[0022] For a clearer understanding of the technical features, objectives, and effects of the present utility model, the detailed implementation manner of the present utility model will now be described in detail with reference to the accompanying drawings.

[0023] As Figure 2-6 shown, the casting surface finishing device includes a mounting frame 1, a support frame 2 provided on the mounting frame 1, a driving roller 3 and a driven roller 4 rotatably connected to both ends of the support frame 2, a driving device provided on the mounting frame 1 and drivingly connected to the driving roller 3, and an endless abrasive belt 5 wound around the driving roller 3 and the driven roller 4.

[0024] It further includes a fixed bracket 10 connected to one side of the mounting frame 1 and the support frame 2 and a locking support mechanism 11 provided on the other side. The upper and lower ends of the locking support mechanism 11 are respectively detachably connected to the support frame 2 and the mounting frame 1.

[0025] For this casting surface finishing device, the connection between the mounting frame 1 and the support frame 2 is realized by the fixed bracket 10 and the locking support mechanism 11. Specifically, a fixed bracket 10 is provided on one side of the mounting frame 1 and the support frame 2, and the detachable connection between the mounting frame 1 and the support frame 2 is realized through the locking support mechanism 11 on the other side, thereby achieving stable support on both sides of the mounting frame 1 and the support frame 2. When it is necessary to replace the endless abrasive belt 5, by disassembling the locking support mechanism 11, the endless abrasive belt 5 can be installed from one side of the locking support mechanism 11, thus avoiding the need to remove the entire machine to replace the endless abrasive belt 5. The present utility model is convenient for replacing the abrasive belt, can effectively improve the replacement efficiency, and to a certain extent, improves the production efficiency.

[0026] The locking support mechanism 11 includes a base 111 provided on the mounting frame 1, a support seat 112 provided on the support frame 2, and a support column 113. A locking member is provided at the upper end of the support column 113, and a clamping joint 114 is provided at the lower end. The lower end of the support column 113 is detachably connected to the base 111 through the clamping joint 114, and the upper end of the support column 113 is locked to the support seat 112 through the locking member.

[0027] In this embodiment, the support seat 112 includes a substrate provided on the support frame 2, and an arc-shaped limiting groove is formed on the substrate. The locking member includes an adjusting nut 117 screwed on the support column 113 and a locking nut 118 provided at the upper end of the support column 113. The adjusting nut 117 presses against the lower surface of the substrate, and the locking nut 118 presses against the upper surface of the substrate.

[0028] The arc-shaped limit groove is adapted to the support column 113. After the support column 113 is installed, the support column 113 uses the adjusting nut 117 to perform appropriate height adjustment so that the two ends of the active roller 3 are at the same level, and the adjusting nut 117 is used to achieve support. At this time, the locking nut 118 is screwed to press the locking nut 118 on the base plate, thereby achieving the connection of the upper end of the support column 113.

[0029] In order to improve the stability of the connection, a plug-in slot is provided on the support seat 112, and a limiting column is arranged horizontally in the plug-in slot. The setting of the limiting column can effectively ensure that the support column 113 will not be detached from the arc-shaped limiting slot. Even if the correction device is used for a long time, a stable connection effect can be achieved.

[0030] A snap-in groove is provided on the base 111, and the snap-in joint 114 is snap-into the snap-in groove. In the present embodiment, the snap-in groove is T-shaped, and a convex rib adapted to the T-shaped groove is provided on the snap-in joint 114. Of course, in some other embodiments, it can also be other shapes such as U-shaped, and the snap-in joint 114 is flat for direct removal into the U-shaped snap-in groove. During installation, firstly, the snap-in joint 114 is inserted into the snap-in groove to fix the lower end of the support column 113, and then the support column 113 is stably supported by adjusting the adjusting nut 117 and screwing the locking nut 118. During disassembly, first screw the locking nut 118 and then screw the adjusting nut 117, and then move the snap-in joint 114 out of the snap-in groove to achieve disassembly.
