Description
Technical field
The present invention relates to a kind of grinding fixture and method for grinding, in particular to a kind of grinding work for outside framework oil seal position
Dress and method for grinding.
Background technique
In the prior art, the grinding at workpiece outside framework oil seal position, needs grinding machine to be ground, and is on grinding machine when grinding
Workpiece outside framework oil seal position is ground with grinding wheel, workpiece slowly runs, so that grinding wheel carries out workpiece outside framework oil seal position
Grinding, the step of grinding to the outside framework oil seal position of cylindrical work are as follows: first carry out turnery processing, processing to workpiece on lathe
After the completion, workpiece is taken off from lathe, then is installed on the workbench of grinding machine, carry out grinding；
Cylindrical work includes cylindrical work ontology and the integrally formed annular convex platform of cylindrical work ontology, then is installed
Onto Grinder bench, with table centering machining benchmark, it is desirable that machining benchmark bounce is less than 0.01mm；Then to workpiece outside framework oil seal
Position is ground.
Above-mentioned grinding method is primarily present following defect:
1), cylindrical work and oil sealing contact portion surface roughness press GB1031-83, and Ra is not small no more than 0.63 μm
Grinding wheel is not allowed to move axially when 0.2 μm (▽ 7- ▽ 9), processing, conventional grinding machine is difficult to accomplish so low roughness, needs
The higher grinding machine of service precision is ground outside framework oil seal position, and the higher grinding machine equipment price of precision is more expensive, equipment
Higher operating costs；
2), in grinding, it is necessary first to carry out centering to workpiece and grinding machine upper table, that is, to guarantee workpiece and work
Make the concentricity of platform, centering efficiency is lower, and time waste is more.
Summary of the invention
The present invention in view of the deficiency of the prior art, provides a kind of grinding fixture for outside framework oil seal position,
The tooling can be mounted on lathe, not need to be ground outside framework oil seal position using grinding machine, substantially reduce mill
It is whittled into this, and the workpiece centering time can be reduced, greatly improves grinding efficiency.
The technical scheme to solve the above technical problems is that a kind of grinding fixture for outside framework oil seal position,
Including clamping bar and oilstone, guide part is equipped between the clamping bar and the oilstone, the guide part can drive the oilstone
Transverse shifting, the clamping bar can be directly installed on lathe.
The beneficial effect of grinding fixture is: entire grinding fixture can be directly mounted on lathe, it is no longer necessary to which grinding machine is to work
Part outside framework oil seal position is ground, and can be ground to workpiece outside framework oil seal position using lathe, lathe equipments price compared with
It is low, save equipment cost；In addition, not needing to dismantle workpiece, it is only necessary in vehicle after on lathe to workpiece turning
Grinding fixture is installed on bed to carry out grinding action to the workpiece after turning, can be guaranteed same between workpiece and workbench
Axis degree, workbench are discoid, it is no longer necessary to which centering, grinding efficiency are higher.
Further, the clamping bar includes bar portion and head, and the head is equipped with cavity, and the guide part can be in the sky
Intracavitary transverse shifting.
Further, the bottom of the cavity is equipped with the first spring stack, and the guide part includes from rear to preceding sequentially connected
Second spring column, positive stop lug boss and slide bar, the second spring column and the first spring stack are corresponding, and first spring stack and
Second spring column sleeve is connected to spring, and the front end of the cavity is equipped with end cap, the slide bar pass through after the end cap with the oilstone
Connection.
Beneficial effect using above-mentioned further technical solution is: when being ground to workpiece outside framework oil seal position, leaning on
The elastic force of spring provides contact force for oilstone and outside framework oil seal position, guarantee oilstone during grinding always with outside framework oil seal
Position is in contact, and ground effect is good, precision is high.
Further, clearance fit between the positive stop lug boss and the cavity, gap between the slide bar and the end cap
Cooperation.
Beneficial effect using above-mentioned further technical solution is: when being ground workpiece, oilstone itself can be lost oilstone, lead
Oilstone surface irregularity is caused, grinding workpiece surface finish can be made bad；And clearance fit, slide bar between positive stop lug boss and cavity
The clearance fit between end cap, allows oilstone fine motion up and down, and oilstone fine motion up and down can increase oil as far as possible
Stone surface and work piece interface product, keep grinding steady, also make oilstone surface loss more uniform, and then guarantee the coarse of grinding
Degree.
Further, the oilstone is fixedly mounted on oilstone disk, and the oilstone disk is fixedly connected with the slide bar.
Further, the guide part is structure as a whole.
Further, the bar portion can directly clamping on lathe.
The invention further relates to a kind of method for grinding for outside framework oil seal position, which comprises the steps of:
Step 1 is finished workpiece turning using lathe；
Above-mentioned grinding fixture is mounted on lathe by step 2, and clamping bar is specially mounted on lathe, oilstone contact
And the outside framework oil seal position of alignment pieces；
Step 3, lathe drive workpiece rotation, and oilstone is constantly ground the outside framework oil seal position of workpiece, until reaching
Grinding requires.
The beneficial effect of method for grinding is: entire grinding fixture is directly installed on lathe, it is no longer necessary to which grinding machine is to workpiece
Outside framework oil seal position is ground, and can be ground to workpiece outside framework oil seal position using lathe, and lathe equipments price is lower,
Save equipment cost；In addition, not needing to dismantle workpiece, it is only necessary in lathe after on lathe to workpiece turning
Upper installation grinding fixture can carry out grinding operation to the workpiece after turning, can guarantee coaxial between workpiece and workbench
Degree, it is no longer necessary to which centering, grinding efficiency are higher.
