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.

[0017] Example 1:

[0018] This utility model provides a grinding mechanism for processing forklift parts, including a frame 1, a worktable 2 fixedly mounted on the frame 1, a protective shell 3 fixedly mounted on the worktable 2, a gantry frame 4 and a Y-axis moving mechanism 5 fixedly mounted on the worktable 2, an X-axis moving mechanism 6 fixedly mounted on the gantry frame 4, a Z-axis moving mechanism 7 fixedly connected to the X-axis moving mechanism 6, a grinding mechanism 8 fixedly connected to the Z-axis moving mechanism 7, and a rotary clamping mechanism 9 fixedly connected to the Y-axis moving mechanism 5. The grinding mechanism 8 includes a rotary adjusting cylinder 10, an assembly frame 11, and a grinding machine 12. The rotary adjusting cylinder 10 is fixedly connected to the assembly frame 11, and the grinding machine 12 is fixedly mounted on the assembly frame 11. A chip blowing nozzle 13 is fixedly mounted on the assembly frame 11 next to the grinding machine 12. The rotary clamping mechanism 9 includes a rotary motor 14 and a clamping head 15, with the rotary motor 14 driving and connecting the clamping head 15. A rubber pad 16 is fixedly mounted on the clamping head 15.

[0019] Through the above technical solution, the workbench 2 of this utility model is fixedly installed with a gantry frame 4 and a Y-axis moving mechanism 5. The Y-axis moving mechanism 5 is fixedly connected to a rotating clamping mechanism 9. The gantry frame 4 is fixedly installed with an X-axis moving mechanism 6. The X-axis moving mechanism 6 is fixedly connected to a Z-axis moving mechanism 7. The Z-axis moving mechanism 7 is fixedly connected to a grinding mechanism 8. The flexibility of the grinding mechanism 8 is improved through the three-axis movement, reducing manual intervention in the grinding process and improving processing efficiency.

[0020] Example 2:

[0021] In this embodiment, the frame 1 serves as the supporting foundation for the entire device, with a worktable 2 fixedly mounted on its upper part. The surface of the worktable 2 is provided with a protective shell 3 to protect against flying debris generated during processing. A gantry frame 4 and a Y-axis moving mechanism 5 are also installed on the worktable 2, forming a stable processing space.

[0022] The gantry frame 4 is rigidly mounted above the worktable 2, and an X-axis moving mechanism 6 is fixedly installed on its crossbeam. This X-axis moving mechanism 6 uses a linear guide rail and a servo motor for drive, enabling precise positioning and movement along the length of the worktable 2. A Z-axis moving mechanism 7 is fixedly connected to the slider of the X-axis moving mechanism 6, and this Z-axis moving mechanism 7 uses a cylinder to achieve lifting and lowering motion. A grinding mechanism 8 is fixedly connected to the lower end of the Z-axis moving mechanism 7.

[0023] The Y-axis moving mechanism 5, located inside the gantry 4 on the worktable 2, adopts a linear guide structure similar to the X-axis moving mechanism 6. It moves along the width of the worktable 2 via a servo motor. A rotary clamping mechanism 9 is fixedly mounted on the moving platform of the Y-axis moving mechanism 5. This mechanism includes a 360-degree rotatable clamping table and a workpiece clamping device. The clamping table is driven by a servo motor for precise angular positioning, and the workpiece clamping device uses pneumatic or hydraulic clamping to accommodate the fixing needs of forklift accessories of different shapes and sizes.

[0024] In actual operation, the operator first fixes the forklift parts to be processed onto the rotary clamping mechanism 9. The control system, according to a preset program, coordinates the movement of the X-axis, Y-axis, and Z-axis moving mechanisms 7, enabling the grinding mechanism 8 to approach the workpiece along a predetermined trajectory. Simultaneously, the rotary clamping mechanism 9 can adjust the workpiece angle according to processing needs, achieving multi-angle, all-around grinding. The three-axis linkage, combined with the rotation of the rotary clamping mechanism 9, allows the grinding head to cover the processing requirements of all surfaces of the workpiece, eliminating the need for manual intervention to adjust the workpiece position.

[0025] This mechanism achieves highly efficient and automated grinding of forklift parts through the coordinated operation of a three-axis moving mechanism and a rotary clamping mechanism 9. The X, Y, and Z-axis moving mechanisms 7 provide precise three-dimensional positioning capabilities, while the rotary clamping mechanism 9 expands the workpiece's machining angle range. This structural design significantly improves the flexibility and automation of the grinding process, reduces manual intervention, and is particularly suitable for batch processing of complex-shaped forklift parts. The entire system is controlled by a CNC program, enabling rapid changeover processing of forklift parts of different specifications.

