Description

Technical Field

[0001] The utility model belongs to the technical field of target drilling machines, and in particular relates to a drill bit used for a target drilling machine. Background Art

[0002] Target drilling machines are commonly used for target drilling work on circuit boards, circuit boards, printed boards, film boards and membrane switches. Target drilling machines are accurate and fast in drilling holes on workpieces. The drill bit structure of the target drilling machine is simple, including a connecting rod and a drill bit. The drill bit is conical, and the bottom surface of the drill bit is connected to the connecting rod. When the target drilling machine drill bit is in use, it is fixed to the bottom fixing seat of the target drilling machine driver for drilling work. The existing target drilling machine drill bit and the fixing seat are generally fixedly connected by screws through and screwed together, and there is no pre-fixed structure during assembly. Therefore, it is difficult to accurately align the mounting holes during installation. The alignment can only be performed by rotating the drill bit multiple times, which makes it more troublesome to replace drill bits with different drilling diameters, and the operation is not easy. For this reason, we propose a drill bit for a target drilling machine. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figures 1 to 4 The utility model provides a technical solution: a drill bit for a target drilling machine, comprising a drill bit 2 arranged at the bottom end of a target drilling machine driving body 1, a convenient replacement mechanism is arranged between the drill bit 2 and the target drilling machine driving body 1, a protective mechanism is arranged at the bottom end of the drill bit 2, and the convenient replacement mechanism comprises: a connecting guide component, arranged at the connection between the target drilling machine driving body 1 and the drill bit 2; a limiting component, arranged on the inner side of the connecting guide component; a fixing component, arranged at the bottom end of the connecting guide component and connected with the target drilling machine driving body 1.

[0020] In this embodiment, preferably, the connecting guide assembly includes a mounting slot 100 provided at the bottom end of the target drilling machine driving body 1 and a mounting block 101 fixed to the top end of the drill bit 2. The mounting block 101 is engaged with the mounting slot 100 to facilitate the connection of the drill bit 2 with the target drilling machine driving body 1.

[0021] In this embodiment, preferably, a guide groove 200 and a guide block 201 fixed inside the mounting slot 100 are opened at the top of the mounting block 101, and the guide block 201 is engaged with the guide groove 200 to play a guiding role when the mounting block 101 is connected to the mounting slot 100.

[0022] In this embodiment, preferably, the limiting assembly includes limiting grooves 300 symmetrically opened on both sides of the inner wall of the installation slot 100 and built-in grooves 301 symmetrically opened on both sides of the installation block 101, and a limiting block 302 is arranged inside the built-in groove 301. The limiting block 302 is engaged with the limiting groove 300, so that the installation block 101 can be temporarily limited inside the installation slot 100, and the screw hole 500 and the fixing hole 501 can be accurately aligned. A spring 303 is connected between the limiting block 302 and the built-in groove 301, which can drive the limiting block 302 to reset and bounce up.

[0023] In the present embodiment, preferably, grooves 400 and through grooves 401 extending through the grooves 400 and connected to the limiting grooves 300 are symmetrically provided on both sides of the driving body 1 of the target drilling machine. A push rod 402 extending through the through grooves 401 and connected to the grooves 400 is provided inside the limiting grooves 300. A push plate 403 fixedly connected to the push rod 402 is provided inside the grooves 400. When the drill bit 2 is disassembled, the push plate 403 inside the groove 400 is pressed to drive the push rod 402 to slide inside the through grooves 401, and the limiting block 302 engaged in the limiting groove 300 is pushed to retract into the built-in groove 301, so that the limiting work on the installation block 101 can be released.

[0024] In this embodiment, preferably, the fixing assembly includes screw holes 500 symmetrically arranged at the bottom end of the target drilling machine driving body 1 and relative to both sides of the mounting slot 100, and fixing holes 501 symmetrically arranged through the bottom end of the mounting block 101. A fixing screw 502 is provided at the bottom of the mounting block 101, which passes through the fixing hole 501 and is connected to the screw hole 500. The fixing screw 502 is screwed and fixedly connected with the screw hole 500, so that the drill bit 2 and the target drilling machine driving body 1 can be installed and fixed.

[0025] In this embodiment, preferably, the protective mechanism includes a protective sleeve 600 mounted on the bottom end of the drill bit 2 and an elastic rubber block 601 symmetrically fixed on the inner wall of the protective sleeve 600. The end of the elastic rubber block 601 is squeezed and fit with the side of the drill bit 2, so that the protective sleeve 600 can be limitedly mounted on the end of the drill bit 2 for protection. Arc grooves 602 are symmetrically provided on both sides of the protective sleeve 600, which is convenient for the operator to insert his fingers into the arc grooves 602 to remove the protective sleeve 600.

[0026] The working principle and use process of the utility model are as follows: when the drill bit 2 needs to be installed and fixed to the target drilling machine driving body 1, the installation block 101 at the top of the drill bit 2 is first embedded in the installation slot 100 opened at the bottom end of the target drilling machine driving body 1, so that the guide slot 200 and the guide block 201 are slidably connected to play a guiding role, and the inclined surface on the upper side of the end of the limit block 302 is squeezed with the bottom end of the target drilling machine driving body 1, so that the limit block 302 squeezes the spring 303 to deform and shrink into the interior of the built-in slot 301, so that the installation block 101 can be completely inserted into the interior of the installation slot 101. At this time, the limit block 302 is reset from the interior of the built-in slot 301 under the action of the spring 303 and pops out to be inserted into the interior of the limit slot 300, and the limit block 302 pushes the push rod 402 inside the limit slot 300 to slide in the through slot 401 and embed into the interior of the groove 400, so that the installation The block 101 and the installation slot 100 are temporarily limited together, and the screw hole 500 is accurately aligned with the fixing hole 501, and then the fixing screw 502 is used to penetrate the inside of the fixing hole 501 from the bottom end of the installation block 101 and screwed and fixedly connected with the screw hole 500, so that the drill bit 2 and the target drilling machine driving body 1 can be installed and fixed, and when the drill bit 2 and the target drilling machine driving body 1 are separated, after the fixing screw 502 is unscrewed and the positioning is released, it is only necessary to press the pushing plate 403 inside the groove 400 to easily allow the limit block 302 to withdraw from the inside of the limit groove 300, so that the installation block 101 can be withdrawn from the inside of the installation slot 100 to complete the separation work. When the drill bit 2 is not in use, a protective sleeve 600 can be sleeved on the end of the drill bit 2, and the elastic rubber block 601 plays an extrusion and limiting role, so that the protective sleeve 600 is limitedly sleeved on the end of the drill bit 2 for protection.

[0027] Although the embodiments of the present invention have been shown and described (see the above detailed description for details), 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.
