Abstract
The invention relates to the field of mechanical auxiliary devices, in particular to an arc-surface part turning clamp which comprises a mandrel. The arc-surface part turning clamp is characterized in that a back baffle is sleeved on the mandrel and butts against a shaft shoulder disposed on the mandrel. A front baffle capable of sliding on the mandrel is also sleeved on the mandrel. A nut is connected at one end of the mandrel close to the front baffle. A plurality of compression rings are arranged between the nut and the front baffle. The arc-surface part turning clamp is simple in structure and convenient to manufacture, saves production cost, and is applicable to clamping processing of parts whose arc surface rotation center is inconsistent with the rotation center of the parts.
Description
Technical field
The present invention relates to assist field, be specifically related to arc surface accessory turning fixture.
Background technology
In machinery manufacturing industry, often can encounter the processing of arc surface part.Pole plate body is a typical arc surface part, the centre of gyration of this part arc surface and the centre of gyration of workpiece inconsistent, cause arc surface processing difficulty.
The adoptable multiple method of pole plate body arc surface processing.During single-piece production, CNC milling machine of being everlasting carrying out Surface Milling processing, in order to reach the requirement of surface roughness, also needing to carry out reconditioning and polishing by pincers worker after the milling.This processing method processing cost is high, and working (machining) efficiency is low, due to reconditioning hand-manipulated after processing, easily changes arc shape.When small batch is produced, bar can be selected on engine lathe to carry out turnery processing, then grinding outer round surface on cylindrical grinder, polishing is carried out after grinding, after reaching cambered surface part cambered surface radius dimensional requirement and surface roughness requirements, adopt the method for Linear cut that whole bar is cut into 6 pieces, and then carry out the processing of other operation.There is processing charges higher (addition of the expense of Linear cut) in obvious this method, waste of material is large, and allowance causes greatly the feature of long processing time.Therefore should consider to utilize fixture to process for processing more than single-piece.
Summary of the invention
In order to solve the problem, the invention provides a kind of structure simple, easily manufactured, saving production cost, be suitable for the arc surface accessory turning fixture that on part, the arc surface centre of gyration and the inconsistent parts fixation of the centre of gyration of part own are processed.
Arc surface accessory turning fixture of the present invention, comprise mandrel, it is characterized in that, described mandrel is socketed with a backboard, the shaft shoulder on backboard and mandrel offsets, and mandrel is also socketed with a front apron, and described front apron can slide on mandrel, mandrel is connected with a nut on one end of front apron, between described nut and front apron, is provided with some pressure rings.
Preferably, front apron and backboard are provided with some axis holes for matching with workpiece gyroaxis.
Preferably, the axis hole on front apron and backboard is all symmetrical.
Preferably, each the axis hole both sides on front apron and backboard are provided with a shop bolt.
Structure of the present invention is simple, easily manufactured, saves production cost, and is suitable for the arc surface centre of gyration and the inconsistent parts fixation of the centre of gyration of part own on part and processes.

Detailed description of the invention
Arc surface accessory turning fixture of the present invention, comprise mandrel 1, described mandrel 1 is socketed with a backboard 2, backboard 2 offsets with the shaft shoulder on mandrel 1, mandrel 1 is also socketed with a front apron 3, described front apron 3 can slide on mandrel 1, mandrel 1 is connected with a nut 5 on one end of front apron 3, is provided with some pressure rings 4 between described nut 5 and front apron 3.Front apron 3 and backboard 2 are provided with some axis holes for matching with workpiece 6 gyroaxis.Axis hole on front apron 3 and backboard 2 is all symmetrical.Each axis hole both sides on front apron 3 and backboard 2 are provided with a shop bolt 7, add between front apron 3 and backboard 2 and hold workpiece 6, backboard 2, front apron 3 are connected by key with mandrel, and front apron 3, backboard 2 relatively the gyration free degree limit by the key on mandrel l.
As shown in Figure 1, because shoulder place, workpiece 6 two ends is non-workpiece face, drilling can go out two technique pin-and-holes, six axis hole one_to_one corresponding that six axis holes that front apron 3 is evenly distributed and backboard 2 are evenly distributed, for installing the gyroaxis at workpiece 6 two ends, 12 apertures on front apron 3 are all equipped with shop bolt 7, the each shop bolt 7 in each axis hole both sides, during baffle plate 3, shop bolt 7 is inserted in the technique pin-and-hole on workpiece shoulder in a pre-installation, in order to limit the revolution of workpiece 6 around own axes, workpiece 6 is with front, backboard 3, 2 are installed on mandrel l, axially by the shoulder on mandrel 1 and pressure ring 4, nut 5 is located, workpiece 6 is contained in after on clamp body, one end of mandrel 1 is installed on machine chuck, namely the other end can carry out turnery processing with top withstanding, workpiece 6 need not be dismantled after turning directly clamp body can be installed on cylindrical grinder together with workpiece 6 and realize exterior arc surface grinding, polishing is carried out after grinding, after reaching the requirement of workpiece cambered surface, the processing that workpiece carries out other operation is again dismantled from fixture.
