Description

Technical Field

[0001] This utility model relates to grinding equipment, specifically an automatic grinding production line for a gantry-type CNC surface grinder. Background Technology

[0002] Gantry robots are tools for transporting objects and are being used more and more widely.

[0003] Currently, the mainstream flexible automated logistics systems at home and abroad mainly consist of two methods: fully automated production systems composed of gantry robots transporting workpieces and automated production lines composed of robots for loading and unloading. Gantry robots transport parts at high altitudes, directly transporting the processed parts from one machine tool to another. Gantry robots also have auxiliary functions such as inter-process transportation, active loading and unloading, and material reversal. Due to their convenient, precise, and flexible transportation, relatively simple structure, and ease of combination and application, they are suitable for this purpose.

[0004] Surface grinding is a very important machining method, and CNC surface grinders are among the most widely used machine tools. They are widely used in various fields of industrial production, especially in industries such as mold making, tooling, automobiles, and bearing machinery manufacturing.

[0005] With labor shortages and the need to improve processing efficiency, automated machining of CNC surface grinders has become the mainstream of future development, and automated workpiece loading and unloading has become an important requirement for machine tools for manufacturing enterprises.

The Z-axis square steel moves along the Z-axis under the drive of the Z-axis transmission mechanism driven by the Z-axis servo motor.

[0011] 4. A Y-axis linear guide rail is slidably installed on the front end of the Z-axis square steel. The Y-axis linear guide rail is installed on the Y-axis square steel, and the gripper is installed at the lower end of the Y-axis square steel. The Y-axis square steel moves along the Y-axis under the drive of the Y-axis transmission mechanism driven by the Y-axis servo motor.

[0012] 5. The gripper performs X, Y, and Z axis linkage under the drive of each servo motor, thereby realizing automatic loading and unloading of workpieces on the worktable, as well as automatic positioning, flipping, and sequence transfer.

[0013] Furthermore, each transmission mechanism includes meshing gears and racks.

[0014] Furthermore, the grinding head is equipped with an online detection device, and a grinding wheel dresser is provided on one side of the worktable.

[0016] Furthermore, an auxiliary support for the crossbeam is provided between the CNC machine tool and the CNC surface grinder.
