Description
Technical field
The utility model relates to a kind of turning attachment, particularly relates to a kind of parts processing the fixture of cover parts on lathe.
Background technology
When lathe is processed cover parts, there is so class part, the endoporus of its one end does not need processing, and cylindrical and end face need processing, the endoporus of the other end needs processing, and cylindrical and end face are not processed, existing tension mechanism cannot meet the processing that clamped one time completes one end cylindrical, end face and other end endoporus; After needing clamping, after completing the processing of one end cylindrical and end face, clamping again, completes the processing of other end endoporus; Waste time and energy, and even a fixture can not complete processing tasks, needs multiple stage fixture, considerably increases processing cost.
Utility model content
The purpose of this utility model solves the above-mentioned problems in the prior art exactly, a kind of pushing-type blank hole swelling device for cover parts processing is provided, it does not need processing to the endoporus of one end, and cylindrical and end face need processing, the endoporus of the other end needs processing, and after cylindrical and end face do not need the tensioner of the workpiece processed to support, once can complete the processing of one end cylindrical of this workpiece, end face and other end endoporus, time saving and energy saving, greatly reduce processing cost.
For achieving the above object, technical solution of the present utility model is: a kind of pushing-type blank hole swelling device for cover parts processing, and it comprises matrix, fixed axis, push rod, movable tapered sleeve, pin, disc spring, ringfeder, flexible block and position block; Have centre bore in matrix, centre bore internal fixtion is provided with fixed axis; Fixed axis latter half has center chute, and centre has vertical slide opening, and front end reducing is the taper of rising matched with the conical surface of ringfeder inner circle front end of spreading forward; In the center chute that push rod is through fixed axis and can along slide, its leading section be positioned at the vertical slide opening of fixed axis; Movable tapered sleeve front end cylindrical inwardly shrinks and matches with the conical surface of ringfeder inner circle rear end, and it is enclosed within outside fixed axis, and rear end is fixed together by pin and push rod, and pin is positioned at the vertical slide opening of fixed axis and can slides along slide opening; Be disc spring holding tank between the forward and backward taper of ringfeder inner circle, the length of this disc spring holding tank is slightly shorter than the distance that movable tapered sleeve front end face and central shaft rise between tapering point rear end face; What ringfeder was enclosed within movable tapered sleeve front end and fixed axis rises on tapering point, and the workpiece of its cylindrical and cover parts does not need one end endoporus processed to match, and has the disc spring be enclosed within fixed axis in the ringfeder disc spring holding tank of movable tapered sleeve front end face; The flexible block that the endoporus of the workpiece of cylindrical and cover parts matches is fixed on fixed axis front end face; Position block rear end end face diameter is not less than the internal diameter with the absorption surface position of cover parts, and front end is fixed with the Mohs cone bar that can be arranged on tail stock.
The structure that fixed axis described above is fixedly mounted in matrix centre bore is: described fixed hub is in the base in central hole, rear end is fixed on the step of matrix centre bore by pad, hold-down nut and locking nut, for preventing fixed axis from rotating, be fixed with two and above holding screw holds out against on fixed axis in the surrounding of matrix cylindrical.
Flexible block described above is the metallic sheath that the endoporus of the cylindrical of a back-end closure and the workpiece of cover parts matches, its rear end leans out the boss that has endoporus, the holddown groove front end that the external diameter of boss and fixed axis front end face have matches, and holddown groove rear end is the tapped blind hole that internal diameter is less than front end; The boss of metallic sheath is placed in the holddown groove front end of fixed axis, is fixed in the tapped blind hole of holddown groove rear end by screw, and on the screw of holddown groove front end, cover has spring.The active force that this flexible block applies the workpiece of cover parts is very little, can not cause the distortion of the workpiece of cover parts, and its cost is low, is easy to processing.
Position block rearward end described above has blind hole, and the diameter of blind hole is less than the internal diameter with the absorption surface position of cover parts, and the front end of its Mohs cone bar has another blind hole.Two blind holes are all to reduce the contact area with other attaching parts, reducing the active force brought to other attaching parts.
During use, matrix of the present utility model is arranged on lathe spindle, position block is installed on tail stock, push rod is connected with the rotary oil cylinder pull bar that lathe is installed, after the workpiece of cover parts is inserted in ringfeder, under the effect of flexible block, make workpiece be adjacent on the position block of front end, flexible block also plays the effect of buffering, reduces the infringement to workpiece.Push rod travels forward, first by the effect of disc spring, the tapering point that rises on the front end internal conical surface of ringfeder and fixed axis is interacted, make the front end tensioner workpiece of ringfeder, along with the continuation of movable tapered sleeve moves forward, cylindrical and the ringfeder rear end internal conical surface of movable tapered sleeve interact, make the rear end also tensioner workpiece of ringfeder, before ringfeder, between the cylindrical of rear end and workpiece, before ringfeder, all without gap between the cylindrical of rise tapering point and the movable tapered sleeve of rear internal conical surface and fixed axis, so when the position block be installed on tailstock when front end is withdrawn, workpiece still can keep static, and there is no axial play, the processing of cylindrical and end face can be carried out to workpiece rear end, can also process the endoporus of workpiece front end, its clamped one time just can complete the whole processing to workpiece, time saving and energy saving, greatly reduce processing cost.
