Different types of liners can also be used to adjust the movement of the grinding media to enhance the crushing effect of the grinding media on the materials, which helps to improve the grinding efficiency of the mill, increase output, and reduce metal consumption. During the processing of liners, holes need to be drilled to facilitate the subsequent fixing of the liners with bolts.

[0003] For example, Chinese utility model patent publication number CN210451058U discloses a drilling device for an upper liner plate. This utility model mainly addresses the technical problem of low production efficiency in the aforementioned processing methods. The technical solution adopted by this utility model is: a drilling device for an upper liner plate, comprising a drill and an upper liner plate clamp; the drill consists of a multi-axis drill and a fixing frame, the multi-axis drill being bolted to the middle of one side of the vertical plate of the fixing frame, and the drive shaft of the multi-axis drill being connected to a lathe chuck; the upper liner plate clamp consists of a liner plate support, fixing bolts, a positioning sleeve, a clamping plate, a fixing nut, a set bolt, and a stop bar; bolt holes are provided on both sides of the vertical plate of the liner plate support, the fixing bolts passing through the bolt holes in the vertical plate of the liner plate support, the positioning sleeve, and the clamping plate, and connecting to the fixing nut; the stop bar is vertically mounted on both sides of one side of the vertical plate of the liner plate support and located inside the positioning sleeve; the set bolts are evenly distributed in the threaded holes of the clamping plate.

[0004] However, in actual use, the aforementioned existing devices generate a large amount of debris during the drilling process, which makes it difficult to clean the debris in the gaps on the surface of the workbench and thus hinders the rapid collection of debris. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a drilling device for liner bolt holes that improves the efficiency of cleaning debris generated during drilling, avoids debris from being trapped in gaps and making cleaning difficult, and improves practicality.

[0006] This utility model discloses a drilling device for lining bolt holes, comprising a drilling platform, a support rod fixedly installed at the top of the drilling platform, a semi-circular support plate fixedly installed at the top of the support rod, a support plate fixedly installed at the top area of ​​the support rod, two support mechanisms symmetrically arranged at the top of the support plate, and a drilling mechanism installed at the top area of ​​the drilling platform; the support mechanism includes a top plate, a groove is formed on the outer side wall of the top plate, the groove on the top plate is rotatably connected to the outer side wall of the semi-circular support plate, a fixed shaft is fixedly installed on the outer side wall of the semi-circular support plate, the outer side wall of each top plate is rotatably connected to the outer side wall of the fixed shaft through two rotating plates, the fixed shaft is installed at the center position of the semi-circular support plate, and a fixing mechanism is provided at the top of each top plate;

[0007] The fixing mechanism includes a locking block, a through hole on the top plate, the through hole on the top plate being slidably connected to the locking block, a first limiting plate being fixedly installed on the outer side wall of the locking block, the first limiting plate being tightly fitted to the top of the top plate, a first screw being horizontally screwed onto the locking block, a clamping plate being rotatably installed at one end of the first screw, and the bottom end of the clamping plate being slidably fitted to the top of the top plate.

[0008] Two anti-splash mechanisms are symmetrically arranged on the outer wall of the clamping plate. The bolt hole drilling device for the liner plate provides initial support for the liner plate through the top of the top plate. By rotating the first screw, the clamping plate is simultaneously driven to slide on the top of the top plate, thereby clamping and fixing the liner plate at the top of the top plate. The drilling mechanism drills holes in the fixed liner plate. After drilling is completed, the top plate rotates on the outer wall of the semi-circular support plate, thereby tilting the top plate and disengaging the locking block along with the first screw, clamping plate, and first limiting plate from the top plate. This allows the drilling debris to be quickly collected, improving the efficiency of the device in cleaning drilling debris, preventing debris from being trapped in gaps and making cleaning difficult, and improving practicality.

[0009] Preferably, the anti-splash mechanism includes a slide plate, which is slidably connected to the outer wall of the clamping plate. A baffle is fixedly installed on the outer wall of the slide plate. The bottom ends of the slide plate and the baffle are slidably connected to the top end of the top plate. The slide plate slides on the clamping plate, thereby synchronously moving the baffle to the side of the liner plate that needs to be drilled, and the baffle isolates the debris generated during drilling.

[0010] Preferably, the top of the pallet has two symmetrical grooves, and a support seat is slidably installed on each groove. The top of each support seat is tightly fitted to the bottom of the two top plates. By installing the support seats, it is convenient to support the bottom of the top plates.

[0011] Preferably, the drilling mechanism includes a connecting plate, with a moving mechanism at both ends of the connecting plate, and a drilling motor fixedly installed at the top of the connecting plate. The output end of the drilling motor is located on the upper side of the top plate. By installing the connecting plate and the drilling motor, it is convenient to perform drilling operations on the liner plate.

[0012] Preferably, the moving mechanism includes two pillars, which are symmetrically fixedly installed on the top of the drilling platform. A protective plate is fixedly installed on the top of each pillar, and a base plate is slidably installed between the two pillars. Moving plates are fixedly installed on both ends of the connecting plate. A second screw is screwed onto the moving plate, with its bottom and top ends rotatably connected to the base plate and protective plate, respectively. A first motor is fixedly installed on the top of the protective plate, and its output end is fixedly connected to the top of the second screw. A limit post is provided on the top of the base plate at the other end, and the limit post is slidably connected to the connecting plate. The first motor outputs power to the second screw, thereby synchronously driving the second screw to perform longitudinal movement. Simultaneously, the movement of the second screw drives the connecting plate and the drilling motor to move. The bottom end of the drilling motor contacts the liner plate, thereby drilling the liner plate.

[0013] Preferably, two brackets are symmetrically and rotatably installed on the outer side wall of the support rod. The outer side walls of the two brackets are fixedly connected by a scraper. A collection trough is fixedly installed at the top of the drilling platform. The collection trough is rotatably connected to the support rod, and the scraper is rotatably connected to the inner side wall of the collection trough. The debris is collected through the collection trough. While rotating the scraper, the debris collected through the collection trough is guided and gathered.

[0014] Preferably, two third limiting plates are fixedly installed on the outer side wall of each of the top plates, and each third limiting plate is respectively attached to each corresponding baffle. By installing the third limiting plates, it is convenient to effectively limit the sliding baffle.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: The liner bolt hole drilling device provides initial support for the liner through the top of the top plate. Simultaneously, by rotating the first screw, the clamping plate slides on the top of the top plate, thereby clamping and fixing the liner at the top of the top plate. The drilling mechanism then drills holes in the fixed liner. After drilling, the top plate rotates on the outer wall of the semi-circular support plate, causing the top plate to tilt. This disengages the clamping block, along with the first screw, clamping plate, and first limiting plate, from the top plate, allowing the drilling debris to be quickly collected. This improves the efficiency of cleaning the drilling debris, prevents debris from remaining in gaps and hindering cleaning, and enhances practicality. Attached Figure Description
