[0002] Metalworking is the process of processing raw or semi-finished metal materials to obtain specific shapes, sizes, precision and properties, and it encompasses a variety of processing methods.
[0003] Metalworking workpiece clamping devices are key equipment in metalworking, involving both mechanical manufacturing and metalworking fields. Their structure includes a fixed base, clamping mechanism, positioning components, and auxiliary support structure. The clamping mechanism is opened and closed through the drive component to clamp or release the workpiece, ensuring the accuracy, efficiency, and quality of metalworking.
[0004] Existing metal workpiece clamping devices are simple in structure and easy to use, and can well meet the daily needs of metal workpiece clamping. However, due to the simple and fixed structure of existing workpiece clamping devices, when dealing with metal workpieces of different sizes, it is usually necessary to disassemble and reinstall a suitable clamping mechanism. This process not only consumes a lot of time and labor costs, but also accelerates the wear of equipment parts due to frequent disassembly and installation, thereby shortening the service life of the equipment. If installation errors occur during reinstallation, it will also have an adverse effect on clamping accuracy and stability. Taking the small-batch, multi-variety production mode as an example, due to the frequent changes in workpiece size, the clamping device needs to be adjusted frequently, which not only leads to a significant decrease in production efficiency, but also significantly increases production costs. Therefore, a metal processing workpiece clamping device is proposed to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A metal processing workpiece clamping device includes a base, a platform mounted on the top of the base, a processing module mounted on the top of the platform, a clamping assembly disposed in the middle of the base, a mounting plate fixedly connected to the top of the base, and a conveying assembly disposed in the middle of the mounting plate.
[0008] The clamping assembly includes a mounting plate disposed inside the platform.

[0012] The top of the mounting plate is provided with a sliding groove, and the clamping block is slidably connected to the middle of the sliding groove.
[0013] As a further description of the above technical solution:
[0014] The rotating shaft is rotatably connected to the middle of the mounting plate, and both the first rotating rod and the second rotating rod are disposed between a pair of clamping blocks.
[0015] As a further description of the above technical solution:
[0016] The end of the second rotating rod away from the first rotating rod is rotatably connected to the side of the clamp block closest to the motor.

In small-batch, multi-variety production, this significantly saves adjustment time and improves production efficiency. Simultaneously, it reduces wear and tear on equipment components caused by frequent disassembly and reassembly, effectively extending the equipment's service life.
[0025] 2. In this utility model, the pusher block is pushed by the electric pusher rod, and together with the second protective pad and the guide plate, the processed workpiece is smoothly pushed to the collection box.

Detailed Implementation
[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Reference Figure 1 and Figure 2 An embodiment of this utility model is provided: a metal processing workpiece clamping device, including a base 1, a platform 2 mounted on the top of the base 1, a processing module 3 mounted on the top of the platform 2, a clamping component 4 provided in the middle of the base 1, an mounting block 14 fixedly connected to the top of the base 1, and a conveying component 13 provided in the middle of the mounting block 14.
[0033] The clamping assembly 4 includes a mounting plate 5, which is located inside the platform 2. A motor 7 is mounted on the bottom of the mounting plate 5, and a rotating shaft 8 is fixedly connected to the output end of the motor 7. A pair of clamping blocks 6 are slidably connected to the top of the mounting plate 5. A rotating rod 9 is fixedly connected to the outside of the rotating shaft 8. A rotating rod 10 is rotatably connected to the end of the rotating rod 9 away from the rotating shaft 8. A sliding groove 11 is provided on the top of the mounting plate 5. The clamping blocks 6 are slidably connected to the middle of the sliding groove 11. The rotating shaft 8 is rotatably connected to the middle of the mounting plate 5. The rotating rod 9 and the rotating rod 10 are both located between the pair of clamping blocks 6. A protective pad 12 is provided on the side of the clamping blocks 6 closest to the motor 7. The clamping assembly 4 is located directly below the processing module 3.
[0034] Specifically, by starting motor 7, the rotating shaft 8 is quickly driven to rotate. Rotating rod 9 is connected to the rotating shaft 8, so rotating rod 9 also rotates. Rotating rod 9 is rotatably connected to rotating rod 10. The rotation of rotating rod 9 causes rotating rod 10 to move. The other end of rotating rod 10 is rotatably connected to clamping block 6, and clamping block 6 has a sliding characteristic, so the movement of rotating rod 10 can push clamping block 6 to slide. As clamping block 6 slides, the two clamping blocks 6 gradually approach each other until the workpiece is clamped. A protective pad 12 is provided at the contact point between clamping block 6 and the workpiece. This effectively prevents the clamping block 6 from damaging the workpiece surface during clamping, improving the protection of the workpiece and ensuring the integrity and surface quality of the workpiece during processing.
[0035] Reference Figure 3 The conveying assembly 13 includes an electric push rod 15, which is located in the middle of the mounting block 14. A push block 16 is fixedly connected to the output end of the mounting block 14. A collection box 19 is installed on the side of the platform 2 away from the electric push rod 15. A pair of guide plates 18 are installed on the top of the platform 2. A protective pad 17 is provided on the side of the push block 16 away from the electric push rod 15.
[0036] Specifically, by activating the electric push rod 15, the push rod 15 can quickly push the block 16 forward in a predetermined direction. The part of the push block 16 that contacts the workpiece during the movement is equipped with a protective pad 17, which can effectively prevent the push block 16 from damaging the workpiece when pushing it, ensuring the integrity of the workpiece in the collection stage. The guide plate 18 guides the workpiece to move along a specific trajectory, so that the workpiece falls smoothly into the collection box 19, realizing the automation of workpiece collection, improving collection efficiency, and ensuring the quality of the workpiece through the cooperation of the protective pad 17 and the guide plate 18.
[0037] Reference Figure 2 The end of the rotating rod 10 away from the rotating rod 9 is rotatably connected to the side of the clamping block 6 near the motor 7, and the output end of the electric push rod 15 is adapted to the position of the collection box 19.
[0038] Specifically, by matching the position of the electric push rod 15 with the collection box 19, the push block 16 pushes the workpiece to the guide plate 18, and the metal workpiece quickly falls into the collection box 19, realizing automated collection operation and improving the collection efficiency of metal workpieces.
[0039] Working principle: When it is necessary to process a metal workpiece, first place the metal workpiece in the middle of the platform 2, start the motor 7, the motor 7 drives the rotating shaft 8 to rotate, and the rotating rod 9 rotates accordingly. The rotating rod 9 is rotatably connected to the rotating rod 10, which drives the rotating rod 10 to move. The other end of the rotating rod 10 is rotatably connected to the clamping block 6. Since the clamping block 6 can slide, the movement of the rotating rod 10 pushes the clamping block 6 to slide until the two clamping blocks 6 clamp the workpiece. The protective pad 12 can prevent the clamping block 6 from damaging the surface of the workpiece.
[0040] After the metal workpiece is clamped, the processing module 3 is started to process the workpiece. After the processing is completed, the electric push rod 15 is started. The electric push rod 15 pushes the push block 16 forward. The protective pad 17 can prevent the push block 16 from damaging the processed workpiece. The push block 16 pushes the processed workpiece and guides it to fall into the collection box 19 through the guide plate 18, thus completing the workpiece collection.
[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
