[0001] This utility model relates to the field of die casting part removal technology, and in particular to a quick-change clamp structure for a die casting part removal hand. Background Technology
[0002] The quick-change fixture structure for die-casting part pickers is a key tooling device in modern automated die-casting production lines. Its core function is to achieve rapid, precise, and safe connection and separation between the part picker and the robotic arm. This structure is not the part picker itself, but rather a "bridge" and "interface" connecting the part picker and the robotic end effector. It is a core component for improving production flexibility, ensuring equipment safety, and enhancing maintenance efficiency.
[0003] In the existing technology, the clamping structure of the die casting part picker usually needs to be replaced after long-term use. According to the content of Chinese utility model patent with patent publication number CN207139829U, the clamping structure of the device is generally replaced by multiple bolts, which takes a relatively long time and has low replacement efficiency, and urgently needs to be improved.
[0004] To address the aforementioned technical shortcomings, a solution is proposed that enables rapid replacement of the fixture structure without the need for a large number of bolts, resulting in higher replacement efficiency. Utility Model Content
[0005] The purpose of this invention is to provide a quick-change fixture structure for a die-casting part removal hand to solve the aforementioned problems.
[0006] The purpose of this utility model can be achieved through the following technical solution: a quick-change clamp structure for a die-casting part picker, including a clamp body, and a fixing plate disposed on one side of the clamp body. A cylinder is clamped on the other side of the fixing plate. A telescopic rod is installed on the cylinder. A connecting rod is fixedly connected to the end of the telescopic rod. A connecting plate is disposed inside the clamp body. The fixed plate has two sets of sliding grooves. An outer baffle is snapped onto the outside of the sliding groove. A movable rod extending to the outside of the fixed plate is provided inside the sliding groove. A lifting handle and a baffle are fixedly connected to both ends of the movable rod, respectively. A plug-in locking rod is fixedly connected to the baffle, and a return spring is sleeved on the movable rod. Two sets of connecting blocks are fixedly connected to one end of the fixture body, and the connecting blocks are provided with insertion holes.
[0007] Preferably, four sets of first shafts are fixedly connected to the connecting plate, a first connecting plate is movably connected to the first shaft, two sets of second shafts are fixedly connected to the first connecting plate, and a second connecting plate is movably connected to the second shaft.
[0008] Preferably, two sets of third shafts are fixedly connected to the second connecting plate, and the third shafts are movably connected to the fixture body, and a clamping block is fixedly connected to the end of the second connecting plate.
[0009] Preferably, the fixture body has a pressure plate inside, and each corner of the pressure plate is fixedly connected to a sliding plate. The fixture body has four sets of limiting slides through it, and the inner side of each limiting slide is engaged with a limiting rod, and a compression spring is sleeved on the limiting rod.
[0010] Preferably, the pressure plate is movably connected to the limiting rod, and the pressure plate is located inside the limiting slide.
[0011] Preferably, the end of the telescopic rod is fitted with the connecting plate, and the end of the connecting rod passes through the connecting plate and is threadedly connected to the nut.
[0012] Preferably, the two sets of connecting blocks are symmetrically arranged about the telescopic rod, and the plug-in rod is connected to the connecting blocks through the plug-in hole.
[0013] The beneficial effects of this utility model are: (1) First, pass the end of the connecting rod through the connecting plate and thread it with the nut so that the telescopic rod is securely connected to the connecting plate. Then, pull the handle outward to move the movable rod, thereby driving the baffle and the plug-in block to move together. Next, insert the connecting block into the inside of the slide groove and release the handle. At this time, under the elastic action of the return spring, the plug-in rod is inserted into the inside of the plug-in hole, thereby fixing the fixture body and the fixed plate. Conversely, the two can be separated, realizing the quick replacement function of the fixture structure. No need to use a large number of bolts, and the replacement efficiency is relatively higher. (2) The cylinder on the fixed plate drives the telescopic rod to retract, thereby driving the connecting plate to move. Then, with the cooperation of the first shaft, the first connecting plate will tilt and rotate. Then, under the restriction of the second shaft and the third shaft, the second connecting plate and the clamping block will rotate together until the casting is clamped. At this time, the elastic action of the compression spring pushes the sliding plate to move along the limit rod, thereby pushing the pressure plate to move until the pressure plate restricts the connecting plate. This can prevent the fixture structure from accidentally loosening after the casting is clamped, thus ensuring the clamping stability. