Description

Technical Field

[0001] This utility model relates to the field of mechanical automated grasping technology, specifically to a mechanical automated grasping device. Background Technology

[0002] Mechanical automation is the process of achieving automated control of machines or devices through mechanical means without human intervention. In the process of industrial automated production, automatic gripping devices are needed to achieve automatic gripping through automated control systems. However, existing mechanical gripping devices have relatively fixed gripping sizes when working, which cannot meet the gripping of items of various sizes, and the gripping height cannot be adjusted.

[0003] To address the aforementioned issues, "CN216377254U A Mechanical Automated Gripping Device" was disclosed. This device uses a motor to control the forward and reverse rotation of a threaded rod, adjusting the working height of the gripping mechanism. It utilizes the lever principle by incorporating an electric push rod, a hinged plate, a second connecting rod, and a first connecting rod to grip the product. However, several problems remain during use. For example, the gripping fixtures are often fixed or have a single opening / closing structure, typically only suitable for workpieces of specific shapes or sizes. When dealing with cylindrical workpieces of different diameters or curved contours, issues such as unstable gripping and uneven gripping force arise, easily causing workpiece slippage or surface damage. Furthermore, it cannot adapt to the diameter or outer surface curvature of the cylindrical workpiece. Additionally, the gripping device's fixtures are often fixed with bolts, making replacement time-consuming and labor-intensive. Utility Model Content

[0028] This application provides an automated mechanical gripping device, which will be described in detail below. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments.

[0029] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0030] Example 1

[0031] Please see Figure 1-10The mechanical automated gripping device provided in this embodiment includes: a mechanical arm column 1, a lifting groove 101 on one side of the mechanical arm column 1, a lifting plate 104 slidably connected inside the lifting groove 101, an equipment box 2 connected to one end of the lifting plate 104, two clamping rods 303 at the bottom of the equipment box 2, and a mounting plate 5 on one side of the clamping rods 303; a disassembly assembly disposed between the clamping rods 303 and the mounting plate 5, the disassembly assembly including: a mounting groove 304, a fixing block 305, an ejection groove 4, an ejection block 401 and a mounting block 501; and a gripping assembly disposed between the equipment box 2 and the mounting plate 5, the gripping assembly including: an electric push rod 3, a buffer groove 6, a buffer block 602 and a gripping block 603.

[0032] The gripping component can hold cylindrical workpieces of different diameters and can be adjusted according to the surface curvature of the workpiece. It also acts as a buffer to prevent damage to the workpiece due to excessive gripping force. Furthermore, the disassembly component allows for quick engagement and disassembly of the fixture using a snap-fit ​​structure. Compared to the traditional bolt fixing method, this method is more convenient and improves work efficiency.

[0033] Example 2

[0034] Based on Embodiment 1, a drive motor 102 is installed inside the robotic arm column 1, and a threaded rod 103 is connected to the top of the drive motor 102. A threaded hole that meshes with the threaded rod 103 is opened on the lifting plate 104.

[0035] The drive motor 102 drives the threaded rod 103 to rotate, which in turn drives the lifting plate 104 to move under the action of the threaded hole thread engagement, thereby changing the height of the equipment box 2 and the clamping rod 303 so that the clamping rod 303 can grasp the cylindrical workpiece. The bottom of the robotic arm column 1 is equipped with a rotating mechanism for rotating the robotic arm column 1.

[0036] Example 3

[0037] Based on Embodiment 1, a slot 201 is provided at the bottom of the equipment box 2, and the top of the clamping rod 303 extends into the equipment box 2 through the slot 201. A sliding rod 202 is connected inside the equipment box 2. A sliding hole 203 is provided on the clamping rod 303 to cooperate with the sliding rod 202, and a plurality of evenly distributed ball bearings 204 are provided on the inner wall of the sliding hole 203. An electric push rod 3 is installed on the top of the equipment box 2. A moving plate 301 is connected to the bottom of the electric push rod 3. Rotating rods 302 are rotatably connected to both sides of the moving plate 301. The end of the rotating rod 302 away from the moving plate 301 is rotatably connected to the top of the clamping rod 303.

[0038] When gripping a cylindrical workpiece, the clamping rods 303 are lowered to both sides of the workpiece, so that the gripping blocks 603 are located on both sides of the cylindrical workpiece. Then, the electric push rod 3 drives the moving plate 301 to move upward, so that the moving plate 301 drives one end of the rotating rod 302 to move upward, so that the other end of the rotating rod 302 drives the clamping rod 303 to move. The sliding rod 202 and the sliding hole 203 can limit the direction of movement of the clamping rod 303. The multiple balls 204 make the clamping rod 303 slide more smoothly on the sliding rod 202. The two clamping rods 303 move closer to each other, so that the gripping blocks 603 contact the cylindrical workpiece to perform the gripping operation.

[0039] The mounting plate 5 has multiple evenly distributed buffer grooves 6 on one side. Buffer springs 601 are connected inside the buffer grooves 6. Buffer blocks 602 are connected to one end of the buffer springs 601. One end of the buffer blocks 602 protrudes from the outer surface of the mounting plate 5 and is rotatably connected to gripping blocks 603. Rubber blocks 604 are connected between two adjacent gripping blocks 603 on the same side.

