Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1, a floating measurement mechanism, including support frame 1, support frame 1 includes fixed plate 2, fixed plate 2 is connected with reference plate 3 of setting in fixed plate 2 below through a plurality of elastic sliding sleeve subassembly 4, reference plate 3 is connected with displacement sensor 5, displacement sensor 5 sets up on support 6 of fixed plate 2, displacement sensor 5 includes measuring head 7, measuring head 7 is connected with the extension probe 8 that is located reference plate 3, be provided with probe expanding spring 9 on the extension probe 8.

The utility model provides a floating measurement mechanism, its theory of operation is, when measuring the product, reference plate 3 at first with the laminating of product face, continue to push down, reference plate 3 drives elasticity sliding sleeve subassembly 4 and upwards removes, reference plate 3 realizes floating, when product surface slope, reference plate 3 still can with the laminating of product surface, displacement sensor 5 is connected with reference plate 3, guarantee that displacement sensor 5 is fixed with reference plate 3's relative position, the face is measured to 8 contact products of extension probe, probe expanding spring 9 shrink, extension probe 8 is flexible from top to bottom, drive measuring head 7 and shift up, displacement sensor 5 alright with the displacement data of accurate measurement product. The mechanism measures the non-planar product data through the floating mechanism, the measured data repetition precision is high, the mechanism is stable, the efficiency is higher, and the mechanism is more important for products with high measurement requirements.

Preferably, the elastic sliding sleeve assembly 4 comprises a conical sliding sleeve 10 arranged on the fixing plate 2, a guide rod 11 is arranged on the reference plate 3, a conical connecting block 12 located in the conical sliding sleeve 10 is arranged on the guide rod 11, and a buffer spring 13 is arranged on the guide rod 11. During the measurement, benchmark board 3 drives guide bar 11 rebound, and buffer spring 13 contracts, and toper connecting block 12 breaks away from with toper sliding sleeve 10, has the clearance between guide bar 11 and the toper sliding sleeve 10, and benchmark board 3 realizes floating, and when the product surface inclined, benchmark board 3 still can laminate with the product surface.

Preferably, an oilless bushing 14 is provided between the measuring head 7 and the extension probe 8. The oilless bush 14 can be used for freely extending and retracting the lengthened probe 8 in the oilless bush 14, and the oilless bush has good wear resistance and long service life.

Preferably, a limiting block 15 is arranged below the displacement sensor 5. The limiting block 15 can prevent the displacement sensor 5 from being damaged due to excessive movement, and the effect of protection is achieved.
