Description

Technical Field

[0001] This utility model relates to the field of gripper technology, and in particular to a synchronous dual gripper device. Background Technology

[0002] In industrial automation, gripper devices, as core components in material handling and assembly operations, directly impact production efficiency, workpiece machining accuracy, and equipment operational stability. As manufacturing moves towards greater flexibility and higher cycle times, traditional gripper devices are increasingly revealing limitations, failing to meet the demands of modern production. Specific issues include:

[0003] Low efficiency of single-station operation: Most of the existing mainstream grippers are single-set clamping structures, which can only perform gripping, handling or positioning operations on one workpiece at a time.

[0004] Poor synchronization of multiple grippers: In order to improve efficiency, some equipment uses multiple independently driven gripper assemblies. However, each gripper needs to be equipped with a separate motor, controller and transmission mechanism, which not only increases the size of the equipment and manufacturing cost, but also easily leads to asynchronous operation of multiple grippers due to drive signal delay and mechanical transmission error.

[0005] Therefore, it is necessary to propose a technical means to solve the above-mentioned defects. Utility Model Content

[0023] Please see Figures 1 to 4 A synchronous dual-jaw device includes a mounting plate 10 connected to an external moving device and a clamping assembly 20 mounted on the mounting plate 10 for clamping workpieces.

[0024] The clamping assembly 20 includes a first clamp 201, a second clamp 202, a third clamp 203, a fourth clamp 204, and a driving unit. The first clamp 201 and the second clamp 202 are mounted on the first side of the mounting plate 10 and are symmetrically arranged so that they clamp and fix the workpiece located on the first side of the mounting plate 10 when they are close to each other. The third clamp 203 and the fourth clamp 204 are mounted on the second side of the mounting plate 10 and are symmetrically arranged so that they clamp and fix the workpiece located on the second side of the mounting plate 10 when they are close to each other. The driving unit is connected to the first clamp 201, the second clamp 202, the third clamp 203, and the fourth clamp 204 and is used to drive the first clamp 201 and the second clamp 202 to move closer or further apart, and to drive the third clamp 203 and the fourth clamp 204 to move closer or further apart.

[0025] In one specific embodiment, the drive unit includes a first rotating shaft 205, a second rotating shaft 206, a third rotating shaft 207, a fourth rotating shaft 208, a first transmission wheel 209, a second transmission wheel 210, a third transmission wheel 211, a fourth transmission wheel 212, a first transmission belt 213, a second transmission belt 214, a first gear 215, a second gear 216, a first linkage 217, a second linkage 218, a third linkage 219, a fourth linkage 220, and a drive motor 221. The first rotating shaft 205, the second rotating shaft 206, the third rotating shaft 207, and the fourth rotating shaft 208 are rotatably mounted in the middle of the mounting plate 10 and are arranged sequentially along the length of the mounting plate 10. The first transmission wheel 209, the second transmission wheel 210, the third transmission wheel 211, and the fourth transmission wheel 212 are respectively mounted on the first rotating shaft 205, the second rotating shaft 206, the third rotating shaft 207, and the fourth rotating shaft 208. 7 and the fourth rotating shaft 208; the two ends of the first transmission belt 213 are respectively connected to the first transmission wheel 209 and the second transmission wheel 210; the two ends of the second transmission belt 214 are respectively connected to the third transmission wheel 211 and the fourth transmission wheel 212; the first gear 215 and the second gear 216 are respectively mounted on the second rotating shaft 206 and the third rotating shaft 207 and mesh with each other; the first linkage member 217 is connected to the first gripper 201 and the first side of the first transmission belt 213; the second linkage member 218 is connected to the second gripper 202 and the first side of the second transmission belt 214; the third linkage member 219 is connected to the third gripper 203 and the second side of the second transmission belt 214; the fourth linkage member 220 is connected to the fourth gripper 204 and the second side of the first transmission belt; the drive motor 221 is connected to the first rotating shaft 205 and is used to drive the first rotating shaft 205 to rotate. Specifically, in this embodiment, in conjunction with the attached... Figure 4The first transmission belt 213 is located between the first gripper 201 and the third gripper 203, and the second transmission belt 214 is located between the second gripper 202 and the fourth gripper 204. The first side of the first transmission belt 213 is the side closer to the first gripper 201, and the second side is the side closer to the third gripper 203. The first side of the second transmission belt 214 is the side closer to the second gripper 202, and the second side is the side closer to the fourth gripper 204. During operation, the drive motor 221 drives the first rotating shaft 205 to rotate, which in turn drives the second rotating shaft 206 to rotate through the first transmission wheel 209, the second transmission wheel 210, and the first transmission belt 213. This drives the first gear 215 mounted on the second rotating shaft 206 to rotate. Since the first gear 215 meshes with the second gear 216, it drives the third rotating shaft 207 to rotate, which in turn drives the third transmission wheel 211 to rotate, and then cooperates with the fourth transmission wheel 214. 12 and the fourth drive shaft cause the second drive wheel 210 to rotate, thereby causing the first drive belt 213 and the second drive belt 214 to rotate synchronously. Since the first linkage 217 is connected to the first jaw 201 and the first side of the first drive belt 213, and the second linkage 218 is connected to the second jaw 202 and the first side of the second drive belt 214, the first jaw 201 and the second jaw 202 can move closer to or away from the workpiece as needed when the first and second synchronous belts are synchronously reversed. Since the third linkage 219 is connected to the third jaw 203 and the second side of the second synchronous belt, and the fourth linkage 220 is connected to the fourth jaw 204 and the second side of the first drive belt 213, the third jaw 203 and the fourth jaw 204 can move closer to or away from the workpiece as needed when the first and second synchronous belts are synchronously reversed. Furthermore, the drive motor 221 is a servo motor with electromagnetic braking, which realizes self-locking function, has strong compatibility, low assembly difficulty, and fast electromagnetic braking response speed and high locking reliability.

[0026] In one specific embodiment, the driving unit further includes a first slide rail 222, a second slide rail 223, a first slider 224, a second slider 225, a third slider 226, and a fourth slider 227. The first slide rail 222 and the second slide rail 223 are respectively mounted on both sides of the mounting plate 10. The first slider 224 is slidably mounted on the first slide rail 222 and connected to the first gripper 201. The second slider 225 is slidably mounted on the first slide rail 222 and connected to the second gripper 202. The third slider 226 is slidably mounted on the second slide rail 223 and connected to the third gripper 203. The fourth slider 227 is slidably mounted on the second slide rail 223 and connected to the fourth gripper 204. Specifically, in this embodiment, the arrangement of the first slide rail 222, the second slide rail 223, the first slider 224, the second slider 225, the third slider 226, and the fourth slider 227 effectively ensures the directional movement of each gripper, thereby ensuring the stability of the structure.

[0027] In one specific embodiment, the mounting plate 10 is provided with a cover plate 30 for shielding the drive unit. In this embodiment, the cover plate 30 effectively shields the drive unit, improving the protection of the drive unit and the overall aesthetics of the device.

[0028] In one specific embodiment, the first gripper 201, the second gripper 202, the third gripper 203, and the fourth gripper 204 each include an arc-shaped clamping plate 228 for clamping the workpiece, an elastic telescopic column 229 connected to the arc-shaped clamping plate 228, and a connecting seat 230 for mounting the elastic telescopic column 229.

[0029] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
