Description

Technical Field

[0001] The utility model belongs to the field of machining, and particularly relates to a drilling device for tuyere bricks. Background Art

[0002] The tuyere bricks in non-ferrous metal melting furnaces need to be drilled after the semi-finished products are dried. The hole diameter is relatively large, generally more than 40 mm, and the length is relatively long, resulting in a long drilling time. The holes in the tuyere bricks are generally inclined holes, and there is an angle less than 90 degrees between the depth direction of the holes and the length direction of the brick blank. During the drilling process, the brick blank needs to be placed obliquely, so there is an angle between the drilling direction and the length direction of the brick blank. Therefore, it is necessary to place a blocking object on the drilling machine to prevent the brick body from shifting, resulting in a deviation in the drilling position. However, there is no special blocking object that can be matched with the drilling machine currently. Because the drilling time is relatively long, the blocking object will shift in position or change in angle during the drilling process, which will cause the brick blank to shift, resulting in a deviation in drilling. Therefore, it is necessary to manually correct the position of the blocking object every once in a while during the drilling process, which affects the drilling efficiency. Moreover, it is very difficult to ensure that the placement position of the blocking object is the same every time during drilling, so it is impossible to ensure that the hole position angles of each brick are the same, which is not conducive to the subsequent use of the tuyere bricks.

[0003] In addition, in order to ensure the drilling quality, safety and other issues, the water drilling method is generally used for drilling. In this way, the brick blank will be soaked in water on the drilling machine for a long time, damaging the surface structure of the brick blank, causing large particles of the brick blank to be exposed, and affecting the appearance. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a drilling device for tuyere bricks. A matching positioning component is arranged on the drilling machine, which can reliably position the brick blank, avoid the displacement of the brick blank during drilling, and can also adjust the position and angle of the positioning component according to different drilling angle requirements to achieve the best positioning position, so as to ensure the drilling efficiency and the consistency of drilling.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is: a drilling device for tuyere bricks, including a drilling machine and a drill bit arranged at one end of the drilling machine. A plurality of locking bolts are arranged on the drilling machine, and the threaded section of the locking bolts is higher than the bed surface of the drilling machine, and the plurality of locking bolts are distributed on the left and right sides of the drilling direction of the drill bit;

[0006] It further includes a positioning component. The positioning component has a plurality of positioning rods. Each positioning rod is provided with a positioning hole for cooperating with the locking bolt for installation, and the positioning rod is fixed by cooperating with the locking bolt through a locking nut; the front end of the positioning rod is used to abut against the side surface of the brick blank, and the plurality of positioning rods respectively abut against the length side and the width side of the brick blank to position the brick blank.

[0007] In the positioning assembly, the number of positioning rods that abut against the length side of the brick blank is more than the number of positioning rods that abut against the width side of the brick blank.

[0008] In the positioning assembly, the positioning rods located on the left side of the drilling direction of the drill bit are the first positioning rods, and the positioning rods located on the right side of the drilling direction of the drill bit are the second positioning rods. A pull rod is connected between at least one first positioning rod and at least one second positioning rod.

[0009] The connection points of the pull rod with the first positioning rod and the second positioning rod are located between the positioning hole and the front end of the positioning rod.

[0010] Strip-shaped grooves are provided on the positioning rod, and a plurality of positioning holes are arranged at intervals along the length direction of the strip-shaped groove at the bottom of the strip-shaped groove.

[0011] The end face of the front end of the positioning rod is a plane.

[0012] The front end of the positioning rod is a connecting head with an arc-shaped end face, and a wedge-shaped head is rotatably arranged on the connecting head. The inclined surface on the wedge-shaped head serves as a positioning surface that fits in contact with the brick blank.

[0013] The wedge-shaped head and the connecting head are rotatably connected by a locking screw, and the wedge-shaped head is locked by a locking nut.

[0014] The bed surface of the drill press is provided with a plurality of vertically and horizontally intersecting grooves, and a plurality of drain holes are provided at the bottom of the grooves. The drain holes are connected to a water collecting tank below the drill press.

[0015] The locking bolts are arranged in the grooves, and the diameter of the locking bolts is smaller than the width of the grooves.

