Abstract
The utility model relates to a shaft part axial-positioning device relating to the technical field of positioning devices. The shaft part axial-positioning device comprises a positioning device body, a floating tip, a positioning reference block and a tailstock tip, wherein one end of the positioning device body is provided with the floating tip and the positioning reference block, and the other end is provided with the tailstock tip; and the floating tip is internally provided with a spring. The shaft part axial-positioning device has high practicability, is convenient to use, ensures the accurate positioning of a cam shaft in an axial direction and ensures that left-side and right-side machining allowances are consistent to actual process design, thereby enhancing the quality of products and preventing from cutter damage and workpiece scrapping which are caused by the problem of the machining allowances; the shaft part axial-positioning device ensures the uniform stress of clamping jaws, thereby greatly reducing the maintenance cost and enhancing the work efficiency; and in addition, the shaft part axial-positioning device is applied to the lathe machining process of the cam shaft of a GEVO16 diesel engine.
Description
Technical field
The utility model relates to a kind of technical field of positioner, especially a kind of axial workpiece axial direction positioning device.
Background technology
Original axial workpiece is when numerical control turning, in order to reduce one turner skill boss operation, at the two ends of blank centering, with centre bore as the location benchmark, but because axle two ends center hole size has difference, be difficult to guarantee axle accurate positioning in the axial direction, easily because of turning add man-hour both ends of the surface allowance uneven to cause blade to collapse broken, that have even monolateral can't process of blank occur and cause blank to scrap, another problem is exactly that claw is not clamped to workpiece fully, makes the claw local pressure excessive and the phenomenon of bursting apart often occurs.
The utility model content
Be difficult to accurate positioning, the excessive deficiency of claw local pressure in order to overcome original positioner, the utility model provides a kind of axial workpiece axial direction positioning device.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of axial workpiece axial direction positioning device, comprise the positioner body, top, location reference block and tailstock centre float, positioner body one end is provided with and floats top and the location reference block, and the other end is provided with tailstock centre.
According to another embodiment of the present utility model, further comprising floats is provided with spring in top.
The beneficial effects of the utility model are: this axial workpiece axial direction positioning device is easy to use, practical, guaranteed camshaft accurate location in the axial direction, and about the design of each side allowance and actual process consistent, improved the quality of product, tool damage and the workpiece of having avoided the problem owing to allowance to cause are scrapped, guarantee that claw is stressed evenly, greatly reduce maintenance cost, improved operating efficiency, simultaneously, this axial workpiece axial direction positioning device has been applied to the turning manufacturing procedure of GEVO16 cam shaft for diesel engine.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model;
1. positioner bodies among the figure, it is top 2. to float, 3. location reference block, 4. tailstock centre, 5. spring.
The specific embodiment
In conjunction with the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
As Fig. 1 is structural representation of the present utility model, this axial workpiece axial direction positioning device comprises positioner body 1, it is top 2 to float, location reference block 3 and tailstock centre 4, positioner body 1 one ends are provided with and float top 2 and location reference block 3, the other end is provided with tailstock centre 4, floats to be provided with spring 5 in top 2.
During use, install and axially movablely to float top 2 in chuck-end, groove on the workpiece that needs to process can guarantee workpiece left and right sides allowance unanimity, float top 2 and 4 pairs of workpiece of tailstock centre carry out centralized positioning, at this moment, tailstock centre 4 is exerted pressure, the feasible top 2 interior springs 5 that float are under pressure and are out of shape, thereby driving unsteady top 3 moves axially, the size of amount of movement is by the pressure and 3 decisions of location reference block of tailstock centre 4, make axial internal clearance bigger than center hole tolerance in the axial direction, guarantee simultaneously that before tailstock centre 4 not being exerted pressure the end face in maximum hole does not contact with location reference block 3, after tailstock centre 4 is exerted pressure, the end face in minimum hole can contact with location reference block 3, to guarantee all claws holding workpiece fully.This axial workpiece axial direction positioning device is easy to use, practical, guaranteed camshaft accurate location in the axial direction, and about the design of each side allowance and actual process consistent, improved the quality of product, tool damage and the workpiece of having avoided the problem owing to allowance to cause are scrapped, guarantee that claw is stressed evenly, greatly reduce maintenance cost, improved operating efficiency, simultaneously, this axial workpiece axial direction positioning device has been applied to the turning manufacturing procedure of GEVO16 cam shaft for diesel engine.
With above-mentioned foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the specification, must determine its technical scope according to the claim scope.
