Description

Technical Field

[0001] This utility model relates to the technical field of metal casting processing equipment, and in particular to a tooling for processing burrs and flash on metal castings. Background Technology

[0002] After metal castings have cooled and solidified, excess metal flash and burrs often remain on their surfaces, parting surfaces, or edges. To ensure the dimensional accuracy, appearance quality, and safety of subsequent assembly, these flashes and burrs must be removed. In existing machining processes, specialized deburring fixtures are typically used to hold the casting in place and perform grinding.

[0003] However, existing tooling for burr and flash removal on metal castings has some significant shortcomings in practical use. Traditional tooling often uses manual bolt clamps or simple mechanical vises for fixing. In mass production, this method makes workpiece clamping and unclamping cumbersome and time-consuming, severely impacting processing efficiency. More importantly, for castings with complex shapes or those that vibrate significantly during processing, existing simple clamping mechanisms often fail to provide a constant and sufficient clamping force, easily causing the casting to loosen or shift during high-speed brushing. This not only reduces processing accuracy but may even lead to flying castings and injuries. Furthermore, existing tooling typically lacks effective protective measures, allowing metal shavings generated during processing to scatter easily, worsening the working environment.

[0004] Therefore, this utility model proposes a tooling for processing burrs and flash on metal castings to overcome the shortcomings of the prior art. Utility Model Content

[0005] In view of the problems of cumbersome workpiece clamping operation, poor clamping stability leading to low processing accuracy, and lack of effective safety protection in the existing metal casting flash and burr processing fixtures, this utility model aims to provide a metal casting flash and burr processing fixture with an improved structure that can effectively solve the above problems.

[0006] This utility model provides a tooling for processing burrs and flash on metal castings, comprising: a housing, and a support frame fixedly connected inside the housing, an electric lifting rod fixedly connected to the bottom of the support frame, a first motor fixedly connected to the output end of the electric lifting rod, and a universal roller brush fixedly connected to the output end of the first motor; a support column fixedly connected to the bottom of the housing, and a worktable fixedly connected to the top of the support column; a fixed platform fixedly connected inside the housing; and a clamping mechanism provided on the top of the fixed platform.

[0007] The core innovative component of the clamping mechanism has the following structure: a support block is fixedly connected to the top of the fixed platform, and a hydraulic rod is fixedly connected to the outside of the support block; a fixed block is fixedly connected to the top of the fixed platform, and a connecting block is fixedly connected to the top of the fixed block; a transmission block is connected to the output end of the hydraulic rod; two grippers are rotatably connected inside the connecting block; and two transmission rods are rotatably connected inside the transmission block.

[0008] Furthermore, the output end of the hydraulic rod is fixedly connected to the transmission block, and the end of the transmission rod away from the transmission block is rotatably connected to the two grippers respectively. The grippers are rotatably connected inside the connecting block. The hydraulic rod, transmission block, transmission rod and grippers are combined in a linkage manner. When the hydraulic rod moves, it drives the transmission block and transmission rod to move, thereby driving the two grippers to rotate around the connecting block, thereby realizing the stable clamping of the casting on the worktable.

[0009] Preferably, two motor protective shells are fixedly connected to the bottom of the outer shell, a second motor is installed inside the motor protective shell, a threaded rod is fixedly connected to the output end of the second motor, and a protective plate is threaded between the two threaded rods to protect and limit the worktable and the components below.

[0010] Preferably, the protective plate is slidably connected to the outside of the support column through the middle, and the protective plate moves up and down along the length of the support column to ensure the stability of the lifting process.

[0011] Preferably, the fixed platform has a slot inside, which serves as a basic carrier for supporting components such as the worktable and hydraulic rod.

[0012] Preferably, the transmission block is fixedly connected to the output end of the hydraulic rod through the connecting block to achieve effective power transmission and save space.

[0013] Preferably, one end of each of the two grippers in the same direction is rotatably connected inside the connecting block to form a lever-type opening and closing structure.

[0014] Preferably, the support frame provides mounting support for the electric lifting rod and the first motor, ensuring the structural stability of the processing components.

