Description

Technical Field

[0001] This utility model relates to a clamping device for a forging manipulator, specifically an adjustable clamping device for a forging manipulator, belonging to the technical field of forging manipulators. Background Technology

[0002] Forging manipulators are essential large-scale auxiliary machines in forging workshops for forging red-hot billets. They replace manual labor in clamping and manipulating large, high-temperature forgings, avoiding direct contact between workers and high-temperature billets, reducing labor intensity and safety risks. The clamping and manipulating of forgings can be controlled by clamping devices.

[0003] In the prior art, such as the clamping device of a forging manipulator disclosed in CN212598654U, by setting a sliding groove, adjusting slider, first threaded hole, adjusting seat, and movable clamping plate, the clamping size can be arbitrarily adjusted according to different workpieces. The adjusted clamp is effectively fixed by using the second threaded hole, mounting column, connecting rope, operating bar, and threaded positioning bar, thereby completing the position fixation of the forging workpiece, facilitating people's forging work, and greatly improving the applicability of the clamping device.

[0004] However, in implementing the relevant technology, the clamping device of the forging manipulator designed above has the following problems: Although the existing technology can clamp and position the forging workpiece by adjusting the cooperation of components such as the slider, in actual use, the forging workpiece may have irregular or irregular shapes. By clamping and fixing it directly, some parts may not be clamped sufficiently, which will affect the effect of subsequent forging. In view of this, an adjustable clamping device for forging manipulator is provided to overcome the above defects. Utility Model Content

[0005] This invention addresses the technical problem that forging workpieces may have irregular or non-standard shapes, and that direct clamping may result in some parts not being fully clamped, thus affecting the subsequent forging effect. Therefore, this invention provides an adjustable clamping device for forging manipulators.

[0006] The present invention achieves the above objectives through the following technical solution: an adjustable clamping device for a forging manipulator, comprising a support platform, wherein a groove is provided at the top of the support platform and a clamping mechanism is provided inside the groove;

[0007] The clamping mechanism includes a motor, which is embedded in one side of the outer wall of the support platform. A worm gear is fixedly installed at the power output end of the motor. One end of the worm gear that passes through the support platform is rotatably connected to a worm wheel. A bidirectional threaded rod extends out from the inside of the worm wheel. A slider is slidably connected to the outer wall of the end of the bidirectional threaded rod that passes through the slide groove. A connecting rod is rotatably connected to the top of the slider. A clamping plate is rotatably connected to the top of the connecting rod.

[0008] As a further improvement of this utility model: a connecting ring is fixedly installed on one side of the outer wall of the clamping plate, and a bearing block is rotatably connected to one axial end of the connecting ring.

[0009] As a further embodiment of this utility model: the bidirectional threaded rod is threadedly connected to the slider, and the slider forms a rotating structure with the clamping plate through the connecting rod.

[0010] As a further improvement of this utility model: a fixing block is fixedly installed on one side of the top slide groove of the support platform, and a limit mechanism is provided on one side of the fixing block.

[0011] As a further embodiment of this utility model: the limiting mechanism includes a connecting rod, which is fixed to one side of the outer wall of the connecting rod, and an insertion plate is fixed to the end of the connecting rod away from the connecting rod, and a support shaft is rotatably connected inside the insertion plate.

[0012] As a further embodiment of this utility model: a hydraulic rod is embedded in the outer wall of the fixing block, and an abutment plate is fixedly installed at the power output end of the hydraulic rod. A slot is provided on the outer wall of the abutment plate at the position corresponding to the support shaft.

[0013] As a further embodiment of this utility model: the insertion plate and the support shaft form a rotating structure, and the support shaft and the slot form a sliding structure.

[0014] The beneficial effects of this utility model are as follows: First, after the forging workpiece is placed on the support platform, the motor drives the worm gear transmission, which in turn drives two bidirectional threaded rods to drive two corresponding sliders. The clamping plates clamp the forging workpiece through the connecting rod. It should be noted that several clamping plates are set up and are connected to each other by connecting rings and support blocks. When the connecting rods and sliders are connected to each other by rotation, they can fit the irregular shape of the forging workpiece. After automatically adjusting the angle according to the forging workpiece, they can fully fit and limit the positioning and clamping effect, thus making it suitable for forging workpieces with irregular or non-standard shapes and improving the overall applicability and comprehensiveness of the clamping device.

