Description

Technical Field

[0001] The utility model relates to the field of part drilling processing, in particular to a hand-held drilling tool. Background Art

[0002] In industrial manufacturing, many through holes on workpieces are formed by drilling with a drilling machine. In the process of drilling by workers using a drilling machine, one hand holds the end of the workpiece that does not need drilling, and extends the other end to the position below the drill bit of the drilling machine. At this time, the other hand turns on the switch of the drilling machine or presses down the drill bit of the drilling machine to perform the drilling operation on the position where the hole needs to be opened.

[0003] However, the above process has the following deficiencies: 1. The workpiece is not positioned at all, and it is prone to displacement during the drilling process, which causes the drilling position of the drill bit to deviate and even leads to drilling failure; 2. Single-hand operation by workers is prone to accidents, the workpiece cannot be held firmly, there are potential safety hazards, and industrial injuries occur frequently; 3. Only one part can be processed at a time, and the heat generated by drilling is transferred to the hand, which can easily burn the hand and cause scalding.

[0004] Therefore, there is an urgent need to provide a hand-held drilling tool with better safety, which makes the drilling operation more convenient and faster. Contents of the Utility Model

[0005] The purpose of the utility model is to overcome the deficiencies existing in the prior art, and provide a hand-held drilling tool. A wing bolt is used to lock the sheet metal (or other materials) to be drilled. A positioning mechanism and a drilling guide hole are reserved on the clamp, which facilitates loading and unloading operations and batch drilling, saves working hours, ensures safety, and realizes batch drilling.

[0006] The purpose of the utility model is achieved through the following technical scheme: this hand-held drilling tool comprises a main body, a bottom plate is arranged at the bottom of the main body, a plurality of guide holes are opened on the surface of the bottom plate, vertical plates are symmetrically fixed on both sides of the bottom plate, forming a "匚"-shaped structure; one side of the main body is open, for placing at least one part to be drilled, the other side of the main body is provided with a positioning plate, the positioning plate is welded and fixed with the vertical plates on both sides of the main body, closing this side of the main body; the top of the main body is open, a limiting plate is fixed at the opening, and each guide hole is exposed, a wing bolt is threadedly connected to the limiting plate, and the part to be drilled is pressed in the main body through the wing bolt.

[0007] As a further technical scheme, parts to be drilled are stacked in the main body sequentially from bottom to top.

[0008] As a further technical scheme, pre-drilled holes are opened on the surface of the part to be drilled, and when the part to be drilled is attached to the positioning plate for positioning, the pre-drilled holes are aligned with the guide holes one by one.

[0009] As a further technical solution, a screw hole is penetratingly opened on the limiting plate for detachably mounting a wing bolt.

[0010] The beneficial effects of the present utility model are: 1. The part fits against the positioning plate on one side of the main body to realize positioning, so that the part will not displace during the drilling process, the drilling position will not deviate, and the drilling accuracy is ensured; 2. The wing bolt is used to compress the part, so that no shaking occurs during processing, and workers no longer directly hold the part, ensuring the safety and reliability of processing; 3. The main body adopts a "匚"-shaped chute structure, which can accommodate a plurality of sheet metal parts, and can realize processing multiple parts at one time during drilling operation, improving the drilling processing efficiency.

[0014] Description of reference numerals: main body 1, bottom plate 11, guide hole 111, vertical plate 12, limiting plate 13, screw hole 131, positioning plate 14, wing bolt 2, part to be drilled 3, pre-drilled hole 31. Detailed Description of Embodiments

[0015] The present utility model will be described in detail below with reference to the accompanying drawings: Embodiment: as shown in the attached Figures 1-3 , this hand-held drilling tool includes a main body 1, a bottom plate 11, a guide hole 111, a vertical plate 12, a limiting plate 13, a screw hole 131, a positioning plate 14, a wing bolt 2, a part to be drilled 3 and a pre-drilled hole 31.

[0016] with reference to the attached Figure 1 , 2 , the bottom of the main body 1 is provided with a bottom plate 11, and eight guide holes 111 are opened on the surface of the bottom plate 11 (eight in this embodiment, other numbers are also possible, determined according to the specification of the part 3 to be drilled). Vertical plates 12 are symmetrically fixed on both sides of the bottom plate 11 (welding fixation can be adopted, or channel steel can be directly used for processing), forming a "匚"-shaped structure. One side of the main body 1 is open ( Figure 2 the right side in ), the part 3 to be drilled can be placed from the open mouth (multiple parts 3 to be drilled can be placed at one time to improve the drilling processing efficiency), and a positioning plate 14 is arranged on the other side of the main body 1 ( Figure 2(Left side of the middle) The positioning plate 14 is fixed to the upright plates 12 on both sides of the main body 1 by welding, thereby enclosing the main body 1 on that side.

[0017] Furthermore, such as Figure 1 As shown, the top of the main body 1 is open, and a limiting plate 13 is welded and fixed at the opening. During welding, it is necessary to ensure that each guide hole 111 is exposed above the limiting plate 13, that is, there is no obstruction. During drilling, the drill bit can smoothly enter from the open position at the top of the main body 1 without interfering with the limiting plate 13.

[0018] Furthermore, a screw hole 131 is drilled through the limiting plate 13 to facilitate the detachable installation of the wing bolt 2, such as... Figure 3 As shown, the wing bolts 2 can be used to press the part 3 to be drilled into the main body 1, preventing it from shaking during processing. Preferably, the parts 3 to be drilled are stacked sequentially in the main body 1 from bottom to top. Figure 3 The image shows the assembly structure of two parts 3 (sheet metal) to be drilled. In reality, there could be other numbers; the depth of the main body 1 can be adjusted.

[0019] Preferably, to facilitate processing, pre-drilled holes 31 can be made on the surface of the part to be drilled 3, so that when the part to be drilled 3 is fitted and positioned with the positioning plate 14, the pre-drilled holes 31 and the guide holes 111 are aligned one by one. The debris generated by drilling can be smoothly discharged through the opening at the top of the main body 1.

[0020] The working process of this utility model: During drilling, first loosen the wing bolt 2. Based on the depth of the main body 1, take an appropriate number of parts 3 to be drilled and stack them sequentially inside the main body 1 from bottom to top. Tighten the edges of the parts 3 against the positioning plate 14 to ensure close contact and complete positioning. Then, tighten the wing bolt 2 to press the parts 3 against the main body 1, completing the clamping and fixing. Align the drill bit with the pre-drilled hole 31 and start the drilling machine to begin drilling. Multiple parts can be processed at once. After all drilling is completed, loosen the wing bolt 2 again and remove the parts one by one.

[0021] It is understood that, for those skilled in the art, any equivalent substitutions or modifications to the technical solutions and inventive concepts of this utility model should fall within the protection scope of the appended claims.
