The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.
[0036] like Figure 1 and Figure 2As shown, an embodiment of the present invention provides a workpiece casting waste removal device for cutting the sprue 10, sprue 11, and slag bag 12 on a workpiece 1. The workpiece casting waste removal device mainly includes a frame 100, a worktable 200, a first robotic arm, a shearing assembly 300, a punching assembly 400, and a second robotic arm. The frame 100 includes a first station, a second station, and a third station. The worktable 200 is provided with multiple clamping assemblies 210 for fixing the workpiece 1 located on the worktable 200. The first robotic arm corresponds to the first station and is used to place the workpiece 1 to be processed onto the worktable 200. The shearing assembly 300 corresponds to the second station and is used to cut the sprue 10 and sprue 11 on the workpiece 1. The punching assembly 400 corresponds to the third station and is used to remove the slag bag 12 from the workpiece 1. The second robotic arm is used to drive the worktable 200 to reciprocate between the first station, the second station, and the third station. During operation, the first robotic arm precisely places the workpiece 1 to be processed onto the worktable 200 at the first station. Multiple clamping components 210 on the worktable 200 then activate and fix the workpiece 1 to prevent displacement during subsequent processing. Next, the second robotic arm drives the worktable 200 to move to the second station. At this time, the shearing component 300 starts operating to cut and remove the material handle 10 and the sprue 11 on the workpiece 1. After the cutting is completed, the second robotic arm continues to move the worktable 200 to the third station. The punching component 400 then starts and removes the slag bag 12 on the workpiece 1 through the contour tooling 430. After all the waste removal processes are completed, the relevant components are reset, waiting for the processing of the next workpiece. This device integrates three workstations and corresponding functional components through a spatially staggered structural design. Combined with a robotic arm, it achieves automatic transfer and positioning of workpieces, eliminating the need for repeated handling and equipment switching. This significantly simplifies the waste removal process and improves processing efficiency. At the same time, the automated clamping, cutting, and punching operations not only ensure processing accuracy and prevent workpieces from becoming loose or damaged due to manual operation, but also reduce human intervention, lower labor costs, and meet the needs of automated production.
[0037] like Figure 3As shown, the clamping assembly 210 includes a fixed base 211, a linkage arm 212, a pressing block 213, and a pressing drive cylinder 214. One end of the linkage arm 212 is hinged to the fixed base 211 via a first rotating shaft 215, and the other end is hinged to the pressing block 213 via a second rotating shaft 216. The end of the pressing block 213 is hinged to the telescopic rod 2140 of the pressing drive cylinder 214 via a third rotating shaft 217. A pressing part 2130 for pressing the workpiece 1 is provided on the end of the pressing block 213 away from the third rotating shaft 217. During operation, the telescopic rod 2140 of the pressing drive cylinder 214 extends and retracts, causing the pressing block 213 to rotate around the third rotating shaft 217. Simultaneously, the linkage arm 212 rotates in cooperation with the first rotating shaft 215 and the second rotating shaft 216, causing the pressing part 2130 to move towards or away from the workpiece 1, thereby achieving the action of pressing or releasing the workpiece 1. Specifically, when the telescopic rod 2140 extends, the pressing part 2130 moves downward and presses the workpiece 1 tightly; when the piston rod retracts, the pressing part 2130 lifts upward, releasing the constraint on the workpiece 1. The clamping force of the pressing part 2130 can be precisely controlled by the air pressure of the pressing drive cylinder 214, which can prevent the workpiece 1 from loosening and shifting during cutting, and also prevent excessive pressure from causing deformation or surface damage to the workpiece 1. At the same time, the automated clamping action reduces manual operation steps and improves clamping efficiency.
