[0002] The ball mill liner is used to protect the cylinder from direct impact and friction between the grinding body and the material. At the same time, different forms of liners can be used to adjust the movement state of the grinding body to enhance the grinding effect of the grinding body on the material, which helps to improve the grinding efficiency of the mill, increase output and reduce metal consumption.

[0003] The shapes of ball mill liners are different. Long strip liners, smooth liners and stepped liners are common.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Reference Figure 1-Figure 9 As shown, the present invention provides a drilling device for ball mill liner production, comprising a workbench 1, and also comprising:

[0037] A U-shaped plate 3 is fixedly connected to the top of the workbench 1, and a movable groove is provided on the top of the U-shaped plate 3 for installing a part of the structure of the hole opening mechanism 4;

[0038] The hole-opening mechanism 4 is arranged in the movable groove formed on the U-shaped plate 3 and is used for opening holes in the production of the ball mill liner. The hole-opening mechanism 4 includes a mounting plate 41 which is arranged inside the movable groove and can slide in the movable groove. A cylinder 43 which can be extended downward is arranged on the mounting plate 41. A connecting plate 42 is fixedly connected to the telescopic end of the cylinder 43. A replaceable hole-opening head is fixedly connected to the bottom of the connecting plate 42.

[0039] The positioning mechanism 2 is arranged in the middle position of the top of the workbench 1, and is used for fixing and clamping the ball mill liner before drilling a hole. The positioning mechanism 2 includes a placement seat 26 arranged in the middle of the workbench 1, and L-shaped plates 22 for limiting the left and right positions of the workpiece are arranged on the left and right sides of the placement seat 26. A limiting piece for limiting the upper and lower positions of the workpiece is arranged on the top of the L-shaped plate 22. A debris cleaning component 21 is arranged on the rear side of the workbench 1, which is used for cleaning debris of the positioning mechanism 2 when drilling a hole in the ball mill liner.

[0040] In a further embodiment, referring to Figure 4-Figure 6 The left and right sides of the placement seat 26 are provided with mounting holes 262, and the inner side of the mounting hole 262 is fixedly connected with an electric telescopic rod 25, and the telescopic end of the electric telescopic rod 25 is fixedly connected with the outer side of the corresponding L-shaped plate 22. The opposite surfaces of the two L-shaped plates 22 are fixedly connected with rectangular rods 221. A rectangular hole 263 is opened on the outer side of the placement seat 26, and the rectangular rod 221 extends into the corresponding rectangular hole 263 and is slidably connected with the inner wall of the rectangular hole 263.

[0041] Specifically, the rectangular hole 263 and the rectangular rod 221 are provided to limit the moving track of the L-shaped plate 22, ensuring that the L-shaped plate 22 will not deflect due to the force generated when drilling the ball mill liner during use.

[0042] In this embodiment, the contraction of the electric telescopic rods 25 on both sides drives the L-shaped plates 22 on both sides to move toward the middle, fixing and clamping the ball mill liner placed on the top of the placement seat 26 to ensure that it will not move in the left and right directions during drilling.

[0043] In a further embodiment, referring to Figure 4 and Figure 6 The limiting member includes two symmetrically distributed support blocks 24, the two support blocks 24 are fixedly connected to the top of the L-shaped plate 22, and mounting rollers 243 are arranged on the opposite surfaces of the two support blocks 24. The outer sides of the mounting rollers 243 are fixedly connected with convex strips 242 of varying sizes in sequence, and a servo motor 241 is fixedly connected to the outer side of one of the support blocks 24. The servo motor 241 is fixedly connected to a transmission rod 244 through an output shaft, and the other end of the transmission rod 244 passes through one of the support blocks 24 and is movably connected to the outer side of the other support block 24 through a bearing, and the mounting roller 243 is fixedly connected to the outer side of the transmission rod 244.

[0044] Specifically, the support block 24 is used to support structures such as the drive motor 23 and the mounting roller 243. The outer side of the convex strip 242 is set to be arc-shaped. When the outer side is in close contact with the top of the ball mill liner, the ball mill liner is limited.

[0045] In this embodiment, the servo motor 241 drives the transmission rod 244 to rotate through the output shaft, and the rotation of the transmission rod 244 drives the installation roller 243 to rotate. Under the action of the convex strip 242 on the outside of the installation roller 243, the ball mill liner of different thicknesses on the placement seat 26 can be pressed down and fixed, further improving the stability of the ball mill liner during drilling.

[0046] In a further embodiment, referring to Figure 4 and Figure 7-Figure 8 The debris cleaning component 21 includes a fixing rod 213, which is fixedly connected to the rear side of the workbench 1, and the other end of the fixing rod 213 is fixedly connected to a lower opening box 211, and a negative pressure fan 214 is arranged on the rear side of the lower opening box 211. A connecting groove 216 is provided on the front side of the lower opening box 211, and a rubber ring 215 is provided on the outer side of the connecting groove 216. A sealing cover 212 is provided on the bottom of the lower opening box 211, and reserved grooves 264 distributed at equal intervals are provided on the top of the placement seat 26. A through groove 261 is provided on the front side of the placement seat 26, and the bottom of the reserved groove 264 is connected to the inside of the through groove 261. An oblique opening box 421 is fixedly connected to the front side of the connecting plate 42, and a micro fan 4211 is arranged on the top of the oblique opening box 421.

