In accompanying drawing, 1 is base, and 11 is sliding slot board, and 21 is the first fixed bar, fixed block centered by 22, and 221 is sliding bar, and 23 is the second fixed bar, and 31 is support bar, and 32 is dial gauge, and 321 is gauge outfit, and 4 is Flexible Connector, and 5 is sprocket wheel.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art are not making under creative work prerequisite, and the every other embodiment obtained, all belongs to scope.
In order to make those skilled in the art person understand the present invention program better, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Please refer to Fig. 1, Fig. 1 is distance over bar detection tool structure schematic diagram provided by the present invention.
A kind of distance over bar cubing provided by the present invention, comprising:
Base 1, described base 1 end face firmware is provided with sliding slot board 11;
Stationary installation, described stationary installation comprise affixed be arranged at described base 1 one end end face the first backstay and be arranged at sliding slot board 11 end face and the center fixed block 22 be slidably connected with described sliding slot board 11 and the second backstay;
Pick-up unit, described pick-up unit comprises and is affixedly arranged at the support bar 31 of described base 1 other end end face and the affixed dial gauge 32 be arranged on described support bar 31, and termination and described second backstay of described dial gauge 32 are fitted.
Wherein, it will be appreciated by persons skilled in the art that the gauge outfit 321 of dial gauge 32 is moveable, the displacement of expression is shown by dial gauge 32.
Wherein, centered by cause, fixed block 22 and described sliding slot board 11 are for being slidably connected, therefore center fixed block 22 can arrange reverse movement along the groove of sliding slot board 11, relative is also slidably connected with sliding slot board 11 because of the second backstay, and therefore the second backstay also can move on sliding slot board 11.
When needs detect sprocket wheel 5 distance over bar, first the central part of sprocket wheel 5 is positioned over center fixed block 22 end face, then according to the size of sprocket wheel 5, slip center fixed block 22 moves in sliding tray version, the first backstay is made to enter between the gear of sprocket wheel 5 side, then adjusting the second fixed bar 23 enters between the opposite side gear of sprocket wheel 5, because of dial gauge 32 gauge outfit 321 with fit with the second backstay all the time, therefore when adjustment the second backstay, also gauge outfit 321 can be driven to move, the distance of gauge outfit 321 movement, shown by dial gauge 32, this just reaches can the object of distance over bar of detection sprocket wheel 5 of fast accurate.
In order to optimize above-described embodiment further, also comprise Flexible Connector 4, described Flexible Connector 4 is affixed to be arranged between described second backstay sidewall and support bar 31 sidewall.Flexible Connector 4 produces mobile for promoting the second backstay on sprocket wheel 5, the second backstay is close to the gear inwall of sprocket wheel 5 all the time, ensures the accuracy measured further.Certainly, Flexible Connector 4 can also play the effect by the second backstay and center fixed block 22 automatic homing, and after sprocket wheel 5 is measured, Flexible Connector 4 is because of the characteristic of self, promote the second backstay to move, indirectly also promote center fixed block 22 and all move to original position.
Further again, described center fixed block 22 end face central part is provided with groove.It will be appreciated by persons skilled in the art that the central part of sprocket wheel 5 own generally understands outwardly convex, can this central boss is set in groove, allow to better fixed chain wheels 5 and can not produce displacement in the process detected.Further, after the central protuberance of sprocket wheel 5 is not arranged at groove, the function automatically detected can be realized, do not need to regulate manually.First, by the second fixed bar 23 and center fixed block 22, stretch out large degree, then be arranged in the pickup groove of center at the lug boss of sprocket wheel 5, cancel tensile force, under the promotion of the automatically intrinsic characteristic of Flexible Connector 4, second fixed bar 23 can move inward, between the gear entering sprocket wheel 5 opposite side, central boss because of sprocket wheel 5 is arranged in the groove of center fixed block 22, therefore sprocket wheel 5 can drive center fixed block 22 generation mobile, after between the gear that the first fixed bar 21 enters sprocket wheel 5 side, automatic stopping is moved, the distance over bar of this to be the number of degrees shown on dial gauge 32 be sprocket wheel 5, which achieves the function that distance over bar cubing detects automatically.
Wherein, described groove floor is provided with the sliding bar 221 be slidably connected with described sliding slot board 11.Slide to do and can ensure that center fixed block 22 is in the process of movement further, the displacement before and after can not producing.Further accurate again testing result.
In the present invention one specific embodiment, described Flexible Connector 4 is spring.Spring is Flexible Connector 4 common in life, and have and draw materials conveniently, low-cost advantage, further reduces the production cost of product.
Distance over bar cubing provided by the present invention, when needs detect sprocket wheel 5 distance over bar, by the second fixed bar 23 and center fixed block 22, stretch out large degree, then be arranged in the pickup groove of center at the lug boss of sprocket wheel 5, cancel tensile force, under the promotion of the automatically intrinsic characteristic of spring, second fixed bar 23 can move inward, between the gear entering sprocket wheel 5 opposite side, central boss because of sprocket wheel 5 is arranged in the groove of center fixed block 22, therefore sprocket wheel 5 can drive center fixed block 22 generation mobile, after between the gear that the first fixed bar 21 enters sprocket wheel 5 side, automatic stopping is moved, at this moment shown on dial gauge 32 number of degrees are the distance over bar of sprocket wheel 5, which achieves the function that distance over bar cubing detects automatically, and wherein, by arranging the dry accuracy ensureing its measurement further that slides in groove floor.
Above distance over bar cubing provided by the present invention is described in detail.Apply specific case herein to set forth principle of the present invention and embodiment, the explanation of above embodiment just understands method of the present invention and core concept thereof for helping.It should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention, can also carry out some improvement and modification to the present invention, these improve and modify and also fall in the protection domain of the claims in the present invention.