[0038] like Figures 4-6 As shown, the shearing assembly 300 includes a hydraulic shear 310, which is mounted on the frame 100 along the Z-axis and can rotate around the Z-axis to cut the shank 10 and sprue 11 on the workpiece 1 at different positions. During operation, the second robotic arm first delivers the workpiece 1 to the second workstation, where the hydraulic shear 310 cuts the shank 10 and sprue 11. During this process, the hydraulic shear 310 can rotate around the Z-axis, coordinating with the second robotic arm to control the posture of the workpiece 1. The entire process requires no manual adjustment of the workpiece 1's posture, enabling automated continuous operation. This design significantly improves cutting efficiency, avoids errors and safety risks associated with manual operation, and provides stable hydraulic shear force suitable for different materials.
[0039] Specifically, the shearing assembly 300 also includes a support bearing 320, a mounting plate 330, and a rotary drive 340. The outer ring 321 of the support bearing 320 is fixed to the frame 100. The hydraulic shears 310 are fixed to the inner ring 322 of the support bearing 320 via the mounting plate 330. The rotary drive 340 is used to apply rotational force to the mounting plate 330 and / or the inner ring 322 of the support bearing 320, so as to drive the inner ring 322 of the support bearing 320 to rotate relative to the outer ring 321 of the support bearing 320, so that the hydraulic shears 310 rotates around the Z-axis. During operation, the rotary drive component 340 first receives an action command and applies a directional rotational force to the inner ring 322 of the mounting plate 330 or the support bearing 320. Since the outer ring 321 of the support bearing 320 is fixed on the frame 100, the inner ring 322 can rotate stably relative to the outer ring 321 under the action of the rotational force. At the same time, the rotating inner ring 322 drives the hydraulic shears 310 to rotate synchronously around the Z-axis through the mounting plate 330. When the hydraulic shears 310 rotates to the cutting position of the workpiece 1's shank 10 and sprue 11, the shear blades close to complete the cutting. Through the cooperation of the inner and outer rings of the support bearing 320, the frictional resistance of the hydraulic shears 310 during rotation is significantly reduced, reducing component wear and extending service life.
[0040] The rotary drive component 340 includes a mounting base 341, a rotating frame 342, and a rotary drive cylinder 343. The mounting base 341 is fixed on the frame 100. The rotating frame 342 is fixed on the mounting base 341 by a bearing 344 and can rotate around the Z-axis. The cylinder body 3430 of the rotary drive cylinder 343 passes through the rotating frame 342 and is fixedly connected to the rotating frame 342. The piston rod 3431 of the rotary drive cylinder 343 is rotatably connected to the mounting plate 330. During operation, the rotary drive cylinder 343 first receives an action signal, and its piston rod 3431 extends and retracts axially. This extension and retraction action generates a pushing and pulling force on the mounting plate 330. Since the rotating frame 342 is connected to the mounting base 341 fixed on the frame 100 via the bearing 344, and the cylinder body 3430 is fixed to the rotating frame 342, under the force of the piston rod 3431, the rotating frame 342 rotates around the Z-axis. This, in turn, drives the mounting plate 330 to rotate synchronously via the cylinder body 3430 and the piston rod 3431, ultimately achieving the rotation of the inner ring 322 of the support bearing 320 and the hydraulic shears 310 around the Z-axis. The mounting base 341 is fixed to the frame 100, and the support of the bearing 344 for the rotating frame 342 ensures the stability of the axis of the rotating frame 342 during rotation, avoiding drive errors caused by misalignment.
[0041] like Figure 5 As shown, a pair of mounting plates 330 are provided, and the pair of mounting plates 330 are symmetrically arranged on both sides of the hydraulic shear 310; further reference Figure 5In this embodiment, the mounting plate 330 has an L-shaped structure, and its horizontal edge 331 is fixedly connected to the inner ring 322 of the support bearing 320. The vertical edge 332 of the mounting plate 330 is fixedly connected to the hydraulic shears 310. A reinforcing rib 333 is fixedly connected between the horizontal edge 331 and the vertical edge 332 of the mounting plate 330, with the vertical edge 332 extending along the Z-axis. The reinforcing rib 333 between the horizontal edge 331 and the vertical edge 332 significantly enhances the structural strength of the mounting plate 330, resisting the reaction force generated by the hydraulic shears 310 during shearing, reducing the risk of deformation of the mounting plate 330, extending the service life of the component, and avoiding positioning errors of the hydraulic shears 310 caused by deformation of the mounting plate 330, further ensuring the stability of the cutting quality.
