Description

Technical Field

[0001] The utility model relates to the technical field of coal mine equipment, in particular to a drilling tool for positioning a cylinder body of a drill rod clamp. Background Art

[0002] The drill rod clamp for underground drilling rigs in coal mines is the main actuator of the full hydraulic drilling rig. It is located at the front end of the drilling rig. It can clamp and fix the drill rod during the drilling process, complete the removal or installation of the drill rod, and effectively prevent the drill rod or drilling tools from slipping. Generally, the clamps equipped with full hydraulic drilling rigs are horizontal clamps. Two hydraulic cylinders are used at both ends. There are end cover seals on the end side. The center opening of the clamp cylinder body is connected to the slip. The hydraulic cylinder drives the slip to complete the clamping of the drill rod. In the production and processing of the clamp, the processing of the clamp cylinder body occupies the main workload. First, the main shape structure of the clamp cylinder body needs to be turned, and then drilling operations such as drilling oil channels and screw holes are performed on the clamp cylinder body. At present, there are still the following problems in the production practice of the clamp cylinder body: a circle of screw holes needs to be processed on the circumference of the end side of the clamp cylinder body for assembling the end cover. When drilling screw holes, the clamp cylinder needs to be fixed vertically on the drilling machine base. However, due to the cylindrical shape of the clamp cylinder, conventional fixings cannot effectively fix it. The existing old method is to use a soft rope to tie the clamp cylinder to the drilling machine base, which is not only inconvenient for processing, but also has low production efficiency.
