Drilling device and drilling method

Technical Field

The invention relates to the field of customized furniture production, in particular to a drilling device and a drilling method.

Background

With the continuous development of the decoration industry, customized furniture gradually enters the lives of people, and when people decorate houses, the customized furniture is selected more and more to meet the more personalized use requirements. In the manufacturing process of the customized furniture, a vertical hole and a horizontal hole are often required to be formed at the corners of the plate, and the vertical hole and the horizontal hole are matched with each other for use, so that the relative positions of the vertical hole and the horizontal hole are fixed. For the vertical hole, the vertical hole is convenient to open on the surface of the plate, and can be realized by using a conventional hole-opening tool. However, the horizontal hole is difficult to operate and difficult to position because the horizontal hole is formed on the narrow side of the plate. In the prior art, the horizontal hole is opened by a worker who needs to manually perform repeated measuring tape positioning, the operation is complex, the speed is slow, and for unskilled workers, the horizontal hole can be opened in even a few minutes, so that the efficiency is low.

a positioning mechanism for drilling a horizontal hole comprises a first connecting rod fixed horizontally and a positioning pin rotationally connected with the first connecting rod, wherein the positioning pin is connected with the first connecting rod through a torsion spring; the induction device faces to the side face of the positioning pin and is used for inducing the positioning pin; when no external force acts, the positioning pin is not in contact with the sensing device; when the locating pin rotates, the locating pin can be contacted with the sensing device.

Aiming at the problems of complex operation and low efficiency of forming a horizontal hole on a plate in the prior art, the invention provides the positioning mechanism for drilling the horizontal hole. The induction device is arranged on the side surface of the positioning pin and used for inducing the positioning pin. When no external force acts, the positioning pin is not in contact with the sensing device, namely no sensing signal is generated by the sensing device at the moment. When the locating pin rotated around first connecting rod, the locating pin contacted induction system, and induction system produced the sensing signal this moment to outside transmission signal carries out the trompil in horizontal hole. In the concrete working process of this scheme, the workman only needs to place the panel that has processed the vertical hole in the locating pin towards one side of induction system, promotes panel and removes to the locating pin direction, and the locating pin can rotate to inclination and mark on the panel surface this moment. Because the vertical hole has been processed on the panel, consequently along with the removal of panel, the locating pin can get into vertical hole at a certain instant, promotes panel reverse this moment again for the locating pin is close to the panel lateral wall, and at this moment, the locating pin can contact with induction system promptly. Because the fixed position of locating pin this moment, consequently need set up the position of horizontal hole also relatively fixed, so the workman only needs to set up the drill bit at the relative position that locating pin and sensor meet the department, induction system then drills once for sending a sensing signal to all set up the horizontal hole with the position of vertical hole relatively fixed at every turn, need not artifical measuring tape location again, realize the purpose of simple, convenient, the efficient sets up the horizontal hole promptly, very big improvement horizontal hole trompil efficiency.

(d) The sensing device (3) transmits a sensing signal to the control module (17), and the control module (17) controls the first driving device (12) to drive the pressing plate (13) downwards so that the pressing plate (13) is pressed on the surface of the plate (20) for fixing; then the control module (17) controls the second driving device (16) positioned in the middle and the second driving device (16) on one side to synchronously act, drives the two drilling devices (14) to move towards the direction of the table top, and simultaneously starts the two drilling devices (14) so that the two drill bit ends (141) respectively penetrate through the two through holes (15) to form two horizontal holes on the side surface of the plate (20);

(e) Resetting the first driving device (12) and the second driving device (16), and continuously pushing the plate (20) towards the pushing direction in the step (b) until the positioning pin (2) enters another vertical hole; reversely pushing the plate (20) to enable the plate (20) to move towards the direction of the induction device (3) until the positioning pin (2) is contacted with the induction device (3);

(f) The sensing device (3) transmits a sensing signal to the control module (17), and the control module (17) controls the first driving device (12) to drive the pressing plate (13) downwards so that the pressing plate (13) is pressed on the surface of the plate (20) to be fixed; and then the control module (17) controls the second driving device (16) positioned in the middle and the second driving device (16) on the opposite side in the step (d) to synchronously act, drives the two drilling devices (14) to move towards the direction of the table top, and simultaneously starts the two drilling devices (14), so that the two drilling ends (141) respectively penetrate through the two through holes (15) to form two horizontal holes on the side surface of the plate (20).
