Abstract
The utility model relates to a device for automatically centering and clamping shaft parts. The device comprises a body, an end face thrust bearing, a first rolling bearing, a chuck jacket, a spring chuck, a fixing screw, a special lining, a second rolling bearing and a gland, wherein one end of the body is fixedly connected with the closed end of the special lining; the thrust bearing, the spring chuck, the chuck jacket, the first rolling bearing and the second rolling bearing are arranged in an inner hole of the special lining in sequence; the gland is arranged between the end part of open end of the special lining and the chuck jacket, so that the thrust bearing is positioned between the inner end face of the closed end of the special lining and the end face of the chuck jacket; and an inner hole of which the external diameter corresponds to that of a workpiece is formed in the center of the spring chuck. The device has a reasonable structure and is high in positioning accuracy and convenient to use and maintain, the principle is reliable, and the parts are easy to clamp; and when long and thin shaft parts are machined on the common lathe or a numerical control lathe, the machining accuracy of the machined parts can be effectively ensured.
Description
Technical field
The utility model relate to a kind of on engine lathe or numerically controlled lathe the self-alignment cramping arrangement of processing thin and long shafts parts, belong to mechanical processing technique device technique field.
Background technology
Axial workpiece refers to the rotary body part, and length is one of typical part that often runs in the machining greater than diameter, and its effect is in machine, to support driving parts, bearing load.The principal element that influences its machining accuracy in the axial workpiece production process has: the rotating accuracy of machine tool chief axis, the precision of rectilinear motion of moving-member, cutting-in drag produce distortion etc. to workpiece; For the high thin and long shafts part turning processing of required precision; The principal element that influences its machining accuracy is the cutting-in drag; In order to satisfy the design accuracy requirement, anchor clamps that must design special, it is good with vehicle clamper Installation and Debugging on lathe to add man-hour; Again this parts fixation is processed to vehicle clamper, to reduce the influence that the cutting-in drag produces workpiece as far as possible.
The utility model content
The purpose of the utility model is to the demand, and a kind of convenient mounting and clamping is provided, and the axial workpiece self-alignment cramping arrangement of accurate positioning is to improve the machining accuracy of thin and long shafts parts.
The said clamping device of the utility model comprises body, end face thrust bearing, first rolling bearing, chuck overcoat, collet, hold-down screw, special-purpose lining, second rolling bearing and gland; Said body one end is fixedly connected with the blind end of special-purpose lining; Installed thrust bearing, collet, chuck overcoat successively in the special-purpose lining endoporus; First rolling bearing and second rolling bearing; Between special-purpose lining openend end and the chuck overcoat gland is installed, is made thrust bearing between special-purpose lining blind end inner face and chuck overcoat end face, the collet center is provided with the endoporus corresponding with the workpiece external diameter.
Between said gland and the chuck overcoat sealing gasket is housed.
Collet radially is connected fixing with the chuck overcoat through hold-down screw.
The utility model self-alignment cramping arrangement design principle is reliable, and is rational in infrastructure, and clamping is simple, and positioning accuracy is high, and working service is convenient.On engine lathe or numerically controlled lathe, during the processing thin and long shafts parts, use the machining accuracy that this self-alignment cramping arrangement can effectively guarantee institute's process component.
Description of drawings
Fig. 1 is the novel self-alignment cramping arrangement structural representation of the utility model.
Among the figure: 1-body, 2-end face promote bearing, 3-first rolling bearing, 4-chuck overcoat, 5-collet, 6-hold-down screw, the special-purpose lining of 7-, 8-second rolling bearing, 9-gland, 10-sealing gasket.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further explain:
As shown in the figure; The said clamping device of the utility model comprises body 1, end face thrust bearing 2, first rolling bearing 3, chuck overcoat 4, collet 5, hold-down screw 6, special-purpose lining 7, second rolling bearing 8 and gland 9; Said body 1 one ends are fixedly connected with the blind end of special-purpose lining 7; Installed thrust bearing 2, collet 5, chuck overcoat 4 successively in special-purpose lining 7 endoporus; First rolling bearing 3 and second rolling bearing 8; Between special-purpose lining 7 openend ends and the chuck overcoat 4 gland 9 is installed, is made thrust bearing 2 between special-purpose lining 7 blind end inner faces and chuck overcoat 4 end faces, collet 5 centers are provided with the endoporus corresponding with the workpiece external diameter.For increasing this device sealing, guarantee the bearing operate as normal simultaneously, this device is equipped with sealing gasket 10 between said gland 9 and chuck overcoat 4.Collet 5 radially is connected through hold-down screw 6 with chuck overcoat 4 to be fixed, and it is convenient to change.
Among the embodiment, end face thrust bearing 2 selects that specification 8201 bearings, rolling bearing 3 are 207, rolling bearing 8 is 208 for use.
Use the utility model on lathe, during processing work, to need clamping shelves cylindrical clamping on the scroll chuck of Lathe Spindle Box end the workpiece of being processed earlier, clamp claw, simultaneously clamping work pieces.Then the Morse's taper of the utility model self-alignment cramping arrangement through its body 1 shank is assemblied on the tail centre seat of engine lathe or numerically controlled lathe; Locomotive tailstock dead head; Workpiece afterbody clamping shelves are inserted in collet 5 endoporus of this self-alignment cramping arrangement; The workpiece tail end face promotes collet 5 and moves to right, and collet 5 compressions are tightened up and clamping work pieces.Fixedly behind the dead center seat, can carry out the processing of each grade of workpiece cylindrical.
The utility model is based on the self-alignment cramping arrangement in engine lathe design, can eliminate that the cutting-in drag makes workpiece produce the problem of distortion in the thin and long shafts part process, and low cost of manufacture, debugging is easy, service behaviour is safe and reliable;
Part machining accuracy easy to loading and unloading is higher, can satisfy the machining slender shaft required precision, and the surface flatness of institute's converted products also can meet the demands.After the product completion of processing, remove this device, can recover to become engine lathe, bring into play the purposes of engine lathe again, can accomplish special, general dual-purpose, thereby made full use of enterprise's existing equipments resources, reach the purpose that reduces production costs.
Simultaneously, this self-alignment cramping arrangement in use can be according to the excircle dimension of institute's processing work clamping shelves size, and dissimilar collets 5 is changed in design, can process dissimilar thin and long shafts parts.
