Technical Field

[0001] This utility model relates to the field of drilling equipment, specifically a fixing device for drilling holes in steel beams. Background Technology

[0002] For steel plates that require assembly, such as steel beams, car bodies, bridges, and buildings, leaving holes in the middle facilitates drilling and anchoring, ensuring their stability and safety. This is not only important in structural design and manufacturing but also improves overall performance and reduces costs in practical applications.

[0003] Existing methods for drilling holes in steel beams require operators to pre-measure and mark lines on the beam for pre-positioning before drilling. This involves a lot of repetitive work, resulting in low efficiency, and manual measurement inevitably introduces errors that can affect product accuracy. Therefore, those skilled in the art have provided a fixing device for drilling holes in steel beams to solve the problems mentioned in the background section. Utility Model Content

[0004] The purpose of this utility model is to provide a fixing device for drilling holes in steel beams, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A fixing device for drilling holes in steel beams includes a positioning plate, two side fixings, and an auxiliary drill. The positioning plate has multiple positioning holes evenly distributed on it. A steel beam is placed at the bottom of the positioning plate. Two side fixings are arranged between the positioning plate and the steel beam. The side fixings have a C-shaped structure. A locking nut is welded to the top of each side fixing. A locking bolt is threaded through the locking nut and the side fixings. A long strip of bottom side clamping plate is welded to the inner bottom surface of each side fixing. An auxiliary drill is slidably connected to the positioning holes of the positioning plate. The bottom of the auxiliary drill is a positioning tube, the outer diameter of which is equal to the inner diameter of the positioning hole. The inner diameter of the positioning tube is larger than the diameter of the drill bit. A drill rig fixing cylinder is slidably connected to the outer side of the auxiliary drill.

[0007] As a further embodiment of this utility model: a middle fixation is provided between the two side fixation devices. The structure of the middle fixation device is similar to that of the side fixation devices, except that the bottom of the middle fixation device is longer, and the bottom side clamp plate welded to the middle fixation device is located at one end of the inner side of the positioning plate.

[0008] As a further improvement of this utility model: the outer surface of the positioning plate is provided with three anti-disengagement holes, which are slidably connected to the locking bolts.

[0009] As a further improvement of this utility model: guide grooves are provided on both sides of the auxiliary drill, and two guide sliders are welded to the bottom inner side of the drill fixed cylinder, with the guide grooves and the guide sliders being slidably connected.

[0010] As a further improvement of this utility model, the bottom of the guide groove is connected to a limit block by an internal hexagon bolt.

[0011] As a further improvement of this utility model: the bottom outer side of the auxiliary punch is connected to an L-shaped cooling water pipe by a thread, and the cooling water enters the positioning tube after being snapped together with the pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this utility model, by fixing the positioning plate to the steel beam, the center of the positioning hole on the positioning plate corresponds one-to-one with the center of the target drilling position. The base of the magnetic drill is magnetically attached to the positioning plate, and the drill fixing cylinder of the auxiliary driller is slidably connected to the fixed position of the drill bit of the magnetic driller. The positioning tube at the bottom of the auxiliary driller is inserted into the positioning hole to guide the position of the drill bit of the magnetic driller. This reduces positioning time and improves work efficiency when drilling in batches. When the magnetic driller is working, the drill bit presses down, causing the drill fixing cylinder to slide and connect with the auxiliary driller. The drill bit does not contact the inner wall of the positioning tube during drilling, preventing damage to the positioning plate and improving its service life.

