[0025] 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.

[0026] Please see Figure 1-8 This utility model provides a technical solution: a cutting device for machining the inclined surface of castings, including an operating table 1. A support leg 2 is fixedly installed at the bottom of the operating table 1 to support the operating table 1 and raise the operating table 1 a certain height off the ground, which facilitates the operation and maintenance of the equipment and enhances the overall stability of the equipment, preventing it from tipping over due to vibration during processing. A clamping assembly 3 is provided on the top of the operating table 1, and a machining assembly 4 is provided on the top of the operating table 1 to the right of the clamping assembly 3. A protective mechanism 5 is provided on the top of the operating table 1, located outside the machining assembly 4 and extending to the bottom of the operating table 1.

[0027] The clamping assembly 3 includes a frame 31. The frame 31 is fixedly installed on the top left side of the operating table 1. An electric push rod 32 is fixedly installed on the inner top wall of the frame 31. An installation plate 33 that is slidably connected to the inner wall of the frame 31 is fixedly installed at the output end of the electric push rod 32. A movable clamping block 34 is fixedly installed at the bottom of the installation plate 33. A fixed clamping block 35 that is fixedly connected to the inner wall of the frame 31 is fixedly installed on the top of the operating table 1, providing a fixed support point for the casting. Together with the movable clamping block 34, the casting is stably clamped to ensure machining accuracy.

[0028] When the casting needs to be processed, the casting is placed between the fixed clamping block 35 and the movable clamping block 34 on the operating table. The electric push rod 32 is activated. The output end of the electric push rod 32 pushes the mounting plate 33 to slide downward on the inner wall of the frame 31. The mounting plate 33 drives the movable clamping block 34 to move downward, thereby cooperating with the fixed clamping block 35 to clamp and fix the casting, providing stable positioning for subsequent processing operations.

[0029] The processing component 4 includes a housing 401. The housing 401, located on the right side of the frame 31, is fixedly mounted on the top of the operating table 1. A servo motor 402 is fixedly mounted on the rear inner wall of the housing 401. A threaded rod 403, rotatably connected to the front inner wall of the housing 401, is fixedly mounted on the output shaft of the servo motor 402. A threaded block 404 is threadedly connected to the outer side of the threaded rod 403. A limit block 405 is fixedly mounted on the bottom of the threaded block 404. A limit frame 406 is fixedly mounted on the inner bottom wall of the housing 401. The limit block 405 extends to the inner side of the limit frame 406 and is slidably connected to it. A connecting block 407, extending to the top of the housing 401, is fixedly mounted on the top of the connecting block 407. An outer box 408 is fixedly mounted on the right side of the inner wall of the outer box 408. Two support rails 4 are fixedly mounted on the right side of the inner wall of the outer box 408. 09. A slide block 410 is slidably installed between the left sides of the two support rails 409. A frame 411 is fixedly installed on the left side of the slide block 410. An electric telescopic rod 412 is fixedly installed on the inner top wall of the outer box 408. The output end of the electric telescopic rod 412 is fixedly connected to the top of the frame 411. A servo motor 413 is fixedly installed on the right side of the inner wall of the frame 411. A half gear 414 is fixedly installed at the output shaft of the servo motor 413. A rotating shaft 415 is fixedly installed on the inner top wall of the frame 411. A swing plate 416 is rotatably connected to the outside of the rotating shaft 415. A driven gear 417 that meshes with the left side of the half gear 414 is fixedly installed on the right side of the swing plate 416. A machining head 418 is fixedly installed at the bottom of the swing plate 416. Different types of machining heads, such as milling cutters or grinding wheels, can be replaced according to different machining requirements.

[0030] The servo motor 402 is started, and its output shaft drives the threaded rod 403 to rotate on the front side of the inner wall of the housing 401. Since the threaded block 404 is threadedly connected to the threaded rod 403, and the limiting block 405 at the bottom of the threaded block 404 slides within the limiting frame 406, the rotational freedom of the threaded block 404 is restricted, allowing it to only move in a horizontal straight line along the threaded rod 403. The threaded block 404, through the connecting block 407, drives the outer housing 408 to move horizontally, thereby adjusting the horizontal position of the processing head 418. The electric telescopic rod 412 is then started, and its output end drives... The frame 411 slides on the support rail 409 via the slide block 410, enabling the machining head 418 to move vertically to meet the machining requirements at different heights. The servo motor 413 is started, and the output shaft of the servo motor 413 drives the half gear 414 to rotate. The half gear 414 meshes with the driven gear 417, causing the swing plate 416 to swing back and forth around the rotating shaft 415. The machining head 418 at the bottom of the swing plate 416 swings accordingly, realizing the cutting machining of the inclined surface of the casting. By controlling the rotation direction and speed of the servo motor 413, the swing angle and frequency of the machining head 418 can be adjusted to adapt to different machining requirements.

[0031] The inner top wall of the box 401 has a slotted hole that matches the movement trajectory of the connecting block 407. The inside of the threaded block 404 has a threaded hole that matches the threaded rod 403. The left side of the inner wall of the outer box 408 is open. The left side of the inner wall of the frame 411 is also open.