[0026] Example 3:

[0027] The grinding mechanism 8 in this embodiment includes a rotary adjusting cylinder 10, an assembly frame 11, and a grinding machine 12. The rotary adjusting cylinder 10 is fixedly connected to the end effector of the Z-axis moving mechanism 7 via a flange. The output shaft of the rotary adjusting cylinder 10 has a hollow design with an internal air passage, and is connected to an external air source via a rotary joint. The assembly frame 11 is made of high-strength aluminum alloy and has an L-shaped structure. Its vertical arm is fixedly connected to the output shaft of the rotary adjusting cylinder 10 by bolts, and its horizontal arm extends above the workpiece to be processed. The grinding machine 12 is mounted at the end of the horizontal arm of the assembly frame 11 via a quick-release mechanism, allowing for the replacement of grinding heads of different specifications according to processing requirements.

[0028] The rotary adjusting cylinder 10 adopts a double-acting cylinder structure with a built-in precision angle sensor, enabling precise angle adjustment from 0 to 180 degrees. A buffer device is provided between the cylinder piston rod and the mounting frame 11 to prevent impact when rotating to the final position. The horizontal arm of the mounting frame 11 is equipped with a guide rail structure, allowing the grinder 12 to be finely adjusted in the horizontal direction to accommodate the grinding needs of parts of different sizes. The power cord and control cord of the grinder 12 are arranged through the cable trays inside the mounting frame 11 and connected to the external control system.

[0029] During operation, the Y-axis moving mechanism 5 drives the rotary clamping mechanism 9 to deliver the workpiece to the working position. The X-axis moving mechanism 6 and the Z-axis moving mechanism 7 work together to position the grinding mechanism 8 onto the surface of the workpiece. The rotary adjusting cylinder 10 drives the assembly frame 11 to rotate according to a preset program, causing the grinding machine 12 to adjust to the optimal grinding angle. The grinding machine 12 rotates at high speed under pneumatic or electric drive, performing precision grinding on the surface of the workpiece. Throughout the process, the three-axis moving mechanism works in conjunction with the rotary adjusting cylinder 10 to achieve multi-angle, all-around automatic grinding operations.

[0030] The rotation axis of the rotary adjusting cylinder 10 is parallel to the movement direction of the Z-axis moving mechanism 7. This arrangement allows the grinder 12 to have the maximum adjustment range in the vertical plane. The L-shaped structure design of the mounting frame 11 ensures structural strength while providing sufficient operating space for the grinder 12. The quick-release mechanism uses a spring locking device, enabling rapid replacement of the grinding head to meet different process requirements. The angle sensor built into the rotary adjusting cylinder 10 provides real-time position feedback to the control system, achieving closed-loop control and ensuring the accuracy of the grinding angle.

[0031] During the polishing process, the control system automatically adjusts the angle and position of the polishing machine 12 according to a preset program, coordinating with the movement of the three-axis moving mechanism to achieve all-around polishing of complex curved surface parts. The rapid response characteristics of the rotary adjusting cylinder 10 enable the polishing machine 12 to adjust its angle in real time according to the shape of the parts, ensuring consistent polishing quality. Through coordinated control, the entire system significantly improves the automation level and processing efficiency of the polishing operation.

[0032] Example 4:

[0033] In this embodiment, the assembly frame 11 is fixedly mounted next to the grinder 12 with a chip blower 13. The chip blower 13 uses high-pressure airflow to promptly blow away metal debris generated during the grinding process from the processing area. The installation position of the chip blower 13 is precisely calculated to ensure that its outlet direction forms a specific angle with the rotation direction of the grinding wheel of the grinder 12, so that the airflow can effectively cover the entire grinding contact surface. When the grinder 12 is working, the chip blower 13 starts synchronously, and the generated high-speed airflow is sprayed along the tangential direction of the grinding wheel, quickly blowing away the debris attached to the workpiece surface and the gap between the grinding wheel.

[0034] The chip blower nozzle 13 is connected to an external air supply system via a flexible air tube. The air supply system is equipped with a pressure regulating valve and a filter, allowing adjustment of airflow pressure and flow rate according to different grinding conditions. The nozzle of the chip blower nozzle 13 is made of wear-resistant alloy material and has internal airflow guide grooves, causing the ejected airflow to form a fan-shaped diffusion surface, expanding the chip removal range. In the structural design of the mounting frame 11, the mounting base of the chip blower nozzle 13 is equipped with an angle adjustment mechanism, allowing operators to fine-tune the chip blowing angle as needed.