[0047] Specifically, the negative pressure fan 214 is arranged outside the lower opening box 211, and the connection between the negative pressure fan 214 and the lower opening box 211 is arranged in a filter mesh shape, which is convenient for blocking the inhaled debris and entering the sealing cover 212 at the bottom of the lower opening box 211, so as to facilitate subsequent cleaning;

[0048] The air blowing of the micro fan 4211 can generate a blowing force on the outer inclined surface of the bottom of the inclined opening box 421 to blow away the debris remaining on the top of the placement seat 26 to prevent it from affecting the processing accuracy of the ball mill liner.

[0049] In this embodiment, when the drilling position of the ball mill liner is changed, the placement seat 26 drives the ball mill liner to move backward. When the last hole is drilled, the rear side of the placement seat 26 contacts the front side of the lower opening box 211, and the rear side of the through groove 261 fits with the front side of the connecting groove 216. The negative pressure fan 214 can extract the air in the through groove 261. The flow of air drives the debris generated during drilling to move backward and enter the lower opening box 211. The sealing cover 212 is removed regularly for cleaning.

[0050] In a further embodiment, referring to Figure 1-Figure 5A mounting groove 231 is provided at the bottom of the workbench 1, and an internal thread block 233 is provided inside the mounting groove 231. The internal thread block 233 is fixedly connected to the bottom of the placement seat 26. A driving motor 23 is fixedly connected to the rear side of the workbench 1. The driving motor 23 is fixedly connected to a screw rod 232 through an output shaft. The front end of the screw rod 232 passes through the rear side of the mounting groove 231 and is movably connected to the front side of the mounting groove 231 through a bearing. The internal thread block 233 is threadedly connected to the outside of the screw rod 232, and a slider 234 is fixedly connected to the outside of the internal thread block 233.

[0051] Specifically, a sliding groove is provided inside the installation groove 231 , and the sliding block 234 is slidably connected inside the sliding groove to limit the moving track of the internal thread block 233 .

[0052] In this embodiment, the driving motor 23 can drive the screw rod 232 to rotate through the output shaft. The rotation of the screw rod 232 drives the internal thread block 233 to move, thereby driving the placement seat 26 fixed on the top of the internal thread block 233 to move, and adjusting the position of the fixed ball mill liner to facilitate drilling at different positions.

[0053] In a further embodiment, referring to Figure 1-Figure 2 and Fig. 9 A threaded rod 411 is threadedly connected to the inner side of the movable groove, and the left end of the threaded rod 411 passes through the movable groove and extends to the outside of the U-shaped plate 3. A limiting rod 412 is fixedly connected to the inner side of the movable groove, and the mounting plate 41 is slidably connected to the outside of the limiting rod 412.

[0054] In this embodiment, rotating the threaded rod 411 can drive the mounting plate 41 to move, thereby adjusting the position of the punching head 44 in the left and right directions. By adjusting the position of the punching head 44, holes can be drilled at different positions of the fixed ball mill liner.

[0055] The working principle of the present invention is as follows:

[0056] The ball mill liner to be drilled is placed on the top of the placement seat 26, and the electric telescopic rod 25 is started. The contraction of the electric telescopic rod 25 drives the two L-shaped plates 22 to move toward the middle until the two L-shaped plates 22 limit the ball mill liner from both sides, and then the ball mill liner is initially clamped;

[0057] The two servo motors 241 are started at the same time. The servo motors 241 drive the transmission rod 244 to rotate through the output shaft. The transmission rod 244 drives the installation roller 243 to rotate. The installation roller 243 rotates and the convex strips 242 fixed on the outside thereof rotate along with it until one of the convex strips 242 stops when it can be limited from the top of the ball mill liner. At this time, the ball mill liner is fixed.

[0058] According to the drilling requirements of the ball mill liner, the threaded rod 411 is rotated. The rotation of the threaded rod 411 drives the position of the mounting plate 41 to move. The position movement of the mounting plate 41 drives the position movement of the punching head 44 through the cylinder 43 and the connecting plate 42, thereby adjusting the drilling position of the ball mill liner.

[0059] When drilling holes in the ball mill liner, the holes are drilled from the back side of the ball mill liner to the front. When the hole on the front side of the ball mill liner is drilled, the back side of the placement seat 26 contacts the front side of the lower opening box 211, and the negative pressure fan 214 drives the air in the lower opening box 211 to flow outward, so that the lower opening box 211 is in a negative pressure state, generating suction, sucking in the debris remaining in the through groove 261 and the reserved holes connected to it, thereby cleaning the debris inside the placement seat 26, and the micro fan 4211 cleans the debris remaining on the top of the placement seat 26 through the inclined opening box 421 to complete the drilling of the ball mill liner.

[0060] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
