Description

Technical Field

[0001] The utility model relates to the technical field of machine tool tool assembly, in particular to a drill bit auxiliary assembly tool. Background Art

[0002] The drill bit is one of the commonly used tools in machine tools such as drilling machines and machining centers. Its structure mainly includes a tool holder, a collet, a nut and a drill bit. When using the machine tool or changing the tool, the drill bit needs to be assembled first and then installed on the machine tool spindle. The specific assembly process is: first use a wrench to unscrew the nut from the end of the tool holder to loosen the collet, then insert the shank of the drill bit into the collet, and finally use a wrench to tighten the nut to fix the position of the drill bit.

[0003] However, this assembly method has certain disadvantages: first, it consumes the energy and time of the staff, and the efficiency of disassembling and assembling the nut is slow; second, the force of manually tightening the nut is difficult to control. When the collet is clamped too tightly, excessive force will be applied to the drill bit, causing the drill bit to bend or break during processing; when the clamping force of the collet is insufficient, the drill bit is easy to loosen, thereby affecting the drilling effect.

[0004] Currently, there is no solution to the above-mentioned problem in the industry. Therefore, this application proposes a drill bit auxiliary assembly tool to solve the above-mentioned problem. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a drill bit auxiliary assembly tool, including a base, a column, a beam, a fixed plate, a movable plate, a lifting motor, a torque motor and a rotating component. The columns are longitudinally arranged on both sides above the base, and the beams are transversely arranged at the top of the columns on both sides. The fixed plate is arranged on the front side of the beam, and a slide rail is provided on the front side of the fixed plate. The back of the movable plate is connected to the slide rail for up and down sliding through a slider, and a nut is provided on the back of the movable plate. The lifting motor is arranged on the top of the fixed plate and is connected to the nut through a screw rod. The torque motor is arranged on the front side of the movable plate and is connected to the rotating component on its lower side.

[0006] Furthermore, the rotating assembly includes a hollow sleeve and a nut sleeve. The hollow sleeve is arranged longitudinally and the upper end is connected to the main shaft of the torque motor, and the lower end is connected to the nut sleeve. The nut sleeve is provided with a groove that is adapted to the shape of the nut.

[0007] Furthermore, a positioning sleeve is provided at a position inside the base corresponding to the rotating assembly, and a tapered groove that is adapted to the bottom contour of the tool handle is provided inside the positioning sleeve.

[0008] Furthermore, a buffer pad is provided on the base at a position outside the top of the positioning sleeve.

[0009] Furthermore, the torque motor is arranged on the front side of the movable plate through a connecting plate and bolts.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] The utility model uses a lifting motor to drive the torque motor and the rotating assembly to lift as a whole, and uses the torque motor to drive the rotating assembly to rotate, so as to assemble the drill bit and the tool handle on the base.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] like Figure 1-2As shown, the drill auxiliary assembly tool in this embodiment includes a base 1, a column 2, a beam 3, a fixed plate 4, a movable plate 5, a lifting motor 6, a torque motor 7 and a rotating component. The columns 2 are longitudinally arranged on both sides above the base 1, and the beams 3 are transversely arranged at the top of the columns 2 on both sides; the fixed plate 4 is arranged on the front side of the beam 3, and a slide rail 8 is provided on the front side of the fixed plate 4. The back of the movable plate 5 is connected to the slide rail 8 for up and down sliding through a slider; a nut is provided on the back of the movable plate 5, and the lifting motor 6 is arranged on the top of the fixed plate 4 and is connected to the nut through a screw rod 9; the torque motor 7 is arranged on the front side of the movable plate 5 through a connecting plate 10 and a bolt 11, and is connected to the rotating component on its lower side.

[0019] The rotating assembly includes a hollow sleeve 12 and a nut sleeve 13. The hollow sleeve 12 is arranged longitudinally and the upper end is connected to the main shaft of the torque motor 7, and the lower end is connected to the nut sleeve 13. The nut sleeve 13 is provided with a groove adapted to the shape of the nut.

[0020] like Figure 3 As shown, a positioning sleeve 14 is provided at a position inside the base 1 corresponding to the rotating assembly, and a tapered groove 15 that matches the bottom profile of the tool handle is provided inside the positioning sleeve 14.

[0021] A buffer pad 16 is also provided on the base 1 at the outside of the top of the positioning sleeve 14. The buffer pad 16 can be made of flexible materials such as rubber or silicone. On the one hand, when the knife handle is installed in the tapered groove 15, the buffer pad 16 can be pressed down appropriately to ensure that the bottom of the knife handle is in full contact with the tapered groove 15; on the other hand, materials such as rubber or silicone have a certain friction force, which can prevent the knife handle from rotating.

[0022] The working principle of this utility model is as follows:

[0023] Before assembling the drill bit, insert the tapered part of the bottom of the shank 17 into the tapered groove 15. The shank 17 and the tapered groove 15 are positioned and locked using the tapered surface positioning principle. When the two tapered surfaces are tightly combined, due to the inclination of the tapered surfaces, they will automatically adjust their positions to ensure that the mating surfaces are completely fitted, thereby achieving precise positioning. This design allows the tapered surfaces to automatically restore the precise fitting state when subjected to external force, ensuring the stability and repeatability of positioning.

[0024] During assembly, the lifting motor 6 drives the torque motor 7 and the rotating assembly to move downward, so that the nut sleeve 13 is sleeved on the nut 18, and then the torque motor 7 drives the rotating assembly to rotate in the opposite direction, loosening the nut 18, thereby loosening the collet 19, and then the lifting motor 6 drives the torque motor 7 and the rotating assembly to reset upward.

[0025] Insert the shank of the drill bit 20 into the collet 19 from above, and then the lifting motor 6 drives the torque motor 7 and the rotating assembly to move downward again, so that the nut sleeve 13 is sleeved on the nut 18, and at the same time the drill bit 20 is inserted into the hollow sleeve 12, and then the torque motor 7 drives the rotating assembly to rotate forward, tightens the nut 18, and thus locks the drill bit 20 through the collet 19, and finally the lifting motor 6 drives the torque motor 7 and the rotating assembly to reset upward.

[0026] The above method realizes the rapid assembly of the drill bit 20 and the shank 17. Compared with the traditional manual assembly method, it reduces the labor intensity of the staff and improves the assembly efficiency. At the same time, the torque motor 7 can accurately control the tightening force of the nut 18, thereby ensuring the assembly accuracy of the drill bit 20.

[0027] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
