Embodiment 2

[0032] Example 2, which differs from Example 1 in that, as Figure 5 As shown, the rotatable adjustment block 5 is rotatably connected in the slot 21 through the positioning screw 6 . The positioning screw 6 is threadedly connected with the rotatable adjustment block 5 . A positioning hole is provided on one side of the slot 21 of the adjustable adapter plate 2 ;

Embodiment 3

[0033] Example 3, the difference from Example 1 is that, as figure 1 and Figure 5 As shown, the adjustable connecting plate 2 is provided with a locking piece for locking the rotatable adjusting block 5 , and the locking piece is detachably connected with the adjustable connecting plate 2 . Specifically, the adjustable adapter plate 2 is provided with a locking hole 23 that communicates with the card slot 21. The locking hole 23 is used for the locking member to extend into the card slot 21. The inner end of the locking member can be rotatably adjusted. Block 5 fits. In this embodiment, the locking member is a locking screw 8, and the locking hole is provided with an inner thread that fits with the locking screw, so that the locking screw 8 is threadedly connected with the adjustable connecting plate 2, and the locking screw 8 is screwed into After locking the hole, the lower end of the locking screw 8 is used to press the rotatable adjusting block 5 into the slot 21 .

Embodiment 4

[0034] Embodiment 4 is different from Embodiment 1 in that the adjustable connecting plate 2 is provided with an adjusting wrench 7 for rotating the rotatable adjusting block 5 , and the adjusting wrench 7 is movably connected with the adjustable connecting plate 2 . Specifically, the adjustable socket 2 is provided with an adjustment wrench hole 22 that communicates with the card slot 21 , and the adjustment wrench hole 22 is perpendicular to the card slot 21 , and the adjustment wrench hole 22 is used for the adjustment wrench 7 to extend into the card slot 21 Cooperate with the rotatable adjustment block 5. In this embodiment, the lower end of the adjustment wrench 7 is provided with a square column or a hexagonal column, and the rotatable adjustment block 5 is provided with a square hole or a hexagonal hole which is matched with the end of the adjustment wrench 7 . The adjustment wrench hole 22 does not hinder the rotation of the adjustment wrench 7 .

Abstract

The invention discloses a light-load working condition floating adjusting device which comprises an adjustable receiving disc and a three-jaw chuck which are axially connected, the adjustable receiving disc is elastically connected with the three-jaw chuck, and a cam mechanism used for adjusting the three-jaw chuck is arranged on the adjustable receiving disc. The cam mechanisms are arranged at the positions, away from the axis, of the adjustable receiving disc, axial or radial run-out of parts on the three-jaw chuck can be corrected through simultaneous rotation of the cam mechanisms or rotation of part of the cam mechanisms, and adjustment operation is convenient and rapid; a lever dial indicator is matched, so that a clamped part can be accurately and reliably adjusted in the axial direction and the radial direction; the size of the rotatable adjusting block can be changed according to different conditions so as to change the adjustable quantity; through the combined use of the supporting force spring and the fixing screw, the fixing screw can be rotated according to the weight of a clamped part, and the pre-tightening force is reasonably adjusted; the three-jaw chuck is simple in structure and convenient to manufacture, and the clamping universality of the three-jaw chuck is high.

Description

technical field [0001] The invention relates to the technical field of parts clamping, in particular to a floating adjustment device under light load conditions. Background technique [0002] In the processing of parts under light load conditions, especially in wire cutting, EDM and electron beam welding, the clamping accuracy of the workpiece is very high, but mechanical processing, electrical processing, welding and other light loads After the parts are clamped under working conditions, it is difficult for general-purpose fixtures to accurately adjust the parts, making it difficult to correct the axial and radial runout of the parts. SUMMARY OF THE INVENTION [0003] In view of the above-mentioned deficiencies in the background technology, the present invention proposes a floating adjustment device under light load conditions, which solves the problem of difficulty in correcting the axial and radial runout of parts after clamping in the prior art. [0004] The technical...
