Abstract
The processing method that the invention discloses a kind of shield machine pre-grouting block hole, concrete grammar is as follows: the two pieces of left cushion blocks of left side welding in tool base plate, one piece of right cushion block of the right welding in tool base plate, and on base plate, bore at six M30 tooth hole for the bolt-connection of briquetting；On the basis of frock is completed and clamps the slip casting block do not holed, left side beveled aperture uses path milling cutter milling empty；Internal entity hole, right side tentatively uses Φ 50 drill bit to be drilled into the 300mm degree of depth, then uses Φ 80 drill bit instead and be drilled into the identical or more deeper degree of depth；Use Φ 50 drill bit again instead to drill through to left side milling beveled aperture, after use Φ 80 drill bit instead and drill；Last use boring machine beveled aperture of turning left from entity hole, right side the hole boring of slip casting block to be put in place on the basis of existing bottom outlet, then remove frock, deburring, then machine.The present invention solves the problem that beveled aperture, degree of depth hole and boring chip removal are big with cooling difficulty, improves working (machining) efficiency, reduces expenditure of time and processing charges.
Description
Technical field
The present invention relates to processing method field, refer more particularly to a kind of shield machine pre-grouting block hole
Processing method.
Background technology
Shield machine pre-grouting block through hole length is about 1000mm, and one side is beveled aperture, processing
Difficulty is big.Following two kinds of processing methods are had at present for shield machine pre-grouting block: the first,
It is not processed method design, directly utilizes boring machine and carry out bore hole, but beveled aperture easily crumbles.
The second: being sub-partitioned into two after using the boring of two pieces pre-grouting block entirety, drillable length is about
For 1600mm, but the method need to use depth drill, and existing equipment cannot meet processing, and point
Cut post-treatment location complex.According to common driller, drillable length is long, the breaking of rod easy to break
Head, and it is unfavorable for chip removal and cooling.
Summary of the invention
It is an object of the invention to overcome above-mentioned weak point of the prior art to provide a kind of
Solve the problem that beveled aperture, degree of depth hole and boring chip removal are big with cooling difficulty, improve and add work efficiency
Rate, the processing method reducing the shield machine pre-grouting block hole of expenditure of time and processing charges.
The present invention realizes in the following way:
A kind of processing method in shield machine pre-grouting block hole, it is characterised in that: concrete grammar is as follows:
The first step, frock making: the two pieces of left cushion blocks 2 of left side welding in tool base plate 1, work
One piece of right cushion block 3 of the right welding on dress base plate, it is ensured that slip casting block 7 required processing slip casting block hole
The axis of 71 is on horizontal plane, and bores at six M30 tooth hole on base plate 1 for briquetting 5
Bolt 4 couple；Briquetting 5 is processed into inclined plane shape with slip casting of fitting with the contact surface of slip casting block 7
The inclined-plane of block 7；
Second step, the course of processing: be completed and clamp the base of the slip casting block 7 do not holed in frock
On plinth, left side beveled aperture 72 uses path milling cutter hole milling, by middle milling deep two side milling shallow pattern mould
Intend beveled aperture 72 profile, and stay a small amount of surplus；Internal entity hole 73, right side tentatively uses Φ 50
Drill bit is drilled into the 300mm degree of depth, then uses Φ 80 drill bit instead and be drilled into same depth；Use Φ 50 again instead to bore
Head drills through to left side milling beveled aperture 72, after use Φ 80 drill bit instead and drill；So use drill bit instead also
It is undertaken in two steps the method for drilling to solve hole length well and cross deep and chip removal and cooling is tired
Difficult problem；Boring machine is finally used to turn left tiltedly from entity hole, right side 73 on the basis of existing bottom outlet
Hole 71 boring of slip casting block is put in place by face 72, then removes frock, deburring, then machines.
The beneficial effects of the present invention is: solve beveled aperture, degree of depth hole and boring chip removal with cold
But the problem that difficulty is big, improves working (machining) efficiency, reduces expenditure of time and processing charges.
Accompanying drawing explanation
Fig. 1 present configuration schematic diagram；
Fig. 2 is A-A sectional view in Fig. 1.
Detailed description of the invention
In conjunction with accompanying drawing in detail, the specific embodiment of the invention is described in detail:
As shown in Figure 1 and Figure 2: the processing method in a kind of shield machine pre-grouting block hole, specifically
Method is as follows: the first step, frock making: the two pieces of left cushion blocks of left side welding in tool base plate 1
2, the one piece of right cushion block 3 of the right welding in tool base plate, it is ensured that slip casting block 7 required processing slip casting
The axis in block hole 71 is on horizontal plane, and bores at six M30 tooth hole on base plate 1 for pressing
The bolt 4 of block 5 couples；Briquetting 5 is processed into inclined plane shape with laminating with the contact surface of slip casting block 7
The inclined-plane of slip casting block 7；Second step, the course of processing: be completed in frock and clamp and do not hole
Slip casting block 7 on the basis of, left side beveled aperture 72 uses path milling cutter hole milling, deep by middle milling
Two side millings shallow pattern simulation beveled aperture 72 profile, and stay a small amount of surplus；Internal entity hole, right side
73 tentatively use Φ 50 drill bits to be drilled into the 300mm degree of depth, then use instead Φ 80 drill bit be drilled into identical deeply
Degree；Use Φ 50 drill bit again instead to drill through to left side milling beveled aperture 72, after use instead Φ 80 drill bit bore
Wear；So use drill bit instead and be undertaken in two steps the method for drilling to solve hole length well the deepest
And chip removal and the problem of cooling difficulty；Finally use boring machine from the right side on the basis of existing bottom outlet
Hole 71 boring of slip casting block is put in place by side entity hole 73 beveled aperture 72 of turning left, and then removes frock, goes
Burr, then machine.
