Description

Technical Field

[0001] This invention relates to the field of die casting processing technology, and in particular to an anti-detachment die casting gripping device. Background Technology

[0002] Die castings are parts formed through a pressure casting process. The forming process is as follows: through pressure casting equipment equipped with casting molds, metal materials such as copper, zinc, aluminum or aluminum alloy heated to a molten state are injected into the feed port of the die casting machine. After being die-cast under high pressure, they are formed into copper, zinc, aluminum or aluminum alloy parts with the shape and size defined by the mold. These parts are collectively referred to as die castings. After the die casting is completed, it needs to be removed from the die casting mold with the help of a die casting gripping device.

[0003] Existing die casting gripping devices mostly use grippers with fixed angles or planar contact structures. Although they can quickly grip round or rectangular die castings, when gripping non-standard or irregularly shaped die castings, the contact area between the gripper and the workpiece is limited, stress is concentrated, and rigid clamping can easily cause the workpiece to dent or warp. Such defects result in a high scrap rate and significantly increase production costs. Therefore, an anti-detachment die casting gripping device is proposed. Summary of the Invention

[0004] To overcome the shortcomings of the prior art, the present invention provides an anti-detachment die-casting gripping device.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] A die-casting part gripping device with anti-detachment features a protective shell. The top of the protective shell is provided with a connecting part that is connected to an operating rod. The inside of the protective shell is also provided with two grippers for gripping the die-casting part. The inside of the protective shell is also provided with a clamping mechanism for controlling the opening and closing of the grippers.

[0007] The clamping mechanism includes a fixed frame fixed inside the protective shell, two extension plates fixed at the bottom of the fixed frame, a positioning plate fixed between the two extension plates, and two electric hydraulic rods arranged between the fixed frame and the positioning plate.

[0008] An angle adjustment mechanism is provided between the two electric hydraulic rods and the two grippers;

[0009] A spacing adjustment mechanism is also provided between the positioning plate and the gripper to drive the gripper to move.

[0010] As a preferred embodiment of the present invention, the angle adjustment mechanism includes a push block movably connected to the telescopic end of the electric hydraulic rod, a hinge rod fixed to the end of the push block away from the electric hydraulic rod, and the end of the hinge rod away from the push block rotatably connected to the top of the gripper.

[0011] Two transmission frames are also slidably installed on the outside of the positioning plate, and two limiting rods are fixed at the bottom of the two transmission frames. The end of the limiting rod away from the transmission frame is slidably connected to the gripper.

[0012] The gripper is also provided with a slot in the middle, and the end of the limiting rod away from the transmission frame is slidably installed inside the slot.

[0013] The slot is set in an obtuse angle, and two limiting rods are respectively set on the side of the two transmission frames near the two grippers. When the telescopic end of the electric hydraulic rod pushes the push block to move downward, the push block pushes the hinge rod to move downward, the hinge rod pushes the gripper to move downward, and the gripper moves downward, so that the limiting rod moves along the inside of the slot. Through the cooperation of the limiting rod and the slot, the gripper is limited. The gripper rotates around the bottom of the hinge rod, so that the gripper changes from a vertical state to an inclined state.

[0014] As a preferred technical solution of the present invention, the spacing adjustment mechanism includes a fixed shell fixed to the top of the positioning plate, an adjustment plate is rotatably installed inside the fixed shell, a bidirectional threaded rod is fixed in the middle of the adjustment plate, and a threaded hole adapted to the bidirectional threaded rod is opened on the top of the transmission frame.

[0015] Two insert rods are fixed on one side of the two push blocks facing each other, and a sleeve is provided between the two insert rods. The two ends of the sleeve are provided with insertion holes that are adapted to the insert rods.

[0016] Rotate the adjusting disc, which drives the bidirectional threaded rod to rotate. The bidirectional threaded rod cooperates with two transmission frames, causing the two transmission frames to move and adjust the distance between them. The transmission frames push the grippers to move through the limit rod, thus adjusting the distance between the two grippers.

[0017] As a preferred embodiment of the present invention, a side plate is slidably connected to the bottom of the extension plate, and the side of the side plate away from the extension plate is in contact with the end of the gripper close to the push block.

