Abstract
The utility model discloses a milling and drilling integrated cutter used for processing salt cores. The milling and drilling integrated tool comprises a milling cutter used for milling a salt core fixing platform and a drilling head used for drilling a salt core positioning hole. The rear end of the milling cutter is fixedly connected with a fixed cutter handle which is coaxially arranged with the milling cutter. A hole, of which the diameter is identical with the drilling head used for drilling the salt core positioning hole, is arranged at centers of the milling cutter and the fixed cutter handle. The drilling head is arranged in holes of the milling cutter and the fixed cutter handle. The fixed cutter handle and the drilling head are fixed via a drill jig. A vertical groove is cut along the axial direction of the cutter handle of the fixed cutter handle.

Description
Technical field
The utility model relates to a kind of refined salt core and bores integrated cutter with milling.
Background technology
At present, interior oil cooling passage aluminium Piston Salt Core is when manufacturing salt core finished product, salt core locating hole and fixed platform generally adopt the mode of separate machined, first use drilling machine refined salt core locating hole, with drilling machine, change milling cutter or use milling car again, according to the manual location milling in the position of salt core locating hole salt core fixed platform.This mode is simple, but production efficiency is low, operation is loaded down with trivial details, the salt core locating hole of producing and fixed platform position degree rely on operator's experience to guarantee, salt core locating hole and fixed platform position degree that different operating person produces differ greatly, in the inner cooling path blank that causes producing, oil cooling passage position flaw detection percent defective is higher, the production in enormous quantities of inadaptable interior oil cooling passage aluminium Piston Salt Core.
Utility model content
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, provide a kind of refined salt core to bore integrated cutter with milling, it can adapt to salt core in enormous quantities and produce, in processing, oil cooling passage aluminum piston blank is cast interior oil cooling passage simultaneously, collection refined salt core locating hole, milling fixed platform and one, can complete milling salt core fixed platform simultaneously, bore salt core locating hole, production efficiency is high.
For achieving the above object, the utility model adopts following technical proposals:
A kind of refined salt core bores integrated cutter with milling, comprise milling salt core fixed platform milling cutter, the rear end of described milling cutter is fixedly connected with a fixedly handle of a knife coaxial with described milling cutter, at described milling cutter and the fixing center of handle of a knife, be processed with one with bore salt core locating hole with drill bit the hole with diameter, in the hole of milling cutter and fixedly handle of a knife, drill bit is set, fixedly handle of a knife and drill bit are fixed by drill jig; Described fixedly handle of a knife is axially cut with the vertical slot of a wide 0.2mm along handle of a knife, utilize the fixedly strain of handle of a knife and the clamping force fixed drill bit of drilling machine, thereby assurance drill bit and milling cutter are coaxial.
Above-mentioned structure by salt core milling milling cutter for fixed platform, bore salt core locating hole and unite two into one with drill bit, once-through operation realizes machining of salt core fixed platform and locating hole simultaneously, guaranteed both relative depths, again 100% assurance the relative position of salt core fixed platform and locating hole meet technological requirement.Salt core fixed platform and the underproof situation of locating hole relative position degree having stopped to produce between different operating person occur, greatly reduce flaw detection percent defective in oil cooling passage position in inner cooling path aluminum piston blank.
Described milling cutter and fixedly handle of a knife are welded to connect, and be welded to connect and realize conveniently, and firmness is high.
Described fixedly handle of a knife is circular, and circular convenient processing, can better keep its circularity, and the axiality while coordinating with its parts.
Described vertical slot is the perforation vertical slot of the wide 0.2mm that cut of line, utilizes feature that 45# steel strain is good and the clamping force fixed drill bit of drilling machine.
The dimensional tolerance in described milling cutter and drill bit aperture is matched in clearance, facilitates installing/dismounting, and does not affect machining accuracy, and drill bit and milling cutter can repeat respectively sharpening and use.
Described milling cutter is cutter block, and cutter head is carbide alloy, and handle of a knife is 45# steel.This kind of material can improve working (machining) efficiency.
The cylindrical of described milling cutter, drill bit cylindrical, fixedly the cylindrical of handle of a knife be, the end of milling cutter circle, for coaxial, can guarantee to add the axiality of product in man-hour.
The end nose circle face of described milling cutter to the cylindrical inclined-plane of milling cutter is knife edge part, the convenient processing to workpiece.
The beneficial effects of the utility model are, the utility model adopts milling salt core fixed platform with milling cutter and bores locating hole and meets the requirements with the relative position that salt core locating platform and salt core fixing hole are coaxially realized in the center of drill bit, once-through operation realizes machining of salt core fixed platform and locating hole simultaneously, the production efficiency being doubled, saved operator 1/2 workload and 1/2 equipment energy consumption simultaneously.Salt core fixed platform and the underproof situation of locating hole relative position degree having stopped to produce between different operating person occur, greatly reduce flaw detection percent defective in oil cooling passage position in inner cooling path aluminum piston blank.Different product is adjusted the relative position of drill bit and milling cutter according to the relative depth of salt core fixing hole and locating platform.
