According to the requirement self design instrument of product drawing, and this mode takes time and effort and expends resource.
Utility model content
The purpose of this utility model be for above-mentioned the deficiencies in the prior art there is provided one kind it is easy to use, work well
Valve manufacture special counterboring instrument.
What the technical solution of the utility model was realized in：A kind of valve manufacture special counterboring instrument, including taper shank, institute
State taper shank and spot-facing cutter head is removably installed by attachment structure；What the spot-facing cutter head was connected by handle of a knife, with handle of a knife consolidates
Tool rest and some blades composition for being circumferentially distributed in solid tool rest upper surface；The handle of a knife, blade and solid tool rest are integrated into
The overall structure of type；The blade and handle of a knife are orthogonal.
In a kind of above-mentioned valve manufacture special counterboring instrument, the attachment structure by being located at taper shank lower surface vertically
Counterbore, the pin hole for being located on the taper shank of counterbore both sides and cooperating and the latch composition being located in pin hole；In handle of a knife
Provided with the connecting hole being engaged with latch, the latch end, which is sequentially passed through after pin hole, connecting hole, opposite side pin hole, to be locked
Fasten.
In a kind of above-mentioned valve manufacture special counterboring instrument, bulge loop is formed on the taper shank in pin hole, in latch
It is provided with the annular groove being adapted with bulge loop.
In a kind of above-mentioned valve manufacture special counterboring instrument, the blade block number is 2-4 blocks；Each solid tool rest footpath in blade edge
To being uniformly distributed.
The utility model is used after said structure, and spot-facing cutter head is fixed on taper shank by way of latch, conveniently more
Also good with rigidity while changing spot-facing cutter head, shock resistance is strong, the advantages of processing simple；By the way of latch, coordinate many
The spot-facing cutter head of different size is planted, a variety of spot-facing techniques is can be suitably used for, makes the utility model applicability wider；Blade straight forming
On solid tool rest, cutting control performance is good, processes workpiece excellent performance；The bulge loop and annular groove being engaged are set, limit can be played
Position, fixation.
Brief description of the drawings
The utility model is described in further detail for embodiment in below in conjunction with the accompanying drawings, but does not constitute to this reality
With new any limitation.
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of spot-facing cutter head；
Fig. 3 is the close-up schematic view at A in Fig. 1.
In figure：Taper shank 1, counterbore 1a, pin hole 1b, bulge loop 1c, spot-facing cutter head 2, handle of a knife 2a, solid tool rest 2b, blade 2c, company
Meet hole 2d, latch 3, annular groove 3a.
Embodiment
Refering to shown in Fig. 1 to Fig. 3, a kind of valve manufacture special counterboring instrument of the present utility model, including taper shank 1, taper shank 1
It is convenient to be connected with drilling machine, it is preferred to use Mohs 4# or Mohs 5# using Morse's taper.The taper shank 1 passes through attachment structure
Spot-facing cutter head 2 is removably installed；Solid tool rest 2b and edge that the spot-facing cutter head 2 is connected by handle of a knife 2a, with handle of a knife 2a
It is circumferentially distributed in some blade 2c compositions of solid tool rest 2b upper surfaces；The handle of a knife 2a, blade 2c and solid tool rest 2b are integrated into
The overall structure of type；The blade 2c and handle of a knife 2a are orthogonal.It is preferred that, the blade 2c different according to the requirement of spot-facing
Block number is 2-4 blocks；Each blade 2c is along the radially uniform distributions of solid tool rest 2b.Using this structure, handle of a knife 2a, blade 2c and solid tool rest
2b overall structure makes spot-facing cutter head have good anti seismic efficiency, and blade symmetry is distributed on solid tool rest 2b, reaches processability
It can require, meet 16~φ of bolt hole φ 36 spot-facing technique, cover the corresponding spot-facing work of valve DN100~DN500 bores
Skill.
It is preferred that, the attachment structure is main by being located at the counterbore 1a of the lower surface of taper shank 1 vertically, being located at counterbore 1a both sides
On taper shank 1 and the pin hole 1b and the latch 3 that is located in pin hole 1b that cooperate are constituted；It is provided with handle of a knife 2a with inserting
The connecting hole 2d that pin 3 is engaged, the end of latch 3, which is sequentially passed through after pin hole 1b, connecting hole 2d, opposite side pin hole 1b, locks
Fasten, latch 3 through pin hole 1b end are connected with nut thread.By way of latch and pin-and-hole coordinate, side
