Electric screw driver drilling and positioning device

Abstract

The invention provides an electric screw driver drilling and positioning device. The electric screw driver drilling and positioning device comprises an electric screw driver and a positioning base, wherein the positioning base comprises a fixed support; a positioning support is of a right-angled frame structure, and a bayonet for vertically fixing the electric screw driver is arranged on the horizontal segment of the positioning support; a vertical sliding groove is formed in the vertical segment of the positioning support, and a rack is arranged on the side wall along the vertical segment of the positioning support; a guide rail convex block mutually matched with the vertical sliding groove is arranged inside the positioning base, a motor is further arranged inside the positioning base, and the motor is provided with a shaft gear mutually meshed with the rack for enabling the positioning support to move up and down along the guide rail convex block; the bottom of the positioning base extends outwards to form an inclined block with an inclined surface, and a laser transmitter is fixedly arranged on the inclined surface of the inclined block; an electromagnet is arranged at the bottom of the positioning base. The device can actively position the tool bit feeding position of the electric screw driver, so that the electric screw driver in the device can accurately capture the operating position in one time, and the work efficiency is greatly guaranteed.

Description

technical field [0001] The invention relates to the field of electric tools, in particular to an electric screwdriver drilling positioning device. Background technique [0002] At present, when the electric screwdriver tool in the prior art is in use, it is necessary to ensure the stable state of the electric screwdriver by hand-holding, and to drill or twist the screw by pushing the screwdriver head (drill bit) in the forward direction and pressing the bottom of the electric screwdriver. The method often cannot maintain the stable state of the electric screwdriver when the screwdriver head is rotating, resulting in unstable feeding, vibration, jumping, etc., which will easily cause the screwdriver head to deviate from the screw, or the drill bit will be unstable due to force and break; the existing electric screwdriver through The addition of an electromagnetic fixing device can often be fixed on the metal area next to the position where the hole needs to be drilled or scre...

[0002] At present, when the electric screwdriver tool in the prior art is in use, it is necessary to ensure the stable state of the electric screwdriver by hand-holding, and to drill or twist the screw by pushing the screwdriver head (drill bit) in the forward direction and pressing the bottom of the electric screwdriver. The method often cannot maintain the stable state of the electric screwdriver when the screwdriver head is rotating, resulting in unstable feeding, vibration, jumping, etc., which will easily cause the screwdriver head to deviate from the screw, or the drill bit will be unstable due to force and break; the existing electric screwdriver through The addition of an electromagnetic fixing device can often be fixed on the metal area next to the position where the hole needs to be drilled or screwed by electromagnetic adsorption, and the good fixation can ensure the stability of the screwdriver head (drill) feed and avoid the occurrence of screwdriver head (drill) due to (Drill bit) The feed is unstable, the vibration is too large or the jumping deviates from the screw or breaks, etc., but the defect of the existing electromagnetic drill is that it is often impossible to locate the operating position at the first time, and the operating position needs to be fixed before manual operation. For positioning, if the position is inaccurate, you need to release the fixed state, change the position and fix it again, and then perform manual positioning. There is a certain error range. It is often necessary to fix multiple times + manual positioning to achieve an accurate operating state, which seriously affects work efficiency.
