Description
Technical field
The utility model belongs to the Metal Cutting Machine Tool technical field, and particularly electric main shaft is in the design of not being in the mood for application on the lathe and cylindrical bar, pipe material automatic centering equipment.
Background technology
Be not in the mood for the outer round surface processing that lathe is mainly used in cylindrical bar, pipe material, so that remove cementation zone, crackle and other defective, and then improve cylindrical bar, pipe material quality, than routine on general horizontal lathe, increase the processing mode of centre frame supplemental support cylindrical bar, pipe material, efficient increases substantially, and therefore is subjected to user's welcome.
The traditional structure of not being in the mood for lathe and workflow are as shown in Figure 1, cylindrical bar, the pipe material at first enters the input clamping delivery mechanism, cylindrical bar, the pipe material is through roller 101 location and the driving of one or more groups rotation, do feed motion along straight line, roller 101 drives by variable-frequency motor and through chain or universal drive shaft, realize corresponding rotatablely moving, simultaneously, be installed in roller clamp cylinders shape rod radially on the top shoe by hydraulic-driven, the pipe material, its centering is adopted the rack-and-pinion mode usually, promptly move down by hydraulically powered top shoe, the upper roller that is installed on the top shoe moves downward, the tooth bar that is installed in the top shoe side moves downward, driving is the gear rotation at center with the central shaft with the tooth bar engagement, the tooth bar that drives the other end and gears engaged moves up, the tooth bar that is installed in the sliding block side moves upward, the bottom roller that drive is installed on the sliding block moves upward, thereby realization cylindrical bar, tight and the centering of pipe feed collet, the fixed bit of the rear and front end of central shaft are to realize by adjustment and the trip bolt adjusted on the two end supports plate.Cylindrical bar, pipe material enter just and are held behind the location structure 102.When cylindrical bar, pipe material enter cutting region, cylindrical bar, pipe material that 103 pairs on the cutter of rotation is done the straight-line feed motion carry out machining, the cutter 103 of rotation is by one or manyly cutting tool is formed and be contained on the cutterhead, cutterhead is installed on main shaft 104 end faces, main shaft 104 is installed in the bearing 106, bearing 106 is installed on the pedestal 105 of cutting mechanism, main shaft 104 is by variable-frequency motor, drive to through gear or cog belt that gear or profile of tooth belt wheel 111 drive, main shaft is connected by axis hole interference fit and flat key with gear or profile of tooth belt wheel.In cylindrical bar, the pipe material of cutting entered grip device 107 in the main shaft endoporus, grip device 107 was installed on pedestal 105 end faces of cutting mechanism and stretches in the main shaft endoporus.The finished product grip device has center hole, and grips through the workpiece of cutting by brake pad or the pair of rollers that is installed in pitch circles such as in this mechanism many groups, thereby improves the precision and the surface roughness of workpiece to be machined; Leave gap 112 between main shaft endoporus and main shaft tail end face and the finished product grip device 107.Then, expect to enter the output clamping delivery mechanism through cylindrical bar, the pipe of cutting, the structure of output clamping delivery mechanism is identical with the input clamping delivery mechanism with workflow.Cylindrical bar, pipe material through cutting are derived by the output clamping delivery mechanism.Said mechanism is installed on the lathe bed 109.Be not in the mood for lathe and also comprise electric-control system, lubricating system, cooling and chip removal system, blank and product storage system etc.
Use more and more extensivelyr along with not being in the mood for lathe, tradition is not in the mood for the problem that lathe exists and is displayed gradually yet.
Based on not being in the mood for the lathe structure characteristics, need the finished product holding mechanism in its main shaft, one or more groups control is radially in its main cutting system, axially the bearing of precision and cutting force can only be selected larger-diameter bearing for use.Be not in the mood for lathe when the workpiece of cutting minor diameter, want to keep cutting quality, just must select rational cutting linear velocity, guarantee rational cutting linear velocity, just must improve the speed of mainshaft, the linear velocity of bearing portion wants several times even number to decuple the linear velocity at workpiece cutting position, this just causes the damage of bearing easily, both increased cost and change bearing, very bothersome again, influence production efficiency, even if even improved the speed of mainshaft sometimes, can not reach the cutting linear velocity that can guarantee crudy.Be to reduce the damage of bearing, many users reduce rotating speed usually, have consequently not only reduced efficient but also have influenced the crudy of workpiece.Renewal along with technological progress and people's management philosophy, production and the specification requirement of not being in the mood for the lathe user are more and more higher, the allowance that the workpiece blank external diameter leaves is more and more littler, traditional mode centering of not being in the mood for machined into cylindrical bar, pipe material employing rack-and-pinion, owing to adopt the rack-and-pinion mode must leave the gap, and the effect tooth bar owing to pressure angle when the engagement of stressed big situation lower tooth portion is outwards pushed, the central shaft two ends are unsettled fixing by screw, vibration is bigger in turning process in addition, and it is steady to be difficult to clamping; Therefore precision is not enough, occurs the chipping allowance skewness easily, causes hardened layer, crackle and the defective etc. on some surface, position not to remove, and has influenced workpiece quality.
