Description

Technical Field

[0001] This utility model relates to the field of mechanical gripper technology, specifically a detachable gripper for mechanical grippers. Background Technology

[0002] Robotic arms are crucial motion mechanisms in automated devices. Most existing robotic arms directly drive their gripping components using motors or cylinders, which presents the following problems:

[0003] First, when the robotic arm grasps a workpiece, the force point is on the claw arm, and the end of the claw arm is sharp, which may puncture the surface of the workpiece. Second, the claw arm will deform after being subjected to force for a long time, so it needs to be replaced or repaired in time. Third, it is difficult for a single type of claw arm to be used for workpieces of various shapes, so the claw head needs to be changed frequently to adapt to the workpiece. Therefore, a robotic arm that can easily change the claw head is needed to solve the problem. Summary of the Invention

[0004] (a) Problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a detachable chuck for mechanical grippers, which has the advantages of quick chuck replacement without puncturing the workpiece surface, thus solving the aforementioned problems.

[0006] To achieve the aforementioned goal of quickly changing the chuck without puncturing the workpiece surface, this utility model provides the following technical solution: a detachable chuck for a mechanical gripper, comprising a flange connecting seat, a chassis fixedly mounted on the bottom of the flange connecting seat, four interconnected cylinders detachably mounted on the bottom of the chassis, a push plate fixedly mounted on the output end of each cylinder, a drive arm fixedly mounted on the side of the push plate, a sleeve inserted at the other end of the drive arm, a vertical plate fixedly mounted on the side of the sleeve, a rubber pad fixedly mounted on the side of the vertical plate, a rubber block fixedly mounted on the side of the rubber pad, and a through hole opened inside the rubber block.

[0007] Preferably, the drive arm has an installation hole inside one end that is inserted into the sleeve. A middle plate is fixedly installed in the middle section of the installation hole. A spring is installed inside the installation hole. A T-shaped clip is installed at one end of the spring. A limit ring is fitted on the outside of the T-shaped clip. The limit ring is installed at the opening of the installation hole.

[0008] Preferably, the inner wall of the sleeve is provided with a slot corresponding to the T-shaped clamp, and the inner wall of the sleeve is provided with a guide groove that communicates with the slot.

[0009] Preferably, the drive arm is bent in shape, and the number of rubber blocks is arranged at equal intervals.

[0010] Preferably, one end of the spring presses against the side of the intermediate plate, and the other end of the spring presses against the side of the T-shaped clip.

[0011] Preferably, the sleeve is detachably engaged with the drive arm via a spring, a T-shaped clamp, and a groove.

[0012] Compared with the prior art, the present invention provides a detachable gripper for mechanical claws, which has the following advantages:

[0013] 1. This detachable gripper for mechanical claws allows for quick installation of the vertical plate, rubber pad, and rubber block by installing a sleeve on one end of the drive arm and sliding the T-shaped chuck inward along the guide groove until it inserts into the slot. Conversely, removing the sleeve allows the T-shaped chuck to slide outward along the guide groove, disengaging from the slot and enabling quick disassembly of the vertical plate, rubber pad, and rubber block. This process facilitates quick replacement and disassembly of deformed claw heads, as well as quick switching between different claw heads, thus adapting to various workpiece shapes.

[0014] 2. The detachable chuck for the mechanical gripper has a rubber pad installed on the side of the vertical plate. The side of the rubber pad has multiple rubber blocks. The cylinder output end retracts to drive the drive arm back to its original position. The drive arm contacts the workpiece using the rubber pad and rubber blocks. The rubber blocks have through holes inside to ensure that the rubber blocks can deform to fit the workpiece after the workpiece is subjected to force, thereby reducing the clamping wear on the workpiece surface.

[0021] In the description of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0022] Please see Figure 1-3 A detachable gripper for a mechanical claw includes a flange connector 1, the top of which has a threaded hole for easy connection to an external robotic arm; a chassis 2 is fixedly installed at the bottom of the flange connector 1, and four interconnected cylinders 3 are detachably installed at the bottom of the chassis 2, with a push plate 4 fixedly installed at the output end of the cylinders 3.

[0023] Please see Figure 1-3 A drive arm 5 is fixedly mounted on the side of the push plate 4. The drive arm 5 is bent in shape, and a sleeve 6 is inserted through the other end of the drive arm 5. A vertical plate 7 is fixedly mounted on the side of the sleeve 6, and a rubber pad 8 is fixedly mounted on the side of the vertical plate 7. Rubber round blocks 9 are fixedly mounted on the side of the rubber pad 8. The number of rubber round blocks 9 is several and arranged at equal intervals. A through hole 10 is opened inside the rubber round block 9. When the rubber round block 9 is squeezed by the workpiece, the rubber round block 9 can deform through the through hole 10, adapting to the shape of the workpiece and reducing wear on the surface of the workpiece.

[0024] Please see Figure 4 The drive arm 5, which is inserted into the sleeve 6, has a mounting hole 11 inside one end. A middle plate 12 is fixedly installed in the middle section of the mounting hole 11. A spring 13 is installed inside the mounting hole 11. A T-shaped clamp 14 is provided at one end of the spring 13. One end of the spring 13 presses against the side of the middle plate 12, and the other end of the spring 13 presses against the side of the T-shaped clamp 14. The tail end of the T-shaped clamp 14 is hemispherical, and a limit ring 15 is fitted on the outside of the T-shaped clamp 14. The limit ring 15 is installed at the opening of the mounting hole 11.

[0025] Please see Figure 4-5 The inner wall of the sleeve 6 is provided with a slot 16 corresponding to the T-shaped clamp 14, and the slot 16 is also semi-circular; the inner wall of the sleeve 6 is provided with a guide groove 17 that communicates with the slot 16; the T-shaped clamp 14 can slide along the guide groove 17 into the interior of the slot 16; the sleeve 6 is detachably engaged with the drive arm 5 by the spring 13, the T-shaped clamp 14 and the slot 16.

[0026] Working principle: When in use, by installing the sleeve 6 on one end of the drive arm 5, the T-shaped clamp 14 slides inward along the guide groove 17 until the T-shaped clamp 14 is inserted into the clamp groove 16, so that the vertical plate 7, rubber pad 8 and rubber block 9 can be quickly installed.

[0027] Conversely, when the sleeve 6 is pulled out, the T-shaped chuck 14 slides outward along the guide groove 17, and the T-shaped chuck 14 will leave the slot 16, so that the vertical plate 7, rubber pad 8 and rubber block 9 can be quickly disassembled; in the above process, the deformed claw head can be replaced and disassembled, and different claw heads can be quickly replaced, which indirectly affects the shape of the workpiece.

[0028] A rubber pad 8 is installed on the side of the vertical plate 7. The side of the rubber pad 8 has multiple rubber blocks 9. The cylinder 3 retracts at the output end to drive the drive arm 5 back to its original position. The drive arm 5 contacts the workpiece using the rubber pad 8 and the rubber blocks 9. The rubber blocks 9 have through holes 10 inside, which ensures that the rubber blocks 9 can deform to fit the workpiece after the workpiece is subjected to force, thereby reducing the clamping wear on the workpiece surface.

[0029] Conversely, when the output end of cylinder 3 opens, it causes the drive arm 5 to move outward, which in turn causes the vertical plate 7, rubber pad 8, and rubber block 9 to move outward, thus allowing the clamped workpiece to be lowered.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
