Technical Field

[0001] This invention belongs to the field of liner processing technology, and particularly relates to a drilling device for installing liners in a steel ball mill. Background Technology

[0002] During the liner processing, in order to securely fix the liner to the cylinder, it is usually necessary to drill holes in the surface of the liner using a drilling device to install bolts and other fasteners. However, traditional drilling devices often use a single drill bit design, which leads to low drilling efficiency when drilling a large number of liners. Summary of the Invention

The mounting cavity includes a square rod inside, with a lower mounting post fixedly connected to the bottom of the square rod and fitting against the inner wall of the second circular hole. The drill bit is fixedly connected to the bottom of the lower mounting post. The cavity also includes a drive mechanism for simultaneously rotating the drill bit corresponding to each square rod, and an annular limiting groove on the square rod. Inside the mounting cavity is a pair of abutting blocks that move simultaneously or in opposite directions. When the two abutting blocks move relative to each other, they are separated from the inner wall of the annular limiting groove. When the two abutting blocks move in opposite directions, they are fitted against the inside of the annular limiting groove.

[0005] Preferably, a pair of support blocks are fixedly connected to the top of the processing table below the mounting shell, and an L-shaped mounting bracket is fixedly connected to the opposite side of each of the two support blocks. A drive unit is mounted on the L-shaped mounting bracket, and an abutment plate that slides along the top of the support block is fixedly connected to the output end of the drive unit.

[0006] Preferably, an L-shaped fixing frame is fixedly connected to the top of the processing table, a second drive unit is installed on the L-shaped fixing frame, a trapezoidal connecting frame is fixedly connected to the output end of the second drive unit, and the bottom of the trapezoidal connecting frame is fixedly connected to the top of the mounting shell.

[0007] Preferably, a pair of L-shaped limiting blocks are fixedly connected to the back of the mounting shell, and the L-shaped limiting blocks are provided with concave grooves that fit with the surface of the L-shaped fixing frame.

[0008] Preferably, the driving mechanism includes a driving part three mounted on the top center of the mounting housing. The output end of the driving part three is fixedly connected to a large circular gear that rotates inside the mounting cavity. The surface of the large circular gear is connected to a plurality of small circular gears that are adapted to and correspond to the circular hole one. The top of the small circular gears is connected to the top wall of the mounting cavity through a bearing. The small circular gears are connected to a square groove that fits against the surface of the square rod.

[0009] Preferably, a pair of vertical plates are fixedly connected to the bottom wall of the mounting cavity, and a horizontal moving rod is slidably connected to each vertical plate. One end of the horizontal moving rod is fixedly connected to the abutment block, and an annular block is fixedly connected to the surface of the horizontal moving rod. A first spring sleeved on the horizontal moving rod is fixedly connected between the annular block and the vertical plate. A semi-circular connecting block is fixedly connected to the other end of the horizontal moving rod, and a toggle mechanism is linked between the two semi-circular connecting blocks.

[0010] Preferably, the actuating mechanism includes a drive unit four mounted on the center of the bottom wall of the mounting cavity, a circular rotating block fixedly connected to the output end surface of the drive unit four, and a pair of circumferentially distributed arc-shaped actuating blocks fixedly connected to the surface of the circular rotating block.

[0011] Preferably, when the arc-shaped actuating block is in contact with the semi-circular connecting block, an air guide tube is attached to the surface of the annular block. One end of the air guide tube is fixedly connected to one side of the vertical plate, and the other end of the air guide tube is fixedly connected to a circular sealing plate sleeved on the horizontal moving rod. An air supply pipe is connected to the air guide tube, and one end of the air supply pipe that passes through the outside of the mounting shell is provided with an abutment that fits against the top of the circular block.

An L-shaped limiting plate that extends through to the outside of the fixed shell is fixedly connected to the movable plate.

[0013] Preferably, a pair of extension plates are fixedly connected to the bottom of the fixed shell, and the bottom of the extension plates are fixedly connected to the top of the mounting shell.

