Description

Technical Field

[0001] This utility model belongs to the technical field of wear-resistant liner drilling equipment, specifically relating to a drilling device for processing wear-resistant liners. Background Technology

[0002] Wear-resistant steel plates possess high wear resistance, impact resistance, deformability, and weldability. Their processing methods are similar to ordinary steel plates, allowing for direct rolling, cutting, and drilling to create engineering components that meet the wear-resistant material requirements of industrial and mining equipment. Wear-resistant liners, as a type of wear-resistant steel plate, are widely used in metallurgy, mining, and construction. Their processing quality directly affects assembly accuracy and service life. Therefore, drilling holes in the liner during the processing of wear-resistant liners becomes a crucial step in achieving precise connection and fixation of components.

[0003] Currently, various devices exist for drilling wear-resistant liners. Among them, the "Drilling Device for Wear-Resistant Liners" (CN210231613U) utilizes a C-shaped outer shell, multiple vertically arranged supports in the recessed section, and a drive motor mounted on a lifting plate. This allows for the fixing of a drill bit at the output end, with a liner moving device located below the drill bit, thus achieving efficient and precise drilling of wear-resistant liners. This technical solution effectively solves the problems of traditional manual drilling, low drilling efficiency, and inability to guarantee hole position accuracy and precision, demonstrating high social value and application prospects.

[0004] However, existing technologies still have some shortcomings, specifically in the following aspects:

[0005] 1. Insufficient flexibility in drilling position adjustment

[0006] In existing equipment, wear-resistant liners are typically held horizontally on a liner moving device. However, this device can only move in one direction (e.g., laterally only) and cannot perform multi-directional fine adjustments in both the X and Y axes, making it inconvenient to adjust the drilling position. When the opening position of the wear-resistant liner needs to be changed, the drilling device, which is fixedly mounted on the frame, cannot adapt flexibly, which may cause deviations between the drilling position and the design requirements, affecting the machining accuracy.

[0007] 2. Insufficient clamping stability and dynamic adjustment capability.

[0008] Wear-resistant liners are prone to displacement or deformation during machining due to drilling vibrations and other factors. Traditional horizontal clamping methods and fixed liner moving mechanisms have limitations in preventing workpiece slippage and cannot provide sufficient stable support for wear-resistant liners of different sizes and shapes. In addition, existing equipment lacks automated and dynamic adjustment mechanisms, and cannot correct the drilling position in real time during machining, further limiting machining accuracy and efficiency. Utility Model Content

[0009] To address the problems existing in the prior art, the purpose of this utility model is to provide a drilling device for processing wear-resistant liners. This device can not only achieve multi-directional precise adjustment of the drilling position of the wear-resistant liner along the X and Y axes through a hydraulic drive mechanism, but also be equipped with a flexible clamping mechanism to ensure that the wear-resistant liner remains stable during the drilling process, thereby improving the drilling efficiency and accuracy and meeting the requirements of modern engineering applications for efficient and precise processing of wear-resistant liners.

[0010] To achieve the above objectives, this utility model provides the following technical solution:

A drilling motor is vertically fixed on the bottom surface of the slider, and a drill rod is vertically fixed at the bottom output end of the drilling motor.

[0012] Furthermore, a lifting motor is vertically fixed on the top surface of the frame, and the output end of the lifting motor is vertically rotatably connected to a lifting screw.

[0013] Furthermore, a threaded sleeve is vertically fixed in the middle of the orifice plate, and the threaded sleeve is threadedly connected to the lifting screw.

[0014] Furthermore, a first hydraulic rod is horizontally fixed to one end of the slide bar, and the output end of the first hydraulic rod is fixed to one end face of the slide block.
