[0017] In the forging of alloy steel billets, forging equipment is used for shaping. It mainly forms the alloy steel billet by applying pressure, and during the forming process, a robotic arm is used to clamp and adjust the billet in multiple directions to adapt to the downward pressing direction.

[0018] During the process of holding alloy steel billets by a robotic arm, the end in contact with the billet is mostly fixed. When processing excessively large billets, the clamping force per unit area of ​​the billet will increase significantly, forming local high pressure that may cause damage to the billet surface and reduce clamping stability.

[0019] Therefore, a clamping device for alloy steel forging billets is proposed to solve the above problems.

[0020] Please see Figure 1-3The alloy steel forging billet clamping device in this embodiment is used to be installed at the output end of the robotic arm 5. It includes a carrier frame 1, a drive mechanism and a fixing mechanism. Two crossbars 6 are fixed inside the carrier frame 1. The drive mechanism is set on the carrier frame 1 and the fixing mechanism is set on the carrier frame 1. It is used to clamp the alloy steel billet driven by the drive mechanism. The fixing mechanism includes a double-headed screw 8 and two sets of front and rear adjusting clamps 13. The double-headed screw 8 is used to adjust the distance between the two sets of front and rear adjusting clamps 13 and adapt to the alloy steel billet. One set of adjusting clamps 13 includes two adjusting clamps 13.

[0021] Specifically, the drive mechanism can drive the fixing mechanism to clamp the alloy steel billet, and then drive the clamped alloy steel billet to rotate. The fixing mechanism can adjust the distance between the front and rear sets of adjusting clamps 13 by rotating the double-headed screw 8, so that the stress distribution is uniform, the local overload wind is reduced, and the alloy steel billet is prevented from being damaged.

[0022] It should be noted that the robotic arm 5 is existing technology and one of the core devices in modern industrial automation and intelligent manufacturing, widely used in many fields. The robotic arm 5 consists of multiple rotating or linear joints and linkages, forming a motion structure similar to the human body. These joints are connected by transmission systems such as gears and belts, enabling the robotic arm 5 to move freely in three-dimensional space, so they will not be described in detail here.

[0023] In this embodiment, the driving mechanism includes a first driving part 3 and an extension cylinder 4. The first driving part 3 is located at the output end of the robotic arm 5. The output end of the first driving part 3 is fixed with a bracket 2 connected to the carrier 1. The extension cylinder 4 is located inside the bracket 2 and connected to the carrier 1. The output end of the extension cylinder 4 extends into the carrier 1 and is fixed with a movable block 7.

[0024] Specifically, during use, the extension cylinder 4 drives the movable block 7 to move up and down, thereby adjusting the fixing mechanism to drive the adjusting clamp 13 to clamp the alloy steel billet. Then, the first drive unit 3 can drive the alloy steel billet to rotate and flip, so that the alloy steel billet can be forged flexibly.

[0025] In this embodiment, the fixing mechanism also includes two movable seats 10 and four plate frames 11. The four plate frames 11 are evenly sleeved on the two crossbars 6. The two movable seats 10 are respectively threaded onto the outer ends of the double-headed screw 8. The left and right sides of the two movable seats 10 are respectively hinged to a connecting rod 12 with one end hinged to the four plate frames 11. The plate frame 11 has a mounting surface. The adjusting clamp 13 is set on the mounting surface. The double-headed screw 8 is set in the movable block 7 through a bearing.

[0026] Specifically, rotating the double-headed screw 8 can drive the two movable seats 10 to move relative to or away from each other on the crossbar 6, thereby driving the corresponding plate frame 11 to move relative to or away from each other via the connecting rod 12, realizing the change of the distance between the front and rear adjustable clamping plates 13, thus adapting to the dispersed clamping of different types of alloy steel billets, avoiding stress concentration, and making the clamping stable.

[0027] When the output end of the extension cylinder 4 retracts, it can drive the movable block 7 to move upward, thereby driving the double-headed screw 8 to move the movable seat 10 upward. This allows the connecting rod 12 to drive the plate frame 11 to rotate in the direction of the double-headed screw 8 with the crossbar 6 as the center, thereby achieving the clamping of the alloy steel billet.

[0028] In this embodiment, a cleaning mechanism is also included. The cleaning mechanism includes two U-shaped frames 15 and two drive seats 14. The two drive seats 14 are fixed on the left and right sides of the movable block 7, respectively. The two U-shaped frames 15 are respectively sleeved on the two crossbars 6. A transmission frame 16 with one end hinged to the U-shaped frame 15 is connected inside the drive seat 14. An adjustment plate 17 is rotatably installed inside the U-shaped frame 15. The rotating shaft of the adjustment plate 17 extends to the outside of the U-shaped frame 15. A jet nozzle 20 is provided on one side of the adjustment plate 17, and a fixed clamping plate 19 is provided on the other side. A second drive part 18 with its output end fixedly connected to the rotating shaft of the adjustment plate 17 is fixed outside the U-shaped frame 15.

[0029] Specifically, when the robotic arm 5 moves the entire device to the outside of the alloy steel billet, the first drive unit 3 is activated, so that the alloy steel billet is between the two adjusting clamps 13 inside the two sets of adjusting clamps 13. At this time, the jet head 20 connected to the high-pressure air pipe is activated to blow away and clean the debris on the outside of the alloy steel billet. Then, the output end of the extension cylinder 4 is activated to retract, and the moving block 7 drives the driving seat 14 to rise, thereby driving the U-shaped frame 15 to rotate in the direction of the double-headed screw 8 with the crossbar 6 as the center. At the same time, the jet head 20 is closed, and the second drive unit 18 is activated to drive the adjusting plate 17 to rotate in the direction of the double-headed screw 8, driving the fixed clamp 19 to move to one side of the alloy steel billet, so that the fixed clamp 19 is added to the adjusting clamp 13 to hold the alloy steel billet together, increasing the holding area of ​​the alloy steel billet and further improving the overall clamping stability of the device.

[0030] Both the second drive unit 18 and the first drive unit 3 are brushless motors, which are electric motors that replace traditional mechanical brush commutation with electronic commutation. They have advantages such as high efficiency, long life and low maintenance cost, and are widely used in drones, electric vehicles, industrial automation and other fields. Here, the alloy steel billet can be stably rotated and the adjustment plate 17 can be stably rotated, so that the fixed clamping plate 19 and the jet head 20 can be flexibly interchanged.

[0031] In this embodiment, a handwheel 9 is fixed to one end of the double-ended screw 8 to drive the double-ended screw 8 to rotate.

[0032] It should be noted that the handwheel 9 is an operating component that enables adjustment or control of a mechanical device through manual rotation. It is widely used in the manual adjustment, position control, and start / stop operation of equipment. The handwheel 9 provides a convenient manual operation interface, allowing the double-ended screw 8 to be easily rotated and adjusted.

[0033] In this embodiment, the fixed clamping plate 19 and the adjusting clamping plate 13 are both connected to the U-shaped frame 15 and the plate frame 11 respectively by fasteners.

[0034] The fasteners are bolts, and their materials can be low-carbon steel, medium-carbon steel, alloy steel, stainless steel, and special high-temperature alloys. They can be selected according to actual needs, so that the adjusting plate 13 and the fixed plate 19 can be easily replaced after damage.

[0035] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