[0018] The upper half of the transmission frame is provided with a groove that matches the positioning plate, and the bottom of the extension plate is provided with a sliding groove that facilitates the movement of the side plate.

[0019] When the gripper moves, the gripper drives the push block to move via the hinge rod, and the push block drives the insertion rod to move, so that the insertion rod moves along the insertion hole of the sleeve. At the same time, the gripper pushes the side plate to move along the inside of the slide groove of the extension plate. The sleeve limits the push block, and the side plate limits the gripper to prevent the gripper from rotating when the spacing is adjusted.

[0020] As a preferred embodiment of the present invention, a main magnetic block is provided on one side of the two side plates facing each other, and a secondary magnetic block adapted to the main magnetic block is provided on the side of the gripper away from the limiting rod. By cooperating with the main magnetic block and the secondary magnetic block, the side plates and the gripper are magnetically connected, thereby preventing the side plates from separating from the extension plate due to gravity.

[0021] As a preferred embodiment of the present invention, the top of the push block is provided with a movable groove that is adapted to the telescopic end of the electro-hydraulic rod;

[0022] The telescopic end of the electric hydraulic rod is also fixed with a limiting plate, and the bottom of the moving groove is also provided with a limiting groove that matches the limiting plate.

[0023] The width of the limiting groove is greater than the width of the moving groove. When the push block moves, the moving groove and the limiting groove cooperate with the telescopic end of the electro-hydraulic rod and the limiting plate, so that the limiting plate and the telescopic end of the electro-hydraulic rod move along the inside of the moving groove and the limiting groove. The pushing block is limited by the cooperation of the limiting plate and the limiting groove, preventing the pushing block from separating from the electro-hydraulic rod when it moves.

[0024] As a preferred embodiment of the present invention, the bottom of the gripper is further provided with a swing arm, and the end of the swing arm away from the gripper is fixed with a suction cup for adsorbing the die-casting part.

[0025] The bottom of the gripper is provided with a through groove to facilitate the rotation of the swing arm, and the end of the swing arm away from the suction cup is provided with a connecting shaft to drive the swing arm to rotate;

[0026] The connecting shaft is rotatably installed inside the through groove, and the end of the swing arm away from the connecting shaft extends to the outside of the through groove. Both ends of the connecting shaft extend to the outside of the gripper. Rotating the connecting shaft causes the swing arm to rotate, which in turn causes the suction cup to rotate, thus changing the suction cup from a horizontal state to a vertical state.

[0027] As a preferred technical solution of the present invention, a shielding plate is also fixed on the outer wall of the connecting shaft, a connecting block is also fixed on the side of the shielding plate away from the connecting shaft, a locking rod is hinged in the middle of the connecting block, and a hand-held plate is also fixed on the side of the locking rod away from the connecting block.

[0028] Two locking blocks are also fixed to the side of the gripper, and each locking block has a limiting groove in the middle that matches the locking rod.

[0029] Pull the hand plate to separate it from the locking block. Rotate the hand plate horizontally by 90 degrees. Then, rotate the hand plate by 90 degrees. The hand plate will cause the connecting block to rotate by 90 degrees. The connecting block will cause the blocking plate to rotate by 90 degrees. The blocking plate will cause the connecting shaft to rotate by 90 degrees. The connecting shaft will then cause the suction cup to rotate by 90 degrees via the swing rod.

[0030] Compared with the prior art, the beneficial effects that this invention can achieve are:

[0031] 1. This invention utilizes the cooperation of a clamping mechanism, an angle adjustment mechanism, grippers, an electro-hydraulic rod, a transmission frame, a limit rod, a push block, a hinge rod, and a slot to drive the grippers to swing around the bottom of the hinge rod, thereby maximizing the contact area between the gripper contact surface and the workpiece surface. This effectively disperses clamping stress, prevents workpiece denting and warping deformation, reduces product defect rate, and significantly reduces production costs.

[0032] 2. This invention achieves precise and convenient adjustment of the gripper spacing through the cooperation of a spacing adjustment mechanism, a bidirectional threaded rod, an adjustment disc, a transmission frame, a sleeve, and a plug rod. It can flexibly adapt to regular, non-standard, or irregular die-cast parts of different sizes. There is no need to disassemble the entire device. The changeover can be completed manually or automatically, which greatly shortens downtime and improves equipment utilization.

