Description

Technical field:

[0001] The utility model relates to the technical field of door and window corner assembly equipment, in particular to an automatic knife adjusting and locking device for a numerically controlled corner assembly machine. Background technology:

[0002] CNC corner assembly machines are mainly used for corner assembly of doors and windows. The working principle and overall layout of existing CNC corner assembly machines are relatively mature. In practical applications, in order to match different profiles, it is necessary to adjust the height of the two corner assembly knives in time.

[0003] At present, most of the adjustments of the cornering knives are made manually. For example, a Chinese patent discloses a cornering knife adjustment and clamping mechanism (authorization announcement number: CN219335728U). Its technical solution is to set a scale vertically on the knife holder, and then use a rotary column (with its own thread) to adjust vertically for each cornering knife separately. Then, each cornering knife is locked by a separate pressure block and a screw rod. This technical solution achieves the purpose of manually adjusting and locking the cornering knife. Although the above technical solution provides a feasible adjustment and locking method for the cornering knife, a large amount of manual operation is required in actual application. Not only is the adjustment and locking efficiency low, but the adjustment is also affected by human factors, and the accuracy is difficult to guarantee. For this reason, it is necessary to optimize and improve the adjustment and locking method of the cornering knife, so as to improve the adjustment accuracy and the adjustment efficiency at the same time.
