Description

Double-station horizontal axis circular table grinder

technical field

The utility model relates to a double-station horizontal-axis circular table grinder.

Background technique

A grinder is a machine tool that uses abrasive tools to grind the surface of a workpiece. Most grinding machines use high-speed rotating grinding wheels for grinding, and a few use other abrasive tools such as oil stones and abrasive belts and free abrasives for processing, such as honing machines, superfinishing machine tools, abrasive belt grinders, grinding machines and polishing machine etc.

Some workbenches of the existing grinding machines have a lifting structure, so when adjustment is required, the entire workbench must be adjusted by moving up and down, which consumes a lot of power, time and energy; and the existing grinders are single-station Operation, only after the current workpiece completes the grinding work, it can be replaced with a new workpiece for grinding, so that the time of workpiece grinding cannot be effectively used for other work, resulting in low work efficiency of the grinding machine.

The worktable translation mechanism includes a cylinder, the cylinder is connected with the workbench, and the lower part of the workbench is provided with a workbench guide rail. When working, the cylinder drives the workbench to move left and right along the guide rail of the workbench.

Preferably, the grinding wheel motor is connected to a current sensor, the current sensor is connected to a controller, the current sensor detects the current of the grinding wheel motor, and transmits the signal to the controller, and the controller controls the rotation of the guide rail lifting motor.

The beneficial effects of the utility model are:

When the workpiece is processed, the grinding wheel can move up and down and forward and backward, and the workbench does not need to move and lift, which reduces power loss; the overall structural performance is reliable, the operation is simple and easy, and the electromagnetic chuck can firmly absorb the workpiece on the workbench without complicated positioning methods; With double-station workbench, one station can be directly changed to another station to continue working after the grinding is completed, and the workpiece that has been ground at the previous station can be replaced with an unprocessed work piece in the gap between the work of another station. The workpiece can effectively use the time of workpiece grinding to prepare the workpiece and improve the working efficiency of the grinding machine.
