Abstract
Description
Technical Field
[0001] This utility model relates to the field of door and window processing, and in particular to a grinding device for the edges and corners of metal door and window production. Background Technology
[0002] In the production of metal doors and windows, edge and corner grinding is a crucial process to ensure a smooth product appearance and eliminate burrs. Existing technologies often employ handheld angle grinders, requiring operators to manually hold the workpiece and perform grinding. This has the following drawbacks: low positioning accuracy: manual clamping easily leads to workpiece displacement, affecting grinding uniformity, especially for large door and window workpieces, making it difficult to guarantee edge and corner consistency. Based on this, we propose an edge and corner grinding device suitable for metal door and window production. Utility Model Content
[0003] To address the technical problem of low positioning accuracy in existing technologies, this utility model provides a grinding device for the edges and corners of metal doors and windows.
[0004] This utility model is achieved by the following technical solution: a grinding device for the edges and corners of metal doors and windows, comprising a device body, a grinding positioning mechanism, and a grinding mechanism;
[0005] A mounting base is provided at the bottom of the main body of the device, and an installation platform is installed above the mounting base;
[0006] The grinding and positioning mechanism is installed above the installation platform and includes a connecting table, a reciprocating motor, a rotating screw, a moving positioning plate, and a fixed plate. The connecting table is fixedly connected to the installation platform, the reciprocating motor is installed on one side of the connecting table, and the output shaft of the reciprocating motor is coaxially connected to the rotating screw. The bottom of the moving positioning plate is sleeved on the surface of the rotating screw, and the fixed plate is installed opposite to one side of the moving positioning plate.
[0007] The metal door and window workpiece is placed in the clamping groove of the moving positioning plate. The workpiece is fixed by adjusting the clamping groove spacing. The reciprocating motor is started to drive the rotating screw to rotate, which drives the moving positioning plate to move horizontally along the guide groove of the fixed plate. The moving positioning plate and the fixed plate clamp and position the metal door and window workpiece, realizing the precise front and rear positioning of the workpiece.
[0008] As a further improvement to the above solution, anti-slip rubber pads are provided on the inner sides of both the moving positioning plate and the fixed plate to prevent damage to the metal door and window workpieces during clamping.
[0009] As a further improvement to the above solution, the grinding mechanism includes support columns, a movable rod connected between two sets of support columns, a movable block sleeved on the surface of the movable rod, a grinding machine mounted on the movable block, a handle on the grinding machine, and a grinding disc on the grinding machine.
[0010] As a further improvement to the above solution, by pressing down on the handle, the tilt angle of the grinding disc is adjusted, and the grinding machine is started to grind the edges and corners, thus achieving the purpose of grinding the edges and corners of metal door and window workpieces.
[0011] As a further improvement to the above solution, a movable block is fitted onto the surface of a movable rod, and the movable block slides on the surface of the movable rod to adjust its position. The operator holds the handle and pushes the movable block to slide laterally along the movable rod, causing the grinder to cover the corner areas of the workpiece.
