Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution:

example (b):

as shown in fig. 1 and 2, a wood drilling positioning device comprises a drilling machine body 1, a positioning light source 2 and a reflector 3, wherein the drilling machine body 1 comprises a base 4, a support arm 5, a connecting block 6, a connecting arm 7 and a drill bit 8, the support arm 5 is vertically arranged on the base 4, a lifting groove is arranged on the support arm 5, the connecting block 6 is connected with the lifting groove in a sliding fit manner, the connecting arm 7 is arranged at one end of the connecting block 6, which is far away from the lifting groove, and the drill bit 8 is arranged at one end of the connecting arm 7, which is far away from the connecting block 6;

drill bit 8 is equipped with the light passageway 9 that runs through to its tip along its axis, 8 lateral walls of drill bit be equipped with the light inlet 10 of light passageway 9 intercommunication, location light source 2 sets up on the connecting block 6 of drill bit 8 with the synchronous up-and-down motion of

drill bit

8, 3 slopes of speculum set up in the light passageway 9 and with light inlet 10 corresponds, the light of location light source 2 by advance light inlet 10 get into through speculum 3 after the reflection with the coincidence of drill bit axis.

Wherein the light of the positioning light source 2 is obliquely incident into the light entrance hole 10. The inclination angle of the reflector 3 is determined according to the angle of the light entering the light inlet 10, for example, when the angle between the light entering the light inlet 10 (for convenience of description, it is referred to as incident light) and the horizontal plane is 60 °, the angle between the reflector 3 and the incident light is 15 ° (here, the installation principle of the reflector 3 is merely illustrated, and the angles of the positioning light source 2 and the reflector 3 can be freely set according to the reflection principle of the light). The positioning light source 2 may be, but is not limited to, a spotlight or a laser pointer. The drill 8 may be, but is not limited to, a hollow drill 8, and when the drill 8 is the hollow drill 8, the hollow portion thereof constitutes the light passage 9. When in use, if the chips enter the light to pass through, the chips in the light channel 9 can be cleaned through the light inlet hole 10 by means of blowing, flushing and the like.

The axis of the light inlet hole 10 is obliquely arranged, and the axis of the light inlet hole 10 is parallel to the incident light.

In fig. 1-3, the dashed lines represent red light and the arrows represent the direction of light propagation.

The working principle is as follows: the positioning light source 2 emits oblique and colored light (optionally one of visible light, here red light is selected, and the colored light is subsequently described as red light), which enters the light channel 9 through the light inlet 10. The red light entering the light channel 9 is reflected by the reflector 3 to change the light direction, so that the propagation direction is changed from inclined to vertical downward. And the vertical red light coincides with the drill bit 8 axis at this time. The vertical red light is vertically directed on the base 4 by the light tunnel 9. When wood (wood board, etc.) is put in, the position of the wood is adjusted to make the light spot formed by red light irradiation coincide with the circle center of the hole to be drilled, thus ensuring accurate positioning.

The utility model discloses a positioner need not to adjust 8 positions of drill bit, only needs to wait to process the accurate positioning that the timber position can realize the drilling position according to the light spot position adjustment, and positioning accuracy is high, is difficult to produce the deviation.

Further, as shown in fig. 2, a transparent baffle 11 is disposed in the light channel 9, and the transparent baffle 11 is disposed between the reflector 3 and the working end of the drill 8. The transparent baffle 11 that sets up is used for blockking the piece that produces when driling, avoids the piece to make the speculum 3 mirror surface produce filth and influence the reflection effect.

Further, as shown in fig. 3 and 4, the base 4 is provided with a pressure sensor 12, the pressure sensor 12 is connected with a controller 13, a signal output end of the pressure sensor 12 is connected with a signal input end of the controller 13, and a signal output end of the controller 13 is connected with a signal input end of the positioning light source 2. When the device is used, when the pressure sensor 12 detects a pressure signal indicating that wood is placed on the base 4 (the working table surface thereof), the pressure sensor 12 sends the pressure signal to the controller 13, and the controller 13 sends a control signal to the positioning light source 2 after receiving the pressure signal, so as to control the positioning light source 2 to be turned on. When the drilling is finished and the wood is taken away, the pressure signal detected by the pressure sensor 12 disappears, at this time, the pressure sensor 12 sends a no-pressure signal to the controller 13, and the controller 13 controls the positioning light source 2 to be turned off. The controller 13 is a conventional controller 13, and will not be described herein, and the principle of the controller 13 controlling the positioning light source 2 is common knowledge and will not be described herein. The manual and complex positioning light source 2 can be prevented from being opened and closed, and the working efficiency can be improved.

Further, as shown in fig. 3, an air gun 14 is arranged on the drilling machine body 1, and the air gun 14 is connected with a high-pressure air source. The lance 14 is a conventional device that may be, but is not limited to, a type FBD54-2 lance 14. The air gun 14 that sets up is used for clearing up light channel 9, and the piece that gets into the drilling production in the light channel 9 is ended in the drilling, then blows to light channel 9 by advancing unthreaded hole 10 through air gun 14, and then clears away the piece in it, avoids influencing location next time. The air lance 14 may also be used to clean debris from gaps in the worktop.

Further, as shown in fig. 3, a threaded hole is formed in the base 4, a screw rod 15 is connected to the threaded hole in an internal thread manner, and a pressing plate 16 is arranged at the top end of the screw rod 15. The screw rod 15 is connected with the pressing plate 16 in a rotating way. When the wood pressing plate is used, the pressing plate 16 is pressed on wood (wood board) by adjusting the depth of the screw 15 screwed into the threaded hole, and the wood pressing plate has a fixing effect on the wood.

The foregoing is illustrative of the preferred embodiments of the present invention, and it is to be understood that the invention is not limited to the precise forms disclosed herein, and that various other combinations, modifications, and environments may be resorted to, falling within the scope of the invention as defined by the appended claims. But that modifications and variations may be effected by those skilled in the art without departing from the spirit and scope of the invention, which is to be limited only by the claims appended hereto.