[0033] 3. The present invention uses the cooperation of structures such as push block, sleeve, insert rod, side plate and gripper to limit the gripper and prevent the gripper from deflecting or tilting during adjustment. This ensures that the contact surface of the gripper is always accurately aligned with the contour of the workpiece, and avoids false clamping or misalignment caused by the rotation of the gripper.

[0034] 4. This invention, through the cooperation of structures such as electric hydraulic rod, push block, limit plate, sleeve and insert rod, prevents the push block from deflecting or twisting when moving laterally, ensures that the stroke and force output of the drive gripper are uniform and stable, disperses the torque impact generated by the deflection of the push block, and reduces the wear of the connection between the electric hydraulic rod and the push block.

[0035] 5. This invention adjusts the angle of the suction cup by coordinating the connecting shaft, swing arm, hand plate, locking rod and connecting block, so that the suction cup fits the curved or inclined surface of the die-cast part, avoiding vacuum leakage of the suction cup and improving the suction force of the suction cup.

[0036] 6. This invention achieves 90-degree rotation and precise positioning of the suction cup through the cooperation of structures such as connecting shaft, swing rod, shielding plate, hand-held plate, locking rod, connecting block and locking block. It can both horizontally adsorb flat die-cast parts and vertically adsorb vertical irregular parts, thus improving the practicality of the device. Attached Figure Description

[0050] To make the technical means, creative features, and achieved objectives and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0051] Example: The present invention provides, as follows Figure 1 and Figure 2 The device shown is a die-casting part gripping device for preventing detachment. It includes a protective shell 1, a connecting part 2 connected to the operating rod on the top of the protective shell 1, and two grippers 3 for gripping the die-casting part inside the protective shell 1.

[0052] As can be seen from the above, when in use, the connecting part 2 is connected to the operating lever, and the connecting part 2 is moved by the operating lever. The connecting part 2 moves the protective shell 1, and the protective shell 1 moves the gripper 3, so that the gripper 3 enters the interior of the die-casting part. The die-casting part is picked up and put down by the gripper 3.

[0053] refer to Figure 2 , Figure 3 and Figure 4 As shown, the inside of the protective shell 1 is also provided with a clamping mechanism 4 for controlling the opening and closing of the gripper 3;

[0054] The clamping mechanism 4 includes a fixed frame 401 fixed inside the protective shell 1. Two extension plates 403 are fixed at the bottom of the fixed frame 401. A positioning plate 404 is fixed between the two extension plates 403. Two electric hydraulic rods 402 are provided between the fixed frame 401 and the positioning plate 404.

[0055] An angle adjustment mechanism is provided between the two electric hydraulic rods 402 and the two grippers 3;

[0056] A spacing adjustment mechanism is also provided between the positioning plate 404 and the gripper 3 to drive the gripper 3 to move.

[0057] refer to Figure 5 and Figure 6 As shown, the angle adjustment mechanism includes a push block 409 movably connected to the telescopic end of the electric hydraulic rod 402. A hinge rod 410 is fixed to one end of the push block 409 away from the electric hydraulic rod 402. The end of the hinge rod 410 away from the push block 409 is rotatably connected to the top of the gripper 3.

[0058] Two transmission frames 406 are also slidably installed on the outside of the positioning plate 404. Two limiting rods 407 are also fixed at the bottom of the two transmission frames 406. The end of the limiting rod 407 away from the transmission frame 406 is slidably connected to the gripper 3.

[0059] The gripper 3 also has a slot 413 in the middle, and the end of the limiting rod 407 away from the transmission frame 406 is slidably installed inside the slot 413.

[0060] The slot 413 is set in an obtuse angle, and the two limiting rods 407 are respectively set on the side of the two transmission frames 406 near the two grippers 3. When the telescopic end of the electric hydraulic rod 402 pushes the push block 409 to move downward, the push block 409 pushes the hinge rod 410 to move downward, the hinge rod 410 pushes the gripper 3 to move downward, and the gripper 3 moves downward, so that the limiting rod 407 moves along the inside of the slot 413. Through the cooperation of the limiting rod 407 and the slot 413, the gripper 3 is limited. The gripper 3 rotates around the bottom of the hinge rod 410, so that the gripper 3 changes from a vertical state to an inclined state.

