Abstract
The utility model provides a drilling-reaming composite tool which has high production efficiency and high processing precision and can save the investment of equipment. The drilling-reaming composite tool comprises a handle part and a blade part, wherein the blade part is provided with a side blade; two edges of the side blade are respectively a guide edge and a drill edge; two parallel channels are arranged on the back of the side blade; and a reaming edge is formed in the joint of the two parallel channel. During processing, according to the rotating direction of the drilling-reaming composite tool, firstly, the drilling edge of the side blade is in contact with a workpiece and reams the workpiece; and the reaming edge is in contact with the part of the workpiece reamed by the reaming edge along with the rotation of the drill reamer; and then the reaming edge starts reaming the workpiece; in this way, two procedures of drilling and reaming are combined into one procedure, so that the time of changing a cutter and secondary clamping is saved, and the production efficiency is improved; and in addition, the drilling edge and the reaming edge are coaxial so as to facilitate ensuring the position degree of secondary hole processing and also be easier to adjust a presetting cutter, therefore, the processing precision can be obviously improved.
Description
Technical field
The utility model belongs to cutter manufacturing technology field, specially refers to a kind of drill reamer.
Background technology
Traditional hole manufacturing procedure is brill, expansion, hinge etc., and the dispersion of operation makes the flow process of machining large workpiece long, and workpiece is difficult to carrying, and process equipment is many, and working (machining) efficiency is low, and machining accuracy also decreases, and impels the increase of processing cost.Because drill bit does not reach machining accuracy, all be first boring in the processing mode of existing hole, the back fraising, twice clamping, twice tool changing, its deficiency that mainly exists has: 1, production efficiency is low, needs twice clamping, twice replacing cutter, workload is big, and is consuming time many; 2, machining accuracy is poor, is unfavorable for guaranteeing the axiality of twice hole processing; 3, equipment has high input, and needs two special purpose machine tool amount cover special fixtures, produces line length.
The utility model content
The purpose of the utility model is to propose a kind of production efficiency height, and machining accuracy is high, the drill reamer that ability saving equipment drops into.
The drill reamer of the utility model comprises shank and blade; Said blade is provided with side edge; Two seamed edges of side edge are respectively guiding seamed edge and drilling seamed edge, and key is that the knife back of said side edge is provided with two parallel grooves, and the joint of said two parallel grooves forms the ream seamed edge.
Add man-hour, according to the direction of rotation of drill reamer, at first the drilling seamed edge of side edge touches workpiece and workpiece is carried out drilling; Rotation along with drill reamer; The ream seamed edge begins to touch workpiece by the position of drilling seamed edge drilling, and the ream seamed edge begins workpiece is carried out ream, and the two procedures that so just realized drilling and reaming focuses in the one procedure; Save tool changing and secondary clamping time, improved production efficiency; Drilling seamed edge and ream seamed edge are coaxial in addition, help guaranteeing the position degree of twice hole processing, and the adjustment tool setting is also easy than imitating, and therefore can obviously improve machining accuracy.Adopt above-mentioned drill reamer can practice thrift a cover special purpose machine tool and a special fixture, and shortened production line, simplified the equipment design, therefore when practicing thrift the equipment purchase cost, improved the reliability of automation control.
Further, said ream seamed edge, guiding seamed edge and drilling seamed edge are parallel to each other, to improve machining accuracy.
Further; The machining accuracy of said ream seamed edge is higher than the machining accuracy of drilling seamed edge; This is because the required precision of Drilling Operations is not high; The last machining accuracy of workpiece is that the precision by the ream seamed edge guarantees, the machining accuracy that suitably reduces the drilling seamed edge helps to reduce the cost that cutter is made, and can not have influence on the final precision of workpiece to be machined.
Further, said side edge is to be made up of along spiral slot or the straight trough that it axially is provided with blade, and promptly side edge can be straight sword or helical edges, with the function and the scope of application that increases drill reamer.
The drill reamer of the utility model can effectively improve the operating efficiency of hole processing through drilling function and ream function are integrated on the same cutter, when guaranteeing product quality, can also reduce production costs.
Description of drawings
Fig. 1 is the structural representation of the drill reamer of the utility model.
Fig. 2 is the head construction sketch map of the drill reamer of the utility model.
Among the figure: 1, shank; 2, blade; 3, side edge; 4, guiding seamed edge; 5, drilling seamed edge; 6, first groove; 7, second groove; 8, ream seamed edge.
The specific embodiment
Contrast accompanying drawing below; Through description, the effect of the mutual alignment between the shape of the specific embodiment of the utility model such as related each member, structure, the each several part and annexation, each several part and operation principle etc. are done further to specify to embodiment.
Embodiment 1:
Like Fig. 1, shown in 2; The drill reamer of present embodiment comprises shank 1 and blade 2; Blade is provided with side edge 3, and side edge 3 is straight swords, and two seamed edges of side edge 3 are respectively guiding seamed edge 4 and drilling seamed edge 5; The knife back of side edge 3 is provided with two the first parallel grooves 6 and second groove 7; The joint of first groove 6 and second groove 7 forms ream seamed edge 8, and wherein ream seamed edge 8, guiding seamed edge 4 and drilling seamed edge 5 are parallel to each other, and the machining accuracy of ream seamed edge 8 is higher than the machining accuracy of drilling seamed edge 5.
Add man-hour, according to the direction of rotation of drill reamer, at first the drilling seamed edge 5 of side edge touches workpiece and workpiece is carried out drilling; Rotation along with drill reamer; Ream seamed edge 8 begins to touch workpiece by the position of drilling seamed edge 5 drillings, and ream seamed edge 8 begins workpiece is carried out ream, and the two procedures that so just realized drilling and reaming focuses in the one procedure; Save tool changing and secondary clamping time, improved production efficiency; Drilling seamed edge 8 is coaxial with ream seamed edge 5 in addition, helps guaranteeing the position degree of twice hole processing, and the adjustment tool setting is also easy than imitating, and therefore can obviously improve machining accuracy.
Adopt above-mentioned drill reamer can practice thrift a cover special purpose machine tool and a special fixture, and shortened production line, simplified the equipment design, therefore when practicing thrift the equipment purchase cost, improved the reliability of automation control.
