Embodiment
Do further explain below in conjunction with the utility model embodiment and accompanying drawing thereof.
From consulting each compressor cylindrical shell mean inside diameter measuring instrument shown in the drawings; Comprise a base 1, supply air line 5 and signal line 6 are housed in the base 1, a upright support 2 on the base 1; Support 2 is provided with three of the cylindrical shells of corresponding regulation and measures following three measurement circumference C1, C2, C3 in the going up of cross section; Each is measured circumference and six gauge heads 4 is installed and is 60 degree distributions, and three cross sections of measuring circumference C1, C2, C3 are identical, and measuring circumference C2 cross section with the middle part is that representative is as shown in Figure 3.Each gauge head 4 comprises 41 and shower nozzles 42 of cambered surface survey.Each cambered surface is surveyed son 41 and is installed in the free end that a resilient strip is surveyed stroma 46, and it is vertical with base 1 to survey stroma 46, surveys stroma 46 other ends and is fixedly attached to support 2.Survey stroma 46 can be provided with an arch portion 462 usefulness and improve elastic deformation.When tested barrel jacket at support 2, the cylinder inboard wall contacting surface is surveyed son 41 compressings and is surveyed stromas 46 free ends and curve inwardly, make survey stroma 46 dorsad the cambered surface one side 461 of surveying son 41 shift to shower nozzle 42.
Each shower nozzle 42 is installed in the nozzle boss 43, and nozzle boss 43 is fixedly connected on support 2, and shower nozzle 42 is parallel with base 1; Each shower nozzle 42 is connected to an air intake opening 44; Generally speaking, shower nozzle 42 preferably is connected with air intake opening 44 through a joint 45, the convenient supply air line 5 that connects.The nozzle 421 approaching survey stromas 46 of shower nozzle 42 cambered surface are dorsad surveyed the one side 461 of son 41, and leave gap 47, survey stroma 46 this gap 47 under natural extended configuration and should be adjusted into 0.2 millimeter.
Each air intake opening piezoelectric sensor 7 of 44 series connection and solenoid valve 8 backs are communicated with supply air line 5.Supply air line 5 is connected to each solenoid valve 8 after inserting external compressed air along separate routes.The solenoid 81 of each solenoid valve 8 inserts power supply, and access way can adopt the solenoid 81 parallel connection backs of each solenoid valve 8 to insert an inductive switch 9 on the base 1, inductive switch 9 and power connection.When tested barrel jacket at support 2, inductive switch 9 can be sensed cylindrical shell and put in place and be, just connects the solenoid 81 of each solenoid valve 8 simultaneously, each solenoid valve 8 is opened the pressurized air of introducing supply air line 5 and is got into shower nozzle 42, measurement can carry out.
The voltage signal of piezoelectric sensor 7 output is connected into signal line 6, and the mode of access is that the voltage signal of each piezoelectric sensor 7 output inserts a control module 10, and the output signal of each control module 10 picks out via signal line 6, the processor of establishing to other.
It is following that present embodiment is measured cylindrical shell mean inside diameter process: when tested barrel jacket at support 2, the cylinder inboard wall contacting surface is surveyed son 41 compressings and is surveyed stromas 46 free ends and curve inwardly, and makes to survey stroma 46 back sides 461 and shift to shower nozzle 42.The nozzle 421 of shower nozzle 42 changes with the gap of surveying stroma 46 back sides 461 47.Simultaneously; Inductive switch 9 is sensed tested cylindrical shell and is put in place; Three cambered surfaces of measuring circumference C1, C2, the last gauge head 4 of C3 are surveyed son 41 and are contacted with cylinder inboard wall, connect the solenoid 81 of each solenoid valve 8, and each solenoid valve 8 is opened the pressurized air entering shower nozzle 42 of introducing supply air line 5.Because nozzle 421 and the gap of surveying between the stroma back side 461 47 change, cause the air pressure of nozzle 421 ejections to change.This pressure changes feedback supply air line 5, and piezoelectric sensor 7 converts this change value of pressure to magnitude of a voltage fluctuation and sends into control module 10 and spread out of through reaching signal line 6, is compared by processor, calculates mean diameter immediately.
