Description
Technical field
The utility model relates to the abrasive machine technical field, is the two-way belt grinding machine of a kind of dual-gripper specifically.This machine is applied to oil field sucker rod polished rod grinding.
Background technology
The sucker rod polished rod is applied in the oilfield oil pumper well head, and polished rod plays piston rod.Excircle dimension precision and roughness require high.The equipment for grinding model of original sucker rod polished rod is: 2M5140.Title: cylindrical abrasive band polishing lathe; Structural shape is that belt grinding machine is that single head, rod structure are cantilever single support type formula (accompanying drawing 1).The principle of this equipment for grinding is: the abrasive band is enclosed within respectively on driving wheel, follower, follower, the regulating wheel cylindrical, through the driving wheel rotation, drives the abrasive band with certain tension force and moves around above-mentioned rod.The sucker rod polished rod is being rotated by direction shown in the accompanying drawing 1 by feeder and is promoting simultaneously, and this moment, the slewing maneuver handwheel made planker pass through leading screw, approaching, the grinding polished rod in mother lead screw drive milling drum abrasive band.Wherein the effect of follower is to increase the friction cornerite of abrasive band on driving wheel, and changes the abrasive band movement locus.
The shortcoming of this equipment for grinding is:
1): the single head grinding makes work piece centering unstable, adds workpiece existence vibrations in man-hour and cutter relieving phenomenon.
2): when grinding roller cantilever list was supported on the grinding work piece, the abrasive band usually broke away from roller.
3): the roller bearing rapid wear; Because of the contact-making surface of abrasive band and follower is the grinding face in abrasive band, follower is by the serious rapid wear of grinding, and life cycle is short.
4): grinding efficiency is low.
5):, add workpiece existence vibrations in man-hour and cutter relieving phenomenon because work piece centering is unstable.
After the grinding, excircle of workpiece has spiral lamination.
Summary of the invention
The purpose of the utility model provides the two-way belt grinding machine of a kind of dual-gripper, in order to solve the defective of above-mentioned prior art.
The technical scheme of the utility model be the two-way belt grinding machine of dual-gripper by grinding feed handwheel, protective cover, gripper shoe, work piece, follower, driving wheel, regulating wheel, alignment pin, abrasive band, regulating wheel operator link, support, leading screw and mother lead screw, belt pulley, planker, ram is formed;
The abrasive band is contained in by on the kinematic pair of forming on driving wheel, follower, the regulating wheel three roller cylindricals; The two roller axle left ends that are equipped with driving wheel, follower are contained in respectively on the support, and two roller axle right-hand members of driving wheel, follower are installed on the gripper shoe, and gripper shoe is through alignment pin and be bolted to regulating wheel and install on the block; The regulating wheel that regulating wheel is fixed on the support is installed on the block, and regulating wheel is installed block and is fixed on the support; Install in the hole on the block spring is housed, initial tension of spring promotes regulating wheel; Belt pulley is installed in the drive sprocket axle left end; Support is fixed on the planker; The regulating wheel operator link is installed on the tension wheel shaft left end; Grinding feeds handwheel and is connected with left-right turning screw rod, and left-right turning screw rod is installed on the ram, about two mother lead screws are installed in respectively on two plankers.
The utility model adopts the two-shipper head in design, at first utilize left-right turning screw rod, mother lead screw, realizes that the abrasive band is to advancing (grinding feeds) and splitting (withdrawing); Out-of-balance force when the bi-directional symmetrical grinding can have been eliminated former type grinding like this, thus realize the basic demand of steady grinding.In addition; Cancelled the follower in the former organic type; With the diameter increase of regulating wheel and with moving on its position, can guarantee the friction cornerite of abrasive band on driving wheel like this, utilize regulating wheel that block is installed again and be benchmark; Driving wheel, the right gripper shoe of follower are put together on regulating wheel and install on the block, locate with the circular cone pin.Basic demand is achieved one by one like this.
The utility model has the advantages that and adopt the double end grinding to make work piece centering stable, add the man-hour workpiece and be in relative equilibrium grinding force and relatively effective grinding state all the time.Thereby make workpiece centering stable, add workpiece vibrations in man-hour and cutter relieving phenomenon and do not existed, realize continuous grinding.Eliminated the spiral lamination that former machine exists at excircle of workpiece because of intermittent grinding.
The dual-gripper of grinding roller is when the grinding work piece, and three rod axle center remain parastate, adds the rod configuration design again and becomes little drum type, makes abrasive band work remain on optimum condition.The parallel unanimity that remains in roller axle center, thereby good work running environment is provided for bearing.The life-span of roller bearing improves greatly, has reduced maintenance frequency, has effectively increased the working time; Improve grinding efficiency, improved grinding accuracy.
