Description

Technical Field

[0001] The present invention belongs to the technical field of abrasive belt grinding, and relates to a high-low multi-station abrasive belt grinding workstation. Background Art

[0002] Traditional abrasive belt grinding machines usually have only one station, and the process of loading and unloading often takes a relatively long time, directly affecting the use efficiency of the equipment. At the same time, for the grinding of flat workpieces, a flat workbench is often required, while for the grinding of shaped workpieces, a variable-position workbench is often required. These two situations are often difficult to be compatible, resulting in a large limitation in the application of grinding equipment. Summary of the Invention

[0003] In order to overcome the limitation that traditional abrasive belt grinding machines are often difficult to be compatible with flat workpieces and shaped workpieces, the present invention provides a high-low multi-station abrasive belt grinding workstation. The abrasive belt grinding equipment adopts a gantry structure, the abrasive belt device can be automatically lifted and lowered, is provided with a flat workbench and a variable-position workbench, and the two workbenches can shuttle back and forth, facilitating the rapid conversion of the working position.

[0004] The technical solution adopted by the present invention:

[0005] A high-low multi-station abrasive belt grinding workstation, comprising a double-abrasive-belt drive working device, a gantry, a left lead screw lifting servo mechanism, a right lead screw lifting servo mechanism, left and right legs, an abrasive belt grinding working device, a flat workbench, a variable-position workbench, ground rails, left and right side lifting guide rails, and an abrasive belt grinding working device guide rail; the double-abrasive-belt drive working device is installed on the gantry, the gantry is fixed on the ground through the left leg and the right leg, guide rails are installed on both sides of the gantry, the left lead screw lifting servo mechanism and the right lead screw lifting servo mechanism adopt a master-slave working mode to ensure the synchronization of actions on both sides, and drive the double-abrasive-belt drive working device to lift and lower on the gantry, so that the working height of the abrasive belt can be adjusted in real time according to the height of the workpiece; four ground rails are installed on the equipment base surface, the two outer ground rails are used for the movement of the flat workbench, and the two inner ground rails are used for the movement of the variable-position workbench. Since the width of the variable-position workbench is smaller than the inner width of the flat workbench, and the height of the variable-position workbench is lower than the bottom of the flat workbench surface, the variable-position workbench can freely shuttle under the flat workbench to convert the working position.

[0006] In order to further achieve the object of the present invention, the flat workbench can be upgraded to a liftable structure, so as to improve the ability of the variable-position workbench to pass under it and broaden the application range.

[0007] In order to further achieve the object of the present invention, a set of ground rails can be added and the length of all ground rails can be increased, and the number of workbenches can be increased from 2 to multiple, so as to further broaden the application range of the abrasive belt grinding workstation and improve the use efficiency.

[0008] The beneficial effects of the present invention are as follows:

[0009] 1. The double abrasive belt drive working device can move up and down on the gantry, so that the working height of the abrasive belt can be adjusted in real time according to the height of the workpiece;

[0010] 2. The variable-position workbench and the flat workbench can shuttle through each other and quickly switch the working position. During the grinding operation on one workbench, the other workbench can simultaneously perform the loading and unloading work, greatly improving the working efficiency;

[0011] 3. A high-low multi-station abrasive belt grinding workstation can be compatible with the grinding of flat workpieces and shaped workpieces at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The double abrasive belt drive working device 1 is installed on the gantry 2. The gantry 2 is fixed on the ground through the right leg 5 and the left leg 13. The left lifting guide rail 14 and the right lifting guide rail 15 are installed on both sides of the gantry 2; the left lead screw lifting servo mechanism 3 and the right lead screw lifting servo mechanism 4 adopt a master-slave working mode to ensure the synchronization of the actions on both sides, so as to drive the double abrasive belt drive working device 1 to move up and down along the left lifting guide rail 14 and the right lifting guide rail 15. Figure 3This is the state when the double-belt transmission working device 1 is raised to the highest position. Figure 4 This is the state when the double-belt transmission working device 1 is lowered to the lowest position.