[0035] The operation of the chip blowing nozzle 13 is linked to the movement of the grinding machine 12. When the Z-axis moving mechanism 7 drives the grinding machine 12 to press down and contact the workpiece, the chip blowing nozzle 13 automatically opens; when the grinding is completed and the machine is lifted, the chip blowing nozzle 13 closes after a delay to ensure that residual chips are completely removed. The direction of the chip blowing airflow is optimized so that it does not interfere with normal grinding operations and effectively blows the chips to the preset collection area. An auxiliary dust suction port is also provided below the crossbeam of the gantry frame 4, which works with the chip blowing nozzle 13 to form an airflow circulation, further improving the chip removal efficiency.

[0036] Example 5:

[0037] The rotary clamping mechanism 9 in this embodiment includes a rotary motor 14 and a clamping head 15. The rotary motor 14 is directly driven by the clamping head 15 via a coupling. The rotary motor 14 is a servo motor, and its output shaft is fixedly connected to the clamping head 15 via a flange to ensure the stability and accuracy of power transmission. The clamping head 15 adopts a double-jaw chuck structure. The two jaws achieve synchronous opening and closing movements through an internal screw mechanism, which can firmly clamp forklift parts of different sizes. The clamping head 15 is equipped with a pressure sensor, which can monitor the clamping force in real time to prevent excessive clamping force from deforming the parts or insufficient clamping force from loosening the parts.

[0038] The rotary motor 14 is mounted on the moving platform of the Y-axis moving mechanism 5, and precise angle adjustment is achieved through a servo control system. When it is necessary to adjust the grinding angle of the part, the control system sends a command to make the rotary motor 14 drive the clamping head 15 to rotate, adjusting the part to the required angle. The rotation angle range is 360 degrees, which can meet the multi-angle grinding needs of various complex-shaped parts. During the rotation, the clamping head 15 remains stable and will not vibrate or shift due to rotation, ensuring grinding accuracy.

[0039] The dual-jaw chuck of the clamping head 15 is made of high-strength alloy steel with a hardened surface to improve wear resistance. Each jaw has anti-slip grooves on its inner side to increase friction with the fittings. The opening and closing stroke of the jaws can be automatically adjusted according to the size of the fittings.

[0040] The rotary motor 14 is equipped with an encoder and a brake. The encoder provides real-time feedback of the rotation angle information, and the brake can stop immediately after reaching the target angle to ensure the accuracy of angle positioning.

[0041] The rotary clamping mechanism 9 works in conjunction with the Y-axis moving mechanism 5. The Y-axis movement drives the clamping mechanism to move back and forth, while the rotary motor 14 adjusts the angle of the parts. Together, they enable precise positioning of the parts in multiple directions and angles. This design greatly improves grinding efficiency and reduces manual operation time, making it particularly suitable for batch processing of complex-shaped forklift parts.

[0042] In the actual operation, the operator first places the part to be processed on the clamping head 15, and the jaws automatically close to clamp the part. According to a preset program, the control system first sends the part to the grinding area via the Y-axis moving mechanism 5, and then controls the rotary motor 14 to rotate according to the required grinding surface angle, ensuring the grinding surface maintains the optimal contact angle with the grinding head. After grinding one surface, the rotary motor 14 automatically adjusts its angle, turning the next surface to be ground towards the grinding head, and this cycle continues until all surfaces are ground. The entire process is highly automated, requiring only one clamping operation to complete multi-angle grinding, significantly improving processing efficiency and accuracy.

[0043] Example 6:

[0044] In this embodiment, the gripping head 15 of the rotary clamping mechanism 9 is fixedly mounted with a rubber pad 16. This rubber pad 16 is made of a high-friction elastic material, and its surface has anti-slip textures. When the gripping head 15 clamps a forklift accessory, the rubber pad 16 can undergo elastic deformation, thereby increasing the contact area with the accessory's surface. The elastic properties of the rubber pad 16 allow it to adapt to accessory surfaces of different shapes, ensuring clamping stability.

[0045] In practice, the rubber pad 16 is installed on the clamping surface of the clamping head 15 by adhesive bonding or mechanical fixing. When the rotary motor 14 drives the clamping head 15 to rotate, the rubber pad 16 can provide sufficient friction to prevent the parts from sliding or shifting during rotation. Especially during high-speed rotary grinding, the anti-slip performance of the rubber pad 16 is particularly important, as it can effectively prevent the parts from loosening due to centrifugal force.

[0046] The design of the rubber pad 16 also takes wear resistance into account, ensuring that it will not wear out quickly due to frequent clamping during long-term use. At the same time, the replaceable design of the rubber pad 16 facilitates maintenance. When the rubber pad 16 wears to a certain extent, it can be easily replaced without replacing the entire clamping head 15.
