Description

Technical Field

[0001] The utility model relates to the technical field of door and window processing, in particular to a fixing device for milling a door and window frame. Background Art

[0002] Stainless steel doors and windows are used in areas with high corrosion protection requirements or for decorative furniture. When processing stainless steel doors and windows, the end faces of the stainless steel frames need to be milled so that the stainless steel frames can be fitted together. At the same time, when processing the stainless steel frames, clamps are required to assist in fixing them, thereby keeping the stainless steel frames in a stable state during the milling process. When the clamp is in use, the stainless steel frame needs to be placed inside the clamp for clamping and fixing. However, due to the diversity of shapes of stainless steel doors and windows, people need to process door and window frames of different shapes to suit doors and windows of different shapes. Therefore, when milling the end faces of the stainless steel frames, the door and window frames need to be adjusted to different milling angles.

[0003] However, the existing device is not convenient for adjusting the milling angle of the door and window frames, and some door and window frames are large and heavy, which makes it inconvenient for workers to move and adjust them. The operation is time-consuming and labor-intensive, which reduces work efficiency. Utility Model Content

[0010] Beneficial Effects

[0011] The utility model provides a fixing device for milling door and window frames, which has the following beneficial effects:

[0012] 1. A workbench is installed to place the door and window frames to be processed. The workbench is rotated and installed on the base. The rotating workbench can drive the door and window frames to rotate, so as to facilitate the adjustment of the milling angle of the door and window frames. A first cylinder is installed and started. The extension of the telescopic end of the first cylinder can drive the lifting seat to rise, thereby driving the ball to rise. When the ball rises to a top surface higher than the upper surface of the ball hole, it is convenient to move and adjust the position of the door and window frame. When the telescopic end of the first cylinder contracts, the lifting seat can be driven down, thereby driving the ball to drop down. At this time, the door and window frame can be placed on the workbench for clamping and fixing.

[0013] 2. A spring groove is provided for installing a spring. When the workbench rotates to the position where the positioning ball corresponds to the positioning groove, the spring stretches and drives the positioning ball to move into the positioning groove, which can limit the workbench to a certain extent and prevent the workbench from continuing to rotate. When the workbench continues to rotate, the positioning ball moves out of the positioning groove, and the spring is compressed. BRIEF DESCRIPTION OF THE DRAWINGS
