Abstract
Description
Technical Field
[0001] This application relates to the field of wear-resistant liner processing, and more specifically, to a drilling device for wear-resistant liners. Background Technology
[0002] Wear-resistant liners refer to various wear-resistant steel plates processed through cutting, rolling deformation, drilling, and welding. They possess high wear resistance, impact resistance, deformability, and weldability. During processing, wear-resistant liners require drilling. When drilling, the drill bit needs to be aligned with the drilling position. However, current wear-resistant liner drilling equipment often lacks a proper drilling positioning structure. Workers typically rely on experience and visual observation to determine if the drill bit is aligned with the hole. This reliance on experience and visual observation is prone to errors, easily causing hole misalignment and leading to the scrapping of the wear-resistant liner, resulting in a high failure rate. Utility Model Content
[0003] To overcome the above shortcomings, this application provides a drilling device for wear-resistant liners, which aims to improve the problems of easy hole displacement, easy scrapping of wear-resistant liners, and high drilling failure rate.
[0004] This application provides a drilling device for wear-resistant liners, including a base and a positioning component.
[0005] The upper surface of the base is provided with a movable lifting component, the movable end of the movable lifting component is provided with a connecting plate, the plate body of the connecting plate is provided with a motor, and the rotating end of the motor is provided with a drill bit.
[0006] The positioning assembly includes a slide rod, a positioning ring, a limiting ring, and a laser indicator. The slide rod slides through the body of the connecting plate, and a limiting plate is provided at the top of the slide rod. The positioning ring is connected to the bottom of the slide rod, and the limiting ring is slidably placed above the positioning ring. The laser indicator is connected to the limiting ring and slides through the interior of the positioning ring. The drill bit, the positioning ring, the limiting ring, and the laser indicator are coaxially arranged.
[0007] In one specific implementation, the movable lifting component includes a first electric slide, a second electric slide, and a third electric slide. The first electric slide is fixedly connected to the upper surface of the base, the bottom end of the second electric slide is fixedly connected to the moving end of the first electric slide, and one end of the third electric slide is fixedly connected to the moving end of the second electric slide.
[0008] In one specific implementation, the moving end of the third electric slide is provided with the connecting plate, and the motor is fixedly connected to the upper surface of the connecting plate.
[0009] In one specific implementation, the rotating end of the motor rotatably penetrates through the plate of the connecting plate, and the rotating end of the motor is provided with a connecting seat, and the drill bit is connected to the connecting seat.
[0010] In one specific implementation, the upper surface of the base is provided with a clamp, and there are two sets of clamps, with the two sets of clamps being arranged correspondingly.
[0011] In one specific implementation, both sets of clamps include a fixed clamping plate, an L-shaped fixed plate, a threaded rod, and a movable clamping plate. The two fixed clamping plates are fixedly connected to the upper surface of the base, and the two fixed clamping plates are correspondingly arranged. The bottom ends of the two L-shaped fixed plates are fixedly connected to the upper surface of the base, and the L-shaped fixed plate is located on one side of the fixed clamping plate. The threaded rod is threaded through the top wall of the L-shaped fixed plate. The movable clamping plate is rotatably connected to the bottom end of the threaded rod, and the movable clamping plate slides against one side of the L-shaped fixed plate.

[0014] In one specific implementation, each of the slide rods is provided with a connecting block at its bottom end, and both connecting blocks are fixedly connected to the outer ring wall of the positioning ring, with the two connecting blocks arranged symmetrically.
[0015] In one specific implementation, the drill bit is located directly above the positioning ring, and the drill bit is configured correspondingly to the positioning ring.
[0016] The beneficial effects of this utility model are as follows: The wear-resistant liner drilling device obtained by the above design allows for the movement of the drill bit and laser indicator by a movable lifting component. The laser indicator emits a laser beam that illuminates the liner to be drilled, thus accurately determining whether the drill bit is aligned with the desired drilling position. Once the drill bit is aligned, the limiting ring and laser indicator are moved upwards, allowing the laser indicator to be removed from the positioning ring, thus completing the disassembly of the laser indicator and the limiting ring. Then, the movable lifting component moves the connecting plate downwards, and the drill bit is rotated by a motor. The positioning ring first contacts the liner, and the drill bit passes through the positioning ring to drill a hole in the liner. The laser indicator is coaxially arranged with the drill bit, and the laser beam emitted by the laser indicator accurately determines whether the drill bit is aligned with the desired drilling position, thus reducing drilling errors and hole misalignment, preventing the wear-resistant liner from being scrapped, and lowering the drilling defect rate.

