Abstract
The utility model relates to a device for drilling a hexagon bolt. The device comprises a clamping block and a clamping mechanism, wherein a mounting hole is formed in the clamping block; a mounting groove communicated with the mounting hole is formed at one end of the clamping block and provided with at least two walls attached to the two opposite sides of a head of the hexagon bolt, and a limit surface at the communicated position of the mounting groove and the mounting hole; a guide hole and a cutter back-off channel are formed on the clamping block and communicated with the mounting groove; and the clamping block and the hexagon bolt are arranged in the clamping mechanism, so that the end face of the hexagon bolt is matched with the limit surface in an extruding mode. During use, a locking hole can be formed on the head of the hexagon bolt through the guide hole by a drill; and meanwhile, the walls of the mounting groove are at least attached to the two opposite sides of the head of the hexagon bolt, so the mounting groove can ensure that the head of the hexagon bolt cannot rotate in the drilling process, and a machining error in the drilling process is avoided.
Description
Technical field
The utility model relates to the drilling equipment of a kind of hex bolts in the field of machining.
Background technology
Hex bolts receives in Aeronautics and Astronautics, defence field widely and using owing to have good location and locking effect.The relevant criterion of hex bolts has special requirement to its accurate positioning property and dimensional uniformity; Just groove position size, position, hole size and the morpheme error of hex bolts all must be controlled in certain margin of tolerance, so the locking hole forming method on the hex bolts seems very important.Because anti-porosity through the relative both sides of the hexagonal shape head of hex bolts, adopts vice to clamp hex bolts the head of bolt is deformed, and in the ordinary course of things; The normal anti-porosity that adopts on Milling Process or the conventional boring processing hex bolts; When adopting Milling Process because the location difficulty of clamping hex bolts on milling machine, thereby the anti-porosity work in-process on the screw can working (machining) efficiency to occur low; High and the big problem of mismachining tolerance of product cost; And adopting conventional boring to add man-hour, hex bolts can't accurately be located on lathe, has caused the morpheme error of the hex bolts of processing bigger.
The utility model content
The utility model provides a kind of drilling equipment of hex bolts, being intended to solve can't pinpoint problem when hex bolts is holed in the prior art.
The technical scheme of the drilling equipment of this hex bolts is following:
A kind of drilling equipment of hex bolts; Said drilling equipment comprises the clamping piece that is used for the clamping hex bolts; Offer the installing hole that is used to supply the hex bolts insertion on the clamping piece; One end of said clamping piece offers the mounting groove that being used to of being communicated with installing hole supplies the head of hex bolts to embed; Said mounting groove has at least two and is used for the cell wall that pastes mutually with the relative both sides of the head of hex bolts; And be used for the confined planes with the head end press fit of hex bolts in mounting groove and the place of connection of installing hole, and offering vertical pilot hole and the cutter relieving passage of cell wall that pastes mutually with the mounting groove and the side of hex bolts on the said clamping piece, said pilot hole and cutter relieving passage are communicated with mounting groove respectively; Said drilling equipment comprises that also being used for that clamping piece and hex bolts are installed in its inside makes the end face of hex bolts and the clamp mechanism of confined planes press fit.
Said clamp mechanism comprises the U-shaped supporting base; Said clamp is in the opening of supporting base; The axis of said installing hole is vertical with the sidewall of supporting base, and said supporting base is equipped with on the side sidewall near said mounting groove and axially revolves the clamping screw of establishing along installing hole.
Said clamp mechanism is a vice, and said clamping piece is in the jaw of vice, and the axis of said installing hole is vertical with the both sides sidewall of vice.
Said mounting groove is that cell wall is used for the in-line mounting groove that pastes mutually with the side of the relative both sides of the head of hex bolts, and perhaps cell wall is used for the hexagon mounting groove that pastes mutually with six sides of the head of hex bolts.
Hex bolts is inserted in the clamping piece that offers installing hole in the utility model; And through the clamp mechanism clamping; Wherein, an end of clamping piece offers the mounting groove that being used to of being communicated with installing hole supplies the head of hex bolts to embed, and on the clamping piece, offers vertical pilot hole and the cutter relieving passage of cell wall that pastes mutually with the mounting groove and the side of hex bolts; In use; Drill bit can be prevented porosity in the head processing of hex bolts through pilot hole, simultaneously, because the cell wall of mounting groove pastes with the side, relative both sides of hexagon bolt head at least mutually; Therefore mounting groove can guarantee that the head of hex bolts can not rotate in boring procedure, thereby has avoided in boring procedure because the mismachining tolerance that the head deflection of hex bolts causes.Therefore this drilling equipment has simple in structure; The characteristics of easy to operate and accurate positioning, and in use, the clamping piece can be prepared a plurality of; Offer different installing holes on each clamping piece; In use, select different clamping pieces for use according to different hex bolts, thereby make working (machining) efficiency improve greatly.

The specific embodiment
The embodiment of the drilling equipment of the hex bolts of the utility model: to shown in Figure 5, this drilling equipment mainly is made up of clamp mechanism and clamping piece 2, wherein like Fig. 1; The clamping screw 4 that clamp mechanism mainly wears on the side sidewall by U-shaped supporting base 3 and supporting base 3 constitutes, and clamping piece 2 just is in the opening of supporting base 3, offers the installing hole vertical with the both sides sidewall of supporting base 35 that supplies hex bolts 1 to insert on the clamping piece 2; Clamping piece 2 offers the in-line mounting groove 5-1 that being used to of being communicated with installing hole 5 supplies the head of hex bolts 1 to embed in the end near clamping screw 4, and in-line mounting groove 5-1 has two cell walls that can paste mutually with the relative both sides of the head of hex bolts 1, and in in-line mounting groove 5-1 and installing hole 5 be communicated with the place can with the confined planes of the head end press fit of hex bolts 1; Offer the vertical pilot hole 6 and cutter relieving passage 7 of cell wall that pastes mutually with in-line mounting groove 5-1 and the side of hex bolts 1 on the clamping piece 2; In use, unclamp the clamping screw 4 on the supporting base 3 earlier, hex bolts 1 is packed in the clamping piece 2; Together be placed on clamping piece that hex bolts 1 is housed 2 and hex bolts 1 in the supporting base 3 then; Tighten clamping screw 4, make the end face and the confined planes press fit of head of hex bolts 1, can hole; During boring; Drill bit penetrates from pilot hole 6, passes after the back arrives cutter relieving passage 7 from the head of hex bolts 1, and drill bit just gets out the anti-porosity 1-1 of an in-line at the head of hex bolts 1; After boring finishes; Unclamp clamping screw 4, take out hex bolts 1, promptly accomplish processing.
