Make sprayed coating evenly be attached to purpose on the piston in order to reach, endless conveyor is a driving-chain, on every joint driving-chain, be provided with the work piece holder axle, secure fit has from rotary chain wheel on the work piece holder axle, cooperate with rotation chain in being arranged on spray booth from rotary chain wheel, and the work piece holder shaft end is provided with the workpiece clamp prodigiosin and cooperates with workpiece and fixedly connected.Be provided with line shaft in spray booth, be connected with the drive sprocket that cooperates with driving-chain on the line shaft, be provided with the rotation power chain at line shaft simultaneously, the cooperation of rotation power chain is provided with the rotation chain.
On described equipment box, gas extraction system is arranged, gas extraction system respectively with preheating chamber, spray booth and drying chamber UNICOM, the gas outlet of gas extraction system is arranged on the equipment box, and is provided with gas cleaning plant on the gas outlet, can prevent to spray the exhaust emission environment of generation.
In order to determine different dryer preheat temperatures according to different spraying coating process, and the purpose of achieve effective control temperature, all be connected with firing equipment and temperature testing equipment on preheating chamber and drying chamber, firing equipment and temperature testing equipment are electrically connected with controller.
The automatic spraying equipment of the resulting compressor piston of the utility model, can realize that piston cycle repeatedly sprays, when the spraying workpiece, workpiece can at the uniform velocity rotate automatically, guarantee the uniformity of coating. reasonable in design, the driving shaft of the driving shaft of endless conveyor and workpiece rotation is same rotating shaft, has simplified mechanism, provides cost savings; Have only simultaneously and after workpiece enters spray booth, just begin rotation, convenient spraying, saved the energy cost that equipment moves greatly. each firing equipment can be controlled operation effectively automatically and guarantee the effective of oven dry and preheating simultaneously, and equipment box is totally-enclosed seal case, be provided with the exhaust equipment of special use, ability was to airborne release after the waste gas process that the assurance spraying is produced purified environmental sound.

The specific embodiment
The utility model will be further described in conjunction with the accompanying drawings below by embodiment.
Embodiment 1:
As Fig. 1, Fig. 2, shown in Figure 3, the automatic spraying equipment of the compressor piston that present embodiment is described, it mainly comprises equipment box 1, in equipment box 1, be provided with piston loading and unloading mouth 2, spray booth 3 and drying chamber 4, equipment box 1 is totally-enclosed seal case, be provided with preheating chamber 5 in equipment box 1, all be connected with firing equipment and temperature testing equipment on preheating chamber 5 and the drying chamber 4, firing equipment and temperature testing equipment are electrically connected with controller.Be provided with endless conveyor 6 in equipment box 1, endless conveyor 6 is got back to piston loading and unloading mouth 2 through behind preheating chamber 5, spray booth 3 and the drying chamber 4 successively from 2 beginnings of piston loading and unloading mouth; Be provided with spraying equipment in spray booth 3, spraying equipment mainly comprises spray gun 7, regulates the governor motion 8 of spray gun 7 locus, the automatic force feed device 9 of coating and air cleaning unit 10 etc.Endless conveyor 6 is a driving-chain, on every joint driving-chain, be provided with work piece holder axle 11, on work piece holder axle 11, cooperate secure fit to have from rotary chain wheel 12 by key, cooperate with rotation chain 13 in being arranged on spray booth 3 from rotary chain wheel 12 to be in transmission connection, and work piece holder axle 11 ends are provided with work piece holder 19 and are used for installing workpiece and piston.Be provided with line shaft 14 in spray booth 3, be connected with drive sprocket 15 and the rotation power chain 16 that cooperates with endless conveyor 6 by key on the line shaft 14,16 cooperations of rotation power chain are provided with rotation chain 13.
On the described equipment box 1 gas extraction system is arranged, gas extraction system respectively with preheating chamber 5, spray booth 3 and drying chamber 4 UNICOMs, the gas outlet 17 of gas extraction system is arranged on the equipment box 1, and is provided with gas cleaning plant 18 on gas outlet 17.
During work, open firing equipment earlier, equipment box 1 is carried out preheating, after preheating chamber 5 and drying chamber 4 all reach rated temperature, be installed on the work piece holder 19 piston fixing by piston loading and unloading mouth 2, endless conveyor 6 is sent piston into preheating chamber 5 beginning preheatings then, through entering spray booth 3 after preheating chamber 5 preheatings, enter meshing on the spray booth 3 back work piece holder axles 11 from rotary chain wheel 12 and rotation chain 13, make and drive 11 rotations of work piece holder axle from rotary chain wheel 12, thereby drive the piston rotation, spraying equipment uniformly sprays coating on the piston, then under the drive of endless conveyor 6, piston enters drying chamber 4 from spray booth 3, breaks away from from rotary chain wheel 12 and rotation chain 13 simultaneously in this, enters drying chamber 4 oven dry back endless conveyors 6 piston is sent back to piston loading and unloading mouth 2, can take off piston this moment, or do not take off piston and enter into secondary spraying.
When piston moved in equipment box 1, gas extraction system purified and discharges the waste gas that spraying in the totally-enclosed water-tight equipment casing 1 produces.
