Abstract
The utility model discloses a kind of integrated drill of the band reaming bit for small-sized foundry goods, belong to machining tool field, it comprises bit part and segment of drillpipe, described bit part is made up of reaming bit and drill two parts, described diameter of ream bit is less than drill, and described reaming bit and drill junction are provided with link slot; Described bit part and segment of drillpipe are provided with conical junction.The purpose of this utility model is to provide a kind of integrated drill of the band reaming bit for small-sized foundry goods, realizes reaming, drilling operation to meet single operation, saves machining period and equipment, space, enhances productivity.
Description
Technical field
The utility model relates to a kind of machining tool, be specially a kind of can to the integrated drill of the reaming simultaneously of the ending cover hole of converted products, boring.
Background technology
In mechanical processing industry, Drilling operation is a kind of conventional machining mode.For small-sized foundry machinery parts, because blank core is little, causes at the bottom of product blank, ensureing that each is through hole, after therefore needing casting to complete, carry out Drilling operation, and need and ensure machining accuracy to need to carry out ream operation before drilling to process.
Because parts are mass production line balance, traditional way is, opens each hole to be processed and realizes reaming, ensure that each hole to be processed is through hole at A district reaming bit brill; And then proceed to B district and carry out Drilling operation, so ensure machining accuracy.But same hole machined twice, not only wastes machining period, and cause the waste in workshop appliance input and circulation space, waste time and energy, production efficiency is low.
Utility model content
The purpose of this utility model is to provide a kind of integrated drill of the band reaming bit for small-sized foundry goods, realizes reaming, drilling operation to meet single operation, saves machining period and equipment, space, enhances productivity.
For realizing above object, the technical solution adopted in the utility model is: a kind of integrated drill of the band reaming bit for small-sized foundry goods, it comprises bit part (21) and segment of drillpipe (22), described bit part (21) is made up of reaming bit (2101) and drill (2102) two parts, described reaming bit (2101) diameter is less than drill (2102), and described reaming bit (2101) and drill (2102) junction are provided with link slot (2103); Described bit part (21) and segment of drillpipe (22) are provided with conical junction (23).
Further, the front end drill basil (a) of described reaming bit (2101) is 120 degree.
Further, described bit part (21) is 30 degree-60 degree with junction cone angle (b) of the conical junction (23) of segment of drillpipe (22).
The beneficial effects of the utility model: 1, once-through operation realizes reaming, drilling operation, save the time of processing small-sized cast casting hole.
2, at same processing stations, processing technology is improved, and does not need extra increment stream to change into this; And do not need additionally to add drilling equipment.
3, ad hoc integrated drill, the connection of two kinds of drill cutter heads and the connection with drilling rod, effectively improve the machining accuracy in hole, ensure that crudy.
Accompanying drawing explanation
Fig. 1 is existing end cap boring procedure schematic diagram.
Fig. 2 is the structural representation of the integrated drill of the utility model.
Fig. 3 is the utility model process schematic diagram.
Described in figure, label character is expressed as: 10, end cap; 101, ending cover hole; 2, integrated drill; 21, bit part; 22, segment of drillpipe; 23, junction; 31, reaming drill; 32, borehole drilling cutter; 2101, reaming bit; 2102, drill; 2103, link slot; A is the drill basil; B is junction cone angle.
Detailed description of the invention
The technical solution of the utility model is understood better in order to make those skilled in the art; below in conjunction with accompanying drawing, the utility model is described in detail; the description of this part is only exemplary and explanatory, should not have any restriction to protection domain of the present utility model.
As shown in Figure 2, assembly relation of the present utility model is: it comprises bit part 21 and segment of drillpipe 22, described bit part 21 is made up of reaming bit 2101 and drill 2102 two parts, described reaming bit 2101 diameter is less than drill 2102, and described reaming bit 2101 is provided with link slot 2103 with drill 2102 junction; Described bit part 21 is provided with conical junction 23 with segment of drillpipe 22.
Preferably, the front end drill basil a of described reaming bit 2101 is 120 degree.
Preferably, described bit part 21 is 30 degree-60 degree with the junction cone angle b of the conical junction 23 of segment of drillpipe 22.
As Fig. 3, specifically add man-hour, only need a processing stations, after fixing end cap 10 to be processed, operation rig drives integrated drill 2 to aim at ending cover hole 101 to be processed to carry out reaming, Drilling operation; The hole of foundry goods first got through by reaming bit 2101, and then drill bit continues to move down, and drill 2102 carries out Drilling operation.
It should be noted that, in this article, term " comprises ", " comprising " or its any other variant are intended to contain comprising of nonexcludability, thus make to comprise the process of a series of key element, method, article or equipment and not only comprise which key element, but also comprise other key elements clearly do not listed, or also comprise by the intrinsic key element of this process, method, article or equipment.
Apply specific case herein to set forth principle of the present utility model and embodiment, the explanation of above example just understands method of the present utility model and core concept thereof for helping.The above is only preferred embodiment of the present utility model, should be understood that, due to the finiteness of literal expression, and objectively there is unlimited concrete structure, for those skilled in the art, under the prerequisite not departing from the utility model principle, some improvement, retouching or change can also be made, also above-mentioned technical characteristic can be combined by rights; These improve retouching, change or combination, or the design of utility model and technical scheme are directly applied to other occasion without improving, and all should be considered as protection domain of the present utility model.
