Detailed Implementation

[0018] The present invention will be further described in detail below with reference to the accompanying drawings.

[0019] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive element, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0020] This embodiment relates to a workpiece side punching clamping device, referring to... Figures 1-3The system includes: a mold table 100, a drive component 200, a linkage component 300, and a pressing component 400. The mold table 100 has a positioning protrusion 110 for placing a workpiece 600. The drive component 200 is mounted on the mold table 100 and located near the positioning protrusion 110. One end of the linkage component 300 is connected to the output shaft 210 of the drive component 200. The pressing component 400 is mounted on the end of the linkage component 300 away from the drive component 200. Under the action of the drive component 200, the linkage component 300 drives the pressing component 400 to move towards the mold table 100 to press the workpiece 600 or to move away from the mold table 100 to release the workpiece 600. Specifically, in this embodiment, the drive component 200 is a cylinder. After workpiece 600 is placed on positioning protrusion 110, drive component 200, i.e., the output shaft 210 of cylinder, extends outward. Linkage component 300 drives pressing component 400 towards mold table 100, i.e., towards positioning protrusion 110, pressing component 400 to press workpiece 600 firmly onto positioning protrusion 110. After the side punching of workpiece 600 is completed, drive component 200, i.e., the output shaft 210 of cylinder, resets. Linkage component 300 drives pressing component 400 away from mold table 100, i.e., away from positioning protrusion 110, pressing component 400 releases workpiece 600 so that operator can remove workpiece 600 for the next production step. Compared to traditional manual support and pressing methods, this workpiece side-punching clamping device, through the driving force of the drive component 200 and the linkage of the linkage component 300, enables the pressing component 400 to press or release the workpiece 600, thus improving the overall production process safety and significantly increasing production efficiency. It also avoids the problem of inaccurate workpiece 600 positioning caused by slight hand movements of the operator, ensuring the accuracy of workpiece 600 positioning and consequently guaranteeing the consistency of punching quality for workpieces 600 in the same batch. In some embodiments, the drive component 200 can also be an electric cylinder.

[0021] Furthermore, two of each of the driving component 200, linkage component 300, and pressing component 400 are symmetrically arranged on the left and right sides of the positioning protrusion 110 to position the workpiece 600 on both sides and prevent it from tilting to one side. The output shaft 210 and linkage component 300 are inclined toward the top of the positioning protrusion 110. Specifically, the pressing component 400 is positioned at the top of the positioning protrusion 110. When the workpiece 600 is placed on the positioning protrusion 110, the external stamping die stamps the top side of the workpiece 600, generating a downward pressure on the top side. The output shaft 210 and linkage component 300 are inclined toward the top of the positioning protrusion 110, and the pressing component 400 presses the top of the workpiece 600 to prevent it from shifting and to enhance the positioning effect.

