Description

Technical Field

[0001] This utility model relates to the field of modular housing processing technology, specifically to an auxiliary tooling for drilling holes with an electric drill. Background Technology

[0002] Common modular shelters are typically hexahedral or chamfered structures, both of which require drilling holes in the roof. In daily production, these holes are drilled from bottom to top, requiring workers to use a hand-held electric drill and rely on arm strength to complete the drilling – a very strenuous and inefficient process. Furthermore, hand-held drills often produce angled holes, causing unnecessary problems for subsequent installation.

[0003] In addition, if the working space is relatively narrow, it is difficult for construction workers to adjust to a suitable posture for exerting force, which seriously affects the drilling quality.

[0004] Therefore, there is an urgent need for an auxiliary device specifically designed for drilling holes in the top of modular shelters, so as to enable the drilling operation to be completed quickly and accurately. Utility Model Content

[0028] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. Detailed Implementation

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0030] like Figures 1 to 7 As shown, this embodiment provides an auxiliary tooling for drilling with an electric drill, including a first sliding seat 1 and a second sliding seat 2, which slide in a vertical direction.

[0031] Specifically, the first sliding seat 1 is provided with a slide rail 11 extending in the vertical direction, and the second sliding seat 2 is provided with a sliding strip 21 extending in the vertical direction fixed on the side facing the slide rail, and the sliding strip 21 and the slide rail 11 form a sliding engagement.

[0032] In order to achieve a stable sliding connection in the vertical direction, in this embodiment, slide 11 is a dovetail slide and slide bar 21 is a dovetail slide bar.

[0033] Meanwhile, the first sliding seat 1 is provided with a sliding drive mechanism, which is used to drive the second sliding seat 2 to move up and down relative to the first sliding seat 1.

[0034] The sliding drive mechanism is specifically configured as follows: A rack 22 extending vertically is embedded and fixed on the sliding bar 21 facing the slide rail side. A window 12 is correspondingly opened on the slide rail 11 facing the rack, and the window 12 is located in the middle position of the slide rail 11 in the vertical direction. A gear rotation space is provided inside the window 12. A horizontal channel 13 is provided horizontally through the gear rotation space, and a rotating shaft 3 that rotates and engages with it passes through the horizontal channel 13. A gear 4 is fixedly fitted on the rotating shaft 3 at a position corresponding to the gear rotation space. The gear 4 protrudes outward from the window and meshes with the rack 22.

[0035] For ease of operation, one end of the rotating shaft 3 extends outward from the first sliding seat 1, and a rotating handwheel 5 is provided at the extended end of the rotating shaft 3.

[0036] When the sliding drive mechanism is working, rotating the handwheel 5 in either the forward or reverse direction drives the gear 4 to rotate via the rotating shaft 3, which in turn drives the rack 22 to move up and down, thereby driving the second sliding seat 2 to move up and down. A fixing mechanism for fixing the electric drill is provided on the second sliding seat 2, and the electric drill is fixed to the second sliding seat 2 by the fixing mechanism.

[0037] Specifically, the fixing mechanism is located on the side of the second sliding seat away from the first sliding seat. The fixing mechanism includes a support plate 61 fixed at the bottom and two clamping plates 62 arranged at intervals in the vertical direction above the support plate 61. The clamping plates 62 are provided with externally open clamping grooves, and clamping clamps 63 are detachably fixed at the clamping grooves by screws.

[0038] In order for the auxiliary tooling to adapt to different height scenarios, the first sliding seat 1 needs to be able to be raised and lowered, so a lifting rod 7 was designed for this purpose.

[0039] The lifting rod 7 consists of a vertical section, an arc-shaped connecting section, and a horizontal section. The vertical section has external threads, and the horizontal section is fixedly connected to the first sliding seat 1. The lifting rod 7 is mounted on the base 9 via a lifting mechanism, which drives the lifting rod 7 to move up and down relative to the base 9.

[0040] Specifically, the lifting mechanism includes: an internally threaded sleeve 8 extending vertically fixed on the base 9; the vertical section of the lifting rod 7 is threadedly connected to the internally threaded sleeve 8; the lifting rod 7 is adjusted by rotation, thereby driving the first sliding seat 1 to lift.

[0041] The working principle of this utility model is as follows:

[0042] First, place the electric drill on the support plate 61 of the second sliding seat and align it with the slot on the clamp plate 62. Secure the electric drill firmly with the clamp 63. Then, adjust the height of the lifting rod 7 according to the drilling position so that the drill bit is close to the drilling position. Next, start the electric drill, align the drill bit with the drilling coordinate position, and turn the rotating handwheel 5. The rotating handwheel 5 drives the gear 4 to rotate through the rotating shaft 3, which in turn drives the rack 22 to move up and down, thereby driving the electric drill on the second sliding seat 2 to move up and down, completing the drilling operation.

[0043] This invention enables quick and accurate bottom-up drilling, improving drilling quality and efficiency, and facilitating subsequent assembly work. It is also suitable for bottom-up electric drill drilling in confined spaces.
