Abstract
Disclosed is a single-bend shell angle machining and molding fixture used in angle machining of a single-bend shell of a large oblique well, which comprises a left circular tubular eccentric sleeve, a right circular tubular eccentric sleeve, a machined bent shell angle, an alignment datum line, a right eccentric sleeve screw hole, a distance between the two circular tubular eccentric sleeves, a left eccentric sleeve screw hole, and a diameter of the outer ring of a universal shaft bent shell. The fixture mainly comprises the left circular tubular eccentric sleeve and the right circular tubular eccentric sleeve. The distance between the two circular tubular eccentric sleeves is determined according to the length of a workpiece and is equal to or shorter than the length of the inner wall of a pipe cart. The centerline of the outer rings of the eccentric sleeves and the centerlines of the inner holes thereof form the machined single-bend shell angle, and the alignment datum line is arranged on the same centerline of the two eccentric sleeves. Eccentric sleeve screw holes are arranged on the tubular walls of both the left and the right eccentric sleeves. The eccentric sleeves are respectively fixed with the universal shaft shell through bolts. D is the diameter of the outer ring of the universal shaft shell. The fixture solves the problem that the angle machining method in prior art is difficult to control. The fixture is widely applicable for angle machining operation of the single-bend shell of the large oblique well.
Description
Technical field:
The utility model relates to the curved housing angle machine-shaping anchor clamps of list of the curved housing angle processing of a kind of big loxosis well list usefulness.
Background technology:
Helicoid hydraulic motor is divided into four big assemblies: by-pass valve assembly, motor assembly, universal drive shaft assembly and driving-shaft assembly.Stearable assemly is used to cooperate rock bit or diamond bit, and the different BHAs of composition such as bent sub, no magnetic drill bit, stabilizer and measuring system, is used for the drillng operation of deflecting, hold angle and the horizontal segment of big loxosis well.Single curved housing is the critical component that helicoid hydraulic motor is realized deflecting, the effect of its angle decision deflecting.The method of the curved housing of present common process is the angle that the parallels of pad certain altitude formation certain angle on chuck is adjusted processing, and this method processing is relatively more difficult, and the difficult control of angle.In order to process single curved housing exactly, improve process velocity, we have developed the curved housing angle machine-shaping anchor clamps of a kind of list.
The utility model content:
The purpose of this utility model provides the curved housing angle machine-shaping anchor clamps of a kind of list, and these anchor clamps have solved the curved housing machining angle of the list that exists in the prior art and adjusted the i.e. difficulty of machining angle, the unmanageable again problem of angle with parallels.
The technical scheme that its technical problem that solves the utility model adopts is: single curved housing angle machine-shaping anchor clamps are by tubular left side eccentric bushing, the right eccentric bushing of tubular, the curved housing angle of processing, align datum line, right avertence heart external threading hole, two tubular eccentric bushing spacings, left avertence heart external threading hole, the curved housing outside diameter of universal drive shaft is formed: these anchor clamps mainly are made of tubular left side eccentric bushing and the right eccentric bushing of tubular, two eccentric bushing spacing L determine according to Workpiece length, but L can not surpass pipe car inwall length, the α angle that eccentric bushing cylindrical center line and its inner hole centreline are constituted is the curved housing angle of work sheet, on left avertence heart casing wall, be provided with a left avertence heart external threading hole, the right avertence heart puts and is provided with a right avertence heart external threading hole, with bolt eccentric bushing is fixed with the universal drive shaft housing respectively, D is a universal drive shaft housing outside diameter.Right avertence heart cover with these anchor clamps during use is clipped on the pipe car chuck, and left eccentric bushing cylindrical is identical with cinclides in the pipe car, puts into pipe car inside, rises and supports centralizing function.In the practical application, turner is standardized fine line on universal drive shaft housing cylindrical, the pipe car is before processing, as long as two eccentric bushings are enclosed within on the universal drive shaft housing cylindrical, the datum line of end face is aimed at the fine line on the universal drive shaft housing cylindrical, the interval predetermined distance, and making the interior orifice angle of two eccentric bushings is design angle, and with bolt these anchor clamps are fixed on the universal drive shaft housing, realized the processing of single curved housing.
The beneficial effects of the utility model are, this clamp structure is simple, and convenient processing and manufacture is enhanced productivity; The processing of universal drive shaft housing bent angle accurately improves the deflecting accuracy of single bended screwdrill; The security and the good stability of single bended screwdrill.