[0042] The hydraulic shears 310 pass through the inner ring 322 of the support bearing 320 in the Z-axis direction to avoid interference with the inner ring 322 during the shearing process. Specifically, the hydraulic shears 310 includes a hydraulic cylinder 311 and shears 312. The hydraulic cylinder 311 is located directly above the support bearing 320, and the blade of the shears 312 is located directly below the support bearing 320. It is worth noting that since the hydraulic shears 310 is a finished product, its specific structural details will not be described further.
[0043] like Figure 7 As shown, the punching assembly 400 includes a punching drive cylinder 410, a crossbeam 420, and multiple contouring fixtures 430. The punching drive cylinder 410 is fixed to the frame 100. The crossbeam 420 is fixedly connected to the drive rod 411 on the punching drive cylinder 410. The multiple contouring fixtures 430 are fixed to the crossbeam 420 for removing the slag bag 12 from the workpiece 1. During operation, the punching drive cylinder 410 first receives an action command, and its drive rod 411 extends and retracts in the vertical direction. Since the crossbeam 420 is fixedly connected to the drive rod 411, the extension and retraction of the drive rod will drive the crossbeam 420 to move up and down synchronously, thereby causing the multiple contouring fixtures 430 fixed on the crossbeam to move together with the crossbeam. After workpiece 1 is conveyed to the third station, the contouring fixture 430 moves downward with the crossbeam 420. Its contouring structure precisely fits the slag bale 12 of workpiece 1. Through the downward force transmitted by the punching drive cylinder 410, the slag bale 12 is quickly peeled off from workpiece 1. After punching, the punching drive cylinder 410 drives the drive rod 411 to reset, causing the crossbeam 420 and the contouring fixture 430 to return to their initial positions, awaiting the punching operation of the next workpiece. By integrating multiple contouring fixtures 430 on the crossbeam 420, multiple slag bales 12 of workpiece 1 can be punched simultaneously at one time. Compared with operating one fixture at a time, this greatly improves punching efficiency and reduces the processing cycle of the workpiece. Furthermore, synchronous punching has fewer positioning movements compared to operating one at a time, resulting in better accuracy.
[0044] To ensure the stability of the crossbeam 420 in the vertical direction, sliders 421 are fixed at both ends of the crossbeam 420, and slide rails 422 that are slidably connected to the sliders 421 are fixed on the frame 100. The cooperative design of the sliders 421 and slide rails 422 improves the guiding accuracy and running smoothness of the crossbeam 420 during its up-and-down movement, and avoids tilting or jamming of the crossbeam 420 due to vibration or uneven load.
[0045] In this embodiment, the punching assembly 400 further includes a clamping cylinder 440 and a clamping block 450 fixedly connected to the telescopic rod of the clamping cylinder 440. The clamping block 450 is used to apply a vertically downward pressing force to the workpiece 1 located at the third station. Before the punching assembly 400 performs the punching operation, the clamping cylinder 440 is activated first, and its telescopic rod extends downward, driving the clamping block 450 to press down synchronously until the clamping block 450 contacts and clamps the workpiece 1, ensuring that the workpiece 1 remains stable during the punching process and preventing punching deviations or equipment damage caused by workpiece displacement.
[0046] The workpiece casting waste removal device also includes a positioning table 500, which is located at the third station and directly below the clamping cylinder 440, and is used to support the workpiece 1 located at the third station. The positioning table 500 is used to support the bottom of the workpiece 1 during the punching process, and works in conjunction with the clamping cylinder 440 to stably clamp the workpiece 1 during the punching process, preventing displacement or deformation due to uneven force.
[0047] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
