Abstract
The invention relates to a universal grinding device used for processing valve internal parts in the coal chemical industry and specially used on an engine lathe. The universal grinding device comprises a pneumatic grinder (3), and is characterized by further comprising a base (4); an upper bracket (1) and a lower bracket (2) are respectively mounted on the base (4); the pneumatic grinder (3) passes through the space between the upper bracket (1) and the lower bracket (2) and are clamped by the upper bracket (1) and the lower bracket (2). Proved by trails, the universal grinding device provided by the invention can solve the machining problem of high-hardness valve internal parts, can be mounted on the engine lathe to perform grinding operation to the planes, top circles, inner holes, taper holes and conical surfaces of the high-hardness valve internal parts, and enables the surface roughness of the grinded valve internal parts to be higher than 0.8 while the finishing size precision of the valve internal parts can meet technical requirements.
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 control valve kind of using in coal chemical technology and quantity get more and more, the trim of control valve (sometimes comprising valve flowing channel) will have higher hardness and anti-wear performance.For example adopt the method for surfacing and spraying on base material, its case hardness is reached about HRC72.Can not use cutter to carry out machining through the trim after the surface treatment, and the sealing surface surface roughness is about 0.8, finished surface is endoporus, end face, the conical surface or sphere, can not process at grinding machine, so the bottleneck that is processed into machining of high rigidity trim.
Summary of the invention
The purpose of this invention is to provide a kind of engine lathe special coal Chemical valve internals universal grinding device, can cooperate with engine lathe and realize the high rigidity trim is carried out the grinding operation.
A kind of engine lathe special coal Chemical valve internals universal grinding device, comprise air grinder, its special feature is: also comprise pedestal, be separately installed with upper bracket and lower carriage on this pedestal, described air grinder passes and is held in the middle of this upper bracket and lower carriage.
Wherein between upper bracket and the air grinder, between lower carriage and the air grinder crash roll is installed all.
Wherein crash roll adopts rubber blanket.
Wherein upper bracket is comprised of two U-shaped portion parts, and connects by securing member between these two U-shaped portion parts; And lower carriage also is comprised of two U-shaped portion parts, and also connects by securing member between these two U-shaped portion parts.
Wherein pedestal also is connected by tongue and groove with a grip block.
Through probationary certificate, adopt engine lathe special coal Chemical valve internals universal grinding device of the present invention can solve the machining problem of high rigidity trim, can be installed in that plane, cylindrical, endoporus, taper hole, the conical surface to the high rigidity trim carries out the grinding operation on the engine lathe, trim is carried out grinding, surface roughness reaches more than 0.8, and accurate to dimension can satisfy specification requirement.
Description of drawings
Accompanying drawing 1 is structural representation of the present invention;
Accompanying drawing 2 is cutaway view of the present invention.
The specific embodiment
As shown in Figure 1, 2, the present invention is a kind of engine lathe special coal Chemical valve internals universal grinding device, comprises air grinder 3, also comprises pedestal 4, be separately installed with upper bracket 1 and lower carriage 2 on this pedestal 4, described air grinder 3 passes and is held in the middle of this upper bracket 1 and lower carriage 2.Wherein between upper bracket 1 and the air grinder 3, between lower carriage 2 and the air grinder 3 crash roll 6 is installed all, the crash roll 6 concrete rubber blankets that adopt.
Wherein upper bracket 1 is comprised of two U-shaped portion parts, and connects by securing member between these two U-shaped portion parts; And lower carriage 2 also is comprised of two U-shaped portion parts, and also passes through securing member between these two U-shaped portion parts, and for example bolt connects.
Wherein pedestal 4 also is connected with a grip block 5, specifically is connected with soket head cap screw between pedestal 4 and the grip block 5.Cooperate pedestal 4 and the accurately effect of location of grip block 5 played by tongue and groove.And grip block 5 directly is contained in the tool holder of engine lathe, is similar to clamping one lathe tool.
Grinding attachment of the present invention is made of several parts such as air grinder 3, grip block 5, upper bracket 1, lower carriage 2, pedestals 4, can be directly installed on the common lathe saddle, air grinder 3 has joint directly to connect with source of the gas, and grinding wheel speed can be up to 12000-15000rpm.According to the difference of grinding material, emery wheel can be two kinds of oilstone emery wheel or skives.Of the present invention can be rotated into knife rest arbitrarily angled, can the grinding plane, endoporus, cylindrical, can also grinding at any angle outer cone and inner conical surface.
Claims (5)