[0015] Preferably, the hydraulic rod, transmission block, transmission rod, and gripper constitute a clamping mechanism for clamping the casting on the worktable, and automatic clamping is achieved through hydraulic drive.

[0016] This utility model has the following beneficial effects: 1. This utility model, by setting up a linkage clamping mechanism that coordinates a hydraulic rod, a transmission block, a transmission rod and a gripper, can drive the transmission block and the transmission rod when the hydraulic rod is working, thereby driving the gripper to open and close synchronously. This solves the problems of low clamping and fixing efficiency, unstable structure or insufficient clamping force in the prior art for clamping and fixing castings, and achieves the technical effect of automated clamping, reliable clamping and stable structure.

[0017] 2. This utility model solves the problem in the prior art that the deburring device has a fixed height and is difficult to adapt to the processing needs of castings of different thicknesses or shapes by setting an electric lifting rod and using the output end of the electric lifting rod to drive the first motor and the universal roller brush to perform overall vertical lifting on the support frame. It achieves the technical effect of flexibly adjusting the processing position and improving the equipment's versatility and applicability. Attached Figure Description

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0021] Example: Please refer to Figures 1 to 3 This utility model provides a tooling for processing burrs and flash on metal castings, which aims to solve the structural defects in the prior art of low workpiece clamping and fixing efficiency, instability, and inability to flexibly adapt to the processing of castings of different heights during metal casting processing.

[0022] like Figure 1 and Figure 2 As shown, the metal casting burr processing fixture includes a housing 1 as an overall external protection and support frame, and a support frame 2 fixedly connected inside the housing 1. A fixed platform 11 is also fixedly connected inside the housing 1. A support column 13 is fixedly connected to the bottom of the housing 1, and a worktable 8 is fixedly connected to the top of the support column 13. The worktable 8 is used to place the metal casting to be processed. The fixed platform 11 is located below or to the side of the worktable 8 and serves as a bearing platform for the core clamping drive mechanism. The fixed platform 11 has a slot structure inside to reduce weight and facilitate installation and debugging.

[0023] Regarding the core workpiece fixing function of this embodiment, a support block 3 is fixedly connected to the top of the fixing platform 11. A hydraulic rod 5 is fixedly connected to the outside of the support block 3. The support block 3 serves to position and provide reaction force support to ensure the positional accuracy of the hydraulic rod 5 during operation. A fixing block 7 is also fixedly connected to the top of the fixing platform 11. A connecting block 16 is fixedly connected to the top of the fixing block 7. The connecting block 16 serves as the mounting base for the linkage mechanism. The output end of the hydraulic rod 5 extends horizontally and passes through the connecting block 16 before being fixedly connected to the transmission block 17. The transmission block 17 serves as the power transmission... The central hub has two rotatably connected transmission rods 18. The ends of these two transmission rods 18 away from the transmission block 17 are respectively rotatably connected to two grippers 19. The ends of these two grippers 19 in the same direction are rotatably connected to the pin positions inside the connecting block 16. This constitutes a linkage clamping mechanism in which the hydraulic rod 5 drives the transmission block 17, the transmission block 17 drives the transmission rods 18, and the transmission rods 18 push the grippers 19 to rotate around the connecting block 16. The opening and closing of the grippers 19 are controlled by the extension and retraction of the hydraulic rod 5 to achieve strong clamping of the castings on the worktable 8.

[0024] To facilitate the machining of castings, the metal casting burr and flash machining fixture in this embodiment further includes a machining execution mechanism, which is mounted on the support frame 2. Please refer to the following for details. Figure 1 and Figure 2The following is a detailed description of the processing mechanism: The support frame 2 is fixedly connected to the upper part of the interior of the outer shell 1. An electric lifting rod 4 is fixedly connected to the bottom of the support frame 2. A first motor 6 is fixedly connected to the output end of the electric lifting rod 4. A universal roller brush 14 is fixedly connected to the output end of the first motor 6. The support frame 2 provides stable mounting support for the electric lifting rod 4 and the first motor 6. In the assembled state, the electric lifting rod 4, the first motor 6, and the universal roller brush 14 together constitute a processing unit that can move vertically as a whole. The extension and retraction of the electric lifting rod 4 drives the first motor 6 and the universal roller brush 14 to move vertically, adjusting the relative height of the universal roller brush 14 and the metal casting on the worktable 8. This structure ensures that the universal roller brush 14 can flexibly adapt to the processing position of castings of different sizes, while the first motor 6 provides high-speed rotational power to the universal roller brush 14 to remove burrs and flash.

