Description
Technical field
The invention belongs to the external diameter grinding machine technical field, specially refer to a kind of external diameter grinding machine with the cylinder pressurization.
Background technology
External diameter grinding machine is a kind of finish machining equipment of very economical practicality, is a kind of polishing processing method commonly used in the Production of bearing with this machine grinding shaft bearing ring external diameter.As everyone knows, the external diameter of bearing outer ring, carries out attrition process and can improve its geometric accuracy greatly after mill processing as the datum level of raceway groove processing, reduces surface roughness, for the back operation provides the fine finishining benchmark.
The grinding principle of external diameter grinding machine as shown in Figure 1.During work, workpiece places between the big or small deflector roll, and the pressure F that pressue device produces acts on oilstone, and two deflector rolls rotate to same direction with same angular speed, and pressure F continues to exert pressure to workpiece by pressue device, oilstone and clamping plate.Because the axle center of big or small deflector roll is adjustable as required at the mutual angle of level and vertical plane, so rotation along with two deflector rolls, workpiece will go forward one by one continuously along its axis direction and move, meanwhile, the operator brushes grinding agent every now and then on little deflector roll, so that workpiece at the volley, by the effect of pressure F, the external diameter surface sassafras that rubs that is squeezed repeatedly, thus reach the purpose of grinding.
By above-mentioned process of lapping as can be known, pressue device controlled pressure F is wherein indispensable link.Pressure F must be according to the size of workpiece outside dimension, and the processing request of thick, lappingout etc. carries out suitable adjustment.
At present, the external diameter grinding machine that bearing industry is used grinds the lasso external diameter generally below φ 150mm, and the pressure during work is to be applied pressure on the workpiece by deadweight by one group of counterweight.According to grinding needs, to suitably increase and decrease counterweight weight on the one hand, on the other hand, the support of counterweight is installed, i.e. workpiece pressurization center need be with the size of workpiece external diameter, about the work, move forward and backward, can act on all the time directly over the workpiece to guarantee pressure F.Therefore, the counterweight support need be installed on the two cover slides.
For the big external diameter lasso of processing, be the external diameter grinding machine of φ 150～φ 300mm as diameter, the counterweight pressuring method is impracticable.Because, the lasso external diameter strengthens, the also corresponding increasing of external diameter of size two deflector rolls, about the pressurization center, front and back adjustment distance all increased manyly, therefore, the complexities of two cover slide carriage mechanisms strengthen, thereby make complete machine structure huge, make processed complex, adjust troublesome poeration, use very inconvenient.
Summary of the invention
In order to address the above problem, the invention provides a kind of external diameter grinding machine with the cylinder pressurization, this machine can be used for grinding the bearing ring of P4 level, the lasso maximum outside diameter is φ 300mm, grinding effect is fine, simple in structure because of it, economical and practical, have good application value at bearing and other mechanical processing industry.
In order to realize the foregoing invention purpose, the present invention has adopted following technical scheme:
Described external diameter grinding machine with the cylinder pressurization, its method is that three cylinders are fixed on the support plate that can move forward and backward, support plate is installed on the big deflector roll seat, and the flexible hold down gags of the piston rod external part of three cylinders and three connect, and can drive it and do the upper and lower of big stroke and move; Flexible hold down gag adds and is pressed on the oilstone clamping plate, transmission system is with greatly during grinding, little deflector roll is opened span and is finished from adjustment, adjacent one of one of institute's grinding shaft bearing ring is piled up successively greatly, on the little deflector roll, three blocks of oilstones and oilstone clamping plate are placed on institute and grind above the bearing ring, size by institute's grinding shaft bearing ring external diameter, according to slightly, the lappingout requirement, pass through Pressure gauge, hand-operated valve, adjust cylinder pressure and reach stroke up and down, make the moderate pressure that acts on each bearing ring, then, preceding, mobile support plate in back and cylinder, two of three flexible hold down gags point symmetries are propped up in the centre position of oilstone clamping plate separately, grind to implement external diameter.
Described external diameter grinding machine with the cylinder pressurization is configuration one a cover pressue device on the big deflector roll seat of grinder, its pressue device is made up of cylinder, support plate, flexible hold down gag, pneumatic element case, Pressure gauge, hand-operated valve, wherein three cylinders are fixed on the support plate that can move forward and backward, support plate, pneumatic element case, Pressure gauge, hand-operated valve are installed on the big deflector roll seat, pneumatic element case, Pressure gauge, hand-operated valve connect and control cylinder by pipeline, and the piston rod external part of cylinder and flexible hold down gag link and drive it and do upper and lower mobile.
Described external diameter grinding machine with the cylinder pressurization, its cylinder can be selected the cylinder of guide for use.
Owing to adopted technical scheme as mentioned above, the present invention has following superiority:
1, simplified the complete machine structure of external diameter grinding machine: cylinder has replaced counterweight and support, sled system.
2, reduced processing cost, shortened the production cycle: machined part greatly reduces.
3, adjustment is installed simply, easy for operation: simple in structure, pneumatic operation has alleviated labour intensity.