[0025] Please see Figure 1 This application provides a drilling device for wear-resistant liners, including a base 100 and a positioning component 200.
[0026] Please see Figure 1-3 The upper surface of the base 100 is provided with a movable lifting component 110, which includes a first electric slide 111, a second electric slide 112, and a third electric slide 113.

[0028] In this embodiment, a motor 130 is provided on the plate body of the connecting plate 120. The motor 130 is fixedly connected to the upper surface of the connecting plate 120.

The drill bit 140 is connected to the connecting seat 131.
[0029] Please see Figure 1 and 2The upper surface of the base 100 is provided with a clamp 150. There are two sets of clamps 150, which are arranged correspondingly. Each set of clamps 150 includes a fixed clamping plate 151, an L-shaped fixed plate 152, a threaded rod 153, and a movable clamping plate 154. The two fixed clamping plates 151 are fixedly connected to the upper surface of the base 100. The bottom ends of the two L-shaped fixed plates 152 are fixedly connected to the upper surface of the base 100. The L-shaped fixed plate 152 is located on one side of the fixed clamping plate 151. The threaded rod 153 is threaded through the top wall of the L-shaped fixed plate 152. The top ends of the two threaded rods 153 are provided with a rotating hand plate 1531.
[0030] In this embodiment, the movable clamping plate 154 is rotatably connected to the bottom end of the threaded rod 153, the movable clamping plate 154 is slidably attached to one side of the L-shaped fixed plate 152, the movable clamping plate 154 is correspondingly arranged with the fixed clamping plate 151, and the movable clamping plate 154 is located above the fixed clamping plate 151.
[0031] Please see Figure 1-4 The positioning component 200 includes a slide rod 210, a positioning ring 220, a limiting ring 230, and a laser indicator 240. The slide rod 210 slides through the plate body of the connecting plate 120. A limiting plate 211 is provided at the top of the slide rod 210. There are two slide rods 210, and both slide rods 210 slide through the plate body of the connecting plate 120. The two slide rods 210 are symmetrically arranged, and a limiting plate 211 is provided at the top of each of the two slide rods 210. The lower surface of the limiting plate 211 is in contact with the connecting plate 120.
[0032] In this application, the positioning ring 220 is connected to the bottom end of the slide rod 210, and the bottom end of the slide rod 210 is provided with a connecting block 212. Both connecting blocks 212 are fixedly connected to the outer ring wall of the positioning ring 220, and the two connecting blocks 212 are symmetrically arranged.
[0033] In this embodiment, the limiting ring 230 is slidably placed above the positioning ring 220, the laser indicator 240 is connected to the limiting ring 230, and the laser indicator 240 slides through the interior of the positioning ring 220. The drill bit 140, the positioning ring 220, the limiting ring 230 and the laser indicator 240 are coaxially arranged.
[0034] In a specific configuration, the drill bit 140 is positioned directly above the positioning ring 220, and the drill bit 140 is positioned corresponding to the positioning ring 220. The drill bit 140 can penetrate the interior of the positioning ring 220.
[0035] Specifically, the working principle of the wear-resistant liner drilling device is as follows: During use, the liner to be drilled can be placed between two fixed clamping plates 151 and a movable clamping plate 154. Then, the two threaded rods 153 are rotated, causing the movable clamping plate 154 to move downwards. The liner is then clamped and fixed by the fixed clamping plates 151 and 154. The first electric slide 111 can move the connecting plate 120 left and right, and the third electric slide 113 can move the connecting plate 120 back and forth, thereby moving the drill bit 140 and the laser indicator 240. The laser indicator 240 emits a laser beam that illuminates the liner to be drilled, thus accurately determining whether the drill bit 140 is aligned with the desired drilling position. Once the drill bit 140 is aligned, the limiting ring 230 and the laser indicator 240 are moved upwards, allowing the laser indicator 240 to be moved from inside the positioning ring 220. After removal, the laser indicator 240 and the limiting ring 230 can be disassembled. Then, the second electric slide 112 can drive the connecting plate 120 to move downwards. Then, the motor 130 is turned on to drive the drill bit 140 to rotate. The downward movement of the connecting plate 120 will drive the drill bit 140 and the positioning ring 220 to move downwards. The positioning ring 220 will first contact the liner plate, and the drill bit 140 will pass through the positioning ring 220 to drill a hole in the liner plate. During the drilling process, the positioning ring 220 will block the flying drill debris to prevent it from flying around. The laser indicator 240 is coaxially set with the drill bit 140. The laser emitted by the laser indicator 240 can accurately determine whether the drill bit 140 is aligned with the position to be drilled. The laser indicator 240 can be disassembled during drilling, which makes the drilling less prone to errors and the hole less prone to displacement, so that the wear-resistant liner plate is less likely to be scrapped, and the drilling defect rate can be reduced.
