Description
Technical field
The present invention relates to a kind of clamping device of oilstone, especially relate to a kind of taper roll bearing superfinishing oil stone automatic clamping device.
Background technology
Superfinishing, be called for short " microstoning ", generally refer under good lubricating condition, workpiece to be machined rotates by certain speed, oilstone is pressed on workpiece machining surface by certain compressive resilience, and is making a kind of polishing processing method that can automatically complete of reciprocating vibration motion according to certain rules perpendicular to workpiece direction of rotation.
The whole process of superfinishing comprises 3 stages: finishing, constant cut, polishing also have and be divided into: cutting stage or from the sharp stage, partly cut stage, polishing stage.And whole process is at basic technological parameters as work speed, and oilstone pressure, completes under oilstone frequency of oscillation and the constant condition such as amplitude and metalworking coolant automatically.
1, the advantage of superfinishing
1. circular deviation can effectively be reduced;
2. effectively can improve the linearity of raceway cross section or be processed into required protuberance shape;
3. can remove grinding skin, reduce surface roughness value;
4. surface can be made to have remaining compression;
5. the lines of texture uniform and smooth can be formed at finished surface;
6. functional contact bearing area can be made to increase.
2, microstoning is on the impact of rolling bearing service behaviour
1. improve the running accuracy of bearing, reduce the vibration & noise of bearing
2. the bearing capacity of bearing is improved;
3. improve the lubricant effect of bearing, reduce wearing and tearing;
In rolling bearing processing, superfinishing equipment is the last key equipment in operation, finally determines precision and the performance of bearing completed products.In the superfinishing process of rolling bearing lasso, required precision is very high, traditional manually tightens the needs that screw in compression superfinishing oilstone mechanism can not meet taper roll bearing superfinishing, so surpass in fining equipment at novel tapered roller bearing, must adopt automatic abrasive stick clamp system.
Summary of the invention
The troublesome poeration, inefficiency and the clamping degree that the object of the invention is to cause for solving superfinishing oilstone is bolted in prior art clamping mode control the problem of inconvenience, provide a kind of taper roll bearing superfinishing oil stone automatic clamping device.
The present invention is the deficiency solved the problems of the technologies described above, and the technical scheme adopted is:
A kind of taper roll bearing superfinishing oil stone automatic clamping device, comprise superfinishing oil stone clip, one end of superfinishing oil stone clip offers the oil duct be communicated with oil supply system, the other end of superfinishing oil stone clip offers reducing hole, reducing hole is divided into oilhole section successively, working hole section and stepped hole section, one end of oilhole section is communicated with oil duct, the diameter that stepped hole section diameter is less than working hole section establishes so that form card the step installing superfinishing oilstone to be clamped, the clamp system for being pressed on by superfinishing oilstone to be clamped on step is provided with in working hole section, described clamp system comprises oilstone briquetting, connecting pin, end cover, back-moving spring and piston, end cover is fixed on oilhole section and forms an oil cylinder away from one end of oil duct making oilhole section, piston to be slidably arranged in oilhole section and the external part of piston through end cover, oilstone briquetting is pressed on superfinishing oilstone to be clamped, and oilstone briquetting to be connected on the external part of piston by connecting pin so that pressure oil promotes piston and slides to drive oilstone briquetting to compress superfinishing oilstone to be clamped when passing into pressure oil in oil duct, also back-moving spring is provided with so that pressure oil is resetted by back-moving spring driven plunger with the taking-up realizing superfinishing oilstone to be clamped after taking away in oil duct between end cover and piston.
The diameter of described working hole section is greater than the diameter of oilhole section.
The invention has the beneficial effects as follows: 1, the present invention change traditional clamping mode by pressure oil control clamping can realize automated exchanged cutter superfinishing oilstone, without the need to manual compression, significantly improve working (machining) efficiency.2, by arranging the hydraulic throttle valve of oil supply system, setting hydraulic flow can realize automatically setting oilstone clamp speeds, improves working (machining) efficiency and does not damage oilstone.3, simultaneously by arranging the hydraulic relief valve of oil supply system, by setting hydraulic pressure, can realize automatically setting oilstone clamping strength, reliable grip oilstone, improves working (machining) efficiency and does not damage oilstone.4, the loading and unloading oils cubic meter of stone of the present invention just, is convenient to realize automated production, can be applied to taper roll bearing superfinishing field.
