Description
Technical field the utility model relates to a kind of surface press finishing mechanism of shaft-like workpiece.
Background technology tumbling processing is a kind of very effective processing mode that improves workpiece accuracy, and adopt machined into substantially for the tumbling of shaft-like workpiece at present, for example machined into is adopted in the tumbling of air throttle of car axle, and install on this lathe one the tumbling cutter in the process of processing, axle is one-sided stressed, cause the axiality of axle to worsen after the tumbling, and have the possibility of fracture; In addition, the roughness and the external diameter of Zhou the feed and the position of returning sword are inconsistent.This processing mode only is applicable to the axle that external diameter is bigger, can not adopt the processing of this sample loading mode for external diameter less than the axle of Φ 20.
For the less axle of external diameter, present roll extrusion mode adopts dark roll extrusion cutter processing, this processing action also is to finish on lathe, the structure of dark roll extrusion cutter is that columnar cutter box inside is provided with three equally distributed tumbling cuttves, be positioned at the inside of three tumbling cuttves during work, along with the rotation of axle, the cutter axial rotation, in tool motion, tumbling is carried out on the surface of axle.Though it is one-sided stressed and avoid the axiality of axle to worsen that this mode has solved axle, weak point is:
1, the roughness and the external diameter of Zhou the feed and the position of returning sword are inconsistent.
2, owing to be machined into, after the end tumbling of axle, during the tumbling other end the tumbling end easily damaged by the lathe chuck.
3, the wearing and tearing to cutter are big, increase production cost.
4, working (machining) efficiency is low, increases labour intensity.
The summary of the invention the purpose of this utility model is to provide a kind of machining accuracy height, and labour intensity is low, and production cost is little, working (machining) efficiency height, the axle class surface high accuracy rolling mechanism of good product quality.
The utility model comprises roll extrusion assembly and hydraulic package.
The roll extrusion assembly mainly comprises two corresponding rollers, and described roller housing is connected in the rotating shaft, and the two ends of rotating shaft are provided with bearing block, the bearing block of one of them roller both sides with decide piece and be connected, the bearing block of another roller both sides is connected with slide block.
Hydraulic package mainly comprises fuel tank, oil pump, motor, solenoid directional control valve, one-way throttle valve and oil cylinder, described fuel tank, oil pump, motor, solenoid directional control valve and one-way throttle valve are same as the prior art substantially, on the driving shaft of motor, connect oil pump, the inlet port of oil pump links to each other with fuel tank, for preventing that oil pump dirt when the oil suction from entering and prolonging the service life of oil pump, oil absorbing end at oil pump is installed the oil suction oil filter, the oil-out of above-mentioned oil pump links to each other with the oil-in of solenoid directional control valve by pipeline, constant for guaranteeing the oil pump outlet pressure, on the oil-out of oil pump, be provided with high-pressure overflow valve, the oil returning tube of this high-pressure overflow valve links to each other with fuel tank, and is provided with check valve on the pipeline between oil pump and the solenoid directional control valve.Above-mentioned solenoid directional control valve is provided with two outlets, outlet one links to each other with the oil-in in the feeding chamber of oil cylinder, outlet two links to each other with the oil-in of returning the chamber of oil cylinder, on the outlet one of solenoid directional control valve and the pipeline between the oil cylinder, be provided with one-way throttle valve, and on one-way throttle valve, be provided with oil returning tube, this pipeline links to each other with Hydraulic Station, and Hydraulic Station links to each other with fuel tank by pipeline; On the outlet two of solenoid directional control valve and the pipeline between the oil cylinder, be provided with low pressure relief valve, and the oil returning tube of low pressure relief valve links to each other with fuel tank.Connect guide rod on the piston of above-mentioned oil cylinder, this guide rod links to each other with slide block in the roll extrusion assembly.
Processing mode of the present utility model mainly is to utilize the compressing of two pair of rollers surface of the works, and when the extruding of roller surpassed the yield strength of surface of the work, plastic deformation had just taken place marginal layer, thereby reaches the purpose to the surface of the work tumbling.
The utility model is work like this:
The utility model is installed on the lathe in use, and two rollers promptly connect worm screw by the direct driven rotary of motor on shaft of motor, and the main shaft of roller inside is connected with worm screw by gear, and then two rollers rotate in rotating shaft in the same way.Workpiece (axle) is placed between two rollers, this moment the primer fluid pressing system motor, the work of driven by motor oil pump, oil in the oil sump enters solenoid directional control valve, oil is through exporting a feeding chamber that enters oil cylinder, the piston feeding, the drive slide block moves, the roller that is connected with slide block moves, roller moves to apart from workpiece certain position place, this position is provided with contact switch, contact switch connects photoelectric sensor, contact switch and photoelectric sensor operated by rotary motion are on lathe, photoelectric sensor sends signal, and then the choke valve of Hydraulic Station is started working, and the feed speed of piston is slack-off, the feed speed of roller is slack-off thereupon, and the operating pressure of roller increases, and this moment, roller touched workpiece (axle), and the working time of choke valve is controlled by the time relay, after choke valve quits work, the operating pressure of roller continues to keep, and the roller feed-disabling, and this dead time is also controlled by the time relay, after arriving the pre-set dead time, the outlet one of solenoid directional control valve is closed, and oil enters the chamber of returning of oil cylinder through the outlet two of solenoid directional control valve, and piston returns, slide block drives roller and returns, and processes at one time.With after workpiece contacts,, then drive workpiece (axle) rotation at roller because two rollers itself rotate in the same way, and workpiece is installed on the carriage that can move up and down on the lathe, then adding man-hour, each position on workpiece (axle) surface all can contact roller, keeps the external diameter unanimity.
The utility model compared with prior art has following advantage: improve machining accuracy, reduce labour intensity, reduce production cost, working (machining) efficiency height, good product quality.
