Description

Technical Field

[0001] The utility model relates to the technical field of drilling tools, in particular to a handle for a fitter to make holes. Background Art

[0002] In industrial production, many products need to be connected by rivets, such as aerospace products. Before connecting products with rivets, fitters need to manually make holes on the processing surfaces of the products so that the rivets can pass through.

[0003] The traditional hole-making method is that a fitter holds a drilling machine by hand and drills holes on the product surface. Before drilling, a template needs to be installed on the processing surface of the product, and template holes for marking the hole-making positions required for the product are preset on the template. The fitter drills holes in the product one by one according to the positions of the template holes, and then the hole-making work on the product can be completed.

[0004] However, when a fitter only holds the drilling machine by hand and drills holes on the product surface, the drill bit of the drilling machine is prone to vibration, resulting in excessive skew of itself, and the holes drilled and milled on the product are also skewed too much, so there is a problem of low hole-making quality. Summary of the Utility Model

[0005] In view of the above problems, the utility model provides a handle for a fitter to make holes.

[0006] In order to achieve the above invention purpose, the technical scheme adopted by the utility model is as follows:

[0007] There is provided a handle for a fitter to make holes, which is used to cooperate with a drilling machine and a template to drill holes in a product. The template is installed in parallel on the processing surface of the product, and template holes for marking the hole-making positions required for the product are preset on the template. The handle includes a handle body. One end of the handle body is provided with an installation hole penetrating along its thickness direction. A drill sleeve is arranged in the installation hole. A first through hole for restricting the skew amplitude of the drill bit is arranged through the drill sleeve. An annular boss for inserting into the template hole is arranged at one end of the drill sleeve at the first through hole.

[0008] Further, the drill sleeve is detachably connected in the installation hole. A flat opening is arranged on the outer wall of the drill sleeve. The inner wall of the installation hole contacts the side wall of the flat opening of the drill sleeve to restrict its rotation in the installation hole. A limiting member for restricting the drill sleeve from sliding out of the installation hole along the thickness direction of the handle body is arranged on the handle body.

[0009] Further, the limiting member includes a locking screw. A threaded hole adapted to the locking screw is arranged on the side wall of the flat opening of the drill sleeve. A second through hole for communicating with the threaded hole is arranged on the handle body. The locking screw passes through the second through hole and is threadedly connected in the threaded hole.

[0010] Further, the handle body includes a fixedly connected mounting block and a grip. The mounting hole and the second through hole are both provided on the mounting block. One end of the grip away from the mounting block is inclined in the direction away from the annular boss. When the annular boss is inserted into the template hole, the mounting block is parallel to the template surface, and an included angle space for the human hand to pass through is formed between the grip and the template.

[0011] Further, one end of the drill bushing is provided with an annular plate whose outer diameter is larger than the inner diameter of the mounting hole. The annular boss is coaxially arranged on the side of the annular plate away from the drill bushing. When the drill bushing is inserted into the mounting hole, the annular plate contacts the outer wall of the mounting block, and the second through hole communicates with the threaded hole.

[0012] Further, the mounting block and the grip are made of 7050 aluminum alloy material.

[0013] Further, the thickness of the grip is 5 mm.

[0014] The beneficial effects of the present utility model are as follows: Before drilling, the fitter needs to install the template parallel on the processing surface of the product, and template holes for marking the required drilling positions of the product are preset on the template; Subsequently, the fitter holds the handle body with one hand and inserts the annular boss into the template hole, and holds the drilling machine with the other hand, and inserts the drill bit through the first through hole of the drill bushing, then holes can be made on the processing surface of the product. The skew amplitude of the drill bit can be restricted through the first through hole on the drill bushing, which has the effect of improving the hole-making quality of the product.

[0019] In order to better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the accompanying drawings of the specification and specific embodiments.

[0020] An embodiment of the present application discloses a handle for a fitter to make holes. Refer to Figure 1, Figure 2 and Figure 3 , including a handle body 3. An installation hole 311 is penetrated through one end of the handle body 3 along its thickness direction. A drill bushing 4 is installed in the installation hole 311. A first through hole 41 for restricting the skewing range of the drill bit is penetrated through the drill bushing 4. An annular boss 5 for inserting into the template hole 21 is integrally fixed at one end of the drill bushing 4 at the first through hole 41.

