Description

Technical Field

[0001] This utility model belongs to the field of grinding technology, and in particular relates to a multi-axis linkage profile grinding machine. Background Technology

[0002] The emergence of mechanical equipment and devices has brought convenience to people's industrial production, not only improving processing efficiency but also reducing workload. The components of mechanical equipment and devices include motors, screws, nuts, and gears. Grinding gears on a profile grinding machine is one of the processing steps. Grinding the gear surface can effectively remove burrs from the gear surface, preventing workers from being accidentally injured by burrs when handling gears by hand, increasing safety, and at the same time making the gear surface smoother and reducing wear during gear rotation.

[0003] A search revealed a profile grinding machine disclosed in patent publication number CN115870849A, relating to the field of profile grinding machine technology. It includes a mold grinding mechanism comprising a profile grinding machine. A base is fixedly connected to the bottom of the profile grinding machine, and a movable device is fixedly connected to the right side of the machine. A clamping device is fixedly connected to the outer wall of the movable device. A groove is also formed on the right side of the profile grinding machine. An airflow blowing mechanism is fixedly connected to the bottom of the machine, and a movable cleaning mechanism is fixedly connected to the right side. A collecting plate is positioned at the bottom of the workpiece to collect debris, ensuring the collection of debris generated during profile grinding and preventing its scattering. During the rotation of the elliptical block, the horizontal plate is compressed, causing the collecting plate to sway under the elasticity of the elastic plate, thus collecting the debris and accumulating it together.

[0004] However, profile grinding machines still have the following shortcomings in practical use: 1. First, a mounting frame is installed on the workbench. A hydraulic cylinder is installed on the inner top of the mounting frame. A grinding mechanism is installed at the piston rod end of the hydraulic cylinder's telescopic end. A clamping mechanism is also installed on the upper surface of the workbench. The operator uses the clamping mechanism to fix the position of the gear, starts the hydraulic cylinder, and the piston rod at the telescopic end of the hydraulic cylinder extends, causing the grinding mechanism to contact the surface of the gear and grind the gear. When it is necessary to grind the next gear, the machine needs to be stopped, the gear needs to be loaded and unloaded, and then restarted to grind the next gear. This increases the downtime and reduces the grinding efficiency of the gear. 2. Secondly, when it is necessary to grind another point of the gear, the staff needs to operate the clamping mechanism to open the gear, manually adjust the gear's orientation, operate the clamping mechanism to fix the gear's position, and operate the grinding mechanism to grind the gear again. This is a cumbersome operation and increases the workload of the staff.

[0005] To address these issues, we provide a multi-axis linkage profile grinding machine. Utility Model Content
