Description
Technical field
The present invention relates to a kind of drill bit honing clamping device, refer to a kind of fixture utilizing the abrasive flows of constant pressure and flow velocity to carry out drill bit extrusion honing especially.
Background technology
Extrusion honing is a kind of surface finish in modern age and the new technology of deburring, adds have good effect to the polishing of mould and part or deburring.Extrusion honing technology is exactly a kind of polishing method utilizing the abradant fluid medium (viscosity abrasive material) with certain pressure and flow velocity to carry out honing, Honing process is a kind of a kind of high-efficiency machining method making workpiece machining surface reach high accuracy, great surface quality, high life, effectively can improve precision and reduce surface roughness, removing the burr etc. on the surface of spark machined.The feature of extrusion honing is that efficiency is high, quality good, equipment is simple, easy to operate.Extrusion honing technology can realize thoroughly removing burr completely, thus improves surface quality, extends part service life.
At present, drill bit emery wheel carrys out grinding, improves surface quality.In order to better reduce surface roughness, improve the effect of polishing and deburring.For the deficiencies in the prior art, the present invention utilizes the abradant fluid medium (viscosity abrasive material) with certain pressure and flow velocity to carry out a kind of polishing method of honing, design and made a set of drill bit extrusion honing device, realize constant pressure and the flow velocity of abrasive flows, to reduce bit face roughness, improve honing quality, extend drilling life of bit.
The Main Function of fixture, except installation, Clamp blocks, accommodation medium guide it to pass through except part, the more important thing is the flow process wanting control medium.Because fluid the most easily passes through the path that distance is the shortest, cross section is maximum, resistance is minimum.In order to boot media is cut to required part position, can carry out at some position of fixture stopping, turn round, disturb, force viscoplasticity abrasive material by the position of required processing.Because this technique uses semifluid abrasive material, during polishing, corresponding grip device must be designed according to the design feature of different part, so as abrasive material can accurately, reliably by the polished surface that will pass through.Thus the application result of this technology depends on that grip device designs to a great extent, and the quality of grip device design directly affects quality of finish.
Summary of the invention
In order to improve bit face quality, extending drill bit and processing service life, the invention provides a kind of reduction bit face roughness, and improve the surface quality of drill bit and the drill bit extrusion honing fixture realizing constant abrasive material flow velocity of working (machining) efficiency.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of drill bit extrusion honing fixture realizing constant abrasive material flow velocity, comprise transition disc and abradant fluid medium under transition disc on abrasive material, straight pin, upper clamping, lower clamping, abrasive material, the two ends up and down of described lower clamping to be fixedly connected with on abrasive material transition disc under transition disc and abrasive material respectively, and lower clamping is interfixed by transition disc under transition disc on straight pin and abrasive material and abrasive material; Under described lower clamping and abrasive material, transition disc is also provided with the through hole for abradant fluid medium circulation, described abrasive material is crossed scale and be provided with the semi-circular groove circulated for abradant fluid medium, described semi-circular groove is communicated with described through hole, and the through hole under semi-circular groove and lower clamping and abrasive material on transition disc forms the abradant fluid medium flow cavity sealed; Described upper clamping is positioned at the through hole of described lower clamping and upper end is fixedly connected with transition disc on abrasive material, and the bottom of described upper clamping is provided with the circular hole for clamping drill bit, and the both sides of described circular hole are provided with the trip bolt for securing drill bits.
Further, the through hole both sides of described upper abrasive material transition disc are also provided with the semi-circular groove be communicated with described through hole.Semi-circular groove can make abradant fluid medium better flow in described through hole, enables abrasive material transition disc better locate clamping and lower clamping simultaneously, thus makes the sealing that whole system keeps good.
Further, described lower clamping is all fixedly connected with by two steady pins with transition disc under abrasive material with transition disc on abrasive material.
Further, described semi-circular groove is symmetrical a pair.
Further, on abrasive material, on transition disc, the inlet area of two semi-circular groove is equal with the circular hole discharge area of lower transition disc.Equal inlet area and discharge area enable abradant fluid medium along the at the uniform velocity honing back and forth of the drill bit hand of spiral.
Operation principle of the present invention is: drill bit is arranged in the circular hole of clamping, by both sides screw fastening, hole between the upper and lower transition disc of abrasive material and lower clamping is full of abradant fluid medium, by the abradant fluid medium of upper and lower piston back and forth repeatedly in squeezing through-hole, the sealing of fixture inside must be effectively.
By drill bit being pressed in upper clamping, abradant fluid medium being transported in upper and lower squeeze cylinder, when upper piston presses down, entering pushing cylinder promotion lower piston by workpiece and moving down; When lower piston pushes away, the abradant fluid medium of lower squeeze cylinder enters upper squeeze cylinder through workpiece again, promotes upper piston moves, thus reaches the object of drill bit being carried out to polishing.
Special feature is, exported by the circular hole of the semi-circular groove entrance of upper transition disc, lower transition disc, design with the uiform section of lower clamping inner circular aperture passage, make abradant fluid medium substantially along the at the uniform velocity honing repeatedly back and forth of drill bit hand of helix, the constant pressure of abrasive flows and flow velocity can be realized.
Beneficial effect of the present invention is mainly manifested in: the extrusion honing processing realizing drill bit, reduces bit face roughness, and improves the surface quality of drill bit, realize not damaged drilling bit grinding.Can process multiple drill bit, more bit change is flexible, and working (machining) efficiency is high simultaneously.
