Description
Technical field
The utility model relates to a kind of machining equipment, especially leading screw processing cnc lathe.
Background technology
When Workpiece length and diameter ratio during greater than 25 times (L/d＞25), because the rigidity variation of workpiece itself, when turning, workpiece is subjected to the effect of cutting force, self gravitation and rotary centrifugal force, can produce bending, vibration, has a strong impact on its cylindricity and surface roughness, simultaneously, in turning process, workpiece is subjected to the thermal stretching meeting to produce flexural deformation, and turning is difficult to carry out.
Precision lead screw is the important transmission device of precision machine tool, Digit Control Machine Tool and other precision optical machineries and instrument.Convert straight-line accurate gearing to rotatablely moving for playing, the precision of precision lead screw, rigidity, wearability etc. have all been proposed higher requirement.At present, domestic manufacturer's processing ball-screw screw thread raceway adopts the method for " car-quench-roughly grind-finish grind " usually.Stay the allowance of follow-up grinding process during the turning operation, the extension of the heat of workpiece, distortion make follow-up grinding process allowance big during quenching.The common cost of screw grinder equipment that corase grind, precision grinding process are used is higher, and the operation of grinding is consuming time longer, and energy resource consumption is big.
The utility model content
In order to overcome the deficiency that existing leading screw process equipment exists, the utility model provides a kind of novel leading screw processing numerically controlled lathe, the dual-gripper follow-rest mechanism of this leading screw processing cnc lathe configuration high-axiality, in the process of turning, axis servomotor Z2 axle driving follow-rest mechanism follows Z1 axle cutter all the time and is synchronized with the movement, and offsets radial cutting force, strengthens the rigidity of processing work, improve the form accuracy and the surface roughness of processing work, reduced the allowance of subsequent handling.
The technical scheme that its technical problem that solves the utility model adopts is: leading screw processing cnc lathe, critical piece comprises 45 ° of oblique lathe bed parts of postposition, main spindle box part, tail platform and tail platform drive part, slide plate part and saddle running parts, follow-rest part, chip removal part and cooling segment, hydraulic system part, the centralized lubricating system part, the outer guard section of protection and totally-enclosed lathe in Machine Tools Electric part, the lathe.It is that the upper left side of a body has left front cover, there is Zola's door in its outside, there is right sliding door in the outside of right front cover, Z1 axle protective cover is arranged above the bed body of the inside of Zola's door, the below is a Z2 axle protective cover, there is guide supporting left front cover and right front cover below, chip cleaner, there is directing station right sliding door front, there is line slideway auxiliary the top of bed body, saddle is fixed on the slide block of line slideway auxiliary, install slide plate on it, hydraulic pressure cutter tower puts together on the slide plate, and the X-axis servo drive motor is in the back of saddle, Z1 axle servo drive motor is arranged on the left side of bed body, there is follow-rest mechanism bed body front upper place, and the right-hand member of bed body has Z2 axle servo drive motor, and the top left end of bed body has headstock successively, the servomotor of machine tool chief axis, the top right-hand member of bed body has tailstock, and there is a hydraulic system on the back right-hand of bed body.
Leading screw processing cnc lathe, the horizontal distribution form of overall employing, lathe bed adopts 45 ° of rear-inclined lathe bed structures, guide rail is the large scale heavy load Switzerland Shi Naiboge roller line slideway of particular design, have high rigidity and good vibration resistance, each is the high-accuracy rolling guideway to guide rail, improves the lathe response speed greatly, prolongs lathe service life.Main axis transmission system is that AC servo master motor passes through the polywedge bet transmission main shaft, has improved the stationarity of transmission.For realizing the requirement of the tool setting of distinctive dynamic screw thread low speed, high-speed cutting, the main shaft design has the C s function, and cutted thread parted hair function is automatically arranged.
Leading screw processing cnc lathe has disposed the hydraulic pressure follow-rest mechanism that servo Z2 axle drives dual-gripper, and the Z2 axle is selected the ball screw assembly, with the same specification precision of Z1 axle for use, is synchronized with the movement with realization.Follow-rest configuration hydraulic self-centering centre frame, the support when guaranteeing thin and long shafts part turning is accurately reliable.When turner, follow-rest mechanism is synchronized with the movement with Z1 axle cutter all the time, has increased the rigidity of processing work, the distortion when having reduced cutting, thereby improved the form accuracy and the surface roughness of the processing of thin and long shafts parts such as leading screw, guaranteed thin and long shafts part processing steadily.The use of follow-rest can strengthen cutting data, has reduced the allowance of follow-up grinding process, has changed traditional ball-screw processing technology, thereby has enhanced productivity, and reduces production costs.
The beneficial effects of the utility model are that the hydraulic pressure follow-rest mechanism of configuration dual-gripper realizes that follow-rest and cutter are synchronized with the movement, and strengthens the workpiece rigidity, improves the form accuracy and the surface roughness of thin and long shafts part processing such as leading screw, enhances productivity.The main shaft design has the C s function, and cutted thread parted hair function is automatically arranged, and realizes the function of distinctive dynamic low speed tool setting high-speed cutting.
