the hydraulic cylinder 11 drives the hydraulic lifting rod 12 to drive the movable claw 2, the embedding block 13 can move along the movable claw 2 inside the empty slot 14, thereby limiting the moving range of the movable claw 2, so that the movable claw 2 can only perform lifting and lowering movements along the empty slot 14, thereby avoiding the situation where the movable claw 2 has an angle deviation during the lifting process.

[0046] In the present embodiment, in order to prevent the movable claw 2 from falling off from the empty slot 14 when being raised, preferably, a limit block 17 is provided at one end of the embedded block 13 facing the empty slot 14, and a limit slot 18 is provided on the side of the empty slot 14 close to the limit block 17. Through the above structure, the limit slot 18 is a groove opened in the empty slot 14, and the two inner walls of the groove that fit the empty slot 14 are both included in the empty slot 14, so that the limit block 17 inserted in the limit slot 18 will be clamped in the empty slot 14, so as to achieve the purpose of avoiding the movable claw 2 from falling off from the chuck 1.

[0047] In this embodiment, a handle 9 is provided on the side of the connection block 8 away from the chuck 1 , and the operator can take the mobile chuck 1 by holding one end of the handle 9 .

[0048] In summary, when using the clamping assembly for forging equipment, the operator can first hold the handle 9, move one end with the chuck 1 to the workpiece to be processed, then place the fixed claw 3 against one side of the workpiece and turn on the hydraulic controller at the same time, so that the hydraulic cylinder 11 can drive the hydraulic lifting rod 12 to rise, and then the movable claw 2 can be attached to the other end of the workpiece driven by the hydraulic lifting rod 12, and then the hydraulic cylinder 11 can drive the hydraulic lifting rod 12 to retract, so that the movable claw 2 and the fixed claw 3 can be tightly clamped on both sides of the workpiece. When it is necessary to turn the workpiece over, the operator can start the second motor 16 so that the rotating shaft 15 can drive the chuck 1 to rotate in a circle, so that the workpiece clamped by the movable claw 2 and the fixed claw 3 can be flipped in the same direction, thereby achieving the effect of automatic flipping. Subsequently, when it is necessary to move the workpiece radially, the operator can start the first motor 4 so that the first motor 4 can drive the transmission column 10 to cause the turntable 7 to rotate, so that the workpiece in contact with the turntable 7 can be radially rotated in the opposite direction of the rotation of the turntable 7, further improving the processing effect on the workpiece.

[0049] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
