Description
Technical field
The utility model relates to grinding machine parts, specifically, relates to a kind of clamping device for grinding machine and a kind of multifunctional grinder, belongs to machining technique field.
Background technology
Grinding technique and grinding machine occupy extremely important position in machinery manufacturing industry, and grinding technique development is very fast, plays extremely important effect in machining.Along with the increase of high accuracy, high rigidity machine components quantity, and the development of hot investment casting and precision forging technology, the performance of grinding machine, kind and output are all constantly improving and are increasing.Grinding machine is the class that in all kinds of metal cutting basis, kind is maximum, and main Types has cylindrical grinder, internal grinder, surface grinding machine, centerless grinder, cutter and tool grinding machine etc.The development trend of current plain grinding turns to shaping, step, incision, fast jitter, the processing of three-dimensional space curve surfacing, and numerically control grinder is an importance of grinding machine development, and numerical control can realize automation, the high efficiency of lathe work better.
Numerically control grinder can be used for the inside and outside face of cylinder of grinding, taper seat, plane, helicoid, spline, gear, guide rail, cutter and various forming faces etc.Divide according to the process applications of grinding machine and have numerical control external cylindrical grinding machine, numeral-controlled internal grinder, digital control plain surface grinding machine, numerical control tool grinder, CNC jig grinding machine, grinding center etc.
Numerically control grinder generally comprises base unit, auxiliary unit and digital control system, and digital control system controls base unit and auxiliary unit.Base unit comprises base, grinding head device, workbench, lathe bed, planker, column etc., and its design and manufacturing technology is the basic of guarantee grinding machine quality; Auxiliary unit comprises quick clamping device, cutting fluid feed system, security protection process etc.
Workpiece, in process, by the relative distance of workpiece on adjusting operating platform and grinding head device, determines processing.And regulating the relative distance of workpiece and grinding head device to have two kinds of modes: one mainly relies on worktable lifting, and workbench is lifting structure, and clamping workpiece on the table, regulates the relative distance of workpiece and grinding head device by the height adjusting workbench; Another kind mainly relies on grinding head device to be elevated, and grinding head device is regulated along the column guide rail on column by elevating mechanism, regulated the relative distance of workpiece and grinding head device by the height adjusting grinding head device.These two kinds of modes can regulate the relative distance of workpiece and grinding head device, but the first utilizes the mode of worktable lifting not to be suitable for large-scale workpiece, large-scale workpiece is too heavy, workbench drives workpiece lifting loss too large, waste energy, shorten the service life of grinding machine, the mode adopting grinding head device to coordinate along the column guide rail on column and with elevating mechanism that therefore gets more and more now to adjust the height of grinding head device, thus regulates the relative distance of workpiece and grinding head device simultaneously.
Grinding head device comprises bistrique and planker, and bistrique is arranged on column by planker, controls planker and bistrique and moves along the column guide rail of column, the distance between adjustment grinding head device and workpiece by elevating mechanism.When bistrique is in machining state in grinding head device, between column with planker, need relative fixing; When grinding head device lifting moving, need between column and planker to leave gap, planker is slided on column smooth and easy.But be difficult between planker and column guide rail keep reasonable clearance, gap between usual planker and column guide rail can be excessive, can produce when grinding head device works like this and have a strong impact on: 1, the rigidity of column, column guide rail and planker can not play, cause the coupling stiffness between three poor; 2, the gap play between the concentricity of bistrique and main shaft causes work pieces process to have curl; 3, grinding head device is without firm support, and grinding head device medium plain emery wheel may be sagging, causes work pieces process qualification rate to reduce; 4, bistrique unbalance stress in grinding process in grinding head device, may there is falling cutter phenomenon in serious, affect personal safety.Therefore need to adjust the gap between grinding head device middle carriage and column guide rail, make the gap between planker and column guide rail reasonable.
Several adjustment mode is proposed for the gap adjustment between planker and column guide rail in prior art, but all there is various problem: 1, the guide rail gap regulation mechanism that a kind of borer rail clearance adjustment mechanism that CN 2012206102503 provides proposes, this guide rail gap regulation mechanism employing horizontal adjusting bolt coordinates with horizontal adjustment block and forms horizontal clearance guiding mechanism, perpendicular bolt coordinates with vertical adjustment block and forms down suction guiding mechanism, by horizontal clearance guiding mechanism adjustment horizontal clearance, guiding mechanism adjustment down suction, down suction, but this kind of adjustment mode is in course of adjustment completely according to bolt-locking, very accurately can not control the deep length of bolt, also just can not very accurate control gap, the prerequisite realizing this kind of regulative mode is in addition that the perpendicularity of guide rail is very accurate, if guide rail produces distortion, then gap is by bad control, 2, space of slider guiding mechanism in the slider of hydraulic press track-type facilities that CN 2012203464358 provides, this space of slider guiding mechanism comprises slide block front and back end clearance adjustment mechanism and slide block gap between two ends guiding mechanism, slide block front and back end clearance adjustment mechanism passes through block, first adjustment screw, the gap of the first lock-screw and adjusting nut adjustment slide block front and back end and guide rail, slide block gap between two ends guiding mechanism passes through copper guide plate, guide plate, wedge, the gap of the second adjustment screw and the second lock-screw adjustment slide block two ends and guide rail, but space of slider guiding mechanism is still adopt screw control gap, the length deep due to bolt is wayward, the size in gap also not easily accurately controls, 3, the hydrostatic slideway with horizontal clearance feedback device that provides of CN 2012205701911, piston apparatus structure regulating static guide rail horizontal clearance is adopted in this device, prevent hydrostatic slideway stuck, and the life-span that this kind of mode adopts piston apparatus structure to regulate is limited eventually, when the end-of-life of piston apparatus, whole hydrostatic slideway also can not use.In addition, the guiding mechanism in gap between the planker proposed in prior art and guide rail, when guide rail occurs various distortion because of long-time use, according to the deformation-compensated of guide rail or can not adjust this gap.
Therefore, need a kind of clamping device badly to make to retain reasonable clearance between grinding head device and column, grinding head device slides smooth and easy on column, ensures machining accuracy simultaneously, improve the coupling stiffness between column and grinding head device, and can according to guide rail distortion or machining accuracy adjusting play at any time.
