[0039] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0040] See Figures 1 to 3 As shown;

[0041] This embodiment provides a convenient auxiliary drilling device, which includes:

[0042] Main structural frame 1; and

[0043] The drill bit structure is movably connected to the slider guide rail 104 at the front end of the main structural frame 1 via a sliding component. The height of the drill bit structure can be adjusted via the sliding component.

[0044] A magnetic ring 6 is provided on the upper part of the drill bit structure;

[0045] The device has two laser emitting heads 703 that can rotate with the drill bit, and the rotation of the drill bit drives the two laser emitting heads 703 to rotate.

[0046] When the drill bit is perpendicular to the workpiece, the circles formed by the lasers emitted by the two laser emitters 703 are concentric circles.

[0047] Specifically, this embodiment discloses an auxiliary device that works with a tapping drill bit. Its main body is a main structural frame 1, and a slider guide rail 104 is set on the front side of the main structural frame 1. The drill bit structure is moved along the slider guide rail 104 by a sliding component, thereby controlling the height of the drill bit. In addition, this embodiment designs two laser emitting heads 703 that can rotate with the drill bit. When the drill bit rotates on the workpiece and performs tapping operations, the two laser emitting heads 703 will form two circles on the surface of the workpiece. When the two circles are in a concentric circle state, it indicates that the drill bit and the workpiece are perpendicular. Otherwise, they need to be in a non-perpendicular state.

[0048] Preferably, the main structural frame 1 of this embodiment includes: a base 101; a support beam 102 disposed perpendicularly to the base 101 on the base 101; and an upper sealing plate 103 fixed to the upper end of the support beam 102;

[0049] A slider guide rail 104 is provided between the upper sealing plate 103 and the base 101.

[0050] To facilitate operation by workers, the support beam 102 in this embodiment is fixed at one end near the base 101, and a handle mounting seat 2 is provided at the other end of the base; a manual pressing handle 201 is provided on the handle mounting seat 2. The manual pressing handle 201 in this embodiment is ergonomic and facilitates operation by workers.

[0051] As a preferred embodiment, in order to set up the above-mentioned two laser emitting heads 703, this embodiment has two technical means, namely:

[0052] The device is also equipped with a laser emitting structure 7 that works with the drill bit, and the laser emitting structure 7 has two laser emitting heads 703;

[0053] Alternatively, two laser emitters 703 are symmetrically arranged on both sides of the upper part of the drill bit.

[0054] Preferably, in this embodiment, the number of slider guide rails 104 is two;

[0055] The sliding component includes:

[0056] The slider 3 is slidably engaged with the slider guide rail 104. The slider 3 is made of linear bearing housing and is slidably engaged with both slider guide rails 104 simultaneously.

[0057] A sliding bearing seat 4 is provided on the front side of the slider 3, and a sliding guide post 8 is provided in cooperation with the sliding bearing seat 4.

[0058] The lower end of the sliding guide post 8 is equipped with a drill chuck 5, which is used to fix the drill bit.

[0059] This embodiment further defines the structure of the sliding assembly, which slides with two slider guide rails 104 via linear bearing seats to achieve height adjustment. Simultaneously, sliding guide posts 8 are mounted on two vertically arranged sliding bearing seats 4, and the lower end of the sliding guide posts 8 is fixed to the drill chuck 5. Finally, the drill bit and the magnetic ring 6 of this embodiment are fixed using the drill chuck 5.

[0060] When a laser emitting structure 7 that mates with a drill bit is used as the integrated carrier for two laser emitting heads 703, a through hole is machined in the middle of the laser emitting structure 7 in this embodiment, and multiple magnetic blocks 701 are evenly distributed on the inner wall of the through hole. The magnetic ring 6 at the top of the drill bit is connected to the laser emitting structure 7 through the magnetic blocks 701, and the drill bit can pass through the through hole and extend to the bottom of the laser emitting structure 7. Preferably, a power switch 702 for controlling the operation of the laser emitting head 703 is provided on the side of the laser emitting structure 7 in this embodiment.

[0061] During the design process, the through hole and the magnetic ring 6 parts can be designed as stepped surfaces to facilitate guidance and docking. The base 101 below the device fits against the vehicle body, and the external laser emission structure 7 is activated. The drill bit is aligned with the drilling position, and the device is driven by the power of the electric drill to perform the drilling function. At this time, the two laser emission heads 703 also rotate. When the two circles become concentric circles, they are considered to be perpendicular. This device ensures the accuracy of drilling.

[0062] The laser emitting device in this embodiment can be a conventional infrared emitter from the prior art. Similarly, just as the laser emitting structure 7 in this embodiment is fixed by magnetic adsorption, it can be connected to the device by fasteners. It is only necessary to ensure that the laser emitting structure 7 can be fixed at the drill bit position.

[0063] Secondly, when working in confined spaces, laser emitting devices cannot be used. Therefore, the two infrared laser emitting heads 703 in this embodiment can be directly integrated into the device and only need to be arranged on both sides of the drill bit.

[0064] The present invention provides a convenient auxiliary drilling device with the following advantages:

[0065] The device of this utility model, by setting two laser emitters 703, can form two circles as the drill bit rotates. When the two circles are concentric, it means that the drill bit and the workpiece are set perpendicularly, making it easier and more intuitive to observe the relative position of the drill bit and the workpiece. The device has low overall cost, is simple and convenient to operate, and the external handle is ergonomic, reducing labor intensity, saving time and effort, and improving production efficiency and safety.

[0066] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