[0014] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0015] This invention enables simultaneous dual-hole drilling of the liner plate using two drill bits mounted on the housing, significantly improving the efficiency of drilling batches of liner plates. Furthermore, the design of the contact block and the annular limiting groove not only stabilizes the drill bit structure during drilling, ensuring efficient and stable drilling operations, but also allows for quick and efficient drill bit replacement through a simple drive operation when a damaged drill bit needs to be replaced. Whether it is a single drill bit or two drill bits, the replacement can be performed simultaneously, greatly improving the convenience of maintenance.

[0016] More importantly, when the contact block is in contact with the annular limiting groove, the gas inside the air guide cylinder is compressed by the sliding annular block and transported to the inside of the fixed shell through the air supply pipe. This is used to drive the moving plate and the L-shaped limiting plate to further stabilize the drill bit structure, improving drilling accuracy and operational stability. When the contact block is disengaged from the annular limiting groove, the drive mechanism can also rotate the two drill bits synchronously and generate a slight vibration force through the intermittent contact of the contact block, effectively removing debris from the surface of the drill bit and preparing for the next batch of drilling operations, further improving overall operational efficiency.

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement it based on the description.

[0032] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0033] In the description of this invention, the terms "lateral", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0034] Example 1: Refer to Figure 1 , Figure 3 and Figure 12 A drilling device for mounting liner plates in a steel ball mill includes a processing table 1 and a lifting mounting shell 2 mounted above the processing table 1. The mounting shell 2 is equipped with a rotatable drill bit 3. Below the mounting shell 2, there is a pair of support blocks 4 fixedly connected to the top of the processing table 1. On the opposite side of each of the two support blocks 4, there are L-shaped mounting frames 41 fixedly connected. A drive unit 42 is mounted on the L-shaped mounting frame 41. The output end of the drive unit 42 is fixedly connected to an abutment plate 43 that slides along the top of the support block 4. An L-shaped fixing frame 5 is fixedly connected to the top of the processing table 1. A drive unit 51 is mounted on the L-shaped fixing frame 5. The output end of the drive unit 51 is fixedly connected to a trapezoidal connecting frame 52. The bottom of the trapezoidal connecting frame 52 is fixedly connected to the top of the mounting shell 2. A pair of L-shaped limiting blocks 53 are fixedly connected to the back of the mounting shell 2. The L-shaped limiting blocks 53 have concave grooves 54 that fit against the surface of the L-shaped fixing frame 5.

[0035] In use, the liner to be drilled is placed on two support blocks 4. Since the top of the support block 4 is designed according to the shape of the liner placement surface, it can provide stability when the liner is in contact with the top of the support block 4. Then, the corresponding drive unit 42 on the two support blocks 4 is activated to push the connected abutment plate 43 to slide along the top of the support block 4, so that the liner to be drilled is stably fixed between the two support blocks 4. After the liner is fixed, the drive unit 51 using a cylinder is driven to move down in conjunction with the mounting shell 2, so that the drive mechanism installed on the mounting shell 2 and connected to the drill bit 3 can perform drilling operation on the liner fixed between the two support blocks 4 when it is started.

[0036] Example 2: Refer to Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 9Based on the above embodiment one, the difference is that when there are multiple drill bits 3, the mounting shell 2 has mounting cavities 21 connected to both sides. The top of the mounting shell 2 is provided with multiple circular holes 22, and the bottom of the mounting shell 2 is provided with circular holes 23 corresponding to the circular holes 22. The inner wall of the circular holes 22 is fitted with an upper mounting post 24. The surface of the upper mounting post 24 is fixedly connected with a circular block 25 that fits against the top of the mounting shell 2. The bottom of the upper mounting post 24 is fixedly connected with a square rod 26 located inside the mounting cavity 21. The bottom of the square rod 26 is fixedly connected with a lower mounting post 27 that fits against the inner wall of the circular hole 23. The drill bit 3 is fixedly connected to the bottom of the lower mounting post 27 and also includes a drive mechanism for simultaneously rotating the drill bit 3 corresponding to each square rod 26. The drive mechanism includes a drive unit 3 6 mounted on the top center of the mounting shell 2. The output end of the drive unit 3 6 is fixedly connected to a large circular gear 61 that rotates inside the mounting cavity 21. The surface of the large circular gear 61 is connected to a plurality of small circular gears 62 that are adapted to and correspond to the circular holes 1 22. The top of the small circular gears 62 is connected to the top wall of the mounting cavity 21 through a bearing. The small circular gears 62 are connected to square grooves 63 that fit against the surface of the square rods 26.