[0022] In this embodiment, refer to Figures 4-7The linkage component 300 includes: a fixing component 310, a first connecting component 320, a clamping component 330, and a second connecting component 340. The fixing component 310 is located on the side of the mold table 100 where the positioning protrusion 110 is provided; the fixing component 310 has two extension portions 311 that are spaced vertically apart and extend towards the output shaft 210. Two first connecting components 320 are provided; one end of each first connecting component 320 is rotatably connected to the output shaft 210, and the other end is rotatably connected to the extension portion 311. One end of the clamping component 330 is located between the two extension portions 311 and is rotatably connected to each of the two extension portions 311; the other end of the clamping component 330 is used for assembly of the pressing component 400. The second connector 340 has two connecting portions 341 arranged vertically at intervals; the free end of the output shaft 210 is located between the two connecting portions 341; the two connecting portions 341 are located between the two first connectors 320; one end of each connecting portion 341 is rotatably connected to the output shaft 210, and the other end is rotatably connected to the end of the clamping member 330 near the extension 311; the end of the clamping member 330 near the extension 311 is located between the other ends of the two connecting portions 341. Specifically, the two extensions 311 are connected by an arc-shaped connecting plate. The two connecting portions 341 are also connected by an arc-shaped connecting plate. When the workpiece 600 is placed on the positioning protrusion 110, the output shaft 210 of the driving member 200 (i.e., the cylinder) extends outward. The output shaft 210 drives the first connecting member 320 and the second connecting member 340, which are rotatably connected to the output shaft 210, to rotate. This, in turn, drives the end of the clamping member 330 equipped with the pressing member 400 to move towards the mold table 100. The pressing member 400 then moves towards the positioning protrusion 110 to press the workpiece 600 towards the positioning protrusion 110. After the side punching of the workpiece 600 is completed, the output shaft 210 of the driving member 200 (i.e., the cylinder) resets. The output shaft 210 drives the end of the first connecting member 320 and the second connecting member 340, which are rotatably connected to the output shaft 210, to rotate. This, in turn, drives the end of the clamping member 330 equipped with the pressing member 400 to move away from the mold table 100. The pressing member 400 then moves away from the positioning protrusion 110 to release the workpiece 600. The driving action of the driving component 200 and the high linkage between the fixing component 310, the first connecting component 320, the clamping component 330 and the second connecting component 340 make the overall pressing and releasing of the workpiece 600 simple and quick.

[0023] Furthermore, two of each of the fixing member 310, the first connecting member 320, the clamping member 330, and the second connecting member 340 are provided and arranged symmetrically. The clamping member 330 has a through hole 331; one end of the pressing member 400 passes through the through hole 331 and is detachably engaged with the clamping member 330 so as to replace the pressing member 400.

[0024] Furthermore, referring to Figure 6 as well as Figure 7 The pressing component 400 includes a pressing head 410 and a pressing post 420. The pressing head 410 is used to press the workpiece 600. One end of the pressing post 420 is fixedly disposed with the pressing head 410, and the other end passes through a through hole 331 and is detachably engaged with the clamping component 330. The side of the pressing head 410 that contacts the workpiece 600 is provided with a soft coating to avoid scratching the workpiece 600. The pressing head 410 can also be made of a soft material, such as a silicone pressing head or a rubber pressing head. In this embodiment, the pressing post 420 and the clamping component 330 are threaded together. In some embodiments, the pressing post 420 and the clamping component 330 can also be snap-fitted together.

[0025] In some embodiments, refer to Figures 4-7 The workpiece side punching clamping device further includes: a mounting plate 510 with a first side 511 and a second side 512 opposite to the first side 511, a first extension plate 520, and a second extension plate 530. The mounting plate 510 is mounted on the mold table 100 and located on the side near the positioning protrusion 110. One end of the first extension plate 520 is fixedly connected to the first side 511, and its free end extends away from the mold table 100. One end of the second extension plate 530 is fixedly connected to the second side 512, and its free end extends away from the mold table 100. One side of the linkage 300 is mounted on the side of the mounting plate 510 facing away from the mold table 100 and is located between the first extension plate 520 and the second extension plate 530. The driving member 200 is mounted on the free ends of the first extension plate 520 and the second extension plate 530. Specifically, the first side 511 of the mounting plate 510 is its top side, and the second side 512 of the mounting plate 510 is its bottom side. The mounting plate 510 and the mounting surface on the mold table 100 for mounting the mounting plate 510 are inclined to facilitate the inclined arrangement of the drive component 200 and the linkage component 300. The mounting plate 510, the first extension plate 520, and the second extension plate 530 are arranged to provide the workpiece 600 with the space to be placed on or removed from the positioning protrusion 110. Furthermore, the mounting plate 510, the first extension plate 520, and the second extension plate 530 are integrally formed to provide assembly efficiency and structural stability. In addition, there are two symmetrically arranged mounting plates 510, the first extension plate 520, and the second extension plate 530, located on the left and right sides of the positioning protrusion 110, to accommodate the two drive components 200 and the two linkage components 300.
