Description

A kind of portable Counterboring apparatus

Technical field

The utility model is related to a kind of Counterboring apparatus, more particularly, to a kind of portable Counterboring apparatus.

Background technology

Usual reaming is to be carried out by Boring machine, and Boring machine is special processing oil cylinder, cylinder, liquid by the way of The equipment of cylinder pressure deep hole workpiece, can also machining tool spindle hole, blind hole and stepped hole.Lathe can not only undertake various Drilling, boring, but also can carry out rolling and processing, when drilling, use interior chip removal method or external chip discharging method.Bed piece rigidity By force, precision stability is good, and range of spindle speeds is wide, and feed system adapts to various deep hole machinings by AC servo machinery driving The needs of technique, securely and reliably.

But for because when the machinery equipment worn in use repairs reaming, Boring machine can not often make With, because the specification of machine and the time cost of consumption, which define, can not carry out bore hole machining, such as in excavator and loading When the hole machineds such as machine, excavator and loading machine are that one kind being widely used in highway, railway, building, water power, harbour, mine etc. and builds If the earthwork construction machinery of engineering, it is mainly used for the bulk materials such as shovel dress soil, sandstone, lime, coal, also can be to mine Stone, pan soil etc. make lightly digging operations, therefore quality for loading shovel and performance are required for very high requirement.Mesh It is preceding in the prior art, it is various to the Boring mode of loading shovel, but all there is workpiece centering overlong time, Process larger, machining accuracy is low, and tedious process, workload is heavy, needs to expend a large amount of manpower and materials, and the process-cycle is long, efficiency Low defect has seriously affected the production efficiency of loading shovel.Use site need quickly timely correct expand Hole can not be transported on lathe, and existing Boring machine is since volume is big, and installation site is fixed, and cannot be satisfied the needs at scene, Use inconvenience.

And due to there is the position of some holes more special, when reaming, needs to frequently replace cutter shaft, and cutter shaft waits category when mounted In interference fit, dismounting installation is cumbersome, and efficiency is low, and when carrying out reaming, and the positioning of cutter shaft is difficult to determine, is entirely By the empirically determined of operating personnel, for the not poor operator of experience, generally require be repeated several times reaming It can meet the requirements.

Reaming in the prior art is usually all to be transported through long-distance after the equipment of reaming will be needed to remove, transports to work It is being processed using equipment progress inside factory, processing freight charges in this way are higher, and influence normal equipment production, and use this Device structure is also more complicated, such as a kind of 201320486732.7 carrier aircraft scraper bowl boring machining fixture of patent includes tooling platform With bore hole component, fixed on tooling platform to be evenly equipped with cushion block, briquetting component and locating piece, bore hole component is logical with tooling platform 1 Bolt is crossed to be fixedly connected.Boring machine is installed on bore hole component, is used cooperatively with tooling platform, realizes that carrying out bore hole to scraper bowl adds Work.

The Boring machine installed on bore hole component is portable axle sleeve Boring machine, is easy assembling, easy to use, is effectively increased Processing efficiency.

Voussoir is laid on tooling platform, scraper bowl can be pushed up the rear portion of scraper bowl by voussoir during Boring Tightly, it is used cooperatively with cushion block uniformly distributed on tooling platform, briquetting component and locating piece so that scraper bowl is more firm in process Gu.

Cushion block is adjustable cushion block, convenient for during Boring, according to the scraper bowl of different specification size, carrying out height gauge Very little and position adjusting, facilitates following process.

The process of the loading shovel boring machining fixture is：The good scraper bowl of welding is lifted to tooling platform, Positioned by fixing uniformly distributed cushion block, briquetting component and locating piece on tooling platform, i.e., by the sword front edge of board face of scraper bowl with Two locating pieces are adjacent to, successively that required height dimension tune and position is whole good by cushion block according to the specification of scraper bowl, and Scraper bowl is compressed using briquetting component, then is held out against the rear portion of scraper bowl by voussoir, to prevent scraper bowl from being produced during Boring Raw vibration ensures that change in location will not occur during Boring for scraper bowl.Then bore hole component is put to tooling platform, Size is adjusted, the axle sleeve for being used in combination the boring bar of Boring machine prefabricated on scraper bowl is hollow to run several circles, preferably to position bore hole After adjusting, bore hole component is fixed by bolts on tooling platform for the position of component；Finally by mounting flange by boring Hole machine is fixed, and then can carry out Boring to scraper bowl.Long-term accumulation gets off to cause the serious input of freight charges, and increasing makes The financial burden of user is inconvenient.

There is a Patent No. disclosed in the prior art：The patent of 201320649925X, it is specifically disclosed be it is a kind of just Boring machine is taken, includes mainly the main fixed seat of boring bar, the main fixed seat of boring bar is equipped with feeding fixed seat, and feeding fixed seat is equipped with two A feeding guide post being placed in parallel, the tail portion for feeding guide post are equipped with feeding fixed seat, are additionally provided in two feeding guide posts One machine frame of speed reducing machine, machine frame of speed reducing machine lower section are stuck in equipped with pilot hole in feeding guide post, and steel bushing is equipped in pilot hole, is slowed down Two-stage rotary speed reducer there are one being set in machine rack, two-stage rotary speed reducer includes speed reducer end cap, is equipped in speed reducer end cap The gear ring end of vertical shaft, two-stage rotary speed reducer is set there are one motor cabinet, and motor cabinet is equipped with motor, and motor shaft stretches into two-stage rotary It is connect with level-one sun gear in speed reducer, the vertical shaft gear end of two-stage rotary speed reducer connects a boring bar spline housing, boring bar flower Key puts on one boring bar of connection, and boring bar sequentially passes through feeding fixed seat, the main fixed seat of boring bar, and lower end connects a milling cutter, boring A boring bar guide sleeve is set on bar, boring bar guide sleeve one end is set there are one boring bar gland, and boring bar gland is fixed by screws in It is equipped with cup scholar in the main fixed seat of boring bar, in boring bar guide sleeve with boring bar to coordinate, boring bar guide sleeve lower part sets that there are one inclined-planes to coordinate The boring bar pair fixed seat program existing for main problem be exactly the device the kind of drive it is coaxial using motor and boring bar Mode, thus caused by entire length it is long, in practical work process, often result in some places for needing reaming It can not use, because the long equipment of size can not be installed, can not especially used on the hole of the parts of excavator, be excavated Machine is the commonly used equipment of building trade, due to long-term work, many axis hole deformations easy to wear, it is therefore desirable to device to hole Expanding treatment is carried out, axle sleeve is then conveniently inserted in and is utilized again, and existing Counterboring apparatus, such as 201320649925X Patent can not be installed because length is long, while the equipment is excessively complicated, and cost is excessively high.
