Utility model works process：

A kind of plunger bushing of the utility model produces special end face Plane surface grinding machine in the course of the work, and plunger bushing blank is put into Groove 2252 is put, inductor 2255 senses plunger bushing blank and transmits a signal to PLC electric cabinets, and PLC electric cabinets start the 5th gas The piston rod of cylinder 2254 stretch out and drive promote body 2253 move backward, promote body 2253 promote plunger bushing blank enter pair In the deep-slotted chip breaker 2225 for the blank fixed mechanism 222 answered, then the piston rod of the 5th cylinder 2254 is retracted, meanwhile, PLC electric cabinets Start the motor of conveying plate chain 221, motor, which drives conveying plate chain 221 to move a beat backward, will be fixed with plunger The blank fixed mechanism 222 of set blank takes away feed mechanism 225 and by next band of blank fixed mechanism 222 to feed mechanism 225 are fed, when motor drives conveying plate chain 221 to move the six beat quantity for reaching PLC electric cabinets and setting backward (the plunger bushing blank that conveyer 223 is transported to device for grinding 21 has been completed to polish, and is transported mechanism 223 and takes base away afterwards Six dummy receptacles 2211 after part fixed mechanism 222 just run to the blank fixed mechanism 222 that is fixed in framework 2239 Lower section simultaneously corresponds), PLC electric cabinets count beat number and start the second cylinder 2234, the piston of the second cylinder 2234 again Bar stretches out and drives crossbeam 2235 to move downward, and crossbeam 2235 drives the second track 2237, the 4th cylinder 22313 and trapezoid seat 22310 move downward, and the second track 2237 drives framework 2239 to move downward by the second sliding seat 2238, until the second cylinder 2234 piston rod it is fully extended (now, the plug socket 2229 of the blank fixed mechanism 222 in framework 2239 it is fully-inserted pair In the dummy receptacle 2211 answered), then PLC electric cabinets start piston rod retraction the second fastening body of drive of the 3rd cylinder 22311 22312 move downward the compression released to train wheel bridge 2222, and then the piston rod of the 4th cylinder 22313 of PLC electric cabinets startup is stretched Go out and promote two counter motions of the second sliding seat 2238, the second sliding seat 2238 drives framework 2239 to move, until the 4th gas The piston rod of cylinder 22313 is fully extended (now, the lower frame of framework 2239 removes completely from the lower section of lower plate 2221), then The piston rod that PLC electric cabinets start the first cylinder 2233 stretches out and drives the first sliding seat 2232 to travel forward, until the first gas The piston rod of cylinder 2233 is fully extended (now, to be fixed from six blanks for being fixed with plunger bushing blank of the process of feed mechanism 225 Mechanism 222 is just corresponding with framework 2239), then the piston rod of the 4th cylinder 22313 of PLC electric cabinets startup is retracted and pulled Two move toward one anothers of the second sliding seat 2238, the second sliding seat 2238 drive framework 2239 to move, make the lower frame of framework 2239 Enter the lower section of lower plate 2221 and standing groove 22314 corresponds with lower plate 2221, then PLC electric cabinets start the Two cylinders 2234 and the 3rd cylinder 22311, the piston rod of the second cylinder 2234 are retracted and drive crossbeam 2235 to move upwards, crossbeam 2235 the second tracks 2237 of drive, the 4th cylinder 22313 and trapezoid seat 22310 move upwards, and the second track 2237 passes through second Sliding seat 2238 drives framework 2239 to move upwards, and framework 2239 drives six blank fixed mechanisms for being fixed with plunger bushing blank 222 depart from conveying plate chain 221, and the piston rod of the 3rd cylinder 22311 stretches out and drives the second fastening body 22312 to move downward and press On train wheel bridge 2222, plunger bushing blank is pressed abd fixed on lower plate 2221 by train wheel bridge 2222, and then PLC electric cabinets start The piston rod of first cylinder 2233 is retracted and drives the first sliding seat 2232 to move backward, until the piston rod of the first cylinder 2233 It is fully retracted, now, the blank fixed mechanism 222 in framework 2239 corresponds with device for grinding 21, and PLC electric cabinets open Dynamic device for grinding 21 is worked, and (conveyer 223 is transported after the counting of PLC electric cabinets reaches six beat quantity of setting again The plunger bushing blank for delivering to device for grinding 21 has been completed to polish, and is transported after mechanism 223 takes blank fixed mechanism 222 away Six dummy receptacles 2211 just run to the lower section for the blank fixed mechanism 222 being fixed in framework 2239 and one-to-one corresponding), fortune Mechanism 223 is sent to repeat aforesaid operations, the plunger bushing blank for having completed to polish from blank fixed mechanism 222 by manually removing.

The operation principle of device for grinding 21：PLC electric cabinets start the 6th cylinder 201, and the piston rod of the 6th cylinder 201 is stretched completely Go out and promote pulling body 202 to travel forward, then PLC electric cabinets open the electromagnetic valve 2114 on air inlet 216, compressed air Entered from air inlet 216 in pneumatophore 215, pneumatophore 215 extends forward in the presence of compressed air, pneumatophore 215 Front end promotes slide 213 to travel forward, and slide 213 drives emery wheel 219 to travel forward by motor 218, until emery wheel 219 contradicts On the end to be polished of plunger bushing blank, now, emery wheel 219 can not move forward, so as to which pneumatophore 215 also will not continue to Extend forward, when showing that the air pressure in pneumatophore 215 reaches certain value on air gauge 2110, air gauge 2110 transmits a signal to PLC electric cabinets, the electromagnetic valve 2113 that PLC electric cabinets are closed on air inlet 216, and start motor 218 and drive emery wheel 219 to rotate The end of plunger bushing blank is polished, during emery wheel 219 polishes to plunger bushing blank, due to plunger bushing blank End can be worn away certain thickness, can extend certain length forward so as to the front end of pneumatophore 215, due to pneumatophore 215 Front end extend forward, the air pressure in pneumatophore 215 can diminish, when showing the air pressure in pneumatophore 215 on air gauge 2110 (complete to polish in the end of plunger bushing blank) when being reduced to certain value, air gauge 2110 transmits a signal to PLC electric cabinets, PLC electricity Control case controlled motor 218 is stopped, meanwhile, start the 6th cylinder 201, the piston rod of the 6th cylinder 201 is retracted and pulls drawing Kinetoplast 202 moves backward, and when the front end of slotted eye 203 contacts with connecting rod 204, pulling body 202 drives connecting rod 204 to transport backward Dynamic, connecting rod 204 drives slide 213 to move backward by body 214, until the piston rod of the 6th cylinder 201 is fully retracted.With Prior art is compared, can be simple in construction, easy to use, and continuous production is good, and the uniformity that product polishes is good, reduces artificial labor Fatigue resistance.

Above-described embodiment be to explanation of the present utility model, be not to restriction of the present utility model, it is any new to this practicality Scheme after type simple transformation belongs to the scope of protection of the utility model.
