3. High technical requirements for large-diameter drilling
[0003] In view of the poor reliability, easy consumption and high manufacturing cost of ring drills in the international market, the company has developed a ring heavy drill, which is different from the ring drills on the market. During the production process, due to the need for ring heavy There are grooves drilled on the drill, which can be used to assemble steel balls in the grooves. Through this special design of balls, friction can be effectively reduced. However, in the process of drilling and positioning, due to its heavy mass, it requires It is more cumbersome, time-consuming and labor-intensive to carry out circular drilling operation on it and only use manual rotation positioning

Abstract

The invention provides a positioning clamp for annular heavy drill machining, and belongs to the technical field of annular heavy drill machining equipment. The positioning clamp for annular heavy drill machining comprises an upper platform, a lower platform, a supporting assembly and a rotating assembly, wherein the supporting assembly is arranged on the upper platform; the rotating assembly is arranged on the lower platform; two concentric annular chutes are formed in the upper platform; the supporting assembly comprises a plurality of clamping pieces which slide in the annular chutes and atleast two pressing and fixing pieces arranged on the upper platform; each clamping piece comprises a sliding block group, a vertical plate group, a supporting plate and a clamping bolt group; the rotating assembly comprises connecting rods fixed on the bottoms of sliding blocks, a rotating table connected to ends of the connecting rods and a driving piece which drives the rotating table to rotate; an annular channel which allows the corresponding connecting rod to penetrate through is formed in the top of each annular chute; each pressing and fixing piece comprises a pressing and fixing boltgroup, a supporting block group and a rotating rod; and two ends of each rotating rod are connected to two supporting blocks of the corresponding supporting block group through bearings. The positioning clamp for annular heavy drill machining is simple in structure and convenient to position, and automatic rotary perforation can be realized.

Description

technical field [0001] The invention belongs to the technical field of ring heavy drilling processing equipment, and in particular relates to a positioning fixture for ring heavy drilling processing. Background technique [0002] Years of practice have proved that there are three major characteristics in the field of high-precision drilling: 1. It is difficult to drill under complex geological conditions; 2. It is easy to damage the ecological environment during drilling and development. 3. Large-diameter drilling requires high technology. As the two core components of the drilling rig, the guide sleeve and the annular re-drilling are very critical in the construction of a high-performance drilling rig. [0003] In view of the poor reliability, easy consumption and high manufacturing cost of ring drills in the international market, the company has developed a ring heavy drill, which is different from the ring drills on the market. During the production process, due to the n...
