Embodiment
Below in conjunction with accompanying drawing, the present invention is further illustrated.
As Figure 1-4, a kind of high measure device of the present invention, include cover plate 1, sliding tray 2, two transmission shafts 5, sliding shoe 7, optical fiber fixed block 10, optical fiber head 11, axle fixed base plate 12 and benchmark position fixed head 13, described cover plate 1 is screwed and is arranged on sliding tray 2 top, the cavity of described sliding tray 2 is nested is provided with axis fixing plate 3, the counterbore of described axis fixing plate 3 is nested with the first spring 4, and described first spring 4 other end is tight against the bottom face that press against cover plate 1.Cover plate 1 is fixed in frock, when frock presses down, only has the and then motion of cover plate 1 and sliding tray 2, other part be fine motion once, to contact with relevant position is complete.
On two nested bottom faces being fixed on axis fixing plate 3 in transmission shaft 5 one end, two transmission shaft 5 other ends successively through after sliding tray 2, sliding shoe 7 and axle fixed base plate 12 be fixedly connected; Described transmission shaft 5 is also nested with the second spring 6, and described second spring 6 one end is pressed on the bottom face of sliding tray 2, and described second spring 6 other end is pressed on the top end face of sliding shoe 7; The bottom face of described sliding shoe 7 is fixedly installed measuring head 14, and described measuring head 14 other end successively gap is nested in axle fixed base plate 12 and benchmark position fixed head 13.
Described axis fixing plate 3 is also fixedly installed optical fiber stationary shaft 9, and described optical fiber stationary shaft 9 other end is fixedly installed on axle fixed base plate 12 through after optical fiber fixed block 10; Described optical fiber head 11 is fixedly installed on optical fiber fixed block 10; Described sliding shoe 7 one side is fixedly installed the steel disc 8 matched with optical fiber head 11.
Measuring head 14 and two transmission shafts 5 are slidably matched, according to the differing heights of part, steel disc 8 is driven to move, a little opening is had in the middle of steel disc 8, because optical fiber head 11 is relatively motionless, varying in size of the aperture that the diverse location of steel disc 8 makes optical fiber head 11 to respond to, thus calculate the debugging size of part.Benchmark position fixed head 13 can be changed according to different benchmark positions.
Further, it also comprises screw shaft 15, stretches out outside cover plate 1 after described screw shaft 15 one end and axis fixing plate 3 are closely nested, described screw shaft 15 other end through after sliding tray 2 and axle fixed base plate 12 be fixedly connected; The threaded shank of described screw shaft 15 is connected with optical fiber fixed block 10.The height of steel disc 8 can be regulated by screw shaft 15.
Further, the bottom surface of described benchmark position fixed head 13 is provided with benchmark post 13-1, and the xsect of described benchmark post 13-1 is taper.
Principle of work of the present invention: as shown in Figure 2, this device is fixed in frock, the tested part 16 of PCBA board 17 is placed on immediately below benchmark position fixed head 13, the reference point of the benchmark bit alignment PCBA board 17 of measuring head 14, and test bit aims at the position of tested part 16.Frock drives this device to press down point space, and benchmark position and test bit are all contacted with test position completely with the reference point in PCBA board 17.The size of the aperture at this moment responded to according to optical fiber head 11 judges the height of tested part 16.
When using of the present invention, replacing manual measurement in the past by this device, drastically increasing work efficiency, improve output, decreasing Measuring Time and measuring error, reduce further production cost.In addition, this structure is simple, reasonable in design, low cost of manufacture.
The above is only better embodiment of the present invention, therefore all equivalences done according to structure, feature and the principle described in patent claim of the present invention change or modify, and are included in patent claim of the present invention.
