Description

A kind of camshaft roughly grinds fixture
Technical field
The present invention relates to machining technique field, more particularly to a kind of camshaft corase grinding fixture.
Background technology
With the development of Chinese mechanical industry, more and more mechanical processing techniques are had been widely used in various production lines On.
Mechanical processing mainly has two major class of manual processing and digital control processing, and manual processing refers to grasp by hand by mechanic Make the mechanical equipments such as milling machine, lathe, drilling machine and sawing machine to realize the method being processed to a variety of materials, manual processing be adapted into Row small lot, the production of simple part.Digital control processing (CNC, Computer numerical control) refers to mechanic It is processed with numerical control device, these numerical control devices include machining center, turning milling center, Wire EDM equipment, spiral shell Line cutter etc..Most of machine shop all uses Computerized Numerical Control processing technology, by programming, workpiece in cartesian coordinate Position coordinates (X, Y, Z) in system is converted into program language, and the CNC controller of numerically-controlled machine tool passes through identification and interpreter language To control the axis of numerically-controlled machine tool, material is removed on request automatically, so as to obtain finishing workpiece.Digital control processing is in a continuous manner Carry out workpieces processing, be suitable for high-volume, complex-shaped part.Machine shop can use CAD/CAM (CADs Computer-aided manufacturing) system is automatically switched to CAM systems to programming of CNC machine, the geometry of part from CAD system System, mechanic select various processing methods on virtual display screen.After mechanic selectes certain processing method, CAD/ CAM system can export CNC code automatically, and code is input in the controller of numerically-controlled machine tool and is grasped with carrying out actual processing Make.
Grinding machine is for the common lathe in grinding process, when machining cam axis is when revolving meber, it is necessary to pass through grinding machine pair Roughly ground on the surface of camshaft.When being ground using grinding machine to the surface of camshaft, it is necessary first to workpiece into luggage Folder, avoids vibrating or running during processing flying.At present, when roughly grinding camshaft, clamping is generally carried out using separating clamp, i.e., must be first It is installed to by camshaft clamping to pre-prepd fixture, then by the fixture on grinding machine, both of which carries out after installation is complete again Grinding.However, the clamping process of such a installation way is troublesome, cumbersome, and clamping efficiency is relatively low.
Therefore, the clamping operation to camshaft how is quickly and easily completed, reduces clamping flow, improves clamping efficiency, It is those skilled in the art's technical problem urgently to be resolved hurrily.
The content of the invention
The object of the present invention is to provide a kind of camshaft to roughly grind fixture, can quickly and easily complete the dress to camshaft Folder operation, reduces clamping flow, improves clamping efficiency.
In order to solve the above technical problems, the present invention provides a kind of camshaft corase grinding fixture, including be connected with grinding machine spindle Terminal pad and the chuck being arranged on the terminal pad outer surface, if being provided with what can be radially slided on the surface of the chuck The dry claw for being used for gripping cams shaft end outer wall, it is axially disposed on the surface of the chuck to have mounting hole, the installation Be provided with hole for be inserted into camshaft mandrel end inner cavity and with its abut before it is top;Further include and be arranged at the afterbody of grinding machine, use In the back centre for being inserted into camshaft the other end inner cavity and being abutted with it, and the preceding top and back centre is coaxially distributed.
Preferably, further include and be arranged at grinding machine surface, top the branch of camshaft is abutted, be used to support with the outer wall of camshaft Bracketing frame.
Preferably, further include be arranged on the clamping face of the claw, for on camshaft reserved groove coordinate with In gripping cams axis to its pinpoint locating piece.
Preferably, the circumferential position on the chuck surface around the mounting hole is provided with connector sleeve, and the sinciput The outer wall of point is installed in the connector sleeve.
Preferably, the chuck is specially air spider, and is provided with the inner wall of the mounting hole for the card Disk forms the sealing shroud of hermetic seal.
Preferably, ring flange is connected with the surface of the grinding machine spindle, and between the ring flange, terminal pad and chuck Interconnected by fastener.
Preferably, the driving key for forming key transmission with the ring flange is provided with the surface of the grinding machine spindle.
Camshaft provided by the present invention roughly grinds fixture, mainly including terminal pad, chuck, preceding top and back centre.Wherein, Terminal pad is connected with grinding machine spindle, can under the drive of grinding machine spindle synchronous rotary.Chuck is arranged on the outer surface of terminal pad On, can under the drive of terminal pad synchronous rotary.Several claws that can radially slide are provided with the surface of chuck, respectively A claw is mainly used for clamping the end outer wall of workpiece (camshaft) from circumferential direction.It is axially disposed on the surface of chuck at the same time There is mounting hole, it is top before being provided with the mounting hole, for being inserted into clamping camshaft in the end inner cavity of camshaft, And by its tightly against.Back centre is arranged on the afterbody of grinding machine, is mainly used for being inserted into camshaft in clamping camshaft another In the inner cavity of end, and by it tightly against and the coaxial distribution of both preceding top and back centres, i.e., central axes are conllinear.In this way, Camshaft provided by the present invention roughly grinds fixture, when carrying out corase grinding processing to camshaft, only needs directly by the both ends of camshaft End inner cavity is caught on preceding top and back centre and pushes against, then the end outer wall by each claw gripping cams axis on chuck, It can be achieved to operate the clamping that camshaft to be mounted directly on grinding machine, need to only start grinding machine spindle afterwards can drive camshaft Rotation, is normally carried out grinding.Compared with the prior art, the present invention without by additional fixture first to camshaft into luggage It is installed to again on grinding machine after folder, therefore can quickly and easily completes the clamping operation to camshaft, is reduced clamping flow, carry High clamping efficiency.