[0016] The beneficial effects of the present utility model are as follows: In the present utility model, a positioning assembly is installed on the drill press. The positioning rods of the positioning assembly form an angle less than 90 degrees with the drilling direction from the left and right sides of the drilling direction and abut against the side surfaces of the brick blank, so that the brick blank can be tightly abutted from the left and right directions of the brick blank, enabling the brick blank to maintain a fixed inclination angle, which is convenient for the drill bit to drill an inclined hole in the brick blank. After the positioning rods are positioned according to the size of the brick blank and the position and angle of the inclined hole, there is no need to adjust them during the drilling process, thus ensuring the consistency of the positions of the inclined holes on the brick blank, facilitating the subsequent use of the air vent bricks. At the same time, after adjusting the positioning assembly before the drilling starts, since there is no need to adjust it multiple times, the drilling efficiency can be improved.

[0017] The wedge-shaped head provided at the front end of the positioning rod of the present utility model can swing according to the position and angle of the placement of the brick blank, so that the positioning surface on the wedge-shaped head can be in surface contact with the side surface of the brick blank, thereby simplifying the adjustment process of the position and angle of the positioning rod, increasing the contact area and friction force between the positioning rod and the brick blank, and improving the reliability of positioning the brick blank.

[0018] The improvement of the drill press structure of the present utility model, the provided groove can store a certain amount of water, avoiding the mud and water generated during the drilling process from soaking the brick blank for a long time and causing the quality of the brick blank to decline; a drain port is arranged at the bottom of the groove, which can also drain the mud and water generated during the drilling process in time, further reducing the time for the brick blank to be soaked by water.

[0027] The following will further elaborate on the present utility model in conjunction with the drawings and embodiments, but it shall not be used as a basis for any limitation on the utility model.

[0028] Embodiment 1: As Figure 1 、 2 shown, a drilling and processing device for air eye bricks includes a drill press 1 and a positioning assembly arranged on the drill press 1. A drill bit for drilling is arranged at one end of the drill press 1, and the drill bit is not shown in Figure 1 and Figure 1The position of the arrow is the position of the drill bit, and the direction indicated by the arrow is the drilling direction of the drill bit. A plurality of locking bolts 4 are arranged on the drilling machine 1, and the threaded ends of the locking bolts 4 face upward and are higher than the plane of the drilling machine 1. The plurality of locking bolts 4 are distributed on the left and right sides of the drilling direction of the drill bit. The positioning assembly includes a plurality of positioning rods, and each positioning rod is provided with a positioning hole 8 for being mounted on the locking bolt 4 and being locked and fixed by a locking nut. An angle less than 90 degrees is formed between the length direction of the positioned positioning rod and the drilling direction of the drill bit. One end of the positioning rod facing the brick blank 6 abuts against the side surface of the brick blank 6, and the plurality of positioning rods respectively abut against the length side surface and the width side surface of the brick blank 6 to realize the positioning of the brick blank 6.

[0029] In this embodiment, three locking bolts 4 are arranged on the drilling machine 1, and correspondingly three positioning rods are arranged, including a first positioning rod 2 and two second positioning rods 5. The first positioning rod 2 is used to abut against the width side surface of the brick blank 6, and the two second positioning rods 5 abut against the length side surface of the brick blank 6. In other embodiments, the number of positioning rods can be adjusted according to actual situations, but it is necessary to ensure that the number of positioning rods for abutting against the length side surface of the brick blank is more than the number of positioning rods for abutting against the width side surface of the brick blank.

[0030] When the drill bit is drilling, the first positioning rod 2 and the second positioning rod 5 abut against the brick blank 6 to prevent the brick blank 6 from shifting, and ensure the directionality and consistency of drilling.

[0031] Further, in order to further ensure the reliability of the position of the positioning rod, a pull rod 3 is connected between the adjacent first positioning rod 2 and second positioning rod 5 to form a stable triangular structure, thereby preventing the first positioning rod 2 and the second positioning rod 5 from being squeezed and rotated outward during drilling. Hooks can be respectively arranged at both ends of the pull rod 3, and correspondingly, hanging holes cooperating with the hooks are arranged on the first positioning rod 2 and the second positioning rod 5. The number of hanging holes is more than one, and when connecting the pull rod 3, the connection between the hook and the hanging hole can be selected according to actual situations.