[0032] The protective mechanism 5 includes an arc-shaped fixing plate 501. An arc-shaped fixing plate 501 located outside the housing 401 is fixedly installed on the top of the operating table 1. Two mounting holes 502 are opened inside the operating table 1. A support rod 503 is rotatably connected between the front and rear sides of the inner wall of the mounting holes 502. A rotating block 504 extending to the outside of the mounting holes 502 is fixedly installed on the outer side of the support rod 503. A rectangular plate 505 is fixedly installed on the top of the rotating block 504. An arc-shaped plate 506 is fixedly installed between the tops of the two rectangular plates 505. A shielding canopy 507 is movably installed between the arc-shaped plate 506 and the arc-shaped fixing plate 501. The shielding canopy 507 unfolds or retracts under the action of the arc-shaped plate 506 and the arc-shaped fixing plate 501, effectively blocking debris generated during processing, protecting the operator's safety, and providing support. A gear 508 extending to the outside of the mounting hole 502 is fixedly installed on the outer side of the rod 503. A rectangular frame 509 is fixedly installed on the bottom of the operating table 1. A strip plate 510 extending to the front two sides of the rectangular frame 509 is slidably installed on the inner bottom wall of the rectangular frame 509. A support block 511 slidably connected to the inner top wall of the rectangular frame 509 is fixedly installed on the top and bottom of the strip plate 510. A toothed plate 512 is fixedly installed at both the front and rear ends of the strip plate 510. The two toothed plates 512 mesh with the bottom of the two gears 508 respectively. A hydraulic cylinder 513 is fixedly installed on the left side of the inner wall of the rectangular frame 509. The output end of the hydraulic cylinder 513 is fixedly connected to the left side of the strip plate 510. The hydraulic cylinder 513 drives the strip plate to move linearly through telescopic movement, providing power for the movement of the strip plate 510, thereby controlling the opening and closing of the canopy 507.

[0033] The inner walls of the rectangular frame 509 are open on both the front and back sides, and the canopy 507 is made of soft material.

[0034] When using the equipment, place it on a stable work surface, ensuring the support legs 2 firmly support the operating table 1. Check that all components are securely connected, and that electrical components such as the electric push rod 32, servo motor 402, electric telescopic rod 412, servo motor 413, and hydraulic cylinder 513 are properly powered and free from damage or malfunction. Prepare a suitable machining head 418 according to the size and shape of the casting to be processed, and install it at the bottom of the swing plate 416. Place the casting to be processed between the fixed clamping block 35 and the movable clamping block 34 on the operating table 1, ensuring the casting is placed stably and in the correct position. Start the machine. The electric push rod 32 moves the movable clamping block 34 downwards to clamp and fix the casting. Observe whether the casting is firmly clamped. If necessary, the stroke of the electric push rod 32 can be adjusted appropriately. Start the servo motor 402. By controlling the forward and reverse rotation and rotation time of the servo motor 402, the thread rod 403 drives the thread block 404 to move horizontally. Then, the horizontal position of the machining head is adjusted through the connecting block 407 and the outer box 408, so that the machining head is aligned with the inclined surface to be machined on the casting. Start the electric telescopic rod 412. According to the height of the casting and the processing requirements, adjust the vertical position of the frame 411 and the machining head 418. Positioning ensures that the machining head 418 accurately contacts the machining area of ​​the casting. The hydraulic cylinder 513 is activated, causing its output end to push the strip 510 to move. Through the meshing transmission of the toothed plate 512 and gear 508, the arc-shaped plate 506 rotates upward, unfolding the shield 507 to form a protective barrier and prevent debris from splashing during machining. The servo motor 413 is activated, causing the half gear 414 to drive the driven gear 417 and the swing plate 416 to swing. The machining head 418 then performs cutting machining on the inclined surface of the casting. During machining, the servo motor 418 can be adjusted in a timely manner according to the machining effect and requirements. The rotation speed and direction of component 3, as well as the position parameters of electric push rod 32, servo motor 402, and electric telescopic rod 412, are adjusted to obtain ideal processing quality. After processing, the servo motor 413 is turned off first to stop the swing of the processing head 418. Then, the electric telescopic rod 412, servo motor 402, and electric push rod 32 are turned off in sequence to restore the processing component 4 and clamping component 3 to their initial positions. The hydraulic cylinder 513 is then started in reverse to retract the shield 507, the protective device 5 is released, and the processed casting is removed from the clamping component 3. The debris and debris on the operating table are cleaned to keep the equipment and work area clean.

[0035] Turn off the power to the equipment and perform routine maintenance, such as cleaning the equipment surface, checking the connections of electrical components, and lubricating moving parts, to ensure the normal operation of the equipment and extend its service life.

[0036] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0037] In summary, this cutting equipment for machining inclined surfaces of castings, by incorporating a protective mechanism 5, activates a hydraulic cylinder 513 when protection is required. The output end of the hydraulic cylinder 513 pushes the strip 510 to slide within the rectangular frame 509. The strip 510 drives the support block 511 to slide against the top wall within the rectangular frame 209. Simultaneously, the toothed plates 512 at both ends of the strip 510 mesh with the gear 508, causing the gear 508 to rotate. The gear 508 then drives the support rod 503 to rotate within the mounting hole 502. The support rod 503, through a rotating block 504, drives the rectangular plate 505 to rotate. The rectangular plate 505 drives the arc plate 506 to rotate upwards, and the shield 507 between the arc plate 506 and the arc fixed plate 501 is unfolded to form a protective barrier, preventing the debris generated during processing from splashing into the surrounding environment and protecting the safety of the operators. When protection is not required, the hydraulic cylinder 513 is activated in reverse to make the arc plate 506 rotate downwards and the shield 507 is retracted, thus achieving the purpose of having a spark protection structure. This solves the problem that the lack of a spark protection structure causes sparks to be discharged and splashed, posing a safety hazard and affecting the use of the cutting equipment.