[0025] As a preferred embodiment, to prevent the splashing of slag generated during the machining of metal castings from causing injury to workers, and to prevent the castings or slag from shifting during machining, please refer to... Figure 1 The bottom of the outer casing 1 is fixedly connected to two motor protective shells 15. These two motor protective shells 15 are symmetrically distributed. A second motor 12 is installed inside each of them. The output end of the second motor 12 is vertically upward and fixedly connected to a threaded rod 10. A protective plate 9 is threadedly connected between the two threaded rods 10. The protective plate 9 spans between the two threaded rods 10.

[0026] As a further preferred embodiment, in order to ensure the guiding accuracy and stability of the protective plate 9 during the lifting process, the protective plate 9 has a through hole in the middle. The through hole passes through and is slidably connected to the outside of the support column 13. The support column 13 here has the dual functions of supporting the workbench 8 and sliding guide rail of the protective plate 9. When the second motor 12 drives the threaded rod 10 to rotate, the threaded transmission action converts the rotational motion into linear motion, driving the protective plate 9 to move up and down smoothly along the length direction of the support column 13, thereby flexibly adjusting the protective height according to processing requirements.

[0027] As another preferred embodiment, in order to optimize the structural layout of the equipment and reduce its weight, and to facilitate the subsequent positioning and installation of each component, the fixed platform 11 is provided with a slot. This slot structure serves as the basic feature of the fixed platform 11 for supporting components such as the workbench 8 and the hydraulic rod 5, and can effectively improve the overall structural compactness after the components are assembled.

[0028] Working principle: When deburring a metal casting is required, the casting is first placed on the worktable 8. Then, the hydraulic rod 5 is activated. The output end of the hydraulic rod 5 pushes the transmission block 17 that passes through the connecting block 16. The transmission block 17 drives two grippers 19 through two rotatably connected transmission rods 18. The ends of the two grippers 19 in the same direction are rotatably connected inside the connecting block 16. Under the push of the transmission rods 18, the grippers 19 rotate and close around the connection point of the connecting block 16, thereby firmly clamping the casting on the worktable 8. The clamping mechanism has a stable structure and a large clamping force. When the hydraulic rod 5 moves in the opposite direction, it drives the grippers 19 to open.

[0029] After clamping is completed, the electric lifting rod 4 is started. The electric lifting rod 4 is the driving component of the processing execution mechanism set on the support frame 2. It drives the first motor 6 and the universal roller brush 14, which are fixedly connected to the output end, to move up and down as a whole, and adjusts the relative height between the universal roller brush 14 and the part of the casting to be processed, so as to adapt to the processing requirements of different castings.

[0030] At the same time, the second motor 12, which is set inside the motor protective housing 15, is started. The second motor 12 drives the threaded rod 10, which is fixedly connected to its output end, to rotate. The threaded rod 10 drives the protective plate 9, which is threadedly connected to it, to rise through the threaded transmission. The protective plate 9 passes through the middle and is slidably connected to the outside of the support column 13, so that its lifting process remains stable. The raised protective plate 9 is used to block the debris that splashes during processing and ensures operational safety.

[0031] After the protective plate 9 is raised into position, the first motor 6 is started. The first motor 6 drives the universal roller brush 14, which is fixedly connected to its output end, to rotate at high speed. The high-speed rotating universal roller brush 14 grinds and removes the burrs on the casting. After processing, the electric lifting rod 4 drives the universal roller brush 14 to rise. The second motor 12 reverses to lower the protective plate 9. The hydraulic rod 5 moves in the opposite direction to release the gripper 19, so that the processed casting can be removed. The entire fixture solves the problems of unstable clamping and poor adaptability in the prior art through the coordinated action of the clamping mechanism, lifting mechanism and protective mechanism.

[0032] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