[0061] The telescopic end of the electric hydraulic rod 402 pushes the push block 409 downward, the push block 409 pushes the hinge rod 410 downward, the hinge rod 410 pushes the gripper 3 downward, and the gripper 3 downward causes the limiting rod 407 to move along the inside of the slot 413. Through the cooperation of the limiting rod 407 and the slot 413, the gripper 3 is limited. The gripper 3 rotates around the bottom of the hinge rod 410, so that the gripper 3 changes from a vertical state to an inclined state. This makes the contact surface of the inclined gripper 3 form the maximum contact area with the workpiece surface, effectively dispersing the clamping stress. By adjusting the angle, it can adapt to workpieces with different curvatures and curved surfaces or complex structural parts with deep cavities and bosses. When changing models, only parameters need to be adjusted to complete the adaptation, shortening the time to change the gripper 3 and greatly improving the flexible production capacity of the production line.

[0062] refer to Figure 7 , Figure 8 and Figure 9 As shown, the spacing adjustment mechanism includes a fixed shell 414 fixed to the top of the positioning plate 404, an adjustment plate 412 is rotatably installed inside the fixed shell 414, a bidirectional threaded rod 411 is fixed in the middle of the adjustment plate 412, and a threaded hole adapted to the bidirectional threaded rod 411 is opened on the top of the transmission frame 406.

[0063] Two insert rods 416 are fixed on one side of the two push blocks 409 facing each other. A sleeve 415 is provided between the two insert rods 416. Insertion holes that are compatible with the insert rods 416 are opened at both ends of the sleeve 415.

[0064] Rotate the adjusting disc 412, which drives the bidirectional threaded rod 411 to rotate. The bidirectional threaded rod 411 cooperates with the two transmission frames 406 to move the two transmission frames 406 and adjust the distance between the two transmission frames 406. The transmission frames 406 push the grippers 3 to move through the limiting rod 407, thereby adjusting the distance between the two grippers 3.

[0065] refer to Figure 7 , Figure 8 and Figure 9As shown, a side plate 405 is also slidably connected to the bottom of the extension plate 403, and the side of the side plate 405 away from the extension plate 403 is in contact with the end of the gripper 3 near the push block 409.

[0066] The upper half of the transmission frame 406 is provided with a groove that matches the positioning plate 404, and the bottom of the extension plate 403 is provided with a sliding groove that facilitates the movement of the side plate 405.

[0067] When the gripper 3 moves, the gripper 3 drives the push block 409 to move via the hinge rod 410. The push block 409 drives the insertion rod 416 to move, so that the insertion rod 416 moves along the insertion hole of the sleeve 415. At the same time, the gripper 3 pushes the side plate 405 to move along the inside of the groove of the extension plate 403. The sleeve 415 limits the push block 409, and the side plate 405 limits the gripper 3 to prevent the gripper 3 from rotating when the spacing is adjusted.

[0068] refer to Figure 7 , Figure 8 and Figure 9 As shown, a main magnetic block 425 is provided on the side of the two side plates 405 facing each other, and a secondary magnetic block 426 adapted to the main magnetic block 425 is provided on the side of the gripper 3 away from the limiting rod 407. The main magnetic block 425 and the secondary magnetic block 426 cooperate to make the side plate 405 and the gripper 3 magnetically connected, thereby preventing the side plate 405 from separating from the extension plate 403 due to gravity.

[0069] refer to Figure 8 , Figure 9 and Figure 10 As shown, the top of the push block 409 is provided with a moving groove that is adapted to the telescopic end of the electric hydraulic rod 402;

[0070] The telescopic end of the electric hydraulic rod 402 is also fixed with a limit plate 417, and the bottom of the moving groove is also provided with a limit groove that matches the limit plate 417.

[0071] The width of the limiting groove is greater than the width of the moving groove. When the push block 409 moves, the moving groove and the limiting groove cooperate with the telescopic end of the electro-hydraulic rod 402 and the limiting plate 417, so that the limiting plate 417 and the telescopic end of the electro-hydraulic rod 402 move along the inside of the moving groove and the limiting groove. The limiting plate 417 cooperates with the limiting groove to limit the push block 409 and prevent the push block 409 from separating from the electro-hydraulic rod 402 when moving.

