Abstract
The invention discloses a drilling and reaming combined tool for processing an induction manifold of an automobile engine, which is used for solving the problems of increase in the processing cost, influence on the processing efficiency or complex structure and difficulty in assembling and disassembling due to the split structures of a drill bit and a countersink since the a drill bit of the conventional drilling and reaming compound tool cannot be separated from a countersink and a tool body and the entire drilling and reaming compound tool is required to be discarded if the drill bit is broken or the countersink is worn. The drilling and reaming combined tool is characterized in that a drill bit is arranged in a drill bit installation hole in a tool body; a drill bit cooling liquid hole is formed in the drill bit; three-edge blades are arranged in two blade installing grooves on the tool body; and a main cooling liquid hole which is communicated with the drill bit cooling liquid hole, and a secondary cooling liquid hole which leads to the three-edge blades are formed in the tool body. The drilling and reaming combined tool has the beneficial effects that the drill bit, the countersink and the tool body have split structures, and the installation of the drill bit and the installation of the countersink are not related to each other, so that assembly and disassembly are convenient and rapid, the processing cost is reduced, the processing efficiency is increased, inner cooling processing of the drill bit and the countersink is realized, and the service lives of the drill bit and the countersink are prolonged.
Description
Technical field
The invention belongs to the machining tool technical field, particularly a kind of brill ream combination cutter for the processing automobile motor intake manifold.
Background technology
The cutter that is used for the processing automobile motor intake manifold in the prior art is a kind of brill ream composite cutter, drill bit and countersink and cutter hub all are integrative-structures, be that drill bit and countersink and cutter hub all are inseparable, the technical problem that exists is, because there is the trace projection on the work piece surface, easily cause vibration cutting, and drill bit position intensity a little less than, so Drill Crack often occurs, drill bit in case the fracture, wholely comprise that boring the ream composite cutter countersink and cutter hub partly all and then scrap, processing is forced to stop, and with the brill ream composite cutter that more renews, has not only increased the cost of processing, also since the time of the brill ream composite cutter that more renews longer, thereby also affected the efficient of processing.And, because countersink and cutter hub also are one, also be inseparable, in case countersink is worn, wholely comprise that boring the ream composite cutter drill bit and cutter hub part also all and then scrap, can increase equally the cost of processing, the efficient that also can process owing to the long impact of the time of the brill ream composite cutter that more renews.And, in the prior art cooling of drill bit and countersink being adopted fully and outer water cooling fluid, cooling effect is bad.
Application number is that 94206993.5 utility model patent discloses a kind of Combined drill cutter, this utility model provides a kind of Combined drill cutter, it is by body, drill bit, the composition such as countersink and trip bolt, it is characterized in that being equipped with around the shaft on the body and in arc groove, stretch out by centrifugal force, the anti-countersink of returning by inertia force and with the separate type drill bit of this body and function thread connection, its positive countersink is fixed on the body with trip bolt, anti-countersink is contained in the body lnner arced slot by rotating shaft, drill bit and this body and function thread connection, although drill bit and positive and negative countersink are detachable or change, but its complex structure, only have first den bohrkopf abbauen and rotating shaft, could change anti-countersink, and positive countersink only has one, after a positive countersink is worn, namely need to change or reface, so this Combined drill cutter is fit to that boring is arranged, the occasion that positive and negative spot facing needs, concerning only need to hole and the air intake manifold of automotive engine of positive spot facing and be not suitable for, and its drill bit and body thread connection, bit diameter must be greater than body, if bit diameter less than body, is difficult to guarantee the intensity of drill bit.
Application number is that the utility model patent of 201120088086.X discloses a kind of brill spot-facing plug-in mounting gang tool, comprise drill bit and counterbit, described drill bit and counterbit are split-type structural, although this utility model drill bit or counterbit are replaceable, but, this utility model structure is more complicated, and drill bit and counterbit are sleeved in the drill bushing; Drill bushing is fixed on counterbit on the drill bit by holding screw or pin; This kind bores spot-facing plug-in mounting gang tool and realizes that by drill bushing drill bit is connected with counterbit, and more bit change or counterbit all will unload first drill bushing and just can carry out, and installs then more to bother, and can only hole or the work of spot-facing.
Summary of the invention
Technical problem to be solved by this invention is, overcome the deficiencies in the prior art part, by the improvement to brill ream composite cutter, provide a kind of simple in structure, can guarantee small diameter drill bit intensity, and install, dismantle or change easily, thereby can reduce Costco Wholesale, improve a kind of brill ream combination cutter for the processing automobile motor intake manifold of working (machining) efficiency.
The technical solution used in the present invention comprises cutter hub, be processed with drill bit installing hole and 2 blade installation slots at cutter hub, in the drill bit installing hole on cutter hub drill bit is installed, and by the locking of drill bit lock-screw, be processed with drill bit cooling fluid hole at described drill bit, the 3-edge surgical knife sheet is installed in 2 blade installation slots on cutter hub, and by the insert retention screw lock.
Described 3-edge surgical knife sheet is equilateral triangle, all is processed with blade on three limits of equilateral triangle.
Be processed with the main refrigerant fluid hole that communicates with drill bit cooling fluid hole and lead to the secondary cooling fluid hole of 3-edge surgical knife sheet at described cutter hub.
Compared with prior art, the invention has the beneficial effects as follows:
(1) owing to adopting the structure of boring the ream combination, drill bit tightens together by drill bit lock-screw and cutter hub, the 3-edge surgical knife sheet that forms countersink tightens together by insert retention screw and cutter hub, so drill bit and countersink and cutter hub are split-type structural, if Drill Crack occurs in process, drill bit can be taken off the replacing green bit gets final product, countersink and cutter hub part can continue to use, thereby reduced processing cost, and, owing to only needing to change bit part, and drill bit is to be locked on the cutter hub by lock-screw, as long as pine or tight drill bit lock-screw can be finished dismounting and the installation of drill bit, and be convenient, fast, and drill bit has saved the process of mounting cutter and tool setting, thereby has improved working (machining) efficiency with not related with the installation of countersink.
(2) because countersink adopts 2 3-edge surgical knife sheets, any blade wearing and tearing, can rotate 120 degree angles and use another blade, 3 blades of 2 3-edge surgical knife sheets all wear and tear, the 3-edge surgical knife sheet that just need to more renew, thereby prolonged the service life of countersink, and do not affected the normal use of drill bit and cutter hub.
(3) owing to being processed with the main refrigerant fluid hole that communicates with drill bit cooling fluid hole and leading to the secondary cooling fluid hole of 2 3-edge surgical knife sheets at cutter hub, can realize the interior cooling processing to drill bit and countersink, prolong the service life of drill bit and countersink.