[0014] 2. In this utility model, by snapping together a pipe with flowing cooling water and a cooling water pipe, during the drilling process, the cooling water enters the auxiliary drill bit through the cooling water pipe to cool the drill bit, preventing the drill bit from losing strength due to high temperature, improving work efficiency, eliminating the need for manual cooling, and making it convenient to use.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-6 In this embodiment of the utility model, the fixing device for drilling holes in the steel beam includes a positioning plate 2, two side fixings 4, and an auxiliary drill 3. Multiple positioning holes 8 are evenly distributed on the positioning plate 2. A steel beam 1 is placed at the bottom of the positioning plate 2. Two side fixings 4 are arranged between the positioning plate 2 and the steel beam 1. The side fixings 4 have a C-shaped structure. A locking nut 6 is welded to the top of each side fixing 4. A locking bolt 7 is threadedly connected through the locking nut 6 and the side fixings 4. A long strip of bottom side clamping plate 9 is welded to the inner bottom surface of each side fixing 4. An auxiliary driller 3 is slidably connected to the positioning hole 8. The bottom of the auxiliary driller 3 is a positioning tube 11, which is inserted into the positioning hole 8 to guide the position of the drill bit of the magnetic drill. This reduces positioning time and improves work efficiency and accuracy when drilling in batches. The outer diameter of the positioning tube 11 is equal to the inner diameter of the positioning hole 8, and the inner diameter of the positioning tube 11 is larger than the diameter of the drill bit. A drill fixing cylinder 12 is slidably connected to the outside of the auxiliary driller 3 to prevent the positioning plate 2 from being damaged during the drilling process and to improve its service life.

[0024] Among them, a middle fixation 5 is provided between the two side fixation devices 4. The structure of the middle fixation 5 is similar to that of the side fixation devices 4. The difference is that the bottom of the middle fixation 5 is longer, and the bottom side clamping plate 9 welded to the middle fixation 5 corresponds to one end of the inner side of the positioning plate 2. The middle fixation 5 fixes the other end of the positioning plate 2, increasing the stability of the fixation.

[0025] Among them, the outer end of the positioning plate 2 is provided with three anti-disengagement holes 10. The anti-disengagement holes 10 are slidably connected with the locking bolts 7 to prevent the connection between the positioning plate 2 and the fixing device from loosening and causing slippage during the drilling process.

[0026] Among them, the auxiliary driller 3 is provided with guide grooves 16 on both sides, and two guide sliders 17 are welded to the bottom inner side of the drill fixed cylinder 12. The guide grooves 16 and the guide sliders 17 are slidably connected.

[0027] Among them, the bottom of the guide slide 16 is connected to the limit block 13 by the internal hex bolt 14 to prevent the drilling rig fixed cylinder 12 from falling out when it slides down, causing inaccurate positioning;

[0028] Among them, the bottom outer side of the auxiliary drill 3 is connected to an L-shaped cooling water pipe 15 by a thread. The cooling water enters the positioning tube 11 after being connected to the cooling water pipe 15 by a snap-fit. There is no need for manual cooling of the drill bit, making it convenient to use.

[0029] The working principle of this utility model is as follows: The side of the positioning plate 2 is aligned with the side of the steel beam 1. The locking nuts 6 on the top of the two fixing parts are rotated, causing the top of the locking nuts 6 to insert into the anti-disengagement hole 10. As the locking nuts 6 rotate, the bottom side clamps 9 on the two fixing parts are pulled to fit tightly against the bottom of the steel beam 1. Finally, the middle fixing part is installed on the positioning plate 2 in the above manner. The bottom side clamps 9 on the middle fixing part assist in fixing the positioning plate 2, making the connection more secure and stable. The positioning tube 11 on the auxiliary punch 3 is then inserted... Insert the drill bit fixing device into the positioning hole 8 to be drilled, and slide it into the drill fixing cylinder 12 of the magnetic drill. The base of the magnetic drill is magnetically connected to the positioning plate 2. Start the drill to drill. Under the downward pressure of the drill bit fixing device, the drill bit drills into the steel beam 1. The prefabricated positioning plate 2 is used to position the drill, improving drilling positioning efficiency and ease of use. During this process, the drill fixing cylinder 12 is slidably connected to the auxiliary driller 3, preventing the drill bit from contacting the inner surface of the positioning tube 11, thus extending its service life. Simultaneously, cooling water enters the auxiliary driller 3 through the cooling water pipe 15 to cool the drill bit, eliminating the need for manual cooling and making it convenient to use.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