[0021] In the embodiment of the present application, before drilling, a fitter needs to install the template 2 parallel to the processing surface of the product 1, and a template hole 21 for marking the drilling position required for the product 1 is preset on the template 2. Subsequently, the fitter holds the handle body 3 with one hand and inserts the annular boss 5 into the template hole 21, and holds the drilling machine with the other hand, and inserts the drill bit through the first through hole 41 of the drill bushing 4, then a hole can be made on the processing surface of the product 1. A handle for a fitter to make holes in the present application can restrict the skewing range of the drill bit through the first through hole 41 on the drill bushing 4, and has the effect of improving the hole-making quality of the product 1.

[0022] Furthermore, the drill bushing 4 is detachably connected in the installation hole 311. A flat port 42 is opened on the outer wall of the drill bushing 4. The inner wall of the installation hole 311 contacts the side wall of the flat port 42 of the drill bushing 4 to restrict its rotation in the installation hole 311. A limiting member 6 for restricting the drill bushing 4 from slipping out of the installation hole 311 along the thickness direction of the handle body 3 is installed on the handle body 3.

[0023] By the contact between the inner side wall of the installation hole 311 of the handle body 3 and the side wall of the flat port 42 of the drill bushing 4, the rotation of the drill bushing 4 in the installation hole 311 can be avoided, and the installation stability of the drill bushing 4 in the installation hole 311 is improved. During long-term use, the drill bit of the drilling machine is likely to cause wear to the drill bushing 4. The fitter can regularly remove the drill bushing 4 from the handle body 3 and replace it, and then the limiting member 6 can restrict the drill bushing 4 from slipping out of the installation hole 311.

[0024] Specifically, the limiting member 6 includes a locking screw 61. A threaded hole 43 adapted to the locking screw 61 is opened on the side wall of the flat port 42 of the drill bushing 4. A second through hole 312 for communicating with the threaded hole 43 is opened on the handle body 3. After the locking screw 61 passes through the second through hole 312, it is threadedly connected in the threaded hole 43.

[0025] In the embodiment of the present application, tightening the locking screw 61 can restrict the drill bushing 4 from slipping out of the installation hole 311. Through the design of the locking screw 61 and the flat port 42 of the drill bushing 4, the installation stability of the drill bushing 4 in the installation hole 311 can be further improved. In order to prevent the locking screw 61 from loosening automatically, a spring washer 8 is also sleeved on the locking screw 61.

[0026] Furthermore, the handle body 3 includes a mounting block 31 and a grip 32 that are fixedly welded. The mounting hole 311 and the second through hole 312 are both provided on the mounting block 31. One end of the grip 32 away from the mounting block 31 is inclined in the direction away from the annular boss 5. When the annular boss 5 is inserted into the template hole 21, the mounting block 31 is parallel to the surface of the template 2, and an included angle space for a human hand to pass through is formed between the grip 32 and the template 2.

[0027] In the embodiment of the present application, an included angle space is formed between the grip 32 and the template 2, which is more convenient for the fitter to reach out and hold the grip 32.

[0028] To facilitate the fitter to install the drill bushing 4 on the mounting block 31, an annular plate 7 with an outer diameter larger than the inner diameter of the mounting hole 311 is integrally fixed at one end of the drill bushing 4. The annular boss 5 is coaxially arranged on the side of the annular plate 7 away from the drill bushing 4. When the drill bushing 4 is inserted into the mounting hole 311, the annular plate 7 contacts the outer wall of the mounting block 31, and the second through hole 312 communicates with the threaded hole 43.

[0029] Furthermore, the mounting block 31 and the grip 32 are made of 7050 aluminum alloy material. This enables the mounting block 31 and the grip 32 to have sufficient metal strength and a lighter overall weight.

[0030] To facilitate the fitter to hold the grip 32, the thickness of the grip 32 is set to 5 mm.

[0031] The implementation principle of a handle for hole making by a fitter in the embodiment of the present application is as follows: Before drilling, the fitter needs to install the template 2 parallel on the processing surface of the product 1, and the template 2 is pre - provided with a template hole 21 for marking the drilling position required for the product 1; Subsequently, the fitter holds the handle body 3 with one hand and inserts the annular boss 5 into the template hole 21, and holds the drilling machine with the other hand, and inserts the drill bit through the first through hole 41 of the drill bushing 4, then the hole can be made on the processing surface of the product 1. The skew amplitude of the drill bit can be restricted through the first through hole 41 on the drill bushing 4, which has the effect of improving the hole - making quality of the product 1.
