Abstract
The utility model discloses a multifunctional core shaft device. The multifunctional core shaft device comprises a positioning component and a compressing component, wherein the positioning component comprises a core shaft and a flat key, the core shaft is a step shaft, a key groove is machined in the right section of the core shaft, the flat key is arranged in the key groove, the core shaft is connected with an eccentric bushing, eccentric holes are respectively machined in the left end surface and the right end surface of the core shaft, and the compressing component is connected with the core shaft. The multifunctional core shaft device can be applied to machining process of the eccentric bushing, such as turning, milling and grinding, enables the positioning to be simple and operation to be convenient when the eccentric bushing is machined, and the machining quality of machining is guaranteed.
Description
Technical field
The utility model belongs to the mach servicing unit of mechanical field.
Background technology
In machining process, particularly in accurate machined, whether particularly important for crudy the accurate positioning of workpiece is.In the process that eccentric bushing is processed, generally utilize dial gauge to carry out centering during turning, during milling, positioning spline is generally by the line centering.Such processing mode location difficulty, centering time are long, and product quality be difficult for to guarantee, cause with the offset error of a collection of eccentric bushing greatly, and the positioning spline on eccentric bushing is large with respect to the error of maximum eccentricity amount position.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of positioner, it can be applied to eccentric bushing car, mill, the process such as mill.When this device makes the processing eccentric bushing, the location is simple, easy to operate, and can guarantee the quality of processing.
This novel a kind of Multifunctional core shaft device, it is characterized in that: it comprises positioning element, compacting part; Positioning element comprises mandrel, flat key, and mandrel is multidiameter, is processed with keyway on its right section, and flat key is placed in keyway, and mandrel is connected with eccentric bushing, all is processed with eccentric orfice on the left and right end face of mandrel; Compacting part is connected with mandrel.
Compacting part comprises gland, screw; Be processed with screwed hole on the right side of mandrel, gland is connected with mandrel by screw.
When the cylindrical to eccentric bushing carries out finish turning, (first with the endoporus of eccentric bushing and both ends of the surface car to requiring, upper slotting machine is inserted out inner hole key slot), eccentric bushing is contained in outside mandrel, compress with gland, the mandrel left end is held in scroll chuck, and left end peaks at eccentric orfice with thimble, right-hand member peaks at eccentric orfice with the tailstock thimble, and then the finish turning excircle of workpiece stays grinding allowance.
When eccentric bushing was carried out grinding, similar with the turning clamping method, just workpiece rotating was by the rotation of heart carrier for bolt clamping mandrel left end band moving mandrel, and the grinding work piece cylindrical is to requiring.
When eccentric bushing is carried out milling, similar with the turning clamping method, determine the position of first locating slot by ruling, the mandrel left end is held in the dividing head scroll chuck, the front and back thimble peaks in eccentric orfice, first groove has milled rear with second groove of dividing head calibration milling, other groove of milling by that analogy.
Adopt the utility model Multifunctional core shaft device, in the eccentric bushing process, it is easy to be accurate to locate, and has both guaranteed crudy, has saved again the clamping centering time, has improved operating efficiency.
Description of drawings
Fig. 1 is the structural representation of a kind of Multifunctional core shaft device of the utility model and eccentric bushing assembling;
Fig. 2 is the right view of Fig. 1;
Fig. 3 is the cutaway view along A-A line in Fig. 1.
In figure: 1, mandrel, 2, gland, 3, screw, 4, flat strong, 5, eccentric centre bore, 6, eccentric bushing.
The specific embodiment
From Fig. 1, Fig. 2, Fig. 3 as can be known, this novel a kind of Multifunctional core shaft device, it comprises positioning element, compacting part; Positioning element comprises mandrel 1, flat key 4, and mandrel 1 is multidiameter, is processed with keyway on its right section, and flat key 4 is placed in keyway, and mandrel 1 is connected with eccentric bushing 6, all is processed with eccentric orfice 5 on the left and right end face of mandrel 1; Compacting part is connected with mandrel 1.Wherein, the eccentric distance e of eccentric orfice 5 just equals the eccentric throw of eccentric bushing 6.
Wherein, compacting part comprises gland 2, screw 3; Be processed with screwed hole on the right side of mandrel 1, gland 2 is connected with mandrel 1 by screw 3.
When the cylindrical to eccentric bushing carries out finish turning, (first with the endoporus of eccentric bushing and both ends of the surface car to requiring, upper slotting machine is inserted out inner hole key slot), eccentric bushing is contained in outside mandrel, compress with gland, the mandrel left end is held in scroll chuck, and left end peaks at eccentric orfice with thimble, right-hand member peaks at eccentric orfice with the tailstock thimble, and then the finish turning excircle of workpiece stays grinding allowance.
When eccentric bushing was carried out grinding, identical with the turning clamping method, just workpiece rotating was by the rotation of heart carrier for bolt clamping mandrel left end band moving mandrel, and the grinding work piece cylindrical is to requiring.
When eccentric bushing is carried out milling, identical with the turning clamping method, determine the position of first locating slot by ruling, the mandrel left end is held in the dividing head scroll chuck, the front and back thimble peaks in eccentric orfice, first groove has milled rear with second groove of dividing head calibration milling, other groove of milling by that analogy.
Adopt the utility model Multifunctional core shaft device, in the eccentric bushing process, it is easy to be accurate to locate, and has both guaranteed crudy, has saved again the clamping centering time, has improved operating efficiency.