[0032] Furthermore, define the end of the positioning rod abutting against the brick blank 6 as the front end of the positioning rod. The connection points of the pull rod 3 with the first positioning rod 2 and the second positioning rod 5 are located between the positioning hole 8 and the front end of the positioning rod.

[0033] In order to adapt to the drilling operations of brick blanks of different sizes, a strip-shaped groove 7 is arranged on the positioning rod, and a plurality of positioning holes 8 are arranged at intervals along the length of the groove bottom. During use, the appropriate positioning hole 8 can be selected to be connected with the locking bolt 4 according to the brick blank size, drilling angle and the installation position of the positioning rod. For example Figure 1As shown, on the two second positioning rods 5, the positioning holes 8 for connecting with the locking bolts 4 are respectively located at different positions on the positioning rods. If the connection positions on the positioning rods still cannot be adapted to the brick blank through adjustment, it is necessary to select positioning rods of different lengths or adjust the positions of the locking bolts 4 on the drilling machine 1, so that the positioning rods can cooperate with the brick blank to reliably position the brick blank.

[0034] While setting the positioning component in this embodiment, the structure of the drilling machine is also optimized. For example, Figure 6 As shown, a plurality of vertically and horizontally intersecting grooves 11 are provided on the drilling machine 1. The length direction of the longitudinal grooves is the same as the length direction of the drilling machine, and the length direction of the transverse grooves is the same as the width direction of the drilling machine. A plurality of drain holes are provided at the bottom of each groove 11, and the drain holes are connected to the water collecting tank below the drilling machine. During the drilling process of the drill bit, the muddy water generated can be discharged from the drain holes in time, avoiding the brick blank being soaked in water for a long time. The locking bolt 4 is arranged in the groove 11, and the diameter of the locking bolt 4 is smaller than the width of the groove 11 to avoid affecting drainage.

[0035] Embodiment 2: In Embodiment 1, the positioning rod is a square rod, and the front end face of the positioning rod is a plane. When tightly positioning the brick blank, it is necessary to make the front end face of the positioning rod fit the side face of the brick blank to the greatest extent, so as to have a large contact area. On the one hand, it can maintain reliable pressing and positioning, and on the other hand, it can avoid damaging the brick blank. However, in actual use, due to different brick blank sizes and different hole angles, it is very difficult to find a suitable fixing angle for the positioning rod to make the front end of the positioning rod fit the side face of the brick blank. Therefore, it is necessary to adjust the position of the locking bolt to change the position of the positioning rod on the drilling machine to achieve the surface contact fit between the positioning rod and the brick blank, and the operation is relatively troublesome.

[0036] In order to simplify the operation and facilitate the realization of the surface contact fit between the front end of the positioning rod and the side face of the brick blank, on the basis of Embodiment 1, the structure of the front end of the positioning rod is improved in this embodiment: as Figures 3 - 5 shown, a connecting head 9 with an arc surface is provided at the front end of the positioning rod, and a rotatable wedge head 10 is connected to the connecting head 9. The inclined surface of the wedge head 10 is used as the positioning surface for fitting and contacting the side face of the brick blank. When adjusting the angle of the positioning rod, on the one hand, the positioning rod can be rotated around the locking bolt, and on the other hand, the wedge head 10 can rotate at the front end of the positioning rod, so as to achieve the surface contact fit with the side face of the brick blank. The whole adjustment process is more convenient than the method in Embodiment 1, and the inclined surface of the wedge head 10 can increase the contact area between the positioning rod and the brick blank, further ensuring the reliability of the positioning of the brick blank.

[0037] Further, the connection between the wedge head 10 and the connection head 9 can also be realized by a locking screw. After adjusting the positions of the positioning rod and the wedge head 10, the locking nut and the locking screw are cooperated to lock, so as to fix the position of the wedge head 10. Thereby, the swing of the wedge head during the drilling process can be avoided, and the reliable fixation of the brick blank can be further ensured.

[0038] The above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Those of ordinary skill in the art should understand that the specific implementation manners of the present invention can be modified or equivalently replaced by referring to the above embodiments. Any modification or equivalent replacement that does not depart from the spirit and scope of the present invention is within the protection scope of the claims pending for approval.
