Measurement apparatus 20 are fixed to head rod 31.Measurement apparatus 20 are connected to head rod by support spring 22 31.Support spring 22 plays a part of buffering.
One end of head rod 31 is provided with a guider 40.One end of 4th connecting rod 34 is provided with one and is oriented to dress Put 40.Guider 40 is used to be oriented to the motion of rail digital display rangefinder 100.
Rail digital display rangefinder 100 is provided with two guiders 40, and two guiders 40 are separately positioned on measurement apparatus 20 front and rear both sides.I.e. measurement wheel 21 is arranged between two guiders 40 measurement apparatus 20 in other words.
Guider 40 is used to be oriented to the motion of rail digital display rangefinder 100.Guider 40 clamps rail, and along rail Motion.
As shown in Figures 3 to 8, guider 40 includes directive wheel 41, left clamp assemblies 42, right clamp assemblies 43, wheel shaft 44th, nut 45, rolling support component 46, end cap 47 and extension spring 48.
The upper surface of directive wheel 41 and rail.Directive wheel 41 is rotated on rail.More specifically, directive wheel 41 has It is magnetic, can adsorbs on the surface of rail.Left clamp assemblies 42 are located at the left side of rail, the right side of right clamp assemblies 43.It is left Clamp assemblies 42 and right clamp assemblies 43 clamp rail from the left and right sides.Directive wheel 41 is located at left clamp assemblies 42 and right clamping group Between part 43.
Wheel shaft 44 passes through left clamp assemblies 42, directive wheel 41 and right clamp assemblies 43.Left clamp assemblies 42, the and of directive wheel 41 Right clamp assemblies 43 are rotated around wheel shaft 44.Left clamp assemblies 42, directive wheel 41 and right clamp assemblies 43 are around 101 turns of central axis It is dynamic.
Left clamp assemblies 42 can be rotated relative to directive wheel 41.Specifically, rolling support component 46 connects left clamping Component 42 and directive wheel 41.Rolling support component 46 is provided between left clamp assemblies 42 and directive wheel 41.Rolling support component 46 Left clamp assemblies 42 are supported while enabling that left clamp assemblies 42 are rotated relative to directive wheel 41.
Right clamp assemblies 43 can be rotated relative to directive wheel 41.Specifically, rolling support component 46 connects right clamping 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 enabling that right clamp assemblies 43 are rotated relative to directive wheel 41.
In central axis 101 radially, the difference L1 of the size of the size of right clamp assemblies 43 and directive wheel 41 more than etc. 20mm is less than or equal in 10mm.
Directive wheel 41 is arranged between two rolling support components 46.
Two nuts 45 are fixed to the two 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 two ends of wheel shaft 44.Two end caps 47 respectively with left clamp assemblies 42 and right clamping Component 43 is contacted.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 is in contact with the right side of rail, can be rotated relative to rail.Directive wheel 41 is on rail During rotation, ball 49 avoids supporting plate 431 and is directly in contact with rail influences the problem of measurement.
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 applying 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 be rotated 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 that adjustable shelf 423 is 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 directive wheel 41 is rotated on rail, ball 49 avoids fixed mount 422 and is directly in contact with rail Causing sliding friction influences the problem of 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 sets Put and enable that mounting seat 461 and installation lid 465 are realized relatively rotating.Mounting seat 461 and installation lid 465 are real by bearing 464 Existing rolling friction.Enable that 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 can be rotated relative to lid 465 is installed.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 be moved 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 pairs do 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 that mounting seat 461 is moved to lid 465 is installed.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 mounting seat 461 in the active force of cushion 462 away from installation Lid 465.
Above embodiments of the invention have been carried out with specific and detailed description, can not be therefore understands that being special to the present invention 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.
