Description
Technical field
The present invention relates to a kind of drilling bit grinding clamping device, in particular, relate to abrasive flows medium that a kind of utilization has certain pressure and a flow velocity carries out extrusion honing clamping device to drill bit.
Background technology
Drill bit is for drilling place through hole or blind hole on solid material, and can to the cutter of existing hole reaming.Conventional drill bit mainly contains fluted drill, chit drill, centre drill, depth drill and cylindrical drill.
Extrusion honing technology, also known as abrasive Flow Machining technology, is a kind of surface finish in modern age and the new technology of deburring, has good effect to the polishing of mould and part and deburring.Extrusion honing is a kind of polishing method utilizing the abrasive Flow medium (viscosity abrasive material) with certain pressure and flow velocity to carry out honing, be mainly used to improve some endoporus, the crudy of bending aperture, cross facet, cross bore and irregular different in nature surfaces externally and internally, less surface roughness Ra value, remove the damaged surface layer of spark machined, hidden part burr, to seamed edge rounding etc.
Existing drill bit extrusion honing apparatus system generally comprises four elements: clamping device, hydraulic power unit, secondary hydraulic system, control loop, auxiliary equipment and control system; Clamping device adopts snail sample spiral top treasure clamping device, and it is by friction clutch transmission, can adjust and control the clamping force of fixture, when the extruding force that fixture inside is subject to processing, can effectively prevent clamp fixing plate from unclamping; Hydraulic power unit is the hydraulic power source producing pressure needed for extrusion head, and promote abradant fluid medium and make it by workpiece, hydraulic power unit will prevent hydraulic pressure to fluctuate, general employing flow adjustable constant voltage pump and control valve device; Secondary hydraulic system is used for rollback or the calibration of fixture, and abradant fluid medium is supplied to processing district, or carries out other any clamp operation of special fixtures; Control system be used for the pressure of hydraulic control system, the flow velocity of abradant fluid medium, the clamping of workpiece and unclamp, the reciprocating motion of grinding chamber piston and complete according to program automatic cycle etc.; Control loop is the automatic cycle programming production process being manually difficult to be competent at being carried out to installment and debugging; Auxiliary equipment comprises cooling processing district, dielectric film filter case and separator etc.
Therefore, reducing under bit face roughness, restriction working (machining) efficiency and the prerequisite of improving the quality of products, using extrusion honing technology to process drill bit, can realize completely thoroughly removing burr, thus improving surface quality, extend part service life; Adopt extrusion honing method not only efficiency is high simultaneously, and can improve the roughness of hole wall, cross bore is modified as certain rounding off in the place of passing through mutually simultaneously.
Summary of the invention
The object of the invention is to solve that bit face roughness is higher, drill bit adds the slow and problem that bit face is of low quality of working (machining) efficiency in man-hour, provide a kind of reduction bit face roughness, and the surface quality of drill bit can be increased substantially, and the drill bit extrusion honing device of working (machining) efficiency and crudy can be improved largely.
The present invention is achieved through the following technical solutions above-mentioned purpose: a kind of drill bit extrusion honing device, comprise housing, upper clamping, lower clamping and two abrasive material transition discs, described upper clamping is contained in the top of described lower clamping, two abrasive material transition discs are installed in the outside of upper clamping and lower clamping respectively, and described two abrasive material transition discs by straight pin two abrasive materials are crossed scale and upper clamping, lower clamping are fixed as one; The clamping groove of the caudal peduncle for clamping drill bit to be processed is provided with between described upper clamping and lower clamping, the through hole for abradant fluid medium circulation scale, upper clamping and lower clamping being also provided with and running through up and down crossed by described two abrasive materials, and the import and export two ends of through hole connect upper end squeeze cylinder and lower end squeeze cylinder respectively; The head of drill bit to be processed stretches out clamping and lower clamping and extend in described through hole; Described housing is sleeved on the outside of two abrasive material transition discs.
Further, be provided with for the clamping groove of the caudal peduncle of clamping drill bit to be processed between upper clamping and lower clamping at least three right.The quantity of clamping groove can control according to actual needs, meets the object that multiple drill bit to be processed is processed simultaneously.
Further, bottom described upper clamping and lower clamping top is respectively equipped with projection for upper clamping and lower Set and Positioning and groove.Being realized the location of upper clamping and lower clamping by protruding and groove, can not there is mutual slip in the position of both guarantees.
Further, the left and right sides that described two abrasive materials cross scale, upper clamping and lower clamping is provided with the symmetrical and pin-and-hole of position consistency, and two abrasive materials are crossed scale, upper clamping and lower clamping through pin shaft hole and are fixed as one by straight pin.
The outside that housing is sleeved on two abrasive material transition discs prevents the abradant fluid medium in through hole from flowing to device outside.Abradant fluid medium by the clamping groove that adds drill bit to be processed and be pressed in upper clamping and lower clamping, and to be circulated conveying by upper end squeeze cylinder and lower end squeeze cylinder by a kind of drill bit extrusion honing device of the present invention in through-holes back and forth; When the piston of upper end squeeze cylinder is to when pressing down, abradant fluid medium in through hole flows through through hole and enters in the squeeze cylinder of lower end, treating processing drill in through-holes carries out honing simultaneously, when the piston of lower end squeeze cylinder is upwards pressed, abradant fluid medium in through hole flows through through hole and enters in the squeeze cylinder of upper end, and treating processing drill in through-holes carries out honing simultaneously; The shuttling movement of upper end squeeze cylinder and lower end squeeze cylinder realizes the shuttling movement of abradant fluid medium thus reaches and treat the object that processing drill carries out polishing.
Beneficial effect of the present invention is: structure of the present invention is simple, compact, can realize the extrusion honing processing of drill bit, significantly reduce the surface roughness of drill bit, and improve the surface quality of drill bit, realize the polishing of not damaged drill bit.
