Abstract
The utility model relates to a bearing inner and outer ring superfine grinding hone fluid pressurizing control device, which is characterized in that shuttle valves (3) which are positioned on the back parts of pressure reducing valves (2) and the front parts of working cylinders are used for replacing two-position three-way change valves (1) in a system; both sides of the shuttle valves are respectively connected with two pressure reducing valves by pipes (4). The shuttle valves are used for the conversion of the super thick and superfine pressure, matching with the communication and broken of the change valves in the system after that the pressure is reduced by the pressure reducing valves to choose fluid in one passage with large pressure. The fluid flows into a working cylinder of the next section after selected by the shuttle valves. The utility model realizes the standardisation of elements, reduces the insecure factors and solves the problems of stabilizing adjustment of system pressure.
Description
Technical field:
The utility model relates to technical field of bearing processing, a kind of bearing enclose fine abrasive oilstone pressurized with fluid control device.
Background technology:
In precision bearing manufacturing process, bearing enclose raceway fine abrasive is the final processing of precision bearing lasso processing, and its purpose is to improve the dimensional accuracy and the surface roughness of lasso raceway face circle, final precision and service life of realizing improving bearing.The microstoning process of this raceway takes single head or double end slightly surpasses and essence surpasses two work step processing modes, and wherein the thick pressure super, that essence is super of control will be adjusted respectively.Control commonly used is slightly super, the control mode of smart over pressure fluid as shown in Figure 1, be connected by pipeline with two pressure-reducing valves by two position three way directional control valve, the designing requirement pressure-reducing valve should be as much as possible near controlled element, the middle transitional element, especially there is the element of leakage few more good more, the back of pressure-reducing valve in the prior art, the two-bit triplet reversal valve of working cylinder front is non-standard valve, buy and install all inconvenient, and the leakage of this guiding valve itself, it is not very stable making its operating pressure, is unfavorable for system's reliability service.
Summary of the invention:
In order to overcome the deficiencies in the prior art, the purpose of this utility model provides a kind of bearing enclose fine abrasive oilstone pressurized with fluid control device, carries out conversion slightly super, smart over pressure, has realized the element standardization, reduce unreliable factor, solved the stable problem of adjusting of system pressure.
To achieve these goals, the utility model adopts following technical scheme:
This bearing enclose fine abrasive oilstone pressurized with fluid control device, back at pressure-reducing valve, the front of working cylinder is by the two-bit triplet reversal valve in the shuttle valve alternative system, both sides at shuttle valve connect two pressure-reducing valves by pipeline respectively, the reversal valve break-make is carried out conversion slightly super, the smart pressure that surpasses in the use shuttle valve coupled system, that road pressure is big, just selects the fluid on that road; The fluid of system is selected through shuttle valve after reducing pressure by pressure-reducing valve, enters in the working cylinder of next link.
Owing to adopted technical scheme as mentioned above, the utlity model has following good effect:
This bearing enclose fine abrasive oilstone pressurized with fluid control device is selected for use simply, meets domestic and international standard, and is easy for installation, and the pressure adjustment is stable, helps system's reliability service.
The drawing explanation:
Fig. 1 is the existing pneumatic control principle of a pressurized with fluid control device sketch:
Fig. 2 is the utility model pneumatic control principle sketch:
As shown in Fig. 1, Fig. 2: 1-two-bit triplet reversal valve, 2-pressure-reducing valve, 3-shuttle valve, 4-pipeline.
The specific embodiment:
This bearing enclose fine abrasive oilstone pressurized with fluid control device, back in pressure-reducing valve (2), the front of working cylinder is by the two-bit triplet reversal valve (1) in shuttle valve (3) alternative system, both sides at shuttle valve connect two pressure-reducing valves by pipeline (4) respectively, the reversal valve break-make is carried out conversion slightly super, the smart pressure that surpasses in the use shuttle valve coupled system, which pressure is big, just selects which fluid; The fluid of system is selected through shuttle valve after reducing pressure by pressure-reducing valve, enters in the working cylinder of next link.
Claims (1)
1, a kind of bearing enclose fine abrasive oilstone pressurized with fluid control device, it is characterized in that: back in pressure-reducing valve (2), the front of working cylinder connects two pressure-reducing valves by pipeline (4) by the two-bit triplet reversal valve (1) in shuttle valve (3) alternative system respectively on the both sides of shuttle valve.
