On 310 right side, the right side of the isolation part 42 of a bushing 40 be resisted against on the left side of adjustment part 71, the spiral bullet
Spring 50 is sleeved in the bushing body 41 of two bushings 40 and left and right end bears against the right-hand member in the isolation part 42 of two bushings 40
On face and left side.This makes it possible to, by helical spring 50, realize adjustment part 71 in adjusting lever by turning adjustment part 71
Minute movement on 70, and then the bottom for inclining connecting portion 32 of second support 30 is made relative to the lower mounting portion of first support 10
13 minor rotations, while drive three 20 radial directions of roller preferably to push down to 120 minute movement of slender axles and tightly slender axles quilt
The part of rolling and processing, can either preferably realize the minor adjustment that three rollers 20 are moved to slender axles 120, can improve again
Machining accuracy.
Referring to Fig. 3, the lower end of lower mounting portion 13 of the first support 10 of the floating type fixture and inclining for second support 30
Tiltedly the lower end of connecting portion 32 is connected using pin.This causes the lower end of the lower mounting portion 13 of first support 10 and second support 30
Incline be rotatably coupled relatively simple for structure of lower end of connecting portion 32 and connect reliable.In fact, described floating type
The lower end of the lower mounting portion 13 of the first support 10 of fixture can also be adopted with the lower end of the inclination connecting portion 32 of second support 30
Hinge is rotatably coupled.This is again such that the lower end of the lower mounting portion 13 of first support 10 is connected with the inclination of second support 30
Be rotatably coupled relatively simple for structure of the lower end in portion 32 and connect reliable.
Referring to Fig. 3, the left end of the adjusting lever 70 of the adjustment mechanism is bulb-type, at the top of pin and first support 10
Mounting groove 110 be fixedly connected.The left end of adjusting lever 70 is bulb-type so that the area of the left end of adjusting lever 70 is larger, intensity
Higher, so as to service life is higher, and be rotatably coupled using pin so that the mounting groove 110 at the top of first support 10 is not
Too deep and too wide with being designed to, reduce the volume of first support 10, and then reduce the overall weight of entirely floating type fixture,
Reduce material cost and save energy resource consumption.
Upper surface and mounting groove 110 and the institute of left and right opening that the top of the upper connecting portion 11 of the first support 10 is provided with
The fitting recess 310 for stating the upper surface that is provided with and left and right opening at the top of the connection installation portion 31 of second support 30 is U-type groove (in figure
Not shown, similarly hereinafter).This causes the relatively simple for structure and processing of mounting groove 110 and fitting recess 310 to be easier.
Referring to Fig. 3 and Fig. 4, the right-hand member of the adjusting lever 70 of the adjustment mechanism is provided with external screw thread, and the adjustment part 71 is tune
Whole nut.This causes, and adjustment part 71 is relatively simple for structure, processing is easier and using more convenient.Certainly, the adjustment part
71 can also the tapped sleeve of the person of being.This again such that adjustment part 71 relatively simple for structure, processing be easier and use
More convenient.
The content that this utility model is not described in detail is prior art.
Preferred implementation described above is only the illustration made by this utility model.This utility model institute
Category those skilled in the art can carry out various modifications, supplement or adopt class to described specific embodiment