[0072] refer to Figure 11 and Figure 12 As shown, a swing arm 419 is also provided at the bottom of the gripper 3, and a suction cup 408 for adsorbing the die-casting part is fixed at the end of the swing arm 419 away from the gripper 3.

[0073] The bottom of the gripper 3 is provided with a through groove to facilitate the rotation of the swing arm 419. The end of the swing arm 419 away from the suction cup 408 is provided with a connecting shaft 418 to drive the swing arm 419 to rotate.

[0074] The connecting shaft 418 is rotatably installed inside the through groove, and the end of the rocker arm 419 away from the connecting shaft 418 extends to the outside of the through groove. Both ends of the connecting shaft 418 extend to the outside of the gripper 3. When the connecting shaft 418 is rotated, the connecting shaft 418 drives the rocker arm 419 to rotate, and the rocker arm 419 drives the suction cup 408 to rotate, so that the rocker arm 419 drives the suction cup 408 from a horizontal state to a vertical state.

[0075] refer to Figure 11 and Figure 12 As shown, a shielding plate 420 is also fixed to the outer wall of the connecting shaft 418. A connecting block 423 is also fixed to the side of the shielding plate 420 away from the connecting shaft 418. A locking rod 422 is hinged to the middle of the connecting block 423. A hand plate 421 is also fixed to the side of the locking rod 422 away from the connecting block 423.

[0076] Two locking blocks 424 are also fixed to the side of the gripper 3. Each locking block 424 has a limiting groove in the middle that matches the locking rod 422.

[0077] Pull the hand plate 421 to separate it from the locking block 424. Rotate the hand plate 421 horizontally by 90 degrees. Rotate the hand plate 421 by 90 degrees. The hand plate 421 drives the connecting block 423 to rotate by 90 degrees. The connecting block 423 drives the blocking plate 420 to rotate by 90 degrees. The blocking plate 420 drives the connecting shaft 418 to rotate by 90 degrees. The connecting shaft 418 drives the suction cup 408 to rotate by 90 degrees through the swing rod 419.

[0078] Working principle:

[0079] refer to Figures 1-12 As shown, pull the hand plate 421 to separate the hand plate 421 from the locking block 424, rotate the hand plate 421 horizontally by 90 degrees, and rotate the hand plate 421 by 90 degrees. The hand plate 421 drives the connecting block 423 to rotate by 90 degrees, the connecting block 423 drives the blocking plate 420 to rotate by 90 degrees, the blocking plate 420 drives the connecting shaft 418 to rotate by 90 degrees, and the connecting shaft 418 drives the suction cup 408 to rotate by 90 degrees through the swing rod 419, thus adjusting the direction of the suction cup 408.

[0080] The rotating adjustment disc 412 drives the bidirectional threaded rod 411 to rotate. The bidirectional threaded rod 411 cooperates with the two transmission frames 406 to move the two transmission frames 406 and adjust the distance between the two transmission frames 406. The transmission frames 406 push the gripper 3 to move through the limiting rod 407 to adjust the distance between the two grippers 3. The gripper 3 drives the push block 409 to move through the hinge rod 410. The push block 409 drives the insertion rod 416 to move, so that the insertion rod 416 moves along the insertion hole of the sleeve 415. At the same time, the gripper 3 pushes the side plate 405 to move along the inside of the slide groove of the extension plate 403. The sleeve 415 limits the push block 409, and the side plate 405 limits the gripper 3 to prevent the gripper 3 from rotating when adjusting the distance. The gripper 3 can only move laterally back and forth when adjusting the distance.

[0081] When the telescopic end of the electric hydraulic rod 402 pushes the push block 409 downward, the push block 409 pushes the hinge rod 410 downward, the hinge rod 410 pushes the gripper 3 downward, and the gripper 3 downward causes the limiting rod 407 to move along the inside of the slot 413. Through the cooperation of the limiting rod 407 and the slot 413, the gripper 3 is limited. The gripper 3 rotates around the bottom of the hinge rod 410, so that the gripper 3 changes from a vertical state to an inclined state. The gripper 3 and the suction cup 408 grip the die-casting part that needs to be gripped.

[0082] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
