The digital display chamfering device for woodworking sawing machine is equipped with an adjustment gap mechanism on the guide rod, and the gap adjustment mechanism includes an opening on one side of the guide rod, and an anti-backlash member is installed in the opening , a spring screw is installed outside the anti-backlash structure, and an anti-backlash spring is arranged between the spring screw and the anti-backlash member.

As for the chamfering device for the digital display woodworking sawing machine, the number of the gap adjustment mechanisms is not less than two.

In the design of the utility model, since the guide rod and the base can rotate relatively, the connecting shaft is fixed on the guide rod, the capacitive angle sensor B is installed on the connecting shaft, and the display device is installed on the base that moves relative to the connecting shaft, allowing The grid angle sensor A is set on the lower side of the display device. Due to the relative rotation of the guide rod and the base, the capacitance grid angle sensors A and B also rotate relative to each other. The relative rotation angle can be displayed on the display device, and the buttons can realize Power on, power off, clear any position, lock the value of the liquid crystal display, and display the value of the liquid crystal display forward or reverse. The utility model adopts a high-precision angular displacement sensor, and its resolution is greatly improved. Using this instrument makes the reading more convenient. Accurate and time-saving.

Detailed ways

As shown in Figure 1, the digital display woodworking sawing machine chamfering device of the present utility model includes a liquid crystal display 1 with a control chip, a button 2, a capacitor angle sensor A3, a capacitor angle sensor B4, a connecting shaft 5, and a guide rod 6 , the base 7, the buttons 2 are arranged on the liquid crystal display 1, the guide rod 6 is arranged on the bottom of the base 7, the connecting shaft 5 is fixed on the guide rod 6, the guide rod 6 and the base 7 are connected together by the connecting shaft 5, and can rotate relatively , the capacitive angle sensor B4 is fixed on the connecting shaft 5, the liquid crystal display 1 is installed and fixed on the base 7, and the lower side of the liquid crystal display 1 is provided with a capacitive angle sensor A3, a capacitive angle sensor A3 and a capacitive angle sensor B4 It can be rotated relatively, and the button 2 is arranged on the liquid crystal display 1. When the base 7 and the capacitive angle sensor A3 and the capacitive angle sensor B4 connected to the rotating shaft 5 are relatively rotated, the relative rotation angle can be displayed on the liquid crystal display 1. , this angle is the angle between the guide rod 6 and the base 7. Button 2 can realize functions such as power on, power off, reset at any position, lock the value of the liquid crystal display, and display the value of the liquid crystal display positively or reversely.

A guide groove 8 is opened on the base 7 , and a mechanism for locking the base 7 and the guide rod 6 is arranged in the guide groove 8 . The mechanism for locking the base and the guide bar includes a push handle 13, a preload spring 14, a spring sleeve 15 and a locking hole arranged on the guide bar. The lower end of the push handle 13 is set in the lock hole, and 14 sets of preload springs Connected to the front end of the push handle 13, a spring sleeve 15 is arranged outside the pretension spring 14, and a flat washer 16 and a nylon washer 17 are arranged on the guide groove 8.
