Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figure 1-4A cylinder-driven chuck gripper includes a chuck 100, a sliding groove 101 on the chuck 100, a slider 102 slidably mounted in the sliding groove 101, a gripper 103 fixedly mounted on the slider 102, a cross mounting bracket 104 arranged on the chuck 100, two pairs of limiting rods 200 fixedly mounted on the side of the chuck 100, a movable disc 1 201 slidably mounted on one pair of limiting rods 200, and a movable disc 202 slidably mounted on the other pair of limiting rods 200, a drive rod 300 fixedly mounted on the bottom side of the movable disc 1 201, a drive cylinder 301 fixedly mounted at the end of the drive rod 1 300, and a gripper 103 fixedly mounted on the drive cylinder 1 301. The device is equipped with a mounting plate 302, on which a second drive cylinder 303 is fixedly mounted. A second drive rod 304 is fixedly mounted at the output end of the second drive cylinder 303. One end of the second drive rod 304 is fixedly mounted on a second movable plate 202. The two sets of cylinders, the first and second drive cylinders, serve as the power source, which limits the clamping force of the gripper and prevents excessive pressure on the tool. At the same time, the movement of the first and second movable plates is restricted by the limit rod to ensure the stability of the clamping movement. The driving force of the cylinder is converted into the driving force of the gripper movement by the L-shaped rotating rod, the transmission rod, the short connecting rod, and the long connecting rod, so that the gripper can grasp the workpiece with high precision.

[0020] The chuck 100 has a connecting groove 400, and the slider 102 has a slot 401. A mounting bracket 402 is fixedly installed on one side of the chuck 100, and an L-shaped rotating rod 403 is rotatably mounted on the mounting bracket 402. One end of the L-shaped rotating rod 403 is movably installed in the slot 401. The L-shaped rotating rod 403 rotates on the mounting bracket 402 via a rotating shaft 407, and one end of the L-shaped rotating rod 403 drives the slider 102 to slide within the slot 101 through the slot 401, thereby achieving the effect of controlling the grippers 103 to move closer or further apart.

[0021] A rotating shaft 407 is rotatably mounted on the L-shaped rotating rod 403, and the rotating shaft 407 is fixedly mounted on the slot 401. The L-shaped rotating rod 403 rotates on the mounting bracket 402 via the rotating shaft 407, thereby transmitting driving force.

[0022] A transmission rod 404 is fixedly installed on the first movable disk 201. A short connecting rod 405 is rotatably connected between the transmission rod 404 and the corresponding L-shaped rotating rod 403. A long connecting rod 408 is fixedly installed on the second movable disk 202. Similarly, a short connecting rod 405 is rotatably connected between the long connecting rod 408 and the corresponding L-shaped rotating rod 403. The first movable disk 201 and the second movable disk 202 respectively drive the transmission rod 404 and the long connecting rod 408 to move. The movable transmission rod 404 and the long connecting rod 408 drive the short connecting rod 405 to rotate via a transmission shaft 406. The rotating short connecting rod 405 drives the L-shaped rotating rod 403 to rotate via another transmission shaft 406.

[0023] Both ends of the short connecting rod 405 are rotatably mounted with drive shafts 406, and the two drive shafts 406 are respectively fixedly mounted on the L-shaped rotating rod 403 and the drive rod 404.

[0024] The end of the limiting rod 200, which is slidably connected to the first movable disk 201, passes through the second movable disk 202, and the limiting rod 200, which is slidably connected to the second movable disk 202, passes through the first movable disk 201. The output end of the second driving cylinder 303 drives the second movable disk 202 to move through the second driving rod 304. While the first movable disk 201 and the second movable disk 202 move synchronously, they are also restricted by the limiting rod 200 and can only move within a fixed range.

[0025] Working principle:

[0026] When using this device, drive cylinder 301 and drive cylinder 303 need to be started synchronously. The output end of drive cylinder 301 drives movable disc 201 to move via drive rod 300, and the output end of drive cylinder 303 drives movable disc 202 to move via drive rod 304. While movable discs 201 and 202 move synchronously, they are also restricted by limit rod 200 and can only move within a fixed range. Movable discs 201 and 202 respectively drive transmission rod 404 and long connecting rod. The connecting rod 408 is movable. The movable transmission rod 404 and the long connecting rod 408 drive the short connecting rod 405 to rotate via the transmission shaft 406. The rotating short connecting rod 405 drives the L-shaped rotating rod 403 to rotate via another transmission shaft 406. The L-shaped rotating rod 403 rotates on the mounting bracket 402 via the rotating shaft 407. One end of the L-shaped rotating rod 403 drives the slider 102 to slide in the slide groove 101 via the slot 401, thereby achieving the effect of controlling the grippers 103 to move closer or further apart to clamp the workpiece.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
