Abstract

The utility model relates to a spindle for positioning work-piece in sleeve type, wherein the middle portion is arranged with a flange (1) which two side end faces are respectively provided with a positioning pin (7, 8) relative to the positioning holes on the end faces of the work-piece, two sides of the flange (1) are connected with two sections of positioning shaft neck (2, 3) which outer diameters are same as the diameter meter of an inner hole on the work-piece and through the axis of the work-piece, the positioning shaft necks (2, 3) are respectively connected with two press shaft necks (4, 5) with external screws, the pressure shaft neck (4) is connected with a transmission shaft neck (6) with three planes uniformly distributed along circumference. The utility model has high practicality for clamping and installing sleeve-type element, which can mount two elements in one time, with high efficiency, wide application, easy application, reliable clamp, simple production and low cost.

Description

The mandrel that is used for axle sleeve class workpiece location
Technical field
The utility model relates to a kind of mandrel that is used for axle sleeve class workpiece location.
Background technology
During processing axle sleeve class part, locate by the endoporus of its axis usually, refill each hole and the face that are clipped in processing circumferencial direction on the lathe behind the clamping work pieces.When the hole of workpiece circumferencial direction and axis have offset distance or offset distance big, can have the very big cutting moment of torque in the working angles, cause because of clamping force less than the cutting moment of torque, workpiece can produce deflection adding man-hour, causes machining accuracy to reduce greatly.
Summary of the invention
The utility model purpose provides a kind of two axle sleeve class workpiece of once can installing, the working (machining) efficiency height, and reliable clamping, easy to use, the positioning core axle of highly versatile.
The mandrel that is used for axle sleeve class workpiece location of the present utility model, mid portion is a flange 1, have respectively on the both sides end face of flange with workpiece end face on the corresponding alignment pin 7,8 of locating hole; What join with flange 1 both sides is two sections locating journals 2,3, and locating journal 2,3 external diameters equal diameter on the workpiece, that cross the endoporus of axis of workpiece; Be two sections the externally threaded axle journal 4,5 that compresses is arranged with locating journal 2,3 joins respectively; With what compress that axle journal 4 joins is at evenly the distribute transmission axle journal 6 on three planes of circumferencial direction.
Locating journal 2 or locating journal 3 are used for the workpiece radial location, and alignment pin 7 on the flange or alignment pin 8 are used for workpiece circumferentially spacing.On the circumferencial direction of transmission axle journal 6 three planes that evenly distribute, the mandrel work in-process is obtained and transmit the peak torque that lathe is given, and the relatively accurate position with lathe of being easy to get when mandrel is installed.
Have centre bore compressing on the axle journal 5, make assist location to use the tailstock thimble.
Described mandrel is divided into two parts vertically at flange 1 place, and two parts 1-1, the 1-2 of flange are connected.This mandrel is divided into two parts, is in order to make this mandrel easy to process, good manufacturability.
Description of drawings
Fig. 1 is the structural representation of the mandrel of present embodiment at two workpiece of installation.
Fig. 2 is the right view of the transmission axle journal 6 among Fig. 1.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Among Fig. 1,2, the mandrel that is used for axle sleeve class workpiece location is divided into left and right sides two parts 9-1,9-2.Left-hand component 9-1 is along axially being that what to link to each other is to have externally threadedly to compress axle journal 5, transition axle journal 11, guiding axle journal 13, connect axle journal 15, locating journal 3, flange 1-1 successively.Left-hand component 9-2 is along axially being that what to link to each other is transmission axle journal 6 successively, having and externally threadedly compress axle journal 4, transition axle journal 10, guiding axle journal 12, connect axle journal 14, locating journal 2, flange 1-2.Flange 1-1,1-2 are by being connected at two circumferential bolts 16 of flange.Transmission axle journal 6 circumferencial directions are three planes of distribution evenly.The central axis place that compresses axle journal 5 has the centre bore (not shown).
Two identical workpiece 17,18 are separately positioned on left and right sides two parts 9-1, the 9-2 of mandrel.Locating journal 2,3 external diameters equal diameter on the workpiece, that cross the endoporus (locating hole) 21 of axis of workpiece.
Have on the side end face of flange 1-1 two with workpiece 17 end faces on locating hole 19 corresponding alignment pins 7; Have on the side end face of flange 1-2 two with workpiece 18 end faces on locating hole 20 corresponding alignment pins 8.
Locating journal 2 (3) is used for workpiece 18 (17) radial locations, and two alignment pins 8 (7) are used for workpiece 18 (17) circumferentially spacing.Nut 22 (23) and the threaded engagement that compresses on the axle journal 4 (5) are used for workpiece 18 (17) along axial compression.The guide effect that guiding axle journal 12 (13) plays vertically workpiece 18 (17).
This mandrel is very practical in the clamping of axle sleeve class part, and two parts once can be installed, and has the working (machining) efficiency height, and highly versatile is easy to use, and reliable clamping is made simply economical and practical characteristics.

Claims (3)

1. be used for the mandrel of axle sleeve class workpiece location, it is characterized in that: the intermediate portion is flange (1), have respectively on the both sides end face of flange with workpiece end face on the corresponding alignment pin of locating hole (7,8); What join with flange (1) both sides is two sections locating journals (2,3), and locating journal (2,3) external diameter equals diameter on the workpiece, that cross the endoporus of axis of workpiece; Be two sections the externally threaded axle journal (4,5) that compresses is arranged with locating journal (2,3) joins respectively; With what compress that axle journal (4) joins is at evenly the distribute transmission axle journal (6) on three planes of circumferencial direction.
