Description

Technical Field

[0001] This utility model belongs to the technical field of grinding devices, and in particular relates to a grinding device for metal castings with multi-angle adjustment. Background Technology

[0002] Metal castings are shaped metal objects obtained by pouring molten metal into a mold cavity and allowing it to cool and solidify. After casting, metal castings require grinding and polishing. Grinding equipment is the core equipment in post-casting processing, used to remove burrs, flash, gate residue, and for surface polishing. Due to the complex surface protrusions and depressions of metal castings, existing grinding equipment struggles to grind castings at different angles. Furthermore, it is difficult to grind the clamping areas of the casting during a single grinding process, often requiring secondary loading and unloading, which affects processing efficiency and quality.

An adjusting block is threadedly connected to the outer surface of the adjusting threaded rod, and a rotating frame is rotatably connected to the right end of the adjusting block. A telescopic rod is fixedly connected to the right end of the rotating frame, and a linkage arm is fixedly connected to the other end of the telescopic rod. The inner surface of the linkage arm is rotatably connected to the inner surface of the slide, and a third motor is fixedly connected to the inner surface of the linkage arm. A grinding head is fixedly connected to the output end of the third motor.

[0006] As a preferred embodiment of the above technical solution, the clamping assembly includes a side frame fixedly connected to the upper right side of the worktable, a top frame slidably connected to the left end of the side frame, turntables rotatably connected to the inner surfaces of both the worktable and the top frame, lateral guide rods fixedly connected to the side of each turntable away from the other turntable, a shaped frame slidably connected to the outer surface of the lateral guide rod and the inner surface of the turntable, a clamp fixedly connected to the outer surface of the shaped frame, and the outer surface of the clamp slidably connected to the outer surface of the turntable.

[0007] As a preferred embodiment of the above technical solution, a shock absorber is fixedly connected between the opposing surfaces of the adjacent irregular-shaped frames, and a fourth motor is fixedly connected to the end of each turntable away from the other turntable. A clamping threaded rod is fixedly connected to the output end of the fourth motor, and the outer surface of the clamping threaded rod is threadedly connected to the inner surface of the right irregular-shaped frame.

[0008] As a preferred embodiment of the above technical solution, each turntable has a bevel gear ring fixedly connected to its end away from the other turntable.

[0013] Example 1 This utility model provides a multi-angle adjustable metal casting grinding device, such as... Figures 1 to 7As shown, the system includes a worktable 1 and an adjustment assembly 5. The adjustment assembly 5 includes an arc-shaped frame 501 fixedly connected to the output end of a second electric push rod 4. A semi-circular external gear ring 502 is fixedly connected to the upper end of the arc-shaped frame 501. A slide 503 is slidably connected to the inner arc surface of the arc-shaped frame 501. A first motor 504 is fixedly connected to the upper end of the slide 503. A gear 505 is fixedly connected to the output end of the first motor 504.

A first electric push rod 2 is fixedly connected to the upper left side of the worktable 1. The output end of the first electric push rod 2 is fixedly connected to... An L-shaped intermediate frame 3 is provided, with a second electric push rod 4 fixedly connected to the upper right end of the L-shaped intermediate frame 3. The output end of the second electric push rod 4 is fixedly connected to the left end of the adjustment component 5. A clamping component 6 is provided on the right side of the worktable 1. Through the action of the first electric push rod 2 and the second electric push rod 4, the adjustment component 5 can be driven to adjust its position, thereby ensuring the overall flexibility and practicality. When the first motor 504 is started, the slide 503 can be driven to move in an arc through the meshing transmission of the gear 505 and the semi-circular external gear ring 502 and the limiting of the slide 503 by the arc frame 501, which facilitates the movement of the slide 503 in an arc, making it easier to handle irregular protrusions and depressions on the metal casting. To adjust the horizontal grinding angle, the second motor 506 is started. By adjusting the threaded connection between the threaded rod 507 and the adjusting block 508, and the linkage action of the adjusting block 508, the rotating frame 509, the telescopic rod 510, and the linkage arm 511, the vertical grinding angle of irregular protrusions and depressions on the metal casting can be easily adjusted. Through the cooperation of the first motor 504 and the second motor 506, the metal casting can be ground at various lateral angles, improving the overall practicality and reliability. In conjunction with the first electric push rod 2 and the second electric push rod 4, the grinding head 513 is driven to process different positions of the metal casting at different angles.

[0014] like Figures 1 to 7As shown, the clamping assembly 6 includes a side frame 601 fixedly connected to the upper right side of the worktable 1. A top frame 602 is slidably connected to the left end of the side frame 601. Turntables 603 are rotatably connected to the inner surfaces of both the worktable 1 and the top frame 602. Lateral guide rods 604 are fixedly connected to the side of each turntable 603 away from the other turntable 603. A shaped frame 605 is slidably connected to the outer surface of the lateral guide rod 604 and the inner surface of the turntable 603.

