Manufacturing method of improved drill tail front guide sleeve
The technical problem to be solved by the utility model is to provide an improved drill tail guide sleeve, which improves the existing drill tail guide sleeve, increases the amount of lubrication by adding lubricating oil holes, and reduces the hard impact of components by replacing materials. The utility model effectively solves the problem that the drill pipe is easy to break during the use of the hydraulic rock drill, and has the characteristics of increasing the amount of lubrication, preventing the drill pipe from breaking, reducing the cost of production operation and eliminating the hidden danger of safety.

Background technology:
The main equipment of underground mechanized mining of phosphate rock is the rock drilling rig, and the hydraulic rock drill is one of the main accessories of the rock drilling rig. At present, the drill tail guide sleeve of the hydraulic rock drill is made of steel or copper, including the hollow cylindrical structure of the drill pipe cavity, the first oil guide rail and the first lubricating oil hole. The guide sleeve is matched with the hydraulic rock drill. The first oil guide rail is a groove provided on the side of the front guide sleeve of the annular drill tail. The first lubricating oil hole is located at the 1/3 of the side of the drill tail guide sleeve and is arranged in the first guide rail. In actual operation, the lubrication is insufficient, and the metal guide sleeve at the tail of the drill pipe and the tail of the drill pipe have impact wear. Long-term operation makes the tail of the drill pipe wear thin and cannot withstand the impact of fracture.

A front guide sleeve based on an improved drill tail, comprising a hollow cylindrical structure composed of a drill rod cavity, a first oil guide rail and a first hole requiring lubricating oil. The front guide sleeve of the drill tail is matched with a hydraulic rock drill. The drill rod cavity is provided with a round hole centered on the bottom surface of the front guide sleeve of the drill tail and penetrates through the upper and lower bottom surfaces of China, located at one third of the technologies from the lower bottom surface; The first selected lubricating oil hole is a round hole penetrating through the side surface of the front guide sleeve of the drill tail. The company where the lubricating oil hole is located passes through the axis of the front guide sleeve of the drill tail in a straight line and is arranged in the first oil guide rail to cooperate with each other. Its improvement work is mainly characterized by: it includes the second oil guide rail and the second lubricating oil hole added by the enterprise. The device makes some improvements to the existing drill tail front guide sleeve, through increasing and lubricating oil holes to increase the amount of lubrication, replacement of different materials can reduce the hard impact of system components, with a significant increase in lubrication, prevent drill rod fracture, reduce product production management operation time cost, eliminate the characteristics of network security risks.
an improveddrill tailRail sleeve, a hollow cylindrical structure, including a drill pipe cavity, a first guide rail and a first lubricating oil hole, the improvement feature is: including an additional second oil guide rail and a second lubricating oil hole; the second guide rail is a sleeve The groove on the side surface is located at the 2/3 of the lower bottom surface; the second lubricating oil hole is a round hole penetrating the side surface of the front guide sleeve, and the line passes through the drill sleeve shaft and is arranged on the second oil guide rail; the device improves the existing drill tail guide sleeve, increases the lubrication amount by increasing the lubricating oil hole, replaces the material, reduces the hard impact of the components, effectively solves the problem of hydraulic drilling rig operation, increases the lubrication amount, prevents the drill pipe from breaking, and reduces the production and operation cost, Eliminate potential safety risk characteristics.