[0037] In practical use, since the mounting liner on the ball mill usually requires drilling two holes, and when a drill bit 3 is set on the mounting shell 2, one hole needs to be drilled before drilling the other, the drilling efficiency is too low and it is not suitable for drilling a batch of liners. Therefore, based on this problem, two drill bits 3 are designed on the mounting shell 2. In use, the drive unit 3 6, which uses a servo motor, drives the large circular gear 61 to rotate, so that the small circular gear 62 meshing with the large circular gear 61 can also drive the drill bit 3 on the mounting column 27 at the bottom of the square rod 26 to rotate. In this way, the pair of drill bits 3 designed at the bottom of the mounting shell 2 can drill two holes on the surface of the liner fixed between the two support blocks 4 at the same time under the drive of the drive mechanism, which is more efficient.

[0038] Example 3: Refer to Figure 6 , Figure 7 , Figure 8 and Figure 9Based on the above embodiment two, the optimization further includes an annular limiting groove 28 formed on the square rod 26. The interior of the mounting cavity 21 is provided with a pair of abutting blocks 29 that move simultaneously relative to or in opposite directions. When the two abutting blocks 29 move relative to each other, the abutting blocks 29 are separated from the inner wall of the annular limiting groove 28. When the two abutting blocks 29 move in opposite directions, the abutting blocks 29 are in contact with the interior of the annular limiting groove 28. A pair of vertical plates 210 are fixedly connected to the bottom wall of the mounting cavity 21. Each vertical plate 210 is slidably connected to a horizontal moving rod 211, one end of which is fixedly connected to the abutting block 29. On the contact block 29, an annular block 212 is fixedly connected to the surface of the horizontal moving rod 211. A first spring 213 sleeved on the horizontal moving rod 211 is fixedly connected between the annular block 212 and the vertical plate 210. A semi-circular connecting block 214 is fixedly connected to the other end of the horizontal moving rod 211. A toggle mechanism is linked between the two semi-circular connecting blocks 214. The toggle mechanism includes a drive part 215 installed on the center of the bottom wall of the mounting cavity 21. A circular rotating block 216 is fixedly connected to the surface of the output end of the drive part 215. A pair of arc-shaped toggle blocks 217 distributed in a circle are fixedly connected to the surface of the circular rotating block 216.

[0039] This technical solution is adopted because it takes into account that although the pair of drill bits 3 designed below the bottom of the mounting shell 2 can drill two holes in the liner plate simultaneously under the drive mechanism, if one of them is damaged, the other good drill bit 3 may also fail to work properly. Based on this problem, in this technical solution, an abutment block 29 is designed to be in contact with or separate from the inner wall of the annular limiting groove 28. When the abutment block 29 is in contact with the inner wall of the annular limiting groove 28, the arc-shaped actuating block 217 on the circular rotating block 216 is driven by the drive part 215 of the servo motor to abut against the abutment. When the semi-circular connecting block 214 is pressed against the surface of the arc-shaped actuating block 217, the semi-circular connecting block 214 causes the annular block 212 on the horizontal moving rod 211 to stretch the first spring 213, thereby causing the abutting block 29 connected to the other end of the horizontal moving rod 211 to tightly abut against the inner wall of the annular limiting groove 28. In this way, the integrated structure composed of the upper mounting post 24, the square rod 26, the lower mounting post 27 and the drill bit 3 can be stably limited between the top and bottom of the mounting shell 2, ensuring that the two drill bits 3 can efficiently and stably drill the liner.

