Component 43 and directive wheel 41.Rolling support component 46 is provided between right clamp assemblies 43 and directive wheel 41.Rolling support component 46
Right clamp assemblies 43 are supported while right clamp assemblies 43 are rotated relative to directive wheel 41.
In central axis 101 radially, the difference L1 of the size of right clamp assemblies 43 and the size of directive wheel 41 be more than etc.
It is less than or equal to 20mm in 10mm.
Directive wheel 41 is arranged between two rolling support components 46.
Two nuts 45 are fixed to the both ends of wheel shaft 44.It is fixedly clamped directive wheel 41, left clamp assemblies 42 and the right side from both sides
Clamp assemblies 43.Further, nut 45 is used to be combined with frame mounting 30, is directed to device 40 and is fixed to frame mounting 30.
Two end caps 47 are respectively overlay in the both ends of wheel shaft 44.Two end caps 47 respectively with left clamp assemblies 42 and right clamping
Component 43 contacts.Active force close to each other is applied to left clamp assemblies 42 and right clamp assemblies 43.So that left clamp assemblies 42
With right clamp assemblies 43 rail is stably clamped from both sides.Wheel shaft 44 is quill shaft.Extension spring 48 passes through wheel shaft 44.The two of extension spring 48
Hold two end caps 47 of fixation respectively.So that two end caps 47 are close to each other.The side of end cap 47 forms jagged.Framework
Device 30 is deeply interior so as to fixing nut 45 to end cap 47 from indentation, there.
Right clamp assemblies 43 include supporting plate 431 and are arranged at multiple balls 49 of supporting plate 431.Ball 49 can be relative
Rotated in supporting plate 431.Ball 49 can rotate with being in contact on the right side of rail relative to rail.Directive wheel 41 is on rail
During rotation, ball 49 avoid supporting plate 431 be directly in contact with rail influence measurement the problem of.
As shown in figure 9, left clamp assemblies 42 include cover plate 421, fixed mount 422, adjustable shelf 423, stage clip 424 and ball
49。
Fixed mount 422 is formed with multiple mounting grooves 4221.The part of adjustable shelf 423 is arranged in mounting groove 4221.Adjustable shelf
423 can move relative to fixed mount 422.Stage clip 424 is located in mounting groove 4221.Stage clip 424 is acted on the application of adjustable shelf 423
Power.Cover plate 421 is fixed to fixed mount 422.Ball 49 is arranged at adjustable shelf 423.Ball 49 can rotate relative to adjustable shelf 423.
When adjustable shelf 423 runs into rail staggered place, i.e., the upper surface of adjustable shelf 423 and other rails when, adjustable shelf 423 is pressed
Power causes adjustable shelf 423 to be slided relative to fixed mount 422, and adjustable shelf 423 shrinks.When adjustable shelf 423 departs from and other rails
During upper surface, adjustable shelf 423 recovers to initial position in the active force of stage clip 424.Ball 49 is in contact with the side of rail, energy
It is enough to be rotated relative to rail.When being rotated on rail, ball 49 avoids fixed mount 422 and is directly in contact with rail directive wheel 41
The problem of causing sliding friction to influence measurement.
As shown in Figure 10, rolling support component 46 includes mounting seat 461, cushion 462, pad 463, bearing 464 and peace
Capping 465.
Cushion 462, pad 463 and bearing 464 are arranged between mounting seat 461 and installation lid 465.Bearing 464 is set
Put and enable mounting seat 461 and installation lid 465 to realize relative rotation.Mounting seat 461 and installation lid 465 are real by bearing 464
Existing rolling friction.Left clamp assemblies 42 and right clamp assemblies 43 are rotated relative to directive wheel 41.
One end of bearing 464 contacts with installation lid 465 to be rotated relative to installation lid 465.The other end of bearing 464 is provided with
Pad 463.Cushion 462 is arranged between mounting seat 461 and pad 463.Cushion 462 applies and bearing 464 to pad 463
The active force of contact.Mounting seat 461 and installation lid 465 can move in the axial direction so that left clamp assemblies 42 and right clamping group
Part 43 can clamp the rail of different in width.
When rail narrower width, extension spring 48 pulls two end caps 47 close to each other.Two end caps 47 are to doing left clamping group
Part 42 and right clamp assemblies 43 apply active force close to each other.Now left clamp assemblies 42 are pointed to the rolling support group in left side
The mounting seat 461 of part 46 applies the active force moved to installation lid 465 direction.Now right clamp assemblies 43 are pointed to the rolling on right side
The mounting seat 461 of dynamic support component 46 applies the active force mutually moved to installation lid 465 direction.The active force overcomes cushion
462 active force causes mounting seat 461 to be moved to installation lid 465.So that left clamp assemblies 42 and right clamp assemblies 43 from two
Side clamping rail.
When rail wider width, rail supports left clamp assemblies 42 and right clamp assemblies 43.Left clamp assemblies 42 and the right side
Clamp assemblies 43 overcome the active force of extension spring 48 to be located remotely from each other.Now active force remote installation of the mounting seat 461 in cushion 462
Lid 465.
Above embodiments of the invention have been carried out with specific and detailed description, can not be therefore understands that for of the invention special
The restriction of sharp scope.It should be pointed out that for the person of ordinary skill of the art, before present inventive concept is not departed from
Put, various modifications and improvements can be made, these belong to protection scope of the present invention.Therefore the protection of patent of the present invention
Scope should be determined by the appended claims.
