Abstract
The utility model discloses a diesel engine cylinder cover valve lapping abrasive machine for the manufacture and repair of large and medium diesel engine. The machine is characterized in that a mandril capable of moving up and down in a sliding pair of a frame is arranged in the frame below the cylinder cover, a circular cam is arranged below the mandril, the rotation of the circular cam drives the mandril to rise slowly and drop rapidly, the mandril pushes the valve to rise, a lifting friction disc is arranged on the frame above the cylinder cover, the lifting friction disc rotates under the drive of a motor and a gear drive and is capable of lifting synchronously with the valve, the lifting friction disc is provided with a spring making the lifting friction disc press the valve under the spring force and driving the valve to rotate through the friction, the mandril drives the valve to rise together with the lifting friction disc when the mandril rises, and the combined effort by the spring arranged on the lifting friction disc and valve weight makes the valve rap the valve pedestal ring on the cylinder cover when the mandril drops. The valve is rising and dropping again and again to rap as rotating arround the cylinder cover to realize the rapping polished dressing to the valve.
Description
The utility model relates to and a kind ofly is used for big-and-middle-sized diesel engine manufacturing or the cylinder cover for diesel engine valve is patted the device of grinding when repairing.
The valve actuating mechanism of big-and-middle-sized diesel engine generally all designs on cylinder head, is provided with valve and valve retainer on cylinder head, needs the valve on the cylinder head is patted grinding in diesel engine manufacturing and repair work, to guarantee that valve is with the air-tightness between valve retainer.Its job requirement is to allow the relative cylinder head of valve bounce valve retainer on the cylinder head while rotating with certain speed and vigor.Method commonly used at present has two kinds: a kind of is by hand valve to be patted grinding, and the shortcoming of this method is that efficient is very low; Another kind method is to adopt rubber suction cups to adsorb valve at the valve top, allows the relative cylinder head of valve be rotated and bounce action by a cover mechanism, the shortcoming of this method be move not too reliable.
The purpose of this utility model provides a kind of cylinder cover for diesel engine valve of new structure and pats grinder, and it can pat grinding to the cylinder cover for diesel engine valve effectively, and reliable operation can guarantee the valve grinding quality effectively.
For achieving the above object, the technical scheme that the utility model is taked is: cylinder head is placed on the equipment rack, below cylinder head, in the frame of valve, be provided with the push rod that can in the frame sliding pair, move up and down, below push rod, be provided with cam disc, cam disc promotes push rod and does the slow plunging motion that rises when rotating under motor reducer drives, push rod promotes valve and rises; On the frame above the cylinder head, be provided with the lifting frictional disk, the rotation and can having spring to make in design on the lifting frictional disk and compress valve under the effect of lifting frictional disk at spring force and drive the valve rotation under motor and gear drive drive of lifting frictional disk with together lifting of valve by frictional force; When push rod rose, push rod promoted valve and the lifting frictional disk rises together; When push rod descends, make valve bounce valve retainer on the cylinder head by the spring and the valve deadweight acting in conjunction that are located on the lifting frictional disk.The relative cylinder head of valve is bounced while rotating back and forth lifting, realizes the beating of valve is ground.
Cylinder head placement location on frame be the valve end face up, the cam disc of employing is an edge cam, push rod and lifting frictional disk quantity are determined according to the valve number, can be realized a plurality of valves on the cylinder head are patted grinding simultaneously.
Do below in conjunction with 1 pair of the utility model of accompanying drawing and to describe in further detail:
Fig. 1 is a cutaway view of the present utility model.
The utility model cylinder cover for diesel engine valve is patted grinder and is made up of these several parts of frame (2) motor reducer (1) cam disc (3) push rod (4) lifting frictional disk (10) spring (11) gear drive (12) pin (13) motor (14) cylinder head supporting carriage (5).
Cylinder cover for diesel engine (7) is placed on the frame (2) by dolly (5) supporting, valve (8) end face up, on the frame (2) of valve (8), be provided with the push rod (4) that can in frame (2) sliding pair, move up and down in cylinder head (7) below, in push rod (4) below a cam disc (3) is arranged, this cam disc (3) is an edge cam, by motor reducer (1) driven rotary, push rod (4) rises by cam disc (3) jack-up, and descending relies on the elastic force of deadweight and spring; On the frame (2) of cylinder head (7) top, be provided with lifting frictional disk (10) and gear drive (12), lifting frictional disk (10) is that a garden is coiled its top one slender axles are arranged, the gear shaft of gear drive (12) is a hollow-core construction, the slender axles of lifting frictional disk (10) can move up and down in hollow gear shaft, the two transmits moment of torsion by pin, being provided with spring (11) on the slender axles of lifting frictional disk (10) is used to make lifting frictional disk (10) to compress valve (8) end face, lower disk surface at lifting frictional disk (10) has rubber blanket to be used to increase the frictional force of same valve (9) end face, valve (8) is gone up over against cylinder head (7) in push rod (4) and lifting frictional disk (10) position, push rod (4) and lifting frictional disk (10) quantity are determined according to the valve quantity that cylinder of diesel engine covers, are generally two or four.
(7) are that cylinder cover for diesel engine (8) is that valve retainer (6) is a valve guide bushing for valve (9) among Fig. 1
When the cylinder cover for diesel engine valve is patted grinding, cylinder head (7) placement location be valve (8) end face up, cylinder head is supported by dolly (5), lifting frictional disk (10) compresses the end face of valve (8) under the effect of spring (11), lifting frictional disk (10) rotates under the drive of motor (14) and gear drive (12) and drives valve (8) rotation by frictional force, when cam disc (3) rotates under the drive of motor reducer (1) simultaneously, promote push rod (4) and do the slow plunging motion that rises, push rod (4) promotes valve (8) and lifting frictional disk (10) rises together.When push rod (4) descended, valve (8) bounced the valve retainer (9) on the cylinder head (7) under the effect of deadweight and spring (11) elastic force.Valve (8) is gone up valve retainer (9) to cylinder head (7) and is carried out reciprocal lifting and bounce while rotating, and promptly finishes the beating grinding work of cylinder head valve.