[0015] Driven by the slider and connecting rod, the connecting rod slides and rotates into the slot via the insertion plate and support shaft. Simultaneously, the connecting rod drives the connecting rod to rotate and connect with the slider and clamping plate, thus avoiding limit situations. This allows the abutment plate to abut against one side of the forging workpiece, providing initial limitation. Subsequently, the hydraulic rod embedded in the fixing block extends, pushing the abutment plate to further increase the abutment force, preventing loosening. It provides limiting clamping on both sides where clamping plates are not installed, improving the stability of forging workpiece positioning. It is also suitable for clamping and positioning irregular or shaped forging workpieces from both sides. Attached Figure Description

[0022] 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. Example 1

[0023] like Figures 1 to 5As shown, an adjustable clamping device for a forging manipulator includes a support platform 1. A groove 2 is formed at the top of the support platform 1, and a clamping mechanism 3 is disposed inside the groove 2. The clamping mechanism 3 includes a motor 301, which is embedded in one side of the outer wall of the support platform 1. A worm gear 302 is fixedly installed at the power output end of the motor 301. A worm wheel 303 is rotatably connected to one end of the worm gear 302 that passes through the support platform 1. A bidirectional threaded rod 304 extends from the inside of the worm wheel 303. A slider 305 is slidably connected to the outer wall of one end of the bidirectional threaded rod 304 that passes through the groove 2. A connecting rod 306 is rotatably connected to the top of the slider 305. A clamping plate 307 is fixedly installed at the top of the connecting rod 306. A connecting ring 308 is rotatably connected to one side of the outer wall of the clamping plate 307. A bearing block 309 is rotatably connected to one axial end of the connecting ring 308. The bidirectional threaded rod 306... 4. The slider 305 is threadedly connected to the connecting rod 306, forming a rotating structure with the clamping plate 307. After the forging workpiece is placed on the bearing platform 1, the motor 301 drives the worm gear 302 and worm wheel 303 to drive the two bidirectional threaded rods 304 to drive the corresponding two sliders 305. The clamping plate 307 clamps the forging workpiece through the connecting rod 306. It should be noted that several clamping plates 307 are set and are rotatably connected to each other through the connecting ring 308 and the bearing block 309. When the connecting rod 306 and the slider 305 are rotatably connected, they can fit the irregular shape of the forging workpiece. After automatically adjusting the angle according to the forging workpiece, they can fully fit and limit the positioning and clamping effect, thus making it suitable for forging workpieces with irregular or non-standard shapes and improving the overall applicability and comprehensiveness of the clamping device. Example 2

[0024] In addition to all the technical features in Embodiment 1, this embodiment also includes: a fixing block 4 is fixedly installed on one side of the top slide groove 2 of the support platform 1; a limiting mechanism 5 is provided on one side of the fixing block 4; the limiting mechanism 5 includes a connecting rod 501, which is fixed to one side of the outer wall of the connecting rod 306; an insertion plate 502 is fixed to the end of the connecting rod 501 away from the connecting rod 306; a support shaft 503 is rotatably connected inside the insertion plate 502; a hydraulic rod 506 is embedded in the outer wall of the fixing block 4; an abutment plate 504 is fixedly installed at the power output end of the hydraulic rod 506; a slot 505 is provided on the outer wall of the abutment plate 504 corresponding to the position of the support shaft 503; a rotating structure is formed between the insertion plate 502 and the support shaft 503; and a rotating structure is formed between the support shaft 503 and the slot 505. The sliding structure features a connecting rod 501 that, driven by the slider 305 and connecting rod 306, slides and rotates with the slot 505 via the insertion plate 502 and support shaft 503. Simultaneously, the connecting rod 306 drives the connecting rod 501 to rotate and connect with the slider 305 and clamping plate 307, thus preventing any limiting. This allows the contact plate 504 to contact one side of the forging workpiece, providing initial limiting. Subsequently, the hydraulic rod 506 embedded in the fixing block 4 extends, pushing the contact plate 504 to further increase the contact force, preventing loosening. This provides limiting clamping on both sides where clamping plates 307 are not installed, improving the stability of forging workpiece positioning. It is also suitable for clamping and positioning irregularly shaped or irregularly shaped forging workpieces from both sides.

[0025] Working principle: When the forged workpiece is placed on the support platform 1, the motor 301 drives the worm gear 302, which in turn drives the worm wheel 303 to push the two bidirectional threaded rods 304 to push the corresponding two sliders 305 to slide relative to each other along the slide groove 2. This, in turn, causes the clamping plates 307 to clamp the forged workpiece via the connecting rod 306. Several clamping plates 307 are provided, and they are rotatably connected to each other via connecting rings 308 and support blocks 309. These clamping plates, in conjunction with the connecting rods 306 and sliders 305, allow the workpiece to be clamped according to its shape. The wall rotates and conforms to the contact plate for positioning. While the connecting rod 306 slides, it drives the connecting rod 501 to slide and engage with the slot 505 of the contact plate 504 via the insertion plate 502 and the support shaft 503, and rotates to connect via the support shaft 503. This automatically adjusts the angle and position. In conjunction with the hydraulic rod 506 embedded in the fixing block 4, the contact plate 504 is pushed, which can clamp and position the forging workpiece at a position where the clamping plate 307 is not set, further improving the stability of the forging workpiece limit clamping.
