When piston 8 to be detected is circular piston, and above-mentioned piston diameter measuring mechanism 3 works, the piston 8 can be with Only coarse positioning is carried out by piston seam keeper, when piston is transported at piston diameter measuring mechanism 3, the compact heap Actuator 381 drives the compact heap 382 to move down, the clamping piston of compact heap 382, can prevent piston position from offseting；So Afterwards diameter gauge head 37 stretches out, the cylindrical contact with piston 8, so as to measure the external diameter of piston 8.

When piston 8 to be detected is oval piston, corresponding with the piston diameter measuring mechanism 3 treats for placing The device of the piston 8 of detection should select first piston mounting table 21.

Piston 8 on the first piston mounting table 21 carries out coarse positioning by piston seam keeper 214 thereon, when When piston is transported at piston diameter measuring mechanism 3, the compact heap actuator 381 drives the compact heap 382 to moving down Dynamic, the clamping piston of compact heap 382 can prevent piston position from offseting；Then diameter gauge head 37 stretches out, and cylindrical with piston 8 connects Touch (line of the diameter gauge head of piston both sides is approximately perpendicular to the pin-and-hole axis of piston)；Then first piston mounting table 21 turn Platform actuator drives piston seam keeper 214 to turn an angle back and forth (such as ± 15 °), finds the major axis of piston 8, and remembers After record related data, data transfer back to control device (such as industrial computer), and then diameter gauge head 37 withdraws, and compact heap drives Part 381 drives compact heap 382 to move up, and unclamps the piston 8.

In the utility model, the diameter gauge head 37 preferably uses inductance probe, and the movement of diameter gauge head 37 can lead to Cross cylinder or Driven by Hydraulic Cylinder.

In order to prevent, the action being likely to occur is incorrect to cause diameter gauge head 37 to be damaged, on the diameter gauge head 37 Gauge head anticollison block is installed.

Further, the annular groove cooperated in annular groove measurement assembly is also equipped with each described gauge head fixed mount 36 One in gauge head 39, to measure the diameter of ring groove of piston 8.The annular groove gauge head 39 is similar to the setting of diameter gauge head 37, This is repeated no more.

In order to make it easy to understand, being described in detail to the structure of piston diameter measuring mechanism 3 below.

First measurement support 31 of the piston diameter measuring mechanism 3 is fixed by screws on matrix 1, the second guide rail 32 It is fixed by screws on the first measurement support 31 with the 3rd guide rail 33, the second guide rail 32 and the 3rd guide rail 33 are dovetail and lead On the same line, and there is therebetween spacing in rail, the second guide rail 32 and the 3rd guide rail 33, the second guide rail of swallow-tail form is slided On the second guide rail 32 and the 3rd guide rail 33 that the guide rail slide block 35 of block 34 and the 3rd is separately mounted to, second drive component and Three drive components include one end of Top fastening screw 341 and stretching screw 342, the Top fastening screw 341 and stretching screw 342 (the inner) is rotatably mounted on the second guide rail slide block 34 or the 3rd guide rail slide block 35, Top fastening screw 341 and stretching screw 342 other end (outer end) with first measurement support 31 be threadedly coupled, therefore it may only be necessary to tighten Top fastening screw 341, while putting Loose stretching screw 342, or tighten stretching screw 342, while loosening Top fastening screw 341, it becomes possible to realize the second guide rail slide block 34 or the 3rd guide rail slide block 35 integral translation, so as to adjust the relative position of the second guide rail slide block 34 and the 3rd guide rail slide block 35 Put.The gauge head fixed mount 36 includes gauge head fixed mount base plate, gauge head fixed mount top board and connects the gauge head fixture bottom The gauge head fixed mount riser of plate and gauge head fixed mount top board.Gauge head fixed mount base plate is arranged on the second guide rail slide block 34 by screw Or the 3rd on guide rail slide block 35.Diameter gauge head 37 is arranged on gauge head fixed mount riser by gauge head mounting seat, and gauge head Mounting seat can on gauge head fixed mount riser upper and lower adjustment position.Specifically, gauge head mounting seat can be upper and lower by guide rail slide block It is slidably mounted on gauge head fixed mount riser, and jackscrew is installed in the side of gauge head fixed mount riser, the jackscrew can Hold out against gauge head mounting seat.When needing to adjust the height of gauge head mounting seat, the jackscrew is unclamped, after regulation is completed, again Jackscrew is tightened, in case stop bit puts measure error not to causing.

When annular groove gauge head 39 is provided with gauge head fixed mount 36, due to the annular groove narrower width of piston, common inductance Gauge head head (the annular groove gauge head selects inductance probe) cannot be deep in annular groove, it is therefore preferred that in the inductance probe Head on flat gauge head is installed.

As shown in figure 13, the compact heap actuator 381 adopts compression cylinder, compression cylinder to be fixed by screws in first On measurement support 31, and positioned at the top at two middle parts of gauge head fixed mount 36, the piston-rod lower end threaded connection of compression cylinder The lower end for having floating junction 383, floating junction 383 is threaded on little axle 384, lower end and the second bearing 385 of little axle 384 Inner ring be engaged, the outer ring of second bearing 385 is connected with compact heap 382.Such that it is able to realize that compact heap 382 is rotationally installed On compact heap actuator 381.

Held down assembly by arranging, piston can be avoided only to position by seam keeper, be likely to occur when piston is turned round Piston situation about rotating relative to seam keeper, cause the inaccurate situation of piston measured value so as to avoid.
