Abstract
The present invention relates to a kind of engine lathe special coal Chemical valve internals universal grinding device.Including air grinder (3), being characterized in: also include pedestal (4), this pedestal (4) is separately installed with upper bracket (1) and lower carriage (2), described air grinder (3) passes and held in the middle of this upper bracket (1) and lower carriage (2).Test proves that, the engine lathe special coal Chemical valve internals universal grinding device using the present invention can solve the machining problem of high rigidity trim, may be mounted at, on engine lathe, the plane of high rigidity trim, cylindrical, endoporus, taper hole, the conical surface are carried out grinding operation, trim is carried out grinding, surface roughness reaches more than 0.8, and accurate to dimension can meet technology requirement.
Description
Technical field
The present invention relates to a kind of engine lathe special coal Chemical valve internals universal grinding device.
Background technology
Along with the regulation valve kind used in coal chemical technology and quantity get more and more, in the valve of regulation valve
Hardness that part (sometimes including valve flowing channel) comparison to be had is high and anti-wear performance.For example with at base
Surfacing and the method for spraying on material, can make its case hardness reach about HRC72.Through surface
Trim after reason can not use cutter to carry out machining, and sealing surface surface roughness is 0.8
Left and right, finished surface is endoporus, end face, the conical surface or sphere, can not be processed on grinding machine,
Therefore the bottleneck being processed into machining of high rigidity trim.
Summary of the invention
It is an object of the invention to provide a kind of engine lathe special coal Chemical valve internals universal grinding device,
Can coordinate realization that high rigidity trim is carried out grinding operation with engine lathe.
A kind of engine lathe special coal Chemical valve internals universal grinding device, including air grinder, its
It is particular in that: also include pedestal, this pedestal is separately installed with upper bracket and lower carriage, described
Air grinder passes and held in the middle of this upper bracket and lower carriage.
Wherein between upper bracket and air grinder, it is mounted between lower carriage and air grinder
Crash roll.
Wherein crash roll uses rubber blanket.
Wherein upper bracket is made up of two U-shaped portion parts, and by fastening between these two U-shaped portion parts
Part connects；And lower carriage is also made up of two U-shaped portion parts, and also lead between these two U-shaped portion parts
Cross securing member to connect.
Wherein pedestal is also connected by tongue and groove with a grip block.
Test proves that, use the engine lathe special coal Chemical valve internals universal grinding dress of the present invention
Put the machining problem that can solve high rigidity trim, may be mounted on engine lathe hard to height
The plane of bottom valve internals, cylindrical, endoporus, taper hole, the conical surface carry out grinding operation, to trim
Carrying out grinding, surface roughness reaches more than 0.8, and accurate to dimension can meet skill
Art requirement.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of the present invention；
Accompanying drawing 2 is the sectional view of the present invention.
Detailed description of the invention
As shown in Figure 1, 2, the present invention is a kind of engine lathe special coal Chemical valve internals universal grinding
Device, including air grinder 3, also includes pedestal 4, and this pedestal 4 is separately installed with upper bracket 1
With lower carriage 2, described air grinder 3 passes in the middle of this upper bracket 1 and lower carriage 2 and is pressed from both sides
Hold.Wherein between upper bracket 1 and air grinder 3, between lower carriage 2 and air grinder 3
Being mounted on crash roll 6, crash roll 6 specifically uses rubber blanket.
Wherein upper bracket 1 is made up of two U-shaped portion parts, and by tight between these two U-shaped portion parts
Firmware connects；And lower carriage 2 is also made up of two U-shaped portion parts, and between these two U-shaped portion parts
Also by securing member, such as bolt connects.
Wherein pedestal 4 is also connected with a grip block 5, specifically with interior between pedestal 4 and grip block 5
Hex screw connects.Coordinated by tongue and groove and play the effect that pedestal 4 is accurately positioned with grip block 5.
And grip block 5 is directly installed in the tool holder of engine lathe, it is similar to clamp a lathe tool.
The grinding attachment of the present invention by air grinder 3, grip block 5, upper bracket 1, lower carriage 2,
Several parts such as pedestal 4 are constituted, and can be directly installed on common lathe saddle, and air grinder 3 has
Joint can be directly connected to source of the gas, and grinding wheel speed may be up to 12000-15000rpm.According to grinding material
The difference of matter, emery wheel can be oilstone emery wheel or skive two kinds.The present invention's can be with knife rest
It is rotated into arbitrarily angled, it is possible to grinding plane, endoporus, cylindrical, it is also possible to outside grinding at any angle
Cone and inner conical surface.
