Background technology

Automobile needs often to change travel direction in the process of moving, promptly turns to.Steering gear is that the turning moment with steering wheel is transformed into swing offset, and power is passed to the mechanism that wheel makes motor turning; Rack and pinion power steering then is to realize this conversion by the gear motion between wheel and rack, this type of power steering stgear provides the part power-assisted to help the driver by hydraulic oil in steering procedure and realizes turning to, and the valve pocket on the power steering stgear is exactly the valve that the fluid path is provided for steering gear.---heat treatment---fine finishining---polishing that the production process of rack and pinion power steering valve pocket is: roughing; Wherein polishing process is a very important operation, the quality problems of many valve pockets are exactly because the cylindrical polishing is not thorough, cause the caducous oxide in place, right angle effectively not remove, produce that a large amount of foreign matters and impurity causes, bring very big influence for the total quality of spool.The present step of polishing of valve pocket is on engine lathe on the other hand, adopt waterproof abrasive cloth to be cut into the emery cloth strip of 2mm width, manual do on the valve pocket cylindrical that tangential straight-line feed motion finishes, this method of operation in operation person must be with protective helmet and mouth mask, prevent the hone liquid and the foreign matter that splash, so not only can not guarantee crudy, and bring very big influence for the working environment of periphery.

Summary of the invention

The purpose of this utility model is: provide a kind of by being arranged on the power transmission shaft termination, and by the polishing cutter of driven by motor rotation, contact with the core member surface of rotation and produce cutting, thereby reach the purpose of polishing the core member cylindrical; To solve existing core member because the cylindrical polishing is not thorough, the caducous oxide in place, right angle can not effectively be removed, and causes producing a large amount of foreign matters and impurity, brings the feasible multistage step cylindrical polishing machine of convenience of influence for the total quality of spool.

The utility model is to realize above-mentioned purpose by the following technical solutions:

The multistage step cylindrical polishing machine that a kind of convenience is feasible, it is made of lathe bed, headstock, guide rail, saddle, upper slide rest, tailstock, scroll chuck; Be manufactured with guide rail on the lathe bed, one end of lathe bed is equipped with headstock, scroll chuck is housed on the headstock, saddle is installed on the guide rail of lathe bed, saddle is connected with headstock by drive lead screw, saddle top is provided with upper slide rest, and the guide rail of the lathe bed other end is provided with tailstock, it is characterized in that: buff spindle is housed on the scroll chuck; Cylinder anchor clamps and cylinder switch are housed on the tailstock; Upper slide rest is provided with motor, front end one side of motor is equipped with power transmission shaft by mount pad, and power transmission shaft one end is provided with the polishing disk of band wire brush, and polishing disk is provided with protective cover, the power transmission shaft other end is provided with belt pulley, and belt pulley is connected with motor by driving-belt.

The beneficial effects of the utility model are:

This multistage step cylindrical polishing machine is when polishing operation, and core member is rotated under the drive of buff spindle, and and the rotation of polishing disk combine and produce cutting, thereby reach the purpose that makes the workpiece polishing.The not subsidiary hone liquid of this polishing machine can effectively change operating environment, and can effectively remove the oxide at place, product right angle.Avoided existing core member because the cylindrical polishing is not thorough, the caducous oxide in place, right angle can not effectively be removed, and causes producing a large amount of foreign matters and impurity, all brings the problem of very big influence for the total quality of core member and the working environment of periphery.This polishing machine replaces existing manually polishing by motor-driven polishing disk, has improved operating efficiency, has alleviated labour intensity, has guaranteed crudy, and is convenient to operation; Dispose the special protection cover on the polishing disk, guaranteed operating personnel's production safety, be specially adapted to the core member polishing and use.