[0040] After the gripping block 603 contacts the cylindrical workpiece, the clamping rod 303 continues to move closer to the cylindrical workpiece. At this time, the gripping block 603 squeezes the buffer block 602, causing the buffer block 602 to retract into the buffer groove 6 and compressing the buffer spring 601. The buffer spring 601 then undergoes elastic deformation, generating a spring force, which reacts back onto the gripping block 603, causing the gripping block 603 to adhere tightly to the outer surface of the cylindrical workpiece. Because the gripping block 603 and the buffer block 602 are rotatably connected, multiple... Each gripping block 603 can rotate along the outer surface of the cylindrical workpiece and closely adhere to the outer surface of the cylindrical workpiece, thereby increasing the gripping area with the cylindrical workpiece and improving the gripping stability. On the other hand, through the setting of the buffer spring 601, in addition to providing external force for the gripping block 603, it also keeps the clamping rod 303 in an elastic contact state with the cylindrical workpiece, avoiding the clamping rod 303 being in a hard contact state with the cylindrical workpiece, and preventing the clamping force applied by the clamping rod 303 from being too large and causing damage to the cylindrical workpiece.

[0041] Then, by setting the rubber block 604, multiple gripping blocks 603 can be connected to each other when rotating, so that multiple gripping blocks 603 can form an arc structure, and can adapt to the diameter of the cylindrical workpiece to be gripped, thereby improving the applicability of gripping workpiece.

[0042] Example 4

[0043] Based on Embodiment 1, a mounting groove 304 is provided on one side of the clamping rod 303, and two limiting grooves 3041 communicating with the mounting groove 304 are provided on one side of the clamping rod 303, and the two limiting grooves 3041 are symmetrically arranged. A mounting block 501 that mates with the mounting groove 304 is fixedly connected to one side of the mounting plate 5. Two symmetrically arranged limiting blocks 502 are connected to the outside of the mounting block 501, and the limiting blocks 502 correspond to the positions of the limiting grooves 3041. A fixing block 305 is connected inside the mounting groove 304. A groove 503 is provided on the side to cooperate with the fixing block 305. Two symmetrically arranged slots 504 are provided on the inner wall of the groove 503, and the slots 504 and the limiting block 502 are on the same vertical plane. Two symmetrically arranged ejection slots 4 are provided on the outer side of the fixing block 305, and the ejection slots 4 and the limiting slots 3041 are on the same vertical plane. An ejection spring 402 is connected inside the ejection slot 4. One end of the ejection spring 402 is connected to an ejection block 401. One end of the ejection block 401 extends into the slot 504 and is provided with an inclined surface.

[0044] Furthermore, the fixed block 305 has a transmission groove 308 that communicates with the ejection groove 4. The clamping rod 303 is rotatably connected to a rotating rod 306. One end of the rotating rod 306 is located on the surface of the clamping rod 303 and is provided with a nut. The other end of the rotating rod 306 extends into the transmission groove 308 and is connected to a rotating gear 307. One side of the ejection block 401 is fixedly connected to a transmission rod 403 with an L-shaped structure. One side of the transmission rod 403 is provided with a meshing tooth. The transmission rod 403 meshes with the rotating gear 307 through the meshing tooth.

[0045] When disassembling or replacing the mounting plate 5, a tool can be used to rotate the nut on the rotating rod 306, thereby driving the rotating rod 306 and the rotating gear 307 to rotate. The rotating gear 307 meshes with the two transmission rods 403 through meshing teeth, so that the rotation of the rotating gear 307 drives the two transmission rods 403 to move closer to each other. Then, the transmission rods 403 drive the ejector block 401 to be retracted into the ejector groove 4, so that the ejector block 401 separates from the slot 504 and contacts the mounting block 501 to fix it. Then the mounting plate 5 can be moved outward, so that the mounting block 501 is detached from the mounting groove 304, and the disassembly of the mounting plate 5 is completed.

[0046] Then, when fixing the mounting plate 5 to the clamping rod 303 again, align the mounting block 501 on the mounting plate 5 with the mounting groove 304, and make the limiting block 502 on the mounting block 501 correspond to the limiting groove 3041 on the clamping rod 303. This ensures that the ejector block 401 corresponds to the slot 504 during the insertion of the mounting block 501, and also prevents the mounting block 501 and the mounting plate 5 from rotating.

[0047] Next, the mounting block 501 is inserted into the mounting groove 304, so that the fixing block 305 is inserted into the groove 503. During this process, the mounting block 501 contacts the inclined surface of the ejector block 401 and pushes the ejector block 401 into the ejector groove 4, so that the ejector spring 402 is compressed and accumulates elastic force. After the mounting block 501 is fully inserted into the mounting groove 304, the ejector block 401 corresponds to the position of the slot 504, so that the ejector block 401 is springed into the slot 504 under the action of the ejector spring 402, thus completing the locking and fixing of the mounting block 501, and thus completing the installation and fixing of the mounting plate 5.
