Description
Technical field
This utility model is related to quartering hammer processing technique field, more particularly, it relates to cylinder body in a kind of large-scale quartering hammer
Piston hole machined equipment.
Background technology
Quartering hammer is a kind of using hydraulic energy as power, drives the piston inside hydraulic cylinder upper cylinder body to carry out with this
Move back and forth, drill steel is beaten by piston, with to drill steel transmit energy, the energy on drill steel again by by impact object absorb,
So as to the important engineering machinery that will be smashed by impact object, it is mainly used in crushing, removing, excavating the works such as hard formation in construction
Make, be typically mounted on excavator, loader or power station, with impulsive force is big, easy to use, mobility is good and efficiency height etc.
Advantage.With the development of hydraulic technique, application of the hydraulic breaking hammer in social all trades and professions is more and more extensive, from initial use
In bore operation and the second-time breakage of large rock mass of mine rock engineering, develop into and have been used to tunneling today, remove
Road and bridge and building, broken Colophonium and concrete road surface and remove smelted furnace cinder and underwater performance etc. is carried out due to its work
The effect played by motility and its raising to labor productivity, increasingly receives the attention of mine and construction department, has
It is widely applied prospect and huge market demand.
In quartering hammer, the major function of cylinder body is the cooperation realization by piston hole with valve opening, as shown in figure 1, due to setting
Valve opening is equipped with, middle cylinder body there must be a part for biasing, causes middle cylinder body of the piston hole actually not at rectangular configuration
Centre.Piston hole is larger relative to valve opening size, causes center of gravity to offset to valve opening place side, and piston hole is being done into one
During step processing, its rotary inertia is uneven, therefore directly cannot process on engine lathe.
When there is larger eccentric force, speed is bigger, and the eccentric rotary inertia of eccentric part is bigger, piston hole during processing
Deflection is bigger, and small-sized middle cylinder body is easier to fix, for large-scale middle cylinder body, if rotary inertia is not balanced, will
Very big error occurs, causes product unqualified.Therefore, in prior art it is mostly be after simple fixing tool clamping,
Eccentric force is balanced by balancing weight, so as to reduce offset during processing.
Such as the Chinese patent of the bulletin of on April 30th, 2014：ZL 201320631864.4, this application case disclose a kind of liquid
Pressure quartering hammer in cylinder body parallel hole clamp for machining, be made up of terminal pad, posting, pressing plate, bolt and balancing weight, posting it is interior
Wall is shaped as solid rectangle, and middle cylinder body is placed in positioning inframe, and posting inside wall height is equal to middle height of cylinder and adds two parallel holes
Distance, the interior wall wide face gap of the wide face of middle cylinder body and frame coordinate and central cross-section and the machine-tool of inwall width revolution
Dead in line；One side in posting inside wall height is equal in middle height of cylinder to the vertical dimension of machine-tool axis of rotation
Simultaneously to the axially bored line distance in two parallel holes, the another side in posting inside wall height to machine-tool axis of rotation hang down
Straight distance is equal to another axially bored line distance of the another side in middle height of cylinder in two parallel holes.
The patent formula seems the processing that can carry out two parallel holes, for small-sized middle cylinder body also substantially can be real
It is existing, but for large-scale middle cylinder body, there is 0.25m in its section2, length is up to 1m, if its gravity is balanced simply by balancing weight,
It is the effect for being extremely difficult to reduce offset.On the other hand, for large-scale middle cylinder body, fixed mechanism needs enough strong
Degree, the precision of size are inseparable with the stability of fixed structure.Even so, even if the program can be applied to large-scale middle cylinder
Body, its side need to coordinate with the sidewall spacers of fixing device, then be also only used for a kind of processing of the middle cylinder body of specification, right
In the slightly different middle cylinder body of size, to also be separately provided its fixer for machining, in terms of cost or efficiency be all either compared with
Big influence factor, actual operability are poor.