A shock absorber 607 is fixedly connected between the opposing surfaces of adjacent shaped frames 605. A fourth motor 608 is fixedly connected to the end of each turntable 603 away from the other turntable 603. The output end of the 8 is fixedly connected to a clamping threaded rod 609. The outer surface of the clamping threaded rod 609 is threadedly connected to the inner surface of the right-side irregular frame 605. A bevel gear ring 610 is fixedly connected to the end of each turntable 603 away from the other turntable 603. A lateral bevel gear 611 is rotatably connected to the inner surface of the worktable 1 and the inner surface of the top frame 602. The outer surface of the lateral bevel gear 611 meshes with the outer surface of the bevel gear ring 610. A fifth motor 612 is fixedly connected to the upper end of the side frame 601. A cross-shaped rod 613 is fixedly connected to the output end of the fifth motor 612. The other end of the cross-shaped rod 613 is rotatably connected to the inner surface of the worktable 1. The outer surface of the cross-shaped rod 613 is slidably connected to the inner surface of the lateral bevel gear 611. Through the cross-shaped structure design of the cross-shaped rod 613, the lateral bevel gear 611 can be slidably connected. While achieving vertical sliding limit, it drives synchronous rotation to ensure overall stability. A sixth motor 614 is fixedly connected to the upper end of the side frame 601. An adjusting threaded rod 615 is fixedly connected to the output end of the sixth motor 614. The outer surface of the adjusting threaded rod 615 is threadedly connected to the inner surface of the top frame 602. A guide column 616 is fixedly connected between the side frame 601 and the worktable 1. When the sixth motor 614 is started, the top frame 602 can be driven to move up and down through the threaded transmission between the adjusting threaded rod 615 and the upper top frame 602. This allows the height of the clamped metal casting to be adjusted through the upper clamp 606, facilitating the adjustment component 5 for metal castings of different lengths. After grinding, the outer surface of the guide column 616 is slidably connected to the inner surface of the top frame 602. Through the threaded transmission between the clamping threaded rod 609 and the irregular frame 605, and the guiding action of the lateral guide rod 604, the clamping threaded rod 609 can rotate, driving the clamp 606 to move inward. Through the linkage action of the irregular frame 605 and the shock absorber 607, the various irregular frames 605 can be driven to move synchronously, thereby ensuring that the various clamps 606 move synchronously to clamp the metal casting. At the same time, the shock absorber 607 cancels out the vibration generated during clamping and processing, improving the overall stability and service life. The upper and lower clamps 606 are evenly distributed circumferentially when viewed from above.This system ensures that metal castings can be clamped at different positions during a single machining operation, avoiding the need for secondary loading and unloading at the clamping points and improving overall practicality and functionality. The fifth motor 612, through the meshing transmission of the bevel gear ring 610 and the lateral bevel gear 611, drives the upper and lower clamps 301 to rotate synchronously, ensuring the relative position stability of the upper and lower clamps 606. Simultaneously, in conjunction with the adjusting component 5, it allows for machining of metal castings at more complex angles and curves, further enhancing overall functionality and practicality.

[0015] Working Principle: The metal casting is placed in the middle of the lower clamp 606. The fourth motor 608 is started, driving the clamp 606 to hold the metal casting. Through the threaded transmission between the clamping threaded rod 609 and the irregular frame 605, and the guiding action of the lateral guide rod 604, the clamp 606 moves inward as the clamping threaded rod 609 rotates. Through the linkage between the irregular frame 605 and the shock absorber 607, each irregular frame 605 moves synchronously, ensuring that all clamps 606 move synchronously to hold the metal casting. Simultaneously, the shock absorber 607 cancels out vibrations generated during clamping and processing, improving overall stability and ease of use. With a long service life, the upper and lower clamps 606 are evenly spaced circumferentially when viewed from above, ensuring that the metal casting can be clamped at different positions during a single machining operation. This avoids the need for secondary loading and unloading at the clamping points, improving overall practicality and functionality. Activating the first electric push rod 2 and the second electric push rod 4 adjusts the machining position of the adjusting component 5, activating the first motor 504. Through the meshing transmission of the gear 505 and the semi-circular external gear ring 502, and the limiting effect of the arc-shaped frame 501 on the slide 503, the slide 503 can be driven to move in an arc, facilitating the adjustment of the lateral grinding angle for irregular protrusions and depressions on the metal casting. Activating the first electric push rod 2... The second electric motor 506, through the threaded connection of the adjusting threaded rod 507 and the adjusting block 508, and the linkage action of the adjusting block 508, the rotating frame 509, the telescopic rod 510, and the linkage arm 511, facilitates the vertical grinding angle adjustment of irregular protrusions and depressions on the metal casting. Through the cooperation of the first electric motor 504 and the second electric motor 506, various lateral angle grinding of the metal casting can be performed, improving overall practicality and reliability. Starting the fifth electric motor 612, through the meshing transmission of the bevel ring 610 and the lateral bevel gear 611, drives the upper and lower turntables 603 to rotate synchronously, thereby ensuring the relative position stability of the upper and lower clamps 606. Simultaneously, it works in conjunction with the first electric push... Rod 2, second electric push rod 4, first motor 504, second motor 506 and grinding head 513 work together to process the metal casting with more complex angles and curves, improving the overall functionality and practicality. The sixth motor 614 is started, which drives the top frame 602 to move down and starts the upper fourth motor 608 to clamp the metal casting. Then the lower fourth motor 608 is started to release the lower clamp 606 from the metal casting. Simultaneously, the first electric push rod 2, second electric push rod 4, first motor 504, second motor 506, grinding head 513, fifth motor 612 and sixth motor 614 are started to grind the unprocessed parts on the metal casting.