[0040] When it is necessary to replace the damaged drill bit 3, simply start the drive unit 215 to drive the arc-shaped actuating block 217 on the circular rotating block 216 to continue rotating, so that the arc-shaped actuating block 217 disengages from the surface of the semi-circular connecting block 214. At this time, the horizontal moving rod 211 resets under the elastic force of the first spring 213, driving the abutment block 29 to disengage from the annular limiting groove 28. The semi-circular connecting block 214 then fits against the surface of the circular rotating block 216, so that the annular limiting groove 28, without the restriction of the abutment block 29, can slide the integrated structure consisting of the upper mounting post 24, the square rod 26, the lower mounting post 27 and the drill bit 3 along the inner wall of the first circular hole 22 and the second circular hole 23, and pull it out from the top of the mounting shell 2, realizing the rapid and efficient replacement of the drill bit 3. In this way, both single and two drill bits 3 can be replaced simultaneously.

[0041] More importantly, when the contact block 29 disengages from the inner wall of the annular limiting groove 28, the two drill bits 3 can rotate synchronously through the drive mechanism. At this time, if the drive unit 215 drives the circular rotating block 216 and the arc-shaped actuating block 217 on the circular rotating block 216 to continuously rotate along the surface of the semi-circular connecting block 214, the contact block 29 will intermittently contact the inner wall of the annular limiting groove 28, thereby generating a slight vibration force on the integrated structure composed of the upper mounting post 24, the square rod 26, the lower mounting post 27 and the drill bit 3. This vibration force helps to shake off the debris attached to the surface of the drill bit 3 after the drilling operation is completed, thereby improving the efficiency of the next batch of drilling operations.

[0042] Example 3: Refer to Figure 8 , Figure 10 and Figure 11 Based on the above embodiment two, the difference is that when the arc-shaped actuating block 217 is in contact with the semi-circular connecting block 214, the surface of the annular block 212 is attached to the air guide cylinder 218. One end of the air guide cylinder 218 is fixedly connected to one side of the vertical plate 210, and the other end of the air guide cylinder 218 is fixedly connected to a circular sealing plate 219 sleeved on the horizontal moving rod 211. An air supply pipe 220 is connected to the air guide cylinder 218, and one end of the air supply pipe 220 that passes through the outside of the mounting shell 2 is provided with a sealing plate for attaching to the top of the circular block 25. The abutting component includes a fixed shell 221 connected to one end of the air supply pipe 220. A second spring 222 is fixedly connected to the inner wall of the fixed shell 221. A movable plate 223 that fits against the inner wall of the fixed shell 221 is fixedly connected to the other end of the second spring 222. An L-shaped limiting plate 224 that extends through to the outside of the fixed shell 221 is fixedly connected to the movable plate 223. A pair of extension plates 225 are fixedly connected to the bottom of the fixed shell 221. The bottom of the extension plates 225 is fixedly connected to the top of the mounting shell 2.

[0043] When the arc-shaped actuating block 217 contacts and abuts against the surface of the semi-circular connecting block 214, it pushes the abutting block 29 connected to the other end of the horizontal moving rod 211 to fit tightly against the inner wall of the annular limiting groove 28. During this process, the annular block 212 fixed on the horizontal moving rod 211 slides along the inner wall of the air guide cylinder 218, transporting the gas inside the air guide cylinder 218 to the interior of the fixed shell 221 through the air supply pipe 220. This drives the moving plate 223 to slide along the inner wall of the fixed shell 221 until the bottom of the L-shaped limiting plate 224 fixed on the moving plate 223 fits against the top of the circular block 25. In this way, the integrated structure composed of the upper mounting column 24, the square rod 26, the lower mounting column 27, and the drill bit 3 can more stably and efficiently cooperate with the drive mechanism to perform drilling operations under the multiple limiting effects of the abutting block 29 and the L-shaped limiting plate 224. This design not only improves the drilling accuracy but also ensures the stability during the operation.

[0044] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present invention. These are all equivalent modifications and improvements made to the above embodiments based on the essential technology of the present invention, and all of these fall within the protection scope of the present invention.
