Abstract

The utility model discloses a grinder for a valve, which is composed of an electric motor, a steel-wire flexible shaft, a main drive connection cover, a disk type friction eccentric shaft, a centripetal thrust bearing, a grinder shell body, a distance sleeve, a spring pressure cover, a central shaft screw bolt, a centre shaft sliding sleeve, a compression spring, a pressure friction disk cushion ring, a sliding sleeve bearing, a thrust force screw plug, a disk type friction shaft, a pressure friction disk, a central shaft screw nut, an adjustable sliding sleeve screw bolt, a rubber sucking disk, and a screw bolt. A working machine is directly driven through the steel-wire flexible shaft by the electric motor to work. The grinder has small noise and little energy consumption. The utility model has the advantages of compact structure, easy fabrication and low cost.

Description

Grinder for stigma

The utility model is a kind of grinder that is used for keeping in repair and maintaining automobile engine.

At present, being used for the milling apparatus of maintenance automobile engine, valve and large-scale diesel engine has steam-operating grinder and motor-driven mill, the former is because its power resources are air compressor, and air compressor itself must drag with bigger motor, thereby power consumption is high, noise is big, and because the seal request height of source of the gas, has the leakage will the emergent power loss and the situation of fluctuation of service slightly; The latter's structure setting is all complicated, the also not enough light and flexible of operation, and manufacturing cost is very high.

The inventor is at the above-mentioned situation of prior art, in order to cut down the consumption of energy and to improve operating environment, through long-time development, design a kind of new porthole grinder finally, it directly drives working machine work by motor by this simple type of belt drive of Bowden cable.This can not only save the corollary apparatus of steam-operating grinder---air compressor, has reduced its maintenance and fee of material, has saved the energy, but also has removed noise source.In addition,, thereby can produce vertical tremor simultaneously and rotatablely move, be convenient to operation because compact conformation is based in the design of this machine.

Accompanying drawing 1 is the front view of the utility model structural representation, and accompanying drawing 2 is its vertical view.1 motor in the accompanying drawing, 2 Bowden cables, 3 main transmission connecting caps, 4 disc types friction eccentric shaft, 5 radial thrust bearings, 6 engine housings, 7 spacers, 8 spring cappings, 9 central shaft bolts, 10 axis sliding sleeves, 11 compression springs, 12,17 pressure frictional disk packing rings, 13 sliding sleeve bearings, 14 thrust plug screws, 15 disc type friction mandrels, 16 pressure frictional disks, 18 central shaft nuts, 19,22 holding screws, 20 adjustable sliding sleeve bolts, 21 rubber suction cups, 23,24 bolts.Motor 1 connects with Bowden cable 2, the latter is joined by main transmission connecting cap 3 and disc type friction eccentric shaft 4, with bolt 24 main transmission connecting cap 3 is anchored on the engine housing 6, disc type friction eccentric shaft 4 is by a pair of radial thrust bearing 5 supportings, the centre separates mutually with spacer 7, to guarantee the normal operation of bearing.With bolt 23 spring capping 8 is anchored on the top of engine housing 6, its centre studs with axis sliding sleeve 10.Sliding sleeve bearing 13, thrust plug screw 14 and disc type friction mandrel 15 are housed on horizontal axis, and its effect is the size of adjustment center vibrations rotating shaft spin friction power.Central shaft bolt 9, pressure frictional disk packing ring 12,17, pressure frictional disk 16 and central shaft nut 18 organization centers vibrations rotating shaft, after central shaft bolt 9 penetrates pressure frictional disk packing ring 12, pressure frictional disk 16 and pressure frictional disk packing ring 17 and screws with central shaft nut 18, use holding screw 22 stickfast again.Compression spring 11 is loaded between spring capping 8 and the center vibrations rotating shaft, to play the return action of center vibrations rotating shaft motion.Adjustable sliding sleeve bolt 20 revolves due to the bottom of engine housing 6, and its effect is the movement travel that limits axis, and it and axis sliding sleeve 10 are in together on the vertical axis, to guarantee center vibrations rotating shaft two frees degree in vertical direction.After adjustable sliding sleeve bolt 20 revolves calmly, promptly be fixed in the bottom of engine housing with holding screw 19.Rubber suction cups 21 is equipped with in lower end at center vibrations rotating shaft, and its effect is to drive the parts work done, finally finishes the task of grinding.

After opening motor, by disc type friction eccentric shaft 4 and 15 effects of disc type friction mandrel, produce a two-way rotation climbing power, under the effect of compression spring 11, center vibrations rotating shaft moves up and down fast immediately, produces simultaneously to rotatablely move under the effect of pressure frictional disk 16, rubber suction cups 21 drive portholes by the central shaft lower end are done above-mentioned motion, play the effect of grinding porthole, make porthole and gate seat produce the evenly fine and closely woven face of closing of eating, thereby improve the work quality of engine.

The utility model can the continuous running hundreds of hour through fatigue durability test proof, and its each parts are excellent, and the porthole that is ground is on fine and closely woven uniformity coefficient, and this machine is better than existing grinder.The parts manufacturing of this machine is all simple, with low cost with assembling in addition.
