Heart hole, is sleeved on final drive shaft, realizes spindle drive part around outside basic support section by rotating rotating eccentricity inner sleeve
Central rotation, reach cutting tip guiding inner sleeve cylinder inner diameter to extend and retract, realized main shaft by lock pin
Running part is fixed on a certain angle, for fixing the depth of screw cutting with guiding inner sleeve；Guiding inner sleeve, movable motor, biography
Moving gear pair, guide thread set composition axial-movement devices, movable motor drives transmission driving tooth rotation, driving tooth and driven tooth
The rotation of driven tooth is realized in occlusion, and guiding inner sleeve forms axial-movement devices with driven tooth and guide thread set and realizes guiding inner sleeve
Axially-movable and rotary motion, guiding inner sleeve drives final drive shaft part to achieve the spiral fixation locus fortune of cutting tip
Dynamic.
Described guiding inner sleeve and guide thread set are all trapezoidal threads.
Described cutting tip is diamond sintering blade.
Compared with prior art, the invention has the beneficial effects as follows:
Present invention research produces a kind of specialty equipment, the referred to as interior spiral shell milling machine of internal thread grinding machine, and its applies accordingly
Work technique, it mainly solves the problems, such as safe and reliable on coagulation great soil group, building stones, porcelain material class material being screwed.
Big pitch trapezoidal thread metal spiral shell core as rear anchor piece be arranged on concrete, building stones, in porcelain material matrix, connector
Bolt and metal spiral shell core threaded effectively power be delivered to concrete, building stones, on porcelain material matrix, by fixation body jail
It is fixed on matrix, thus reaching anchorage effect firmly.
According to different needs, process aperture, hole depth difference, spiral shell core is of different sizes, and spiral shell in-core standard thread specification is different, spiral shell
Core material is different it is not necessary to the occasion of dismounting can fill dead with grouting material is disposable after installing.
Experiments verify that the tensile strength in concrete and stability are significantly larger than expansion bolt and the change of same size
Learn crab-bolt.This method is quick, simple, use after installing, safe and reliable, dismounting and change is convenient, and bearing capacity is strong, service life
Long.Great advantage is not produce any anchorage stress on matrix, and the matrix that will not be produced by installing anchoring piece destroys.It is suitable for
In concrete structure design theory connect and on the basis of newly plant, mend plant equipment anchor bolt, setting hanging on concrete ceiling, support,
Stone material, porcelain material are connected, embedded with metal part.It is also applied for the company of other nonmetallic materials (refractory brick, glass, plastics etc.)
Connect anchoring.
