Description
Technical field
The utility model relates to a kind of exclusive clamps locking structure, specifically, is a kind of lathe lasso formula centre frame that is used to process some outer round belt conical surfaces or the longer thin-walled parts of cambered surface.
Background technology
In machine-building, long axial workpiece is added man-hour, the self-centering centre frame that carries out clamping to outer circumference surface commonly used to axial workpiece.Its generally comprise base, have in the base bottom with the corresponding chute of machine tool guideway, be arranged on the locking device on the lathe of base can being locked on the base, and the chuck that is rotationally connected with base.But for the outer round belt conical surface or cambered surface man-hour that adds, need the cylindrical of holding workpiece than the port endoporus of elongated workpieces and internal thread, because the outer round belt conical surface of part or cambered surface, can't clamping with common self-centering centre frame.Also once adopted in the past a lot of clamping means and clamping device to occur, but all because of the too high of manufacturing cost or because of the complicated of its structure and exchange that to differ from effect undesirable.
Summary of the invention
The utility model solves is that existing common self-centering centre frame can not clamping has the problem that the conical surface or cambered surface part are processed, for people provide a kind of can be to the lasso formula centre frame that carries out radial centering and axially clamp than elongated workpieces of the conical surface or cambered surface.
A kind of lasso formula of the utility model centre frame, comprise base, have in the base bottom with the corresponding chute of machine tool guideway, be arranged on the locking device on the lathe of base can being locked on the base; It also comprises the bearing material circle coaxial with machine tool chief axis, and bearing material circle and base top are rotationally connected, and its inner chamber is taper type.
The following describes its using method and operation principle.During use, the outer conical surface or the cambered surface of part to be processed are extend in the bearing material circle, and move the bearing material circle along machine tool guideway, make the inwall of taper type of bearing material circle contact with the outer conical surface or the cambered surface of part, then by locking device with base locking (fixing) on lathe.Under the drive of machine tool chief axis, part to be processed and bearing material circle rotate with respect to base together, cutter can to the port endoporus of part or and internal thread process.The utility model has promptly been realized carrying out radial centering and axially clamping than elongated workpieces the conical surface or cambered surface.
Above-mentioned arbitrary lasso formula centre frame, the bearing material circle can rotate by angular contact ball bearing and base; Preferably it also comprises the splicing sleeve that is arranged between bearing material circle and the angular contact ball bearing, and the bearing material circle becomes to removably connect with splicing sleeve.Dismountable connected mode can be changed the different bearing material circle of intracavity section shape and size, easily to be applicable to the processing of the part that has the different conical surfaces or cambered surface.
Above-mentioned arbitrary lasso formula centre frame, it also can comprise the transmission mechanism that links to each other with base, the drive base slides along guide rail.By setting up the transmission mechanism that belongs to prior art, can drive base and slide, thereby can more reliably part axially be clamped so that base applies bigger axial force by the bearing material circle to part to be processed along guide rail.Transmission mechanism can be varied, as oil cylinder, cylinder, pinion and rack etc.
Locking device also has in common self-centering centre frame, belongs to prior art, and its function is centre frame to be locked (fixing) on lathe, makes centre frame not move with respect to guide rail.Locking device in the utility model, comprise and be connected on the base and pressing plate, latching ram that its upper surface is relative with the machine tool guideway lower surface, latching ram slides up and down and is connected with driving pilot hole at the pressing plate upper surface, and the pilot hole bottom communicates with oil pocket in the pressing plate, and oil pocket communicates with the oil circuit import.When needs were locked, pressure oil entered oil pocket by the oil circuit import, with latching ram jack-up, made latching ram move up to compress into the lower surface of guide rail, had promptly realized locking function.

The specific embodiment
Referring to accompanying drawing, the utility model by base 1, blind flange 2,5,8, splicing sleeve 3, angular contact ball bearing 4, oil cylinder 13, bearing material circle 10, and locking device 6,7 constitute.Angular contact ball bearing 4 is arranged in the perforate of base 1 top institute, and its outer ring is axially contacting with the blind flange 2,3 that is fixed on by screw on the base respectively, and its inner ring is sleeved on outside the splicing sleeve 3.The bearing material circle 10 coaxial with machine tool chief axis removably is contained in the splicing sleeve 3 by screw, and its inner chamber is taper type, and its outer wall matches with the shape of splicing sleeve 3 inwalls.The bottom of base 1 has and is used to be installed in machine tool guideway 9 upper hopper chutes 18.The piston rod of oil cylinder 13 is hinged on the base bottom, can move around along guide rail at the effect lower bottom base 1 of oil cylinder 13.
Two locking devices 6,7 include pressing plate 14, latching ram 15.Pressing plate 14 is connected on the base by screw 19.On the upper surface of the pressing plate relative, have the pilot hole 20 that latching ram is set with the machine tool guideway lower surface, slide up and down with pilot hole along a plurality of latching rams 15 of the length arrangement of guide rail and to be connected, oil pocket 16 in pilot hole bottom and the pressing plate communicates, and oil pocket 16 communicates with oil circuit import 17.Oil circuit import 17 is used for communicating with the hydraulic control system of lathe, start the hydraulic control system of lathe when needing, hydraulic oil is pressed into oil pocket 16 by oil circuit import 17, oil pocket is full of, latching ram upwards rises under the effect of hydraulic system pressure oil, base can be locked on the machine tool guideway 9 fast.
The utility model can be furnished with the different bearing material circle of a plurality of intracavity section shape and size, to be applicable to the processing of the part that has the different conical surfaces or cambered surface.
Operation principle of the present utility model is: during use, the outer conical surface or the cambered surface of part to be processed are extend in the bearing material circle, and move the bearing material circle along machine tool guideway, make the inwall of taper type of bearing material circle contact with the outer conical surface or the cambered surface of part, then by locking device with base locking (fixing) on lathe.Under the drive of machine tool chief axis, part to be processed and bearing material circle rotate with respect to base together, cutter can to the port endoporus of part or and internal thread process.
Referring to Fig. 1, part 11 1 ends are clamped by machine chuck 12, and the other end becomes cambered surface.The bearing material circle is coaxial with part 11, and oil cylinder 13 drives base to being moved to the left along guide rail under the machine tool hydraulic system fuel feeding, and bearing material circle inner surface contacts with the arc-shaped outer surface of part 11, realizes the radial centering of part and axially clamping.Then, by locking device base is locked at machine tool guideway fast.Oil cylinder 13 changes the size of part axial clamping force by the pressure adjustment of machine tool hydraulic system.Machine tool chief axis drives part 11, bearing material circle 10, splicing sleeve 3, the inner ring of angular contact ball bearing 4, blind flange 8 and turn round together, and the inner ring of angular contact ball bearing 4, blind flange 2,5 transfixions, realization is to the processing of working position.
The utility model is simple in structure, with low cost, it is easy to use to adjust and have good interchangeability, solved the outer round belt conical surface or cambered surface than elongated workpieces processing endoporus the time clamping cylindrical problem.
