Describe angular instrument with reference to the accompanying drawings in detail according to the utility model.
Shown in Fig. 1-2, the angular instrument according to the utility model comprises: sliding seat 10, driver element 20, bearing 30, cylinder 40, the first links 501 and second link 502.
Specifically, link to each other with sliding seat 10 to drive sliding seat 10 (being the indicated direction of arrow A as shown in fig. 1) or (being the indicated direction of arrow B as shown in fig. 1) rectilinear motion to the right left such as the driver element 20 of ball-screw or linear electric motors etc.
First end of first link 501 links to each other with sliding seat 10 and second end of first link 501 links to each other with cylinder 40 with traction cylinder 40 CWs (being the indicated direction of arrow C as shown in fig. 1) rotation.First end of second link 502 links to each other with sliding seat 10 and second end of second link 502 links to each other with cylinder 40 with traction cylinder 40 (being the indicated direction of arrow D as shown in fig. 1) rotation counterclockwise.
That is to say that as shown in Figure 2, (promptly as shown in Figure 2 ab direction) relatively and front and back (promptly as shown in Figure 2 cd direction) preset distance at interval about the tie point on first link 501 and second link, 502 each comfortable cylinder 40.One end of first link 501 links to each other with sliding seat 10 and the other end at least partly is wrapped on the outer peripheral face of cylinder 40; One end of second link 502 link to each other with sliding seat 10 and the other end at least part be wrapped on the outer peripheral face of cylinder 40 first link 501 and second link 502 in the opposite direction.Link can be wire rope or steel band, and in the utility model, in order to have bigger contact area with the outside surface of cylinder 40 better, to obtain the excellent contact performance, it is preferably then adopting steel band.
When sliding seat 10 was done rectilinear motion left, first link, 501 CWs traction cylinder 40 rotated, and at this moment, the part that first link 501 twines cylinder 40 is then continued to twine cylinder 40 by relieving second link 502.When sliding seat 10 is done rectilinear motion to the right, then be the inverse process of said process, this is understandable for the person of ordinary skill of the art.
Angular instrument according to the utility model; Said sliding seat is rectilinear motion to the left or to the right; Can make said first link draw said cylinder CW rotation or can make said second link draw said cylinder counterclockwise rotates; Be about to rectilinear motion and convert circular motion into, thereby can realize angle location and measurement steadily, accurately.
In other words; The mathematical relation that rectilinear motion converts circular motion into is: θ=L/ Γ; Wherein L is the rectilinear motion distance (arc length that is equivalent to the rotation of cylinder 40) of sliding seat 10, and Γ is the radius of cylinder 40, and θ is that cylinder 40 is because of the sliding seat 10 kinetic anglecs of rotation.After fixing in a manner described such as first and second links of steel band, use driver element 20 to make sliding seat 10 do rectilinear motion.First steel band or second steel band that sliding seat 10 is done on the straight-line while sliding seat 10 drag cylinder 40 rotations.Sliding seat 10 stop motions, then cylinder 40 stop motions, through the location of control sliding seat 10, the location of may command cylinder 40, thereby the location that realization rotatablely moves.Thus, can realize the accurate measurement and the location of angle.
According to an embodiment of the utility model, said angular instrument also comprises first holder 101 and second holder 102.First holder 101 is located at the left side of sliding seat 10 upper surfaces and the right side that second holder 102 is located at sliding seat 10 upper surfaces.Wherein, first end of first link 501 links to each other with first holder 101 and first end of second link 502 links to each other with second holder 102.Advantageously, according to an example of the utility model, bolt is connected between first end of first link 501 and first holder 101, and bolt is connected between first end of second link 502 and second holder 102.Thus, can conveniently install, and connect reliable.
Further, according to some embodiment of the utility model, first holder 101 and second holder 102 and sliding seat 10 are through being weldingly connected.Thus, further facilitate installation.
Further, according to a concrete example of the utility model, first holder 101 and second holder 102 are integrally formed with sliding seat 10.Thus, can reduce parts, further facilitate installation.
According to the angular instrument of the utility model,, can be used for accurate angle location and measurement in conjunction with circle grating or other measurement of angle mechanisms.Steel Belt Transmission itself is exactly transmission very stably; Make that whole rectilinear motion and the transmittance process that rotatablely moves are very steady; Cooperate gapless linear advancement system, help realizing high-precision angle location and measurement, and the cost that greatly reduces simple in structure.
In the description of this instructions, the description of reference term " embodiment ", " some embodiment ", " example ", " concrete example " or " some examples " etc. means the concrete characteristic, structure, material or the characteristics that combine this embodiment or example to describe and is contained among at least one embodiment or example of the utility model.In this manual, the schematic statement to above-mentioned term not necessarily refers to identical embodiment or example.And concrete characteristic, structure, material or the characteristics of description can combine with suitable manner in any one or more embodiment or example.
