Abstract
A lapping tool of a valve block of an air valve of a large compressor is composed of a motor transmission mechanism, an eccentric transmission mechanism, a lapping panel and a balancing iron block. The lapping tool of the valve block of the air valve of the large compressor is characterized in that the balancing iron block is arranged on the lapping panel, an eccentric shaft is arranged below the lapping panel, the eccentric shaft is connected with a coupler through a belt pulley and a triangle belt, one end of a speed reducer is connected with a motor, and the other end of the speed reducer is connected with the coupler. When the lapping tool of the valve block of the air valve of the large compressor is used, the speed reducer is driven by the motor, power is then transmitted to the eccentric rotary shaft through the belt, and then the balancing iron block is driven to achieve the lapping purpose.
Description
Technical field:
The utility model belongs to spare part sealing surface grinding technique field, is particularly assembled in Large-scale Compressor ValvesWhen, gas valve plate sealing milling tool.
Background technology:
During reparation, gas valve plate is often single use to compressor valve, often repairs and once need moreRenew valve block once, and most valve blocks are sealing surface slight damage, slightly cleaning and grind reparation isCan be used, and air valve property indices can be reached.
Majority unit (is put well 0# emery cloths on a flat board, is pinned with hand using the grinding of artificial hand at presentSealing ring is made " 8 " font and is rotated), or processed with surface grinding machine again after leak test after assembling terminates is unqualified.The former hand labor intensity is big, low precision is extremely difficult to quality requirement; The latter is higher to process equipment requirement,Investment is larger.
The content of the invention:
In order to overcome the defect of current Large-scale Compressor Valves valve block lapping mode, the utility model is large-scale pressureWhen contracting machine gas valve plate is repaired, grinding valve block sealing surface provides a kind of centering type milling tool, Neng GouanEntirely, it is accurate, valve block sealing surface is quickly ground to technological requirement size.
The utility model is achieved through the following technical solutions its goal of the invention.
Large-scale Compressor Valves valve block milling tool, by motor transmission mechanism, eccentric drive mechanism and grindingFlat board and balance weight iron are constituted, it is characterized in that: grinding flat plate is provided with balance weight iron, and grinding flat plate lower section is provided with partiallyHeart axle, eccentric shaft is connected by belt pulley and V belt with shaft coupling, and reductor one end is connected with motorConnect, one end is connected with shaft coupling. When using, reductor is driven again by belt power transmission by motorTo eccentric rotary axle, balance weight iron is driven so as to reach the purpose of grinding.
Brief description of the drawings:
Accompanying drawing is the utility model structural representation.
In the accompanying drawings, 1 is motor, and 2 is reductor, and 3 is shaft coupling, and 4 is belt pulley, and 5 is three cuticlesBand, 6 is belt pulley, and 7 is eccentric shaft, and 8 is grinding flat plate, and 9 is the valve block of grinding, and 10 is balance weight iron.
Specific embodiment:
The utility model is described in further detail below in conjunction with the accompanying drawings.
As illustrated, Large-scale Compressor Valves valve block milling tool, by motor transmission mechanism, eccentric gearing machineStructure and grinding flat plate 8 and balance weight iron 10 are constituted, it is characterized in that: grinding flat plate 8 is provided with balance weight iron 10,The lower section of grinding flat plate 8 is provided with eccentric shaft 7, and eccentric shaft 7 passes through the band of 4 and three cuticle of belt pulley 5 and shaft coupling 3It is connected, the one end of reductor 2 is connected with motor 1, one end is connected with shaft coupling 3. When using, byMotor 1 drives reductor 2 again by V belt 5 power transmission to eccentric shaft 7, drives balance weight iron 10So as to reach the purpose of grinding.
When using, 1, grind use gauze or abrasive sand are placed on grinding flat plate 8. 2nd, the valve to be groundPiece 4 is placed in abrasive sand, and balance weight iron 10 is pressed on valve block. (the eccentric shaft and balance weight iron of eccentric drive mechanismCentre bore, radial fit gap is 0.3-0.5mm; 1-2 is left between balance weight iron 10 and grinding flat plate 8Mm gaps). 3rd, starting motor 1 can be ground.
