The utility model is achieved through the following technical solutions above-mentioned purpose: a kind of circumferentially clamping device for drill bit extrusion honing, comprise two abrasive material transition discs, middle clamping, circumferentially clamping and drill bit clamping block, the cylindrical sleeves of through hole established by described middle clamping in being, two abrasive material transition discs are separately fixed at the two ends up and down of middle clamping, and two abrasive material transition discs and middle clamping form the inner chamber of current downflow on viscosity abrasive material be communicated with up and down, described circumferentially clamping is located in described inner chamber, described circumferentially clamping surrounding is provided with at least three square grooves for drill bit clamping, be provided with semicircular drill bit in described square groove and interior half groove is installed, drill bit clamping block is all fixed with in each described square groove, the drill bit that in described drill bit clamping block is provided with and installs with described drill bit, half groove is corresponding installs half groove outward, interior half groove of described drill bit installation and described drill bit are installed outer half groove and are jointly formed drill bit mounting groove, each described drill bit clamping block is fixed by screws in and circumferentially drill bit is fixed in drill bit mounting groove by screw by clamping, the surrounding of described circumferentially clamping is provided with four fixed strips, and circumferentially clamping is fixed on the abrasive material transition disc of lower end by four fixed strips, and the center of described circumferentially clamping is also provided with the through hole for viscosity abrasive flow on vertical direction.
Further, described square groove is provided with three.Process realized the drill bit of varying number by the quantity of controlling party connected in star while.
Further, the outside of described two abrasive material transition discs is also set with the shell for sealing whole device.
Further, the screw of described fixed drill bit clamping block and circumferentially clamping is the hexagon socket cap head screw of M4 × 10.
The beneficial effects of the utility model are: the utility model is simple and compact for structure, and production cost is low; By the viscosity abrasive material of circular flow through bit face, realize the extrusion honing processing of bit face, reduce the surface roughness of drill bit, improve the surface quality of drill bit, achieve not damaged drilling bit grinding; Related to the drill bit quantity simultaneously processed by the quantity arranging square groove, achieve multiple drill bit and process simultaneously, improve the drill bit working (machining) efficiency adding man-hour relative to single drill bit, and increase substantially the crudy of drill bit.