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Example 1: The application background of this utility model is based on the long-term use of die casting part pickers, which usually requires the replacement of the clamping structure. The technical solution of this utility model is to solve the problem that the clamping structure of the existing device generally uses multiple bolts to connect and replace the part picker clamp, which takes a relatively long time and has low replacement efficiency. Please see Figures 1-5 As shown, this embodiment is a quick-change fixture structure for a die-casting part removal hand, including a fixture body 1, and a fixing plate 2 disposed on one side of the fixture body 1. A cylinder 3 is clamped on the other side of the fixing plate 2. A telescopic rod 4 is installed on the cylinder 3. A connecting rod 5 is fixedly connected to the end of the telescopic rod 4. A connecting plate 7 is disposed inside the fixture body 1. Two sets of sliding grooves 8 are opened on the fixing plate 2. An outer baffle 9 is clamped to the outside of the sliding grooves 8. A movable rod 10 extending to the outside of the fixing plate 2 is disposed in the sliding grooves 8. A lifting handle 11 and a baffle 12 are fixedly connected to both ends of the movable rod 10, respectively. A plug-in locking rod 13 is fixedly connected to the baffle 12. A return spring 14 is sleeved on the movable rod 10. Two sets of connecting blocks 15 are fixedly connected to one end of the fixture body 1. A plug-in locking hole 16 is opened through the connecting blocks 15. The end of the telescopic rod 4 is attached to the connecting plate 7, and the end of the connecting rod 5 passes through the connecting plate 7 and is threaded to the nut 6. The connection between the connecting rod 5 and the connecting plate 7, combined with the obstruction of the nut 6, allows the telescopic rod 4 to be connected to the connecting plate 7. Two sets of connecting blocks 15 are symmetrically arranged about the telescopic rod 4. The plug-in rod 13 is connected to the connecting block 15 through the plug-in hole 16. The clamp body 1 and the fixing plate 2 are engaged through the fitting connection of the plug-in rod 13 and the plug-in hole 16. Specifically, first, the end of the connecting rod 5 is passed through the connecting plate 7 and threaded with the nut 6, so that the telescopic rod is securely connected to the connecting plate 7. Then, the lifting handle 11 is pulled outward to move the movable rod 10, thereby driving the baffle 12 and the plug-in block to move together. Next, the connecting block 15 is inserted into the interior of the slide groove 8, and the lifting handle 11 is released. At this time, under the elastic action of the return spring 14, the plug-in rod 13 is inserted into the interior of the plug-in hole 16, thereby fixing the fixture body 1 and the fixing plate 2. Conversely, the two can be separated, realizing the function of quick disassembly and replacement of the fixture structure without the need for a large number of bolts, and the replacement efficiency is relatively higher.
[0018] Example 2: Please refer to Figures 1-5 As shown, this embodiment is a quick-change fixture structure for a die-casting part removal hand. Four sets of first shafts 17 are fixedly connected to the connecting plate 7. A first connecting plate 18 is movably connected to the first shaft 17. Two sets of second shafts 19 are fixedly connected to the first connecting plate 18. A second connecting plate 20 is movably connected to the second shaft 19. Two sets of third shafts 21 are fixedly connected to the second connecting plate 20, and the third shafts 21 are movably connected to the fixture body 1. A clamping block 22 is fixedly connected to the end of the second connecting plate 20. When the connecting plate 7 moves under the push of the telescopic rod 4, it will drive the first connecting plate 18 to tilt and rotate under the cooperation of the first shafts 17. Then, under the restriction of the second shafts 19 and the third shafts 21, it will drive the second connecting plate 20 and the clamping block 22 to rotate together. The clamp body 1 has a pressure plate 23 inside. Sliding plates 24 are fixedly connected to the corners of the pressure plate 23. Four sets of limiting slides 25 are opened through the clamp body 1. Limiting rods 26 are engaged inside the limiting slides 25. Compression springs 27 are sleeved on the limiting rods 26. The pressure plate 23 is movably connected to the limiting rods 26. The pressure plate 23 is located inside the limiting slides 25. The sliding plates 24 are movably connected to the limiting rods 26 so that the pressure plate 23 can be moved. Specifically, the cylinder 3 on the fixed plate 2 drives the telescopic rod 4 to retract, thereby moving the connecting plate 7. In turn, with the cooperation of the first shaft 17, the first connecting plate 18 tilts and rotates. Then, under the constraint of the second shaft 19 and the third shaft 21, the second connecting plate 20 and the clamping block 22 rotate together until the casting is clamped. At this time, the elastic action of the compression spring 27 pushes the sliding plate 24 to move along the limit rod 26, thereby pushing the pressure plate 23 to move until the pressure plate 23 restricts the connecting plate 7. This can prevent the fixture structure from accidentally loosening after the casting is clamped, thus ensuring clamping stability.
[0019] As can be seen from Embodiments 1 and 2, firstly, the end of the connecting rod 5 is passed through the connecting plate 7 and threadedly connected to the nut 6, so that the telescopic rod is securely connected to the connecting plate 7. Then, the lifting handle 11 is pulled outward, so that the movable rod 10 moves, thereby driving the baffle 12 and the plug-in block to move together. Next, the connecting block 15 is inserted into the interior of the slide groove 8, and the lifting handle 11 is released. At this time, under the elastic action of the return spring 14, the plug-in rod 13 is inserted into the interior of the plug-in hole 16, thereby fixing the fixture body 1 and the fixing plate 2. Conversely, the two can be separated, realizing the function of quick disassembly and replacement of the fixture structure without the need for a large number of bolts, and the replacement efficiency is relatively higher.
[0020] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
