Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of drilling equipment, in particular to a flange drilling tool. Background Art
[0002] In the field of mechanical processing, especially when it comes to drilling of disc-shaped workpieces such as flanges and discs, the fixation of the workpiece is crucial. The existing method is to install multiple clamping molds around the top of the processing template to clamp and limit the flange. This clamping method requires the staff to dock the flange with the processing template and then open and close the positioning in turn, which will take the user a certain amount of time to operate multiple clamping molds. Therefore, it is not convenient for the user to quickly limit the flange through the clamping mold. For this reason, we propose a flange drilling tool. Utility Model Content

[0021] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of 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.
[0022] See attached Figure 1-4A flange drilling tool comprises two overlappingly mounted clamps 1, which can be a flat-nose pliers capable of adjusting the inclination angle of a workpiece, or a common flat-nose pliers for adapting the drilling angle of a drilling rig, and a clamping unit 2 is also connected to the clamp 1, and the clamping unit 2 comprises a base 21, a side plate 22, a clamping member 3, a trough body 31, and a screw rod 32. Side plates 22 are mounted on both sides of the base 21, and the side plates 22 are in an inverted L shape. A cavity for accommodating a flange disc is formed between the base 21 and the side plates 22, and a clamping member 3 is arranged between the base 21 and the side plates 22, and the clamping member 3 is in a wedge shape, and two wedge-shaped clamping members 3 are symmetrically distributed on the bottom On the seat 21, one side of the clamping member 3 is connected to a screw rod 32 extending to the outside of the side plate 22. The screw rod 32 rotates to drive the clamping member 3 to slide toward the center position of the base 21. At this time, the wedge surface of the clamping member 3 abuts against the bottom of the flange disc to lift the flange upward, and the clamping member 3 is continuously slid until the top of the flange disc abuts against the inner wall of the side plate 22 to form a clamp. The whole process is simple and convenient, eliminating the need for the staff to dock the flange disc with the processing template and then open and close the positioning in sequence. A rectangular groove is also provided on the clamping member 3. When the drill bit drills through the flange disc, the groove provides space for the drill bit to prevent the drill bit from overextending and causing damage to the base 21.
[0023] In this embodiment, an extension plate 23 is further provided on the side plate 22. The extension plate 23 is located on the side plate 22 close to the flange and in the middle of the side plate 22. A positioning hole 24 is also opened on the extension plate 23, and the aperture of the positioning hole 24 is larger than the aperture of the drill bit.
[0024] Furthermore, a positioning block 25 for limiting the flange disc is installed on the cavity formed by the base 21 and the side plate 22. The side plate 22 and the positioning block 25 form a "U"-shaped structure, and the flange is placed from the "U"-shaped opening formed by the side plate 22 and the positioning block 25.
[0025] In this embodiment, a hand wheel 33 is sleeved on the screw rod 32 extending at the outer side of the side plate 22 . The rotation of the hand wheel 33 drives the screw rod 32 to rotate, thereby driving the clamping member 3 to slide toward the center position of the base 21 .
[0026] In this embodiment, a slideway 26 for accommodating the sliding movement of the clamping member 3 is further provided on the bottom of the base 21 , and the width of the slideway 26 is greater than the width of the clamping member 3 .
[0027] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.
