Abstract
The invention discloses a novel plug valve grinding machine. The grinding machine consists of a base, a coupler, a motor sliding plate, an electric control box, a motor, guide rods, an oil cylinder fixing plate and a lifting oil cylinder. The grinding machine drives a plug body to rotate in a valve body by using a high-torque motor and controls the rotating speed and torque of the motor through the electric control box; acting force between the valve body and the plug body is controlled through the lifting oil cylinder; the lifting oil cylinder is rapidly lifted through inching, a grinding material is coated on the plug body, and goodness of fit and degree of finish between the valve body and the plug body are checked; and the lifting oil cylinder, the motor and a valve are fixed among four guide rods, and the concentricity of the valve body and the plug body in the grinding process is guaranteed.
Description
One, technical field
Project of the present invention relates to the valve-seating technology, improves the valve body and the cock body tapering goodness of fit, fineness, and sealing is more increased.
Two, background technology
Owing to have mismachining tolerance between valve body and the cock body, promptly the tapering between valve body, the cock body is identical so not good, has the slit between face and the face, will leak when pressurization, and valve has had leakage just defective.In order to eliminate the gap between valve body and the cock body, that must be grinding each other between valve body and the cock body.
Beginning is underhand polish, and cock body is fixed on the extension bar, and coated with abrasive material on cock body is put into valve body to cock body again, with the artificial cock body that rotates, to reach the good goodness of fit, fineness.This kind grinding has following shortcoming:
1. efficient is low.Bottleneck during this operation has become to produce in enormous quantities.
2. working strength is big, and workman's physical demands is big.When rotating cock body, need very big muscle power.
3. the phenomenon of killing appears easily.Because be not continuous rotation.
4. quality instability.The fineness and the goodness of fit are bad.
5. production cost height.The workman requires many, and speed is slow.
Three, summary of the invention
Valve grinding machine of the present invention comprises: base, shaft coupling, motor slide plate, electric appliance control box, motor, guide rod, oil cylinder fixed head, lift cylinder.
The objective of the invention is to have overcome technical disadvantages in the production in the past, in present production, demonstrate following advantage:
1. boost productivity, improve production lot, enlarge the production scale.
2. phenomenon can not appear killing.
3. alleviate working strength of workers.
4. improve the quality of product.The stable goodness of fit, fineness of becoming reconciled has been arranged.
5. saving cost.Save human and material resources, financial resources.
Project of the present invention takes following design to reach above purpose:
1 uses high pulling torque driven by motor cock body to rotate in valve body, by PLC control rotating speed of motor and moment of torsion.In PLC, set a rotating speed and moment of torsion in the program according to the valve size size.Minor valve rotating speed height, moment of torsion is little; Big valve rotating speed is low, and moment of torsion is big.When moment of torsion surpassed setting value, motor stopped, and after hydraulic cylinder rose to certain distance, motor rotated again, and hydraulic cylinder descends, and grinds again.Guarantee so can not occur killing between valve body and the cock body, if valve body and cock body are killed, motor is also rotating, and then valve body and cock body can damage, to such an extent as to motor is also burnt.
Replace manually raising labour productivity with motor; Alleviate labor strength; Improved the quality of product; Enlarged the production scale of product; Need artificial quantity also seldom, also save production cost; Production mechanization, automation have been realized.
2. by the active force between lift cylinder application valve body and cock body.Stroke by PLC control rise and fall.Control cock body and be pressed in active force on the valve body.Originally manually be uncontrollable its active force.
3. by the quick rise of crawl lift cylinder, on cock body, be coated with grinding-material, and check the goodness of fit, the fineness of grinding between valve body and cock body.Former cause is manually mentioned, and needs long time and very big muscle power.
4. lift cylinder, motor, valve are fixed between four guide rods, make their mutual stabilities, good rigidly, can not occur rocking.Product can not occur rocking in the middle of fixing it yet, improves product quality stability like this.
Four, grinding machine structure schematic diagram
Below in conjunction with accompanying drawing object of invention is further described:
In the drawings, with four guide rods 8 base 1 and oil cylinder fixed head 9 rigid attachment are got up, guide rod 8 center fixed motor slide 5, are fixed with motor 7 on the motor slide 5, and 7 in motor links to each other with shaft coupling 4, and shaft coupling 4 other ends link to each other with cock body 3.Motor slide 5 links to each other with the expansion link of lift cylinder 10, and lift cylinder 10 is fixed on the oil cylinder fixed head 9.Stretching of PLC electric appliance control box 6 control lift cylinders 10.The flexible motor slide 5 that drives of oil cylinder slides up and down in four guide rods 8, also drives cock body 3 in 2 li rotations of valve body by shaft coupling 4; PLC electric appliance control box 6 is also being controlled the rotation of motor, the moment of torsion and the rotating speed of control motor 7.A locating hole and four guide rods 8 are arranged on the base 1, guaranteed the concentricity of valve body and cock body in the grinder work.
